Title: Editing equipment for sound and cine film - with second sound track to store audio signal edited sections for displaced scenes
IPC: G03B31/02
Filed: 1974-12-03
Abstract: The sound/cine film is provided with a magnetic track on one side. In conventional systems the sound signal is off-set from the visual scenes due to the separation of the optics and magnetic head. For improved editing the two tracks are arranged together and the sound track is read off before the scenes are projected. The required time lag between audio pick-up and visual projection is simple to arrange using time delay circuits. When the film is edited then the sound track is not lost. An improved editor for films with a sound track on each side, to ensure even film thickness on each side, and with only one track used, records the sound track on the unused track with the offset spacing compensated for. After editing the edited sound track can be transferred back to the original track with the required offset spacing.

Title: Sliding joint high speed train conductor rail - long overlap sections at slight angle to rail
Inventor: ZUREK RUDOLF DIPL ING DR
IPC: B60M1/30
Filed: 1974-12-07
Abstract: A pneumatic suspension system has a pneumatic brake control valve with two inputs (38, 37) from the pneumatic load sensors on the ends of the rear axle. They operate a special double piston (40, 41) on a common operating rod (31) whose displacement modulates the brake force to the rear wheel brakes. The two pistons in different sizes of bore so that the effective thrust area of each is the same as for the other. This enables the control system to generate a pressure on the control rod corresponding to the sum of the two monitor signals, i.e. twice the means value. Asymmetric suspension movements are then easily compensated for without requiring any complicated control linkage.

Patent DE-2505727-A1 (DE)
Title: Retracting ink paste for ball-point pens - contains colloidal soln. of magnetisable particles as additive
Inventor: KUNKEL ERNST
IPC: C09D11/18
Filed: 1975-02-12
Abstract: Use of a colloidal soln. of magnetisable particles in a solvent, as additive to an ink paste for ball-point pens, is claimed. In writing with a ball-point pen, the ink paste is automatically fed to the spherical tip by virtue of the rotation of the ball-point, thereby coating the ball-point continually with a thin film of ink paste. Consequently, the film remaining upon the surface of the ball-point at the end of a writing operation is liable to dry out. This dried ink residue often prevents the pen from functioning satisfactorily immediately upon re-use because the dried ink residue has first to be rubbed off the ball-point by increasing pressure of pen against the writing surface, with the added risk of smudging the same. The present invention overcomes this inconvenience since the ink paste, containing as it does, magnetisable particles, retracts from, and thereby clears, the surface of the ball-point as soon as lifted off the writing surface.
Patent DE-2506163-A1 (DE)
Title: Welding together plastics profiles with shaping head - avoiding glass transition temp at joint
Inventor: STEBLER ANDREAS

Title: Warp knitting machine for producing pile fabrics - avoiding time-consuming replacement and resetting of pile sinkers
Inventor: LIEBRANDT GUNNAR
IPC: D04B23/08
Filed: 1975-09-11
Abstract: Appts. comprises pile sinkers mounted above closing-knocking over bars, pref. with heights which are adjustable together, in groups or individually according to a programme, in order to obtain certain high-low effects in the fabric. The machine may be used to produce pile fabrics with single weave, or pile fabrics of which the foundation fabric also has cross-stabilising long weft threads. Instead of the conventional fixed knocking-over bar, the machine uses reciprocating closing-knocking over bars, preventing the ready-made fabric from moving upwards with upwards movement of the needles. The machine avoids the time-consuming labour of replacement and resetting of the pile sinkers or their holders, and produces pile fabrics with shorter or longer loops with pile sinkers at one height only.

Title: Electromechanical reciprocating drive for radar installation - has electromagnet actuating armature linking aerial via rod mechanism
Inventor: REUPKE ALFRED
IPC: H02K7/065
Filed: 1976-02-19
Abstract: The electromechanical reciprocating drive is used in conjunction with a radar directional aerial installation. The aerial installation can be swept in a horizontal and a vertical direction by means of a spring system actuated by an electromagnet. It consists of a swinging armature connected to the aerial via a rod mechanism. The sum of the moments of inertia of the swinging armature(S), the link rod (Sch) and the directional aerial (R), and the spring constant (C)of the coil spring (F), will determine the beat frequency of the current (I) which excites the electromagnet (E). When the armature (S) swings away from the centre position, it will generate the current, which will convert the pendulum vibration of the armature into a linear motion.
