Patent DE-2344013-A1 (DE)
Title: Mimic display design for complex systems - depends on decoding address and command information to light appropriately displayed lamps
Inventor: SCHAICH GERHARD
IPC: H04Q3/545
Filed: 1973-08-31
Abstract: The system displays the state of some complex electrical or electronic system, such as a telephone exchange. Essentially the idea is to decode the information driving the system, consisting normally of address and command information, in much the same way that the individual units of the system must themselves decode it. Once decoded, however, this is used to set flip-flops which inturn light lamps on a suitably constructed mimic diagram, so that the various connections or switch positions in the system can be displayed conveniently. This avoids the need for all the state switches in the system to be linked directly to some central display which would be impossibly complicated and expensive.

Title: Connector for nailable workpieces - formed as a U-shaped metal strip with profiled teeth projecting on each limb
IPC: F16B15/00
Filed: 1973-11-03
Abstract: After connector is partly driven home it is fully inserted so the teeth are wholly sunken into the workpiece and the U-shape is almost flattened on to the surface. The teeth, in pairs, are slightly bent inwards or outwards so that during insertion they curve and hence grip the material securely. The teeth are given a formed profile. The line down the centre of each tooth shows the ridge of an obtuse V-shape extending from root to tip. The V-shape in each tooth may be pressed inwards (so that from the outside one looks into the valley) or may be pressed outward (so that one looks on the crest). Instead of a V-shaped profile a curved shape or a three-sided angular shape may be used.

Title: Adjustable surfaces for wind propelled boat - has aerofoil carried on arms pivoted to rotatable base at boat centre
Inventor: BARTHOLLY WOLFGANG ING GRAD
IPC: B63H9/06
Filed: 1974-07-02
Abstract: The aerodynamic drive-and buoyancy surface automatically turns into an optimum air flow direction. The resultant of the occuring air forces extends through the centre of gravity or any other chosen point of the craft. The horizontal air force component of the buoyancy surface, borne about the Z-axis, simultaneously causes its optimum adjustment to the air flow. This is due to the point of impact of the air, in direction of flow, being positioned at a distance behind the Z-axis. The buoyancy surface is suspended in a trapezoidal bearing in four hinge points, so that the resulting aerodynamic force may be directed into a selected direction.

Several boards may be enclosed in the same cassette.
Patent DE-2461293-A1 (DE)
Title: Controlled cooling of hot metal parts - for natural structural transformation followed by rapid cooling free from internal stress
Inventor: HILGEROTH ERICH
IPC: C21D1/84
Filed: 1974-12-23
Abstract: This is an addn. to 2432765, which described a process for cooling h ot metal parts, esp. castings from a mould, or steel parts or strip leaving a furnace, where the parts travel through min. two cooling zones, the first zone using cooling by radiation and/or convection for the natural structural transformation of the metal parts, and the subsequent cooling zones using progressively stronger cooling by convection and/or evapn. cooling. The first zone is used for cooling down to 720 degrees C for completion of the natural or desired structural transformation whereas the subsequent cooling zones prevent internal or residual stress (lattice distortions) and the cooling follows a convex curve with an increased cooling speed. Used e.g., in the prodn. of nodular graphite cast iron, 90% of the castings cooled by this process and shot-blasted can be directly machined without the necessity for a prior annealing treatment.
