Title: Improvements in or relating to machining of curved surfaces of turbine blades and other articles
Inventor: HYNES OSCAR ALWYN
IPC: B23Q1/54
Filed: 1953-08-18
Abstract: 763,067. Milling turbine-blades; chucks; tailstocks. NAPIER & SON, Ltd., D. Nov. 17, 1954 [Aug. 18, 1953], No. 22713/53. Class 83 (3). A machining-fixture for supporting a part, such as a turbine-blade, whilst milling a curved surface of two different radii, is carried by a base 1, Fig. 1, which may be secured to the work-slide of a horizontal milling-machine when shaping the outside of a turbine blade 4. A similar fixture is suitable for milling the inside surface of the blade on a vertical-spindle machine. Two uprights 2, 3 on the base support a dead-centre 17 and a work-carrier 6. The latter is bolted to a chuck 5 rotatable in bearings 7 in a block 8. A pinion 30 is integral with the inner end of the chuck 5. The block 8 is adjustable along a diametrical-slot on the face of a further rotatable carrier 9. The latter rotates in a bearing 10 about a main axis B. An adjustment screw 11 fixes the position of the headstock axis A at the required eccentricity to the main axis B. A two-speed reversible electric motor 20 drives, through pinions 21 and shaft 22 in the upright 3, an overload clutch 23. The latter drives gears 24, 25, the second of which is secured to a shaft 26 rotating within the carrier 9. The forward end of this shaft has a pinion 27 which engages a rack 31, Fig. 3, sliding in a diametral-groove in the block 8 parallel to the movement of the block. The rack engages both the pinion 27 and the pinion 30, Fig. 1, so that movement of the gear 25, with the carrier 9 stationary, will rotate the chuck 5 about the axis A. This movement, in conjunction with a milling-cutter 40, machines the radius C-D of the outside blade profile. By an arrangement of stops, the carrier 9 is next rotated about axis B, and relative rotation of the chuck about its own axis A ceases. The larger radius ED of the blade is thus machined without stopping the movement. Electric switchgear is included so that the operation is continuous and the motor reversed to return the blade to its initial position; in addition the machine-slide may be controlled or the speed of the motor may be changed. Tailstocks. The centre 17, Fig. 1, is mounted in a slide 16 which may be adjusted to give the same or a different eccentricity to that of the block 8 carrying the chuck 5. The slide 16 is carried by a member 14 rotatable in bearings 15 in the upright 2 about an axis in alignment with the axis B. Thus on first rotation of the work 4 about the axis A, the tail end rotates about the centre 17, but during the second operation at increased radius, the centre and its support rotate within the bearing 15.

Title: Apparatus for detecting an object by reflection of radiation
IPC: G01S17/04
Filed: 1971-04-19
Abstract: 1339955 Detecting objects photo-electrically BOFORS AB 19 April 1971 [2 March 1970] 22894/71 Heading G1A In an apparatus for detecting an object by reflecting radiation therefrom and wherein a transmitter 1 produces a pulsed radiation beam 8, 9 and a reference electrical output in phase with this beam, any radiation reflected from the object is detected by a receiver 2 including a radiation-responsive element 14 whose output is compared with regard to phase with the output from the transmitter. In one embodiment the pulsed light beam is provided by a light source 3 and a rotating perforated disc 4, and a photo-cell 16 receiving light direct therefrom produces the reference output. Alternatively a discharge tube or a light diode may be driven by a modulator which produces the reference output directly. Both the receiver output and the reference output are converted to square-wave form in respective amplifier/shapers 15, 17. The square wave outputs are compared in a logic unit 18 which produces an output only when the signals are out of phase. The amplifier/shaper 17 also produces at B a train of short pulses of twice the frequency of the pulse train generated at its reference output A. When an object is in the radiation path the square wave outputs 15, 17 are in phase, and hence logic unit 18 provides no output. In this case, counter 19 counts the short pulses B from shaper 17 to give an indication as long as the object remains in the radiation path. With no object in the radiation path the output from shaper 15 will comprise noise phases out of phase with the reference output. In this case, logic unit 18 provides an inhibit output to maintain counter 19 constantly at zero. The radiation used is preferably optical radiation of wavelength less than 10 Ám, but electromagnetic radiation of longer wavelength, or other radiation, may be employed. Two-bit counter 21 ensures that occasional noise pulses in the output from the photo-cells 14, 16 are not operative to re-set counter 19; only the unlikely coincidence of more than two pairs of each pulses will re-set the counter 19.

Abstract: 982,786. Stretching and shrinking films. GOODYEAR TIRE & RUBBER CO. June 11, 1963 [Sept. 5, 1962], No. 23171/63. Headings B5A and B5B. [Also in Division B8] A thermostretchable and thermoshrinkable film, adapted to be in an overall flat condition on a flat surface, has limited areas, over substantially the whole film area, stretched more than adjacent areas. The stretched areas, which extend into a different plane from the relatively unstretched areas, may surround, or may be surrounded by, the unstretched areas. The film, formed from, e,g. vinyl chloride/vinylidene chloride copolymer, polyethylene, polypropylene, nylon or rubber hydrochloride, may be made by stretching limited areas of an unstretched film, or by reducing or removing the stretch from limited areas of a stretched film. In one embodiment (Fig. 1), a film 1 rests on a screen 2 which is supported on a vacuum chamber 3. Heater 7, with heating elements 8, is lowered to a position sufficient to heat and soften the film. Portions of the film are pulled, by vacuum in chamber 3, through the screen, such that a patterned effect of adjacent stretched and unstretched areas is formed. In a continuous process, a screen belt is used (Fig. 2). Alternatively, the film 43 (Fig. 4), may be passed over a perforated drum 40 and heated over a part of the film path by heater 48. Vacuum is applied to a portion of the perforations 42 by means 51, the remainder of the perforations being covered. In a further embodiment (Fig. 7) a stretched film 60 is passed over a roller 62 bearing heated projections 63. The film shrinks where it contacts the projections causing the stretched portions of the film to pucker. Selective shrinkage may also be carried out by passing a stretched film 70 (Fig. 8) under a nozzle 72 from which drops of hot water are sprayed on to the film, which is dried at 74. The films are used in packaging (Division B8).
