Title: Switch for making temporary measurements on cable cores - makes use of spring mounted contacts which allow for variations in diameter of core
Inventor: BUDICH HANS-PETER
IPC: H01R4/24
Filed: 1974-10-14
Abstract: The application is principally in making temporary test connections to telephone cable cores without the need to strip off insulation and without running the risk of damaging the conductors. The cutting edges (16) which make contact with the cores (8) by piercing the insulation are mounted on a carrier block (15) which is located by dowel pins (21) in the switch base (20). These pins are free to move in the base holes and the carrier is supported by springs (22) around the pins. The cutters thus automatically adjust their position to suit the cable core diameter to give the correct penetration when the cable is pressed against them by the operating cam (35).

Title: Manufacturing fluted waveguides from circular tubes - using die blocks with tapered channel changing from circular to elliptic cross-section
Inventor: TOBITA SUSUMU
IPC: H01Q3/12
Filed: 1974-12-09
Abstract: The system is for manufacturing fluted waveguides. A fluted metal tube is fed through dies made from two separate press blocks with semi circular channels. The cylindrical channel formed when the blocks are closed taper from the input end to the output end so that the metal tube will be compressed in a cone shaped cavity. The tube is moved along a given length when the blocks are separated. They are then closed again to shape a fresh section of tubing. The cross section at the inlet is circular but at the outlet, elliptical. Hence the tube is gradually changed from a circular to an elliptical cross section as it trravels through the disc.

Title: Open end spinning device has fibres fed to rotor - from opening roll in a current of air which is adjustable to control waste removal
Inventor: SRAITR STANISLAV
IPC: D01H4/08
Filed: 1974-12-19
Abstract: A sliver is fed to a toothed opening roller mounted within a housing whereby the sliver is opened into discrete on the periphery of the opening roller and the fibres are fed through a fed duct into a spinning rotor to be spun into yarn. A current of air to fed the fibres is set up in the feed duct, pref. by applying a suction through an exhaust duct to a chamber in which the rotor is mounted and the strength of this current of air is controllable. Trash separated from the sliver passes on the periphery of the opening roller is not attracted into the feed duct by the current of air but passes on the opening roller to a trash removal duct positioned downstream (in the sense of rotation of the opening roller) of the feed duct. The air flow can be adjusted to control trash removal and prevent trash from entering the feed duct.

Title: Radio link from central to mobile stations - allows central control to turn off aid-summoning alarm signal from mobile stations using radio control signal
Inventor: VORWERK HELMUT DIPL ING
IPC: H04B7/26
Filed: 1975-04-10
Abstract: The radio link, from a central control to several mobile stations (e.g. taxis), allows a switched-on emergency signal generator in the mobile station to be turned off after it has fulfilled its purpose without requiring access to the radio equipment in the mobile station i.e. to be turned off by the central control after the taxi driver has switched it on to summon help in an emergency (e.g. an accident). The advantage lies in preventing the vehicle batteries being fully discharged by an otherwise continuously operating emergency signal. The central station simply transmits a turn-off signal from a special generator to the mobile station.
