Title: High output semiconductor photocell - has crystals parallel to contacts with charge carriers excited to follow long free paths without recombination
Inventor: HEYSZENAU HEINRICH DR
IPC: H01L31/04
Filed: 1979-08-18
Abstract: The semiconductor photocell - which converts light falling onto it into d.c. - produces a larger output. In previous devices, the charge carriers used have only a very small free path. In a crystal between two contacts, only a reduced part of the optically aligned charge carriers (1) pass to the contacts, most being recombined (2) or passing back again (3). To improve the output, crystals are used which ensure a long free path for the charge carriers and the thickness of the individual cells is selected to have the size of this free path. The return flow is small at normal temperatures. The photocell uses several parallel contacted crystals with their polar axes normal to the contacts. The optically excited charge carriers follow an asymmetrical movement relative to the polar axis.

Title: Nitriding of steel in stream of ammonia gas - where control of ammonia concn. in gas mixt. leaving nitriding container ensures min. consumption of ammonia
Inventor: BOES WERNER
IPC: C23C8/26
Filed: 1980-01-24
Abstract: The steel consists e.g. of a plain- or low alloy- steel placed in a nitriding container, which is heated, and through which NH3 flows. The NH3 concn. is controlled w.r.t. temp. so nitriding occurs in a desired phase, e.g. to obtain epsilon iron nitride (EFN). The NH3 concn. is pref. adjusted to above the phase boundary between the gamma' phase and EFN in the Fe-NH3 phase diagram. Process control during nitriding is pref. achieved by measuring the NH3 is the gas mixt. leaving the container, and by measuring the e.m.f. of a thermocouple used to determine the nitriding temp. The process gives a hard, homogeneous surface layer contg. EFN and epsilon iron carbonitride, with min. NH3 consumption.

Title: Failsafe coupling for pneumatic trailer brake - has venting valve to apply brakes if brake control line is uncoupled
Inventor: MUELLER WOLFGANG DIPL ING
IPC: B60T17/04
Filed: 1980-01-31
Abstract: The failsafe coupling for a trailer air brake has separate connections for the brake supply line and the brake control line. The brake control coupling has a connection to the supply line, via a special valve which is vented when the brake coupling is removed. This provides a rapid indication to the user if the brake coupling is left off. The venting valve is operated by a plunger in the coupling neck and switches the valve between the open and closed settings. The valve operates as a rocker setting and is stable in either setting. If the brake control coupling is left off then the brakes are vented and the failsafe brakes applied, so that the trailer cannot be moved.

Title: Paper pressing roller - uses scraper to prevent ambient air affecting cooling-heating jets
Inventor: SCHIEL CHRISTIAN
IPC: D21F7/06
Filed: 1980-04-09
Abstract: There is a scraper for the paper pressing roller, placed in front of the cooling jets, in the direction of roller rotation. Ambient air is prevented from entering the zone enclosed by the scraper assembly, and the jets. The assembly is formed by a scraper body, together with a scraper blade at the leading side, and incorporating the cooling jets. There is a defined gap between the jets and the scraper, around the roller circumference. The intermediate zone between the two sections is sealed against the ambient atmosphere. The design ensures that the energy consumption for the jets, whether used for cooling or heating the roller, is not increased by the influence of the ambient air at the roller surface.
