Title: Device for mounting tubes in apertures in a wall
IPC: B21D39/20
Filed: 1960-07-08
Abstract: 890,243. Jointing by tube expanding; flanging. SVENSKA FLAKTFABRIKEN A.B. July 8, 1960 [July 9, 1959], No. 23922/60. Class 83 (4). A method of mounting tubes in apertures in a wall is characterized in that the mounting is achieved by a partial expansion of the tube at the mounting point and is carried out by means of a body of elastic material, preferably of rubber, being inserted into the tube end, said body being forced by axial compression to expand radially and thereby expanding the tube end to press against the peripheral surface of said aperture. The apertures may have bordered flanges or collars against which the tubes are to be pressed. A rubber sleeve 9 on a bolt 4 is compressed axially, to expand a tube end placed thereover between a head 4a on the bolt 4 and a shoulder plate 1 held by a hand grip 2, the bolt being moved axially by a nut 5 threaded on its end 4b. The bolt 4 is prevented from rotating by a screw 7 engaging a slot 8 in the bolt. A washer may be disposed between the sleeve 9, and the shoulder plate 1 has a curved edge along which the tube end is forced to slide on the expansion of the tube.

Abstract: 299,953. Broadbent & Sons, Ltd., T., and Broadbent, B. L. Sept. 13, 1927. Driving.-A centrifugal or similar machine b on a vertical spindle a is driven by an electric motor c below the machine, and means are provided to prevent lubricating oil from reaching the motor. The cover plate f of the motor casing g has an upwardly extending boss f<1> containing the roller or other bearing d, the inner race of which is held between the sleeve k and the nut j. A recess m is formed in the boss beneath the bearing, and the lower end of the sleeve k is undercut to form a circumferential knite edge k<1>. A cover o encloses the bearing. Lubricant is introduced through the passage a<3> and after passing the bearing collects in the recess m: if any passes down the outer surface of the sleeve k it is thrown centrifugally from the knife edge k<1> into the chamber f<2>, passes down the wall f<3> and the web h<1> to the outlet n. The upper end of the wall f<3> is provided with a trap to deflect any oil which may pass down inside the sleeve k. A cap s. secured to the base r of the motor casing, fits closely round the lower part of the rotor boss. If oil works upwards ,from the bearing e it is thrown off the rotor boss and passes down the inner surface of the cap s to the holes r<1>. Removal of the cover o, the nut and the bolts p, will allow the cover plate f and bearing d to be withdrawn. The rotor c with the bearing e can then be removed.

Abstract: 141,011. Post, H. A. von, and Savage, W. April 2, 1919, [Convention date]. Sliding - jaw wrenches.-A wrench is constructed so that the grip of the jaws increases as the resistance to turning of the nut &c. increases, the jaws slip over the corners of the nut &c. on the back stroke of the wrench, and the jaws are automatically set normally to fit the largest nut &c. for which the wrench is intended. As shown, the sliding jaw e is operated by a tooth g on a handle h pivoted to the head b carrying the fixed jaw c. Springs j, k secured to the handle bear on opposite sides of the head b and normally hold the parts so that the jaws c, e are set for the largest nut for which the wrench is intended to be used. By pressing the spring k towards the handle h, the jaws may be moved towards each other as shown by the dot-and-dash lines to fit nuts smaller than the maximum size. The dotted lines show the position the jaws assume on the back stroke of the handle allowing the jaws to slip past the corners of the nut.

In an aircraft designed for vertical flight and utilizing gas produced by a machine having a casing supporting a rotating part, a directioncontrol device comprises means for producing a control movement about a first axis of the aircraft, means for pivotally mounting the casing about a second axis perpendicular to the first axis, means for urging the casing to a neutral position, and means for applying the gyroscopic couple generated by the rotating part and pivoted casing when the aircraft moves about the first axis, to means for controlling the control means in such a manner as to counteract such movement of the aircraft. The jets of two identical turbo-jets 1, 2 which are pivoted to the aircraft structure about axes XX<SP>1</SP>, YY<SP>1</SP> parallel to the roll and pitch axes respectively of the aircraft, are deflected by means of compressed air supplied to diametrically opposite sectors 13 and 14, 15 and 16, via gates 5, 6 and pipes 9 and 10, 11 and 12 respectively, gates 5, 6 being controlled from the control stick by linkrod systems 3, 4. When the control stick is operated, either or both of the engines will be angularly displaced and, by virtue of their gyroscopic actions, will react on the control stick, by means of couplings 17 and 19, 18 and 20, so as to oppose the action of the latter on gates 5 and 6 and thereby create restoring couples to stabilize the aircraft Double-acting spring systems 1b, 2b and 1c, 2c tend to keep the longitudinal axis of each turbo-jet in a central position

Title: Improvements relating to the steering of road-vehicles
IPC: B62D17/00
Filed: 1939-08-28
Abstract: 534,227. Mounting steerable wheels on motor vehicles. ROVER CO., Ltd., and IVERSEN, P. A. SCOTT-. Aug. 28, 1939, Nos. 24648 and 24649. [Class 79 (v)] The steering pivot 19 of an independently - sprung steering wheel 11 is arranged to have a predetermined "camber projection " 18 and passes behind the wheel centre so that whilst its castor angle is greater than usual the resulting " castor projection" 22 is approximately the same as that normally arranged. The "projections " referred to are the respective distances at which the steering pivot axis intersects the ground to one side and in front of the vertical line or diameter passing through the central plane of the wheel. The result is that the castor effect is normal for straight running, but when the vehicle is rounding a curve and the outer steering wheel rises relatively to the frame the usual increased castor action, which causes heavy steering, is counteracted ;by a force couple due to the reaction of the ground on the wheel. In the construction shown the wheel is connected to the frame by the independent spring suspension described in Spec:- fication 518,597, [Group XXXII], and comprising upper and lower transverse links, 13, 14, a coil spring 15 acting on the lower link, and a radius or torque rod (not shown) fixed to a bracket 12 and extending rearwardly to a ball joint connection with the frame. Specification 2705/1900, [Class 79], also is referred to.
