Title: Arc welding burner for MIG welding - where water flows through spiral channels for efficient cooling of burner
Inventor: ROESER ANTON
IPC: B23K9/167
Filed: 1977-02-11
Abstract: Arc welding burner uses an inert gas atmos. and pref. a consumable electrode wire travelling along the axis of a gas nozzle. Leads or pipes carrying electric current, inert gas, and a cooling liq. are fitted in the burner handle. Nozzle fits concentrically in a tubular cooling element contg. at least one coolant channel connected to an inlet- and outlet- pipe. The element may be monolithic, where coolant grooves are cut or milled as a spiral in the element, esp. using two opposed spirals. Alternatively, tubes may be brazed or welded onto element to form loops or spirals of tubes along which the coolant flows. The tubes may follow an undulating path parallel with the burner axis, and/or cover 360 degrees of element. When a welding burner is using more than ca. 300 amps, cooling is necessary, pref. using water. The invention provides high cooling efficiency due to the long path taken by the water as it travels through element.

Title: Bistable CRT of storage type - provides peripheral display free zone with insulating carrier of collector electrodes (NL 30.12.77)
Inventor: MCTEAGUE GERALD EMMETT
IPC: H01J31/12
Filed: 1977-05-26
Abstract: The bistable storage screen of the CRT eliminates the effect of halo with the peripheral zone of the screen featuring a layer over the fringe of the collector electrode. The layer extends to the collimation electrode, and its surface potential is lower than that of display zone of the screen, but is close to the potential of the cathode. In addition to conventional electrodes in the electron gun of the tube, the latter includes flood electron guns (34) which emit slow electrons and are set near the vertical deflection plates. Conductive layers (42, 44, 46, 48) on the wall of the tube ensure the focussing and collimation of the slow flood electrons and are fed with stepwise increased potentials, optimum operation being achieved when the highest positive voltage is at the electrode (42). This distributes the slow electrons uniformly over the screen. The screen electrode (52)of the tube face plate is formed by a film of tin oxide and is connected to the junction of resistors (58/60). The film is coated with a dielectric layer (56).

Title: Buffer-type roller conveyor - has rollers driven by induction couplings which interrupt power flow as items accumulate
Inventor: HETTLER PAUL
IPC: B65G47/26
Filed: 1977-09-22
Abstract: The buffer-type roller conveyor gives frictionless braking as the items accumulate. When this happens, the braking forces occuring at the periphery of the driven rollers are absorbed by frictionless induction couplings, which interrupt the power flow from the drive, and restore it when the obstruction is removed. The release torques of the couplings can be adjustable, to allow setting of the accumulation pressure to the minimum to suit the items handled and the length of the buffer section. The rollers can be supplied in sets with release torques set to different values, for insertion at points in the conveyor track.

Patent DE-2827112-A1 (DE)
Inventor: DUFFNER KARL
IPC: B61F5/32
Filed: 1978-06-21
Abstract: The bogies (1) of a rail vehicle with gear wheel drive each have two wheel sets (5, 5a) with the same drive devices (13) and identical travel motors (14) which rotate in the same direction. In order to increase protection against derailing, the stationary wheel pressures of the "critical" running wheels (9, 9a) which experience the greatest load relief during braking when going downhill are greater than the stationary wheel pressures of the other running wheels (8, 8a). This can be brought about for example by additional pretensioning of the springs (17), associated to the critical running wheels (9, 9a), of the primary suspension with respect to their other, otherwise identical springs (16) by means of pretensioning rings. The additional loading of the critical running wheels (9, 9a), is preferably selected such that the safety factors against derailing are at least approximately as great for left-hand and right-hand bends under predetermined operating conditions. <IMAGE>

Title: Communication event period measurement in transmission system - has two counters operating to record periods of line engagement in communication system
Inventor: WOLFRUM ALBERT
IPC: G07C1/00
Filed: 1978-08-31
Abstract: The measurement of periods during which a communication line is occupied in a computer controlled communication system is determined by two cycle counters. One counter operates in a down count mode and the other in an up count mode to maintain the sum constant at 16. At the start of a communication period the one counter state is entered into a totalising counter (T). At the end of the communication the other counter value is added. The value is held in the totalising counter until the next line transmission, when the new state of the down counter is entered. This procedure continues until the end of the monitoring period. The values held in the totalising counter are processed by the main computer.
