Title: Improvements in or relating to methods and means for testing a translucent fluid substance
IPC: G01J3/42
Filed: 1951-04-06
Abstract: 710,867. Spectroscopes. DALY, E. F., and UNICAN INSTRUMENTS (CAMBRIDGE), Ltd. April 2, 1952 [April 6, 1951], No. 8032/51. Class 97(1) [Also in Group XL(b)] In order to ascertain the component substances of a translucent fluid mixture its absorption spectrum is compared continuously with that of a reference fluid mixture of known composition which is adjusted to give exactly the same absorption spectrum, by passing light through each fluid and alternately through a mono-chromator and photocell, the outputs being alternately displayed on a cathode-ray tube, whereby any differences in the spectra may be determined and eliminated. Two beams of visible or infra-red radiation from lamp 1, Fig. 1, are focused by concave mirrors 4, 5 on two compartments. 6, 7 each comprising four cells 10 (described below), the cells of compartment 6 containing the test specimen, and those of compartment 7 containing the reference fluid. The beams are then refocused by mirrors 11, 12 on an oscillating mirror 14 serving as an optical switch, which directs the beams alternately via concave mirror 17 through a mono-chromator 21, having a scanning mirror 56, Fig. 4, attached to a steel bar 58 carrying two windings 59, 60 and attached by phosphor-bronze strips 58a to a rigid frame 58b. Coil 60 is fed with a 10 c/s sawtooth voltage wave from a generator 62, through a gain control 65 and cathode-follower 92 with negative feedback via coil 59 and amplifier 63. Thus by providing a magnetic field around coils 59, 60 the bar 58 and mirror 56 oscillate at 10 c/s, the amplitude of swing being controlled by gain control 65, and the mean angular position being controlled by a spring-loaded finger 66, attached to the bottom support of bar 58, pressed against an adjustable cam 68. The light emerging from the monochromator 21 is directed by mirror 72 to photo-electric device 74 or 75, whose output thus consists of a D.C. voltage with a ripple A.C. at the frequency of the optical switch (1500 c/s), which after amplifying and filtering at 80, 81, 82 has an amplitude equal to the difference between the absorption of the two paths, and is shown on a cathode-ray oscilloscope 85. The cells 10, Fig. 2, are mounted on slides 25 having a fused silica window 24, and which run in grooves 26 in the sides of the compartments. A threaded cup 28 is secured to the slide 25, and holds a ring 29 carrying a plate 30 supporting another fused silica window 23, the distance between the windows being adjustable by screwing ring 29, and being indicated. by an external ring 32 on the wall 33 of cup 28. The optical switch comprises the vibrating mirror 14 mounted on a soft iron armature 39, Fig. 3, in the centre of a torsion bar 15, between the tapered poles 43, 44 of an electromagnet fed with the resonant frequency of the system by an oscillator 45, which is maintained at that frequency by a pick-up coil 50 associated with the torsion bar 15 and feeding back into the oscillator 45.

Abstract: 758,758. Fluid bearings; lubricating. MASCHINENFABRIK ANDRITZ AKT.-GES. March 19, 1954, No. 8052/54. Classes 12 (1) and 12 (3). In a fluid bearing for a shaft 10 mounted in a bush 9, automatic suction of lubricant from a chamber 12 is effected through a supply channel 14. The channel 14 is located in the running surface of the bearing in a region of negative pressure extending 25 to 180 degrees beyond the generatrix which is located in the direction of the load on the bearing and extends “-length each side of a mid-length plane. A similar channel 14<SP>1</SP>, Fig. 7, may be disposed on the opposite side of the bearing to act as an outflow channel, or, when the shaft 10 rotates in the opposite direction, as a supply channel. For a vertical shaft 16, Figs. 8 and 9, three uniformly distributed channels 14, 141 and 14<SP>11</SP> are employed. Non-return valves may be incorporated in the channels.

Title: Improvements relating to multi-spindle automatic machine tools
Inventor: RYDER RICHARD DUDLEY GEORGE
IPC: B23Q11/00

Abstract: 781,658. Lathe details. RYDER & SON, Ltd., T. Jan. 9, 1956 [March 21, 1955], No. 8130/55. Class 83 (3). Indexing-means for the work-turret of a multi-spindle automatic-lathe comprises an electric-motor j, Fig. 1, which drives the turret c in the forward indexing-direction until it reaches a point slightly beyond the next tooling- station, whereupon the turret is stopped by switching-off the electric-motor and by the operation of a hydraulic-motor v which drives the turret in the reverse direction until it is arrested by a locating-catch h, against which it is pressed hydraulically until the next forward-movement of the table. The turret is rotated by gearing from the motor j and shaft k. The hydraulic-motor is connected to the latter and a solenoid-controlled valve u is opened to permit the hydraulic-motor to run freely when the electric-motor is driving. On approaching a new index-position the locating- catch h springs into one of the recesses g, the electric-motor is automatically stopped, and the hydraulic-motor started to reverse the rotation of shaft k and bring the edge of the locating-recess hard against the catch h. Pressure-fluid continues to flow to the motor v and a pressure-relief-valve is incorporated to prevent build-up of pressure. A further fluidpressure-motor w then operates to move a piston y in a cylinder x to operate a wedgecatch i, which holds the turret rigidly during working. Brakes. A driving-shaft o of the gearing may be provided with a one-way wedging braking-device 12, 13, Fig. 4, operated by a solenoid 11 which helps to bring the turret to rest on cessation of the electric-motor drive, but which has no effect on the fluid-motor drive.

A connecting element, e.g. for securing the module to a wall of a furnace, may be secured to the substrate and protected from the adhesive during the application of the adhesive to the substrate. A protective wrapper 20 may be applied to and folded around the module. The substrate may be an insulation block and the adhesive a grout applied as a substantially viscous liquid by lowering the block by movement of a fixture carrying the block to immerse the block sufficiently into a pool of grout to coat one side surface and substantially all of the edge surfaces of the block with the grout. A plurality of edge battens 10, 18 of fibrous insulation material may be bonded to the module by means of adhesive. Battens 16 may be produced by imparting incremental linear movement to the stack of sheets of fibrous insulation material and severing a portion of the stack at each increment of movement of the stack, the pad formed being positioned in relation to the substrate using a fixture means comprising impaling means disposed for receiving and retaining relationship within the various layers and ejector means by which the impaling means are separated from the pad.
