Patent DE-3238252-A1 (DE)
Title: Spinning process
Inventor: HEINTSCHEL-HEINEGG EGBERT VON
IPC: D02G3/28
Filed: 1982-10-15
Abstract: The invention relates to a spinning process in which a slubbing of staple fibre is drafted with the aid of a drafting arrangement and then passed through a thread guide to a spindle and consists in supplying at least one further strand at the thread guide, so that the drafted slubbing and the at least one further strand are united in a combined spinning and twisting process. This has the decisive advantage that, even if the twist level of the drafted slubbing is low, the at least one further strand ensures a strength level which is sufficient for processing the ready-produced yarn. This yarn is suitable in particular for producing tufted material.

Title: Device for processing modelling waxes
Inventor: WINTER HEINZ
IPC: A61C13/00
Filed: 1983-04-22
Abstract: A handpiece for application of wax has a storage chamber (6) for liquid wax (11) in its head region, the chamber being electrically heatable and in flow connection via an inflow channel (12) to an exchangeable modelling tip (4). The metering device provided for application of wax is a pin (18) which is forced by a restoring spring (20) into a position of rest determined by a stop, in which position of rest a shoulder (19) terminates a passage opening (16) for the pin (18) in the circumferential wall (15) of the storage container (6). In the depressed position of the pin (18) the shoulder (19) is lifted off the passage opening (16) and either air is supplied to the storage chamber (6) on the outer circumference of the pin (18), so that the liquid wax (11) can run out at the modelling tip (4) under the action of gravity, or else the air cushion (17) is subjected to pressure above the liquid wax (11), so that the wax is discharged due to overpressure. The pin (18) is diametrically opposite the modelling tip (4), which points downwards during operation, in a region of the storage chamber (6) in which there is no wax (11) in the operative position of the handpiece and in which pressure can be simply exerted with the index finger in an ergonomically favourable way. <IMAGE>

Title: Energy-saving cooking vessel for use on an open flame
Inventor: NUSSER ALBAN
IPC: A47J36/36
Filed: 1983-11-04
Abstract: An energy-saving cooking vessel for use on an open flame has an outer vessel which encloses the combustion gases and in which an opening in its bottom terminates with the gas burner or the burner head of a vaporising burner in such a way that not substantially more than the quantity of combustion air required for complete combustion can reach the flame. The annular space and bottom space enclosed between the cooking vessel and the outer vessel are of such narrow construction that the combustion gases are swirled. The outer vessel is of heat-insulating construction, whereas the cooking vessel consists of a material with good heat-conducting properties and has on its outside a lamellated surface and/or heat exchanging ribs. The energy-saving cooking vessel can be taken apart for cleaning purposes. For mobile use, for saving weight and better transportability, the outer vessel is formed from multi-layered, flexible and heat-resistant fabric which is stretched removably over a frame which can be clamped together with removably hooked-in support legs. After separation at a separation point, the outer vessel can be spread flat for easier transportation. <IMAGE>

Title: Solid-state image pick-up transducer
Inventor: YUSA ATSUSHI
IPC: H04N5/355
Filed: 1983-12-14
Abstract: A solid-state image pick-up transducer exhibits a number of SIT image sensors which are arranged in a matrix form and each of which exhibits a drain region in the form of an n<+> substrate (8) which is connected to earth potential, a channel region (10) in the form of an epitaxially grown n-type layer on the substrate, an annular p<+> gate region (11) on the surface of the epitaxial layer and an n<+> source region (13) which is formed in a part of the surface of the epitaxial layer and is surrounded by the annular gate region. Furthermore, a p<+> overflow drain region (9) is formed in the surface of the substrate below the gate region. The time interval during which photocurrent carriers, that is to say electrons, flow into the gate region (11) and are stored there, can be optionally controlled by setting the duration of a shutter control signal which is applied with positive voltage to the overflow drain region (9). In this manner, an electronic shutter function is achieved. <IMAGE>

Title: Equipment for and method of picking up and rescuing a person drifting in the water
Inventor: VITUS WOLFGANG
IPC: B63C9/26
Filed: 1983-12-23
Abstract: The hitherto known lifesaving equipment needs to be put on or fastened in the water by the casualty or a second person as an assistant in the water, or the casualty was pulled out of the water with the applied lifesaving equipment in a hanging, largely perpendicular position putting the circulation at risk. The invention of the horizontally mounted strap-carrying system provides lifesaving equipment which is movable on the deck rail and with which, for example by means of the boat hook, the rescue basket can be slipped over the casualty from the vessel,     1.) without a second person having to help in the water, 2.) without the casualty having to help, for example in the event of exhaustion, 3.) without the casualty, who possibly has greatly weakened circulation due to exposure, having to be pulled perpendiculary out of the water and thereby suffering a circulation breakdown.   The equipment is light and flexible, can be folded or twisted together, unfolds automatically, moves the carrying strap into the correct position in the process, can be manipulated (slipped over) from the vessel and can be kept ready packed together at the side rail even on smaller vessels.

Title: Belt duct of an automatic weapon having a barrel
Inventor: BREMER CLEMENS ING GRAD
IPC: F41A9/57
Filed: 1984-02-03
Abstract: A belt duct 10, which varies its track flexibly and is known per se, of an automatic weapon having a barrel contains supporting elements 4 in order to increase its range of applications in the case of inwardly curved belt duct tracks for separate support of the belt links 5. On belt duct tracks which are curved in such a manner, and in the case of high masses which are to be accelerated in a short time and consist of cartridges 18 and belt links 5, the supporting elements 4 prevent the belt links 5 being released from the cartridges 18 as a result of the considerably radially inwardly directed force components. The specifically light supporting element 4, which consists of a thermoplastic synthetic material or a suitable metal, can easily be installed as a plug-on clamping piece and, as a result of its trapezoidal cross-sectional surface, forms a closed sliding surface 8 even in the event of sharp curvature. The supporting element 4 is secured against rotation by means of steps 15 on both sides on the ends 14, which are supported on the frame segments 2, 3 of the belt duct 10. The supporting element 4 can also be designed as a roller which can rotate, in a manner which is not shown. <IMAGE>

Patent DE-3408184-A1 (DE)
Title: Device for improving splicing devices
Inventor: BECKER KLAUS
IPC: D02J3/02
Filed: 1984-03-06
Abstract: In the so-called splicing of yarns to form knot-free connections of two yarns (10, 20), it is essential that the yarn ends (11) terminate in pronounced fibre tufts, so that the fibres can loop closely round one another within the splice. In order to form such fibre tufts from the yarns (10, 20), the yarns are laid under slight tensile stress over at least one rotor (13; 16). Located on this rotor are a number of edges (15; 18) which peel fibres off from the fibre composite and thus at the same time weaken the yarn cross-section increasingly until the yarn ends (11, 12) slide apart from one another. The rotor (13) either can be designed as a rotating disc with teeth projecting in the axial direction, or can be designed as a hemispherical body (16) with worked-in grooves (17, 19). In the latter case, two yarns can be laid simultaneously over the hemispherical dome and be severed to form the fibre tuft.

Title: Fuel injection device on an internal combustion engine
Inventor: KAPPLER GORM
IPC: F02M45/00
Filed: 1984-05-23
Abstract: In a fuel injection device a conventional injection valve is connected by way of a pressure line to an injection pump. The pump pressure chamber of the latter is connected to the fuel receiving chamber by way of at least one intake bore and at least one outlet bore, and, during the delivery stroke, the pump piston first of all, with its upper control edge determining the start of injection, closes off the intake bore cross section, then the outlet bore cross section, and later with its bottom control edge re-opens the intake bore cross section in order to terminate the injection. In addition the mouth cross-sectional area of each outlet bore on the fuel receiving chamber side can be adjusted to any value between "fully open" and "fully closed" by variable covering by means of the closure member of a control slide valve. The said control slide valve is connected to an adjusting device and can be actuated by means of this in such a way that in relation to the injection characteristic which exists with the mouth cross section closed, by opening and deliberate adjustment of the effective mouth cross-sectional area of the outlet bore the quantity of fuel flowing out of the pump pressure chamber into the fuel receiving chamber during the delivery stroke of the pump piston and thereby the pressure build-up in the pump pressure chamber can be purposely influenced in order to retard the start of injection with or without any division of the injection into a pre-injection and a main injection.
