IPC: F04B1/07
Filed: 1929-01-28
Abstract: 328,333. Heide, H. C., (Cincinnati Milling Machine Co.). Jan. 28, 1929. Multiple delivery piston pumps with two varr@s in series, combined with singleacting suction-valveless bucket pump. - A pump comprises pairs of connected cylinders e, f with eccentric - actuated pistons, arranged radially and delivering to an eccentricactuated constant displacement high-pressure pump H which also acts as a valve, operated bv an adjustable eccentricacting successively to connect cylinders simultaneouslv with intake 28 and delivery 40. The eccentric 9 is angularly variable with respect to eccentric 8 by hand lever 2G and gear wheels, and as the two passages 6 intercommunicate, the phase difference may be set so that pistons e and f work together or neutralize each other, or for any pressure in between as desired. The valves K and L correspond in construction and function to the valves L and M described in Specification 297,104, [Class 69 (ii), Hydraulic presses &c.]. Fluid is forced from a gear-wheel pump G through passage 33 to an annular chamber 35, through ports 36 and axial passage 37 in pump piston 39 and through a ball-valve 41 on inward movement of plunger 29 to the cylinder 7. The pressure of this fluid causes the plunger 29 to move in and keep contact with its eccentric 32 on the rotating shaft G. When the eccentric 32 forces piston 29 out it forces fluid from cylinder 7 past ball-valve 38, down passage 39 to port 40 communicating through a valve system K with the delivery of variable displacement pump S. The pump S comprises the series of radial pistons e, f operated by eccentrics 8, 9 on the common shaft G and draws in fluid from the delivery of gearwheel pump G by way of port 28 and annular cutaway 29<c> in plunger 29 to ports 6. This fluid pressure keeps pistons e, f in contact with their eccentrics. On outward movement of pistons e, f the fluid is forced back through ports 6 and cutaway 29<c> (which has now moved up) to delivery 27 which is in communication with the delivery 40 of the piston pump 29.

Filed: 1944-02-21
Abstract: 580,442. Variable-speed gearing. PRICKETT, T. C. Feb. 21, 1944, No. 3221. [Class 80 (ii)] A fluid coupling is combined with two groups of planetary gearing, each of which provides two or more speeds, one, a high-speed group, being arranged between the secondary member of the coupling and the final driven shaft and the other, a low-speed group, being adapted when required to drive the secondary member of the coupling positively from the primary coupling member. As shown, the primary member of the coupling (not shown) is connected to a flange 5 of a sleeve 20 carrying sun pinions 20A, 20B of a low-speed group of gears 9 which drives on to the shaft 6 of the secondary member of the coupling through a carrier member 11. Thus by operating brake bands 15 or 16 or a clutch (not shown) between members 21 and 22 two reduced speeds of the shaft 6 and a direct drive can be obtained from the primary member of the coupling. The shaft 6 then drives, through gear group 10, a final driven shaft 32, two more ratios and a direct drive being obtained by the operation of brake bands 17 or 18 or a clutch (not shown) between members 14 and 19. For the higher speed ratios the gear group 10 only is employed being driven by the shaft 6 through the fluid coupling, the gear group 9 being allowed to run idly by disengagement of its brake bands and clutch. A resilient or magnetic drive may be arranged between the primary member of the coupling and the flange 5.

Patent GB-430837-A (GB)
Title: Improvements in or relating to the manufacture of artificial structures from cellulose
IPC: D01F11/02
Filed: 1934-02-01
Abstract: In a process for the manufacture of artificial structures such as artificial threads or fibres from cellulose the structures in their initial form with or without prior rinsing are treated with a chemical agent which in a single operation performs the several actions, namely washing, and/or neutralizing, bleaching, and removal of any by-products and decomposition products which may be present, necessary for bringing the structures to the completed state except for a possible rinsing and drying.  In the case of structures formed from viscose solutions, a hot dilute solution of sodium sulphite is a suitable agent.  In an example artificial fibres from viscose after formation, and while in the spinning pots, or on bobbins, or as hanks are treated with a 2 per cent sodium sulphite solution at 60--65 DEG C.  The solution desulphurizes the fibres, neutralizes acid from the precipitating bath, evolves sulphur dioxide which has a bleaching effect on the fibres and dissolves salts contained in the fibres. The process is applicable to lustrous or non-lustrous artificial silk.
