Patent GB-592992-A (GB)
IPC: D01D1/09
Abstract: 592,992. Claw clutches; toothed gearing. POOL, W. June 4, 1945, No. 14046. [Classes 80(i) and 80(ii)] [Also in Groups XXVI and XXX] A gear-pump 36 is driven by a shaft 57 through a clutch 70 and worm 56 and wormwheel 63, and, should the pump gears be jammed, the worm rides over the now stationary wheel 63, to move axially and disengage the clutch 70. This moves a collar 72 axially, a spring-pressed tooth 74 riding over from one thread 73 to the next, to hold the clutch out of engagement. The pump may also be stopped by hand by pressing a knob 86 on a plunger 80 to rotate, and move axially, the collar 72 through rack and pinion gear 78, 79. The worm-wheel 63 drives a spindle 39 through a plate 64 and a squared end of the spindle. This drive can be disconnected by rotating a hand-wheel 67 to remove a pin 69 from the end of a fork 61 which can then swing downwards around the worm-shaft 57 axis, carrying the wheel 63 with it. Specifications 182,154, [Class 110(ii)], 565,489, 573,324, 573,325, 573,326 and 573,327, [all in Group IV], are referred to.

Patent GB-733233-A (GB)
Abstract: 733,233. Calculating - apparatus. VEB MECHANIK ASTRAWERKE. Oct. 31, 1952, No. 27510/52. Class 106(1). Function controlling mechanism of a calculating machine, presettable for the functions of sub-trial taking, total taking and addition during the progress of a previous function, comprises an operating member 1 rocked clockwise and back twice during each machine cycle and bearing a stud 2 adapted to drive a shaped coupling member 5 pivoted to an arm 19 on the totalizer engagement shaft. A spring 8 normally (Fig. 1) holds the coupling member 5 against a roller 12 on a pivoted control member 9 itself held against counterclockwise movement under the action of a spring 10 by means of a control member 13 by means of which the machine functions are set. In a subtotal operation, the control member 13 is moved counterclockwise sufficiently (2 steps) to clear the member 9 which is moved counterclockwise by its spring 10 and lowers the coupling member 5 to present a notch 7 to the stud 2 of the operating member. As the operating member 1 moves leftward, it carries the coupling member 6 with it and rocks the arm 19 to engage the totalizer (Fig. 3). In this position, a cam part 4 of the operating member 1 engages the roller 12 and rocks the member 9 back to normal position in which it is latched by a detent 16, tensioning the spring 8. The coupling member 5 is held lowered against the spring 8 by a pawl 24 which a stud 25 on the member now engages, so that it remains inactive, with the totalizer engaged, until the operating member moves leftward on its second excursion. The pawl 24 then releases the coupling member which is moved upwardly by the spring 8 to engage a notch 6 with the stud so that, as the operating member returns, it restores the coupling member 5 and disengages the totalizer. The lever 15, moved clear at the commencement of operation, finally returns to release the detent 16 and hold the member 9. In total taking, the control member 13 is adjusted counterclockwise 3 steps. The action is at first similar, but a hook 23 (Fig. 1) is engaged over a stud 21 on a lever 20 mounted on the operating member 1. This causes the lever 20 to swing relatively to the operating member so that its notched end 22 engages the stud 25 and restores the member 5 at the commencement of the second stroke of the operating member 1. In add operations, the control member 13 is adjusted one step only and does not release the member 9. The adjustment is, however, sufficient to position an arm 14 on the control member so that its notched end engages behind a stud 3 on the operating member 1 as the latter idly makes its first forward swing. Consequently, as the operating member returns towards the end of the first half-cycle of the machine, it thrusts back the arm 14 and rocks the control member 13 further to release the member 9 so that, during the second half-cycle, the totalizer is engaged to receive the set amount.

Title: Flat roof edging construction
IPC: E04D13/155
Filed: 1980-08-06
Abstract: The invention relates to a flat roof edging construction.

Patent GB-2086960-A (GB)
Title: Improved Polymer-containing Fluid and an Oil Recovery Method using the Fluid
IPC: C09K8/90
Filed: 1980-11-10
Abstract: A fluid composition suitable for injecting into oil bearing formations comprises a known hydrophilic polymer to increase viscosity and is characterized by the additional presence of an aromatic compound of the formula:   <IMAGE> wherein R1, R2 and R3 are each hydrogen or C1-C9 alkyl, the total number of carbon atoms being 0 to 9. Preferably any alkyl groups have 1 to 3 carbon atoms. The aromatic compound is used in amounts from 10 to 2000 parts per million by volume. When the amount exceeds 500 parts per million the aromatic compound hinders bacterial attack on the hydrophilic polymer. Amounts below this can still be used when the fluid is to be used in an enhanced oil recovery process, since amounts from 10 to 2000 parts per million hinder decrease in viscosity and screen factor.
