Abstract: 1,071,543. Measuring pressure electrically. MICROMATIC HONE CORPORATION. Feb. 17, 1965 [March 11, 1964], No.6815/65. Heading G1N. A variable capacitance pressure transducer includes a housing 12, 16, 14, Fig. 2, an adjustably fixed electrode 28, and a flexible electrode 22 subjected to fluid pressure through an opening 40. The position of the fixed electrode 28 is adjustable by means of at least three screws 30, which are held in tension over the range of adjustment by resilient washers 38; and the electrode 22 effectively divides the interior of the housing into two chambers 20a, and 20b. The two electrodes may alternatively be cantilevered from an off-axis position in the housing Fig. 4 (not shown), an insulating block (76) with a bolt (78) and an insulating sleeve (108) being used to retain the electrodes (72, 74). In this case the fixed electrode (72) is adjusted by screws (88) which engage an insulating member (86) attached to the electrode, and the position of the movable electrode is varied by means of a pin (80) connected thereto and bearing on a bellows (66) subjected to the fluid pressure to be measured. A sealing ring (68) associated with the bellows divides the interior of the housing (52, 54, 56) into two chambers (60, and 64). A coaxial output connector is provided in the housing in both cases, the central pin thereof being connected to one electrode by a wire 46, Fig. 2 (105, Fig. 4 (not shown)), and the outer shell being connected to the other electrode via the housing.

Title: Spring action driving gear with variable torque for on-load changeover switches of regulating transformers
IPC: H01H9/00
Filed: 1951-03-22
Abstract: 705,845. Snap-action switches. JANSEN, B. March 22, 1951, No. 6936/51. Class 38(5) The contact-carrying shaft M of an on-load tapchanging switch is moved from one position to the other by a torque which is initially large, which then decreases to a small value at and after the .middle position, and which finally increases to a medium value. A link A fixed to the shaft has a slot L engaged by a roller R on a link B pivoted at m, the link B being latched in its end positions by levers Kl<SP>1</SP>, Kl<SP>2</SP>. A spring F, which connects the link B to a lever D also pivoted at m, is stressed by an operating member C which eventually strikes a lever 4 to cause the operative latch to be released, so that the link B flies over to its other position under the action of the spring, taking the link A with it. The changing angle between links B, A and the changing lever arm of link A due to movement of the roller R in slot L are stated to produce the desired torque from the spring which is described as having an inherent straight line characteristic dropping from the initial large value to the final medium value.

Title: Improvements in and relating to luminescent-screen apparatus for recording and observing oscillations such as cardiac pulsations
IPC: G01R13/04
Filed: 1940-04-22
Abstract: 539,870. Applicatiens of luminescence. ASHER. G., and HOECKER, F. E. April 22, 1940, No. 7235, [Class 39 (i)] [Also in Group XIX] A device for making a transient record of lowfrequency vibrations or pulsations, particularly for use in connection with electrocardiographs, comprises an endless screen of luminescent material with means to move it in a path transverse to the path of travel of a light beam moved by the vibrations so that a transient glowing record which may be viewed in full is produced by the beam on the screen. As shown the apparatus comprises a casing in which an endless strip 22 coated with luminescent material, for example zinc sulphide, is mounted on a resilient support or apron 26 which maintains it taut. It is moved by a sprocket 36 driven by a clockwork motor and engaging perforations in its edges. The light beam 10 from an electrocardiograph enters through an aperture 18 and is focused on the strip by a lens 20, the image thus formed on the bottom run of the film being viewed through an aperture 16 offset forwardly from the front edge of the upper run. A screen 30 obscures the upper run of the film from view. The strip is sufficiently long to permit complete loss of the glow before any point of the record again reaches the aperture 16. In another form, the screen is formed on the inner face of the cylindrical wall of a shallow drum or dish-shaped member which is rotated by an electric motor. The galvanometer, lamp and shield which confines the view of the screen to the part on which the newly-made record is formed are all mounted on the inside of a hinged lid of a casing and lie within the drum, when the lid is closed for use of the apparatus,

Title: Rotating memory clock recorder
IPC: G11B27/36
Filed: 1969-02-11
Abstract: 1,215,128. Magnetic data stores. SINGERGENERAL PRECISION INC. 11 Feb., 1969 [15 March, 1968], No. 7288/69. Heading G4C. A clock recorder, for writing a pre-selected number of clock pulses on a rotating memory, records an origin pulse on a first memory track after providing an erase current of predetermined duration, a first rotational occurrence of the origin pulse starting a variable-frequency oscillator to produce pulses for recording on a second track, a stop signal being produced when a counter indicates a pre-selected number of pulses have been produced, the oscillator frequency being corrected in accordance with the time difference between the stop signal and the second rotational occurrence of the origin pulse to produce on the second track an equal distribution of the pre-selected number of pulses. In Fig. 1, pressing a start button (top) erases a first track of a magnetic drum or disc store and records an origin pulse on it, using head 14, which also reads the origin pulse on each subsequent revolution to reverse a flipflop 20. Setting of flip-flop 20 starts oscillator 22 to drive counter 24 the stages of which are each connected by a respective manual switch 26 to a count decode matrix 28 or via a write amplifier 30 to a write head 32 for recording on a second track, as desired. When the required number of pulses have been recorded, count decode matrix 28 resets a flop-flop 34. The difference in timing (positive or negative) between the resetting of flip-flop 34 and the resetting of flip-flop 20 is detected by logic 46 to adjust the oscillator 22 frequency via operational integrator 48. When eventually the flip-flops 20, 34 are reset simultaneously, indicating that the clock pulses on the second track are uniformly spaced over the whole track (ignoring pulse jitter) AND 54 reverses a flipflop 56 to stop recording and light a lamp 60. AND 42 responds to the reset outputs of flipflops 20, 34 to reset a flip-flop 38 thereby stopping oscillator 22 and resetting counter 24. Fig. 2 (not shown) shows some of the same circuitry used for transferring the clock on the second track to the first, as follows. Each clock pulse from the second track is read by head 32 to reverse flip-flop 20, the set state of which starts oscillator 22 the pulses from which pass via counter 24 and flip-flops to time-comparison with the resetting of flip-flop 20 in logic 46 to adjust the oscillator 22 frequency via integerator 48. The oscillator 22 is thus brought into synchronism and since the integrator 48 has a time constant long compared with the memory revolution period, pulse jitter is eliminated. The pulses from the counter are then recorded on the first track by head 14, a lamp being lit when this has been done.

Abstract: 269,505. Anode Rubber Co., Ltd. April 14, 1926, [Convention date]. Latex, treating.-In the electrophoretic deposition of rubber &c., the liberation of gas at the cathode is prevented, for example, by means of an oxidizing depolarizing agent such as lead peroxide. A lead cathode may be coated with peroxide by the usual storage battery process, and when spent may be reoxidized. Apparatus for the production of inner tubes comprises a twopart annular mould 11<a>, 11<b>, lined with zinc, or a porous depositing surface, forming an anode, and a cathode 1 consisting of a split ring attached to a spindle 7 passing through an insulating stuffing- box 8 on the anode. The cathode 1 preferably consists of a perforated iron pipe coated with lead the surface of which has been converted into peroxide. To prevent crumbling, the cathode may be covered with a layer permeable to liquids, such as gelatine. In operation, the mould is filled with a rubber, gutta &c. dispersion, which may be vulcanized, through the hollow spindle 7 and cathode 1 until the overflow 9 is reached. If desired, circulation of the liquid may be maintained. A current is passed through the latex &c., and when a sufficient thickness of rubber is deposited, the mould is swung into the position shown in broken line about a horizontal spindle, the liquid is drained off, and a drying current of hot air is passed through the spindle 7, and escapes at 9.
