Title: A shape gauging device or feeler gauge
IPC: B25D5/02
Filed: 1956-05-29
Abstract: 788,280. Shape gauging devices. DECKEL, H., and DECKEL, F. W. May 29, 1956 [June 16, 1955], No. 16575/56. Class 106 (2). A feeler gauge assembly, Fig. 1, capable of being fitted into a rotating shaft 12, such as the spindle of a machine tool, and in which a work contacting feeler 70 is coupled through a linkage mechanism with a rotatable bearing surface 130 so as to be capable of moving said bearing surface axially to and from the spindle 12 to actuate a stationary indicating element or gauge 84, comprises an elastically yielding element carrying the rotatable bearing surface 130 and means acting on this element by which the bearing surface 130 can be adjusted with reference to the axis of rotation. As shown, a taper mandrel 10 may contain three set-screws 132, Figs. 1 and 2, spaced at 120 degrees, and these bear against a recessed part 134 of a bearing-pin 18 for the bearing surface 130. By suitably adjusting these compensating screws the bearing pin 18 can be subjected to a slight elastic distortion whereby the bearing surface 130 will set itself correspondingly with reference to the axis of rotation. Adjustments are made by varying the setting of the compensating screws 132 whilst rotating the yoke 78 carrying the dial gauge 84 until the pointer of this dial gauge no longer shows any deflection. The yoke 78 is supported by the tapered mandrel 10. When a gauging operation is being performed the yoke 78 and its dial gauge 84 may be held stationary by means of a corrugated tube 118 that is secured to the yoke and can be bent to contact a suitable fixed abutment. In a modified construction, the yoke 78 is not mounted on the tapered mandrel 10 but on a bearing bush attached by screws to the bearing-pin 18, there being three compensating screws in the bearing bush acting on the pin 18 to control the setting of the bearing bush with respect to the pin 18. Specification 746,093 is referred to.

Patent GB-560924-A (GB)
Title: An improved manufacture of polymers
IPC: C08F210/12
Filed: 1940-11-26
Abstract: Co-polymers are prepared by mixing an isoolefine and a non-conjugated diolefine of the general formula <FORM:0560924/IV/1> where x is less than 20 and preferably 1-6, cooling the mixture below 0 DEG  C. and preferably below -50 DEG  C. and applying a dissolved Friedel-Crafts type catalyst.  The iso-olefine may be isobutylene or an isoamylene. The preferred diolefine is dimethallyl. Butadiene, isoprene, dimethyl butadiene, cyclopentadiene, pentadiene-1, 3, chloroprene and fluoroprene may be used in addition to form three-component co-polymers.  The products may be vulcanized by treatment with sulphur monochloride or by heating with sulphur and tetramethyl thiuram disulphide.  They may be compounded with carbon black, zinc oxide, stearic acid, lithopone, clay, barytes, ferric oxide, chromic oxide, wood flour, and other cellulosic material.  The products are suitable for making hoses, containers, conveyor belts, and tank linings, for impregnating fabrics, and as insulating materials.  By controlling the conditions of polymerization, oily to viscous co-polymers may be prepared which are suitable as lubricants.  In an example a mixture of iso-butylene, dimethallyl and liquid ethylene was sprayed with a pre-cooled solution of aluminium chloride in methyl chloride.  After one half to two thirds of the reactants had polymerized the catalyst was quenched by addition of methyl alcohol, ethyl alcohol, acetone, water or an alkaline solution such as ammonia, soda or caustic solution.  The white solid co-polymer was then separated.  Dimethallyl is prepared by condensing methallyl chloride in the presence of magnesium suspended in dry ethyl ether. Specifications 513,521 and 523,248 as open to inspection under Sect. 91 are referred to.

Abstract: 613,969. Variable-pitch propellers. CURTISSWRIGHT CORPORATION. June 11, 1946, No. 17401. Convention date, June 11, 1945. [Class 114] In a variable pitch propeller the centrifugal force on the blades is utilised for neutralising the centrifugal twisting moment applied by the blades to the hub. The blade 18 carries a cam ring 24 opposide a similar cam ring 20 carried by the blade socket 14 between which rollers 26 revolve in a cage 36, the cage being rotated by toothed gears 40 engaging toothed flanges 42, 44, on the rings 20 and 24 respectively, the parts being held in contact by a resilient ring 30. The pitch-changing bevel gear 16 engages indexing gear 50 on a core 46 provided on the hub, rotation being transmitted through splines 54, 56, to alter the pitch of the blade 18. Fig. 2 shows a blade and cam rings in the case where five rollers are provided. The centrifugal force E on the blade causes a force Ec/5 acting circumferentially on the camring 24, and the shape of the cam-ring is such that the moment produced by the summation of such forces will neutralise the centrifugal blade twisting moment A.
