Title: Oil lubricating system for intermediary axle transmission - has oil conveying threads with air scoop to push oil at outlet to drive shaft
Inventor: ROCKSTROH FRIEDBERT
IPC: B60K17/36
Filed: 1977-07-22
Abstract: The oil lubricating system is for the intermediary axle transmission of a motor vehicle, having an oil collection trap which receives oil centrifugally ejected from the gear wheels and conducts this via channels to an oil conveying thread. An air scoop is located at the outlet to the oil conveying thread and couples a throttle point with the outer bearing of the drive shaft. A spur gear draws oil from the oil sump and conveys it to the oil trap and via channels to the thread. The lubricating system operates effectively over hilly country.

Title: Applicator for coatings such as chocolate on confectionery - ensures uniform penetration of surfaces roughened by nuts, fruits etc.
Inventor: SOLLICH HELMUT
IPC: A23G3/22
Filed: 1977-08-29
Abstract: A fluid mass such as chocolate is applied as a coating to sweets, baked articles, etc., as it falls from the bottom opening of a container, on to the articles moved on a conveyor. In the outlet from the container, a rotating cylinder is arranged and projects partly into the mass. The lowest point of the cylinder is relatively close to the moving goods, and immediately behind them, a scraper blade for the material on the cylinder is fitted. Ensure a uniform coating esp. on goods the surface of which is roughened by trimmings such as nuts, without trapping air beneath. The operation is carried out correctly and at high speed, since the turbulence set up assists the penetration by the mass.

Title: Guide for EDM wire electrode - has multiple orifices for coolant in ring around centre wire guide
Inventor: FILSINGER WERNER
IPC: B23H7/10
Filed: 1978-03-06
Abstract: The wire electrode of a spark erosion machine is cooled by jets of dielectric fluid from a nozzle which serves as a guide. The nozzle (25) has an upper plate (27) with a ring of holes (26) surrounding a central guide hole for the electrode (10). The axes of the holes are inclined to the axis of the guide hole so that the jets of fluid impinge on the electrode.

Title: Function testing of electronically phase controlled aerial - feeds into all aerial memories logic units, sets phase shifter and checks general adjustment to logic unity
Inventor: REHER PETER
IPC: H01Q3/26
Filed: 1978-06-16
Abstract: The electronic, phase controlled aerial has digital phase shifters, associated with aerial radiation elements. For its function testing the information about possible interference is provided by a continuous sequential unity and zero test. Only the logic unities are fed as input signals in all radiation element input memories. Alternately only logic zeroes are supplied to the memories. Then after adjustment of the phase shifters a check is carried out, if all phase shift stages are adjusted to a logic unity, or zero, as well as if all input memories are also correspondingly adjusted. The preferred application is in large aerials of radar systems. If the phase shift stages or the output memories show a faulty switching condition, a fault indicating signal is transmitted to the operational system, where a lmap panel preferably indicates the respective faulty aerial element.

Title: Oil slick disposal - by electrolytic thermal pyrolysis between towed electrode plates
Inventor: REZNIK SZMUEL DR
IPC: B01D17/02
Filed: 1978-07-25
Abstract: Oil slicks or other oil residues floating on surface waters are removed by electrolytic and thermal pyrolysis and decompsn. A buoyant structure, towed by a boat, carries a horizontal lower anode plate and a parallel cathode plate above it at a distance of 1 mm. to 1 m. A voltage of 2-10,000 V (12-50 V) is applied between the electrodes and the oil is decomposed at a current density of 0.1-100A/mm2 (1-50A/mm2). This makes use of the large amt. of energy released by an electrolytic-thermal decompsn. of NO2 for the pyrolytic decompsn. of oil slicks to volatile or innocuous prods. of dissociation.

Title: Textile sizing with simultaneous PVA-contg. waste water purificn. - by passing textile impregnated with inorganic salt mixt. through the waste water
Inventor: FISCHER KLAUS DR
IPC: D06M15/333
Filed: 1978-07-29
Abstract: Simultaneous textile sizing and PVA removal from waste waters takes place by (1) impregnating the textile with boric acid or borates together with other inorganic salts, (2) contacting the treated textile with a PVA-contg. waste water and (3) sepg. the pptd. PVA gel. Waste waters, obtd. in desizing textiles sized with PVA can be purified from PVA, as PVA alone is pptd., it is septd. from other waste water components, e.g. surfactants. The residual liquor, remaining after PVA pptn., can be re-used as wash-water in desizing processes. The use of the textile carrier prevents waste water loading with salt. PVA removal from waste water, measured as COD, is >50%.

Title: Multiple head slotting machine - has two pumps to supply oil to hydraulic clamps to reduce power requirements
Inventor: BLINOV ALEKSEI VLADIMIROVITSCH
IPC: B23Q3/06
Filed: 1978-09-12
Abstract: A multiple head slotting machine has hydraulically operated clamps for the workpiece. The hydraulic fluid is supplied from two pumps with their delivery pressures limited by safety valves and connected to a common control valve. The larger pump is used to operate the clamps when the workpieces are clamped at the beginning of a machining operation. The smaller pump is then used to make good any leakage losses and maintain the necessary working pressure. The use of two pumps reduces the total power requirements of the slotting machine.
