Title: Ball transporter for charging tennis ball serving machines
Inventor: KIESGEN ERNST-JOERG DIPL ING
IPC: A63B69/40
Filed: 1988-05-04
Abstract: A technical apparatus serves to transport tennis balls reliably from a collection of tennis balls upwards to any desired height. Arranged below a collection point for tennis balls is a ball regulator which separates the tennis balls (as implemented in current tennis ball serving machines). These tennis balls (7) now roll, as shown in Fig. 1 of the drawing, individually and in sequence on a descending ramp (9) to a roll-off surface (10). The distance between the rotating belt (12), which is guided by the belt pulleys (R15) and (R16), and the roll-off surface (10) is less than the diameter of tennis balls (7). As a result, the tennis balls are gripped at the belt pulley (R16) and are lightly compressed, and then automatically roll upwards between the belt pulley (R16), the belt (12), the belt pulley (R15) and the roll-off surface (10). Following this automatic guidance, the tennis balls (7) roll over an internal descending ramp (13) onto an external descending ramp (14) and drop from there into a tennis ball serving machine. This ball transporter can be used in so-called tennis training or serving channels. <IMAGE>

Abstract: The automatic stacking device comprises a stacking housing which represents an empty skeleton structure. Four approximately U-shaped supports together form in each case one pillar which has sets of toothing or the like which are provided for a climbing drive, and also force and switching lines. The transverse connections are at the same time groove-wheel rails which are equipped with girders and power and switching-current lines and have, in the direction of the U-openings, cutouts for the passage of pinion spindles and the like. The floors, which are absent everywhere, are replaced by displaceable floor plates which can move forwards and backwards and, at right angles thereto, to the left or to the right in one plane, and move upwards or downwards in every shaft of the stacking house. The movement excitation takes place via a switching-current address of the respective displaceable floor plate by means of a counting or ordering device via a progress calculator. The counting and ordering device first of all determines the location of the displaceable floor plate by identification-number input for the displaceable floor plate and input of the destination in the stacking housing. The progress calculator calculates, on the basis of the called-up location and the activities of the other displaceable floor plates, the next movement step towards the desired target and brings about the switching pulses. Using frictionally engaged movement drives, exact holding points are possible, which ... for the change in direction... Original abstract incomplete.

Title: Protective circuit for a switched-mode power supply circuit
Inventor: OH YONG HEE
IPC: H02H7/12
Filed: 1988-11-30
Abstract: The invention relates to a protective circuit for a switched-mode power supply circuit (or link power supply circuit) in which, whenever a constant voltage is not output, the through-connection/blocking operation of a switching transistor is ended if an overvoltage appears at the output of the power supply circuit. This protective circuit essentially contains a switching transistor, a diode, a phototransistor, a thyristor, a capacitor etc. connected to a photodiode, a Zener diode, a thyristor etc. as well as other conventional components. Whenever, for example because of a short-circuit of the load circuit, an overvoltage is emitted, or a current surge flows, the protective circuit is capable of protecting the power supply circuit while, at the same time, unnecesssary waste of the current supplied via the current-input terminal can be avoided. <IMAGE>

Title: Solenoid valve
Inventor: BARTHOLOMAEUS REINER DIPL ING
IPC: H01F7/16
Filed: 1989-03-22
Abstract: The invention relates to a solenoid valve, the armature of which is arranged on a sleeve which is mounted on both sides of the solenoid armature space in order to largely avoid the ingress of foreign particles into the armature space. The operability of the solenoid valve is improved by leakage fluid being drawn off to the tank in the area of the pressure-side bearing point, and in addition the valve connections are arranged in such a way that no pressure gradient bears on the solenoid armature space. The ingress and depositing of foreign particles in the armature space is thus effectively avoided.

Title: Discharge fitting for flushing cisterns
Inventor: JOEHRI HAIMO
IPC: E03D9/14
Filed: 1989-06-09
Abstract: Upstream of an outlet opening (14), the discharge fitting exhibits a valve seat (4) which interacts with the valve disc (3) of a valve tube (1). For opening the valve, the valve disc is to be drawn upwards and, for interrupting the flushing, can be moved downwards onto the valve seat (4). Fitted on the underside of the valve disc (3) is a body (6) with a cylindrical surface (15). Just before the closure of the valve, a bottom edge (18) of the body (6) forms, with the mouth edge (7) of the outlet opening (14), an annular gap (19) in which the flow resistance is considerably greater than upstream thereof. Just before the closure, the pressure drop on the underside (F2) of the valve disc (3) is thus reduced and the impact of the valve disc (3) on the valve seat (4) is damped. <IMAGE>
