Title: Brake operating device for hydraulic vehicle brake system - has main brake cylinder with two pressure chambers in steel tube housings.
Inventor: SCHONLAU JUERGEN
IPC: B60T13/565
Filed: 1991-06-28
Abstract: The device consists of pneumatic brake force intensifier, pref. underpressure intensifier, and a main brake cylinder arrangement.

The intersection of the effective lines of the reaction forces, resulting from the hydraulic pressure in the chambers, with the symmetrical axis (40) of the brake force intensifier (1), is located within the fastening range of the actuating rod (5) on the brake pedal (3). ADVANTAGE - Cheap, problem-free handling of reaction forces.
Patent DE-4125424-A1 (DE)
Inventor: GUSKO ACHIM DIPL PHYS
IPC: G01F1/84
Filed: 1991-07-31
Abstract: The invention concerns a mass flow meter for flowing media which operates on the Coriolis principle. The meter has a pipe inlet (1), a pipe (2) which conveys the flowing medium, a pipe outlet (3), a pipe drive (4) which imparts a rotational movement to the pipe and a measurement device (5) for measuring the Coriolis forces. The pipe (2) is arranged in a rotor (7) designed as a rigid body which is rotatably mounted with two or three degrees of rotational freedom in a stator (9) and driven about a shaft (6) fixed to the stator. The rotor (7) therefore forms a gyroscope to which a precessional movement, which can be evaluated by measurement methods, is imparted by the Coriolis forces.

Title: Photovoltaic element for solar module
Inventor: DORISON ANDREAS
IPC: H01L31/05
Filed: 1991-12-21
Abstract: The appts. tests a multiplexer separating an input string into 2k outputs. A test pulse string generator and a pulse error measuring device, using the generator clock frequency divided down to 1/2k, generate a same pattern first 2k-1 bit period M-sequence and respectively shift it m-bits and p-bits to obtain a second M-sequence.      Test and reference pulse strings of the desired mark ratio are logically derived from the respective M-sequence pairs. A mismatch detector compares reference and demultiplexer output strings on a bitwise basis to satisfy p = (m+v(2N-1))/2k, where m, p, k, N are positive integers and V is a desired integer.

Title: Dividing fluid flow into different uniform streams - involves different throttles for opening and throttling various outlets in permanent sequence.
Inventor: ALTMAYER GERHARD DR ING
IPC: F27D3/00
Filed: 1992-04-21
Abstract: Only one outlet is fully opened at any one time. The throttles can be produced by one rotary disc (12) which is common for all the outlets (7) but has different opening widths (17-22) or openings of different size set in the same angular symmetrical arrangement as the outlets (7). The disc is turned stepwise so that each next smallest opening lies in front of the outlet, and after the smallest opening then the largest. The outlets are fully opened in succession through the suitably dimensioned largest opening and then throttled increasingly with the smaller openings. USE/ADVANTAGE - A flow is always maintained in the relevant branch line reducing the risk of blockages.
Patent DE-4216151-A1 (DE)
Inventor: HERTRAMPF MICHAEL DR MED
IPC: B65D41/04
Filed: 1992-05-15
Abstract: A screw top for sealing a bottle or the like has a pressure control valve formed between the screw top and the lip (9) of the bottle neck (5). A limit stop is formed between a stop face (12) on the inner wall (10) of the screw part (2) and set in the unscrew direction of the screw part (2) and a counterstop face (13) around the perimeter of the bottle neck (5) and set counter to the unscrew direction of the screw part (2). The stop faces are arranged in such a way that they press together in the circumferential direction when the desired load force of the sealing surface on the lip of the bottle neck has been reached, with said load force determining excess pressure release. Thus, unscrewing the screw top is limited by limiting the rotary movement of the screw top. The attendant stopping forces are not amplified by the pitch of the screw thread, and so damage to the limit stop is avoided.

Title: Authenticity checking of coins using inductive effect - in which resonance is triggered in coil to provide signal for comparison to generate pulse of width specific to coin
Inventor: MULDER ARJEN JOHAN DIPL ING
IPC: G07D5/08
Filed: 1992-07-22
Abstract: A sensor system is built into a guide channel along which coins are rolled. Built into the channel is an electromagnetic coil (10) with resistance and inductance. The field is activated by switching an FET (11) and a voltage regulator maintains a constant supply voltage. The presence of a metallic coil causes a voltage to be induced that is applied to an amplifier (1) that has integrator (2) feedback. The generated ringing pulses of the induced voltage have a shorter period than the integrator time constant. The pulses are amplified and fed to a comparator (3) for comparison with a reference voltage VREF. The period of the outpt is used to access a set of tabulated values to identify the coin. USE/ADVANTAGE - Simple and reliable identification process.

Title: Line image generator for computer graphics - uses three registers, adder and selector to generate line data relating to pattern of segment
Inventor: ITO KAZUMASA
IPC: G06T11/20
Filed: 1992-08-21
Abstract: The line image generator includes a register (12) for storing information relating to the pattern of a segment.

The relationship is variable in each region of the pattern. A third register (15) holds separate data which are expressed by a fixed decimal point in an instantaneous region of the pattern. The two data are added (14) and the result is fed to the third register (15). A selector (16) choses the output of the first register (12) in accordance with the content of the third register, which was replaced by the output signal of the adder (14). ADVANTAGE - Pattern of lines is not influenced by their inclinations.
