Title: Improvements in electrical resistors
Inventor: WALTON BRIAN
IPC: H01T4/08
Filed: 1960-04-20
Abstract: 918,666. Resistors with spark gaps. WELWYN ELECTRIC Ltd. April 13, 1961 [April 20, 1960], No. 13883/60. Class 37. An electrical resistor comprises a hollow resistance member, end terminals and at least one electrode extending inside the hollow member from one end terminal, part-way towards the other end terminal so as to define a sparkgap. In the Figure a hollow carrier member 1 carries a resistive coating 2 which is electrically connected to end caps 3. The outside of the member is coated with a layer of silicone rubber. Within the member 1 are two platinum, copper, or tungsten electrodes 4 to define a spark-gap 5, which may be adjustable by having one electrode in the form of a screw running through one of the end caps 3. The resistive coating on member 1 may be a wire winding, a film of metal, metal alloy, or a conducting oxide. The member 1 could be made of high resistivity semi-conducting material, or a composition of carbon dispersed in an organic resin, or a sintered or vitrified inorganic coating such as can be made from metallic oxides. If the member is of ceramic material a large number of discharges may produce a conductive coating on the inside of the tube which form a shunt across the resistive element. To overcome this a tube of fused silica may be fitted inside the member or the member may be made of fused silica. The hollow member may be gas-filled with difluoro-dichloro-methane compounds.

Title: Improvements in and relating to alkali silicates
IPC: C01B33/32
Filed: 1922-05-18
Abstract: sodium silicate solution is evaporated by spraying into heated air. The solution may be of 100 DEG  Tw. and may contain 2.1 parts by weight of silica to 1 part by weight of Na2O.  The spraying may be effected with the liquid at 45 DEG  C. by means of an air pressure of 65 lb. per sq. in.  Beneath the jet of liquid is a high velocity air jet at right angles to the liquid jet as in milk spraying, a pressure of 150 lb. per sq. in. being suitable. Instead of an air jet superheated stem or flue gases may be employed, or a fine spray may be produced by other means such as a whirling jet.  The spray may be directed into the top of a chamber in which the air is at 110 DEG  C. at the top and 75-85 DEG  C. at the outlet at the bottom.  Potassium silicate may be added to the sodium silicate to reduce the viscosity.

Abstract: 1317364 Fluid-pressure servomotor systems MESSERSCHMITT-BOLKOW-BLOHM GmbH 10 May 1971 [26 May 1970] 13992/71 Heading G3P In a manually-operated fluid-pressure servosystem for the control surface of an aircraft, the fluid-pressures in a movable actuator cylinder 10 are applied to pistons 37, 38 of a control valve 32, to provide assistance felt by the person operating the system. The pilot operates the valve through a rod 50, lever 44 crank 40 spindle 43 and lever 44 while the resulting movement of the cylinder causes the valve housing 30 to be restored to its original relationship with the valve. A lever 16 connected by trunnions 17 to the cylinder may be connected directly in through a further lever to the control surface, the piston 14 within the cylinder being anchored at 15 to the aircraft structure. Devices 22, 23 damp the actuator movement. Conical portions 35, 36 on the valve 32 cause the assistance to decrease as the control surface approaches the required position.

Title: Glass feeder
IPC: C03B7/086
Filed: 1962-04-13
Abstract: In a glass feeder for delivering glass in lumps to be cut off by shears, a plunger 1 is connected by an arm 2 to a vertical piston-rod 3 and piston 5 sliding in a cylinder 6. An extension sleeve 16 to the piston 5 is a bearing for a bush 17 serving as push member for the piston 5. A bolt 19 passes through two diametric bores 18 in the bush 17, forming a pivot for a link 21 which is connected by a pivot 22 to another link 23 pivotally connected at 24 to the housing 11. The links 21, 23 form a toggle lever (shown extended in Fig. 2) which on being collapsed moves the bush 17 and the main piston 5 towards the stop 7. The toggle lever is collapsed by movement of a piston 26 in a cylinder 25, the piston-rod 27 and links 22 being connected by rods 28. Compressed air from the <PICT:0949356/C1/1> <PICT:0949356/C1/2> <PICT:0949356/C1/3> control pistons 41, 42 of the air supply is passed to the cylinders through bores 3, 6, 37, 38, 39. Compressed air first enters through the bore 38 moving the piston 26 and collapsing the toggle lever, transmitting a movement to the piston 5 which increases in speed towards the end of the stroke of the piston 26 so that as the plunger is suddenly retracted a constriction is formed in the string of glass for cutting. Compressed air is then supplied to the bore 37 so that the piston 5 moves more slowly to the end of its stroke. Compressed air is then supplied to the bores 36, 39 to move the pistons back into their starting positions for the next cycle.

The motor 11 of an appliance, e.g. a floor polishing machine, having a handle 20 with a stirrup 18 pivoted at 19 to the polisher body 10, is controlled by a switch 13 whose spring-loaded plunger 14 is urged outwardly to the "on" position. The plunger .14 is controlled by a projection 21 on a lever 15 pivoted at 16 and engaged by a roller 17 on the handle 20 such that when the handle is in the vertical parking position or within about 35 degrees of such position the switch 13 is maintained " off," whereas further movement of the handle beyond a point 23 on the lever 15 permits the latter to rise and the switch to close, the lever movement being limited by a lip 22. The handle is held in the vertical position by a spring 24 apertured at 25 to receive a protuberance 26 on the stirrup, the handle being released by depressing a knob 27 on the spring 24.
