Title: Improvements relating to disc brakes
Inventor: HAMBLING STEWART KEVERN
IPC: F16D55/224
Filed: 1965-04-13
Abstract: 1,136,774. Releasable fastenings. GIRLING Ltd. 6 April, 1966 [13 April, 1965], No. 15592/65. Heading E2B. [Also in Division F2] In a spot-type disc brake comprising a hollow first piston 35 adapted to directly apply one friction pad assembly 22 against one side of a disc 11 and a second piston 36 working within said first piston and adapted to indirectly apply another friction pad assembly 19 against the other side of the disc through a yolk 14. On supplying hydraulic fluid through an inlet 37 of the second piston, mechanical handbrake actuation of the brakes is effected by cable-operated bell-crank levers 38, 39, the movement of said levers being transmitted to the first piston through one-way clutches. Each clutch comprises a wedge member 40 spring loaded against a shoulder 42 of the yolk and a ball 44 interposed on inclined surface 43 of the wedge member and the exterior of the first piston, said ball locking the wedge member to the first piston when the wedge member is axially moved on actuation of the bell-crank levers. In a modification, the diametricallyopposed wedge members are replaced by ring of corresponding cross-section slidablymounted on the first piston.

Abstract: 564,478. Colour testing apparatus. LANGLEY, T. W., and TECALEMIT, Ltd. Nov. 5, 1942, No. 15668. [Class 97 (i)] Apparatus for comparing the colours of liquids in cylindrical tubes with reference colour filters comprises a casing divided by a partition 4 into front and rear compartments 2, 3, at least one tube-holder 5 in the front compartment, aligned viewing apertures 8 in the front wall and the partition 4 having one edge respectively in front of and behind the axis of a tube in the holder and having their common central axis tangential to one edge of the tube, a lightadmitting opening 24 in the back 20 of the casing, which opening is situated at a distance behind the tube approximately equal to the tube diameter and extends from a position approximately behind the edges of the apertures 8 situated on one side of the tube to a position lying beyond the other edges by a distance at least equal to the tube diameter, together with a number of reference colour filters 15 carried by means by which they may be selectively moved to appear adjacent the part of the tube under observation. The arrangement and dimensioning of the light-admitting opening is found to cause the light transmitted and refracted through the liquid in the cylindrical tube to appear as though transmitted through a layer of uniform thickness. In the form shown, the casing is pivoted to a stand 28 and contains two tube holders 5, 7 in the form of vertical channel members open at the back and having the parts of their walls between the pairs of apertures 8, 9 respectively cut away. The light-admitting apertures 21, 22 in the rear wall are covered by ground glass plates 23, 24, and a pivoted mirror 29 reflects light through them. A disc 12 rotatably mounted in the rear compartment is formed with six apertures, in each of which are held by clips two colour filters 14, 15. The filters 14 may be selectively positioned to appear in the right-hand half of the apertures 9, and the filters 15 may be similarly positioned in the aperture 8. Sockets 30, 31 for sight tubes or magnifying viewers are provided on the front of the casing. A modification is described which has holders for four tubes, and in which the filter disc has nine apertures, each containing four filters cooperating respectively with the four tubes.

Abstract: 844,513. Steam irons. SUNBEAM CORPORATION. May 19, 1958 [Sept. 30, 1957], No. 16049/58. Class 138 (2). A steam iron, comprising a sole-plate having a steam-generating cavity therein, has a liner fitting into the cavity and removable therefrom, the liner in use being expanded to force the walls thereof against the walls of the cavity. As shown in the Figure, the sole-plate 15 has a cavity 44 and a U-shaped heating element 14 surrounding the cavity on three sides. The cavity contains a thin-walled cup 21, e.g. of copper or steel foil, into which has been compressed wool of a non-staining resilient metal such as stainless steel surmounted by a lid, also of metal foil. Cap 32 of the iron, when retained in place by lugs 36, compresses the cup and forces the walls thereof against the walls of the cavity. Preferably a disc of solder having a melting- point below the boiling-point of water is placed between the bottom of the cup and the floor of the cavity to improve heat transfer to the interior of the cup. Tap water is supplied to the iron from an external reservoir, through tube 31 and through thick-walled tube 33 in a bore 29, to the steam-generating cavity. Steam passes through holes in the side walls towards the rear of the iron, through annular groove 67 in the sole-plate, and through passage 68 to steam-distributing channels 69 in the base of the sole-plate. The cup collects deposits formed on evaporation of the water and is readily replaced by a new cup.
