Abstract

1,241,156. Lamps. HERBERT WETTIG & CO. K.G. 9 Feb., 1970 [1 Aug., 1969], No. 6069/70. Heading F4R. [Also in Division H4] To enable the reaction of a reader to an advertisement &c. to be remotely observed or recorded in secret, the reader 14, Fig. 1, is seated at a mirror-topped table 13 on which the advertisement, together with others, is placed and the reflected reaction of his eyes, together with the read subject matter, is observed by an optical or television camera 23 hidden in a standard lamp 12. The camera records through a gauze or like grid 29 but is rendered invisible to the reader by the glare from surrounding light sources 27. The light sources may be upper and lower annular fluorescent tubes 30, 37 and the camera may be housed in a compartment 22 of the opaque shade 17 formed by upper and lower partitions 19 and 20. The peripheral part of the compartment 22<SP>1</SP> in the alternative embodiment shown in Fig. 6 may be formed by a cylinder separate from the translucent shade 17<SP>1</SP> and a third or middle fluorescent tube 35 placed in the annular space between the cylinder and shade. The lower tube at least may be replaced by a spray of light bulbs.
