Abstract: 535,079. Fluid-pressure servomotor-control systems. VICKERS, Inc. Oct. 14, 1939, No. 27917. Convention date, Oct. 15, 1938. [Class 135] A member controlling the operation of a fluid pressure operated power device is remotely controlled by two members arranged in a second hydraulic circuit, one member being operatively connected to the first-mentioned member and the second with the primary control member and both adapted to vary the same characteristics of the fluid in the second hydraulic circuit. The figure shows the invention applied to a hydro-electric marine steering gear. The rudder is operated by a double-acting power cylinder 18 supplied with pressure fluid by a variable displacement pump 12 driven by an electric motor 10. The controlling yoke 28 is coupled by a link 32 and floating follow-up lever 30 to a rod 22 secured to the power piston and to a control rod 35 attached to a differential piston 80 preferably having one face twice the area of the other. An auxiliary pump 36 driven by the motor 10 supplies fluid through a flow regulator 50 and conduits 62, 82 to the larger side of the piston and directly through a conduit 84 to the smaller side. The conduit 62 is also connected through a second flow regulator 50<SP>1</SP> to a return conduit 66. Each regulator comprises a variable orifice 56 and a piston-actuated valve 58 for maintaining a constant difference of pressure across the orifice. The variable throttle 56<SP>1</SP> is actuated by the steering wheel 74 acting through a pinion 72 and toothed sector 70 to vary the discharge through the conduit 62 and so initiate movement of the piston 80. Movement of the piston 80 acts through a lever 68 to vary the throttle 56 in the direction required to vary the supply to correspond with the altered discharge. Branch pipes 86, 88 on the conduit 48 fitted with non-return valves 90, 92 lead to the variable displacement pump to make good any losses.

Abstract: 781,948. Making grid electrodes; shearing. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 22, 1955 [Sept. 29, 1954], No. 28033/54. Classes 83 (2) and 83 (4). In order to ensure that when cutting a helical wire winding into lengths, each length has the correct number of turns, markers are arranged on the winding or its support and a cutting device is actuated when each marker reaches a control point. Wire 1 is wound on supports 2 to form a winding of sufficient length to make, say ten grid electrodes. The wire 1 is located in notches in the supports 2 and the notches are pressed over to grip the wire excepting at the places where the wire is to be cut where one or two turns are left loose. Markers 3 of insulating material are deposited adjacent where the cuts are to be made. The winding is hot or cold stretched and then placed in a holder 4 which is fed forward by a motor 10 driving through a clutch 14. When a contact 16 rides upon one of the markers 3, the circuit of a relay 15 is broken and a solenoid 17 is energized to release the clutch 14 to stop the feed. The cutting device is operated. After a delay determined by a dashpot 18, the clutch 14 is engaged and the winding is fed past the cutting device. It may be arranged that after each cut a second cut is made to cut off a short piece of one of the supports 2 which piece may include the marker. The markers may be projections which mechanically control the feed.

Abstract: 274,802. Telefonaktiebolaget L. M. Ericsson, (formerly Allmanna Telefonaktiebolaget L. M. Ericsson). July 22, 1926, [Convention date]. Condensers having systems of plates set at right angles to the axis of rotation, and wherein the outer contours of the plates intersect one another at a distance from the axis of rotation varying with the angle of rotation, have the active surfaces of their plates distributed asymmetrically on both sides of the maximum radius, which, as shown in Fig. 2, is OP or OP<1>. The Specification develops and illustrates the known type of plate giving a straightline frequency relation and states that the disadvantages of bulkiness and relatively high minimum capacity are obviated by a plate of the contour shown. The pivot point O is preferably in the middle of the base line AB and the edge AP is preferably normal to it. The radius R of the plate is obtained as usual from the derivative of the capacity in respect of the angle a of rotation, provided the inner radius r is known. The radius R is then set off at an angle # from the base radius OB<1>, this angle being equal to (a-v), a where cos v= - R.

Title: Improvements in or relating to method of and machine for producing screw threads in two oppositely disposed conical surfaces of a work piece
IPC: B23G1/32
Filed: 1930-09-23
Abstract: 361,050. Milling screws. SOKAL, S., 1, Great James Street, Bedford Row, London.-(Hasse & Wrede Ges., C. ; 116A, Christianiastrasse, Berlin.) Sept. 23, 1930, No. 28483. [Class 83 (iii).] In cutting screw threads on work-pieces having two oppositely disposed conical surfaces, such as pipe-couplings, a continuous thread over the apex of the conical surfaces is produced by two milling - cutters having annular series of teeth and acting simultaneously from both ends of the work, an axial feed equal to the pitch of the thread being given to the work. The work is mounted in a worm-driven chuck 18 rotatable on a head 17 which is angularly adjustable on a saddle 16 bv means of bolts and arcuate slots 26. The milling- cutters 12, 13 are rotatably carried by heads 7 transversely adjustable by means of cams and screws (not shown), on saddles 3 which are adjustable along ways 1 by racks and pinions 5 and handwheels 4. In operation, one cutter is adjusted longitudinally so that it projects several threads beyond the apex of one cone and the other cutter is adjusted to an exact pitch-distance therefrom by means of a gauge comprising a pin 8, Fig. 5, attached to a base 9 having a V-notch for engaging one cutter-spindle to set the< >pin 8 parallel thereto and a flat surface for engaging the other spindle. The length of the pin 8 is an exact multiple of the pitch of the thread being cut and each cutter terminates in a flat surface a passing through the outer base points of the last tooth. A scale 14, graduated in pitch divisions, is then adjusted along the head 7 until a pointer 15 secured to 'the bed registers with a graduation thereon, the scale then being secured to the head. The second cutter is next moved axially, after the gauge 8 has been removed, and the cutters moved laterally so as to clear each other, until its inner end projects beyond the apex of the work and the pointer 15 registers with a graduation on the scale 14, thus ensuring that the cutters will both produce the same helix on the work. The cutters are then Ted laterally until they contact with the work and are adjusted to the correct depth of cut by scales on the slides, adjustable stops being provided to limit the depth of cut after the initial adjustment. Chucks.-The chuck consists of a drum 18 carrying three concentric jaws 21 operated simultaneously by a toothed ring 24, right- and left-hand screws 22 and wedges 23, and also carrying three independent jaws 25. The jaws 21 are first actuated to grip the work lightly, the jaws 25 are then closed to grip the work lightly and prevent its distortion whilst the jaws 21 are tightened securely, after which the jaws 25 are also tightened.

Title: Process and apparatus for drying substances in vacuum drying installations to a predetermined moisture content
IPC: F26B25/22
Filed: 1970-06-12
Abstract: 1275833 Controlled drying process FARBENFABRIKEN BAYER AG 12 June 1970 [13 June 1969] 28493/70 Heading F4G [Also in Division G1] A process for drying a material in a vacuum drying chamber relies on #p/#t, the rate of change of equilibrium vapour pressure of the solvent with time, as an indication of the completeness of the drying operation. In one form of the process (Fig. 2) the chamber 2 is evacuated from ambient pressure through p w  to p w  - #p, both pressures being able to be pre-set; p w  is the desired final equilibrium vapour pressure of the solvent and #p is a small increment. The values are chosen using the relationship between p and the moisture content of the material. When the pressure has reached the lower level, valve 3 is opened allowing the pressure p to be measured at a position 7 while the temperature T is measured by a thermometer 6. The measurements are then relayed to converters 7a and 6a respectively which feed a circuit 10 which calculates a value # proportional to the relative humidity in the chamber. The signal then passes to a controller 11 which can be set to the two values # w  and # w  - ## such that the controller closes valve 3 for ### w -## and opens it for #># w . The valve 3 allows the chamber 2 to be evacuated by the pump 5 via a condenser 4. At first the rise in pressure such as a to b is rapid because the material is wet but later the rise is slower; when the rise-time exceeds a chosen value #t max  the drying process is deemed to be complete. An alternative scheme (Fig. 3, not shown) allows the valve to operate at fixed, equal intervals of time, the process finishing when the rise of pressure between the opening and closing of the value is not greater than a certain #p min .
