Patent DE-4242174-A1 (DE)
Inventor: DAUB WOLFGANG
IPC: H05B41/36
Filed: 1992-12-15
Abstract: In a ballast for starting and operating high-pressure gas-discharge lamps, having at least one current- and/or power-controlled voltage transformer which is connected to a high-pressure gas-discharge lamp via a start device and is connected to a current/power controller which feeds a current/power desired value to the voltage transformer, having a comparator which generates a switching signal as a function of an input signal, and having a capacitor which is charged with a first time constant as a function of the switching signal generated or discharged with a second time constant and whose voltage determines the level and the duration of an additional power which is fed to the high-pressure gas-discharge lamp after the start, for the purpose of ensuring that both in the starting phase and in the stationary operation of the high-pressure gas-discharge lamp the current or the power which is fed to the lamp is controlled as exactly as possible in a lamp-dependent manner, an input signal is present at the input of the current/power controller, which corresponds to the lamp voltage. In this arrangement, the timing elements which determine the time constants are connected to the other components of the current/power controller via low-leakage rectifiers, and a high-resistance leakage current compensation circuit compensates for the leakage current of the capacitor and stabilises its voltage in stationary operation. <IMAGE>

Title: Multiple weighing device for bulk goods, having a double funnel-flap mechanism
IPC: G01G13/16
Filed: 1993-03-12
Abstract: A multiple weighing device (10) having a double funnel-flap mechanism comprises a feed device (12) which delivers the goods to be weighed and to be packaged to a weighing station (14). The goods conveyed into the weighing station (14) are weighed and the portion thereof which has a desired weight is then transported into a packaging station (16), where it is packaged. Each package of the goods is intended to have a desired weight. The weighing station (14) comprises a multiplicity of collecting funnels (24) and weighing funnels (25), which are supervised by a central control apparatus. Each individual collecting funnel (24) comprises a housing (30) having a space to receive the goods and an output opening (42) which can be closed by means of two flaps (38, 40). A type of Stephenson III six-link drive is used for opening and closing the flaps (38, 40), the flaps (38, 40) functioning as their output elements. A drive rod (80) controlled with the aid of a control apparatus serves for initiating the input element (4) of the six-link drive for opening the flaps (38, 40). A reset spring (82) is arranged in such a way that it stores potential energy during the opening of the flaps (38, 40) and releases this potential energy during withdrawal of the drive rod (80), in order to guide the flaps (38, 40) back into the closed position. <IMAGE>

Patent DE-4330225-A1 (DE)
Inventor: SCHOECK EBERHARD DIPL ING
IPC: E04G9/08
Filed: 1993-09-07
Abstract: The invention relates to a shuttering board which consists of an essentially rigid basic material and is intended, for example, for clearances in a wall or ceiling region of concrete structural parts. In order to form clearances or the like, such shuttering boards have to be sawn to size and then nailed together. This is expensive and can result in inaccuracies. The invention solves this problem in that the shuttering board is produced from a brittle material which can be bent at prefabricated predetermined bending points (6, 7, 12, 19, 20), a deformable and bendable reinforcement (2, 3, 10) which is integrated in the shuttering board then holding the bent parts together in the desired manner. <IMAGE>

Title: Method and system for monitoring a computer via a telecommunications installation (system) by means of an intelligent unit
Inventor: PAUS STEFAN
IPC: G06F11/273
Filed: 1993-10-01
Abstract: The intelligent unit 5 selects a stored telephone number via a connection to a telecommunications installation 7 if a computer 3 to be monitored has not deactivated the alarm function of the intelligent unit when a specific point in time is reached. To this end, the intelligent unit 5 has a respective connection to the computer 3 and the to the telecommunications installation 7. Furthermore, it contains a clock with an alarm function which is programmed and activated either directly by means of the intelligent unit 5 or by means of the computer 3. If the process to be monitored is processed by the computer 3 without any errors, then afterwards a program to deactivate the alarm can be started. If an error occurs during processing, then the program to deactivate the alarm is not started. When the point in time of the alarm is passed, the intelligent unit 5 emits, via the telecommunications installation 7, an alarm message to the subscriber assigned to the point in time of the alarm. <IMAGE>

Patent DE-4432525-A1 (DE)
Inventor: WALDEMAR HANS DIPL ING
IPC: F16K31/06
Filed: 1994-09-13
Abstract: In prior-art electromagnetically operated fuel-injection valves, a connecting ring (5) made of non-magnetic material is securely fitted between the inner pole (3) and the separately fashioned valve shell (4) to form a tight seal. The manufacture of the high-precision components and fixing the components in place until the tight, secure connection has been produced are time-consuming and costly. The method proposed for the manufacture of a magnetic circuit for a valve is a particularly inexpensive variant using the minimum of materials. The one-piece valve housing (1) has a groove (61) into which the non-magnetic ring (5) is fitted. A pressing die (68) is used to exert a longitudinally acting compressive force on the ring (5), thus displacing material in the ring (5) and in the valve housing (1) radially. Simple machining techniques are then used to remove material form the valve housing (1), starting from an opening (53), until the inner pole (3) and valve shell (4) have been formed from the valve housing (1) as physically distinct components, separated by the ring (5). The magnetic circuit thus produced is particularly suitable for valves in the fuel-injection systems of compression-type spark-ignition internal-combustion engines.

Title: Single=lever mixer tap valve actuator
Inventor: HIRSCH HEINZ
IPC: F16K11/078
Filed: 1994-10-19
Abstract: The disc (45) on the ring (4) can rotate relative to the ring and serves to limit the ring apertures (40) w.r.t. the maximum valve opening as a function of the twist setting. A radial nose (450) on the preferably brass disc is led out of the ring (5) through a slot (42) and the disc can be locked in its setting in the base of the ring bore (43) by a locking ring (46). In the ring area, the disc has an opening with limiting cam (451) to infinitely reduce the lever (22) angle depending on the twist setting of the dis. At the apertures, the disc has an opening complete with stepped rim to set the lever in steps, notably three steps which respectively set the ring apertures to maximum valve flow, flow reduced by 25% and 50% per unit time. The disc can only be twisted round in the ring against resistance to safeguard against unintentional movement.
