Filed: 1917-07-11
Abstract: 117,299. British United Shoe Machinery Co., (United Shoe Machinery Co.) July 11, 1917. Dreasting.-A stop or bunter to limit the relative approach of the knife and work in a machine for breasting heels already attached to shoes comprises two members 28, 30 carrying pads 44 of leather &c. adapted to engage the opposite marginal portions of the shank of the shoe near the heel breast. The members are pivoted at 32, 34 in a cylindrical block 24 fitted in a split clamp 12 at the upper end of a support 10, which is mounted on a pin 14 fixed in a toothed slide 4 vertically adjustable by means of a worm 8 in a T-shaped guide in the usual stop arm 23 of the machine. A spring-pressed pin 16 housed in the support 10 bears on a flattened portion of the pin 14 and normally holds the members 28, 30 symmetrical, but permits the pressure of the members on the work to be equalized by movement about the pin in case one member comes into firm engagement with the work before the other; directly both members bear firmly on the work the stop arm 23 is operated to arrest the cutting action of the breasting knife. The upper ends of the members 28, 30 are toothed to engage peripheral flanges 36 on a rotatable stud 40, which has a reduced portion 42 threaded into the block 24; by rotating the stud, the spread of the members 28, 30 is adjusted, and the angular positions of the work-engaging faces of the pads 44 in a vertical plane are, as a consequence, varied to correspond with the lateral inclinations of the shanks of different shoes, as indicated in dotted lines in Fig. 3. The pads 44 are adjusted towards and from the heel breast by rotating the block 24 in the split clamp 12, which, when tightened by its bolt 22, maintains the members 28, 30 securely in both their lateral and longitudinal adjustments.

Title: Radio connection in combination with telephone circuits
IPC: C04B28/02
Filed: 1935-04-01
Abstract: 454,564. Exchange systems. MASTINI, D., 251, Corso Vittorio Emanuele, Rome. April 1, 1935, No. 10097. [Class 40 (iv)] [See also Group XL] Telephone subscribers are provided with apparatus whereby they may communicate with any other subscriber through the exchange network with the aid of portable wireless apparatus when they are away from their substations. As shown, the removal of the instrument at the portable set shown on the left of the Figure switches on the transmitter Tm and the reception of the resulting signal by the circuit RF at the substation produces a voltage for biassing the speech amplifier BF and energizes a relay A which energizes a relay B so that the telephone set is disconnected and the line is bridged over a repeating contact and associated with the wireless apparatus. Impulses dialled at Z are repeated by A to the exchange at which the call is established in known manner. A call from the exchange energizes a relay E which switches on the transmitter Tf and makes a circuit for a self interrupting relay V to cause buzzer-modulated carrier wave to be sent out. E locks up and energizes a thermal relay T.C., which in due course shunts the locking circuit. When the portable station answers the call, the consequent switching on of the transmitter Tm causes the actuation at the substation of relays A, B which complete the circuits described above.

Title: Improvements in Processes of Producing Dinitrophenol.
Inventor: BREWSTER THEODORE JEFFERSON
IPC: C07C205/23
Filed: 1918-06-26
Abstract: 131,403. Brewster, T. J. Nov. 20, 1917, [Convention date]. Dinitrophenol is prepared by treating benzene at 50-60‹ C. with nitric acid of 45-55 per cent. strength in the presence of a mercury compound, further nitration to picric acid being avoided by continuously or intermittently withdrawing the liquid reaction mixture, cooling it to crystallize out the dinitrophenol, filtering off the crystals, and returning the filtrate to the reaction chamber. Silver nitrate may be used in conjunction with the mercury. Using the apparatus shown, the nitrator 1 is charged with nitric acid of 50 per cent. strength containing dissolved mercury, the charge is brought to 50‹ C. and a proportion of benzene is run in from tank 31. The hot acid liquor is pumped through a cooler 12, the crystallized dinitrophenol is separated in the filter 15, and the filtered liquor passes back to the nitrator by pipe 17. A portion of the acid is diverted by pipe 18 through tank 19 to a concentrator 20, and the concentrated acid then passes back to the nitrator by pipe 21. The benzene vapours and nitrogen oxides evolved in the nitration pass to a cooler 6, where the benzene condenses and flows back to vessel 1, while the nitrogen oxides pass on to a tower 9 where they are reoxidized by air to nitric acid. Fumes from the concentrator 20 similarly pass to a cooler 24 where weak acid condenses, while uncondensed fumes pass on by pipe 26 to the tower 9. Fresh nitric acid and benzene are supplied as required from tanks 27, 30. Any dinitrophenol collecting in the cooler 12 may be removed by circulating benzene from tank 31 therethrough at intervals, such benzene containing dissolved dinitrophenol being then sent into the nitrator.

Title: A screen printing machine for printing lengths of textile material, films or the like
IPC: B41F15/42
Filed: 1952-04-30
Abstract: 718,459. Stencilling-machines. LAUPMAN, R. R. April 30, 1952 [May 2, 1951], No. 10882/52. Class 100 (2). In a machine for printing through a stencil screen on to films or webs of textile material, the squeegee is lifted during each printing cycle into an inoperative position in which it performs an even number, e.g. two, inoperative strokes and is then lowered into operative position and performs a number of operative strokes fewer than the number of inoperative strokes, e.g. one. The machine comprises a bed 1 and driving means 2 having a chain driving spindles 4, 10. Spindle 4 carries an arm 5 connected to a chain 7 passed over a sprocket 8 and attached to a tension spring 9. The sprocket 8 is connected through a one-way coupling to a roller 27 driving a belt 26 passing over the surface of the bed. The web of material 28 is lightly stuck to the belt, e.g. by means of a potato flour glue, and advanced in steps over the bed, being stripped off the belt by a blade 30 at the other end. The spindle 4 also carries a cam 46 acting on a follower roller 19 attached to one end of a lever 17 pivoted to the bed at 20 and connected with a similar lever 16 pivoted at 21. Rollers 25 at the outer ends of the two levers support an oscillating frame 14 driven from spindle 10 by a crank arm 11 and connecting-rod 13. The screen frames 37, Fig. 2, e.g. three for multi-colour printing, are supported on side rails 38, attached by adjustable clamps 39 to end members 40 having brackets 41 carrying downwardly-projecting rods 15, 23. The rods are engaged by the ends of levers 16, 17 towards the end of their upward movement, to lift the screens and allow the web to move forward. The squeegees are carried on cross-members 33, Fig. 2, secured by clamps 32 to the frame 14. The ratio of the speeds of the spindles 4, 10 is, in this example, two: three so that the squeegee carriage makes six strokes to two forwarding steps of the web, i.e. three strokes during each printing cycle. The action of the squeegee is shown in Fig. 4. Starting from an end position behindthe swept up printing paste 45 the squeegee passes across the screen making a printing stroke-a. It is then lifted into inoperative position and makes two idle strokes b, c, being lowered again on the left-hand side of the paste 45 swept up by stroke a. During the idle strokes b, c the web has advanced by one step and the next printing stroke d is made on a fresh part of the web. The remaining two strokes of this cycle are idle and return the squeegee to the initial position shown in full lines. The squeegees are vertically adjustable.
