Title: Improvements in or relating to hydraulic valves
IPC: A01B63/10
Filed: 1960-08-02
Abstract: 879,790. Tractor power lift mechanisms. FORD MOTOR CO. Ltd. Aug. 2, 1960 [Aug. 13, 1959], No. 26681/60. Class 79(1). A tractor has a pair of double acting hydraulic cylinders connected respectively to left and right hand implement sections controlled by a handle which has movement in two angularly disposed paths; movement in one path operating a remote cylinder control valve and movement in the other, preferably orthogonal path, operating a distributer or selector valve. As shown in Fig. 1 right hand cylinder 19 operates right hand :implement section 20 through a link-work and is controlled by hydraulic lines from control valve 15 and selector valve 16. These valves are bolted as a unit to a cover of the tractor centre housing, preferably connected to hydraulic pressure and return lines in the housing by bolts 35 having internal passages. A valve operating lever 62 (Figs. 4 and 5) is pivoted on a horizontal pin 77 to lever 66 which pivots on a vertical spindle 67 in a 'bearing member 69 bolted to the tractor housing. Horizontal and vertical notches in the end of the lever 66 engage end 73 and pin 72 of a lever 64 which is pivoted at pin 65 and engages one enn of spool 40 of the cylinder control valve. This valve is preferably of the type which automatically returns to the neutral position when the piston has completed its stroke. Horizontal movement of the lever 62 controls the position of spool 40 and hence the control valve action and cylinder movement. A spherical ball 75 on lever 62 is received in a socket 79 of a lever 80 pivoted on pin 81 and engaging spool 46 of the distributer valve 16. Movement of spool 46 and hence the distributer valve action is controlled by vertical movement of lever 62. Figs. 7, 8, 9 (not shown) show diagrammatically the connections between the distributer valve and cylinders for the different modes of operation. To give more rapid operation of the cylinders they are arranged in series when operating together (Fig. 8) but, when raising the implement sections by supplying fluid from valve 16 to the left hand cylinder, because of the volume displaced by the piston rod, the left hand piston will complete its stroke before the other one has done so. To allow the second piston to finish its stroke a shuttle valve is fitted to the left hand piston which opens when a stem portion contacts the end of the cylinder allowing flow through the shuttle piston. The valve also operates when the implements are lowered. Specification 688,073 is referred to.

Title: Improvements in and relating to dispensing í¡í¡ flexible sheet material
IPC: A47K10/36
Filed: 1955-09-19
Abstract: 837,194. Towel dispensers. CHEESMAN, J.J. Aug. 22. 1956 [Sept. 19, 1955], No. 26713/55. Class 18. [Also in Groups VIII and XL(b)] A cabinet for dispensing paper towelling has a recess 10, Fig. 3., across its front face with shelf 11 on to which a portion of towelling severed from a roll 19 is fed, the picking up of which portion by the user actuates the mechanism to feed a fresh portion. The shelf 11 is supported by spring side brackets 12 and a series of guiding tongues 13 projecting into corresponding circumferential grooves 14 of a roller 15, so that the shelf pivots through sidebrackets 11a about the spindle-ends of this roller. An upper roller 16, for metering and severing a length of towelling equal in length to its circumference, is geared to roller 15 through pinions 15a and 16a at both ends. The web of towelling is led from a supply-roll 19, Fig. 3, occupying the lower part of the cabinet beneath a tensioning bar 18 around an auxiliary roller 17 and delivered between rollers 15 and 16 on to the shelf 11. When the shelf 11 is depressed by the user removing a portion of towelling resting thereon, a bracket 27 on the under side of the shelf thrusts on a spring plunger 26 having a pawl 25 engaging in the set of teeth 24, which rotates the shaft 22 to operate a switch and energize a motor 20, causing the rollers 15 and 16 to revolve so that a metered portion of towelling is delivered on to the shelf 11 for the next user. A rotating arm 29 moves in correspondence with the metering roller 16 to open the switch when the roller has completed its rotation. During the rotation of roller 16, the web is severed or partially severed by a blade 30, Fig. 5, mounted within the roller 16 in a longitudinal slot 35, being urged to project by compression springs 36 around guide pins 37 extending from the back of the blade across a bore 38 of the roller into slideable engagement in holes 39. Automatic projection and retraction of the blade in conjunction with the rotation of the roller is effected by a cam device at each end of the roller assembly, consisting of a pin 40 projecting from the end of the blade through a radial slot 41 of the roller and into engagement with a fixed internal cam plate 42 contoured to hold the blade normally retracted against springs 36 but permitting it to snap out at the appropriate time followed by return to its retracted position. Alternative operation of the switch can be effected by means of an electric eye located in a side wall of recess 10.

Title: Production of paraformaldehyde
IPC: C08G2/08
Filed: 1950-11-03
Abstract: <PICT:0682737/III/1> Aqueous formaldehyde solution is concentrated by feeding it to a still and condensing the vaporous head product in at least three stages.  The first two condensates are returned to the still whilst the final condensate comprises a concentrated formaldehyde solution which on cooling produces paraformaldehyde.  A 10-30 per cent aqueous formaldehyde solution is fed via line 3 to a still 4 operating at 30-45 p.s.i. gauge.  The head product passes through a pressure reducer 5 where the pressure is reduced to 5-15 p.s.i. absolute, then to a condenser 6 and then to a cyclone separator 7. Liquid from the separator 7 is returned to the still via lines 9 and 3 whilst uncondensed vapour passes to a second separator 11. Uncondensed vapour from the separator 11 passes to a third condenser 12 and then to a cyclone separator 13.  Liquid from separators 11 and 13 is returned to the still as reflux via lines 16 and 18.  Uncondensed vapour from separator 13 passes to a water-cooled condenser 20 (see Group VI) where it is totally condensed.  The vapour flow through the condensers and cyclone separators is maintained by a steam jet 26.  Condensate from the condenser 20 passes to a vessel 25, where it remains for some time, and then to a drum cooler 28 on which it solidifies to paraformaldehyde.
