Title: Optical detector system for safety of vehicles - laser transmitter operates with active responder giving distance data
IPC: G01S17/931
Filed: 1973-10-19
Abstract: The system can operate in fog and vehicle control signals are derived from the receiver. A moving vehicle (V1) carries a transmitter receiver operating in association with responders (V2, V2o) comprising a reflector (6) in front of which is a liquid crystal (5) connected to a modulator (7). An identical responder (8, 9, 10) operates in the opposite direction. The transmitter (1) comprises a diode laser modulated by a generator (11). Received signals (12) are frequency transposed (17, 18) by two frequency generators (13, 14) to obtain the required information. After filtering (19) the signals are passed to a tracking loop (20) connected to a counter (23 to 27) followed by a digital to analogue converter (25, to 29) to give distance data. The diode laser is responsive to wavelength of from one to several microns.

IPC: A61K31/135
Filed: 1974-09-24
Abstract: Mixing of an aqueous suspension of a catecholamine in the presence of disodium edetate and sodium metabisulphite with active charcoal at a pH of 4.5 under nitrogen and filtration results in a catecholamine solution with less than 1 ppm heavy metals, from which the catecholamine is precipitated and converted into a water-soluble complex with a thiol derivative of an  alpha -amino acid by addition of a 0.5 - 5 % by weight aqueous solution of the thiolic compound together with an acid or a compound with an acid reaction, and subsequent addition of a base to a pH of 6.0 - 7.5.

Title: Cylinder lock with protection against drilling out - has carbide inserts deflected by drill (NL071076)
Inventor: TIETZ WERNER
IPC: E05B15/16
Filed: 1976-02-13
Abstract: The cylinder lock is protected against drilling out, ensuring a high degree of security against forcing of the lock. The protection is provided by carbide pin inserts which are deflected by the drill. The carbide pins (5, 6) are moved through the aligned escape and entry holes in the lock housing and cylinder core (2) which results in locking when these holes are partly occupied by pins. These carbide pins can be positioned in bores of the cylinder core, and are displaced into the housing when an attempt is made to drill the lock out. Instead of pins, carbide plates sliding in corresponding slots can be used. The pins or plates are displaced into the locking position when the drill contacts them. The ends of the pins are arranged so that the drill penetration path is completely blocked.

Title: Cinematography film drive - uses a ratchet operated by a cam to achieve discontinuous film motion
IPC: G03B21/44
Filed: 1976-06-04
Abstract: The cinematography film drive mechanism moves the film the required discontinuous stop-go motion by means of a sprocket wheel driven by a rachet controlled by a cam. The film (3) is moved past the optical aperture (5) by means of sprockets (2) engaging in holes (4) in the film. The sprocket-wheel (1) is turned in a stepped motion by means of a rachet (1a). The two sides of the rachet (8, 9) are kept in contact with a spring (19). The drive motion comes from a bracket (13, 15, 16) pivoting around a shaft (6) concentric with the sprocket wheel, and engaging with a pin (12) on the rachet. A cam (18) and a spring (17) cause the bracket (13, 15, 16) to move to and fro (14) to drive the rachet. Reverse motion of the sprocket wheel is prevented by a lever (23).
