Title: Method and apparatus for use in monitoring the thickness of a coating on a web
Inventor: EDGE RODNEY JAMES
IPC: G01B11/06
Filed: 1968-07-09
Abstract: 1,271,798. Measuring thickness photoelectrically. VACUUM METALLURGICAL DEVELOPMENTS Ltd. July 9, 1969 [July 9, 1968], No. 32638/68. Heading G1A. The thickness of metal vacuum deposited on a web is monitored by passing light from a source through the coated web to a photo-sensitive detector which is connected to give an indication of the metal thickness. Preferably the monitoring process takes place in the vacuum chamber which has a wall 6 with a window 5. Light from source 1 is focused by lenses 2, 3 through heat filter 4 and window 5 on to the end of a bundle of optical light guides 7 held in aluminium block 8. The individual guides are disposed across the surface of travelling web 11 on to which metal has been deposited so that each detector 12 is energized by light leaving the corresponding light guide end 10. The detectors are preferably photo-sensitive resistors and, apart from the one 15 at the centre of web 11, are connected via gating circuit 17 to an oscilloscope 18. The circuitry also includes bi-stable circuits which are operated by a squarewave generator and a diode decoding matrix so that the output of each detector can be applied in sequence to the oscilloscope whose time base is synchronized to the squarewave generator output. Detector 15 is connected to digital voltmeter 16. In operation the apparatus is calibrated to relate the voltmeter reading to the thickness of the coating and after inserting the web, the intensity of source 1 is reduced and the detector outputs checked to ensure that they are the same. The intensity of the source is returned to its normal value and deposition commenced. Variation in output showing a change in thickness may be compensated for by altering the web speed or metal evaporation rate. If a direct reading of thickness across the width of the web is required voltmeter 16 may be connected to each detector in turn. The detector circuitry may be altered so that the oscilloscope trace represents the profile of the coating or they may be used to detect only an out of tolerance condition which is recorded.

Void [Published under Sect. 91 of the Acts]. [Class 27.] Coin action, weight and multiple-coin.-A coin-receiving device for coin-freed apparatus operable by coins of different denominations comprises a balance beam provided with a counterweight and receiving the coins at points situated at such distances from the pivot of the beam that, for each price fixed, different coins, the sum of the values of which is equal to the said price, produce the same force for turning the beam and so enabling the apparatus to be operated. The beam consists of a plate 5, Figs. 1 and 2, secured to a pivot pin 4 which carries a threaded arm 12 provided with an adjustable counterweight 17. The weight 17 is adjusted according to the total value of the coins required for operating the apparatus. A block 9 with screw 30 is provided for locking beam against rotation during transportation of the apparatus. The plate 5 has conduits 31, 32 33 corresponding to the different coins used, for example, 0.25, 0.10 and 0.05 franc pieces, the bottoms of the conduits being normally closed by a plate 24 hinged at 18 to the plate 5 and held in closing position by a blade spring 28. The coins are inserted through shoots 42 and rest flatwise in a stack in the conduits. If the value required to operate the apparatus is 0À75 fr., three 0.25 fr. are inserted in conduit 31, or seven 0.10 fr. in conduit 32 together with one 0.05 fr. in condiut 33. The beam tilts under the weight of the coins until a lip. 6 thereon engages a lower stop 71. In this position a rod 25 slidable in a tube 26 on the plate 5 comes into alignment with a plunger 34, which, when depressed, causes the rod 25 to swing the closing plate 24 downwardly. The coins slide out of the conduits and down the plate 24 to a money-box. The plate 24 may also rotate a shaft and cause delivery of goods. Telephone apparatus.-In the application to telephone apparatus, when the beam is in normal position with the lip 6 against an upper stop 7, it may engage contacts to close a circuit for locking a number dial. The tilting or the beam will allow a number to be dialled, the beam in its lower position closing contacts to prevent the microphone from being used until the plunger 34 is depressed and the money cashed-in. Return of the beam to normal position frees the microphone and relocks the dial.

Title: Improvements in apparatus for distilling oils
IPC: B01D5/00
Filed: 1920-11-26
Abstract: 176,100. Robertson, T. E., (Power Specialty Co.). Nov. 26, 1920. Hydrocarbons, distilling; separate heater and evaporator apparatus.-In distilling or topping petroleum oils, the oil is heated by passage from an inlet A through tubes embedded in fire-brick blocks 4 in the roof of a furnace 2 and then through banks of tubes 3, over which the furnace gases pass. The heated oil is passed into a separator, from which the vapours pass to a condenser. Separators for the vapours may be arranged between the tubes in the furnace roof and the first bank of tubes and between the separate banks of tubes. The separators 17, Fig. 3, have vapour outlets 20 with valves 21 controlled by floats 22 so that if oil accumulates the vapour outlet is closed and the pressure will remove any obstruction in the path of the oil. The tubes are connected in vertical series in the banks so that the oil passes through all the tubes. A passage for the hot gases may be left above the banks of tubes and movable dampers be arranged between the banks to regulate the heating of each bank. The tubes in the banks are fitted at their ends with rectangular plates 8 which form the sides of the heating chamber. The projecting ends of the tubes are connected by headers 9 with cleaning-openings. The tubes are surrounded by corrugated cast-iron casings. The casings of the tubes that are acted upon by the hotter gases are formed with shallow-corrugations and have therefore lower heat-absorbing capacity.

Filed: 1970-07-13
Abstract: 1312123 Brake valves WESTINGHOUSE BREMSENUND APPARATEBAU GmbH 13 July 1970 [12 July 1969] 33831/70 Heading F2F An air brake valve for use in a three-circuit air braking system has respective inlets 1, 2, 3 and outlets 4, 5, 6 connected to actuate brake cylinders when a disc 30 is moved downwardly by a brake pedal compressing a rubber shockabsorbing member 32 and depressing a piston 24. A sealing face 29 is provided on piston 24 which firstly closes communication between an outlet duct 10 and atmosphere through a star-shaped rod 22 and immediately after opens a valve 11, 12 to connect inlet duct 9 and outlet 10 of the first circuit. Air then passes through a port 53 provided in a partition 7 causing two pistons 35, 38 to move downwardly cutting off communication between atmosphere and outlet 5 and thereafter opening valve 41, 42 and connecting inlet 2 and outlet 5. Air in this second circuit passes through a port 54 in a second partition 8 depressing a piston 46 which closes off the atmosphere connection and then opens valve 49, 50 to establish communication between inlet 3 and outlet 6 of the third circuit. If the first brake circuit fails a threaded rod 28 carried by disc 30 engages rod 22 which is carried downwardly until it abuts piston 38 and causes valve 41, 42 to open. If the second brake circuit fails, control piston 35 is charged with air from the first circuit as described previously but as no counterpressure acts on piston 35, piston 38 and a push-rod 22 move down until rod 22 actuates a push-rod 47 and thus piston 46 of the third brake circuit. The pressure build-up in chamber 10 in conjunction with compression spring 26 acts upon the lower face of piston 24 which tends to move again so as to provide an indication at the pedal of braking pressure being applied.
