Title: Improvements in and relating to filters or strainers
Inventor: SHOOSMITH GUY TAITE
IPC: B01D35/00
Filed: 1956-10-02
Abstract: 816,407. Filters. PLENTY & SON Ltd. Sept. 27, 1957 [Oct. 2, 1956], No. 30060/56. Class 46. In a filter which includes a hollow body with inlet and outlet passages which are horizontal in the normal position, a perforated filtering basket, and an access hole above the basket normally closed by a removable cover, the latter is in the form of a solid piece of metal domed downwards towards the basket, the peripheral portion of the lower surface of the cover being no higher than the upper level of the inlet and outlet passages, and the central portion being lower, to prevent air locks. In the embodiment shown the part-spherical surface 42 on the underside of the cover 22 engages a spring handle 40 on a perforated basket 16 to press a flange 18 on the latter against a flange 20 in the body 10. Lugs (not shown) on the cover 22 may, by appropriate positioning of the cover, be located above lugs (not shown) on the outside of the body 10 so that a lever (e.g. the pin 34 otherwise used to removably secure one end of a strongback 28 to the body 10) may be inserted between two vertically adjacent lugs to prise off the cover 22. The other end of the strong-back 28 is hinged by an irremovable pin 32.

Title: Improvements in or relating to a method for the production of envelopes
IPC: B31B150/00
Filed: 1955-10-21
Abstract: 780,554. Making envelopes. WINKLER, R., and DUNNEBIER, K. Oct. 21, 1955 [April 7,1955], No. 30099/55. Class 94(2). In a method of making an envelope from a continuous web 12, rhombic shaped blanks 14 are cut from the web, parts 5 removed to produce rides 2, 3, bottom 1 and closure flaps 4, the sides being of a length substantially less than one half the width of the finished envelope, and the bottom flap 1 cut at 6 so that the cut edge extends between the upper edges of the side flaps. One or both points of the side flaps may be cut off. The method may be carried out on an adapted machine normally used for producing envelopes of the kind in which the side flaps overlap and the bottom flap is not cut, the web 12 being run through at an angle to the line X Y of movement of the envelope blanks, less than that normally used. The position of the web when making envelopes with overlapping side flaps is shown at A.

As examples of such complexes are specified a solution in isopropanol of stearate chromic chloride, and a solution in isopropanolwater of methacrylate chromic chloride.  The treatment may be effected by homogenizing the complex with a water slurry of the silica, or by tumbling the dry silica in an inert gas such as nitrogen, which is saturated with the complex, or by adding a small amount of silica to a much larger amount of the complex and blending the resulting mixture with further silica, or by spraying the liquid complex, alone or in a solvent, on to the silica.  The silica may be prepared by reacting an alkali metal silicate or an alkaline earth metal silicate with an acid as described in Specifications 745,822 and 756,857. Specification 743,930, U.S.A.

Title: Foundry molding machines
IPC: B22C17/10
Filed: 1931-11-06
Abstract: 389,177. Moulding-machines. NICHOLLS, W. H., Roslyn, New York, U.S.A.-(Assignee of Ziebarth, A. D. ; 115-91, Metropolitan Avenue, Kew Gardens, Queens, New York, U.S.A.) Nov. 6, 1931, No, 30782. Convention date, Nov. 19, 1930. [Class 83 (i).] A roll-over moulding-machine has a cylinder 9 carried by a trunnion 11 and itself carrying a flask support, a plunger 44 being arranged in the cylinder and carrying a clamping head 45 and pistons being arranged in the plunger so that it can be moved by admitting pressure fluid. The trunnion is carried in horizontal bearings 14 of a stand 1, and can be inverted by chain gearing 80, crank 88, and a piston 85, in a pivoted cylinder 82, operated by pressure fluid controlled by a valve 89 which is operated by hand through linkwork 121, 116, 119. Fluid is admitted to each cylinder end by a non-return valve 109 and is exhausted by a small port to cushion the roll-over movement. The head 45 is adjustable and can be swung aside on pivots 72. The plunger has closures 46, 51, 48, of which 51, 48 have sliding engagement with a pipe 52 connected to the bottom 10 of the cylinder 9 and carrying fixed pistons 56, 59. Pressure fluid can be admitted by pipes 129, 19, 132, hand-operated valve 125, Fig. 5, pipes 126, 52, and openings 64, 65, to the spaces 61, 62 thus moving the plunger 44 and head 45 down to press the sand in a mould resting on a table 23. In another position the valve 125 admits fluid by a telescopic pipe 127 to the space 60 thus withdrawing the head 45 for the introduction of a flask &c. or in the inverted position for drawing the pattern, the first movement being limited by a hook 67, Fig. 2, and loop 69. Pressure fluid can be admitted by a pipe 133, Fig. 5, a valve 30, controlled by a handle 32 which also withdraws a lock-bolt 35, Fig. 2, passages 25, 27 in a cylinder 20 and plunger 22 respectively, to a space below the plunger which is raised thereby until it closes the passages 25 and opens others 29 to exhaust. This causes the plunger, and table 23 carried thereby, to jolt the mould until the handle 32 is released and the bolt 35 returned by a spring 34 to lock the plunger 22. Rotation and undue rise of the table 23 is prevented by a bolt 38 and lubricant 21 is supplied to the plunger 22, each time the frame 2 is inverted, by a lip 42 and passage 43 and to the plunger 44 by a pipe 43<1>. The spaces A, B are vented by passages 136, 137 and rotation of the plunger 44 is prevented by a set-screw 139, Fig. 5, and slot 140.

Title: Process of removing phosphorus, silicon and vanadium from pig iron, cast iron and steel
IPC: C22B34/22
Filed: 1952-12-05
Abstract: A process of recovering vanadium from pigiron, cast iron and steel and simultaneously removing, if desired, phosphorus and/or silicon, consists in oxidizing these elements by running the molten metal on to iron sulphate and/or alkali metal sulphate and/or calcium sulphate in admixture with an alkali metal, preferably sodium, carbonate and/or oxide and/or silicate, the proportion of sulphate to the alkali metal carbonate and/or oxide and/or silicate being between 10 : 1 and 1 : 1, preferably 3 : 1. The reaction may take place in a ladle or mixer and the phosphorus may be oxidized more quickly than the silicon by using a silicate in combination with the sulphate.

Abstract: 176,061. Caballero, A. Nov. 2, 1920. Codes.-An appliance is provided for transforming code numbers in artificial words of fewer letters than there are digits in the numbers, and vice versa, for example numbers of five or six digits into four-letter words containing two vowels and two consonants. The consonants are determined by the thousands and hundreds of the number, the vowels by the tens and units, and the relative order of the consonants and vowels- CVCV, CVVC, VCCV, or VCVC-by the subdivision in which the first vowel is found. Two four-letter words may be combined with a check syllable, determined by the tens and units of the sum of the digits of the two numbers in pairs, to form a ten-letter word. Six-digit numbers are reduced to five digits by subtracting a predetermined constant from the thousands. The appliance comprises a series of five concentric rings A - - E mounted for independent rotation and subdivided into four quadrants by arms 5 - - 8. The first ring A may be fixed and carry the arms 5 - - 8, as shown, or may be independent of the arms to obtain a greater number of changes of key. The rings are subdivided radially and contain in each subdivision a single letter or a number of one or two digits. Rings A, C, E bear numbers to be used respectively for the hundreds, thousands, and tens and units. Rings B and D bear respectively consonants and vowels, the latter repeated in the four quadrants. When the numeral for a particularly denomination is not found on the appropriate ring, the next smaller numeral found is taken, and the difference is added on to the numeral of the next lower denomination, the units remaining after selection from ring E being found on ring A. The quadrants are distinguished by signs indicating the relative order of the vowels and consonants.
