Patent DE-4334800-A1 (DE)
Title: Car steering wheel - Has groups of switches incorporated into rim of wheel beneath covering material operating relays by infra-red transmission
Inventor: ALLHOFF-CRAMER ADALBERT
IPC: H01H7/00
Filed: 1993-10-13
Abstract: A steering wheel for a car has "fingertip switches" incorporated into the inner surface of the rim, beneath the covering material. The rim itself is U- shaped in cross-section to hole the necessary cabling. The switches are in groups, the left hand working the lights (winkers, headlamps, spotlamps), the right hand one the radio functions (station selection and loudness) and the middle one at the bottom, the windshield wipers and the door mirrors. All the functions are duplicated by conventional switches on the dashboard so that the driver can choose whichever is more comfortable. Transmission between steering wheel switches and dashboard relays is by infra-red transmitters and receivers. ADVANTAGE The driver does not need to take hands off the steering wheel, therefore giving safer driving
Patent DE-4335214-A1 (DE)
Title: Colour value processing system for colour reproduction process - provides calculated colour values for enlarged or reduced copy using stored original image print colour values
Inventor: DETHARDT HERBERT
IPC: H04N1/393
Filed: 1993-10-15
Abstract: The processing system allows modification of the original colour values obtained by optoelectronic scanning of the image prints of the original in an original raster network (13), to allow the size of the copy to be altered. An output raster network is provided in dependence on the required copy size, the colour values for each of the output image prints calculated from the stored original image print colour values. The calculation of the output image print colour values is effected via an interpolation window, displaced relative to the original raster network, for weighting the original image print colour values with given weighting coefficients. ADVANTAGE - Improved colour reproduction quality of enlarged or reduced copy.

Title: Join seal profile for concrete slabs
IPC: E01C5/08
Filed: 1993-10-25
Abstract: The seal legs (20) facing the join (30) have profile ribs (28) parallel to one another and to the leg, the ribs to reach into the join and be spaced by leg areas (34) of standard thickness. The ribs come in triangular profile and project at least 3mm away from the normal areas between and are set at equal spacing to give a series of mirror-symmetrical profiles. The ribs also project the opposite way off the areas (34) and are identical in shape to the join-penetrating ribs (28), using a projecting profile (32) for positive embedment. The profile expands to its free end and lies half way along the leg so the parts (24,32) bed into the concrete slabs (36,38), using a strand of filler (40) which is pressed in between opposed standard thickness areas. The chambers formed above the fillers are filled with grout etc. (42) or else welded shut to include a supplementary profile.

Abstract: In prepn. of liq. additives (alkylates) for gasoline by catalytic thermal alkylation of a mixt. of olefins and alkanes, esp. of isobutene and isobutane, alkylation is in presence of supercritical water as catalyst.  The process is continuous. Water and the hydrocarbon mixt. are pumped into an alkylation reactor; after a residence period, the prod., with unreacted hydrocarbon, is withdrawn as a hot gas/vapour mixt., which is released to a temp. below the critical pressure of water and is condensed to a liq. phase. The liq. is decanted to give a 1st portion, contg. water and dissolved reaction prods., which is recycled to the alkylator, and a 2nd portion comprising hydrocarbons, from which the alkylate is recovered by fractionation. The 2nd portion may be sepd. into a light gas fraction, which is rejected or condensed and recycled to the alkylator or partly recycled to the separator, and a liq. hydrocarbon fraction, from which the alkylate is sepd. by distn..

Patent DE-4434658-A1 (DE)
Title: Insulating panel and process for producing an insulating panel
IPC: E04B1/76
Filed: 1994-09-28
Abstract: Insulating panels for insulation in the roof region between rafters require means for adaptation to the normally changing spacings between the reafters which form the roof substructure. For this purpose, the insulating panels have to be elastically compressible. Insulating panels which are conventionally produced from hard/tough foamed plastic do not fulfill this requirement. The aim of the invention is thus to provide insulating panels which consist of hard/tough foamed plastic and can be elastically compressed for adaptation to different rafter spacings. For this purpose, the invention proposes to subject the insulating panels or a blank for forming the same, before they are distributed, to partially reversible material deformation. In this arrangement, the cavities enclosed in the foamed plastic are preferably provided with a folded or bent surface. The resulting bends in the surface of the cavities make it possible for the insulating panel to be compressed elastically by hand during mounting between the rafters. A more or less pronounced compression makes it possible for the dimensions of the insulating panels to be changed such that they can be clamped fixedly between differently spaced-apart rafters.

Title: Pilot- or pre-control system for hydraulic control valve of construction machine
Inventor: KAUS WOLFGANG DR

Abstract: A pilot control for hydraulically actuated main control valve (15) includes an adjustable pilot control valve (11) operating at a settable pilot-control pressure received by a control chamber (16,17) of the main control valve (15). In order to improve controllability of working movements in the low speed range, the pilot-control pressure available in the control chamber (16,17) of the main control valve (15) can be reduced to a level which is less than that pressure available at the control output (12) of the pilot-control valve (11).
Patent WO-8800285-A1 (WO)
Inventor: GROSS HELMUT
IPC: F02D41/10
Filed: 1987-06-23
Abstract: Procédé de dosage de carburant, pendant les accélérations, dans une pluralité de cylindres d'un moteur à combustion interne à injection séquentielle. La quantité de carburant à injecter est calculée en fonction du régime, et après détermination du niveau d'accélération, des injections supplémentaires de carburant sont effectuées. Un perfectionnement de ce procédé doit permettre un dosage plus rapide de la quantité accrue de carburant dans le moteur pendant le processus d'accélération. A cet effet, la quantité de carburant calculée est injectée dans au moins un, et de préférence dans chaque cylindre dont la quantité injectée n'a pas encore été aspirée et dont la soupape d'admission n'a pas encore été fermée ou dont le cycle d'admission n'est pas encore terminé. Cela intervient notamment au moment de la production d'un signal de déclenchement (TS) correspondant à la quantité supplémentaire de carburant déterminée en vue de l'accélération.

Title: Process and automatic device for cleaning objects with a liquid cleaning agent
Inventor: FROHN WALTER
IPC: B05B15/555
Filed: 1987-10-09
Abstract: In order to clean objects, in particular paint spray guns, with a liquid cleansing agent, the parts are introduced into a basket (44) rotatively mounted around a vertical axis within an airtight cleaning chamber (44). A pump (84) driven by a compressed-air motor (86) sprays the cleansing agent through spraying nozzles (67, 69) on the parts to be cleaned, thus rotating the basket. The spray gun bodies held in supports in the basket (56) are rinsed with cleansing agent sprayed through their paint inlets and supplied by a branch pipe (58) and adapter (72a, 72b) arranged across the axis of the basket. The used cleansing agent is returned through a filter (42) to a container (36). Another container (34) contains unused cleansing agent. For a first, rough cleaning, the pump (84) supplies used, filtered cleansing agent. For the final cleansing the unused cleansing agent is supplied. After the final cleaning, compressed air is blown into the cleaning chamber (44) and at the same time the air containing cleaning agent vapours is extracted from the cleaning chamber (44) through a venting nozzle (46) by a compressed-air injector (112). The process is automatically controlled, if necessary with a full cleaning option and a rough cleaning option followed by drying.

Abstract: In a process for extracorporal disintegration of kidney stones (2) using shock waves and for generating shock waves in general, in which the amplitude can be varied, without simultaneous and corresponding increase in the pulse duration, a succession of shock waves is generated and amplified in function of the transit time.
