Patent DE-3126811-A1 (DE)
Inventor: BEERENS HUGO DR ING
IPC: B21B43/02
Filed: 1981-07-08
Abstract: Rolled stock running out of a rolling mill is parted into lengths suitable for the cooling bed. Rolled stock cross sections of various sizes are retarded both at approach speeds of more than approximately 20 m/sec and slower, alongside the cooling bed in an approach roller feed bed and then transversely conveyed over the cooling bed. In order to avoid requiring an uneconomically long cooling bed as a result of the sequence times of the lengths of rolled stock, three or more longitudinal braking sections are arranged side by side to enable thin lengths at a high approach speed to be retarded in rapid succession and conveyed across to the cooling bed. Covering means of the braking sections are constructed to provide additional retardation of the lengths, e.g. by blowing air, by lowering brake shoes or by the action of linear electromagnetic motors.

The protective steel cap is designed as a means for preventing the steel gas supply line from being pulled out, a supporting element for absorbing vertical forces being arranged between the steel pipe of the gas supply line, or its polyethylene sheathing, and the coaxially running refractory protective tube. The protective steel cap is either welded to the steel pipe or a steel ring, as stop for the protective steel cap, is welded on the steel pipe.
Patent DE-3139742-A1 (DE)
Title: Desk, in particular for office work
Inventor: WAIBEL WALTER
IPC: A47B17/00
Filed: 1981-10-06
Abstract: Transverse frames (7) and longitudinal frames (9) arranged between them are glued on the underside of the work top (1) of a desk on both sides. The longitudinal frames (9) are symmetrical to the longitudinal centre line of the work top (1), but arranged offset inwards from the edge regions of the work top (1) and have guide grooves (9a) for the engagement of bearing elements (19) on the top side of fitted bottom cabinets (18). The fitted bottom cabinets (18) can be displaced laterally in the guide grooves (9a) up to the stop on a vertical limb (7b) of the transverse frame (7) and fixed with their laterally outer wall (18a) to a cross bar (20) which extends between two upright support feet (5) of a support bar (4). The support feet (5) are held with upper fixing portions (6) at the ends of the transverse frames (7). In this manner, an extremely sturdy combination results with a multiplicity of variation possibilities and an attractive visual appearance and functionally appropriate construction of the desk. If no fitted bottom cabinet (18) is provided on one side of the desk, its reinforcement function can be taken over by a bracing device (24) which can be fixed in the guide grooves (9a) of the longitudinal frames (9) and to the cross bar (20) in a corresponding manner like a fitted bottom cabinet arranged there and thus reinforces the angle between the work top (1) and the lateral support bar (4). If the support bar (4) is removed on one side, bearing of the desk can also take place via a holding angle on a shelf wall or the like. <IMAGE>
Patent DE-3139868-A1 (DE)
Title: Probe for heat pumps
Inventor: HUND HELMUT
Filed: 1981-10-07
Abstract: The invention relates to a probe for heat pumps for preferably vertical introduction into the earth. The probe consists of a special-steel or copper pipe which - in the case of vertical installation - is closed at its lower end. The pipe wall has in cross-section an undulating course and is thus flexible. On sinking into the earth, the pipe can consequently easily follow lateral deviations of the borehole from the vertical. It is preferably considered inventive in this connection that the outer wall of the pipe is provided with a thin plastic covering which prevents galvanic element formation taking place in the earth, which would bring about corrosion and pitting.

Filed: 1981-12-02
Abstract: An electrically heated bread-baking device with an automatically operated carriage for the baked material and with an electronic time controller which contains an RC oscillator (21) and a frequency divider as the timer. In order to create a cost-effective and reliable electronic control circuit which, in addition to a more precise time setting and a larger setting range, also has improved temperature compensation, an NTC temperature sensor (22) with a resistor (23) in series with it, and a potentiometer (24), are connected to the input of the timer (21), and a resistor (28), which is connected to the base of a transistor (27), is connected to the output of the timer (21), and the emitter of this transistor is connected to the base of a further transistor (29), and the collectors of the two transistors (27, 29) are connected to a retaining magnet (30) for the carriage for the baked material. <IMAGE>
Patent DE-3149054-A1 (DE)
Title: Ventilation grating
Inventor: SCHRENK HANS
IPC: F24F13/08
Filed: 1981-12-11
Abstract: Ventilation gratings are used in the construction industry for closing off ventilation ducts and the like, in order to prevent penetration of foreign bodies and animals into these ventilation ducts. The ventilation gratings consist of a rectangular frame, grating parts arranged inside this frame and insertion elements situated externally on the frame for coupling with ventilation gratings of the same design. By means of these insertion elements, a number of individual ventilation gratings can in each case be connected to form a compact unit, if they are to be installed at the mouth of ventilation ducts of larger cross-section. The insertion elements, situated externally on two sides of the frame, can be inserted into corresponding openings, which pass through the wall of the frame, on two sides of another ventilation grating. The outwardly projecting insertion element and/or the wall of the continuous opening is designed to be resiliently yielding, so that a type of press-button connection is produced. It is expedient if the openings are designed as slots running parallel to the front plane of the ventilation grating. In this case, it is possible to displace two ventilation gratings, inserted into one another, relative to one another parallel to the grating plane, and it is consequently then also possible to add to three gratings assembled in the form of an angle a fourth ventilation grating which fills the angle.

Title: Device for shutting off the fuel feed to an internal combustion engine
Inventor: COLLONIA HARALD ING GRAD
IPC: F02D41/12
Filed: 1982-04-03
Abstract: A device for shutting off the fuel feed to an internal combustion engine with injection pump in overrun conditions of a motor vehicle comprises a solenoid valve as a function of the fall in the speed of the internal combustion engine for switching the fuel feed on and off. In order to adjust the shut-off threshold and the reconnection threshold of the fuel feed to the characteristics of the internal combustion engine at low cost but nevertheless with considerable fuel saving, the solenoid valve is connected to an output of an idling regulator provided for the same combustion engine, the time response of which regulator has at least one differential component in addition to the proportional component, but if possible a proportional, integral and differential component. The matching of the time components to the dynamic behaviour of the internal combustion engine is moreover the same as for the idling speed control.

Title: Device for feeding fuel in the form of a mixture of water and petrol to a four-stroke internal combustion engine
Inventor: STEFANOV ZVJATKO LILOV DIPL IN
IPC: F02M25/022
Filed: 1982-08-02
Abstract: The device has a water container which is connected to the small venturi of the carburettor by a float chamber, a water pipe, a water nozzle and an atomizer. There are two petrol tanks (6, 7), of which the first tank (7) contains low octane petrol and the second tank (6) contains petrol with an octane number appropriate to the engine. These tanks are connected in parallel with the fuel pump (2) of the engine by a two-way solenoid valve (4). Mounted on the small venturi (8) is an additional water nozzle (11) which is connected to an economizer acceleration pump (17) by a second water pipe (14). This pump is inserted into a float chamber (19) formed at the base of the water container (22). The walls of the container (22) are designed as double walls. The space between them is flowed through by the engine coolant, which is fed in through a jacket (15) built into the two water pipes (14 and 14'). On the side of the carburettor, the ends of the water pipes (14 and 14') are connected to the water nozzles (11, 12) by a solenoid valve (13). The solenoid valve (13) is controlled jointly with the two-way solenoid valve (4) by a temperature sensor (1). A solenoid valve (3) for interrupting the fuel supply when the internal combustion engine is switched off is provided on the idling system of the engine. The water container (22) is equipped with a water level monitor (21). Using the device, it is possible to lower the toxicity of the exhaust gases, to use petrol with a lower octane number and to operate with a fuel/water mixture even at ambient temperatures below the freezing point of water.
Patent DE-3229135-A1 (DE)
Title: Process for the operation of an air/water heat pump, and arrangement for performing the process
Inventor: KUTSCHERA KARLHEINZ DR RER NAT
IPC: F25D21/00
Filed: 1982-08-04
Abstract: In the air temperature region between +10 DEG C and -5 DEG C, the evaporator of air/water heat pumps ices up at high air humidity. When evaporator icing occurs, the time has come where a defrosting process has to be initiated by reversal of the refrigerant circuit. The problem here is to detect icing of the evaporator early and reliably, without considerable outlay. Additionally, according to the invention, the inlet air temperature ( theta LE) at the evaporator and also the evaporation pressure (pV) of the refrigerant in or downstream of the evaporator are measured. Defrosting then occurs when, at the current inlet air temperature ( theta LE), the evaporation pressure (pV) of the refrigerant falls below the defrosting limit pressure (pG) (in the pV- theta LE diagram) associated with the current inlet air temperature ( theta LE) and lying below the evaporation limit pressure (pVW2), which is the lower limit for the working range (A) of the heat pump, at this current inlet air temperature ( theta LE). An arrangement for performing the process is given. <IMAGE>
