Title: Voltage-generating circuit
Inventor: GLEIS DIETER DR ING
IPC: G11C8/00
Filed: 1993-07-23
Granted: 1994-09-22
Abstract: For switching on/off a charge pump or a voltage regulator, a voltage-generating circuit includes a first comparator with a small signal delay and a large power loss and a second comparator with a large signal delay and a small power loss. The output voltage across a storage capacitance is compared in the comparators with a switching threshold in each case, the switching threshold of the first comparator being higher with respect to the output voltage than that of the second comparator. The first comparator has the function of switching the second comparator on and off, the second comparator has the function of controlling the charge pump or the voltage regulator. The fact that the first comparator is switched on only when required means that the circuit has only a low power loss. It is preferably used for generating an increased wordline voltage or a reduced operating voltage for DRAMs. <IMAGE>

Title: Multispeed hub for bicycles
Inventor: MEIER-BURKAMP GERHARD DIPL ING
IPC: B62M11/18
Filed: 1993-12-11
Granted: 1995-02-09
Abstract: The invention relates to a multispeed driving hub for bicycles with or without a backpedal brake, with a hub change-speed gear comprising a first, a second and a differential planetary gear train. A differential ring gear belonging to the differential planetary gear train is connected to a hub sleeve via a coupling device acting in one direction of rotation. The differential sun gear and the second planet carrier of the differential planetary gear train rotate at different rotational speeds depending on the rotational speed of the first and of the second ring gear of the first and of the second planetary gear train, either the differential sun gear or the second planet carrier of the differential planetary gear train turning more rapidly, which has the consequence that the multiplicity of speeds which are produced at the first and second ring gear by the sun gears of the first and second planetary gear train alternately stopping on the hub shaft is passed from said ring gears into the differential planetary gear train. The advantage of hub change-speed gears of this type consists in it being possible to realise a multispeed hub with gear spacings which can be influenced in terms of design as desired. <IMAGE>

Abstract: A press for pressing ceramic masses, in particular for producing roof tiles, has a machine frame (1), a monkey that moves up and down in the machine frame (1) and is provided on its bottom side with one or several top flasks, and a multi-faceted drum (5) with mounting surfaces (10) arranged on a horizontal shaft (140) under the monkey. A number of chases matching the number of top flasks is mounted on the mounting surfaces (10), which are successively moved under the monkey by rotating the drum (5) step-by-step and may be stopped in a position opposite the top flasks. The shaft (140) is mounted with journals (141) in roller bearings (142) of the machine frame (1) and carries between the journals (141) and the multi-faceted drum (5) a cylindrical neck (144) whose outer diameter is larger than the diameter of the journals (141). At least one support (150, 151) is arranged under each neck (144), is in turn supported by the machine frame (1) and has a supporting surface (152) adapted to the curvature of the neck (144), so that the neck is supported over less than half its circumference and is arranged so near the supporting surface that when the monkey is lifted there is at most a narrow gap between the neck (144) and the supporting surface (152).

Title: Anti-theft system for automobile
Inventor: FOERSTL BERNHARD
IPC: G07C9/00
Filed: 1994-08-26
Granted: 1995-10-05
Abstract: An anti-theft system has a portable transponder (2) which carries code information. A stationary oscillating circuit (1, 11, 12) is modulated with the code information if the transponder (2) is located in the vicinity of the oscillating circuit. A demodulator (31) filters the code information out of the modulated oscillation and relays it to an evaluation unit (3) where it is compared with desired code information. Upon correspondence, an immobilizer (34) is released. With system-immanent zero positions which are caused by component tolerances and temperature changes, no desired code information is initially demodulated despite the transponder (2) operating correctly. In this case the oscillating circuit (1, 11, 12) is detuned in accordance with the invention in order to obtain the desired code information. This is achieved by changing the excitation frequency (fE) or the resonant frequency (fR) of the oscillating circuit. <IMAGE>

Title: Remotely controlled speed limiting system for road vehicles
Inventor: WENTZEL JOHAN HENDRIK GERARD
IPC: G08G1/052
Filed: 1995-12-19
Granted: 1997-06-19
Abstract: Each vehicle (1) has a unit (2) under the bonnet which detects the road speed of the vehicle and can prevent the driver from exceeding a maximum speed. The unit receives short range signals from loop antennas (5) buried under the road surface (3). The maximum speed is also indicated on a display (7) in front of the driver. The signal to the buried antenna (5) is generated by a transmitter (4) by the roadside. The transmitter itself receives radio signals from a central control station via another antenna (6). The speed can be set to avoid possible congestion or the risk of multiple vehicle accidents in poor weather conditions.
