Title: Video disc players colour detector - distinguishes between proper colour signal and false cross colour signal using line counter system
Inventor: SCHOLZ WERNER DIPL ING
IPC: H04N9/86
Filed: 1975-12-23
Abstract: The colour detector, for video disc players, distinguishes between a proper colour signal and a cross colour signal (caused by colour interference) and only produces its control signal when a proper colour signal is present. A colour signal whose amplitude depends on colour content is passed to a counter that counts the lines in which a threshold is exceeded (the counter responds only to amplitudes above this threshold). The count restarts after a line in which the threshold is not exceeded. At a given count (e.g. 8) the control signal is released that indicates the presence of a proper colour signal.

Patent DE-2638219-A1 (DE)
Inventor: GIAEVER IVAR
IPC: G01N33/553
Filed: 1976-08-25
Abstract: In the novel immunological surface test process, a substrate having a partial monomolecular surface layer comprising an immunologically reactive antigen and an immunologically inert organic compound which separates and surrounds the antigen molecules is initially coated. The coated substrate is then brought into contact with an aqueous medium which contains an immunologically reactive antibody specific to the antigen. The immunological reaction as a result proceeds with substantially improved contact between the layers. In the process, the inert organic compound employed can be bovine serum albumin, ovalbumin or insulin. The antigen can be an anti-immunoglobulin of the antibodies of one of the immunoglobulin IgG class. The novel test process is used for the determination of the presence or absence of pathological antigen/antibodies or complexes thereof in aqueous media, such as, for example, blood sera. <IMAGE>

Title: Installation generating power from tidal energy - has vertically reciprocating ratchet rod carried on pontoon and received in machine room to drive shaft through gear train
Inventor: KRAUSE ALFRED
IPC: F03B13/26
Filed: 1977-05-03
Abstract: A casing (5) is partly submerged in an estuary or other suitable stretch of tidal water. There is a machine room (8) above it. The inside of the casing is open to the tide (5) and contains a pontoon (1) which has suitable ballast (10) to make it float. The pontoon rises and falls inside the casing as tide flows and ebbs. It carries a vertical rod (2) which projects into the machine room. The rod has ratchet gears on both sides which mesh with gear wheels on a stationary shaft (3). The rotation imparted to these is very slow and is magnified by a gear train of seven gears. The resulting output is unidirectional and rapid enough to be a useful source of energy.

Title: Rotatable spring loaded roller blind bar braking mechanism - has weight segments in end socket causing pressure against lock elements
Inventor: SEGERLJUNG BO VALTER
IPC: E06B9/64
Filed: 1977-06-15
Abstract: The braking device is for a rotatable spring-loaded rod or tubular bar fitted for attachment of flexible sheeting or textile for a roller blind, where damage could be caused by accelerated rolling. The bar rotates about a spindle (16) protruding from its end, which can be fixed to a firmly attached holder. A sleeve socket (14), for attachment to the bar (10) end, contains movable weight segments (27), sited to promote friction-action restriction of the bar's speed of rotation, effecting pressure against non-rotatable locking elements on the spindle, under centrifugal force. Excessively rapid rotation after sudden draw release is prevented.
