Patent GB-514005-A (GB)
Title: Improvements in and relating to electric motor control systems
IPC: H02P5/685
Filed: 1938-04-25
Abstract: 514,005. Master control of D.C. motors; controllers. BRITISH THOMSON-HOUSTON CO., Ltd. April 25, 1938, No. 12358. Convention date, April 24, 1937. [Class 38 (iii)] A controller as described in Specification 513,114 has a relay responsive to the speed of the motors. Movement of the master controller from accelerating to coasting position latches the relay in a position corresponding to the speed of the motors at the time of movement, and preselects the required braking resistance. Further movement of the master control to the braking position commences the braking operation described in Specification 513,114 at the point preselected by the latched relay. Cam disc 94 is supported on the rotatable shaft (as shown) of an operating element 99 which comprises a magnetizable stator having opposed pole pieces between which is mounted a magnetizable rotor bearing a winding energized in accordance with the current flowing through two of the motor fields. Cam disc 94 is also provided with toothed segment 105 arranged to be engaged by the latch 106 which is biased by a spring 107 and magnetizable armature 93 is provided with an energizing winding 108 arranged to operate the armature in a counterclockwise direction about its pivot from the position shown. Whenever the winding 108 is energized a pin 109 carried by the armature 93 operates the latch 106 so as to release the cam disc 94 for movement by the operating element 99 in accordance with the speed of the motors, and as soon as the winding 108, is de-energized, the cam disc 94 is latched in the position it then occupies, one of the cam surfaces 95, 96, 97, then serving to limit the clockwise movement of the armature 93 so as to determine the amount of separation of the contacts 87 and 88 which control the stop coil of the resistance excluding device described in Specification 513,114. Whenever the contacts 87 and 88 are separated the cam switch associated with resistance including means, operates in a direction to move the contact 87 by means of cam 86 toward contact 88 until the contacts are engaged whereupon the resistance excluding operating device is stopped by its associated stop coil. Exclusion of braking resistance in the main circuit of the motors is then carried out as described in Specification 513,114 when the master controlled is moved to its braking position. Specifications 456,123 and 514,263 also are referred to.

Title: Stabilizing circuit for electrical regulator system
IPC: H02P9/04
Filed: 1955-04-29
Abstract: 789,995. Automatic control systems for dynamo-electric machines. BENDIX AVIATION CORPORATION. April 29, 1955 [May 27, 1954], No. 12403/55. Class 38 (4). In a system for automatically controlling voltage and/or frequency of a dynamo-electric machine, the energization of a field winding of the machine is controlled by a carbon pile regulator, one winding of which is energized in dependence on the voltage or frequency and another winding of which is energized through a rectifier in dependence on voltage in the field circuit. As shown, a shunt motor 1 supplied with D.C. through leads 4, 5 drives an alternator 2 supplying A.C. to leads 21, 22. Output voltage is automatically maintained at a desired value by connecting in series with alternator field winding 19 a carbon pile regulator 35, main winding 41 of which is energized through a rectifier 44 from output leads 21, 22. Output frequency is automatically maintained at a desired value by connecting in series with motor field winding 6 a carbon pile regulator 9, main winding 15 of which is energized from output leads 21, 22 through a rectifier 16 in series with a tuned circuit 25 resonant at a frequency slightly removed from that desired. To prevent hunting, each carbon pile regulator has an auxiliary winding (27, 48), energized through a rectifier (29, 50) by the voltage across the field winding which it controls, so that reverse voltage induced in the field winding upon sudden reduction of field excitation is effective to energize the auxiliary regulator winding which opposes the main winding to stabilize the regulator.

Title: Improvements relating to methods of and machines for duplicating
Inventor: FORD RONALD MAX
IPC: B41L11/00
Filed: 1956-04-24
Abstract: 860,224. Printing surfaces. FORD Ltd., F. R. April 23, 1957 [April 24, 1956], No. 12438/56. Class 100(2) In a rotary duplicating machine, separate sheets can be secured to the master cylinder so as to overlap axially to a variable extent, there being provided on the cylinder sheet securing means which prevent circumferential displacement of the sheets during operation of the machine, while permitting axial displacement of at least one of the sheets by direct manual application of an axial displacement force, at least in one position of rotation of the master cylinder. The master sheet 20, Fig. 3, is clamped by a pivoted member 16 which in its closed position defines a slot comprising a radial limb 22 and a circumferential limb 18. The sheet 20 may have a close fit in the limb 22, whereas in the limb 18 two pads are inserted one at each end between the member 16 and the bottom wall of the slot so as to allow a clearance of 0À004- 0À012 inches in excess of the sheet width, whereby the sheet can be moved axially by direct manual effort while being restrained circumferentially. The member 16 is opened for sheet removal and closed by a toggle mechanism 38, 39, 40, Fig. 1, similar to that described in Specification 657,765. An overlying sheet 19, e.g. a masking sheet, is held in a similar slot by a member 15, but in this case the pads may be omitted so that the sheet is firmly clamped. The member 15 and its slot may be reversed so that the tails of both members 15, 16 project in the leading direction. The member 15 is secured to a rocker member 25 so as to be held in closed position by a spring 27. A plate 33 fixed on a pin 30 rotatable in a bearing bush on the machine side-frame is normally held out of the path of the member 25 by a spring attached to a fixed pin 35, but can be moved into the path of the member 25 by a finger piece on the pin 30, so that in a particular position of the cylinder 10 the member 15 is opened to allow either axial movement or removal of the sheet 19. The sheet 19 may be sub-divided into a masking sheet 41, Fig. 5, and a master sheet 42 bearing a heading or other constant data. The adjacent edges 44, 45 of the sheets 41, 42 are spaced apart by a distance equal to or slightly greater than the axial width of the zones on the main master sheet 20 from which matter is required to be reproduced selectively. The sheet 41 is provided with an aperture 43, the edges 46, 47 of which are slightly further apart than the edges 44, 45, through which the operator's finger can move the sheet 20 axially by amounts approximately equal to the abovementioned zones. A similar aperture may be provided in the sheet 42. A plurality of masking sheets 41 may be provided having apertures of different width. Specification 638,902 also is referred to.

Patent GB-802128-A (GB)
Title: Method of adsorbing glycols from liquid hydrocarbons
IPC: C07C7/12
Filed: 1956-04-24
Abstract: Liquid cyclic hydrocarbons containing not more than 5 per cent by weight of glycols are separated therefrom by selective adsorption of the glycols on natural or regenerated cellulose. Typical hydrocarbons are tetra- or deca-hydronaphthalene, diphenyl and a - or b -methyl naphthalene which may contain ethylene glycol.  The cellulose preferably has a large surface area and may be in the form of filter paper rings, balls, cellulose wadding, voluminous tablets or viscose sponge.  Viscose sponge is preferably dried to a water content of less than 4 per cent by weight, e.g. by treating with a 5-10 per cent by weight aqueous solution of glycol or glycerine to prevent hardening, wringing out and drying in air spread out on frames for about two days.  The adsorped glycols may be recovered by squeezing out, extracting with water or methanol or by distillation under normal or reduced pressure.  A continuous process is illustrated employing an endless belt of viscose sponge from which the glycols are recovered by passing the belt between rollers.  The examples illustrate the separation of ethylene glycol from tetrahydronaphthalene.

Title: Gas Blast Circuit Breaker.
IPC: H01H33/32
Filed: 1968-03-15
Abstract: 1,158,248. Gas-blast switches. ETABLISSEMENTS MERLIN & GERIN S.A. 15 March, 1968 [23 March, 1967], No. 12623/68. Heading H1N. In gas-blast circuit breakers in which one or more arc extinguishing chambers are maintained under pressure both in the open and closed positions of the contacts and in which the open position is maintained by pressure in the chambers, a safety device is incorporated to cause closure and locking of all the contacts in the event of a fall in pressure in the chamber at a value higher than that at which the contacts would otherwise close. The example of Fig. 1 is applied to a pneumatically controlled system in which pressure applied at 26, or 28 on piston 22 of a control valve 10, opens or closes ports 16, 20 to vent or apply pressure through line 12 to open or close the contacts. A pressure controlled relay valve 40 moves to the position shown under a fall in pressure in the gas reservoir 30, whereby a piston 34 at one end of the control valve 10 normally vented to atmosphere at 60 is placed under pressure to move and hold the valve 10 to the left (as shown) whereby the contacts are maintained closed and cannot be opened by control pressure on piston 22. In a modification in which the contacts are controlled through hydraulic lines 72, 74, Fig. 2, to which pressure is applied through electromagnetic control valves 88, 88<SP>1</SP> and pressure transmitters 76, 76<SP>1</SP> a pneumatic actuator 132 is arranged to move the electromagnetic valve 88 to cause automatic closure of the contacts when the pressure in reservoir 70 falls. For this purpose, relay valve 120a normally venting the actuator 132 to atmosphere through port 129 when held up by pressure in line 124 connected to chamber 70 falls to the position (shown) at low pressure. Any pressure in line 110, occurring only when the contacts are opened, is then effective through line 28 to cause actuator 132 to automatically close the contacts. If the contacts are already closed, actuation of electromagnetic valve 88<SP>1</SP> to trip the contacts results also in pressure being applied to actuator 132 of valve 88 to maintain closure of the contacts. The arrangement may be applied to circuit breakers in which a series of contacts open sequentially when initially triggered by the actuators. The pressure sensitive valve 120 g. may also be replaced by a pressure switch which cause actuation of the solenoid valve 88.
