Title: Gasification of ash-rich oil from petroleum or coal liquefaction - with treatment of quench water to eliminate benzine-washing
Inventor: TIPPMER KURT
IPC: C01B3/36
Filed: 1978-07-08
Abstract: Ash-rich oils are gasified by partial combustion with oxygen or oxygen-enriched gas in a pressure reactor, with quenching and washing of the product gas in water. The wash water is passed to a thickener-decanter and separated into clear wash water, carbon-contg. water and ash sludge. The carbon-contg. water is mixed with the ash-oil feed and returned to the reactor in liquid form or after vaporisation, in place of the steam added to control the conversion. Used for prodn. of synthesis gas mixts. for prepn. of hydrocarbons or organic oxygen-contg. cpds., or reduction gas for processing of metal ores. The usual benzine wash of the quench water to remove carbon is eliminated, together with the benzine losses and cost of equipment for processing and recycling the used benzene.

Title: Electronic common control exchange storage scan - has master clock controlling several sequential control scans of information stores
Inventor: FRANK REINHARD DIPL ING
IPC: H04Q3/42
Filed: 1979-01-30
Abstract: The design is for the control and storage equipment in an electronically controlled telephone exchange, using cyclical scanning of stores to ascertain line and switch block state. The control sequence involves sequential cyclical scanning of storage arrays particular to the establishing of a call through an exchange, and this involves several separate scanning cycles each time separated from each other and tied to the incoming dial pulse information so that the input information by the subscriber is in synchronism with the addressing of stores. The storage units contain the address code and switching information particular to one switching operation so that each serves on e transmission path. The scanning seuqnce allows each store to be released quickly for further operation. Several stores (c1, c2), to cn) are scanned by the first (A1) and second (B1) cycles controlled from the main counter (T) controlling subsidiary counters (U, V). The count is extended to bring other stores (h1....h53... hm in G1 and E1) into the cyclical order.

Title: Automatic stacker for loading moulded bricks onto kiln cars - where bricks stand on edge, and are prevented from falling over by guide rails
Inventor: BRAND HEINZ
IPC: F27D3/12
Filed: 1979-02-12
Abstract: The bricks are moulded by hand or by machine, and are placed on frames or drying pallets from which they are to be transferred to, and stacked on, kiln cars. The transfer and stacking devices form cassettes which hold the bricks so the latter cannot tilt while they are being transferred to the kiln cars. The pref. plant consists of several conveyors, and a tilting device which tilts each brick through 90 degrees so the bricks stand on edge on an intermediate conveyor. This conveyor and the subsequent stacking appts. are fitted with side rails which align the rows of bricks and also prevent the bricks from falling over. The overall result is a reliable stacker which eliminates manual labour.

Title: Solar lamp with detrimental radiation filter - uses cold air curtain directed against irradiated body part, enabling close location of solar lamp to body
Inventor: HUEBNER OTTO
IPC: A61N5/06
Filed: 1979-02-20
Abstract: The lamp is used in a solarium to provide a rapid tanning effect, generating beneficial UV radiation, but filtering out detrimental radiation components. A cold air curtain is provided for the irradiated portion of body, which provides a comfortable temperature enabling close location of the lamp with intermediate filter drive. Preferably the curtain of cold air is additionally used for cooling the lamp. The cold air may be produced by a refrigerator, and suitable baffles may be used for its directioning, providing cold air flow adjustment. The cold air curtain is especially used to offset heat from the lamp IR components. The light source may be a suitable halogen lamp, and the filter is typically designed to separate detrimental short-wave UV radiation, while passing the long wave out.

Title: Recovery of mercury vapour from exhaust gas - by scrubbing exhaust with water then contacting with tin or zinc mesh
Inventor: HOELTER HEINZ ING GRAD
IPC: C22B43/00
Filed: 1979-08-10
Abstract: Hg is recovered from exhaust gas streams by scrubbing the stream with water to condense out the Hg vapour. The resulting mixture is then contacted with Sn or Zn mesh or wadding to form an amalgam (as per DE 2601826). The system described gives further purification of the recycle water so that it can ultimately be discharged to a thickener etc. as a normal waste water stream. This is achieved by further passage through Sn mesh, packing wool or lattice to remove the Hg completely. The Sn treatment forms part of the scrubber liquor recirculation system. The Sn contact surfaces can be in a bed, as a filter in the line or mounted in the liquor holding tank. It can be a combination of several of these.
