Patent DE-4237520-A1 (DE)
Title: Femur epiphysis fixation threaded pin - has thread of such configuration that it can engage only spongiosis of joint neck, or femur
Inventor: KUMM DIETMAR A DR MED
IPC: A61B17/74
Filed: 1992-11-06
Abstract: The threaded fin has a self-taping outer thread with a larger rated dia. than the pin itself, so called spongiosis thread. The thread is of such configuration and arrangement that it engages only the spongiosis of the joint neck, or the femur. Pref., the thread lies between the fixation pin head and the adjacent 2/3 of the pin length. The pin may have a centre bore (cannula). The firm head has a recess, such as a hexagonal socket head, or slit. ADVANTAGE - Increased service life, easy positioning and simple handling.
Patent DE-4244722-A1 (DE)
Title: Reduction in the power dissipation in push-pull amplifiers by suppressing some of the supply voltage
Inventor: SCHROEDEL GERHARD
IPC: H03F1/32
Filed: 1992-03-10
Abstract: A "first order supply voltage suppression" in the form of an automatic switch-over system which relates to a bipolar power supply ensures that the pole half which is not needed for the current polarity of a half wave is switched off. As a result, power dissipation can be saved which, due to the phase angle of the load impedance, is caused in the other control stage in each case during a load current flowing with the opposite polarity. During operation with a purely resistive load, this supply voltage suppression is ineffective. A "second- or higher-order supply voltage suppression" in the form of an automatic switch-over system which relates to a bipolar power supply, the two pole sides are subdivided into in each case two or more independent series-connected supply voltages, ensures that the operating voltage components not required for modulating the output stages are switched off (suppressed). In these circuits, the reduction in power dissipation also becomes effective with purely resistive loads but especially with reactive loads.

Title: Method for colouring optical waveguides
Inventor: SHUBBAR ABDUL AMIR RADHI
IPC: C03C25/1065
Filed: 1993-02-17
Abstract: A method for colouring primary-coated optical waveguides in a continuously running equipment, the colour being applied by immersion and then fixed by means of UV light, characterised in that the speed of the passage is regulated as a function of the fluctuations of the external diameter of the fibre. This takes place by means of measuring the total diameter of the fibre after the treatment. For controlling the speed of the process sequence, the input of the measuring variables into a data processing unit is carried out continuously. At the same time, reporting is carried out, which serves the purpose of making the production sequence transparent.

Title: Paper web coating blade - has a reflected for light beam as monitor for control of blade pressure bar setting
Inventor: KUSTERMANN MARTIN DR
IPC: B05C11/04
Filed: 1993-04-28
Abstract: In the assembly to coat a moving web of paper or cardboard, the spreader blade (2) is pressed against the roller (R) and web at least additionally by a pressure bar (5) or several pressure units. A light transmittter (9), especially a laser beam (12) is directed at a reflector surface (8) at the blade (2) to reflect the light beam (12). A receiver (10) registers the angle of reflected light (13) from the surface (8) at the blade (2) for a control system to set the position of the blade (2) by adjusting the pressure bar (5) according to the light receiver (10) signals. Pref. the pressure bar (5) is relatively pliable across the blade (2). The pressure applied by the bar (5) on the blade (2) can be set at local points across the blade (2) width. The light reflection surface (8) is a film, with magnet plates or strips as a carrier (7) to hold it against the blade (2), in a wedge shape to give the incoming and reflected light angles, with adjustment on the contact line of the blade (2) at the roller (R). The light reflection surface (8) ncan also be a glass mirror plate with a max. size of 25 mm2. Th weight of the film and the light reflection layer (8) is max. 50 g/m2. USE/ADVANTAGE - The appts. is for applying a dosed coating to a paper or cardboard web, or by applying the coating to a roller for transfer to the web. The monitoring system avoids the use of a sensor with a noticeable weight, and the blade and monitor can be exchanged rapidly.

Title: Process and device for the continuous production of lactic acid
Inventor: PUTH HANS-EDGAR
IPC: C12P7/56
Filed: 1993-05-21
Abstract: Lactobacillus growth and acid production has to date preferably taken place in batches and/or using a plurality of tanks. The process is intended to make it possible to carry out continuous lactobacillus growth and acid production with a growth/fermentation tank and to eliminate the necessity for one or more other tanks for growth, storage or metering. It is likewise intended to carry out the metering using a simple method and a simple device. Lactobacilli are grown in wort in a tank. In a number of layers depending on the number of additions of amounts of wort, this layer migrates to the point of exit from the growth/fermentation tank and, during this process, undergoes further fermentation with acid production. Production of lactobacilli and lactic acid for addition to the beer production process.

Patent DE-4334961-A1 (DE)
Inventor: STRASSNER HANS M
IPC: H04R3/00
Filed: 1993-10-13
Abstract: A device for transmitting signals from an amplifer (8) to a loudspeaker (9) consists of a cable (1) having a number of forward and return conductors (2, 2') electrically connected to one another at their ends and a sound modification element (14) which exhibits a series inductance (L1, L2) and a series resistor (R1, R2). Using the sound modification element (14), the cable (1) can be optimally adapted to the given loudspeaker/amplifier combination (8, 9). The signal transmission device also exhibits an attenuator (13) at the cable end at the load. The attenuator (13) suppresses the tendency to oscillation of the amplifer which can occur in the case of cables having a high capacitance. In particular, long cable lengths which lead to a particularly high capacitance, thus do not present any problems in the signal transmission device according to the invention. <IMAGE>
