Title: Supercooling of pressurised low-boiling liq. gases - to be delivered to metering device
Inventor: HOESSLIN GERHARD VON DIPL ING
IPC: F17C9/00
Filed: 1979-07-21
Abstract: Liq. gas in an insulated containar which is to be fed to a metering device must be free of bubbles which might be caused by radiant or frictional heat, and hence needs to be supercooled. The liq. gas is fed through a serpentine coil attached to a float-operated lever valve which maintains the surrounding bath of liq. gas at a pressure kept below the pressure of the gas being supercooled. Above the liq gas surface is a check valve to keep the bath at atmospheric pressure, where the temp. is low enough to supercool the liq. gas in the coil. With low m.pt. liq. gases such as nitrogen, bubbles areformed more easily than with carbon dioxide etc., which can be supercooled relatively simply. This device provides a constant stream of purely liq. gas.

Abstract: The invention relates to an attachment stud made of plastic, glass, metal or other material for the holding, fixing, pressing-on of bodies and/or flat blanks, such as posters, plastic films, sheet-metal items, wooden boards and the like. The attachment stud is designed as a universally usable fastening element and it consists of a holding body (2) with cylinder-like portion which can be passed through an opening in a holding surface (15). Mounted axially displaceably in the cylindrical portion is an attachment pin (5) which is subjected to the force of a compression spring. Holding handles (8) are mounted so as to be pivotable about a holding hinge (7) on the end portion of the attachment pin (5) located inside the cylindrical portion. The holding handles (8) are connected to a hinge spring (11). The outer end portions of the holding handles (8) can be passed through guide openings (4) formed in the outer cylindrical surface of the holding body (2). When the holding body (2) is inserted into the opening of the holding surface (15), the attachment pin (5) is pushed into the cylindrical portion such that the outer end portions of the holding handles (8) are drawn into the guide openings (4) and come to rest in the region of the outer cylindrical portion. When the holding body (2) has been inserted through the opening in the holding surface (15), the pressure is relieved from the attachment pin (5) such that it is displaced axially outwards due to the effect of the compression spring (6) and, during this movement, spreads the holding handles open. The latter pivot out of the guide openings (4) and come to rest on the rear wall of the holding surface (15). As a result, the attachment stud (1) is fixed non-displaceably on the holding surface (15). To release the attachment stud (1), it is merely necessary to insert the attachment pin (5) axially into the outer cylindrical portion of the holding body (2), the holding handles (8) being withdrawn back into the region of the guide openings (4). In this position, the holding body (2) is then removed in its entirety from the holding surface (15).

Title: Glide path computer for gliders and powered gliders
Inventor: ROSE REINHARD
IPC: G05D1/06
Filed: 1981-06-23
Abstract: Gliding ratio calculations for gliders have been previously carried out on the basis of an idealised performance curve. This performance curve is changed both by meteorological and flight-physical influences. These facts are met in that the starting point for gliding ratio calculations is formed by a performance curve actually flown. To approach the ideal as closely as possible, gliding ratios of previous flight sections flown can be mixed with the current gliding ratio of the instantaneous flight section.
