Title: Injection-blow moulding processes and apparatus
IPC: B29C49/06
Filed: 1965-01-20
Abstract: 1,069,181. Injection-blow moulding. CONTINENTAL CAN CO. Inc. Jan. 20, 1965 [Jan. 22, 1964], No. 2526/65. Heading B5A. An injection - blow moulding apparatus comprises a stationary platen 33 and first and second movable platens 51, 52 controlled by an hydraulic motor 80 and interconnected by a lost-motion connection 88. The platen 51 supports a rotatable core assembly 104, 108 which co-operates with mould assembly 102 on the stationary platen 33 to define injection cavities and with a mould assembly 106 to define blow mould cavities. While parisons are being formed in mould sections 102 previously formed parisons are blown in mould sections 106. The cores and injection moulds are provided with fluid circulating channels. After each opening of the moulds, the core assembly is rotated through 180 degrees by a motor through a clutch 217 and worm gearing, the clutch being controlled by a switch 227 actuated by the platen 52. On rotation of the core assembly the parisons and articles are held on the cores by air-pressure, the articles being blown-off during the rotation. A cam and follower mechanism 252, 253 ensures correct alignment of the cores in the mould cavities. A timer T switched-on by a switch operated on mould closure, energizes a solenoid S which controls the valve V of the injection apparatus and at the same time compressed-air is supplied to the cores in the blow moulds which are vented during moulding. In a second embodiment the middle first movable platen carries a reciprocable unit which supports on one side a multiple core assembly and on the other side a multiple blow mould assembly, the stationary platen supports a multiple injection would assembly and a multiple blow mould assembly and the second movable platen supports a multiple core assembly.

Title: Winch and fluid control system therefor
IPC: B66D1/44
Filed: 1976-01-22
Abstract: 1491831 Valves CATERPILLAR TRACTOR CO 22 Jan 1976 [5 May 1975] 2536/76 Heading F2V [Also in Division B8] A valve 63 for controlling the supply of pressure fluid from a pump 73 to clutch and brake actuators in a winch control system (see Division B8) comprises a movably displaceable spool 67 for selectively communicating a fluid pressure supply conduit 74 with a brake line 99 on one of two clutch lines 107, 111 or with exhaust, and a pressure modulating releif valve 71 which causes a gradual increase in fluid pressure supplied from the valve 63 as the spool 67 is wound in either direction away from the exhaust or minimum supply pressure position shown. Supplied fluid from the conduit 74 passes through a groove 72 into an inlet chamber 68 which is in communication with a chamber 88 via a check valve 89 and a chamber 92 via an orifice 97. In the exhaust position shown, a groove in the spool 67 is in alignment with a passage 93 to exhaust fluid from the chamber 92, and the fluid pressure in the chamber 88 displaces a modulator spool 78 against spring bias to exhaust the inlet chamber 68 through passages 82, 83. Upon displacement of the spool 67 in either direction to communicate the fluid input groove 72 with either of the clutch outlet grooves 108, 112 and/or to communicate the inlet chamber 68 through a check valve 102, groove 101 and spool slots 103, 104 with the brake outlet grooves 98, 98<SP>1</SP>, the passage 93 becomes blocked by the spool 67 and fluid pressure builds up in the chamber 92 to displace a piston 87 to compress springs 84, 86 which move the modulator spool 78 to close the fluid exhaust path 82, 83 whereby the fluid supply pressure in the valve inlet chamber 68 increases. A spring 126 centralizes the spool 67 in the exhaust position shown, and a second spring arrangement 136 applies an increased resistance to movement of the spool into its extensive right end position (in Fig. 3) to indicate the spool position to its operator.

Title: Improvements in hydraulic brake systems
IPC: B60T17/22
Filed: 1952-02-01
Abstract: 699,333. Hydraulic brakes. HACKETT, N. H. Feb. 1, 1952 [Feb. 5, 1951], No. 2679/52. Class 103 (i). A hydraulic brake system for motor vehicles is provided with means whereby excessive movement of the brake pedal, as would be caused by a defective master cylinder or leaking fluid conduits, causes an emergency fluid supply to be brought into action and isolation of the master cylinder or defective conduit from the remaining part of the system. As shown in Fig. 2, the master cylinder 20 is connected to the pipes 23, 24 and 25, 26 leading to the front and rear wheel brake cylinders respectively by way of a unit 29, as shown in Fig. 4, having pistons 40, 41 which may be moved against springs 45, 46 to cut off the central inlet from the master cylinder from the connections 47 and 48 leading to the front and rear wheel brakes. If the movement of the brake pedal is excessive it causes chain 9 to pivot lever 32 so that a needle valve member 49 pierces the sealing cap of a gas reservoir 10. At the same time a port 52 through the needle valve spindle is moved from the position shown in Fig. 4, where it connects pipe 30 to atmosphere, to the position shown in Fig. 6, where it connects the reservoir to the unit 29. Gas passing through pipe 30 thus moves one or both of pistons 40, 41 according to whether there is a defect in a line or in the master cylinder so that the line is shut off and the master cylinder isolated, braking pressure being made operative in the effective line or lines. When the gas is released from the reservoir 10, it also operates a diaphragm switch 33 to actuate a warning lamp 34.
Patent GB-652168-A (GB)
Title: Improvements in modulating systems for ultra short waves
IPC: H03C7/02
Filed: 1948-01-29
Abstract: 652,168. Wave-guides. SADIR-CARPENTIER. Jan. 29, 1948, Nos. 2710 and 2711. Convention dates, Feb. 5, 1947 and March 21, 1947. [Class 40 (viii)] [Also in Group XL (c)] A magnetron valve operating as a modulating element interposed in a wave-guide modifies simultaneously in opposite senses the co-efficients of wave transmission and reflection, the magnetron being interposed between two sections of guide, each of which is designed to convert plane-polarized into circularly-polarized waves, or vice versa. The transmitted waves are passed to a radiating horn as, say, vertically-polarized waves, and the reflected waves are diverted away from the wave generator and are either dissipated or are fed as horizontally-polarized waves into the same radiating horn. In Fig. 1, waves from a generator are fed into a rectangular guide 1, with their electric vector horizontal. They emerge into a square guide 6 the walls of which are at 45 degrees to the horizontal. Two waves having their polarizations at right angles are propagated through the guide 6, and owing to the phase-shifting effect of the rods 3, they enter the modulating zone 7 as circularlypolarized waves, as described in Specification 1333/48, (as open to inspection under Sect. 91). The modulating means provides a variable obstruction in the zone 7 with the result that the proportion of the wave energy transmitted and reflected varies in opposite senses in the rhythm of the modulation. The transmitted energy passes through a guide section 6<SP>11</SP> similar to the section 6 and appears in the output guide 5 and horn 12 as a plane polarized wave with horizontal electric vector. The energy reflected at the modulating zone 7 passes back through the guide section 6 and appears at the face 6<SP>1</SP> as a plane-polarized wave with vertical electric vector, which wave is unable to pass along the guide 1 but is fed into a guide 10. It may be absorbed in this guide by a dummy load, but preferably, passes through a phase-shifter 13 to the neck of the horn 12. The resultant radiated wave is thus vertically-polarized at one extreme of modulation and horizontally-polarized at the other. With intermediate degrees of modulation the wave is elliptically-polarized, the eccentricity of the ellipse varying with the degree of modulation. Fig. 7 shows the modulating magnetron 23 with an axial cathode 24 and a ring anode 28, an axial magnetic field being provided by coils 29. Modulating-voltage M is applied between cathode and anode to vary the diameter of the zone occupied by the electrons, none of which reach the anode. The rods 26, 261 which operate as in Fig. 1 to convert the polarization of the waves in the guides 21, 21<SP>1</SP> may also be used to convey heating-current for the cathode from the supply CH, and modulating-voltage M and H.T. supply current for the anode-cathode circuit. The aperture in the ring anode 28 may be of roughly cruciform shape as shown in Fig. 4.

Abstract: 937,390. Inking apparatus. MIEHLE. GOSS-DEXTER Inc. Jan. 24, 1962 [Jan. 31, 1961], No. 2749/62. Class 100 (2). [Also in Group XXXIV] An inking roller 11 is supported in a printing press by its axle 15 in bearings 16 by means comprising a base 33, a pin 31 rotatably mounted in said base and extending parallel to the axis of said roller, a bearing support 21, 22 for the roller mounted eccentrically on said pin, spring means, Fig. 3 (not shown), for biasing the support in one direction of rotation about the pin, gear means 56 for rotating and holding the pin in different positions of rotation so as to shift the axis of rotation of the support 21, 22, and cam means 70 on the base 33 for shifting the support against the spring bias. The spring means hold the roller 11 which forms part of an inking train in contact with an inking cylinder 13 and a plate cylinder 14 and the roller 11 may alternatively be locked in position by a nut 47. Shifting the pin 31 by rotating the gear 56 with a worm, Fig. 5 (not shown), varies the position of the shaft 15 and the roller 11 with respect to the surfaces of the cylinders 13 and 14. The cam 70 cooperates with an arm 74 formed integrally with the section 21 of the support so that on turning the cam 70 counter clockwise the support 21, 22 is rotated counter-clockwise about the pin 31 and the axis of the axle 15 is moved along the line 18 and the roller 11 is separated from the cylinders 13, 14. At less than one quarter turn the cam 70 and the arm 74 lock the support in a position against the bias of the spring means. The support comprises two arcuate pieces 21, 22 which are hinged together at 23 and screwed together at 24. The force exerted on the support by the spring means may be adjusted by means of a threaded plug, Fig. 3 (not shown). U.S.A. Specification 2,915,009 is referred to.

Abstract: 349,488. Variable resistances. GRAMOPHONE CO., Ltd., Hayes, Middlesex, and COOPER, A. H., 104, Sarsfeld Road, Balham, London. Jan. 27, 1930, No. 2824. [Class 37.] In variable resistances, particularly for use with currents of radio frequency, the "contact member is out of electrical connection with the resistance element and operates by virtue of the capacity between these two parts. As shown, the "contact" arm 4 is bent at its end 5 into U- shape so as to embrace an arcuate resistance strip 1, the proportions being such that the capacity formed by the member 4 and the strip 1 is sufficiently high for its impedance at the frequency employed to be small compared with the resistance of the strip 1. Strips of insulating material may be fixed to the resistance element 1 so as to make light contact with the U-shaped end of the member 4 in order to locate the Y-shaped member accurately with respect to the resistance strip. The member 4 may be shaped so that the two limbs of the U-shaped end are parallel to the plane of motion of the arm. Two or more such resistance elements may be arranged one above the other and the corresponding arms pivoted to the same shaft, so that these arms may rotate either simultaneously or consecutively.

Abstract: 898,381. Dynamometers. HAMILTON, T. W. Jan. 18, 1961 [Jan. 28, 1960], No. 3151/60. Class 106 (2). [Also in Group XVIII] A pneumatic pressure transmissing device comprises a chamber with inlet means for admitting air under a pressure greater than that to be transmitted, an outlet duct in communication with the inlet and downstream thereof and a pneumatic pressure relief opening closed by a loose cover which is acted on by a damper to prevent it from vibrating and which is also acted on by a variable force, e.g. from a weighing machine (see Group XVIII), applied as a thrust along a line of action in alignment with the resultant of the pneumatic pressure in the chamber acting on the cover. When a valve 6 is opened air under pressure, from a source 5, is admitted to the pressure chamber 1 until the downward force is overcome and the cover 11 lifts, allowing air to escape between an annular projection 13, on the cover, and its seating 13a. The movement of the cover is damped by a disc 14 connected by a bolt 15 to the cover and submerged in oil in the bottom of the chamber. When there is equilibrium between the pressure and the downward thrust the valve 6 is closed gradually until the flow through the chamber is very small, under which condition the pressure in the outlet pipe 8 equals that in the chamber 1 and is in linear relation to the variable applied force. The pressure is shown by a gauge 9, calibrated to read directly in force measurement units. Alternatively, the cover 11 may be below the chamber 1, resting on the pivot point 19, its recess 12 forming the main part of the chamber.
