Title: Improvements in or relating to the production of gas
IPC: C10J3/46
Filed: 1950-03-14
Abstract: 688,915. Gasifying solid or liquid fuels. ENTREPRISE GENERALE DE CHAUFFAGE INDUSTRIEL PILLARD FRERES & CIE. March 14, 1950 [March 14, 1949], No. 6415/50. Classes 55 (i) and 55 (ii) [Also in Group XXX] Powdered or liquid fuels are gasified in an elongated reaction vessel comprising zones 8, 24 and 25 in admixture with a gas containing free oxygen and steam, the mixture being introduced into the zone 8 under a pressure of 20-25 kilogrammes per sq. cm. and the resulting gases progressively cooled as they pass up the vessel through zones 24 and 25, the crosssectional area of the zone 25 being greater than that of the zone 8 to give a residence time of the gases in that zone of about 30 secs. and allow formation of methane. The reaction vessel comprises an inner shell 6 lined with refractory material 7 at its lower end and an outer shell 4, the space between the shells 4 and 6 forming a water jacket which cools the gases. The fuel is injected into the zone 8 through a series of nozzles 27 by means of steam, preferably superheated, from a boiler 32a and oxygen is admitted from a line 49 through the concentric nozzles 28, the arrangement being such that the injected substances are violently agitated and almost complete gasification is effected in the zone 8. All the steam for the process may be supplied to the zone 8 but steam may also be admitted through pipes 62 to control the temperature in the zone 25, the temperature of the gases leaving the zone 8 at 1000‹- 1200‹C being reduced to about 300‹C at the gas outlet 26. The fuel-steam mixture charged into the zone 8 may be supplied by apparatus (see Group XXX) comprising a hopper 37 and an ejector 33 which is arranged in the line 30 connecting the boiler 32a with the nozzles 27. The supply of oxygen may be regulated automatically to the flow of steam in the line 30 by utilizing the pressure drop across an orifice 51 arranged in the line 30 to actuate a control valve in the oxygen supply line 49. The base of the gasification zone 8 has an outlet 9 to allow discharge of any ash not entrained in the gases produced. The unpurified gases obtained may have a composition of CO 2  20-25 per cent, CO 16-18 per cent, H 2  20-22 per cent, CH 4  20-22 per cent and inerts 15-20 per cent. The CO 2  content is reduced by any suitable means to less than 5 per cent.

Title: Improvements in racket string
IPC: A63B51/02
Filed: 1937-03-06
Abstract: 474,134. Racket strings. UNITED STATES RUBBER PRODUCTS, Inc. March 6, 1937, No. 6669. Convention date, March 7, 1936. Drawings to Specification. [Class 109] A resilient racket string comprises a rubber core and a tightly braided outer cover which holds the core extended longitudinally and compressed circumferentially. The pressure imparts to the string a contractive force in excess of the strength of the core. An intermediate textile cover or two oppositely wound covers may be wrapped round the core. Before or during the braiding operation the covered core may be treated with adhesive containing animal glue, glycerine and castor oil. After the braid is applied and before the adhesive binder sets, the string is preferably stretched under high tension and dried in this condition. The string may be repeatedly wetted and dried under tension to stretch it to approximately the limit of elongation. It is then treated with a flexible waterproofing material, such as lacquer.

Title: Separating means
IPC: B07C5/342
Filed: 1973-02-12
Abstract: 1449021 Separating solid materials LOCKWOOD GRADERS (UK) Ltd 23 Jan 1974 [12 Feb 1973] 6708/73 Heading B2H A device for separating wanted and unwanted items comprises deflector means normally extending into the path of a moving mixture of the items, and control means adapted to retain the deflector means in the path of a wanted item, whereby to deflect said item in a pre-arranged direction for collection, but to leave the deflector means free for displacement by an unwanted item, whereby the unwanted item continues to advance, substantially without diversion, for disposal or discard. The device may be used for sorting potatoes I from stones 2 etc in a mixture thereof. The mixture is allowed to fall from a conveyor 3 on to a row of deflectors 6, 7 arranged side by side and pivotable on a common rod 4. Each deflector consists of arms 6, 7 at an angle to each other. The arm 7 is connected by a link 8 to the core of a solenoid 9 and is so weighted that it normally rests against a stop 10 whereby the arm 6 is located in the path of the falling mixture. The arm 6 may be locked in this position by engagement of arm 7 by means of an arm 15 of a spring biased lever 13 swing- able about a pivot 14 by means of a solenoid 18. Above the row of deflectors and adjacent to the path of fall of the mixture are located a corresponding number of radiation-sensitive detectors 19. When actuated by radiation received from, or interrupted by, a wanted potato, a detector 19 transmits a signal to one or more relays closing the circuits of solenoids 9 and 18. Solenoid 9 steadies the arm 7 against its stop 10 and solenoid 18 rocks its lever 13 to move its arm 15 over the arm 7 so as to lock the arm 6 in the path of the desired falling potato to deflect the latter to,a collecting bin. The solenoids are then immediately released to free the arm 6 and allow it to be displaced in the dotted line position by a falling unwanted stone etc. which continues substantially along its path and is collected in a separate bin. After being so displaced the deflector tends, on account of its weight bias, to return to the position in which arm 7 rests on stop 10, this return being expedited by a continuously rotating cam 11. The solenoids 28 may be connected in circuit in pairs, Fig. 2 (not shown), so that the arms 6 may be locked in adjacent pairs when a signal is transmitted to any one. In a modification, the deflector locking means 13-18 may be omitted and replaced by an electromagnet located beneath the free end of the deflector arm 7 to which a metal insert is fitted.

IPC: B03B5/38
Filed: 1955-03-08
Abstract: 809,955. Washing granular materials. SIMON-CARVES Ltd. Feb. 14, 1956 [March 8. 1955; Sept. 5, 1955], Nos. 6758/55 and 25387/55. Class 82(2) In a sink and float process and apparatus for separating solid materials employing liquid suspensions of different density, raw material is fed at 32 together with liquid suspension 13 into a bath 1 of the liquid suspension wherein a primary separation occurs, floats and some suspension being removed at 11, 34; suspension of a greater density than that in bath 1 is introduced to the bottom 10(7) of the separator whereby the sinks from bath 1 undergo a further separation, the floats from which (the middlings) are carried up the arm 4 by the suspension of intermediate density for discharge with the said suspension at 15, 33; while the secondary sinks are withdrawn from the bottom of the separator, e.g. by an elevator 8 for discharge at 9. Fig. 2 shows the separator and medium recovery circuit with cyclone thickener 31. The suspension source is vessel 28 whence it is raised via pump 29 to thickener 31. High density suspension from the thickener passes to vessel 35 and thence via valve 6 to entrance 7 (and 10 if desired) of the arm 5 of the separator; any overflow goes to vessel 61 where it meets the low density suspension from 31 which travels via rubber tube 63 and one side 65 of a splitter box. Tube 63 is governed by a lever 66 controlled either manually, or automatically according to the specific gravity of the suspension in vessel 35, to keep a predetermined density; liquid from the part 64 of the splitter box is led to vessel 35. Low density suspension leaves vessel 61 via control valve 68 to the inlet 13 of the separator; overflow passes by pipe 23 to the vessel 28. If desired, the suspension may be pumped direct to the separator (at 13) from the source 28 if the normally open valve 69 is closed and the normally closed valve 24 is opened. Suspension from exits 34, 33 of the separator is led to the source 28 direct. The products of the separation are washed with water at screens 37, 70, 71, the wash waters being led to screen 40 which removes fine material and then pumped to desliming case 43 for magnetic separation. The magnetized material falls to the bottom of case 43 whence it is raised by pump 46 to demagnetizer 47 and splitter box 49 governed by lever 50 controlled by the specific gravity of the medium in the lower part of 43. Part of the medium is returned from the splitter box to case 43, and part via pipe 51 to vessel 28, depending upon the position of lever 50. Overflow from 43 which is substantially medium-free water may be led to washing screens 37, 70, 71 via pipes 55, 56; while clean water is admitted to the separator at 53, being controlled by valve 54 according to the specific gravity of the bath in the separator. Magnetized material may if desired be led via valve 57 to the vessel 28

Abstract: 1299782 Multiplexing television and facsimile or like signals MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 13 Feb 1970 [16 Feb 1969 14 Oct 1969 6 Dec 1969 (2)] 7111/70 Headings H4F and H4L In a system for transmitting facsimile or like signals in binary code on the sound carrier wave of a conventional television system, a subcarrier is frequency-modulated by the binary code and the modulated subcarrier modulates the sound carrier wave. In one arrangement letters, numerals, &c. are transmitted by a six-digit binary code each digit being represented by the presence or absence of a different audiofrequency, two further digits similarly represented indicating upper or lower case and providing a gate signal respectively, and the frequencies being transmitted in succession. At the receiver. Fig. 4 (not shown), the subcarrier signal is selected at the output of the frequency discriminator for the sound signal, demodulated and the various audio-frequency signals selected by filters. The output of the filters are rectified, limited and differentiated to trigger monostable devices coupled to a matrix converting the binary code to decimal or letters of the alphabet which are reproduced by a typewriter. A picture may be reproduced by transmitting a single frequency whose presence or absence indicates a black or white spot respectively, these spots being transmitted in groups separated by a further frequency to represent horizontal rows. By the use of an additional subcarrier further signals may be transmitted. In a further arrangement the subcarrier is arranged to be twice the horizontal repetition frequency of the television signal, one digit is transmitted in each horizontal repetition frequency period and fifteen of such periods are used for each letter. At the receiver the horizontal sync. signals are used to derive a signal to define the start and finish of a code letter for reproduction by a printing device. The vertical scanning signals of the television receiver may be used to control the horizontal deflection of a beam in a cathoderay tube of an electronic printer, Fig. 17 (not shown), and at the end of each row to control the operation of a magnetic clutch co-operating with a motor driving a reel of printing paper. Alternatively, synchronizing signals may be transmitted by modulating the subcarrier.
