Title: Magnetic system for information storage
IPC: G11C11/06
Filed: 1955-05-20
Abstract: 773,457. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 20, 1955 [May 25, 1954], No. 14583/55. Class 106 (1). Apparatus for storing and transferring data comprises a plurality of magnetic core registers (Reg. 1-4., Fig. 1), shift means coupled to said magnetic core registers for shifting stored data therefrom, writing means coupled to said magnetic core registers, and control means coupled to said writing means and said shifting means for preventing simultaneous storing and shifting in the same magnetic core register whereby data may be stored in a selected register and other data may be transferred simultaneously from the remaining registers. As described, data in parallel form from a source 51, Fig. 4, enters a selected one of four registers, Reg. 1-Reg. 4, Fig. 1, the particular register being determined by a two-digit address, and is immediately dynamicised by the application of four shift pulses to the appropriate shift lead 22-25, the entered data thus emerging in serial form on one of channels 1-4. Normally, each of flip-flops 100-103, Fig. 4, maintains its upper lead more positive, and each of gates 90-93 is prepared to pass a write pulse providing it is opened by the output from a decoding matrix. Each data-word and its address is staticised on six flip-flops 62-65, 175, 176 so arranged that upon the application of a write pulse to the associated gates the data is applied to the four-vertical leads 14-17 of the storage matrix and a selected one of the horizontal leads is energized. If the selected register is Reg. 1 then the pulse applied to the horizontal lead 18 from gate 90 also changes over flip-flop 100 which opens a gate 104 allowing four shift pulses, counted by a counter 115, to be applied to register 1 before it is reset. Each shift pulse " zeroizes " each core, and causes its previous state to be temporarily stored on a condenser type transfer network. Thus while the contents of register 1 are being shifted on to channel 1, other data can be entered into the other registers. Ideally, the addresses of the arriving data would pass sequentially from the first to the last register, the last register being followed by the first, or, alternatively, the arrangement could be used for sorting data arriving in random order. A tetrode connected pentode is described as an infinite impedance constant current source for use as a driver, constant current sources being necessary to prevent interference between two or more registers. Specification 768,183 is referred to.

Abstract: 928,173. Rotary sprayers. BUCKNER MANUFACTURING CO. Inc. April 24, 1961, No. 14778/61. Class 69 (3). A step-by-step rotary sprinkler includes a friction brake applicable over certain sectors of its travel so that the relative saturation of different areas within the distribution pattern is controllable. A stationary housing 15 attached to a water supply conduit 10 embraces a rotatably mounted tube 25 secured to a rotary head 35 having nozzles 39, 40 at the end of arms 37, 38. A step-by-step drive of the head is effected by a bar 47, with a counterweight 49, rigidly secured to a sleeve 46 rotatably mounted about a post 45 upstanding from the head. The bar is urged by a spring 51 against a plate 50 secured to the head so that in operation, the water jet from the nozzle 39 strikes a deflecting member 48 on the bar and turns the bar away from the jet and against the action of the spring ; on its return, the bar strikes the plate 50 and turns the head one step. The tube 25 is flanged at its base at 26, and a spring 72 urges the tube and rotary head upwardly whereby the flange 26 compresses washers 28, 29 against the housing 15. The friction brake includes a stationary collar 55 adjustably mounted on the housing 15 and provided with opposed brake segments 60 with brake surfaces 61 against which opposed friction pads 89, e.g. of rubber, in a rotary bracket 76, bear during operation of the sprinkler. The bracket 76 is journalled on the collar and is driven by a finger 105 secured to the head 35. The friction pads are carried in opposed arms on the bracket and are mounted in tubular holders 86 urged inwardly towards the brake surfaces by springs 99. Bolts provide adjustment of the compression of the springs. When a number of such sprayers are aligned as shown in Fig. 5, the braking surfaces 61 are so located that they are not brought into play during the spraying of overlapping areas, but are contacted by the friction pads at other times.

Title: Improvements in or relating to servo systems of the closed-loop type
IPC: G05D3/14
Filed: 1948-06-02
Abstract: 658,192. Automatic control systems. GENERAL ELECTRIC CO., Ltd., and GILCHRIST, D. C. June 2, 1948, No. 14893. Drawings to Specification. [Class 38 (iv)] [Also in Group XXXVIII] In a servo system of the closed loop type, two or more electric amplifier stages are provided with a positive feed-back path across one or some stages, the amplification round the positive feed-back loop being unity and the phase shift round the positive feed-back loop being such that the servo system is at least as stable as it would be without the positive feed-back path. The stability of the system is increased when the phase shift round the positive feed-back loop is about 180 to 270 degrees at the frequency at which in the absence of this loop the tendency to hunt is greatest. The following systems are described, the resistance-inductance type of phase shift network being two-stage and having mutual inductance between the inductances as in Specification 658,223, [Group XL (b)] : (a) a system for maintaining constant the output current of a D.C. generator in which the voltage across a resistance in series with the output of the generator energizes a field winding of a first D.C. exciter machine supplying the field winding of a second D.C. exciter machine which, in turn, supplies the field winding of the generator. Energization of an auxiliary field winding of the first exciter machine through a resistance-inductance phase-shift network from the voltage across a resistance in series with the output of the first exciter machine, provides the positive feed-back ; (b) a system for maintaining constant the output voltage of an alternator in which the voltage from a potentiometer across the alternator terminals controls, through a rectifier and a two-stage magnetic amplifier, the energization of the field winding of a D.C. exciter machine supplying the alternator field. Positive feed-back from the output to the input of the magnetic amplifier is provided through a resistance-inductance phase-shift network. In addition, negative feed-back from a potentiometer across the exciter machine output terminals to the input of the magnetic amplifier is provided through a resistance-condenser network to give a transient response ; (c) a system for maintaining constant the output voltage of a D.C. generator in which the voltage from a potentiometer across the generator terminals controls, through a two-stage thermionic amplifier and a second thermionic or dynamo-electric machine amplifier, the energization of the field winding of a D.C. exciter machine supplying the generator field. Positive feed-back from the output to the input of the first-mentioned thermionic amplifier is provided through a three-stage resistancecapacity phase-shift network. An additional stabilizing resistance-capacity network is included in the input to the first mentioned thermionic amplifier.

The limit speed for each section is the lowest of the section speed determined by the track data, the travel speed determined by track signals set from the control station and an operational speed determined by a central monitoring office controlling a number of zones, and the travel data is determined from the stored limit speed and from braking data of the vehicle obtained from a vehicle data store. The travel data for transmission to a vehicle in a section is obtained from the associated store and the transmission includes the number of the track section occupied, the desired travel direction, the number of a required braking curve, the nominal braking distance, the destination distance i.e. the distance to a required change in speed and the value of the speed at the destination. This information is used on the train as described in Specification 1,117,123. In response to receipt of this transmission the train answers with data including its position on the track, braking data, actual speed and train length.
