Title: I.C. engine fuel injection system - has air flow dependent metering unit with speed dependent return spring
Inventor: MEISSNER KURT DIPL-ING
IPC: F02M69/48
Filed: 1973-08-28
Abstract: The metering unit consists of a plate pivoted on one side to an axis in the air intake pipe across to the air flow direction. The air intake section opposite the pivot plate axis is so shaped that the pivot plate moves in an approximate linear function to the incoming air, that is on slow running nearly closed and fast running fully open. The plates movement is transferred to a fuel metering plunger which also serves as a return for the plate. The plate pivot axle has a fixed lever which carries a peg to which is attached one end of a pull spring, the opposite spring end being fixed to a point on the intake pipe. When the plate moves to the fast running position, the tension spring works against the fuel pressure return force and in the slow running position in the opposite direction so that an increase in the pressure difference takes place during slow running and a decrease on full load.

Title: Cct. breaker with sulphur hexafluoride quenching - has commutator in arc burner space for arc current shifting
Inventor: SCHMITZ WOLFGANG DIPL ING
IPC: H01H33/90
Filed: 1974-01-24
Abstract: The quenching contact arrangement consists of stationary and moving contacts in a quenching chamber, at least one having a nozzle-shaped inner channel for introducing a pressurised quenching gas, such as sulphur hexafluoride, as in 2349263. The arrangement generates two light arcs in the arc burning chamber, in which is provided a commutating device which switches over the current flowing in closed condition over the normal circuit breaker contacts onto additional contacts during switching off, in order to generate the second light arc. Thus the currentless contacts in closed condition take over during switching off the current, thus pulling between them the second light arc.

Title: Magnetically guided magnetic-track-bound hover vehicle - with electromagnets movable to setting where interval from rail is increased
Inventor: RIEGLER MANFRED DIPL ING
IPC: H02K41/025
Filed: 1974-05-24
Abstract: The track-bound vehicle is laterally guided and/or carried freely hovering, by electromagnets opposite magnetically conductive rails. The electromagnets can be moved from a normal ideal position relative to the rail involved, into a position where the distance between them and the rail is greater than a prescribed ideal distance. A vehicle with linear motor drive may have its motor component movable out of an ideal setting relative to the stationary motor component, into a position where the interval between the motor components is greater than the normal ideal distance. The electromagnets may be movable against the action of spring elements, likewise the vehicle's motor component; or both may be movable against the action of a clamp device which exercises a defined holding force.

Patent DE-2429136-A1 (DE)
Title: Position or angle dependent capacitor electrode - designed for automatically controlled machine tools
IPC: G05D3/14
Filed: 1974-06-18
Abstract: The width of the capacitor electrode at measurement point, measured in a plane perpendicular to the tangent to the measured variable, is a function of the variable itself. Two surfaces, interlaced with each other, generate a potential field, function of position or angle. In practice a capacitor is connected directly or at an angle with a standard measurement capacitor. Alternatively, two direct or angle dependent capacitors are placed within a capacitative voltage dividing circuit. A capacitor surfacing is provided whose width, vertical to the measured value, is itself an unambiguous function of the measured value. This ensures the highest possible dependence of the capacitance upon the measured values.
Patent DE-2431327-A1 (DE)
Title: Conveying system for letter processing machine - conveyor points are activated according to monitored distances between successive letters
Inventor: GOLDKUHLE GERHARD
IPC: B65H43/00
Filed: 1974-06-29
Abstract: The system has two sets of points in a conveyor path, each set being controlled by the output of a store, which receives a control command, when a letter moves onto the conveyor path. A gap testing unit (12, 21, 23) issues an output signal, when the gap (C) between two subsequent letters is smaller than a predetermined minimum distance (B). Switch units (27), alter the store (I, II) condition, corresponding to the control commands for these letters. This causes the letters to be moved to a common outlet (8) for letters at insufficient distances. The store has a connected comparator (28), the output signal of which depends upon the corresponding control commands for both letters. The outlets of testing unit and the comparator are connected to the inputs of a linking circuit (26). The circuit allows the signal from the testing unit to reach the switch units, only when the control commands do not correspond.

IPC: D02G1/02
Filed: 1974-09-27
Abstract: A false-twist installation for crimping thermoplastic yarns, with a first and second yarn feeding arrangement linked by a drive transmission permitting their speeds to be regulated relatively, the one to the other, and between them devices for impairing false twist and heating, the twisted yarns to plasticising temp. as well as a cooling arrangement between te false-twister and the heater, for chilling the softened filaments, has the cooling device formed by a hollow body over which the yarn runs, acting as a vaporiser for a refrigerant, and connected pressure tight to the refrigerant condenser by permanently open lines. In the one connecting line a device with a capillary structure such as a wick, automatically transfers the condensed refrigerant from the condenser to the surface of the vapouriser. The dwell time in the cooling arrangement is reduced so that the necessary height of the installation can be lowered. The cooler requires very little maintenance, has no mechanical wearing parts and very low running costs.

Abstract: Bands for use in the reinforcement of seams, esp. armhole seams in garments from knitted fabrics, are warp knitted from textured single or double yarns, the weft threads being laid in alternately in "S" and "Z" twisted yarns. The seam band has a running length between 900 and 5000 m/kg and an elasticity between 30 and 100%. The number of weft threads in the band is even. The threads forming the stitches are also alternately of "S" and "Z" twist and are one more in number than the weft threads. The band has an open tricot construction with the weft threads of guide bar one moved in sinus form over only one neighbouring needle, and the stitch forming threads of guide bar two are displaced laterally. The band is stable in width under tension. It is of great length and can be produced at high speed together with a number of others of the same or different widths simultaneously on one machine.
