Patent GB-455654-A (GB)
Title: Improvements in or relating to the production of plasticised cellulose ester compositions
IPC: C08L1/10
Filed: 1935-04-26
Abstract: Granular cellulose ester compositions particularly suitable for moulding purposes are obtained by kneading, in the absence of any substantial proportion of volatile solvent, a mixture comprising a cellulose ester and a plasticizer under positive pressure for a time sufficient only to produce a homogeneous, cellulous, friable mass which is then broken down to granular form.  Kneading may be effected in a screw stuffer device or a masticator mixer provided with pressure ram and very small clearance between the mixing blades and the adjacent walls.  The process may be carried out at temperatures rising as a result of the kneading up to about 86 DEG  C.  The time of treatment may be as short as 1--5 minutes.  After the kneading treatment, the mass may be ground without waiting for it to cool, and a hammer-mill, rotary mill, or three-roll mill may be used.  The cellulose ester to be treated may be in flake or other form which is readily comminuted.  It may be cellulose acetate, nitrate, formate, or propionate.  Pigments may be subjected to a preliminary grinding in a ballmill with one of the ingredients of the mixture.  The product may be used in processes of rolling, cake pressing, extrusion, and dope-making.  In examples, cellulose acetate is mixed with dimethoxy-ethyl phthalate, dimethyl phthalate, p-toluene sulphonamide, glycol monomethyl ether, triphenyl phosphate, triacetine, tripropionine, methyl or ethyl acetanilide, dibutyl tartrate, dimethoxy-ethyl adipate dimethoxyethyl benzoyl benzoate, diglyceryl tetracetate, diethyl phthalate, chlorinated naphthalenes, tributyl or tricresyl phosphate, xylene monomethyl or ethyl-p-toluene sulphonamide, or methyl phthalyl ethyl glycollate, as plasticizer. The following pigments and fillers are added: titanium oxide, madder lake, alizarine purple lake, cadmium yellow, chromium oxide, national fast acid blue, rhodamine BX, cadmium red, bronze powder, pearl essence, asbestos, terra alba, clay, gypsum, fibres, waxes, soaps, and resins.  Small proportions of water or ethyl alcohol may be present.

Title: Electrohydraulic control apparatus
IPC: F15B13/043
Filed: 1972-03-17
Abstract: 1349329 Electro-hydraulic control apparatus ROBERT BOSH GmbH 17 March 1972 [17 March 1971] 12616/72 Heading F1P [Also in Division G3P]  Electro-hydraulic control apparatus 9 comprises a servo-control unit 11 controlling a valve 10 which determines supply and discharge rates to and from a hydraulic load 29. Unit 11 includes a differential piston 35 connected to a control valve spool 18, movement of piston 35 being controlled by three solenoid-operated valves 46, 49, 52 monitored by instructions from inductive transducers 43, 57 to an electronic control unit. Springs 39, 40 normally bias piston 35 into a neutral position, wherein supply and return lines 13, 14 are cut off from load 29 to hydraulically lock the same, valve 52 being closed and valves 46, 49 being open so that chambers 36, 37 are connected to each other and exhaust. If leftward movement of spool 18 is required, to move piston 30 of device 29 to the left, then a desired position transducer 57 feeds a signal to unit 56 where the signal is compared with another signal from actual position transducer 43. Valve 52 is opened and valve 49 closed while valve 46 remains open. Fluid from inlet 13 thus flows to both chambers 36, 37 and differential forces on the piston 35 move it leftwards to the desired position wherein valves 52 and 49 are both closed to hydraulically lock piston 35. Movement to the right is obtained by opening valves 52, 49 and closing valve 46 so that inlet fluid flows to annular chamber 36 and chamber 37 is connected to the return 14. In an alternative embodiment, valves 46, 49 are replaced by a single solenoid-operated 3-position, 4-way valve Fig. 2, (not shown).

The "thin" and "thick" layers constitute respectively a minor and a major proportion of the total thickness of the plated Cu. Annealing may be at 600C or above for at least 30 mins e.g. in He-Ar mixture. The helix may be supported on a cylindrical rotatable roller made of or coated with PVC or polyethylene, which has at least one helical groove therein for receiving the band. The groove may be covered at its base with a Cu strip connected at each end to a current source, and adjacent turns of the groove may be separated by a non-conducting web. The band is unwound from the support for annealing.

Title: Improvements in or relating to fluid oscillator systems

Abstract: 985,700. Controlling fluid flow. R. E. BOWLES, and B. M. HORTON. April 10,1961 [April 8, 1960], No. 12838/61. Heading G3H. A pure fluid device for producing oscillations in output conduits 121, 122, Fig. 3, has a nozzle 16a to provide a power stream of fluid and control nozzles 17a, 18a connected with the output conduits by channels having capacitances 22, 23, 24 and resistances in the form of porous plugs 31, 31a, 31b, 31c. Flow of the power stream to one of the output conduits 121,122 causes the delayed application of a control signal at one of the nozzles 17a, 18a to switch the power stream to the other outlet. As shown, the device is such that the power stream tends to follow either wall 15a, 15b by boundary layer action until such action is interrupted by a control stream, but the walls may be shaped to avoid boundary layer action so that the direction of the power stream is the result of momentum exchange between the power stream and a control stream. A cascade arrangement is described in which the output conduits of a first device feed the control nozzles of a second device, the feedback paths lead from the outputs of the second device to the control nozzles of the first device, and the feedback paths on each side are interconnected with each other at points near the control nozzles of the first device. Asymmetrical devices having a feedback path and control nozzle for one side only are described, and these are provided with an adjustable telescopic tube associated with the feedback path for tuning purposes. In cases where the feedback path crosses from an output at one side to a control nozzle at the opposite side it is formed in a plane perpendicular to the main plane of the device. The feedback path may contain a resilient wall to adapt the device for use with incompressible fluids. Fig. 4 illustrates a modification in which junctions in the feedback paths 33, 34,35,36 have outlets to sump or ambient pressure fitted with porous plugs 37, 38, 39. In the arrangement shown in Fig. 12 a feedback path, containing a restriction 133, leads from each output 121,122 to a control nozzle 130, 131 on the opposite side,and tuning passages 17,18 is connected to sources of pressure through adjustable valves 93 are provided. This arrangement will provide low frequency oscillations of substantially square wave form, but a squarer wave form can be obtained by connecting the outputs to the control nozzles of a bi-stable pure fluid device. Specifications 970,985,975,019 and 975,020 are referred to.

Abstract: 571,602. Variable speed gearing. SHAW, L. E. Aug. 9, 1943, No. 12853. [Class 80 (ii)] In variable-speed gearing embodying expanding belt-pulleys and a countershaft, the,distance between the countershaft and the axes of the driving and driven shafts is varied automatically with the change in speed ratio. As shown, pulleys 6, 14 on coaxial driving and driven shafts 1, 4 are connected by belts 34, 35 to pulleys 36, 37 on a countershaft 31. The latter is carried by a member 44 pivoted to a bar 50 and has an adjusting screw 52. The bar 50 can slide vertically and has at its lower end a cam 54 engaging a roller 55 on a yoke 22 pivoted at 23 in the casing 3. The yoke 22 carries rollers 21 lying between thrust bearings 18, 19 carrying the movable sheaves 9, 16 of the pulleys 6, 14. Upon angular movement of the yoke 22 by a hand lever 25 movement is given to either sheave 9 or 16 whereupon the movable sheaves of the other three pulleys move to correspond to change the gear ratio. At the same time the roller 55 acts on the cam 54 to slide the bar 50 and maintain constant the belt tensions. An indicator 63 on an arm 64 fixed to the yoke 22 moves over a scale 61 to indicate the speed ratio.
