Title: Improvements in regulating devices for tuning vibratable mechanical systems, especially material-testing apparatus
IPC: G01M7/02
Filed: 1956-07-19
Abstract: 821,858. Automatic control systems for mechanical vibrators. LOSENHAUSENWERK DUSSELDORFER MASCHINENBAU A.G. July 19, 1956 [Sept. 16, 1955], No. 22350/56. Class 38 (4). In a mechanical vibrator, e.g. for testing materials, the vibrating mass produces a measuring voltage which is in phase with the vibration of the mass, and the phase of the measuring voltage is compared with the phase of the sine wave voltage producing the vibrations, and the natural frequency of the mechanical system is altered in dependence upon the phase difference between the two voltages. In this way, when the frequency of the exciting voltage is changed the mechanical resonance of the system is correspondingly changed. As shown, a vibrating table is mounted by means of a disc 2 between two annular air pads 3, 4, which are held in an annular frame 5, the air pads being connected together by tubes 31. The table is excited in known manner from a sine wave generator 6 via an amplifier 7. A device 9, fixed to the vibrating table, produces a measuring voltage which is in phase with the vibrations of the table and is fed to a phasecomparing device 10 which is also supplied with the exciting voltage. There is normally a phase difference of 90 degrees between the two voltages when the system is in resonance, variations from this value producing a positive or negative voltage which via amplifier 11 and servomotor 12 controls a rotary valve 13. The valve 13 controls a passage 14 open to the atmosphere, a passage 15 communicating with the air pads, and a passage 16 connected to a compressed-air pipe, the air pads being connected to the pressure pipe 16 or with the atmosphere via 14 according to whether the servomotor is actuated by a positive or a negative voltage.

Patent GB-501012-A (GB)
Title: Improvements in and connected with the treatment of liquids
IPC: C02F1/52
Filed: 1937-08-16
Abstract: 501,012. Photo - -electric apparatus for testing turbidity of liquids. SYMONDS, G. B. L. Aug. 16, 1937, No. 22448. Convention date, Aug. 26, 1936. [Class 40 (iii)] [Also in Groups I and XXXV]. Water sewage or other liquid which has been dosed with coagulant and subjected to flock-conditioning treatment is examined by light-sensitive apparatus in order to determine the adequacy of the coagulant, added. The testing means may control automatically the device which supplies the coagulant. As shown the liquid under treatment is supplied through a pipe 14, Fig. 1, to a central tube 13 in a settling tank 10. Coagulant is delivered from a hopper 21 by a vibrating shoot 22. Coagulation is promoted by gentle agitation in the tube 13 due to paddles 16 on a shaft 15 rotated from an electric motor 17 by reduction gear 17<1>. A comparatively small portion of the liquid to which coagulant has been added is withdrawn from above the paddles 16 by a tube 34 and delivered to a smaller settling tank 80 with central tube 27 and paddles 28 rotated from a motor 30. The partially cleared liquid over-flowing from the tank 80 is passed through a channel 35 in which is a movable casing 40, Fig. 2, containing, an electrical lamp and having a glass window 41. A beam of light passing through the liquid in the trough and a glass window 42 at the end of the trough falls on a photo-electric cell 43, the circuit of which is connected through a galvanometer 49 to the circuit of an automatic balancing potentiometer, which embodies a slide-wire resistance 47 and a pivoted arm 48. Movements of the arm 48 are communicated by a mechanical or electric connection 53 to a contact arm 52 in the circuit of an electromagnet 23 controlling the vibrations of the shoot 22 and to rheostats 58, 76 in the circuits of the motors 17, 30 respectively. The amount of coagulant added and the speed of the paddles in the tubes 13, 27, is thus regulated according to the opacity of the liquid in the trough 35. Means may be provided for automatically adjusting the position of the casing 40 in unison with the adjustment of the pace of the paddles 16, 28. Under clockwork control adjustment of the arm 48 takes place at such intervals that one adjustment has full effect in the apparatus before another adjustment takes place. With the arrangement shown in Figs. 4 the.ourrent of a photo-electric cell 63 amplified by a triode 73 is forced through the coil of an electromagnet 64 governing a switch arm 65 which causes, lamps 72, 70, 69 to be lit accordingly as the liquid is being correctly dosed with coagulant, under-dosed or overdosed. The means for adding coagulant may then be adjusted normally. Alternatively, the dosing apparatus may be controlled by a reversing motor, the switch of which is operated by an electromagnet 74 in the circuit of the lamp 70 and a similar electromagnet in the circuit of the lamp 69. To accentuate the variations in light conductivity of the liquid in the trough 35, dye may be added to the liquid as it passes to the tank 80.

Title: Improved method and apparatus for grinding threaded members such as taps and the like
IPC: B24B19/02
Filed: 1924-05-12
Abstract: 239,859. Hanson, B. M. W. May 21, 1923, [Convention date]. Turning.-The thread of a screw or tap is ground by a tool having several annular cutting- edges or serrations, which operate simultaneously on several convolutions of the thread and are so formed as to provide spaces between the grinding- tool and the convolutions of the thread. The serrations are of different sizes or shapes, so that as the tool passes along the work, each serration removes a small portion from the thread, the last serration grinding the thread to size. The serrations are shaped by means of diamond points 35 - - 37, mounted on a slide 38, and movable across the faces of the serrations by screws 42. When grinding a thread of large lead angle the axis of the grinding-tool is inclined perpendicularly to the lead angle; the wheel is then trued whilst so inclined.

Abstract: 1,002,133. Printing apparatus; feeding webs. ADOLPH GOTTSCHO Inc. June 1, 1964 [June 10, 1963], No. 22573/64. Headings B6B and B6C. Apparatus for printing on a web W, Fig. 1, of material as it passes from a supply roll 12 to a machine 14 such as a wrapping machine which takes in the web at varying speeds, comprises a printing roller 74 and an impression roller 44, which also draw the web from the roll 12, the roller 74 being driven from a motor 120, the speed of which is controlled in accordance with the speed at which the web is fed in the wrapping machine. The motor 120 is coupled by a chain drive 110 to the shaft 102 of an ink-fountain roller, the shaft 102 being geared to the shaft of the printing roller 74 which has rubber bearer rings 80, Fig. 8, to rotate the impression roller. The web W passes from the printing apparatus over a floating roller 50 maintained horizontal by gears thereon engaging vertical racks. An extension of the roller 50 moves in slots 134 in an arm 132 attached to the actuating shaft of a variable transformer 126 interposed between the source of electric current and the motor 120. Anticlockwise movement of the arm 132 caused by upward movement of the roller 50 operates the transformer so as to increase the voltage applied to and the speed of the motor 120. Similarly, a downward movement of the roller 50 causes a decrease in the motor speed. In the lowest position of the roller, the arm 132 operates a switch to open the circuit of the motor, i.e. when the machine 14 is not running. The printing roller 74, Fig. 8, is free on its shaft 82 and is pressed axially towards its drive gear 88 by a spring 86, the gear having a radial slot engaged by the head of a screw on the roller to couple the gear and roller together. Specification 868,168 is referred to.
