Title: Improvements in or relating to a press for shaping and vulcanizing pneumatic tires
IPC: B29D30/00
Filed: 1956-05-14
Abstract: 799,761. Tyre-moulding presses. McNEIL MACHINE & ENGINEERING CO. May 14, 1956 [Feb. 24, 1956], No. 14996/56. Class 87(2). Tyre bands B are fed by buckets 48 on a conveyer band 2 to be received by a chuck 115 which is then expanded to grip the band, the chuck then being rotated about a shaft 50 by a tack 62. When the chuck is in vertical alignment with the diaphragm of the tyre vulcanizing press, the chuck is collapsed slowly to allow the band to fall onto the diaphragm. The chuck is operated by cylinders 95, 100, Fig. 10, which actuate toggle linkages 124, 125. When the chuck is completely collapsed, an arm on the chuck operates a switch (see Fig. 15, not shown) which reverses the valve to the cylinder operating the rack 62 to return the chuck to the band receiving position. At the same time, through a relay, the press operating mechanism is started. If the chuck is not clear of the mould, a safety arm 174, Fig. 1, strikes the chuck to stop the closing movement of the press. The upward movement of the chuck is limited by a plate 78, Fig. 16, which engages a pin 79 in one of several holes 83, 81. A roller 164 operates a switch 167 to drive the conveyer to bring another band over the chuck. If no bands are delivered to the chuck, they expand and contract until bands are delivered. If there is already a band on the chuck, the electrical control system is such that no bands are delivered to the chuck. The control system may also stop the press if no bands are delivered. The machine may have two conveyers delivering two bands to two chucks each co-operating with a vulcanizing press. In a modification (see Fig. 9, not shown), the band may be fed manually in which case the stop position of the chuck is arranged to be horizontal. The moulded tyre is lifted from the press by two arms (see Fig. 5, not shown), one of which then tilts to cause the tyre to slide down a take-off conveyer 14a. The press is preferably of the type described in Specification 786,347.

Title: Current limiting circuit for a solid state d.c. motor control circuit
IPC: H02H7/08
Filed: 1970-03-31
Abstract: 1,242,363. Control of D.C. motors. SQUARE D. CO. 31 March, 1970 [4 April, 1969], No. 15069/70. Heading H2J. A series motor M is supplied from battery B through rectifier SCR1 which has a quenching capacitor C1 associated with a transformer TP, TS, inductor I, and a commutating rectifier SCR2. The magnitude of a voltage spike, which appears at junction 25 when rectifier SCR2 becomes conductive, is proportional to the current through the rectifier SCR1 during its previous conducting period. A capacitor C3 detects the magnitude of the voltage spike and is connected to a thermistor TR responsive to the temperature of the rectifier SCR1 whose conductive intervals are reduced if the motor current and/or the temperature of the rectifier SCR1 become excessive. Closure of contacts FS energizes relay FC through rectifier SCR3 which is gated after a delay period whereby contacts F1, F2 are actuated to operate the motor in a forward direction. Blocking signals are then removed from an amplifier 40 and a control network 30. A multivibrator 20 alternately fires the rectifiers SCR1 and SCR2, the width of the currentpulses fed to the motor being dependent upon the output signal from network 30 on line 32. When the voltage developed across the capacitor C3 causes a zener diode D9 to break down, transistor T conducts to discharge capacitor C2, so reducing the signal on line 32 to reduce the conductive periods of the rectifier SCR1. An increase in temperature of the rectifier SCR1 increases both the resistance of the thermistor TR and the potential at the slider of potentiometer P4 for a given voltage across capacitor C3. Such increase thus tends to bias the transistor T into conduction. Diode D2 passes the inductive dischargecurrent of the motor, and diode D3 conducts during a plugging operation. Potentiometer P2 determines the rate of acceleration of the motor, potentiometer P3 sets the minimum speed, while potentiometer P controls the duration of conductive intervals of the rectifier SCR1.

Title: Improvements in or relating to motion transmission system
IPC: G05D3/12
Filed: 1945-06-14
Abstract: 603,448. Magnetic tests and measurements. BENDIX AVIATION CORPORATION. June 14, 1945, No. 15149. Convention date, May 13, 1944. [Class 37] [Also in Groups XXXVIII and XL (c)] A flux gate compass controls an indicating compass, and corrections are introduced for the magnetism of the vessel carrying the system. The flux gate 10 consists of three saturable core transformers 11, 12, 13 arranged as an equilateral triangle, and is rotatable in the earths' magnetic field to produce currents in the secondary windings of twice the frequency supplied to the primary winding from oscillator 14. The induced currents are applied to a Y- connected stator 15 of a coupling 16, the current induced in the rotor 17 being amplified at 18 and applied to a motor 21 to actuate a master compass 23 controlling one or more repeater compasses 24. The curve in Fig. 5 shows the deviation of the compass due to magnetism of the vessel carrying the system, and is corrected by the injection of a correction shown in Fig. 6. This correction is produced by a saturable core transformer 32 adjacent a bar magnet 34 and. connected to a rotatable primary winding 33a of a transformer 33 whose secondary is tapped at 120 degrees and connected to the arms of winding 15 through resistances 38, 39 and 40. The phase and magnitude of the correction is adjusted by orientation of the rotatable primary winding 33a and variation of the resistances 38, 39 and 40 respectively. The flux gate 10 may be coupled to a gyroscope, Fig. 3 (not shown). The bar magnet 34 may be removed, the transformer 32 positioned vertically and the winding 33a supplied with alternating current from the oscillator 14, Fig. 4 (not shown), so as to correct for changes in deviation caused by changes in latitude.
