Title: Moulding of dough products
IPC: A21C11/08
Filed: 1971-04-19
Abstract: 1351805 Moulding dough WERNER LEHARA Inc 19 April 1971 [16 March 1970] 22426/71 Heading B5A One side of a dough product 200a is embossed, and the product then conveyed for further processing, with the embossed side contacting the conveying means and the non-embossed side exposed. As described for making pasties, dough D from a hopper 26 is fed into an embossed die 24 in a die roller 22, compressed by a roller 28 and scraped level by a scraper 30. The dough product 200a is transferred to a canvas or cotton belt 42 by a rubber roller 44 periodically pressed against the die roller 22. The product is carried upside down with the embossed side exposed, and is held on the belt 42 by wetting or a dough film. A nosing bar 52 and rotating roller 72 deposit the dough product 200b on a second belt 70, with the embossed side contacting the belt. A hopper 82 oscillated on rocker arms (84) (Fig. 8, not reproduced) by a cylinder (90) ejects a filling such as jelly on to the passing dough product 200c (Fig. 1), which is simultaneously being moved closer to the hopper nozzle during ejection by a roller (126) (Fig. 3, not reproduced) under the belt 70. The speed of actuation of the ejection is alterable by a variable drive and interchangeable gear wheels. A roller 132 mounted on a pendulum arm, and a nosing bar 190 fold the dough products 200c in half. The uncooked pasties 200d are then conveyed by a steel belt 196 into an oven 199. The belts are scraped clean before receiving fresh products. Gear chains are described (see Figs. 3-7, not reproduced) for controlling the operation. A plurality of pasties can be made simultaneously, or alternatively biscuits, pastries, cakes can be topped with icing but not folded. The oven 199 may be replaced by a freezer. If required, belt 42 may be adjusted in position to take the dough products 200a from the die roller 22 with the embossed side exposed, and to carry the products right way up (see dotted in Fig. 2, not reproduced).

Class 146(3) A cosmetic pencil comprises a barrel 1, a rear cap 8 having a plug 9 secured therein, a stem 10 extending forwards from the centre of the plug, a spiral crayon feed member 15 disposed in the barrel, a longitudinally extending recess 23 at the rear end of the feed member, a key 24 extending forwards from the plug 9 adjacent to the stem 10 which key enters the recess 23 and connects the feed member 15 to the cap 8 for rotation therewith, there being an annular recess 6 adjacent to the rear end of the barrel and an annular rib 7 in the cap 8 which snaps into the recess 6 and permits rotation of the cap relative to the barrel, a crayon carrier 16 rotatably mounted in the spiral feed member 15, and a colouring crayon (not shown) mounted in the carrier 16. The barrel 1 is composed of a synthetic plastic material, e.g. butyrate, and the cap 8 and feed member 15 consist of a yieldable metal, e.g. brass. The plug 9 and stem 10 are a one-piece zinc diecasting. The carrier 16 has a brass tubular portion 25 carrying a lateral lug 26 and into which the rear end of the crayon is frictionally secured, and a zinc, die-cast ejector rod slidable within the tube 25 and carrying an integral lateral lug 28 which projects through a longitudinal slot 29 in the tube 25. In use the lugs 26, 28 are engaged in adjacent convolutions of the helical slot in the feed member 15 and also in a longitudinal groove 18 in the barrel so that when the cap 8 and feed member 15 are rotated the lead is advanced or retracted. When the lug 26 reaches the front end of the groove 18 further rotation of the cap 8 causes the lug 28 to advance to the front end of the slot 29 so that the end of the crayon held in the tube 25 is ejected. The feed-member 15 is slightly bowed so that it frictionally grips the inner wall of the barrel and resists accidental displacement.

Title: Refrigeration system
IPC: A47F3/04
Filed: 1961-06-22
Abstract: 910,551. Refrigerators. HUSSMANN REFRIGERATOR CO. June 22, 1961 [July 15, 1960], No. 22616/61. Class 29. A refrigerator is provided with alternately operable air-cooling and moving means. In a refrigerator cabinet of the open front display type having a storage space 29, air is extracted from the said space through ducts 74 and 75 containing evaporators 66, 67 and fans 64, 65 and the evaporator and fan in each duct are alternately operable, defrosting of each evaporator being effected during its appropriate inoperative period. Cooled air from the duct containing the operative fan and evaporator is supplied to a rear duct 40 and thence to the storage compartment while a small amount of air flows in a reverse direction through the duct containing the inoperative fan and evaporator. This reverse air flow meets and joins the main air flow into the operative duct at the entrance to the ducts 74 and 75 so that excess moisture in the vicinity of the inoperative evaporator is removed and deposited on the operative evaporator. The arrangement ensures that moist air is not supplied to the storage space when the previously inoperative fan and evaporator are started, after defrosting of the latter. In the modifications of Figs. 3, 4, 5 and 6 (not shown), the duct may be shaped to form heat traps in the vicinity of the evaporators which may be placed in staggered relationship as may the fans, and master fans may be placed at the base of the rear duct 40. In Fig. 7 (not shown), the invention is applied to an open-front display case having a larger rear refrigerated storage space. Centrifugal blowers may be used in place of the propeller type fans and electric heaters and drainage channels are provided for depositing, the heating means only being operated after an extended evaporator idling period.

Title: Improvements in or relating to power-assisted steering mechanisms for road vehicles
Inventor: EDGE STANLEY HOWARD
IPC: B62D5/06
Filed: 1953-08-17
Abstract: 759,163. Vehicle power steering. CLAYTON DEWANDRE CO., Ltd. Aug. 5, 1954 [Aug. 17, 1953], No. 22633/53. Class 79 (5). In an hydraulic power steering mechanism for road vehicles, the coaxial sun wheels 36 of a differential gear are connected, respectively, to the lower end of the steering wheel column (not shown) and to the upper end of a shaft 35 which is connected through the usual worm and nut gearing to a drop-arm. The planet pinions 37 can rotate on a shaft 38 of which one end engages in a recess in a transversely-movable valve-carrier shaft 19, and rotation of the planet carrier with the shaft 38 causes actuation of the valve device on shaft 19 to control the servomotor. Spring-pressed into recesses at the ends of shaft 19 are valve heads 20 each of which acts as a shuttle valve to control the flow of hydraulic liquid between an inlet 27, a sump connection 25, 8, and a port (not shown) leading from the chamber 16 between the valve seats to one end of a double-acting piston-andcylinder servomotor connected between the chassis and the drop-arm. In the straightrunning position, the valves are centralized and there is a constant circulation between the pump, the servomotor, and the sump. After the valves have been moved to initiate a steering action, the resultant movement of the servomotor is fed back through the differential gear to re-centralize the valves. The valve surfaces are so dimensioned that movement of the valves away from the centralized position causes the pressure build-up to react back on the valves and, through the differential gear, on to the steering-wheel. Movement of the planet carrier takes place against the force of centralizing springs 44. The double-acting servomotor may be replaced by twin single-acting servomotors. A relief valve is provided in a by-pass between the pressure inlet and the sump connection of the valve device. A non-return valve in a further by-pass between the sump and pressureinlet connections permits of direct manual steering on failure of the hydraulic supply.

Abstract: 901,888. Controlling aircraft. ROLLSROYCE Ltd., and LUCAS (INDUSTRIES) Ltd., JOSEPH. June 18, 1959 [July 15, 1958], No. 22728/58. Class 4. An aircraft engine control mechanism comprises a lever having successive ranges of movement and connected to a number of devices to be operated in sequence through a cam arrangement comprising an arm rocked by the lever and a separate rocking element for each device, each rocking lever having a cam slot engaged by a corresponding roller on the arm, each cam slot having a portion or portions which, when engaged by the roller are centred on the axis about which the arm rocks, and having an operating portion which, when traversed by the roller causes rocking of its element and operation of the associated device, the operating portions of the cam slots being traversed by their rollers in succession to cause successive operation of the devices as the lever moves through successive ranges. In the Figure, the lever 13 has three ranges of movement 15, 16 and 17, and is connected by link 18 to the lever 10 of a propeller feathering unit 10a. In the position shown of lever 13, the propeller is feathered. On moving lever 13 through the range 15, to position 13a, lever 10 actuates unit 10a to unfeather the propeller, and unit 10a is such that further movement of lever 13 into ranges 16 and 17 does not further actuate unit 10a, the propeller merely remaining unfeathered. Lever 13 is also connected through links 18, 19, crank arm 20, and shaft 21, to an arm 23 bearing rollers 24, 26, 27 working in slots in sectors 28, (rollers 24, 26) and 30 (roller 27) on concentric shafts 29, 31. Shaft 29 is connected by arm 32 and link 34 to the lever 35 of a fuel shut-off cork 11. Shaft 31 is connected by arm 33 and link 36 to the arm 37 of a fuel trim control 12. The slots in sectors 28, 30 are such that during movement of lever 13 in range 15, neither sector is moved. During movement of the lever in range 16, only sector 28 is moved, and during movement in range 17, only sector 30 is moved. Movement of the lever from position 13a to 13b turns on the fuel cock 11. The lever can then be placed in a desired fuel trim position in range 17. To feather the engine, lever 13 is first moved to position 13a, shutting off the fuel cock, and then moved to the position shown, to operate the feathering unit 10a.
