Title: Improvements in or relating to Heel-attaching Machines for use in the Manufacture of Boots or Shoes.
IPC: A43D79/00
Filed: 1916-08-05
Abstract: 108,212. British United Shoe Machinery Co., (United Shoe Machinery Co.). Aug. 5, 1916. Heels, machines for.-Heel-attaching machines of the type described in Specifications 3314/91, 5084/03, and 2393/15 are provided with automatic means for moving a heel and top lift carrier about one of the side rods as a pivot to transfer the blanks to attaching position. The carrier is journaled on the right hand side rod 20 and comprises a plate 28, Figs. 2 and 3, having four radial arms to receive alternate heel and top lift blanks, which are positioned and held by adjustable. fork-ended back gauges 44 and spring- pressed slidable breast gauges 46. The carrier plate 28 is cut away at its centre and carries four downwardly-extending arms 30 which merge into an annular flange 32 resting on a ring 34 loosely journaled on the rod 20 and supported on the upper bearing 200 of the rod. The carrier plate is adapted to be rotated by a spring 50 connected to one of the arms 30 and to the ring 34, which is formed with ratchet. teeth and is rotated intermittently by a pawl 52 carried by a bracket 54. This bracket is supported by engagement with a flange 60 projecting from a nut secured to the machine frame and is bolted to a sleeve 56, which is formed with an inclined slot 64 to receive a pin 62 projecting from the rod 20. During the downward movement of the side rod, the pawl 52 turns the ring 34 through substantially 90 degrees and places the spring 50 under tension, the ring being prevented from backward movement by a second pawl 66. The operator slides the jack into operative position in the usual way and then trips a hand-lever 42, which releases a spring locking-dog 38 from a notch 36 in the blank-holder then in operative position and allows the spring 50 to rotate the carrier plate to move the next holder over the jack. The machine is then started, and in the upward movement of the side rod 20 the sleeve 56 is oscillated back again and carries the pawl 52 to a position adjacent to the next tooth on the ring 34. It is sometimes necessary for the machine to make two driving or two spanking strokes, and to permit this without excessive tensioning of the spring 50 a spring pressed shield 70, Fig. 4, is provided to prevent the pawl 52 from engaging the ring 34 unless the hand-lever 42 has been moved to allow the carrier plate to rotate. In the normal operation of the machine, however, the arms 30 in turn engage an upstanding tail of the shield and move the shield into an inoperative position.

Title: Dental or like chair having a seat which can be raised and lowered
IPC: A61G15/02
Filed: 1953-04-22
Abstract: 720,925. Dental chairs. HARTMANN, G., [trading as EMDA, FABRIK ELEKTROMEDIZINISCHER UND DENTALER APPARATE, G. HARTMANN]. April 22, 1953 [May 2, 1952], No. 11106/53. Class 52 (2). In a dental' &c. chair having an actuating lever for raising and lowering the seat by means of an oil-pressure pump driven by an electric motor the actuating lever is arranged so that it has to be raised from the neutral position to raise the seat and to be depressed from that position to allow the oil pressure to discharge and so lower the seat. As shown, the actuating lever is a pedal 15 connected by arms 16 to a sleeve 17 oscillatably mounted on a spindle 18. The sleeve 17 has an offset portion at one end which is engageable with a lug 231 offset from a rocker arm 20 which is biased by a spring 21 to bear with its projection 35 against a fixed stop 22, Figs. 3, 3a, which show the lever and rocker arm in neutral position. To raise the seat the actuating lever 15, 16 is raised until its projection 23 bears against the fixed stop 22, the rocker arm 20 not moving since the lug 23<SP>1</SP> is not engaged by the offset portion of the sleeve 17. The mercury switch 5 mounted on the pivot 30 of a rocker 31 is actuated by means of a finger 32 engaging the plate 33 so starting the electric motor. Releasing the pedal lever 15, 16 allows it to return to neutral position switching off the mercury switch 5 but preventing discharge of the oil pressure. Downward movement of the pedal switch 15, 16 causes the rocker arm 20 to be rocked downwardly by the engagement of the offset portions of the sleeve 17 and the rocker arm. A pin 25 on the rocker arm 20 moves the bell-crank lever 26, 27 anticlockwise so depressing the valve 7 and releasing the oil pressure.

Title: Improvements in or relating to extraction of uranium compounds
IPC: C22B60/02
Filed: 1948-04-22
Abstract: Uranyl nitrate is separated from aqueous solutions thereof by extraction with an organic compound containing a cyclic ether group and especially such a compound having a 5- or 6-membered ring. Preferred compounds have a furane of pyran nucleus, for example tetrahydrofurane, tetrahydropyran and dihydropyran.  The organic compounds preferably contain only carbon and hydrogen besides the cyclic ether group.  According to examples: (1) aqueous uranyl nitrate solution containing ammonium nitrate and nitric acid was extracted with an equal volume of tetrahydrosylvane, the partition coefficient being 38.  The uranium compound is recoverable by evaporation of the organic compound which may be condensed and used for further extractions; (5) Monazite sand was heated with concentrated sulphuric acid at 200 DEG  C., the mixture cooled, centrifuged and the supernatant liquid separated.  The residual sulphates were washed with concentrated sulphuric acid and the liquid removed.  The solids were dissolved in water and caustic soda added to a pH of 8 whereupon the precipitated solids were filtered, washed and dissolved in nitric acid to yield a solution having a pH of 1.5. This nitric acid solution was extracted with 2-methyltetrahydrofurane and the organic solvent extract was washed with water to bring the uranium into an aqueous solution which aqueous solution was evaporated to dryness and calcined to U3O8.  Further examples compare the extractions with tetrahydropyran, dihydropyran and the conventional extraction solvent, diethyl ether.  Further cyclic ethers which are referred to are 2 - methyl - tetrahydrofurane (tetrahydrosylvane), 1 - methyl - 3 - (21 - tetrahydrofuryl) propyl ether, tetrahydropyran, dihydropyran, di - (21 - tetrahydrofuryl) - 1 : 5 - pentane, 2 - n - butyltetrahydrofurane, 2 - n - butyl furane.

Title: Improvements in vacuum brakes for vehicles
IPC: B60T13/46
Filed: 1925-05-01
Abstract: 247,043. Soc. Anon. Servo-Frein Dewandre. Feb. 10, 1925, [Convention date]. Fluid-pressure; hand and foot actuation.-In a vehicle driven by an internal-combustion engine and utilizing the engine suction to apply the brakes, the air admitted to the brake cylinder to effect release of the brakes is taken from the crank case of the engine, so that the oil vapours it carries serve to lubricate the distributor and the brake cylinder. The distributor comprises two slide valves 61, 62, the former being connected to the brake pedal 13 and being provided with ports 67 adapted to register with ports 68 or 69 in the slide valve 62, which is connected to an arm 66 of the brake rigging. A pipe 64<1> connects the port 69 to the induction pipe 1 of the engine, and a second pipe 74 connects the port 68 to the crank case 75, whilst a pipe 2 leads to the brake cylinder 3. The slide valves are shown in neutral position, but when the pedal is depressed to connect the ports 67, 69, the brake piston 4 is moved inwardly to actuate the brake rigging, the movement of which, however, moves the slide valve 62 to the left to return the valves to neutral position unless the pedal is further depressed. The brakes may therefore be applied gradually by successively throwing the ports 67, 69 into register and permitting the movement of the rigging to disconnect them. By depressing the pedal sufficiently to take up the lost-motion between it and a stop on the arm 66, the effort exerted on the pedal may supplement the braking effort exerted by the brake-cylinder.
