Patent DE-3013518-A1 (DE)
Inventor: MUELLER WALTER DIPL ING
IPC: F25B29/00
Filed: 1980-04-08
Abstract: The heat pump arrangement is constructed for producing a number of different temperature levels from a number of module-like heat pumps (10-10d). Each heat pump contains in each case an evaporator (11), a compressor with a drive (12), a condenser (13) and an expansion valve (14) and thus in each case a self-contained refrigerating circuit, the different heat pumps being connectable together on the heat-source side (15) and/or the heat-sink side (16) by parallel or series connection in each case to form one or more circuits. In this manner, a differentiated matching of the thermodynamic processes in the refrigerating circuits to the requirements of the heat-source and heat-sink side with regard to capacities and temperatures in their temporal courses as well as the construction of heat-pump arrangements with high performance numbers is made possible. <IMAGE>

Title: Netting wire coil former - has cylindrical middle portion and conical flange walls at 30 degrees, and uses computer to determine coil diameter
Inventor: MICHEL KLAUS-MANFRED
IPC: B65H54/32
Filed: 1980-07-09
Abstract: The flange walls (3,4) of the coil former for netting wire extend conically at an angle (alpha) between 20 to 45 deg., preferably 30 deg. For the wire coiling the respective machine incorporates a device determining the change-over points of a coiling drive. For this purpose a computer determines the instantaneous coil diameter from the velocity of the netting wire and the coiling speed, as well as the rated change-over point of the winding drive in dependence on the coil diameter. Then the rated change-over point is compared with the actual value of the position of the wire laying drive. The computer comprises an electronic divider, summator, multiplier and a comparator in series connection. A series representing the coil speed is applied to one divider input, while to its other input is applied a signal representing the feed velocity of the netting wire.

Title: HV insulator assembled from unit sections - has joints made by bayonet fastenings or screw threads
Inventor: HANISCH BERTHOLD DIPL ING DR
IPC: H01B17/02
Filed: 1980-08-02
Abstract: The insulator assembly is built up from several sections which can, if necessary, be readily dismantled. The adjacent sections of fabricated insulators are normally permanently bonded together with adhesive. The insulator (1) consists of several discrete sections (3) each having at least one shed (4).

Title: Heat and/or sound insulation for building roofs, in particular flat roofs
IPC: E04D13/16
Filed: 1981-05-09
Abstract: Such insulation is generally laid in the form of strips or sheets. These strips or sheets comprise a layer of mineral wool, in particular rock wool, to be laid on the roof surface. Such insulations are applied to the building roof as an additional measure or, in the case of old buildings, as a subsequent measure, in order to save energy and, if necessary, also to improve sound insulation. In order to achieve good ageing and weathering resistance on the one hand and non-combustibility and high strength of the insulation on the other hand, whilst enabling simple manufacture and laying at the same time, it is proposed that the layer should consist of lamellae arranged adjacent to one another, in which the mineral fibres essentially run vertically to the roof surface, and that a roof skin should be applied to the upper side of the layer, the edge of which skin projects beyond the layer on at least one side on the uninstalled strips or sheets.

Title: Zirconium-containing sheathed electrode for metal arc welding under protective gas
Inventor: KISHIDA KATSUHIRO
IPC: B23K35/36
Filed: 1981-10-09
Abstract: According to the invention, a description is given of a sheathed electrode for metal arc welding under protective gas, the electrode being suitable, in particular for use in deposition welding to provide a metal mould with a hard surface. The amounts of nickel, silicon, boron, niobium, carbon and zirconium, the essential alloying elements, in the sheathed electrode are such that the metal deposited contains not less than 40% by weight of nickel, 3 to 8% by weight of silicon, 0.1 to 0.5% by weight of boron, 0.3 to 2.0% by weight of niobium, 0.2 to 1.5% by weight of carbon and 0.01 to 0.20% by weight of zirconium. In a preferred embodiment, either nickel wire or iron/nickel wire is used as core wire and the sheathing contains the necessary amounts of all the essential alloying elements, with the exception of nickel. The metal deposited has a high resistance to abrasion and a good sliding property, and the presence of zirconium is very effective in preventing the occurrence of welding cracks.
Patent DE-3141595-A1 (DE)
Title: Method for controlling the fuel-air ratio for an internal combustion engine
Inventor: KONDO TOSHIO
IPC: F02B75/02
Filed: 1981-10-20
Abstract: In the case of a control with return of the fuel-air ratio for an internal combustion engine, an integration correction value is derived from the output signal of a gas sensor which indicates the concentration of an exhaust gas constituent and an engine operation correction value is selected from a memory in which a plurality of engine operation correction values have been previously stored in the form of a chart or table. The engine operation correction value is renewed according to any change in the value of the integration correction value only in a given time interval or in an interval which corresponds to a given number of revolutions of the engine crankshaft from the instant any change is registered in the output signal level of the gas sensor. The engine operation correction value is therefore renewed only when the output signal level of the gas sensor is reliable. If the output signal level of the gas sensor has not varied over a relatively long time interval the integration correction value is set to a standard value whilst the engine operation correction value is not varied using previously stored data.

Title: Scissor lift table
IPC: B66F7/08
Filed: 1981-12-23
Abstract: The invention relates to a scissor lift table for lifting and lowering loads, with a bottom frame and a top frame having a load-carrying table. The object of the invention is to provide a scissor lift table in which the technical complexity is reduced in contrast to the known embodiments. This complexity can arise, for example, if in known scissor lift tables which consist of two scissors or, in the case of complicated tables, of a multiple of this number of scissors, the scissors have to be connected to form a torsionally rigid box. According to the invention, it is therefore proposed that a pair of scissors be arranged between bottom and top frame. In the simple construction, the scissor lift table accordingly consists of only one pair of scissors having two scissor arms with an arrangement of a pair of scissors like lazy tongs between bottom and top frame consisting of a multiple of these scissor arms arranged one above the other.

Title: Process for producing a high-grade fuel, wherein a water-containing fuel, which contains colloidal and chemically bound water, is heat-treated
Inventor: WRANGER TORGILS
IPC: C10F5/00
Filed: 1982-02-16
Abstract: In a process for treating fuel, for example peat, which contains colloid and chemically bound water, the fuel is first dehydrated down to a water content within a first range. Heated water is then passed through the peat mass in a preheater (2) and removed from the peat mass. The preheated peat mass is then fed to a reactor (7) in which it is heated by hot water up to a temperature at which the colloidal water is completely released, while the water chemically bound to the fuel essentially remains. The fuel should be heated very rapidly. The resulting fuel product is then dehydrated under the reaction pressure. <IMAGE>
