Title: Improvements in pressure and vacuum alarms
Filed: 1921-01-17
Abstract: 178,545. Stokoe, C. L. Jan. 17, 1921. Alarms, high and low pressure.-In fluid-pres-- sure-actuated alarm apparatus applicable to steam generators and of the kind in which a flexible diaphragm operates an electric switch at any predetermined rise or fall of pressure from normal within a chamber of which it forms one wall, one switch member is mounted on the diaphragm spindle and is protected from injury due to excessive pressure by means of buffer springs. Means are also described for rendering the spindle fluid-tight where it passes through the casing, so that pressure may be applied on both sides of the diaphragm. The fluid-tight diaphragm g carries a pressure-supporting disc p and a spindle i and is forced downwards by a spring w. The spindle passes through the casing and carries an insulating piece e to which are fixed pillars d carrying an electric contact a. Mounted on pillars fixed to the casing is an insulating slab z which carries pillars supporting insulated metallic bridge-pieces b, c situated above and below the contact a respectively. When the diaphragm rises or falls due to variation of pressure thereon, the contacts b or c will be closed and alarms operated. Buffer springs support each of the contact pieces on the pillars so that excessive pressure cannot damage the contacts. The spindle is made fluid-tight with the casing in the " up " and " down " positions by collars n fixed to it, or permanently fluid-tight by a bellows connection as shown in Fig. 2<A>. The spring w may be fitted inside the casing, or a deadweight dd may be substituted for it, and the buffer spring for the movable contact may be carried by the spindle.

Title: Improvements in or relating to processes and apparatus for the recovery of fats, oils or oleaginous substances from fatcontaining materials
IPC: C11B1/02
Filed: 1926-01-29
Abstract: 269,985. Powling, W. T. Jan. 29, 1926. Fats and fatty oils, extracting.-In apparatus comprising a degreaser in which the raw material is heated to melt out the fat, and an extractor to which the heated material is transferred to separate the melted fat from the solid residue, no gases or vapours are allowed to escape to the atmosphere until the operation is completed. In the apparatus shown, bones or other materials are fed through a hopper 14 into a steam-jacketed degreaser 10 of the kind described in Specification 8397/12, and are discharged through a valved outlet 16 to a steam-jacketed extractor 22 of the kind described in Specification 128,397. The melted fat passes through the grid 24 to the hinged lower chamber 26, and thence through a valve 30, a flexible pipe 32, a pipe 31, and a perforated coil 35 to a closed steam-jacketed melting tank 33 having a valved outlet 46 to a cooler 44 with a valved outlet 48 to barrels or other storage receptacles. Gases and vapours produced in the process are withdrawn by a vacuum pump 40, those in the degreaser 10 passing through a pipe 27, a valve 28, the separator 22 in which they assist in the separation of the fat, and through the settler 33 to a deodorizer 41 containing carbolic acid, a jet condenser 42, the jacket 43 of the cooler 44, and a drain, furnace, or chimney. Benzine or other solvent may be passed into the degreaser through a valve 51 or into the extractor 22. The extractor 22 is discharged by opening a valve 60 to break the vacuum, and swinging the chamber 26 on its hinges. The vacuum in the degreaser 10 may be broken by opening a valve 61. Pressure above atmospheric may be created in the degreaser 10, e.g. for assisting in transferring the material to the extractor 22. by closing valves 21, 28, 61 and 51, and holding down the cover 15 In a modification the vacuum pump delivers the hot vapours through a coil in the hopper 15 whereby the raw material is preheated, the coil discharging into the deodorizer 41. In both forms of apparatus the deodorizer 41 may be omitted, or the pump 40 may discharge directly into a drain &c. Specifications 25683/04 and 162,699 also are referred to.

Title: Improvements in indexing mechanism for a machine table
IPC: B23Q16/06
Filed: 1945-02-02
Abstract: 588,179. Drilling-machines ; turrets. BURGESS, A. F. (Barnes Drill Co.). Feb. 2, 1945, No. 2681. [Class 83 (iii)] In a mechanism for indexing, a reversible electric-motor drives a yieldingly mounted worm-gear in conjunction with a series of tripoperated switches to turn the turret to its indexed position, reverse and stop the motor. The rotatable table of a turret 10 is provided with worm-wheel teeth 26 meshing with a worm 46 splined and slidably mounted on a shaft 43, the worm body being extended to accommodate a yoke 61 integral with a notched shaft 60. A spring 50 urges the worm towards a collar 49 fixed to the shaft 43, the shaft being driven through bevel-gearing from a reversible electric-motor M, mounted on the stationary frame 32 of the turret. Inserts 24 are secured to the turret ring at the required indexing positions, each insert having a projection 27 with an inclined face 29 and a straight face 28. The inclined face works against a mating face on a turret locking-member 35 slidably mounted in the turret frame 32 and urged into contact with the face 29 by a spring 37. A stopmember 25 is also slidably mounted immediately above the locking-member 35 and is similarly spring-loaded to cause a projection 30 to engage the straight faces 28 of the inserts 24, the projection 30 being shaped to permit the inserts 24 to force it out of interference as the turret rotates in a clockwise direction. The locking-member 35 is provided with a roller 64 which, in conjunction with the notched shaft 60, moves the member 35 away from the path of the inserts 24, as the shaft moves laterally. The roller 64 also operates a limitswitch LS-2. The internal periphery of the turret is provided with a trip 57 at each indexing position to operate two limit switches LS-1 and LS-1a. In circuit with the motor is a push-button starter for energizing a starting- switch circuit, after which the limit-switches open this circuit and close a reversing-circuit until the limit-switch LS-2 cuts in to stop the motor at the finish of the indexing operation. On closing the starting circuit, the worm is rotated and moves axially up to collar 49 after which the worm drives the turret, the shaft 60 having moved with the worm to displace the locking-member 35. With an insert 24 slightly past its true indexing position the limitswitches reverse the motor thereby reversing the turret against the stop-member 25, after which the worm moves back past its original position to compress the spring 50 to a predetermined limit, when the switch LS-2 operates to stop the motor, the locking-member 35 having been returned to its inner position, and wedging the projection 27 against the stopmember 25, thereby securing the turret in its true indexed position.

Title: Improvements in or relating to the hardening of metals and alloys
IPC: C23C8/66
Filed: 1933-01-27
Abstract: Articles of metals and alloys are hardened by coating them with a layer comprising carbon containing bodies which are activated at high temperatures, together with finely divided catalytic metals, alkali or alkaline earth compounds of organic acids or carbonic acid and free alkali dissolved or suspended in water or other liquids, heating the coated articles to a temperature above the upper critical point and then quenching.  The materials are made up into a paste into which the articles are dipped or they may be painted with the paste. The coated article may be maintained at the temperature referred to above for a sufficient time to produce the desired thickness of the hardened layer before quenching.  Compounds of the catalytic metals may be used instead of the metals.  In an example, 100 parts of coke, 20 of nickel hydroxide, 15 of barium oxalate, 10 of strontium carbonate and 10 of potassium by dioxide are intimately mixed and made into a paste in 150 parts of water containing 5 per cent of gluten.  The articles are coated with the paste and heated to 950 DEG C.  Iron or steel articles may be case-hardened by the process or copper alloys, such as bronzes, hardened.

[Class 51 (ii)] The annular rotary hearth furnace described in the parent Specification is modified with the object of reducing the formation of dust. Air is supplied to the charge from an air box 7 through tuyere nozzles 5, and arrangements are provided by which each nozzle is shut off in turn as it passes the rabbling station. As shown, a wheel 16 is mounted on the air box opposite the rabbles and carries radial rods 17 which engage in turn with the tuyÞre nozzles as the rotation of the hearth turns the wheel. Charges, agitating.-Two or more rabble bars 12, 13 are used at each station instead of a single bar, and these are connected to the operating mechanism 14 so that they do not work in phase. A clutch is provided so that at least one of the bars can be disconnected from the drive. An even flow of air over the charge beneath the hood 26 is maintained by arranging the gas outlet therefrom diametrically opposite the working opening, or midway between them when two or more working openings are provided. To increase the speed of flow of gases over the hearth the hood may be made low and in this case the charge is fed from a hopper on to the upper surface of a low annular cooling- box. An upward stream of cooling-air may be induced by convection between the outer wall 26 of the hood and a surrounding ring 37.
