Patent DE-2936026-A1 (DE)
Title: Thermostatically controlled radiator valve - has cylindrical extension to valve head to maintain constant opening at large valve movements
Inventor: GLIMMERFORS RUNE
IPC: G05D23/02
Filed: 1979-09-06
Abstract: A valve for a central heating system has a valve head (8) whose distance from its seat (6) is thermostatically controlled through an operating rod (9). The valve head (8) has a cylindrical extension (11) below it which protrudes into the inlet passage (5) formed inside the seat (6). When the distance between the head (8) and the seat (6) becomes large, due to a large difference between the true and nominal valve temperatures, the valve opening does not continue to increase in size, since it is now represented by the constant annulus between the extension (11) and the passage (5).

Patent DE-2939902-A1 (DE)
Title: Yarn-drying plant with optimal energy utilisation - from use of heat exchanger and partial recirculation of exhaust gas
Inventor: WISSUSEK WILHELM
IPC: F26B23/00
Filed: 1979-10-02
Abstract: Yarn-drying plant comprises a drying chamber supplied with heated air by a bellows which drives air through a heater to the drying chamber. Preceding the heater is a heat exchanger which pre-heats the ingoing air from the outgoing air from the drying chamber, and, depending upon the moisture content of the exhaust air, mixes a proportion of it with the ingoing air for recirculation. This arrangement gives optimal energy use within the drying plant itself and reduces the power consumption of the heaters.

A bus bar carrying the electric welding current is pref. mounted on the holder arm via an insulating disk; and similar disks are pref. used between the holder arm and head. The advantage is that a good electric contact is made with the welding wire without the use of a contact nozzle which is subject to rapid wear.
Patent DE-2951949-A1 (DE)
Title: Liquid or paste boriding of metals - by heating insulated boron source layer on metal in carburising or (carbo)nitriding atmos.
Inventor: GEYWITZ WALTER DIPL ING
IPC: C23C8/68
Filed: 1979-12-22
Abstract: In a boriding process comprising coating a metal surface with a thin layer of a boron source and then heating the metal in a gas atmos. at 700-1100 deg.C, the novelty is that the boron source layer is covered with an insulating material which inhibits gaseous diffusion and heating is carried out in a carburising, nitriding or carbonitriding atmos. The process allows relatively cheap gas atmospheres to be used and allows simultaneous carburising, nitriding or carbonitriding or non-coated regions of the metal surface.

Patent DE-3004518-A1 (DE)
IPC: B41F17/00
Filed: 1980-02-07
Abstract: The invention refers to a process of coloring (printing) of track-like objects (2), especially ski coverings of thermoplastics, such as olefins, especially high and low pressure polyethylene where, the layer is brought continuously as a hot foil, essentially in a state of fusion, in contact with a print carrier (3), on which there has been deposited a print pattern first of sublimation type and then of diffusion type dye stuff. A transfer of the dye onto foil (2) occurs in a short time and only essentially along a small areal strip perpendicular to the common direction of conveying of layer (2) and print carrier (3). It is preferred that the transfer of dye occurs in the gap between rollers (5, 6) through which the foil and the print carrier are guided. This allows the obtainment of warpage-free print patterns on relatively thin-walled track-like objects in a continuous process, where it is assured that no warpages occur after cooling or reheating of the printed layer. Also, migration problems are avoided by means of short-term locally limited penetration under high pressure in the roller gap.

Abstract: What is disclosed is a conveyor belt made of elastomeric material having a plurality of separate tension bearers extending in the longitudinal direction and taking the form of ropes or cables made of aromatic polyamide, in which special measures are taken to protect the tension bearers susceptible to cutting against being cut during the production of the conventional stepped endless connection: arranged next to each tension bearer and parallel to it is at least one flexible longitudinal member made of material resistant to cutting, for example a steel cord, on which the cutting tool is positively guided along during the exposure of the aramide tension bearers while the endless connection is being produced. In addition, the plane of the tension bearers can be identified by a colour contrast of the core layer in relation to the two covering layers of the conveyor belt.
Patent DE-3105665-A1 (DE)
Title: "Vane vacuum pump with pre-evacuation of the suction chamber, especially for power-assisted braking in motor vehicles"
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F02B3/06
Filed: 1981-02-17
Abstract: It is proposed, for a vane vacuum pump (1) with pre-evacuation of the suction chamber, which pump is preferably employed in power-assisted braking devices for motor vehicles having diesel engines, to design the inlet orifice into the suction chamber as a bore (6) in a narrowly delimited angular range just before dead centre of the extending movement of the vanes. This is more advantageous for manufacturing and machining the pump casing (2) than the hitherto conventional inlet port and, without noticeable disadvantages in terms of the volumetric efficiency, provides further advantages for a geometrically favourable arrangement of the intake (4) and thus the overall size of the unit. In addition, improvements are proposed for the outlet port (22), which, for particular operational states, result in a noticeable reduction in the power required and the fuel consumption. <IMAGE>
