Title: Process for producing microscreens from polyvinylidene fluoride
Inventor: BRANDT REINHARD PROF DR
IPC: B29D99/00
Filed: 1986-07-10
Abstract: Heavy-ion bombardment of an extremely heat-resistant and chemically resistant plastic film of polyvinylidene fluoride, with subsequent etching, is used to produce microscreens. These microscreens are typical nuclear track filters with well-defined holes. The hole size may be optimally selected between 0.1  mu m and 50  mu m; the hole size depends on the etching conditions, in particular on the etching, and on the etching temperature. These nuclear trace filters of polyvinylidene fluoride are intended to be very useful in environmental protection under extreme conditions.

Title: Device for speed limiting
Inventor: OTTOSSON LARS-OLOF
IPC: F02P1/08
Filed: 1986-09-05
Abstract: The subject of the invention is a device consisting of charging and trigger circuits to achieve speed limitation in conjunction with a flywheel covered with magnets and a capacitor ignition system. The invention has the effect that the circuit (10, 11, 13, 14, 9) charging the capacitor (12) loads the charging voltage source (6) present in such a way that the voltage pulses produced are temporally shifted as a function of the speed. The voltage source (8) of the trigger circuit has to remain essentially unloaded in this circuit. In the case of a particular boundary speed, the charging voltage pulses reach a particular degree of shift and influence the ignition operation via the control circuit (26) in such a way that there is no spark formation (Figure 2). <IMAGE>
Patent DE-3633671-A1 (DE)
Title: Method of fuel injection
Inventor: HANNEWALD THOMAS
IPC: F02D41/14
Filed: 1986-10-03
Abstract: In a method for the injection of fuel in spark-ignition engines, the injection quantity being controlled by means of a lambda probe in the exhaust port, the output signal of the exhaust probe is sequentially analysed and the value of the output signal occurring during the respective time span is used to control the injection quantity of the particular injection valve which is assigned to that cylinder whose exhaust gases give rise to the output signal in the respective time span. At the same time, a mean injection quantity can be obtained by analysing an output signal in each case averaged over at least one working cycle of the spark-ignition engine and correction values determined by analysing the values of the output signal occurring in the individual time spans and these correction values superimposed on the value for the respective mean injection quantity.

Patent DE-3701172-A1 (DE)
Inventor: KANDLER GEORG
IPC: F16M11/06
Filed: 1987-01-16
Abstract: A supporting stand has arms and linking joints designed in such a manner that each arm is formed in a single piece with the corresponding joint halves. When the form of the stand needs to be changed, the two joints delimiting an arm are dismantled and the arm with its joint halves is exchanged. This process is labour-intensive and requires a great diversity of parts for modifying the stand. In order to allow the form of a stand to be changed in a simple manner, the stand has a joint (4, 6) made of two joint halves (7, 8) movable relative to each other and of which at least one is linked to an arm (3, 5). In order to allow for variability, each joint half (7, 8) linked to an arm (3, 5) has a projection (20, 21) that can be detachably linked like a plug with an arm (3, 5). The stand is particularly suitable as a ceiling stand for intensive care units, operating theatres and the like.

Patent DE-3713287-A1 (DE)
Inventor: ERBERT KARL
IPC: A45D26/00
Filed: 1987-04-18
Abstract: In the depilating device, the clamping device for the removal of hairs consists of a tweezer block (32) with about 10 to 60 parallel slats which can be spread apart by a drive apparatus (13) to oscillate periodically at a frequency of about 2000 to 15000 min<-><1> and can be braced against one another after the intake of hairs. The tweezer block (32) is also moved by the drive apparatus (13) back and forth between a clamping position, which lies near to a support apparatus, and the spread apart position which is remote from said support apparatus. In this case, a superimposed, oscillating swivel movement of the tweezer block (32) takes place about an axis which extends perpendicular to the axis of symmetry of the tweezer block (32) and parallel to the spreading direction of the slats. By this means, an assumed point on the free end of the slats executes a movement, the path of which extends approximately on a rectangle. By this means, the hairs are taken in more easily prior to removal and then knocked out. The arrangement is accommodated with the support apparatus in a handy housing. <IMAGE>

Abstract: A device for measuring the depth of the gingival troughs (5) in case of paradontopathy, in particular for preparing a paradontopathic report, enables this report to be prepared more rapidly and deviates the need for an assistant. The essential component of the device is a probe (6) which is provided with an external row of light-sensitive cells or which consists of a transparent canula containing light-sensitive cells which can be displaced along its length. The edge of the gum is determined spatially from the difference between the illumination inside and that outside the gingival trough (5). The depth of the trough is thereby determined with respect to the tip of the probe (6) and automatically recorded. The handle (9) of the probe may contain an actuating member for initiation of the reading process.
