Title: Magnetic core memory operation
IPC: G06F15/00
Filed: 1960-12-13
Abstract: 909,783. Magnetic core memory system. NATIONAL CASH REGISTER CO. Dec. 13, 1960 [Dec. 15, 1959], No. 35053/61. Divided out of 909,781. Class 106 (1). [Also in Group XXXIX] Noise is read-out from a magnetic core matrix is reduced by applying a half-select current on a co-ordinate drive line in the write phase of the preceding read-write cycle. In the example the cores in rows 1 and 3 and in rows 2 and 4 are respectively saturated in opposite directions to represent 1, as shown in the right-hand lower comer of Fig. 1. The sense winding therefore traverses successive rows in opposite directions. Cores 1-4 are read and written into in succession in time intervals t 1 -t 4 , each interval being divided into pause, read, and write sub-intervals, say t 11 -t 13 . In the write sub-interval to preceding interval t 1  a current on line Y1 half-selects all the cores 1-4 in the column to the P-state. At subinterval t11 a current on line X1 half-selects the cores on that row. At sub-interval t 12  this current combines with current on Y 1 to saturate core 1 so that 1 is read out by sensing lead. The read-out is synchronized with a strobe pulse at 7 and fed to output 8. Noise from the other cores on line Y1 is very small since they had previously been half-saturated. At sub-interval t 13  the current on Y1 is reversed, so as to halfselect all the cores on the line to N state. Simultaneously a half-select current is or is not applied to line X1 according to whether 1 or 0 is to be written in core 1. The process repeats for the second row and core 2 with reversed polarity for recording.

Abstract: 793,980. Fluid-actuated valves. INGENIORSFIRMAN FLIESBERG AKTIEBOLAG. Dec. 7, 1955 [Dec. 23, 1954], No. 35100/55. Class 135. A vacuum control valve comprises a valve body 1 having connections 2, 4 with a vacuum pump and a space to be evacuated, respectively, first and second valve members 13, 28 urged towards their respective seats by springs 32, 29, a rod 21 on which the valve members independently slide, loaded at one end by a spring 23 and connected at its other end to a diaphragm 15 (or bellows), and a throttled connection 17 between the valve body chamber 1a and a chamber 19 above the diaphragm. The valve member 13 is constituted by a double-beat valve comprising plane and conical valve members 11, 12 coacting with conical and plane valve seats 9, 10 respectively: the plane valve member just passing through the plane valve seat so that when the valve members are seated they are pressure-balanced. Nuts 31 and a sleeve 30 permit adjustment, so that the valve members 13, 28 may both be seated when the diaphragm 15 is unstressed. On the pressure in the chamber 1a falling below the desired subpressure the diaphragm will be raised against the spring 23 to unseat the valve member 28 to admit atmospheric air from below the diaphragm directly to the chamber 1a to reduce the tendency of the diaphragm to oscillate. On the pressure in the chamber 1a rising above the desired sub-pressure the diaphragm 15 will be lowered to unseat the valve member 13 to connect the pump to the space being evacuated.

Filed: 1937-12-18
Abstract: 496,433. Electrolytic production of white lead. CARRERAS, R. S. Dec. 18, 1937, No. 35135. Convention date, Jan. 15. [Class 41] Pigments are made by heating white lead prepared by. electrolysis of a solution of alkali chlorate saturated with carbonic acid between lead electrodes, the electrolyte being motionless. Preferably 1-10 per cent of the white lead remains unconverted. The electrolysis is carried out in vessels having inclined bottoms, the electrodes are 5 cms. apart and at least 35 cms. from the bottom of the bath, the cathodes have a greater surface than the anodes and are dipped in a solution of a mercury salt and dried prior to use. After separation of the white lead, the liquid may be resaturated with carbon dioxide in a separate vat or a serpentine tube. Each bath has inlet and outlet apertures of preferably equal capacity, the plant consisting of two or more parallel groups, one group being charged or discharged while electrolysis proceeds in the other. An example is given using a 2-4 per cent solution of chlorate of sodium saturated with carbon dioxide and a current density of 0À5-0À7 amps. per sq. decimetre at 1-3 volts for three hours ; the white lead is converted to litharge and the litharge in presence of oxygen to red lead in muffle furnaces. Specifications 277,723 and 298,520, [both in Class 41], are referred to.
Patent GB-649091-A (GB)
Title: Improvements in or relating to the production of carbon black
IPC: C09C1/50
Filed: 1946-11-27
Abstract: Carbon black suitable for rubber compounding is produced by introducing vaporized oil having a low A.P.I. gravity, a low boiling range and a low end point into a cylindrical reaction chamber to maintain therein a longitudinal stream of reactant hydrocarbon, introducing free oxygen-containing gas tangentially to the inner wall of the reaction chamber to provide temperatures therein sufficient to decompose a portion of the reactant hydrocarbon to carbon black, passing the resulting mixture through a semi-insulated after-reactor chamber of equal length and diameter to the reaction chamber to complete the carbon black formation with a limited heat loss therein, shock cooling to 1500 DEG  F. and separating carbon black.  Recycle gas oil, of 16-25 DEG  A.P.I. gravity and of which at least 90 per cent is vaporized at 700 DEG  F., preheated to 700 DEG  F. is introduced at 16 into reactor 10, having sillimanite lining 11 enclosed in insulation 12 with steel shell 13, at a rate defined by the formula V = 50D3 where V = gallons of gas oil per hour and D = diameter of reactor in feet. Air is introduced through annular tube 19.  Preheated air <PICT:0649091/III/1> is injected through one or more tangential pipes 15A, 15B, at a rate of 400 cu. feet per gallon of oil, to form a helically moving layer to prevent carbon deposition on the reactor walls and to maintain the reactor at 2100-2400 DEG  F. by reaction with the oil. The resulting gases pass to after-reaction 25, having sillimanite lining 11A only, and thence to the cooling assembly consisting of water jacketted cooler 35 with water spray 14, air cooling pipe and spray quencher (not shown); the carbon black is separated in an electrical precipitator or bag filter.  Burner 15B may be of greater diameter than 15A and the length to diameter ratio for the reactor 10 may be 4.8.  Specifications 607,296 and 621,031 are referred to.
Patent GB-785516-A (GB)
Title: Improvements in or relating to template switching arrangements for copying lathes and like machines
IPC: B23Q35/08
Filed: 1955-12-07
Abstract: 785,516. Copy-turning. FISCHER AKT.- GES., G. Dec. 7, 1955 [Dec. 7, 1954], No. 35195/55. Class 83 (3). A templet-changing arrangement for a copying-lathe &c. to perform two different turning or like operations in accordance with a pair of templets successively on the same workpiece, the latter being repositioned in the machine between operations, comprises changing means for moving each templet in turn into the operative position and sensing means for actuating the changing means in dependence upon the position of a part of the work, e.g. a collar, in the machine. The work 10, Figs. 1 and 2, is carried by a chuck 9 and tailstock 8 and has a flange 46 which, for the first turning operation I (heavy lines) is nearer the tailstock. A tool 12 is mounted on a copying-slide 11 controlled by hydraulic or electric means (not described), and having a follower 14 which co-operates with one or other of a pair of templets 15, 25, Fig. 3. The latter are mounted on a rockable support 17 which is moved automatically to bring the second templet 25 into co-operation with the follower for the second operation II, Fig. 2. The work is repositioned for the latter operation with the flange nearer the headstock. When brought into this position the flange 46 on the work contacts a switch-roller 39, Fig. 3, carried by a switch-box 37, Fig. 1, adjustable on a top beam 3 of the machine. The roller 39, Fig. 3, is thus raised and a tapered collar on the stem supporting the roller moves a switch 40 to the right. An electric circuit is thus completed from a power line to the coil 24 of an electromagnet and closed switches 42, 43. A slide valve 22 is moved to the right by the electromagnet and fluid allowed to pass from cylinder 30 to reservoir 19 so that piston 32 is relieved from fluid pressure and is moved to the right by a spring 31. A linkage 33-36, connected between the piston and templet carrier, rocks the latter to the position where templet 25 is operative for the cutting cycle II. Rocking the templet carrier moves a switch 42 to the left-hand position for conditioning an electromagnetic 23 for the next operation, where templet 15 is required. When the tool 12 moves forward to start the cut of cycle II a cam 47 moves off a switch arm and the circuit to a relay 43a is broken so that switch 43 is opened. This breaks the circuit to prevent inadvertent operation of the templets until the tool is retracted again for the next operation. A modified arrangement is described using electrical means only and the safety switch 47 may be embodied in the tailstock spindle instead of the tool.

Abstract: 1,167,937. Towing conveyers. SOVEX Ltd. 31 July, 1968 [1 Aug., 1967], No. 35222/67. Heading B7L. A conveyer system comprises a main track 1 and a branch track 2 forming a loop from the main track, a driving chain 11, a driving trolley 7 running on track 1 consisting rails 3, 4 and operatively connected to the chain, a bar 8 pivotally connected to trolley 7 at one end and at the other end to a driven trolley 10, wherein the trolley 10 is by means of a switch arrangement adapted to run either on the main track 1 or branch track 2 and to be releasably connected to a truck 21. Intermediate trolleys 9 serve to support the chain. The bar 8 may be formed with a telescopic connection at its rear end and the trolley 10 formed with an open sided box 19 into which the top end of a mast 20 of the truck 21 engages. A latch 39 mechanism retains the mast in the box until it is pivoted upwards allowing a rear door 36 to be pivoted up and the mast to escape. In a modification when a buffer 42 strikes a stop parallel linkage 43 operates to lower the mast and thereby release it from box 19. In an arrangement where the trolley 10 passes through the branch track 2 without stopping a mechanism may be employed whereby the truck platform is lowered until a pallet thereon is resting on the ground while the truck moves from therebeneath. A switch mechanism to divert only trolley 10 on to the branch track comprises a striker plate 30 which operates a deflector plate 24. The deflector plate 24 is returned to its full line position either by the trolley 10 contacting a return striker-plate in the branch track or a following trolley 7 striking a roller in the main track connected with plate 24. Striker plate only operates plate 24 if a solenoid 31 is energized. The rails 3, 4 are inwardly facing U- section having trolley wheels running on the inner faces of the lower flanges with for trolleys 7 and 10 horizontal wheels between the lower rail flanges.

Abstract: 309,480. Hesser Maschinenfabrik- Akt.-Ges., F. April 11, 1939, [Convention date]. Weighing - apparatus fitted to packeting- machines.-In a packeting machine wherein the packages are conveyed stepwise and in succession to various stations for filling, weighing, closing and other treatment two roughly filled packages are fed simultaneously forward by the distance of two stations or by two feed steps, underneath two weighing devices, remain there during the next step of the feeding mechanism, are then likewise simultaneously fed by the distance of two stations, and are hereafter in known manner individually and stepwise conveyed to the further stations of the filling and closing machine. By the use of two weighing devices, ample time is given for the weighing operations without interfering with the high speed of the closing and other devices. The empty packages a pass successively from a forming machine to a member 1 which swings them into a vertical position beneath a measuring .device D at the station I where they receive the bulk of their charge in known manner. The packages are conveyed intermittently, by cam mechanism driven from a shaft 7, to an idle station II, two weighing stations III, IV and to other stations V, VI, &c. for closing. gumming, labelling, &c. The package-feeding mechanism is of the usual form in connection with the stations V, VI, &c. but operates as described below at the preceding stations. The packages are pushed forward by arms or grippers 2 - - 5 which, under the control of the cam shaft 7, receive reciprocatory movements in the line of packages and swinging movments into and out of engagement with the packages. Assuming the grippers to have moved to the right by the distance of two stations in order to feed two weighed packages simultaneously from the stations III, IV to the stations V, VI and to convey two roughly filled packages from the stations I, II to the stations III, IV, the grippers are then swung away from the packages and moved back to their left-hand positions, an empty package being at the same time brought to the station I and roughly filled. The gripper 2 alone is now swung forward to operative position and a feed step to the right is again made by all the grippers thus bringing the roughly filled packet to the idle station II without however disturbing the packages at the weighing stations III, IV. The grippers are now returned to the left-hand position and are all swung forward into operative position and are then moved two steps to the right and the cycle of operations is repeated.

Abstract: 829,313. Packaging machines. FORGROVE MACHINERY CO. Ltd. Feb. 19, 1958 [Nov. 23, 1956], No. 35955/56. Class 94(1). A device for separating a group of articles such as biscuits 11 from a column moved forward on a surface 12 by conveyer belts &c., comprises a step 18 at the end of the surface and a presser for pressing at least the last one of the articles which has been advanced beyond the step against a further supporting surface, means being provided to form positively a gap between the last article past the step and the first of those preceding it. The leading end of the column is supported by a plate, Figs. 1, 2, 9 (not shown), moving with it as it advances and returning during or after removal of the group.  In one embodiment, Figs. 3, 5, 7, after the presser 38 has operated, a member 35 having combined horizontal and reciprocating motion rises so that its forward end enters between the articles on either side of the step. It then moves back to form a gap into which separator elements 27 rise, after which the group is ejected by a pusher operating transversely of the direction of movement of the column. The pusher 45 may place the group between fingers 65 which are moved by a rod 66 to sweep it into pockets 62 of a conveyer, Fig. 7. The conveyer may be as described in Specification 684,254. In another embodiment, Fig. 10, two pushers 138, 238 engage the articles, and separation is achieved by a single member 35 which is projected from the step 18 to tilt the articles of the group. The articles may feed directly into a conveyer 61 which forms the further supporting surface. The supporting surface 12 need not necessarily be horizontal. Movement of the leading end support plate operates switches to stop or start article feed and initiate or end the separating action.
