Title: Electronic balance with analog and digital display
Inventor: OLDENDORF CHRISTIAN
IPC: G01G23/37
Filed: 1988-02-25
Abstract: For an electronic balance with a digital display for the accurate display of the weighing result, with an analog display for rough display of the balance loading, the analog display consisting of a horizontal band of dots (7) which can be activated, and with a taring possibility, it is proposed to arrange, directly above or directly below the horizontal band of dots (7) which can be activated, further segments (8, 10) which can be activated and with which, at a large number of points along the horizontal band, a "T" symbol (9) can be activated, and, on taring, to activate the "T" symbol at the point which corresponds to the tare weight on the horizontal band (7) of the analog display. By these means, the point at which taring has been carried out can be displayed in a simple manner. The further segments (8, 10') can advantageously also be used for scaling the analog display. <IMAGE>

Patent DE-3817523-A1 (DE)
Title: Hi-hat drive
Inventor: BAERSCH HERMANN
IPC: G10D13/06
Filed: 1988-05-24
Abstract: In contrast to that of a conventional hi-hat, the drive consists of the pedal (1) known from OS DE 3731992 A1 or of a one-part pedal which is of approximately 120@-wedge-shaped design. In addition to the conventional fastening (2), the pedal is connected to the foot pedal mounting (5) by a band (4), belt or a chain, running via pinions, which runs via a roller (3). By pressing down the front pedal part, the conventional operation is ensured. If, however, the rear part is depressed, the cymbals, which have in the meantime opened, are, dependent upon the fastening (2), closed again, which, measured in relation to the treading operation, produces a double beat, dependent upon the interaction of the fastenings (2 and 4). <IMAGE>

Title: Container with a sealable insertion lid
Inventor: GERSTER FRANZ
IPC: B65D43/16
Filed: 1988-07-22
Abstract: An insertion lid (11), which is divided into two sections (19 and 21) by an impression line (17), is sealed on the container (9). The lid/container connection differs in the sections (19, 21).

Title: Program support for an electrical time switch
Inventor: STRACKE GUENTER
IPC: G04C23/08
Filed: 1988-07-26
Abstract: In the case of a multi-piece annular program support for an electrical time switch, having a drive for touch-sensing its circumference in order to change the operating mode (for example ON) of a switch into another mode (for example OFF) and having switching elements which are guided in a captive manner, parallel to the axis and/or such that they can be displaced radially, between latching means and stops, according to the invention, the switching elements a) are combined from a flat-edge piece (in the form of a rod) and a cantilever arm (which is possibly shorter and is integrally formed parallel thereto) to form a U-shaped part, b) are combined (grouped and arranged to match the number of timing stages) to form a ring in one of the two integral ring bodies in two different variants, specifically on the one hand guided in the axial direction and on the other hand being displaceable radially, and c) are mounted exclusively by the connection of the profile support to an adaptor being held and secured against falling out by fastening elements having snap-action tabs. In a further refinement, the switching elements are constructed alternately symmetrically and two such symmetrical pieces are in each case accommodated in a groove.

Patent DE-3837771-A1 (DE)
Title: Engine and machine
Inventor: MUELLER LOTHAR DIPL ING
IPC: F02F7/00
Filed: 1988-11-07
Abstract: The engine or machine, in which at least one force acts by way of a connecting rod (9) on the throws (2) of a crankshaft drive (8), thereby causing the latter to perform a rotational movement, is characterised in that the said force is generated by a controllably pre-loaded mechanical or pneumatic spring (12, 13), which during its working travel from 0@ to 180@ crank angle relaxes and in so doing, due to the geometric path of the points of action of the connecting rod (9) on the throws (2) of the crankshaft drive (8), acts on a larger lever arm than during the compression travel from 180@ to 360@ crank angle, with the result that a greater cumulative torque is delivered during the working travel than is needed for recompression of the spring (12, 13) during the compression travel (Fig. 1). <IMAGE>
Patent DE-3839438-A1 (DE)
Inventor: KAYS RUEDIGER DR ING
IPC: H04N9/31
Filed: 1988-11-23
Abstract: For the large-screen projection of colour television pictures, picture reproducing arrangements comprising three separate picture tubes are in most cases used which are followed by projection optics. The colour television picture is created on a projection screen by superimposing the three monochrome television pictures. Instead of picture tubes, light valves can also be used, particularly liquid- crystal light valves with illumination optics. To increase the luminance resolution of a light valve projector, a geometric offset arrangement, preferably by half a picture element width in the horizontal and vertical picture direction of the light valves is provided. New picture scanning values are calculated by a signal processing circuit arranged in the light valve projector, in such a manner that the position of the picture scanning values and the position of the picture elements of the picture scanning values and the position of the picture elements of the light valves correspond to one another. The light valve projector is particularly suitable for reproducing high-resolution colour television pictures. <IMAGE>

Title: Method and heating furnace for heating billets, ingots, slabs, sheets and similar products to be heated
Inventor: PATALON HEINRICH DIPL ING
IPC: F27D99/00
Filed: 1988-12-21
Abstract: In order to obtain an improved and more flexible method and a heating furnace suitable for carrying out this method, it is proposed that, in a heating furnace whose furnace chamber is constructed for the deposition and stepwise transportation of the products to be heated with a hearth or beam system and a lifting system, the said products to be heated, which in the rest phases during the heating-up are mounted on the hearth or beam system, are moved down by a hearth bogie for transportation, received by the receiving stands of this hearth bogie by a vertical relative movement caused by means of the lifting system and are lifted off from the hearth or beam system, after which the hearth bogie transports said products to be heated by one conveying step and thereafter deposits them on the next free portion of the hearth or beam system by renewed vertical relative movement. For this purpose, the walking-beam system can lift or lower the hearth bogie or hearth bogies with respect to the fixed hearth or beam system of the furnace chamber, or the latter is vertically movable with respect to the hearth bogie or hearth bogies. Also, the receiving stands of the hearth bogie can be liftable and lowerable by means of individually controllable working cylinders arranged on the hearth bogie.

Title: Device for dust sealing
Inventor: AXT WERNER DIPL ING
IPC: B65G69/18
Filed: 1989-03-22
Abstract: In a device for dust sealing between a stationary and a swinging (oscillating) component on swinging (oscillating) conveyors or swinging (oscillating) screens, the transmission of dynamic forces from the swinging to the stationary component is to be minimised, and at the same time rapid and simple mounting and demounting is to be ensured. This is achieved in that the profiled foam-plastic body (3, 3', 3'') lies, at least in a central section between the two holding elements, outside a plane joining these two holding elements. <IMAGE>

Patent DE-3911380-A1 (DE)
Inventor: AOYAMA YOSHITAKA
IPC: B23K9/20
Filed: 1989-04-07
Abstract: The apparatus comprises a telescopic feed rod (20) including outer and inner shafts (23, 24), a magnet (22) being fixed to the end of one of the two shafts.

Patent DE-3917405-A1 (DE)
Title: Hydraulic multiple disc clutch
Inventor: GARTNER HELFRIED
IPC: F16D25/0638
Filed: 1989-05-29
Abstract: In a hydraulic clutch system the cylinder (3) clamps the plates (4) when supplied with fluid under pressure into the cylinder bore (8). A restriction orifice (9) limits the amount of fluid flowing into the enlarged area (10) and the distortion of the plate (4a) closes off the opening (3a) and radial groove (11), the clutch is thus engaged. When the pressure is released the plates (4)(4a) recover their initial position allowing a rapid fall in pressure and flow through orifice and groove.
