Abstract: 1,174,458. Number senders; transistor oscillators. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1967 [23 Dec., 1966], No. 44709/67. Headings H3T and H4K. In a signal generator of the type in which the frequency of an oscillator is varied by selecting an appropriate tap on the inductance in an LC circuit, a source of potential is directly connected to the capacitor of the LC circuit and is directly connectable through switching transistors to the tappings on the inductance. The Figure shows a dual tone generator for multi-frequency telephone signalling. A pair of transistors 66 and 75 oscillate when enabled at frequencies determined by the settings of their respective LC circuits 60-1 to 60-4 and 70-1 to 70-4, and the combined output is applied via an emitter follower 100 to an output transducer 104 coupled to the microphone of a telephone handset. To select a pair of frequencies, a single key of a set 96-1 to 96-10 is depressed supplying earth potential to one column of a diode matrix. This potential is applied via two row conductors to the base of one transistor of a set 76 to 82 and to the base of one transistor of a set 84 to 90. These transistors are thus switched to conduction supplying an enabling potential to the corresponding taps 60-1 to 60-4 and 70-1 to 70-4 causing the circuit to oscillate at the selected frequencies.

[Also in Division B5] A component of a heel end moulding machine consists of a lining sheet 15 of polytetrafluorethylene or similar polyfluorocarbon material moulded to the shape of the heel end of a shoe and a support 16 of elastomeric material e.g. polyurethane, moulded around the sheet. The component is incorporated in a mould of the type described in Specifications 1,091,082 and 1,108,552. The component is made by stretching the sheet of polyfluorocarbon material around a heel shaped form 21 (Fig. 5) using a stretching plate 22 to which the sheet is clamped by means of plates 23, 24 and screws 25, the plate 22 being moved by a screw 28. Before being stretched the outer surface of the sheet may be treated with a substance which facilitates subsequent bonding e.g. sodium etch treatment. After stretching the internal stresses in the sheet are removed by heat treatment, and the sheet is transferred whilst remaining on the form 21 to a mould for application of the supporting means 16 which is applied to it by a moulding operation. The outer-etched surface of the sheet is first coated with a bonding liquid e.g. an isocyanate modified resin, and the elastomeric material to form the supporting means 16 is then poured into the mould to mould it around the stretched lining sheet and simultaneously bond it to the sheet.

Switches 19, 25 are operated in a timed sequence and control operation of the printing units of a multiple-unit printing machine, whenever actuation of electromagnet 12 initiates the sequence. When the electromagnet 12 is actuated the pin 18 pushes the first of a series of spring-loaded lugs 8, which extend around the circumference of stationary plate 2, away from its stop 10, so that it is engaged by one of the pins 6, which are mounted on a rotating member 3, and carried by it to a position in which the pin disengages from its end, in consequence of its rotation about pivot 7. Before reaching this position however, the lug 8 has engaged the next lug 8, forcing it off its stop and causing it, in turn, to be engaged by the pin 6. A wave of disturbance and return of the lugs 8 is, therefore, propagated around the plate 2, at the angular velocity of the member 3, and actuates the switches 19, 25. The member 3 carries pins 6 on both sides, and co-operates with separate plates 2 and series of switches, arranged to respectively start and stop the various units of the machine in accordance with movement of sheets to be printed therethrough.

Abstract: 466,164. Spray carburetters. HILVETY, G. C. S. VON. Nov. 15, 1935, No. 31714. Convention date, Nov. 15, 1934. [Class 7 (iii)] During overrunning with the throttle valve partially open the supply of fuel through a fuel nozzle is interrupted by a device comprising a pneumatic chamber having therein a diaphragm &c., one side of which is subject to atmospheric pressure and the other side to suction on the engine side of the throttle valve, the diaphragm controlling a valve to close it when the suction in the intake exceeds a predetermined value. During overrunning, suction acting through a pipe 9 displaces a diaphragm 5 in a casing 1 until a stud thereon engages the end of a rod 12 in an adjustable insulated bushing 11 thus completing an electric circuit through a spring 13, the casing 1, a conductor 13<1>, battery 14, conductor 17, magnet 16 and conductor 15 connected to the rod 12. The magnet rocks on arm 22 to displace a bar 19 through apertures in which fuel normally can flow to main and idling nozzles 18, 33, Calibrated orifices 8, 10 on either side of the diaphragm, open the casing 1 to the atmosphere. The circuit may be shunted by a signal light mounted on the dashboard. As shown, the diaphragm and the magnet are mounted in a single unit, but they may be arranged separately. Where multiple nozzles are employed, each has a valve cock and all the cocks are operated simultaneously by the bar 19. The electromagnet device may be replaced by one operated by suction. The Specification as open to inspection under Sect. 91, describes a diaphragm chamber 40, Fig. 6 (Cancelled), in which a diaphragm 3 is displaced by suction, applied through a conduit 9, to open a valve 47 normally closing a passage 51 leading to a second diaphragm chamber 52. Suction applied to this second diaphragm 53 causes it to actuate a lever 63 which closes a valve 73 in the idling conduit 71. The displacement of the diaphragm 53 closes an electric circuit including a pilot lamp 27. The diaphragm 53 and valve 73 may be incorporated in a single unit or the diaphragms 3, 53 may be replaced by pistons. This subject-matter does not appear in the Specification as accepted.
