Title: Data transmission system

Filed: 1972-10-18
Abstract: 1367821 Data transmission; coding INTERNATIONAL BUSINESS MACHINES CORP 18 Oct 1972 [29 Nov 1971] 47953/72 Heading H4P A message is encoded into two simultaneous related pulse sequences which are transmitted and at the receiver turned into two more sequences, the addition of which reproduces the message. The message, assumed to be two pulses f 1 , f 2  separated by a time T and derived by sampling an analogue signal (fct) Fig. 1, not shown), is applied to two delay lines 26, 28. These may be piezo electric substrates with interdigital transducer electrodes (Fig. 6, not shown), and have tappings separated by the said time T which supply unity multipliers 38, 40, 44, 46 one of which 46 produces inversion. The outputs of each pair of multipliers are added at 42, 49 and because the pulse f 1  reaches 40 as f 2  reaches 38, they combine so that a three pulse signal is produced in the transmission line with the form f 2 , f 1 +f 2 , f 1 . Adder 49 produces a different combination due to the inversion. At the receiver, delay lines 48, 58 reverse the process, the multiplier 64, 66 having their polarities interchanged relative to 44, 46 at the transmitter (the reversal of 54, 56 is not obvious). The result of adding at 72 the results of the decoding process produces a signal similar to, but four times larger than the message input f 1 , f 2 . Hence the signal to noise ratio is much improved. The two transmission channels may be multiplexed to a single line (Fig. 3A, 3B, not shown). Two or more messages (F, H, Fig. 4A, 4B, not shown) may be combined by respective coders and decoders into the same pair of transmission channels as Figs. 2A, 2B or the same single multiplex channel of Figs. 3A and 3B. The improvement in message signal amplitude, relative to noise, is shown to be proportional to the product of the number of tappings on each delay (m) and the number of channels or effective (if multiplexed) channels (n). An embodiment using four tappings (m=4), four channels (n=4) multiplexed to one line, and four input messages, is described (Figs. 5A, 5B, not shown), and an embodiment using double transformations at the coding stage and double inverse transformation at the receiver decoder stage (Figs. 7A, 7B, not shown) is said to give a message signal increase factor of (m.n)<SP>2</SP>.

A hydrodynamic brake comprises: a pair of coaxial contrarotating rotors; a casing surrounding the rotors and providing a circulatory path for brake fluid at right angles to the direction of rotation of the rotors; a fan coupled to the drive for one rotor to provide a flow of cooling air; and means for regulating the flow of brake fluid to variably control braking. In one embodiment, Fig. 1, contrarotating rotors 1, 2 comprise cylinders having axially movable pistons 16, 17 which carry co-operating blades 4, 5, 6, 7. To apply the brake, hydraulic fluid is pumped into the cylinders to move the two pistons towards each other against the pressure of springs 20, 21. The pressure fluid circulating round the rotor blades 4, 5, 6, 7 and the deflector blades 9 are cooled by fans 12, 13 which blow air through an outer channel 11. In an alternative arrangement, Fig. 2, the stator casing and rotor blades 55, 56, 57 define a torroidal passage 60 of annular cross-section. The degree of braking is controlled by a tubular sliding member 58 which is inserted into the chamber 60 to throttle the circulation of fluid. When the member 58 completely closes the chamber 60 the brake is inoperative. Cooling is effected by fan 75 which blows air over vanes 76.

Abstract: 1284875 Digit storage circuits PLESSEY CO Ltd 26 Sept 1969 [10 Oct 1968] 48157/68 Heading H3T [Also in Division G4] A temporary store comprises a Zener diode or like device and an ordinary diode in series backto-back, the diodes being separate or basecollector and base emitter diodes of a vertical or lateral transistor. Current in the reverse direction of the Zener diode stores charge in the region between the diodes and this will remain when the current is interrupted. The presence of the charge may be sensed by applying a voltage in the opposite sense to the two diodes so that current flows in the reverse direction through the ordinary diode until the charge is removed. An output gate associated with the sensing means preferably remains closed during the initial portion of the current pulse, to exclude noise. Such stores may be arranged at the crosspoints of a co-ordinate storage matrix, write in being effected by half-amplitude pulses on each of the corresponding X and Y lines, the total amplitude being sufficient to exceed the Zener and forward thresholds of the respective diodes. Read-out is similarly effected, except that the total amplitude need exceed only the forward thresholds. Regeneration and the use in word organized stores are referred to.

A high molecular weight polymer of formaldehyde is prepared by polymerizing formaldehyde in a solution or dispersion containing carbon dioxide. The carbon dioxide may be the sole solvent or dispersion medium or there may also be present an organic solvent of boiling point up to 40 C., e.g. ethane, butane, propane, t.-pentane, dimethyl ether, diethyl ether and their mixtures. The polymerization may take place in the presence or absence of a catalyst which may be anionic or cationic triethylaluminium, trin - butylamine, triphenylphosphine, calcium stearate trimethylamine, tin tetrachloride and boron trifluoride being amongst those listed. Alternatively the polymerization may be promoted by irradiating the reactants with X-ray or ionizing radiation at -78 to +20 C. An acylated polymer may be prepared by polymerizing the formaldehyde in carbon dioxide solvent in the presence of a carboxylic acid anhydride and after polymerization heating the whole reaction system, or the residue after returning the reaction system to atmospheric pressure and recovering carbon dioxide and unreacted formaldehyde, to above 100 C. to complete the acylation. The carboxylic acid may be present in an amount up to 50 mol per cent of the formaldehyde acetic, propionic, benzoic, stearic and caproic anhydrides, being specified as well as those of polybasic acids. The formaldehyde starting material may be prepared by concentrating a neutral aqueous solution of formaldehyde or there may be used a mixture of formaldehyde and carbon dioxide obtained by liquefying the gaseous product from thermally decomposing a low-molecular weight formaldehyde polymer in a stream of carbon dioxide.
