Title: Sales counter
Inventor: LEUPRECHT KARL
IPC: A47F3/04
Filed: 1983-04-12
Abstract: The invention relates to a cleaning device for the inner space and in particular the evaporator of a sales counter, specifically a chill counter. In the case of hitherto customary, firmly installed, cleaning devices there is the problem that they do not permit fully automatic and hygienically satisfactory cleaning of the sales counter. The invention solves this problem by providing a spray device (1) which consists of a nozzle arrangement (4), with few individual nozzles, and of a drive (30). The nozzle arrangement (4) is connected via an elastic tube (7) to a supply device (18) and is driven in a reciprocating or revolving manner by the drive (30). The mobility of the nozzle arrangement (4) enables the spray jets to be clustered closer together and to be directed at high pressure onto the surfaces to be cleaned and in particular onto the lamellae of an evaporator. The nozzle arrangement (4) can be designed as a nozzle rake with individual nozzles directed at an angle to one another, as a result of which the spray jets strike the surfaces to be cleaned from different directions and achieve an especially good cleaning effect. According to the invention, the supply device (18) is designed as a high-pressure supply device for feeding different cleaning agents in a cleaning programme. <IMAGE>

Patent DE-3325628-A1 (DE)
Title: Method and arrangement for protecting crop plants against the action of incompatible temperatures
Inventor: KUECKENS ALEXANDER
IPC: A01G9/18
Filed: 1983-07-15
Abstract: To protect crops in greenhouses, in which the crops are grown in bed-like or table-like areas which are insulated, thermally and for purposes of gas exchange, relative to the interior atmosphere of the greenhouse, it is proposed that the covering of these crop beds be so designed that one shelf of the double-shelved covering bears, or is connected to, a reflective layer which reflects as much as 10 to 90% of the incident light, especially in the infrared region, or converts it into heat in order to keep these fractions of the light away from the crop plants. It is particularly effective, and versatile in application, to provide the combination within the double-shelved covering of a reflective layer, for example of gold, and a layer of phototropic material which automatically modifies the transparency as a function of the nature and intensity of the incident light radiation. The reflective measures are significantly assisted if a CO2-enriched spray mist is used to trigger absorption of IR radiation for protective cooling or heating purposes. If the reflective zones are interrupted by non-reflective zones, greater reflection, as much as 90%, can be provided in the reflective zones.

Title: Two-piece sheet-metal core with centre-limb fixing
Inventor: WAASNER BRUNO
IPC: H01F27/245
Filed: 1983-07-28
Abstract: The invention relates to a sheet-metal core which is composed of two core parts (1, 6) and is formed from layers of sheet-metal blanks of equal size, forms two yokes, three limbs (3, 2, 4) and two windows on which both outer limb-yoke regions are firmly held together (7), has a separating joint (8) between the free end of the centre limb (2) and the other core part, and fixes the centre limb (2), which is formed by the one core part, with respect to the other core part. In this case, it is desirable that the free end of the centre limb be fixed with respect to the other core part just by means of the sheet-metal blanks which are of equal size. This is achieved in that at least one of the sheet-metal blanks (9) which are of equal size is displaced with respect to the others in the direction of the centre limb (2) and forms an overlap at the junction of the centre limb (2) with the other sheet-metal part (1). Humming of the sheet-metal core and of the transformer produced from it is considerably reduced. <IMAGE>

Title: Heat recovery from the heat of exhaust gases
Inventor: UNTERLAENDER JUERGEN DIPL ING
IPC: F28D21/00
Filed: 1985-01-15
Abstract: The devices make use of the heat of exhaust gases from heating installations and individual furnaces by extracting heat through cooling the fuel gases. The device can be used for increased utilisation of the individual furnace in such a way that the device, which is inserted between the furnace and stack, additionally extracts radiative and convective heat which it introduces into the room. This operation is possible in an analogous way directly from the extraction of the flue gases from the stack. In addition, the convective heat obtained can be used as additional warm air heating. The power consumption of the two ventilators is approximately 40 watts/hour, which is approximately 1 KW/24 hours = 0.14 DM/day. That is to say operating costs which bear no relation to the thermal energy additionally obtained. Possible applications: For the purpose of greater utilisation of heat in connection with individual furnaces, use as additional warm air heating from the heat of exhaust gases from individual furnaces or heating installations. <IMAGE>

Title: Device for applying a protective layer to the welded or soldered seam of can bodies
Inventor: FREI MATTHIAS
IPC: B05C7/06
Filed: 1985-04-16
Abstract: Device for applying a protective layer to the welded or soldered seam of can bodies, having an application roller for the application of a coating compound to the inner side (15) of the can body within an area covering the seam, which roller has at least one recess (10) in a central area (9) of its central part (6) with an area width of less than 60% of the width of the central part (6) and the peripheral surface line (5) of which has at least one salient point and/or at least two inflexions in this central area (9). The invention makes it possible for the first time to achieve optimum layer thicknesses of the coating across the welded or soldered seam which are neither too little for the stresses which arise in the long-term storage of aggressive liquid nor too great for the tearing stress on the coating which occurs when the edges of the can body are beaded. Due to the design of the application roller, an optimum profile of the applied coating layer with the maximum layer thickness directly above the welded or soldered seam is obtained, something which was impossible to achieve with the hitherto known application rollers. <IMAGE>

Patent DE-3517626-A1 (DE)
Title: Circuit arrangement for rotation speed control of an electric motor
Inventor: CHAUMONTET BRUNO
IPC: H02P7/295
Filed: 1985-05-15
Abstract: The circuit arrangement for rotation speed control of an electric motor by phase control has a microcomputer (Z) whose program memory (MP) contains a command sequence of commands which are organized in loops of predetermined duration. This command sequence comprises commands for calculating a desired rotation speed setting as a function of a code which is received from a selection device (SEL) and corresponds to a desired operating mode, for measuring the actual rotation speed of the motor (M) on the basis of the pulses which are produced by a rotation speed transmitter (CT), for comparison of the rotation speed setting with the actual rotation speed, and for calculating the switching-on delay time of an interface (6) which controls the transmission of the electrical power to the motor (M). Specific commands of the same program loops are set up for the purpose of at the same time initializing the delay as soon as the mains-synchronizing signal is received, implementing the delay which corresponds to the previously calculated switching-on delay time, and switching-on the said interface (6) at the point in time at which the delay time has elapsed. The invention is intended primarily for domestic electrical apparatuses. <IMAGE>
