Title: An automatic device for replacing full bobbins by empty spools in a yarn-winding system
IPC: B65H54/26
Filed: 1980-01-17
Abstract: Automatic doffing and replacement of bobbins by empty spools is carried out without any interruption of spinning operations by means of a device comprising a carriage and photoelectric means for detecting a full bobbin as the carriage passes in front of a winding unit and for actuating means locking the carriage in position. The yarn is cut between the bobbin and the delivery roller and the delivery end is retained. The bobbin guiding arms are lifted and opened-out for discharging the full bobbin and receiving an empty spool taken from a magazine, then lowered until the spool rests on the yarn-winding roller, and a yarn reserve is formed on the spool by means of a suction nozzle, all operations being controlled by a programmer mounted on the carriage.

Title: Fluid Powered Presses
IPC: B30B15/16
Filed: 1980-02-21
Abstract: A press has an output piston 18 responsive to an intensified hydraulic pressure in a chamber 17, resulting from downward movement of a pneumatically operated piston 10. The output piston 18 is also movable by a pneumatically operated piston 34, to provide a relatively rapid, low force, approach stroke. The effective area of the piston 34 is sufficient to overcome the force applied by return springs 28 for the output piston 18. <IMAGE>

Title: Improvements in package strapping apparatus
IPC: B26D5/18
Filed: 1980-07-25
Abstract: In a package strapping tool of the "pusher-bar" type which does not have a fixed base plate under the overlapping strapping portions to be joined, the joint is by interengaging incisions made in the strapping by a punch 104 vertically movable by a pneumatic ram assembly 27 into and out of engagement with a die element 105. The die element is provided on pivoted jaws 106 which are swung apart to allow the strapping to be inserted and then swung together under the strapping. The ram assembly 27 drives a toothed rack (not shown) in engagement with a gear sector having an arm 42 pivoted to a link 102 which together form a toggle linkage for moving the punch 104. The rack has projections 111 in which are angled slots 110 engaged by pins 109 on the jaws 106. On the initial downward movement of the rack the jaws 106 are swung together by the action of the angled ends of the slots 110. The pins 109 then enter extents 112 of the slots parallel to the direction of motion of the projections 111 so locking the jaws in their closed position while the punch 104 moves towards the die elements 105. Finally pins 117 moving with the punch 104 engage holes 118 in the jaws 106 preventing the jaws from separating under and then swung together under punch pressure. <IMAGE>
Patent GB-2075395-A (GB)
Title: Air cushion snubber apparatus and method
IPC: B21D24/02
Filed: 1980-12-01
Abstract: A floating piston 62 is mounted within the air cushion 64, 66, 68 in a press and defines a snubbing chamber 70. As the air cushion returns to its top stroke position after yieldably deforming to cushion a member within the forming press, a movable piston 56 within the air cushion contacts the floating piston 62, forcing it to move in the direction reducing the volume of the snubbing chamber. A check valve 80 is provided between a cushion chamber and the snubbing chamber which maintains the pressure in the snubbing chamber at a minimum equivalent to the pressure in the cushion chamber. As the volume of the snubbing chamber is reduced, the air trapped within is compressed to slow the motion of the air cushion. A snubber valve 78 communicates with the snubbing chamber and maintained in a closed position by the air pressure within the cushion chamber. During the snubbing action, when the air pressure within the snubbing chamber reaches a predetermined value, the snubber valve is opened permitting the air from the snubber chamber to escape through the valve to the surrounding atmosphere. <IMAGE>

Title: Control Valve Device for I.C. Engine Exhaust Gas Recirculation
IPC: F02M26/58
Filed: 1981-11-27
Abstract: The position of the recirculation valve 11 is determined by a pair of spring-loaded diaphragms 18 and 20 subject in the chamber 19 between them to the suction downstream of a carburettor throttle valve and on their other sides to atmospheric pressure. The initial loading of the diaphragm 18 by a spring 31 is set by a sleeve 26 carried by the diaphragm 20 and the compression of a spring 32, biasing the diaphragm 20, at which the valve stem 13 is engaged by the screw 27 carried by the diaphragm 20 to close the valve 11 is set by screw adjustment. In operation, at high idling suction the diaphragm 20 causes the valve 11 to close via the screw 27, at low suction suction corresponding to high engine output the spring 31 biases the valve closed and at intermediate suctions the valve opening will be dependent upon the diaphragm areas and spring forces. <IMAGE>

Title: Igniters for internal combustion engines
IPC: H01T13/52
Filed: 1982-01-18
Abstract: A ceramic insulator (17) containing a substantial proportion of silicon nitride is disposed annularly within the shell (13) of the igniter so that spark discharge occurs along a surface of the silicon nitride insulator (17) adjacent the spark gap between a center electrode (14) and a ground electrode (18). An igniter having such a silicon nitride insulator is particularly adapted for service under conditions of severe thermal, mechanical, and electrical stress, in an engine having a high voltage, (e.g., 10,000 volts or more), high energy (e.g., up to 20 joules) ignition system. Use of silicon nitride as an insulating material in such igniters eliminates health hazards associated with toxic beryllium oxide insulators previously used, while producing an insulating surface far more durable than one made of alumina. <IMAGE>

Title: Control system and method for DC pulse modulated arc welding
IPC: B23K9/067
Filed: 1982-03-11
Abstract: In a method of pulsed direct current arc welding with a feedback control system (2), the duty cycle of constant amplitude current pulses supplied by a power supply is controlled in response to resistance sensed at an arc gap (3) to maintain a constant time-averaged power flow to work pieces (1) which are welded. The feedback control system (2) includes a voltage sensor (7), a high-low regulator (8), and a duty cycle signal generator (9). This pulsed DC arc welding is especially useful with a type of pulsed DC arc welding wherein the ratio of peak current to maintenance current is maintained at a selected high value and the current is cycled in a time duration whereby oxides on the surface of the work pieces are dissipated when making the weld. Also, a control system is disclosed for automatically adjusting the width of current pulses supplied at an arc gap by a pulsed DC arc welding system power supply, to control power flow to work pieces at the arc gap according to a predetermined program. <IMAGE>

Title: Encapsulated living tissue
Inventor: LIM FRANKLIN
IPC: A61K35/39
Filed: 1982-09-29
Abstract: An encapsulating process includes suspending finely divided chemically active or biologically active material or living tissue in an aqueous medium in which a gellable gum is dissolved. The aqueous suspension is then passed through a vibrating capillary tube (18) mounted centrally in the vortex (14) of a rapidly stirred solution containing a gel-producing solute. The suspension emerges from tube (18) as droplets which on contact with the stirred solution gel to form shape-retaining capsules enclosing the said material. Subsequently the capsules are treated to form a permanent membrane coat which may be semi-permeable, and optionally thereafter the gel may be reliquefied. The process can be used to encapsulate e.g. islets of Langerhans or liver tissue with a physiologically compatible culture medium to produce an artificial pancreas or a body fluid detoxifying system which may be introduced by injection into the body. The permanent membrane can be engineered to pass nutrients, amino acids, oxygen and hormones but to block bacteria, lymphocytes and large molecules such as immunoglobulins. An artificial animal organ may be made which incorporates the capsules. <IMAGE>
