Title: Weaving loom - has weft insertion by acceleration provided by rapid release of airjet projectile equipment
Inventor: GROSMANN HANS
IPC: D03D49/42
Filed: 1992-06-06
Abstract: Acceleration equipment for a weft injector on a weaving loom has a tube, with a projectile for the yarn. Pressure is developed through a valve into a cylinder attached to the tube, and the projectile is released by a catch. The projectile is loaded sideways into the tube, and sealed, and then the catch is rapidly released, by a timing mechanism. The accelerator has a sloping catch to retain the projectile in the tube. This is directly connected to the air chamber with a valve to open and close the air pressure supply inlet, coupled to the timing mechanism. The rear of the projectile has an air inlet and ball grips for the weft. There are angular jets in the projectile walls. Guides move the accelerated weft into the return channel. ADVANTAGE - The valve allows an increased amount of pressure to build up before the quick release catch permits the projectile to move. This allows the accelerator to operate quicker.

Title: Timing control for four-stroke IC engine with odd number of cylinders - has control signals generated from uniformly spaced signals generator and non-uniformly spaced signals generator
Inventor: FUKUI WATARU
IPC: F02P7/067
Filed: 1993-06-25
Abstract: The engine has one signal generator (1A) driven by a crankshaft linked rotating shutter with uniform spacing tags. A second signal is generated by a shaft rotating at half the crankshaft speed and fitted with a non-uniform tag shutter to generate the cylinder identity signals. The signals are proportional to the number of cylinders multiplied by a natural number. A processor computes the actual timing points for the separate cylinders . The system provides accurate, electronically derived timing signals by generating control signals at frequencies derived by dividing the crankshaft signals by the number of cylinders multiplied by the natural number. A similar computation derives the cylinder identity. ADVANTAGE - Improved accuracy timing control, minimum of sensors required.

Patent DE-4328906-A1 (DE)
Title: Hydrostatic actuator
Inventor: BACKE W PROF DR ING
IPC: F15B21/0423
Filed: 1993-08-27
Abstract: A hydrostatic actuator possesses as hydraulic final control element, for example, a double-acting piston-cylinder unit. The chambers of the hydraulic final control element are fed by a reversible variable displacement pump, the pump being driven by a constant-speed motor. If the variable displacement pump is in the neutral position, i.e. the delivery flow is zero, the heat produced in the pump is unable to flow off with the hydraulic fluid. To avoid overheating when the actuator is fixed in a given position, a further, fixed displacement pump is connected in parallel with the variable displacement pump and to the chambers of the hydraulic final control element. The fixed displacement pump delivers a given volumetric flow continuously from one of the chambers into the other chamber. Consequently, the variable displacement pump is forced to compensate for the volumetric flow delivered by the fixed displacement pump in order to maintain a rest position of the final control element. As a result, heat is carried away.
Patent DE-4329960-A1 (DE)
Title: Permanent magnet arrangement for producing a defined variable magnetic field
Inventor: GROENEFELD MARTIN DIPL PHYS DR
IPC: H01F7/02
Filed: 1993-09-04
Abstract: The permanent magnets (1) of the permanent magnet arrangement are in each case mounted individually such that they can rotate about their centre axis (5) parallel to the common system centre axis (2). The rotation of all permanent magnets (1) is synchronised such that adjacent permanent magnets rotate in the opposite direction with respect to one another in order to change the intensity of the multipole field or in the same direction as one another in order to change the direction of the multipole field in the interior (4). The centre axes (5) of the permanent magnets (1) are parallel to the system centre axis (2). In this way, the fields of permanent magnets of the same shape and size can easily be compensated for in the case of such a permanent magnet arrangement, with the arrangement having a simple construction. The intensity of the field in the interior or the multipole moment can vary continuously by mutual rotation of the magnets. All the rotations can easily be coupled by means of toothed pinion wheels which engage in one another and are fitted on the magnet shafts, underneath the permanent magnets. Rotation of all magnets in the same direction can also be used to change the field direction. <IMAGE>
