Title: Yarn stripping machine - has equipment to remove remainder from cop tube using reserve energy held in springs
Inventor: WIRTZ ULRICH DR ING
IPC: B65H73/00
Filed: 1991-09-23
Abstract: A stripping machine removes yarn ends from spinning tubes, which are mounted on a cop plate. The lifting mechanism which surrounds the yarn remainder is mounted on a frame which rests on springs, releasing potential energy for the force required to separate yarn from the tube. The tube (3) is pref. mounted on a cop plate (2) which has a projection and a vertical stud (5). The yarn remainder (4) is removed by the mechanism (6,7). A conveyor band brings in the plate (2) which is located initially by a magnetic system (17), and then a controlled pneumatic system (31-33) brings a centre down into the top of the tube (3) along the mechanism (43-45) and the tube (37). This locates the tube (3) centrally into the stripper plate (9) mounted on the base (8), which also has spring held blades (14) around the centre, which expand and contract to fit underneath the yarn remainder (4). This is also pneumatically controlled and has a lever mechanism (25-30). The motor (23) drives through a gear arrangement (22), so that the plate (8) and chain (15) can be raised and lowered. On lowering, there is a build up of reserve energy for the upward movement, contained in the pressure exerted against the springs (16). Without having to increase the power from the motor, there is sufficient force for the blades (14) surrounding the yarn remainder (4) on the tube (3) to be lifted off. The ducting (36) is connected to air extn., and as the yarn is drawn off the tube it is carried away. There is a cutter blade movement inside the duct (36). The lift to the plate (8) is repeated to clear the tube (3). ADVANTAGE - The mechanism contains equipment which balances forces, so that the tubes are not damaged in the process, the remainder of the yarn is removed rapidly, and overload is avoided.

Title: Quick-release screw clamp - has nut on spindle which can swivel to allow complete release of clamping segments
Inventor: OTTO ULRICH
IPC: F16L23/10
Filed: 1992-03-30
Abstract: The quick-action clamp has two semicircular segments (3,4) of U-shaped cross-section. They are hinged together at one end, and at the other end are held together by a nut (1) with a knob (7) enabling it to be turned by hand.

Title: Sewing machine fabric slit cutter - has blade movement and pitch adjustment to set length and angle of V-cuts at ends of straight cut
Inventor: KONDO TAKASHI
IPC: D05B37/04
Filed: 1992-07-21
Abstract: The cutting blade system at a sewing machine e.g. for pocket openings, where the ends of a straight cut are extended outwards by angled cuts to form V-shapes at the ends, has a pair of cutting blades below the fabric on a holder. Each blade has a cutting edge at an angle to the geometric movement axis to form the angled cut when the blade is moved upwards. An adjustment sets the swing angle of the blade round its geometric axis and a drive moves each blade up and down on its axis. The length of the angled cuts, at the ends of the straight cut, are set to determine the highest setting for the point of the cutting edge to establish the cutting edge length to be used, when the blade is moved upwards. ADVANTAGE - The length and angular pitch of the angled cuts can be set easily by the user.

Title: Multicircuit safety valve
Inventor: ROENNEFARTH KLAUS
IPC: B60T11/32
Filed: 1993-03-05
Abstract: The intention is to ensure the refilling of the feed circuits of a pneumatic multicircuit brake system, even when one service brake circuit is defective, by means of an air compressor providing a reduced compressed air volume flow. The multicircuit safety valve (10) has two service brake circuits (I, II) and further circuits (III, IV). All circuits (I to IV) are supplied with compressed air from an air compressor (13), each by way of an overflow valve (24.1 to 24.4) with secondary-side influencing. The overflow valves (24.1, 24.2) assigned to the service brake circuits (I, II) are each bypassed by a bypass line. A rocker piston (29), controllable by the pressure in the service brake circuits (I, II), controls non-return valves (39.1, 39.2) arranged in the bypass lines. The non-return valves (39.1, 39.2) act on pins (46.1, 46.2) arranged in the rocker piston (29) and restricting the rate of air flow through the bypass lines. The multicircuit safety valve (10) can be used, in particular, in motor vehicles (Fig. 1). <IMAGE>
Patent DE-4314629-A1 (DE)
Inventor: BASIL OBRIST
IPC: B23Q3/00
Filed: 1993-05-04
Abstract: The clamping device has a base (1), to be fixed to the workplace of the processing machine, and a work carrier (2) which can be mounted and clamped on the base. Orientation elements (13 - 20), interacting in pairs, at the base and at the work carrier orientate the work carrier (2) in three coordinate axes (X, Y, Z) perpendicular to one another and at the correct angle onto the base (1). There are three linear pairs (15, 16; 17, 18; 19, 20) of orientation elements for establishing the position in a coordinate plane (X-Y). Two of them are arranged at two opposite end areas of the device and together establish the position in the coordinate axis (Y) running transversely to the connecting line of the same. The third pair of orientation elements is arranged in the centre between the other two and establishes the position in the other coordinate axis (X). To clamp the work carrier in place, two clamping members (40, 41) are provided on the base (1). The clamping members (40, 41) are each arranged between an end linear pair of orientation elements and the centre linear pair of orientation elements. In this way, a compact type of construction of the clamping device and increased loading capacity of the same can be achieved with a minimum of linear pairs of orientation elements. <IMAGE>

Filed: 1993-05-05
Abstract: The connector has rigid casing (1) of insulating material enclosing a fixed socket (3) for electrical connection to the contact of the sparking plug (14) around which it is fitted. An elastomeric sleeve (2) covering only a portion of the length of the casing has a ribbed forward section (18) which fits tightly around the insulator (13) of the plug.The ignition cable is taken through a duct (6) along the axis of the casing. The sleeve can be stretched sufficiently for fitting over the casing but grips the latter too tightly to allow relative rotation.

There can be a truncated-cone contact face between it and the vessel (1, 2), and whose angle is such that there is no self-locking effect between them. ADVANTAGE - The fixing device for the cover needs only to support its weight, little prestressing of the joint being required.

Abstract: A fastener for items of jewellery for the ends of a wire-like or cord-like jewellery carrier, for example a necklace wire, a core wrapped by metal wire, a string of pearls or the like, having ends which can be joined together, at least one end being thickened. Known fasteners of the generic type for items of jewellery are either complicated to handle, complex to produce, or can easily be opened inadvertently when wearing them. The object of the invention is to provide a fastener which is simple to handle, simple to produce and can be fastened securely. The fastener consists of a top part 2.0 which has a latch 2.1 and a bottom part 1.0 which is connected to a sleeve interlock 3.1. An elastic element presses the latch 2.1 against the sleeve interlock 3.1. The fastener is now closed because the removable thickened ends 4.1 do not fit between the latch and the interlock. When the top part and the bottom part are squeezed together, the latch and interlock move apart, the removable thickened end can be introduced and pulled out. The top part and bottom part are held together by the interlock and latch. A fastener for items of jewellery for a jewellery carrier having thickened ends which can be joined together. <IMAGE>
