Title: Machine for dressing grinding wheel to involute profile - has combined rotation and linear motion to generate desired shape
Inventor: STARK KLAUS
IPC: B23F23/12
Filed: 1977-11-25
Abstract: A grinding wheel with an involute profile for grinding involute gear teeth is dressed to form by three tools (10, 11, 12). These tools are mounted on an arm (4) which can rotate about a horizontal axis. The arm (4) is mounted on a slide (2) which moves horizontally at right angles to the axis of rotation. The resultant motion from this combination of rotation and linear movement causes the tool (10) to generate an involute on one side of the grinding wheel whilst the tool (12) generates an involute on the other face. The tool (11) dresses the outside diameter of the wheel.
Patent DE-2753583-A1 (DE)
Inventor: HEROLD KAUKO KALEVI
IPC: H01H85/52
Filed: 1977-12-01
Abstract: A protection ring (11) consisting of electrical insulating material is fitted on a threaded sleeve (3) which is fitted on a fuse base (1) in order to protect the threaded sleeve against being touched accidentally. The protection ring is not intended to become detached from the threaded sleeve and is also in this case not intended to be rigidly connected to the threaded sleeve since, for example, a plurality of fuse elements (1+11) are intended to be installed in electrical group centres and, in this case, must project through a corresponding number of openings in a common protection plate. The inner surface of the protection ring is provided with gripping devices (12) which interact with a corresponding number of attachment tabs (9) which are arranged on the outer surface of the threaded sleeve. The respective gripping device is formed by means of a locking surface (14), which originates from a groove (13) and has a locking tab (16) and a stop tab (17). The attachment tab of the threaded sleeve is forcibly moved past the locking tab adjacent to the groove during assembly of the protection ring, so that the attachment tab then fixes the protection ring by interaction between the said tabs. <IMAGE>

Title: Solar heat collector overheat preventing system - uses bimetal strip to open space between cover and body
Inventor: VINZ SIEGFRIED DIPL KFM ING GR
IPC: F24J2/46
Filed: 1978-01-11
Abstract: The overheating prevention system is for use with a solar heat collector. A bimetal strip or other heat-operated device opens the space between collector cover and surface to the ambient air, causes a shade to be pulled over the collector, or runs cooling liquid over it. The cover (1) can be coupled to the collector body (3) by a bimetal strip (2), the latter also forming a cover suspension mounting and increasing the distance between the two on overheating. Alternatively a bimetal spring can be arranged to lift part or all of the cover clear.

Title: Circuit blocking codes or code groups in telephone equipment - differentiates between free and blocked code numbers by applying different potentials
Inventor: DIRR JOSEF ING GRAD
IPC: H04M1/677
Filed: 1978-02-14
Abstract: The circuit enables codes or code groups in telephone instruments or PBXs to be blocked although allowing emergency calls to be made. Electronic bistable switches are tripped to their operating position when a certain code number is dialled, or a certain potential is applied by a mechanical or electromechanical device. The bistable element is so inserted into a gate pyramid, that the system differentiates between marked free and blocked code numbers, with different potentials applied when code numbers are marked free or blocked. Switches differentiate this marking by operation or non-operation of a relay. The marking is erased by resetting the bistable element by a mechanical device or a gate pyramid.
