Title: Die cast steps for escalators - shafts are cast into step bodies in sections under tension
Inventor: LANDSCHULZE ERNST-AUGUST
IPC: B66B23/12
Filed: 1975-04-25
Abstract: Die cast steps for escalators where the aluminium die cast bodies are provided with one or more cast-in shafts passing through from one side to the other. These shafts are moulded in the region of those sections of the steps which are in tension. Specifically the die cast bodies of the steps can be of aluminium or some other material such as plastic. Consequently these shafts or reinforcing bars, which are specifically of steel take over the stress loading in the step and at the same time act as shafts for the rollers.

Title: Metal removing machine tool guideways - with slide on round guide bar supporting slide bar for tool in cross bore
Inventor: WASILIEW WLADIMIR SERGEEWITSCH
IPC: B23Q1/62
Filed: 1975-05-28
Abstract: The metal-removing machine tool is equipped with a first slide which can be moved by a leadscrew drive along a guide bar, fixed at both ends to the machine bed. This slide has a bore which acts as a guide for a second slide, represented by a round bar with a cantilever plate at one end. This plate is connected to another leadscrew drive for a motion at right angles to the first slide. The other end of the bar has a flange to which the cutting tool or the erosion electrode can be attached. These guides have a less complex shape and have a greater cross-Sectional area than prism-shaped guides. The guide bar (8) is fixed at the ends to the machine bed (1). A slide (10) can move on it in a linear bell bearing (16), driven by a motor (20) with gearing (21) and a leadscrew (22). A cross bore (11) in a plane parallel to that of the bore (9) but normal to it guides a bar (12) with a flange (13) for the attachment of the cutting tool.

EAch cam groove comprises a straight side and a curved side which are interconnected by a semicircle.
Patent DE-2530610-A1 (DE)
Title: Attenuation equaliser for telephone exchanges - alters semiconductor crosspoint attenuation to keep value of total attenuation constant
Inventor: GLEMSER JUERGEN DIPL ING
IPC: H04Q3/52
Filed: 1975-07-09
Abstract: The attenuation equaliser is used for telephone exchanges with semiconductor crosspoints. It change over the s-c crosspoint attenuation from low to high for low line attenuation and from high to low for high line attenuation. The total attenuation is thereby kept within limits simply by altering the s-c crosspoint attenuation, with the result that special circuits are not required. Where transistors are used as crosspoints, their direct current is altered so as to vary their attenuation. Where MOSFETs are used, their gate voltage is varied to set the attenuation high or low. The attenuation is set according to 'internal connection' 'external connection' or 'external private exchange'.

Title: Foot roller support for prone exercising - has bracket enclosing foot with ball in cup at toe
Inventor: KERSTEN KLAUS J ING GRAD
IPC: A63C17/08
Filed: 1976-01-09
