Title: Anti-arcing protection for overhead conductor rail - with extending horns with fuse links to isolate arc
Inventor: HEIGL HANS
IPC: B60M1/18
Filed: 1974-08-06
Abstract: Special anti-arcing horns are fitted to either side of the insulating section on the overhead electric supply line. The horns have a main shaft which leads upwards into an insulated (5) tube. The shaft is circular in cross section and is split into upper and lower sections inside the insulating tube. The two parts are joined by a piece of fuse wire (7). As the arc climbs upwards between the horns it crosses the fuse wire, which melts after a set time interval. The secondary arc across the burnt out fuse wire heats and expands the air inside the tube and thus helps the internal spring to throw the upper shaft section outwards.

Title: Device for detecting jamming in a forming die - uses high voltage spark between jammed workpiece and electrode on the die
Inventor: THEISSEN DIETER DIPL ING
IPC: B30B15/28
Filed: 1974-10-15
Abstract: The system for detecting the presence of a workpiece in a press tool is used in automatically operating deep drawing presses, and ensures that no new blank is fed into a die before the previous workpiece has been ejected. This prevents production of scrap and protects the dies. The detector is stable against impact, dirt and heat. An electrical pulse is generated when a workpiece is still in the die and the machine is stopped. This arrangement uses an electrical spark which is generated on a jammed workpiece which acts as an electrode. This spark generates a pulse which interrupts the feed of a workpiece blank to the die. The spark is generated between the electrode (10) arranged on the edge of the die (13) and connected to a high voltage source (7) which can be a piezo crystal or an induction coil.

Title: Imparting natural live appearance to animal skin or hide - by making an intermediate positive model from a negative mould
Inventor: WENDT ALFRED
IPC: B44C3/04
Filed: 1974-12-07
Abstract: A "stuffed" animal, having the natural appearance of the live creature, is mfd. by making a negative mould of the animal to be displayed so as to obt. an intermediate positive model. This positive is then suitably reduced according to the thickness of the pelt or skin or hide being used, and then finished to take account of anatomical (e.g. muscular) details and characteristics of the living animal. From the intermediate positive, a multi-parT, closable negative mould is made of metal. This is then filled with a casting or injection material via a short feed pipe and opt. vented via orifice(s). The resulting positive cast is removed, after hardening, and covered with the pelt, skin or hide.

Title: Powdered metal part having bearing surface - e.g. ball bearing race having resistance to spalling and high tensile strength
Inventor: FERGUSON HOWARD A
IPC: B22F3/16
Filed: 1975-01-30
Abstract: A highly densified metal part having a high density bearing surface is formed by compacting powdered metal into a preform which is then sintered and cooled, placed in a die at room temp. and subjected to tensile and shear stresses commencing at the bearing surface and progressing through the remainder of the preform to elongate the grain and pore structure, and applying compressive stresses first at the bearing surface and then at other surfaces as the tensile shear stresses approach the point of fracture of the preform and cause collapse of the elongated pores and welding of the grains across the collapsed pore boundaries throughout the powdered metal part. The method is used for making ball bearing races of excellent spalling resistance, high compressive yield strength and tensile strength for the bearing raceway. No further machining to improve the surface finish is necessary.
Patent DE-2504693-A1 (DE)
Title: Hydraulic drive and braking system - with central pump and separate hydraulic motors linked to central control valve
IPC: B60T1/08
Filed: 1975-02-05
Abstract: The vehicle is fitted with a variable output hydraulic pump driven by the engine at its most economical running speed. A central control supplies fluid to the separate wheel drive motors for improved torque control. At low speeds four wheel drive is used, while above a set speed two wheel drive is automatically set. The driver merely operates the single control in the selected direction, and for the selected speed. For braking control the servo motors act as dynamic retarders. The vehicle has no bulky transmission tunnel nor any complex transmission linkages, only hydraulic lines, while the engine operates at its most economic speed.

Title: Electrical distribution system contained in cavity floor - is extended to include central heating system using pipes running through floor
Inventor: GEIER OTMAR
IPC: H02G3/03
Filed: 1975-08-18
Abstract: The distribution system for power and light current electrical services is carried on a solid sub-floor from which the main floor, made in panels, is carried. The panels hold the socket outlets, and the system is constructed as in 2353865. The cavity in the flooring system can be further utilised for heating or cooling the associated rooms. Piping for a hot water central heating system, or electrical heating elements, are arranged just below the floor panels and may be insulated from the heat sink formed by the solid sub-floor. The large heat emitting area thus available permits the use of a small temperature difference between room and heating medium, thus low grade heat may be utilised. A circuit employing a heat pump could be used for cooling or as part of a temperature control system.

Title: Drawer guide assembly with antitilt guide element - allows all round compensation for manufacturing tolerances
Inventor: GRASS ALFRED
IPC: A47B88/493
Filed: 1975-11-04
Abstract: So that the drawer does not tilt sideways when moved in and out a guide element such as a roller (5) or a slide member is mounted on guide rails to be supported against the other associated guide rail and is adapted for adjustment so as to remove the play between the guide rail (4) which is fixed and the displaceable guide rail (3) which is parallel to the side wall (2) of the drawer. The guide member is now no longer fixed resilient to the locally fixed guide rail but is rigid and adjustable and this rigid attachment allows large forces to be transferred to the guide element without the latter yielding.

Title: Fading:in of white spot into video telephone picture - uses light pencil applied first to bright spot near required point and then moved to that point
Inventor: LAMPL JOSEF
IPC: H04N7/14
Filed: 1976-06-28
Abstract: The fading uses a light pencil with a photoresistor, or a similar photosensitive cell, and the spot can be seen on screens of both subscribers. The pencil is attached to a coordinate input device which determines the position of the spot on the screen, when the photoresistor at the light pencil tip touches the screen. When a black area exists at the point where the white spot is to be faded-in, the photoresistor is at first applied to a brighter point of the picture near the point to be marked. The white spot so produced on the screen excites the photoresistor by optical feedback to generate a white spot, when the pencil is moved to the point where the spot should be produced.
Patent DE-2634967-A1 (DE)
Title: Dry hot compressed air for blast furnace - produced using heat exchanger and dehydrator assembly upstream of hot air furnaces
Inventor: YOSHIDA TORU
IPC: C21B9/16
Filed: 1976-08-04
Abstract: The air passage between a blower and hot air furnaces for a blast furnace incorporates a dehydrater assembly having a gas permeable rotor impregnated with a regenerative hygroscopic substance and a cooler for condensing the moisture in the air. a heat exchanger is arranged in the passage so that some of the hot compressed air coming from the blower can transfer its heat to the dehydrated air coming from the dehydrated assembly. All the air to be introduced to the hot air furnaces is passed through the dehydrater assembly and the heat exchanger and is dehydrated. It is unnecessary to supply any external hot air to regenerate the rotor. The moisture content of the treated air can be reduced without any significant loss of temp. and pressure. Air leakage between the regenerating and dehydrating zones in the dehydrater is prevented by sealing clearances with packing elements and externally introducing dry pressurised air into the sealed spaces.
