Abstract: 295,732. Hall, J. Feb. 18, 1927. Drilling brush stocks.-The machine has two work-holding cradles 113, Figs. 1 and 4, each adapted to hold a brush stock, and to which positive synchronized movements are given, to present the stocks held therein to the drilling and knot-inserting tools 17, 319, respectively, so that as a hole in a drilled stock in one holder is filled a, hole is drilled in a corresponding position in the other stock, the holes being drilled at varying angles and positions but all to a uniform depth irrespective of the shape of the stock. Each cradle 113 is pivotally mounted, to permit the stocks being moved vertically across the tools 17, 319 into positions corresponding to the various of holes, in trunnions 116 which are adapted to slide towards and away from these tools under spring-action in slots in one of a. pair of similar, connected, heads 97, 98, adapted to pivot, to move the stocks horizontally across the tools 17, 319 into positions corresponding to the holes in the various rows, about vertical pins 95, 96 respectively, carried by slides 93, 94 on a base plate 90 secured to a reciprocatory main frame supported on a table 87 carried by the machine framing. The cradles 113 receive their tilting movements and the heads 97, 98 their pivoting movements, through mechanism operated by cams 220. 195, respectively, on a cam-shaft 59, which is rotated step-by-step through pawl - and - ratchet gearing and worm and wormwheel reduction gearing from a main shaft 13, the machine being automatically stopped. for the removal of the stocks from their holders, at each revolution of the cam-shaft by the withdrawal of a clutchmember. The cam 195 is oval shaped and moves the connected heads 97, 98 about their pivots 95, 96, tc position the stocks in longitudinal position relatively to the tools, movement being given to the heads by rolls 151, which engage cam grooves 150 shaped to move the heads by an amount to compensate for the radial movements of the cradles as the heads pivot about their pins 95, 96, and the curvature of the stocks, to ensure the holes being drilled to a uniform depth. Similar compensating movement is given to the cradle 113, as it is tilted by the action of the stepped cam 220 through a slide 216, Fig. 18, levers 197, 196, a plate 205, Figs. 1 and 18, and levers 134, 214 and finally by connecting-rods 131, by shaped cam surfaces 119 on the cradles bearing against rollers 120 on the heads 97, 98, to ensure drilling to a uniform depth. An adjustable anvil 141 at the back of each cradle supports the stocks during the drilling and filing operations, the cradles being locked in position during these operations. The main slide 88 is reciprocated by an eccentric 52 on the main shaft 13 which also reciprocates the borer and knot inserting tools 17, 319.

Title: Improvements in or relating to control apparatus for sluice and like valves
IPC: F16K31/122
Filed: 1940-03-26
Abstract: 537,449. Fluid-actuated valves. COCKBURNS, Ltd., RODGER, J., and GRANT, T. March 26, 1940, No. 5395. [Class 135] A sluice or like valve adapted to be closed quickly in an emergency is actuated by two pistons, one controlled by a relay valve itself controlled by one or more manually operable remote control valves and the other piped to one or more remote hydraulic telemotor transmitters. As shown the valve spindle 6 is directly secured to the emergency closing piston 4 working in a cylinder 3 and to the telemotor piston 8 working in a cylinder 9. The cylinder 9 is coupled by pipes 19, 20 with a transmitter 7 comprising a piston working in a cylinder 11 provided with a bye-pass normally closed by a valve 18. This piston is reciprocated by a hand operated nut rotatably mounted in a bridge 16 supported by pillars 17 and engaging a screw-thread on the piston rod. An overhead make-up tank 21 is connected to the two ends of the cylinder 9 by pipes fitted with non-return and relief valves. A spring-loaded piston 22 working in a cylinder 23 adjacent the cylinder 9 is adapted, when moved by fluid pressure admitted through a valve 33 actuated by a hand lever 34, to open a cock connecting the two ends of the cylinder 9. Continued movement of this piston takes up the lost-motion 29<SP>1</SP> 30 and opens an exhaust valve to release the pressure below the piston 4 and permit the pressure acting above the piston to close the sluice valve. A nut 38 engaging a thread 6<SP>1</SP> on the spindle 6 is rotatably mounted in a bridge 39 slidably mounted on pillars 10 connecting the cylinders 3 and 9. When it is desired to actuate the sluice valve manually the bridge is anchored in position by pins 40 inserted through holes 40<SP>1</SP> into engagement with an appropriate pair of notches 41 in the pillars and the nut 38 rotated by a suitable tool. The frame supporting the valve members 1 is provided with a hollow guide spindle 43 working through a stuffing box 44 in a cover 45. The cover 45 is formed with a spigot 46 terminating in an annular knife-edge 47 adapted, when the valve is fuily open, to engage notches 48 in the valve members to prevent these elements fluttering or vibrating. A. pin 49 with a manipulating part 51 has a screwthreaded engagement with the spindle 43 and is adapted to be moved inwardly to pass through holes 53 in the usual telescopic guides in the valve members and so prevent them moving apart under the influence of springs 55. According to the Provisional Specification flutter may be prevented in the open position of the valve by a fixed pin passing through holes in the telescopic guides. The telemotor transmitter may be fitted with pressure operated indicators to indicate the position of the valve.

Title: Process and apparatus for determining the spectral composition of luminous radiation
Inventor: ROUSSOPOULOS PAUL
IPC: G01N21/47
Filed: 1965-02-05
Abstract: 1,063,764. Photo-electric measurement of diffuse reflectivity. L'OREAL. Feb. 5, 1965 [Feb. 5, 1964 No. 5147/65. Heading G1A. To measure the diffuse reflectivity of a substance in relation to a standard, light from a lamp 1 is directed by lens 2 and mirrors 14 and 15 to partially reflecting mirror 4. The reflected and transmitted light beams, when able to pass through one of apertures 12 in motor-driven drum shutter 11, fall respectively on test sample 5 and standard substance 6. Diffusely reflected light from these elements travels back through the drum aperture to the mirror 4 and from thence a fixed proportion is directed by mirror 16 and lens 7 on to the cathode of photo-multiplier 8. The output signal of the detector 8 is preferably applied, after amplification, to a cathode-ray oscilloscope. As the drum rotates the reference and measuring beams are interrupted alternately to give a stepped trace on the oscilloscope. Movement of the disc 9, which is a variable transmissive attenuator in the reference beam path, enables the trace to be made linear when the angular position of the attenuator can be read off as an indication of the diffuse reflectivity of the sample relative to the standard. A filter 3 may be introduced into the system so that measurements may be made for any desired light wavelength. By inserting an additional reflector in one of the beam paths the two images of a portion of the lamp filament formed via the two beam paths can be directly superposed.

Filed: 1953-02-26
Abstract: 731,558. Heavy-ion-beam tubes. BENDIX AVIATION CORPORATION. Feb. 26, 1953, No. 5451/53. Class 39 (1). In a mass spectrometer of the time-of-flight type, the ions are successively subjected along their path of travel from the ion source to the ion collector to a moderate accelerating force, a low or zero accelerating force and a relatively high accelerating force. The object is to obtain a relatively sharp delineation between the ions of different masses. In the apparatus shown, the ion source consists of a slotted electrode 28 and a backing electrode 26, and gas molecules introduced at 34, are ionized by means of an electron beam generated by a gun system 10, 12, 16, 18 and directed to a collector electrode 24. When a maximum concentration of ions is obtained, the electron beam is cut off and the ions are ejected in a bunch through the electrode 28, and through further slotted electrodes 42 and 46, and then travel towards the collector plate 50. An accelerating field of moderate intensity is established between electrodes 26 and 28, of low or zero intensity between electrodes 28 and 42 and of relatively high intensity between electrodes 42 and 46 by the application of voltage pulses. For example, electrode 26 may be at 200 volts positive, electrodes 28 and 42 at 150 volts positive and electrode 46 at ground potential. Collector plate 50 is at negative potential. Specifications 713,993 and 727,683 are referred to.
