Title: Tubes with metallised bores, esp optical fibres - obtd by feeding metal wire into the bore when drawing the fibre
Inventor: LEHLE HELMUT
IPC: B29C48/10
Filed: 1974-11-06
Abstract: Process for mfg. small tubes and internally-metallised hollow fibres, the novelty being that in mfg. hollow fibres of glass or plastics by conventional processeS, a metal fibre or wire is simultaneously fed into the centre of the bore and evapd. by high-frequency induction heating.

Title: Multi-channel status indication system - uses two coupled memories for old and new status comparison to select pulse rate for display
Inventor: HERKERT HANS DIPL ING
IPC: G08B26/00
Filed: 1975-03-27
Abstract: The multi-channel status indicator utilises two coupled memory stages to respond to changes in status and to use a flickering lamp display operating at slow and fast rates to indicate changes from 0 to 1 and 1 to 0 respectively. A memory stage (1) responds to a change in status when a wire signal (E) is applied, and the old status is stored in a separate memory (2). When a completion signal (Q) is spplied, the information is transferred from memory (1) to memory (2). A data selector circuit compares the memory outputs (Q1, Q2) and generates either a slow or fast pulse rate (A) for the displays over 'D' type flip-flops. A counter (8) and decoder (7) operated from a clock provide clock signals for the flip-flops.

Title: Energy converter for wave motion - uses floats connected to piston water pumps to feed water turbine
Inventor: GYOENGY KALMAN
IPC: F03B13/16
Filed: 1975-09-11
Abstract: Conversion of water motion into usable energy where the vertical, natural motion is converted into energy by floats, especially for generating electrical current. The vertical motion of the water is transmitted by means of a float and a pump rod to a piston water pump. This pump can work in different positions according to the tides. Water from this pump is pumped into a distributor tank from where it is fed to a turbine. Water not required by the turbine is automatically pumped from the distributor tank into a higher water store. On pressure drop, or pump stoppage, there is an automatic return of the water from the water store via. same distributor and pipe system to the turbine so that there is uninterrupted turbine operation.

Title: Ultrasonic vehicle burglar alarm - has operational state indicator lamp which shows that ultrasonic signal is being produced and successfully monitored
Inventor: BAUMGARTL WALTRAUD
IPC: B60R25/10
Filed: 1976-04-05
Abstract: An ultrasonic vehicle burglar alarm consists of an ultrasonic signal generator and corresponding microphone receiver which detect any disturbance in the ultrasonic signal transmission characteristics inside the vehicle when the alarm is primed. The device also has a lamp indicator showing that the system is properly operational before the vehicle is left by its owner. An ultrasonic signal generator (1, 3) produces an approximately 40 KHz signal inside the vehicle when the device is switched on. A microphone (4) also in the vehicle, details this signal which is then amplified (2), rectified (5), amplified (6) and fed to an alarm (7). The circuitry detects any significant change in the reflected ultrasonic signals inside the vehicle. The rectifier (5) output is fed to an AND gate (9) together with a time delayed (8) alarm priming signal. If the ultrasonic signal is being produced and received, this activates an indicator (10) to show that the system is operational.

Title: Microswitch with axially magnetised elements - has switching magnet facing magnetised elements causing polarisation change on any slight motion
Inventor: LUEHN OSKAR
IPC: H01H36/00
Filed: 1976-06-15
Abstract: The magnets (4-7) are mounted on rotary holders (2, 3) of the microswitch, and are magnetised in the preferred direction. They are mounted opposite a switching magnet (9). At the slightest rotary motion of the magnets in relation to the switching magnets a pole change is attained. According to the direction of rotation the switching magnet is thus attracted or repulsed and actuates the contacts. Preferably the arrangement of the magnetic elements compensates the magnetic field effective in both direction of rotation with the result that the lever (13) requires a very small actuating force. The magnets may be longitudinally slidable into the magnetic field of the switching magnet.
