Title: Process for the fat-liquoring of chrome-tanned hides
IPC: C14C9/02
Filed: 1954-06-25
Abstract: 788,657. Fat-liquoring leather. BOEHME FETTCHEMIE GES. June 25, 1954 [June 27, 1953], No. 18641/54. Class 76. Chrome tanned hides are treated with a fatliquoring oil containing a masking agent which is an oil soluble partial ester or partial amide of a carboxylic acid containing 3 or more carboxyl groups, or phosphoric acid, with high molecular weight alcohols or amines, or a salt of said partial esters and partial amines. Acids specified are phosphoric, diadipic, citric, 1,2,3,4-butanetetracarboxylic, trimesic, mellitic, nitrilo-triacetic, and ethylene diamine-tetra-acetic acids, and water-soluble salts of such esters and amides. Examples of masking agents are the monododecyl ester of orthophosphoric acid, the mono-octadecyl ester of citric acid, the monododecyl ester of nitrilo-triacetic acid and the mono- and di-dodecyl esters of ethylene diamine tetra-acetic acid. Normally 2 to 20 per cent of such agents are incorporated in the fatliquoring oil. Examples relate to (1) a fatliquoring oil composed of 40 parts of sulphonated sperm oil, 40 parts of un-sulphonated sperm oil, and 10 parts of mineral oil to which was added 10 parts of the sodium salt of the monododecyl ester of ortho-phosphoric acid. 1.2 to 3.5 per cent of this composition was employed in about 200-250 per cent of liquor for the fat-liquoring of chromed tanned upper leather. (2) a fat-liquoring oil similar to (1) above contained 15 per cent of the cyclohexyl amine salt of the mono-oleyl ester of orthophosphoric acid as a masking agent, and was applied in an amount of 4-6 per cent to chromed tanned leather, the application being such that one-third of the fat-liquor oil was applied to the chromed-tanned and neutralized leather, followed by charging with 3-6 per cent of a vegetable tanning material, dyeing, and again fat-liquoring with the remainder of the fat-liquoring oil. (3) To the fat-liquoring oil of Examples (1) and (2) above 10 per cent of the ammonium salt of a mono-ester of citric acid was added in place of the masking agent mentioned. The fatty alcohol fraction used for the esterification consisted of coconut oil alcohols C 12  to C 18  chain length.

Title: Improvements in or relating to grinding wheel trueing devices
IPC: B24B53/08
Filed: 1960-05-27
Abstract: 924,393. Trueing grinding wheels. A. A. JONES & SHIPMAN Ltd., and J. HOULDSWORTH. July 17, 1961 [May 27, 1960], No. 18848/60. Class 60. A trueing device for a grinding wheel comprising a pantograph linkage 3, 5, 7, 11, Fig. 4, for transmitting the movement of a stylus tip 49, Fig. 1, in contact with a template 16 to a dressing tool 50, has means for adjusting the tip 48 relative to the axis of a shaft 17 about which the stylus is pivotable, whereby the pivot centres of the operative tips of both the stylus and tool may be adjusted relatively to compensate for errors in the setting of the dressing tool with regard to its pivot axis. The hardened nose 49 of the detachable tip 48 of the stylus plate 43 is of similar shape, in proportional size, to the dressing tool diamond tip 50, normally a circular arc. The stylus plate 43 is adjustably secured by clamping screws 37 to an arm 35, fixed to the stylus pivot shaft 17, between inner and outer plates 40, 38, the latter having a horizontal slideway 39 engaged by a rib on the inner plate 40 which may be locked by screws 41 after lateral adjustment. A vertical groove on the inner face of the plate 40 is engaged by a keyed member 42 fixed to the main stylus plate 43. A micrometer screw 44 at the lower end of the plate 40 bears on the end of the keyed member 42, contact being maintained by a tension spring 46, vertical adjustment of the stylus being effected by the micrometer screw. A handle 55 attached to an extension of the outer plate 38 enables the operator to keep the stylus in contact with the template edge. Movements of the stylus about its pivotal axis are transmitted to the tool-holder 52 by chains 19, 21, 24, and 27 on sprocket-wheels 18, 22, 25 and 27, the wheel 27 being secured to a horizontal shaft 4, the tool-holder 52 being mounted at its opposite end. The tool 51 may be rotatably adjusted in its socket to present another face of its tip 50 to the grinding wheel. A counterbalance weight 30 and tension spring 68 facilitate movements of the stylus carrying arm 11. A cradle 64 is provided for the arm 11 when not in use, the head being secured by a spring- loaded plunger 65, Fig. 3, to prevent damage during transit. The template 16 is clamped at its upper edge to the front of a box-like housing 14, Fig. 1, having on its inner rear face a pressure-plate 57 which takes the thrust produced when moving the stylus around the template; a plate 56 at the end of the pivot shaft housing makes contact with the pressure plate 57. A vertically slidable setting-bar 61 having at its lower end a trued face 62 is supported at one side of the housing 14 and may be held by a clamping screw 63 at a suitable level for setting the angular position of the stylus. The stylus plate 43 is made slightly larger than the, proportionately enlarged, dimensions of the dressing tool body to avoid contact with the grinding wheel of any part other than the tool tip.

Title: Nuclear reactor fuelling installation
IPC: G21C19/20
Filed: 1969-04-14
Abstract: 1,260,683. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. 14 April, 1969 [15 April, 1968], No. 18964/69. Heading G6C. A fuelling machine as disclosed in Specification 1,260,682 has a head L provided with a snout P which may be coupled to the lower end of a selected fuel tube of a pressurized water reactor (Fig. 1, not shown) and the head may be rotated through 90 degrees about a horizontal axis to permit coupling of the snout to a horizontal fuel supply or disposal tube (Fig. 2, not shown). The space 115 within the head L and the interiors of the magazine tubes 121, 122 must be filled with water at a temperature and pressure similar to that existing in the reactor fuel tubes or in the horizontal supply and disposal tubes, before the snout valve 108 is opened. Since the water temperature and pressure in the horizontal tubes is much lower than the temperature and pressure in the reactor fuel tubes, the condition of the water in the fuelling machine must be changed when the snout P is transferred from a reactor feed tube to a horizontal tube and vice versa. It is desirable therefore that the volume of water in the fuelling machine be kept to a minimum and to this end the top plate 120 of the magazine 102 is sealed against the space 115 by a hydrostatic annular seal 116. Thus the water is confined to the space 115 and to the interiors of the tubes 121, 122 and is unable to reach the space surrounding the tube exteriors. The water conditions in the fuelling machine are changed by the arrangement shown in Fig. 10, the head L having two bores 360, 361 connected to pipes 362, 366. The water is circulated by a pump 363 through a heat exchanger 365 and a pre-set electrically controlled pressure regulator 368. Construction of seal 116.-The seal, Fig. 9, comprises a main seal 340 and a back-up seal 341. Seal 340 comprises a fixed seal body 342 and a seal body 343 rotatable with the magazine 102 and biased by a spring 344. When the magazine is to be indexed pressurized water is admitted to a conduit 347 to reach the cavity 345 and open the seal 340.

Title: Afterburning control of internal combustion engine exhaust gas
IPC: F01N3/22
Filed: 1974-05-01
Abstract: 1469487 Secondary air supply to afterburners NISSAN MOTOR CO Ltd 1 May 1974 [19 May 1973] 19142/74 Heading B1W Secondary air for afterburning is introduced into the exhaust system of an I.C. engine the amount of air introduced being controlled in response to vacuum variations in the engine intake manifold and modified by the variations of the' vacuum at the venturi of the engine carburettor. Engine-driven air pump 16 feeds air to inlet port 22 of chamber 20 and the air passes to outlet port 25 via two diaphragm-actuated valves and fixed orifice 36. The first valve comprises seat 32 and head 40 connected by stem 40a to diaphragm 44 which defines a vacuum chamber 46 and an air chamber 56 open to atmosphere through holes 54. The valve is biassed to the closed position by spring 48. Spigot 52 connects with booster diaphragm assembly 50, which comprises vacuum chamber 62 communicating with the carburettor venturi 80, booster chamber 60 and diaphragm 58 which carries valve 66. The valve 66 controls communication between vacuum chamber 46 and a tapping 74 on the inlet manifold 72. The second valve comprises seat 34 and head 84 connected by stem 84a to diaphragm 90 which defines vacuum chamber 96 and upper chamber 92 which communicate through orifice 88 in the diaphragm. Vacuum chamber 96 communicates through port 88 with vacuum tap 74. Operation. With the engine running a given volume of air dependent on engine speed is available at port 22. If the engine speed is increased, the increased vacuum at venturi 80 causes diaphragm 58 to move towards vacuum chamber 62 and thus increases the vacuum in chamber 60 and hence in vacuum chamber 46 to unseat valve head 40, so that air flows to the exhaust system. When the throttle is closed, as during engine braking, excess air is vented by relief valve 12. During such engine braking, the inlet manifold vacuum increases but is equalised in the upper and lower chambers of the second valve, through the diaphragm orifice 88. When the engine is accelerated or the throttle is fully opened, the reduced manifold vacuum prevails in vacuum chamber 92 and the higher vacuum which still exists in the upper chamber unseats valve head 84. At idling a small quantity of air passes through orifice 36.

Title: Improvements appertaining to machines or apparatus used in the washing, bleaching and other treatment of woven and other fabrics
IPC: D06B3/16
Filed: 1930-06-24
Abstract: <PICT:0361937/IV/1> <PICT:0361937/IV/2> In a series of machines for subjecting woven fabric to washing, scouring, bleaching, and like treatment, the engagement or disengagement of the belt or clutch driving gear of any machine of the series is effected with the aid of an auxiliary power such as hydraulic, steam, or air pressure.  This pressure is turned on or shut off by a valve which is operated from a lever controlled by the tension of the fabric passing to the succeeding machine.  Thus overfeeding of fabric from one machine to the next is automatically checked.  The driving gear in the whole series of machines is so arranged that each machine, when working, pays out fabric more quickly than the succeeding machine.  In the arrangement illustrated in the drawings, the fabric a coming from a washing machine passes over a roller 6, under the roller 4, over 6a and under 4a, and then passes to the next machine.  The rollers 4, 4a are mounted on levers 2, which are pivoted upon a shaft 11 mounted on the end frame 3 of the washing machine.  A friction clutch member 8 is splined upon the main driving shaft 7 of each machine, and its corresponding member 8a is fixed upon the belt driving wheel 9, which runs loosely upon the shaft 7, so the machine is driven only when the member 8 is forced into contact with the corresponding member 8a. The member 8 is operated by the piston-rod 11a through a lever arm 10a on a shaft 19 and a fork lever 10 also on the shaft 19.  Thus, when the levers 2 and the rollers 4, 4a descend to the position w, the lever arm 14 fixed on the outer end of the shaft 11 causes the rod 15 to ascend, thereby opening up water, steam or compressed air to the lower end of the cylinder 12, forcing up the rod 11a, and disengages the clutch members 8, 8a, thus stopping the machine.  When the succeeding machine has taken up sufficient fabric to raise the levers to the position w<1>, fluid is admitted to the upper end of the cylinder 12, and the clutch is re-engaged.  In order to enable the machine to be started or stopped while the pressure is shut off, the shaft 19 carries a spring-actuated clutch 20 and hand-levers 21, 21a.  On moving either hand-lever to overcome the spring clutch, the lever 10a is also moved, and the machine put into or out of motion.
