Title: Gate power drive with safety stop - has spring deformed by obstruction to actuate motor control switch
Inventor: HOERMANN MICHAEL DIPL ING
IPC: E05F15/684
Filed: 1976-10-29
Abstract: A fixed drive motor operates the gate by a chain connected directly or indirectly on the gate. The drive motor is rapidly switched off or reversed if an obstruction is met. When the gate meets, at least in the closing travel, an obstruction then a spring (19, 12) is deformed. This spring is in contact with part (21) of the drive motor (1). The deformation movement is directly or indirectly transmitted to the actuator (15) of a switch (14). The motor (1) is tilted about an axis by the force exerted by the deformed spring. This movement actuates the switch for stopping the motor.

Title: Cavity formation in flanged double-walled vessel - with shuttering on cylindrical inner surface and release medium on bottom inner surface
Inventor: ASCHER ADOLF
IPC: B65D90/02
Filed: 1976-12-04
Abstract: Formation of the cavity of a flanged double-walled vessel comprises applying a shuttering element, with a thickness corresponding to the desired spacing of the walls, to the inner vessel surface facing the cavity in the region of the cylindrical portion and rim, and applying a release medium to the same surface in the region of the bottom membrane. The remaining cavity between inner and outer vessels is filled with reactive foam. The shuttering element is removed, and the distance between the bottom membrane of the inner vessel and foam is adjusted by inserting a seal of suitable thickness between the flanges of the two vessels to be screwed together. Flow properties of a heat exchange medium are improved without affecting safety requirements.

Title: Replacement of enamelled metal bath with masonry and tile cladding - involves cutting new bath edges to fit cladding which is retained
Inventor: AHRENSMEIER ERICH
IPC: E04G23/00
Filed: 1976-12-14
Abstract: The process is for replacement of baths made of enamelled sheet steel or enamelled cat iron, firmly built into position and cladded with masonry and tiles in the sidewall area. Mortar fixing the bath tub edge is first removed and then old bath is then cut away with special tools, and removed from the cladding, which remains. The edge of the replacement bath is cut to fit this remaining cladding, and the bath is inserted into it, joint gaps between bath edge and cladding being sealed with mortar. A metalworking hacksaw can be used for cutting the new bath to fit the cladding, the enamelled surface being protected by an adhesive strip cemented along the cutting line. This system enables replacement to be effected without fitting new cladding.

Title: Liq. level sensor with vertical guide tube - has free float magnetically latching switch reeds as it passes in one direction and unlatching in opposite direction
Inventor: BONGORT EDGAR A
IPC: G01F23/74
Filed: 1977-01-24
Abstract: A liq. level sensor has a guide tube for vertical positioning in the liq. concerned. A float, surrounding the tube, rises and falls with the liq. level. A reed switch in the tube has its reeds extending parallel to the tube axis.
