Title: Indicator lamp dimming control - has two bulbs connected as voltage divider with indicators linked to centre tapping by light switch
Inventor: SPANBALD BRUNO
IPC: B60Q3/04
Filed: 1976-05-12
Abstract: The indicator lamps (19) for the automatic transmission and other systems are provided with a dimming control operating when the vehicle lights are switched on. This comprises two similar bulbs (7, 8) connected as a voltage divider, and with the indicators linked to the centre tapping by the light switch.

Title: Electrohydraulic pressing with automatic wire supply - for electrode contact fed through chamber opening and cut off by knives inside chamber
Inventor: TSCHATSCHIN VIKTOR NIKOLAJEVIT
IPC: B21D26/10
Filed: 1976-06-25
Abstract: Equipment for electrohydraulic pressing, which contains a non-movable plate with an explosion chamber mounted on it, inside which is an electrode. In the wall serving as the other electrode, an opening is formed for passage of an electrical connection wire, and, opposite the chamber side on which the die is pressed, the chamber has a step slightly smaller than the opening for the wire. Near this opening two knives for cutting the wire are present. One of these is fixed and the other can be displaced in the direction of the chamber geometric axis so that the wire is cut and the cut portion is supported by the step. Complicated shapes in difficult materials are formed. Welding of the wire to the chamber wall is prevented and the wire is cut automatically.

Title: Equilateral triangular map aligned on grid lines - is true to scale angle and area and mosaic of such maps can be made up into globe
Inventor: FIRLUS WILLIBALD DR
IPC: G09B29/02
Filed: 1976-09-11
Abstract: The edge of the triangular map is true to scale. It is true with respect to area, and angle and it is always identical to the trend of a particular orthodrome. This means that maps of this kind, unlike plane-table sheets, can be made up into a globe. Such a map is very useful for navigational purposes because its range at the edge of the map encompasses a region with a length of approximately 381 km. With a scale of 1:500,000 it will require 8,000 of these maps to produce a perfect copy of the entire surface of the earth.

Patent DE-2709776-A1 (DE)
Title: NC machine tool for forming internal worm gear - has spindle coupled to impulse generator supplying tool control circuit to lift tool clear after each cut
Inventor: HENJES GUENTHER
IPC: B23G3/00
Filed: 1977-03-07
Abstract: The machine forms spiral gear teeth inside a hollow cylinder, being numerically controlled, and turning the cylinder by a main spindle. An impulse generator coupled to the spindle supplies a control circuit, determining the point at which the axially-sliding tool begins its cut, in accordance with the desired interval between the grooves. This circuit also lifts the tool clear of the work surface after each cut, and returns it to the starting position for the next cut. The design allows internal spiral grooves to be simply machined with a higher degree of accuracy.

Title: Controller driving the hearth of rotary hearth furnace - so ingots being heated do not produce uneven wear of hearth
Inventor: PARDON PETER ING GRAD
IPC: F27B21/14
Filed: 1978-01-05
Abstract: The furnace is employed to heat ingots to their hot working temp. The hearth rotates stepwise, using a whole number of steps between the charging door (a) and the discharge door (b), but the number of steps from door (b) to door (a) is reduced by a fraction of a step, e.g. by 1/2, 1/3, or 2/3 of a step. the number of steps from door (a) to door (b) is pref. 113; whereas 6.5 steps are used between door (b) and door (a). One gear wheel in the drive unit pref. has an odd transmission ratio to produce the motion required. Conventional hearths rotate in uniform steps, e.g. of 3 degrees. The result is that the ingots are always carried by the same zones on the hearth; these zones remain cooler than the remainder of the hearth and also wear faster so as uneven hearth is obttd. The invention ensures that all the hearth is used and even wear obtd.

Title: Aerodynamic aircraft wheel rotating system - uses paddle blades shaped as hemispherical cups attached to wheel hub
Inventor: HUNFELD HANS-HERMANN
IPC: B64C25/40
Filed: 1978-05-18
Abstract: Paddle blades (3) are either attached to the aircraft wheel or formed in the wheel casting itself. They are so shaped that the profile of the lower half presents a greater resistance to the airflow that the upper, thus causing the wheel to rotate before contact with the runway. If separate from the wheel casting, the blades may be in metal, plastics or ceramic. The principle is the same as that in certain types of anemometer, the blades being shaped as hemispherical cups.
