Title: Improvements in or relating to electromagnetically actuated fluid controlling valves
IPC: F16K31/10
Filed: 1960-04-20
Abstract: 946,551. Valves. REGIE NATIONAL DES USINES RENAULT. April 20, 1960 [May 12, 1959], No. 13857/60. Heading F2V. A solenoid 2, Fig. 1, within a metal or plastic housing 1, co-operates with a readily removable valve arrangement comprising a metal e.g. brass or plastic sleeve 5 embodying a seat 6 with which coacts a frusto-conical headed closure-member 7 of elastic material e.g. rubber or plastic having a cylindrical part 24 and a larger diameter part with peripheral guiding splines. A hollow closure member 4, which is slidable in the sleeve 5, is actuated by a soft-iron lever 28 to which a blade of magnetic material is attached by a rubber member 31; a cover 34 of transparent plastic material fits on the housing 1. The lever 28 is rocked by the solenoid 2 or by a rubber push button 32 housing cam means thereon which upon rotation of the button holds the lever in the operated position; the button embodies a flange 39 which acts as a non-return valve to permit venting of the housing and prevent ingression of foreign matter. The outlet fitting 41 may be disposed in any one of three different angular positions. With the lever 28 in the inoperative position shown, pressure air in the metal or plastic inlet 8 urges the closure 7 on to its seat 6, the air also passing through radial ports 17 in the closure 7 into an annular chamber and from thence to the area around the seat 6 via the peripheral splines. The closure 4 is located to vent the outlet 41 through a groove 48, radial ports 47, the interior of closure 4, ports 15, housing 1, and button 32. Upon energizing the solenoid or pressing the button 32 the lever 28 firstly moves the closure 4 until it abuts the closure 7 and closes the vent path, and then unseats the closure 7 to supply pressure air to the outlet 41 through the ports 47 and groove 48. When the lever 28 is released the closure 7 is seated by the inlet pressure and the closure 4 is moved to the vent position partly by the closure 7 and partly by the pressure acting on its end 22. In a modification, the lever actuates a rod 59, Fig. 5, to which a peripherally-splined closuremember 54 is attached; with the lever in the inoperative position the outlet is supplied with pressure air from the inlet 61 via a seat 62 normally opened by the closure 54, radial ports 56 and a groove 57. When the lever is moved to its operative position the groove 57 is vented through a seat 58 normally closed by the closure 54. The valve arrangement is suitable for rapid operation and small energizing currents.

Title: Permanent storage wire screen memory methods and apparatus
IPC: G11C17/02
Filed: 1963-04-08
Abstract: 1,010,800. Permanent stores. THOMPSON RAM WOOLDRIDGE Inc. April 8, 1963 [April 25, 1962], No. 13947/63. Heading G4A. [Also in Division H3] A permanent data store, Fig. 1, comprises a wire screen coated with magnetic material 13. Spaced rows have interrogation conductors 16a, 16b and spaced columns have sensing conductors 18a, 18b, the arrangement being such that the threading of a cell such as 14 by both an interrogation conductor and a sensing conductor represents a binary " 1 " and the threading of a cell such as 15 by neither or only one of these conductors represents a binary " 0 ". The store may be made either by bonding the wires of the screen at the intersections, coating the screen with the magnetic material 13 and then threading the insulated conductors 16a, 18a etc.; or alternatively by weaving the wires of the screen and the conductors 16a, 18a etc. in one operation such as by a Jacquard loom and then coating the screen with the material 13. In an alternative arrangement, Fig. 2, the conductors 16a, 18a etc. thread all the storage cells, but only those cells where it is desired to store a " 1 " are coated with magnetic material 13. This store may be fabricated by coating the whole screen with magnetic material and by means of masking techniques, etching away the unwanted material. In a third embodiment (Fig. 4, not shown), the screen is coated with remanent magnetic material normally maintained in one of its saturable states by a bias source, the storage of a " 1 " or " 0 " being represented by the threading or non-threading of a cell by a single sensing conductor for the store. Specification 1,010,798 is referred to.
Patent GB-1462514-A (GB)
Title: Trigger mechanisms
IPC: F16P3/00
Filed: 1974-03-29
Abstract: 1462514 Retractive switches ROBERT BOSCH GmbH 29 March 1974 [30 March 1973] 13964/74 Heading H1N A safety locking member on a trigger-operated switch for a manual machine tool, such as a portable grinder, for example, prevents the trigger being moved against a restoring force to an "ON" position until the locking member is displaced against a bias, and the locking member is then further displaceable to a position wherein the trigger is held in the "ON" position, the locking member preferably being frictionally retained in this latter position by the retractive force of the trigger. If the trigger is then pressed against its retractive force the bias on the locking member returns it in readiness to lock the trigger "OFF" when the trigger is fully released. Also, if the tool is vibrated, by being dropped, for example, the frictional retention of the locking member is lost and the tool is automatically switched off. As shown pivoted trigger 6 operates a switch 5 in the handle 4 of a tool by means of a push rod 7. A locking member 10 is slidably carried by ribs and grooves in the trigger 6. Normally a part 15 of member 10 lies under a fixed metal strip 16 and prevents trigger 6 from actuating switch 5. If member 10 is displaced against the bias of a spring 14 the strip 16 can pass into a gap adjacent part 15 and the trigger can be depressed. If member 10 is now further displaced a hooklike portion 20 overrides the turned-up end of strip 6, or may alternatively enter an aperture therein, and the force of a spring 8 urging trigger 6 to retract maintains the member 10 in position to prevent retraction of the trigger, until the force of spring 8 is counteracted by deliberate depression of trigger 6 or by accidental vibration. An extra spring 14<SP>1</SP> may come into effect upon the further displacement of member 10 and the trigger 6 may have shoulders 17, 19, to assist an operator in positioning member 10.

Title: Improvements in or relating to colour television receivers
IPC: H04N11/14
Filed: 1960-04-21
Abstract: 872,384. Multiplex radio signalling. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 21, 1960 [April 24, 1959], No. 14022/60. Class 40(5) [Also in Group XL(b) ] Relates to a colour television receiver for the reception of a signal transmitted by a system in which the transmitted signal, modulated on a carrier wave, comprises a component relating to brightness and at least one component constituted by an auxiliary carrier having modulated on it one or more signals relating to colour. In accordance with the invention, the receiver comprise a transformer 42 (in practice an I.F. transformer), a detector 15 coupled to the primary winding 41 for detection of the component constituted by a modulated auxiliary carrier, a further detector 5 coupled to the secondary winding 43 for detection of the component relating to brightness, and a delay line 52 connected in the output of detector 5 for the introduction of delay in the brightness component in order to compensate for delays introduced in the receiver into the signals relating to colour. The use of separate detectors for the brightness and colour components is stated to prevent distortion of the auxiliary carrier which arises with a single detector due to presence of the delay line in the detector output. An isolating video amplifier between the detector and delay line is not required and the line may be connected directly to the detector output without the interposition of a matching resistor. The detector input circuits are arranged to have band-pass characteristics covering the bands of the respective signals. The detector outputs include carrier (I.F.) filters. An intercarrier sound signal may be derived from the output of detector 15. A sound carrier suppression filter 46, 47 is included in the input circle of detector 5.

Filed: 1938-05-11
Abstract: 497,995. Type -- making machines. SCHNEIDER, J. May 11, 1938, No. 14073. Convention date, May 13, 1937. [Class 100 (iii)] Moulds.-In moulds of the kind in which one of the mould-blocks is adjustable in two directions at right-angles, and two others are each movable in one of these directions, the fourth mould-block is reciprocable in a direction parallel to that one of its faces that forms a wall of the mould, and is retracted after the casting to allow the type to be pushed into its path, after which it is advanced to push the type into the path of an ejector. The mould, which is adjustable for both body-width and set-width, comprises four movable blocks 7, 8, 9, 10 guided by fixed blocks 1, 2, 3, 4, mounted on a base-plate. The blocks 7, 8 are adjustable together, to vary the body-width by means of a set-screw 12, which acts on the block 7 through an intermediate thrust-block 6, the block 8 being yieldingly supported by a spring 11. The block 7 is movable between the blocks 6, 8 to effect adjustment for set-width, its position being determined by an adjustable wedge 20. The block is moved back into contact with the wedge by a lever 19, and is followed by the block 10, which is spring-pressed. After the casting, the block 9 is withdrawn a short distance, so as to open the mould, and the type is pushed out of the mould-cavity by the block 7, actuated by the lever 19. The block 10 is then withdrawn, and the type is held to the end of the block 9 by a spring catch 17. The block 9 then advances and carries the type into the path of an ejector 18, by which it is delivered. The parts 7, 9, 10 are held in contact with the blocks 8, 2 by spring-loaded guidebars 16, 14, 15. For casting low spaces, the blocks 7, 10 are divided into superposed relatively movable sections which act in known manner to close the mould-cavity at the top.
