Title: Depository machine combined with image recording means
Inventor: SIMJIAN LUTHER G
IPC: G07D11/00
Filed: 1962-11-01
Abstract: 1,002,608. Depositing documents. UNIVERSAL MATCH CORPORATION. Nov. 1, 1962, No. 41333/62. Heading G4T. A depository machine arranged to receive through a single aperture two deposit tags (Fig. 3), listing documents to be deposited, together with the documents; includes means to validate the tags, means to record an image of each of the validated tags and of the documents and means to return one tag after validation. The tags may be distinguished from the other documents by conductive edges 32 which connects a pair of roller contacts 58. Alternatively, colour codes on the tags may be sensed photo-electrically, coded apertures in the tags may be sensed, or character recognition devices may be used. In the apparatus shown, a first deposit tag 31 having a conductive edge, is fed into the machine through an aperture 12 followed by the documents to be deposited, e.g. money and checks for a bank deposit, and then finally by a second deposit tag identical to the first. Each document trips a switch 56 which causes three parallel feed belts 37 and a pair of co-operating " hold down " belts 51 to transport the document past the roller contacts 58. If the document is not a deposit tag it is dropped over a vane 76 into a channel 62 and photographed by a microfilm camera 71. The deposit tags, as they pass the roller contacts 58, connect the latter to start a timing motor. The first deposit tag is dropped into the channel 62 but before being photographed a platen 66 is lowered and a stamping head 64 raised to validate the first tag. The documents are then stacked and photographed on top of this tag as previously described. When the second tag closes the roller contacts 58 a solenoid 78 is energized to move the vane 76 to the far end of the channel against the action of a spring 82, causing the documents including the first deposit tag stacked in the channel 62 to be passed to a storage receptacle 85. The second tag then drops into the channel while the vane 76 is in the far end position and is validated and photographed, after which the solenoid 78 is de-energized and the vane 76 returns to its original position under the action of a spring 82 to cause the second deposit tag to be returned to the depositor by way of cooperating belts 37, 55 and an aperture 13. Slots for coins of different denominations leading to counting mechanisms may be provided so that coins may also be deposited, an indicator giving the total value of the coins is positioned to be photographed with the other deposits. A printing recorder may also print the value of coins entered on a record strip.

Title: Apparatus for recording and measuring the amplitudes of a plurality of time displaced electrical signal peaks
IPC: G01R13/04
Filed: 1958-12-24
Abstract: 899,535. Measuring electrically. PERKINELMER CORPORATION. Dec. 24, 1958 [Dec. 26, 1957], No. 41741/58. Class 40 (1). In apparatus in which a number of display signals are recorded successively, a reference source is applied to the recorder instead of the signals and an attenuator adjusted for each component so that the amplitude of the individual signals may be convenient. The apparatus is described with reference to drawing a " bar graph " of the various components of a process stream by a vapour chromatography method. In the apparatus shown a normal chromatogram (Fig. 1) is first plotted by connecting all the arms of the five switch banks 10-14 in position 1. In this position the output of the vapour chromatograph process (usually indicative of the change of thermal conductivity of the eluent) is applied to terminals 15 and after passing through the first switch bank has part of it tapped off at 23, passes through the last switch bank and controls the ordinate indications of a recorder. Meanwhile an auxiliary source applied to terminal 16 is connected by the third switch bank to provide a uniform abscissa drive. When the bar graph which indicates only the particular components uniformly spaced from each other is to be plotted the switch banks are set to position 4, switches 36 to 40 are then actuated successively by a cam arrangement at intervals previously determined by the times of appearance of the various components in the chromatogram of Fig. 1. As each switch closes it connects the appropriate output signal through its own particular one of attenuators 17-22 and enables it to be recorded. The cam arrangement also operates successively each of switches 29-34 which step the abscissa indication along the same amount. Thus all the various components are displayed side-by-side with equal spacing as shown in Fig. 4. Attenuators 17-24 provide an arrangement by which changes in the value of a particular component which may be of low concentration may be observed. The switches are set at position 5 which connects auxiliary source 44 to the ordinate recorder. Variable resistor 43 is adjusted to match the amplitude of a first component produced from a standard substance as recorded in the chromatogram of Fig. 1. Attenuator 17 is then adjusted to give a convenient full scale reading. This is repeated in positions 6, 7, &c. of the switch with attenuators 18, 19, &c. providing a convenient full-scale reading for each of the components so that changes in that component may readily be observed. Switches 41, 42 provide for putting a positive calibration peak and a negative " end of analysis " mark on the chromatogram. Specification 899,534 is referred to.

Abstract: 1,055,978. Cooling liquids. FUJI MANUFACTURING CO. Ltd. Oct. 23. 1963. No. 41748/63. Heading F4K. Apparatus for cooling a liquid comprises a plurality of porous tubes disposed in a path of air below a device for spraying the liquid to be cooled on to the tubes which are themselves cooled by evaporation therefrom of some of the liquid sprayed on to said tubes. In the Fig., porous tubes 1 comprising 70% of chamotte and 30% of clay are located beneath a shower device 12 and water to be cooled splashes against the tubes on its way to a sump 16 from which it is discharged through a pipe 17. A fan 7 draws air over the tube surfaces from an intake opening 6. The tubes are held in position by a frame 14 and mesh wire-netting 15 and may be arranged in diagonal or vertical and horizontal rows, or short tube lengths may be disposed in random formation (Fig. 7, not shown). Each tube 1 may have internal longitudinal ribs for increasing its internal surface area or may have diametrically opposite holes at either end for permitting water to enter the tube and pass along its interior, the holes on the lower side being smaller than those on the upper side. A finned tube 18 may be situated adjacent the intake opening 6 for heating the air and reducing its humidity; hence permitting a higher rate of water evaporation and so a greater cooling rate. The liquid to be cooled may be passed through the tube 18 as heating fluid before being passed into the spray device 12.

Filed: 1961-11-28
Abstract: <PICT:0938513/III/1> <PICT:0938513/III/2> In apparatus for removing fine material from fibre material in which fibre material is admitted to the apparatus through an air lock inlet and the fibre is discharged through an air lock outlet, p  the fibre is advanced from the inlet to the outlet by a conveyer below which is an aperture or housing forming the lower closure member of a separating chamber arranged above the conveyer and air directed upwards through the apertures blows through the fibres to carry fine material upwards into the separating chamber having a horizontal cross-section which increases from the bottom to the top of the chamber to reduce the upward air velocity to entrain the fine material and permit heavier material to settle, the air and fine material <PICT:0938513/III/3> being withdrawn through an outlet at the top of the chamber.  In the arrangement shown, fibrous material such as asbestos is fed through an air lock 31 to a screw conveyer 14 which moves the material towards an air lock outlet 32.  Air supplied by a fan 10 to a chamber 12 passes at a relatively high velocity through apertures 16 in the plate 15 below the screw conveyer 14 and through the fibrous material being conveyed by the conveyer 14 to remove dust and light fibres from the material upwardly into a separating chamber 17.  The separating chamber 17 increases in cross-sectional area from the lower end to the top end so that the velocity for the air passing therethrough decreases and in so doing deposits the heavier of the fine fibres on to inclined face 23 and members 26 to return to the conveyer 14.  The dust and air passes through a series of hinged control gates 20 into an air outlet duct 18.  An air deflector 25 may be provided on the vertical front wall 22 of the chamber 17.  A series of inspection doors 29 may also be provided in the lower portion of the air deflector 25.  If required a series of air openings 27 covered by a hinged control gate 28 may be provided below the deflector 25 to supplement the air supply in the chamber 17.  A plate, Figs. 4 and 5 (not shown), slidably mounted below the plate 15 and provided with triangular shaped apertures may regulate the air flow through the apertures 16.

Abstract: 1,272,561. Incorporating photographic ingredients into hydrophilic colloid compositions. AGFA GEVAERT. Aug. 18, 1969 [Sept. 10, 1968], No.43029/68. Heading G2C. A hydrophilic colloid composition comprising a hydrophilic colloid binder having uniformly distributed therethrough a colour coupling component and/or a mask-forming component is formed by dispersing said component(s) in the hydrophilic colloid binder in the presence of a water-insoluble wax to form a dispersion in the said colloid of wax particles containing the said component(s). The water-insoluble wax is preferably an animal, insect, vegetable, mineral or petroleum wax. The wax may be a synthetic wax selected from long-chain hydrocarbons or halogenated and partly oxidized long-chain hydrocarbons, a wax-like saturated and unbranched fatty acid or alcohol, an ester of a fatty acid and a fatty alcohol, a pentaerythritol ester of a fatty acid, an alkyl ester of 12-hydroxystearic acid, a sucrose diester of a fatty acid, an ester of fatty acid and sorbitol, a hydrogenated castor oil or sperm oil and an amide derivative of a fatty acid. A liquid solution of the said component and the said wax may be formed in a common organic solvent or mixture thereof and this solution may then be dispersed in the hydrophilic colloid binder. Alternatively an aqueous solution of said component may be formed, which is then dispersed in a solution of the said wax in a water-immiscible or sparingly water-miscible solvent or mixture thereof, the resulting liquid composition being dispersed in the hydrophilic colloid binder and the solvent(s) being removed during and/or after dispersing the liquid composition in the hydrophilic colloid binder. The hydrophilic colloid binder may be a light-sensitive silver halide colloid composition containing a disperse phase of silver halide in a hydrophilic colloid. The hydrophilic colloid composition is preferably admixed with a photographic light-sensitive silver halide colloid composition comprising a disperse phase of silver halide in a hydrophilic colloid, since this method avoids excessive agitation of the silver halide emulsion which could cause fog.

The flow-rate of a fluid through a tube is deter-, mined by measuring its cooling or heating effect on a temperature sensing probe 10 held against the tube and connected to a portable indicator unit 13 by a flexible connection 12. In an embodiment a thermocouple probe is held by a magnetic clamp against a locally pre-heated spot and signals 17 representing the temperature difference from a reference temperature are applied to a control unit together with timing signals, the rate of cooling being measured, either over a predetermined temperature drop, or over a predetermined time, and indicated at 21. The localized heating may be effected by radiant electric heater, induction heating, gas burner or propane torch. The heater may be mounted alongside the thermocouple in the probe, and energized at a standard rate during the measuring period. Alternatively, cooling instead of heating may be used, for example by a liquid spray or application of a cold mass. The heating may also be effected by causing a fluid at known temperature to flow through the tube. The method may be used for checking boiler tubes for blockages.
