Title: Improvements in and relating to socket members for stud and socket fasteners
IPC: F16B21/07
Filed: 1959-09-30
Abstract: 880,352. Making stud and socket fasteners. UNITED CARR - FASTENER CORPORATION. Sept. 30, 1959 [Oct. 1, 1958], No. 33236/59. Class 83 (2). [Also in Group XXV] A method of manufacturing a socket member of a stud and socket fastener includes the steps of subjecting a blank of sheet metal to a drawing operation to form a cup, forming a series of radial slots 16 in the end wall and adjacent portions of the side wall of the cup, piercing the end wall to form a central aperture 18 such that the peripheral edge of the aperture is defined by the slotted portions of the end wall and inwardly bending the slotted portions of the end wall to form a series of resilient segments which deface a stud recurring opening such that the segments are adapted to make snapping engagement with a stud inserted into the opening. The drawing operation is a double operation to produce a small cup 14 superimposed on a large cup 14. The edge around the aperture is also turned back to form a lip 22. The inward bending of the end wall pushes the peripheral wall 24 of the cup 14 into the cup 12 and the end wall of the cup 12 becomes a wall 28 surrounding the wall 24. At this stage the diameter of the inner wall 24 at the lip 22 is smaller than its diameter at its junction with the wall 28 ; the wall 28 is then wiped towards the inner wall by using a punch which strikes the wall 28 at the junction with the wall 24 and a sizing pin curls the lip 22 to a greater extent. The wall 24 is also pressed towards the wall 28 to bring the two walls into close proximity, both walls being at an angle to the axis of the socket member. The socket is then blanked out and finished as required.

Abstract: 760,596. Moulding resin-flbre tubes &c. NAPIER & SON, Ltd., D. Nov. 17, 1954 [Nov. 30, 1953], No. 33259/53. Class 87(2). [Also in Group XXVIII] A bent tube of resinimpregnated fibrous material is made by placing a sheath, or winding a strip, of fibrous material such as fibre-glass on a withdrawal former, the fibrous material being impregnated with resin which is cured while on the bent former. The former, which may be bent to shape before or after the material is placed thereon, comprises a resilient deformable element, e.g. polyvinyl chloride, with a relatively rigid but ductile core, e.g. aluminium wire, and is removed from the moulded bent tube by first withdrawing the core and then the deformable element. The former may be made by placing an aluminium wire core 1 in a glass cylinder and surrounding it with a polyvinyl chloride mixture which is cured and the glass tube removed. A tube 3 of fibre-glass is then placed around the former and a resin such as "Marco" (Registered Trade Mark) is brushed on. The tube may alternatively be impregnated prior to placing it on the former. The former and tube are bent over a jig 5 and the synthetic resin cured. To remove the former the wire core 1 is first withdrawn and then the flexible part of the former 2. To facilitate withdrawal of the core 1 it may be coated with a lubricant which may be such that it melts or disintegrates under heat and in the latter case the core may be heated by passing an electric current through it to melt the coating before the core 1 is withdrawn from the former. The core may alternatively be of smaller diameter than the internal bore of the flexible part 2 of the former.

Title: Improvements in or relating to apparatus for controlling electrical discharges
IPC: H01J37/24
Filed: 1959-10-05
Abstract: 929,831. Automatic voltage control systems; protection arrangements. STAUFFER CHEMICAL CO. Oct. 5, 1959 [Oct. 27, 1958], No. 33608/59. Class 38 (4). In a thermionic discharge device in which the anode comprises material to be heat treated or a container therefor, the anode current is supplied from a constant current source and the anode-cathode voltage is maintained constant by automatically controlling the cathode heating current. In Fig. 1 a vacuum is maintained in a furnace chamber 1 by pumps 5 and metal 9 is melted, purified, or otherwise heat treated by electron bombardment from an electrically heated cathode 7. The discharge current is maintained substantially constant bv supplying it from a three-phase source through a constant-current network 17, delta/star transformer 27 and rectifiers 31. The high direct voltage thus applied between the cathode and the metal, which acts as an anode, is automatically maintained constant by a saturable reactor 15 varying the cathode heating current in dependence on variations of H.T. voltage detected by a potentiometer network 41, 42 and applied through a D.C. thermionic valve amplifier 47 provided with manually variable bias and gain. Horn gaps 33 protect the system against the effects of excessive voltage in the even of open circuit. Gases evolved from the heated metal may cause arcing within the chamber 1 but the consequent fall of anode voltage is effective through a potentiometer 42 to operate an adjustable thyratron relay circuit 51 which short-circuits the output of network 17 for long enough to clear the arc. Under these conditions maintenance of cathode heating above a level at which emission might cease altogether is effected by causing voltages below a predetermined value, obtained through potential divider 41, 42, to initiate operation of an adjustable thyratron oscillator incorporated in amplifier 47 to periodically increase cathode heating current. Amplifier 47 includes a changeover switch to facilitate manual setting of the cathode heating current and other characteristics prior to engaging automatic control.

Abstract: 1525741 Milking machines SED SYSTEMS Ltd 13 Aug 1975 [16 Jan 1975] 33664/75 Heading AIM [Also in Divisions F2 and G1] Milking suction is removed individually from the four teats of a cow in response to manual operation or automatically in response to a signal representing the milks conductivity dropping below a threshold value representing depletion of a respective quarter. A valve 100 has a bowl 102 communicating with inlet orifice 103 and with outlet orifices 104, 106 connected to a vacuum. Milk flows into the bowl via orifice 103 and fills first a depression 105 from which a sample of milk passes via orifice 106 to a conductivity sensor tube (see Division G1). Once depression 105 is filled milk flows through orifice 104 to the mixing bowl of the machine claw. Depletion of the quarter from which milk is flowing causes solenoid 118 to move diaphragm 114 whereby atmospheric pressure at orifice 111 acts via tubes 110, 108 to urge diaphragm 107 into bowl 102 blocking orifices 104, 106 and channel 105, releasing the teat from vacuum. A frame 122 supports the four on/ off controls in the form of blockage memoers 120, 121 for the respective orifices 111AD, 116A-D of the four valves, one for each teat. It is stated that alternatively one valve may be used to remove vacuum from all four quarters simultaneously.

Television signals applied to terminal 1 are reversed in phase in stage 2 and separated into the picture and synchronizing components respectively by biased rectifier 4 and biased valve 10, the picture component being passed through a phase-corrected low-pass filter 8 having a cut-off frequency of 5 Mc/s., the synchronizing component being passed through a low.pass filter having a cut-off frequency of 2.5 Mc/s., and the two components thereafter being combined in the common anode load 14 of output stages 9 and 13. A double-diode clamp 3 establishes the D.C. level of the signal at the grid of stage 2. A device 16 may be included in the signal path from filter 12 to output stage 13 for regenerating the synchronizing signals. The invention has application in apparatus for reproducing signals derived from a magnetic recording apparatus where the frequency of the carrier employed for recording is chosen so that the resulting modulation frequencies during synchronizing signals fall within the band of the original video signals. Interference distortions which thereby arise are eliminated by the restricted pass band applied to the synchronizing signal component. Reference is made (without giving details) to the use of an amplifier of which the frequency characteristic varies with, or is controlled by, the amplitude of the signals.

[Class 120 (iii)] [Also in Group XVI] Fabrics containing highly twisted threads of cellulose esters or ethers (other than cellulose acetate) which have been produced by a process in which at least the last part of the high twist is inserted while the threads are in a softened condition, or containing highly twisted cellulose acetate threads which have been produced by a process in which at least the last part of the high twist is inserted while the threads are in a softened condition due to the influence of an agency other than steam or hot water alone, are embossed so as to bring about displacement of the threads prior to subjecting the fabrics to the action of a crÛpeing liquid. The highly twisted threads may be obtained, for example, according to the processes described in Specifications 438,589, 438,591, 438,654, and 441,573. A number of suitable softening agents are specified. Twisting may take place on a device in which the thread is drawn off over the end of a rotating package, or a ring twister may be used. The floating ring device described in Specification 304,806, [Class 120 (iii)], may be used to restrict ballooning of the thread and the tendency of the twist to run back to the package. The total twist applied is in general less than is necessary to give a satisfactory crepe effect without the embossing treatment, for example, a twist of 40-65 turns per inch is sufficient when embossing is employed, against 70-80 without the embossing step. The surfaces of the embossing rollers may have the appearance of a crepe fabric, or they may consist of small geometrical figures or close patterns of continuous lines. The fabric may be softened, prior to the embossing operation with solvents or softener, a number of which are specified.
