Title: Continuous diffusion dyeing process - utilises a cabinet for heat treatment with mechanical loading and manipulation having automatic control
Inventor: KRIMMEL EINAR DIPL ING
IPC: D06B19/00
Filed: 1991-02-02
Abstract: Continuous diffusion dyeing of textiles and carpets utilises a steam heat fixation cabinet with the material held on a frame which can be swivelled and turned through 360 deg. or held horizontally. The appts. is also claimed. The loading equipment is mounted on a track, so that the textile material can be driven into the cabinet by means of pneumatic cylinders. During the heat treatment by steam at 100-103 deg.C, the material is held on a frame, initially in the horizontal position for a period of time. during the fixation period in which movement is required, the frame with the material may be swivelled by hand, manipulated by a large wheel, or driven by an electric motor, which is controlled by a programmed electronic system. This also applies to the timing control for each stage of the process, so that colours may be reproduced exactly. ADVANTAGE - During the heat treatment the steam is fully utilised in the time of application. The equipment requires less space, and the prodn. can be repetitive, with identical results.

Title: Data direction control for half-duplex bidirectional transmission - involves recognition and storage of direction in trigger circuit while contrary traffic is blocked by logic
Inventor: GRABNER JENS-HAGEN
IPC: H04L5/16
Filed: 1991-04-23
Abstract: The direction and duration of data flow are determined by a D flip-flop (D1) and a retriggerable monostable multivibrator (M1) respectively. AND-gates (G1,G2,G4) and OR-gates (G3,G5) ensure that during reception of data (RxDA) from one medium (A) the input channel (E2) for reception (RxDB) from the other medium (B) is blocked and vice versa. No reversal takes place until after both input channels (E1,E2) have reverted to high potential for transmission requests (RTSA,RTSB) to the respective output channels (A1,A2). ADVANTAGE - Bidirectional half-duplex transmission over async. network is possible with only one transmitter active, and operation is software-independent.

Inventor: BRAEHLER UWE DIPL ING
IPC: H04N17/00
Filed: 1991-05-10
Abstract: In a method of measuring frame position errors in film scanning a plurality of comparison values is generated by comparing 10-13 pixels of one column of a frame with pixels of the same column of a time-adjacent frame, while the pixels to be compared are vertically offset 7-9 with respect to each other from comparison value to comparison value. The vertical offset whose comparison values assumes an extreme value relative to the other comparison values is defined as the frame position error. <IMAGE>

Title: Futuristic electric vehicle - uses inductive pick=up from cable buried in street surface through tyres or subframe and homopolar motor
Inventor: GRESSER GERMAN
IPC: B60L9/00
Filed: 1991-05-13
Abstract: There are various ways of supplying an electric vehicle with external power from a cable buried in the street surface (1).

Patent DE-4233546-A1 (DE)
Inventor: HOFFMANN GOTTFRIED DIPL ING
IPC: B61L1/16
Filed: 1992-10-01
Abstract: Correction of the counter result (18) of a counting point (Z3) by the corresponding counter results (20) of neighbouring counting points (Z2, Z4) is permissible only if a further check has been made to ensure that the sections between these counting points which have been signalled as still occupied as a result of the counting difference are actually free; this is preferably done by comparing the counting results of other counting points (Z1, Z5) on either side of the faulty point (Z3). To correct counting errors also in the section containing branched lines, counter results are allocated to all lines in these sections. The free signal conditions for these sections are used to find free signal equations and from the two free signal equations for each counting point is found a correction equation which establishes the condition in which a counter result may be regarded as clearly false and correctable. The counter results are processed in computers which retain the axle counts of the counting points which they passed for each train. The counting point information is allocated to the storage fields in the computers for the individual trains by the concatenation of the counting points by the free signal equations applicable to them.
