Title: Improvements in radio receivers
IPC: H04B1/16
Filed: 1923-07-02
Abstract: 222,562. Ashbridge, N. July 2, 1923. Thermionic amplifiers and detectors.-A valve set is arranged so that a stage of high-frequency amplification can be brought into circuit after reception has first been secured on a single detector valve without losing the signal during the change-over. The first valve A is a detector, and comprises in its plate circuit the reaction coil L<2> and the primary P of a low-frequency transformer, which is also common to the plate circuit of the third valve C. The intermediate valve B is a high-frequency amplifier with a tuned anode circuit L<3>, C<3>, the grid being connected to 'the high-potential end of the aerial inductance L<1> as shown. The plate is connected through a condenser C<4> to the grid of the second detector valve C. Rough tuning is carried out with the valve A alone in circuit. When the signal has been located the valves B and C are lit, and the tuning process is completed on the condenser C<3>. With this arrangement a high ratio of inductance to capacity may be used in the tuned anode circuit giving increased selectivity without an undue tendency to self-oscillation. Reversed reaction mav be utilized between the coils L<2> and L<1> in order further to stabilize the set.
Patent GB-362439-A (GB)
Title: Improvements relating to processes for the heat treatment of rails or other massive steel bodies
IPC: C21D9/04
Filed: 1930-06-04
Abstract: A rail or other massive steel body which has already been rapidly cooled below the critical range so that substantial temperature differences exist therein, is immersed in a highly heat-conductive medium, such as a molten lead bath, at a temperature above the "blue heat" zone (ordinarily between 200 DEG  and 300 DEG  C.) and below the critical range to reduce the temperature differences quickly.  A good proportion of the interior of the rail, particularly the head, will still be above the blue heat zone so that the reduction of the temperature differences diminishes the chances of permanent defects from strains produced by the differences.  The rail may be taken from the bath and then tempered in a furnace at 1000 DEG  F. or the tempering may be effected in the lead bath by prolonging the immersion therein.  An example of the range of composition of steel for the rail is given.  Reference has been directed by the Comptroller to Specifications 1842/04 and 12098/04, [both in Class 72, Iron &c.].

Filed: 1926-07-10
Abstract: 268,608. White, M. L. July 10, 1926. Inking-apparatus.-An inking-roller is rotatably mounted on a normally stationary shaft which is adapted to be turned to enable the roller to be removed from its supports in the machine. The shaft turns about an axis eccentric to that of the roller, so that when the roller is in position for removal. it is also in inoperative position relatively to the inking and forme cylinders. The roller 13, Fig. 2, consist of a tube 14 having a composition, rubber, or like covering 15, and is supported freely on its shaft 16 by antifriction bearings 17 secured in position against shoulders on the tube and shaft by a collar 22 locked in position by a set-screw. The outer ends of the shaft are formed with flattened surfaces 33 and with handles 45. Secured in each of the frames 12 of the machine, and in line with the contact lines of the roller 13 with the inking-cylinder 11 and forme cylinder 10, Fig. 4, are bolts 26, 27 having squared portions, on which are mounted, outside the frame 12, brackets 25. Screws 31, passing freely through the brackets, screw into the squared portions of the bolts and serve for adjusting the brackets to compensate for wear. or shrinkage of the roller surface 15. Either screw 31 is independently adjustable without disturbing the adjustment of the other. The brackets are bored at 47, Fig. 6, and an opening 48 is made in the bearings for the passage of the roller shaft 16, extensions 36 on the brackets serving for temporarily supporting the shaft. Bushings 34, Fig. 7, slotted for the reception of the shaft 16 are rotatably mounted in the borings 47 of the bearings 25, and one of them is provided with a handle 38 outside the bearing, a spring-pressed pivoted arm 39 being carried by the handle and having a pin thereon adapted to engage in openings 42, 43 in the bearing for holding the bushing in open or closed position. When the roller shaft is in the bushings, movement of the handle 38 rotates the bushing on which it is mounted, the other bushing being rotated by means of the flattened portions 33 of the shaft. The axis of the shaft 16 is disposed eccentrically relative to the axis of rotation 50 of the bushings so that rotation of the bushings moves the roller into or out of contact with the cylinders 10, 11. The bushings 34 are provided with flanges contacting with the outside of the bearings 25, and with shoulders 46 engaging the inside of the bearings to prevent longitudinal movement, the shoulders 46 being of a length slightly less than the width of the openings 48 to permit withdrawal of the bushings.
