Title: Audio recording and reproduction esp. of speech - uses groove hopping facility to extend duration of important sounds
Inventor: JAHNEL BENNO DIPL-PHYS
IPC: H04N5/76
Filed: 1973-08-30
Abstract: The present invention extends a previous patent to audio, especially speech recordings, e.g. for language instructions, where inexpensive instruments using discs rather than tapes may be preferred. The process consists of recording a sound i.e. a vowel or consonant etc. in more than one groove on the record, which is of the high density type. Where it is required in play-back, for purposes of emphasis, to extend in time the reproduction of a particular sound, the stylus is made to jump a groove. The stylus is held, together with an electro-mechanical pressure converter by an arm connecting it to a carriage. Because of its elastic holder the stylus can follow the grooves in the record until moved to another groove by operation of coils on its top soft iron plate.

Title: Production of thin-film integrated cct. - uses cu-area on au-conductive strip for component-chip soldering/insertion
Inventor: KRAUS HELMUT DR RER NAT
IPC: H05K3/34
Filed: 1973-09-17
Abstract: The detailed manufacturing method refers to an integrated thin film arrangement with adjustable resistors and which permits active and passive components to be connected by choice using micro-welding and soldering techniques into the conductive leads and to stabilise the resistors by an annealing process in an oxydising atmosphere. the substrate can be glass, ceramic, quartz or semi-conductor material and as resistance and adhesive layer is used NiCr, Ni or Ti by evaporation. Use of photo-varnish layers, light exposure and etching produce the required thin film pattern. The conductors are thin strips of Au. Component chips can be inserted by covering the ends of the Au strip with a Cu area for soldering by means of PbSn solder. The main advantage of the method is using a Cu area for chip soldering instead of an Au area.

Title: Foam padded packing container - has paper strip coated with plastics foam only where padding is necessary
Inventor: ANTON HEINZ
IPC: B65D81/03
