Patent DE-4303500-A1 (DE)
Title: Plastics sepn. for polyvinyl chloride and polyethylene terephthalate bottles - by sepg. hollow components contacting heated body and with lower softening point w.r.t. various physical properties e.g. elasticity
Inventor: DEUERLEIN JUERGEN
IPC: B29B17/02
Filed: 1993-02-06
Abstract: The sorting comprises heating the material mixt. to 90-250 deg.C and contacting with a mechanical body. Components with the lowest softening point are sepd. off due to various properties, e.g. elasticity, plasticity, impact behaviour or frictional coefft. A pref. mechanical body comprises a drum (101) with radially projecting pegs (120) round the circumferential surface (105). The pegs (120) penetrate the plastic components (10) with the aid of a feeding device (115). Plant for sorting a mixt. of three or more, in partic. six, different materials may comprise several successive mechanical bodies, opt. combined with existing sepn. processes which are based on density sepn. The plastic components e.g. PVC and PETP are pref. heated to 100-250 deg.C, (150-250 deg.C) esp. 180-230 deg.C. Softer components (10) are penetrated by the mechanical body, the pegs (120) of which exert a given pressure for a defined period. Non-penetrated components (12) are directed to a separate store. Preferred components are accelerated against an impact surface inclined against the direction of the moving components. Components are sorted w.r.t. impact behaviour. Pref. the component mixt. is heated to 100-210 deg.C and contacted with a friction surface which accelerates components with a high coefft. of friction and separates them from those with a lower coefft. of friction. USE/ADVANTAGE - The sepn. is for sorting various types of plastic and is esp. suitable for sorting hollow plastic components e.g. bottles. Sorting of PVC from PETP is obtd. without using organic solvents or fine milling the materials.

Title: Method and device for the communications link of a personal computer to a facsimile unit
Inventor: SIMON WERNER DIPL ING
IPC: H04N1/00
Filed: 1993-04-14
Abstract: In order to be able to use any desired facsimile unit (fax apparatus) as a printer for personal computers, interposed communications networks are required in addition to the data transmission hardware and software in the PC, which have generally become customary in the meantime. If the interposition of the said communications networks is to be avoided, special interfaces are required at the facsimile unit.   A direct connection of the personal computer to any desired facsimile units is made possible by the fact that the personal computer itself produces and transmits the procedures which are otherwise generated by the telecommunications network and are relevant to establishing a link and thus alerts the facsimile unit to receive the communication. Suitable devices are hardware and software components of the personal computer which are additionally equipped with the network-specific handshaking procedures of one or more communications networks. The method makes it possible to use facsimile units as printers, in particular in the case of portable PCs (laptops). <IMAGE>

Title: Device for actuating devices for cans of propellant
Inventor: KOPP VOLKER
IPC: B65D83/14
Filed: 1993-04-23
Abstract: The outlet tubes of pressure cans containing, for example, polyurethane to be foamed very often become blocked. As a result, the contents of the substance to be dispensed which have not been used up become unusable. This is avoided by the invention in that tubes are used which are sufficiently rigid so that, if they are folded back on themselves, they produce a squeeze point which seals off the solvent, and in which folded-back position a holding device holds the tube. Additionally, the free end of the tube can also be sealed (Figure 2).   <IMAGE>

Patent DE-4319516-A1 (DE)
Title: Bed
Inventor: BERNAL CARLOS
IPC: A61G7/05
Filed: 1993-06-14
Abstract: The present invention relates to a bed, in particular to a hospital or nursing bed, which is mounted on four rollers (11, 12, 13, 14) that can be braked and are pivotable about a vertical axis, and which are arranged approximately in the four corner points of the undercarriage (10) of the bed, and which moreover comprises a fifth central roller (21) which can be lowered by a lever to slightly below the rolling plane of the other rollers.

Title: Skid regulating system for motor vehicle - delays ignition timing or interrupts fuel feed to cylinders when skid of drive wheels is too great
Inventor: YAMASHITA TETSUHIRO
IPC: F02D45/00
Filed: 1993-09-03

Title: Computerised control of motor vehicle drive assembly - allows engine-to-flywheel transmission clutch to be re-engaged in circumstances not incurring waste of fuel
Inventor: RIOS MIGUEL DIPL ING
IPC: F02D29/02
Filed: 1993-10-07
Abstract: The control computer economises on fuel by decoupling and stalling the engine for suitable periods while propulsion is maintained by the flywheel, until the driver restores normal working by depressing the accelerator pedal through a given angle and/or at a given rate. To exclude the possibility of a skilled driver deliberately shortening the overrun period by premature pedal depression, the gearbox output shaft speed and gear lever position are measured continuously and a desired accelerator pedal position is read out from memory. The clutch can be re-engaged earlier if the actual pedal position corresponds. ADVANTAGE - The clutch between the engine and flywheel can be engaged in the overrun mode only without engine-braking effect.

USE/ADVANTAGE - For use in a combustion engine. Has a small constructional volume in the axial direction.
Patent DE-4336143-A1 (DE)
Title: Cooling process for turbo engines
Inventor: WUERZINGER ERICH
IPC: F02C7/16
Filed: 1993-10-22
Abstract: In order to cool the operating medium in turbo engines, in particular axial compressors, the invention proposes a process in which the operating medium remains in the turbo engine and does not have to be channelled to an external heat exchanger; the heat content of the operating medium is directed to the outside, via heat conduction, by non-rotating parts of the turbo engine and is then dissipated in a convective manner by means of coolants. This process also permits use in aircraft gas turbines, as a result of which a performance-enhancing effect which has a gentle action on all components and increases the overall efficiency occurrs. The process may likewise be used for cooling components in gas turbines, it being possible to reduce high-pressure compressor cooling air removal, which is detrimental to the overall efficiency.

Title: Modular, V=shaped work holder with adjustable alignment - has two coaxial components with relative translation and rotary motion
Inventor: GIRES MICHEL

By an extra spring compression, the two surfaces are released. ADVANTAGE - Angular position adjustment about vertical axis without a manual tool.
Patent DE-4339489-A1 (DE)
Title: Device for shutting off and releasing a gas flow in a gas pipe
Inventor: GROSSENBACHER CHRISTIAN
IPC: A62C2/04
Filed: 1993-11-19
Abstract: An actuator (3) of a shut-off device (2) in a gas pipe (1) is opened counter to the force of a restoring spring (5), when the switch-off valve (16) is closed, by means of a diaphragm (6) which divides a pressure chamber (7) into a pressure volume (8) and a residual volume (9) when a setting pressure is built up in the pressure volume (8) by means of a compressor (13) which increases the pressure of gas removed from the gas pipe (1) upstream of the actuator (3). When it is being switched off, by opening the switch-off valve (16), gas is conducted through a return line (15), and the pressure in the pressure volume (8) is decreased. By connecting the residual volume (9) to the part of the return line (15) located downstream of the switch-off valve (16) via a compensating line (17), it is ensured that, when the switch-off valve (16) is open, the same pressure prevails on both sides of the diaphragm (6) so that the actuator (3) can be closed reliably by the restoring spring (5). A shut-off and control device (18) acting downstream of the shut-off device (2) is essentially of the same construction as the latter, but it has an additional control element (19) which controls the starting point (pa) to a desired value by means of the actuator (3'). <IMAGE>
