IPC: B23B31/12
Filed: 1989-03-23
Abstract: A keyless chuck for a rotary tool comprises a chuck body  10  which is adapted to be coupled at its one end to a drive spindle  1  of a drive source and coupled at the other end to a tool bit  3  for establishing a driving connection from the drive source to the tool bit  3 . Relatively rotatable to the chuck body  10  is a sleeve ring  50  which is operatively connected to a set of gripping jaws  20  for tightening the gripping jaws  20  on the tool bit  3  upon being rotated in one direction and loosening the same upon being rotated in the opposite direction. A one-way clutch  90  is provided to rotatively fix the sleeve ring  50  to the chuck body  10  when the chuck body  10  is driven to rotate in the direction of turning the tool bit  3  reversely. A handle ring  30  is disposed around the sleeve ring  50  to be rotatable relative thereto within a limited extent such that it disengages said one-way clutch  90  when said handle ring  30  is rotated in one direction within said limited extent relative to said chuck body  10 , allowing said chuck body  10  to rotate freely from said sleeve ring  50  to loosen said gripping jaws  20 .

IPC: G06F3/12
Filed: 1989-04-27
Abstract: A page printer with an internal CPU (15), interrupt controller (9), and direct memory access controller (DMAC) (18) has a direct memory access (DMA) stopping circuit (18a) in the DMAC, the function of which is to stop DMA transfer in response to a DMA stop signal and restart it in response to a DMA restart signal. The DMA stop signal is generated by the interrupt controller (9) when it selects certain interrupt requests, such as communication interrupt requests, enabling the CPU (15) to service these requests promptly. The DMA restart signal is generated at the end of the interrupt service routine. This arrangement permits DMA transfers to be performed in burst mode, stopping only when urgent interrupt service is required. Burst-mode DMA improves the speed of operation of the printer.

Abstract: The anaesthetic 2-(difluoromethoxy)-1,1,1,2-tetrafluoroethane is prepared by reacting a novel intermediate CHCl₂OCHClCOCl with sulphur tetrafluoride. The anaesthetic isoflurane (CHF₂OCHClCF₃) is formed as a by-product. 
     Isoflurane itself is prepared by reacting another novel intermediate CHCl₂OCH₂COCl with sulphur tetrafluoride at an elevated temperature to form CHF₂OCH₂CF₃, and then photochemically chlorinating the resulting compound. 
     Isoflurane may be converted to 2-(difluoromethoxy)-1,1,1,2-­tetrafluoroethane. 
     The two intermediate compounds are coproduced by photochemically reacting CH₃OCH₂COCl with chlorine at a temperature of above minus 15°C.

Abstract: The invention relates to those hydrocyclones which, for instance due to their length, do not lend themselves to manufacture in a single piece but are divided up into sections, which until now have been connected to one another usually with the help of flanged joints. In accordance with the invention it is proposed that the sections (52, 58, 60, 62) of a cyclone (50) be executed in such a way that the end of a section (e.g. 58) fits internally into the following section (60) in the direction of the flow and projects for a small distance into it, with the joint being sealed, if necessary, by a gasket. The sections are held securely together by means of a previously disclosed eccentric lock (70) of the folding strap type, at least two of which are arranged at each joint. Cyclones constructed in accordance with the invention can be imparted with curved form in order to facilitate, for example, their arrangement in batteries, and in those cases in which permanently connected cyclones are preferred, the sections can be welded together without the risk of crack formation, thanks to the fact that the arrangement in accordance with the invention produces fillet joints between the sections.

Abstract: The invention relates to a device for accurately positioning an object, such as a mirror 3 used to precisely aim a laser. The invention uses kinematic principles to hold the object. Here a 2-2-2 kinematic bipod system is employed. The invention uses three actuators 5 to position the object. Each actuator acts as a bipod restricting the object in two of its six degrees of freedom. Each actuator has three degrees of freedom it can transmit to the object. The actuator can rotate on its single-axis flexure 7 so that the actuator can rotate on one axis relative to support 4. Each actuator has a two-axis coincident flexure 8 on one end for allowing the object to be moved in two rotational degrees of freedom and the roller sleeve 50 allows a third rotational degree of freedom. Each actuator is positioned circumferencially about the central coordinate axis of the object to be moved, 120 degrees apart. Each actuator is powered by a stepper motor 6 which drives the differential roller screw accurately, providing translational movement to the system in the shortest length possible.

Abstract: A digital phase-locked loop regenerates a carrier signal phase synchronised with a received ASK carrier signal. During periods when no carrier signal is present, the regenerated carrier coasts at the frequency of the most recently received signal, rather than trying to phase-look on noise. When the received signal amplitude exceeds a threshold (Vref), the output of a phase detector (56) is sampled (81) and integrated (62) and used to generate (64) a pulse whose width corresponds to the phase error. The phase error pulse controls a digital oscillator (66). When the received signal amplitude is below the threshold (Vref), the output of the phase detector (56) is not sampled, and the output of the integrator (62) remains constant at the most recently obtained value.

Abstract: Apparatus for monitoring the focusing condition of the writing light beam (46) impinging the writing surface (48) of a recording medium (50) which operates on the principal that, although for all practical purposes a light beam from a laser device is collimated, it is in fact very slightly divergent as it emerges from the laser with a focal resonator because of diffraction of the Gaussian intensity profile plane wave that exists between the laser resonator mirrors at the beam waist and from refraction as the output light traverses the thickness of the output mirror. Accordingly, since the beam exciting the laser tube (2) is slightly divergent, the reflected light from the video disc (50) even though small in intensity, is conversely (provided the system is in focus) convergent as it passes in reverse direction through the diverging lens (34) and on toward the output of the laser device and beyond to the conjugate point where it forms a real image of the source plane wave, thus eliminating the need for a relay lens. The present invention makes use of this slight divergence and convergence of the incident and reflected beams, respectively, at the exit end of the modulator, to effect monitoring of the focus condition of the writing beam.

Abstract: The invention relates to a tool holder for rotating tools, in particular circular saw blades, chipping tools etc. Tool holders for rotating tools having a quick-change clamping device are known, a hub part having a central bore being arranged on a drive shaft. Owing to the play between drive shaft and hub part needed for the tool-holder exchange, axial run-out and eccentricity occur. It is therefore proposed to provide in the hub part (3) close to the drive shaft (2) means (35, 36) for producing radial pressure. In addition, a device (25) which secures the tool holder (1) on the drive shaft (2) in the axial direction is to be present. The invention can be used for a large number of rotating tools. It is suitable in particular for circular saws. <IMAGE>

Abstract: Retroreflective elements, such as cube-corner elements or right triangular prisms containing cube-corners, are arranged on articles to define separation surfaces between the elements; in another embodiment, the elements are truncated cube-corners incorporating similar surfaces on the elements themselves. If the surfaces are transparent they will transmit light through the article, rendering it partially transparent and partially retroreflective. The surfaces may be flat or curved. Standard grooving techniques may be employed to construct the elements, using mold cutting tools having flattened or curved tips instead of V-shaped tips; alternatively, electroformed molds may be lapped to include the shape required to produce surfaces. The elements and surfaces may be embodied in sheeting materials or internally illuminated signs.
