Patent GB-705733-A (GB)
Title: Improvements in or relating to regulating devices for electric generators
IPC: H02P9/04
Filed: 1951-12-24
Abstract: 705,733. Automatic control systems. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Dec. 24, 1951 (Dec. 22, 1950], No. 30139/51. Class 38 (4) In an automatic control system for a turbine driven generator, the turbine being regulated by a primary speed regulator, the datum setting of which is adjustable by a reversible servomotor, the servomotor is energized for periods proportional to the magnitude of the deviations of an unspecified parameter of the generator by superimposing on the main control signal a sawtooth voltage of opposing polarity. A polarized relay 2, Fig. 1, is energized by some device 1 which provides a D.C. current, the magnitude and polarity of which are proportional to the magnitude and direction of the deviations from normal of any desired parameter of the electric generator (not shown). The relay 2 energizes, via a normally closed contact 20, either relay 5 or relay 6, the contacts 11 or 16 of which control a reversible servomotor (not shown) which adjusts the primary speed regulator to correct the deviation. Contacts 8 or 13 short circuit the normally open contact 21. and energize a motor 18 which rotates the slider of a potentiometer 26 to produce a sawtooth voltage of constant frequency which is applied via a resistor 29 to the operating coil of the relay 2. The polarity of the sawtooth voltage is determined by the reversing contacts 9, 10 or 14, 15 of the relays 5 or 6, and is such as to oppose the control current in the coil of the relay thus causing the relay to open early. As the motor 18 revolves, cam 23 opens the contacts 20, but these are bridged by contacts 7 or 12 as long as the relay 5 or 6 is energized by the relay 2, and contact 21, though opened and closed by cam 24, remains bridged by contacts 8 or 13 so that the motor 18 continues to run. When relay 2 opens, relay 5 or 6 opens to de-energize the servomotor, but the motor 18 continues to be energized via contact 21 until the cams 23, 24 reach their normal position. Until this is reached contact 20 is open so that if the sawtooth voltage alone should cause the relay 2 to reverse its contacts, neither relay 5 or 6 will respond. In another embodiment, Fig. 2, the total output of a power station, having three generators, and the load sharing between individual generators is effected by three polarized. relays 55, 63, 71, each having two opposing windings one of which is energized as before by the unspecified devices 51, 52, 53 (one for each generator) and the sawtooth generators 62, 70, 78, whilst the second winding is energized by a current which is the algebraic sum of the currents generated by the devices 51, 52, 53, 54. Device 54 provides an output proportional to the difference between the actual total output of the station and a predetermined output. These second windings are each shunted by a variable resistor 79, 80, 81 so the load may be variously apportioned between the generators.

Title: Improvements in apparatus for feeding type metal to composing machines
IPC: B41B11/82
Filed: 1930-10-08
Abstract: 356,526. Type-making machines. PERRINJAQUET, L., 6, Militõrstrasse, Berne, Switzerland. Oct. 8, 1930, No. 30141. [Class 100 (iii).] Metal-pots.-In a device for automatically feeding the metal-pots of type-composing machines, the metal to be melted is brought by a conveyer into a hopper, the outlet of which is controlled by a valve, which is normally locked in closed position and is unlocked at intervals, float-controlled means being provided for stopping the conveyer when the metal in the pot reaches a certain height. The metal to be fed is advanced along a table 1, Fig. 1, by a shoe 4 towards a hopper 6 opening into the pot. The shoe is advanced by a steel band 8, Fig. 3, which is wound on a roller 9 driven by a ratchetwheel 10 and a pawl 11. The pawl is pivoted bo a sliding bar 12, Fig. 1, which is reciprocated by a lever 14 operated by a part of the machine or otherwise. The pawl can be disengaged from the ratchet wheel by a rod 16 and a lever 17 operated by a float. The hopper is closed by a valve 24, Fig. 4, mounted on a pivot 34, and held in closed position by a weight or a light spring 35. The spring is powerful enough to keep back small quantities of metal, which tend to splash into the pot and cause air bubbles, but yields to a larger quantity. A stronger spring 38 afterwards comes into action to check the descent of the metal. The fall of the metal into the hopper is regulated by a beam 32 held by springs 33, and by a spring blade 37. Large blocks of metal are placed on springs 40, Fig. 1, which check their descent. The valve 24 is normally held locked by a pivoted bolt 23, Fig. 3, which is withdrawn at intervals by a star wheel 21 on the shaft of the ratchet wheel 10. The bolt is also withdrawn by a lever 22, Fig. 1, which is engaged by the feeding-shoe 4 at the end of its travel. The lever 22 also disengages the pawl 11, to enable the shoe to be drawn back to initial position. The conveyer may comprise an endless band moving always in the same direction.

Title: Control system for use with hydraulically or pneumatically operated jacks
Inventor: HOARE ROBERT GEORGE
IPC: B28C5/12
Filed: 1959-09-04
Abstract: 893,592. Pneumatic jacks. ELECTROHYDRAULICS Ltd. Sept. 2, 1960 [Sept. 4, 1959], No. 30335/59. Class 8(2). [Also in Group XXIX] A control system for a pneumatically operated jack having a main piston 11 slidable in a main chamber and a subsidiary piston rod 18 which is secured to the base of the main chamber and is in a subsidiary chamber 17 formed by an extension of the walls of the main piston rod, comprises a pump 2, selector means 3 for determining the distribution of fluid in the system, and a fluidpressure operated control device 13 for directing the flow in such a manner as firstly to provide a high speed operation of the jack under low load resistance and secondly to provide a low speed operation of the jack under high load resistance for one direction of fluid flow and to return the jack to its initial position for the opposite direction of fluid flow. The device 13 consists of a pair of pistons 23, 25 which are urged towards each other by springs 26, 27 and control a passage 19 connected to a pipe 20 leading to the main chamber of the jack, the spring 27 being stronger than the spring 26 to oppose fluid pressure in a chamber connected by pipes 8 and 16 to the selector means 3 and the subsidiary chamber 17 of the jack respectively. When the selector means is in the position shown, fluid pressure from the pump passes through pipes 8, 16 to the chamber 17 to extend the jack at high speed until the load on the jack increases and the resulting increase in pressure in pipes 8, 16 displaces the pistons 23, 25 to the right to open the passage 19 and connect the fluid pressure from the pump to the pipe 20 leading to the main chamber to extend the jack at low speed under the higher load. The pistons 23, 25 are retained in their righthand position at a lower pressure than that required to effect movement thereof by the fluid pressure in passage 19 acting on the lefthand face of piston 25. Fluid is displaced from above the main piston during extension of the jack through a pipe 28, ports 9, 10 in the selector means, and a pipe 30 loading to a tank 1. The jack can be locked in a selected position by movement of the spool 5 of the selector means to a position blocking ports 6a and 10 to prevent flow to and from the jack. To retract the jack, the spool 5 is moved to a further position wherein the pump is connected by a channel 6 in the spool to the port 10 and pipe 28 leading to the upper end of the jack, the subsidiary chamber 17 is connected by pipes 16, 8, port 6a and a passage 29 in the spool to the pipe 30 leading to the tank, and the main chamber is connected by pipe 20 and passages 19, 19a in the device 13 also to the pipe 30 leading to the tank. The areas of the main piston may be such that the speed of retraction of the jack is substantially the same as the speed of extension under low load.
Patent GB-680995-A (GB)
Title: Point-to-point ultra-short wave radio links
IPC: H04B7/155
Filed: 1948-11-22
Abstract: 680,995. Directive radio systems. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES. Nov. 22, 1948 [Nov. 22, 1947], No. 30336/48. Class 40 (vii). [Also in Group XXXV] Relates to means for reducing fading in an ultrashort wave point-to-point simplex communication system in which the angle of vertical incidence of the received waves is dependent on the variable nature of the atmosphere. In such systems the direct transmission path between the terminal stations is in general curved in the vertical plane, Fig. 2 (not shown), and for maximum transmission efficiency the vertical plane directive axes of the transmitting and receiving aerials must be aligned with the respective ends of the transmission path. According to the present invention this is achieved by automatically aligning the directive axis of each aerial with the incident direction of received signals and maintaining the orientation when using the aerial for transmission. As shown in Fig. 3, each terminal station A and B comprises a dipole 1 backed by a parabolic reflector 2 which is tiltable about horizontal axes xx<SP>1</SP> and yy<SP>1</SP> by an arm 6 bearing on a cam 4 so that the directivity pattern of each aerial may be oscillated in elevation by rotating the respective cams 4 by motors 3, the average angle of elevation of each aerial being controlled by adjusting the height of motor 3 by means of a rack 11 and pinion 10 driven by a motor 9. When transmitting from B to A, the transmitting aerial B is held stationary and the receiving aerial A is oscillated in elevation, the receiver output being alternately coupled to condensers C1 and C2, Fig. 4, when the aerial is in its extreme upper and lower positions by means of a switch 13 operated by motor 3 and the difference in the voltages across the two condensers being applied as an error voltage to actuate relay 12 controlling motor 9 which adjusts the average angle of elevation of aerial B to reduce the error voltage to zero. The Specification as open to inspection under Sect. 91 also describes a duplex system employing different wavelengths for transmission from A to B and B to A, respectively, in which the directivity of the transmitting aerial, e.g. A, is first automatically adjusted to give maximum reception at B by oscillating aerial B, transmitting the signals received at B back to A on the B-A wavelength and applying them to control the average elevation of aerial A. Aerial A is then held stationary at the optimum angle of elevation and the receiving aerial B is adjusted to its optimum angle of elevation as above. This subject-matter does not appear in the Specification as accepted.
