Patent DE-2233641-A1 (DE)
Title: Arc welding process - oscillates electrode tip to improve penetration
Inventor: ARIKAWA MASAYASU
IPC: B23K9/30
Filed: 1972-07-08
Abstract: Improved welds are made by traversing the electrode across the bead backwards and forwards as the weld proceeds. At the same time, the intensity of the arc is varied according to the position in relation to the weld. The tendency for drops to fall off the electrode is reduced and better penetration is achieved. The method can be used independent of type of joint, and whether this is horizontal or vertical. The motion can be transmitted by pivoting the welding gun and reciprocating the rear end of this.

Title: DC-DC converter with quenching cct parallel to main thyristor - has recharging thyristor responding to difference between capacitor and supply voltages
Inventor: OSTERRIEDER ALFRED
IPC: H02M1/06
Filed: 1973-09-27
Abstract: The DC/DC converter for supplying d.c. loads from a d.c. source has a main thyristor connected between the source and the load which may be an intermediate stage leading to an inverter. The main thyristor is bridged by the series combination of a capacitor, a second thyristor and a commutating choke. A reversing thyristor is connected in anti-parallel to the secon thyristor. To allow the capacitor to recharge independently of the load, a recharging choke and a recharging thyristor connect one of the capacitor electrodes to the opposite pole of the d.c. source. The recharging thyristor is turned on in each period only when the difference between the supply voltage and the capacitor voltage exceeds a given value. The recharging thyristor turns on a given time before the main thyristor ignites.

Title: Vehicle brake pedal with variable mechanical transmission - has roller and cam coupling with smoothed profile transition for rapid action
Inventor: SCHROETER HANS O
IPC: B60T7/04
Filed: 1973-12-22
Abstract: The vehicle footbrake pedal is fitted with a roller which lies against the profiled edge of a lever which is pivoted on the floor of the vehicle and which presses down on the brake linkage. The first part of the profile has a curved section which then changes to a smoothed profile as the lever is depressed. The profile is so chosen that, when the lever is depressed, the mechanical advantage changes to enable the driver to apply the brakes even harder. The smoothed profile between the curved section and the remainder of the lever is so chosen that when the pedal is suddenly depressed, the roller does not stick in the curved section and suddenly slip out, with a jerky brake action and a noisy operation.

Title: Refrigerator plant temp. difference monitor - provides multipoint direct measurement of temp. differences as current differences to accuracy of tenth of degree C
Inventor: EGGERS HERMANN RAGNAR DIPL ING
IPC: G01K7/20
Filed: 1975-06-11
Abstract: A circuit for the measurement of small temperature differences uses resistance thermometers. They are fed with a constant current through current terminals from which a temperature equivalent voltage is taken off. The circuit can monitor refrigeration plants in which small differences in temperatures along pipe lines have to be measured at a large number of points with an accuracy of 0.1 deg.C. Processing of the measurement is by a time multiplex interrogation of the individual monitoring points. The two outer connection points of a pair of resistance thermometers are connected between a voltage amplifier and with the terminals of two constant current sources. A return lead is connected to the junction of the two thermometers. A selection switch selects pairs of thermometers. The circuit enables temp. differences to be obtained from current differences and does not require measurement of absolute temperatures or currents.
