Title: Seal for high pressure hydraulic valves - has O-rings compressed between annular distance pieces to expand seal radially
Inventor: ROSTECK FRIEDRICH WILHELM
IPC: F16J13/12
Filed: 1976-03-06
Abstract: The end plug (1) which screws into a housing is provided with a threaded end (3) and two sections of different diameters (11, 5) joined by a shoulder (4). On O-ring (6) which fits over the diameter (5) is secured by an annular distance piece (13) and a retaining ring (8). When the plug is fully tightened the distance piece (13) abuts against the shoulder (12) in the housing and the O-ring is compressed against the plug shoulder (11). This axial compression causes the O-ring to expand radially and form a seal with the bore (10). This method of sealing avoids the use of grooves with sharp edges which could damage the O-rings during assembly.

Title: Film splicing keeping synchronous sound track - by transferring removed sound track to following spliced film section and maintaining eighteen frame sound advance
Inventor: MOSHAGE GUENTER
IPC: G03B31/02
Filed: 1976-06-25
Abstract: The recording lies on the sound track 18 frames ahead of the corresponding picture. Thus, when a section is cut out of the film and the gap closed, the sound recorded opposite the last 18 frames of the piece removed must be copied on to the piece retained. This is done by passing both lengths of film synchronously and simultaneously through a sound-reproducing and a sound-recording head respectively. A third length of sound track can be used as intermediary.

Title: Reciprocating pump with no crank - has hollow piston element driven by eccentric disc rotated by internal planetary gearing
Inventor: BROX DIETER
IPC: F04B5/02
Filed: 1976-06-26
Abstract: The pump drive system is for pumps handling liquids or gases or producing a vacuum, and produces reciprocating movement of the piston element without the need for a crank housing. This is achieved by driving the sliding hollow piston element by means of a rotating eccentric disc inside this element. The disc has internal gear teeth engaged by planetary gear wheels driven by the pump shaft. Valving is provided by spring biassed ball valves in the inlet and outlet ports. The eccentric movement of the drive is converted to reciprocate by use of idler planetary gears.

Title: Sepg. socks knitted as a continuous strand - by atomising heat sensitive connecting thread detected photo electrically
Inventor: GHEYSSENS M FRITZ
IPC: D04B19/00
Filed: 1976-08-20
Abstract: Socks are knitted in a continuous strand on a circular machine. The socks moving down from the knitting zone to a zone of the machine beneath are joined together by threads which collapse when exposed to heat. This joining zone of the socks, is pulverised by a medium raised to a temp. at which the joining threads disintegrate, during the descending motion as the socks leave the knitting zone. A photoelectrical device is used to detect the position of the connecting zone between the toe of one sock and the welt of the next and to initiate the pulverising action. At the commencement of the passage of the strand through the station where sepn. takes place, a downwards tension is applied to the sock by jets of compressed air which widens the joint so that reflectors provided to assist the working can direct the rays to the light sensitive element. System prevents any damage to the sock by a sepg. mechanism, and saves the extra operations necessary to remove the remnants of the joining thread.

Title: Drawn, temporarily meta-stable, laminated thermoplastics, shrink film - prepd. by combining profiled film, flat intermediate film and shrink film into a laminate with air pockets
Inventor: KAWASAKI TETSUO
IPC: B65D65/40
Filed: 1976-09-09
Abstract: Mfr. of a 3-ply, shrink film laminate suitable for packaging impact-sensitive merchandise comprises combining a shrink film with another film lamina to define air cushions, in such a way that, simultaneous with the application of a covering film lamina, the 2 three-plies are bonded together by rollers. A shaping roller under vacuum is used for mfr. of the air cushion film. Plastics are melted and extruded through a nozzle to form a film, on the shaping roller. The vacuum causes the film to closely hug the configuration of the roller surface. Similarly, the melt is extruded from the nozzle to form a second film which is combined, in flat film shape, with the profiled film on the roller. This combination is facilitated by a resiliently supported pressure roller at the point of contact of the two laminae. A pre-stressed shrink film, mfd. in known manner, is hauled off another roller and conveyed, in cold state, to the pressure roller and laminated, without shrinking, to the covering film, at still at 150 degrees C hot. The resulting 3-ply laminate is then hauled off the shaping roller. Polystyrene, polyethylene etc. are suitable plastics, for this process.

Title: Ethylbenzene purificn. to remove organic aluminium impurities - by treating with steam, esp. after ammonia treatment, giving easily filtered ppte.
Inventor: HEIMLICH GUENTHER DIPL CHEM DR
IPC: C07C7/00
Filed: 1976-12-31
Abstract: Purification of ethylbenzene (I) prepd. by reacting benzene and ethylene in presence of an AlCl3 catalyst, comprises first phase sepn. of most of the heavier organic Al cpds. from lighter crude (I). This is then treated with steam using an amt. at least equiv. to the amt. of residual organic Al cpd. The resulting Al-contg. ppte. is separated and the Al-free (I) distilled conventionally. Opt. the crude (I) is treated with NH3 before steam treatment and esp. enough superheated steam is used so that directly after treatment traces of water (but 500ppm) are present in (I). (I) is used to make styrene. Treatment with steam gives a ppte which is easily sedimented (contrast use of NH3 alone which gives a voluminous ppte) and there is no need for water-washing of crude (I), so no polluting waste streams are generated.

Title: Spherical plastics and reinforced concrete oil tank construction - involves initially heating concrete outside mould space, and intervening space formation
Inventor: KESTING LORENZ
IPC: E04H7/18
Filed: 1977-02-15
Abstract: The process for erecting a spherical container, esp. a heating-oil tank with a prefabricated thermoplastics inside container, pref. made of plastic and reinforced concrete, involves introducing concrete into a moulding space between this container and sheathing, to made a seamless concrete sheet round the inside container. The concrete is heated outside the space and poured in a hot condition. When it has cooled and hardened an intervening space (3) is made between the concrete shell (2) and inside container (4). The concrete is pref. heated to 48 deg.C, and introduced into the space at approx. 43-44 deg.C. It may be steam-heated outside the space. This facilitates preparation of an adequate intervening space, with a seamless concrete sheath and no auxiliary media.
