DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Reference is now made to Figs. 1 - 7, which illustrate a remotely monitorable valve cover assembly 100, constructed and operative in accordance with a preferred embodiment of the present invention, suitable for use with a tank truck 102, as seen in Fig. 1.
As seen in Figs. 2 and 3, the remotely monitorable valve cover assembly preferably comprises a conventional latchable valve cover subassembly 104, which is arranged for threadable engagement with a conventional valve outlet 106, a flange 108 of which is in turn bolted onto a flange 110 of a valve outlet pipe 112 by bolts 114.
In accordance with a preferred embodiment of the present invention, valve cover monitoring assembly 120 is welded or otherwise fixedly attached to valve cover subassembly 104 and a monitoring unit 122 is bolted or otherwise fixedly attached to flange 108 by some of bolts 114. Monitoring unit 122 is preferably a model IG-FLH-40- XXX or a model IG-FL-40-XXX, commercially available from Hi-G-Tek Ltd. of Israel, where the XXX designates the communications frequency in MHz.
As seen in Figs. 3 and 4, valve cover monitoring assembly 120 preferably comprises a generally planar mounting ring 130 which is welded about its outer circumference to a planar surface 132 of valve cover subassembly 104, the weld being indicated by reference numeral 134. Ring 130 is preferably also welded about its inner circumference to planar surface 132 of valve cover subassembly 104, the weld being indicated by reference numeral 136.
Fixedly mounted to an integral extension 140 of ring 130 is a generally cylindrical monitoring pin receiving assembly 142 which preferably includes a cylindrical housing 144 in which is seated a compression spring 146 which provides a resilient support for a pin socket element 148, which in turn supports a permanent magnet
150 in predetermined propinquity to a bore 152 which defines a pin socket. A transverse pin 154 extends through element 148 into slidable engagement with a pair of slots 156 formed in cylindrical walls of housing 144 to retain pin socket element 148 against
disengagement with housing 144, while allowing axial movement of element 148 relative to housing 144 along a longitudinal axis 158 along which extends bore 152.
Monitoring unit 122 is preferably fixed to a pivotable mounting base 170 which is in turn pivotably mounted onto a mounting plate 172 by a hinge 174 for pivotable movement about an axis 176 which preferably extends perpendicularly to axis
158. Mounting plate 172 is preferably formed with slots 178 which adjustably accommodate bolts 114, when plate 172 is bolted to flange 108.
Figs. 5 A, 5B and 5 C illustrate alignment of monitoring unit 122 upon initial mounting of monitoring unit 122 onto valve outlet 106. Figs. 5A and 5B together illustrate rotation of monitoring unit 122 about axis 176 such that a longitudinal axis 180 of a pin 182 of monitoring unit 122 lies parallel to axis 158. Figs. 5B and 5C together illustrate displacement of monitoring unit 122 in a plane perpendicular to axis 158 such that axes 180 and 158 become coaxial. Following the alignment steps illustrated in Figs.
5A - 5C, the bolts 114 are preferably tightened to maintain axes 180 and 158 in mutual coaxial alignment.
Reference is now made to Figs. 6 and 7, which illustrate mutual alignment of the monitoring unit 122 and of the cylindrical monitoring pin receiving assembly 142 when the valve cover 104 is attached to the valve outlet 106. It is seen that an end of pin 182 of monitoring unit 122 is seated in bore 152 and that pin 182 is in predetermined propinquity to magnet 150. This propinquity is sensed by monitoring unit 122, which provides a remotely monitorable indication when such propinquity does and does not exist. In this way, removal of the valve cover 104 is remotely monitorable.
Reference is now made to Figs. 8 - 14, which illustrate a remotely monitorable valve cover assembly 200, constructed and operative in accordance with another preferred embodiment of the present invention, suitable for use with a tank truck 202, as seen in Fig. 8.
As seen in Figs. 9 and 10, the remotely monitorable valve cover assembly preferably comprises a conventional latchable valve cover subassembly 204 which is arranged for threadable engagement with a conventional valve outlet 206, a flange 208 of which is in turn bolted onto a flange 210 of a valve outlet pipe 212 by bolts 214.
In accordance with a preferred embodiment of the present invention, valve cover monitoring assembly 220 is integrally formed with cover subassembly 204 and a monitoring unit 222 is bolted or otherwise fixedly attached to flange 208 by some of bolts 214. Monitoring unit 222 is preferably a model IG-FLH-40-XXX or a model IG-FL-40- XXX, commercially available from H-G-Tek Ltd. of Israel, where the XXX designates the communications frequency in MHz.
As seen in Figs. 10 and 11, fixedly mounted to an integral extension 240 of cover subassembly 204 is a generally cylindrical monitoring pin receiving assembly
242 which preferably includes a cylindrical housing 244 in which is seated a compression spring 246 which provides a resilient support for a pin socket element 248, which in turn supports a permanent magnet 250 in predetermined propinquity to a bore 252 which defines a pin socket. A transverse pin 254 extends through element 248 into slidable engagement with a pair of slots 256 formed in cylindrical walls of housing 244 to retain pin socket element 248 against disengagement with housing 244, while allowing axial movement of element 248 relative to housing 244 along a longitudinal axis 258 along which extends bore 252.
Monitoring unit 222 is preferably fixed to a pivotable mounting base 270 which is in turn pivotably mounted onto a mounting plate 272 by a hinge 274 for pivotable movement about an axis 276 which preferably extends perpendicularly to axis 258. Mounting plate 272 is preferably formed with slots 278 which adjustably accommodate bolts 214, when plate 272 is bolted to flange 208. Alternatively, hinge 274 may be obviated and base 270 may be fixedly mounted onto mounting plate 272.
Figs. 12A and 12B illustrate alignment of monitoring unit 222 upon initial mounting of monitoring unit 222 onto valve outlet 206. Figs. 12A and 12B together illustrate displacement of monitoring unit 222 in a plane perpendicular to axis 258 such that a longitudinal axis 280 of a pin 282 of monitoring unit 222 and axis 258 become coaxial. Following the alignment steps illustrated in Figs. 12A & 12B, the bolts 214 are preferably tightened to maintain axes 280 and 258 in mutual coaxial alignment.
Reference is now made to Figs. 13 and 14, which illustrate mutual alignment of the monitoring unit 222 and of the cylindrical monitoring pin receiving assembly 242 when the valve cover 204 is attached to the valve outlet 206. It is seen that
an end of pin 280 of monitoring unit 222 is seated in bore 252 and that pin 280 is in predetermined propinquity to magnet 250. This propinquity is sensed by monitoring unit 222, which provides a remotely monitorable indication when such propinquity does and does not exist. In this way, removal of the valve cover 204 is remotely monitorable. It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described above. Rather the scope of the present invention includes both combinations and sub-combinations of features described and shown as well as modifications and variations thereof which would occur to a person skilled in the art upon reading the foregoing description and which are not in the prior art.
