Title: Improvements in or relating to means for lubricating the cylinders of internal combustion engines
IPC: F01M7/00
Filed: 1944-07-11
Abstract: 571,940. Cylinder lubrication. DEWING, W. L. July 11, 1944, No. 13261. [Class 7 (ii)] [Also in Group XXXIV] For automatically injecting lubricant into the engine cylinder when the ignition is switched off,' a handle f is drawn back, together with a cylinder e and piston b until a pin u passes through a slot p in a cover plate q, whereupon the handle is moved angularly so that the pin makes contact with the insulated contact r and completes the ignition circuit. The cylinder a of the air pump is thus charged with air through valve m and oil is drawn from a reservoir h through pipe g<1>, non-return valve i and a hollow piston rod g into an oil pump formed by a piston d working in the cylinder e. When the ignition is switched off the loaded oil and air pumps, under the influence of a spring c, discharge their contents through a spray nozzle k into the induction pipe, the engine preferably being accelerated just prior to switching off. An alternative " off " position s for the ignition switch renders the device inoperative.

IPC: D21H17/28
Filed: 1942-09-22
Abstract: Paper pulp is sized in the beater by precipitating on to the fibres material made by reacting starch, rosin, and an alkali metal metasilicate and/or sesquisilicate until the starch is gelatinized and the resin dispersed.  Starches used may be potato, corn, rye, wheat, sago, tapioca, cassava, or arrowroot. The rosin may be germ rosin, wood rosin, colophony, or a rosin size which may contain wax. The sizing constituents may be mixed in any order, dry or wet, excepting that rosin does not disperse if added after the starch has been gelatinized by the silicate.

Abstract: 573,992. Knitting. BIRD & YEOMANS, Ltd., OSBORNE, W. T., COOK, L. T., and BEASLEY, E. G. Aug. 23, 1943, Nos. 13685/43 and 12530/44. [Class 74 (ii)] Blanks for stockings, socks and the like made by rotary knitting upon a circular machine and having the back of the leg fashioned by an upwardly convergent gap f have the heel H produced during the rotary knitting by narrowing and widening the gap. The toe T is either produced as a pouch by reciprocatory knitting, on the instep needles so that the linking line TL is on the underside of the foot, or is produced as a wedge of fabric by introducing needles into activity. In the finished hose the seam extends centrally along the foot bottom, round the heel and up the back of the leg. The splicing for the sole, heel and high heel may follow an irregular line a-e. The fashioning needles 10F are rendered active and additional splicing. needles 10I are raised to receive the splicing yarn by means of slidable jacks 13 having butts JMB, JLB for actuation by cams, and laterally extending nibs 14 engaging beneath the butts of adjacent jacks. A group of fashioning needles 1OF has at its sides a group of splicing needles 10I, and the nibs of the jacks 13 beneath the needles 10F and beneath the adjacent end jacks of the needles 10I extend laterally towards the centre of the group of needles 10F. The nibs of the remaining splicing jacks extend laterally away from the needles 10F. The end splicing jacks and a few splicing jacks adjacent to them having long butts JLB. For raising the needles to active position or to splicing height, the long butts JLB are engaged by a half-thickness cam 15 so as to be brought into the path of a pattern-controlled raising cam 17. When the needles are to be added the cam 17 is inserted. A jack raised to full height engages with its nib the butt of the adjacent jack and raises that jack to such height that on the next revolution its butt is engaged by the cam 17. To allow needles to be added at other than successive courses, a cam 22 is provided for lowering any jack butt that meets it. A half-thickness lowering cam 23 is provided for subtracting needles from active position. The cams 22, 23 are pattern controlled. Specification 574,005 is referred to.

Title: Switching circuits employing semi-conductor controlled rectifiers

Abstract: 986,113. Semi-conductor switching circuits. ROTAX Ltd. March 26, 1962 [April 17, 1961], No. 13694/61. Heading H3T. In a circuit in which two semi-conductor controlled rectifiers 3, 4 each in series with a respective load 6, 7 are connected with appropriate polarity between the positive and negative terminals 1, 2 of a supply source and a commutating capacitor 5 is connected between the junction points of each controlled rectifier with its corresponding load so that effectively bi-stable operation may be achieved by the application of triggering pulses in alternation to the gate electrodes of the two controlled rectifiers, switching of one controlled rectifier to its conducting state resulting in the trans. mission of a pulse via the capacitor 5 in a sense tending to switch the other controlled rectifier off, means are provided which prevent the application of triggering pulses to the gate electrode of the non-conductive controlled rectifier until a sufficient time has elapsed since the application of a previous triggering pulse to ensure that the state of change of the capacitor 5 is such that the pulse transmitted thereby is effective to switch the other controlled rectifier off. In the circuit illustrated, assuming that the states of rectifiers 3, 4 have just been switched to render rectifier 4 conductive and rectifier 3 non-conductive, the left-hand electrode of capacitor 5 discharges from a potential positive with respect to terminal 1 towards the potential of terminal 2. If then a triggering pulse is applied to the gate electrode of transistor 3 while its cathode is only slightly negative with respective to terminal 1, the resultant pulse transmitted through capacitor 5 could be unsufficient to turn controlled rectifier 4 off. To prevent this, Zener diode 13 prevents the flow of base current in transistor 10 until the cathode of controlled rectifier 3 has gone more than a predetermined amount negative with respect to terminal 1. Then and only then will a triggering pulse applied to the base of transistor 11 be applied to the gate electrode of the controlled rectifier. A similar circuit is associated with controlled rectifier 4. The loads one of which may be the field windings of a generator, may alternatively be connected in the anode circuits of the controlled rectifiers with suitable modifications being made to the circuit.

Abstract: 1,148,496. Jacks for use in building construction. RICHARD COSTAIN Ltd. 29 March, 1966 [31 March, 1965], No. 13738/66. Heading B8J. [Also in Division E1] In a method of constructing buildings (see Divisions E1-E2) in which successive storeys are constructed at or near ground level and subsequently raised by a plurality of jacking devices to permit the construction of a further storey therebeneath, horizontal level is maintained by a control device during a jacking operation in which each jacking device rises by a small predetermined sub-step of the order of ¢ mm. by preventing the jacking devices from again being actuated until all the jacking devices have correctly completed the previous sub-step. In a jacking system for carrying out the above process jacks 1 are arranged in groups I, II. Each jack 1 comprises a cylinder 2 in which slides a piston 3 secured to a pistonrod 4. Pressure liquid is supplied to one side 5 of the piston 3 through pipes 7, 8 from a pump 23 driven by a motor 24. A nut 9 threaded on the piston-rod 4 is movable by an auxiliary mechanism, which controls the jack stroke, comprising ratchet teeth 10 around the nut 9 co-operating with a pawl 11 actuated by an hydraulic cylinder 12 so that the nut 9 effects a follow-up movement during the jack stroke and also serves as a locking device in event of pressure failure. Switches 20, 22 and contacts 17, 18 ensure that a following ¢ mm. sub-step can only be initiated when all the jacks 1 have correctly completed the previous sub-step as indicated by signals passed to a memory device 50. A number of sub-steps form a jacking step, which may correspond to the stroke of the jacks 1 or some selected lesser distance, and after such a step the load carried by a particular jack is temporarily supported to enable the jack to be lowered and a spacer block inserted to permit a further jacking step to be made. Reference has been directed by the Comptroller to Specification 1,102,274.
