Patent DE-2811940-A1 (DE)
Title: Gas shielded arc welding appts. - with connections for hand torch or portable set with separate wire feed
Inventor: BLOCH HERBERT
IPC: B23K9/16
Filed: 1978-03-18
Abstract: In an inert-gas welding set, two plug-in connectors for gas, welding current and wire supply are provided on the wheeled plant housing for the connection of a welding nozzle or of a portable appliance. The latter is linked to the plant by a longer connection and has a separate wire feed. An additional control cable connects the portable appliance to the main plant. This avoids the complications of a wire feed of over 3 m. length to remote welding positions and is equally suitable for MIG or MAG welding.

Title: Radial tyre with run flat supporting band - the band being located in the tread region and being held in place by the radial carcass plies
Inventor: MARKOW EDWARD G
IPC: B60C7/14
Filed: 1978-05-13
Abstract: A tyre with radial carcass plies includes in the tread region, a band of high strength metal or plastic held in position by the carcass plies. A material for the band is 0.060 gauge 4130 steel heat treated to 180,000 psi. The band is pref. arcuate in cross section and may be corrugated in the circumferential direction. The band adequately supports the tyre during loss of pressure but does not adversely effect the normal running performance. Indeed by altering the nature of the band the tyre footprint may be altered and a tyre formed with an elongated footprint which shows decreased "buildozing" in soft earth.
Patent DE-2821427-A1 (DE)
Title: Washing machine water control - has mixing valve for solar-heated and cold water to maintain required water temp.
Inventor: REUSCH HEINZ DIPL ING
IPC: E03B7/07
Filed: 1978-05-16
Abstract: The water flow control for a washing machine, where part of the water is heated by solar energy, has >=1 mixer valve in the water feed linking the cold water supply and the feed from the solar-heated water. If the water temp. from the solar-heated source is above the required level, then the valve adds more cold water to the flow. The system prevents water entering the washing machine at higher temps. than desired. There is a comparator circuit to register the water temp. at the outlet of the mixing valve so that, according to a pre-set level, it can operate the mixing valve by an adjustment motor to increase the cold water supply. There can be a number of water feeds, and the valve control can be operated magnetically or thermostatically on pre-set required temp. levels.

Title: Draw strings puller and fastener - has loops locked in tensioned state by locking them between plug inserted into cup
IPC: A43C7/00
Filed: 1978-08-02
Abstract: A draw string is used to hold a shoe lace or the mouth of a bag in a tied state. The free ends of a looped lacing strung through the eyelets of a shoe upper and the like are secured. The device also has a snap fastener having a cup shaped portion through which the free ends of the looped lacing is strung and a plug element in which the free ends of the looped lacing are anchored. The plug element is adapted to be a press fit into the cup-shaped portion of the fastener for clinching the strands of the looped lacing in locked condition. The looped mid portion is drawn tightly by pulling the cord ends outwardly of the open end of the cup-shaped cap while the latter is firmly pressed into abutment against the hem or shoe upper through which the cord is strung to keep the loop tightened. With the cap snugly abutting against the bag or upper shoe last, the plug element is turned to face its tapered portion toward the bell shaped open end of the cap. The tapered end is ultimately inserted into the cap and pressed in place into it.

Title: Digitally controlled power system - has control memory providing instructions program to digital control processor controlling power supplies
Inventor: DOMENICO ROBERT JOSEPH
IPC: H02M3/335
Filed: 1978-10-09
Abstract: The power system includes an analog to digital converter for sensing the difference between a reference voltage and the output voltage. Also included is a digital control processor connected to receive and process the difference or error signal representative of the measured difference and to provide the control pulses to the power supplies. A control memory is connected to the processor to provide a program of instructions to the processor such that the processor provides a change in the width of the control pulses. The power supply thereby provides a programmed change in the output voltage in response to the change of the pulse width of the pair of control pulses.

Title: Electric motor with eccentric rotor - mounted on shaft whose speed is proportional to difference between stator bore and rotor outside diameters
Inventor: CHUNG-HSIN YOUNG
IPC: H02K41/06
Filed: 1979-03-24
Abstract: The motor operates at speeds typically not greater than 1000 rev/min and which has a light rotor weight and low starting current. The stator laminations carry a set of poles with windings. The electrical connections, and any external circuit elements, are arranged such that only half the stator is excited at any one time. The supply may be from alternating current, with routing diodes, or from direct current with a suitable switching regulator. The rotor is eccentrically mounted on the output shaft, and comprises a ring of low loss electrical sheet steel punchings without any windings. the rotor follows the revolving field of the stator by rolling round bearing tracks concentric with the stator bore. The rotor shaft speed is thus given by the difference between the stator pole flux velocity and the rotor peripheral velocity, or, in other words the difference between stator bore and rotor outside diameters. In a practical design the rotor diameter should not be less than 90% of stator bore.
Patent DE-2912144-A1 (DE)
Title: Ferroconcrete structural slabs - with packed steel sheet balls and voids filled with concrete
Inventor: THIMM HARRY
IPC: E04C5/06
Filed: 1979-03-28
Abstract: A new type of reinforcement for ferroconcrete structures consists of hollow steel balls which are produced by deep drawing hemispherical shells and welding them together to form balls. To produce a slab, balls are piled up between steel plates to the required slab dimensions and resistance welded. They are then placed between lost shuttering and all voids between them are filled up by concrete. Several such slabs can be joined to each other or to walls at right angles to them by steel bars which pass through them. This creates structural elements with a high compressive, tensile and torsional strength which has half the weight of conventional ferroconcrete.
