Title: Injection plungers for pressure die-casting machines - using beryllium-copper sleeve on steel core
Inventor: KUNZ HUGO
IPC: B22D17/20
Filed: 1974-09-28
Abstract: Injection plunger for a pressure die casting machine, using an internal support passing through the plunger and contg. a blind axial hole for cooling; the end of the support is provided with a flange forming the front face of the plunger, and a tubular outer sleeve, pref. made of beryllium copper, butters against the flange. A tube carries coolant to the end of the blind hole, and it then flows back along an annular cavity. The length of the support from the flange to the rear part where a clamping sleeve is fixed is shorter than the max. length, but longer than the min. length, of the tubular outer sleeve which forms the outer dia. of the plunger. the composite plunger gives long life and when the outer Be-Cu is eventually worn, it can easily be replaced without the need to also replace its support.

Title: Polycarbonate film for insulation of dental prostheses - from plaster moulds used for shaping resin
Inventor: REHBERG HANS-JOACHIM PROF DR
IPC: A61K6/891
Filed: 1975-01-07
Abstract: Polycarbonate film of 0.002-0.01 mm. thickness is used as insulating film in prepn. of dental prostheses, e.g. between the plaster mould and the paste compsn. Used for making the dental plaste.

Title: Singly unsatd higher fatty alcohol prodn - by catalytic hydrogenation of higher fatty acid (esters) at high temp and press
Inventor: DEMMERING GUENTHER DIPL CHEM D
IPC: C07C33/025
Filed: 1975-03-26
Abstract: Continuous prodn. of singly unsatd., higher fatty alcohols by catalytic hydrogenation of unsatd. higher fatty acids, or their esters with lower monohydric alcohols pref. methanol, using 50-500 fold exces of hydrogen (w.r.t. the theoretically required quantity) at 250-350 degrees C under a press. >100 atm., in the presence of pieces of a zinc-contg. catalyst having a relatively low activity, is improved in that the hydrogenation is carried out without addn. of any lower alcohol as a diluent. Higher unsatd. alcohols (8-22C) are produced in high yields. The economy of the process is considerably improved by the exclusion of any alcoholic diluent (methanol was used in the conventional process) because of the redn. of the size of appts. and energy saving (there is no need to evaporate the diluent).
Patent DE-2515545-A1 (DE)
Title: Single and perfecting press - has asymmetric working cycle compensating for change from single to perfecting mode
Inventor: LEIN WERNER
IPC: B41F21/00
Filed: 1975-04-09
Abstract: To compensate for the change in relative timing of two sequential printing units when changing from the single to the perfecting mode, the engagement of the two printing cylinders is controlled by a shift register timed to produce an asymmetrical working cycle whereby the engagement of the second cylinder is delayed to allow for perfecting the largest intended sheet. Mechanically, the second cylinder (12) is engaged by a cam (16) whose follower is made operative by an output of the register during the idle part (a) of the cam contour, which part is long enough to allow the follower to be made operative during single or perfecting work.

The spring holds the arms outwards when the grab is lowered, its tension being overcome as the load is lifted.
Patent DE-2517346-A1 (DE)
Title: Photosensitive imaging array with main body divided into two - has exclusive OR gate deciding which of two signal lines connects to any element
Inventor: RAITH SIEGFRIED DIPL ING
IPC: H04N5/374
Filed: 1975-04-19
Abstract: The photosensitive imaging array avoids two disadvantages of existing arrays. The delay time of milliseconds needed for controlling the transparent structure is avoided and the problems related to coefficients in the Walsh image transformation are avoided. The main body of the receiver (E) is divided into two regions. All elements in one region are simultaneously connected over a control circuit to a common signal line. The control circuit alone decides to which of the two signal lines (A2) any given receive element is to be connected. This decision is taken by an exclusive-OR operation between the column and row control signals (Z,S).
Patent DE-2521418-A1 (DE)
Title: Low drag marine hull - with air and water pressure jets to form low resistance skin
Inventor: LEINBERGER KARL-FRIEDRICH
IPC: B63B1/32
Filed: 1975-05-14
Abstract: The marine hull is fitted with a pattern of jets (3, 5, 7, 9, 11, 13, 14, 17) above and below the waterline, and spaced around the hull. The jets above the waterline spray water at high pressure downwards along the sides of the hull so that when the water streams hit the waterline air is dragged down under the waterline to form a low drag skin. Further jets are positioned under the waterline to maintain and extend the skin. The main jets are at the bows so that the skin is dragged under the hull as the ship moves. Not only is the drag reduced by selective manipulation of the jets the ship can be steered, ie. by increasing the drag on one side. This provides an emergency steering to head the ship into the waves. The system is also suitable for fixed structures such as oil rigs.

Title: Vertical dipole radio antenna - has upper and lower conductors helically wound on insulating support tube when used for short wave operation
Inventor: GURR JOHN HENRY
IPC: H01Q9/18
Filed: 1975-10-16
Abstract: The vertical dipole antenna is suitable for both commercial and amateur radio operation. It has a feed line extending orthogonally inside a tubular metal sleeve. The line upper end carries a protruding upper conductor of quarter wave-length. The upper end of the metal sleeve carries a lower conductor of the same wavelength on its outer side. When used for short wave operation the upper (8) and the lower conductor (6) of the antenna are helically wound on an insulating support tube (1, 2) preferably of fibreglass. The two conductors may be separated by several such support tubes, firmly interconnected. Typically the two conductors are of split shaped.

Title: Bathing pool water circulation system - has set of supply ducts on bottom directing water upwards in sloping jets
Inventor: KAISER ULRICH ING GRAD
IPC: A63B69/12
Filed: 1976-01-20
Abstract: The bathing-pool installation provides constant circulation of the water in a circuit containing a filter assembly and a basin, fresh water being supplied to the basin mainly, or entirely, by supply ducts on the bottom. Waste water is carried away in the surface area, esp. via an overflow gutter. The supply units (24) on the pool bottom (12,14) are set out in such a way that fresh water from them emerges as a jet inclined upwards. Each of them may be fitted with a joint pipe socket (10) with a grating cover (20), with lamellar ducting elements (24) to generate a jet sloping upwards; these elements may be adjustable. The cover may be symmetrically arranged in a frame cutout in the bottom, so that it can be set invarying positions. The formation of dead zones is largely prevented, with continuous circulation evenly distributed all over the pool.

Title: Flame deseaming machine fitted on driven trolley - with driver's cab using plastic window not obscured by hot spray
Inventor: MUENCH GERHARD
IPC: B23K7/06
Filed: 1976-02-10
Abstract: Plant for flame deseaming of a workpiece comprises usinga driven trolley fitted with a jib, extending over the workpiece, and carrying at least one burner set; a deriver's cab is also proided on the trolley and fitted with one or more windows. Novelty is that at least the window facing the burner(s) is fitted with a pane of Plexiglass (RTM). The pane pref. has a thickness of 5-12 mm, esp. 10mm. The pane is designed to replace both a pane of heat-resistant glass and also the wire mesh screen previously employed in front of the glass. The transparent plastic pane has a much longer working life than the glass pane and mesh screen. Normally, the flying spray of slag etc. created by the burner obscures the screen and damages the glass; and the screen reduces visibility even before it becomes coated with slag. The plastic pane remains clear and lasts several months.
