Title: Improvements in furnace construction
IPC: F27D1/04
Filed: 1935-02-25
Abstract: 432,526. Furnace roofs and walls. DETRICK CO., M. H., 140, South Dearborn Street, Chicago, U.S.A. Feb. 25, 1935, No. 6055. Convention date, Oct. 8, 1934. [Classes 51 (i) and 51 (ii)] A tile for use in the construction of furnace arches and walls, having a head portion formed to engage an anchoring member, has on at least one face, series of projections or ribs with intervening depressions or grooves, the ribs and grooves alternating both along the length of the face and transversely across it. As shown in the Figure the narrow faces of the tile have transverse ribs 27<a>, while the broad faces have two series of ribs 19<a>, 24<a> so arranged that the ribs of each series are aligned with the grooves of the other. The ribs 19<a> are bevelled at both ends and extend half the width of the tile, while the ribs 24<a> are bevelled at one end only, and to this extent are shorter than the ribs 19<a>. The remaining portion of the width of the face may be plane or may, as shown, have bevelled projections 21<a>, which, with the ribs 24<a> on an adjoining tile complete ribs equal in length to the ribs 19<a>. The opposite faces of the tile are complementary, i.e. a rib on one face corresponds in position with a groove on the opposite face. In building an arch a row of similarly oriented blocks is hung from overhead supports, and in the adjacent rows the blocks are reversed, so that owing to the unsymmetrical head the narrow faces break joint, and the ribs 19<a> of one row fit into the grooves 25<a> of the other. One broad face of each block may be plane, and in this case the blocks are arranged in rows with their plane faces in contact. In building a convex radial arch rows of blocks such as that shown in the Figure are alternated with wedge-shaped blocks of half the width which have plane parallel, and ribbed converging faces. The blocks may be formed by dry pressing.

Title: Improvements in or relating to fastenings for sliding doors on vehicles
IPC: B60J5/06
Filed: 1939-02-24
Abstract: 525,633. Vehicle door fastenings. OVERTON, W. Feb. 24, 1939, No. 6140. [Class 44] A vehicle door supported by carriages or runners moving along a track rail is held in the open or closed position by a yielding catch disposed in the track and co-operating with a part carried by the door. In Fig. 1 the door a is carried by brackets c with rollers running on a track rail b of channel section. Bifurcated members g secured in the track near the ends of the rail and adjustable by screw threaded stem and nuts j have balls l housed in the jaws and loaded by springs m. Pegs e, f carried by a bar d secured to the brackets c are respectively retained by the balls when the door reaches the closed or open position, the springs being strong enough to hold the door against release by accelerations of the vehicle, but yielding under manual pressure applied to the door. Alternative forms of yielding catch may be used. In one, the balls are replaced by plungers. A pair of suitably shaped spring-loaded pivoted jaws between which the peg is received, a single pivoted jaw with cranked and tapered end adapted to engage over and resiliently retain the peg, and a bowed spring or spring-loaded cam extending into the path of one of the rollers which is resiliently held thereby are mentioned. Specification 483,682 is referred to.

Title: Improvements in guards for presses
IPC: F16P3/06
Filed: 1924-03-11
Abstract: 234,217. Hassall, J. March 11, 1924. Guards; guards, controlling.-In cam-operated guards for power presses, the return movement of the guard is timed to start before the press ram reaches its lowest position, and the guard is carried at an adjustable distance from the face of the machine. The shield j, j<2> of adjustable depth and provided with a spring buffer j<1>, is guided by rollers or slippers running on a rail or rails k and is operated by a link n, adjustable arm m, m<1>, pinion p, rack q, and face cam a, the arm m, m<1> being axially adjustable on the pinion shaft o and the guide-rail supports s being telescopic. As the return of the guard is effected at the " dead-centre " period of the ram, the work may be fully uncovered before any substantial part of the upstroke of the press has occurred, without necessitating an abruptlycontoured cam. In a modification, a drum cam actuates a swinging lever directly linked to the guard or provided with a toothed quadrant to engage the pinion p.

IPC: H01J19/28
Filed: 1953-03-06
Abstract: 730,821. Thermionic-cathode tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 8, 1954 [March 6, 1953], No. 6218/53. Class 39 (1). [Also in Group XXII] A tubular electrode such as an anode is built up of a number of sections such as that shown in Fig. 10, each consisting of a partially tubular portion la, 1b, having fins 2 extending from each edge, and a web portion 3 extending from the tubular portion; the sections are assembled by attaching the fins to one another so as to complete a tubular anode, as in Fig. 1. A section is made by first stamping the shape out of metal sheet, Fig. 3 (not shown), folding symmetrically in two and turning out the fins, and then pressing to the final shape of Fig. 10 in a tool. The ends of the tubular portion may be belled outwardly, as at 21. The ends of the web portion are stepped, as at 17a, to seat mica insulators which support and locate other electrodes. Lugs 17 formed on the webs pass through slots in the micas, and are bent over to clamp them in position. Fig. 11 shows the construction adapted to a double diode, the webs 3 of the upper section being staggered with respect to the webs 3 of the lower section.
Patent GB-164443-A (GB)
Title: Improvements in or relating to time-controlled indicating or recording mechanism
IPC: G07C3/06
Filed: 1920-03-01
Abstract: 164,443. Ganter, H. E. March 1, 1920. Roller and sheet re cording - mechanism. In an indicating and recording device in which a clock train drives a record member such as a paper band, the escapement is driven by a separate clock train, each of the clock trains being positively and separated driven, but both are interconnected, as by worm gearing, so that the drive of the record member is regulated by the escapement-controlled train. The speed of delivery or rotation of the record member is determined by the position of the change-speed members. Instead of using separate driving. springs, the separate ends of a single spring may be used for this purpose, or weight-driven clock trains may be employed. The invention is particularly applicable for use in connection with electric current consumption meters in which a band of paper is moved under a. pen at a rate determined by a clock, with which the driving- mechanism for the band of paper is inter-related. In the arrangement shown in Figs. 1, 3, and 6, a paper strip 23 mounted on the shafts of end rollers 17, 19 is moved past a pointer 24, movable on a shaft 15, by a spring-drum 29, the clock work escapement being driven through a separate train from a spring barrel 32. These spring barrels are mounted between side plates 30, 31, and are enclosed in a flexible cover member 49 marked to indicate the position of the train members. The escapement train drives indicating- pointers 33, 34 movable over a dial 35. The spring barrel 29 drives the paper roller 20 through the train of wheels, of which the wheel 66 on the shaft 68 gears with a wheel 67 on the barrel shaft. Included in the train of gearing is a ratchet-wheel 69, whereby the paper train may be held stationary when the change-speed members, shown in Fig. 6, are out of gear. This gearing comprises movable pinions 88, 89, 90 slidable on a squared shaft 86, and a loosely-mounted pinion 91. The pinions are movable by a hand-lever 101 into gear with pinions on a shaft 81, which is geared to the intermediate paper strip roller 22 on the shaft 16. The shaft 86 carries a worm wheel 96 with which engages a worm pinion 97 on a shaft 98 geared to the spindle 60 of the escapement-controlled train. By this arrangement, the rotation of the paper roller 22 is under the control of the escapement device. The change-speed lever 101 operates a fork 103 embracing the shaft 86, and is pivotally connected by a set-screw 104 to a bracket member 105. It has side springs 106 which tend to maintain the lever parts in operative alignment, a spring-pressed plunger engaging in notches in the bracket member to hold the control lever in the adjusted position. Specification 4135/87 [Class 97, Philosophical instruments] , is referred to.

Title: Improvements in the production of fine fuel dust
IPC: F23K1/00
Filed: 1927-03-07
Abstract: 267,154. I. G. Farbenindustrie Akt.- Ges. March 8, 1926, [Convention datel. Void [Published under Sect. 91 of the Acts]. Fuel. - To produce a fine fuel dust which passes through a sieve of 10,000 meshes per sq. cm., brown coal (lignite) or peat, after any necessary removal by washing of heavy mineral constituents, is ground in the wet state e.g. between rough metal sheets or in an edge-runner mill, together with a colloid or colloid-forming substance. The resulting paste is dried and again ground, preferably in a disintegrator mill. " Cellular pitch," a product resulting from the evaporation of sulphite cellulose liquor, or naphthol pitch, may be employed as colloids, or caustic alkalis, ammonia or ammonium carbonate, which form colloids with humus substances in the lignite, are suitable agents with wetting media such as saponines and organic sulphonic acids. In an example 1 part by weight of a 50 per cent solution of cellular pitch is added to 10 parts of lignite containing about 50 per cent of water and the mixture is vigorously ground until a thick paste is formed and a test portion when stirred into water yields a stable suspension of lignite particles of the order of 0.01-0.001 mm. The paste is dried and ground in a disintegrator mill. As an alternative all the paste may be converted into a thin suspension from which mineral particles separate out and the fuel obtained by filtration or precipitation as by electro-phoresis. Reference has been directed by the Comptroller to Specification 2513/88.

Abstract: 1,113,489. Semi-conductor devices. SIEMENS A.G. 10 Feb., 1967 [11 Feb., 1966], No. 6452/67. Heading H1K. Two non-contiguous closely adjacent regions 2a/2b and 2c of a semi-conductor surface are covered with doping and/or electrode-forming material 2, 4 by a process involving covering at least the first region 2a/2b with the material 2, covering the material 2 on the region 2a/2b with an etch-resistant layer 3 which leaves the second region 2c free, etching the region 2c, and then depositing the material 4 on to the region 2c. The etch-resistant layer 3 is then removed. In the embodiment shown the material 2 is deposited over the entire surface. The etchresistant layer 3 may be of a photo-varnish or of silicon dioxide, and during the etching process to remove the material 2 from the circular region 2c the layer 3 is slightly undercut, as shown. Deposition of the material 4 is then performed by vapour deposition or by a beam of material, such as by cathode sputtering or with an ion beam. The shade effect of the undercut thus separates material 4 from material 2. The etching of the region 2c may be continued so as to form a trough in the semi-conductor surface in which the doping or electrode material 4 is deposited. Additional masking, e.g. of etchresistant material, may be applied after removal of the excess material 2 to protect other parts of the surface against being covered by the material 4. The second region 2c may, in this case, be defined partly by the first etchresistant layer 3 and partly by the additional mask. The invention may be applied to transistors of planar or mesa form.

Title: Improvements in spring devices incorporating multi-closed cell deformable spring masses
IPC: H01R12/51
Filed: 1964-02-17
Abstract: 1,032,679. Elastomeric springs. R. L. OLSON. Feb. 17, 1964, No. 6521/64. Heading F2S. A spring device comprises a relatively rigid support member 413 having at least one recess, e.g. concentric grooves 424, and a multi-closed cell, bulk compressible, resiliently deformable spring mass 420, e.g. of an elastomeric material, in the recess. The spring mass 420 includes a body which completely fills the recess and a portion projecting outwardly therefrom for engagement with a second member 419. The mass is so shaped that resistance to compression movement is of a desirable initial softness but then increases at a rapid spring rate which can be plotted as an asymptotic curve. When the projecting portion is completely received within the recess no material of the mass 420 is pinched between the second member and the rigid support member 413. The elastomeric springs 420 may be secured in the grooves during their formation as by curing in situ by vulcanization, baking, catalytic curing or cooling in the case of polyurethanes. Small bubbles 420A are provided near the exposed surface of the springs 420 and large bubbles 420B in the interior. The exposed surface of the springs may be smoothly curved (Fig. 4, not shown). Hexagonal cross-sectioned springs may be housed in grooves formed in a thick plate (Fig. 3, not shown). In a further embodiment (Fig. 7, not shown) a stack of spring units 913 are guided on a mandrel 964, closed air spaces 918, 982 being formed between the springs 920 and between the springs and the mandrel, respectively. The device may be in the form of a bumper (Fig. 9, not shown), in which a plate 1019 is attached to the spring 1020 and which is guided in a member 1089. The plate 1019 is provided with a protective cover such as the bonded on rubber bumper layer 1018A. The spring 1020 is housed in a recess in a casing 1013, the base of the recess being formed by a screwed in member such that the initial compression of the spring and its exposed shape may be altered. The sides of the plate 1019 are bent upwardly so that the outer ends co-operate with casing 1013 to form a stop. The spring 1020 is of circular cross-section. A longitudinally extending rubber spring (Fig. 11, not shown) is partly confined within a thin metal member, the axially extending edges of the metal member being bent over a part of the upper surface of the spring. The bubble-like cells may be at different pressures and some may contain a highly viscous material or liquid such that the spring may also act as a shock-absorber. The cells have volumes equivalent to the volume of spheres having diameters between 0À001 and 0À03 inch.
