Patent DE-3935393-A1 (DE)
Inventor: EVANS ANTHONY COLIN
IPC: F16D65/14
Filed: 1989-10-24
Abstract: A mechanically and hydraulically actuable disc brake has wear adjustment means operable only in hydraulic actuation. Hydraulic fluid introduced into the cylinder 21 causes piston 30 to move into engagement with a brake disc. During initial movement the piston will disengage from frictional engagement with a nut 35 and on further movement will carry nut along adjustment screw 40 to effect adjustment. When the hydraulic pressure rises above a predetermined value, the force of spring 47 will be overcome and results in cam plate 51, screw 40 and nut 35 moving away from cam plate 50 to re-establish frictional engagement between the nut and the piston. Mechanical brake actuation is effected by anticlockwise rotation of cam plate 50 forcing cam plate 51, screw 40, nut 35 and piston 30 towards the brake disc. Resetting of piston can be facilitated by removing anti-rotation stud 53 from engagement with cam plate 51 and rotating the cam plates clockwise to retract the nut 35. Relative rotational positioning of cam plates 50, 51 and bearing race 62 is maintained at all times by a plate 73 pivotally mounted on the race and having pins 71, 72 engaging in a bore and a slot in cam plates 51, 50 respectively. <IMAGE>

Abstract: The use of 1-octadecyl-2-methyl -glycero-3-phosphocholine (Et-18-OCH3) is claimed for treating immunological infections. Dosage of Et-18-OCH3 is 0.1-16 (4-8) mg/ml blood. USE/ADVANTAGE - The Et-18-OCH3 has in vitro activity against HIV infections. In an example to demonstrate the effectiveness of Et-18-OCH3, lymphocytes from HIV infected patients were cultured in the presence of Et-18-CH3 at a concn. of 8 micrograms/ml or 16  micrograms/ml. In the former case an extensive selective destruction of large actively dividing lymphocytes was seen, and the resting cells were also destroyed by the higher concn.

Title: Solvent recovery process during continuous audio- or video-tape mfr.
Inventor: HERMANNS KLAUS DR RER NAT
IPC: F25D17/02
Filed: 1989-11-06
Abstract: The assembly to recover solvents, during mfg. of continuous materials such as audio and video tape, returns major portion of the inert gas and especially nitrogen from the solvent separator (26) through a channel (100) back to the heat exchanger (20). It is heated against the gas flow from the drier (14) and then returned to the drier (14). A smaller portion of the gas is passed back from the solvent separator (26) to the deep temp. section (12) to be cleared of solvent, and to be at least partially extended with part chambers of the vaporised inert gas, especially nitrogen. It is then passed to the lock (16,18) at the drier (14) to give a positive gas inflow and outflow.  A control, pref. valves (102a,100a), is behind the solvent separator (26) to determine the major and minor portions of the gas flow. The deep temp. section (12) has an initial heat exchanger for the liquid nitrogen to be heated for vaporising with a cold carrier to give the required enthalpy for the vaporised nitrogen. A second heat exchanger gives the reheating of the cold carrier for the required enthalpy of the solvent-charged inert nitrogen gas gives cooling to a given temp. and the vapour. A carrier circuit recirculates at the cold carrier between the two heat exchangers.

Title: Guiding device for machine wooden workpiece - has two sliding arms fastened together at fixed angle
Inventor: SOEDER DIERK
IPC: B23Q27/00
Filed: 1990-05-18
Abstract: The wooden workpiece has a curved surface (3) which is defined by a circular arc. This surface is machined by a milling cutter (16) which is guided by two arms (15a, 15b) which are connected to each other to form a fixed included angle. The size of this angle is such that each arm passes through a pivoted guide at each end of the chord (1) of the curve (3). The arms (15a, 15b) thus cause the cutter to move in a circular arc since the rms (15a, 15b) together with the chord (1) form a triangle with the same vertex angle irrespective of the position of each arm in relation to its pivot point. USE - Cutting curved shapes in wooden workpieces.

Title: Replacing or inspecting bonded, prestressed concrete reinforcement - by softening or dissolving bonding resin using heat, solvent or microorganisms so reinforcing bar can be removed
Inventor: HOFMANN UDO
IPC: E04G21/12
Filed: 1991-02-28
Abstract: Changing or inspecting prestressed reinforcing elements in jacket tubes in post-bonded prestressed concrete parts uses bonding material of soluble thermoplastic or thermoset (I) with properties which can be modified at any time by heating, dissolution with a solvent or the action of plastic-digesting micro-organisms, so that the reinforcement is easily removed or examined. Alternatively, the bonding material is a thixotropic silicate e.g. bentonite, in which case the bonding properties are modified, e.g. by removing the prestressing load, or an electroviscous oil, the properties are altered by changing the electric field between two electrodes in the jacket tube. An additional tube or channel is specifically built into the jacket tube to enable introduction of heater, solvent or microorganisms, so that the change in properties of (I) is externally controlled by changing the heater voltage or the flow properties of the solvent, and/or additional means of access are provided, e.g. by drilling into (I) from the edges, joints or ventilation pts. etc. of the concrete part; (I) is polyethylene, polypropylene, polystyrene, polyamide, polyethyleneimine, PVC, PVAC, acrylic resin, polyvinyl ether or linear polyurethane with softening pt. 150-400 deg.C, in which case heat is applied by inserting a heater or by applying a voltage across the ends of the reinforcing bar itself, or (in)organic solvent or micro-organisms are injected through a tube. USE/ADVANTAGE - Reinforcing bars are removed easily from concrete parts for replacement or inspection, without damaging the concrete itself combining easy replacement of prestressing elements (as in construction without an adhesive concrete/reinforcement bond) with the static and financial advantages of bonding after construct

At least one sealing layer may also be provided within the dumped material, and at least one lateral sealing layer (6,7), and/or a floor seal (8), may be provided between the undisturbed ground and the disulphide-rich material. A similar layer (9) may also be placed above the disulphide-rich material. Each sealing layer may be supplemented on the inside of the outside by a layer of a buffer material (10,11,12). USE/ADVANTAGE - Used in reducing the contaminaton of ground water by deposits of disulphide-rich material, esp. spoil from lignite mining operations. Most of the ground water is caused to flow away without coming into contact with the disulphide-rich material, and the quantity of wter seeping through the disulphide-rich material is kept to a minimum. The level of contamination of the water which seeps through the disulphide-rich material is also reduced.
