Title: Improvements in treatment of waste oil refinery sludge coke
IPC: C01B31/08
Filed: 1944-08-24
Abstract: Activated carbon is produced by heating granules of waste oil refinery sludge in a controlled oxidizing atmosphere at a temperature of substantially 850-950 DEG C. for a time sufficient to convert the granules to an adsorptive material, a predetermined amount of the granules being burned in the process.  The sludge coke may be broken down until it passes through a 20-mesh per inch screen and fed into a furnace comprising a series of shelves which are arranged so that the material is conveyed by means of rabbles to the centre and outside of alternate shelves where it drops to the shelf below.  The furnace is preferably heated by natural gas or oil and the temperature controlled by manipulation of air vents which connect with each shelf and steam jets which open on to each of the lower shelves.  The time for activation is relatively slow and it is preferred to burn away not less than 60 per cent. of the raw material.  Oxidizing gases include air, oxygen and mixtures of air and steam or air and carbon dioxide with or without steam.  The product may be used in the purification of water, edible oils, glycerine and products such as syrup, particularly corn sugar syrup for solvent recovery, gas masks and for air conditioning.  Specification 259,442, [Class 90], is referred to.

Title: Improvements in or relating to photographic printing apparatus
IPC: G03B27/30
Filed: 1961-05-04
Abstract: 940,894. Photographic copying apparatus. KODAK Ltd. (Eastman Kodak Co.). May 4, 1961, No. 16212/61. Heading G2A. A photographic processing and image-transfer apparatus comprises processing solution container having an opening through which the exposed matrix may pass, with support means adjacent said opening for supporting part of the matrix externally of the solution; a pressure roller and squeegee are secured to an arm which can move them from a non-operative to an operative position in which they exert pressure on the matrix; stop means are provided for limiting the withdrawal of the matrix from the processing solution, so that when the edge of the matrix engages the stop, the boundary between the sensitised and unsensitised portions of the matrix lies beneath the roller. The gelatin image-transfer process is that described in Specification 655, 274, and the apparatus is an improvement on that described in Specification 713, 729. The original to be copied, and the sensitised matrix, are placed together on the support 8 beneath platen 9, forming part of the printing house 7, and an exposure made. The processing solution is contained in a T-shaped tray 11 which is slidably attached to the housing 7. It has an elongated opening 15 whose bottom 16 curves upwards to end in a ramp 17. The ramp has a rightangle depression 19 ,which an L-shaped bar 21 divides into two grooves 24, 25. The top of ramp 17 is serrated, as at 27, to assist drainage. A pressure roller 36 and a squeegee 38 are mounted on arms 32 which pivot on a shaft 31 by actuation of a handle 44. When the matrix 5 has been exposed, it is separated from the original, and inserted between roller 36 (which is in the inoperative position) and ramp 17 into the processing solution in tray 11. After a predetermined development time, it is withdrawn and positioned with its leading edge 48 against a pair of stop shoulders 47, at the forward end of the apparatus. In this position, it is arranged that the emulsion coating on matrix 5 ends at the nip line where the roller 36 meets the matrix. The handle 44 is operated,to bring the pressure roller 36 and squeegee 38 into spring-urged engagement with matrix 5. A copy sheet 28 is then manually advanced from a holder 46, passing below a deflector 37, until its leading edge is in register with the separating line between the emulsion-coated portion of matrix 5 and the uncoated tab portion (i.e. the nip line referred to above). The operator grasps the leading edge 48 of the tab portion of matrix 5, and pulls it away from the tray 11, the copy sheet being drawn therewith, and as the two are pressed together between roller 36 and ramp 17, the transfer is made. The squeegee removes excess liquid from the matrix, which drains back into tray 11. Several copies may be taken in succession using the same gelatin matrix.

Title: Improvements in Embroidery Machines.
IPC: D05C11/16
Filed: 1918-10-08
Abstract: 120,206. Saurer, A., [Firm of]. Oct 20, 1917, [Convention date]. Embroidery machines.-The driving-mechanisms of different groups of implements, e.g. needles and borers &c., are controlled by an atachment to the pantograph, the particular group under control being determined by the position of the pattern-board or other adjustable part of the machine. In the construction shown in Figs. 1 and 4, the boring shafts 7, 7<1> and needle-shafts 8, 8<1> are connected in pairs by rods 9, 10 carrying rollers 11, 12 adapted to be placed in and out of gear with grooved cams 14, 15 fixed on the main shaft 13. The spindles 42, 44 of the rollers 11, 12 have a pin-and-slot connexion with pivoted levers 37, 39, one or other of which is locked by a detent 49 linked at 50, 51 to the pattern-board 5. A lever 45 pivoted on the lever 37 is linked at 46 to the lever 39 and is connected by a rod 47 to a crank 48 on the shaft of a pinion 17. The latter meshes with a sprocket 18 which is formed with a ratchet 19 and is loose on a rock-shaft 16. A sector 21, fast with the shaft 16 is oscillated from the shaft 13 by linkage 22, 23 and can be caused to transmit its movement to the wheel 18 by engagement with a pawl 24 pivoted on an arm 20 carrying a pawl 25 co-operating with the ratchet 19. The pawl 24 is held in the inoperative position shown in Fig. 1 by a detent 28 connected by wires 29 and bell-cranks 30 to a controlling-handle 32 adjacent the handle 31 of the pantograph 2. A spring-controlled disk 36 serves to hold the wheel 18 in any adjusted position by engaging pins 33 thereon. In the position shown, the needle shafts are in gear' but if the catch 28 is raised (by operating the handle 32), the sector 21 will, in its next forward oscillation, trip the pawl 24 and thus turn the wheel 18. The pinion 17 will thus be turned a half-revolution, the crank 48 reversed and, through the linkage 47, 45, 46, 39, the roller 12 withdrawn from the cam 15. If then it is desired to throw the boring-shafts 7, 7<1> into gear, the board 5 is moved to rock the link 51 which, through the rod 50, swings the detent 49 into the position shown in Fig. 4, locking the lever 39 and the needle gear against operation and freeing the lever 37. The boring-shafts can now be put into operation by means of the handle 32, the roller 11 being thrown into its cam-groove by the reversal of the crank 48 and linkage 47, 45, 37. Fig. 5 shows a detail modification in which the shaft 58 of the gear-changing crank 60 is geared to a bevel pinion 54 loose on the shaft 13. An arm 55 on the pinion carries a pawl 56 which, in the position shown, is held clear of a tappet disk 53 fast with the shaft 13 by means of a catch 57 connected to the operating-wire 29. On raising the catch 57, the pawl 56 clutches the pinion 54 to the disk 53 to reverse the crank 60. The mechanical transmission between the handle 32 and the catch 28 or 57 may be replaced by electrical or other means.

Title: Recovery of hydrogen cyanide from gases
IPC: C01C3/12
Filed: 1937-06-14
Abstract: Hydrogen cyanide is recovered in the form of alkali ferrocyanides from coal distillation gases by expelling vapours from the ammoniacal liquor recovered from the coal distillation gases, and washing these vapours with a solution of an alkali metal carbonate or hydroxide in the presence of iron or an iron salt.  The liquors obtained by cooling distillation gases or by washing them with water may be so treated.  The iron may be in the form of iron dust or iron filings. Potassium, sodium or ammonium ferrocyanide may be so obtained and in the last case there is usually sufficient ammonia present in the vapours.  The washing process may be conducted at elevated temperature, e.g. 95 DEG  C., and the vapours may be preheated. Apparatus having cast iron walls may be used.  The recovery of solid alkali cyanide from the resulting liquors may be assisted by the addition of alkali metal hydroxide and/or carbonate a liquid for re-use in the process being thereby obtained.  Specification 497,330 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 497,330.  This subject-matter does not appear in the Specification as accepted.

A resistance measuring device Fig. 1 (not shown), comprises a switchable D.C. supply connected over a series resistance to series assisting stabilizing diodes, to energize a reference resistor and an unknown resistor in series with a calibrated potentiometer therebetween; the potentiometer slider being connected to the base of a transistor whose emitter is returned through a calibrating variable resistor and whose collector is energized over a load resistor, in parallel with a Zener diode and series relay to operate at a preset voltage; the value of the unknown resistance being determined by the specific potentiometer setting necessary for relay operation. A modified resistance testing device (Fig. 2) comprises a reference resistor R 1 , in series with a variable resistor R x , which may be a shot firing circuit. Variable potentiometers are shunted across R 1 , R x  and the sliders are connected to the bases of transistors T 1 , T 2  whose emitters are returned respectively to the junction of R 1 , R 1  and the lower end of R 1 . The collector circuits each contain a resistor shunted by a relay Z 1  or Z 2  in series with a Zener diode, and the transistor bases are biased to predetermined levels set by the potentiometer sliders. It is shown that relay Z 1  will operate when R x  exceeds a critical value r 1  and that Z 2  will operate when it is in defect of a critical value r 2  to produce corresponding signal indications. The relays may be replaced by transformer coupled neon lamps. The testing device may be operatively assembled with a shot firing unit connected so that no shot may be fired if the firing circuit resistance lies outside a predetermined range of values.

Abstract: 814,261. Fluid-pressure servomotor control systems. BRISTOL CO. May 28, 1956, No. 16489/56. Class 135. A pilot valve for controlling a fluid motor e.g. a pneumatic actuator 18 of a valve, comprises a shell 20 housing a flexible diaphragm 35 which forms, with the upper part 30 of the shell, a variable-volume chamber 50 communicating through an orifice 32 with atmosphere and, through an elongated, capillary tube 34 fixed to a backing plate 33 of the diaphragm, with an inlet 16 for compressed air. The shell is externally screw-threaded to facilitate mounting in an air-block 10. A movable baffle 55 coacts with the orifice 32. A valve member 36 of hard rubber or moulded or machined plastic material is slidable on the tube 34 and biased by a spring 40 towards a seat at the bottom of the shell. Movement of the baffle 55 towards the orifice 32 increases the pressure in the chamber 50 causing the diaphragm 35, through a member 41 fixed to a spring-loaded diaphragm 44, to depress the valve member 36 and connect a chamber 49, which communicates through openings 28, an annular chamber 13, and a passage 17, with the actuator 18, whilst movement of the baffle away from the orifice causes upward movement of the diaphragm 35 to ,allow the valve member 36 to close and to withdraw the member 41 from the upper end of the valve member 36 whereby the chamber 49 is vented to atmosphere through an annular space between the member 41 and the tube 34, a chamber 51, and openings 27. The pressure applied to the actuator 18 is effective on the lower side of the diaphragm 44. In a modification, the valve member 36 has a greater clearance on the tube 34 and, is provided with a sealing diaphragm. Reference has been directed by the Comptroller to Specification 760,095.

Abstract: 666,787. Razors. BRANGE, L., and SJOSTRAND, B. E. June 22, 1949. [June 25, 1948 ; June 7, 1949] Nos. 16614/49 and 16615/49. Class 30. In a safety razor a blade is displaced in its own plane so as to be honed against upper and lower guard members, a holder for the blade having at least one extension projecting into the hollow handle of the razor and engaging a sinuous guiding surface on a driving member reciprocable longitudinally of the handle to oscillate the blade in a direction transverse to its cutting edges. As shown, the blade 2 is mounted in a holder 1 which has arms 14 extending into the handle 8. The arms are connected together by a pin 11 which engages a sinuous slot in a driving member 5 rotatably connected to a releasable cover 9. Longitudinal reciprocation of the member 5 oscillates the arms 14 round pins 6, extending outwards from the arms 14 and engaging slots in the handle, and hones the blade against guards 3, 4. In a modification in which the upper guard is pivoted to the lower guard the blade holder comprises a yoke member with down-bent ends which pass through the perforations in the razor blade and are themselves apertured for studs formed by the ends of a stainless steel wire bent to U-shape and replacing the arms 14. In a further modification the arms are connected by two pins both of which extend through the sinuous slot and are spaced apart a distance equal to an uneven number of times half a wave length of the sinuous slot.
