Title: Method of and means for ensuring accurate adjustment or "pitching" and for indicating the movement of traversible carriages or supports in mill engraving or marking-out or like apparatus where division or spaced setting is requisite
IPC: B23Q16/02
Filed: 1931-11-27
Abstract: 387,790. Linear spacing-mechanism. MOULTON, Ltd., G., Whitley Street, Rochdate Road, and VARLEY, G. P., 22, Hermitage Road, Crumpsall, both in Manchester. Nov. 27, 1931, No. 32870. [Class 83 (iii).] Gauging devices.-In a device for accurately determining linear spacing movements of the carriages of mill-engraving, marking-out, or like apparatus the carriage movement, effected by the usual traversing-mechanism such as a lead screw, is multiplied and indicated by an attachment including dial and pointer mechanism associated with an independent measuring device, means being provided to return the pointer to zero after each spacing movement. In an application to a millengraving machine, a roller e carried on a mandrel e<1> is engraved by a tool a connected with a carriage b which is traversed along the bed c by a screw d. The screw may be manually rotated to effect the desired movements of the carriage either from a dividing wheel mounted on the screw d or preferably from a handwheel f<3> on a shaft f<2> connected to the screw by worm reducing gear f<4> and gears f<6>, d<1>. A quadrant or sector h secured to a bracket on the machine bed and marked with graduations h<2> coacts with a pointer i secured to a hub which is rotatable on a stud g<1>. A flexible steel tape passes round the hub and its end portions are secured to brackets k<1>, k<2> on a bar m which is urged by a spring m<1> so that, at a chosen zero position of the pointer, an abutment m<2> on the bar engages an adjustable abutment screw m<3>. The bar may be secured to the travelling carriage by a clamp n. The movements of the bar m may be magnified eight times by the pointer so that in operation, if a series of spacing, movements of <1>/16-inch of the carriage-are required, the bar is first locked to the carriage .and the screw d turned by the operator to move the carriage until the pointer has moved over ¢-inch on its quadrant. The clamp n is then released whereupon the bar m is returned by its spring to re-engage the abutments m<2>, m<3> and restore the pointer to zero. The bar is then reclamped and another spacing movement effected by turning the screw d and so on. The flexible band may-be-replaced by rack-and-pinion mechanism and a microscope may be provided to facilitate the reading of the scale h<2>.

Title: Pack opening and sheet receiving means
IPC: B21B47/04
Filed: 1946-11-06
Abstract: 618,699. Separating sheets in pack rolling. WILLIAMS, W. P. (Armco International Corporation). Nov. 6, 1946, No. 33042. [Class 83 (iv)] Apparatus for separating the sheets of a rolled pack comprises means for clamping the pack to a bed, a carriage on which are mounted pinch rolls between which the free ends of a sheet may be introduced, and means for driving the rolls and for traversing the carriage so that the sheet is stripped from the pack. When the pack leaves the rolling mill, one edge is sheared and the pack is fed on to a roller-table 2, Fig. 1, with the sheared edge abutting a stop 5. Alignment of the pack is facilitated by a pivoted guide element 6. When correctly positioned, one corner of the pack overhangs a cut-away corner 3a of a supplementary table 3 and in this position it is held by a pneumatically operated clamp, while a device 14 comprising an angle-iron with transverse members welded across the angle, is reciprocated vertically in contact with the corner of the pack to effect a partial separation of the sheets. The clamp is then released and the pack manipulated by the operator along the table 2 and on to a second roller table 19, Fig. 3, preferably slightly inclined, where the pack is held by magnetic hold-down devices illustrated at 21 and 22. On a track 23 just above the level of the table is a carriage 24 carrying a pair of pinch rolls 26, 27 adapted to be driven by a motor 33, while the carriage itself may be traversed along the track in either direction by a reversible motor 37 operating an endless chain 34 to which the carriage is secured. A framework 30 extends forwardly from the carriage. In operation, a sheet from the partially freed end of the pack is pulled up manually by means of tongs and inserted between the rolls 26, 27 which may be continuously driven. As soon as the end of the sheet has passed a short distance through the rolls, it actuates a switch 39, Fig. 4, to begin the forward traverse of the carriage so that the sheet is stripped from the pack and rests on the framework 30. At the end of the traverse, the carriage actuates a switch 41 to effect the return traverse, until the actuation of a third switch 42 stops the motor 37. The forward traverse of the carriage carries the end of the stripped sheet between a pair of pinch rolls 73, 74, Fig. 9, by which it is fed along two drop plates, which may be released to lower the strip on to the top of a stack 59 resting on a conveyer 60. On the drop plates, the sheet is positioned by an adjustable stop 50, while the sheets of the stack are aligned against a fixed stop 62 by means of a pivoted, pneumatically operated guide or pusher 63. Before being released by the drop plate on to the stack, the sheets may be inspected and those rejected may be thrown over the side on to a waste dump by means of a pneumatically operated arm 80 (Fig. 11, not shown).

Patent GB-403797-A (GB)
Title: Improvements relating to carburettors for internal combustion engines
IPC: F02M7/20
Filed: 1932-11-24
Abstract: 403,797. Spray carburetters. SOC. ANON. SOLEX, 190, Avenue de Neuilly, Neuilly-sur-Seine, France. Nov. 24, 1932, No. 33252. Convention date, Jan. 21. [Class 7 (iii).] The maximum engine speed is limited to a predetermined value by using the suctions existing in front of and beyond the throttle valve in combination to stop the feed of fuel to the nozzle when these combined suctions exceed that corresponding to the maximum engine speed. The ratio of the suctions may be arranged so that the magnitude of the combined suctions is independent of the position of the throttle to produce a single maximum speed, or so that the magnitude of the combined suctions is dependent on the throttle position to produce various maximum speeds. As shown in Fig. 1, the suction is transmitted to the float chamber 1 through orifices 5, 6, a chamber 3, and a passage 2, and causes the fuel level in a well 12 beyond the nozzle to fall. As the maximum speed is approached, air enters through the well 12 and a calibrated orifice 11 to stop the fuel flow to the nozzle 10. The chamber 2 communicates with the atmosphere through a calibrated orifice 7‹. To suppress the suction during slow running, either (1) the orifice 5 enters the mixing conduit 1a at a point which is a little in front of the throttle valve 4 when closed, (2) the throttle valve carries an extension to close the passage between the orifice 5 and the float chamber 1 when the valve is closed, or (3) the chamber 3 is put into communication with the atmosphere by apertures 8 which open into a recess 9 in the axis of the valve 4 when it is nearly closed. In a modified construction, the fuel flow to the nozzle is interrupted by a closure member attached to a piston which is exposed on one side to the suctions beyond and in front of the throttle, and on the other side to atmospheric pressure.

Patent GB-1397273-A (GB)
Title: Data processing system
IPC: G06F3/06
Filed: 1972-07-18
Abstract: 1397273 Data processing system INTERNATIONAL BUSINESS MACHINES CORP 18 July 1972 [4 Aug 1971] 33503/72 Heading G4A A data processing system includes a control unit and a peripheral unit adapted to assume certain states of operational readiness under control of the control unit, the peripheral including an oscillator adapted during transitions between states of operational readiness to transmit an oscillating signal to the control unit, and a means to detect the assumption of a specified state, such detection causing the oscillating signal to be terminated thereby signalling to the control unit that the transition is ended. The system includes a CPU connected to a microprogram controlled I/O control unit 10 which in turn is connected to one or more magnetic tape peripherals 11. The CPU instructs control unit 10 to select a tape unit, which assuming it is not busy, energizes " not busy " line 36. The tape unit is then instructed to send pulses over line 20 by the actuation of command line 18 and command bus 33. The command is decoded by logic 112 to set latch 51 which enables AND 53 to connect oscillator 120 to line 20. The control unit 10 then disconnects itself, enabling other control units to select the tape. However unless a control unit has specific flags set in its memory it will not select a peripheral emitting pulses on line 20. Sensors 114 provide a signal indicating that a tape has been correctly loaded in the selected tape unit and the control unit via line 54, disables AND 53 and, via OR 133 applies a steady signal to line 20. Thus the tape unit applies pulses to line 20 until it is set in a particular state of operational readiness, in this case " tape loaded ". Other states in which an oscillating signal is emitted include the state where the tape has been instructed to wind on to a particular start mark and is still in the process of winding, during the passage under the heads of an inter-block gap during a writing operation, and during movement of the tape in a direction opposite to that commanded by the control unit, a procedure which is always adopted when tape movement is required to remove tape wrinkles, actual tape position being determined from tachometer signals from generator 109.

Title: Improvement in manufacture of hydrate dextrose from high purity solutions
IPC: C13K1/06
Filed: 1930-11-07
Abstract: Crystalline hydrated dextrose of 99-100 per cent purity is obtained from starch converted dextrose solutions without the use of foots or seed crystals, by supersaturating a dextrose solution having a purity of 96-100 per cent and a density between 36-38 DEG  Baum<\>ae to bring about crystallization.  The supersaturation may be brought about by gradual cooling with slow agitation.  Tendency to the production of anhydrous crystals is prevented by the low specific gravity of the solution.  Dextrose solution of 97 per cent purity prepared by melting solid dextrose is concentrated to 37 DEG Baum<\>ae and cooled to 100 DEG  F. without stirring.  The solution is then introduced into an ordinary crystallizer provided with a slowly revolving agitator and cooled gradually to 95 DEG  F. without circulating water through the jacket.  The massecuite which may have reached a final temperature of 85 DEG  F. is purged and washed in the usual manner.
