Title: Improvements in or relating to electromagnetic relays for use in railway signalling or like systems
IPC: B61L1/18
Filed: 1924-01-19
Abstract: 232,664. Automatic Telephone Manufacturing Co., Ltd., and Hudd, A. E. Jan. 19, 1924. Electrical systems, automatic.-On a track circuit supplied with alternating or pulsating current, a rectifying relay, which is substantially aperiodic is used to rectify current from the same source which supplies the track rails circuit in order to energize a direct current relay at the receiving end. The rectifying relay is preferably of the kind described in Specification 156,353, [Class 38 (v), Electric switches &c.], having mechanical means for adjusting the phase. A polarized direct current relay is used and gives three-position signals by reversal of the phase of the current supplied directly to the relay with regard to that supplied to the track rails. Fig. 4 shows the last-mentioned arrangement. The track rails are supplied from mains 45 through a transformer 46 and condenser 47; the rectifying relay 48 has an aperiodic armature which closes the circuit from transformer 50 to the direct current relay 51 during one-half of each cycle and, according to the setting of a switch (not shown), which controls the current supplied to the transformer 50, a rectified current in one or other direction is supplied to the relay 57 and causes the armature 54 to close contacts 57 or 58 for controlling signals. A shunt resistance 59 is placed across the relay 57 to prevent chattering. The Provisional Specification describes a modified circuit for the relay 51.

Title: Tape drive control
Inventor: ATSUMI KATSUYA
IPC: G11B15/30
Filed: 1964-01-14
Abstract: 1,040,111. Magnetic recording &c. apparatus. AKAI ELECTRIC CO. Ltd. Jan. 14, 1964, No. 1577/64. Heading G5R. A magnetic tape recorder comprises a stop key, a playing key, a recording key, a fast winding key, and a fast reverse winding key, each key being adapted to cause appropriate operation of the recorder; and the playing and recording keys and the fast winding keys are associated in pairs with a locking bar so that depression of one key of a pair inhibits depression of both keys of the other pair. Referring to Fig. 7, depression of key P causes it and its associated stem 10p to rotate. The stem 10p moves over a spring-loaded rotatable stop member 19 and slides over its edge so that it is locked in position by the stop member. Actuation of another key rotates the stop member and allows the depressed key to return under the action of a return spring (not shown). The stop member 19 is extended adjacent the stop key so that the stop key is not locked when it is depressed. The stem 10p is provided at its lower end with two projections which engage in notches 11a and 11b, Fig. 5, in an associated slide 11p As shown in Fig. 5, the slides 11r and 11p (associated with the record and play keys respectively) are provided with L-shaped slots 29r and 29p through which project projections 22r and 22p formed on a locking bar 22 which is spring-biased towards the right. Similarly, slides 11w and 11f, associated respectively with fast reverse winding and fast winding keys, are provided with slots engaged by projections in the locking bar. Thus with slide 11w operated, as shown, slides 11r and 11p are locked but slide 11f is free to move. Similarly, if slide 11r or 11p is operated, slides 11w and 11f are locked. The play key initiates normal drive but the record key merely switches the head connections, so both keys must be depressed to initiate a recording operation. The slides 11w and 11f are adapted to rotate a drive shaft clockwise or anti-clockwise to bring one of two friction wheels into engagement with a supply or a take-up reel, Figs. 10-12 (not shown). Movement of both slides simultaneously leaves the shaft in a neutral position.

Filed: 1945-01-22
Abstract: 610,315. Gauging surface roughness. SHAW, H. Jan. 22, 1945, No. 1698. [Class 106 (ii)] An instrument for indicating and/or recording the roughness of a surface comprises a stylus, means for moving it across the surface and so supporting it that it follows at least those contours of the surface which lie above a fixed reference plane, and means which summate either those periods during which the stylus point lies on or above the fixed reference plane, or those periods when the contours of the surface lie below this plane. As shown, the instrument comprises a stylus A traversed across the surface X so that its point, if not deflected by the material phase of the surface, would keep on the datum line B-B. The stylus is secured to a lever A<1> which is pivoted about C on a lever D carried by a link F, actuated by a cam I. A rider G on lever D rests on a stationary reference surface H contacting the surface X. The downward or upward limit of movement of the stylus is determined by screws N or N<1>. The vertical movement of the stylus A is caused to generate or modulate a current in a pick-up device of the electrodynamic, piezo-electric, electrostatic, or electromagnetic type operating an indicating or recording device. The latter is shown as a member J rotating at a constant speed, which may be synchronized with the traverse of the stylus A, and a member K which is normally stationary, but on energization of a coil M thereon by the pick-up is connected to and driven by the member J. The arrangement may be such that the members J, K are connected only.during the periods during which the stylus is moving away from the datum line B-B.

Title: Improvements in photo electrical apparatus for the reproduction of sound films
IPC: G11B7/00
Filed: 1938-01-19
Abstract: 509,700. Recording and reproducing sound. KOLB, O. K. Jan. 19, 1938, No. 1706. [Class 40 (ii)] In a sound film reproducing system in which dual photo-sensitive elements are used, means are provided in order to facilitate testing of balance for feeding the exciter lamp with A.C. or unsmoothed rectified current when derived as an alternative to direct smoothed current. The exciter lamp 1 is connected by means of switch arms 13, 14 either, in the lower position, directly to a transformer 21 or, in the upper position, through a rectifying and smoothing unit 12. Light from the lamp passes through a push-pull type sound track 3 to two photo-electric elements 8, 9 connected in push pull. When the lamp is fed with alternating current any lack of balance in the electrical system is apparent as a hum. Correction may be applied by adjusting the voltages of the anodes of the photo-electric cells across which a potentiometer 24 is connected and which are connected to one pole of a source of E.M.F. through resistances 23, 22. Decoupling resistances 25, 26 and condensers 27, 28 are provided. The sliding contact 31 of the potentiometer is connected to the positive pole of the source of E.M.F. and provides the required adjustment. An alternative arrangement, Fig. 2 (not shown), provides rectified supply current which, by means of the switching device, is fed to the lamp either smoothed or unsmoothed.

Abstract: 1,167,851. Tensile testing apparatus. COURTAULDS Ltd. Jan. 13, 1967 [Jan.14, 1966], No.1823/66. Heading G1S. A tensile testing apparatus comprises two pairs of clamps 7, 8 and 29, 30, an inner pair 7, 8 for clamping a specimen 6 so as to define a gauge length of the specimen between them, and an outer pair for clamping the specimen outside the inner pair, and means 15, 19 for increasing the length of the specimen path such that the length of the path between the clamps of the outer pair is increased at a rate greater than the inner pair of clamps but such that the rate of increase of the path length between the inner clamps is greater than that between the adjacent inner and outer clamps. The clamps may be positioned so that the specimen follows a straight path or in the case of a flexible specimen a rectangular path. The inner clamps 7, 8 are simple gripping jaws. The remainder of the specimen is passed round pulley 22, 23, 25, 26, 20 and 21 to the outer clamps 29, 30 which are in the form of bosses against which the specimen is clamped. The clamp 7 is mounted on a pivoted arm 9 on which is fixed a rod 13 which is in turn connected to a balance for measuring the load on the yarn specimen. The clamp 8 is mounted on a vertical plate 15 which is vertically slidable along guides 17, the movement of the plate being controlled by a rod 19 connected to a driving mechanism. The clamps 29, 30 are mounted on a floating member 28. In use the specimen is positioned in the clamps and over the pulleys as shown before the plate 15 is moved vertically downwards, the tension in the gauge length being measured through the rod 13 on a balance (not shown). The adjustments necessary when the tension between the inner and outer clamps becomes too great may be controlled electrically or pneumatically.

Title: Sludge discharge control apparatus
IPC: B01D21/00
Filed: 1972-01-17
Abstract: 1433324 Fluid-pressure servomotor systems HAM BAKER & CO Ltd 17 April 1973 [17 Jan 1972] 2051/72 Heading G3P [Also in Division B1] An apparatus for controlling the discharge of sludge from a settlement tank 10 comprises a chamber 15 having a valve 21 controlling the flow of sludge into the chamber through inlet 17 and control means for automatically closing valve 21  when sludge in the chamber reaches a predetermined level. Settlement tank 10 is continuously supplied with water containing suspended solids, e.g. sewage, the solids settling on the tank bottom 12 and the solid-free water flowing over the tank rim which acts as a weir. The sludge is discharged through tank outlet 13 via pipe 18 to chamber 15 at regular intervals determined by a timing mechanism. When the latter operates, solenoid valve 31 is actuated to cause hydraulic piston and cylinder actuator 26 to partially open chamber outlet valve 22, the degree of opening being determined by an adjustable limit switch 32 controlling solenoid valve 51. Simultaneously solenoid valve 30 operates to cause actuator 25 to open valve 21 and permit sludge to enter chamber 15 under the effect of the differential head between level L 1 of water in tank 10 and level of sludge in the chamber. The latter level reaches a certain value, at which it remains until all the sludge has been discharged from tank 10, some sludge flowing past outlet valve 22 to a disposal point. When solid-free water starts to enter chamber 15 the sludge density therein is reduced causing the level to rise until the sludge contacts an electrode 29. The latter thereupon causes solenoid valve 30 to operate actuator 25 to close valve 21 and shut-off the flow of water from tank 10. In a modification opening and closing of outlet valve 22 is controlled in response to sludge level as sensed by electrode 54. In the event of blockage of chamber outlet 19 solenoid valve 31 may be manually operated to fully open and close valve 22 to clear the obstruction. Valve 22 may be arranged to close if inlet valve 21 fails to close correctly. In other modifications valves 21, 22 may be operated mechanically rather than hydraulically or outlet valve 22 may be replaced by a fixed restriction. The hydraulic circuit for actuators 25, 26 includes an electric motor 35 driving pump 36, reservoir 38 and an accumulator 47.

Title: Improvements in and relating to the control of trimming and/or balancing tabs
IPC: B64C13/00
Filed: 1944-02-05
Abstract: 572,494. Controlling aircraft. BOULTON PAUL AIRCRAFT, Ltd., and NORTH, J. D. Feb. 5, 1944, No. 2146. [Class 4] Means for controlling a trimming or balancing tab comprises an electric motor for moving the tab to balance the aerodynamic load on the control surface, and an electric switch for controlling energization of the motor, arranged in the operative connection between the pilot's control member and the control surface so as to be operated against the action of a spring to energize the motor when the load transmitted by the operative connection exceeds a predetermined value. The invention is shown applied to elevators 7, the tabs 2 being actuated through irreversible screw-and-nut mechanism 4 and links 5 by reversible electric motors 1 carried by arms 6 attached to the elevators, the motors acting as mass balances for the latter. The lower end of the pilot's control column 8 moves in a frame 9 against compression springs, electric micro-switches being fitted at the ends of the frame and arranged to close when the springs exert a predetermined force. A switch 13 provided on the control column enables the pilot to initiate trimming movement of the tabs whenever he so desired after closure of one of the micro-switches. With the switch 13 closed, prior to movement of the control column, actuation of the latter results in the tabs 2 functioning automatically as balance tabs when either of the micro-switches is closed. Movement of the tabs continues until the aerodynamic force on the elevators is reduced to such an extent that the load on the control column is insufficient to hold the micro-switch closed against the spring loading. The characteristics of the driving motors may be such that the operation of the tabs lags behind that necessary to give complete balance, the load on the pilot's control increasing with the rate of movement, thus giving a sense of " feel." Continuous trimming and balancing is obtained if the switch 13 is not provided.

Title: Steam power plant
IPC: F22B35/10
Filed: 1971-01-18
Abstract: 1338068 Steam generators SULZER BROS Ltd 18 Jan 1971 [19 Jan 1970] 2351/71 Heading F4A In a steam plant, heat is extracted from steam produced in the evaporator 8 to heat the feedwater, and upon occurrence of a peak load, the rate of heat extraction is temporarily reduced. A forced circulation plant has a feedwater vessel 1 from which the water is drawn by pump 2 and delivered through valve 48 to an economizer 3 leading to a mixing vessel 27 in parallel with a separator 39. The water is drawn through line 25 by circulation pump 26 and forced through the evaporator 8 heated by a burner 42. Steam passes through three-way valve 21<SP>1</SP> into the separator 39 and then through two-stage superheater 10 into live steam line 11 which feeds a turbine 12. Thic comprises two stages with an intermediate reheater 31. Exhaust steam from the turbine is condensed at 13 and delivered by pump 14 into the vessel 1. During normal operation some steam is fed from valve 21<SP>1</SP> through pipe 40 into the mixer 27 to heat the feedwater. Valve 21<SP>1</SP> is operated by an actuator 37 controlled by means 36 responsive to the live steam pressure measured by detector 33, or alternatively to the rate of flow. When peak load occurs the pressure falls and valve 21<SP>1</SP> reduces the steam supply to the mixer 27. Simultaneously the pressure detector 33 acts on controller 34 and load controller 35 to open valve 44 and increase the fuel supply to burner 42. The three-way valve 21<SP>1</SP>is also influenced by the flow of water to an injection line 29 which controls the degree of superheat. This flow is controlled by a valve 30 responsive to the live steam temperature. The flow of feedwater to the economizer 3 is controlled by the level in the separator 39 acting upon a sensor 46 which controls the ! valve 48. In another embodiment, Fig. 3 (not shown), the separator and mixer form a single unit (39) and the three-way valve (21<SP>11</SP>) is disposed between this separator and the economizer 3. This valve (21<SP>11</SP>) controls the quantity of feedwater sprayed into the separator and is itself controlled by the output of an electric generator (61) driven by the turbine. In a further embodiment, Fig. 1 (not shown), applied to a natural circulation steam plant, the three-way valve (21) is disposed between the economizer 3 and a steam/water drum (5, and controls the quantity of feedwater sprayed into the drum. The three-way valve is itself controlled in dependence upon the water level in the drum, the actual flow rate of feedwater and the flow rate of steam on the live steam line. The fuel supply is also increased at peak load.
