Title: Electrical circuit breaker for vulcanizing apparatus
IPC: H01H37/70
Filed: 1921-07-25
Abstract: 166,904. Ludi, A. July 25, 1921. Automatic circuit-breakers.-Relates to thermally released circuit-breakers for use in vulcanizing apparatus of the kind in which the bending of a heated bimetallic bar releases a spring-controlled contact member to open the heating circuit. Figs. 1 and 2 show the form claimed. The bimetallic strip 8 is secured at one end to the base by a bolt 9 and carries a pin 10 at its free end. The pin 10 passes through a slot 12 in a fixed pin or gudgeon 11 and through transverse slots in a sleeve 14 rotatably secured on the pin 11. The sleeve 14 carries a lever 13 to which is attached an insulated contact blade 24 connected to the supply by a flexible lead. When the push 23 is depressed the contact 24 touches a co-operating fixed contact 25 and the lever 14 is retained in its depressed position against the action of a spring 16 by the sharp edge of a blade spring 15 attached thereto engaging the projecting end of the pin 10. When the bimetallic strip 8 is bent sufficiently by heat it moves down the end of the pin 10 to release the blade 15 allowing the heater circuit to be automatically broken at contacts 24, 25. To adjust the releasing temperature a roller 30 with eccentric portion 26 is placed below the bar 8 at an intermediate point. The bar 13 has an adjusting arm 30 which carries a pointer 31 moving over a graduated scale. Alternatively a screw passing through the bar and a fixed hood may be employed for adjusting purposes. The Specification as open to inspection under Sect 91 (3) (a) describes a modified form of thermally-released circuit breaker in which a bimetallic strip in the form of a helix is mounted on a fixed pin and carries at its projecting end an insulated contact member. This form is illustrated in Figs. 1 (Cancelled) and 2 (Cancelled). In closing the heater circuit by depressing a push piece bearing on the projecting end of the helical strip its coils unwind and slip around the fixed pin but the friction grip between the helical strip and the pin retains the circuit closed until the strip is sufficiently heated to enable the expanded strip to relax its grip on the pin, when a retractive spring effects the breaking of the heater circuit. Means for adjusting the temperature of release comprise a coned screw for splaying out the end of the fixed pin to vary the friction grip between it and the helical bimetallic strip. This subject-matter does not appear in the Specification as accepted.

Abstract: 1329783 Welding by pressure E S B Inc 10 June 1971 [22 June 1970] 19934/71 Heading B3R [Also in Division H1] A portion of the junction between the case 10, and cover 12, both plastics, of a lead-acid battery with plates 28 and cylindrical portion 34 with rectangular portion 36 of extension 32, see also Fig. 2 (not shown) of strap 30 is formed with projections 16, 20 defining a cavity 18, 22 with square portions 24, 26 enclosing, when the case and cover are assembled, portion 36. After such assembly, a lead alloy insert 40, with hard metal drill point 46, and sharp lipped disc 48, 50 is mounted, by means of frustro-conical terminal 41 on a drill press. Rotation and translation of the tool 42 causes projections 16, 20 to be softened and penetrated by insert 40, and further translation and rotation causes a friction weld to form between extension 34, and insert 40, the plastics of container 10, 12 subsequently shrinking to seal the terminal, lipped disc 48, 50 locking into the container. A hot melt sealing material containing acid resin, 60, Fig. 3, may be used to seal the terminal assembly being initially applied between extension 34, and container 10, 12. A projection, (45), Fig. 4 (not shown), may be provided on cover 12, to support extension 32 should the square portion 36 be softened during assembly. The cover 12 and case 10 may be united by cementing, or heat sealing.

Title: Improvements in or relating to suction operating systems for motor vehicle accessories
IPC: F02M37/02
Filed: 1948-07-26
Abstract: 671,462. Supplyingliquidfuel. TRICO PRODUCTS CORPORATION. July 26. 1948 [July 26, 1947], No. 19954/48. Class 7(iii) [Also in Group XXVIII] Induction pipe suction, used for lifting fuel from a tank 6 to a supply tank 8 from which it flows to the carburetter 3 by gravity, and, if required, for actuating other accessories, e.g. a windscreen-wiper motor 58, is augmented when necessary by an electrically driven pump 11 whose motor is in a circuit including a switch operated by the ignition key 22. The pump draws air in through a port 18, Fig. 3, and forces it out from a port 19 until induction pipe suction operating through a pipe 10 draws down a plunger 30 and opens a 'switch 24, 25 which may have a snap action or be influenced by the delaying action of a permanent magnet 56. A valve 35 then allows induction pipe suction to operate through a byepass 34. The suction acts through a pipe 10 on a vacuum chamber 36, Fig. 4, a snap action valve 42 being operated by a float 40 to close either the suction passage or a vent 44. Fuel is drawn in through a pipe 7 past a non-return valve 38, and it flows to the carburetter by a pipe 9. When the tank is being replenished a valve 46 closes, and the supply is taken from a part 52 which is vented by a pipe 55. To prevent the motor coming into action when there is sufficient supply of fuel in the chamber 36, a switch 49, 50, in series with the switch 24, 25, is closed by the weight of fuel acting on a diaphragm 51, or in another arrangement (not shown), by the float 40. The diaphragm 51 may be replaced by a piston-like member and be mounted on the carburetter or in a separate chamber. When the windscreen-wiper motor 58 is used the valve bringing it into action also closes a switch in circuit with the switch 24, 25 and the electric motor. Specification 671,460, [Group XXVI], is referred to.

Exciting; regulation of exciting-machines.- Relates to the control of motors connected in series with a generator having field windings comprising a separately excited winding, a selfexcited shunt winding, and a differential series winding as described in Specification 278,467. According to the invention means are provided for decreasing the torque of the motors with increasing speed by automatic regulation of their field-strength. This may be effected as shown in Fig. 1, which shows one of the motors only, by a field winding connected across the motor armature and wound to oppose a separately excited field winding 2. In the arrangement shown in Fig. 3, resistance in the separately excited field is automatically varied by a pilot-motor 12 having opposed fields like those of the main motor in Fig. 1, or the field may be regulated according to the movement of a normally balanced relay. In further modifications, a small generator driven from the working motor acts as a differential exciter machine; provision for partly counteracting the decrease of torque during the earlier stages of rising speed may be made by giving the exciter 17, Fig. 12, a series of field winding 22. Illustrative torquespeed curves are given. Specification 281,024 also is referred to.
