Title: Device for ionising a polarised atomic beam
IPC: H01J27/18
Filed: 1988-08-30
Abstract: A polarised atomic beam 1 is ionised in a device (Fig.) in an alternating field at an electron-cyclotron-resonance frequency. In this case, the nuclei or ions of the beam remain polarised. An electric field originates from extraction electrodes 8 and focuses and further accelerates the ion beam 3a. The electrodes 8 are hollow discs having a specific minimum width of the hole diameter, which has proved essential for maintaining the polarisation of the ions. The electrons remain trapped in a magnetic mirror field. <IMAGE>

Title: Hydraulic brake system with slip control
Inventor: VOLZ PETER DR
IPC: B60T8/32
Filed: 1988-11-03
Abstract: A brake system is demonstrated, in which a return unit is provided, by means of which a return force can be exerted on the pedal. Since the pedal simultaneously actuates a control valve 9, which determines the booster force, a reduction of the booster force also occurs in the event of a return. The wall 40, which absorbs the return forces, can be advantageously arranged in the booster housing 5 between the master cylinder 1 and the booster wall 6. Since it only performs small relative travels compared to the booster wall 6, the overall length of the booster housing 5 is not significantly increased. Further alternative embodiments are presented in the application. <IMAGE>

Title: Stress-proof (voltage-proof) connecting joint
IPC: H01R13/658
Filed: 1989-01-14
Abstract: Previous stress-proof connecting joints always required the housing of an electrical apparatus to be opened in order to lay cables connected in the interior of the housing or to fit new cables. In order to enable a lighter (easier) stress-proof connection, the connecting joint is designed in the form of a plug and/or socket. A connection outer sleeve (3), which surrounds a cable connection head (15) forming a connecting part is in this case electrically separated from and fixed with respect to a cable insertion sleeve arrangement (1, 9, 11) via an insulator (7) arranged in between. The connecting joint is particularly suitable for connection to a mating element which is constructed on a housing wall of an electrical apparatus. <IMAGE>

Inventor: STEIN IVAN
IPC: H05B44/00
Filed: 1989-03-04
Abstract: In a known arrangement for producing current pulses for semiconductor diodes emitting radiation, a piezo element is mechanically loaded and the voltage pulse thus generated is injected into the circuit of the semiconductor diode by means of a transformer. The novel arrangement is intended to make it possible to generate the current pulses without using piezo elements in addition to not using a supply voltage source. The mechanical energy pulses are transformed in an inductive manner into voltage pulses. <IMAGE>
Patent DE-3913866-A1 (DE)
Inventor: ARNDT FRIEDRICH-KARL DR ING
IPC: B25D9/14
Filed: 1989-04-27
Abstract: The invention relates to a hydraulic striking mechanism including a cylinder, a percussion piston guided therein and a piston return device which is supported on the percussion piston and is displaceable independently thereof and can be connected on its side facing the percussion piston tip alternatingly to a pressure source or a pressure-free return conduit. The piston return device is configured as an annular piston which is freely displaceable along the percussion piston and the cylinder and forms therewith a piston chamber. The percussion piston has an abutment face at its end remote from the percussion piston tip which cooperates with the annular piston for moving percussion piston in the return stoke direction. The percussion piston, together with the cylinder, defines an oil chamber which axially follows the piston chamber in a spaced relationship. The percussion piston is provided with a cylindrical shoulder within the oil chamber which determines its end position during the return stroke. The piston chamber and the oil chamber are connected with a control unit by means of which, when the percussion piston shoulder approaches the rear face of the oil chamber, the oil chamber can be connected to the return conduit and by way of which, when the annular piston approaches an annular face on the cylinder, the piston chamber can be connected with the pressure source.

Title: Infinitely adjustable gearwheel drive - has constant drive speed but variable output speed even into reverse
Inventor: RUEHLEMANN JOACHIM
IPC: F16H29/00
Filed: 1989-05-18
Abstract: The infinitely variable gearwheel has two optional output directions (16). The elements (6,7,8,9) which are mounted on a rotor (13) change the speed.

The oscillating movement already exists or is produced in addition to the rotary movement of the drive shaft. Relative movements (37) such as the inner relative movements of the components (35) of a cardan joint, individual components or structural gps. of a gearbox, can be converted into a continuous rotary movement of the driven output shaft (2). USE/ADVANTAGE - The gearwheel infinitely variable gearbox for a vehicle is smaller and lighter than friction wheel or draw pulley gears but has a higher output.
