Title: Plastics ball bearing nut - is injection moulded with accurately formed thread
Inventor: MOESINGER HEINRICH DR ING
IPC: F16H25/22
Filed: 1991-06-21
Abstract: The nut body is made from a single homogeneous plastics part in which the threads and ball return channel are made in one workstep by casting or injection moulding so that the thread grooves and ball return channel form a closed constantly curved race. The balls are added through bores opening into the return channel. These bores can be formed by a subsequent stock-removing process or at the same time during moulding. The hollow mould has a moulding core with round thread wrapped with an elastic or plastically deformable closed ring of round cross-section so that part of the ring cross-section fills up the negative thread and the other outwardly pointing part of the core forms the grooves for the nut. ADVANTAGE - Economical mass prodn.

Title: Controlling specificity of liq.-solid heterogeneous process - using non-diffusion limited solid matrix, by varying contact time, etc., e.g. for sepn. of albumin from immunoglobulin
Inventor: DEMMER WOLFGANG DR
IPC: C07K14/765
Filed: 1991-07-10
Abstract: The specificity of a particular heterogeneous process, taking place on a matrix, is improved relative to other heterogeneous processes by: (1) using a porous and non-diffusion limited matrix; (2) using a sufficiently short retention time of the liq. phase within the pores of the matrix so as to favour quicker or earlier processes, and (3) making the heterogeneous process depend on absorption, chemical alteration by catalysis or chemical alteration by reaction with the matrix. The processes occur between components of the liq. phase and of the matrix which is permeated convectively by this liq. phase. USE/ADVANTAGE - Typical applications are (1) controlling specificity of sepn. of proteins on ion exchangers by variation of pH and ionic strength and (2) materials sepn; esp. from complex biological fluids, e.g. sepn. of serum albumin (SA) and immunoglobulin (Ig) on a strongly acidic membrane ion exchanger. The method is inexpensive and does not require complex equipment. The use of non-diffusion limited matrix greatly increases the space-time yiel

Inventor: RITTER JOACHIM DIPL ING
IPC: F16D41/08
Filed: 1991-09-06
Abstract: An engageable coupling with a roller freewheel has a pair of rollers (7 and 8) fitted between a ramp-shaped clamping track (6) of an inner component (3) and a smooth cylindrical clamping track (2) of an outer ring (1), whereby the individual rollers (7 and 8) have a compression spring (9) between them which prestresses each roller (7 or 8) towards the end of the ramp-shaped clamping track (2). It is thus possible to transfer a torque between the inner component (3) and the outer ring (1). The coupling can be disengaged because one of the two rollers (7 or 8) can be moved by adjusters (11) against the force of the compression spring (9). The intention is to provide a high torque capacity with a uniform load distribution on the clamping tracks (2 and 6) in such an engageable coupling and to make for compact construction. To this end, there are to be at least three pairs of rollers (7 and 8) evenly spaced around the circumference of the outer ring (1), and the control disc (10) and the inner component (3) are to be carried together in the outer ring (1).

Title: Sensing arrangement for recording marks produced by multicolour rotary printing machine - has photoelectric receivers intercepting light from markers and electronic evaluation system with position measurement system and amplifier gain control
Inventor: LEONHARDT HOLGER
IPC: G01B7/04
Filed: 1992-06-06
Abstract: One or more photoelectric receivers with essentially uniform spectral sensitivity detect the light emanating from the marks on a recording material which is moved w.r.t. the receivers. The receiver signals are amplified and evaluated to determine positional deviations of the marks from their desired positions. An incremental position measurement arrangement for the actual mark positions w.r.t. a reference position can be connected to the evaluation device. The inputs of a comparator in the evaluation device are connected to the amplifier output and to a reference voltage source. The position measurement arrangement feeds the count input of a counter with set and reset inputs controlled centrally. The counter output drives a gain controller followed by a correction unit controlled by the comparator. The correction unit drives the amplifier's control input and a gain controller set input. ADVANTAGE - Accurate detection of rapidly moving recording marks at low cost.

Title: Vehicle central locking system - has secondary lock which must be released within a preset time interval from release of initial lock
Inventor: LINDMAYER MARTIN DIPL ING
IPC: E05B77/48
Filed: 1992-06-06
Abstract: A central locking system for the doors and petrol cap of a car has at least one control position for the lock release using a coded signal, plus a secondary control position to prevent outsider entry, so that full entry is only possible when the secondary lock is released within a certain time interval. There is a timer in the circuitry for the secondary lock which once started, cannot be restarted within the preset time interval, and which returns to its original state at the end of that interval. Both initial and secondary control operations can be by remote control (e.g. infra-red beam). ADVANTAGE - Extra secure central locking system.
Patent DE-4220012-A1 (DE)
Inventor: KERTH DONALD ALLAN
IPC: H03M1/10
Filed: 1992-06-19
Abstract: A ratiometric converter includes first and second A/D converters (36, 38). The latter receives an input signal voltage from a load cell (10) on sense lines (12) and (14) and compares it with an internal reference. Similarly, the first converter (36) receives the reference voltage to the load cell (10) and compares it with the internal reference. The outputs of the converters (36) and (38) are then input to subtraction circuits (78) and (84), respectively, in the digital domain. In a calibration mode, switches (72) and (73) short the reference nodes in the load cell (10) together to determine the non- ratiometric offsets VOFF1-4. These offsets are stored in registers (80) and (86) for the reference and input voltages, respectively. During operation, the offsets are input to subtraction blocks (78) and (84) and a digital subtraction performed on the outputs of both converters. The outputs of the subtraction blocks (78) and (84) are input to a ratio metric operator block (52) to perform a digital division thereon. This results in a ratiometric output that has the non-ratiometric offsets removed. Thereafter, the signal is input to a system calibration block (32) to remove ratiometric errors. <IMAGE>
