Abstract: 869,346. Adjusting vehicle body height; dashpots. DUNLOP RUBBER CO. Ltd. Oct. 21, 1957 [Oct. 27, 1956], No. 32824/56. Classes 108(2) and 108(3). In a height regulating valve for a vehicle suspension an arm 2, Figs. 1, 2 connected to an unsprung part of the vehicle turns a hub 14 when the wheels are deflected by road bumps. A hub 14 puts a helical spring 23, Fig. 2, under torsion which is transmitted to a plunger 40, Fig. 1, by one or other of ends 24, 25 of spring 23. Plunger 40 cannot move quickly under the action of the spring 23 as it is restrained by pistons 47, 54 which with an oil reservoir 29, a passage 30 and a restricted passage 31 form a double-acting dashpot. Air-space 37a above a flexible diaphragm 37 acts as a displacement chamber when the dashpot operates. When additional weight is added to the vehicle the springs are compressed and the arm 2 turns the hub 14 anticlockwise in Fig. 1, causing end 24 of the spring 23 to urge the plunger 40 to the right. A piston 54, urged by flange 43 will displace oil through the closed circuit formed by the passage 31, reservoir 29, passage 30 and the piston chamber. Plunger 40 pulls on a pin 69 which rocks an actuator 122 about knife edges 121 to open a compressed air inlet valve 80 by pressing on a valve-stem 81. Air under pressure is thus admitted to the pneumatic springs through an inlet 95, a non-return valve 87, inlet valve 80, passages 84, 72, chamber 28, passages 106, chamber 102 and outlet connector 103. This air raises the vehicle body and moves the arm 2 and plunger 40 in the reverse direction. Plunger 40 moves back to its mid-position undamped since oil can flow through an annular hole 53 of piston 54 when flange 43 moves away from piston 54. Inlet valve 80 is thus quickly closed when the predetermined body height is restored. If the vehicle load is reduced the springs expand and the arm 2 moves the plunger 40 to the left, piston 47 now pumping oil round the closed circuit. Head 70 of pin 69 opens exhaust-valve 112 by pushing on plunger 118 which lifts the valve off its seat. Air from the springs escapes through connector 103, valve 112 and passage 107 to the atmosphere. The spring height is thus reduced and the plunger 40 is allowed to return undamped to its mid-position by the arm 2, valve 112 closing when the predetermined body height is again restored. The time delay of the dashpot may be altered, by adjusting a restrictor valve 33 in passage 31, to prevent corrections to body height being made whilst the vehicle is cornering. The invention may be applied to both pneumatic and hydropneumatic suspension systems, but in both cases it will operate on the pneumatic chamber only.

Title: Testing flour paste pieces
IPC: G01N11/00
Filed: 1968-11-12
Granted: 1971-05-03
Abstract: The plastic qualities of flour pastes are determined by preparing round lumps of dough, under well-defined conditions, and tested in an "Alveograph". The dough is flattened between two circular plates until thickness gauges are encountered; by the removal of conical plugs a circular test piece is disengaged. This is subjected to the action of air current and the paste develops into a spherical bubble; when the thin paste membrane breaks, the pressure of the air is recored by a manometer on a graph, which characterises the flour examined. The improvements give more precise results and facilitate the use of the machine.

Abstract: 1,051,093. Control of A.C. motors; inverting. EATON YALE & TOWNE Inc. March 31, 1964 [April 2, 1963], No. 13309/64. Headings H2F and H2J. [Also in Division H3] A three-phase squirrel-cage induction motor 13 driving a battery powered truck is supplied by inverters 24, 25, 26 and its speed is controlled by varying the frequency of triggering oscillators 18, 19, 20 and simultaneously varying the average voltage by altering the proportion of each half-cycle that the motor is energized. As shown in Fig. 4 the oscillators each comprise transistors 49, 50 in a multivibrator circuit, the frequency of which is determined by the voltage from a speed control potentiometer 61 applied to control the conduction of transistors 55, 58. The oscillators are synchronized by pulses from delay circuits 21, 22 which space the phases 120 degrees apart; each such circuit comprises transistors 68, 73. the delay being adjusted by the voltage from potentiometer 61 on transistor 71 to maintain correct phase displacement at all frequencies. The inverters comprise thyristors 80, 81 extinguished by capacitor C and interconnected by transformer primary 82. The secondary 83 is in series with the motor windings and a switch 27 comprising a thyristor 88 across a diode bridge. The switching thyristor is triggered every half-cycle at a point determined by a delay circuit 41, comprising transistors 89, 90 controlled by the voltage from potentiometer 61 on transistor 93. The arrangement is such that the delay becomes smaller with increasing frequency so that the average voltage applied to the motor increases substantially proportionally with frequency. In alternative circuits (Fig. 5, not shown) ganged potentiometers replace the single one 61 and transistor control of Fig. 4. Triggering of the inverter thyristors 80, 81 is delayed at switch-on by resistor/capacitor circuit 101, 102 acting through unijunction transistor 103 and transistor 106 on a relay 47, 44 to ensure the oscillators are working and correctly phased. The motor is reversed by switching delay circuits 21, 22 to transpose two phases.

A cover member into which may be inserted the bulb end of a thermometer, a tongue depressor, or the like has at least its outer surface sterile, and is packaged in an outer envelope. The cover member may be formed from a single sheet 120, Fig. 1, doubled and sealed for example by cementing, heat-sealing, or crimping along edges 120d, one end is preferably folded several times and sealed at 120c, the other end being left open. The outer envelope 25, Fig. 7, may have overlapping portions 25c, 25a, and ripcord 26 and its ends may be folded and sealed. A line of weakening may be provided at the end of the outer envelope adjacent the open end of a cover member.

The cover member prevents bacteria on the thermometer contaminating a patient, and may be made of metal, e.g. tin or aluminium, or of a plastics. When a metal is employed an insulating band 20b of paper, cloth, or paint or plastcis coating will prevent galvanic action between the cover member and a patient's teeth-fillings. The cover member may be a tube 30, Fig. 14, having an inclined opening 30a with a bead 30b. The outer envelope may be formed by three portions 32c, 32. The portion 32c is heat-sealed to form a pocket, and the two removable portions 32 are sealed at the ends of and integral with respective portions 32c, and are provided with free flaps 32e. In a further embodiment a flexible tube comprising a cover member has a mouth indicated by a coloured portion. An outer envelope may contain a pair of cover members, and may have a tab and a line of weakening to enable it to be more easily opened. A finger-stall used for massaging a patient's gum may also constitute a cover member; the finger-stall may have a roughened portion or may have thereon a spot of massaging lotion. The outer envelope may be provided with a line along which it may be cut to avoid cutting the. finger-stall. The material of the cover member may be sterilized before or during manufacture by irradiation or by a gas such as ethylene oxide which is passed into the chamber between the outer surface of the cover member and the inner surface of the outer envelope.
