Title: A control valve for compressed gases
IPC: G05D16/10
Filed: 1953-01-21
Abstract: 742,117. Fluid-pressure servomotor-control systems. HAMPEJS, K. Jan. 21, 1953 [Feb. 23, 1952], No. 1758/53. Class 135. A compressor by-pass unloading valve for maintaining the gas pressure in apparatus supplied thereby at a predetermined value comprises a casing 23 having an inlet 1 from the compressor, an outlet 2 controlled by a non-return valve 3 to a gas storage container and an atmospheric outlet 25 controlled by a pilot valve actuated, by-pass unloading valve 21. The valve 21 has a bore 7 in constant communication with the container through passages 4, 6 and a hollow piston 10 slidable with clearance in a chamber 16 in the casing 23. The piston 10 slidably mounts with clearance a pilot valve 9 engageable with oppositely facing seats 14, 26 and loaded by a spring 11 adjustable by the casing closure cap 24 which also limits the upward movement of the piston 10 and has a vent 20 to the atmosphere. When the pressure within the container is below that determined by the spring 11, the pilot valve 9 is seated on its lower seat 26, the chamber 16 then being open to atmosphere through the vent 20 and the valve 21 closed. On the pressure within the container rising above that determined by the spring 11, the pilot valve 9 is raised to its upper seat 14; the chamber 16 then communicates with the container whence the piston 10 is raised and the valve 21 opened.

Title: Improvements in or relating to roll film cameras
IPC: G03B19/04
Filed: 1943-02-03
Abstract: 563,305. Roll-film cameras. KODAK, Ltd., and NAGEL, H. Feb. 3, 1943, No. 1795. [Class 98 (i)] The film-feeding mechanism of a camera is locked after a pre-set number of exposures by a device controlled by means comprising a notched disc connected to a sleeve which is manually adjustable together with a pointer in a counter-clockwise direction to pre-set the number of exposures, and is rotated in a clockwise direction through a friction drive by a ratchet wheel driven by a pawl at each operation of the film-feeding member. During manual pre-setting of the device, the ratchet wheel is held against movement through the friction drive by a pawl. When the pre-set number of exposures has been made, the notched disc reaches a position in which it allows the latching means to operate. In the camera shown, which is intended for photographing X- ray screen images, the film is fed between exposures by a down-stroke of a lever 9 through mechanism described in the abridgment of Specification 563,304. At each return stroke of the lever 9, a pawl 62, which is pivotally carried on an eccentrically-mounted bearing rocked by an arm 66 connected by a link 67 to the lever, moves a ratchet disc 56 through one tooth, thereby rotating a dial plate 47 mounted on the same sleeve 50 as the ratchet relatively to a fixed index 71 to indicate the number of exposures. In order to predetermine the number of exposures to be made, a knob 49 which drives the dial 47 and disc 56 through a friction coupling is rotated clockwise until the zero mark on the dial is opposite the index 71. The knob is then rotated anti-clockwise until a pointer 48 secured to it indicates on the dial the desired number of exposures, the dial and disc 56 being held against rotation in this direction by the pawl 62, and the friction coupling allowing the knob to be turned. This setting adjusts a notched disc 54 so that after the desired number of exposures have been made the notch reaches a position in which a pin 72 on a spring-urged latch arm 73 falls into it, so bringing a notch 76 in the arm into the path of a projection 77 on the film-feeding lever 9 and preventing further actuation. The hatch may be released manually by the means described in Specification 563,304. A modification is referred to in which the dial 47 is dispensed with, and the pointer 48 is turned to indicate on a fixed scale the number of exposures to be made. Specifications 549,194 and 563,308 are also referred to.

Title: A system of distribution for pneumatic hammers and other tools driven by compressed air
IPC: B25D9/18
Filed: 1921-01-13
Abstract: 169,656. Skerrett, H. N., (Soc. Anon. des Etablissements Franþois). Jan. 13, 1921. Percussive hand tools.-The fluid supply from the inlet 10, Fig. 1, to the cylinder ends is controlled by a reciprocated valve 1, and the cylinder exhaust through ports 14, 16 by the main piston. The valve is moved by the formation of a differential pressure on the two faces 8, 9 of the groove 7, or of a collar on the periphery of the valve. When the cylinder exhaust is opened, the increase of pressure in the inlet 10 is transferred first to the face 9 to move the valve to the right, since the face 9 is nearer the port 11. In the modification shown in Fig. 3, nozzles 17, 18 with open rectangular ends facing one another connect the inlet 10 and groove 7. The rush of fluid in the direction x<1>, x<2>, x<3>, for example, when one of the exhaust ports is opened, causes an increase and decrease of pressure on faces 9, 8 respectively, and thus a pressure to the right.

Title: Improvements in or relating to roasting process
IPC: C25C3/06
Filed: 1952-01-30
Abstract: Bath values consisting of cryolite, fluorspar and alumina which have become contaminated with carbon during the electrolytic production of aluminium and which also contain sodium hydroxide, are recovered by heating the values, which may be cell skimmings, spent carbon cathodes or linings, in particulate form to a temperature below the fusion point of the contained sodium hydroxide (600 DEG F.) with a free oxygen containing gas for a time sufficient to convert all the sodium hydroxide to sodium carbonate and subsequently heating to a temperature sufficient to cause oxidation and removal of all the free and combined carbon, e.g. 1150 DEG F.  Aluminium nitride and carbide in the case of linings and calcium carbide in the case of skimmings are decomposed by adding water prior to the roasting operation or during the operation. Preferably the roasting is effected in a multiple hearth furnace, for example containing seven hearths, the centre five of which are electrically heated, the top hearth being a preheater and the bottom hearth, containing an air and water vapour inlet, serving to cool the material.  Air cooled rabble arms transfer the materials from hearth to hearth.  The material is heated for 1/2 hour in the top hearth at 500 DEG F. and the temperature increased in successive hearths until 1150 DEG F. is reached between the fifth and sixth hearth.  As the material is rabbled along the bottom hearth it is cooled by the incoming air to 225 DEG F.  The cooled calcine containing little aluminium nitride or carbide, sodium carbonate or hydroxide and not more than 2 per cent. carbon, may be returned to the electrolytic cell, aluminium fluoride being added to adjust for the excess alkali, or aluminium fluoride may be ground into the calcine in a ratio of 1 to 4.
