Title: Thermoplastic corrugated tubing prodn - by extruding on to a mandrel inside a system of rotating eccentrics
Inventor: HERMANS INGRID M A C
IPC: B29C48/09
Filed: 1972-12-20
Abstract: An extruder with ring nozzle feeds on to a mandrel. This is located inside a moulding ring which has a suitably corrugated profile. The ring itself lies inside an eccentric and this in turn is inside an outer eccentric, the two eccentrics being adjustable in relation to each other. They are driven round eccentrically on the moulding ring which acts on the tube on the mandrel. The system therefore produces internally/externally corrugated or threaded tubes without flash or seams.

Patent DE-2357225-A1 (DE)
Title: Induction heating in rolling line - variation in heat radiation measured without contact line stoppage reduced heating
Inventor: RUNTE EDOUARD
IPC: G01P13/00
Filed: 1973-11-16
Abstract: An electronic control system is for induction heaters used in a metal rolling line. A stoppage automatically reduces or cuts out the heating. A thermal radiation detector (SD) mounted close to, but not touching, the surface of a bar (K) passing through induction heaters (SPI, SPII), has its movement continually monitored and a varying signal generated due to the thickness of the oxide coating on the steel alters the radiation emitted. After ampliying (V) and filtering out (HP) the continuous element, the remaining signal is used to control (GR, St) the level of heat supplied by the heaters. If the bar stops, this signal disappears and the heat is reduced.
Patent DE-2359158-A1 (DE)
Title: Plastic safety helmet with lining - has turned rim at lower edge holding straps
Inventor: LUNDIN TORD
IPC: A42B3/14
Filed: 1973-11-28
Abstract: The safety helmet shell is made from thermoplastics by injection moulding. The strength of this shell is increased by a moulded open turned rim at the lower edge of the shell. This rim carries a steel wire loop for holding lining straps. This arrangement eliminates the use of holes which weaken the shell. The steel wire rim also eliminates the need for internal reinforcement. The lining straps are connected to the steel wire which runs in the downwards open rim. This rim has narrow sections and the wire is pushed into the groove by shap action. The circular band is connected by bolster pads to the shell. The folded edge is a continuation of the beak and diverts rainwater.

Patent DE-2407067-A1 (DE)
Title: Concrete reinforcing bar rolling mill - has three swivelling rolls producing radii and ribs in one pass
Inventor: SIGRIZ PAUL VON
IPC: B21B1/16
Filed: 1974-02-14
Abstract: A ribbed rolling mill stand for the forming of ribs on reinforcing bars for ferro-concrete consists of three ribbed rolls which carry on the centre of their conical periphery the desired profile for deforming a bar. The ribbed rolls are supported by a bearing block which can be swivelled around an axis parallel to the roll axis by thrust pins, mounted on a common thrust plate, which act on a swivel plate on each bearing block. This saves the laborious setting operations which are required if the reinforcing bars are deformed in two stages; one pass through both increases the radius of the curvature at the required sections and imprints the ribs. The adjustment for the processing of different bar diameters is much simpler.

Title: Safety ski fixture with hinged boot plate - has spring loaded anchor plate disengaging under excessive torsion load
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: A63C9/085
Filed: 1974-05-04
Abstract: A safety ski fixture has a boot plate which hinges about a cross pin near the toe end of the boot. The hinge pin is held in two supports which are fixed to a round swivel plate. A spring loaded tapered location bolt engages in a notch on the swivel plate to retain the boot plate in line with the ski when the heel clamp is disengaged. This is the case for cross country skiing. When, during a fall, excessive torsion forces act on the boot, the location bolt is forced out of the notch, allowing, the plate to swivel thus protecting the leg. The spring load behind the location is adjustable to match the weight of the skier.
Patent DE-2425857-A1 (DE)
Title: Tent-type collapsible shelter - mechanism moves frame between transport and erected settings
Inventor: ZIEGLER HUGO DIPL ING
IPC: E04B1/344
Filed: 1974-05-28
Abstract: A transportable tent or shelter has bars joined together by hinges, with a stop to fix them in the erected position, forming a skeleton framework on which an external sheathing is mounted. Transition from the erected position to the transport position or vice versa, is effected by activating the hinges. At least one device generates the forces carrying the bars from one position to the other, transmitted by elements in the area of the hinges, from one bar to the next. There may be a traction cable in the area of the hinges, and a cable roller near the hinge axis, on a rotatable mounting, with the cable wound round it at least on the side facing away from the adjacent bars. There may be a helical cable groove on the rollers, and the cable can be made of elastic material, with a windlass at one end. Erection is easy and rapid, involving minimum effort.

Title: Portable grill rack for open fires - inclined closely spaced grooved bars with fat collecting trough
Inventor: BUESING OTTO
IPC: A47J37/06
Filed: 1974-06-07
Abstract: The barbecue grill rack has bars connected together on the underneath facing the flame by rails wherein the bars themselves have a V-shaped cross section which is open towards the food to be cooked. These V-shaped bars (1) are slightly inclined in their longitudinal direction and are spaced from each other in the transverse direction such that they cover most of the flame and embers, thereby preventing the food from burning. A fat collecting trough (4) can be at the lower end of the grid so that the fat can run down the grooves and be collected. Since the heat is taken up by the grid and evenly distributed, the good is cooked more evenly.
Patent DE-2429309-A1 (DE)
Title: Tubular material filling and packing machine - has clips fed to two heads opposite to those twisting them
Inventor: WELLS ROY EARL
IPC: B65B9/20
Filed: 1974-06-19
Abstract: The machine fills a tube of packing material with material to be packaged and ties it off a regular intervals by means of flexible U-shaped clips, delivered to a tying head moving in relation to the packaged material. Two heads are provided to accommodate the clips, operating alternately in the horizontal direction in relation to the winding heads opposite them, which ar arranged close together, one above the other. Each winding head incorporates components accommodating the two free ends of a clips as it is delivered in the horizontal direction, and which bend them diagonally in relation to the horizontal part of the clip round the packing material. Thus the clip ends overlap and run parallel to each other, leaving a common limitation device between them inclined to the horizontal.

Title: Anti-freeze applicator for hydraulic systems - has ram-piston with pressure-charged reaction surface
Inventor: BLANZ ROLAND
IPC: B60T17/00
Filed: 1974-11-26
Abstract: The applicator esp. for vehicles has a ram piston, guided in a housing. The piston passes through the pressure conduit, and may be manually axially adjusted and fixed. The piston is surrounded by a wick, projecting into the chamber, which is filled with antifreeze. A seal is fastened to the piston, to seal the chamber against the pressure conduit. The piston has a reaction surface, charged by the pressure in the conduit, to move it into its operating position. In the at-rest position, the reaction surface may be blocked by an element. When operating, the reaction surface has a pressure relief. The reaction surface forms a compensation chamber on the side of the housing away from the pressure conduit. In the operating position, the chamber is aerated, and evacuated, in the at-rest position.
