Patent DE-3834645-A1 (DE)
Inventor: KURATA JUNICHI
IPC: H04N9/82
Filed: 1988-10-11
Abstract: In a first area 20b of a recording medium e.g. a compact disc, a signal is recorded comprising a video format signal multiplexed with a coded information signal e.g. a digital stereo audio signal. In addition graphic codes including picture information occupying at least one channel in a channel group of N (N being a natural number equal to or greater than 2) channels are inserted in a subcode of the coded information signal. Identification code information of the at least one channel is recorded in a second area of the recording medium. Upon playback the identification code information is displayed, and a picture signal corresponding to the graphic codes occupying a channel designated by a picture channel command for designating one channel in the channel group is mixed to the video format signal and displayed as a composite picture. In an area 20a digital audio signals are recorded with a subcode including picture information. Index codes relating to the contents in each area 20a, 20b are recorded in lead-in areas. <IMAGE>

Title: Commissioning station in a rack storage system
Inventor: ULLAL JAGDEESH
IPC: B65G1/137
Filed: 1989-03-21
Abstract: In the area of storage systems, horizontal carousel racks are known, in the case of which, the framework of the carousel rack running around on rails, storage-goods containers filled with storage goods can be conveyed to a region for the removal of storage goods from the storage-goods containers. A plurality of such carousel racks may be provided in a warehouse. The disadvantage with this is that these storage goods which are to be dispatched are removed by the commissioning staff, for one dispatch order in each case, from a storage-goods container in the removal region and are in each case discharged into one container. The invention thus proposes a commissioning station, in a storage system, which is assigned at least one horizontal carousel rack and exhibits a commissioning table on which a plurality of containers, intended for transporting storage goods away, can be placed one beside the other, storage-goods containers of the carousel rack and the containers placed on the commissioning table being located within reach of an operating-staff member who is in essentially one location. The commissioning station is suitable, in particular for storage systems in industry, trade and commerce. <IMAGE>

Patent DE-3929592-A1 (DE)
Inventor: KUBIS HERIBERT DIPL ING
IPC: F02B77/13
Filed: 1989-09-06
Abstract: The invention relates to an oil sump damped against structure-borne noise. Since higher requirements are being made of the reduction in the emission of noise from internal combustion engines, the invention proposes to surround the oil sump (1) with a sump cover (7), the sump cover being made of a single or multiple layer of plastics or steel sheet.

Title: Low pressure plasma spray unit to produce or repair sputter targets - applies metal powder to graphite carrier plate or direct to pref. copper cathode
Inventor: JOHNER GERHARD DR
IPC: C23C4/137
Filed: 1990-05-14
Abstract: Low pressure plasma spraying process for prodn. or repair of sputter targets has the novelty of first involving the generation of a high vacuum in the vacuum chamber. In a second stage the target material in the form of non-gaseous metal powder is applied by a plasma spray pistol. In one design the target is applied to and subsequently removed from the a carrier plate made of graphite with a circumferential groove. In a second design the target material is applied direct to a pref. copper cathode body. During the spray process a controlled increase in pressure is effected as well as a further reduction in oxygen content in the target material. ADVANTAGE - The process avoids the time-consuming use of an adhesive agent and subsequent thermal treatment. Additionally the purity of the target is improved and the possibility of applying other metals and alloys, e.g. rare earths, is introduced.
