Abstract: The present invention relates to tomographic or layer imaging for taking complex motion or spiral tomography images, as they are known, in medical X-Ray imaging. The insights connected with the various embodiments of the invention use structures, already present in imaging apparatus, to produce a tomographic effect by the use of vertical motion and aim to adopt such means for producing the tomographic effect that the displacement of large masses, which creates restrictions in the imaging, becomes superfluous. The different ways of realizing the tomographic motion according to this invention have the common denominator that the vertical motion of the imaging equipment is synchronized in relation to the imaging object by means other than the traditional mechanical synchronization. <IMAGE>

Abstract: 1,170,531. Colour television cameras. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 9 Jan., 1967 [8 Jan., 1966], No. 1087/67. Heading H4F. To reduce colour shifts in the red, green and blue light incident on camera tubes 4, 5 and 6 due to the differences in the reflective properties of the dichroic mirrors 2 and 3 for incident light which is polarized as a result of Brewster reflections, a thick birefringent plate 7 is included in the light path between the objective lens 1 and the light splitting dichroic mirror system 2, 3. The principal section of the birefringent plate is preferably arranged to be at an angle of 45 degrees with the plane of incidence of the dichroic mirror 2 so that the planes of polarization of the ordinary and extraordinary rays within the plate are at 45 degrees to the plane of incidence of dichroic mirrors, since the greatest differences in the reflective properties of the dichroic mirrors occur between rays polarized in the plane of incidence or normal to the plane of incidence of the dichroic mirrors.

IPC: H01H33/32
Filed: 1956-01-12
Abstract: 817,782. Fluid-pressure servomotor-control systems. BRITISH THOMSON-HOUSTON CO. Ltd. April 12, 1957 [Jan. 12, 1956], No. 1119/56. Class 135. [Also in Group XXXVII] When solenoid 4.13 is energized by an overcurrent trip circuit forming part of a traction system, valve 4.6 is raised and main control valve 4.1 is opened, so as to open arc interrupting contacts within chamber 1.1, 1.2, and apply gas blast thereto. The pressure in duct 2 is also applied to the underside of piston 6.2 whereby piston 5.1 is moved to open isolating contacts 1.7, 1.8. De-energization of the solenoid 4.13 allows the main control valve 4.1 to re-close, followed by re-closure of the interrupting contacts in the chamber 1.1, 1.2. A solenoid 7.15 is energized from a re-setting circuit, whereby valve 7 causes piston 5.2 to return the contact 1.7 into engagement with the contact 1.8, the valve 6 having been returned to its original position upon removal of gas from the duct 2. Solenoid 6.11 is energized when the vehicle passes between parts of a line conductor at different voltages. Such energization raises pistons 6.1, 6.2, so that pressure is applied to piston 5.1 to open isolating contacts 1.7, 1.8. This operation is effected without opening of the main control valve 4 whereby the contacts in the chamber 1.1, 1.2 remain closed and there is no blast discharge from outlet 1.6. After the motor connections have been suitably modified for the new line voltage, solenoid 6.11 is deenergized and solenoid 7.15 is energized to reclose the isolator contacts. Means responsive to the position of the vehicle may be provided for automatically opening and re-closing the contacts 1.7, 1.8, in the manner described. When the solenoid 4.13 is energized to open.the main control valve 4, trip lever 13.5 engages latch bar 13.3 so that the latter is moved clear of roller 13.2. If solenoid 7.15 is energized at this time, in an endeavour to change the motor connections when an over-current condition exists, then lever 7.12 pivots about its connection with rod 7.9 and the valve 7 is not operated. If the solenoid 4.13 is energized whilst the valve 7 is operative, the latch bar will again be tripped from the roller and the valve 7 will return to its non-operative position. The valves 6 and 7 may be interlocked mechanically or otherwise. Instead of interrupting the traction motor circuits, the operating current may be maintained or reduced while the isolator contacts 1.7, 1.8, are opened. The circuitbreaker may be included in the primary circuit of a main transformer for supplying the traction motors. The change to a new line voltage may be effected by opening the motor circuits on the secondary side of the main transformer. Specification 777,543, [Group XXXVII], is referred to.

Title: Process and equipment for drying ceramic pastes using microwave heating
IPC: H05B6/78
Filed: 1971-01-11
Abstract: 1339644 Drying moulded articles INTERNATIONAL STANDARD ELECTRIC CORP 11 Jan 1971 [14 Jan 1970] 1172/71 Heading F4G A wet moulded article of ceramic ware is predried (so that it can be separated from its mould and handled without damage) by maintaining the wet article throughout at a predetermined temperature (65 C.) by absorption of microwaves in the material and water of the article, while removing water by evaporation by a forced draught of dry air at a higher temperature. Batches of articles are carried on an intermittently-operated conveyer band(s) 4 relative to which a microwave enclosure 11 may be raised and lowered by means of an hydraulic jack 6a. Each batch of articles is carried on the band 4 under the raised enclosure 11 which is then lowered so that the articles occupy a highenergy microwave cavity 14 where they are heated to the predetermined temperature by the microwave sources 12. The enclosure 11 is then raised so that the articles are advanced by the band 4 into a low-energy microwave cavity 15 where they are maintained at the predetermined temperature by the microwave sources 12<SP>1</SP>. Heated dry air is supplied to the microwave cavities 14 and 15 by means of a source 9 (which may be a suction pump) supplying a main duct 22, branch ducts 19 and 19<SP>1</SP>, hoods 20 and 20<SP>1</SP>, and enclosure holes 21 and 21<SP>1</SP>. The air is extracted through enclosure holes 26 and 26<SP>1</SP>, hoods 25 and 25<SP>1</SP>, branch ducts 27 and 27<SP>1</SP>, and a main duct (not shown) by means of an extractor 9<SP>1</SP>. Shutters 24 and 24<SP>1</SP>, 28 and 28<SP>1</SP> are adjusted so that more air flows to the cavity 15 than to the cavity 14, and a slight overpressure is maintained in the enclosure 11. Each microwave source 12 or 12<SP>1</SP> comprises a magnetron coupled to a section of waveguide coupled by slots to the cavity 14 or 15. Each magnetron may be water-cooled, or air-cooled by the air supplied to the hoods 20 and 20<SP>1</SP>. A moving reflector in the waveguide continuously alters the standing wave patterns. The articles (on their moulds) are placed manually or automatically on a platform having feet raising it above the band 4, the platform being made of low dielectric losses plastics material and the enclosure and band being metal. The stainless steel band 4 may be provided with plastics projections for engaging footless platforms. The band 4 may be replaced by two spaced metal ribbons provided with projections and sliding over a fixed metal plate. Metal braid 18 on the enclosure 11 seals to the band 4 to prevent leakage of radiation. A security device prevents raising of the enclosure 11 before the magnetrons are de-energized, and a pressure-sensitive device ensures that the enclosure is fully lowered. The hoods 20 and 20<SP>1</SP> may only cover the spaces between the sources 12 and 12<SP>1</SP>. Each batch remains in each cavity 14 and 15 for 30 sec. and raising and lowering of the enclosure 11 takes 60 sec. Five or eight sources 12 or 12<SP>1</SP> may be used.

Abstract: 725,659. Thermally-actuated valves. A-P CONTROLS CORPORATION. Jan. 15, 1953, No. 1230/53. Class 135. In automatic control apparatus for a fuelflow control valve 14 having a pin 16 projecting above a casing 12 and contacting a lever actuated by a thermal element 26, 28, 32 for closing the valve with increase in temperature, the lever is a compound type having a toggle spring 54 to accelerate the pin engaging end of the lever through a critical fuel flow range independently of the thermal element. Normally, the tension spring 54, held between the actuating lever 34 contacting the thermal element and the pin-operating lever 52, pivoting in notches 48 in the sides of the channel-shaped control lever 46, holds the lever 52 against the lever 46. Thus all the levers are held in position to act as a single pin-operating lever which turns about the pivot 36 of the levers 34 and 46 when the thermal element operates the valve. The adjustable screw 56 carried by the lever 46 contacts the casing as the valve closes so that further closing movement of the lever 34 by the thermal element moves the spring past its dead centre and the lever 52 snaps the valve closed, and thus prevents, e.g., sooty operation of a burner. In a modification, the lever 46 is pivoted on the lever 34, a spring holds the levers in contact and the toggle snap-action is produced by a bow spring in compression between levers 34 and 52.'

Title: Time-bandwidth reduction system for facsimile transmission
IPC: H04N1/413
Filed: 1969-01-08
Abstract: 1,254,161. Facsimile systems. INTERNATIONAL STANDARD ELECTRIC CORP. 8 Jan., 1969 [15 Jan., 1968], No. 1236/69. Heading H4F. In a system for transmitting facsimile signals with reduced bandwidth the optical image to be transmitted is scanned on line at a time to provide a two-level signal, scanning of the next line being delayed until all the information in the previous line has been processed in a manner to be described, and transmitted. A synchronizing signal is inserted at the start of each line signal and each black signal portion is processed to be three picture elements long. The line signal is then circulated through a delay line to provide a succession of delayed one-line video signals, each having a synchronizing signal at its start. The synchronizing signal is detected in each delayed signal to start a pulse counter counting picture elements and the first occurrence of a predetermined level, as described, black, is detected to stop the counter, the pulse count being digitally encoded for transmission. The first detected black level signal is then erased before the next recirculation of the one-line signal and the next black level signal is detected, its position with respect to the synchronizing signal is encoded and it is erased as before, the process being repeated until the one-line signal contains no more black level signal elements and the scan of the next line by the camera tube is initiated. At the receiver the line and frame synchronizing signals are detected and the digital signals are decoded to provide corresponding pulse counts which are registered, a line sweep and pulse counter being started in response to each decoding operation. The receiver includes a conventional storage display tube and in response to a coincidence between the registered pulse count and the pulse counting operation the scan continues for another three picture elements and is then interrupted, the beam being blanked for two of these elements to provide "black." Thus, scanning of an " all black ' line would result in a display of a dashed line consisting of black " dashes " two elements long and white " spaces " one element long corresponding to the three element black signals transmitted. The line sweep remains stationary until the next black element position information is received and decoded at which the sweep is resumed until the next coincidence is detected and the sweep is stopped and another black element is stored. The last one-line signal of a sequence will be coded for " white " and followed by a line synchronizing pulse which resets the line sweep to its initial level, causes the frame sweep generator to advance the line sweep by one step and resets the register and counter for the reception of a further sequence of one-line digitally coded signals. It is stated that in an alternative arrangement the digital pulse count registered at the receiver may be converted into a corresponding analogue sweep voltage.
