Title: A method of automatic gear selection in a vehicle power transmission
IPC: B60K20/00
Filed: 1981-11-19
Abstract: PCT No. PCT/SE81/00337 Sec. 371 Date Jul. 27, 1982 Sec. 102(e) Date Jul. 27, 1982 PCT Filed Nov. 19, 1981 PCT Pub. No. WO82/01853 PCT Pub. Date Jun. 10, 1982.Method for automatic gear selection in a vehicle power transmission, said selection being catered for by a control system including an electronic unit (1) which, in response to signals representing vehicle speed and engine load, coacts with a programmable read-only memory PROM (28), in which there are stored, for each gear position, alternative speed limits for changing gear to neighboring gears and also limiting values relating to speed change and engine load for selection between said alternative speed limits. To eliminate the risk of unsuitable gear selection for heavy vehicles, e.g. in conjunction with changing gear on a hill, the invention is essentially distinguished in that during travel, data on speed change and engine load are stored in a random access memory RAM (29); that the speed value most recently stored in said RAM before the initiation of the gear selection is compared, together with values stored in said RAM and relating to speed change and engine load at a certain instant before the initiation of the speed change, with values stored in said PROM and relating to speed, speed change and engine load, respectively; that said comparison results in the choice of a certain gear; that in the electronic unit (1) there is generated an output signal representing the selected gear; and that said output signal is fed to an operative means for indicating and/or engaging the selected gear.

Title: Method and device for spray treatment, in particular for spray coating objects.
IPC: B05B14/41
Filed: 1982-01-27
Abstract: In a method and a device for spray treatment, in particular for the spray coating, of objects (1), the spray medium (6) which passes the objects (1) - a so-called overspray (7) - is intercepted by a precipitation surface (9) and subsequently led into a collection trough (10) by a relative movement between the precipitation surface (9) and a stripping element (13). The overspray precipitation formed on the precipitation surface (9) is wetted continuously or for a given time with solvent (17) before and/or until being stripped off from the precipitation surface. As a result, the spray medium's (6) original own consistency or viscosity is maintained or restored. The overspray (7) recovered after this can then be directly fed back to the spray unit (4) as a spray medium (6). <IMAGE>

Title: Striking cap
Inventor: HOLLAND-LETZ HORST DIPL ING
IPC: B25G1/00
Filed: 1982-05-12
Abstract: The invention relates to a striking cap, made of plastic or metal, for strengthening tool handles made of wood. On the side with which it bears against the handle, it has a centric, frustoconical projection exhibiting a bore which narrows first in the form of a funnel and then widens again, and also a plurality of axial slots. Seated on the circumferential surface of the frustoconical projection are protuberances  - or rib-shaped elevations. The striking cap is inserted with this projection into a hole in the wooden handle corresponding to the diameter. When pressing the handle-end of the tool into the hole in the cap, the segments of the projection are spread open and the protuberances - or rib-shaped elevations - are pressed into the wood, with the result that a secure fastening of the cap in the handle body is obtained.

Title: Multiplexing device for cable television systems
Inventor: OHNSORGE HORST DR ING
IPC: H04J14/02
Filed: 1982-10-26
Abstract: In order to transmit several electrical broadband and/or narrowband signals having different frequencies, for example television and sound broadcast programmes with the required signal quality via one optical waveguide, a multiplexing device (MUX) is specified which converts the electrical signals to be transmitted individually or in groups as non-overlapping frequency bands (FB1 to FBn) into optical signals in a parallel arrangement of electro-optical convertors (1 to n), the wavelengths ( lambda 1) of all optical signals produced being approximately identical. These optical signals are subsequently combined by optical means (K) to form an optical multiplex signal which is output to the optical waveguide. Several examples are specified for using this multiplexing device (MUX) and the corresponding demultiplexing device (DMUX) in a cable television system. <IMAGE>

Patent DE-3334854-A1 (DE)
Inventor: DRAUZ KARLHEINZ DIPL CHEM DR
IPC: C07C39/08
Filed: 1983-09-27
Abstract: The production of solutions of hydrogen peroxide in phenol or its derivatives, e.g. hydrocarbyl substituted phenols, halo substituted phenols or phenol ethers, is carried out in a single step. Practically no loss of hydrogen peroxide occurs since a total distillation of hydrogen peroxide together with phenol or phenol derivative is avoided. Simultaneously the solutions obtained are practically free from water. The mixture of phenol or phenol derivative and aqueous hydrogen peroxide is treated with a material that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative or forms an azeotrope with water that boils below the boiling point of hydrogen peroxide, phenol or phenol derivative and the water removed as an azeotrope. The solution of hydrogen peroxide in phenol or phenol derivative which remains behind is suitable for carrying out oxidation reactions and above all, also for hydroxylation reactions. The latter as especially advantageously carried out in the presence of sulfur-, selenium-, or tellurium oxide.

Title: Facade cladding, in particular an adhesive, water-repellant thermal shingle
Inventor: KIRCHNER FRANZ
IPC: E04D1/28
Filed: 1984-01-17
Abstract: When cladding the facades of old and new buildings, the small-particled insulating shingle offers both protection against rain and heat insulation and is also adhesive. In a single working step, structurally optimum weather protection can be applied, without drilling and screwing and in a stress-free manner, by means of commercially available mortar or building adhesive. The insulating body of the shingle is at one and the same time the compensating wedge for a frictionally locking adhesive bonding and the vertical and horizontal stop for precise laying. Depending on its application, the rain-proof cover layer of the shingle can comprise wood, metal, plastic, ceramic, glass, bitumen, etc., while the insulating body can be formed from commercially available adhesive insulating materials.
