Title: Improvements in or relating to the lubrication of spindles for spinning or twisting machinery
IPC: D01H7/20
Filed: 1923-08-08
Abstract: 206,117. Compagnie d'Applications MÚcaniques. Oct. 30, 1922, [Convention date] . Ball or roller bearings; spring supports.-In a spinning-machine spindle provided with a dismountable ball-bearing 5 at its mid-length and a spring-mounted step-bearing 9, the parts are so arranged that the movement of the shaft 1 due to the insertion of empty yarn-holders causes the lubricating-oil to rise and lubricate the ball-bearing 5. The inner ring 4 of the bearing is secured to the shaft 1, and the outer ring 6 is mounted in a socket 7 screwed on to the spindle-holder 8. The step-bearing 9 is provided with two apertures 12, a shoulder 13, grooves 15 for the return of the oil, and an annular space 16 for collecting the returning oil. The oil normally reaches to the lower part of the bearing portion 10, but on in. serting an empty yarn-holder and compressing the spring 11 the oil is impelled towards the top. The downward motion of the spindle is limited by the engagement of the shoulders 13, 14, Fig. 2, and the oil is forced up between the shaft 1 and step-bearing tube and thence projected on to the balls 5. As the spring 11 extends, the oil returns through the annular orifice 16 and the grooves 15. In a modification, a metallic washer a, Fig. 3, is secured to the step-bearing tube b so as to divide the apertures c into two parts, the upper part d being very small. An elastic washer e is pressed against the washer a by the spring f. When an empty yarn-holder is placed on the spindle, the spring f is compressed and the oil is driven through the apertures c between the tube b and shaft i to lubricate the balls. The oil returns through grooves along the outer surface of the tube b and through the orifices d to the oil supply.

Filed: 1950-08-15
Abstract: 703,164. Tyre removers. RANDALL, N. G., and DAVIDSON, D. H. M. Nov. 8, 1951 [Aug. 15, 1950], No. 20283/50. Class 144(1) In a tyre removing machine a wheel 11 is supported in a horizontal plane against downward thrust on support means 3, and a mobile means 20 is moved over the wheel to allow readily detachable connection to be made between the support means 3 and a lifting mechanism 55, 56 carried by the mobile means 20, a plurality of tyre engaging abutment members 40 being carried by the mobile means 20 so that when the wheel and its support is raised by the mechanism 55, 56, the tyre is stopped by the members 40 and the wheel is lifted out from the tyre. As shown a support pillar 3 is screw-threaded at its lower end to receive a wheel support member 6, 9 which may be vertically adjusted thereon. The free end of pillar 3 has a circumferential groove 4 to receive a C-washer 57 coupling the pillar 3 with a bottom plate 56 of the lifting mechanism. The mobile means 20 is in the form of a trolley comprising three castored legs 24 removably depending from the outer ends of three arms 21 radiating from fixed support plates 50, 51. The arms 21 are interspaced by five radial arms 22 and each of the arms 21, 22 slidably supports depending bracket 36 to which is pivoted a lever arm 38 carrying a tyre abutment blade 40. Each lever 38 is spring-loaded to urge the blade 40 normally towards the centre, and the pivot 39 of the lever 38 is positioned so that upward pressure on the blade 40 tends to assist this action. This ensures that the upturned toes of the blades 40 will engage under the wheel rim as the wheel is withdrawn from the tyre during the operation of the machine. To hold the levers 38 and blades 40 in their normal radially outer position against pressure on the blades 40 a releasable eccentric 44 is provided on each bracket 36. The lifting mechanism comprises upper and lower plates 55, 56 interconnected by four rods 54 which are slidable in guide apertures in the fixed support plates 50, 51. The upper plate 55 rests on the piston of a jack 53 supported on plate 50 and a hand-operated lever 61 is provided for lowering the mechanism 55, 56 for effecting connection with the wheel support 3.. In a modified arrangement, the brackets 36 are interconnected by linkages so that radial adjustment thereof along the arms 21, 22 may be effected simultaneously and uniformly by a single handoperated lever.

Patent GB-1276891-A (GB)
Title: Mutator
IPC: H03H11/12
Filed: 1969-05-27
Abstract: 1276891 Impedance converters PURDUE RESEARCH FOUNDATION 27 May 1969 [27 May 1968] 20452/69 Heading H3U [Also in Division G4] A desired non-linear element of a certain kind is realized by means of a two-port network (called a "mutator") which transforms the characteristics of a known non-linear element of a different kind. When the element of one kind is connected across one port of the network the characteristics of the element of different kind are available at the other port, and vice versa. The synthesis is illustrated diagramatically in Figs. 5, 6, 7, where the I-V characteristic of an actual non-linear resistor is transformed by the network LR1 into the #-I characteristics of a virtual non-linear inductor. The same LR network may be used to transform the characteristics of an actual non-linear inductor into those of a desired non-linear resistor (Figs. 8, 9, 10, not shown). In practice, there are three types of such networks, viz L-R, C-R and L-C mutators, and Fig. 1A shows the characteristics and schematic realizations of the L-R type. Figs. 1B, 1C (not shown) similarly illustrate realizations of the other two types. The L-R mutator may be realized in two basic ways designated 1 and 2 and defined by the transformations shown. Both basic networks may be realized in more than one way. In the schematic networks shown, controlled sources are designated by diamonds, an arrow being used to distinguish a controlled current source and Œ signs a voltage soutce. It will be seen in all cases that the current and voltage sources are controlled by the time derivative or time integral of the non- linear element connected across one of the ports. The Specification gives an example of a suitable voltage-controlled current source (Fig. 4, not shown), and such a source is used in the network of Fig. 2 which is a practical elaboration of realization 4 of an L-R mutator of the first kind. The Specification also gives a practical circuit for a C-R mutator. The networks are used to simulate elements having non-linear characteristics not normally available, and may be used in analogue circuits of the type in which a computer selects a set of non-linear elements to satisfy a specified set of network functions.

Title: Improvements in methods of producing and reproducing illustrative drawings or plans
IPC: G09F19/10
Filed: 1933-07-20
Abstract: 421,347. Diagrams; pictures. HISCOCKS, C. W., 27, Chancery Lane, London. July 20, 1933, No. 20503. [Classes 11 and 146 (ii)] In a method of producing illustrations of an article or design, so as to show several complementary phases of the article, &c. step by step from the outside to the interior, views showing the several phases are produced on a single sheet of material in association with registration markings, whereby the sheet may be folded into a paginal unit to bring the different phases into exact register and into proper relation with each other, as in the actual article. Drawings of the different phases are made and shaded by wash methods, and are then photographed, and half-tone or multicolour blocks are produced, from which the illustrations are printed on a single sheet. Alternatively, the illustrations may be produced directly from the photographic plates or films. In the case of a sheet showing five phases of an article, the fifth phase 1 is formed in the centre of one side of the sheet, and the others 2, 3, 4, 5, are formed on the reverse side, so that, when the sheet is folded into pages along registration markings, which may be printed on in the form of notches or slits, the pages can be lifted up one by one to show the successive phases. The pages may be out to the outlines of particular phases. In a translucent unit, suitable for advertising purposes, the different phases 12, 13, Fig. 4, are printed, preferably in colours, on one side of the sheet, and, after folding, the edges of the pages are secured together by adhesive, so that different phases of a design are revealed by reflected and by transmitted light. Diffusion sheets 14, which may be coloured, may be interposed between the various phases.
