Density separators. - A spiral separator for coal has a feeding shoot secured to the runway and of variable inclination to it so that the velocity of the material supplied may be controlled. In the form shown three spiral runways 11, 12, 13 are employed and are provided at their lower ends with adjustable division plates 14. These plates are pivoted to the runways and are simultaneously adjusted by the lever 14a which can be locked to the fixed plate 14d. A separate lever can be provided for each plate if desired. Feed shoots 15, 16, 17 are pivoted to the upper ends of the runways and are attached to a bar 18 linked to a lever 20 on a pivot 21. The inclination of the shoots may be varied by the manual operation of the link 22 which may then be locked to the post 25. The top shoot 15 has openings 26, 27 through which material passes to the runways 16, 17 respectively. The material is fed into a bin 30 with a discharge opening 34 the area of which is varied by a sliding gate 35 operated by a rod 38.

Title: Attenuation of radiation
Inventor: JONES OWEN CHARLES
IPC: G01J1/24
Filed: 1961-09-07
Abstract: 1,031,781. Optical apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 7,1962 [Sept. 7,1961], No. 32232/61. Heading G2J. [Also in Division G1] The apparatus employing a repetitive shutter of which the open to shut time ratio can be adjusted over a substantial range so as to reduce the average intensity of the radiation without reducing its amplitude, timing means are employed to compare the open and shut times of the shutter. As shown applied to a spectrophotometer, Fig. 1, for determining the transmission factor of a fitter 42, light from source 10 and monochromator 12 is directed alternately along patches 14, 16, to a null detector 18 and radiator system 20, 22, by means of mirrors 24-27 of 2hich 24, 27, are oscillated by a switching device 28. Shutters 30, 31, in light paths 14, 16, respectively are controlled by triggering circuits 34, 35, a gating circuit 32 allowing the shutters to operate alternately for a fixed time interval eq. 1/ 40  second. The shutter 30 opens to deliver pulses of fixed amplitude and duration eg. 10<SP>-7</SP> second at a fixed recurrence frequency of eg. 1 Mc/s, determined by triggering from stable oscillator 34. Shutter 31 is similar, but is triggered by a variable oscillator 35 having a working range eg. 1 Mc/s to 100 c/s. Initially indicator 22 is read without filter 42 in place and the frequency of shutter 31 altered until a null reading is obtained on indicator 22, a small fraction of the light in path 16 being directed by beam-splitter 40 to a detector 38 operating a counter 36. Filter 42 is then inserted in path 14 and and shutter 31 again altered to obtain a null reading on indicator 22, the pulses reaching detector 38 being counted at 44. Comparison of the readings of counters 36, 44, gives the transmission ratio of the filter 42. In another embodiment, Fig. 2 (not shown,) a high frequency shutter 130 is placed in the common optical path between monochromator 112 and mirror 124 and a low frequency shutter 131, synchronised with the beam switching device 128 is placed in the reference beam 116. In a further embodiment, Fig. 3 (not shown), a variable sector disc shutter 231 of intermediate frequency eq. 500 c/s is placed in the reference beam 216 and a detector 238 opens a gating circuit 246 to allow pulses to flow from a high frequency oscillator 248 to the appropriate counter 236, 244, when the shutter 231 is open.

In a screw and half-nut mechanism, lubricant under pressure is supplied to the side faces of some of the threads through valve means operated by the rotation of the screw so that only those openings which are covered by the nut face receive lubricant. As shown, a screw is in two parts 2, 4 which are urged apart by fluid under pressure to compensate for inaccuracies of the pitch of the nut or rack. The screw is rotatably mounted in bearings 5 in frame 11, and rotates relatively to a fixed pintle 3 which is connected to a source 12 of pressurized lubricating oil through restrictors 8, 9. The pintle 3 has a gallery 17 associated with each nut part and this gallery 17 co-operates with radial bores 14 to supply oil under pressure to bores 10 in the faces of the screw only when the bores 10 are in contact with a nut 13. Arcuate pockets 16 are provided in the surfaces of the nut teeth. Alternatively, the valve means may comprise co-operating valve ports which could be provided between an end face 21 of the screw and a co-operating fixed end plate.

Abstract: 742,914. Variable speed gear. MANGIN, R. Nov. 23, 1953 [Nov. 27, 1952], No. 32483/53. Class 80(2) An automatically variable ratio gear, for vehicles, &c., between driving and driven shafts 1, 7, comprises a differential, consisting in the form shown of an internally toothed annulus 6, stepped planet gears 10 in a carrier 11, and a sun gear 12, drive passing through a torque responsive coupling 2 and an auxiliary shaft 4 to the annulus 6 via a gear 5 and through expanding pulley 14...17, 21...24 and V-belts to the sun gear, while the planet carrier is fast on the driven shaft 7, the axial positions of the movable flanges 15, 17 and 21, 23 of the expanding pulleys, and hence the velocity ratio, being determined by the force produced by the torque responsive coupling 2 and by an opposing force produced by centrifugal means 37. The sizes of the annulus 6, planets 10 and sun 12 are so proportioned that the planet carrier rotates with an angular velocity which is the algebraic mean of the angular velocities of the sun and annulus. The torque responsive coupling 2 consists of a pinion on the driving shaft having helical teeth engaging a sleeve 3 acting as a nut. The auxiliary shaft 4 is hollow and can rotate on the driving shaft. The centrifugal means comprises balls 37 engaging surfaces 39, 41 on the pulley flanges 15, 16. These surfaces are arcs of radii such that, for a given angular velocity of the driving shaft, the axial component of the force acting between the balls and surfaces, and tending to separate the pulley flanges, is constant, irrespective of the radial position of the balls. The movable pulley flanges 15, 17 and 21, 23 are connected to each other by rods 18, 25, respectively. The movements of the two sets of pulley flanges are co-ordinated by a member 28 and bearings 19, 27 connected to the movable flanges by the rods 18, 25, so that separation of the flanges 14, 15 is accompanied by a closing movement of the flanges 21, 22, &c. The flange member 28 has trunnions 29 rotatable in fork members 34 on a rocking shaft carrying levers 36. A removable stop can be engaged by one of the levers 36, in which position no drive passes to the driven shaft 7; when the lever moves away from the stop, forward drive is obtained. By taking away the stop and moving the levers 36 by hand, reverse is obtained.
