Patent DE-3324884-A1 (DE)
Title: Bumper for deflecting centrifugal forces
IPC: B60R19/26
Filed: 1983-07-09
Abstract: It is known that vehicle collisions have devastating effects since the centrifugal forces of the two masses interact with one another violently. Since the centrifugal forces cannot be eliminated, they must be deflected laterally. This is possible if the bumpers, which are built on at the front over a width of for example 80 cm, can deflect as in the figure. The springs and streamlined panelling ensure that only the impact forces during collision cause the bumper to be deflected. The streamlined panelling also ensures that the slipstream does not get caught between the bumper and the vehicle in an energy-absorbing fashion. A lubricant which is located below a thin skin of the bumper or is pressed out of the bumper from nozzles in the event of an impact, ensures that the vehicles which have collided slide away from one another with a low degree of friction. The pyramid which permits the bumper to be deflected has to be in the right-hand half of the width of the vehicle because most accidents act on the left-hand side, but must not however be on the right-hand edge of the vehicle since right-hand side collisions permit slipping off as a result of the bumper which has swivelled off to the right. <IMAGE>
Patent DE-3326040-A1 (DE)
Inventor: DAAR HORST DR ING
IPC: B03C3/76
Filed: 1983-07-20
Abstract: A method for operationally determining the existence of an optimal rapping interval for the collector electrodes of an electrostatic precipitator comprises the comparison of the current-voltage characteristics for precipitator operation under pure-gas conditions and actual use conditions. If the comparison indicates that the resistance of accumulated dust layers is greater than the resistance of air, then an optimal rapping interval exists. This interval may be calculated analytically or approximated by means of an iterative process.

Title: Automatic for forming the thread on nuts
Inventor: IVANOV VELIKO KOLEV
IPC: B23G1/16
Filed: 1983-10-20
Abstract: The invention relates to an automatic for forming the thread on nuts. It is intended for the use of taps with a short connecting part or of cold-forming taps. The automatic according to the invention guarantees a high, variable cutting speed which is minimal at the moment the tap cuts into the material and then changes according to a certain law. Used on each spindle of the automatic are two taps attached to both ends of the same, one tap making the thread when the other tap is being screwed out of the thread already cut. This ensures a high productive capacity of the automatic and the production of multi-spindle automatics. The automatic is composed of reduction gearing (27, 28), discs (10, 13) with eccentric journals which are connected to four-bar articulated mechanisms, differential gearing, consisting of the above-mentioned four-bar mechanisms and gear blocks (20, 22), and a central gearwheel (21) which meshes with a gearwheel (24) attached to the spindle (6). <IMAGE>

Abstract: The invention relates to a device for viewing stereoscopic images, in particular stereoscopic projections of slides, films and the like, using polarising filters, and aims to facilitate three-dimensional vision which is free from interference, clear, sharp and over a wide area, and the achievement of a considerable improvement in quality of the image or film to be viewed. For this purpose, a device is proposed in which two mutually connected, convex polarising filter discs or sheets, which essentially embrace the field of view of a viewer and have axes of polarisation rotated by 90 DEG  with respect to one another, are provided in the region of their connection with constrictions in a direction towards the nose/forehead of the viewer. <IMAGE>
Patent DE-3347045-A1 (DE)
Inventor: HEROLD JULIUS DR
IPC: C08G18/48
Filed: 1983-12-24
Abstract: The invention relates to two-component polyurethane adhesive preparations in which the resin component is an oleochemical polyol. The oleochemical polyols used are ring-opened products of the reaction of epoxidized fatty alcohols, fatty acid esters (particularly triglycerides) or fatty acid amides with alcohols. The oleochemical polyols may be varied within wide limits in regard to their OH-functionality and so formulated with the hardener polyisocyanate components that the adhesives satisfy the relevant requirements. Reaction products of epoxidized triglycerides with monohydric alcohols are a particularly effective substitute for castor oil.
Patent DE-3347431-A1 (DE)
Title: Locking circuit for phase-locked loops (PLL)
Inventor: MARDUS CLAUS
IPC: H03L7/10
Filed: 1983-12-29
Abstract: A locking circuit for phase-locked loops is proposed which is used for enabling phase-locked loops to lock more rapidly to a nominal frequency. For this purpose, the phase-locked loop, in the idle state, that is to say when there is no nominal signal (useful signal) to be synchronised, is supplied with an auxiliary signal which locks the phase-locked loop to the approximate frequency which the useful signal to be expected later will have from experience. This makes it possible for the phase-locked loop to lock in in a shorter time or, respectively, to become synchronised more rapidly. <IMAGE>

Title: Apparatus for crushing stones in body cavities and for use in HF surgery
Inventor: WURSTER HELMUT DIPL ING
IPC: A61B18/00
Filed: 1984-07-26
Abstract: Devices for crushing stones in body cavities and for use in HF surgery with an electrical generator have at least one socket into which different probes having a plug assigned to them can be plugged at choice. Each particular probe is assigned specific operational values which have hitherto been adjusted manually on the apparatus, and this has led to operational errors with very disadvantageous consequences for the patient, the apparatus itself and the operator. This possibility of operational errors is avoided in the apparatus described in the present patent in that at least one plug connection present between each probe and the generator is encoded in such a way that the operational values of the generator are automatically adjusted to the respective operational values of the particular probe by production of this plug connection.

Title: Circuit arrangement for preventing switch-off voltage peaks
Inventor: KOPETZKY HORST DIPL ING
IPC: H03K17/0814
Filed: 1984-09-25
Abstract: When pulse-shaped currents are applied to an inductance, switch-off voltage peaks occur which can lead to destruction even when the pulse-shaped currents are produced by operating an electronic switch. Such effects are prevented by a diode (D1,D2) being connected to one terminal of the inductance (W1,W2), in series with which diode a capacitor (C1,C2) is connected, that an ohmic resistor (R1,R2) is connected between the junction of diode and capacitor and the other terminal of the inductance, and that the diode is polarised and biased in such a manner that it is only conductive during the period of the switch-off voltage induced by the inductance due to the interruption of the current flow so that a charging current for the capacitor can flow via this diode and the entire discharge current of the capacitor flows via the said resistor. <IMAGE>
