Patent DE-3742654-A1 (DE)
Title: Method for tuning an RF modulator
Inventor: SCHUELEIN REINHARD
IPC: H03J1/00
Filed: 1987-12-16
Abstract: The novel method is to ensure fast and precise modulator tuning. Furthermore, the most advantageous free channel is always to be automatically selected for the modulator tuning. In the novel method, channel allocation of the receivable transmitters which is available at the respective receiving location is determined via an automatically calibratable tuner. In addition, a permanently stored tuning range of the modulator is interrogated channel by channel in order to determine the free channels which can still be considered for the channel selection. Of the channels to be considered, the one which has the greatest channel spacings with respect to the occupied channels is selected. One application of the novel method is of advantage, in particular, in video recorders having automatically calibratable tuners.
Patent DE-3805671-A1 (DE)
Title: Work glove for burring mouldings
Inventor: PELZER HELMUT
IPC: A41D19/015
Filed: 1988-02-24
Abstract: In the production of pressed blanks of fibre mats, it is impossible to prevent the edges of the items themselves and of the openings provided in them having an interfering burr formation which has to be removed. This is usually removed by means of a grinding block, files or the like, which has proved to be time-consuming and to harbour the risk of accidents. By means of the work glove according to the invention, the time required for burring is to be reduced and the risk of injury is to be eliminated. The work glove consists of two parts, the inner glove being made of a textile fabric, leather or synthetic leather. The outer glove is formed from a knitted steel wire. Usable wire thicknesses range, for example, from about 0.2 mm to 0.8 mm. The mesh width is essentially adapted to the wire thickness and can range from about 1 mm to about 4 mm. The use of the new glove leads to a considerable reduction in the time required and to the elimination of the risks of injury.

Abstract: The selective determination of  alpha -ketoisocaproate in body fluid samples, in particular in serum, is achieved without previous separation directly in the fluid from which, where appropriate, protein has been removed, by use of KIC-specific D- alpha -hydroxyisocaproate dehydrogenase, which derives specifically from strains of Lactobacillus casei producing this enzyme, in particular Lactobacillus casei ssp. pseudoplantarum or casei, in the presence of NADH. KIC determination is used, in particular, for diagnosing maple syrup disease. Expedient for this purpose are analytical kits which have a divisible stock of D- alpha -hydroxyisocaproate dehydrogenase from Lactobacillus casei, in particular from the Lactobacillus casei (DSM 20008). <IMAGE>
Patent DE-3908914-A1 (DE)
Inventor: LEINBERGER KLAUS
IPC: B01F5/04
Filed: 1989-03-18
Abstract: The admixing of a gas to a gas flowing through a line (1), for example the admixing of oxygen for enrichment of the blast in shaft furnaces, is usually effected by means of an angled pipe (2) which is taken into the line and whose endpiece (8) is closed and runs in the direction of the line. The endpiece has nozzle orifices (7) which are distributed over its length and from which the gas to be admixed is blown perpendicularly into the flowing gas. For optimised mixing, a defined exit velocity of the gas to be admixed is necessary. To ensure this exit velocity even if the pressure of the gas to be admixed is changed, a spring-loaded piston (9) subjected to the gas to be admixed is provided in the endpiece. Depending on the pressure of the gas to be admixed, the piston then clears a greater or lesser number of the nozzle orifices distributed over the length of the endpiece. <IMAGE>

Title: Control device for inlet and exhaust valves of an internal combustion engine with at least one deactivatable cam on a camshaft
Inventor: NEUMANN JOACHIM ING GRAD
IPC: F01L13/00
Filed: 1989-06-27
Abstract: Deactivatable cams (5, 6, 7) on a camshaft (1) are arranged axially displaceable on the said camshaft. By increasing the pressure of a pressure medium in a pressure chamber (27, 28, 29) adjacent to them, the cams (5, 6, 7) are axially displaced for the purpose of engaging claw couplings (14, 15, 16) for each individual cam, which couplings make a torsionally fixed connection between the cams (5, 6, 7) and the camshaft (1). So that disengagement of the claw couplings (14, 15, 16) for the purpose of deactivating the cams (5, 6, 7) reliably occurs only when the valves (39) are in the closed position, individual flanks (42) of claws (17) of the claw couplings (14, 15, 16) are inclined (angle  alpha ) in relation to the associated surface lines so that the claws (17) narrow from the base of the claw towards the tip of the claw, in such a way that, during the closing movement of the valves (39), torques exerted by their closing springs (40) on the cams (5, 6, 7) are partially converted into axial forces for disengagement of the claw couplings (14, 15, 16) when the pressure of the pressure medium is reduced (Fig. 1). <IMAGE>
