Title: Warning apparatus for the deflation of pneumatic tyres
IPC: B60C23/04
Filed: 1937-05-07
Abstract: 480,226. Pneumatic tyres. MICHELIN & CIE. May 7, 1937, No. 13157. Convention date, May 7, 1936. [Class 144 (i)] A device for indicating tyre-deflation comprises two diaphragm valves each subject on one side to the tyre-pressure and at the other side to a slightly greater pressure, the first valve opening on a predetermined fall of pressure in the tyre to control the opening of the second valve whereby an audible signal is actuated. In the form shown, compressed air is supplied through the nozzle 1 to a chamber 41 which communicates through passage 6 with space 43 surrounding the signal-operating valve A3. The upper end of the chamber 41 is fitted with a spring-loaded diaphragm 3 having a small aperture 4 leading to the chamber S1 which opens to atmosphere by vent 101. The air admitted to chamber 41 lifts the diaphragm 3 to close the aperture 4, by contact with a plug 5, and then passes through port 6 to space 43, passage 10, space 42, and tyre-connecting nipple 7. On predetermined fall of pressure in the tyre, the diaphragm 3 is forced from the plug 5 thereby opening the space 43 to atmosphere through the port 101. The pressure in the tyre then operates, through port 11, to lift membrane 53 surrounding the valve A3 so that air escapes from the tyre through port 12, which is of larger cross-section than port 11, and funnel 8 to atmosphere. The resultant vibration of the membrane 53 at the port 12 gives an audible signal until the reduced tyrepressure is insufficient to lift the membrane. To restrict escape of air from an inflated tyre during fitment to replace the deflated tyre, a valve-device C is provided to connect the space 43 with the tyre and hold the membrane 53 to its seat, thereby shutting-off communication with the venting-space 41. The valve C comprises a spring-loaded head 13 which is pressed off its seat, by means of a button 15, to open the air-circuit 7, 17, 18 and space 43. Specification 445,643, [Group XXIX], is referred to.

April 29, 1930, No. 13162. Convention date, May 1, 1929. [Classes 97 (i), 98 (i), and 98 (ii).] To provide exposure data for use in printing photographic sound-film records, latent images 5, Fig. 2, of sensitometric strips are formed on the unused sensitized film by exposing a vacant portion of the film to a varying light admitted through a slot 11, Fig. 4, while the film moves at a predetermined speed substantially equal to that at which it is moved during subsequent exposure to produce the sound record on another portion of the film. The latent images of the strip and sound record are thus formed under similar light conditions and the images are produced together when the film is developed. In the apparatus shown in Fig. 4, the slot 11 is progressively varied by a logarithmic cam 15 and the strip exposures on the film 1 occur either end to end or at intervals determined by a slotted disc 28. The film is accurately perforated at the time of making the exposures by a stamp 24, the strips varying in exposure longitudinally in accurate dimensional relationship to the perforations 2. A stepped cam may replace the cam 15 to provide the strips with graded sections. Fig 8. shows a photometer with adjustable diaphragm 47 for measuring in terms of gamma (the slope of the Hurter and Driffield curve) the density difference at spaced points of the developed film.

Title: Improvements in ink drop writing systems
IPC: H04N1/034
Filed: 1969-03-13
Abstract: 1,210,203. Selective printing. A. B. DICK CO. 13 March, 1969 [13 March, 1968], No. 13383/69. Heading B6F. [Also in Divisions G4-G6] An ink drop writing system of the kind in which ink drops 22 are formed in a stream in synchronization with synchronization signals, and are charged in accordance with synchronized video representative signals to be subsequently deflected in an electric field by an amount depending upon the charge and then caused to impinge on a writing medium, is provided with means for testing and correcting the phasing of the ink drops relative to the video representative signals. The testing and correcting means comprises means for applying a fixed frequency test signal synchronized with the synchronizing signal for charging the stream of drops in place of the video representative signals, a detector 76 so placed as to receive drops charged by the test signal only when the phasing of the drops is correct and means responsive to the detector output for adjusting the phase of formation of the ink drops so that the detector does receive drops. The ink drop writer moves across the width of the printreceiving paper on a screw (44, Fig. 2) rotated by a motor and gearing first in one direction and then in the other to return the writer to its home position. The stream of ink drops passes between a pair of elongated deflector electrodes 41, extending across the width of the paper, to which the video representative signals are applied. A feeler (74, Fig. 2) operating a sensing switch detects when the ink drop writer is in the home position, in which position it is aligned with the detector 76. The drops 22 are formed from a jet 20, drop formation being controlled by a transducer 14. As a drop is formed it should if correctly timed be charged by a test signal applied to the charging tunnel 24. If while the ink drop writer is in the home position the drop formation is out of phase with the test signal the drops are uncharged or insufficiently charged. If the drops are properly charged, they are deflected by the synchronous signals applied to the electrodes to strike detector 76. The detector may be of piezoelectric material generating a pulse for each drop. These are amplified and applied to an integrator 90. If there is no integrator signal after the ink drop writer has been in the home position for a certain period a phase control circuit changes by 180 degrees the phase of the test signal being applied to the drop control transducer 14. This brings the drops into correct phase with the charging signals applied to tunnel 24. The deflector plates are energized by a 66 KHz signal which may be reduced to 33 KHz before being applied to the charging tunnel 24. Drops are formed at 66 KHz so that alternate ones are charged and uncharged. The uncharged drops reduce interference between the adjacent charged drops. The detector may be some other form of senser e.g. a microswitch.

Title: Electric circuit interrupters
IPC: H01H33/12
Filed: 1962-04-09
Abstract: 964,827. Gas-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. April 9, 1962 [April 17, 1961], No.13516/62. Heading H2B. In a gas-blast circuit-breaker having impedance shunted main contacts and auxiliary contacts for interrupting the residual current, the arced gas is filtered prior to subsequent re-use of the gas. In Fig. 4 a multi-break " groundedtank circuit-breaker has a singleblast valve 22 which feeds a plurality of interceptor units 20 each comprising a fixed contact 35, an intermediate contact 34 and a movable contact 33. The latter is connected to a cross-bar 32 of a ladder-like operating arrangement generally similar to that described in Specification 885,932. In the closed position (Fig. 3, not shown) contact 33 engages fingers 57 of contact 34 so that its other end 59 is urged into engagement with fixed contact 35 against the bias of a spring 36 within a filter housing 47. When the circuit-breaker is opened the arm 59 opens the blast valve 22 and contacts 33 are moved to the left by springs (not shown) so that the intermediate contact 34 is moved by its spring 36 to remain in engagement with contact 33 until stops 61, 62 engage. During this movement main contacts 34, 35 separate and the arc 39 formed between these contacts is shunted by an impedance 40 of helically wound high resistance tubing supported on insulating rods 42 and connected between the housing 47 and an end casting 44 on which the fixed contact 35 is mounted. Blast gas acting on the arc 39 is directed by an insulating flow director 49 into the interior 50 of the contact 34 so that it passes through passages 51 into the housing 47 and through filter 48 into the main container (not shown). Gas from the main container is recompressed and returned to high-pressure chamber 21 in a manner similar to that described in Specification 948,698. Continued movement of contacts 33 separates auxiliary contacts 33, 34 forming a residual arc 53 which is acted on by gas passing from the contact interior 50 through passages 63. An alternative arrangement (Fig. 5, not shown), generally similar to Fig. 2 of Specification 948,698, has a resistance connection between main and auxiliary contacts.
