Abstract: Cementitious material as used in the building trades such as plaster of Paris, Keene's cement, and Portland cement is reinforced by means of fibrous glass which has been pretreated with hydrofluoric acid gas to roughen the surface.  The glass may be in the form of thread or in cloth form, the weave being similar to that of hessian scrim.  It may be added before or during moulding.  Wood wool slabs, clinker, breeze blocks, cork, paper, timber, vermiculite, sand and oxide pigments may also be added.
Patent GB-328389-A (GB)
Title: Improvements in or relating to change-speed devices for variable speed gear-boxes
Filed: 1929-03-15
Abstract: 328,389. Hingston, W. H., and Humfrey-Sandberg Co., Ltd. March 15, 1929. Controlling variable-speed gearing. - A new speed is preselected and, thereupon, means for effecting the change is operable only when the gear-box has been isolated by the disengagement of engine and tail-shaft clutches. Thus, in Fig. 13, the preselector is a distributing valve 61 which is turned, and which is geared so as to turn a cam cylinder 24 with it. This cylinder operates one of four pins 37 so as to release a selected pivoted catch such as 32. There are two gearoperating selector bars 47, 48 and one of these is now free to make the selected movement. On depressing pedal 49, engine and isolating clutches are first released, and then a valve 60 is opened so that one of four spaces in two cylinders 50 is connected to engine suction. The appropriate piston power stroke follows, completing the change. In a form shown in Figs. 1 and 2, a single suction cylinder 11 is used. Preselection is effected by turning shaft 23 of cam drum 24. The drum 24 through one of four pins such as 37 and pivoted catches such as 32 leaves one of two levers 7, 8 able to make a selected movement. The levers 7, 8 engage the interlocked selector bars 47, 48 and are secured to the side gears 4, 5 of an epicyclic train. The planets 6 of this train are carried by a rock-lever 9 jointed to two stopbars 16, 17, which are guided to slide in holes 14 in a flange on cylinder 11. The preselection also, through a pinion 22, turns a disc 20 so as to bring one of four holes 41 - - 44 opposite the end of one of the bars 16, 17. In Fig. 1, hole 41 registers with bar 16. As before, a pedal is depressed, which first isolates the gear-box and then connects cylinder 11 to suction at 45. Piston 18 moves to the left against spring 19, and disc 20 engages the end of the other stop bar 17. Bar 17 moves to the left and bar 16 passes clear to the right, so that lever 9 is rocked, and the only movement left possible by the locking device is effected.

Title: Improvements in or relating to porous materials
Inventor: NAYLOR BEATRICE
IPC: B01D39/10
Filed: 1950-04-06
Abstract: 697,908. Making porous material. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 6, 1951 [April 6, 1950; June 3, 1950], Nos. 8757/50 and 14040/50. Class 83 (ii). [Also in Groups I, VIII and XXVIII] Porous material comprises wire-like members laid up in a single ply or layer, or in two or more superposed plies or layers, the or each ply being one member thick, the ply, at least in the case of a single ply material, having adjacent members contiguous with one another, and being subsequently deformed so as to produce pores between them through the ply or each of them and joined one to another. In a particular embodiment soft iron wires 1 of 16 S.W.G. spaced by wires 2 of 36 S.W.G. are stacked in plies and lightly rolled to deform the wires, Fig. 2, forming pores 3. Copper foil sheet is then laid on the stack and the whole placed in a controlled-atmosphere brazing furnace. After brazing the stack is coldrolled and then rebrazed. The pores are then reduced to the required size by further cold rolling, Fig. 3. In a modification, a single ply is formed by feeding members through rollers which crimp and guide them in spaced relationship, thereafter subjecting them to a tacking operation as by gluing or brazing, before proceeding with the brazing and other steps aforementioned. For the production of multi-ply sheets the plies, with members of adjacent plies in angular relationship are fed through cold rolls and tacked. In a further modification wire-like members are fed on to a rotating frame, which is rotated about a different axis after each revolution so that the members in adjacent plies will be in non-parallel relationship. The assembly thus formed is brazed and cut along the sides of the frame, each side of the assembly thus constituting a unit compact upon which further deformation or brazing processes may be carried out if required. A porous walled tube, Fig. 5, comprises several layers of a ply consisting of alternate round and half-round section 16 S.W.G. mild steel wire, the half round section wire being twisted about 8 times to the inch, and the assembly brazed and rolled. Where the members are of synthetic resins or rubbers the joining may be arranged to take place during and by virtue of the curing operation. The material is of use in making turbine and like blades, or parts of turbines, com. pressors, combustion apparatus, heat exchangers, and other components of gas turbine plant, de-icing and boundary-layer removal plant in aircraft, and porous walled fluid ducts.

Electrode furnaces. -In a furnace having an upper electrode for each phase of a supply system, and oppositely - arranged hearth electrodes H<1>-H<3>, energetic heating of the body of molten material is produced, when required, by switching out or raising one upper electrode E<2> and replacing it by the hearth electrodes, which are connected to the same point of the supply system. When surface heating of a quiescent bath is required, all the upper electrodes E<1>-E<3> are brought into action, and the hearth electrodes may be either left in circuit or switched out. The hearth electrodes may be covered with resistance material.

Title: An automatically operated change speed gear
IPC: B62M9/08
Filed: 1922-03-28
Abstract: 194,161. Lechenaux, L. J. March 28, 1922. Variable-speed gearing of the kind comprising eccentrically-displaceable discs such as 1, 7 connected by pawls or hooks such as 5 is rendered automatic. In the application to a bicycle shown in Figs. 4 and 5, the disc or rim 1 is driven by a chain 2 from the pedal axle 4. This disc 1 turns upon a non-revoluble boss 12 supported on a spring-pressed lever arm 15. The hooks 5 are pressed by springs 10 against the toothed edge of the disc 7, which is secured to the hub of the road wheels 8. A spring 18 tends to hold the disc 1 in the position of maximum eccentricity transmitting the highest speed. As the tension in the chain 2 increases, the spring 18 yields, the disc 1 moves towards the disc 7, and the ratio decreases. A jockey pulley 20 is held in position by a detent 26 which is released by backpedalling. In a modification, the controlling spring is damped by fluid adjustably throttled. In the case of sub-normal speeds, the teeth of the disc 7 are screened by masks 33, 34, Fig. 6, so as to use the hooks 5 when moving at the speed required. The opening between these masks is controlled automatically by pins 35, 36 adapted to move in fixed grooves. In a form shown in Fig. 8, a screen 37 is formed so as to yield speeds above and below normal, and nodrive. Applications to machine tools and to hoisting-apparatus are mentioned.
