Patent DE-4222086-A1 (DE)
Title: IC engine with combustion air cooler - has reduced nitrous oxide emission at full load or high power at lower combustion air temp.
Inventor: PLEIMLING HELMUT DIPL ING
IPC: F01P7/16
Filed: 1992-07-04
Abstract: The combustion air is fed through at least one cooler where it is temp.-regulated, in order to reduce the harmful emissions from the engine. The air is compressed by an exhaust gas turbocharger and the cooler is a charge air cooler (1). The harmful emissions, in particular nitrous oxide, at full load or high power are reduced by the lowering of the combustion air temp. The harmful emissions, esp. soot particles and/or hydrocarbons, at part load are reduced by raising the combustion air temp. The combustion air is adjusted to 80 to 90 deg.C. at part load or at low power. The combustion air temp. is regulated by controlled throughflow of the combustion air filter with cooling water. USE/ADVANTAGE - In IC engines, to control and reduce harmful emissions by regulating the combustion air temp.

Patent DE-4231195-A1 (DE)
Inventor: VILJANMAA ANTTI
IPC: C14B1/26
Filed: 1992-09-17
Abstract: In a process for stretching leather, a piece of leather to be stretched is continuously gripped and clamped over its width during its transport through a processing section by individual opposite holding members moved in the transport direction. While the piece of leather is further transported, the distance between two holding members arranged side by side is increased at least until the desired final width of the piece of leather is reached, and then the completely stretched piece of leather is released. The clamping force between the holding members is adjustable and is preferably supplied by pneumatic means. A device for carrying out this process has un upper chain arrangement (14) and a lower chain arrangement (12) which extend together along a processing section (19), are urged against each other by elastic transport belts (13 and 15), and have at their surface holding members with leather gripping surfaces which when adjacent endless chains are (24 or 33) divergently guided stretch the piece of leather in the desired manner without requiring manual clamping. This design with transport belts allows a continuous and gentle processing operation to be obtained.
Patent DE-4231338-A1 (DE)
Inventor: WIERES LUDWIG
IPC: B23K1/20
Filed: 1992-09-18
Abstract: In a process for soldering partial areas (5) of a metallic structure (2, 4), a sticky material is applied on the partial areas (5) and then soldering powder is applied thereon, which adheres to the sticky material. The sticky material retains its stickiness up to temperatures of at least 180 DEG , preferably above 200  DEG C, so that when the structure (2, 4) is thermally treated, in particular thermally degreased, no soldering powder is lost. This process is particularly suitable to produce catalyst carrier bodies (1) for catalytic converters of internal combustion engines, since during its production two different connections have to be achieved, i.e. binding the honeycombed body itself (4) to a tubular casing (2) and assembling individual sheet metal layers of the honeycombed structure (4). Different soldering techniques can be successively applied with no loss of the initially applied soldering powder.

Patent DE-4235908-A1 (DE)
Inventor: STROHMUELLER FRANZ
IPC: H01L21/60
Filed: 1992-10-23
Abstract: In a process for soldering a wafer-type semiconductor body to a support, the support is first provided with a solder preform or a fused solder lens and then the semiconductor body is placed on it. In known processes, the solder layer thicknesses are severely limited since lateral solder leakage (due to the semiconductor body settling into the liquid solder) occurs between semiconductor body and support. Furthermore, the known processes require a large expenditure on alignment aids such as expendible solder templates or orientation pits in the solder layer. According to the invention, prior to being soldered to the carrier, the semiconductor body is placed and aligned with the support by a rubbing movement using a force acting on the solder preform perpendicularly to the plane of the joint. During this process, a punctiform joint is produced between the semiconductor body and the solder preform placed on it or the solder lens. Then the arrangement produced in this way is heated in a furnace process to a temperature which is such that the semiconductor body and the support are soldered together. As a result of the rubbing movement, additional alignment aids are unnecessary. If, furthermore, the chosen size of the solder preform or of the solder lens is such that it is approximately equal to the size of the semiconductor body, this prevents the solder leaking out from between semiconductor body and support during soldering. As a result, very thick solder layers can be produced which have a very high thermal load-carrying capacity. <IMAGE>

Title: Furniture frame, in particular table frame
Inventor: KNEILE KARL
IPC: A47B13/06
Filed: 1993-03-26
Abstract: The furniture frame has a stand (column, upright) which is connected via synchronously adjustable articulated arms to a carrier (support) lying thereabove. The stand can be pivoted from an upper use position into a lower use position. The articulated arms are interconnected via a tension (pulling) means. In order to provide legroom for the user while maintaining the synchronism of the articulated arms during the folding or pivoting of the frame, the tension means is arranged substantially sunken in the stand. The tension means thereby lies outside the movement path of the legs of the user of the furniture frame. The furniture frame is particularly suitable for tables used in caravans or the like.

Title: Wound penetrator for a kinetic energy projectile
Inventor: RUDOLF KARL
IPC: F42B12/74
Filed: 1993-04-08
Abstract: A wound penetrator for a kinetic energy projectile consists of a core (2) made of tungsten and of a sheet (8) made of heavy metal. The binding of the sheet (8) made of heavy metal to the core (2), and the binding of the individual turns of the winding to one another are ensured by a metallic binding layer (7). The pressure which is required for the binding is produced by circumferential rollers (3) when the core (2) is being driven in rotation. Straight, calibrated bars for penetrators are produced in a simple and cost-effective manner. There is no need for reworking of the bars because of lack of straightness, incorrect calibration and unbalance. <IMAGE>
