Abstract: 696,881. Resilient mountings. M.B. MANUFACTURING CO., Inc. Feb. 20, 1948 [Feb. 21, 1947], No. 5144/48. Class 108 (iii). A suspension system for isolating a body against vibration with not more than two sets of coupled modes, comprises a number of vibration isolator units all having the same stiffness ratio, attached to and supporting the body at points in a plane parallel to two of the inertial axes of the suspended body, each point of attachment being determined by the formula in each of two orthogonal planes, s and d being the horizontal and vertical distances of the mounting unit axis from the c.g. (m), as shown in Fig. 11, r the radius of gyration of the body about an axis perpendicular to the plane in which s and d are measured, and Kv and Kh are the vertical and horizontal stiffnesses of the mounting. The respective curves B-H and B1-H7 (which are omitted in the upper half of the Figure for the purpose of clarity) relate to mountings having the same stiffness ratio Kv/Kh but different absolute stiffnesses, and are derived from the same equation, the left-hand side of which is multiplied by <12>#10 or a multiple thereof. The scale of the co-ordinates of the diagram is chosen so that r equals unity. The curves M represent ratios of maximum to minimum natural coupled frequencies and the curves N, ratios of minimum to translational frequency. The curves O represent the location of nodal points. In use, the outline of the body in a plane parallel with two principal axes X, Y (Fig. II), is superposed on Fig. IV with m coincident with the origin 3 and the axes X, Y parallel with the axes s/r, d/r. The points on the outline for positioning the respective mountings so that the ratio of maximum to minimum natural frequencies of the suspended body is a minimum, are indicated by the intersection of the body outline with the curves A-H and A<1>-H7. The intersection of the outline with the curves M, N, O indicate the respective frequency ratios and nodal points. Specifications 692,691 and 696,055 are referred to.

Filed: 1923-02-23
Abstract: 212,090. Watkins, A. A. Feb. 23, 1923. No Patent granted (Sealing fee not paid). Vibration-dampers.-In a vibration-damper for a vehicle spring, a central disc B is connected directly or through a lever arm to the vehicle chassis and one disc C of a pair of outer discs A, C, which are rendered relatively non-rotatable by a coupling H, is attached by toggles M, N to a lever arm L connected to the vehicle axle. Movement of the arm L about a central spindle F presses the discs together against the action of an adjustable spring K the range of action of which is limited by the abutment of the disc A against a collar G on the spindle F. Greater displacement of the arm L causes its end to engage one or other of two adjustable stops O, P when the outer discs A, C are moved relatively to the inner disc B. Wedges may be used instead of the toggles.

Title: Improvements in or relating to shoe-upper lacing machines
IPC: A43D11/08
Filed: 1919-03-05
Abstract: 144,360. British United Shoe Machinery Co., (United Shoe Machinery Corporation). March 5, 1919. Lacing.-The invention consists in a cord-tensioning device applicable to machines for lacing shoe uppers, such as that described in Specification 3396/08. The cord is tensioned at alternate reciprocations of the needle. The thread passes through guides 22 which are pressed inwards to tension the thread by a spring-pressed lever 20. The upper end of the lever is conical, and engages hollows 30, 28, alternately deep and shallow in a rotatable disk 26. As a needle 14 carried by a slide 16 reciprocates towards the lacing-mechanism at 2, 4, &c., the disk 26 is rotated a step at a time by a pawl 36. In this way as the lever 20 engages a deep depression in the disk 26 it tensions the cord and relieves tension at the shallow depressions. There is no tension during the forward stroke of the needle which carries the locking-cord through the loops held by the spindles, but the. tension will be effective during the return stroke which draws tho severed end of the cord from the loops and will remain applied during the forward strode which carries the severed end of the cord to a stationary cord gripper 6, and will again be relieved during the return stroke which presents the cord to be acted on by the looper spindles 2.

Title: Improvements in and relating to the production of sulphur
Inventor: FRANKLIN REGINALD GEORGE
IPC: C01B17/06
Filed: 1952-03-05
Abstract: Sulphur is produced continuously by passing a mixture of an alkaline earth metal sulphate, carbonaceous material, and silica or clay downwardly through an externally heated retort such that said mixture is heated to a temperature of 900-1400 DEG C. and passing the resulting gases, with or without prior separation of sulphur upwardly through a second externally heated retort down which pases a mixture of an alkaline earth metal sulphate and carbonaceous material, together if desired with silica or clay, which mixture is heated to a temperature of 500-1100 DEG C.  The solid residue leaving the second retort may be recycled to the second retort, if necessary after the addition of carbonaceous material. When the mixture fed to the second retort contains silica or clay, the solid residue leaving the retort may be used, if necessary after the addition of carbonaceous material, as the feed to the first retort.  The alkaline earth metal sulphate is preferably in the form of calcined gypsum or natural anhydrite. Carbonaceous materials specified are coal, coke, charcoal or bitumen.  In general the quantity of carbonaceous material employed is not more than that required to give 1 mole of carbon per mole of alkaline earth metal sulphate.  The quantity of silica and/or clay employed may be such as to give up to 2 moles of silica or of silica and alumina per mole of alkaline earth metal sulphate.  A reducing gas, for example hydrogen or carbon monoxide may partially replace the carbonaceous material.  In order to produce an intimate mixture of the components of the solid feed, the components may be ground, for example to less than 300m , and the mixture may be granulated or moulded with the aid of a bonding agent, for example water or an aqueous emulsion of bitumen.  Alternatively granules or moulded pieces containing alkaline earth metal sulphate and silica or clay may be mixed with carbonaceous material in particulate form. When the solid feed to the second retort consists essentially of an alkaline earth metal sulphate and carbonaceous material, the mixture may also be in the form of discrete pieces or granules of the two components. Specifications 694,035 and 719,235 are referred to.
