Title: Oven with a cooking chamber which can be closed by an oven door, for cooking food
Inventor: GERL JOSEF
IPC: F24C15/00
Filed: 1987-12-14
Abstract: In ovens of this type, e.g. microwave ovens, the problem exists that during the cooking treatment, owing to the moisture issuing from the product being cooked, the steam is deposited on the interior of the glass pane of an inspection window in the oven door and prevents inspection. In order to counteract such a "misting up" of the inspection window, according to the invention inner ventilation openings are provided on the periphery of the inspection opening, which ventilation openings are turned towards the inner face of the glass pane and are connected to an air-conducting channel and an air source. <IMAGE>

Patent DE-3811952-A1 (DE)
Inventor: STOY ERICH
IPC: B21B13/14
Filed: 1988-04-11
Abstract: In the hydrostatic support of the rolls of a rolling mill, the utilisation of the supporting surface available is of particular importance both for centring and for expenditure in terms of energy and costs. However, the hitherto known supporting devices for rolls permit only a relatively low utilisation of the supporting surface available and are therefore afflicted by a correspondingly high expenditure in terms of energy and costs. According to the invention, very high, almost 100% utilisation of the supporting surface of the supporting element is achieved by the fact that each roll (2) is provided with only one supporting element (1), which extends over the entire length of the roll (2) and the shell-shaped recess (3) of which is preferably of elliptical cross-section and that, arranged in the shell-shaped recess of the supporting element (1), are mutually spaced blocking webs (5) which extend transversely to the said element and divide the shell-shaped recess (3) into a plurality of pressure chambers (6) to which the pressure-medium lines (7) are connected.

Title: Cutting board
Inventor: MUELLER HERMANN-JOSEF
IPC: A47J47/00
Filed: 1988-04-16
Abstract: Known cutting boards consist of end-grained wood blocks of rectangular cross-section which are glued to one another at their long sides. In the case of these known cutting boards, the glueing becomes detached owing to the high moisture absorption of the end-grained wood blocks, with the result that the cutting board becomes unusable. It is proposed to join the long sides of adjacent end-grained wood blocks to one another by means of dovetails glued to one another.

Title: Lubricating oil pump
Inventor: OTTO DIETER DIPL ING
IPC: F04C14/24
Filed: 1988-07-19
Abstract: Known lubricating oil pumps in motor vehicles are designed to take the form of gear pumps in such a way that their function is limited to generating a pressurised stream of lubricating oil. This makes it necessary to integrate the functional elements for further functions, especially for gradually reducing the superatmospheric pressure and providing additional oil for special requirements, in the motor as additional assemblies. The innovative lubricating oil pump has a valve arrangement for the outflow and an inlet control system and outlet control system. The pump case is enclosed by a polygon on which the channels and the control devices are arranged. The individual functional elements, in particular the inlet valve device (39), the outlet valves (54), the load indicating channel (44) and the filter are distributed across the sides of the polygon. <IMAGE>

Title: Process for recovering pure methane from natural gas
Inventor: STOCKMANN RUDOLF DIPL CHEM
IPC: C07C7/04
Filed: 1988-08-31
Abstract: The recovery of pure methane from natural gas by separating off higher- and lower-boiling components in a plurality of separation columns takes place as follows: liquefied natural gas is compressed to the working pressure of a first separation column and partially evaporated in indirect heat exchange with process streams which are to be cooled down. Preferably, the partial evaporation takes place in the top condensers of the separation columns against the rising top fractions. In this way, the cold contained in the liquefied natural gas is utilised for the recovery of pure methane. After the higher-boiling components have been separated off in the first separation column, the components' top product consisting of methane and lower-boiling components is partially liquefied, and the lower-boiling components are separated off in a further separation column. The partial liquefaction of the top product preferably takes place against liquid pure methane product.

Title: Position sensing system
Inventor: TAAKE MANFRED
IPC: H03M1/30
Filed: 1988-09-01
Abstract: In a position sensing system having three equidistant markings for tracks (5, 6, 7) carrying different incremental dimensions on two track carriers (1, 3), at least one (7) of which tracks extends along the path along which the positions to be determined are located, the incremental dimension of the third track (7) is smaller or larger by a predetermined number of increments of the first track (5) than the incremental dimension of the second track (6) which is a predetermined multiple of the incremental dimension of the first track (5). The two track carriers (1, 3) can be moved free of slippage relative to one another and are coupled to one another via a motion transmission device. The absolute positions are determined via signal processing electronics on the basis of the number of increments of the first track (5) by which the markers (R, T), which in each case follow one another during a position scanning along the path, of the second and third tracks (6, 7) are offset with respect to one another. <IMAGE>

Filed: 1988-09-29
Abstract: To improve the separating efficiency of a cyclone-type stuff cleaner, the rotationally symmetrical inner wall (3) of the separating chamber (1) is provided with dead spaces (4) relative to the throughflow. These dead spaces extend essentially lengthwise and in one embodiment are parallel to the generatrix of the inner wall (3), on which they are arranged at regular intervals. The dead spaces (4) are advantageously shaped like grooves. The cavities of the grooves (4) are not flushed during operation by the throughflow of the aqueous suspension of stuff; the solid particles to be remove are carried to the inner wall (3) by the centrifugal forces and collect in said cavities, which direct the solid particles downstream through the grooves (4). Preferably, the grooves (4) are formed between rods which form ridges (5) that delimit the grooves (4).
Patent DE-3836208-A1 (DE)
Inventor: JOHANSSON HENRIK
IPC: G01F11/28
Filed: 1988-10-24
Abstract: The dosing of a flowable substance is effected in a system of branched pipes, wherein an inlet branch (1) leads to a juncture (2) which connects to two or more extension branches (3,4). The substance to be dosed is allowed to flow past the juncture into one of the extensions (3), where the flow is stopped. The fraction of substance which has entered the extension branch is separated from the fraction remaining in the inlet branch by letting an auxiliary substance immiscible with the substance to be dosed flow in through one of said branches (3) and a second extension branch (4) in such manner that one of the fractions (15) is carried away by the flow of the auxiliary substance. The two fractions are separated by a boundary surface created by surface tension at the juncture of the pipe branches. The precision of dosage achieved by the fact that a boundary surface can be repeatedly produced at the same place. The invention is suited for wet chemical analyses in which the substance to be dosed is a fluid, generally a water solution, and the auxiliary substance may be a gas e.g. air, or another fluid immiscible with water. <IMAGE>
Patent DE-3841938-A1 (DE)
Inventor: DOEHLER PETER
IPC: H03K7/10
Filed: 1988-12-13
Abstract: The invention relates to a method to control externally excited DC motors. In this process, voltage pulses of constant pulse duration are applied to the armature. The pulse repetition frequency varies as a function of a comparison between the armature e.m.f. during the pulse intervals and a selectable reference voltage value. In order to achieve a low noise development and quiet running even during starting of the motor, it being the case that low power losses are to occur and that there is no need to adapt the circuit to different motor types and motor powers, a method is proposed in which the temporal distance between the voltage pulses is measured and the voltage pulses are subdivided in each case into sequences of voltage subpulses. In this process, the pulse-interval ratio is dependent upon the measurement result of the said temporal distance. Consequently, the pulse-interval ratio of the voltage subpulses is reduced given a large temporal distance between the voltage pulses, and increased given a small temporal distance.
