Title: Protein sub-unit thin layer gel electrophoresis - using plastic foil coated with poly:acrylamide gel contg. alkyl-substd. urea deriv. as chaotropic agents
Inventor: GRUBHOFER NIKOLAUS DR
IPC: G01N27/447
Filed: 1980-08-26
Abstract: In a new procedure for the analysis of protein subunits by means of thin-layer electrophoresis using aq. polyacrylamide, gels coated onto elastic foils, the gels contain substd. urea derivs. in which the H-atoms are wholly or partially replaced by 1-4C alkyl gps. The urea derivs. exert a chaotropic effect on protein molecules, but do not form cyanate ions in water and do not crystallise out at low-temps. They are effective at lower concns. than previous chaotropic agents; thus, tetramethylurea in a concn. of only 50 g/l causes complete dissociation of haemoglobin into its subunits.

Patent DE-3101631-A1 (DE)
Title: Automatically clamping rope-clamping device
Inventor: KIRSCHBAUM RAINER DIPL ING
IPC: B61B12/12
Filed: 1981-01-19
Abstract: The clamping device developed by me affords the following decisive advantages over previous clamping appliances:     a) a theoretical 90 DEG  climbing ability   b) high economy   c) lower individual weight   d) silent   e) long life time   f) easy to maintain   g) as little stress as possible on the hauling rope   h) high rope speed   i) infinitely high clamping safety, with self-locking occurring   j) very easy and harmless coupling and uncoupling.   The range of use extends to all sectors where forces are to be absorbed by a rope strand or round bar, but the force engagement point on the rope strand is often to be changed arbitrarily. Clamping takes place as a result of the occurrence of self-locking when force is exerted. Release takes place by means of the partially toothed clamping arms via a lever to be attached on bolts (8). <IMAGE>

Patent DE-3118979-A1 (DE)
Title: Pig pen for accommodating pigs
Inventor: BOEDECKER WALTER
IPC: A01K1/02
Filed: 1981-05-09
Abstract: The problem with pig pens, for accommodating pigs, is that urine and excrement collect on the ground. This is particularly disadvantageous in farrowing pens for sows because urine and excrement can then pass to their teats. In order to provide a remedy for this there is arranged, at the trough end of the pig pen, in the upper region thereof, a transversely running rod (8) which can be adjusted horizontally in the longitudinal direction of the pig pen and vertically thereto. According to experience, the pigs go up to the trough at the front for defecating and urinating and then assume a bent posture. If the abovementioned transverse rod prevents the pigs from taking up this bent posture, they move backwards until they are able to assume the abovementioned, specific posture, and only then do they urinate or defecate. This results in a clean division between the bedding-down region and the excrement region within the pig pen, and the teats of the sow are consequently kept free of urine and excrement. <IMAGE>
Patent DE-3119665-A1 (DE)
Title: Programming switch unit
Inventor: BERGMANN ALBERT ING GRAD
IPC: H01H43/10
Filed: 1981-05-16
Abstract: The invention relates to a programming switch unit having a cam drum which can be driven at different rotational speeds via a control switch and a driving device which can be influenced by this. At the same time, there is a preselection disc, of which the rotary-angle position relative to the cam drum can be adjusted by hand via a ratchet mechanism dependent on the direction of rotation, whilst the control switch can be actuated by a setting device of the ratchet mechanism. The setting device has a plurality of lifting pieces (13) in the form of an arc of a circle, which are held radially adjustably on the preselection disc and which are arranged in an approximately closed circle concentrically relative to a slotted ring (11) in the form of an arc of a circle and connected in one piece to the cam drum. Located on the lifting pieces (13) are radially directed lifting-out cams, each with a sloping edge, which drop into matching recesses (26) of the slotted ring (11) and which are deflected radially outwards via the sloping edges as a result of a relative displacement between the preselection disc and the cam drum (3). The control switch is thereby changed over. <IMAGE>

Title: Method and device for the controllable projection of a light beam using two movable mirrors
Inventor: BLASCHE KLAUS DIPL PHYS DR
IPC: H05K13/00
Filed: 1981-06-27
Abstract: The method and device for the controllable projection of a light beam using two movable mirrors are suitable in particular, but not exclusively, in the case of devices for fitting (assembling) circuits or printed circuit boards. The method and the device can be used for a fault-free projection of a light beam simply by inputting coordinate values or deflection angles, due to the fact that geometrical imaging errors (aberrations) are corrected, the gain of an amplifier for the control voltages of the movable mirrors is varied as a function of the sign of the mirror control voltage, and zero-point shifts and deflection deviations which occur when the beam is imaged and can be caused by temperature influences are compensated. Arrangements are specified for carrying out the method. <IMAGE>
