Title: Improvements in or relating to lap truing or other machines for generating curved surfaces
IPC: B24B53/065
Filed: 1945-07-18
Abstract: 596,099. Shaping curved surfaces. ABBEY, A. (American Optical Co.). July 18, 1945, No. 18464. [Class 83 (iii.)] [Also in Group XXIII] In a machine for generating curved surfaces on a work-piece, e.g. for trueing cast iron laps used for producing curved surfaces on lenses, wherein the cutting tool and the lap are pivoted for movement in directions mutually at right angles, the radii of the pivotal motions are increased, relatively to those normally obtainable, by the use on a standard machine of an attachment comprising a bracket 38 carrying members 42, 49 having pivots 51, 45 about which the tool and lap move. The standard machine comprises a base 5 with uprights 6, 7 in which a yoke 10 is journalled for oscillation by an adjustable crank 30. The bearing 11 on the yoke 10 normally carries a cutting tool 58 which works on a lap 28 carried in a bracket 20 pivoted at 21 on a slide 18. The slide 18 is mounted on a carriage 17 pivotally mounted on a slide 13 adjustable, in guides on the base 5, by a handle 37. The carriage 17 is moved about its pivot by a worm rotated intermittently by pawl-and-ratchet means 25, 33, a spring and pressed plunger 34 preventing back motion. When the attachment is in use, the adjusting- screw 35 of the slide 18 is withdrawn, and the pivot 45 is connected to the pivot bracket 20 by a telescopically adjustable rod 44, 46, the part 46 being screwed into the bracket 20 which is thus free to pivot about the point 45 as the ratchet 25 is operated. This effects the feeding of the lap 28 relatively to the tool 58, which latter is mounted in an extension 57 of a bracket 56 connected by spaced rods 53 to a yoke 50. The rods 53 are slidably adjustable in the yoke 50 which is pivoted at 51 to the member 49, the latter being adjustable in the bracket 38. The oscillations of the yoke 10 are transmitted to the bracket 56, and thus to the tool 58, by a connecting link 59, the movement of the tool 58 being about the pivot 51. The lap may be mounted on the extension 57 and the tool on the bracket 20 when convex surfaces are to be trued.

Title: Dirigible craft
IPC: B64D39/00
Filed: 1952-07-23
Abstract: 740,696. Aircraft propulsion and control system. CAILLETTE, G. E. July 23, 1952 [July 24, 1951], No. 18674/52. Class 4. [Also in Group XXI] A dirigible craft capable of climbing and descending vertically and remaining immovable in space in a state of stable equilibrium without the use of a sustaining rotor comprises propulsion means developing a resultant thrust applied to the craft and angularly adjustable with respect thereto and control means responsive to direction-sensitive means whereby said resultant thrust is constrained to keep a predetermined direction in space and is controlled in such a manner that its line of action intersects a predetermined axis of the craft's body passing through the centre of gravity thereof, at a point located ahead of said centre of gravity, in the direction of action of said resultant when said axis is not parallel to said predetermined direction. An aircraft has a propulsion unit Co arranged so that the axis of thrust R, when displaced from coincidence with the longitudinal axis Z, always intersects the axis at a point O located ahead of the centre of gravity G in order that the craft may be inherently stable. In order that a predetermined heading may be maintained a pick-up device De (which may be gyroscopic) is set to a direction D and it controls the direction of thrust R by the mechanism shown in Fig. 7. Power is derived from a generator Ge and device De comprises two potentiometers r1 and r2 which may be inserted, by a switch I, in a circuit comprising two relays Rx and Ry and two servo motors Sx and Sy adapted to control the angular position of the propulsion unit Co. The movements of the servomotors are transmitted to the unit Co through a link Pi of variable length which may work as a damper and as a follow-up device. A manual control L may be provided to override the device De to control the propulsion unit. It may be located in the aircraft and may comprise potentiometers r3, r4 connected to the relays Rx and Ry or it may be remote from the aircraft and connected to the relays by a radio link. The member L may be connected directly to the propulsion unit. A further control system (Figs. 15-22, not shown) is described for a plurality of propulsion units in which a mechanism similar to that of Fig. 7 controls a universally mounted plate which inturn operates a plurality of plungers connected to potentiometers controlling the operation of servo motors acting directly on the propulsion units. An arrangement is described also for adjusting the angle of the core of the propulsion gases. Further embodiments describe arrangements for piloted aircraft and guided missiles. The number of propulsion units is usually at least three but a control system and installation for two only is described.

Title: Pressur*e limiters for a compressed-air braking system
IPC: B60T17/18
Filed: 1977-05-05
Abstract: In order to take account of the changing pressure requirements such as occur in tractor vehicles, which in solo operation work with a higher pressure, for example of 9.5 bar, and for which only a lower pressure of 7.5 bar (normal pressure) is provided when the trailer is attached, the pressure limiter is inserted into the through-line of the brake system (114, 115). The pressure limiter has a passage with a valve (138, 139), the controlling piston member (137) of which is coupled to a servo piston (141), by means of which the switching point of the pressure limiter (130) can be adjusted. A coupling piece (142) between servo piston (141) and piston member (137) is designed as a plug-in coupling so that a secondary effect caused by the limited pressure also acts on the servo piston (141). A seal (148, 149) of the servo piston (141) is divided into two sections and the gap (151') can be connected by way of a non-return valve (150, 151) to the outside air with a cylindrical piece of hose (152) as closing element. <IMAGE>
