Patent DE-3900346-A1 (DE)
Inventor: WEIPPERT WILLI DIPL ING
IPC: F02D1/18
Filed: 1989-01-07
Abstract: A fuel injection pump for internal combustion engines, in which the pressure of the control fluid of a hydraulically operating injection timer (22-31) is controllable by way of two outflow throttles (43, 44) to achieve a relative advancement of injection, in the event of a cold start, and a relative, load-dependent retardation of injection. The two outflow throttles (43) and (44) are disposed in the governor sleeve (35) of a governor (12). A control valve (47) through which, in the closed state, the two outflow throttles (43) and (44) can be rendered inoperative, is disposed downstream of said outflow throttles (43, 44), the first (43) of which serves to retard injection on a load-dependent basis. Because the throttles, in particular the second outflow throttle (44), are rendered inoperative by closure of the valve (47) in the cold-start phase, the pressure of the control fluid increases and causes a corresponding adjustment to provide an early commencement of delivery. Later, as the engine warms up, the valve (47) opens to cancel this effect. <IMAGE>

Title: Method for determining and correcting the combustion space volume of an internal combustion engine
Inventor: LEHNER FRANZ
IPC: G01F17/00
Filed: 1989-03-22
Abstract: In order to determine the volume of a combustion space in the cylinder head of a reciprocating piston internal combustion engine, the surface of the combustion space is subdivided into area segments which are established, for their part, in a coordinate system by means of at least one marking point. The coordinates of this marking point are determined and compared with the respective desired coordinates. The corrective measures necessary for achieving the desired volume are derived herefrom. For this purpose, in particular, the valve-seat rings are reworked in various ways.

Patent DE-3938234-A1 (DE)
Inventor: HODES ERICH DIPL CHEM DR
IPC: B22D19/08
Filed: 1989-11-17
Abstract: An alloy, in the form of a metallurgical two-component or multi-component system with a miscibility gap (monotectic), is continuously cast and immediately subjected in a continuous run to cooling with a sufficiently high solidification rate to restrict growth of particles of the immiscible metallurgical components such that the particle dimensions are not greater than 1  mu m, preferably in the range of 0.01 to 1  mu m. A foil may be cast for this purpose from the alloy and chilled at a high cooling rate. This foil may then be joined by a method employing laser beams, to a substrate forming the backing for the bearing (Fig. 7, not shown). The alloy may alternatively be cast directly onto a backing substrate in one or more stages (Figs. 3-6, not shown). The substrate may be a composite strip formed by a steel backing and an intermediate layer of a bearing metal having good antiseizure properties. The following metallurgical two-component or multi-component systems with miscibility gap may be used for casting the overlay: AlPb, AlSn, AlBi, AlSb, CrPb, CrSn, MnPb, FePb, CoPb, NiPb, CuPb, and PbZn. <IMAGE>
Patent DE-4001650-A1 (DE)
Title: Circular knitting machine - has sensor and circuit to identify imperfections in the fabric
IPC: D04B35/20
Filed: 1990-01-20
Abstract: The process to control imperfections in the fabric produced on a circular knitting machine is based on the sensitivity of devices using reflection at a suitable angle. Impulses at a certain frequency form reflections from perfect fabric which creates no reaction. Imperfections in the fabric cause changes in the frequency which are sensed by a gate in the circuit, transmitted to a monostable and accumulated, but constant repetition causes the machine to stop. The appts. is also claimed. The sensor box (6) is placed close to the cloth (2) and may be adjusted by arm (7) to align to the loops of the fabric. The cloth is constantly at the correct angle by means of an oval ring (11) as part of the take-down mechanism (3). A light (12) and screen (13) provide a constant source of light to the sensor as a reference to eliminate spurious reflections. The sensor contains a row of infra-red diode sensors and alternatively emitters. This light is reflected from the fabric along channels in a screen. The emitters are supplied from a standard frequency source, then the sensors actuate a frequency diffentiator where interference patterns are rejected. The signal is amplified, and when the fabric is perfect producing a normal signal, this is inverted, with output zero. Imperfections cause a frequency disturbance in the circuit. The circuit is pre-set and controlled in such a manner that a knot in the yarn will be ignored, but a knot that bends a needle will create a repetitive signal from that point, which stops the machine. USE - To reduce number of imperfections in the knitted material with inexpensive equipment.

Title: Circular knitting machine - utilises pattern control to employ two cam tracks with three-way technique
Inventor: COTTENCEAU REMI
IPC: D06F75/16
Filed: 1990-03-08
Abstract: Circular knitting machine utilises the three way technique on a bed of latch needles. One butt engages in the top cam track while the two lower butts engage by selection in one of the two lower tracks. - Pref. there are three cam sections to channel the butts, and lift the latch needle into miss, truck or knit height. A top dial with cam is employed to actuate the sinker platines. The swivel butt section in the lower part of the needle, is controlled by a pattern selector, using electro-magnetic, electronic, or mechanical means to press a control rod up or down, onto the end of the swivel. This means that only one butt at a time, may be engaged in the tracks of the cam sections. When the butt is engaged, the cam track is restricted to the level, which is tuck height. - By means of the controller and the design of the track either butt may be depressed into a miss track, which coincides with the diversion on the point of the cam between track, located in the cam section, and which guides the butt. On account of the controlled selection, the butt passes smoothly into the miss or knit channel. The swivel butt principle may also be extended to other forms of knitting actuators, such as sinkers, platines, plush points, etc.. Rib needles and sliders may be used on the machine.
