Title: Mounting of modular time switches - uses preassembly of external elements and final assembly after functional checking
Inventor: NEUBAUER JOSEF
IPC: G04C23/16
Filed: 1974-11-07
Abstract: The modular, digital cooking range time switches are mounted by assembling the individual parts of the timing switch externally to form a functional component unit, containing the housing with the lever system and motor, the switching system, the drive transmission system and the indicator group. These preassembled unit are adjusted and their functions checked. Subsequently the externally preassembled functional component units are mounted into the range in a predetermined sequence. Preferably the individual externally preassembled functional component units are mounted in the order: the switching system, the drive transmission system, and the indicating unit into the respective housing, after which the function checking of the groups is carried individually and with all groups together.

Title: Variable geometry wing mirror - operated by periodic servo when direction indicators activated
Inventor: BUECKER GUSTAV
IPC: B60R1/02
Filed: 1974-12-19
Abstract: The wing mirror has the mirror surface pivotted about an outside vertical axis to alter the angle of view for the driver. The mirror is swung by a servo motor, either a hydraulic or electric cam type, against a return spring force. The servo motor is operated in conjunction with the relevant direction flasher circuit to alter the angle of view periodically while the flasher operates. This provides a safe view for the driver with no dead angles while changing lanes and overtaking. A safety interlock inhibits the servo operation below set engine/road speeds.

Title: Tool for drilling holes and cutting grooves - has elongate channel member in channel in abrasive tip with end face recess
Inventor: FRENKEL SCHIMAN TEWELJEWITSCH
IPC: B23B51/00
Filed: 1975-03-07
Abstract: The tool is particularly for hard, brittle materials such as glass and ceramic and has a shank (1) which receives a cutting tip (2) of material containing abrasive. In a longitudinal slot in the tip is an elongate bar of material whose abrasive resistance is lower than and whose binding strength is higher than those of the cutting tip material. The surface profile of the bar is identical in cross-section to that of the slot so that the surfaces are closely mated. A recess (6) in the end face (5) of the cutting tip is arranged so that abrasive particles on the end face are located at and beyond a distance (a) from the axis (7) of rotation of the tool, so that a core pin formed in the hole being drilled thrusts against the curvilinear bottom (8) of the recess (6). The core pin abrades or breaks and abrades the bottom (8). The channel shape of the bar facilitates abrasion of the bar and allows a good supply of cutting coolant and removal of sludge from the cutting area.
