Abstract: 490,365. Imitation fires. BERRY, H. H. Feb. 10, 1937, Nos. 3939 and 20099. [Class 126] In an electric fire, Fig. 1, in which translucent imitation fuel 3, with a surface shaped irregularly to form fuel knobs, is arranged in front of a reflector 7 with irregular dull patches 8 to increase the flame effect produced by flickering light falling on the reflector, the fuel is hollow on one side and is so located relatively to the reflector 7 that the images produced by the reflector of the fuel knobs and of the hollow side are both visible from the front of the fire, causing apparent hollows between the knobs themselves and the images, from which flames appear to emanate. In an alternative form, Fig. 4, the reflector 7, instead of or as well as having irregular dull patches, has flame-shaped openings and is backed by a second reflector 11. The openings have partly or wholly reflecting flanges 10. The hollow side of the fuel 3 may be closed by a wire gauze or other screen which allows the reflector to form an image of the hollow side. The reflectors 7 may have an undulating surface, or may be curved vertically or bent, and may have their upper parts treated, e.g. with cellulose, to match the rest of the fire. Translucent diffusing screens may be arranged between the flicker-producing device 12 and the reflector 7. The dull parts 8 of the reflector, and /or the openings in the reflector, may be such that the flicker device is not reproduced in the reflector.

Abstract: 981,161. Track apparatus. GENERAL PRECISION Inc. Feb. 9, 1961 [Feb. 15, 1960], No. 4912/61. Heading B7N. [Also in Division H4] In an interrogator-responder system of the type disclosed in Specification 917,755, e.g. for identifying railway wagons, an interrogator 101 transmits a carrier plus a plurality of simulated sidebands which are supplied by separate oscillators 102 to 105 and supplied to an output coil 107. At the responder 108 a circuit L1, C1 receives the interrogator signal and crystal filters F1, F2 remove two of the " sidebands." The signal is demodulated by a diode X1 and capacitor C2 and the composite voltage resulting from the " sidebands " (except the two filtered out) superimposed on a direct component resulting from the detection of the carrier operates a transistor oscillator T1 to provide a response signal consisting of a carrier modulated by the audio-frequencies not filtered out and characteristic of that responder. The response signal is picked up by a coil 112, amplified at 113 and supplied to detectors 117 to 119, one for each " sideband " transmitted from 101. The outputs of carrier oscillator 102 and " sideband " oscillators 103 to 105 are respectively combined in frequency changers 114 to 116 to provide corresponding audio-frequencies which after filtering at 131 to 133 are used as reference frequencies at the detectors 117 to 119 to check the phase and frequency relationships of the incoming signals, any received signals which do not have the correct frequency and phase relationships being rejected. The resulting signals are supplied via filters 130 to 132 and rectifiers 133 to 135 to a register 136. The output of amplifier 113 may be used to provide an A.G.C. potential which is compared with a reference potential and used to control the gain of the amplifier 106 and circuitry providing register clearing as disclosed in Specification 917,755.
