Title: Screw pump comprising a screw piston performing a circular rotation, and a moving double-walled rubber cylinder
Inventor: HORVATH IMRE
IPC: F04C2/107
Filed: 1988-11-03
Abstract: The screw piston is the extension of the shaft of the driving electric motor, and the rubber cylinder is fashioned with a double wall and is able to yield laterally in accordance with the eccentricity of the screw piston. In the space between the two walls of the rubber cylinder these always obtains a pressure which corresponds to the current delivery head of the pump and which correspondingly forces the cylinder against the piston. The motor and the pump chamber are sealed in a water-tight manner with respect to one another via a seal having a slide ring. The pump operates according to the principle of spatial displacement, its delivery rate is virtually proportional to the rotational speed.
Patent DE-3841523-A1 (DE)
Title: Method of cutting off the top end of foundation elements of cast-in-situ concrete, and apparatus for carrying out the method
Inventor: SCHMIDT UWE
IPC: E02D9/00
Filed: 1988-12-09
Abstract: In the case of foundation piles made of cast-in-situ concrete, the earth first of all had to be excavated to the intended level after the piles were constructed. The ends then projecting above the level had to be laboriously cut off with compressed-air tools, the then accumulating concrete rubble having to be removed separately. According to the invention, immediately after the concrete is placed, the cement portion of the concrete, which has not yet set, is flushed by means of water out of the borehole down to a predetermined depth. In this procedure, only loose gravel remains in the upper area of the borehole. The gravel can be carried away in one operation during the subsequent excavation of the earth. All that is necessary is for any reinforcement to be then burned off. <IMAGE>

Title: Electric staple gun with auto-resetting, energy-saving and safety function
Inventor: TAN LAI WEN
IPC: B25C5/15
Filed: 1989-01-05
Abstract: The invention relates to an electric staple gun with auto-resetting, energy-saving and safety function and relates in particular to a staple gun of this type which uses a projection (33) of a lever rod in order to switch on a second microswitch (7), in order to re-actuate a motor (9), in order to move the lever rod (3) out of its dead-centre position when it stops in such a dead-centre position. Furthermore, the electrodes of the motor (9) are interconnected in order to generate a reversed electromotive force for producing a braking action of the motor (9) within a short time, in order to enable a high speed of the motor (9) before the next operation. In addition, a safety bolt (60) is provided in order to avoid unintentional actuation of the staple gun. <IMAGE>
Patent DE-3902629-A1 (DE)
Title: Position-change switch
Inventor: MATHEY CHRISTOPH DIPL ING
IPC: H01H35/02
Filed: 1989-01-30
Abstract: A switch which responds to position changes and has a ball as the contact-making device can be made less sensitive if the ball has to overcome a threshold, preferably at least twice, before the event to be recorded produces the desired switching process. In the case of the switch, the baseplate is domed upwards or downwards towards the centre and, in addition, guide grooves in the baseplate preferably ensure that the balls must always roll over the highest or lowest point of the dome if they wish to reach the other contact pin. A similar effect for reducing the sensitivity is achieved if the evaluation circuit is adjusted such that the balls must be present on at least two different grooves before the desired switching process can be carried out.
