Title: Improvements relating to number dials for automatic and semi-automatic telephone systems
IPC: H04M1/34
Filed: 1920-09-03
Abstract: 171,523. Siemens Bros. &. Co., Ltd., Petithory, E. A., and Collyer, J. E. Sept. 3, 1920. Impulse-transmitters.-In impulse transmitters of the number dial type for use in automatic and semi-automate c exchange systems, in which means are provided for obtaining lost motion between the release of the dial plate and the transmission of the first impulse of each series, the spring contacts of the impulse circuits engage respectively with a metallic disc and with a disc provided with alternate conducting and insulating segments, the discs rotating together through a definite angle corresponding to the required lost motion in each direction of rotation, after which the metallic disc is held fast during the rest of the rotation o: the segmental disc. A spindle 10, Fig. 2, geared to the main spindle 3 of the fingerwheel 1 carries an insulating disc 11 provided with a segmental conducting disc 12, Fig. 5. A light metal dise or shield 13, Fig. 4, is yieldingly pressed into contact with the disc 11 by a spring 14. One impulse spring 16 rests on the shield 13 whilst the other spring 17 either rests on the shield or projects through an opening 18, making contact with the segmental disc and normally resting on a conducting segment, so that the springs 16, 17 are maintained in conducting connection. During motion in either direction, the disc 11 and shield 13 rotate together until a projection 27 on the shield strikes against a fixed stop and holds up the shield, the disc 11 rotating alone during the remainder of the motion. On the return movement of the spring and after the required lost motion is attained, the impulse spring 17 intermittently makes and breaks the impulse circuit by alternately engaging with metallic and insulated segments of the disc 11. The return motion is controlled by a spring 8 and a governor 22 engaging with a disc 23 and operating as described in Specification 14614/13. The impulse springs 16, 17 are mounted on a bracket 19, on which are also mounted springs 24, 25, 26 which serve to change over from the speaking apparatus to the impulse circuit. In a modification, the contacting disc and shield are mounted on the main spindle 3, the shield having two projections which engage a fixed stop so as to limits its rotation in either direction. Alternatively the insulating disc with metallic segments may be replaced by a metallic disc with insulating segments, in which case one spring rests in contact with the metallic face of the composite disc.

Title: Improvements in or relating to electromechanical drive and brake mechanisms for looms
Inventor: MANSSON OVE GOTTE RAGNAR
IPC: D03D51/00
Filed: 1965-06-18
Abstract: A loom drive includes a driving clutch and a braking clutch whose control cams are coupled together so that one clutch is engaged when the other is disengaged.  The cams are operated by turning an eccentric from one dead-centre to the other, the rotation being effected by an auxiliary motor and being limited by stops to half a revolution; the motor operates the eccentric through a clutch consisting of a nut running on a thread on the motor shaft, the nut being screwed into contact with the eccentric by its own inertia when the motor starts.  The normally stationary half of the braking clutch is integral with a worm wheel meshing with a worm on the motor shaft whereby, if the motor continues running after the loom has been declutched and the brake engaged, transmits drive through the braking clutch to turn the loom backwards.

Title: Improved process for producing compactly sintered ceramic masses
IPC: C04B35/195
Filed: 1937-09-24
Abstract: 502,822. Refractory substances. ROSENTHAL - ISOLATOREN CES. Sept. 24, 1937, No. 26007. Convention date, Sept. 24, 1936. [Classes 22 and 70] The slag which is obtained when calcium phosphate is reduced to phosphorus with coke and sand in an electric furnace, is used in the production of compactly sintered ceramic masses, particularly shaped articles such as electric insulators. The so-called phosphorus slag, which consists mainly of calcium silicate, may be mixed with clay and chamotte and the mixture sintered. Alternatively, by sintering a mixture of phosphorus slag and such substances as corundum, aluminium silicates, or magnesium silicates, compactly sintered ceramic masses which consist of a single crystalline substance in the systems CaO.Al2O3.SiO2 or CaO.MgO.SiO2 may be produced. Thus, by sintering a mixture of phosphorus slag, chamotte, plastic clay and corundum, a mass consisting of anorthite may be produced, while by sintering a mixture of phosphorus slag and talc, a mass consisting of diopside may be produced. Fluorspar may be added to the mixture to be sintered in order to facilitate sintering, and sodium felspar may be added in order to attain a lower sintering temperature.

Amusement apparatus.-Relates to an amusement device of the type comprising a water tank and a houseboat pivoted within the tank and adapted to be rocked about its pivot, and consists in providing within the houseboat amusement devices, mechanism for rocking the houseboat, and means for operating some of the devices from the rocking-mechanism, the other devices being operated by the movement of the houseboat. Fig. 8 shows an embodiment of the invention in which the boathouse is supported on a transverse pivot 30, Fig. 1 secured to the floor of the tank. The houseboat is rocked by an electric motor 45, Fig. 5, arranged in a housing on the superstructure of the boat, through a wheel 62 and oscillating-links 63, 65, the link 63 being pivoted to the boat and connected by cables 75 to auxiliary weights 72 moving in wells 10 beneath each end of the tank. Anchors 71 arranged in each of the wells are adapted to be moved vertically by the weights 72 when the oscillating mechanism acts against an abnormal load caused by people gathering at one end of the boat. The space beneath the floor of the tank is divided into passages 11, 15, Fig. 2, communicating with chambers 16, 19 above which are representatives 17. 20 of a whale's head and a submarine, respectively. A by-pass 21 having a window 22 communicates with the passage 11, the passage being reached from the boat through an opening 14. The motor also oscillates links 56, 67 having cords 58, 69 for operating amusement devices in the passages beneath the tank and charges an air-reservoir 51 for operating the devices pneumatically. A representation of an elephant's head projects through an opening in the side of the boat and is actuated by a pendulum 94, Fig. 9 and a cable 58. Another feature of amusement consists of a table and seats secured to the floor of the tank and the bottom of the boat, the table and seats moving relatively to one another during the movement of the boat.
