Patent DE-4026698-A1 (DE)
Inventor: DAHLIN JAN ERIK AAKE STEINAR
IPC: H04L9/12
Filed: 1990-08-23
Abstract: A synchronizing method in a mobile radio system which operates with Time Division Multiple Access (TDMA) but which lacks global time reference for all base stations and mobiles in the system. The inventive method is intended for ciphered transmission of data and speech in accordance with a given ciphering key (E2). When handing-over a call, the ciphering synchronism is lost. In accordance with the method, subsequent to hand-off (the time t2), the take-over base station (BS2) signals non-ciphered information (S1) to the mobile (MS) disclosing the number of frames (R1-R13) which shall pass until ciphering can again be commenced, calculated from a given frame (R1). Call information is transmitted in the following frame (R2), this information now being ciphered with the aid of a ciphering key (E1) different to the original key. This other ciphering key consists of a periodic bit sequence having a period which is equal to one frame interval.

Patent DE-4119834-A1 (DE)
Inventor: KEMNER AXEL DIPL ING
IPC: H02K21/14
Filed: 1991-06-12
Abstract: The invention relates to a method for generating electrical energy from the rotational movement of the axles of vehicles, in particular rail-bound vehicles, by means of a generator arrangement in which in addition to the generation of electrical energy the speed of rotation of the respective axis is determined. In order to provide a method for operating an axle generator arrangement and an axle generator arrangement itself as well as a use of the same which is matched thereto, with which method a separate angle of rotation sensor can be dispensed with and a safe and reliable supply of energy with as constant electrical voltage as possible is ensured in all operating situations, it is proposed that both the generation of electrical energy and the determination of the speed of rotation should take place exclusively by a generator function, the pulse parameters of each induced electrical voltage characteristic being evaluated in order to determine the speed of rotation.

An expansion volume is located above the fuel tank and below a level, which is determined by max. volume level in the top section of the filler pipe. A float valve (7) is located above expansion volume (2). The valve forms a connection between expansion volume and the environment (45), when the fuel volume in the tank (1) has reached a certain level. The connection is blocked by the valve, while the tank is being filled. ADVANTAGE - Expansion volume is not filled while tank is being filled, but may be filled after this process has been completed.

Title: Speed regulator for motor vehicle - controls throttle position dependent on speed error and uses filtered feedback signal for stable regulation by adjusting signal level
Inventor: CASPARI CHRISTOPH
IPC: G05B7/02
Filed: 1991-07-15
Abstract: The electronic control unit (10) has a regulator (1) that compares the actual vehicle speed with a stored reference value and generates an output to adjust the throttle (4) of the fuelling system. The throttle position is monitored by a potentiometer (5) and feedback is generated via an A/D converter (11) to a low pass filter (12) that prevents minor fluctuations having an effect. The filter output, together with the acceleration values obtained by differentiating (13) the tacho speed signals (7), is used to obtain control values from a table (14) used by the regulator to obtain a stable setting.

The blocking device (15, 15a, 15b) comprises a blocking bolt (18, 18b) displaceable perpendicularly to the axis of the cylinder core (6), engaging into a recess (20, 20b) of the cylinder core (6) for securing the cylinder core (6) and moveable out of the cylinder-core recess (20, 20b) for releasing the cylinder core (6), an electromagnetic coil (23, 23b) and an armature (24, 24a, 24b) which is mounted in the cylinder housing (2) displaceably between a blocking position and a release position and is moveable by means of the coil (23, 23b) and which, in its blocking position, blocks the blocking bolt (18, 18b) and, in its release position, releases the blocking bolt (18, 18b). In one embodiment, during the rotation of the cylinder core (6) out of the locked position, the released blocking bolt (18, 18b) is shifted out of the cylinder-core recess by the cylinder core (6). In another embodiment of the invention, the blocking bolt (18) for securing the cylinder core (6) is shifted by the armature (24) when the latter is moved into the blocking position. The lock cylinder can be produced simply and cheaply and requires only a small number of parts. <IMAGE>

Title: Feed head for automatic screwdriver, etc. - has screws fed into tool chamber via swivelling tube with spring-loaded hinge
Inventor: BABACEK MICHAEL
IPC: B23P19/00
Filed: 1991-10-09
Abstract: Screws or similar fasteners are guided through feed tube (3) and feed tube extension (1) into the chamber (19) of the automatic screwdriver.
