Abstract: 510,234. Handling load-containers. SPINK, A., and WALKER BROS. (WIGAN), Ltd. Dec. 28, 1937, Nos. 35896/37 and 2853/38. [Class 78 (iv)] [Also in Group XXXII] A container A, Fig. 1, and a container-carrying vehicle are each provided with slides B, D adapted to co-operate with one another, the slides D on the vehicle being mounted on a tipping frame C while a winch is provided on the vehicle for pulling the container on to the frame when horizontal and for raising and lowering the container when the frame is inclined. The cable from the winch passes around a jockey pulley at the front end of the tipping frame and is detachably secured to the container. Means are also provided for anchoring the container to the frame C. To guide the container-slides B on to the vehicle-slides D, the front ends of the container-slides may converge or the rear ends of the vehicle-slides be splayed outwardly. A tailboard J is hinged at K on the container:so as to swing upwardly into a position in which it rests on the container. A platform L supports the container during loading. In a modification,Fig. 6, the container-slides B are formed at their front ends with downwardly-inclined parts N continued by short horizontal parts O and upwardly-curved parts P and the front ends of the vehicle-slides are fitted with co-operating inclined and hori-. zontal parts. Thus when the container is drawn off the vehicle manually or by a winch &c. the inclined parts N travel up the inclined parts on the vehicle producing a two-point contact between the slides to facilitate the movement of the container on to the platform which is provided with an inclined front end over which the inclined rear end M of the container travels until it overbalances when a two-point contact again occurs between the container and platform. In a further modification Fig. 10, a substantially similar arrangement of inclined and horizontal sliding surfaces is employed but the inclined parts N on the container-slides B are omitted, the container has a roller W or coaxially-arranged wheels at its front end projecting below the slides B, the vehicle is fitted at its rear end with a roller or wheels X projecting above the slides D, and the platform at its front end is similarly fitted with a roller or wheels so that rolling contact is effected between the parts when the container is moved.

Abstract: 974,668. Tubes. ROBINSON & SONS Ltd. Oct. 4, 1962 [Oct. 6, 1961], No. 36095/61. Heading F2P. A method of dividing a tube comprising concentric inner and outer layers into containers each having an internal or external shoulder at both ends includes the steps of cutting the outer layer circumferentially at a plurality of predetermined lines simultaneously and forming an internal or external shoulder 14 on the end of the tube. The inner layer is then cut circumferentially at a first line K 4  offset from a cut D 2  in the outer layer and the container (Fig. 5, not shown) so formed is separated from the end of a tube. The inner layer is cut a second time to form a second container, the cutting of the inner layer being repeated until the tube has been divided into a plurality of containers. The steps formed by the shoulders may be of equal or unequal depth in each container. In the latter case annular portions are cut in the inner or outer layer corresponding to the inequality in step depth. The successive cuts in the inner layer may, however, be equally spaced, the inner and outer layers of each container formed thereby being telescoped to produce similarly dimensioned containers.

Filed: 1972-08-03
Abstract: 1393608 Spring units; spring power-storing mechanism INTERNATIONAL BUSINESS MACHINES CORP 3 Aug 1972 [27 Aug 1971] 36206/72 Heading F2S A mechanism consists of a rod, such as an armature 10, rigidly secured, as by nuts 16 on threaded rods 11 connected to its ends, to an inner edge of each of a pair of annular spring discs 12, 13, each with curved slots in the zone between its inner and outer edges (and arranged so that the slots of one disc are directed in the opposite sense to those of the other disc), the outer edges being secured to a fixed support (e.g. housing 14, by pole shoes 17, 18 and clamping pieces 19, 20), so that the rod can adopt either of two stable positions along its axis, e.g. against either of two adjustable end stops 24, 25. The springs 12, 13 are first clamped to the armature 10 at their inner edges and the outer  edge of one spring, say 13, is clamped against the adjacent pole shoe 18 by the raised edge of the adjacent piece 20. The rod is then moved axially and is caused by spring 13 to rotate about its axis and thus rotate the spring 12 clamped to it. The outer edge of spring 12 is then clamped to the pole shoe 17 by the disc 19 by tightening of screws 23. Arcuate slots 21 in the spring 12 permit its rotation before the tightening of the screws. On removal of the axial force moving the rod, the latter returns to one of the stable end positions with a biasing and change in shape of the springs 12, 13. Now, upon axial force being applied to the rod (armature 10), e.g. by exciting a field coil 29, the rod is moved axially against the spring tension until it reaches a midposition and then rapidly passes the position because of spring force in the same direction; it moves to an end position against one of the adjustable stops 24, 25.

Title: Improvements in and relating to quick-action electric switches
IPC: H01H71/50
Filed: 1930-12-04
Abstract: 362,158. Snap-action switches. JOLLY, R. W., 10, South Park Road, Wimbledon, and BRITISH ELECTRIC METERS, Ltd., 45, Westminster Bridge Road, both in London. Dec. 4, 1930, No. 36578. [Class 38 (v).] A quick-action switch, more particularly for use in a prepayment electricity meter, has a contactarm g pivoted at h and carrying a bridging contact j for engaging fixed contacts k. A pin d carried by a crank pivoted at c engages a slot f on the contact-arm g, and a tension spring n connects the pin d with a fixed point m. In operation after the insertion of a coin, a gear sector a is rotated by hand to engage a gear sector connected with the crank pin d to turn it in a clockwise direction through 180‹. The spring then passes its dead centre and the crank being then free of the gear sector a moves further to close the switch. The pin d is arrested on the down stroke by an abutment t on a trip lever q pivoted at r. The lever q cannot move owing to a pin u engaging the raised end portion of a slot v in an auxiliary trip-lever w pivoted at x. The lever w tends to turn in an anticlockwise direction until a pin y engages the periphery of a wheel z. As current is consumed, the wheel z is turned by the metering mechanism until a gap 2 registers with the pin y. The lever w rises allowing the lever q to turn. The pin d then slips off the abutment t and moves round to open the switch under the action of the spring n. The levers q, w then return under gravity to their initial positions, a weight 3 being provided on the lever q for this purpose.

Abstract: 1530370 Citric acid by fermentation STANDARD MESSO DUISBURG GES FUR CHEMIETECHNIK mbH & CO 10 Sept 1976 [27 Sept 1975] 37564/76 Heading C2C [Also in Divisions C6 and F4]  A process for the fermentation of a nutrient substrate, exemplified by the fermentation of molasses by Aspergillus to produce citric acid, involves inoculating the substrate with the ferment in a germ-free chamber, allowing the ferment in a germination phase to extend over the entire surface of the substrate and effecting a fermentation phase wherein the fermentation product, citric acid is produced, and in the germination phase highly sterile air which has been pretreated through a coarse-fine-absolute filter, U-V sluice and superheated to about 120‹ C., is supplied in a small amount giving a slight excess pressure in the chamber whereby to prevent any extraneous infection from entering, and the fermenting substrate is independently heated by heaters, while in the exothermic fermentation phase the supply of highly sterile air and the heating are switched off and fresh, filtered unconditioned air is supplied to the chamber as cooling air so that the temperature of the fermenting substrate is kept substantially constant. The citric acid produced may be precipitated from solution as calcium citrate using milk of lime. Referring to the figure, the air conditioning system for use with germ-free chamber 2 consists essentially of an air system 4 for the germination phase including coarse filter 4-1, fan 4À2, fine filter 4À3, absolute filter 4À4, U-V sluice 4À5, superheater (to 120‹ C) 4À6 and valve 4À7, and a further air system 5 for the fermentation phase including coarse filter 5À1, fan 5À2, absolute filter 5À3 and valve 5À4. During the germination phase in which the fungus extends to cover the entire surface of the molasses substrate in the individual troughs 3, a small amount of highly sterile air is admitted from system 4 to produce an overpressure of from 5 mm. to 50 mm. water gauge in the chamber and the chamber is heated by heaters 6 fitted on each of the walls, and the cover and floor of the chamber. During the fermentation phase, in which the developed fungus exothermically ferments the molasses to produce citric acid, the chamber is supplied with sufficient fresh, filtered unconditioned air from system 5 to keep the temperature substantially constant, the air being vented through an exhaust valve 7. The air system 4 and heaters 6 are then not used.
