Abstract: 760,992. Copy-milling. GARRETT COBPORATION. May 27, 1954 [June 17, 1953], No. 15686/54. Class 83 (3). A milling-machine for generating curvedbladed turbine-wheels &c., comprises a number of carriages 18, 21, 25 movable in different directions by separate motors, one of which, 25, carries a cutter 27 and switches 29, 30 for controlling the motors, and each having a feeler 29a, 30a and a chuck 89 driven by a control-motor 36 which also drives a pattern 59 engaging one of the feelers. The carriage 21 carries an adjustable support 31 on which is mounted the hub-form pattern 33. The second pattern 59 is mounted on a shaft 58 carried in an angularly-adjustable yoke and connected by adjustable strap-mechanism 54, 55 with a shaft 51 rotated by the electric, hydraulic or pneumatic-motor 36 through reduction gearing 38, a shaft 39, a universal joint 40 and wormgearing 52, 50. The worm may be moved angularly out of contact with the wormwheel by a manually-operated screw 47. The work 90 is secured in the chuck 89 on the shaft 51 by clamps 92 and is indexed manually by releasing an indexing-plunger 95 by an eccentric pin 97 turned by a knob 99. The knob is moved axially, after indexing, to engage locking-pins thereon with holes in the chuck body. Initially, the support 31 is adjusted to position the work 89 relatively to the cutter 27 as at G. The yoke carrying the shaft 58 is then adjusted to position the rotatable flat template 59 and a fixed template 107 in a plane at right angles to the feeler 30a as at D, the starting-position on the template 59 being indicated by an index mark M. Lateral movement of the feeler 30a allowed by rotation of the template 59, and vertical movement, allowed by horizontal movement of the template 107, actuates the switch 30 to control the movements of the carriages 25 and 21 by screws 26, 23. Axial movement of the feeler 29a, from an initial position E, caused by movement of the pattern 33 towards it, actuates the switch 29 to control the carriage 18 by screw 22.

Title: Improvements in radio system and method
IPC: H01Q19/13
Filed: 1929-05-21
Abstract: 312,189. Kolster - Brandes, Ltd., (Assignees of Kolster, F. A.). May 21, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Directive signalling; aerials; fading, preventing; modulating systems.-A concentrated beam of energy is emitted by two or more short aerials 12, 13, Fig. 1, located at the focal centre of a parabolic reflector 11. The two aerials are preferably arranged at right-angles to each other, and are also inclined so as to lie substantially - parallel with the surface of the reflector. A similar system is used in reception. The radiated energy has both vertically and horizontally polarized components, which helps to overcome the effects of fading. In the arrangement shown in Fig. 3, a single aerial 22 is formed with a central inductance 23 coupled to an inductance 27 in series with a high-frequency source 28. The aerial 22 is spun bodily around its supporting spindle by a belt 26 at an audible frequency. The predominant plane of polarization is correspondingly rotated and gives rise to an audible note in a similar but stationary receiving system; or the receiving aerial may also be rotated. Alternatively the transmitting aerial may be stationary, and the receiver alone rotated. Specification 312,187 is referred to.

Filed: 1928-05-30
Abstract: 291,741. Svenska Aktiebolaget Bromsregulator. June 7, 1927, [Convention date]. Compensating for wear.-Relates to slack adjusting mechanism for brake rigging of the kind in which the spindle of the adjuster proper is rotated during the application stroke of the rigging by means of a friction clutch which slips when the stress in the rigging rises due to the application of the brakes and consists in arranging the spring by which the clutch is engaged to abut on the end of the adjuster spindle, the adjusting nut previously provided being dispensed with. As is in the known construction, a short shaft 2 is secured into the end 1 of the adjuster spindle proper to which it is secured by a pin 3, and a housing 9 rotatably mounted thereon carries a pawl 10 for engagement with a ratchet wheel 8 disposed between friction clutch members 5, 7 of which the member 5 is secured to the shaft 2, the two members being coupled by projections 6. The housing 9 is operatively connected to the brake rigging. The spring 13<a> by means of which the parts 5, 7, 8 are gripped together instead of abutting on an adjusting nut mounted on a screwed part of the shaft 2 abuts as shown upon the end of the spindle 1 thus ensuring in reassembling the device after repairs a constant tension in the spring.

Title: Improved apparatus for measuring the camber, castor angle and king-pin inclination of a vehicle wheel
IPC: G01B5/255
Filed: 1946-05-31
Abstract: 612,699. Gauging alignment of vehicle wheels. DUNLOP RUBBER CO., Ltd., and HARDMAN, J. H. Mav 31, 1946, No. 16522. [Class 106 (ii)] In a gauge for measuring camber, caster, and king-pin angles of a vehicle wheel, of the type comprising a bar 1, three distance pieces 8, 8, 9, extending therefrom terminating in contact surfaces, means for indicating when the longitudinal axis of the bar lies in a vertical plane at right angles to the plane containing the contact surfaces, and an arm 2 pivoted to the bar at 2a provided with index marks 4, 4a moving over scales 5, 6 fixed to the bar, means are provided for locating the pivoted arm 2, together with its indicating and associated scale means, with its pivot 2a either normal or parallel to the plane containing the contact surfaces. This locating means, which facilitates gauging king-pin inclination, comprises a bar 1 of square section fitting square holes in the sockets of the distance pieces 8, 9, and a pin 1a (not shown) on the bar adapted to engage either of two notches 10a in the socket 10 of distance pieces 8. The bar is lifted out of the socket 10 and re-inserted after being turned through a right angle, whereupon the scales and arm 2 will face outwardly away from the wheel. To measure the camber angle the gauge is arranged as shown, the legs 8, 9 contacting the rim 7 of the wheel and a level 12 on the bracket carrying the legs 8 is used to' ensure that the bar 1 is in a vertical plane at right angles to the wheel. The arm 2 is adjusted to a vertical position by observing a level 3 on that arm, and the camber angle is given by the index mark 4 on the lower scale 5. For caster angles the wheel is deflected through a specified angle and the gauge used as before, but the reading is taken on the upper scale 6. This process is repeated for a similar deflection in the opposite direction. The scale 6 is so devised that the difference between the two readings can be used to give the caster angle. As mentioned above, for measuring king-piii inclination the pivoted arm and scales are arranged to face outwardly, the top leg 9 also being suitably adjusted. In one method the nearside wheel is deflected to right lock through a specified angle, the gauge applied to the wheel with the bar 1 in a vertical plane at right angles to the plane of the wheel. The level 3 on the arm 2 is next centred, the reading on the scale 6 noted, and the gauge removed. This process is repeated on the left lock with the legs 8, 9 in exactly the same position on the wheel, and the difference in the readings on the scale 6 gives the king-pin inclination. In a second method, the index mark 4a is pre-set on the scale 6 and the level 3 centred by bodily rotation of the gauge. A skeleton template of rectangular form and provided with diagonal members can be used to ensure that the wheel is deflected accurately to the specified angle for gauging purposes.
