Title: Character recognition process - using optical projection onto screen for scanning with photo cells with criteria specified for geometry
Inventor: TIMME MARTIN DIPL PHYS
IPC: G06V10/88
Filed: 1975-01-23
Abstract: An optical character recognition system for alpha numeric characters utilises the projection of the characters onto a screen where photo detectors provide signals to interpreting logic. A pin hole camera is used to project the image and a criteria for optimisation of the aperture size and focal distances is provided to give the best image. The character is decribed by dimensions u, v, the aperture by dimensions s, t and the focal distances by a, b. The optimim criteria for the geometry is given as: - u/s = v/t = a/b + 1.

Title: Continuous line formation from rows of packings - has group of pushers converting by single movement row of packings in line of packings
Inventor: OERTEL WOLFGANG
IPC: B65G47/68
Filed: 1975-02-15
Abstract: continuously running line of packings is produced from rows of side by side positioned packings and includes a group (1) of a number of pushers (1, 1b....) stretching over the whole width of the released row of packings (PR). The pushers are so arranged behind each other that by a single movement of the pusher group (1) a line of packings (PL) is produced from the rwo (PR) of the packings. The pushers (1b) which are engaging the outer packings (P) in the row (PR) are provided in advancing direction inwards bent ends (C) which are working together with stationary points (2). The group of pushers (1) is mounted on a support frame (3) and the distance between individual pushers (1a, 1b....) is adjustable by a tensioning lock (4).

Title: Sacrificial anodes for cathodic protection in sea water - where sound joints are ensured between cast anode and its carrier
Inventor: KLINGENBERG OEYSTEIN F
IPC: C23F13/02
Filed: 1975-03-05
Abstract: In a device for electrolytic anodes, comprising a metal carrier body onto which an anode material is cast, the metal carrier covers 1 side of the anode, and is pref. provided with lugs or tongues which are bent outwards, at least on one side of the carrier, or the carrier may be fitted, at least on one side, with a network of thin elements, esp. expanded metal which is joined on to the carrier. They are used as carriers for critical anodes made of Mg, Al or Zn, e.g. for protecting ships tanks when they are filled with seawater as ballast; the immersed part of drilling platforms and submarine pipes carrying gas or oil from sources on sea beds. With conventional anodes, the exact zone where soln. occurs is unpredictable and, if cracks or other weak bond exists between the anode and its carrier, a lump of anode material may fall off the carrier; apart from increasing anode costs, if the fall of the lump creates a spark ina ship tank, a catastrophe can occur. The invention ensures a sound connection between the carrier and the anode.

Title: Dual circuit air brake with safety interlock - opens both valves if one circuit fails and enables full brake force to be applied
Inventor: BECK SIEGFRIED
IPC: B60T15/04
Filed: 1975-05-02
Abstract: The dual circuit pneumatic brake system has two sets of pressure control valves which operate on the tandem brake cylinder. The valve for the front brakes is fitted with an additional spring so that the front brakes are applied with a higher pressure and slightly before the rear brakes. A safety interlock operates mechanically to open both control valves if one of the circuits fails, so that the full brake pressure is available for the remaining circuit as opposed to the conventional designs in which the additional spring force inhibits the opening of the first valve.

Title: Thin film circuit production method - provides multilayer conducting traces on insulating glass or ceramic substrate
Inventor: MUENZ WOLF-DIETER DR PHIL
IPC: H01L21/70
Filed: 1975-05-23
Abstract: A thin film circuit is provided with multilayer conducting traces on an insulating substrate, which is of ceramic or glass and can possibly be provided with further layers. The conducting traces are produced by applying an adhesive layer and avaporating a copper layer, and then a further copper and gold layer are applied by electroplating. The gold layer is applied directly on the copper layer, omitting a diffusion barrier layer, and then the film circuit is heat trated at a temperature higher than the highest used during subsequent processes or met in operation. Copper diffuses through the gold layer up to its surface, and oxide layer produced on the surface during heat treatment in normal atmosphere, or after treatment in a protective gas, is removed by etching.

On each lamella (1) the metallised sections (3, 11) lying opposite each other are electrically connected by a diode (42) with the electric flow direction of the diode chosen in such a way that the diode through flow is barred when there is a voltage on the metallised sections supporting the permanent polarisation of those areas of the lamellae lying between the metallised sections.
Patent DE-2544268-A1 (DE)
Inventor: NORTH ROBERT JARL
IPC: C09B48/00
Filed: 1975-10-03
Abstract: In the direct preparation of the  gamma  crystalline phase of quinacridone, a corresponding dianilinoterephthalic acid is heated in polyphosphoric acid to a temperature above 70 DEG C, which brings about the ring closure. The reaction mixture is subsequently diluted with an alcohol having 1 to 5 carbon atoms, while the temperature of the alcohol is kept in the range from 0 to 25 DEG C. Finally, the gamma -quinacridone is separated out of the resulting mixture. The  gamma -quinacridone pigment has a deep red metallic shade and can be used as pigment component of red paints, especially architectural coatings and transparent metallic automobile coatings.

Title: Cleaner for used abrasive sand - has particles graded for size before cyclonic separation of sand in water suspension
Inventor: JACKSON EDWARD L
IPC: B03B9/04
Filed: 1976-03-15
Abstract: The installation is for the cleaning and regeneration of abrasive sand for reuse. A gate (16) delivers sand onto a conveyor belt (18) and into a rotating grader (32).

The washer contains water with added detergent injected through pipe layout (52, 54). The water is kept in turbulence by a motor driven agitator (58). The washed sand sinks along the conical bottom and is delivered into a two-stage flotation assembly. The particles of the right size are taken up by an upward moving conveyor belt (110) which delivers it into a rotating drying drum (126).

Title: Transfer system for ceramic blanks on drying - acts in conjunction with multiple cutter transporter belt and roller track
Inventor: BUECKER FRANZ
IPC: B65G47/26
Filed: 1976-03-26
Abstract: The arrangement for transfering ceramic blanks on support plates act in conjunction with a transporter belt. The latter travels with extruded material length through a multiple wire cutter which separates blocks. The blanks are placed on support plates by a relatively simple, careful and highly productive manner. The design of support plates can be independent of the system. The blanks can be deposited on support plates to ensure optimum drying of blanks. In the region of the block separation arrangement (5) is arranged a roller track (7) for briding space between transporter belts (2, 6). The spreading arrangement (5) can be lifted and lowered so that the supports (9) pass through the roller track (7). The supports are situated above the roller track (7) in lifted state and below it when lowered.

Title: Plug hole filling system for baths - has inner and outer pot with separate supply and drainage holes for filling and emptying
Inventor: KUEHNEL KLAUS
IPC: A47K3/00
Filed: 1976-04-22
Abstract: The bath filling system which fills the bath through the plughole uses a two-part pot wherein the supply holes (3) and annular cavity between the inner and outer parts of the top are made large enough to prevent any build up of water during filling. The water is supplied and drained off through separate pipes by means of the inner and outer pot. On tightening up a sealing screw (2) the inner top canbe pressed onto the upper side of the wall of the bath tub and the rubber rings (1) of the outer top can be pressed against the underneath of the bath tub wall on the one hand and against the lower edge of the inner top on the other. A silent steam free filling process is thus achieved.
