Title: Belt type wrapping apparatus
IPC: B21C47/06
Filed: 1961-08-04
Abstract: 911,940. Winding and reeling. BLAW-KNOX ACO. ug. 4, 1961 [Aug. 9, 1960], No. 28381/61. Class 83 (4). Belt wrapping apparatus for coiling sheet material on a rotatable mandrel to form a coil comprises a belt adapted to partially encircle said mandrel during the coiling operation and means to support the belt in contact with a coil formed on said mandrel so that the total length of belt in contact with the coil increases as the coil diameter substantially increases. Strip S fed over a pivoted table 9 is wrapped around a rotated mandrel 1 by belts 3 and 4 running over idler rolls carried on arms pivoted in housings 5, 6 which are moved by hydraulic means to positions adjacent the mandrel 1. The belt 3 passes over idler rolls 21, 23 on opposite ends of a lever 18, pivoted at 16 to the housing 5 and urged by spring means 38 which tend to move the roll 19 towards the mandrel 1, and over idler rolls 43, 45 on opposite ends of a lever 41 pivoted at 17 to the housing 5 and urged by spring means 63 (not shown). The rolls 23, 45 are spring-mounted in their levers 18, 41 and the belt is tensioned by a spring-urged roll 65. Stop means limit the inward movement of the levers 18, 41. The belt 4 passes over a similar arrangement of rolls on levers pivoted in the housing 6. As a coil builds up on the mandrel 1 the levers 18, 41 pivot, moving the rolls 21, 43 apart so that the length of belt 3 contacting the coil between the rolls 21, 43 increases with increasing coil diameter. Preferably also the included angle A of belt contact increases with increasing coil chambers. The belt 4 similarly contacts the coil over an increasing length. When the coil reaches a predetermined size a member 81 on the arm 18 actuates a switch 83 to stop rotation of the mandrel. The front end of the table 9 rests on the coil and rises as the coil diameter increases. The belts may be ridged and the rolls centrally grooved to engage the ridge. A plurality of belts arranged side by side may be used. The apparatus may coil successive short lengths cut from the tail or leading end of coiled strip.

Title: Device for effecting temporary sterilisation
IPC: A61F6/20
Filed: 1973-06-14
Abstract: 1430316 Sterilization devices RICHARD WOLF GmbH 14 June 1973 [9 Jan 1973] 28442/73 Heading A5R A device for effecting temporary sterilization by binding a Fallopian tube, comprises an elongated barrel 1. an implement 2 at the distal end thereof, operable from the proximal end, the implement 2 consisting of a pair of grips 3, 4, with curved arms 3a, 4a arranged to surround said tube, each grip having a longitudinal passage 5 within which passes a binding element (not shown), the barrel 1 being dimensioned to permit insertion through a cannula, the arms 3a, 4a being normally closed, and each forming an approximate semi-circle, from which the grips extend to lie parallel to each other within barrel 1. The binding element is drawn through passage 5 from the proximal end of tubular grips 3, 4, and through the closed arms 3a, 4a, and terminates back at the proximal end of grips 3 and 4. The arms 3a and 4a may rest flat against one another or may partly imterengage, and are preset to exert an outwardly directed pressure. Barrel 1 bears against the sloping faces on arms 3a, 4a, so that movement of barrel 1 away from the arms permits the grips to open, and movement in the opposite direction causes them to close, the grips 3, 4, being fixed in tube 7 which slides coaxially in barrel 1. Spring handle 8 connected between barrel 1 and tube 7 holds the grips normally shut but controls their opening from the proximal end. A Fallopian tube is surrounded by the grips and a thread is drawn through passage 5 by a probe, via tube 3, arms 3a, 4a and back via tube 4. The device is withdrawn leaving the thread, looped round the Fallopian tube, to be tightened. In a modification the arms 3a, 4a may be dished in crosssection, the concavities facing one another, or facing away from each other. Further, the passage 5 may begin and end in the side of tube 7 rather than at the proximal end. The arms 3a, 4a may not rest fully closed, in which case the thread passage would be interrupted. It is also possible to use a separate binding element in each of the tubes forming passage 5, with a portion of the thread projecting from each arm so that they can be connected by fusion, etc. When the grips are closed, thereby producing a continuous thread.

Abstract: 832,417. Rotary dashpots. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. Sept. 10, 1957 [Dec. 21, 1956], No. 28460/57. Class 108(3) In a hydraulic damping device segments 30, 30a, 30b, 30c, Fig. 3, serve as vanes for the displacement of damping liquid. A disc 24 fits over the vanes 30-30c and slots 26 permit some rotation of the disc relative to a plate 18. Blocks 20, 20a, 20b, 20c are mounted to slide between lower grooves 23 in the disc 24 and upper grooves 42 in a member 38 and function as valves or gates in the damping system. In operation liquid is pumped from one side of each of gates 20-20c to the other through passages 70, Fig. 1, by the vanes 30-30c. The size of passages 70 is thermostatically controlled by the action of a flexible metal bellows 62 which moves a plunger 52 up and down in response to temperature changes in the damping liquid. An edge 59 of the plunger 52 thus either pushes on cam faces 27 of blocks 20-20c to move the blocks outwards or allows the blocks to move inwards urged by springs 25. Cam faces 27 are profiled to provide linear damping characteristics. A thermostat may be used in place of flexible bellows 62.

Title: Improvements relating to the generation of combustion products under pressure
IPC: F02G3/00
Filed: 1920-10-12
Abstract: 171,863. Maccallum, P. F. Oct. 12, 1920. Generating combustion products under pressure.- Solid fuel is burnt for power purposes by moving a mass of ignited fuel through an enclosed charge of air &c. thus causing combustion and producing pressure gases which are delivered to the engine cylinder. The apparatus may be vertical as shown, or inclined, or horizontal. A movable firebox b containing the ignited fuel is reciprocated in a chamber a connected at d with the power cylinder. In operation, during the compression stroke of the engine, the fire-box is in an " inert " position where combustion is a minimum, say above the passage d. The box is then rapidly moved through the charge of compressed air or other gas in the chamber a causing combustion of the fuel, and the pressure gases resulting escape at d to the power cylinder. Exhaust then occurs and the fire-box is returned to its " inert " position ready for a fresh charge of air &c. Dispersal of the fuel is prevented by the downwardly inclined members k, l and for the same purpose the box may be rotated in order to apply centrifugal force to the fuel. Water in the base of the chamber a serves to cool the operating rod c and to receive ashes &c. Scavenging may be assisted by additional air admitted through a non-return valve near the surface of the cooling water. In the horizontal form, the operating-rod is completely submerged in the cooling-water and the fire-box has a solid bottom and grated ends. Fuel feed is effected either by a non-return valve and apparatus such as described in Specification 18242/00, [Class 7, Air and gas engines], or by momentarily arresting the fire-box and feeding through a door. Glazed sight-holes and extra air inlet valves may be provided.
