Device for drilling a hole of predetermined depth having an abutment member non-rotatable in relation to the stationary part of the drilling machine and provided with an abutment surface intended to come into contact with the work piece by the displacement of the drill spindle of said drilling machine towards the work piece, a driving member intended to be connected to the drill spindle said driving member being rotatably and displaceably arranged in relation to the abutment member, a holding me...

A quench strobe is provided with a resistor for effecting the quenching thereof at a predetermined rate which controls the amount of exposure influencing artificial illumination emitted subsequent to the quench trigger signal so that such exposure influencing artificial illumination closely correlates to the amount of exposure influencing illumination normally expected subsequent to the command signal to close the camera shutter blade elements and automatically anticipated by the camera exposure...

A device for dispensing a predetermined quantity of a liquid comprises: a pipette (1) constituted by a rod having a substantially spherical open element at its end, the element having a calibrated internal volume; mechanical device for holding this pipette either in a first position (51) for filling and for calibration purposes, or else in a second position (52) for emptying purposes; and mechanical device for rotating the pipette at high speed.

A method of forming a decorative shape from a concrete block by cutting the block into a predetermined shaped piece, polishing all flat surfaces and then applying a coating of clear material to the surface of said piece.

Apparatus for forming elongate laminate into a predetermined configuration having a substantially uniform cross-sectional shape in the axial direction, including a plurality of roller pairs having complementary transverse peripheral profiles, plate members disposed between the roller pairs and the laminate and having a transverse configuration corresponding to the peripheral profiles of the rollers.

Prosthetic device such as bone plates, stem-type prostheses such as femoral or humeral prostheses, or intramedullary rods are substantially improved by utilizing casting techniques that provide columnar or monocrystalline grain structure, with the <001> crystal direction oriented substantially parallel to the neutral axis, thereby increasing flexibility of the prosthesis and increasing loading on the bone, whereby disuse-atrophy is reduced and bone healing is facilitated; similarly, the cr...

A method for producing a predetermined resist pattern on e.g. a lithographic printing plate, circuit board or mask, comprises the patternwise exposure to suitable radiation of a composition which comprises a novolac resin and a diazonium salt. The composition is rendered preferentially soluble to a developer in the regions which were exposed.

A system for communicating data via a cellular network control channel of a cellular mobile radiotelephone system. The system includes a mobile switching center operable for receiving a registration signal from a registering cellular communications device. The registration signal includes identification information associated with the registering cellular communications device and a predefined data field containing data. The mobile switching center detects the presence of the identification info...
