Filed: 1920-10-29
Abstract: 155,569. Signal Ges. Dec. 15, 1919, [Convention date]. Addition to 148,972. Subaqueous audible signals.-In the arrange. ment shown in Fig. 2, in which a diaphragm M is associated with a structure comprising masses G1, G2, G3 and elastic connecting-rods E1, E2, there are two oscillatory systems to be considered, the first consisting of the masses G1, G2 and rod E, and the second consisting of the masses G2, G3 and rod E2. The invention consists in tuning these two systems to one another. There may be more than two such systems, and the diaphragm itself may have resonance and be tuned to the same frequency. The mass G3 includes the effective mass of the diaphragm and of the water which moves with it, and may or may not include an additional mass fixed to the diaphragm as shown. In the constructional form shown in Fig. 3, the masses G1, G2, G3 are connected by rod-and-tube couplings so as to lie close together, and the mass G1 carries exciting and polarizing coils S1, S2, the mass G2 acting as an armature. Alternatively, any two of the masses, or all three, may carry exciting coils. The elastic members may be in the form of diaphragms or springs instead of rods. The system as a whole may have a resonance curve with a broad crest made up of a number of adjacent peaks.

Title: Improvements in or relating to counting mechanisms
IPC: G06M1/04
Filed: 1948-11-30
Abstract: 670,595. Counting-apparatus. DAVIS, WYNN & ANDREWS, Ltd., and ANDREWS, T. D. H. Nov. 15, 1949 [Nov. 30, 1948], No. 30997/48. Class 106 (i). A high-speed counting-apparatus, especially for pulse counting in radio-active measurements, comprises a rotatable element, e.g. a pointer 11, operated step-wise to indicate units, and a separate coaxial-drum counter 12 operated step-wise by the rotatable element to indicate the number of revolutions completed. The pointer 11 is operated by the mechanism described in Specification 670,587 and comprising a ratchet wheel 17 on the pointer shaft driven step-wise by an escapement lever 16 oscillated by a magnet 15. A snail cam 20 on the pointer shaft is engaged by a spring-actuated follower lever 22 pivoted at 23 and connected by a link 30 with the actuating arm 31 of the counter 12, which incorporates a ratchet drive between the arm and numeral drums. As the pointer 11 makes the final step of each revolution, a radial step in the cam 20 releases the follower lever 22 to the action of its spring 24 so that the counter 12 is advanced one unit. The pointer 11 is zeroized by turning it back, by means of a knob 41, to a position slightly beyond the zero in which position it is arrested by the radial step in the cam abutting the engagement nose of the follower lever 22. The escapement lever 16, which is spring actuated, then restores the pointer to the zero position. The counter 12 is separately zeroized by a handle 40.

Title: Improvements in and relating to dumpers
IPC: E02F3/348
Filed: 1955-11-01
Abstract: 786,546. Shovelling apparatus. KLAUS, K. Nov. 1, 1955 [Nov. 16, 1954; Nov. 16, 1954; Feb. 4, 1955; April 25, 1955], No. 31214/54. Class 68(1) A pair of arms 7 is rotatably mounted about an horizontal axis 5 on the chassis 6 of a dumper having an open top, forwardly tiltable container 2 at the front of the chassis and supports a shovel 8 that together with the arms is forwardly directed beyond fhe chassis when the shovel is to be filled and, when the arms are swung upwardly and rearwardly, can discharge either into the container 2 or into an independent materialreceiving means 20 dependent upon the position of the arms. Four specific constructions of such a combined shovelling machine and dumper are described. In the first construction a spring is stressed when the arms 7 pass rearwards through the vertical as a rope 11 passing over a fixed pulley 19 is wound on to a winch 12 so that on the release of the rope from the winch the spring returns the arms forwards past the vertical and then gravity returns said arms to a loading position. To permit of an improved line of pull, the rope is connected to an upwardly projecting member 16 secured to one of the arms. The second construction is a modification of the first construction in which each arm 7 is formed of two parts 17, 27 pivotally connected at 37 and provided with locking means at 14 and 15 so that the parts can be rotated about the axis 5 as an integral structure or the part 27 can be rotated about the pivotal axis 37 to load the material-receiving means 20 or the container 2 dependent as to whether the locking means 15 or 14 are rendered effective. In a third construction to permit of loading of either the container 2 or the container 20 each arm is an integral structure that is actuated by a compressed airactuated jack of which the cylinder is pivotally connected to an eccentric disc rotatably mounted on the chassis and the piston rod is connected to one or the other of two points at different distances from the axis 5 in a rearward extension of each arm or an arm secured to a rotatable shaft to which the arms are secured. Two containers are arranged longitudinally and on either side of the driver's seat and one is subdivided into two compartments, one compartment containing fuel for the engine of the damper-shovelling machine and the other containing compressed air. This latter compartment is connected by valve-controlled conduits to the jacks and to the other container through two oppositely acting non-return valve-controlled conduits. The fourth construction results from modifying the third construction by forming each arm of two telescopic parts. The shovel may be replaced by a grader blade.

Title: Intermittent motion device
IPC: G03B1/18
Filed: 1965-07-22
Abstract: 1,061,607. Magnetic couplings. NATIONAL CASH REGISTER CO. July 22, 1965 [Aug. 3, 1964], No. 31304/65. Heading H2A. [Also in Divisions B6 and G2] An electromagnetic clutch in which both members are similarly toothed to produce a cogging effect is used to induce torsional oscillations in a shaft so that its output end experiences dwells that may be used for printing or motion picture projection at very high speed. As shown applied to a serial printer, shaft 3, driven by belt 13, carries a flywheel 8 at one end and a light type-wheel 10 at the other having raised characters 10a printing by means of a hammer (17, Fig. 5) on to a pressuresensitive paper 18, 19. The shaft thus acts as a torsion spring between the flywheel, and the type-wheel which has a stepped motion of the same net speed. The magnetic clutch 20 consists of a toothed armature 21 on the rotor, the number of teeth being equal to the number of characters on wheel 10, and a similarly toothed stator excited by coil 27. The stator rocks on the shaft axis, against spring restraint, in ballbearings 30. In doing this it provides a feedback control signal at sensor 34. The paper indexing mechanism is similar to a Geneva mechanism (Figs. 5 and 6, not shown) in which a shaft 42, driven from the main motor of the device, carries an eccentric pin 42b engaging between lobes 49a of wheel 49 driving the tape 18 and detented by a sprung roll 59. This roll is coupled to a switch 65. The end 70 of the flywheel is coated with a nickel-cobalt magnetic recording layer on which character pulses corresponding to the characters on wheel 10 are recorded by magnetic head 71. An additional pulse on the flywheel serves to trigger an electronic counter 300 at each revolution (Fig. 12, not shown) to control the operation of the hammer. Printing occurs during one revolution of the flywheel and paper-advance and print hammer restoration during the following revolution. A parallel printer (Figs. 21, 22, not shown) consists of a drum 132 carrying 120 columns of evenly-spaced raised characters around its circumference, and torsion bars 134, 135 and clutches 136, 137 at each end. The oscillation is sensed by crystal pick-up 153, for the control of 120 print-hammers (not shown) acting on the drum. In a helical printer (Fig. 23) the characters are arranged helically on the drum to save time in hammer indexing or to enable the print-paper to move axially of the drum. Other arrangements (Figs. 24-28, not shown) are described. As applied to a motion-picture projector (Figs. 17-20, not shown), the film advance sprocket 90 and a flywheel 93 are driven by a torsion shaft 92. The inertia of the flywheel is adjusted by radial set-screws 96. A similar, but heavier flywheel 97 is secured to the other end of the torsion shaft and to the rotor 101 of the electromagnetic clutch whose rotor 105 is angularly adjustable by means of screw 120. The torsion shaft is driven by pulley 77 at a nodal point on the shaft.

Title: Improvements in or relating to jacquard devices applicable to knitting machines
IPC: D04B15/66
Filed: 1929-10-15
Abstract: 341,476. Knitting-machines. MARTIN, C. S., KILBOURN, S. L. and BERRIDGE & CO., Ltd., I. L., 43, Humberstone Road, Leicester. Oct. 15, 1929, No. 31329. [Class 74 (ii).] Pattern mechanism for controlling other pattern mechanism or for performing other operations in connection with mechanical knitting comprises a set of feelers 12 selected by perforations in a travelling band 11 and a corresponding set of sliders 16 each of which is latched against movement or unlatched by a feeler. The sliders when freed are moved by springs to operative positions where they are again latched. The rise 128 of a cam 28 acting on a follower 29 carried by an arm 30 causes a projection 125 thereon to engage a pin 33 and thereby raise a gate 31 until the notches thereon register with the sliders 16. A continuation of the movement operates a bail 25 to reset such sliders 16 as have been previously selected. A vertical rise 37 then engages a follower 6 6 and clears the feelers 12 from the perforations in the band 11 by lifting a plate 14 on which they rest. A follower 48 is next engaged whereby a sector 45 is rocked and a pawl 41 advances the platen 10 one step. The plate 14 is then released to allow the ends of the feelers 12 to drop on or through the band and the surfaces 328, 428 allow the bail to recede, and permits the sliders 16 corresponding to the selected feelers to move endwise unc.er influence of their springs. When the follower 29 runs off the continuation cam 428 the bail comes out far enough to allow the gate 31 to drop and lock the sliders in their innermost and outermost portions according to selection. Specification 330,612, [Class 74 (ii), Knitting &c.], is referred to.

Title: Hydraulic control system for the automatic reopening of a pipe line valve
IPC: F16K31/12
Filed: 1957-10-08
Abstract: 869,635. Fluid-pressure servomotor-control systems. SHAFER VALVE CO. net. 8, 1957 [Oct. 17, 1956], No. 31420/57. Class 135. An hydraulic system for controlling a valve in a pipe line comprises an hydraulic motor and a control valve for operating the motor to close the main valve when a pre-determined rate of pressure drop occurs in the pipe line, characterized by pressure-responsive control-unit for actuating the control valve to operate the motor to re-open the valve after pressure has been restored in the pipe line. The main valve 10 which may be of the rotary plug type is actuated by a vane-type hydraulic motor 15 supplied with motive fluid from a control unit 16 via conduits 39 and 39<SP>1</SP>. The motive fluid may be gas or air or liquid under pressure or may, as shown, be derived from the pipe line through the conduit 19 and double check valve 21 which ensures that if a pressure differential exists in the pipe line sections 11 and 12 the higher pressure will always be fed through the conduit 19. A reservoir 54 is charged by the conduit 19 to supply a reserve of power when the pipe-line pressure . falls. The conduit 19 leads to a chamber 23 in the control unit 16 and according to the setting of two poppet valves 28 and 28<SP>1</SP> motive fluid is directed to one or other of the conduits 39, 39<SP>1</SP>. The poppet valves 28, 28<SP>1</SP> are actuated by a lever 32 pivoting about a point 33 of the control unit housing. Pressure in the pipe line is sensed by a diaphragm 35, biased by a spring 34 to the left, and communicating with the main pipe by a conduit 59. The conduit 59 also charges a reservoir 63 via a variable restriction 65. When a predetermined rate of pressure drop occurs in the pipe line, the rate being determined by the setting of the variable restriction 65, the diaphragm 35 will move to the right, causing the spindle 30 to rock the lever 32 to depress the plunger 34 and open the poppet valve 28. This action will direct motive fluid along conduit 39 to operate the hydraulic motor to close the main valve 10. The closing action of the main valve 10 opens a shut-off valve 85 in conduit 81. If pressure is subsequently restored in the pipe-line the reservoir 87 will be chaiged through the conduit 81 at a rate depending on the setting of a variable restriction 84 and a variable bleed orifice 87 in the reservoir 86. When the pressure in the reservoir 86 reaches a value determined by the setting of a valve 83 the valve will lift, permitting fluid to pass from the reservoir to move a piston 76 to the right. Movement of the spindle 76<SP>1</SP> will rock the lever 32 in a clockwise direction to depress the plunger 34<SP>1</SP> and open poppet valve 28<SP>1</SP>. This action will direct motive fluid along conduit 39<SP>1</SP> to operate the hydraulic motor to re-open the main valve 10. The control unit 16 may also be operated by manual actuation of the lever 32. The main valve 10 may also be actuated manually by means of a selector valve 44 and hand pump 43.
