Title: Improvements in the manufacture of radiators for motors and like tubular devices
IPC: B21D53/04
Filed: 1923-05-31
Abstract: 198,679. Gillison, T. May 31, 1922, [Convention date]. Plate apparatus.-In motor-car radiators emp 1 o y i n g corrugated strips which form air tubes and water passages. When assembled the strips are formed with regular corrugations of sine form as to their central parts and bent either to a semicircular or a semi-hexagonal formation at their front and rear edges. The semicircular ends 14 shown, abut when the strips are assembled and the angular corrugations 12 are held apart forming vertical water passages 19 surrounding air passages 16. The pairs of strips when assembled are folded together at top and bottom and alternate ends are bent over as at 17 or corrugated as at 18 and the front and rear faces dipped in solder. When the ends are formed in a semi-hexagonal shape the strips are joined in pairs to form a water passage between each two strips and not air passages as in the formation shown.

Abstract: 858,735. Friction clutches. FORD MOTOR CO. Ltd. April 28, 1959 [April 28, 1958], No. 14475/59. Class 80 (2). [Also in Group XXIX] In a combined torque converter and planet gear wherein a rear disc clutch 56 between a planet gear input shaft 32 and a front sun 50 is engaged in opposition to a spring 78 by direct action of an annular piston 58 of a fluid pressure servo, the cylinder of which is formed in one half 54 of the clutch 56, a restricted axial passage 86 in the piston 58 vents residual fluid from the servo when the latter is de-energized, thereby preventing undesirable clutch drag due to centrifugal pressure, and a non-return ball valve 96 in an axial passage 94 of larger diameter than, and positioned radially inwards of, the passage 86 permits replacement of the vented fluid by air at atmospheric pressure whilst inhibiting transfer of energizing fluid from the servo. This admission of air through the valve 96 ensures that the system fluid feed lines are not vented but remain filled with non- aerated fluid. The passage 86 has a smaller flow capacity than that of the servo feed lines to permit pressure build-up behind the piston 58 and communicates with one of piston recesses 84 which are blanked by the clutch discs when the clutch is engaged. The passage 94 has a relatively larger portion 92 holding the valve ball 96 which is retained by suitable deformation of the mouth of the portion 92. The piston 58 may be grooved at 88 to receive a fluid seal. The gearing is the same as that described in Specifications 704,787 and 803,667

The strips 21 to 24 are attached to the margins 15, 17 by rivets 19 which move in similar slots. In a first embodiment (Fig. 2) the position of the lasting margins 15, 17 is determined by a U-shaped spring 30 which can be opened up to vary the width of the shoe by cam 32 which can be turned by a screwdriver. In a second embodiment (Fig. 9) the position of the margins 15<SP>1</SP>, 17<SP>1</SP> is determined by a cable 60 which has its ends secured to the rivets 28<SP>1</SP> and which passes through rings 62, 64.

Such monomers are prepared by reacting glycidyl acrylate or methacrylate with an optionally substituted hydroxy or carboxylated azobenzene in the presence of an alkali metal hydroxide or of a basic salt of an alkali metal, e.g. sodium bicarbonate or carbonate. A polymerization inhibitor such as benzoquinone or hydroquinone or its monomethyl ether may be employed if necessary.  Among many monomers of which the preparation is described in examples are 2-hydroxy-3-(5-phenylazo - 2 - hydroxybenzoyloxy) propyl methacrylate and 2-hydroxy-3-(4-[4-methylphenylazo] phenoxy) propyl methacrylate. The above monomers may be copolymerized with other ethylenically unsaturated polymers to provide polymers which are stable to ultra-violet light and coloured (see Division C3).ALSO:The invention comprises a copolymer of an ethylenically unsaturated azobenzene derivative corresponding to the formula <FORM:1006884/C3/1> wherein R1 and R2 are radicals of the benzene series consisting either of a phenylene or napththylene radical, wherein Z is an ethylenically unsaturated group which is either a beta-hydroxy-propyl acrylate or a beta-hydroxy-propyl methacrylate group and X and Y represent hydrogen or an alkyl, aryl acyloxy, aralkyl, alkoxy, hydroxy or halogen radical and A represents either oxygen or a carboxy radical (see Division C4) and an ethylenically unsaturated monomer.

Title: Improved process for the treatment of magnesian materials
IPC: C01F5/24
Filed: 1945-06-14
Abstract: A process for the continuous preparation of magnesium and calcium carbonates from ores such as dolomites, magnesium limestomes, predazzites, pencatites and impure magnesites, comprises passing an aqueous slurry of the calcined ore through a series of carbonation tanks in which the supply of carbon dioxide gas is controlled to maintain a series of descending pH values ranging from 12.5 to 8, the pH value in each zone being maintained substantially constant, and separating the magnesium and calcium carbonates found either by a method dependent on their differences in specific gravity, e.g., centrifugal separation, or by a method of froth flotation.  The ore is calcined at, for example, 840 DEG  or 885 DEG C., to leave part of the calcium carbonate undissociated, after pulverising and classifying to give a product with an average size of about 12 microns, is suspended in water in a ratio of 1 part partly calcined ore to at least 10 parts, e.g., 12 to 16 parts, water.  This suspension is passed through a series of carbonation tanks, of which, e.g., the first three and last three are larger than the middle five and are provided with agitators to give gentle agitation and circulation in the larger and rapid agitation and passage in the smaller tank.  The carbonating gas, of 20 to 40 per cent. carbon dioxide, may be derived from the ore calcination and may be scrubbed and compressed before being delivered to all tanks except the first through small elastic-walled orifices (see Groups VI and XII).  The temperature should be kept between 20 DEG  and 50 DEG C. to form nesquehonite, for example, between 25 DEG  and 36 DEG C., and the temperatures of the second and third tanks are used to control the gas supply thereto.  The supply to the remainder is controlled by the pH in the tanks, the pH values maintained thereby being, for example, 12.1, 9.8, 9.6, 9.1, 8.6, 8.3 and 8.  The magnesium carbonate produced is composed of crystals about 100 microns in length and 8 to 12 microns in breadth, and the calcium carbonate of particles about 10 microns in diameter.
