Patent DE-2413486-A1 (DE)
Title: Bark removal system for tree trunks - has five adjustable milling cutters and size sensing and adjusting rollers
Inventor: KRONSEDER JOSEF
IPC: B27L1/10
Filed: 1974-03-20
Abstract: The bark remover has five milling cutters driven by flexible drives from a gearbox driven by V-belt pulleys from the lower take off of a tractor. One cutter is in a horizontal position and fixed whilst the next cutter pair are displaced by some 20-130 deg. and the last cutters are vertically disposed. Spring tension keeps the last two cutters in contact with the trunk being debarked. The second cutters are maintained in contact with the trunk by slotted jaws and shackles. Two conical rollers reduce the trunk size and activate the jaws and shackles accordingly to ensure contact of the cutters. Transport rollers aid the passage of the trunk through the cutters.

Title: Plastics sheet continuously welded by electrically heated wire - pressing into sheet as it rolls around insulated wheel
Inventor: HINTERSEER HEINZ
IPC: B29C65/18
Filed: 1974-05-14
Abstract: A seal welding appts. for continuously joining (or sealing and cutting) thermoplastics or partly thermoplastics strip comprises an endless, electrically heated bright wire, or round, flat, oval, or polygonal section, which is tensioned and applied to the sheets as they run around a portion only of the circumference of a revolving wheel; the face of the wheel is electrically and thermally insulated and the operation takes place without slip, the wheel, sheets and wire-all moving at the same angular speed. The wire is itself pref. the electrical conductor, with a relatively short hot length between contact pulleys and a longer, higher-resistance length tensioned by an adjustable jockey wheel. Heating of the wire occurs only in the contact zone, the cooling run of the sheet being relatively long; this permits welding temps. only slightly above the fusion temp. of the sheet to be used, with a high welding speed.

Title: Burner head for flame-cutting machine - where eight burners are mounted on a rotary turret for rapid burner selection
Inventor: ETTER BERWYN ELMER
IPC: F23D14/42
Filed: 1974-06-14
Abstract: Cutting head for a flame-cutting machine has a rotary burner holder located above the workpiece on a carrier arm. The burner holder consists of a turret revolving on a horizontal axis and is provided with several burner mountings, each of which has gas channels and a screw-thread for making a gas-tight joint with a burner. Spring-loaded balls with matching holes are pref. used for indexing each burner in its working position, i.e. during the stepwise rotation of the turret which contains several pairs of gas channels mating with a pair of channels in the carrier arm. Due to the large number (e.g. eight) of burner nozzles on the burner head, the flame-cutting machine is very versatile and non-productive time reduced to a minimum.

Title: Sheet printer for automatic optical reading - has matrix printer connected by control and supply cable to keyboard
Inventor: SCHLOBIES CHRISTOPH DIPL PHYS
IPC: B41J3/28
Filed: 1974-06-25
Abstract: The matrix printer is contained within a housing (1) and has an ink ribbon (5) passing in front of it between two spools (6). Alternatively fibre ball point-pens can be employed in place of the ink ribbon. The housing can be precisely located over the sheet to be printed by attaching it to a carriage or slide which moves to and fro across the sheet on a rail. This rail can be moved up and down on two further rails located either side of the sheet which is typically rested in a frame. The keyboard can be mounted directly on the housing whereby five keys are provided for single base operation thereby allowing all required symbols to be selected with the use of a 5-bit code.

Title: Ink jet printer with contuously rotating symbol stencil - has one ink jet nozzle for each printing position along line
Inventor: WIEDEMER MANFRED
IPC: B41J2/135
Filed: 1974-08-30
Abstract: The stencil (7) incorporating openings (8) corresponding to the symbols to be printed, rotates in the direction of the printed line. A control unit (4) comprising e.g. an electromechanical system or a compressed air jet, can stop the ink stream, which is delivered from the nozzle (1), in an upper (6) or a lower rest position (5) so long as the required symbol opening is not in front of the relevant printing, when the symbol opening is correctly located. In the case of movable nozzles an electromechanical control unit is used. If a fixed nozzle is employed, however, compressed air jets serve as the control medium.

Title: Table cigarette lighter with petrol vapour cavities - rendered safe on principle of Davy's safety lamp
Inventor: DUFFNER KONRAD
IPC: F23Q2/36
Filed: 1974-12-07
Abstract: The working parts of the lighter (13) occupy only part of the case, leaving sizeable cavities (18, 19) through which air is admitted (via 10) to support and steady the burning of the lighter's flame. When the lighter is filled, any slight spillage leads to the presence of fuel vapour in the cavities and so to an uncomfortably large, if not actually dangerous, flame at the next ignition, unless this is deferred for some minutes. To avoid this, the cavities are lined wholly or partly with metal (or metal covered) gauze, localising and confining any combustion in the manner of Davy's safety lamp.

Title: Inductive preheating of wire or strip welding electrodes - before immersion in melting bath or before arc ignition
Inventor: GERDAU HERBERT
IPC: B23K9/235
Filed: 1975-10-08
Abstract: Wire- or strip electrodes are inductively heated before immersion in melting bath or before ignition of arc. After passing through weld current contact, the electrodes are passed through an induction circuit. Preheating achieved can be varied and can be brought to 1000 degrees C, according to welding process and alloy compsn. Inductive preheating of currentless wire- or strip electrodes takes place directly (30-50 mm) before immersion in melting bath. Heating method can be applied to electrodes of all profiles and dia., for welding processes including metal active-, MIG, TIG, submerged arc-, electroslag and filler wire welding, opt. under a protective gas. Inductive preheating of filler wire electrodes helps to achieve an additional drying of the often hygroscopic flux fillings. Fusing efficiency is not reduced. Burning down of alloying elements is reduced, and degradation of alloying elements, by dilution with substrate material is prevented.

Title: Variable height suspension for quarry vehicle - with vertical ram through yoke pivot on each wheel to lower stabilising posts
Inventor: ALBERTINI WILLI
IPC: B60P3/40
Filed: 1975-12-05
Abstract: The quarry vehicle has a low slung chassis with the wheels on outriggers on each corner. The wheels are pivotted about vertical posts (13) with upper and lower bearings (12). The posts are raised and lowered hydraulically using an internal ram system (14). This alters the ground clearance of the vehicle so that it can negotiate low galleries.

Title: Water softening plant - using water jet ejector for regenerating agent suction through ion exchangers
Inventor: DULGER VIKTOR
IPC: B01J49/75
Filed: 1976-03-17
Abstract: In a water treatment plant, complete softening of pressurized water is achieved by ion exchangers and a pump which can pump regenerating agents through the ion exchangers. This pump is a water jet ejector which is operated by the pressurized water and is connected with its suction to the regenerating agent outlets of a cation exchanger and of an anion exchanger. Design saves a special electric motor for the pump. The mixing with the ejector drive water dilutes the agent to a harmless concn. which can be safely discharged into the drainage system.
