Patent DE-3316533-A1 (DE)
Inventor: HANSEN ECKHARD
IPC: A47C1/032
Filed: 1983-05-06
Abstract: The chair has a seat plate (2), which is mounted rotatably on the seat support (1) at the attachment point (3). The backrest support (4) is connected in an articulated manner by an arm (5), extending below the seat plate (2), on the one hand to the seat plate (2) and, on the other hand, by means of a double-jointed lever (10') also to the seat support (1). A gas spring (7), which can be arrested in any desired positions, acts on the backrest support (4) and has the tendency to bring it into the position drawn in continuous lines. When the chair is moved out of the latter position into the position drawn in dot/dashed lines, the seat plate (2) swivels only approximately half as far as the backrest support (4). In this case, it is essential that, despite the synchronous movement of the seat plate (2) and the backrest support (4), no effects arise which cause the shirt to be pulled out. The path of the gas spring increases progressively as a function of the rearward movement of the backrest, with the result that the force acting on the backrest due to the gas spring (7) is likewise greater with the increased inclination of the backrest. <IMAGE>

Title: Infinitely variable gearing with speed/torque control
Inventor: KLEFF HEINRICH
IPC: F16H3/72
Filed: 1983-06-21
Abstract: The purpose of the gearing is infinitely variable torque matching for machines and vehicles. The construction and functioning of the gearing can be seen from Figure 5, in which the gearing is shown together with the driving engine, the controller and the output. The fundamental principle of the variable-speed gearing differs from that of the differential, the epicyclic and the sun wheel gearing. The last-mentioned gearings have a gearing input and two gearing outputs of equal priority in terms of power whereas, in the variable-speed gearing, only one of the two gearing outputs can transmit the full power. Only a small part of the input power can be taken off at the second gearing output, full compensation of the input speed being possible, however. In accordance with this function, speed/torque control at the first gearing output of the variable-speed gearing is possible with the aid of the controller. By virute of the large control range from zero up to a speed ratio of 1:1, the variable-speed gearing additionally has the function of a starting clutch. The major advantage of the variable-speed gearing consists in that it can adapt automatically to the required torque and the driving machine thus always operates in the most favourable speed range. The energy saving compared to the hitherto known gearings is likely to be considerable and the manufacturing costs correspond approximately to those for a four-speed gearbox with a clutch.

Title: Composite material with high tensile strength consisting of a plastics matrix with an embedded reinforcement, and process for the manufacture thereof
Inventor: ALBRECHT JOACHIM DR ING
IPC: B29C70/56
Filed: 1983-06-23
Abstract: A composite material with high tensile strength based on plastic is manufactured by embedding as reinforcement (2) a thermoelastic material, exhibiting a shape-memory effect and based on polymer or metal, in the state of the low-temperature phase in a polymer matrix (1), subjecting the entire assembly to a heat treatment in the temperature range of the transformation to the high-temperature phase of the thermoelastic material, and cooling to ambient temperature. The shape-memory effect (one-way effect for metals) causes in the reinforcement (2) a tensile stress which compressively prestresses the surrounding polymer matrix (1). The reinforcement in the case of a metal is a shape-memory alloy of the type Cu/Al, Cu/Al/Ni, Ni/Ti, Ni/Ti/Cu in the form of wire, wire mesh, sheet metal, tube or coil. <IMAGE>

IPC: G01R31/11
Filed: 1985-02-05
Abstract: In this device, an indicator connected to a sensing line is provided which is formed by an additional electronic switch, such as a diode, located in series with the moisture indicator. To locate the moisture, a pulse echo measuring instrument and converter for generating a cyclically repolarised direct voltage is connected to the sensing line.
