Title: Devices for radius truing of grinding wheels
IPC: B24B53/065
Filed: 1953-04-02
Abstract: 716,580. Trueing grinding wheels. JONES & SHIPMAN, Ltd., A. A., and HOULDSWORTH, J. April 2, 1953 [April 2, 1952], No. 8398/52. Class 60 A device for trueing a grinding-wheel 14 includes a holder 7. Fig. 1, incorporated in a system of pivotally - interconnected links 4 which are operable in unison to impart a rocking movement to the holder and to move a diamond 8 carried thereby in an arcuate path. The two links 4 are connected to cranks 3 mounted in anti-friction bearings in a base 1 and oscillated by a handle 13 to move the diamond. The latter is adjustably set with the aid of a stirrup 12 and in accordance with the radius required on the grinding wheel. Caps and sleeves enclose the bearings of the cranks 3. In a second embodiment for trueing both concave and convex wheel profiles, the diamond 50, Fig. 4, is mounted in a link holder 47 pivotally connected to links 44 and 45 which are in turn pivotally connected to two triangular. cranks 42, 43 rotatably mounted in a plate 39, Fig. 5. The latter is bodily displaced in an arcuate path corresponding to the wheel profile while the cranks are simultaneously rotated about their pivots 40, 41 to vary the inclination of the link 47 in accordance with the position of the diamond. This is accomplished by the mechanism shown in Fig. 5 which comprises two eccentric pins 35 adjustably clamped to rotary members 23, 24 each provided with two pins spaced at an angular interval of 90 degrees and connected by links 27 and a plate 28 to a handle 29, and two toothed bushes 46 cooperating with toothed segments on the cranks 42, 43. When the handle 29 is oscillated between two stops (not shown) the pins 35 cause the bodily movement of plate 39 while the consequent relative movement between the bushes 46 and the cranks causes the latter to rotate. The eccentricity of the pins 35 determines the radius of the wheel profile while their setting at either side of the centre of rotation determines whether the profile is convex or concave. The bearings are enclosed and a flexible dust-excluding member 49 is also provided.

Title: Improvements in or relating to accelerometers
Inventor: BARNES JEFFERY WALTON
IPC: G01P15/18
Filed: 1948-03-22
Abstract: 791,827. Electrically-operated accelerometers. MINISTER OF SUPPLY. April 22, 1949 [March 22, 1948], No. 8410/48. Class 40 (1). In an accelerometer having a mass mounted so that small movements of the mass in a given plane are used, via an electrical pick-off means, to control the magnitude of an electrical restraining force which restores the mass to its former position, and is therefore a measure of the acceleration causing the movement, the resultant force acting on the mass due to the mounting is reduced or eliminated by rotating the mass about an axis normal to the given plane and passing through the centre of gravity of the mass. The speed of rotation is adjusted so that the sinusoidal variations of the force due to the mounting do not prevent a mean value corresponding to the actual acceleration being obtained. Pick-off means employed to produce electric signals corresponding to the movements of the mass in the given plane may be inductive, capacitative, or photo-electric, the signals being amplified and used to control a restraining force, such as an electromagnetic force. In Fig. 1, which shows an elevation of one form of apparatus, Fig. 2 being a sectional plan view on the line II-II, the mass 12 is a hollow cylinder having flanges 13, 14 and 15. Three parallel fairly stiff wires 16, 17 and 18 are secured to the flange 15 at equidistant points, the lower ends being secured to a wheel 19 which is mounted by journals on the fixed pillar 22, and has teeth whereby it can be continuously rotated by the worm 23 driven by the motor 24. The upper flange 13 carries, or is constituted by, a concentric slab winding 25 which at diametrically opposite parts extends between the polepieces 26, 26a of a permanent magnet 28 on the one hand, and the segmental polepieces 29, 29a of a member 30 of magnetic material on the other. The lower flange 14 has a similar slab winding 32 which at opposite parts defining a diameter at right angles to the inter-pole parts about the winding 25, extends between further segments 33 and 34 of the member 30 and the polepieces 35 and 36 of the magnet 31. An inverted cup-like member 37 carries insulated capacitative plates 38, 39, which are linked electrically to the winding 25, and other capacitative plates 40 and 41 which cause indirect excitation of the winding 32. With the mass 12 rotating, any acceleration in a plane normal to the axis of rotation will alter the capacity between the mass and one or both pairs of plates, one or both windings then being excited and tending to make the mass 12 concentric with the pillar 22. The mean of the restraining force will be a measure of the acceleration.

Needles 3 have grooves 5 engaged by hooks 7 at the upper ends of jacks 6 whose lower ends have slots engaging the circular heads 11 of jacks 10. Jacks 10 are carried in the tricks 13 of a jack cylinder 12 coaxial with needle cylinder 1. Four pattern drums 18A, 18B, 18C, 18D rotate synchronously with cylinder 12 and have tricks 19 of the same pitch as tricks 13 and carrying jacks 20 with butts 21 for controlling the lower jack butts 17 of the jacks 10. The drums rise or fall one step to change the jack butt operating on butt 17 every time that the cylinder rotation reverses. Needle cams are provided which operate during normal and reverse knitting. Between pattern drums 18A, 18B, 18C, 18D are mounted brackets 31 carrying pickers 36, 37 whose ends 38, 39 face outwards along the path of butts 14 of jack 10. Normally these pickers are biassed by springs 40, 41 against stops 42, 43 so as to be out of action. Levers 48, 49 pivoted respectively adjacent pickers 37, 36 carry cams 50, 51 and are connected together at their ends by a spring 54 which biasses them against a sector cam 44 movable between two positions when the rotation of the cylinder 1 reverses. When the wide part of sector cam 44 engages e.g. lever 48, a cam at the other end of lever 48 is pushed into the path of cylinder jack butt 15. Engagement of a butt 21 with a butt 17 tilts the associated jack 10 so that butts 14, 15 project. In operation, moving clockwise, Fig. 3, the jack 10 of the first selected jack engages the end of picker 36 and rotates it to full line position and thus pushes the butt 14 inwards and the associated needle while having received the yarn does not knit while the succeeding needles do knit.

Abstract: 418,212. Aircraft with rotary wing systems. COATS, A. G., and RUTHERFORD, W. V. D'A., Gloucester House, Park Lane, London, HAFNER, R., 47, Mantlergasse, and NAGLER, B., 59, Rennweg, both in Vienna. March 21, 1933, No. 8555. [Class 4.] In a helicopter or auto-rotative wing aircraft having associated blade flapping-means and blade incidence-changing means, the latter of which may be controlled from the cockpit for varying the angles of incidence of the blades either as a whole or differentially, each blade is supported by flexible bracing at a distance from its root and guided at the root by a swivel or like bearing 11 on the rotating structure so that centrifugal force relieves the pressure on the root of the blade and enables its angle of incidence to be altered without friction. In one form, a control column 2 is universally mounted at the centre of the wing system by means of a ball-joint and has rotatably mounted thereon a spider-member 5 connected by joints 6, 7 to radius rods 8 on the blades 1 of the lifting-screw. The blades are normally set at a dihedral angle, and each blade is braced by bracing 9 pivoted by links 10 to a frame 12 carried by one port 13 of a ball race, the part 13 being driven by an engine which may be declutched. A member 17 carrying the seating for the ball joint is threaded to facilitate axial adjustment from the cockpit in a tubular member 15 carried on the aircraft body. The length and position of the rods 8 may be varied so as to give any desired ratio between amplitude of flap and change of angle of incidence and the rods 8 may be disposed and hinged to the member 5 on the side of the bearings 11 remote from the wings. A lost-motion device may be embodied in the mechanism so as to allow the blades to flap a predetermined amount without altering their angle of incidence and the lifting-screws may be provided with any number of braced and pivoted blades. Specification 385,101 is referred to.

Abstract: 889,503. Automatic couplings. BUSCH, W., and FRIEDERICHS, H., [trading as BERGISCHE STAHL-INDUSTRIE REMSCHEID]. March 11, 1960, No. 8656/60. Class 103(5). An automatic coupler head 11, Fig. 1, slidably -keyed to a draw-bar 18 has journailed therein a rotatable bush 12 in which is slidably but eccentrically mounted a non- rotatable coupling bolt 24, and the bush is so connected by links 15, 16 with the drawbar that when the head is coupled up to a similar head, an applied traction load moves the bar 18 in the relative direction X and rotates the bush 12 in the direction Y to cause the bolt 24 to move slightly to the left and take up any wear between the bolts. As the wear is taken up by engagement of the bolts 24 on mating couplers, the head 11 in Fig. 1 moves to the right relatively to the engaged bolts so that the butt faces 25 of the couplers are forced together. In the embodiment of Fig. 3, shown in the uncoupled position, when the head is buffed on coupling up it moves in the direction W relative to the draw-bar 18 so that the bush 12 is rotated in the direction Z and moves the bolt to the right. The noses of the mating coupler bolts then engage one behind the other, but there is play between them. The buffing force assisted by the spring 30, however, keeps the butt faces 25 in contact. When a traction force is exerted, the bush 12 is rotated as in the previous embodiment, the bolts will contact one another again, and the heads 11 will be forced together. During any interval between the cessation of a buffing force and the exertion of a traction force the springs 30 of the engaged couplers force the heads 11 together, and at no time is there space between the butt surfaces 25. The links 15 and 16 may be replaced by chains, cables, or gear transmission.
