Abstract: 661,974. Shoe upper conforming machine. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 27, 1950 [Feb. 26, 1949], No. 5289/49. Class 17 (i). In a shoe upper conforming machine which comes automatically to rest after the tensioning of the upper by the grippers and in which means are provided to reverse the action of the grippers, if it is necessary to readjust the upper on the last, the reversal of the drive is effected by a clutch-operated gear coupling. A shoe is positioned against an inclined shoe rest 6, Fig. 1, and the upper is tensioned by grippers 8, 10 operated from a cam shaft 4 as described in Specification 12304/03, [Class 17]. The cam shaft 4 is driven from a shaft 2, Fig. 2, by a bevel gear 58 engaged by gears 60, 62. Either the bevel gear 60 or 62 is driven when teeth 66 of a clutch 64 engage with teeth 68. The clutch 64 is normally held engaging the gear 60, as shown, to drive the cam shaft 4 in a forward direction by a spring 172 attached to a lever 170 which is connected to the lever 156 by a rod 166. When a treadle 178 connected to the lever 170 is depressed the lever 156 is pivoted through the linkage described to engage the clutch 64 with the gear 62 to reverse the drive of the cam shaft 4. The shaft 2 is driven by a clutch member 74 from a pulley 70, the starting and stopping of this drive at the appropriate stages of the cycle is effected by mechanism as described in Specification 7005/00, [Class 17], on depression of a treadle 146. In operation, to reverse the drive of the cam shaft 4 to release the gripped upper the treadle 178 is depressed, which first engages the clutch 64 with the reversing gear 62 and then, by contacting the treadle 146, engages the clutch 74. To prevent reversing the machine except on completion of the first stage of the cycle, a finger 192, connected by a linkage to a rackshaft 158 mounting the lever 156, engages a wheel 202 fast on the cam shaft 4 and is only able to enter a recess therein at the appropriate stage of the cycle. Specifications 150,424, [Class 17], and 396,086 also are referred to.

Title: Food preparations and process for the production thereof
IPC: A23L19/10
Filed: 1937-02-23
Abstract: A food product in the form of thin dry pieces which on immersion in hot cooking oil or fat expand into a light fluffy body is prepared by mixing an edible product or a flavouring, e.g. fish, meat, vegetables, fruits, or fruit essences, intimately with tapioca flour with, if desired, addition of a seasoning such as salt and pepper, adding water or milk or other suitable aqueous liquid to reduce the mixture to a pasty consistency, steaming it for about 1 1/2 -2 hours, cooling and allowing it to remain without additional treatment for about 24 hours, cutting into very thin slices and drying at low heat to remove the moisture content. In an example, 5-8 lb. of cleaned and minced fish, 3-5 lb. of tapioca flour, 4-7 eggs, 5 tablespoonfuls each of salt and sugar and one of pepper are employed, the pasty mass obtained on addition of water being moulded into shapes and laid on shallow trays on which it remains during the steaming, cooling, and keeping for 24 hours.  The product is then cut to thin slices, e.g. 1/8 in. thick, which are spread on wire mesh supports for the drying operation.  Meat, vegetable or tomato may replace the fish and may be in about equal weight to the tapioca flour, and 1-6 eggs, salt, pepper, sugar and water or milk may also be added.  In other forms, fresh or dried fruit, e.g. raspberries or blackberries, fruit juices or syrups, chocolate, cocoa, coffee, honey, ground or finely chopped nuts or spices, or both, such as cinnamon or ginger, or vanilla, almond or lemon essences are employed.  Where eggs are used as flavouring, a large proportion is employed.  U.S.A. Specification 1,926,347 is referred to.  Reference has been directed by the Comptroller to British Specification 484,468.

Title: Photographic shutter
IPC: G03B9/22
Filed: 1962-02-13
Abstract: 932,532. Photographic shutters. AGFA A.G. Feb. 13, 1962 [Feb. 23, 1961], No. 5541/62. Class 98 (1). In a pivoted blade shutter having two blade rings which rotate one after the other in the same direction to open and then close the shutter blades, the shutter setting member has a one-way locking device to allow movement in one direction only until the shutter has been released, the locking device being then disengaged by a moving part of the shutter mechanism to allow the said setting member to return to its rest position. In the form shown, the spindle 1, which passes out of the shutter housing is manually turned in direction x to tension and then release the shutter. Fixed to spindle 1 is a disc 2 having a pin 3 carrying a lever 4; the lever is spring-biased against spindle 1. As members 1-4 are turned in direction x, against a biasing spring 5, the shutter is tensioned as lever 4 engages a pin 6 on the first blade ring 7 and draws it clockwise; the pin 6 engages against the second blade ring 8, drawing that clockwise also. As lever 4 rotates clear of pin 6, ring 7 is released to run down in direction y, opening the shutter blades, followed by the delayed run down of ring 8 in the same direction to close them again. The edge of disc 2 has a ratchet portion 9 in which engages the tooth 13 of a spring-loaded pawl 10. This allows disc 2 to turn in direction x. but prevents rotation in the reverse direction. Thus if the manually operated spindle 1 is unintentionally released before the shutter has been fully tensioned, it remains locked in an intermediate position, without release of the shutter, until the tensioning is completed. Ring 8 has a projecting arm 12, which, as the ring runs down in direction y, knocks the pawl 10 out of engagement with ratchet 9, so allowing disc 2 to turn back to the rest position under spring 5.
