Title: Electrophotographic duplicating process - using single exposure with projected optical image of material with photoconductive coating on both sides
Inventor: SATO EIICHI
IPC: G03G13/22
Filed: 1978-07-19
Abstract: The process is carried out with a material having a transparent electrically conductive substrate, coated on both sides with a transparent, insulating, light-sensitive layer. A coloured image, corresp. to an optical image of a master, is produced and the image on one side is transferred to a recording carrier. The side from which the image has been transferred is then charged and the other side is exposed through the coloured image on it, so that a coloured image is formed on one side which corresponds to the image remaining on the other side. In this way, a number of copies is obtd. from a single projection of the optical image of the master. Copies can be made at high speed with small, simple, economical equipment. Each light-sensitive layer pref. consists of a thin layer of a Se alloy and a thin layer of polyvinylcarbazole.
Patent DE-2835866-A1 (DE)
Inventor: SERBERT HARRY DIPL ING DR
IPC: C21B13/08
Filed: 1978-08-16
Abstract: When in the direct reduction of iron-oxide-containing materials in a rotary kiln solid, carbonaceous reducing agents having a high content of volatile constituents are charged to the rotary kiln at its charging end, a reoxidation of the sponge iron can readily occur in the final portion of the reduction zone unless a definite surplus of solid reducing agent is there maintained. To reduce the required surplus while still positively avoiding reoxidation, reducing gases and/or liquid hydrocarbons are introduced in said final portion by means of tubular air nozzles at least partially into the charge located above the air nozzles beginning with at least 75 percent metallization.

Title: Passenger elevator safety system - has each tread mounted above swinging arm operating switch to indicate presence of passenger
Inventor: HENNING GUNTER ING GRAD
IPC: B66B25/00
Filed: 1978-12-23
Abstract: The safety system for a passenger escalator uses a switch for each tread section to establish if there is a load on the tread. If there is no load signal for all the treads, this indicates that there is non-one on the escalator and it can be safely switched on after repair or maintenance has been carried out. The treads are mounted on load carriers (12) at each end of swinging arms (18, 19) above a cross channel (15) mounted across the vertical frame members. Each arm is supported by a bracket near its other end, each having a pivot pin (20, 21) through it, acting as a hinge for the arm. When there is a weight on the tread, one or both of these arms is tilted down against spring force to rest on a stop (24) underneath so that a switch (26) at the centre is operated.
