Abstract: 922,151. Blow-moulding hollow articles. OWENS-ILLINOIS GLASS CO. Aug. 24, 1959 [Aug. 22, 1958; Oct. 16, 1958(2)], No. 28800/59. Class 87(2). An extruded tube A is blown into a hollow article, e.g. a toy, doll or as shown a bottle, by rotating one edge of the tube in an aperture 15 in a mould table 12, closing mould sections 16 about the tube and pinching it at its upper end, and simultaneously cutting off the closed piece of tube by a knife 22. A blowing head 25 is then raised to engage the open end of the tube, and the tube is blown to form a desired article. Whilst the article is being blown, the lower or waste portion B of the tube contained in the cavity 15 is severed from the article by (a) moving the moulds laterally over a fixed knife 30(b) reciprocating a knife 32, Fig. 8, or (c) by a rotating knife (see Figs. 9 and 10 not shown). In a modification, Figs. 10-13 (not shown), the knife may have holes, e.g. as shown in Fig. 11  to allow the pressure to be maintained in the article during cutting. It is desirable when closing the moulds, to engage the tube only at its upper end to avoid the formation of longitudinal flash. The mould and mould bed may be cooled. The moulded article and the waste material B may be removed by a blast of air. During blowing, the mould bed may be lowered to allow the tube to be continuously extruded. To allow the mould bed 12 to be adapted for different sizes of extruded tube, the aperture 15 may be formed in a removable plug 28. Fig. 7. The aperture 15 may be made larger than the diameter of the tube to cause the tube to be thinned at e.g. 29. Alternatively a variable opening 15 may be formed by members 60, Fig. 16, which can be slid laterally along the mould bed. In this modification, the knives 65 may engage in recesses 71 in the tip 70 of the blowing head 25. Pressure is maintained in the article during cutting by such an arrangement. The tip of the blowing head may move with respect to the part 74 so that the waste material B is stripped from the tip when it is lowered. In a further modification, Fig. 21, the blowing tip has a shearing edge 84 which co-operates with the knives 65. Passages 86 are provided for blowing the waste material B off the blowing head. The blowing may be assisted by suction.

Abstract: 714,135. Radio aerials. BENDIX AVIATION CORPORATION. Nov. 17, 1952 [Nov. 23, 1951], No. 29022/52. Class 40 (7) A pedestal for a radar search aerial permits the aerial to be rotated continuously in azimuth and selectively tilted during rotation to any desired angle of elevation. The aerial, Fig. 1 (not shown), comprises a reflector with a horn feed and is pivoted on the rotatable top plate 19 of the pedestal in two hinge members 14 (only one of which is shown in the drawing) so as to be tilted by the operation of a jack assembly 15 engaging a mounting flange 9 on the base of the reflector. Plate 19 is secured to the inside races of thrust bearings 21, the outer parts of which are secured to the stationary part 22 of the pedestal, and is rotated by motor-driven geared shaft 46 engaging ring gear 24. The stationary portion 22 carries two further ring gears 43, 44 for controlling the antenna tilt. Gear 43 is fixedly secured to part 22 and gear 44 is rotatable by motor-driven geared shaft 45. An extension 50 on the shaft permits manual adjustment of tilt. Engaging ring gears 43 and 44 are the input gears 47 and 48 of a differential gear assembly 47, 48, 49, 51, 39 the output gear 39 of which drives the screw 31 of the jack assembly through a ball and socket coupling 29, 30. Normally both of the ring gears are held stationary so that due to the differential action, output gear 39 also remains stationary with respect to its own axis as the top plate assembly rotates. When, however, motion is imparted to gear 44 by rotation of shaft 45 the change in the relative motion between the input gears of the differential is such that gear 39 is rotated and the aerial tilted. A rotary waveguide joint for use with the assembly is described in Specification 714,136, [Group XL(b)].

Filed: 1962-07-31
Abstract: 1,018,585. Magnetic amplifiers. LE MATERIEL ELECTRIQUE S.W. July 31, 1962 [July 31, 1961], No. 29349/62. Heading H3B. A circuit for firing controlled rectifiers comprises two modified Ramey circuits operating in different half-cycles. The transistor TS 2 , diode D 5  and reistance R 5  serve to limit the desaturating current, the transistor being cut off when the voltage across R 5  plus the conduction threshold of the transistor is greater than the conduction threshold of the diode D 5 . The resistance R 5  is variable to produce different operating conditions. This current limiting arrangement allows the circuit to be controlled by D.C. currents in the windings 1. The transistor TS 1  in the output circuit produces a pulse at the end of the half-cycle by rapidly discharging capacitor C as soon as the base voltage falls below that of the capacitor which has been charged through diode D 3  and resistance R 2 . The diode D 6  allows transistor TS 2  to be cut off by a D.C. source applied at terminals 2 and 3. The diode D 2  and resistor R 1  are stated to prevent the retention of a voltage between the output terminals G and K. It is stated that the circuit may also be used to control thyratrons or power transistors. The use of a Ramey type amplifier compensates for supply voltage fluctuations.

Abstract: 535,625. Reciprocating pumps for liquid. ERNST, W. Nov. 3, 1939, No. 29365. [Class 102 (i)] [Also in Group XXIX] A reversible variable delivery pump has its flow control member operated by a fluid-pressure servomotor and is provided with a centring device adapted to return the control member to its neutral position in the event of the pressure supply to the servomotor failing. As shown in Fig. 3, a press 13 with a differential ram 12 is operated by a reversible variable delivery pump 1 connected by pipe lines 23, 24 to the ram cylinder 19. The pipe line 24 is connected by a pipe 27 with a surge tank 3 through a non-return valve 10 and through a relief valve 9 with a main cylinder release and byepass valve 4 which is also connected to the chamber above the ram by a pipe 28 fitted with a relief valve 8. This chamber is fitted with a surge valve 5 to admit fluid to the ram during the time the press is moving up to the work said valve having an operative connection with the pipe 27 so that it is forcibly opened during the return stroke of the ram. The deliveryvarying ring 43 of the pump 1 is operated by a differential piston 48 and is loaded towards its neutral position by a pair of springs 95, 96 engaging collars 92, 93 arranged on either side of a partition 94 and co-operating with a collar 90 on a rod 89 secured to the ring 43. The piston 48 is fitted with a liner 55 having ports 57 communicating through ports 60 with an annular chamber 51 connected by a pipe 36 with an auxiliary motive fluid pump 6 and having ports 58 leading to an annular chamber 61 connected by longitudinal passages 62 in the piston with the power chamber 49. A control valve 68 loaded by a spring 65 housed in the hollow piston rod is operable either to connect the power chamber to pressure through ports 57, 60 and pipe 36 or to a return line 38 to the surge tank through ports 58, 64 and annular chamber 52. The control valve is coupled by a lever 101 and links 99, 104 with one arm 106 of a three-armed lever 108. One arm of this lever is adapted to be operated by a tappet 16 on a rod 17 secured to the press head while the third arm is linked to the core of a solenoid 113 controlled by a switch 130 actuated by a spring- loaded plunger 117 subject to the pressure in the ram cylinder and by a starter switch for the delivery motor. When the solenoid is energized the control valve is moved in the direction required to cause the pump to deliver fluid to the top of the ram, and when the pressure on the ram cylinder reaches the desired value the switch 130 is opened to break the solenoid current which causes the control valve to reverse the pump and so retract the ram. As the ram reaches its retracted position the tappet 16 moves the control valve to the position necessary to move the pump contral 9 to its neutral position. In the event of the pump failing, the springs 95, 96 move the pump control to its neutral position.

Abstract: 1,048,206. Pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 13, 1965 [July 13, 1964], No. 29590/65. Heading H3P. [Also in Division G4] In a clock pulse generator operable by a data pulse train, an oscillator with a period equal to half that of the data pulse train is connected to be switched on by data pulses delayed in delay means and off by the data pulses undelayed, and feeds frequency divider means to produce a clock pulse train having regularly occurring transitions with a period equal to that of the data pulse train. Referring to Fig. 1 (not shown), data pulses at a after delay by a one-shot 11 set a latch 12 to start an L/C oscillator 19 via an OR gate 18. The data pulses are also inverted at 17 and passed to reset the latch 12, stopping the oscillator 19. Each time the oscillator output falls, a trigger 20 is switched. The trigger 20 is also turned off by the inverted input to the oscillator 19. Accordingly, the trigger 20 provides the required clock pulse train which, when the data pulse train comes from a magnetic drum or disc store, is used to synchronize the data by gating it. The oscillator 19 may be run independently of the data input a by a further voltage level applied to the OR gate 18 (e.g. for writing data or performing housekeeping functions in an associated data processor).
