Title: Improvements in centrifugal fluid fans
IPC: F04D29/58
Filed: 1957-11-04
Abstract: 827,566. Centrifugal fans. FULLER CO. Nov. 4, 1957 [Dec. 3, 1956], No. 34338/57. Class 110(1). A centrifugal fan impeller has axially-extending blades, and a channelway extending along the back of each blade, each blade forming the front wall of its channelway, the front and back walls converging outwardly, and each channelway has an inlet near the impeller hub and an outlet near its radially outer edge. Radially extending blades 17 are attached to a hub 3 and a back plate 20 which is of spider form as shown, the plate 20 comprising a single sheet or separate members welded together. A secondary blade 22 is attached to the forward face of each blade 17 and also to the back plate 20 and to an individual wall 25, and extends outwardly towards the preceding blade 17. Bearing 7 and driving motor 12 are protected from the hot gas handled by the fan by a radiation shield 35. The space between the shield 35 and the fan casing wall 6 is enclosed by a hood 33 which extends to a point beyond the bearing 7. In operation, the fan draws in hot gas at 14 and discharges it at 16, and at the same time air is drawn in through ports 27 in the back plate 20 and passes through the channels between the blades 17 and 22 to cool the fan shaft, hub and blades. Most of this air enters through a hole 36 in the shield 35, and passes over and cools the bearing 7 and shield 35, but some enters through a hole 38 in the base and helps to reduce the transmission of heat to the motor 12 and bearing 7 through the base. Air may, however, be discharged through the hole 38. Flow of air is assisted by an impeller 29, which is larger in diameter than the hole 36 to prevent radiation of heat through the hole 36. A ring 28 secured to the back plate 20 has a close clearance with a surrounding hole in the wall 6, to prevent leakage of air or gas through the hole. By adjusting the position of the impeller 29 on the shaft, the size of the annular air-flow space between the impeller and the ring 28 can be varied, thereby varying the flow of cooling air. The blades 17 may curve forwardly or rearwardly at their tips. Dispersed liquids may be introduced into the air stream, to provide evaporative cooling. In a modification, the impeller 29 and hood 33 are omitted, and the radiation shield is located close to the fan casing wall and has a central hole with a small clearance from the ring 28. In addition to the flow of cooling air into the fan through the ring 28, air flows through the aforementioned clearance and the space between the radiation shield and the fan casing wall to form a barrier against heat transmission.

Title: Shock-absorbing pivot bearing
IPC: G12B3/04
Filed: 1957-11-04
Abstract: 880,905. Bearings. SEITZ & CO. Nov. 4, 1957 [Nov. 5, 1956], No. 34352/57. Class 12 (1). A shock-absorbing bearing comprises a spring- pressed bearing element 5 located in a bore 3 of a body member 1 and adapted to receive a shaft pivot 7, a screwed plug 11, having a cylindrical extension 12, also being located in the member 1 so that it can be set in a position in which it holds the bearing element 5 immobile against the conical face 2 in the end of the bore 3. The bearing element 5 is held coaxial with respect to the bearing body 1 by means of a member 9 located in the bore 3. After the bearing element 5 has been clamped in its immobile position, the correct clearance with respect to the shaft pivot 7 is set by rotation of the body 1 which is screwed in a housing 15. The bearing element 5 is then unclamped by unscrewing the plug 11. The internal rim 1a may be formed by a pierced element of synthetic corundum or metallic setting carrying a pierced jewel. In a modification, a pierced bearing element 5a, Fig. 3, is provided, and in a further modification, the bearing comprises a pierced jewel 5b and a cap jewel 5c set in the bottom of a sliding member 9a.

Title: Article handling apparatus
IPC: B65G47/54
Filed: 1961-09-26
Abstract: 958,145. Endless conveyers; roller conveyers; stacking. FMC CORPORATION. Sept. 26, 1961 [Dec.22, 1960], No. 34384/61. Headings B8A and B8C. Articles transferred from a conveyer 13 to a conveyer A may be orientated through 90 degrees by the action of rollers 56. Some articles may not be orientated thereby enabling articles delivered by the conveyer A to be stacked in groups, the articles of each group being disposed at right angles to the articles of adjacent groups. The conveyer 13 feeds cartons to an endless conveyer 23, the belts of which are downwardly swung about an axis 17 to deposit each carton on a plurality of pairs of rollers 55, 56. The latter are freely rotatable on respective shafts 54 mounted between a fixed frame member 48 and a vertically movable frame member 51. The latter may be raised by the action of a solenoid 63 (Fig. 4) thus lifting the rollers 56 out of engagement with a driving belt 71 and into engagement with a brake segment 61. The rollers 55 are continuously driven by belts 71. If the carton is to be orientated, the rollers 55 are lifted into braking position when the carton is delivered by the conveyer 23. It is then turned (as shown in dot-dash line 6) by the action of the rotating rollers 55 and the braked rollers 56. Switches S, S1, S2, S3 (see also Fig. 5), control the sequence of operations. When a carton engages switch S, contacts 81 open to de-energize a relay R, thereby closing contacts 86. The latter complete a circuit to the solenoid 63 which lifts rollers 56 into braking position, via contacts 109 closed by a contactor block 108 carried by an endless chain 106. Switch S also causes a coil 33 to be energized so as to remove a latch 31 from engagement with a lever 18c which controls the swinging of the conveyor 23 about the axis 17. A solenoid 27 which normally holds the conveyer 23 in its upwardly swung position is de-energized by the relay R. When the carton reaches a position in which it bridges switches S1 and S2, and thus momentarily maintains them open simultaneously, the solenoid 62 is de-energized to remove the braking and restore the drive on the rollers 56. When the switch S1 is disengaged relay R is re-energized through holding contact 84a. Closing of contact S3 operates a pawl 102 to drive the chain 106 one step. When the latter reaches a position in which no contactor block 108 is present to close the contacts 109, the rollers 56 will not be braked during the passage of the carton and so the latter will not be orientated. Thus three successive. cartons are orientated and are followed by three success sive cartons which are not orientated and so on.

Abstract: 1,082,271. Photographic colloid transfer processes. AGFA A. G. Aug. 24, 1964 [Aug. 24, 1963], No.34575/64. Heading G2C. In a process for the imagewise transfer of parts of a supported non-light sensitive transfer layer to the unexposed areas of a negative silver halide emulsion which is in contact with the transfer layer, wherein by treatment with a developer containing a silver halide solvent the unexposed silver halide of the photo-sensitive layer is dissolved by complex salt formation and reduced by development nuclei present between the silver halide and transfer layers, thus altering the adhesion between the emulsion and transfer layers, and the two layers are separated so that the portions of the transfer layer corresponding to the non-exposed areas of the silverhalide emulsion layer adhere to the latter and are torn out, and the portions of the transfer layer corresponding to the exposed areas of the silver halide emulsion remain adhering to the support of the transfer layer; the binder of the transfer layer consists of polymers which swell in water and/or alcohols and do not form silver salts, optionally admixed with other polymers e.g. containing carboxyl groups. Wax matrices and screen printing forms may be prepared by pressing the relief layer which remains behind on the transfer material is pressed on to a tissue paper or fine mesh fabric so that after separation of the two materials the relief layer is separated from its foundation and transferred on to the paper or fabric. The specified binders for the transfer layer are polyvinyl pyrrolidones, polyvinyl alcohols, polyvinyl acetates, copolymers of vinyl pyrrolidone and vinyl acetate, polyurethanes, polysaccharides (e.g. guar, dextrine tregacanth), polysaccharide derivatives (e.g. cellulose ether or starch ether), and proteins (e.g. gelatine or casein). The transfer layer may also comprise salts, non-swellable fillers and/or dyes and may comprise several layers; the dye in the remaining areas of the transfer layer after the transfer step may be used as a printing master by subliming the dye on to a receiving sheet.

Title: Improvements in or relating to television transmission or the transmission of images
IPC: H04N5/238
Filed: 1936-12-16
Abstract: 487,240. Television transmitters. RADIOAKT.-GES. D. S. LOEWE. Dec. 16, 1936, No. 34577. Convention date, Dec. 16, 1935. [Class 40 (iii)] Light from the subject 5 is so automatically attenuated that the range of fluctuation of the mean light intensity is reduced electro-optically. A Kerr cell, crystal or similar light valve 11 is in the path of the light and is controlled by - currents from a photo-electric cell 9 on which the subject is projected simultaneously with the projection on the transmitting cell 1. Alternatively, a controlling current, dependent on the intensity of the image, is obtained from the amplifier 4 by a circuit of the kind used for volume control in wireless, Fig. 2 (not shown). The controlling current is also used to shift the mean value of the signalling currents prior to, or simultaneously with, the modulation of a carrier. When using storing-electrode transmitting tubes, the controlling current also so regulates the scanning light or electrons that photo-electric charges are always compensated or removed. The apparatus may be used in conjunction with that described in Specification 486,896. Specification 404,020 also is referred to.

Filed: 1963-09-03
Abstract: 1,022,391. Bearings. N. V. PHILIPS GLOEILAMPENFABRIEKEN. Sept. 3, 1963 [Sept. 6, 1962], No. 34792/63. Heading F2A. A bearing assembly comprises a shaft arranged within a block formed with a cylindrical bore forming two relatively rotatable bearing members having co-operating cylindrical surfaces, wherein the cylindrical surface of one of the bearing members has a smooth portion and is formed with at least one helical groove on each end of the smooth portion of the surface such that, when one of the bearing members is assembled with the other to form an assembly and lubricant is supplied to the assembly during relative rotation of the two bearing members, each helical groove urges lubricant in the direction of the smooth portion, and wherein the grooves are constructed so that the urging effect of one is greater than the urging effect of the other, means being provided so that the excess lubricant which flows to the groove with the smaller urging effect is returned to the groove with the greater urging effect. The urging effect of the grooves may be controlled by making them of different pitch, width, depth or length. The returning means may comprise a duct or a porous member. The grooves may be on the shaft or bearing block. The lubricant may be grease, oil, graphite or water.
Patent GB-743519-A (GB)
Title: Improvements in or relating to travelling wave oscillator tubes
IPC: H01J25/46
Filed: 1953-12-14
Abstract: 743,519. Travelling wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 14, 1953 [Dec. 13, 1952; Dec. 20, 1952], No. 34810/53. Class 39 (1). [Also in Group XL (b)] In a backward wave oscillator a mechanicallymovable member is provided adjacent the delay line so that the phase velocity and consequently, since the delay line is dispersive, the frequency can be varied. The dispersion characteristics of the line are such that the electronic tuning band is narrow in comparison with the mechanical tuning band. The tube may or may not operate with crossed electric and magnetic fields. The beam may be initially focused by a suitable gun design. In one form, Fig. 9, which does not have crossed fields, the delay line comprises fingers 104 supported by block 106 and mechanical tuning means comprising bar 120 movable by rods 121 towards or away from the ends of the fingers. 11 is a coaxial output terminal and the other end of the line has an energy-absorbing layer to absorb any forwardly travelling energy. Alternatively, the bar 120 may be moved parallel to the fingers. The system may be circularly curved, the line being an incomplete circle and the tuning bar an incomplete annulus. The frequency variation is stated to be 10- 20 per cent of the central frequency. In another embodiment, Fig. 11, which uses crossed fields, tuning vanes 145 project into the spaces between delay line vanes 44 and their axial depth of penetration is varied by mounting them on a circular ring attached to a flexible diaphragm forming part of the tube wall and movable by externally actuated rods, Fig. 12 (not shown). The cathode may be artificially cooled. A crossed field tube with a multivane delay line, using tuning means similar to that of Fig. 9, is described with reference to Figs. 7, 8 (not shown). Comb-type delay lines similar to that of Fig. 9, but with an additional baseplate are described with reference to Figs. 5, 6 (not shown). Such lines are normally non- propagating since the magnetic and electric coupling between adjacent fingers neutralize one another. This is overcome by arranging a metal strip in the region of maximum magnetic or electric field to increase the magnetic or electric coupling. The tubes may be used in centimetre wave links or as detecting devices. Specification 699,893 is referred to.
