Title: Oleic coating - to prevent adhesion of excess weld metal splashes during welding
Inventor: SEIPP HANS GUENTER
IPC: B23K35/22
Filed: 1971-08-11
Abstract: A dispersion of 20-30 pts. ammonium lignin sulphate in 2-20 pts. ethyl alcohol dispersed into 60 pts. water, with the addn. of 0.5-1.5 pts. etherial oil such as pine needle oil, can be used to prevent the adhesion of drops and splashes of excess weld metal to the welded sheets during welding. A layer 2-12 um is applied to the surfaces of the material to be welded, allowed to dry and then welding is conducted in the normal manner. Adhesion of drops and splashes of excess weld metal is prevented and even where the coating has been ashed by close contact to the very hot welding zone similar adhesion is prevented. Excess unashed coating can be washed off with water. No fumes are produced during welding and the coating does not affect the performance of the material during welding in any way.

Title: Discontinuous light-absorbing layer prodn - in colour tv tubes
Inventor: KROENES GERHARD
IPC: H01J9/227
Filed: 1972-02-11
Abstract: Production of discontinuous light-absorbing layer which increases the brightness and contrasts of a colour image in a TV tube, comprising forming a layer of a light-sensitive material on a substrate; exposing it to irradiation through a perforated mask; washing away the unexposed (unhardened) parts of the layer; applying a continuous layer of a light-absorbing material; and etching it in such a manner that the remaining hardened parts of the light-sensitive material are removed together with the overlying light-absorbing material, whereas the parts of the latter resting directly on the substrate are not affected, is improved by adding to the light-sensitive material (pref. polyvinyl alcohol sensitised with (NH4)2 Cr2O7) a substance which accelerates the removal of the hardened parts upon etching (pref. with a H2O2 soln.) due to evolution of heat and oxygen. This addition is pref. pulverulent MnO2. The process is accelerated, and a clear pattern is obtained.

Title: Feed roller for thermoplastic film production - with elastic interior and internally cooled for high speed efficiency
Inventor: DINTER PETER
IPC: B29C48/08
Filed: 1972-08-25

Title: Treating bulk material - with gas in fluidised bed controlled by subpressure applied above bed relative to pressure of gas source
Inventor: DANKESREITER GEORG
IPC: F26B3/092
Filed: 1973-02-09
Abstract: Treatment of bulk material is effected by spreading out the material as a flat layer over a gas permeable bed, and passing a gas stream through the bed at the layer at such a flow intensity that the material is fluidised. The gas stream is developed by a subpressure applied above the material layer relative to the pressure of the gas source, esp. the normal pressure, and the flow intensity is varied by altering the subpressure relative to the pressure of the gas source. Very uniform fluidisation of the material. Uniform treatment of the material.
Patent DE-2322936-A1 (DE)
Title: Self cleaning bag filter - having spring mounted bags shaken by periodic flow interruption
Inventor: VOEHRINGER G F
IPC: B01D46/00
Filed: 1973-05-07
Abstract: Bags are held on frames with springs to prevent bag collapse under pressure. A means is provided to interrupt the air flow on a bag (or bags) which causes any air in the bag to reverse its flow and pass through another bag. This gives the bag a shake and removes the dust cake. Flow interruption can be by rotatable flap valve on the top or rotating valve on outlet streams from zones in the filter. Esp. for sprayed paint dust recovery.

Title: IC engine exhaust cleaning reactor - has differential temp detector for control, constructed as single component
Inventor: KOENIG AXEL DR ING
IPC: F02D41/14
Filed: 1973-06-16
Abstract: Secondary combustion air is admitted through a control device which responds to the temp. rise of the catalyst. Two resistance thermometers are contained in a common perforated tube which is screwed into a hub in the exhaust pipe. They have one common lead and are connected in the arms of a measuring bridge as in 2225534. One element is coated with catalyst and the other is left free. The pair thus detect the difference between the gas and the catalyst temperatures.

The supporting devices consist of thread, bristle or needle-like elements of thermally insulating material, whose dimensions are just sufficient for the forces existing after laying of the cable and its cooling; in addition at least one thin-walled supporting hose of thermally insulating material is provided in the cavity between adjacent parts at different temp. levels; it supports these parts during cable laying and before cooling; it is filled with a gas under pressure, and collapses during cooling; the helium cooled part of the cable is supported after laying and cooling by threads and is additionally supported by the hoses during laying and cooling.
Patent DE-2343412-A1 (DE)
Title: Time display by contact point - is of eccentric scales with inner disc rotating in same direction as eccentric motion
Inventor: SCHOELER ECKHARD DR
IPC: G04B19/20
Filed: 1973-08-29
Abstract: The time and hour display of a wristwatch may be by which an inner disc rotates inside a larger stationary ring and contacts it at a travelling point. The inner disc carries the hour figures and the ring on the minute markings. The contact point indicates the minutes and the apex the hours. Instead of the inner ring staff moving in an eccentric circle around the centre of the ring opposite to its own direction of rotation, it is now suggested to drive it separately and let it move in the same direction.
Patent DE-2345626-A1 (DE)
Title: Cooling device for electronic equipment - is designed for units consisting of printed cct. boards
Inventor: WESSELY HERMANN DIPL-ING
IPC: H05K7/20
Filed: 1973-09-10
Abstract: The circuit boards are held in a terminal unit and arranged in a grid in a plane parallel to a wiring plate, through which external signal and supply connections can be made, as well as connections between the boards. Rear sides of terminal units of all assemblies in a unit are very close to a cooling element, through which a coolant flows under pressure; its active cooling surface is a cooling metal film; the cooling element has a frame with coolant inlet and outlet pipes, to whose side the assembly unit is pressed. The flat form of construction enables the space given for cooling to be fully exploited with the possibility of double-sided application.
Patent DE-2346251-A1 (DE)
Title: Nut bolt connection impact wrench - uses hydraulic pressure via lever to pull nut down to desired torque
Inventor: WING GEORGE SEABROOK
IPC: B25B21/00
Filed: 1973-09-13
Abstract: The tool secures two components together by means of a bolt and nut, with predetermined torque and axial loading. A driver is coupled by a detachable piece to one component, and the piece has contact faces preventing it from turning in relation to the component. The driver has a frame with faces working with those on the detachable piece. A head with a main shaft rotates in the frame and is coupled to the nut, having a lever driven by a hydraulic actuator, the pressure in which is adjustable, and which acts against the lever at a safe distance from the shaft. Torque applied to the nut is regulated by the hydraulic pressure, and the detachable piece prevents the frame from turning while the head is running the nut down on the bolt. There is no angular play of the driver in relation to the bolt and nut allowing a speed variation while they are coupled together.
