Title: Improvements in and relating to synchronization devices for change-speed gears
IPC: F16D23/06
Filed: 1960-05-03
Abstract: 926,702. Positive clutches. TATRA, NARODNI PODNIK. May 3, 1960 [May 6, 1959], No. 15624/60. Class 80 (2). A friction synchronized positive clutch comprises clutch pins 16, 21 carried by a member 1 fast with the driven shaft 2, which pins are moved axially into engagement with holes 18 in a rotatably mounted gear 26 or 27, having coned friction surfaces 13, by pins 7 fast with an axially slidable shift sleeve 6, initial movement of which acts through resilient segments 10 to move a balk ring 12, having a slot 14 with cam sided balking notches which coact with mating faces of the pin 7, into frictional engagement with the clutch surfaces 13 whereupon frictional drag turns the ring 12 to balk further movement of the sleeve 6 and pin 7. On synchronism further movement of the pins 7 moves the clutch pins 16 towards the gear 26 or 27 and points thereon detect and align the holes 18 with the clutch pins 16 which then move into full engagement with the holes and also act through guide members 20, 29 interconnected by a member 33 to move flat ended clutch pins 21 into engagement with the holes. During disengagement the clutch pins are positioned centrally by spring-pressed rollers 24 between the guides 20, 29 which engage a notch 23 in the member 1.
Patent GB-810643-A (GB)
Title: A process for the simultaneous production of refined shark liver oil and vitamin a concentrates along with the recovery of other therapeutically active by-products
IPC: A61K31/59
Filed: 1957-05-16
Abstract: Vitamin A concentrate and a refined shark liver oil containing Vitamin A are obtained from crude shark liver oil by allowing the crude oil to separate into solid and liquid phases, isolating the solid stearine phase from the liquid oil phase, refining the isolated oil phase to obtain refined oil containing Vitamin A; saponifying the isolated stearine phase, solvent-extracting the unsaponified matter, evaporating off the solvent and separating the cholesterol present in the extract to yield Vitamin A concentrate.  The separation of stearine may be effected by stoving the oil at about 15 DEG  C.  The liquid oil phase may be alkali refined and deodorized with steam at a temperature not exceeding 115 DEG  C.  The refined oil thus produced may be diluted with cottonseed oil and other oil diluent.  The saponification of the isolated stearine is preferably effected in alcoholic medium with the gradual addition of about twice the calculated amount of alkali, in aqueous solution, required for complete saponification and the unsaponified matter is extracted with peroxide-free ether. The soaps of the saponified stearine may be converted into calcium salts of fatty acids after the solvent extraction, by the addition of an aqueous solution of a calcium salt. An example describes the preparation of a Vitamin A concentrate from crude shark liver oil.

Title: Error detecting means for counters
IPC: G06M1/276
Filed: 1970-04-07
Abstract: 1,262,621. Counter resetting mechanisms. S. MULLER, and H. MULLER, [trading as J. HENGSTLER K.G.]. 7 April, 1970 [20 June, 1969], No. 16305/70. Heading G4D. A counter has a number of digit wheels and a transfer mechanism comprising a number of pinions which are taken out of mesh with the digit wheels during zero-resetting. A mechanical feeler determines whether the resetting has been correctly performed by taking a certain position only when all the digit wheels have been reset and when the pinions are in mesh. Each digit wheel 2 has a cam 3 and an associated resetting lever 4. When key 5 is pressed the transfer pinions 6 are displaced vertically downwards and the levers 4 rotate to reset the wheels 3 to the zero position illustrated. At the same time pin 12 rotates a spring-loaded pawl 13 mounted on feeler rake 10 until it passes beneath it, allowing the pawl to return to the horizontal. When key 5 is released its upward movement causes pin 12 to act on the inclined surface of pawl 13 so attempting to rotate feeler rake 10 about axis 19. If the counter is correctly reset this rotation will take place, feeler fingers 14 entering deep notches 15 and button 11 being depressed to generate an electric signal. If any digit wheel is not correctly reset the feeler rake 10 cannot rotate so no signal can be generated and the key can not rise to its rest position. Similarly, if the transfer pinions 6 have not meshed with the digit wheels as in Fig. 5, nose 17 of an arm 7 carrying the pinions abuts part of the feeler rake, so preventing its rotation. The digit wheels may have a two-part construction, Fig. 6 (not shown), one part carrying the teeth and the other the cam and deep notch, or may be of unitary construction, Fig. 7 (not shown). If the counter includes electromagnetic resetting means an associated relay gives an output if the counter is not correctly reset. This output may be used to initiate a further resetting operation.

Abstract: 792,084. Making envelopes. DOETSCH, W. June 7, 1955 [June 11, 1954], No. 16319/55. Class 94(2). A paper strip 1 from a roll 2 is fed by rollers 3, 4 to a helical knife 5 which cuts it into blanks of rhomboid shape, and the blanks are fed by rollers 7, 8 to a drum 10 which rotates each blank, while being fed forward in the same direction of travel as the strip 1, about an axis passing through and normal to the blank, so that it is brought into a position with one diagonal parallel to the direction of travel for subsequent operations. The drum 10, Fig. 10, has radial rotary tubular nozzles 11 communicating with with suction passages 15 controlled by a stationary valve 16. Each nozzle has an arm 12 engaging a stationary cam 13, and after a nozzle has gripped a blank at its centre it rotates it in its own plane through the required angle. The nozzles are returned by springs 12<SP>1</SP>. The blanks are conveyed from the drum 10 by roller 18 to a cutter 20 which cuts notches in the sides of the blank, and on to folding means 28 which fold over the side flaps, and gumming roller 30 which applies adhesive to the folded-over flaps. Next the blank passes to creasing knives 38, 39 for the bottom and closing flaps and folding means 36, 37 for the bottom flap. Suction roller 34 then conveys the folded and stuck envelope to rollers 42, 43 rotating at a reduced speed so that the envelopes are brought together in overlapping relation between belts 44, 45 which carry them past a gum box 47 to apply adhesive to the exposed margins of the closing flaps. This adhesive is dried as the envelopes are guided by rollers 49, 50 adjacent a heater 56 which directs hot air against them. At rollers 54, 55 the belts 44, 45 separate and the envelopes are passed by rollers 58, 59 to a folding pocket 60 where their direction of movement is reversed and rollers 58, 62 fold down the closing flap. A roller 64 co-operating with a belt 66 then stacks the finished envelopes on edge on a table 69. The adhesive for the closing flaps may be applied to the paper strip and dried before it is cut, the means for arranging the envelopes in overlapping relation and the gum box 47 and heater 56 then being omitted. By moving the cam 13 clear of the levers 12 the rotation of the suction nozzles 12 may be stopped and the machine can then be used with blanks 71 already formed and stacked in a pile, the bottom blank being drawn off by an oscillatory sucker 70 and fed to the drum 10 by a roller 74.
