Title: Oil burner unit for road material drying kilns - uses several atomisers with total capacity matching max. heat requirement
Inventor: BENNINGHOVEN ERICH
IPC: F23D11/24
Filed: 1977-03-14
Abstract: The oil burner unit for road surfacing material drying kilns uses several atomisers (20) in line or grouped around a central one, whose combined maximum output corresponds to the maximum heat requirements of the kiln. The atomisers are in the outlet end of a tubular casing (2), behind a flame stabiliser (21). Further upstream the casing houses a motor driven axial blower (5) with variable blade angle and in the inlet pivoted (10, 11) flaps (8, 9). The position of the flaps is linked mechanically by toothed segments (12, 13) and a drive mechanism (14, 16) to that of an oil input controller (18), both being operated by a servo-motor (17).

Title: Securing ring for flange connections - has rod with grooves machined at regular intervals to increase flexibility
Inventor: SUNDHOLM GOERAN
IPC: F16L23/024
Filed: 1977-04-29
Abstract: The securing ring is used for mounting a flange, which is split in two parts in a radial plane, over the outside dia. of a pipe. The ring lies in an annular groove of semi-circular section in the outside of the pipe, while the two flange parts are mounted either side of the ring. The inner edges of the flanges are shaped to fit against the ring which is of circular section. The ring is made from a length of rod or wire and is made by machining deep grooves at regular intervals in the wire to make it more flexible. When the grooves have been machined, the wire consists of cylindrical sections (1), which are interconnected by short thin sections (2). This wire is bent round into the shape of a ring.

Title: Pipeline cleaning fluid injector - has reciprocating tube injecting measured quantities, acting with ball valve in branch line
IPC: F16L27/12
Filed: 1977-07-04
Abstract: The injector for introducing regulated quantities of liquid at intervals into a pipeline or container (6) for e.g. cleaning purposes, has a tube (20) passing through a sleeve (10) so that it can be recirprocated. An attachment at the end enables it to be connected to a pump or other liquid supply. Sloping at an acute angle to the sleeve is a branch (14) with a ball (16) inside, acting as a valve member. This ball is forced inwards by a spring (26) behind it, and when the tube (20) is drawn back to a point beyond the branch connection, the ball is forced forwards by the spring (26) to enter a cavity (16) inside the sleeve (10) to act as a valve member, this being the closed position. The outer end of the tube (20) is guided by a nuff (22) which screws onto the end of the sleeve (10).

Title: Meat band saw - with plastic foam blade cleaning blocks and plastic scraper lips
Inventor: BUTZ ALOIS
IPC: B23Q11/02
Filed: 1978-01-23
Abstract: A meat bandsaw for butchers is kept clean by a block of plastic foam which has been cut parallel to the saw blade and is pressed with the cut surface against the sides of the saw blade. This removes not only bond splinters and coarse particles but also the film of smudge which is caused by the gat content of the meat and would build up as it is not removed by ordinary scrapers. Specifically the saw blade passes after a first scraper unit with revolving brushes through a second scraper unit with plastic foam inserts. A pref. material is compressible polyurethane foam. Two additional scraper lips with upturned edges contact the saw blade on a bracket with elongated holes. A tray collects the scrapings from the saw blade.

Title: Raschel lace machine thread guide - has a rod with flattened end to carry a thread guide hole
Inventor: NANNINI GIANCARLO
IPC: D04B27/02
Filed: 1978-02-11
Abstract: The thread guide for a lace machine has a long body for connection to the machine drive at one end, and to carry a rod section at the other end. The end of the rod is flattened and carries two adjacent axially parallel holes with a thread passing through each. Designed partic. for Raschel lace machines, the unit takes up little room and can work with heavier threads to build up a stronger lace effect. The parts are all of conventional shape and materials, so that costs are relatively low.
Patent DE-2806949-A1 (DE)
Title: Weatherproof oil-and abrasion-resistant, flexible power cable - for outdoor use, has conductor(s) encased in PVC mantle(s) coated with thin polyurethane
Inventor: ENGEL DIETER
IPC: H01B7/28
Filed: 1978-02-18
Abstract: Plastics-insulated, single- or multi-core electric line has a thermoplastics tubular mantle surrounding the core(s). The mantle is provided with a thin polyurethane coating, but itself consists of PVC. The line is suitable for outdoor applications e.g. with lawn-mowers, is flame- and oil-resistant, flexible even at relatively low temps. and has good abrasion-resistance. Its mfr. is less expensive than similar prods. where polychloroprene is used. The polyurethane coating makes up for the shortcomings of the PVC in comparison with the polychloroprene.
Patent DE-2806975-A1 (DE)
Title: Multi stage press ram balancing arrangement - uses weight operated by lever connected to extension of ram
Inventor: DRKAL JAN DIPL ING
IPC: B30B15/00
Filed: 1978-02-18
Abstract: The balancing arrangement for the ram of a multi-stage press, includes a weight in the shape of a piston (7) connected by a double two-armed lever (14) to an extension (3) of the ram (2). The balance weight is the piston of a single acting pneumatic cylinder (8). The ratio of the mass of the piston to the mass of the ram is inversely proportional to the lengths of the arms of the lever. A cover (9) over the pneumatic cylinder forms an air cushion which loads the piston so that play in the transmission mechanism is taken up. The cover can be interchanged to change the loading.
Patent DE-2807766-A1 (DE)
Title: Splitting hammer for line transporting opened pig carcasses - has easily manipulated axe blade with spike as guide
IPC: A22B5/20
Filed: 1978-02-23
Abstract: The carcases of slaughtered pigs are split lengthways into sides by an axe with a cutting edge and a section provided with a handle. The axe with its roughly horizontally-aligned cutting edge is arranged below the barrel of a hammer cylinder fed for pref. by a compressed air line. A handle is provided with a trigger and the hammer may be supported by a counterweight and a cable on pulleys above the conveyor. Manipulating levers extend near enough horizontally and parallel to the cutting edge of the axe. Method overcomes the problem that the ideal method of splitting the sides of the carcase accurately, is either wage intensive or required highly expensive plant. The cheaper method of the splitting saw reduces the quality of the product.

Title: Three-shank stray field transformer - has core laminations of ferromagnetic sheet metal with high specific iron loss compared with yoke laminations
IPC: H01F38/08
Filed: 1978-04-06
Abstract: The transformer has an E-shaped magnetic laminated core and a yoke connecting the free shank ends. The E laminations (2) consist of ferromagnetic material with a higher specific iron loss than the material of the yoke laminations and/or the stray field laminations (S) between the primary (W1) and secondary (W2).

Title: Surf-board composed of hard-foam, cavitied core - over which two plastics half-shells are glued, fitted with valve and manometer to check for leakages
Inventor: HUESS OTTO
IPC: B63B35/79
Filed: 1978-07-04
Abstract: Mfr. of surf board comprises placing a pre-shaped, ready-made, core into 2 similar half-shells adhesively bonded to them.
