Patent DE-2727715-A1 (DE)
Title: Screw for expanded wall socket - has thread on screw extended up shank to allow screwing completely home
Inventor: FISCHER ARTUR DR
IPC: F16B13/02
Filed: 1977-06-21
Abstract: The expanding screw socket has two axial slots and a lengthwise bore smaller than the core dia. of the screw to be accommodated. The external dia. of the screw is roughly the same as that of the socket. The thread (4) on the screw (2) extends right to the screw head (3). This allows the screw to be screwed right home in order to clamp the item to be secured firmly against the wall.

Title: Induction hardening plant suitable for crankshafts - with inexpensive cooling water system for electrical appts. and quenchant
Inventor: REINKE FRIEDHELM DR ING
IPC: C21D1/42
Filed: 1977-07-06
Abstract: The plant has electrical components which are cooled by water (a); and also a liq. quenchant (b) for hardening the heated workpieces. Both liqs. (a, b) travel in separate closed circuits, each of which contain cooling appts. (a1, b1). The cooling appts. (a1, b1) is connected in series and fed with cold water from a mains water supply so the cold water is used to cool water (a) before cooling liq. (b). The two cooling units (a1, b1) are pref. each located in a tank (a, b); and the cold water leaving units (a1) is pref. collected in a tank (c) before being fed through unit (b1). Cooling water forms a substantial part of the cost incurred with induction heating and hardening plants. The invention reduces the water costs by ca. 50%.
Patent DE-2732351-A1 (DE)
Title: Polyurethane flanged edge strip moulded on table-tennis table top - to seal them off against weather, preventing rotting and/or warping
IPC: A47B25/00
Filed: 1977-07-18
Abstract: Parent patent described a weather-resistant table top for pingpong table having seamless, moulded-on edging strip of polyurethane. In this addn. the edging strip is substantially deeper than the table top is thick, thus protruding downwards beyond the thickness of the same. The edging has a flange along its lower edge which bears against the underside of the table top. The polyurethane edging strip as claimed, fully protects the marginal zones of the table top against degradative action of weather, e.g. rotting or warping. This enables the table top to be mfd. from plywood or chipboard or similar material instead of considerably more expensive glass-fibre-reinforced plastics sheets.
Patent DE-2734526-A1 (DE)
Title: Continuous wrapping machine using plastics strip - has longitudinal and transverse sealing units and two separately driven plates sliding on strips near item guide trough
Inventor: BECK OTTO DIPL ING
IPC: B65B9/06
Filed: 1977-07-30
Abstract: The continuous wrapping machine shapes longitudinally seals a horizontal hose from a strip of packing material. A horizontal guide trough for the items to be wrapped precedes the hose-shaping mechanism, and a plate slides in and out of it. The lengthwise sealing unit is followed by a transverse sealing unit with parting mechanism gripping the hose between the items. Two plates (9, 10) slide on strips in line and form hysteresis loops, being actuated by separate drive and guide mechanisms to work hand over hand near the guideL trough (2).
Patent DE-2741052-A1 (DE)
Title: Diagnostic X=ray tube with TV camera and film camera - has circuit to monitor X=ray tube voltage to avoid needing test button
Inventor: BRUNN KLAUS DIPL ING
IPC: H05G1/38
Filed: 1977-09-12
Abstract: The diagnostic X-ray tube/tv camera/film camera system has a comparator (16) comparing the X-ray tube voltage with a signal representing the set exposure variables. The comparator output operates an indicator (15) when the different between its input signals exceeds a given amount. The advantage lies in avoiding the need for a test button to check whether during a filmed scene the control circuitry for the light integral per exposure is correct.

Title: TV camera optical system for observation of welding arc - has graded filter which attenuates light from arc but not from hot metal and polarisers reduce overall intensity
Inventor: ITO YOSHITOSHI
IPC: G02B5/00
Filed: 1978-01-13
Abstract: An optical system is used for observation of an object having an area of intense brightness. It is used esp. in a TV system for the observation of a welding operation, and there is a system to attenuate the light to protect the TV camera. The light from the arc (22) passes a pinhole (24) and is split into two beams; it then reaches a filter (25) with non-uniform absorption so that the light from the arc (22) is more attenuated than that from another part of the object, such as the hot welded seam (23). The light then passes polarisers (30, 31) and an objective lens (26) to be imaged on the photosensitive surface in the camera (27). The overall control of light intensity is effected by the polarisers.

Title: Automatic control of charge height on sintering belt - via row of pneumatic sensors controlling flow of sinter mixt. onto belt
Inventor: SAUER BALDUR ING GRAD
IPC: C22B1/20
Filed: 1978-03-31
Abstract: The sintering mixt. flows down a hopper fitted on its bottom end with a loading drum (a) driven at an adjustable r.p.m. Drum (a) drives the mixt. through a slot, the width of the slot being controlled by an adjustable shutter (b); and the mixt. is then distributed via a baffle plate across the sintering belt. Above the belt is a pneumatic sensor (c) of conventional type, which measures the height of the sinter mixt. on the belt and adjusts the speed of drum (a) and the height of shutter (b) so a constant sinter height is obtd. on the belt. A row of sensors (c) is pref. located transversely across the belt. The appts. is not affected by the dirt and heat which prevent other, conventional processes and devices from being reliable.

Title: Metal bar pickling plant - with chain catenary loops in vats keeping bars in motion
Inventor: TSUKAMOTO KOTARO
IPC: C23G3/00
Filed: 1978-04-11
Abstract: A pickling plant for metal bars consists of acid-filled rectangular vats, with a motor driven shaft horizontally arranged above one of the long sides. Each shaft carries several (five) sprockets for a chain, one end of which is fixed to the rim of the other long side while the other end is fixed to the sprocket. Moving the sprocket keeps the bars in motion so that they are pickled uniformly on all sides and in a much shorter time than with the conventional system in which a bundle of bars is lowered from a crane in the vat.

Title: Cutting machine for packaging paper - is computer controlled to ensure constant length between cuts
Inventor: MOHR KARL
IPC: B26D7/01
Filed: 1978-05-26
Abstract: When cutting sheets of paper or cardboard for use in packaging machine it is important that there is no cumulative error in the line of cut in order to ensure the correct subsequent folding of the sheets. To achieve this result the cutting machine feeds the stack of sheets (11) to the blade (11) by a screw driven slide (7). An indicator (4) on the slide (7) passes over a notched scale (2) and generates pulses in a control element. These pulses are transmitted to a computer (6) which compares their number generated between successive cuts with the required number and adjusts the control mechanism accordingly.
Patent DE-2825428-A1 (DE)
Title: Atomiser pump for adhesive materials - has coaxial spring-loaded piston in stepped cylinder for self-draining into container when in rest position
IPC: B05B11/00
Filed: 1978-06-09
Abstract: The atomiser pump has a co-axial pair of pistons of different dia. in a common stepped cylinder. The inlet is in the smaller-dia. cylinder. The two pistons are held together by a single spring so that they move together when actuated. The outlet valve is formed at the point of contact between the two pistons and the larger-dia. piston carries the atomiser head. In the rest position of the pump the internal pump chambers are connected with the container on which the pump is fitted so that the chambers empty under gravity, thus preventing undesirable interaction between any pump components and the liq.

Title: Seven segment display device for figures - with light from bulb applied to light conductors which illuminate corresponding segments
Inventor: ANGST WALTER DIPL ING
IPC: G09F9/305
Filed: 1978-11-17
Abstract: Light is applied to light conductors through transparent areas of a movable coded control diaphragm. Their outlet ends illuminate the seven segments in accordance with the position of the diaphragm. Light conductors are flat and stacked on top of each other. The light enters through a narrow side and emerges in the position and shape of the segment to be displayed.
