IPC: G03D13/00
Filed: 1970-01-23
Abstract: 1292752 Photographic processing apparatus; automatic control of temperature EASTMAN KODAK CO 23 Jan 1970 [27 Jan 1969] 3327/70 Headings G2A and G3R A latent image on a web 25 is developed by apparatus which comprises means 44, 46, 48 for advancing the web along a predetermined path and a single source of radiation 50, the web being heated in a first zone and exposed to actinic radiation through an aperture 66 in a second zone spaced downstream from the first zone. The web is cooled immediately prior to the second zone by contact with a heat sink 87. The path is formed between a drum 28 and a surrounding part-cylindrical member 26, the facing surfaces of which are coated with a low co-efficient of friction material. A resilient felt backing 58 is provided. The radiation source 50 is disposed axially within the drum, which may be internally coated at 60 with radiation absorbing material. The temperature of the heated drum is controlled by a thermistor 62 positioned on an inner surface of the drum so that if the temperature rises above a pre-set value transistor 98 is rendered fully conducting, transistor 104 is rendered less conducting and the potential across capacitor 94 is reduced to below that required to maintain diac 88 conducting. Triac 86 is then switched off to de-energize solenoid coil 82 and to close armature switch 84. A fan motor M. is thus energized to blow cooling air inside the drum.

IPC: B01D47/06
Filed: 1931-11-03
Abstract: 372,411. Washing smoke and fumes. CUTHBERTSON, J., 55, South Norwood Hill, London. Nov. 3, 1931, No. 3424. [Class 55 (ii).] In the washing of furnace gases by passing them vertically upwards through a continuous horizontal film of water, the water, after the passage of the gas, falls in the form of drops through the ascending gases. The gases from a conduit 5 enter a cleansing vessel 17 by way of a chamber 7 containing a rotary atomizer 9 which projects a mist of water into the gases to facilitate the gravitational removal of solid particles contained therein. The gases then pass through the horizontal film of water 19 which issues from a slit in a pipe 21 arranged circumferentially inside the vessel 17. The latter is also fitted with a spiral plate 25 to reduce the velocity of the gases and it serves to carry perforated trays 27 containing chalk, slaked lime or charcoal. The gases are further washed by means of steam injectors 29. In a modification of the slit pipe 21, a film of water is produced between a pair of conical surfaces and such a film may be formed at the upper end of the vessel 17, the gases first passing through a perforated cone 31. Specifications 4621/10, 165,451, [both in Class 55 (ii), Gas manufacture &c.], and 268,467, [Class 81 (i), Disinfecting &c.], are referred to.

Title: Improvements in or relating to registering and recording devices for weighing apparatus
IPC: G01G23/18
Filed: 1934-02-02
Abstract: 421,022. Weighing-apparatus. FITZPATRICK, H. D., 94, Hope Street, Glasgow.- (Maatschappij van Berkel's Patent Naamlooze Vennootschap; 33, Boezemsingel, Rotterdam, Holland) Feb. 2, 1934, No. 3460. [Class 143] [See also Group XXXVIII] Printed records, apparatus for giving.-Relates to a registering and recording device for weighing-apparatus of the kind in which a weight indicator (or other moving part of the weighing mechanism) and a recorder, relatively movable, are provided with co-operating electric contacts constituting a detector, the function of which is to stop the recorder for the performance of the recording operation. The invention consists in initiating the stoppage of the recorder by closure of a switch in an electric control circuit whereby the co-operating electric contacts receive relative displacement into the same path of movement so that they make contact, the return displacement of the contacts into separate paths being permitted by the opening of the switch. The spindle of the indicating pointer 1 carries an auxiliary pointer 3 and these automatically assume a position dependent on the weight of the commodity on the scale pan. A printing rim 6 guided by rollers 8 carries an electromagnet 9 and is adapted to be driven by an electromotor 7. After placing the commodity on the scale pan the motor is automatically or independently started and rotates the printing rim 6. A switch 11 is closed by hand to complete a circuit through the electromagnet 9 which then moves a contact 10<a> into the path of a contact 3<a> on the auxiliary arm 3. When the rim has rotated sufficiently, the contacts 3<a>, 10<a> meet and an electromagnet 23 is energized to release a holding catch 15 thus permitting a spring 25 to slide a clamping plunger 16 into locking engagement with the rim 6. Simultaneously, a spring-actuated printing hammer 17 interconnected with the clamping plunger is liberated to obtain a record of the weight and /or money value by pressing a paper strip or chart 18 against the type on the rim. The printing movement of the hammer opens a switch 19 and stops the motor. The operator now releases the switch 11 and re-sets the holding catch 15 by means of a handle 20, thus unlocking the printing rim and re-starting the motor in its forward direction until the switch 11 is again closed to effect a further recording operation. A transformer 21 steps down the voltage of the current through the electromagnet 23, and a rectifier 22 reduces the voltage in the circuit of the electromagnet 9.

Title: Improvements in or relating to television amplifying circuits
IPC: H04N5/205
Filed: 1964-08-18
Abstract: 1,076,997. Television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 18, 1964 [Aug. 21, 1963], No. 3556/67. Divided out of 1,076,996. Heading H4F. A video amplifier T 1  has a collector load circuit including capacitance C c  and a diode D 2  which has a non-linear current-voltage characteristic, whereby at low signal levels corresponding to dark portions of an image the diode internal resistance is high and the amplifier bandwidth is small, and at high signal levels corresponding to light portions of the image the diode internal resistance is low and the bandwidth is large. The invention, which is particularly applicable to camera channels, is intended to reduce the effect of noise which is most apparent in dark portions of the image and is based on the assumption that noise is proportional to a function (the square root) of bandwidth. The variation of the diode resistance also brings about a variation of amplifier gain, such that the collector gain falls with increase of frequency, and this is offset by an emitter circuit R e , C e  which provides degenerative feedback which decreases with increase of frequency. The variation of diode resistance may also be utilized to introduce gamma correction. The characteristic of the collector circuit is made adjustable by the inclusion of a variable resistor 6 in series with diode D 2 . The video signal is applied to the base of transistor T 1  from an emitter follower stage T 2  and has the D.C. component established by a switched clamp stage T 3 . Thermionic tubes may replace the transistors.

In one embodiment (Fig. 2) the secondary vessel, which is of prestressed concrete, encloses the entire primary vessel (which may be of concrete or steel) and other equipment such as boilers 15. A refuelling machine 21 is disposed entirely within the space 18 between the vessels. In general, the arrangement permits on-load remote refuelling. The interior of the secondary vessel is filled with air or nitrogen; during refuelling, at reduced reactor load, the primary pressure is reduced to approximately the pressure in the secondary vessel. A pressure relief system ensures that the pressure difference between vessels does not exceed vessel design criteria. In another embodiment (Figs. 3 and 4, not shown), part of the refuelling machine 21 is external to the secondary vessel which has a top cap constituted by mutually eccentric circular shields (23, 24) rotation of which allows the machine to cover the complete array of fuelling nozzles 20. In a further embodiment (Figs. 5 and 6, not shown) gas turbines extract thermal energy from the coolant. In yet a further embodiment (Fig. 7, not shown) the thermal energy extraction apparatus is housed in pods (36) in the wall of the primary vessel. An annular store (38) for new and/or irradiated fuel is accommodated in the space 18 between the vessels. The energy extraction apparatus may comprise boilers &c. as in the Fig. 2 embodiment, or turbogenerator units as in the embodiment of Figs. 5 and 6. In the embodiment shown in Fig. 8, the secondary vessel does not completely surround the primary vessel 11 but is constituted merely by extensions 40 of the primary vessel sidewalls, and a top cover 41. The thermal energy extraction apparatus is disposed in pods 26 in the primary vessel walls, the pods having sealing covers 42. (In previous embodiments, with or without pods, such apparatus has been sealed in enclosing containment means.) The pods 36 may be steel-lined. In general, the secondary vessel can withstand the pressure within it which would result from failure of the primary vessel. Where boilers 15 are used, these may be positioned to cause a thermal syphoning effect to assist the forced coolant circulation.
