Title: Cooling process for pasteurising chambers
Inventor: BREUNING ERNST DR ING
IPC: A23L3/10
Filed: 1981-02-26
Abstract: The invention relates to a cooling process in pasteurising chambers - represented greatly simplified in a vertical section - in which products (9) are heated in batches during a first time interval by means of the already heated water from a preheating and cooling storage vessel (17), are heated up and pasteurised during a second time interval by means of water from the heating-up storage vessel (14), and cooled during a third time interval by means of water from the preheating and cooling storage vessel (17). The heat extracted in the process from the product (9) and fed to the water is fed after changing the batch to the newly introduced batch during its first time interval. In many cases, it is necessary during the cooling process for a proportion of the product heat to be discharged outwards using fresh water. According to the invention, during a part of the cooling time the water is kept at a constant temperature under the control of a clock by the flow of fresh water by means of the temperature sensor (23) and solenoid valve (22) and simultaneously kept at constant volume by the outflow controlled by means of the water-level controller (18) and solenoid valve (19). The process and this device replace a very expensive and complicated equipping of the chamber otherwise required. <IMAGE>

Title: Device for displaying the time using the position of the sun
Inventor: HYMER ERWIN
IPC: G04B47/06
Filed: 1981-06-02
Abstract: The subject-matter of the invention is a device for displaying the time using the position of the sun. So-called sun-dials have previously been known which are mounted on the external facades of buildings and display the time using the position of the sun with a relatively high degree of accuracy. The object of the invention is to widen the application and distribution of such devices to a substantial extent. In order to achieve the set object, the invention is characterised in that the device is transportable. According to the invention, it is proposed to miniaturise a sun-dial in such a way that it can be carried in the pocket of the user, permitting the latter to tell the time using the position of the sun without too much trouble. A precondition for this is precise alignment of the device in accordance with the position of the sun, which can be carried out in different ways. An important characteristic is furthermore that a compass is also designed to be used as a sun-dial. This makes it possible to extend considerably the applicability of a conventional compass, by making it possible to tell the time as well as determine the geographical position.

Patent DE-3125938-A1 (DE)
Title: Cladding panel
IPC: E04F13/08
Filed: 1981-07-01
Abstract: The invention proposes a cladding panel which comprises reinforcing fabric consisting of alkali-resistant filaments, facing bricks designed in a clinker-like or natural-stone-like manner being arranged on the reinforcing fabric on the upper side, i.e. the visible side, such that they leave gap-like spaces between them. The novel cladding panel is preferably processed such that there is applied, onto the load-bearing substructure, a bonding-mortar layer into which the mat, formed by the reinforcing fabric and the facing bricks, is pressed before said layer has set, with the result that the bonding-mortar layer penetrates through the joint-like spaces, the bonding-mortar layer present in the joint-like spaces then being finished by jointing.

Title: Clamping device for the clamping jaws of a sheet-metal stretcher
Inventor: KUTZ HEINRICH
IPC: B21D25/04
Filed: 1982-02-10
Abstract: A clamping device for the clamping jaws (5, 6) of a sheet-metal stretcher has, for each pair of clamping jaws, a push rod (15) which slides in guides (14) in the clamping head (1) in the stretching plane and on which are pivoted two articulated rods which, in turn, are connected in articulated fashion to the clamping jaws (5, 6) and move these clamping jaws synchronously in two guides (3, 4) arranged in a wedge shape relative to one another, backwards to effect closure and forwards to effect opening. Because of the risk to the articulated rods and the clamping device in the event of a tear in the sheet during the stretching operation or the differential straining of the sheet (13) by the upper and lower clamping jaws (5, 6) due to the occurrence of very large and different forces on the two articulated rods, the articulated rods are connected to the clamping jaws (5, 6) in a manner which allows them to be decoupled. In this arrangement, the articulated rods are pivoted as bell-crank levers (23, 24) on the hydraulically movable push rod (15), with a fulcrum (22). The short arm is pivotably mounted via hydraulic pivoting cylinders (20, 21) arranged on the push rod (15), and the long arm can be coupled to drive stubs (31, 32) of the clamping jaws (5, 6) via mouth-shaped openings (29, 30) and decoupled from the clamping jaws by pivoting. <IMAGE>
Patent DE-3204723-A1 (DE)
Title: Friction smoke generator
Inventor: REICH WOLFGANG
IPC: B29C70/02
Filed: 1982-02-11
Abstract: A friction smoke generator is indicated, which can be used in association with smoking chambers of any design and in which a squared timber, which is used for smoke generation and is guided displaceably in a vertical guide device, can be pressed with defined minimum force against the friction wheel which is driven by an electric drive motor. For this purpose, there is provided an anchor member which engages on the squared timber, can be driven by a drive device, presses the squared timber against the friction wheel and is alternatively designed as a profiled piece which is supported on the end of the squared timber at a distance from the friction wheel or as a gripper which engages on the end of the squared timber close to the friction wheel. For appropriate driving of the anchor member,cable pull, chains, spindle drives and, in the case of the anchor member being designed as a gripper, dual-action pneumatic working cylinders are provided. By means of a control device which responds to the speed of the friction-wheel drive motor, the force, with which the squared timber is pressed against the friction wheel, can be kept in a favourably low variation range. The course of smoke generation phases and pauses is controlled in such a manner that, after starting of the friction wheel, the pressing of the squared timber on the latter is first triggered with a time delay and, before the friction wheel drive is switched off, the friction wheel is relieved, e.g. by lifting the squared timber, as a result of which a low-noise and gentle operation of the friction smoke generator is achieved.

Title: Piston valve carburettor
Inventor: SEHRNDT CHRISTIAN DIPL ING
IPC: F02M7/17
Filed: 1982-03-29
Abstract: Piston valve carburettor, especially of the throttle or constant pressure type, in which a valve slide, which carries a nozzle needle necessary for dosing of the fuel, is arranged so that it can move vertically and the nozzle needle projects into a needle jet section. By a precise allocation of a quantity of fuel to a quantity of air required by the internal combustion engine, the invention serves the object of reducing the quantity of fuel required by the internal combustion engine and reducing the pollutants emitted. The nozzle needle serving for dosing of the fuel is arranged in a holding plate, which according to the invention directly forms the lower, air-dosing surface of the piston valve and thereby the upper connection of the venturi section (2). At the same time the holding plate is preferably fixed by a needle spring over the nozzle needle, the design of the lower wall of the piston valve permitting a free movement of the nozzle needle in the event of a position change, so that this is possible without removing nozzle needle and holding plate from the piston valve. <IMAGE>

Title: Hide washing machine
Inventor: EDWARDS ROBERT EUGENE
IPC: D06F9/00
Filed: 1982-04-06
Abstract: A hide washing machine is described, having a conveyor belt (35) which carries a hide from a loading station (36) to a washing station and through the latter, in which support elements (38, 45, 46) for the conveyor belt (35) are provided. A number of driven brush rollers (60, 61), which are so arranged that they curve the conveyor belt (35) between the support elements (38, 45, 46) effect a partial engagement of the hide (S) carried by the conveyor belt (35) around the brush rollers (60, 61), so that a good cleaning action is achieved by the brush rollers. The hide washing machine comprises a reversible drive (80) for a first of the brush rollers (60), as a result of which this first brush roller rotates in a hide conveying direction, when a hide is being conveyed into the washing station, and thereafter a rotation in a direction opposite to the hide conveying direction is effected, so that a braking or slowing force is exerted on the dragged part of the hide. <IMAGE>
Patent DE-3221016-A1 (DE)
Title: Drive device
Inventor: JAEGER ODIN
IPC: E06B9/32
Filed: 1982-06-04
Abstract: A drive device serves for opening and closing trapezoid blinds or double roller shutters. In the case of trapezoid blinds, pull elements for the blind slats are on opening first actuated simultaneously, until the blind underside is situated at a window height where an upper inclined limit begins and, subsequently, only actuation of the pull element extending over the entire window height takes place for further opening of the blind. For these successive drive movements, the drive device according to the invention has a transmission with two outputs, one output, for the pull element extending over the entire window height, being permanently connected to a transmission shaft, while the other output has a coupling for coupling in and uncoupling this output. The coupling in and uncoupling takes place via an axial displacement movement of the transmission shaft which to this end is designed in regions as a threaded spindle. For double roller shutters, couplings are provided in the drive device in each case between the transmission shaft and the outputs, which couplings can alternatively be brought into engagement for in each case a closing or opening movement of one of the two roller shutters. As a result, it is possible to achieve with a single drive movement, e.g. by means of a crank handle or the like, successive drive movements, by means of which a front roller shutter can first be lowered, before the rear roller shutter is actuated or, conversely, the rear roller shutter can first be raised with the front roller shutter closed, before the front roller shutter is subsequently opened.
