Title: Dipole aerial for FM-receiver - uses twin cable pulled apart for horizontal part and quarter wavelength impedance matching part
Inventor: HIRABAYASHI KOHICHI
IPC: H01Q9/16
Filed: 1974-02-11
Abstract: The dipole aerial for FM-receivers has a horizontal part and a connecting part. Both parts are produced from a continuous piece of twin cable having an impedance of 150 ohm. The horizontal part is obtained by at least partly pulling apart of the two insulated conductors of the twin cable having a length equal to the half wave length. The connecting part consisting of the not pulled apart portion of the twin cable has an electrical length equal to the product of a quarter wavelength and an odd or even number resulting in aerial input impedance of 75 or 300 ohm respectively.

Title: Electrolytic wound capacitor with narrow anode foil - has cathode foil protruding beyond dielectric strip edges
Inventor: CALLINS HAROLD T
IPC: H01G9/145
Filed: 1974-04-18
Abstract: The wound roll of the electrolytic capacitor consists of a wound set of metal foils and dielectric strips in alternating laminated configuration, the metal foils forming an anode strip of smaller width than that of the dielectric strips. The cathode foil protrudes at one edge beyond the dielectric strip edges. The adjacent cathode foil edges have in a preset region at the roll and contact sections in the form of narrow, elongated grooves of oppositely contacting foil edges. The latter are sealed together along all contact points. The grooves reach beyond the end of the roll and are of width forming a small fraction of the roll diameter. The thermally sealed contact sections are preferably grouped into two configurations, one parallel to the roll diameter axis and the other one at right angles to the first group strips.

Title: Pneumatic tyres prodn - by completing construction and or final vulcanisation of tyre prefabricate on wheel rim
Inventor: JOHANNSEN PETER DIPL PHYS
IPC: B60C3/00
Filed: 1974-11-29
Abstract: Pneumatic automobile tyres are produced by completing the construction and/or the final vulcanisation of the tyre prefabricate on the rim of a suitably arranged automobile wheel. Method results in considerable simplification in, and reduction in time required for tyre prodn. as a result of a reduction in the positioned variations and transportation of the prefabricate. High quality tyres of normal construction can be produced in a range of types. Specifically before the application of the prefabricate, the rim is lined with a non-stick agent, e.g. plastic film. For construction of the tyre beads the edge sections of the rim are lined with partly or completely vulcanised rubber strips for formation of the inner bead parts.

Title: Captive nut expanding tool - has polygonal portion with smooth bore accommodating component screwing into nuts stem
Inventor: MADDOX CHARLES GARY
IPC: B25B27/00
Filed: 1974-11-30
Abstract: The tool expands the stem of a tubular tapped captive nut so as to secure it in place on a component, and comprises a main portion (11) with a smooth-walled bore (12) running in the lengthwise direction and of polygonal external section to take a spanner etc. At one end, the bore is of smaller diameter (13), an annular shoulder being formed (14) where the two sections join. An oblong component (22) fits in the bore, having a top section threaded to take a nut (26), and a bottom and smaller diameter one (24) screwing into the captive nut (28), with a shoulder between the two bearing against that in the main portion. A coupling device, typically a pin (30) fixed to the oblong component and working in a slot (16) in the main portion, prevents the component turning in relation to the latter as the nut (26) is tightened to expand the captive nut stem.

Title: Hydraulically operated fully lined disc brakes - has two semi circular pairs of brake rings with radial force balancing mechanism
Inventor: KLAUE HERMANN DR ING
IPC: F16D55/10
Filed: 1974-12-06
Abstract: The brake for a motor vehicle has the advantage that the radial force applied to the brake carrier is balanced out. This enables the radial expansion of the brakes to apply a greater braking surface to the wheel and to reduce the brake size and weight for given performance. The cylinder and piston operation can be hydraulic or pneumatic. The semi-circular brake segments (29, 30) in the plane of the brake support arms have a distance piece which interlocks and absorbs the radial forces.

Title: Multiple temperature threshold indicator for food freezing equipment - comprises several vessels containing liquids with appropriate dew points
Inventor: KUNERT JUN WERNER
IPC: G01K11/06
Filed: 1975-01-31
Abstract: The temperature indicator is for application to food freezing equipment, in which several vessels each containing a liquid of appropriate dew point are used to indicate whether particular temperature thresholds have been exceeded. Two or more cylindrical vessels (1) are used, each containing a liquid (6) with a dew point corresponding to a temperature above which the freezing equipment interior should not rise. The vessels are inverted so that when the temperature rises to above the threshold concerned, the liquid melts and passes through a small orifice to a display chamber (2), the contents of which may be viewed through a suitable aperture (9) in the chassis of the equipment. The indicator liquids may be coloured, and such units may be incorporated to check the passage of the temperature through many thresholds.

Title: Solenoid operated friction brake for electric motor - with automatic follow up for brake pad wear uses metal discs tilting and jamming on stud
Inventor: KOLB HERMANN
IPC: H02K7/102
Filed: 1975-10-01
Abstract: The brake unit is carried on the outside of the machine housing (1) and the solenoid action is provided by a magnetic plate (11) with an embedded winding. The brake ring with its pads runs in the space between the armature ring (8) and the reaction ring (9), which is located on studs (14) attached to the armature ring.
