Abstract: 1,061,815. Electric analogue calculating. SPERRY RAND CORPORATION. Dec. 8, 1965 [Dec. 11, 1964], No. 52029/65. Heading G4G. [Also in Division H4] In a PPI radar display apparatus the range sweep signal has a non-linear characteristic varying as a function of the relative bearing. As described, a conventional pulse radar scans in azimuth and a PPI display is produced on a CRT screen in which a target having an actual range of Ra is shown as having a modified range # of where # is the relative bearing of the target and M is a constant. The display is of the perspective type with a vanishing point, corresponding to infinite range, determined by the value of M. It may be off-centred, preferably with the origin near the lower edge of the CRT screen, and a calibrated perspective graticule may be superimposed (Fig. 2, not shown). Collision avoidance is facilitated since the proximities, velocities, and sizes of targets are exaggerated as they come closer and also as they lie more nearly dead ahead. Circuitry operating upon the output of a normal range sawtooth generator 13 comprises conventional analogue computer components, that is, log circuits 16, 24, an antilog circuit 25, a bias or addition circuit 23, and a Ra subtraction circuit 19. The analogue of - is M derived from a voltage divider 17, and the value of M may be altered by means of a knob Ra 20. Multiplication of - by cos 0 is effected M by a resolver 21, the rotor which is mechanically coupled to the radar aerial 11. The signal corresponding to # is fed to a resolver 26, also driven from the aerial 11, which produces the X and Y deflection signals for a CRT 15.

Abstract: 1275402 Delivering coins SABLOC AUTOMATIC SYSTEMS Ltd 23 May 1969 [23 Feb 1968] 53307/67 Heading G4V Apparatus for controlling the dispensing of coins from a magazine, e.g. in the form of change from a coin-freed vending machine, comprises a stop which normally prevents passage of coins through the magazine outlet, at least two members which normally allow such passage and means for moving the stop and a selected one of the members so that the member prevents passage of all coins except a selected number to be dispensed and the stop permits passage of the selected number. As shown, the apparatus is associated with the magazine exit channel formed by upper and lower spacers 22, 15 and side plates 10 and 11. Two members 34, 34<SP>1</SP> are selectively actuatable according to whether it is required to dispense one or five coins. When one of two actuating solenoids 30 (or 30<SP>1</SP>) is energized, member 34 (or 34<SP>1</SP>) moves through holes 27 (or 27<SP>1</SP>) in side plates 10, 11 to block passage of all coins save the one (or the five) nearest stop 40. Stop 40 is mounted on a spring-loaded plate 38 which is moved by the inserted member 34 (or 34<SP>1</SP>) to withdraw the stop from its operative position and permit the coin (or the five coins) to roll through exit 24 under gravity. Plate 38 may be gravity-loaded, rather than spring-loaded. Additional members 34 may be provided. If the coins are so shaped that no suitable gap exists between them for insertion of member 34, then the latter may be arranged to pass through a hole in the coin or abut the side surface of the coin. In the latter case, a cranked extension of member 34 may be arranged to operate stop-carrying plate 38.
Patent GB-535200-A (GB)
Abstract: 535,200. Twisting wires together. HARRIS, E. Feb. 28, 1940, No. 3718. [Class 83 (iv)] In securing parts together by twisting round them a tying wire, such as in securing a flexible hose on the metal spigot of a canister, or affixing eye-pieces, valve-holders, &c. to flexible facepieces of respirators, the twisting is effected first under a relatively heavy tension and then under a lighter tension. The twisting hook l is mounted on a shaft d rotated by a handle e and pushed forward by a treadle f and crank g against the action of a heavy spring i. The hook is fixed at o to a slidable tube p, which carries a pin s engaging a longitudinal slot t in the shaft d, the tube being pressed rearwardly by a light spring r. The canister c is secured in a screw-adjusted jig b and a wire n with loop ends m is wound once or twice round the hose. The treadle is pressed so that the hook is moved towards the loops, the parts being adjusted so that with the treadle fully depressed the hook requires to be moved a further distance independently of the shaft against the action of the spring r. The hook is then engaged with the loops, the treadle released and the shaft given two or more turns so that the free ends of the wire are uniformly twistedtogether under the full tension of the heavy spring i. The treadle is then again depressed and the handle again turned to tighten the turns about the hose under control of the light spring r. The handle is turned until the wire breaks, which occurs substantially at the point midway in the length of the twisted wire.

IPC: G01N21/86
Filed: 1969-11-05
Abstract: 1291468 Detecting dangerous gases  DUNLOP CO Ltd 28 Oct 1970 [5 Nov 1969] 54226/69 Heading G1A A device for detecting a dangerous gas comprises a strip of paper, whose optical characteristics are sensitive to the gas and which is passed so as to interrupt two light beams, one light beam being interrupted by a part of the paper which has been exposed to an atmosphere thought to contain the gas while the other beam is interrupted by a part of the paper which has not been so exposed; each light beam being incident on a photo-cell whose outputs are compared to detect the presence or absence of the dangerous gas. In an embodiment, Fig. 2, sensitized paper tape 28 is unwound from a roll 26 by means of a drive roll 27 so as to travel past two separate photo-cells 34 and 35. After the paper has past photo-cell 34 it is exposed to the atmosphere by means of a sampling gate 36 through which some of the atmosphere to be tested is pumped. A light beam from a source 37 is split by a semi-reflective mirror 38 so that one beam passes through exposed paper to photo-cell 35 and the other beam passes through unexposed paper to photo-cell 34. The electrical outputs of the two photo-cells are compared and any difference (indicating the presence of the dangerous gas) is fed via an amplifier to a meter, Fig. 3 (not shown), calibrated in p.p.m. The meter is monitored by a constant current device which actuates an alarm when the concentration exceeds a predetermined level. In another embodiment, Fig. 5, the light from a source is directed along two paths by a bifurcated light guide 40 on to two separate tracks 44, 45 on the sensitized paper. One track 45 being exposed to the atmosphere, the other 44 remaining unexposed. The light paths are directed so that the two beams are reflected off the tracks to be incident on two separate photocells 34 and 35. A further electrical circuit is disclosed similar to the above including a threshold amplifier to actuate the alarm. The detection of Tolylene di-isocynate by a paper treated with a solution of sodium nitrite, 2-Hydroxyl-11 H- benzo a carbazole-3-carboxy-p-aniside (Brenthol GB), ammonium acetate and diethyl phthalate in methanol is exemplified.

Pulses from a generator on a train axle, representing distance travelled, are divided by counting by a factor adjustable to allow for different wheel diameters, then counted, the count being compared with a count of pulses read from a tape track. Equality causes the tape to be driven and verbal information on another track to be communicated audibly to train passengers (or displayed visually, stored or transmitted), a next group of pulses from the first track being read-out to the counter for the next comparison. The tape is stopped after this group has ended in response to detection of the gap after the group. Application to distance travelled by a motor car, the number of revs of a shaft in machinery (to be examined for wear after a certain number of revs), number of articles manufactured, or quantity of liquid dispensed, is also mentioned.

Abstract: 1301918 Digital data storage HONEYWELL INFORMATION SYSTEMS Inc 20 Nov 1970 [18 Dec 1969] 55162/70 Heading G4C An apparatus for and a method of recording data on a magnetic track, e.g. a disc, is disclosed using ternary digits (trits). The track is divided into cells, each cell being divided by four lines T 0 , T 1 , T 2 , T 3  at which magnetic flux transitions may occur. Detecting apparatus registers whether the flux transition at each line is (a) zero, (b) positive or (c) negative, hence each line can represent a ternary digit where ternary 0 is no pulse, ternary + 1 is positive and ternary -1 is negative. There are three rules for reading trits: (i) No four trits will start or end with two consecutive zero's. (ii) The first reversal in a cell must be considered negative. (iii) Successive reversals must alternate in polarity. If these rules are applied the data can be read out from the second and fourth bits, hence if any errors occur in the first and third positions, they can be corrected by comparison with the second and fourth positions, whereas in the prior art all four positions were used for data and errors cannot be corrected. The first and third bits are used here for self clocking.  The apparatus may be used in a digital computer having magnetic or thermoplastic tapes, magnetic discs, drums or thin film cores, punched cards, documents bearing magnetic ink imprints, optically recognizable coded imprints, machine or hand recorded marks.
