Filed: 1975-03-24
Abstract: 1453406 Reflex cameras ASAHI KOGAKU KOGYO KK 24 March 1975 [23 March 1974] 12221/75 Heading G2A A single-lens reflex camera having a pentaprism 5 and a focusing plate 4 has a light-sensitive element 7 on which the image on the focusing plate is refocused by a lens system 6, the lightsensitive area 8 of element 7 being smaller than the refocused image, so that element 7 responds to only a part of this image. As shown in Fig. 3, the whole image on plate 4 is represented by the full-line area A-E, but only the inner part 10 is received by the sensitive area 8 of element 7. This allows of "spot" photometry, in which priority in light measurement is given to a particular part, usually the central area. As seen in Fig. 2, there may be two light-sensitive elements 7, disposed on either side of the eye-piece 9. The overall schematic arrangement can be seen in Fig. 1 (not shown), in which light entering through the objective lens (1) is reflected by a mirror (2) through a Fresnel plate 3 on to the focusing plate 4. The element 7 may be movable along the axis of lens elements 6, so  that, if required, the whole area A-E may be received by the sensitive area 8.

Abstract: 694,439. Automatic exchange equipment. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. May 15, 1951 [May 26, 1950], No. 13237/50. Class 40 (iv). [Also in Group XXXVI] In a ribbon multipling cable having its conductors arranged in zig-zag formation from edge to edge of the cable and connecting loops in all the conductors at each successive appearance along one edge, the transposition of the conductors of any pair is effected at an appearance of the conductors at the edge remote from the connecting loops so that not more than two conductors are included in the thickness of the cable at any point. The transpositions of different conductors are effected according to different plans, all of which involve transpositions which are symmetrical about the middle of the bank multiple run along the switch shelf, and are different for adjacent pairs of conductors. Adjacent pairs are preferably transposed at different points to reduce cross talk to a minimum, and a 22-conductor cable may be arranged so that five pairs with varying transposition plans lie between two that have the same plan. In a stack of ribbon cables, similarly placed pairs in adjacent cables are differently transposed. In a three-pair cable, the conductors 1, 2 of pair A are transposed at alternate back folds BF1, BF3 without crossing each other. The connector loops at positions SP2, SP3 are crossed outside the body of the ribbon so that the loops appear in the proper order. The conductors 3, 4 of pair B are transposed at BF2, the loops being crossed at SP3. The conductors 5, 6 of pair C are crossed at BF1, and the loops crossed back at SP2, SP3. Specifications 468,844 and 678,042, [Group XXXVI], are referred to.

Title: Improvements in or relating to radar system
IPC: G01S7/20
Filed: 1951-06-05
Abstract: 716,122. Radio navigation. GILFILLAN BROS., Inc. June 5, 1951 [July 21, 1950], No. 13291/51. Class 40 (7). The invention relates to radio systems, and in particular to ground control approach systems, wherein indications of polar co-ordinate type are presented on the screen of a cathode-ray tube. According to the invention in such a presentation the range scale is made non-linear, for example logarithmic or experimental, and varies according to the angle of the sweep on the tube screen. The description relates to a G.C.A. system in which the elevation and azimuth .displays 311 and 310 are combined on the face of a single tube with different displaced :origins 313. The range marks 317-323 are arranged to be straight lines across both displays and the angular scale may also be expanded. It is suggested that, where # is the scan angle of the aerial and ° the angle of the display scan from a corresponding reference direction, for the azimuth display tan ° =3 sin # and for the elevation display tan °=10 sin #. Fig. 1 shows a simplified diagram of the system in so far as one of the displays is concerned. The antenna 204 is scanned, for example, through a 20 degrees angle in azimuth and radiates pulses generated by transmitter 214 modulated by pulse modulator 211 under the control of timing circuit 210. Received echo ;signals pass through the receiver 507 and are applied to the grid 208 of the display cathode ray tube to brighten the trace. Timing circuit 210 triggers square wave generator 212 which triggers the flyback blanking circuit 221. The amplitude of the waveforms eventually applied to the orthozonal defecting coils 225 and 226A is determined by the position of the aerial system through the voltage tapped off potentiometer 310 by arm 311 moved in synchronism with the aerial. The voltage, fed through expansion and tilt control potentiometers 314 and 315 produces an amplified voltage variation in line 304 and an amplified and inverted voltage variation on line 307. The potentials of these lines are maintained near zero by the conduction of valves 228 and 229 but at the beginning of each sweep the square waveform output of generator 212 cuts the valves off and the potentials 304 and 307 rise experimentally due to the charging condensers C1112 and C1119. These experimental waveforms are applied through deflection coil amplifiers 250 and 251 to provide the required non- linear sweep on the display tube. Constant currents from units 226B and 225B may be used to offset the origin of the ;trace and adjustable linearity controls 501 and 502 be associated with the amplifiers 250 and 251.
