Title: Process and apparatus for producing a twisted yarn
Inventor: DERICHS JOSEF DIPL ING
IPC: D01H4/16
Filed: 1984-06-07
Abstract: The spinning fibres are drawn to a fibre mass per unit length appropriate for the particular yarn and are parallelised at the delivery point (16), and are then transported as a closed fibre composite (54) to the yarn-forming point (8), physical forces of attraction taking effect on the fibres along the transport path and causing the spinning fibres to be laid against one another. Directly in front of the yarn-forming point (8), the fibre composite is brought out of the effect of the physical forces of attraction and is exposed, instead, to physical forces of repulsion which fan open the fibre composite and spread individual fibres apart from one another, detach them from the fibre composite and feed them to the yarn-forming point (8). The transport of the fibre composite (54) is ensured, for example, by a rotatable fibre-composite conveyor (26). The apparatus is suitable especially for friction-spinning machines (1) and allows feeding from the drawing unit. <IMAGE>
Patent DE-3429071-A1 (DE)
Inventor: CZECH GUENTHER
IPC: G02C1/02
Filed: 1984-08-07
Abstract: This invention relates to spectacles in which are spectacle lens is connected to an individual component, for example a flange, by means of a fatening device. In the spectacle lens the two ends of a borehole are expanded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion. In addition, the flange has two further protrusions supporting themselves on the border of the spectacle lens, so that a four-point anchoring of the flange secured by the pin against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa. A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping surfaces for the connecting element and first protrusion, but the borehole widening.

Title: Windscreen wiper system for motor vehicles
Inventor: HEUWIESER ERWIN DIPL ING
IPC: B60S1/48
Filed: 1984-11-15
Abstract: In a windscreen wiper system in which one motor is provided per wiper, the motors must be synchronised in order to avoid the wiper blades colliding. This takes place as follows: each wiper and each motor (15, 16) is assigned in each case one signal generator (7 to 20). The wiper signal generator (19, 20) generates a reference signal when the associated wiper (21, 22) assumes a specific position in the wiping field. The motor signal generator (17, 18) produces a rotary angle pulse each time the motor rotates. A control circuit ( mu C) counts the rotary angle pulses which follow and are associated with a reference signal, compares the two counting totals with one another and slows down or temporarily stops one of the motors (15, 16) when the difference between the counting totals exceeds a predetermined value. Such a control, including the pulse generation, can be carried out fully electronically; the expenditure in terms of circuitry is relatively low. <IMAGE>

Title: Propellant for actuating a device for closing a blood vessel
Inventor: LANGE WOLFGANG PROF DR
IPC: A61B17/12
Filed: 1985-02-14
Abstract: The invention relates to a propellant for actuating a device for closing a blood vessel in the animal body. The intention of the invention is that, after activation of the propellant, the pressure built up by the propellant in the hollow body system belonging to the device is essentially maintained permanently. The pressure increase is to be achieved without reducing the volume of the hollow body system. This is achieved by an exothermically reacting mixture which, as the reaction takes place, brings about a pressure increase in the hollow body system and keeps the maximum pressure virtually constant. Used as propellant is a winemaker's yeast/sugar mixture with the addition of a liquid, a mixture of KClO3 and C6H12O6 with the addition of heat, or else an oxyhydrogen gas mixture obtained from a sodium chloride solution by electrolysis with electrical ignition.

Title: Safety screw
Inventor: SCHIEHLEN ERNST-DIETER
IPC: F16B37/14
Filed: 1985-03-16
Abstract: By means of a safety screw described by us a fastening element is to be specified which is easy to handle, prevents loosening and permits cost-effective production. This is possible by means of the screw described by us. The chamfered surfaces provide no grip for tools. Due to the design of the screw head and of the large bearing surfaces, a simple bore in the parts to be fastened is sufficient. The receiving point for tools can be sealed by means of a hardened filling piece and thus provides protection against unauthorised drilling. The screws are principally used in safety engineering, e.g. for fastening grilles. Optimum protection is ensured by means of this safety screw.

Patent DE-3521214-A1 (DE)
Title: Biothermal room climate
Inventor: GEIER-HENNINGER KURT
IPC: F24F7/00
Filed: 1985-06-13
Abstract: The biothermal room climate would be particularly recommended everywhere where people have to work the whole day year after year. The great advantage of this system is that the thermal lift of the warm air, on flowing over the evaporation surface, deposits dust particles, which are carried along from the bottom to the top, on the ribs. The circulating air consequently cleans itself. A further plus point is the individual room temperature, each room can be controlled individually in its cooling capacity via a room thermostat. The preservation of the air humidity is guaranteed and can if applicable also be improved. Furthermore, with a switchable cooling circuit, the evaporator pipes can be used as condenser pipes for heating the rooms on cooler days in the interseasonal period.
Patent DE-3522209-A1 (DE)
Title: Combined grilling device
Inventor: COZZIO SEVERIN
IPC: A47J37/06
Filed: 1985-06-21
Abstract: In the grilling compartment (16) of the grilling device which can be heated by town gas, natural gas and liquid gas, there are mounted an upper heating device (2) which is adjustable upwards and downwards and two lower fixed heating devices (3) which can be switched independently of one another, a heating grid (5) being mounted directly at the upper end of the gas nozzles (4), as a result of which the gas flowing out produces a bed of flames. The upper heating device (2) serves for grilling and, at the same time, for heating the burner hood (16) as a plate warmer and for operating a raclette grill. The heating device (3) has two functions, it heats the support plate (8) and, due to its dual-function device, also gives off the heat downwards through the heating grid (5) and thus provides two further grilling points. The individually adjustable heating devices allow different meals to be prepared efficiently in a very narrow space, virtually without hindering one another. <IMAGE>

Title: Exhaust turbocharger with dynamic charging performance
Inventor: SCHOPF WALTER
IPC: F02C3/113
Filed: 1986-01-29
Abstract: Exhaust turbochargers, which are becoming increasingly common due to their known advantageous useful effects when used on passenger car internal combustion engines, have the disadvantage that a low (normal) basic engine torque is available at low engine speeds, and that the adjustment of a desired charging ratio, that is the load take-up response, is relatively slow. Nor is the energy contained in the exhaust gas fully utilised in the upper engine power range. The purpose and aim of the concept of the present invention is to overcome these disadvantages. This is achieved in that the rotating turbine base 4 has a centrifugal mass 5 far in excess of the usual, the kinetic energy of which, in brief low-speed phases or in acceleration phases, is fed to the compressor 3 by varying the transmission ratio of a transmission device 2, arranged between turbine and compressor, such as, for example, an infinitely variable transmission or variable speed transmission with torque splitting, so that the power of the compressor can be adjusted spontaneously and to any desired compression ratios. If a variable speed transmission with torque splitting is used, the third path of which is connected to a machine and/or an engine, it is possible, in the event of excess turbine power, to feed energy into a vehicle electrical system, an energy accumulator or to the running gear or, in the low engine-speed range (turbine power deficit) ... energy ...
