Title: Heating device for a motor vehicle which can be driven by electricity
Inventor: WULF HELMUT
IPC: B60H1/00
Filed: 1982-12-10
Abstract: In a motor vehicle, in particular a bus, which can be driven by electricity, having a heat exchanger which serves to heat the vehicle and can be heated up electrically, in order to improve the availability and the operating range while allowing for operation which is as environmentally friendly as possible, it is proposed in the case of the vehicle constructed as a dual power bus to operate the auxiliary fuel heater only in a non-electrified section and to arrange this heater in series with the electrically heatable heat exchanger constructed as a flow heater. The two heating devices are assigned a common electrical water pump. If the bus is operated electrically, in order to avoid the internal combustion engine cooling down, the cooling water is heated up by the flow heater even when the vehicle heater is switched off whenever the cooling water reaches a predetermined lower threshold value.

Title: Device for automatic and autoregulated watering
Inventor: PERNIGOTTI ALBINO
IPC: A01G27/00
Filed: 1983-02-02
Abstract: The present invention relates to a device for water supply in order to water pot plants, in which this supply takes place for a time span, which can be defined previously as required, by the movement of a rocking lever, on one arm of which there is a fixed counterweight and on the other arm of which there is a variable counterweight which consists of a regulating pot which fills with water while the supply to the flowerpots takes place. When the water in the pot reaches a given level, the increased weight in the pot moves the rocking lever in such a manner that it makes possible the closure of the water supply valve and consequently the shutting off of the supply. The following supply will take place when a sufficient quantity of water has evaporated in the regulating pot so that the lighter pot rotates the rocking lever in its point of rotation and again brings the water supply valve into the open position. With this system, the water supply takes place only when a certain degree of water evaporation is achieved in the regulating pot and accordingly also in the flowerpots. <IMAGE>

Title: Apparatus, in particular for high-pressure cleaning devices
Inventor: OESTERGAARD TAGE VYFF
IPC: B01F5/04
Filed: 1983-03-04
Abstract: The invention relates to an apparatus, in particular for high-pressure cleaning devices, for adding a cleaning agent to the stream of water used during this process. The apparatus according to the invention uses a solid body of cleaning agent and achieves a constant metering of the amount added without using any devices associated with a pressure drop, by virtue of the fact that the surface of the solid cleaning agent which is exposed to the stream of fluid remains constant whilst said agent progressively dissolves. Moreover, by means of a valve which can be actuated manually or automatically it is possible at any time to add the cleaning agent both during low-pressure operation and during high-pressure operation.

Title: Pressing device for material in strip form, in particular for dewatering a web of paper
Inventor: STEINER KARL DR
IPC: D21F3/02
Filed: 1983-05-13
Abstract: In a pressing device for material in strip form, an elastically deformable, tubular jacket runs around a fixed supporting body, designed as a hollow support. The jacket can be pressed with the aid of a pressing shoe, which has a concavely shaped pressure-applying surface, against a back-up roll in such a way that there is a pressing zone extending the running direction of the jacket. The pressing force exerted in the pressing zone on the web of paper running through is generally less at the beginning of the pressing zone than at its end. In order to be able to influence the progression of the pressing-force curve during operation, the pressing shoe can be adjusted in the circumferential direction in relation to the back-up roll.
Patent DE-3318881-A1 (DE)
Title: Cover for lawn mowers and other gardening implements
Inventor: COEPPICUS ROLF
IPC: E04H6/00
Filed: 1983-05-25
Abstract: In order to prevent corrosion (rust), which inevitably occurs when a lawn mower or other gardening implements are left in the open air, affecting the metal parts of the lawn mower, the lawn mower is placed on a corrosion-proof base. This base has a seal running around it. A corrosion-proof hood is fitted into this seal of the base, which hood is positioned over the lawn mower. If the air between the base and the hood is then pumped out by means of a (vacuum) air pump via a valve, an air-void results between said base and hood. Since corrosion (rust) only occurs under the action of water (moisture) on metal, but it is no longer possible for there to be any water (vapour) in the vacuum, the lawn mower does not corrode in said vacuum. The point at which the vacuum is reached and continues can be read off from a manometer. In order to prevent theft, the base is either anchored firmly in the ground or tied or chained to a post, tree or the like. If relatively large (steel) plates are used instead of the hood, they produce an accessible garden shed in which all conventional gardening implements can be left so as not to rust.

Title: Circuit for regulating the temperature of a working fluid
Inventor: RACH LADISLAV DIPL ING
IPC: F15B21/042
Filed: 1984-01-27
Abstract: The circuit for regulating the temperature of a working fluid relates to machines which use a hydrostatic drive. A thermostat is fitted into the system for regulating the temperature of the working fluid. The thermostat automatically closes or opens the branch to the cooler as a function of the temperature of the reversible working fluid in the system. The heated reversible working fluid flows out of the thermostat directly in front of the filter into the suction branch of the filling-fluid pump, i.e. while avoiding the cooler and the tank. The thermostat thus closes the through-flow of the working fluid into the part of the circuit which contains the cooler and the tank when the working fluid is at a low temperature. When the working fluid reaches the temperature at which the thermostat opens, a portion of the working fluid flows through the connecting branch into the cooler and further into the tank. The thermostat opens fully when the temperature of the working fluid in the tank reaches the optimum value. All the working fluid which returns from the closed circuit flows further only via the cooler into the tank. <IMAGE>

Title: Device for setting up and maintaining the gas pressure in a vaccination gun operated with a high-pressure gas
Inventor: REIM LUDWIG
IPC: A61M5/42
Filed: 1984-02-17
Abstract: The invention claims a device for setting up and maintaining the hydraulic pressure in a vaccination gun operated with a high-pressure gas from a high-pressure gas reservoir. In order to have sufficient working pressure at all times but to be nevertheless able to use up most of the supply of high-pressure gas the gas pressure of the gas emerging from the reservoir is first of all reduced to a value of about 4 to 5 bar in a pressure reducer. Transformation of the medium and the increase of the hydraulic pressure to the value required for adequate operation, for example to 20 bar, then take place in a downstream pressure increasing member. However, it is also possible to set up and maintain much lower pressures.
