Title: Process evacuating e.g. hydrogen@ by means of vacuum pump - using cooled pump interior and reduced gas speed to facilitate evacuation of light elemental gases
Inventor: KONISHI SATOSHI
IPC: F04D19/04
Filed: 1993-03-26
Abstract: A process to mechanically evacuate a vessel by means of a vacuum pump in an evacuation system, uses a turbo-molecular pump or similar. The process incorporates steps to cool the pump interior and at least one gas passage in the vicinity of the pump rear section, in which the speed of the gas molecules within the pump interior and gas passage is reduced, following which evacuation is effected. The gas molecules which are deposited under the cooling effect and are subsequently removed from the condensation area, are ejected in a conventional mechanical fashion. USE/ADVANTAGE - The arrangement facilitates evacuation of light elemental gases with a high molecular speed such as hydrogen, and a reduction of the regeneration frequency

Patent DE-4313312-A1 (DE)
Title: Spreader support ring
IPC: B21D39/20
Filed: 1993-04-23
Abstract: The invention relates to spreader support rings for the support of soft seals (for example, O-rings) which are to be drawn on to cylindrical mandrels which serve as an expanding device for tubes or tube-like articles and which are at the same time loaded with extremely high hydraulic pressures. This spreader support ring is characterised in that it consists of a specific form-memory alloy, in which the effect of pseudoelasticity (also called superelasticity) occurs. In a specific temperature range, these materials exhibit a high degree of elastic stretching, so that the support ring produced from them can execute, without permanent deformation, the high adaptation of diameter required for tube expansion. <IMAGE>

Title: Internal combustion engine with integral piston cooling
Inventor: BONGERS HERMANN DIPL ING
IPC: F01P3/10
Filed: 1993-04-26
Abstract: The formation of carbon monoxide and nitrogen oxide gases in the combustion chamber and in the cylinder of an internal combustion engine is proportional to the volume of the annular gap between piston and cylinder in the area of the piston head up to the front piston ring. The two parameters determining the volume of the annular gap are:     - the piston clearance - the axial distance of the front piston ring from the point of intersection:   outer edge of piston skirt/piston head   A reduction of the volume of the annular gap causes a reduction of carbon monoxide and nitrogen oxide fractions in the exhaust gases. Reducing the piston clearance and shortening the axial interval of the piston ring thereby results in a reduction of the volume of the annular gap and hence a reduction of the carbon monoxide and nitrogen oxide fractions in the exhaust gases. These two design measures are possible only with effective cooling of the piston in the critical area during operation. According to the invention this is achieved by tapping the pressure lubrication system. To do this, a portion of the lubricating oil is led through the piston, by virtue of the special design shape of piston and cylinder, but without an additional component, in order to cool the piston.
Patent DE-4314372-A1 (DE)
Title: Opening flaps for lifting off the text covering of the paper layer system
Inventor: RADEBOLD CLAUS
IPC: B42D15/02
Filed: 1993-04-30
Abstract: The opening of the text side, closed by covering leaves, of the paper layer system takes place 1. by lifting the relatively small covering leaf which bears on the top and is provided with an opening flap. The opening flap bears, by means of an adhesive bonding material, on the undersurface and can thus be easily gripped and pulled up. In the event of further pulling, the relatively small covering leaf is lifted off as far as the border or is lifted off to the full extent from the text side of the letter. Thereafter, the covering leaf which fully covers the text side of the letter can be gripped at the right-hand free border and lifted off as far as the left-hand border of the text side or lifted off completely. 2. Alternatively, the text side of the paper layer system may be covered by a leaf which has an opening flap which, turned over at the border, is bonded onto the text side at the rear - with one bonding strip for fixed closure and one with adhesion properties. The opening flap can consequently be lifted easily and the covering leaf can then be drawn off from the text side. If the text side of the letter is provided with an adhesion closure, the covering leaves lifted off as far as the lateral borders can be fully reapplied over the whole surface area of the text side and the letter can thus be re-closed (e.g. necessary in the case of goods consignments).
