Abstract: 1,123,940. Boots &c. A. P. E. FROMANTIN. 23 Dec., 1966 [21 Feb., 1966], No. 57812/66. Heading A3B. A machine for preforming shoe uppers includes a front moulding assembly and a rear moulding assembly, each assembly consisting of a mould and an inflatable cushion. The rear mould 47 has an electric heater 51 and is mounted on a support 48. The rear cushion consists of a U-shaped frame 37 closed by a flexible membrane 38 and is mounted on the piston rod 35 of pneumatic piston and cylinder 34 for movement towards and away from the rear mould. The front mould 6 and cushion 3 are mounted on a slide which can move relative to the support 48 under the action of piston and cylinder 52 to cause a lengthwise stretching of the upper. The front mould has heaters 16. The front cushion 3 is pivoted to the slide at 53 and is swung about this pivot by push rods 55 1 , 55 2  which are operated piston and cylinder 54. A block of resilient material 14 in the cushion 3 holds the instep region of the upper against the front mould 6 before the cushion 3 is inflated. In operation the operator places an upper over the moulds 6, 47 and depresses a treadle 57 which causes the front cushion 3 to swing about its pivot 53 and engage the upper. The cushion 3 is then inflated and the front mould assembly 3, 6 moves forwardly to stretch the upper. The rear cushion 37 is then moved into engagement with the rear mould 47 and is inflated to complete the moulding operation.

Abstract: 1279106 Automatic phase and frequency control SIERRA RESEARCH CORP 28 Nov 1969 [20 Dec 1968] 58301/69 Heading H3A A synchronizing system of the type in which a clock oscillator 14 to be controlled is compared with a reference clock oscillator to derive "early" and "late" error signals 10b, 10a comprises: "bidirectional means", e.g. up-down counter 24, which produces an output to vary the oscillator frequency in response to a number of consecutive error signals in the same direction; and "intermittent means" e.g. monostables 32, 34 for momentarily shifting the oscillator frequency in response to each early or late signal. The oscillator frequency control signal on line 18 is derived from potentiometers 40 ... 43, 45 ... 48 and triggering the monostables 32, 34 actuates relay 36 or 38 to shift this control signal in a sense to compensate for the early or late pulse, thus keeping the two clocks phase locked. If the frequencies of the two clocks differ, a succession of either "early" or "late" signals will be produced, a counter 24 will count either up or down until, at a predetermined count, an output is initiated to advance or retard stepping motor 28 one step. The motor 28 actuates potentiometer 30 to change the value of the control signal on 18 to reduce the frequency difference.

Patent GB-628544-A (GB)
Abstract: 628,544. Etectric spark igniters. BENDIX AVIATION CORPORATION. March 11, 1946, No. 7503. Convention date, March 15, 1945. [Class 75(iii)] [Also in Group XXVII] An ignition system comprises in combination a spark gap, a main condenser connected to discharge across the gap, a source of electrical energy connected to charge the condenser to a voltage below the breakdown voltage of the gap and control means for rendering the gap conductive to the charge on the main condenser, the control means including an auxiliary condenser also charged from the source, a transformer having its primary winding connected to the auxiliary condenser through a circuit making device and its secondary winding connected with a pilot spark gap and a surge condenser arranged to ionise the first mentioned spark gap when the auxiliary condenser is discharged through the primary winding. As shown the discharge through a gap 6 of a condenser 7 charged to a voltage lower than the breakdown voltage of the gap is effected by creating an initiating discharge at the gap either through the main electrodes or through an auxiliary electrode to reduce the resistance of the gap. The initiating discharge is produced by the discharge of a condenser 12 which is charged from a DC source 5 which charges the condenser 7. Condenser 12 is discharged by a strobotron gaseous discharge tube 15 when the voltage on a condenser 29 is sufficient to produce a grid current and render the tube conductive. The condenser 12 then discharges through the primary winding 20 of a transformer 21. The secondary 22 of the transformer may, as shown, be connected to a spark gap condenser 25 and primary 26 of a transformer 28. When condenser 12 discharges the secondary 22 is energised and causes charging of the condenser 23 and breakdown of the spark gap, thus producing a high frequency discharge at the spark gap 6 and rendering this gap conductive to the charge on the condenser 7. Discharge of the condenser 12 may be controlled by a mechanically operated contactor. In a modification the transformer 28 is omitted the high frequency circuit being connected directly across the spark gap 6 and an inductance connected in the lead from the condenser 7. A distributer may be employed to distribute the current to a number of gaps, such as 6, and if it is desired to time the discharge accurately a contact breaker may be used in conjunction with the gaseous discharge tube ,15. The parts enclosed in the dotted line may be mounted together in a single metallic casing for radio shielding purposes. A plug and socket connector 34 may connect the parts in the casing to the remainder of the system. The sparking rate is determined by the capacity of the condenser 29 and the value of a resistance 30 through which it is discharged. The Specification as open to inspection under Sect. 91 comprises also a modification in which the condenser 25 and spark gap are omitted and the secondary winding 22 is connected between an auxiliary electrode and one of the electrodes of gap 6 or it may be directly connected across the gap. This subject-matter does not appear in the Specification as accepted.
