IPC: B23B31/16
Filed: 1981-11-10
Abstract: The invention relates to a chuck, in particular for lathes, with chuck jaws guided in a chuck body in such a way as to be adjustable radially to the chuck axis and in engagement with drive members. Also provided are chucking pins guided in such a way as to be adjustable radially to the chuck axis and hydraulic compensating pistons in compensating cylinders, which compensating pistons adjust the chucking pins when pressure is applied. Finally, there is at least one adjusting cylinder with an adjusting piston which can be actuated from the outside for the admission of pressure and is guided radially to the chuck axis. The cylinder spaces, connected to one another, of the compensating cylinders and the adjusting cylinder or adjusting cylinders form a closed hydraulic system. The invention is characterised in that the entire hydraulic system with the chucking pins (5), the compensating cylinders (7) and the adjusting cylinders (8) is arranged together in an annular chucking attachment (1). The chucking attachment (1) can be attached to the chuck body (2) in such a way as to be fixed in terms of rotation about the chuck axis (3) and essentially coaxially. The chucking pins (5) and the adjusting pistons (9), the latter directly or by means of adjusting pins, project at its circumferential surface, each chuck jaw (4) being allocated to one of the adjusting cylinders (8), and the adjusting pistons (9) being adjustable by the chuck jaws (4). <IMAGE>

Title: Eddy-current brake for a vehicle
Inventor: HAGEN HANS DR ING
IPC: H02K49/04
Filed: 1981-12-09
Abstract: In an electrical eddy-current vehicle brake (retarder) a brake-disc rotor is provided which can be coupled to the shaft which is to be braked. The brake-disc rotor is smooth, that is to say is constructed without fan blades. The braking heat which is produced in use is dissipated by means of a separate electrical fan which can be supplied by a generator which is integrated into the eddy-current brake and/or the vehicle battery. If it is possible to supply current to the fan both from a generator and from the vehicle battery, the generator supplies the fan with current during braking operation of the eddy-current brake. If the vehicle, and hence also the eddy-current brake, is stationary, the vehicle's own battery supplies the fan with current when cooling of the brake is desired or necessary. The fan power loss can hence be minimised with advantage.

Title: Device for the injection of liquid fuel for a reciprocating-piston internal-combustion engine
Inventor: FUCHS PETER
IPC: F02M59/36
Filed: 1982-04-01
Abstract: The device comprises a fuel pump (1) and an injection valve (6), which is connected to the pump by way of a pressure line (7). In the pump (1) a controlled overflow valve (4) is provided, from which an overflow line (18) branches off, which by its opening determines the end of the pump delivery. In addition the device comprises a valve (16), which maintains a static pressure in the injection valve (6) and in the pressure line (7). The overflow line (18) is led to the injection valve (6) and opens into a chamber (17) of the injection valve enclosing the end of the valve needle (8) remote from the sealing seat (9). In this way the fuel pressure prevailing in the overflow line on opening of the overflow valve acts as additional closing force on the valve needle, as a result of which a so-called after-dribble due to accidental, repeat opening of the valve needle is prevented. <IMAGE>

Abstract: Two-temperature refrigerator with an evaporator made by a sealed assembly rolling process, and having a first section forming the floor, roof and rear wall of the freezer compartment and a subsequent second section as the space evaporator. The refrigerant introduced from the rear wall into the roof of the freezer compartment flows through the roof in a meandering, low-volume channel, and is thence conducted via the rear wall to the front edge of the floor, whence it passes through a channel, of large cross-section and large volume, likewise meandering back and forth between the lateral borders of the floor, until it reaches a siphon predominantly located in the rear wall and passes from this, via a separator also located at least partially in the rear wall, into the channel of the space evaporator, from which it is fed via a further channel into a vapour dome arranged in the rear wall of the first evaporator section, and from there is sucked out in the vapour phase. <IMAGE>
Patent DE-3225199-A1 (DE)
Inventor: GATTYS FRANZ JOSEF
IPC: G21F9/30
Filed: 1982-07-06
Abstract: The elements are hot-dissolved in nitric acid and the solution from which solid impurities as well as reusable uranium and plutonium have been removed is first subjected to a concentration and a denitration. The denitration is effected in a plurality of stages to cause the selected separation of solution constituents. The oxide waste are transformed into pellets. The denitration is carried out in a first stage with formic acid and in a second stage with paraformaldehyde or oxalic acid. If the material is hardly transformable into pellets, the transformation is carried out with a mineral substance which reacts with water to form a water-insoluble substance (particularly a metal hydroxyde of the main group or secondary group II of the periodic table). Such transformation takes place in a thin layer on the pellets produced. The pellets may be used in that form or may be melted to form glass or ceramic bodies.

Patent DE-3237505-A1 (DE)
Title: Device for separating the sprue from injection mouldings
IPC: B29C45/38
Filed: 1982-10-09
Abstract: In the case of devices for separating the sprue from injection mouldings with subsequent ejection of the sprue, comprising in each case one annular tear-off piston and an annular ejector piston guided in a cylinder, the sprue sometimes remains in the injection channel during the ejector movement or is only partially removed. The intention is to improve a device of this kind in such a way that complete separation of the sprue from the injection moulding and reliable ejection of the sprue from the separating device is guaranteed. For this purpose, it is proposed to provide on the compressed-air feed side of the cylinder space, in the annular tear-off piston, an annular cover which reaches under the annular ejector piston, against which the annular ejector piston rests under spring force and which, in the tear-off end position of the annular tear-off piston, frees the compressed-air feed for the annular ejector piston, and that the injection channel is of cylindrical design on the injection head side.

Title: Process for the operation of an apparatus for the production of fibrous material and also granular material
Inventor: FREI JOSEF
IPC: B03B9/06
Filed: 1982-11-29
Abstract: So that no waste to be separated out as unusable material in the course of the process for producing fibrous material and also granular material from household, agricultural, forestry, organic industry and/or industrial wastes is obtained, the wastes to be processed are subjected firstly to an digestion treatment in an digestion unit (3), and the digested wastes, after the elimination of any metal portions by means of the magnetic separation units (5,6), are divided into three fractions. The division takes place by means of a fractionating unit (10): (a) into a fine fraction not exceeding the desired end product particle size and (b) into a coarse fraction which is easy to process mechanically, and (c) into a coarse fraction which is difficult to process mechanically. The two coarse fractions are thereupon comminuted separately from each other in comminuting units (14,15) which are matched optimally to the coarse fraction to be processed to give the desired final product particle sizes. All three fractions are then dried in a drying unit (18) by heating and drawing off the resulting water vapour to a given maximum residual moisture content and are sterilised, and brought together and fractionated together by means of a further fractionating unit (23) and air separators (24,25,26) into a heavy fraction (29) principally consisting of inorganic granules, into a light fraction (28, 31) principally consisting of organic fibres, and into a dust fraction (33) principally consisting of organic dust particles. For the operation of the drying unit (18), its heating device (34) is operated directly by means of the loose fibrous material produced with this plant, and branched off from the raw material silos (28, 31). <IMAGE>
