Patent DE-2545076-A1 (DE)
Title: Arc welding electrode rod or brazing rod - heated and fed through hot flux to obtain adherent sintered flux coating
Inventor: GERDAU HERBERT
IPC: B23K35/40
Filed: 1975-10-08
Abstract: Electrode rods for arc welding, and hard solder rods for brazing, are coated with flux via induction heating. The rods, esp. the brazing rods, are fed continuously through an induction heating coil; and the hot rods then travel directly through a metal tube contg. powdered flux, which is also induction heated by a coil round the metal tube. The hot flux is at a temp. to suit the flux compsn. and sinters onto the hot rods to form an adherent coating. Rod electrodes, which have already been coated by a conventional method with a hygroscopic flux, or with a flux for underwater welding, are pref. treated in a similar manner to obtain a moisture-proof coating. The thickness of the coating is easily controlled; and the drying process, which is necessary when the conventional method of press coating is used, can be eliminated.

Patent DE-2552549-A1 (DE)
Title: Feeding delicate flexible material in lengths for cutting - on shear with lifting worktable and adjustable drawing mechanism
Inventor: NUENDEL ULRICH
IPC: B26D1/04
Filed: 1975-11-22
Abstract: Synthetic foam, in the form of a continuous hands and similar flexible materials from a reel, is drawn by mechanical means through the gap between the upper moving knife a and the fixed knife on the worktable, from the side of the shear farthest from the reel, to the length required for cutting. This ensures that uniform lengths of delicate material can be cut off accurately and consistently. The worktable positioned behind the knife can be lifted so that the material is raised clear of the lower knife, leaving plenty of room for the clamp to grip the material edge.

Title: Rotary grill with foil tube food holder - allows quick even cooking with no leakage of food juices
Inventor: MUELLER PETER
IPC: A47J37/04
Filed: 1975-12-10
Abstract: The rotary grill includes a food container with a foil tube (23) which is sealingly closed at both ends but has a hole (25) at one end to let out the steam pressure. The two end sections of the tube are each held by a holder (16) which are each supported on the associated rotating part (13,14) by means of which the tube is rotatably held in the grill chamber. There is sufficient room between the end of the foil tube and the food to collect up the juices from the food so that they do not flow out through the hole (25). The two holders ensure that the two end sections of the tube are held in the region of the centre axis and that the tube itself is held taut so that the food lying loose in the tube does not form an imbalance for the rotating parts.

Title: Flat knitting machine with beedles controlled by pressure bars - attached to tripping plates locked by patterning system
Inventor: KRAUSE ERICH
IPC: D04B15/70
Filed: 1975-04-08
Abstract: In a flat knitting machines, the selection of the needles is effected by sinking or raising the needle or a detail controlling it, into or out of the needle bed, so that the foot of the needle or the foot of the jack projects fully or partly from the bed or retracts into it, and as selected is acted on by cams. The needle or jack foot is lifted by a spring and is depressed partly or fully into the bed by presser bars, arranged in rows, so that they can be switched into and out of action, on a carriage on which the cams are assembled. Each groove in the needle bed has an auxiliary selector detail which can be displaced into any one of a series of positions aligned to the separate presser bars, whilst each presser bar is attached to a tripping plate. This has a locking nose which engages with a stop so as to hold the tripping plate in a selected position. A stop bar is allocated to each tripping plate to which the stop is secured. Each stop bar has also a further stop which contacts a stop bolt controlled by electromagnets. Has a particularly compact arrangement of the presser bars. An edge can be knitted in 1:1 or 2:1 without altering any detail in the needle bed whatever, whilst, by providing the intermediate jacks with more than two fixed feet an edge in any other combination can be knitted.

Patent DE-2618805-A1 (DE)
Inventor: SIGWART FRITZ
IPC: E04B5/26
Filed: 1976-04-29
Abstract: In known wall elements, it has proved disadvantageous that they are not stable enough in order to be able to be fitted in a self-supporting manner - for example, as intermediate walls. As a result, a novel structural element is to be provided which may be used in any manner as an intermediate wall or floor part, as well as a load-bearing element for window sills, door thresholds or the like.   For this purpose, a foam core (10) is accommodated in a box-like casing (9) which is at least U-shaped in cross-section and consists of a wood-like solid material, and reinforcing inserts (11, 12, 13) are embedded in said foam core. In this arrangement, the reinforcing inserts (11, 12, 13) are to be embedded in rigid foam, in particular in a casing (9) consisting of mineral bound wood wool. <IMAGE>

Title: Assembly conveyor for tape cassettes - has stops raised and lowered hydraulically to control assembly templates at work positions
Inventor: MATSUDA HIRONOBU
IPC: B23Q7/14
Filed: 1976-09-25
Abstract: A belt conveyor designed for assembling tape cassettes, uses templates to hold the cassette bodies as they pass through successive work positions where components are added, screws inserted, tests are made etc. until the cassettes are unloaded. At the cassette loading stage, a system of stops is operated to halt the cassette at a given position. These stops are raised and lowered by hydraulic piston and cylinder actuators, underneath. At certain working positions, pairs of stops (69) mounted on wheeled carriages (70) are raised from underneath to lift up the template (24). A hydraulic actuator alongside the conveyor pushed a wedge shaped plate (73) sideways so as to lift the wheeled carriage.

Title: Equipment synchronising sound tape recording to narrow gauge film - includes continuously variable tape speed adjuster and adjuster for tape length between sound coupler and tape recorder
Inventor: WITTKE WOLFGANG
IPC: G11B15/44
Filed: 1976-12-14
Abstract: The tape speed adjuster, which is intended for the provision of lip-cynrhonised sound to a narrow gauge film, consists of a cone selectively movable along the shaft of the drive motor. Cylindrical regiosn along the cone correspond to the standard tape speeds. Drive is transferred from the cone to a flywheel by an idler wheel. If a sound coupler or the pilot tone process is being used synchronising errors during film projection due to tape dimensional changes can be corrected by altering the spacing between three rollers over which the tape passes and which are positioned between the tape recorder and the sound coupler. The patent describes an arrangement for marking the tape to show start and end of filming a microphone holder attachable to a portable tape recorder and a sound-proof case for a camera.

Title: Coin operated lockable storage cabinet for skis - only encloses ski bindings and sticks and has skis projecting at top and bottom
Inventor: SCHNELL GEORG
IPC: A63C11/02
Filed: 1977-02-15
Abstract: A lockable cabinet (4) for storing skis in public places, has a coin operated lock (6, 7) located in the door (5). The oblong vertical cabinet (4) has a length which will fully accommodate ski stick, but not skis. The skis are therefore able to protrude through slots (21) in the top and bottom panel of the cabinet. Two parallel lugs, fixed to the inside of the rear wall are provided to locate the pairs of skis by means of the bindings. Since the slots (21) are only wide enough for the thickness of two skid (16), they give no access to the inside of the cabinet and its content is thus secure from theft.

Title: Cigarette making machine buffer conveyor system - has two different level vertical shafts between horizontal belt conveyors forming alternative paths
Inventor: TOLASCH GERHARD DR ING
IPC: A24C5/35
Filed: 1977-05-13
Abstract: The cigarette handling system for cigarette making machines, as in the main patent, uses a series of belt conveyors between which the cigarettes are conveyed. The cigarettes can be conveyed in different directions towards or away from a buffer store, depending on the capacity of the machines. Several alternative paths are formed. An upper horizontal section (512) is fed vertically from below through a channel (511) formed by verticals between two horizontal conveyors (513, 514). This is in turn supplied from another lower level horizontal section (519) with a second vertical channel (518). The bottom of this channel terminates above two horizontal conveyors (522, 523) which have their top strands moving towards each other to a chute (525) below.
