Abstract: 1,139,757. Embossing surfaces. KLEINEWEFERS GRAVUREN G.m.b.H. 6 May, 1966 [28 May, 1965], No. 20047/66. Heading B6C. A jacket for an embossing roller is produced from the relief surface of a laminar original by wrapping the original about an auxiliary cylinder with the relief surface facing inwards and with the edges abutting, eliminating the appearance of a seam at the edges, disposing the auxiliary cylinder and original inside a working cylinder, attaching the outer surface of the original to the inner surface of the working cylinder with adhesive, withdrawing the auxiliary cylinder and preparing by means of electrodeposition or a fluid casting material, e.g. epoxy resin, a negative relief image of the relief surface of the original, this image constituting the jacket. The jacket may be a direct negative relief image of the inner surface of the original. Alternatively a first negative relief image may be prepared from the inner surface of the original by casting, e.g. with a polysiloxane rubber, a positive relief image prepared from the negative image by casting, e.g. with an epoxy resin, and the jacket prepared from the positive image by electrodeposition or by fluid casting.

Title: Improvements in and relating to drying materials in crumb form
IPC: F26B3/00
Filed: 1960-06-08
Abstract: 884,089. Drying materials in crumb form. BLAW-KNOX CO. June 8, 1960 [June 10, 1959], No. 20110/60. Class 34(2) In a process for drying materials in crumb form, e.g. emulsion polymer crumbs, liquid is expressed from the crumbs in a compression zone under conditions producing a substantial increase in the temperature of the crumbs, drawing off the expressed liquid, extruding the heated crumbs into a decompression zone, comminuting the material as it passes into the decompression zone and maintaining both a temperature and a vacuum in the decompression zone sufficiently high to cause retained liquid to vaporize. Apparatus for carrying out the process comprises expressing liquid from the crumbs by an extruder 2, the screw 3 of which performs mechanical work on the crumbs to substantially increase their temperature, removing the expressed liquid through a drain 11c, extruding the heated crumbs into a decompression zone 5 wherein a vacuum is maintained to vaporize the remaining liquid in the crumb and wherein the crumb is comminuted, and the dried crumb proceeds to a second extruder 6 for extruding the consolidated product through an extrusion head 10. The extruder 2 has sections 11, 12, the former comprising cylindrical and tapered chambers 11a, 11b respectively to compress the crumb and to enable the screw 3 to raise the crumb temperature. The section 12 has a heating jacket 13 to heat the crumb prior to passing to a rotary disc valve 16 operated by a handle 17 and having apertures 16a which register with apertures 18a in a parallel stationary plate 18 to control the back pressure within the extruder 2. The crumb passes through a passageway 19 in the main wall 21 of the decompression zone 5 where it is severed and comminuted by a helical knife 33 formed as flights on a shaft 28 driven by a motor 30. The zone 5 has means 24 communicating with a vacuum pump (not shown) by which air and vaporized moisture is withdrawn from the zone and the zone also has a heating jacket 22 to maintain the temperature of the crumb. The comminuted product is downwardly urged by gravity and the helical knife past a combined observation glass and dwell stage 36 into the extruder 6.

Title: Improvements in animal traps
IPC: A01M23/30
Filed: 1923-08-09
Abstract: 222,272. Marks, E. C. R., (Snappy Manufacturing Co. of Canada, Ltd.). Aug. 9, 1923. Animal traps.-In a break-back trap the catch rod 17 restraining the usual break-back frame 13 is engaged under an horizontal lip 25 integral with an upstanding plate 22 attached to the baitlever 19 of light metal strip. A portion 21 of this bait-lever is slit and depressed so that the bait-lever pivots loosely thereby on the spindle 12 in all directions, and particularly transversely. Any such transverse movement of the bait-lever bv the animal causes one or other of the edges 23, 24 of the upstanding plate 22 to lever the catch-rod from under the lip 25 and to spring the trap, whilst any up and down motion of the baitlever causes one or other of the curved edges 26, 27 of the lip 25 to lever the catch-rod free. In a modification, Figs. 8 and 13, a slot 56 in the upstanding plate on the bait-lever 19 coacts with a sinuous end 67 of the catch-rod. If the baitlever is disturbed transversely or vertically one of the vertical ends of the upstanding plate or the upper edge of the slot 56 respectively levers the end 67 out of the slot to free the catch-rod.

Title: An improved process for the separation of hydrocarbons
Inventor: MARCHANT ALAN
IPC: C07C7/17
Filed: 1959-06-15
Abstract: In the separation of acyclic conjugated diolefins from hydrocarbon mixtures by reaction with sulphur dioxide to form a sulphone, the unreacted hydrocarbon is separated as a liquid from the sulphone which latter is decomposed to recover the diolefin. The reaction with sulphur dioxide is effected in the liquid phase at 60-80 DEG C. and up to 1,000 p.s.i.g. with a molar ratio of sulphur dioxide to diolefin between 1 : 1 and 8 : 1.  The dimerisation of cyclic dienes is preferably effected simultaneously.  The process may be continuous, the reactants being continuously introduced into a reactor from which hydrocarbons are recovered at the top and sulphones at the bottom.  A polymerization inhibitor, e.g. an alkyl phenol may be present.  The sulphone is decomposed by distillation at atmospheric pressure and dissolving the sulphur dioxide in an aqueous liquid.

Abstract: 1465534 Automatic exchange systems; analogue gating circuit MITEL CANADA Ltd 9 May 1974 [26 June 1973] 20480/74 Headings H4K H3T and H4R In a hotel telephone system, amplifiers having both an A.C. and a D.C. threshold level are connected by their inputs across the telephone lines of respective subscriber sets and each feed a respective electro-acoustic transducer, the D.C. threshold level of the amplifiers being such that each amplifier is only operative when the respective telephone line is not looped. The amplifiers A 1 -A n  are used to supply amplified ringing tone, "message" tones and public address announcements or music emanating from respective signal sources 52, 38, 58 at a central station. To reduce the voltage levels of these relatively high frequency signals to a minimum to reduce crosstalk each signal is added to a low frequency pilot signal from a source 30 at respective adders 40, 26, 56, the combined amplitude of the signals exceeding the amplifier A.C. threshold level. Alternatively the pilot signal level itself may exceed the A.C. threshold of the amplifiers so as to prevent the amplifiers switching on and off during silient periods of the supplied signal. The crosspoint network for connecting the combined signals to the telephone lines may use relay or solid state crosspoints. The amplifier (Fig. 2) has its D.C. threshold set by Zener diode Z D  such that the Zener diode will not conduct with the line A J , A R  looped. With the D.C. threshold exceeded incoming A.C. signals are fed via Zener diode Z D  to the base of transistor Q 1  of a differential amplier and to a rectifying circuit comprising transistor Q 4  resistors 96, 98 and capacitor 102. Only with a predetermined A.C. signal level is the output of the rectifier circuit sufficient to turn on transistor Q 3  to render the differential amplifier operative. The capacitor 118 is chosen so as to have a high impedance at low frequencies such that the pilot signal produces substantially the same input at both transistors Q 1 , Q 2  and is therefore effectively removed from the amplified signal.

Abstract: 233,217. Stromberg Motor Devices Co., and Mock, F. C. Jan. 31, 1924. Spray carburettors.-The idling or by-pass nozzle orifice is adjustable, being mounted eccentrically in a rotatable plug provided with an extension carrying an arm having a spring detent adapted to engage recesses in a fixed plate over which the arm moves. Fuel is fed to the idling nozzle through ducts and an annular space at the base of the main nozzle and through a calibrated plug at the lower end of a tube surrounded by a space to which air is admitted through bores in an interchangeable off-set plug. The carburettor casing comprises a lower part 23 and an upper part 24 joining along the line 25 which is above the normal fuel level x-x. Two carburetting chambers 27 extend through the casing, each chamber having a throttle valve 31, a main nozzle 29 and a Venturi tube 28. The main nozzle has discharge orifices 87. Fig. 4, in a conical head 88 at the base of which is a narrow flange 86 which prevents fuel from being drawn into the eddy space above the nozzle as an accumulation of drops as described in Specification 233,216. From the float chamber fuel passes to each of the nozzles through separate ducts 61, Fig. 2, leading to bores 62 each containing a plug 64 with a restricted orifice 66 and then to a chamber 67, Figs. 2 and 4, at the base of the main nozzle which is supported on the arms 72 across the air inlet. A plug 69, Figs. 2 and 4, in a chamber 67 is bored at 82, 83 and screws into an upper part 71 over which is again screwed a part 75 so as to leave a well 76 which communicates through an extension 78, 79 and apertured plug 81 with the carburettor air inlet. Air reaches the fuel stream through apertures 77. The ducts 83 in the plug 69 open into an annular space which communicates through a passage 85, Fig. 2, and calibrated orifice 91 with the idling nozzle 109 which is fed with aerated fuel through a tube 92 and passage 102, the tube 92 being surrounded by a chamber 93 to which air is admitted through a calibrated axial bore 97 and lateral bores in an interchangeable off-set plug 94, Figs. 2 and 3. This air is taken from an annular space 96 around the Venturi tubes, which space is in communication through ports 98, Fig. 1, with a lower annular space 99 opening into the air intake through a slot 101. The idling nozzle 109 is eccentrically mounted in a rotatable plug 104, Figs. 1 and 5, so that by adjustment of the plug the nozzle may be caused to discharge above, below or at the edge of the throttle, when in the closed position. The plug has an extension 111 carrying an actuating arm 112 provided with a spring detent 114 adapted to engage recesses 115 in a quadrant 113, Fig. 6. A lateral bore 103, Fig. 5, in the plug connects the nozzle 109 with the fuel passage 102. In a modified construction, the passages 83 are dispensed with, the plug 64 with its restricted orifice 66 being arranged at the base of the main nozzle directly above the plug 68.

Title: Oxygen analyzer
IPC: G01N27/49
Filed: 1964-05-19
Abstract: 1,057,753. Determining oxygen content of gases. I. M. CLARKE (G. Bergson and P. Ketelsen). May 19, 1964, No. 20654/64. Heading G1N. In the quantitative analysis of oxygen in a flowing gas stream, gas under pressure is passed from pipe (10), Fig. 1 (not shown), through a wetter cell (18), via a pipe (22) to a trap (24), then through pipe 26 to an electrolytic oxygen analyzer cell 28 (Fig. 4), and thence through a neutralizer cell (42) containing a material which is chemically reactive with the analyzer electrolyte and removes from the gas electrolyte entrained therein in molecular form before the gas is passed via control valves (44), (46) and a flow meter (48) to an outlet (12). Analyzer Cell. Fig. 4 and Fig. 5 (not shown). The cell 28 comprises a transparent plastics casing 84 containing a solution of potassium hydroxide KOH, a gas inlet 90 and an outlet through a porous filter 124 which removes electrolyte picked up by the gas stream in mist form, a porous silver cathode 86 and three anodes 98, 108, 118. The anode 98 comprises a loop of cadmium strip, the anode 108 is of cadmium strip and the anode 118 is of stainless steel. Electrical Circuit (Fig. 6), and Operation. The first anode 98 establishes the relative potential of the electrolyte which is considered as a reference. The anode 108 is at - 0À75 Volts and anode 118 is at + 0À75 Volts while the cathode 86 is at - 0À65 Volts, and the dissociation potential of water (approx 1À7 Volts) is never reached. Oxygen bubbled in contact with cathode 86 and the electrolyte produces negative hydroxyl ions requiring electrons from the cathode 86. These ions are removed from the cathode vicinity by the gas and the excess solution negative ions are removed by the re-establishment of equilibrium due to hydroxyl ions reaction at the anode 118 with simultaneous release of electrons and oxygen. The electron current flow between the cathode and anode 118 is a function of the amount of oxygen in the gas stream. This current passes through a resistor 144 and meter shunts and its magnitude determines the input level to an amplifier 150 and the reading on a meter 148. Impurities in the anodes produce +ve ions and to prevent these collecting on the first anode 98 and cathode 86 the second anode 108 is at the most negative potential. The neutralizer cell may have a transparent casing and contain aluminium pellets. The construction of the wetter cell is described, Figs. 2, 3 (not shown). Its purpose is to wet the gas so that it will not absorb moisture from the electrolyte.
