Title: Improvements relating to methods of coating the body of an electrical component having connecting wires with a layer of a synthetic resin
IPC: H01G13/00
Filed: 1965-09-29
Abstract: The body of an electrical component e.g. ceramic capacitors, resistors, having connecting wires is coated with a layer of a synthetic resin, which may be thermoplastic, by applying a deposit of discrete liquid droplets on the body, applying a coating of powder of a synthetic resin over the deposit, and then heating the coated body so that the liquid evaporates and the powder coalesces.  The coalesced material may be hardened by heating.  The liquid may be deionized water or a liquid having not too high an evaporation rate e.g. glycols.  The coated component may be incorporated into a printed wiring assembly. The powder may be applied by spraying, by passing through a curtain of falling powder, or by dipping in a gas-fluidised bed of the powder.  Suitable synthetic resins are polyethylene, polyvinylchloride, ethoxyline resins, cellulose esters, silicon epoxy resins, chlorinated polyethers and polyamides, which be mixed with solid plasticizers e.g. triphenylphosphate or p-toluenesulphonamide, or mixtures of these resins.  The coating process may be repeated several times.

Filed: 1967-09-15
Abstract: 1,191,508. Control of D.C. motors. ARROW ELECTRIC SWITCHES Ltd. 15 Sept., 1967 [12 Jan., 1967], No. 42184/67. Heading H2J. [Also in Division H1] A combined variableresistance and switch arrangement for controlling an electric motor comprises a finger-operated trigger member 12 with insulated compartments 13, 14, respectively containing a spring-pressed bridging contact 20 and a frictionally gripped brush contact 30 which co-operate respectively with fixed contacts 26, 50, 41, and resistance strip 37 and fixed contact 40. Contacts 40, 41 are extensions of a sheet metal member which also serves as a heat sink for a SCR. To this end extensions 44, 45 and (43) (Fig. 3, not shown) form heat dissipating fins closely adjacent the walls of the electrically insulating casing 10. The SCR container is frictionally held by further extensions of the metal member 47, 48. Before pressure is applied to trigger 12, the whole of movable contact 20 rests on fixed contact 26 and the brush contact 30 is in the maximum resistance position, connecting fixed contact 40 to the left-hand end of resistance strip 37. As pressure is applied progressively to trigger 12, brush contact 30 moves over resistance strip 37 cutting out of the circuit more and more of the resistance; bridging contact 20 connects immediately with fixed contact 50 to include the SCR circuit, which provides a motor speed determined by the resistance 37. Upon further pressure the movable contact 20 disengaged from fixed contact 50 and engages immediately with fixed contact 41 to by-pass the SCR circuit. To facilitate rapid making and breaking of circuits, the toe part 21 of the bridging contact 20 is bevelled as shown and contact 50 is raised slightly above contact 41. Fig. 7 shows the SCR circuit, lead wires 29 and 57 being connected to fixed contact 26 and point on heat sink 49, respectively.

Abstract: 1,215,275. Weighing apparatus. FORD MOTOR CO. Ltd. Aug.26, 1969, No.42425/69. Heading G1W. In a vehicle having a load supporting body spring-mounted relative to an axle 1, an hydraulic load cell is so arranged between the axle and the spring-mounting that deflection of a resilient wall 11 in the load cell due to a load in the supporting body provides displacement of liquid indicative of the weight of the load. As shown, the load cell comprises a pair of chambers 3, 4 each defined by a dished member 10 and a resilient wall 11 having a central enlargement 14, the chambers 3, 4 being spaced by spacers 16, 17, filled with liquid, and connected by liquid filled conduits 18, 19 provided with valves 7, 8 to a load indicating device 9. The device 9 comprises a cylinder 20 in which is movable a piston 21 connected to a pivotally mounted pointer 22 associated with a scale 24. The load cell is fixed to the spring-mounting so that when the valves 7, 8 are open, downward deflection of the body relative to the axle due to a load causes liquid flow out of the chamber 3 which is reduced in volume and into the chamber 4 which is correspondingly increased in volume by an amount proportional to the load, such liquid displacement effecting a corresponding deflection of the pointer 22. Two load cells may be provided at opposite ends of the axle 1 and connected to a common load indicating device 9. The valves 7, 8 are closed when the vehicle is in motion and may be arranged to be automatically opened when the vehicle is parked and closed when the vehicle is moved.

Title: Improvements in or relating to the production of sponge iron
IPC: C21B13/08
Filed: 1965-10-08
Abstract: <PICT:1123406/C6-C7/1> Fine-grained sponge iron such as that produced by reduction of ore in a rotary kiln is moistened and by means of a pelletizing plate or a granulating drum caused to roll upon itself whereby pellets are formed which are then hardened by heat-treatment at 500 DEG -1200 DEG  C.  The latter step may be carried out by returning the pellets to the fuel zone of the reduction kiln.  In a preferred embodiment carbon, in the form of caking coal with or without other carbonaceous material, is incorporated in the pellets, while strength-increasing materials such as lime or bentonile may also be added, as may ore concentrates such as magnetite, or oxides of alloying elements such as nickel, manganese, chromium or vanadium. The resultant pellets may be charged to a steelmaking converter or other furnace.  As illustrated sponge iron reduced in kiln 1 passes through cooler 2 to screen 7 where hardened pellets are discharged at 18.  The fine material passing the screen is magnetically separated at 8, the metallic fraction being ground in grinder 10, and again magnetically separated at 11. The metallic product then passes by conveyer 12, where the desired additions are made, to mixer 13 and pelletiser 14, the product from which is returned to the final zone of the kiln by feeder 4.

Abstract: 1351696 Shearing RHEINMETALL GmbH 16 Sept 1971 [13 Nov 1970] 43137/71 Heading B3W A cutting device for shearing steel ropes, chains, &c. underwater comprises a cutting charge 2 mounted in a carrier 1, an arm 9 pivotable about a shaft 24 to an open position, shown in broken line in Fig. 2, and means such as a wire 12 restraining the arm from pivoting to the open position, the arm in the open position being disposed to co-operate with the cable to cause detonation of the cutting charge 2. The arm 9, urged by a spring 11 to the open position, is of angle section and mounted within the arm is a rocker 23 also pivoted about shaft 24. A detonation pin 25 projects from one end of the rocker and a spring 26 urges the other end into engagement with a push rod 22. The push rod 22 is located in a socket in the arm 9 which communicates with a piston chamber 19 which has an inlet slot 20 and an outlet bore 21 to ambient water. A spring-urged piston-rod 17 extending into the chamber 19 carries a collar 16 which normally engages the underside of a ring 15 integral with a plate 13. The plate 13 is pivoted to the arm 9 at 14 and connected to the arm by a shear pin 9a. A cable encountering the device, which has a stabilizer 3 to which a tow rope 5 is connected, severs the wire 12 allowing the spring 11 to move the arm 9 to the open position. The cable then presses the plate 13 shearing the pin 9a so that the plate pivots, to a position in which the collar 16 can pass through ring 15. The piston-rod through the water column 28 in chamber 19 forces the push rod 22 against rocker 23 which pivots, causing the pin 25 to puncture a detonator 7. The metal casing of the charge acts as a shear blade, a ceramic plate 6 screening the tow rope from the blast. The retaining wire 12 may be removed by hand before the device is put in the water.
