Title: Improvements in train wheel unit
IPC: B61F3/12
Filed: 1952-09-24
Abstract: 730,303. Underframing of railway vehicles. KREISSIG, E. F. Sept. 24, 1952 [April 8, 1952; July 7, 1952], No. 23997/52. Class 103 (6). A train wheel unit comprises a continuous resilient girder 2 to which axles 1 or half axles are rigidly secured so that the girder 2 may bend to the shape of a curve thereby causing the axles to radiate. A plurality of train units may be joined by couplings 3 which maintain the continuity of the girder 3. Wheels 7 may be rotatably mounted on axles 1 which are secured to the girder 2 either opposite each other, Fig. 3, or in staggered relationship, Fig. 4. Alternatively the wheels are secured to rotary axles arranged above or below the girder 2. Wagon boxes 4 are supported on the axles 1 by spring 5, Fig. 5. The cross-sections of the girder 2 at its ends may be varied to ensure an elastic curve which adjusts all axles with certainty radially or over-radially according to requirements. Alternatively the effect is obtained by providing a link 9 between the waggon box 4 and each end of the girder 2, thereby utilizing the centrifugal force of the wagon box 4 to control the radiating effect. In a modification, the single girder 2 is replaced in part by two parallel resilient girders 10 connected by a rigid transverse member 12 and resilient transverse members 11. Wheels 13 are mounted on axles secured to the girders 10 and the units are connected by central resilient longitudinal girders 2. In a further modification, rigid wagon boxes 14 are connected together by springs 16 rigidly secured to transverse girders 17 of the boxes 14 on which the axles 15 are mounted in an angularly rigid manner.

Abstract: 277,384. Meindersma, W. Sept. 13, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 14, 1927]. Paddle wheels; vibrating fins. - A feathering paddle vane or vibratory fin in which the blade axis describes a cone for each revolution of the driving shaft and the blade is feathered on that axis is supported by at least three places by the driving and controlling elements. A rope pulley 9, Fig. 1, mounted in a fixed ball bearing 6 is integral with a ring 5 which is gimbal jointed by diametrically-opposed pairs of pivots 4, 3 to a tumbler 2 forming the termination of the fin shaft 1.

Enamels.-The glasses and enamels described in the parent Specification are made more resistant to chemical action by increasing the silica content, the boric acid content being decreased at the same time in order to maintain the low fusing-point. The alkaline or alkaline earth oxides, selected in accordance with the typical molecular composition given in the parent Specification, are preferably replaced more or less by other oxides, such as those of zinc, magnesium, calcium, barium, or lithium, which reduce the coefficient of expansion. The resultant glasses and enamels have the following molecular composition:-PbO, 1; Zn O (or Al2 O3, Ca O, Mg O, BaO), 0.04 to 0.15; Si O2, 0.3 to 0.6; Li2 O (or aNa2O, K2O), 0.04 to 0.15; B2 O3, 0.23 to 0.35; colouring oxide 0 to 0.1. For making the enamel opaque, fluorides such as cryolite or calcium fluoride can be fused. with the material, or refractory oxides and salts of metals may be added during the powdering of the fused material.

Abstract: 1,149,792. Regeneration of filter medium. SWECO, Inc. 30 May, 1967 [2 June, 1966], No. 24632/66. Heading B1D. Spent filter medium (e.g. filter aid) whose average particle size has approximately a two fold difference from that of filtered material entrapped 'by the medium is recovered from the filtered material by slurrying in an inert liquid and subsequently passing the slurry over a vibratory screen having a mesh size such that the greater portion of the filter medium is retained on the screen while the liquid and undesirable fines pass therethrough. The slurry may first be pre-filtered through a filter having a mesh size sufficient to pass the filter medium and filtered material but retain relatively large particles of solid. The medium may be fibrous or particulate, e.g. diatomaceous earth, paper pulp, asbestos fibres, precipitated calcium carbonate. The average particle size of the medium may be about 40Á and about twice the size of the average particle size of the undesirable fines. The above method may be used for concentrating a slurry by filtering the slurry using a particulate filter medium, regenerating the filter medium as above using an amount of liquid to provide the desired concentration of final slurry of fines.

In an indicator device a member movable through a succession of settings carries a plurality of elements which co-operate with a group of transformers such that, upon a pulse being applied to the transformer primaries, a group of pulses characteristic of the position of the member appears at the secondaries. In the embodiment described a belt-type indicator comprises a character belt 2 driven by wheel 3. Seven transformers 8 having H-cores are placed along the belt, the positions of the poles being shown shaded. The belt carries a number of conductors (not shown) so placed that for each character appearing at the left-hand end of the indicator a certain combination of the transformer cores is bridged by the conductors. Thus, when the primaries are pulsed, a combination of pulses is obtained at the secondaries. This combination is compared in a register with a combination representing the desired position of the belt. If the combinations differ an electromagnet stepper motor is energized to drive wheel 3 until the belt is in the required position and therefore displaying the required character. The use of a parity check bit is mentioned.
