Title: Apparatus for prefabricating building panels
Inventor: MACLEAN NEIL GORDON
IPC: E04G21/22
Filed: 1968-05-14
Abstract: 1,217,369. Moulding panels. COAL INDUSTRY (PATENTS) Ltd. 13 May, 1969 [14 May, 1968], No. 22827/68. Heading B5A. Apparatus for forming a panel if elements e.g. bricks or concrete blocks, joined by cement, includes a mould 1 and a trolley 9 for carrying the elements; the trolley is movable relative the mould and includes an adjustable template means 13 for determineing the relative positions of the elements placed in the mould. As shown the trolley runs along the tops of the mould sides 2 and the template means 13 comprises parallel prongs 15 extending rearwardly from a vertically adjustable transverse beam 22, and spaced apart a distance equal to the height of an element plus the thickness of a cement fillet. Plates 16 of half the length of an element are interposed between alternate pairs of prongs. A masking material, e.g. a foam sheet, is first placed on the mould base, and the elements are transferred from the trolley on to the sheet in a predetermined position by the template means. As shown, the trolley moves from right to left and may be driven or manually moved in increments equal to the length of an element plug the length of a cement fillet. After laying a complete panel of elements mortar is poured into the spaces between them; a further layer of masking material is placed over the formed panel and the template means raised to allow the trolley to be moved back to commence the assembly of a further panel. The mould height may be built up in stages to provide for the production of further panels, one above the other. Completed panels may be lifted from the mould by lifting apparatus carried along a monorail located above the mould.

Title: Process for the preparation of sulphuric esters of cellulose
IPC: C08B5/14
Filed: 1928-08-09
Abstract: 303,493. Ruth-Aldo Co., Inc., (Assignees of Orioli, E.). Jan. 6, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cellulose sulphates and other cellulose esters; preparatory treatment of raw cellulosic materials. - Cellulose sulphates are prepared by treating cellulose with sulphuric acid anhydride under such conditions that no appreciable amount of organic cellulose ester is formed, or the amount. of organic ester formed is proportionately less than that of the sulphate. The reaction mixture preferably includes a diluent, such as the acid corresponding to the anhydride employed or an organic solvent such as benzene. In an example, cellulose containing 2 per cent of moisture is treated with a mixture of sulphuric acid, acetic anhydride, and glacial acetic acid. After several hours, the reaction product is squeezed and washed with benzene or other neutral organic solvent. It may then be dried in vacuo or used directly, for instance, in the preparation of other cellulose esters; it may also be used directly before squeezing.

Title: Improvements in apparatus for treating liquids with chemical reagents
IPC: C02F1/68
Filed: 1922-08-24
Abstract: 207,267. Paterson, W. Aug. 24, 1922. Mixing fluids and solids with fluids in flow. - Relates to the treatment of liquids with chemical reagents by apparatus in which the flow of liquid is measured by a weir, Venturi meter, or otherwise, and consists in utilizing such means to control electric means directly or indirectly effecting the addition of the reagent in proportion to the rate of flow of the liquid. The invention also consists in the provision of means for varying the rate of addition of the reagent with or without interfering with the continuous operation of the apparatus. As shown, the liquid flow is measured by a weir having a float b which actuates a rheostat c that controls the speed of an electric motor d. The motor actuates a solid reagent distributor e and a pump f drawing from a liquid reagent tank g. The rate of addition of the reagent may be varied by increasing or decreasing the voltage of the current supplied to the motor or, in the case of a solid reagent, by varying the speed of the distributor. Specification 191,762 is referred to.

Snapping tackle for a straight-bar machine comprises a snapper for each yarn, each of which is mounted on a separate shaft 1, 2, 3, which is oscillated when a yarn is operative to take up and remove the slack at the end of each carrier traverse. Each shaft is provided with an arm 4, 5, 6 coupled by a rod 7, 8, 9 to a slide 10, 11, 12 which is moved up and down by inserting a tappet 24 between the end of the slide and the upper end of a continuously reciprocating rod 17, 18, 19 so that by introducing or removing the tappet the corresponding snapper may be rendered operative or inoperative. The rods 17, 18, 19 are coupled to one arm of a lever 21 operated from the cam-shaft 33. The tappets are inserted by the pull of solenoids 30, 31, 32 against a spring 36. In addition, one or more of the tappets may be inserted and retained in position by a handoperated lever 39 to avoid the necessity of maintaining a solenoid energized when one or more carriers are in continuous operation.
