Abstract: 938,977. Disc brakes. D.B.A. S.A. Nov. 7, 1961 [Nov. 10, 1960], No. 39846/61. Class 103 (1). A disc brake comprises a housing including two spaced calipers 18, 20, Figs. 1 and 3, straddling the disc 10, pivotally mounted on a fixed axle 14, and interconnected by first and second friction pads 26, 28, and actuating means adapted to move the pad 26 into engagement with the disc and to cause the calipers to pivot about the axle 14 to bring the pad 28 into engagement with the disc. The portions of the calipers at each end of a recess 30 engage in notches formed in the sheet metal support of the pad 28. The recess may present a convex form in order to apply pressure to the pad at a point which is displaced as the pad wears to ensure a correct application. Preferably the recess is of concave form and a half-moon piece 36 is interposed between the back of the pad and the bottom of the recess. At least the end portions of the plate support of the pad 28 are bent back. The pad 26 which is connected to the calipers 18, 20 substantially in the same manner as pad 28 slides in a recess 31 and has its sheet-metal support pierced by a central hole 38 through which is fitted a terminal projection 40 of the piston 42 Only the periphery of the piston 42 engages the pad 26 so that a large swinging moment is created as soon as the piston no longer presses flatly which tends to turn the cylinder block 24 around shafts 44 which extend through holes 46 in the calipers 18, 20. The coupling between the cylinder 24 and the calipers is assured by friction washers 48, spring washers 50, and snap ring 52. An automatic wear compensating device 55 is interposed between the piston 42 and a pin 56. In another embodiment, Fig. 4, the cylinder block is rigidly fixed to the calipers, the pressure of the calipers on the pad 28<SP>1</SP> is direct and the wear compensating means is replaced by a simple friction ring. A mechanical brake actuator is formed by a cam-lever 58 which turns freely on one of the shafts 44, Fig. 3, and a friction washer is interposed between one caliper and a shoulder on that shaft. A slot 62 is made in the friction washer into which penetrates a pin 64 carried by the lever 58. If the amplitude of displacement of the pin 64 exceeds the play in the slot 62 the friction washer is rotated so that the return of the lever is limited to the clearance between the pin and the slot. If the cylinder is adapted to turn with respect to the calipers as in Fig. 3, the mechanical actuator would take the form of a double cam lever having a branch either side of the cylinder. In a further embodiment, Fig. 6, the disc 10<SP>11</SP> is secured at its outer periphery to the driving member. Spring blades 70 intended to suppress vibrations are fixed to a caliper by screws 72 and possess two curved projections 74 each penetrating into the notch 3211 and interposed between the pad and the caliper.

Abstract: 1473838 Laminates KARL KROYER ST. ANNE'S Ltd 26 July 1974 [23 Aug 1973] 40074/73 Heading B5N A dry-laid web or cellulosic fibrous material is moistened and formed into a consolidated web by dry-laying cellulosic fibres to form a mat upon a supporting surface, forming a sheet of aqueous cellulosic fibrous stock, combining the sheet of stock with the mat and consolidating the combination of dry-laid fibres and aqueous stock by subjecting it to heat and pressure. The stock may be directed in sheet form on to the mat from a slice and the combination consolidated by passage around a heated cylinder having pressure rollers co-operating therewith. Alternatively the stock may be formed into a web by a wet-forming technique on an auxiliary forming band before it is combined with the mat. The stock may have a solids content of 10-15% by weight and the moisture content of the combination may be about 30% by weight. In Fig. 2 dry cellulosic fibres mixed with 5% by weight of starch binder are conveyed in an air stream from dispenser heads 11 on to the upper surface of endless wire supporting surfaces 10 to form a mat thereon. A wet-laid fibrous web formed on auxiliary forming wire 21 in cylinder mould device 20 is transferred at roll 22 on to the mat with the aid of vacuum box 23 and the combination consolidated by pressing against consolidating cylinder 15 using pressure rolls 16. The consolidating cylinder may have a temperature of at least 150 F. and each pressure roll may be applied with a pressure of at least 150 p.l.i. In an alternative arrangement the wet-laid fibrous web may be transferred to the consolidating cylinder before the dry-laid fibrous web is applied thereto. When multiply products are required two units of the type shown in Fig. 2 may be employed in back-toback relationship so that the wet-laid webs form the outer liners of the product and the dry-laid webs form the inner plies.

Title: Preparation of arylboronic and diarylborinic acids and esters and anhydrides thereof
Inventor: ROSINGER HERBERT PAUL
IPC: C07F5/02
Filed: 1959-11-30
Abstract: Arylboronic acid esters or diarylborinic acid esters or mixtures thereof are prepared by reacting an arylmagnesium chloride with a boric acid triester in a reaction medium comprising an excess of the aryl chloride from which the arylmagnesium chloride is derived, or a hydrocarbon.  The reaction product can be hydrolysed with aqueous acids to give the boronic and borinic acids.  The acids may also be heated with a solvent capable of forming an azeotrope with water to give the anhydrides. The arylmagnesium chloride is prepared in known manner by heating together magnesium and an aryl chloride which may contain substituents such as alkyl, alkoxy, aryl, aryloxy, alkaryl or nitro groups or halogen atoms.  The diluent used in the reaction is preferably the aryl chloride but solvents such as toluene, xylene, tetrahydronaphthalene or aliphatic hydrocarbons boiling above 100 DEG C., may be used.  The arylboronic acid ester is preferentially formed by using an equimolar amount or slight excess of the ester, adding the arylmagnesium chloride to the ester and operating at low temperatures, preferably below -30 DEG C. The diarylborinic acid ester is preferentially formed by using the arylmagnesium chloride and ester in a 2 : 1 molar ratio, adding the ester to the arylmagnesium chloride and heating the mixture, preferably to 130 DEG -250 DEG C.  The process may also be carried out by heating the magnesium, aryl chloride and ester in the reaction medium, preferably to at least 130 DEG C.  In examples the preparation of phenylboronic and diphenylborinic anhydrides, diphenylborinic acid and its 2-aminoethyl ester is described.
