Abstract: 1,050,446. Rectifying. WESTERN ELECTRIC CO. Inc. June 20, 1963 [June 21, 1962], No. 24566/63. Heading H2F. [Also in Division G3] In a controlled rectifying circuit there are two transformers, the primary of one is connected directly to the alternating current supply, the primary of the other is connected to the alternating current supply through a controlling device and the outputs of the two transformers are combined together and then rectified. With this arrangement the range of output voltage control is limited (Figs. 6a and 6b, not shown) but some of the rectifiers can be cheaper, uncontrolled elements. The transformers T1, T2 (Fig. 1) are both fed from the alternating current source 10, 12, transformer T1 being fed directly while transformer T2 is fed through the controlling device 38. The outputs of the two transformers are combined, one end of secondary winding 15 of transformer T1 being connected to the centre tap of the secondary winding of the transformer T2, so that the current provided by the transformer T1 does not induce any voltage in the primary of transformer T2 which might damage the controlling device 38. The combined current is rectified by the six rectifier elements shown and passed through smoothing choke 28 to the output terminals 30, 32. The controlling device 38 may be driven by a control circuit 34 which measures the voltage or current in the direct current circuit. The controlling device 38 may comprise a semi-conductor controlled rectifier connected across a bridge of diodes the other diagonal of the bridge being in series with the transformer T2 (Fig. 2a, not shown). Alternatively a pair of reverse parallel connected semiconductor controlled rectifiers or a saturable transformer may be used (Figs. 2b and 2c, not shown). In the arrangement shown in Fig. 4 the secondaries of the two transformers are connected in series to a simple bridge rectifier. Transformer T2 has two primaries 80, 81, each primary being connected to the supply through its own controlling device. The arrangement is such that with one controlling device the voltages in the transformer secondaries are added but with the other controlling device the secondary voltages are subtracted. A suitable magnetic amplifier firing control circuit for this embodiment is described (Figs. 7a and 7b, not shown). Polyphase arrangements of both embodiments are described (Figs. 3 and 5, not shown).

Abstract: 1,052,616. Gas-liquid separator. AVERYHARDOLL Ltd. May 13, 1965 [May 14, 1964; Oct. 23, 1964], No. 20322/65. Heading B1M. [Also in Division F2] A separator for gases entrained by liquid comprises a separation chamber and a drainage tank, the communication between them being controlled by a valve, and the valve being by-passed by a secondary flow-path, the secondary flow path including a restricted portion, the entry of liquid into the secondary flow path being controlled by an obturator itself controlled by a float in the separation chamber, and the position of the valve being controlled by the difference in pressure between the separation chamber and that part of the secondary flow-path situated upstream of the restricted portion. In Fig. 1, diaphragm 2 of valve 3 divides separation chamber 11 from by-pass chamber 6. When the pressure of gas in chamber 11 causes float 7 to be lowered, the by-pass route 10-6-4-12 is closed. The increased pressure in 11 causes valve 3 to open permitting liquid to flow through passage 5 into drainage chamber 12 (Fig. 2 not shown). In the apparatus of Fig. 3 (not shown), if the delivery from chamber 16 is slowed down or stopped, the consequent rise in pressure in chamber 15 causes the partial or complete closure of duct 17 by piston 28.

Abstract: 1,231,597. Moulding tyres. K. ZANGL. 30 Sept., 1968 [10 Oct., 1967; 11 Sept., 1968], No. 46348/68. Heading B5A. A pneumatic tyre is placed in a vulcanizing press, comprising opposed mould halves which when closed abut along a plane perpendicular to the mould cavity axis, by locating the tyre between the open mould halves, pulling the tyre beads apart to decrease the tyre diameter and then forcing the beads together to decrease the tyre diameter for facilitating mould closure. The press includes mould halves 2a, 2b with adjacent bead engaging rings 4a, 4b at the peripheries of plates 4, 4<SP>1</SP> which may move relative their respective mould halves such that the sum of such relative movements is at least equal to the distance between the inner edges 2a<SP>1</SP>, 2b<SP>1</SP> of the closed mould cavity, Fig. 4. The bead ring 4b is urged upwardly relative its mould half by springs 6b, and the bead ring 4a is connected by a bayonet joint to the lower end of a cylinder 9 urged downwardly relative the upper mould half by springs 6a. After placing the t yre on the lower bead ring the lower mould half and its associated heating ring 3b is raised until both bead rings are forced into the tyre beads. Steam under pressure is admitted to the tyre interior through a duct 5 and the tyre beads are thereby urged apart against the pressure of the springs 6a, 6b to decrease the external diameter of the tyre, Fig. 3; the steam is released and the mould halves brought together, and simultaneously the bead rings are forced together, Fig. 4. The tyre is then repressurized and vulcanization effected, Fig. 5 (not shown). Condensate or hot water, if the latter is used for vulcanization, may be removed from the tyre by opening the press and forcing the bead rings apart so that water may flow from the duct 5. Additional condensate drawoff conduits may be located between the plates 4, 4<SP>1</SP> and connected to the duct 5 whereby pressure medium supplied through duct 10 forces condensate from the tyre interior. In the modification of Fig. 9, the upper bead ring 4a is connected by a bayonet joint to the lower end of a cylinder 900 driven vertically by a fluid motor 905, whereby the tyre bead rings are brought together to decrease the tyre diameter before the press is closed. Each bead ring may have a stepped sealing surface which engages the tyre bead, and a sealing ring may be located in a groove in the sealing surface.

Abstract: 1,238,492. Stop watches. CHIAP HUA CLOCKS & WATCHES Ltd. July 4, 1969 [Oct.29, 1968], No.51266/68. Heading G3T. A stop watch comprises a spring 13 secured to a geared segment 10 to bias the segment for rotation about a pivot 12, a shaft 5 bearing a gear 9 which meshes with the segment, a sweep hand and a winding knob being secured to the shaft, a further gear 8 on the shaft coupled through a gear train 17, 19, 21, 23, 24 to an escapement 26, 27 to control the rotational speed of the shaft and a control knob 31 to permit or prevent operation of the escapement. Rotation of the winding knob causes the gear 9 to rotate the segment 10 in a clockwise direction thus tensioning the spring 13. During winding the gear 8 displaces the shaft 18 of the gears 17, 19 to prevent the escapement restricting the winding but a spring 38 biases the gear 19 back into engagement with the gear 21 at the termination of the winding. The escapement comprises a star wheel 26 and a balance weight 27 provided with projections 29. The balance weight oscillates about a shaft 28 and may be provided with an adjustment in the form of a screw which may be screwed in or out. A flange 34 of a spring-biased plunger 30 attached to knob 31 normally engages the balance weight, however, depression of the knob frees the weight thus allowing the sweep hand to rotate over a dial marked from 0 to 60 seconds. Parts of the watch such as the back, the glass and a mounting plate for the gear train are preferably made of plastics.
