Abstract: 293,085. Crockett, R. A. March 25, 1927. Axle .structures.-In a wheel hub arrangement for motor or like vehicles, a boss on the axle casing or stub axle has flats engaging corresponding flats on a hub shell or brake disc to withstand braking torque and cylindrical parts between the flats to ensure concentricity of the parts. Coacting flats 3, 4 are formed between the axle casing 1 and a hub shell 5 and between the hub shell 5 and a brake disc 11, the whole being secured by tapered bolts 16 passing through the parts, parallel to the diameter. A modified form shows a brake disc having flats bearing on flats on the axle casing, the parts being connected by bolts parallel to the wheel axis. In a further modification the invention is shown applied to a front wheel stub axle. The hub shell 5 carries a, ball bearing 6 carrying the wheel 7 which is bolted to a flange 9 having a splined connection 10 with the end of the axle 2.

Title: Improvements in or relating to tools adapted for use in blind riveting
IPC: B21J15/04
Filed: 1955-03-22
Abstract: 800,427. Blind riveting. TUCKER EYELET CO., Ltd., G., and NEWSTEAD, C. March 21, 1956 [March 22, 1955], No. 8226/55. Class 83 (4). A tool for use in blind riveting comprises a body portion containing means arranged to provide a rivet setting force, means mounted on the body portion for determining the orientation of the mandrel of a blind riveting assembly with respect to said body portion and mechanism whereby the angular relationship between said body portion and said determining means can be adjusted and locked in position. The tool has a nose piece 38 one end of which constitutes an abutment 40. A mandrel engaging unit 46 movable in the nosepiece provides the setting force as disclosed in Specification 793,365. The mechanism for adjusting the angular relationship between the nosepiece and the body portion 2 comprises a stationary housing 8 and a rotatable housing 16 mounted thereon the nosepiece being carried by the rotatable housing 16. A rack member 6 projects from the body portion and engages a gear 26 (Fig. 2) mounted within the housings 8 and 16. A second rack member 32 attached to the mandrel-engaging unit 46 also engages the gear at a diametrically opposite but transversely offset position. An indexing and locking pin 36 engages holes 34 in the housing 8 and prevents relative movement of the housings. On loosening the nut 20 and withdrawing the housing 16 until the rack member 32 is disengaged from the gear 26 the housing and nose piece can be orientated as desired and relocked in the adjusted position. Other features of the tool and its operation are described in the abridgment of Specification 793,365. Specification 558,156, [Group VII], also is referred to.

Abstract: 952,163. Brackets. CABLE SUPPORTS Ltd. Feb. 26, 1960 [March 10, 1959], No. 8285/59. Heading A4B. [Also in Divisions E2, F2 and H2] A hanger 11 for use with a C-shaped channel 26 has a head 17 and also has formed on one side thereof a hook 18 and on the other side thereof a pair of abutment parts 42 for bearing against the abutment surfaces 20 of the C- shaped channel and projecting means 32 between the abutment parts, the width of the projecting means being slightly narrower than the width of the elongated gap in the C-shaped channel and the maximum dimension of the projecting means being greater than the width of the elongated gap, so that when the abutment parts bear against the abutment surfaces the projecting means enters the elongated gap to prevent the hanger rotating relative to the channel, the hook of the cable hanger being so located that when the abutment parts bear against the abutment surfaces of the C-shaped channel when vertical, the hook will retain an elongated member such as a cable or pipe placed in it. A closure element 12 for closing the mouth of the hook can also be provided. The hanger is provided with two rectangular sockets 23 which receive two dowels 24 on the closure element 12 to prevent relative rotation. The hanger is attached to the channel by means of a nut unit 34 and a threaded rod 33. The nut unit is positioned in the channel and the rod 33 is threaded into the nut until its tip engages the base of the channel when continued rotation forces the nut against the underside of the flanges 29 of the channel. The hanger and closure element are then positioned on the rod and a nut 30 clamps them together. A plurality of hangers and closure elements can be supported from a single rod and to secure the projecting means of an adjacent hanger the closure element has a groove 35. A spacing washer can be positioned between the hanger and the closure element when it is not desired that the closure element and hanger should clamp the elongated member between them but only loosely support it. Both the hanger and the closure element are formed with edge grooves 31 which can engage the channel when it is horizontal as described in Specification 952,164.

Title: Improvements in the construction of structural members such as roofs and floors
IPC: E04B5/43
Filed: 1945-04-04
Abstract: 595,156. Floors, walls, &c. GREEN, D. H. April 4, 1945, No. 8348. [Class 20(iv)] A structural frame member for floors &c. of buildings, comprises a series of loadcarrying torsion units in the form of closed geometrical figures, disposed concentrically in relation to one another, each unit being individually formed and having a section such that the required torsional rigidity is imparted to it, and linkage members, which hold the adjacent units in spaced relation, and are constructed to operate in tension and without any substantial beam action. In constructing a floor as shown, a series of rings 1, 1<1> &c. are arranged within the floor area with the outer ring 1 secured by the brackets 3 to the supporting columns 2 or directly to the walls. The second ring 1<1> is next secured in place by the linkage member 4, formed as an inclined strap with bent ends which are bolted or otherwise secured to the rings 1 and 1<1>, the members 4 extending radially and in alignment with the suspension or attachment points of the structure to the columns or walls. This process is repeated until the smallest ring 1<8> is in place. The structure is now encased in concrete 16. Alternatively, upper and lower metallic skins may be secured to the horizontal edges of the rings to form a floor or panel. The linkage member may be formed as one continuous strip. The torsion elements 1, 1<1> &c. may be formed from flat metal strips bent to circular, triangular, square, &c. shape, or of straight strips joined at the corners, or they may comprise fabricated elements such as the lattice beams described in Specifications 565,797, [Group XXII], and 604,737. The horizontal edges of the elements may be arranged other than in a common plane so as to form a domed or pyramidal structure. The torsion elements' may be of different geometrical forms, frames comrising alternating square and circular element being illustrated. A number of the frames may be juxtaposed to cover a desired area.

Title: Improvements in or relating to two-stage carbon dioxide removal process
IPC: C01B3/52
Filed: 1955-03-23
Abstract: Carbon dioxide is removed from hydrogen-containing gas obtained by interacting steam and methane, or from ammonia synthesis gas, by a two-stage absorption-desorption process, a major proportion of the carbon dioxide being removed in the first stage by scrubbing with a relatively large volume of an aqueous solution of potasium carbonate, preferably containing 30-40 per cent K2CO3 at a pressure of at least 90 p.s.i.g. and at a temperature of 240-270 DEG F. and regenerating the solution at a temperature within 50 DEG F. of the temperature during absorption and at a decreased pressure of not less than 10 p.s.i.g., the remaining portion of the carbon dioxide being substantially removed in the second stage by scrubbing with a relatively small volume of an aqueous solution of an alkanolamine, e.g. containing 40-60 per cent alkanolamine, at a temperature of e.g. 86-140 DEG F. and regenerating the solution by heating to e.g. 240-257 DEG F.  The alkanolamine may be monoethanolamine.  The potassium carbonate and alkanolamine solutions are regenerated in conventional way in regenerator towers provided with reboiler and condenser.  A heat-exchanger and further cooler is provided in the alkanolamine solution circuit.  A portion of the alkanolamine may be bled off and disstill with caustic soda, and then returned to the process. Residual carbon dioxide may be removed in a third stage by scrubbing the gas in a small tower with aqueous sodium hydroxide solution.
