Title: Improvements relating to gas-driven liquid pumps
Inventor: HILL DAVID CUSHING
IPC: F01L25/06
Filed: 1964-06-01
Abstract: 1,014,571. Reciprocating pumps. HASKEL ENGINEERING & SUPPLY CO. June 1, 1964, No. 22597/64. Heading F1A A pump comprises a gas-driven reciprocating motor piston 12 secured to a pump piston 13 slidable in a combined bearing and seal 17 of sufficient length to preclude the pump piston 13 contacting a cylinder 14 in communication with a fluid pumping compartment 18, and an assembly of valves 30 automatically operative to supply gas from a source 75 alternately to each side of the piston 12 to cause reciprocation thereof. Liquid to be pumped is admitted to the compartment 18 through a check valve 21 and is discharged therefrom through a check valve 22. The valve assembly 30 controlling reciprocation of the motor piston 12 comprises a valve 60 having a spool 51 and spring loaded pilot valves 31, 41 which are alternately opened by the motor piston 12. As shown, gas is supplied to the motor piston upperside 12a from the source 75, through a groove 71 in the spool 51 and a conduit 65, to cause a downward pumping stroke of the piston 13. Gas is exhausted from the motor piston underside 12b through a conduit 67, a groove 72, a radial aperture 57 and an axial passage 56 in the spool 51 communicating with an outlet 77. Completion of the pumping stroke opens the pilot valve 41 so that gas passes from the source 75 through a conduit 62 to act on the lower face 54a of the spool 51 which then moves to its upper position. Thereafter gas passes to the motor piston underside 12b via the groove 72, and the conduit 67 to initiate the suction stroke; and gas is exhausted from the upperside 12a through the conduit 65, the groove 71, a radial passage 55, the axial passage 56 and the outlet 77. Completion of the suction stroke opens the pilot valve 31 whereby the gas pressure acting on the face 54a is relieved through conduits 63, 76 to allow the spool 51 to move to its lower position under the action of gas acting on its upper annular end 53a through a conduit 61.

Title: Improvements in and relating to means for limiting fluid leakage through joints and bearings in internal combustion engines
IPC: F02M63/00
Filed: 1921-08-26
Abstract: 169,155. Williams Motors, Inc., (Assignees of Shaw, L. E.). Sept. 16, 1920, [Convention date]. Stuffing-boxes, substitutes for; connected to source of high pressure.-In internal-combustion engines, leakage of air through a moving joint is prevented by connecting a passage surrounding the moving part to the source of combustiblemixture. The sleeve 4, through which the stem of the inlet valve 3 parses, is formed with a chamber 10 connected by perforations with a passage 12 opening at 14 into the inlet pipe at the carburettor side of the throttle valve. In a revolving-cylinder engine in which the explosive mixture passes from the carburettor 23 through a port 24 to the interior of the crank shaft and by a port 25 and a pipe 20 to the inlet valve. Rings 34 fitting the crank shaft and spaced by bolts 37 are arranged at each side of the port 25. The rings are secured by a nut in a recess in the cylinder casting 33 and are packed by washers 38, with sufficient friction to prevent rotation, but to permit lateral adjustment. Grooves 35 in the rings 34 are connected with the interior of the crank-shaft by passages 43. The port 25 is controlled by a sleeve 28, which, however, in every position leaves the ports 24 and 43 open.

Title: Manufacture of new monoazo-dyestuffs
IPC: C09B43/12
Filed: 1949-09-02
Abstract: Monoazo dyestuffs of the general formula <FORM:0672734/IV (c)/1> (wherein A represents an acylamino group and the phenyl residue is free from substituents) are manufactured by (a) coupling a diazotized 4-nitro-6-acylamino-2-aminophenol in an alkaline medium with 1-phenylamino-8-naphthol-4-sulphonic acid, or (b) treating a dyestuff of the general formula above, but in which A represents a nitro group, with an alkali sulphide or hydrosulphide to reduce the nitro group at A to an amino group and acylating this by means of an acid halide or anhydride.  The acyl residue may be any of those enumerated in Specification 666,047, [Group IV (a)], and the products may be metallized in substance, in the dyebath or on the fibre as indicated therein.  Examples describe the preparation, by method (a), of dyestuffs in which A is acetylamino, n-butyrylamino and benzoylamino, and the dyeing of wool green by the after-chroming process with the second of these dyestuffs.  Specifications 424,453 and 438,131 also are referred to.  A sample has been furnished under Sect. 2 (5) of the dyestuff obtained by coupling diazotized 4 : 6 - dinitro - 2 - aminophenol with 1 - phenylamino - 8 - naphthol - 4 - sulphonic acid, reducing the product with sodium hydrosulphide and acylating the resulting amino group with acetic anhydride.  The Specification as open to inspection under Sect. 91 comprises also the use of coupling components containing a substituent in the phenyl radical, e.g. 1-(p-tolylamino)-8-naphthol-4-sulphonic acid.  This subject-matter does not appear in the Specification as accepted.

A mask electrode is removably mounted adjacent a cathode-ray tube face-plate, on support studs which project from the sidewall of the tube envelope, by spring straps each of which has an aperture at one end fitted on to a corresponding one of the studs, the electrode having a portion in which the other end of at least one of the spring straps is engaged, permitting accurate alignment of that strap aperture with its stud prior to the permanent attachement of the strap to the electrode. A hook-shaped plate 36 is welded to the midpoint of each side of the frame 26 of a shadow mask electrode 24, such that the hook portion 37 can receive and frictionally engage one end of a support spring 29, the other end of which is apertured to receive the frusto-conical tip of a support stud 22 mounted on the face-plate sidewall 14. The electrode is then positioned, by movement of the spring portion 33 within the hooks 37 to space and align it exactly with respect to the face-plate, whereafter the springs are welded to the plates 36. The end portions 33 of the springs are manufactured with an initial curvature, to counteract bowing produced during assembly and thereby ensure an adequate area of contact with plate 36 for effective welding; alternatively, the plate 36 may be suitably curved (Fig. 11, not shown). In further embodiments, the hook portion 37 is in two parts, located one at the end and one at the side of the plate 36 (Figs. 6 and 7, not shown); plate 36 may be spaced sideways from the edge of the frame flange, with off-set extensions, including the hook portion, welded to the flange (Figs. 8 and 9, not shown); and the spring may be secured to the frame merely by inserting an off-set end portion through a slot formed in the frame flange (Fig. 10, not shown).
