Patent DE-2535627-A1 (DE)
Title: Filter electrode for electrochemical gas detector cell - with metal layer on carrier diaphragm with profiles in form of corrugations or ribs
Inventor: KRAUS HEINZ
IPC: G01N27/30
Filed: 1975-08-09
Abstract: A filter electrode for a measuring cell in an electrochemical gas detector is a metal structure on a non-conducting carrier diaphragm which separates an electrolyte from the test atmosphere and is partially permeable to the electrolyte. The metal structure comprises a series of lines with multiple changes of direction, so that if the carrier diaphragm suffers a change in dimensions or shape the metal structure only undergoes a change in shape and retains its position relative to the diaphragm. The diaphragm has a profiled surface with e.g. corrugations, ribs, grooves, studs or similar structures.

Title: Flexible noise reduction skirt for railway vehicles - encloses noise absorbing material within rubber walls with reinforced lower edge
Inventor: KLAPPER HELMUT
IPC: B61D17/02
Filed: 1975-09-25
Abstract: The covering skirt is esp. for railway vehicles with bogies. The skirts are held on the coach body and are able to move in the bogie area. The skirts reduce the noise and the aerodynamic shape of the vehicle is mainted on travelling through track curves. The moving skirt (8) cells have flexible walls (12, 14, 16) which are bent towards when the bogie swings outwards. The moving skirt cells are connected to form an enclosed hollow body filled with a noise absorbing material. This hollow body is made from a hollow double walled rubber profile divided into sections by longitudinal ribs (12). The lower edge (26) of the profile is reinforced (28).

Title: Swell control for electric guitar - is repositioned so that it can be worked by the right forearm
Inventor: FRANZMANN RAINER
IPC: G10H3/18
Filed: 1975-10-15
Abstract: Known swell controls for electric guitars are operated by the player's foot, but provide only a coarse control esp. when the instrument is played standing. Other known controls are operated by the ball of the thumb, but this interferes with the freedom of the player's plucking fingers. The control is accessible to the forearm of the player's plucking hand. Pushing a knob down towards the body of the instrument moves a pivoted arm inside, and ultimately the slider of the volume control potentiometer. Rotating the same knob before starting to play sets a stop for the pivoted arm, corresponding to the min. vol. of sound desired.

Title: Sewing machine fabric advance device - having a linkage to lift upper belt from fabric without raising the presser foot
Inventor: LANDWEHR GUENTER
IPC: D05B27/04
Filed: 1975-11-18

Title: Water drain valve for compressed air vessel - has membrane operated hollow valve spindle normally sealed by floating plug
Inventor: SCHNATMEYER HANS DIPL ING
IPC: F16T1/20
Filed: 1976-02-11
Abstract: A discharge valve on a pressure vessel (1) for compressed air has a valve spindle (12) which is operated by a membrane (7). The valve spindle (12) which is hollow, penetrates the pressure chamber and is normally sealed off by a floating plug (16). When water collects at the bottom of the pressure vessel, the float is lifted and thus allows compressed air to reach the valve chamber (9). The pressurized membrane now moves the valve spindle upwards so that the seal ring (18) frees the discharge channel (11). When all the water has drained off, the discharge channel is closed again and the hollow valve spindle is covered up by the floating plug (16).

Patent DE-2707829-A1 (DE)
Title: Two layer stator winding for slotless machine - has four layer end winding to reduce overhang length
Inventor: BELOVA TAMARA NIKOLAJEVNA
IPC: H02K3/28
Filed: 1977-02-23
Abstract: In two layer stator windings of large machines, typically those which have no slots, the windings are located in the air gap. The end winding overhang is largely determined by the bar pitch round the stator bore, being inversely proportional to this quantity, thus closely spaced air gap windings tend to have a large overhang. This feature can be improved by arranging the end winding in four layers. The coil pitch is made such that the coil sides of one group are interleaved with those of another to enable the construction of a four layer end winding whose exact shape is determined by whether the coil span is even or odd. With this design the effective bar pitch round the stator bore is doubles allowing a corresp. reduction in overhang length.
