Title: Conical warning sign laying in series on road - involves lower and upper retainers alternately opening and closing to drop stacked signs
Inventor: RITAMAEKI RISTO
IPC: E01F9/70
Filed: 1977-10-20
Abstract: The process for laying warning signs on a road surface, involves downwards open conical-type signs, superimposed and partially stacked (1, 2, 3), laid so that a stack-carrying retainer (5) is thrust sideways from a closed to an open position. The bottom sign (1) then falls out of the stack, and at the same time an upper retainer (12), partially below the next sign (2), and in a closed position prevents, the other signs for dropping. The bottom retainer returns to its closed position, and the upper one is opened, so that the whole stack drops onto the bottom one and the upper one moves back to its closed position. The process is repeated, with one sign laid each time, the signs being lowered either directly or via a slide track, or conveyor belt or chain. The process is mechanised.

Title: Sliding door for insulated partition wall - has perforated screens round heat insulation and screen battens through overlap area
Inventor: MECHEL KURT
IPC: E06B5/16
Filed: 1978-03-17
Abstract: The door comprises a leaf travelling in guide-rails between stops in front of a doorway bounded by floor and frame, esp. in connection with prefabricated partition walls. When closed it overlaps the frame to an extent matching door thickness. On the frame sides and door edges are screening battens forming a pocket and interlocking when the door is closed.

Title: Heat pipe for cooling electronic appts. - incorporates ceramic electrical insulation between hot and cold ends made of metal
Inventor: ROHNER PETER DR RER NAT
IPC: H02B1/56
Filed: 1978-05-11
Abstract: The object is to cool items of power electronics equipment for example thyristors which are electrically live and where normal cooling methods are insufficient.

Title: Batch wet-processing of lightweight fabrics - by joining several lengths at leading edges into one multilayer rope
Inventor: SCHUIERER MANFRED
IPC: D06B3/26
Filed: 1978-11-15
Abstract: A method of batch wet-processing lightweight textile materials in rope form whereby the leading ends of several, pref. 2 lengths are sewn together, the several lengths are fed together into the processing appts. and the trailing end of the longest length is joined to the common leading edge to form a continuous rope.

Patent DE-2911215-A1 (DE)
Title: Malt kiln heat recovery - by heat exchange between flue and waste gases and intake air
Inventor: HELMS ROLF
Filed: 1979-03-22
Abstract: The waste heat from the heating system of indirectly heated melt kilns is recovered in a heat exchanger for the fresh air entering the heating unit. The heat exchanger receives both the waste gases from the melt kiln and the flue gases from the heating boiler. This compensates for the 20% extra heat required for indirect heating of melt kilns, yet avoids the risk of care-inogenic nitrosamines in the malt which may be produced by direct heating. Fresh air passes through a heat exchanger (1) and a heating unit (2) before a ventilator (3) passes the hot air through the malt kiln (4). A heating boiler (5) with a blower and burner (7) which supplies the heating medium to the heating unit (2) is linked with the duct (6) for its flue gases to the waste gas duct from the melt kiln. The combined gas stream loses its heat in the heat exchanger (1) before it is discharged to atmosphere.
Patent DE-2918624-A1 (DE)
Title: Press-moulded ceramic chimney liner segments - has half housed spigot and socket joints and are stacked on end for firing
IPC: F27D3/12
Filed: 1979-05-09
Abstract: Applied to raw ceramics material, the press-moulding process is used to produce circular hollow chimney liner segments, each segment interlocking with those vertically adjacent by means of half housed lip joints. Moulded segments are dried and finally fired, having been placed on end in stacks on a kiln-wagon. The bottom segment is cut down to obtain a firing ring, the stacks inc. a firing ring, being assembled and handled as a unit in transit and through the drying and firing phases. The cutting down of the bottom segment may take place after a stack is assembled and after lifting for transfer to the wagon. A stack handling machine may be capable of pivoting, horizontal displacement and lifting, utilising a plunger arm with expanding mandrels taking a grip on individual segment bores.

Title: Descaling of workpieces, esp. round ingots or billets before forging - where hot rotating workpiece is exposed to jets of liq. in sound-proof chamber
Inventor: RAMM GUENTER
IPC: B21B45/08
Filed: 1979-05-11
Abstract: The workpiece, e.g. an ingot, is lifted off a conveyor by mobile tongs and carried into a washer where two mandrels clamp and rotate the ingot while it is exposed to jets of liq., e.g. water, so the entire surface of the ingot is descaled. The pref. washer consists of a cabinet with a mobile roof carrying the tongs. Inside the chamber are rows of water sprays used to blast scale off ingots which have already been heated, e.g. to the forging temp. No scale is left on any part of the surface of the workpiece.
Patent DE-2923453-A1 (DE)
Title: Welding multichamber thermoplastic profiles - for window and door frames, rebating outside walls to eliminate visible welds
IPC: E06B3/96
Filed: 1979-06-09
Abstract: In the zone of the surfaces which will be visible when a welded butt joint is made between hollow profiles of synthetic material, the edges to form the visible joint are set back relatively to the edges to be welded, by an amt. corresp. to the material required for the weld. The projecting edges of the profile are then raised to the welding temp and the profiles are pressed together so that the setting back of the visible edges is eliminated and the welded seam is formed underneath. Setting back of the edges is effected by a milling cutter, and the machining to size and the setting back are carried out in one operation. The walls of the core forming the welds are thicker than the circumferential walls of the profile, and the distance of these walls from the visible outer walls is such that the welded seam made lies against the butting edges of the outer walls which are filled by a glue. Frames for doors and windows can thus be assembled without it being necessary to have an additional operation for trimming off the visible welded seams.

Title: Milling machine with two work-tables - has work-tables simultaneously in same or opposite directions
Inventor: TRETOW WERNER ING GRAD
IPC: B23Q1/66
Filed: 1979-08-10
Abstract: A milling machine has two worktables (4,6) which can slide on the machine bed (28). The worktables (4,6) can be connected either separately or together to a block (14). This block has an internal thread which engages the thread of the screwed rod (16). The screwed rod (16) is driven through a toothed belt (18) from a motor (20). A second screwed rod can be coupled as required with the first screwed rod (16). With this arrangement it is possible to drive both worktables simultaneously in the same or in opposite directions. Thus one table can be in operation while the other is being loaded or unloaded.

Title: Removing nitrogen from argon in purification process - involves heating to reaction temp. before introducing into chamber contg. titanium sponge
Inventor: ZOCHE MICHAEL
IPC: B01D53/00
Filed: 1979-12-17
Abstract: The gas mixt. before entering the reaction chamber is passed along a hot surface in a heating chamber to bring it to generally uniform reaction temp.. The mixt. leaves the heating chamber at its perimeter and enters the reaction chamber through a sieve base supporting the sponge, then leaving the reaction chamber near its axis. The gas inlet and outlet are in heat exchanging relation, with the hot outgoing gas pre-heating the incoming gas. A sensor measures the hot gas temp. and is used to control heating. The appts. is also claimed. Used esp. for purifying the protective argon in glove-boxes. The uniform gas temp. in the present system prevents localised over- heating, esp. of small titanium particles, which can bond them together, and make removal difficult, or even destroy the reaction chamber, esp. when oxygen has entered.
