IPC: B60S1/68
Filed: 1947-11-11
Abstract: 622,362. Wheel scrapers. CARLTON, W. C. Nov. 11, 1947, No. 29958. [Class 108 (ii)] A tyre protecting and preserving device comprising an extractor or deflector blade and supporting means therefor, has means whereby as the tyre surface wears away, the blade is automatically moved towards the tyre surface in such a manner as to maintain the setting of the blade, relative to the tyre surface. In the arrangement shown in Fig. 1, an extractor or deflector blade 21 secured to or formed integral with flanges 20, is urged towards the tyre 2 by means of a spring-loaded linkage arrangement comprising links 17 and twist springs 22 carried by a bracket 12. The bracket 12 is carried by a channel member 9 which is rigidly secured to the wheel suspension system. The lengths of the links 17 are determined in accordance with the relation between maximum tyre diameter and the reduction thereof due to wear, so as to give the blade angular or parallel motion as required to maintain its setting tangential to the tyre surface. In a modification, Figs. 4 and 5, the setting of the blade 21 is maintained by a " lazy tong '' linkage arrangement carried on a spindle 27 rigidly secured to an upright 35. The blade is given parallel motion under the action of tension springs 34. In another arrangement, Figs. 6 and 7, the blade 21 is supported by helically wound steel spring wire arms 36, each provided with vibration damping means comprising a flexible multi-strand cable 40. Secured to the wire arms at each end thereof in thimbles 37. The arms are supported by a bracket bar 39 extending from a channel member 9 attached to the wheel suspension. The blade carries transverse skids 42 to permit the blade to be advanced automatically towards the tyre surface without alteration in any pre-set angular and offset position of the blade relative to the tyre surface. In a modification, Fig. 8 (not shown), a double acting extractor blade provided with a skid device has its inner surface made concave to enable its operative edges to be brought sufficiently close to the tyre surface. Double acting blades may be used with any of the arrangements, Figs. 1-7 above. Specification 622,361 is referred to.

Title: Improvements in or relating to carrier frequency telegraph systems
Inventor: CHITTLEBURGH WILLIAM FRANCIS S
IPC: H04L5/06
Filed: 1959-09-03
Abstract: 897,980. Multiplex transmission systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 3, 1959, No. 30037/59. Addition to 620,715. Class 40 (4). [Also in Groups XL (b) and XL (c)] A multi-channel carrier frequency telegraph modulation system for operation over a communication path which is liable to introduce a change in the mean carrier frequency of each channel includes means at the transmitting end for the transmission with the telegraph signals of a pilot wave having a frequency outside the band of frequencies occupied by the telegraph signals but within the frequency band of the carrier channel, and at the receiving end means for correcting the change in the mean carrier frequency for each channel by the received pilot wave for introducing a frequencyshift which is substantially equal and opposite to the frequency-shift introduced by said communication path whereby the last mentioned frequency-shift is substantially neutralized. In the diagrammatic arrangement of Fig. 1, the modulated output of a transmitter including the pilot frequency is received over a line 1, passes to a carrier telephone receiving system 7, and after passage through a frequency corrector 8 is applied to filters 9 leading to associated telegraph demodulators 10. The corrector 8, Fig. 2, included between the system 7 and the filter 9 comprises a modulator 13 to which is applied the frequency #1 from an oscillator 14 and, for example, f + df, where f is one of the telegraph frequencies and df is the frequency shift introduced by the telephone channel and a filter 15 passes the lower side band #1 - (#+d#) to the demodulator 20. A filter 22 passes the received pilot frequency F + df to a modulator 23 fed with the frequency #1 from the oscillator 14. The lower side-band, i.e. #1 - (F + df) from the modulator 23 is selected by a filter 16 and passed to a modulator 17 which receives the pilot frequency F from the oscillator 18 and a filter 19 passes the upper side band i.e. #1 - df which is applied as the second input to the demodulator 20. A filter 21 selects from the output of the demodulator 20 the lower side band #1 - d# - [#1 - (f + df] i.e., f which is independent of the frequency shift df and is passed by a filter 21 to a terminal 12 leading to the telegraph channel filters.

Title: Packing for fractionating columns and the like
IPC: B01D59/04
Filed: 1935-11-01
Abstract: 451,014. Treating liquids with gases. STEDMAN, D. F., 70, Stanley Avenue, Ottawa, Canada. Nov. 1, 1935, No. 30195. [Class 55 (ii)] Packing for fractionating columns comprises capillary sheet material with capillary openings which seal with liquid and allow it to flow through, the material 1 dividing the column into uniformly shaped and regularly disposed enclosed cells with openings 2 smaller than the diameter of a cell but larger than will seal with liquid which connect each cell directly with at least two higher and two lower cells. The sheet material may be of wire gauze with mesh openings of À01 or .02 inches diameter, fabric, asbestos, glass fibre, slag wool or of moulded material. It may be corrugated in three directions at 120 to each other to provide rows of pyramids with apices 4 and depressed pyramids 5 resting on the apices of the next lower layer, so that each opening 2 receives vapour from three lower roughly cubical cells. The pyramids and openings in adjacent rows are .staggered. The sheets may be corrugated in one direction only and placed together with their corrugations parallel vertically or horizontally in the tower. The corrugations may be at right angles as in Fig. 4, the sheets being placed horizontally with a separator sheet 9 with openings 10 between the sheets. The material may be held corrugated by longitudinal bars resting on lugs or in recesses in the column walls. The sheets in Fig. 5 are flat and are spaced by strips 11 of glass or enamelled iron, those in one layer being placed at right angles to those in adjacent layers. The openings 2 in the lowermost layer are larger to increase drainage, and the vapour may be led thereto by vertical capillary surfaces depending from this layer and leading liquid from the openings. Heating or cooling means may be inserted in the tower, and the layer immediately above is formed similarly with vertical surfaces.

Title: Improvements in spring suspension for vehicles
IPC: B60G11/08
Filed: 1920-10-26
Abstract: 153,019. Hassler, R. H. Oct. 2, 1915, [Convention date]. Springs, arrangement of; frame construction.- In a spring suspension for vehicles, a supplementary leaf spring 14 is pivoted to a support on the axle 7, is connected to an end of the vehicle spring 23 with its free end supported in suspension above the vehicle spring, and is formed to increase its range of contact with its means for suspension above the vehicle spring as the load is increased. As shown for a motor-vehicle, the spring 14 has its leaves of different lengths with the outer ends even and bolted to a bracket 16 pivoted to a head 10 on an extension 8 of the axle 7. The leaves are further bound together by clips 21, 22<1>, the clip 21 being connected to the bracket and by links 22 to the end of the semi-elliptic vehicle spring 23. This spring is secured to the underside of a tubular portion 13 of a transverse casting 12 forming part of the frame which comprises also longitudinal channel bars 11. Under normal load, the inner end of each spring 14 rides on the bottom plate of the front 13 as shown, but under overload the springs 14 are straightened out until about one fourth of their length is in contact with the bottom plate and the stiffer portions of the springs are brought into play. In this position, stop-lugs 19, 20 on a cross-bar of the bracket 16 and the head 10 respectively are apart, but on the rebound these lugs contact and limit the upward swing of each spring 14 causing its inner portion to contact with the outer end of the bottom plate of the part 13 and damp the rebound. The front casting 12 forms part of the engine support and has a bearing 24 for the engine shaft 25.

Title: Improvements in or relating to film guide release mechanisms for motion picture projector take-up reels
IPC: G03B21/32
Filed: 1931-11-02
Abstract: 379,142. Kinematograph projectors. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, New York, U.S.A.- (Assignees of May, R. P. ; Woodbury, New Jersey, U.S.A.) Nov. 2, 1931, No. 30308. Convention date, Dec. 15, 1930. [Class 97 (i).] In a film guide release mechanism for takeup reels of the self threading type, the peripheral speed of the take-up reel is greater than the linear speed of the film threaded into the apparatus, and the film guide is released by retardation of a film-driving element relative to the driving mechanism of the element. As shown a stationary guide 16 conducts the film towards the lower guide 17, which co-operates with the guide 15 to conduct the film towards the spool 13, and which is pivoted at 19 and operated by a link 21 so that clockwise rotation of the guide 15 effects counter clockwise rotation of the guide 17. The shaft 25 of the guide 15 carries a latch 27 comprising a detent 29 which causes the trigger 33 to hold the guides 15 and 17 in threading position. Keyed to the sprocket shaft 39 is a flywheel 43 loosely secured to the face of which by the screws 51 is a plate 49, attached to which is a gear 45 through which the mechanism is driven. The plate 49 drives the flywheel 43 by springs 53 connected to screws 54 in the flywheel, and to the square portion 55 of the plate. Mounted on the bushing 50<1> and rotatable relative thereto is a pulley 47 driving the spool 13 by a belt 50, and driven by springs 48 connecting pins 46 mounted in the plate 49 to pins 44 on the periphery of a projection 52 of the pulley. The pulley 47 and the driving pulley are arranged so that the periphery of the hub 13 rotates faster than the linear speed of the film. In a recess in the plate 49 is a bell-crank lever, one arm having a pin 63 actuated by a slot 65 in the portion 52 of the pulley 47, and the other a pin 67 coacting in one position with the portion 37 of the trigger 33. When the film becomes attached to the spool 13 as described in Specification 365,304, the retardation of the pulley 47 relative to the plate 49 due to the sudden deceleration of the spool 13 causes movement of the slot 65 relative to the plate 49. The pin 63 causes the trip lever to rotate, and the pin 67 to strike the member 37 on the next time of passing. The movement of the member 37 is transmitted to the trigger 33, and the latch 27 is released to allow the guides 15, 17 to move and clear the take-up spool 13.

In a stable, some air is extracted and some recirculated by a fan unit loacted in a vent pipe in the roof of the stable. The fan unit comprises a fan 11 within a duct 28 and below a duct 8 which is located within the vent pipe (not shown). Part of the air withdrawn from the stable flows axially upwardly into the vent pipe and part is deflected by a baffle 24 to return radially into the room. In an alternative embodiment two fans are employed, one axial fan within the duct 8 and one centrifugal fan below the duct 8, which fans may be driven independently by thermostatically controlled motors. Air may be let into the room by means of up-turned inlet pipes (7, Fig. 1) or by means of an annular passage 33 around the duct 8. The rate of outflow of air is controlled by simultaneously operable dampers 13, which are lifted by the air flow to an extent which is controlled manually (Fig. 2) or by a thermostatically controlled servomotor 39. The rate of in-flow of air may be controlled by a slidable duct length 34 which protrudes beyond the inner end of the annular passage 33.
