Title: Improvements in and relating to distributors for hydraulically controlled injectors in liquid fuel injection systems for internal combustion engines
IPC: F02D1/00
Filed: 1937-05-01
Abstract: 494,953. Valve mechanism; regulating. ATTWOOD DIESEL EQUIPMENT CO., Ltd., GORDON, H., and ATTWOOD, S. H. May 1, 1937, No. 12502. [Class 7 (vi)] Means for distributing liquid fuel to injectors on the engine cylinders comprise several slide valves 3 controlling conduits leading to the injection valves and operated in sequence by two cams engaging a tappet and adjustable for varying the time of commencement and the duration of the injection. The cam gear comprises a radially-movable tappet 35 which is rotated around a pair of fixed cams 23, 24, arranged side-by-side, the cams co-operating with laterally displaced shoulders 37, 38 formed at opposite ends of a rocking member 36 mounted in the tappet, the arrangement being such that, when only one cam is in contact with the rocking member, it rotates in the tappet without moving the latter radially, but when both cams come into action together on the opposite ends of the rocking member, the tappet is moved radially to actuate the distributing-valve which it is passing at that period. Thus, by angularly adjusting the cams relatively to each other, the duration of injection is varied, whereas by advancing or retarding both cams the time of commencement is varied. Axially adjustable helical gear is described for effecting the former adjustment, while the latter adjustment may be obtained by means of a cam plate actuated by a speed governor as described in Specification 494,954, [Group XXIX]. In a modification, a grooved form of cam device is used which actuates the distributing-valves positively in both directions. The apparatus may be used in connection with the fuel-injection system described in Specification 494,955. Specification 494,951 also is referred to.

Title: Cyclical process for the manufacture of titanium dioxide pigments
IPC: C22B1/08
Filed: 1943-08-03
Abstract: 574,818. Treating iron-bearing titanium ores. BRITISH TITAN PRODUCTS CO., Ltd. Aug. 3, 1943, No. 12506. Convention date, Aug. 1, 1942. Drawings to Specification. [Class 1 (iii)] [Also in Group XXXVI] Iron-bearing titanium ores such as ilmenite are treated with hydrochloric acid to bring the bulk of the iron into solution and leave a titanium dioxide concentrate, the latter is chlorinated to form and volatilise titanium tetrachloride, which is brought into solution and hydrolized to obtain hydrated titanium oxide which is calcined and hydrochloric acid for treating fresh ore; whilst the iron chloride solution is reduced and electrolysed to obtain metallic iron and chlorine which is used for chlorinating fresh titanium dioxide concentrate. In the first step elevated temperatures and relatively concentrated hydrochloric acid are used. In the chlorination step, the concentrate is preferably briquetted with carbonaceous material and a binder and ferric chloride passing off with the titanium tetrachloride is separated therefrom and added to the iron chloride solution to be electrolysed. The latter is usually acid and is neutralized before or during the reduction of ferric chloride present to ferrous chloride. Spent electrolyte from the electrolysis step may be used to form the titanium tetrachloride solution, and hydrolysis of the latter be effected in the presence of nuclei. Electrolysis may take place in a diaphragm cell having a carbon anode and iron cathode, using the iron chloride solution as catholyte and calcium chloride solution as anolyte, and current densities of 2-10 amps. per sq. decimetre. Specification 421,308 is referred to.

Title: Improvements in sound recording and reproducing apparatus
IPC: G11B3/20
Filed: 1944-06-30
Abstract: 580,698. Sound recording and reproduction. DAVIES, H.. June 30, 1944, No. 12525. [Class 40 (ii)] In a machine for recording on or reproducing from disc records, the transducer is pivoted so as to swing normal to the record on a carriage 4 which is supported on and traversed along two rods 2, 3 of which the spacing may be adjusted to vary the inclination of the cutter or stylus to the record surface. In the arrangement described, rod 2 is fixed and rod 3 rotatable in eccentric bearings by a hand-operated control. The carriage 4 is mounted at one end to rock about the arcnate surface of a sleeve 9 on shaft 2 to accommodate slight non-parallelism between the rods 2, 3, and is supported at its other end by links 13 ,pivoted on rod 3. The cutter or reproducing head 15 is pivotally mounted at 16 in a traversing head 17 which is fixed on one end of a hollow spindle 18 which extends through the horizontal .portion 5 of the carriage 4, the head 17 and shaft 18 being held in position by spring 23 surrounding the shaft. The traversing head is normally latched in the recording position ,shown, but the latch may be released by operating a push-button (Fig. 3, not shown) to enable the head to be rotated by a spring 21 acting on arm 19 rigid with the shaft to bring the cutter head to a position to allow a record or a blank to be placed on the turntable 59. The traversing head may be further rotated by ,hand and latched in position to permit easy access to the cutter 28. With the traversing head in recording or playing position, the cutting or reproducing head may be raised off the surface of the record by rotation of an eccentric bar 32 which engages bell-crank lever 31 from which movement is transferred via push-rod 30 extending axially of shaft 18 to lever 29 which engages the cutter-arm. The landing position of the cutter is determined in accordance with the size of the record by setting manually the appropriate stop 48 for limiting the travel of 'carriage 4 which carries a pin 51 for engaging the stop. The pin is urged upwardly by a spring 52 supported on a pivoted platform 53 which is free to drop when the half-nut 34 is brought 'into engagement with feed-screw 33 for traversing the carriage, thus allowing pin 51 to drop to clear any depressed pin 48 when traversing movement of the carriage begins. The pins 48 are yieldingly mounted and bevelled at their ends to allow return movement of the carriage. The half-nut 34 is slidably mounted on a pin (not shown) in a cradle 35 so as to be free to slide to engage snugly on the feed-screw when applied thereto, the movement of the nut being made against friction applied by a spring 43. Cradle 35 is pivoted at 38 and is raised and lowered to move half-nut 34 into and out of engagement with the feed-, screw by rotation of cam 47 which lowers and raises a bar 45 on which a roller 46. mounted on the cradle runs.

Title: Control system for digital computer
IPC: G06F9/32
Filed: 1963-03-29
Abstract: 1,043,358. Electric digital calculators. HITACHI Ltd. March 29, 1963 [April 2, 1962], No. 12689/63. Heading G4A. In a digital computer, an instruction word has a bit specifying whether or not a repetitive operation is to be performed, and if it is data addresses are modified after each repetition until the required number of repetitions as specified by a register have been performed, the register also indicating spacing of successive data items. Fig. 6 (not shown), shows a circuit for producing a " repetitive operation incomplete " signal. The instruction word bit mentioned above is gated to a first flip-flop and sets it if a repetitive operation is required. After each repetition, a count field (incremented by one after each repetition) and the number of repetitions required are subtracted, and if the first flip-flop is set, a zero result from the subtraction sets a second flip-flop which allows the first flip-flop to be reset. Generalized arithmetic operation, conditional jump (including associative table look-up) and data transfer instructions as above are described in the Specification with capabilities to successively modify addresses within the instruction words using indexing quantities in registers selected by fields within the words. One instruction enables a succession of stored data items to be tested against a selected condition and the results of the tests stored. The count field and number of repetitions required are stored in respective registers which also store quantities used in determining the spacing in memory between successive items of data to be operated upon.

Patent GB-551998-A (GB)
Title: Improvements in or relating to electrical musical instruments
IPC: G10H1/20
Filed: 1941-10-06
Abstract: 551,998. Electrical musical instruments. ELECTRICAL RESEARCH PRODUCTS, Inc. Oct. 6, 1941, No. 12865. Convention date, Oct. 15, 1940. [Class 88 (ii)] An electrical musical instrument with a non- transposing keyboard and having a plurality of octaves each containing twelve notes tuned to a given key, say C, in Just intonation is provided with means for substantially instantaneously retuning the notes of each of the octaves to sound with Just intonation in any other desired key. The instrument is conveniently of the character set out in Specification 527,058 (U.S.A. Specification 2,126,682), i.e. one wherein twelve oscillators are provided for the top octave and the frequencies for all lower octaves are obtained by cascaded frequency-divider systems 3. Fig. 1 is a schematic diagram of such an instrument. Key-control relays 6 under the control of pedals 7 on the console 1 control the frequencies of the notes according to the key of the music, so that the intervals of the scale are the same for all keys. Retuning is effected by locking-switches 16 operable one at a time to set the frequencies of the notes according to the key of the music, with other switches 17 for momentary use when a chord not properly in the set key occurs. If any switch 16 is operated it will automatically release through latch bar 18 any other switch 16 which may have been previously operated. The relay winding 23 associated with the operated switch 16 becomes energized, the circuit being from source 19, through conductor 20 normally closed series contacts 27, 28, conductor 29, contacts 30, 26 of the operated switch conductor 24, coil 23, and conductor 22 back to source 19. If a momentary switch 17 is operated the circuit then becomes from source 19 through conductor 20, contacts 21, 25 of the operated switch, conductor 24, coil 23 and conductor 22 back to source. Each oscillator circuit comprises a coil 31 and a number of condensers which can be individually connected in parallel with the coil by a unit of that multiple relay which has been brought into operation by the requisite keycontrol pedal 16 or momentary pedal 17. Thus, the lowermost blades of the relays are connected to the coil 31 of oscillator C, the next blades to the coil of oscillator C#, and so on; the condenser 7# of oscillator C is connected to the lowermost contact of relay 7#, the condenser 6# of oscillator C to the lowermost contact of relay 6#, and so on; and the condenser 7# of oscillator C# is connected to the next lowest contact of relay 7#, the condenser 7# of oscillator D is connected to the third contact of relay 7#, and so on. The oscillators are in that way tuned by whichever relay has been rendered operative by a key-control pedal.

Title: Improvements in copper refining methods, apparatus and products
IPC: C22B15/14
Filed: 1931-05-01
Abstract: 378,008. Electric furnaces. AMERICAN METAL CO., Ltd., 61, Broadway, New York, U.S.A.-(Assignees of Heuer, R. P. ; 237, Montgomery Avenue, Haverford, Pennsylvania, U.S.A.) May 1, 1931, No. 12940. Convention date, June 5, 1930. [Class 39 (iii).] In a method of refining copper by treating molten copper with carbon submerged beneath the surface of the copper, the deoxidation takes place under conditions of freedom from contamination with combustion gases and substances containing hydrogen, cuprous oxide is practically eliminated from the copper and the deoxidation is continued to change carbon dioxide in the copper into carbon monoxide so as to unsaturate the metal with carbon dioxide. In refining copper cathodes, the cathodes may be first desulphurized by roasting without melting in a furnace A, Fig. 1, in contact with combustion gases. The desulphurized metal after melting in a reverberatory furnace 17 passes into a deoxidation furnace B through a closed trough 29, Fig. 2, heated by a burner 30, a gate 31 holding back the slag. The furnace B comprises a casing rotatably mounted on rollers 37 filled with carbonaceous material which is forced down by plungers (not shown) operating in tubes 32, 33. The furnace may be heated electrically by electrodes 23, 24 or by any means that does not introduce combustion gases into the furnace. In ordinary working, the furnace is rotated slightly to cast the metal as the level of the pouring spout 36 is above that of the metal in the furnace. For this purpose a gear driving band 39 engages a rack 40 driven by a screw 41. The metal is cast into vertical moulds 46, Fig. 1, on a casting wheel moving in either direction, the stream of molten copper being surrounded with a non- oxidizing gas such as carbon monoxide. Specification 351,740, [Group XII], is referred to.

Title: Improvements in or relating to couplings for pipes, tubes and the like
IPC: F16L37/373
Filed: 1943-08-11
Abstract: 579,132. Pipe couplings. THOMPSON PRODUCTS, Inc. Aug. 11, 1943, No. 12992. Convention date, July 27, 1942. Addition to 352,932. [Class 99 (i)] A modification of the coupling described in the parent Specification comprises a pair of complementary coupling boxes 11, 12 which, when placed together form a hollow cylindrical chamber 21 closed at the bottom 17, 27 but open at the top to receive a split plug valve 13a, 13b which is retained in position by means mounted on the boxes. Part circular guides are provided at 17a, 27a at the bottom and at 23, 33 at the top of the coupling boxes so that the two halves of the valve may be assembled in their respective coupling boxes, Fig. 4, and then placed together whereupon a 90 degree rotation of the valve locks the coupling and causes a cylindrical passage 50 in one of the valve portions to come into alignment with the bores 20, 30 in the coupling boxes and establish a free passage for fluid. Upward movement of the valve parts, Fig. 5, is prevented by top guides 25. When the valve is closed so that the coupling can be disassembled, parts of the valve members, Fig. 6, close the ends of the passages in the coupling boxes to prevent leakage therefrom. When the valve parts are brought together lugs 46 are registered by a pin 49a and together form a head to which a wrench may be applied to rotate the valve. The open and closed positions are determined by abutments. Sealing sleeves 39 urged by spring washers 33 have part-cylindrical surfaces engaging around the valve portions. In a modification, Fig. 11, the top guide pieces 25, 35 are dispensed with. Part circular guides 62, 63 and 64, 65 are provided on the coupling boxes. In this form each valve portion has a spring plunger 75 which carries a key 76 connecting with slots in the part-circular positions 23, 33 to prevent the valve portions being rotated into positions wherein they will be separated from their coupling boxes unless it is required to drain the pipe lines.
