Patent DE-1966976-A1 (DE)
Title: Selective control of operational data in press-moulded sheets mfr. - utilising pressure differentials during pressing for control of processing parameters for sheet immediately following sheet
Inventor: MAY HANS-ALBRECHT
IPC: B27N3/20
Filed: 1969-09-11
Abstract: In selection of operational data for mfr. of press-moulded sheets deviation from a theoretical (rated) curve of the counter-pressure exerted by the sheet being press-moulded, during compression and curing, is utilised for controlling the operational data for the raw matls of the successive sheet. The operational data concern e.g. humidity content of component woodchips, particle size distribution, and even spread of the chips just upstream of the press.

Title: Winding-on an intermediate yarn store - for smooth and consistent take-up with fluctuating demand
Inventor: PFEIFLE DIETER DIPL-ING
IPC: B65H51/22
Filed: 1973-02-20
Abstract: An inter. yarn store, for knitting and warp knitting machines where the yarn requirement varies shock-wise, comprises a toothed pulley with a peripheral groove which transfers the yarn at the processing speed to a motor driven inter. storage bowl which also turns at the same speed as the yarn. The thread is first taken round the circumference of the pulley which is inclined at an angle to the axis of the bowl, on the circumference of which it is then laid in consequence of this inclination. Successive windings pressed by the underside of the pulley teeth depress the bowl axially to open a switch and stop the rotation when the yarn store reqd. is wound on.

Abstract: Printing screens are produced by placing a screen matl. of a thin, drawn thermoplastic polymer film (I) on a porous, ink-permeable substrate in close, face-to-face contact with the image side of an original and flash exposure for 10-4 to 10-3s with light rich in wavelengths of 0.8-1.2mum. (I) pref. consists of blow-moulded or biaxially oriented polyvinylidene chloride, PVC, polyvinyl acetate, polypropylene or polyethylene and stretched 2.5-6 times its original dimensions along both axes. (I) pref. is 5-12 mum thick. The light used has a wavelength of 0.7 mum or more and is not 60% in the 0.7-1.2mum range. An electronic flash tube, pref. filled with an inert gas, esp. Xe, is the prefd. light source. The screens are very sharp and free from irregular swelling or thickening, so that they give good copies. The matl. allows the use of re-usable electronic flash tubes, rather than disposable flash bulbs.

Title: Household water filter with dirt blowdown - and backflushing of filter obtained by double internal flushing valve
Inventor: BRAUKMANN BERNHARD W
IPC: B01D29/11
Filed: 1973-08-07
Abstract: A filter unit esp. for household water systems has a blowdown valve for periodic discharge of filtered solids. In the flow path upstream of the filter, two valves communicate at their outlet sides, one with one side of the filter, the other with the other side of the filter. One valve opens synchronously with the blowdown valve, the other alternates in its opening with the blowdown valve. Thus the valve arrangement permits backflushing, so that dirt is washed off the filter towards the blowdown valve.

Title: Combined pneumatic and hydraulic motor - has two liquid columns for alternate air feed, connected to orthogonal hydraulic cylinder
Inventor: OTTO THOMAS W
IPC: F01B29/00
Filed: 1973-08-13
Abstract: Combined pneumatic and hydraulic motor uses compressed air as the primary energy source, and has 2 mutually parallel cylindrical liq columns with one end connected to an orthogonal hydraulic cylinder through both ends of which extends a piston rod. Ducts connect compressed air to the other ends of the liq. columns. Float balls are in the columns between the air and the liq. and separate valves in the ducts between the compressed air source and the columns. Connectors between the piston rod and the separate valves together with the motion of the piston rod cause a reversal of the position of the valves, so that compressed air is let into one of the columns and blown out of the other, and this constantly reverses as the piston rod reciprocates. The air and liq. cannot mix.

Title: Shadow mask for colour TV tube with no local overheating - has soft iron base coated on both sides by copper or silver
Inventor: STUTH THEODOR DR
IPC: H01J29/07
Filed: 1974-05-02
Abstract: The shadow mask avoids overheating of the iron base material by using a metal with a good thermal conductivity wuch as copper or silver as a coating. The coating is applied on both sides of the iron, so as to cancel the effect of the difference in thermal conductivity of the two metals. This is done by a galvanic rolling process with an oxygen free copper. The base is a soft iron with a small percentage of carbon and manganese and a few traces of silicon and aluminium. The main part of the shadow mask is fixed to the screen glass pressing by a spring mechanism.

Title: Coal shearer machine tooling - has truncated cone endplate and vane with rim fitted pick holders
Inventor: BINGHAM TERENCE RONALD
IPC: E21C25/18
Filed: 1974-10-09
Abstract: Coal shearer winning machine tooling incorporates a tubular or drum shaped housing (1) having a helical vane (3) and an endplate at one end which is considerably larger in diameter than the housing. A radially outside part (3) of the endplate forms a truncated cone which slopes radially outwards as indicated from the housing. The vane or vanes and the endplate are fitted with pick-holders on their outer rims. Preferably the outside diameter of the endplate equals the total outside diameter of the vane. It is also possible to employ an endplate designed wholly as a truncated cone, with an angle between 3 deg. and 85 deg., more specifically 60 deg. The provision of a conical space clear of insertions or fittings between the outer rim of the endplate and the housing reduces initial contact with the coal and so reduces the dust make.

Title: Valve for large bore pipe lines - has two valve parts pressed apart against valve seats
Inventor: BECKER JOSEF
IPC: F16K3/18
Filed: 1974-10-22
Abstract: The valve housing consists of two parts, one part carries the inlet flange, the other the outlet flange. The two parts are bolted together, each part carries one valve seat. A valve body which consists of two discs, can be rotated so that the discs close-off the valve opening. A spreading arrangement incorporating a wedge piece is mounted between the two discs. In the closed position, each disc can be pressed against its own valve seat. The two discs each have a rim, the rim of one disc fits over the rim of the other disc, so that the two discs are centralised. Bolts mounted in the inner rim pass through holes in the outer rim and act as stops. These stops determine the max. and min. distance between the valve discs.

Title: Suspended monorail trolley for hospitals - has electric motor driven running gear also powering chain hoist gear
Inventor: GIESSLER HORST
IPC: A61G7/08
Filed: 1974-11-21
Abstract: The trolley has two sets of running gear, one driven by an electric motor and the other trailing, each comprising a yoke with a vertical running wheel and two horizontal guide rollers. The trolley frame has another electric motor geared to two chain and sprocket drives on each side. To each chain is coupled a vertical lifting rod which has at its lower end a finger-shaped hook for lifting beds and a flat-surfaced lug for lifting containers. After lowering the load, the hooks and lugs may be moved aside or rotated about the rod to keep them clear. Motion of the lifting rod support about the chain sprockets causes sideways retraction at the end of the vertical travel.
