IPC: C08K5/14
Filed: 1960-12-22
Abstract: An ethylene-propylene copolymer of reduced specific viscosity of at least 4,0 and which is extended with a hydrocarbon oil in which at least 75% of the carbon atoms are aliphatic or cycloaliphatic, is cross-linked by heating with an organic peroxide and sulphur. Auxiliary cross-linking agents which may be included are red lead and quinone dioxime.  In examples optional ingredients included are carbon black, hydrogenated resin and phenolic resin.  Specifications 804,642, 810,023, 810,024, 829,150, 856,736 and 856,737 are referred to.

Title: Liquid gas separator for submersible pump
IPC: F04D9/00
Filed: 1965-10-19
Abstract: 1,124,637. Oil/gas separator. BORG-WARNER CORP. 19 Oct., 1965 [12 Nov., 1964], No. 44302/65. Heading B1M. A liquid/gas separator for a submersible well pump comprises a housing defining a reservoir chamber 15 disposed in operative association with the inlet of a submersible well pump, P, a passageway interior 17 providing fluid communication between the reservoir chamber 15 and the pump, P, inlet openings 49 in the housing providing fluid communication between the well C and the reservoir chamber, retention cups 27 defining retention chambers 29 disposed in overlying relation to and communicating with the inlet openings 49, the retention cups 27 defining inlets 103 which initially receive fluid from the well, the inlets 103 to the retention chambers being larger than the inlet openings 49 in the housing and the retention chambers 29 having a capacity sufficient to momentarily retain well fluid entering the chamber to permit entrained gas to escape from the fluid and return to the well. In action, oil from well C is drawn into retention cups 27 and through plate 49 and ports 69 and 25 by rotating impeller 23 and pump P, which impeller delivers the oil via port 83 and passageway 17 to pump P. The oil gives up entrained gas as it flows down the cups. Any gas collecting in the passageway 17 is removed by bleed 105. The pump P and impeller 23 are rotated via shaft S by motor M.

Title: Method of testing alternators
IPC: G01R31/34
Filed: 1971-09-24
Abstract: 1409654 Testing alternators LUCAS ELECTRICAL CO Ltd 11 Sept 1972 [24 Sept 1971] 44568/71 Heading G1U An alternator having a wound field 25 and a stator 11, 12, 13 (e.g. a car alternator) is tested by applying an A.C. voltage to the field winding and monitoring the signal induced in the stator winding. As described the stator signal is extracted via a fullwave rectifier either 14, 15 or 16, 15, and a multisocket 17, and if the resulting signal is either too low in amplitude, or if its waveform is too irregular, then a fault lamp 77 is energised. The test device, which includes a voltage source 27, control switches 38, 51, 52, and "fault", and "pass" indicator lamps 71, 78, is connected to the alternator under test by a multi-pin plug 17a, correspondingly referenced pins and sockets, e.g. 18a and 18, coming together. In operation, with switches 51, 52 in their positions shown, a start key 38 in depressed causing firstly a power line 33 to be connected via a resistor 39 to a contact 41, and then with further depression of the key 38, the line 33 is connected to both the contact 41 and a line 37. Application of power to contact 41 energises a relay 42 to close a normallyopen contact 43 and apply power, from a winding 31 via normally closed contacts 44, to the field winding 25. The resulting signal induced in the stator windings 11, 12, 13, is rectified by diodes 16 and applied, via contacts 51, 52 across a resistor 53. When key 38 is fully depressed, and power is applied to line 37, if the voltage across resistor 53 is sufficiently large a transistor 61 conducts sufficiently to retain transistors 68 and 71 non-conductive and conductive respectively, so that neither of two SCR's 75, 76 fires and the "pass" lamp 78 is energized. If, however, the average conduction of transistor is not sufficiently heavy, a Zener diode 66 will conduct, resulting in the firing of both SCR's 75, 76 and the energization of the "fault" lamp 77. Actuation of switch 52 selects diodes 14 instead of diodes 16, and actuation of switch 51 selects a resistor 54 instead of resistor 53, these resistors being related to the rating of the alternator under test. Further, if when the field winding 25 is first energised a leak to earth should occur, then a relay 46 is energised to open the contact 44 and prevent any damage.

A blank intended for use as a shoe upper forepart is preformed by clamping the blank, preferably in a single plane, and deforming the blank by a mould having a shape intermediate the initial shape of the blank and the shape of the last on which the forepart will ultimately be lasted. In a preferred embodiment (Fig. 3) the blank is clamped between two plates 116, 118 having cut-outs corresponding to the outline of the mould 114 and which are held together by piston and cylinders 46. The mould 114 is heated and is mounted on a plate 132 which is pivoted to a thrust rod 134 which runs in a guide 76 inclined at about 70‹ to the plane of the blank. The thrust rod 134 is raised by a piston and cylinder 68 via a toggle mechanism 56, 58. The mould 114 may also be tilted at the end of its upward movement by a piston and cylinder 80 so that the toe of the mould overlies the clamping plates 116, 118 as shown by line C. The upper clamping plate 116 may be formed with punches (not shown) which cut notches in or punch holes in the clamped periphery of the blank. In its simplest form (Fig. 1) the apparatus consists of a pair of plates 16, 18 clamped together by wing nuts and a mould 12 fixed to the end of a thrust rod 34. The shape of the mould is determined by first making a shell of deformable material having the shape of the last e.g. by vacuum forming thermoplastic sheet material on the last, then deforming the shell to a shape having its edges lying in a single plane and finally modelling the mould on the deformed shell.

Abstract: 1,122,067. Valves. ROBERTSHAW CONTROLS CO. 8 Nov., 1965 [9 Nov., 1964], No. 47292/65. Heading F2V. A gas burner supply system for a heating appliance, e.g. a water heater, is made operative by opening a manual valve 88, Fig. 2, setting the required temperature on the dial 122, Fig. 1, of a thermally responsive valve 90, Fig. 2, and pressing a button 84 to close and open movable closure members 72 and 36, respectively, thereby cutting-off the gas supply to the main burner connection 24 and opening the connection 16 to a pilot burner 22 which is lit by a match. A thermocouple 66 is heated by the pilot burner and energizes an electromagnet 48 to hold the closure member 36 open; upon releasing the button 84 the closure member 72 is spring opened to direct gas to the main burner 30 via the connection 24 which contains the valves 88 and 90. As the water temperature rises it causes elongation of a rod-and-tube thermally-responsive element 124, 126, Fig. 1, which reduces the force on a lever 112 until the set temperature is attained, whereupon a disc-type snap-acting mechanism 102 returns to the position shown and a spring 94 closes the valve 90. Decrease in water temperature causes the valve 90 to open. If the pilot burner is extinguished the electromagnet 48, Fig. 2, is de-energized and the' closure member 36 is seated to shut-off the entire gas supply to the system. The circuit to the electromagnet 48 includes a resistor 54 with a positive temperature coefficient which in the event of a malfunction of the system will reduce the current to the electromagnet and so cause the closure member 36 to be seated when the water attains a given upper temperature. The resistor 54 is positioned in the casing of valve 90 adjacent the thermal element 124, 126, as shown, or in the tube 126 of the latter, in which case it is made up of layers and has a configuration such as to provide the maximum surface in contact with the tube.
