Title: Improvements in Protective Devices for Alternating Electric Current Distribution Systems.
IPC: H02H3/30
Filed: 1918-11-29
Abstract: 135,910. British Thomson - Houston Co., and Wedmore, E. B. Nov. 29, 1918. Protective arrangements.-In a protective system of the Merz-Price type, in order to avoid the operation of the relays by capacity current in the pilot wire circuit when no fault exists, relays of the watt-meter type are employed which are so adjusted as to be inoperative when current due to capacity alone flows in the pilot wires, but operating on improvement of the power factor of the pilot wire current over that corresponding to the flow of capacity current proper to the pilot wire circuit of the sound feeder. As shown, relays of the dynamometer-wattmeter type are arranged at each end of the feeder 2; one of the windings 6 constitutes the fixed field coil and is connected in shunt with the protective transformer 1 and furnished with an external resistance 7; the other winding 5 constitutes the moving coil and is coupled in series with the pilot wire 3. The capacity current in the moving coil 5 leads by some amount less than 90 degrees by reason of the resistance of the pilot wire; the resistance in the fixed field winding- circuit is adjusted so that the lagging current therein is in quadrature with the current in the coil 5. The normal currents, consequently, haveno action on the relay; or, by over-compensating, the normal currents have a restraining action varying with the load on the feeder. On leakage, an energy current will flow in the pilot wire circuit, reducing the lead of the current therein and reversing the direction of motion of the moving coil to actuate the circuit-breakers. Other forms of watt-meter relay may be employed, for example an induction watt-meter relay.

Title: Improvements in or relating to the scouring of wool
IPC: C11B11/00
Filed: 1951-08-27
Abstract: Wool grease is recovered from alkaline wool scouring liquors containing an anionic detergent by adding to the liquor a minor proportion of a water-soluble ionizable salt which does not form an insoluble reaction product with the usual compounds found in spent wool scouring liquor, the salt comprising an alkali metal or ammonium salt of an organic acid of less than 3 carbon atoms or of a mineral acid, heating the liquor until its colour darkens and it gives a specified spot test, and then separating the wool grease from the liquor by centrifuging.  The critical point is where the grease-water emulsion begins to break but has not actually broken, with no "salting out" of the soaps, detergents or proteins, and is determined by a spot test of the liquor on filter paper which shows an outside clear aqueous ring with a dark centre.  The spent liquor, after the centrifuging, is suitable for further use in scouring wool without further addition of soda ash &c. the liquor being revivified by the added salt which acts as a builder.  The preferred salt is sodium chloride.  Other suitable salts comprise potassium and ammonium chloride, sodium, potassium and ammonium sulphates and nitrates, sodium thiocyanate, borax, ammonium dichromate and ammonium acetate. In the case of sodium chloride, it is added in an amount between 2 to 13 per cent., and preferably 4 to 6 per cent. of the total weight of the liquor.  In the case of a salt other than sodium chloride, it is added in an amount equivalent in cationic effect to the amount of sodium chloride specified.  The liquor is preferably heated to boiling or above but lower temperatures may be used.

Patent GB-709054-A (GB)
Title: Improved process for obtaining the circulatory hormone callicrein
IPC: C12N9/64
Filed: 1952-08-14
Abstract: The circulatory hormone callicrein is obtained from animal pancreas or submaxillary glands by forming an aqueous mixture of the animal substance, adjusting the hydrogen ion concentration of the mixture to pH 4 to 7, heating the aqueous mixture to 45 to 60 DEG C, and removing the aqueous component from the separated fatty and proteinaceous material.  According to the example, fresh hog pancreas is minced, suspended in water, brought to a pH 4.6 by the addition of hydrochloric acid and stirred on e.g. a water bath until a temperature of 55 DEG C has been reached.  The hot solution is centrifuged or allowed to stratify, and the aqueous solution removed. It is preferred to use the pancreas or submaxillary glands of the hog, and a thermolyis temperature of 55 DEG C, as in the example, when substantially all the hormone is liberated from the animal tissue within minutes of reaching this temperature.  At 50 DEG C ten minutes is required, and at 48 DEG C one hour is required to ensure that the hormone is fully extracted into the aqueous phase.

Abstract: 743,746. Labelling machines. FAIREST, Ltd., M. July 23. 1954 [July 24, 1953], No. 20563/53. Class 73 In a machine for applying labels to bottles, which are carried by a rotating member provided with pockets 4, Fig. 2, for receiving the body labels and bottles as described in Specification 730.404, the body and neck labels are pushed from the pick-up drum 8 by pushers 13 as described in the Specification but the neck labels are transferred to a number of necklabelling mechanisms 16, Fig. 1, mounted above and in line with the pockets 4 and rotatable at the same speed as the pockets. Each mechanism 16 comprises a labelpresenting member 17 and a pair of wipers 19 located one to each side of the member 17, the arrangement being such that after transference of a neck label from a pusher 13 to a member 17, the member 17 moves forward to press the label to a bottle neck and the wipers then operate to wipe the gummed ends of the label to the sides of the neck. Each wiper comprises a flap 19, Fig. 4, of rubber with its inner edge 20 inclined to the half-angle of the tapering neck and the flaps are pivotally mounted at 19A in order to accommodate themselves to the taper. Each member 17 comprises a resilient pad 21, Fig. 3, formed with a suction aperture 22 and pivotally mounted to accommodate itself to the neck taper. The member. 17 pivots freely on a trunnion 27 and the wipers 19 are mounted on arms -28 which pass through slots 29 in the ends of the trunnion 27 and are pivoted at 28A transversely to the axis of the trunnion. A two-faced cam 30 between the upper ends of the arms 28 causes the arms to separate as the wipers 19 pass to the sides of a bottle neck and finally allows the bottle to pass freely between the wipers on removing it from the pocket 4. A plunger 37 screwed into 'the trunnion 27 is connected to the end of the piston 40 of a pneumatic cylinder 41. An arm 44 of the member 17 is urged towards the plunger 37 by a spring 45 so that downward movement of the plunger causes both the member 17 and wiper arms 28 to advance. A rotary valve plate 50 controls the movements of each piston 40, and each labelling mechanism completes its cycle of operations one in each rotation. In a modification Fig. 7 (not shown) instead of a pneumatic operation of the plunger 37, the latter is fitted with a roller 67 which runs in a camgroove 68 in a fixed cam-plate 69 to effect the rocking of the trunnion 27.

Title: Vehicle braking systems
Inventor: WALKER FREDERICK JAMES

Filed: 1964-05-20
Abstract: 1,105,552. Vehicle braking systems. HARRY FERGUSON RESEARCH Ltd. 17 May, 1965 [20 May, 1964], No. 20761/64. Heading F2F. A vehicle braking system includes wheel brakes 10, brake-applying means 26, a source 16 of hydraulic pressure fluid and a servomechanism 18 interposed between the brakes 10 and the applying means 26. The brakeapplying means which is biased by spring 27 to the left is formed with a disc valve 30 that moves on brake actuation into the aperture 22 between the two chambers 19, 20 connected respectively to the source (pump 16) and a sump 15 to restrict the fluid flow, causing the fluid pressure to rise in chamber 19. This fluid pressure is communicated to two plungers 50 operatively connected to pistons 8 of separate hydraulic brake-actuating circuits through passage 32, bore 40, chamber 45, and ducts 46, 47, 48 to thus actuate the brakes. The clearance of a lost-motion connection between the shaft 25 and a piston 36 is taken up when the valve 30 closes the aperture 22 to provide " feel " and prevent further movement of the brake-applying member 26. When the fluid pressure rises sufficiently, spring-loaded valve 44 closes the end of the bore 40 so that the fluid pressure is thereafter communicated to the plungers 50 through the restriction 51. A rotary inertia device 55 sensitive to excessive deceleration of a drive shaft connects the servomechanism to the sump 15 to partially reduce the pressure actuating the plungers 50 if the brakes are applied such that the wheels tend to lock. Sudden pressure build-up causing the wheels to lock again is prevented by restriction 51 which allows the pressure to build up slowly. When the brake-actuating member 26 is released and the pressure in chamber 19 drops a one-way valve 52 permits the fluid to drain back into the chamber 19, thus releasing the brakes. If the servo-mechanism fails the brakes are applied manually through rod 35 and cross-piece 60.
