Patent DE-3331404-A1 (DE)
Title: Free piston engine for the generation of torque
Inventor: RAEHMER HANS
IPC: F02B71/00
Filed: 1983-08-31
Abstract: For converting the piston thrust of free piston engines into a torque a free wheel unit is used in which a rack cage is fixed to the working pistons. The freely oscillating rack cage runs transversely about a fixed output shaft on which free wheels having gear rims and where necessary bearings are fixed. Over these gear rims the racks, arranged offset, perform a straight line reciprocating movement. In each case at least one rack functions on each side of the output shaft on one of at least two free wheel gear rims, the free wheels working in the same direction. Due to the offset arrangement of the racks the output shaft is made to rotate in the same direction of rotation both on the advance thrust and on the return thrust. If there is no pressure acting on one of the pressure pistons or piston sides, the shaft turns freely in the direction of rotation. Pressure actuation of the cylinder can be produced both by pressure media and by combustion engine principles.

Patent DE-3404307-A1 (DE)
Title: Drawing apparatus
Inventor: BICKEL FRIEDRICH
IPC: B21D24/08
Filed: 1984-02-08
Abstract: The drawing apparatus consists of a drawing punch, a blank-holder top part and a blank-holder bottom part with displaceable pressure pins, of a pressure pad arranged displaceably in the blank-holder bottom part and of a punch plate which is situated underneath the blank-holder bottom part and can be moved up and down. The punch plate has a piston resting on an air cushion and arranged in a compressed-air cylinder and is in operative connection with a pressure pad, which serves to support the workpiece during the drawing operation and for ejecting the finished workpiece, and with pressure pins for controlling the pressure of the air cushion. The air-pressure cushion in the compressed-air cylinder forms a kind of spring and is maintained over a long period, making it unnecessary to supply and withdraw any compressed air as is the case where the piston is controlled by pressurisation on both sides by compressed air. This saves energy and costs.
Patent DE-3404918-A1 (DE)
Title: Air-operated gear motor
Inventor: LUBOS WALTER
IPC: F01C21/00
Filed: 1984-02-11
Abstract: The air-operated gear motor 1 of the invention has an internal gearwheel 19 with internal toothing 20, which is supported radially and axially, via a deep-groove ball-bearing 24, partially in the motor casing 2 and partially in the casing cover 4. The deep-groove ball-bearing 24 is aligned centrally with respect to the internal toothing 20. By the use of a deep-groove ball-bearing 24 with shoulders on both sides of the balls and by the central alignment of the internal toothing 20 and the deep-groove ball-bearing 24, it is possible to dispense with any further support for the output stub shaft 22, making the motor casing 2 shorter. In addition, the manufacturing outlay is reduced since, in comparison with two-print support, the work involved in the accurate machining of the bearing locations of the second bearing and the associated outlay on materials are eliminated. <IMAGE>

Title: Mass spectrometer, especially for the analysis of insulators
Inventor: SHIOKAWA YOSHIRO
IPC: G01N27/62
Filed: 1984-12-27
Abstract: In a mass spectrometer having an ion gun 10 for directing an ion beam onto the surface of a sample 12, so that said sample 12 emits secondary ions, having a detector 18 for the secondary ions and directing means 20a, 25a, for directing the secondary ions onto the detector, a specific energy bandwidth can be defined on the basis of the energy distribution of the secondary ions with respect to the maximum of the energy distribution. The energy region of the mass spectrometer which can be analysed can be expanded, according to the invention, to at least double the specific energy bandwidth by means of expansion devices which are coupled to the directing means. Using the expansion devices, the pass bandwidth of an energy filter belonging to the directing means can be enlarged in that the resolution and the mean energy of the pass band are increased. The expansion means can also increase the maximum energy of a quadrupole mass filter which can be analysed, especially by modifying the length of the electrode elements of the mass filter and/or by modifying the frequency of an alternating voltage which is supplied to these electrode elements. <IMAGE>

Title: Cleaning appliance movable along textile machines
Inventor: STEPPE KURT
IPC: D01H11/00
Filed: 1985-02-05
Abstract: In a cleaning appliance movable along textile machines, the hose, the path of movement of which overlaps with the path of movement of a service trolley, has a rotary joint, to which a hose part with an S-shaped bend is connected. When the cleaning appliance is operating normally, the hose part runs underneath the S-shaped bend near the textile machine and ensures, via the nozzles located there, a thorough cleaning of the side of the textile machine. When the cleaning appliance approaches the service trolley, the rotary joint is actuated by means of proximity sensors, with the result that the hose part running underneath the S-shaped bend is pivoted away from the textile machine and therefore out of the path of movement of the service trolley. The cleaning appliance can thereby pass the service trolley.

Abstract: The shaft 1 of the rotor carries a pinion wheel 2, which drives satellite gears 3, which rotate on axes 9 which are fixed to a plate 10, which are supported freely rotatable on the said shaft by means of a bushing 11. This bushing forms the inner running surface of a drive system acting in one direction, which has rollers 12 and an outer cage 13, which is provided with ramps 13a. The cage is fixed to the inner end of a coil spring 15, the other end of which is fixed to a fixed rod 16. As soon as the shaft 1 is made to rotate, the drive system acting in one direction locks in order to initially tension the spring and then immediately set the epicycloidal reduction gear into operation so that its satellite carrier plate is arrested. As soon as the internal combustion engine accelerates after each explosion in the starting phase, the spring is retensioned in order to keep the teeth of the pinion wheel 6 in contact with those of the large gear ring 18 of the internal combustion engine. <IMAGE>
