Patent DE-3802418-A1 (DE)
Inventor: KARLE ANTON DIPL ING
IPC: F02D41/40
Filed: 1988-01-28
Abstract: In a process for metered injection of fuel in a distributor-type fuel injection pump, the metered quantity of fuel is governed by the duration of closure of a solenoid valve (29) arranged in a connecting line between the working and discharge chambers of the pump. The duration of closure of the solenoid valve (29) is determined from the ratio of a theoretical angle of rotation of the pump piston (14) for the injection stroke, calculated in function of engine operating parameters, and a constant angle of rotation covered by a measurement window evaluated over time, multiplied by the flow time measured in the measurement window. To determine changes in engine speed between the time of evaluation of the measurement window and the injection of fuel, a metering window covering an identical angle is evaluated over time during the injection of fuel and a correction factor is calculated from the ratio of the metering and measurement window times and used to correct the measured duration of closure of the solenoid valve (29) during the next piston stroke.

Patent DE-3811846-A1 (DE)
Inventor: KRONBERGER MAXIMILIAN DIPL ING
IPC: F02M57/02
Filed: 1988-04-08
Abstract: The invention relates to an injector-pump unit for diesel engines, in which an injection-pump element having a pump plunger (1) driven by a camshaft and having an element bushing is combined with an injection nozzle to form a unit which is to be assigned to in each case one engine cylinder. The pump plunger (1) is surrounded by an axially displaceable control sleeve (11) which controls the beginning of injection as a function of its axial position. A regulating member (15) is guided on the pump-element body (10) in such a way as to be rotatable relative to the control sleeve (11) as a function of an operating parameter of the engine. The control sleeve (11) or the regulating member (15) has a track (25, 46, 50, 52) extending in a circle in plan view, which at least in part encloses an angle of inclination with a plane normal to the axis of the pump plunger (1). Interacting with this track is a guide element (23, 47, 49, 53), which is rigidly connected to the respective other part (namely the regulating member (15) or the control sleeve (11)). Due to the interaction of this guide element with the track, the control sleeve (11) is raised or lowered upon relative rotation and hence the beginning of injection controlled. The track (25, 46, 50, 52) can also have angles of inclination of varying size and/or direction in successive sections.

Title: Carrier strip with connecting lugs for electrical components, and a method for fitting the carrier strip
Inventor: RABITSCH WOLFGANG
IPC: H01G4/228
Filed: 1988-05-10
Abstract: A carrier strip with connecting lugs for electrical components, and a method for fitting the carrier strip. The metallic carrier strip has electrical connecting lugs for electrical capacitors or other electrical or electronic components which have in each case one metal coating on two mutually opposite ends, with which metal coating an electrical connecting lug is in contact. The carrier strip consists of two parallel edge strips, transverse strips which connect them to one another at a distance from one another like conductors, and connecting lugs which are arranged spaced apart between the the transverse strips, in each case originate from one of the edge strips and are aligned with one another. According to the invention, a longitudinal slot is constructed in one of the edge strips in the region of its inner edge between two adjacent transverse strips, which longitudinal slot extends on both sides beyond the foot of the connecting lug, which originates from this edge strip, between these two transverse strips. In order to fit the carrier strip with the components, the end sections of the connecting lugs are initially bent over, after which the respective component is inserted between the connecting lugs and the bent-over end sections are pressed against the component. In this case, the respective longitudinal slot is expanded transversely so that existing length tolerances of the components are compensated for.

Title: Read amplifier
Inventor: ITO JUNKO
IPC: G11C7/00
Filed: 1988-08-03
Abstract: The intention is to make available a read amplifier which is of simple construction, which is suitable for high speed operation and in which the capacitance of the bit line has no effect on the read operation. This object is achieved by a read amplifier which has a pair of bit lines (B1, B2), which are connected to a blind cell and a large number of memory cells, a pair of n-channel MOS transistors (Q1, Q2), which are connected between the pair of bit lines and an input/output line and operate in response to the potential of the respective other bit line, and a pair of p-channel MOS transistors (Q5, Q6), which are connected between the pair of n-channel MOS transistors (Q1, Q2) and the bit lines (B1, B2) and respond to the earth potential. When the voltage difference of the pair of bit lines is amplified, the p-channel MOS transistor which is connected to the bit line which is held at lower potential opens, and the connection between the bit line and the n-channel MOS transistor is broken. Such read amplifiers are particularly used in dynamic RAMs. <IMAGE>

Title: Device for input of 3-dimensional co-ordinates and movements for computers
Inventor: SCHAEFER HARTMUT
IPC: G06F3/0346
Filed: 1988-11-15
Abstract: The invention concerns an input device with which three-dimensional co-ordinates and movements can be input to computers. Externally, it resembles a "mouse", but differs from it in that it can not only be moved in the plane, but also raised and moved in space. Absolute spatial co-ordinates are thus transmitted to the host computer. The way the spatial co-ordinates are determined is that the distances of the input device from at least three fixed reference points is determined using a high-precision ultra-sound measuring system, and the spatial co-ordinates are calculated from them. The way the ultra-sound measuring system works is that, from a specified calibration point of known co-ordinates, the full phase shifts of the continuously transmitting input part are counted in relation to the received signals, and the phase shift is measured.

Title: Apparatus for the simultaneous texturing of a multiplicity of multifilament threads
Inventor: BAUER KARL DR ING
IPC: D02G1/16
Filed: 1988-11-17
Abstract: In textured yarns produced on conventional machines for individual thread treatment, an identical treatment on all the machine stations cannot be achieved. At least small differences are to be taken into account during drafting and during heat treatment or texturing treatment. Dye affinity, shrinkage behaviour and force/stretch behaviour react sensitively to such differences. The new apparatus is to allow uniform treatment even in the case of a large number of threads. The new apparatus consists of a plurality of parts with a respective plurality of texturing devices, each for one to three threads. The thread set is subdivided into groups, the number of which corresponds to the number of parts. The parts are arranged at a lateral distance from one another. The parts can be offset relative to one another in the thread running direction or in height. The texturing devices can be false-twist devices or air-texturing nozzles. The threads are wound up jointly. High thread uniformity is achieved as a result of the joint treatment and winding.

Inventor: LEMMER OLIVER DIPL ING
IPC: H01J37/32
Filed: 1989-06-24
Abstract: The invention relates to a device for coating substrates by cathodic sputtering in which the anode is specially designed. The effective anode area is limited by a shutter which is metallically conductive and preferably connected to the inner wall of the chamber and thus is at its potential. The effective anode area is matched to the cathode power so that there is an optimally high ion concentration within the entire chamber. This results in good adhesion of a coating even in those regions which are coated only by means of cathode or substrate movement at a later time.
