Patent DE-2345468-A1 (DE)
Title: Coin ejection mechanisms for change machines - are of various kinds and are designed to deal with bent coins
IPC: G07D1/02
Filed: 1973-09-08
Abstract: Various simple mechanisms are described for ejecting coins from a coin stack in a vertical tube, for use in change or change-giving machines. The simplest device, already in use, consists simply of a vertical tube mounted above a horizontal plate with a gap in front at the bottom of the tube and an ejector mechanism behind. The ejector simply pushes the coin through the gap and the next coin falls into place under gravity. Bent coins can jam this mechanism and various ideas are presented to overcome this problem. The first consists of a sprung "curtain" in front of the tube rather than a simple gap. This rides up over any bent coins. Two forms of such curtain are described. A hole may be in the plate below the tube less than coin size, so that all coins settle properly on the plate even if severely bevelled. This aligns them with the ejector.

Title: Mfr. of spherical magnesium powder - with passivated surface obtd. using air mixed with sulphur hexafluoride
Inventor: ROHR HORST
IPC: B22F9/08
Filed: 1973-11-05
Abstract: The powder is made by melting magnesium and spraying it into a protective atmos. of air contg. 0.2-60 vol. % pref. 0.2-5 vol. % SF6.

Title: Mat for protection against water erosion - has sandwich construction with reduced water flow resistance on landward side
Inventor: MUEHRING WALTER
IPC: E02B3/12
Filed: 1974-06-27
Abstract: In the construction of water works a protective mat is required to prevent the surface of the dam wall against water erosion. This is provided by a sandwich construction mat with fibrous material on both sides, the water resistance on the side facing the water waves (3) being greater than that on the landward side (1). This has the effect of slowing down the potentially erosive sand or grit particles and at the same time permitting the water to stream back freely after each wave recedes. The layers are bonded by a central section of large pore material (2). The normal calm water level (7) is ideally part of the way up the mat.

Title: Reciprocating piston compressor volume control - has rotary valve members with cutaways alignable with supply and discharge ports
Inventor: WANKE WILHELM
IPC: F04B1/30
Filed: 1974-11-18
Abstract: The control device is for compressors with a fixed stroke and has a rotary member located in the supply and delivery port of the chamber.
