Title: Improvements in binary digital parallel adders
IPC: G06F7/503
Filed: 1957-04-10
Abstract: 833,781. Binary parallel adders. SPERRY RAND CORPORATION. April 10, 1957 [April 12, 1956], No. 11670/57. Class 106 (1). [Also in Group XL (c)] In a binary parallel adder, each stage includes transistor gating means for propagating carries. In the binary adder shown in Fig. 1, the addend is applied via terminals 10, 11 ... 12 and delays D1, D2 ... Dn to half-adder accumulator circuits (called half adders ") HA-1, HA-2 ... HA-n which each provide sum outputs 0 and 1 and carry output C. When a new addend is entered, carries are stored on " flip-flops " FF-1, FF-2 ... FF-n (cleared by pulses on line 17) in the next higher stages; each carry allows a subsequent carry gate pulse on line 14 to pass through a corresponding gate G1a, G16 ... G1n to the associated accumulator inputs, and if any accumulator circuit registers 1, an associated gate G2a, G2b ... G2n is opened to allow the carry pulse to be propagated also along line 18 to higher stages. According to the invention, gates G2a &c. comprise transistors such as NPN junction type transistors 20, 21, 22, Fig. 2. Also, the carry storage flip-flops may be replaced by transistors such as 30, Fig. 3A, arranged to be overdriven by a carry input pulse at its base so as to produce, owing to a " charge storage " effect, an extended output pulse which continues for sufficient time to gate the carry pulse on 14. Alternative gates (G2) are described and shown employing PNP type transistors and/or different electrode connections. The PNP transistors 51, 52, 53, Fig. 7, in carry propagation line 50 are connected by pulse-inverting transformers 54, 55, from which the connections to the accumulator inputs are also taken. The delays may comprise saturable inductors. In another gating arrangement (Fig. 8, not shown), NPN and PNP transistors are used alternately.

Filed: 1967-03-14
Abstract: 1,137,038. Vehicle detection systems. RADIO CORPORATION OF AMERICA. 14 March, 1967 [29 March, 1966], No. 12032/67. Heading G4Q. In a vehicle detector of the type in which slow condition changes in the detection zone would tend to cause a voltage rise in the circuit and initiate a false indication, means are provided which only permit the build up to occur in response to rapid condition changes, due to entry of a vehicle into the zone. As described, the time constant of the C.R. circuit 24, 26 is such that slow negative changes in voltage at A do not cause diode 30 to cut off and relays 38, 40 remain energized. A rapid negative change, due to a vehicle entering loop 20, cuts off diode 30 and the resulting change in input to amplifier 34 releases relays 38, 40 to isolate the capacitor and actuate an indicator. Each vehicle entering the detection zone adds to the charge on capacitor 24, and each one leaving subtracts from it, so that the indication is only cancelled when the last vehicle leaves.

[Classes 68 (ii) and 85] [Also in Group X] A retaining wall construction for supporting earth, tunnel linings and underground enclosures, comprises a number of cantilever units 11 clipped together side by side, each formed of base and wall members 14, 15 with the wall members secured by clip strips 13 engaging hook flanges 28 and - the base members by spaced clips 30 which engage similar hook flanges. A sub - surface concrete anchor wall 12 is formed near the foot of the earth bank and the piercing end 17 of the base members is placed on it, the members being driven into the bank by hydraulic jack-means 60. A swivel heel anchor 35 at ends 17 and the abutment of the clip strips 13 against the inner face 19 of the concrete wall when driven down through notches 38 in the hook flanges of the base members provide anchorage against horizontal slipping. The jack-means 60 include three parallel rails which with their ends 66 hooked over the inner end of the wall 12 provide two successive tracks for a jack placed between rear and front buck plates respectively pinned to the rail flanges and placed behind the outer end 18 of a base member 14. Two units thus driven into position are then clipped together. Two opposite wall structures may be united by roof beams to form the lining of a tunnel.

Title: Memory system

Filed: 1959-04-10
Abstract: 885,944. Circuits employing bi-stable magnetic elements. SYLVANIA ELECTRIC PRODUCTS Inc. April 10, 1959 [April 10, 1958], No. 12288/59. Class 40 (9). [Also in Group XIX] A storage matrix of magnetic cores has a strobe core or a matrix of such cores controlling the output of the storage matrix to suppress spurious output noise. As shown, the matrix consists of 40 planes 11, each accommodating 64 x 64 magnetic cores. 40-bit words are stored, one bit in each plane. The x and y lines are driven from 8 x 8 switching matrices 14 controlled from the memory address register. Signals - on the sense line 13 of a plane are sent to a sense amplifier 28 and are then gated under the control of the strobe core 12a to a flipflop of the one-word output register 31. The strobe core 12a is in the common connection to earth of the x and y lines, thus signals applied to any core of the storage matrix will also be applied to the strobe core. The spurious output noise due to half reading unselected cores received on a sense winding 13 slightly precedes the required output from the selected core and is eliminated by applying the output of the strobe core suitably amplified and delayed to one input of each AND gate 29, the other input being from an amplifier 28 receiving the sense winding signals. Thus only the output of the selected core is gated to the flip-flop register 31. Instead of a single strobe core, a matrix of such cores may be used each core connecting 8 z- and 8 y-lines to earth.

Title: Improvements in or relating to reversing mechanism
Filed: 1925-05-15
Abstract: 256,343. Dawson, Sir A. T. and Buckham, Sir G. T. May 15, 1925. Reversing gear - ing comprises unloaded gears slidable into mesh, the drive being then imposed through a friction clutch. Further frictional means may spin the loose wheel prior to remeshing to facilitate engagement. Gears C<1> C<2> splined on a sleeve E, Fig. 1, may drive a wheel B<1> directly on a wheel B<2> indirectly through an idler so that a shaft B is driven in either direction. The sleeve E is loose on a fixed shaft F and carries a disc E<1> passing between two plate clutches K, L inside and adapted to make driving connection with a drum D geared to a driving-shaft A. When the double gear C<1>, C<2> is moved to the right by a lever C<3>, after meshing it strikes a shoulder E<2> on the sleeve so as to carry the sleeve to the right. The disc E' then entrains the clutch K so that driving takes place. On moving the double gear to the left, a shoulder E<3> is struck and the clutch L is brought in. In a modification, the drum is on the sleeve and the disc drives. In the arrangement shown in Fig. 4, there is a single clutch K within the drum D on the driving-shaft A. When the double gear C<1>, C<2> is moved to the left, the shoulder E<2> is engaged and the whole clutch is brought in by a second shoulder e. When the movement is to the right, the same whole clutch is entrained by shoulders E<3> and e<1>. This clutch may be held in light engagement at all times to spin the loose pair C<1>, C<2> prior to engagement. Or the loose pin may be constantly driven as shown through a friction train a, a<1>, a<2>, a<3> to facilitate engagement. In another arrangement the additional light drive is obtained by a friction disc pressed upon by a spring washer.
