Abstract: The active portion of an osseous compression tool for use particularly in dentistry for the preparation of an osseous seat has a cross-section whose perimeter, e.g. of polygonal shape, is defined such that a rotational actuation of the tool around its axis, at least in one direction, preceded or accompanied by its actuation in an axial direction inside the seat, has the effect that the osseous matter is compressed and that the seat is imparted a perimeter of a predetermined shape. In a variant embodiment, a rotation of the tool in the opposite direction allows a scraping or cutting of osseous matter. A tool holder includes a percussion system and allows the translational and rotational actuation of the tool manually or automatically.

Title: Non-slip pneumatic tyre
Inventor: FELDMANN PAUL DIPL-ING DR
IPC: B60C11/14
Filed: 1982-06-01
Granted: 1983-06-09
Abstract: The invention with the description "non-slip pneumatic tyre" relates to a pneumatic tyre for motor vehicles which contains a granular powder in its elastic binding agent, the hardness of the grains of which powder is greater than the hardness of the elastic binding agent and which, preferably before being added to the elastic binding agent of the pneumatic tyre, has been sintered to form a coarse, porous structure and subsequently broken up. The method according to the invention for producing a non-slip pneumatic tyre of this kind consists in the fact that the granular powder is added to the binding agent of the pneumatic tyre before the vulcanisation of the elastic binding agent of said tyre.

Title: Tool for screwing in self-tapping threaded bushes
Inventor: STOEVEKEN BERNHARD
IPC: B25B21/00
Filed: 1983-04-22
Granted: 1984-12-06
Abstract: A tool for screwing self-tapping threaded bushes into smooth receiving bores has a reversibly rotatable shaft, at the ends of which is arranged a thread onto which the threaded bush can be screwed. On screwing this threaded bush into the receiving bore, a sleeve comes to bear non-positively against the face of the threaded bush opposite the screw-in end, which sleeve is locked to the threaded bush. This locking is effected by a counterholder which comes to bear against the sleeve during the screwing-in. In order that the threaded bush is not loosened in the receiving bore on unscrewing the shaft from said threaded bush inserted in the receiving bore, the non-positive bearing of the counterholder on the sleeve is eliminated before reversing the movement of the shaft.

Title: Ink-ribbon cartridge
Inventor: ACKERMANN ROLF
IPC: B41J35/36
Filed: 1986-01-20
Granted: 1987-04-09
Abstract: The subject-matter of the invention is an ink-ribbon cartridge for typewriters or printers having a device for detecting the ink ribbon. This device comprises contacts which are provided on the machine side and are bridged by means of a prestressed spring when the end of the ink ribbon is reached. In this case, the spring is held on the hub of the supply reel under prestress by means of the ribbon coil and is only released when the ink ribbon has been used up. The electric signal can be used for an acoustic and/or a visual display. The ink-ribbon cartridge also interacts with a contact disc which likewise bridges the contacts if no cartridge is inserted. The device thus also reports any lack of an ink-ribbon cartridge.

Granted: 1988-04-21
Abstract: A grinding shoe (17) for a portable grinding machine is proposed which has a supporting plate (15) which performs the grinding movement and is equipped with suction channels for the purpose of dust extraction. The plate-like grinding shoe (17), which can be attached to said supporting plate (15), has connecting channels which lead on the one hand to the grinding surface (19, 20) and on the other hand to the suction channels. The grinding shoe (17) protrudes beyond the supporting plate (15) on at least one side, the connecting channels in the grinding shoe (17) reaching into the protruding region (18) and leading there to the grinding surface (19, 20). By virtue of this grinding shoe, grinding is possible even in recesses, gaps, interspaces and confined places, and dust extraction is also possible at these locations. <IMAGE>

Title: Step-by-step mechanism for a rotary drive
IPC: F16H31/00
Filed: 1988-06-06
Granted: 1989-11-16
Abstract: The invention relates to a step-by-step mechanism (1, 2, 3) for a rotary drive (1), with an escapement mechanism (2) for a ratchet wheel (11) driven by the rotary drive. The escapement mechanism (2) has two slotted links surrounding the ratchet wheel (11), namely a pawl link (15) with pawls (24a, 24b) and a tensioning link (14) which can be moved backward and forwards between two positions perpendicularly to the axis (A) of rotation of the rotary drive. The tensioning link (14) is displaced by cams (13) of the ratchet wheel or of a tensioning wheel (10) connected to the latter, while a retention and release device, e.g. in the form of a magnet (3), is provided for the pawl link (15). Both links are surrounded by an annular spring (25) which is deformed and tensioned by the tensioning link (14) and, in the respective position, exerts a force on the pawl link (15) towards the axis (A) of rotation of the rotary drive. <IMAGE>

Title: Thread-transport apparatus for textile machines
IPC: B65H51/10
Filed: 1988-06-15
Granted: 1989-08-24
Abstract: The invention relates to a thread-transport apparatus for textile machines, especially for the supply of the weft thread of weaving machines, preferably ribbon-weaving machines, with a thread take-up roller (17), against the circumference of which the thread (F) to be taken up is pressed by means of a counterpressure roller (19) or by means of a conveyor belt guided via a deflecting roller, to form an S-shaped thread run, and the rotational speed of which is adjustable continuously by means of an adjusting gear (4) arranged between the thread take-up roller (17) and a drive shaft (1) and having two regulating discs (6) non-rotatable relative to one another, but adjustable in the axial direction for the continuous variation of the effective diameter of their conical working surfaces (6a). In order to provide a thread-transport apparatus which, during operation, allows a continuous and highly sensitive variation in the take-up speed by means of the adjusting gear and generates the least possible mechanical load on the thread, the thread take-up roller (17) is connected directly to the adjusting gear (4), the regulating discs (5, 6) of which are driven via their conical working surfaces (5a, 6a) by a friction wheel (2) arranged fixedly in terms of rotation on the driveshaft (1). <IMAGE>

The centres of the intermediate gears lie on lines (1, 2) which go through the centre of the corresponding sun gear and are at right angles to the axis of the ring gear (19). USE/ADVANTAGE - The drive is partic. useful on twin screw extruders for transmitting high torque to two closely spaced shafts without introducing excessive bending moments.
Patent DE-4236950-C1 (DE)
Inventor: SOLZBACH ULRICH DR
IPC: H04N5/232
Filed: 1992-11-02
Granted: 1994-03-24
Abstract: A device (1) is used for processing and reproducing image sequences. A film projected by a film projector (2) is recorded by a positionable video camera (3). This device should allow details recognisable in a film, for example coronary vessel segments, which move for example because of heart muscle activity, to be reproduced in such a way that they seem to stand still to an observer and may thus be better recognised thanks to the integration faculty of the eye. A first individual image is stored by the video camera as reference image and the position of the relevant image details is compared to that of a subsequent image. When position deviations are present, a correction signal is generated which is used for driving motor-driven positioning drives (12, 12a) which correspondingly move the video camera (3) sideways. It is also possible to modify the distance from the film projector (2) in order to amplify sections of the image.
