Patent GB-259291-A (GB)
Title: Improvements in electrical control systems
IPC: H02P7/282
Filed: 1925-07-06
Abstract: 259,291. Western Electric Co., Ltd., (Western Electric Co., Inc.). July 6, 1925. Regulation, automatic. - The speed or frequency of an electric motor, dynamo, &c. is maintained constant by deriving therefrom an alternating current of a frequency proportional to the speed, and impressing the current, together with another from a source which tends to produce a standard frequency, upon an electron discharge device, the plate current of which controls the speed. In one system described, a shunt-wound direct-current motor 1 is supplied from a source 3, and has an auxiliary field 10 in circuit with the plate of a valve 13. Alternating current of a frequency proportional to the speed of the motor is derived from slip-rings 8, 9 and is impressed by means of a transformer 24 upon three circuits, the cathode heating circuit, the anode circuit, and an oscillating circuit 25, 26 which is tuned slightly above the normal frequency derived from the motor 1. If the speed of the motor increases, the oscillations forced in the circuit 25, 26 approach resonance and the potential variation on the grid of the valve 13 is increased with consequent increase in anode circuit, strengthening of the field 10 and slowing down of the motor. Various modifications are disclosed, the alternating current for the oscillatorv circuit mav be derived from an alternator on the motor shaft, and the oscillating circuit may be replaced by a tuning-fork.

Patent GB-1431163-A (GB)
Title: Computer  memory system
IPC: G06F12/02
Filed: 1974-04-23
Abstract: 1431163 Memory systems HONEYWELL INFORMATION SYSTEMS Inc 23 April 1974 [23 April 1973] 17664/74 Heading G4A An unused area of memory (bounded by regions containing stored data to be preserved) is divided into blocks of at least two sizes by forming first the maximum number of contiguous blocks of the largest size and then repeating this process for successively smaller block sizes. As described division is into 32 word, 16 word and 8 word blocks. The memory is divided into sectors between which and in which unused areas may exist. A "free memory-area" table is stored in the memory, listing starting and ending addresses of each gap and terminating in a sentinel word. The memory also includes software "initialization" routines for dividing the gaps. In a first phase (routine of Fig. 8, not shown) the table is accessed to get the start and end addresses of the first free areas which are saved in memory location. If the end address does not follow the start address for the initialization routine the area is divided into blocks (routine of Fig. 9, not shown) and the table then accessed for the next free area. This process is repeated until the terminal sentinel word is accessed. A check is next made to see if the minimum storage requirements are met (routine of Fig. 11, not shown) and if they are not the free area of memory between the table and the declared end of memory is also divided (routine of Fig. 12, not shown). Divide routine (Fig. 10, not shown).-From the start address N for the free area to be divided, a start address J for the first block of largest size S is derived by letting and checking that J+S is less than the end address M of the free area. This process is then repeated by increasing the address J by the size S until J + S#M when the next smaller block size is processed. A pool parameter table of the information derived i.e. the addresses of the various block sizes, the number of blocks available &c. In a second phase (routine of Fig. 13, not shown) after all the free area has been divided, a fragment routine (Fig. 14, not shown) is affected in which the number of largest block sizes (held in the pool parameter table) is first examined to see if it exceeds the required number of blocks for an operation. If it does the next block size is examined. If a block is not large enough, e.g. if the number of 16 word blocks is insufficient a routine to divide one of the 32 word blocks (routine of Fig. 15, not shown) is effected (if there is an excess of the blocks), incrementing of the number of 16 word blocks and decrementing of the number of 32 word blocks in the pool parameter table being carried out.

Title: Improvements in or relating to arrangements for the selective protection of electricnetworks
IPC: H02H3/02
Filed: 1958-06-03
Abstract: 848,510. Power supply protection systems. SIEMENS-SCHUCKERTWERKE A.G. June 3, 1958 [June 15, 1957], No. 17726/58. Class 38 (4). Variable resistors inserted in an electric power supply system in the case of a short-circuit fault are retained selectively by voltagedetecting devices so as to isolate the faulty section. Fig. 2 shows a supply system feeding power to a point F from a bus-bar 4 via a transformer 5 and variable resistors 6, 7. The normal resistance of the members 6, 7 is substantially zero but in the event of a short-circuit at F the current increase causes the members 6, 7 to increase rapidly in value. When the resistance values of the members 6, 7 are about half-way to maximum, a slider on each member opens switches which allow the voltages at points a, b, c, d to be fed to voltage-sensitive devices 13b, 13a, 10b, 10a via low-pass filters 9b, 9a, 8b, 8a. Each voltagesensitive device may be in the form of a solenoid which when energized retracts a locking member which allows the variable resistor to return to zero resistance. Thus a low voltage at a causes the variable resistor 7 to be locked in its maximum resistance position. A delay device may be incorporated to allow the selected resistor to be operated more than once before being locked.

Title: Improvements in or relating to thermostatic valve mechanism
IPC: G05D23/12
Filed: 1940-12-16
Abstract: 547,220. Fluid-pressure servomotor-control systems. BRITISH THERMOSTAT CO., Ltd., and SHERLOCK, J. E. Dec. 16, 1940, No. 17730. [Class 135] A device for controlling the flow of heating or cooling medium particularly applicable to the cooling system of an internal combustion engine comprises a main valve element adapted to be operated by the pressure of the fluid circulating in the system under the control of thermallyactuated auxiliary valve device. In the arrangement shown in Fig. 1 a main valve casing a is connected at g to the outlet from the cooling jacket h of an engine and at band d to the inlet and outlet respectively of a radiator c. A pump e draws liquid from the radiator and returns it to the cooling jacket and also supplies pressure fluid through a pipe z to a nozzle t. Fluid from the nozzle t passes into a nozzle u unless interrupted by a baffle v and builds up a pressure beneath an actuating piston working in cylinder supported from the casing a by radial arms or a ported web q. The piston k is coupled to a lift valve i and a tubular lift valve o adapted to co-operate with seats m, n on opposite sides of partition m<SP>1</SP>. When the pressure in the cylinder is low the radiator c is short circuited through the port. As the pressure rises the valve i opens and the valve o closes to prevent more and more of the liquid to circulate through the radiator. In a modification the valve i is replaced by a double beat valve and the valve o by a simple lift valve. In the first form the valve acts to maintain the pressure at the radiator inlet at a valve corresponding to the controlling temperature while in the second form the pressure at the radiator outlet is maintained at the required value. Any alternative form of auxiliary valve may replace the baffle and nozzles and a light spring may load the valve i towards its seat.

Abstract: 908,873. Laminates. BRITISH CELANESE Ltd. May 25, 1960 [May 26, 1959], No. 17856/59. Class 140. [Also in Group XV] Sheet material comprises a layer of crumbs of thermoplastic material, a sheet of thermoplastic material in contact therewith containing particulate light-reflective material, and a transparent thermoplastic sheet in contact either with the layer of crumbs or with the sheet containing the light-reflective material, the assembly being bonded together by the application of heat and pressure. The sheets and crumbs may all be of secondary cellulose acetate (i.e. partially hydrolysed cellulose acetate soluble in acetone), or one or both of the sheets may be of cellulose triacetate, or the thermoplastic material may be polystyrene. The crumbs may be colourless or coloured, and may pass through a 10-mesh but not through an 18-mesh sieve. The transparent sheet may be colourless or coloured, and the particulate light-reflective material may be pearl essence or metal powder. The sheet of thermoplastic material may be treated with a softening agent before application of the crumbs. In pressing, a resilient sheet may be placed between the light-reflective sheet and the press, and may be a thermoplastic sheet which may be coloured and which becomes bonded to the assembly or may be bonded to the lightreflective sheet before pressing of the assembly. Alternatively, it may be separated from the light-reflective sheet by a film of non-adhesive materiel, e.g. polythene or regenerated cellulose. The layer of crumbs may be applied to the non- adhesive film, and the light-reflective film and the transparent film applied thereover with applications of solvent or softening agent to assist bonding. In Example 1, a film of secondary cellulose acetate containing diethyl phthalate and pearl essence is bonded by heat and pressure to a transparent secondary cellulose acetate sheet containing dimethyl phthalate and triphenyl phosphate. The pearl side of the laminate is coated with a mixture of diacetone alcohol, the monomethyl ether of ethylene glycol, and dimethyl phthalate, colourless crumbs of plasticized cellulose acetate are applied thereto, a transparent coloured cellulose acetate film is applied thereover, and the assembly is bonded together at 70‹ C. under pressure. The first two sheets may be placed separately in the assembly and bonded in the final operation. In Example 2, the coloured and transparent films are transposed, and the crumbs separated from the latter by a polythene film, and the polythene and transparent films are stripped off after hot-pressing.
