Patent DE-4234788-A1 (DE)
Title: Laser tool - with a distance measuring unit incorporating a pneumatic sensor for determining the pressure produced by a gas jet
Inventor: SCHMID DIETMAR PROF DR ING
IPC: B23K26/14
Filed: 1992-10-15
Abstract: The laser tool incorporates a measuring unit (21) for determining the distance between the tool and a workpiece. Signals from this unit are utilised by a distance control system. The measuring unit (21) includes a pneumatic sensor (23) for determining the pressure produced by a gas jet during approach of the tool to the workpiece. The gas jet emerges through an annular gap (11) surrounding the exit opening (25) for the laser beam. It can also emerge from an annular gap (19) which is functionally connected to the sensor (23). The exits from the gaps (11) and (19) are located at a level (E1), while the beam exit is located at a level (E2) which is closer to the workpiece. USE/ADVANTAGE - In laser cutting and welding installations. Distance between the tool and workpiece is accurately maintainable for any workpiece material. The small size of the tool allows it to be used without special measures on small workpieces.

Title: Method for the elimination of the reflective element of light radiation reflected from an object
Inventor: KASRAVI KAMBIZ
IPC: G01S7/497
Filed: 1993-02-13
Abstract: By the elimination of the signal element returning after being reflected, the new method is intended to enhance the security of, for example, driverless transportation vehicles and similar devices, such that people or objects who or which reflect diffuse light are identified without any doubt. Depending on the scanning process (sampling process), a probing transmitted light beam is emitted which has a low transmitted power (which prevents diffuse reflection) and whose current intensity (ISP) is stored. If a return signal is received, both output currents from the position sensor (14) are measured and stored. The main transmitted light beam is then emitted using the transmitting current (ISH) and the current elements (IF3, IN3) produced in the position sensor (14) by the reflectively reflected element are calculated from the current intensities (ISP, ISH) of the probing and main transmitted light beams and from the output currents (IF1, IN1), generated by the probing return signal, from the position sensor (14). The current elements (IF2, IN2) produced by diffuse reflection are then obtained and evaluated by subtraction of the reflected current elements (IF3, IN3) from the total output currents (IF2, IN2) from the position sensor (14). <IMAGE>

Title: Process for feeding and loading of plastics sections
Inventor: KREISL REINHARD
IPC: B29C65/78
Filed: 1993-03-04
Abstract: A turning device receives the sections to be welded, for example plastics sections or window frames, from a position in a magazine one after the other and, if appropriate, also on more than one level. The sections lie parallel to one another in the magazine. After being received, the sections are in each case turned by the turning device and/or raised or lowered. After the sections have been received by the turning device, they are fed to the frame welding machine and are loaded into holders of the frame welding machine.

Title: Wheel nut with integral flange - has concave flange face and is solid-shaped, e.g. by cold or hot-pressing and has clamping portion with tapering bore and slots
Inventor: BAECHLE EWALD
IPC: B21H3/08
Filed: 1993-03-06
Abstract: The nut has a polygonal spanner portion and an integral flange or pressure-plate. The face (4a) of the flange bearing against the wheel is concave and it is solid-shaped, e.g. by cold and/or hot-pressing. The cross-section, radial dimension, concave curvature and material of the flange can be so selected that on tightening the nut elastic but not plastic distortion of the flange takes place. A clamping portion with a wall thinner than the main part can be formed on the nut end furthest from the flange, having a tapering bore and being slotted in the axial direction. ADVANTAGE - Accommodates angular discrepancies and gives more even pressure distribution, with consequently less tendency to work loose.

Title: Circuit arrangement for limiting the amplitude of a useful signal
Inventor: BRILKA JOACHIM
IPC: H03G7/06
Filed: 1993-04-10
Abstract: In the circuit arrangement according to the invention for limiting the amplitude of a useful signal, the customary overmodulation (overdriving) of an amplifier characteristic for the purpose of limiting the amplitude is avoided. The circuit arrangement according to the invention is characterised to this end by a multiplying stage (9), to which the useful signal (at 1) can be fed at a first input (8), and a rectifier stage (12) for forming a control signal (at 19, 20), which corresponds to the magnitude of the useful signal and can be fed to the multiplying stage (9) at a second input (19, 20), which has an input characteristic shaped in accordance with the tanh function, as a result of which, when the instantaneous values of the useful signal are multiplied by those of the control signal, an output signal (UA, at 22, 23) is produced, which has the frequency of the useful signal and an amplitude which is at least to a large extent constant. <IMAGE>

Title: Inhibitors for the zymogen-like liberation cleavage of HIV-1 protease
Inventor: LINDHOFER HORST DR
IPC: C07K7/02
Filed: 1993-09-23
Abstract: Because the gag-pol dimer, which is evidently responsible for the initial proteolytic activity, has a substrate specificity which differs slightly from the mature PR (or at least different catalytic constants), conventional PR inhibitors are not able to inhibit it optimally. The aim therefore is to find inhibitors which are able to inhibit specifically the initial cuts in the gag-pol polyprotein. The inhibitors described herein are based on two amino-acid sequences which are initially cut in the gag-pol polyprotein and differ in essential positions from the cleavage sites which are cleaved by the mature HIV-1 protease. The two amino-acid sequences suitable and preferred as cleavage sites of a proteolytically active gag-pol dimer are:  P4 P3 P2 P1 P1' P2' P3'  Arg-Gln-Ala-Asn * Phe-Leu-Arg  Asp-Leu-Ala-Phe * Pro-Gln-Gly. The following inhibitors can be derived from these: <IMAGE>   The underlined groups are merely examples and can be replaced by groups of comparable function. Use of the inhibitors as pharmaceuticals for inhibiting the replication of HIV-1 in infected people.

IPC: F02M35/08
Filed: 1994-04-20
Abstract: An air filter for an internal combustion engine is proposed. The said filter has a filter insert which is arranged on a housing. A clean-air outlet and an untreated-air inlet are located on the said housing. The untreated-air inlet is provided with a screen (17). A further untreated-air inlet (18) is also provided, which has a flap (19). In the normal operating condition the said flap (19) closes the untreated-air inlet (18).
