Title: Device for checking the angles of blades in turbines compressors and like machines
Inventor: MATHIESON GEORGE CAMERON REID
IPC: F01D5/12
Filed: 1951-04-14
Abstract: 714,060. Protractors. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 4, 1952 [April 14, 1951], No. 8740/51. Class 97(3) Means for checking the angular relation of a blade in a turbine or compressor, comprises a calliper device which will fit on the trailing edge of the blade and positively locate itself along the width of the blade, a support therefor permitting the calliper device to turn relatively to the blade about an axis extending along the blade perpendicularly to a fixed line on the machine (the axis of an axial flow machine or the radius of a radial flow machine), so that a line defined by the calliper device is aligned with a line on the blade joining the trailing edge to a selected point on the camber line of the blade, and, for indicating the angle between said line defined by the calliper device and said line on the machine, a protractor device having a scale and pointer, one of which is fixed and the other is attached to and movable with the calliper device. The apparatus shown comprises a plate 1 having a V-notch 1a and a slot 1b in which rides a spring-urged slider 2 pivotally connected by equal links 4 to calliper arms 3 pivoted at 1c to the plate. The latter is connected at 7 to a head 8 journaled in a bearing 9 together with a protractor scale 10 movable relatively to a fixed pointer 11. The bearing 9 is located in a bracket 12 movable in a saddle 13 which is itself movable in an orthogonal direction in a slide 14. In use, the slide 13 is moved so that the feelers 3b of the calliper slide over the trailing edge of a rotor blade and the V-notch 1a fits over the blade edge. To do this, the bracket 7 and the protractor 10 will have rotated about the bearing 9, and the reading on the protractor will indicate the angle of inclination of the axis of the V-notch and, therefore, the angle of inclination of the line in the blade which joins the point on the trailing edge to the point midway between the feelers 3b, relatively to a line parallel to the axis of the V-notch, e.g. the rotor axis. This angle may be checked over the whole length of the blade by moving the saddle 12 along the slide 13.

Title: Manufacture of ª-halogen-butadienes-1, 3
IPC: C07C17/25
Filed: 1937-03-25
Abstract: Halogen-butadienes are produced by splitting off hydrohalogen acid from 1-2 dihalogenated butene while eliminating the halogen-butadiene from the reaction zone at the moment of its formation by means of the vapour of an organic solvent such as an alcohol or pyridine.  The agent for splitting-off the hydrohalogen acid may be alcoholic alkali or pyridine or other tertiary base. In an example 1-2 dichlorbutene-3 is run into a boiling solution of sodium methylate in methanol, to which is added a small quantity of hydroquinone.  A mixed vapour of 2-chlorbutadiene 1-3 and methanol distils off and is fractionated.

Title: Improvements in manifolding apparatus
IPC: B41L5/06
Filed: 1935-03-22
Abstract: 458,587. Manifolding - machines. FORD, Ltd., F. R., and FORD, F. R., Sydenham Road, Small Heath, Birmingham. March 22, 1935, No. 8937. [Class 100 (ii)] A manifolding-machine of the kind in which a roller 7 covered with a mirror script copy coacts with an impression roller 9 mounted in sliding bearings 11 is constructed so as to enable the pressure at each end of the roller 9 to be adjusted independently by screwactuated means comprising a nut 23 threaded on a rod 13 which passes through an abutment and is connected to one end of the bearings. The rod 13 is provided with a threaded end 19 flattened at 24 to prevent rotation of a washer 22 actuated by the nut 23, and which forms the seat of an adjustable compression spring 21 which acts on the end of the rod 13 and tends to move the roller 9 to printing position. The spring 21 bears against an abutment in the form of a crank-pin 20 on a lever arm 14 which tends to rise under the action of a spring 28 on an arm 16 of the lever, the position of the lever 16 being determined by an adjustable crank-pin 17. The crank-pin 20 abuts against an adjustable nut 29 on the screw 19 held in place by a locknut 30, and when the roller 9 is to be moved out of operative position, the end 16, which is flexible, is sprung past the pin 17 and the spring 28 then depresses the arm 16 to an extent controlled by a slot 26 engaging a bent end of the arm 16. The pin 20 there. upon acts on the nut 29 to raise the arm 13. In a modification for use when a rubber roller 9 is used, the spring 21 is dispensed with and a nut similar to 29 arranged between the adjustable nut 23 and the abutment pin 20. Specification 384,771 is referred to.

A tool for reaming punctures in tubeless tyres preparatory to plugging comprises a main cylindrical metal body portion 1 with a handle 1d at one end and tubular portion 1a at the other into and from which extends a probe 2, the body having a coaxial cutting ring 5, 3 at each end facing away from the handle 1d with the ring 5 adjacent the handle being of larger diameter than the body 1 and the ring 3 at the probe end being of smaller diameter than the body 1, and a further cutting ring 4 of the same diameter as the body 1 being provided intermediate the rings 3, 5 to face towards the handle 1d. As shown the probe 2 has a returnbeat free operative end and the tubular body portion la houses a spring 9 which urges an annular member 10, slidable along the probe 2, against an internal shoulder at the tube mouth. The body 1 is formed with two annular constrictions 7, 6 adjacent the cutting rings 4 and 5 respectively, and the outer surface of the body is knurled, milled or helically grooved. In use. correct insertion of the tool is achieved by the probe 2 and the body is twisted right through the puncture until a collar 8 near the handle 1d abuts the tyre surface. On insertion, the cutting edge 3 firstly cores the puncture, with the core being received in the tube 1a against the spring 9, and the outer tyre surface is recessed to a larger diameter by the cutter 5. On reverse twisting withdrawal of the tool the cutter 4 enlarges the puncture hole. Specification 822,348 is referred to.

[Class 20 (iv)] A wall or like structure is constructed from a number of upright supports or studs 1 between each pair of which are arranged a number of slabs 2 sloping rearwardly from their lower to their upper edges and with these edges in overlapping relation, the lower edges of the slabs butting against integral ribs 4 on the supports on the outer side of the wall, while the slabs are supported on their inner sides by retaining means which maintain a close joint between adjacent slabs. In the construction shown in Figs. 1 and 2, the supports 1 are of T-shape and the lower edges of the slabs 2 butt against the outer flanges 4 of the T, the inner faces of the slabs bearing against pins 3 on the supports. The inner face of the wall is constituted by plaster boards 8 which are secured to fillets 6 and cross battens 7, the fillets 6 being attached to the supports 1 so as to bear against the upper edges of the slabs 2. In a modification, Fig. 4, the ribs 4a of the posts are stepped on their inner faces to form a series of shoulders 9 on which the slabs 2 rest. In a further modification the slabs are assembled by passing them horizontally through slots in one support 1 until they contact with the adjacent support. If desired the lower and/or upper edges of the slabs may be bevelled or rebated.
