Title: Continuously variable cone pulley transmission
Inventor: PATAKY RAIMUND
IPC: F16H61/662
Filed: 1981-08-21
Abstract: The invention relates to a cone pulley transmission with purely hydraulic generation of torque-dependent contact pressures, for which purpose the firmly supported cone pulley actuates - at least on one side of the transmission - a valve part for the load-dependent generation of the contact pressures, the cone pulley being axially slightly displaceable with the aid of a contact pressure device. In order also to allow ratio-dependent contact pressure generation in such a transmission, the valve determining the contact pressure as a function of the torque is supplied with an additional control variable, derived, on the one hand, from the transmission position of the cone pulley axially displaceable for the adjustment of the transmission ratio and, on the other hand, from a torque- and ratio-dependent design of the cam tracks of the contact pressure device.

Title: Hollow mould for producing vessels from plastic
Inventor: LEIS FRED
IPC: B29C49/50
Filed: 1981-09-01
Abstract: For producing vessels, for example bottles, from plastic, hollow moulds consisting of two mould parts are used which, after the introduction of the tubular plastic material in a thermoplastic state, are closed to shape the workpiece and cool it. Each of these mould parts (1, 2) consists of a unified body of a material with high thermal conductivity, for example aluminium, only the surface parts located in the contact surface of the mould parts (1, 2) being formed on a layer (16), firmly bonded thereto, for example by plating, of a material of high hardness, for example steel. It is thus achieved that steel, the material provided with relatively high hardness but relatively low thermal conductivity, only has to be used where it is necessary for reasons of hardness, all other parts of the mould can be produced from a material with high thermal conductivity, for example aluminium. The cooling rate of the workpiece in the mould can thereby be increased and the cycle time for the production of vessels from plastic can be reduced. <IMAGE>

Title: Composite vehicle drive shaft dispensing with universal-joint shaft couplings
Inventor: FISK MELVIN
IPC: B60K17/22
Filed: 1981-10-02
Abstract: A vehicle drive shaft transfers a torque between two components of a vehicle drive train. Misalignments between the power-receiving and the power-take off end of the shaft are compensated by the drive shaft. The drive shaft comprises a composite tubular drive shaft (composite hollow shaft) which is reinforced with carbon fibres and includes a number of adhesively interbonded layers of fibre reinforcing material, embedded in a resin basic material. These layers include at least one layer of high-strength carbon fibres, which are arranged at an angle of +/-40 DEG  to +/-50 DEG  in relation to the longitudinal axis of the shaft, at least one layer of glass fibres which are arranged at an angle of 0 DEG  to +/-15 DEG and at least one layer of glass fibres which are arranged at an angle of +/-75 DEG  to 90 DEG  in relation to the longitudinal axis. In addition to these basic layers, some applications may require further reinforcing layers for fastening purposes. Such reinforcing layers include at least a pair of end sleeves of high-strength carbon fibres, which are fitted to the end pieces of the shaft and are aligned at an angle of +/-75 DEG  to 90 DEG  in relation to the longitudinal axis of the shaft, and/or at least one pair of end sleeves of high-strength fibres, which are fitted on the end pieces of the shaft and are arranged at an angle of +/-40 DEG  to +/-70 DEG in relation to the longitudinal axis.

Title: Support produced with the use of herbs, especially a pillow and herbal cushion
IPC: A47C27/00
Filed: 1981-10-15
Abstract: A support produced with the use of herbs, especially a pillow and herbal cushion, is provided which has a long duration of action and in which dust formation, rot and the formation of mould are substantially avoided. This is achieved in that, in a first illustrative embodiment, a herbal filling (4) is enclosed by a substantially dimensionally stable, air-permeable material, a horsehair cover (7) and a sheep's wool cover (8). The herbal filling (4) is then essentially only compressed when the cushion (3) is used, whereas crumpling and grinding movements, which very quickly crush the herbal filling (4) are avoided. The herbal filling (4) thus does not dry out so quickly, as a result of which a long-term effect is achieved. In a second illustrative embodiment, the filling of the cushion is moistened with herb extract. The moistened cushion filling emits the effective vapours slowly and in a controlled manner, as a result of which the duration of action is enormously increased. <IMAGE>

Title: Connection of rectangular slabs comprising interlocking parts
Inventor: RAUE KLAUS ING GRAD
IPC: E04B7/22
Filed: 1981-10-28
Abstract: The invention relates to the connection of rectangular slabs by means of tongue/groove joints and interlocking parts which produce, on inclination of the slabs e.g. on the roof, a slab surface which is leaktight against leakage water draining off. Such slabs are nowadays made, for example, from material which is a good heat insulator and are laid under the conventional roofing slabs as an under-roof. They are then also intended, as a second protection, to carry away any leakage water which may have penetrated on the slab upper side to the eaves and not to allow it to penetrate into the interior of the house. In contrast to the hitherto known solutions having relatively wide and protruding rebates of the slabs in relation to the top face, the slabs according to the invention permit narrow, less protruding rebates, which are accordingly less susceptible to fracture and nevertheless guarantee the leakage-water tightness. The rebates and grooves do not lie next to one another but above one another and are furthermore characterised in that if specific service conditions (e.g. leakage-water tightness) do not have to be met, certain individual components can be omitted and the solution is thus less expensive.

Title: Device for barriers of underground gas reservoirs
Inventor: FUCHS EBERHARD DIPL ING DR
IPC: E21F17/16
Filed: 1981-12-02
Abstract: The device is to be used on barriers as are provided for sealing, for example, in the utilisation of underground excavations as gas reservoirs. It is the aim of the invention to improve the efficiency and the reliability of combined reservoir barriers of this type and to enable tight damming for higher reservoir pressures. The arrangement for barriers, which essentially consist of one steel barrier system each, formed from cover plate, expansion chamber and frame, and are inserted between a monolithic concrete abutment and a concrete plug and are connected to the rock via seals, is composed of a yielding sealing ring (9), which is tightly connected to the barrier elements and is protected by a supporting-plate ring (10) and stacks (13) of supporting laminae from harmful deformation, and of the slip joints arranged in the concrete abutment and plug. The displacements occurring at higher pressures are thereby compensated for without endangering the tight steel barrier and its connections.
