Title: Process for the rapid production of screens with polychromatic divisions for color-photography
IPC: G03C7/10
Filed: 1922-12-05
Abstract: 189,813. Bercegal, R. C. M. de. Dec. 5, 1921, [Convention date]. Colour photography.-In making polychromatic screens by the method in which furrows are scratched in a previously coloured support of gelatine &c. to expose an uncoloured surface, the screen is protected by means of a soft substance such as wax, paraffin, stearin, or tallow, instead of varnish, so that after the first scratching the second colouring will only take on the freshly exposed portion. The process of applying a protective coating and colouring is repeated for a third colour. The second set of furrows may be at right-angles to the first. In carrying out the process, the film, coloured red by a colour dissolved in alcohol, is placed on a moving apron, and after a traverse of a few seconds, is treated by a water spray which drives out excess colour and a blower which dries it. The wax or other material is then spread over the surface as by a roller and the grooves are scraped by a tool with multiple microscopic teeth. The film, continuing to move, receives the green colour in alcohol which only stains the uncovered portions and is treated as before and a second set of grooves made. The blue is then applied and takes only in the grooves. Four or five colours may be applied and the screens may be mounted on glass. Specification 194/07 is referred to.

Title: Improvements in or relating to heaters for atmospheric air in buildings and the like
IPC: F24D19/04
Filed: 1956-10-31
Abstract: 857,918. Air heating apparatus; temperature responsive actuating elements. WEATHERFOLL HEATING SYSTEM Ltd., and FOWLER, L. J. Jan. 30, 1958 [Oct. 31, 1956; Aug. 1, 1957], No. 33292/56. Classes 64(2) and 64(3) In a space heater in which a stream of impelled or convected air is heated in flowing through a casing and over a heater element such as a gilled hot water tube 16 therein, a damper is disposed in the air stream to regulate the flow of air through the casing by varying an opening through which the air must pass, a thermostat having a thermostatic element operatively connected to and controlling the damper is located at the bottom of the casing, so as to be affected by the incoming air, and a normally operative regulator is provided for setting the damper to vary the effect of the thermostat as desired to permit ready alterations by the user, of the temperature in the air space surrounding the heater. In one form described two dampers one above the other are provided in the casing one damper being thermostatically actuated and the other damper being manually actuated so that the width of the air passage may be preset. The other forms described employ a single thermostatically actuated damper which may be preset by a manual adjustment. Figs. 5 and 6 show one such form in which the damper 23 is actuated by movement of a vertical rod 31 effected by a thermally sensitive element such as a bellows 27 or a differential expansion device. Movement of the rod 31 actuates a lever 55 which in turn operates a further vertical rod 56 connected to the damper 23 through a link 58. An increase, for example, in the temperature of air entering the lower end of the casing moves the damper to restrict the air flow through the casing, the initial setting of the damper being effected manually by moving the pivot point 60 of the lever 55 up or down in a slot 59 in the casing backplate using lever 61 (see Fig. 5). The thermally sensitive element shown in Figs. 5 and 6 comprises an air vessel 26 containing a bellows 27 the upper end of which is sealed to the top of the vessel and the lower end of which carries a horizontal plate 28 on which is mounted a tube 29 passing freely through an opening 30 in the top of vessel 26 and carrying the damper actuating rod 31 the position of which may be adjusted by means of locknuts 32. A further form of element shown in Fig. 7 comprises an ebonite rod 70 having one end pivoted at 71 and the other end secured to one end of a steel strip 72, the other end of the strip passing through a guide 75 to an abutment consisting of an adjustable screw 73. Changes in the temperature of the air entering the heater casing cause the free end of the element to rise or fall and thus to actuate a lever 76 pivoted at 78, which in turn operates the damper actuating rod 31.

Abstract: 1,175,783. L-Glutamic acid and orotic acid by fermentation. KYOWA HAKKO KOGYO CO Ltd. 12 July, 1968 [8 Aug., 1967], No. 33350/68. Heading C2C. [Also in Division C6] Carbon source hydrocarbon and accumulated fermentation products are recovered, at the completion of fermentation, from a fermentation liquor obtained by culturing a hydrocarbonassimilating micro-organism under aerobic conditions in an aqueous nutrient medium containing at least one hydrocarbon (specified) as the main carbon source, by adding a mineral acid (sulphuric, hydrochloric or nitric acids) to the fermentation liquor, a concentrate of the fermentation liquor or a mixture of the hydrocarbon and the micro-organism, to provide a pH of 1À0 or less, heating the mixture to at least 80‹ C., e.g. between 80‹ and 200‹ C., for at least one hour and then filtering, thereby recovering the hydrocarbon from the filtrate and purifying the liquor. According to an example, to 50 litres of the fermentation liquor obtained by culturing the 1-glutamic acid-producing strain Arthrobacter paraffineus ATCC 21167 under aerobic conditions in an aqueous nutrient medium containing n-paraffin as the main carbon source, there is added 4À35 Kg. of 35% hydrochloric acid to provide a pH of 1À0. The liquor is then heated with stirring at 100‹ C. for 5 hours and filtered and the filtrate cooled while in a stationary position. The n-paraffin is recovered from the upper phase, 1-glutamic acid from the aqueous phase. A further example relates to the treatment of a fermentation liquor obtained by culturing the orotic acid-producing strain Arthrobacter hydrocarboglutamicus ATCC 21190.

Title: Turnstile mechanism
IPC: G07C9/02
Filed: 1971-07-16
Abstract: 1387413 Turnstiles LONDON TRANSPORT EXECUTIVE G B PERCY and S HAINES 23 June 1972 [16 July 1971] 33494/71 Heading G4T In turnstiles of the type comprising a head bearing a number (e.g. three), of arms and rotatable through angular increments (e.g. 120 degrees), to bring successive arms into positions barring a passageway, the head is freed for rotation by the insertion of a coin, token or ticket or by the removal of a ticket but, instead of being automatically re-locked at the end of its first increment of rotation, may be rotated through a number of increments until a beam of radiation across the passageway is interrupted, the head then being automatically re-locked at the end of the increment of rotation in which the interruption occurred. In operation of an embodiment, a ticket passing along a shoot energizes a ticket relay (not shown), to open K7/2 and close K7/1, the latter energizing relay K8 to close K8/2 and K8/1, the latter holding K8 energized. A public transport passenger removing the ticket deenergizes the ticket relay to re-open K7/1 and re-close K7/2. A light source 3 and a turnstile release solenoid K11 are thus energized over K7/2 and K8/2. Signals from a photo-cell 4 energized by the light from 3 are amplified at 5 to energize a coil 6 which closes a switch 7, thus maintaining 3, 5, K11 and K9 energized, even when K8/2 is subsequently opened (K9 merely serves to indicate periods during which the locking mechanism is released). After 60 degrees of turnstile rotation, switches A and B are closed to energize K10 to switch over K10/1 and de-energize K8 to open K8/1 and K8/2. When the passenger interrupts the light beam, signals from 4 to 5 are cut off, so 6 is de-energized and 7 is opened to de-energize K9 and K11, the latter actuating locking mechanism, which locks the turnstile at the end of the increment of rotation during which the interruption occurred.

Abstract: 1,030,959. Wirebound boxes. STAPLING MACHINES CO. Aug. 18, 1964 [Aug. 9, 1963], No. 33774/64. Heading B5D. A wirebound box-making machine having bending means for forming a loop in the end of a binding wire attached to a box blank comprises a frame detachably connected to a vertically movable part of the machine, and a rotatable member for forming the loop carried on a support mounted on and vertically movable on the frame. The bending means is attached by an arm 40 of the frame 58 to a convenient vertically moving member of the machine supplying blanks with attached wire. On the upward movement of the machine member a tripping leg 86 strikes a fixed bar 88 and latches 76, 78 disengage so that a control bar 82 is driven down within its housing 84 by a spring 90 causing a pinion 54 to roll along a rack 56 and so rotate, by way of gears 48, 50, a spindle 42 carrying wire-bending pins 115, 116 to a position suitable for subsequently engaging and bending the wire. Downward movement of the machine member lowers the arm 40 and frame 58 and guide elements 114 attached to the spindle housing 46 straddle the wire and guide it between the bending pins 115, 116; as the arm 40 continues downwards the housing 46 becomes seated on the blank and the rack 56 drives the pinion 52 to rotate the spindle 42 and pins 115, 116 as indicated in Fig. 7 (not shown) and so loop the wire end 18. The downward movement of the frame 58 permits the latches 76, 78 to re-engage so that the whole bending means is lifted with the next upward movement of the machine member.

Title: Means for proofing or coating hollow articles such as paper or like containers
IPC: B31B1/74
Filed: 1937-12-07
Abstract: In apparatus for proofing or coating hollow articles such as paper bottles, cups or containers, and of the kind in which the containers are carried into, through and out of the proofing liquid by a guided endless chain carrier, the carrier has pivotally mounted thereon a series of container-supporting elements which are caused to move about their pivots to assume different angular positions in relation to the carrier as the containers pass through the various stages of treatment.  The containers may thus be caused to enter and to emerge from the liquid with their mouths downwards, and with tilting movements of such a nature that buckling or crumpling of the walls of the containers is avoided.  Such an apparatus is shown, comprising a heated bath 2 of paraffin wax, and an endless carrier 5 consisting of a pair of parallel chains interconnected by pivoted cross-bars. The carrier passes over sprockets 9 on a driven shaft 12, and also over sprockets 15, 18 and 20, and the pivoted crossbars are provided with arms 30, and preferably also with members 36, to engage the inside of the containers, and also with trip levers 32 to engage guides 34, 42, 45 and 48.  Guides 40 and 47, for the bottoms of the containers, are also provided, though the guide bars 47 may be replaced by a driven endless band.  The coated containers then fall through shoots 54 and are moved, by the cam-operated wall 55 on to a delivery conveyer 52. <PICT:0493896/III/1>

Abstract: 1,213,260. Data storage. LEACH CORP. 6 Nov., 1967 [7 Nov., 1966; 1 Nov., 1967], No. 34030/70. Divided out of 1,213,011. Heading G4C. Recording and playback apparatus converts input data bit levels by generating, in logic means, a level transition at bit cell centre for one bit level and no transition for the other bit level, uses the result to modulate a clock signal, records the modulated signal on a magnetic medium, reads it off, demodulates it, and converts the result to a pattern corresponding to the logic means input. Other recording and playback apparatus is disclosed but not claimed in this Specification. In Fig. 2, NRZC data 21 (upper level for 1, lower for 0) is converted to S°M form (transition at each bit cell boundary, and a mid-cell transition for each 1) using a clock (up during the second half of each bit cell) as shown then lowpass filtered 33 to get an analogue waveform which is mixed with a high-frequency bias oscillation 34 for linearization and recorded without saturation on a magnetic tape, disc or drum 30. In reading, the data is amplified 58, low-pass filtered 53, then compared 60 with itself one-bit delayed 56 (both versions limited 54, 59) to convert back to NRZC form. In comparator 60, the output of limiter 54 earths at 64, 65 one input or the other of a differential amplifier 63 receiving the output of limiter 59 at both inputs, so the comparator output is up if the limiter 54, 59 outputs are equal, and down otherwise. Phase distortion can be compensated by predistortion by inserting a tapped delay line at C in Fig. 2, the taps feeding adjustable resistors commoned to the filter 33 input, or the delay line may be replaced by a shift register with 5 stages, 2 per bit cell, a resistor being connected to one output of the centre stage and a respective variableapped resistor being connected between the true and inverse outputs of each of the remaining stages, the centre resistor and the 4 taps being commoned to the filter 33. The NRZC input data may alternatively be converted to NRZ-S form (a mid-cell transition for each 0, no other transitions) before feeding to the converter used above for NRZC to S°M conversion, by ANDing the inverse of the NRZC data with the output of a leading edge detector fed by the clock to reverse a flip-flop providing the data input to the previous converter, the clock being inverted before application to the clock input of the latter. On reading, the output of the converter used above for S°M to NRZC conversion is low-pass filtered prior to feeding two threshold detectors in parallel, the outputs of the latter being ORed to provide the NRZC data (upper level when the filter output is above a positive threshold or below a negative one). An EXCL-NOR logic circuit may replace comparator 60. Omission of the filter 33 is envisaged. References are made to parent and co-divisional Specifications 1,213,011 and 1,213,012.
