Title: Improvements in or relating to Methods Of and Devices For The Thermal Processing of Material By Means Of Laser Beams
IPC: B23K26/03
Filed: 1966-05-20
Abstract: 1,153,282. Removing metal or welding by fusion. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 May, 1966 [25 May, 1965], No. 22582/66. Headings B3R and B3V. [Also in Divisions C1, G1 and H1] In performing a thermal process, such as evaporating, welding or cutting glass at a specified point on an object by means of a laser beam, either the same beam at low intensity or a low intensity beam from a second laser first, scans the object in search of the point, a photo-cell viewing the object detects the beam's arrival at the point and causes the scanning to stop and starts the thermal process by either increasing the intensity of the scanning laser beam or by switching on a higher powered laser. The scanning laser beam is deflected over the object by a digitally controlled electro-optic device employing a Kerr cell and, if a second laser is used for the thermal process the beam from it is directed at the specific point either by the electro-optic device used for the scanning beam or by a second simultaneously operated electrooptic device. The processing laser beam may be given a particular cross-sectional shape by a mask, which is selected from a number of masks by initially deflecting the beam to pass through that mask. The beam-may scan across the mask if the mask area is larger than the beam crosssection. In an arrangement shown in Fig. 4 for welding two wires D at their cross-over point, a scanning beam from laser LT is scanned in raster fashion across the wires by an electrooptic deflection device A 3 . A photo-cell supplies a pulse each time the scan crosses a wire to a logic circuit Sch which stops the scanning and switches on a second processing laser LL when the cross-over point is reached.

Abstract: 697,297. Friction clutches. KREIS, F., and S.I.B.A. SOC. ITALIANA BREVETTI AUTOMOBILISTICI AR.L. Sept. 14, 1950 [March 6, 1950], No. 22616/50. Class 80 (ii). A clutch for automatically connecting a speed stage in a variable speed gear is engaged centrifugally and disengaged by torque responsive means. The centrifugal sector weights 1 are mounted on the driven half of the clutch which is rotated, prior to engagement of the clutch, from the driven end of the gear. The clutch driving shaft 9 carries clutch plates 7 engaged by plates on a clutch half 5 which is axially moved by inclined surfaces on the weights 1. The weights are retained by a tie spring and are mounted on bolts 13 which engage recesses 15, 16, Fig. 4, in relatively rotatable overlapping discs 2, 3 and thereby rotatively couple the two discs. The disc 2 is secured to the driven shaft 4 while the overlapping disc 3 is slidably connected to the clutch half 5. At low speeds the tie spring holds the bolts 13 fully in the recesses 15 and as the speed of the shaft 4 increases the bolts 13 are centrifugally moved out of the recesses 15 to the position shown in Fig. 4 and the clutch is engaged. Should the torque exceed a predetermined amount, however, the discs 2, 3 undergo a slight relative rotation and the bolts 13 are forced back into the recesses 15, thereby disengaging the clutch.

Filed: 1931-08-11
Abstract: <PICT:0380566/IV/1> A centrifugal box or pot spinning-machine is provided with bobbin-winding spindles arranged above the boxes, the viscose for forming the threads wound in the boxes and on the bobbins being supplied from a common source and passing through a common coagulating bath whereby centrifugal box spinning and bobbin spinning are simultaneously carried out and increased production is obtained without duplication of the supply conduits for the viscose and acid. Separate jets are provided for each box and each bobbin and a separate pump and filter may be provided for each jet, or one pump may supply a jet for a box and a jet for a bobbin either through two separate filters or through a single filter.  A pair of jets may be supplied by a common pump through a common filter and a common rounder end, and each may be carried on a branch from the rounder end or both may be supported in an enlarged holder on the rounder end, Figs. 5, 6 (not shown).  The invention may be applied to existing centrifugal machines without altering the gauges or other dimensions. As shown, bobbin spindles H are mounted above centrifugal boxes A, the viscose passing from jets c to the boxes and from jets c<1> to the bobbins h<1>.  The boxes are driven by independent motors a and the spindles by a motor K through a shaft k<1>, variable gear k<2>, a sprocket chain k<4> and bevel gearing h<2>.  The filaments are laid on the bobbins by a rod L reciprocated by levers and links L<3>, L<2>, L<1>, L<4> from a lever L<5> which is oscillated by a cam M engaging two runners l<6> thereon.  If bobbins with conical ends are desired, the necessary reduction in traverse is obtained by connecting the link L<4> to a screwed rod l<4> in the lever L<5> which is rotated to vary the effective radius by means of bevel gear l<3> driven by a ratchet wheel M<1> operated by a pawl carried by the lever L<5>.  The Provisional Specification describes also the application of the invention to a machine having double the number of pots or boxes of approximately half the usual diameter; the mounting of the bobbin spindles directly on the godet shafts; and the use of ordinary jets, the filaments issuing therefrom being divided to form independent threads, and of jets having two separate sets of holes.

Abstract: 1467505 Throttling in hydraulic dampers; valves DAIMLER-BENZ AG 22 May 1974 [26 May 1973] 22939/74 Headings F2S and F2V An hydraulic damper comprises two working chambers 4, 5 with valves 8, 12 between them, and a path 24, 25, 39, 38, 40, 26, 27 by-passing the valves, the cross-section of the by-pass being reduced automatically on an increase in pressure in either chamber by movement of a spring biased valve piston 34 which has a face subject to the pressure in one chamber, and a face subject to the pressure in the other chamber. As shown the valve piston 34 is also responsive to a control pressure dependent on vehicle loading, supplied via a passage 56 in the piston rod 2 to control chamber 55. The pressure in working chamber 4 is communicated to control chamber 49, and that in working chamber 5 to control chamber 52. Other faces of the valve piston 34 are exposed to atmospheric pressure. The control pressures in chambers 49 and 52 cause the valve piston 34 to move in dependence on the oscillation velocity of the main piston 3. As the piston 34 moves, the control edge 58 of a groove 38 in the piston constricts the parts 39, 40. A spring 41 biases the piston 34 to the position shown where the parts 39, 40 are not constricted. Considering operation for a given vehicle loading, with increasing oscillation velocity the bypass becomes more and more restricted and then the valves 8, 12 open.

Title: Improvements in or relating to apparatus for delivering measured quantities of liquid
IPC: G01F11/02
Filed: 1936-08-24
Abstract: 475,682. Delivering measured quantities of liquids. PIEL, A. L. Aug. 24, 1936, No. 23194. Convention date, Aug. 23, 1935. [Class 106 (v)] In apparatus for delivering measured quantities of liquids comprising a measuring chamber 4 having a valve 3 through which liquid may be discharged or drawn into the chamber by suction through a pipe 6, the measuring chamber is provided with a capacity adjusting plunger carried by a vertically adjustable tube 12 enclosing part of the -suction pipe and including a float chamber 13 and a valve 14 adapted to be actuated by the float 15 to close the suction pipe when the measuring chamber has been filled. The measuring chamber comprises a glass cylinder clamped between upper and lower members 9, 10. The upper member serves as a guide for the tube 12 and houses a pinion 17 engaging with a rack formed on the tube and adapted to be operated by a regulating wheel 18 having markings showing the capacity of the chamber. Rotation of the valve 3 operates a counting mechanism. The Specification as open to inspection under Sect. 91 comprises several modifications. In one form, the pipe 6 for connection to suction leads off from the side of a tube enclosing the tube 12 and liquid can be drawn into the measuring chamber only when the plunger is in such a position that one of a number of holes in the tube 12 is opposite the pipe 6. Alternatively, the suction connection is closed by a locking rod unless the rod is pressed by a spring into one of a number of holes in the wheel 18. In another form of apparatus, the plunger may be replaced by a combined inlet and overflow pipe 45 having a funnel shape top 44, Fig. 10 (Cancelled), connected with the float chamber 49 and the adjustable suction tube 48. In operation the height of the pipe 45 is adjusted by the regulating wheel 56 and liquid is drawn into the measuring chamber until a valve 50 is closed by the float 51. At this moment the chamber is placed open to atmosphere, the liquid above the funnel 44 returns to the reservoir and the remaining quantity can be drawn off by the valve 60. This subjectmatter does not appear in the Specification as accepted.
