Title: Electrically-driven shearing apparatus
IPC: B26D3/16
Filed: 1959-03-06
Abstract: 904,755. Control of A.C. motors. REIFENHAUSER G.m.b.H. March 6, 1959 [April 5, 1958], No. 7931/59. Class 38 (3). Tubing is cut into predetermined lengths by means of a sickle-shaped shear driven by a squirrel-cage induction motor 15 having a mechanical brake which is capable of slipping. The tubing is continuously advanced past the shears, and a photo-electric switch 33 is closed when the front end of the tube reaches a predetermined position corresponding to the length which it is desired to cut. Closure of switch 33 closes a contactor 14 for energizing the motor 15 and releasing the brake, the motor reaching full speed after its shaft has turned through a predetermined angle. The cutting operation is performed whilst the motor is rotating through a further predetermined angle, whereupon a switch 6 is depressed by a motordriven cam to de-energize the motor, apply the brake, and to open the contactor 14. The motor is brought to a standstill when it has completed substantially one complete revolution. The switch 6 is held in its depressed position by means of a spring-biased latch 11, and, when the switch is depressed, a time-delay relay 26 is de-energized so that solenoid winding 29 is energized for a short period. This withdraws the latch 11 and allows the switch 6 to re-close its contacts, the circuit for the solenoid winding 29 being then broken.

Title: Improvements in and relating to the desulphurization of pig iron
IPC: C21C1/02
Filed: 1946-03-15
Abstract: In a process of desulphurizing pig iron by means of a desulphurizing slag under strong reducing conditions, a gas is passed into the molten mass in a closed, unfired vessel in such quantity, not less than four times the volume of the iron, and with such provision for the escape of excess gas, that carbon monoxide is continuously discharged from the vessel with consequent reduction of the partial pressure of oxygen at the iron slag interface.  The gas used may be hydrogen, nitrogen, a mixture of hydrogen and nitrogen or blast furnace gas treated to remove CO, or CO and CO2, and the amount of CO present should never exceed 40 per cent.  A layer of slag comprising lime, fluorspar and blast furnace slag may be supported on the metal in a rotatable vessel lined with a carbon refractory and the stream of gas not exceeding sixteen times the volume of iron passed through at least half the depth of metal and slag.  The amount of sulphur remaining in the iron depends on the volume of gas used and it is stated that 0.003 per cent S may be obtained. Specification 499,302 is referred to.

Abstract: 918,351. Photographic cameras; presetting diaphragms. DECKEL, H., and DECKEL, F. W. March 10, 1959 [March 21, 1958], No. 8200/59. Class 98 (1). A photographic camera of the kind having a diaphragm preselector mechanism and having mounted thereon an exchangeable objective, wherein a diaphragm blade control-ring accommodated in the objective mount is presettable by means of a diaphragm setting ring located in the camera, and is driven against spring loading from the preset position towards a position in which the diaphragm blades are open, by engagement with a rotatable driving ring forming part of the shutters mechanism mounted in the camera, is characterized in that first and second intermediate rings are mounted in said objective mount for rotation about the optical axis of the objective, said first intermediate ring being coupled to the diaphragm blade control ring and engaging said driving ring, whereas said second intermediate ring, for purposes of presetting the aperture is rotatable by means of said diaphragm setting ring and serves to limit the rotation of said first intermediate ring. As shown, an exchangeable objective 22 is mounted on the camera front by a bayonet connection 24. A spring-urged diaphragm blade control ring 40 coupled to a first intermediate ring 64 has its rotation towards its aperture-closed-  position limited (for purposes of presetting the aperture) in that said ring 64 is engaged by a projection 82 of a second intermediate ring 74 which is coupled to a diaphragm setting ring 16 by means of projections 76, 80 maintained in engagement by pressure of a spring 78 acting on said ring 74. The ring 16 is releasably retained in its set position by detent means 20. The diaphragm may be moved into its maximum aperture position and returned to its preset position by means of a driving ring 58, forming part of the shutter mechanism (not shown, but housed in space 6) which has an arm 60 engageable with a projection 62 of the ring 64. In a modification (Fig. 2, not shown), connection 76, 80 is arranged axially above connection 62, 60 but the mechanism functions in exactly the same way. The shutter is provided with a speed setting ring 14 which is also releasably retained in its set positions by a detent means 18. The diaphragm detent means 20 may be dispensed with if the setting ring 16 is couplable to the ring 14 for purposes of setting the camera according to light values. Focusing is obtained by rotating a ring 32 which is in screw-thread engagement with a non-rotatably mounted lens tube 34, manipulating projections 30 being provided for this purpose.

IPC: G11C19/20
Filed: 1953-03-27
Abstract: 766,987. Electronic counting-apparatus; electric digital-data-storage apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 15, 1954 [March 27, 1953], No. 8474/53. Class 106 (1). A shifting register comprises a chain of electronic discharge tubes so connected that a pattern of conductivity of the tubes can be progressed successively along the chain by the application of switching pulses to the tubes which are capacitively coupled so that when a tube having been switched from a first condition to a second is then restored to the first the next tube of the series is switched from a first to a second condition. Fig. 1 shows a binary shifting register in which initially one tube only of the chain, for example tube V2 is cut-off and the other tubes V1, V3 ... V4 are conducting. Positive switching pulses 12, 13, &c. are applied via diodes D1, D2, &c. so that the grid voltage of tube V2 rises and V2 conducts. The anode voltage of tube V2 falls to a limit set by diode L2 and the drop in voltage is applied via capacitive potentiometer C2, C<SP>1</SP>2 to cut-off tube V3 as the capacitive potentiometer C<SP>11</SP>3, C<SP>1</SP>2 is such that the proportion of the switching pulse voltage applied via diode D3 is insufficiently large to prevent this. Successive switching pulses progress the pattern of conductivity along the chain. In a modification, Fig. 2 (not shown), the switching pulses may be applied alternately to alternate valves of the chain as described in connection with Fig. 1 of Specification 766,988. Specification 738,739 also is referred to.

Title: Teleprinter for automatic telegraph exchange systems
IPC: H04L12/02
Filed: 1952-04-03
Abstract: 710,591. Impulse transmitters. AUTELCA AKT.-GES. April 3, 1952 [April 6, 1951], No. 8558/52. Class 40 (4) [Also in Group XL (b)] An impulse generator for a number selector is directly controlled by the digital keys of a teleprinter for use in an-automatic telegraph exchange system operating on a digital basis. The depression of a key 1 seizes a free selector at the exchange, locks the keys except those allotted to numerals and moves a claw clutch member 2 to connect a shaft 3 via a friction clutch 5 to a gear wheel 4 of the teleprinter drive. The depression of a key 7, Fig. 3, allocated on the teleprinter keyboard to a numeral, rocks a lever 9 into engagement with a guide member 22 and a pin 16 is brought to the inlet 10 of a spiral groove 11a, with a number of turns corresponding to the number of impulses for the numeral key 7 which has been operated. The lever 9 also engages a lateral projection 13 on a release lever 12 which rocks a shaft 8 so that the hump 14a on a cam 14 removes a pivoted latch 15 from a tooth on a cam 6 on the shaft 3 which is released to be driven from the gear wheel 4. Cam positions 17a on the impulse cam 17 effect transmission of selecting impulses, the number being determined by the effective length of the groove 11a. At the end of the appropriate impulse series the pin 16 enters at 21a an outer groove 21 so that the shaft 8 is rotated further and a cam 20 opens contacts 19 to prevent further impulses passing to the line. At the outer end of the groove 21, the lever 9 becomes clear of the guide member 22 and is returned to its normal position by means of a spring 23 acting on the release lever 12 which restores the shaft 8 so that the latch 15 is positioned to arrest the shaft 3 until the succeeding numeral is to be transmitted.

Title: Mineral separation
Inventor: COMBER FREDERICK ROY
IPC: C01F17/00

Abstract: 1,223,682. Separation of Thorium, Cerium, Ytterbium and Yttrium. W. J. REYNOLDS HOLDINGS Ltd. 15 Feb., 1968 [23 Feb., 1967], No. 8795/67. Heading C1A. The separation of Th from Ce<SP>IV</SP> or Yb<SP>III</SP> from Y is effected by the preparation of their alkali metal double carbonates and crystallization thereof in alkali metal carbonate solution. To separate Thorium it is preferable that the starting material contains water-soluble Th compounds and light rare earths (i.e. elements with atomic nos. 57-63 inclusive) and only a minor proportion of Y. This can be achieved by the method as in Specification 1,223,683. Any Cerium present is oxidized to the Ce<SP>IV</SP> state. The water-solubles from the process are converted to carbonates and the soluble carbonates dissolved in alkali metal carbonate solution, insoluble carbonates removed and solution treated to reduce Ce<SP>IV</SP> to Ce<SP>III</SP> which is removed. Thorium alkali metal double carbonate is crystallized out. Cerium is separated by oxidizing the pptd Ce<SP>III</SP> carbonate and then forming double carbonate as with Th. Yttrium is separated from materials containing water-soluble Y compounds, preferably with very low Yb content so that reduction to Yb<SP>II</SP> is unnecessary. The alkali metal carbonate solution is used at concas, greater than 10%. The double carbonate may be converted to oxalate or nitrate and then to the oxide.

Title: Improvements in or relating to parachutes
IPC: B64D1/02
Filed: 1922-03-31
Abstract: 199,508. McKenna, H. W. March 31, 1922. Parachutes.-In a device for landing gcods, of the type comprising a container for holding a main parachute and a pilot parachute and fitted with retaining gear adapted to be released by clockwork after a predetermined time interval after the discharge of the container from the aircraft, the two parachutes are arranged in tandem and separated by a rigid withdrawable partition which carries the retaining gear and the clockwork mechanism. In the arrangement described, a small parachute 17, Fig. 1, and a main parachute 16, connected in tandem, are packed in a cylindrical container 10 closed at its lower end by a plate 11 to which is .fastened the rigging lines of the main parachute 16. The container is divided into separate compartments 14, 15 for the two parachutes by a disc partition 13, held between two nuts on the rod 23 to which are connected ropes 19 from the apex of the main parachute 16, and the rigging lines 20 of the small parachute 17. Hinged on studs 29 on the perimeter of the partition 13 are four radial arms 24 - - 27, Fig. 3, which fold over to lie parallel with the plane of the partition, their forked ends 32 overlapping around the rod 23, and their outer ends engaging in slots in the container wall and preventing the withdrawal of the partition 13. In this position a locking arm 33 mounted on a rotatable pivot on the partition, passes over that arm 24 the forked end of which overlaps the other three arms, and its outer end 35 is held in the fork of a catch 36, Fig. 5 (mounted on the partition), by a cover 37 normally pressed down by one end of a lever 39 pivoted on the partition and' acted upon by a spring 41. The other end .of the lever 39 rides on the edge of a notched cam 42 fixed on the driving wheel of a clockwork motor 43. The cam 42 is adjustable on its spindle in order that the position of the notch relative to the lever 39 may be varied. The goods holder is hung from the lower end plate 11, and the small parachute 17 held in position by a releasable cover (not shown) and attached at its apex to the aircraft by means of a breaking line. When the device is released from the aircraft the small parachute opens and a brake or other control on the clockwork 43 is released by the pull of the breaking cord. The holder falls rapidly towards the landing place until after a predetermined time the end of the lever 39 is pressed into the notch on the cam 42, the cover 37 is released, and the locking arm 33 is ejected from the fork in the catch 36 by a spring plunger 38. The radial arms 24 - - 27 are thereby freed and the pull of the small parachute withdraws the partition 13, together with main parachute 16, from the container 10. The main parachute then opens and causes the device to land at a slow speed.
