Title: Truss manufacturing system
IPC: G06F17/50
Filed: 1973-04-11
Abstract: 1432615 Data processing AUTOMATED BUILDING COMPONENTS Inc 11 April 1973 [12 April 1972] 17457/73 Heading G4A A method of producing an engineering drawing of a truss comprises the steps of electrically transmitting job data to a central computer from a remote user station, transmitting from the computer printed computed truss manufacturing data including drawing information and combining the printed data with a blank having a drawing of at least a portion of the truss to provide an engineering drawing. At the central computer there are a plurality of private user files and a plurality of truss data files held in a permanent storage area, at any one time the processing section of the computer holding one file, a primary file, this file then being able to receive data from a tele-typewriter at the user station to add to or modify it and to receive a program called for by the user. After use the primary file may be lost or if it has been modified the user may command that it be saved in permanent storage. The computer stores the principal truss fabrication program. The user file has two major sections, one for cost and efficiency factors and a lumber pricing file. A truss design input form (40<SP>1</SP>, Fig. 16b not shown) has rectangular boxes for the entry of identification information and design information which are filled in prior to transmitting the information to the computer. From this information a computer print-out is derived containing tables which represent the description of the truss design, the cost of the trusses and production information. If a drawing is requested the print-out of Fig. 18 (not shown) is provided which is designed to be used with the over-lay of Fig. 17 (not shown) which the user may hold at the remote station, to produce the information of Fig. 19. The over-lay has reference marks 64, 66 for alignment with asterisks 64, 66 of the computer print-out.

The phosphite esters may be prepared by a transesterification reaction between pentaerythritol and a trialkyl phosphite, e.g. triethyl phosphite or triisopropyl phosphite.  The resin-forming reaction mixture may also include an aliphatic polyhydric alcohol and there are specified ethylene glycol, propylene glycol, 1,4-butanediol, 1,6-hexanediol, 2-ethylhexane-1,3-diol, di-ethylene glycol, triethylene glycol, pentaethylene glycol, dipropylene glycol, tripropylene glycol, glycerol, 1,2,4-butanetriol, trimethylol ethane, trimethylol propane, pentaerythritol, sorbitol, mannitol, dulcitol and 2,4-dihydroxy-1,3-di(hydorxymethyl) pentane.  The reaction mixture usually contains an acidic catalyst such as sulphuric acid, hydrochloric acid, toluene sulphonic acid, benzene sulphonic acid, boron trifluoride, aluminium chloride, dialkyl sulphates, titanium tetrachloride, phenyl acid phosphate and octylphenyl acid phosphate. In a modification, acrolein is reacted with pentaerythritol in the presence of an acid catalyst to produce a liquid precondensate A-stage resin which is then reacted with the partial phosphite ester of pentaerythritol also in the presence of an acid catalyst. Examples 2-4 illustrate the two embodiments of the invention. Reference has been directed by the Comptroller to Specification 822,668.ALSO:A partial phosphite ester of pentaerythritol, utilized for chemically incorporating phosphorus into polymers (see Group IV(a)), is prepared by a transesterification reaction between pentaerythritol and a molar equivalent or less of a trialkyl phosphite:- <FORM:0908821/IV (b)/1> R being an alkyl group, e.g. ethyl or isopropyl.  Example 1 describes the preparation of the partial phosphite ester where R is ethyl.  Reference has been directed by the Comptroller to Specification 822,668.

Title: Process for the production of magnetic materials having high magnetic permeabilities
IPC: H01F1/00
Filed: 1962-05-08
Abstract: In the production of a magnetic material the carbon content of a conventionally produced steel is adjusted to 0.03-0.10% in the furnace, after which the carbon: oxygen ratio is adjusted to a predetermined value such as 3:4 by addition of a deoxidizer such as aluminium, silicon or ferrosilicon, or of carbon. The metal is then subjected to a vacuum degassing process, preferably of the batch type, as a result of which the carbon content is reduced to below 0.03%.  Alloying elements such as aluminium, silicon or molybdenum are then added and the metal cast.  As exemplified, an alloy containing 0.5% silicon was hot-rolled, heat-treated at 760  DEG C., cold-rolled, open-annealed above the recrystallization temperature, finally cold-rolled and annealed at 850  DEG C.  An alloy containing 3.1% silicon was hot rolled, annealed at 780  DEG C., cold-rolled, annealed at 900  DEG C., cold rolled, annealed at 800  DEG C. and finally annealed at 1150  DEG C.

Title: Improvements in flushing valves
IPC: E03D3/04
Filed: 1934-06-18
Abstract: 434,381. Flushing - valves. WILSON, E. C., 108, W. Fremont Place, Los Angeles, U.S.A. June 18, 1934, No. 17976. Convention date, Aug. 5, 1933. [Class 135] A flushing-valve of the kind wherein the flushing water is delivered directly from the supply line, is opened and closed by a piston controlled by an auxiliary valve which is opened to initiate the flushing action and is held open, irrespective of the duration of the initiating movement, until the piston has reached a predetermined position in its opening movement. The apparatus comprises a cylindrical body 10, having an inlet 12 and outlet 14, in which works a piston connected to a cylindrical valve 23, having grooves 28 formed on its inner surface, working over a fixed cylindrical sleeve 16. Rubber seatings 18, 25 respectively engaging the edges of the valve 23 and sleeve 16 seal the valve when closed. The piston is formed in two parts 21, 31 between which cup-leathers 33, 34 are clamped and has passages 37, 38, 48, the latter being normally closed by a valve 49. The passage 37 admits water to the hollow piston from which it flows through the passage 38 and a restricted passage 45 in a plate 40 to a space above the piston closed by a screw-cap 87 and pressure is built up to press down the piston. The plate 40 has a series of holes 45 of different sizes, any one of which can be placed opposite the passage 38 one of a series of corresponding notches 46 in the edge of the plate engaging a projection 43 to prevent movement. The plate 40 is clamped against a gasket 39 by a thumb-screw 41. The valve 49 has a stem 57 adapted to be pushed aside by a plunger 75 when a handle 81 is tilted so as to vent the hollow piston and the space above it by tilting the valve. The stem is held in its tilted position by a spring clip 65, shaped as shown in Fig. 3, sprung into a groove in the outlet 14, and continues to be held as the piston rises until a reduced portion 64 on the stem slips through the gap in the clip. The duration of opening is controlled by varying the length of the stem 57 which is made in two parts screwed together, a variable number of shims 60 being inserted between the shoulders of the two parts, or interchangeable valve stems of different lengths may be used. The upper ends of the grooves 28 in the valve 23 are restricted as shown to graduate the flow of water as the valve opens and closes. The passage 37, which is larger than the passage 45 but smaller than the passage 48, ensures a slow opening of the valve since the high pressure water entering at the passage 37 slows down the rate of fall of pressure due to the opening of the auxiliary valve 49. Fig. 9 shows a modified main valve having through passages 28<1> with restricted upper ends instead of the grooves 28, the valve fitting closely against the sleeve 16 and allowing water to flow as the holes rise clear of the upper edge of the sleeve. The parts 21, 23, 31, 40 are preferably made of non-corrosive material such as that known under the Registered Trade Mark " Bakelite."
