Filed: 1974-02-07
Abstract: 1450982 Precipitating heavy metals STORA KOPPARBERGS BERGSLAGS AB 5 Feb 1974 [21 Feb 1973] 05713/74 Heading C1A Heavy metals are precipitated, in a form suitable for use as alloying additives in metal smelting furnaces, out of an acidic aqueous solution containing sulphuric acid and more than 2 g./l. heavy metal, by the steps of: at 30- 90‹ C., adding alkali metal hydroxide to bring the pH up to about 8, while stirring the solution; adding a calciferous or siliceous filter aid that is insoluble at that pH and is suitable for use as an additive for metal smelting; filtering the resultant slurry; and washing and drying the filter cake. Where the acidic aqueous solution contains fluoride ions, as a preliminary step, a quantity of calcium ions stoichiometrically equivalent to the fluoride ion content may be added, while maintaining the pH no greater than 4, so that calcium fluoride is precipitated during the subsequent raising of the pH to about 8. The heavy metals exemplified include iron, chromium and nickel.

Title: Improvements in or relating to electrical pulse distributors
Inventor: BRANCH MAURICE CHARLES
IPC: H04J3/04
Filed: 1958-02-26
Abstract: 819,518. Multi-stable-state pulse distributer circuits. STANDARD TELEPHONES & CABLES Ltd. Feb. 26, 1958, No. 6168/58. Class 40 (6). The Figure shows a multi-stable-state pulse distributer circuit in which the individual pulses of a pulse train applied to input IP appear sequentially at outputs 01, 02 ... ON. Cold cathode gas tube V1 is initially fired by applying a negative pulse on the reset terminal RT, the other tubes V2 ... VN are extinguished by the drop in the common load resistor R2 so that at the end of the reset pulse tube V1 alone remains fired. The positive voltage at its cathode primes thyratron T1 at its control grid so that the next positive pulse at terminal IP causes tube T1 alone to fire the positive pulse at its cathode appearing at output terminal O1 This output pulse is also applied via rectifier MR2 to the grid of cathode follower tube VA which conducts applying positive voltage to the beam tetrode tubes VB, VC. These tubes conduct heavily so that there is a large voltage drop in common load resistor R2, and tube V1 is cut off when the positive pulse on the input lead IP ends. As tube T1 is also cut off the negative voltage at its anode causes tube VA and thus tubes VB, VC to be non-conductive and the anode voltage of the cold cathode tubes V1, V2 &c., is restored. The negative voltage from the cathode of tube V1 is applied to the cathode of tube V2 which fires, the positive voltage at its cathode priming tube T2 so that the next pulse causes this tube to fire and via tubes VA, VB, VC cuts off the cold cathode tube V2. When the pulse ends thyratron T2 is cut off and the next tube (V3, not shown) is fired from tube T2. Since the chain of tubes is a closed one the process repeats itself output pulses being taken from leads O1 02 ... ON sequentially. If a fault develops in one thyratron so the pulse is not passed by it tubes VA, VB, VC will not operate and the associated cold cathode tube will remain conducting indicating the existence of a fault.

Filed: 1929-02-26
Abstract: 328,372. Jackson, L. Mellersh-, (Rhodes- Hochriem Manufacturing Co.). Feb. 26, 1929. Printed records, apparatus for giving. - A weighing and ticket-printing machine of the type having a scale beam and a printing wheel is provided with a rack and pinion for transmitting the motion of the scale beam to the printing wheel, sealing mechanism having lost motion connecting the scale beam with the rack, and means for absorbing the lost motion when the scale beam comes to rest. The load on the platform draws down a rod 12 coupled to a beam 27 fulcrumed at one end on a bearing 28 and connected at the other end to a weighing spring 29. A pin 35 on the beam engages a slot in a sealing bar 36 attached to a rack segment 38 which rotates the type disc 45 by means of a pinion 41<1> mounted on the spindle 41 of the type disc. The upper edge of the slot may be filed so that equal movements are imparted to the printing wheel for equal increments of weight on the platform. In order to take up loose movement between the segment 38 and pinion 41<1> and between the pin 35 and its slot, a cord B carrying a weight G is wound upon a grooved pulley A and is guided clear of the mechanism by a pulley C and a projection F carried by a bracket E. Specification 277,600 is referred to.

Title: Radio direction finders
IPC: G01S1/02
Filed: 1946-03-01
Abstract: 789,799. Radio direction-finding; aerials. STANDARD TELEPHONES & CABLES, Ltd. March 1, 1946 [Sept. 11, 1944], No. 6450/46. Class 40 (7). Relates to direction-finders of the type in which the receiver directional characteristic is scanned through a wide arc the received signals being applied to deflect an arcuate trace produced synchronously with the scanning. According to the invention, means are provided for producing a plurality of directional patterns which are scanned successively through substantially contiguous angles within the arc and the invention is particularly applicable to obtaining a 360 degrees azimuthal scan with a directionfinder mounted in such a location where it is impossible to obtain such a scan with a single aerial system. As shown in Fig. 1, each aerial system 1-4 produces a directive pattern with a sharp central minimum which is scanned from - 45 degrees to + 45 degrees about the horizontal axis of the system, Fig. 3 (not shown), and the four systems are arranged with their axes in space quadrature the scanning being performed successively through the four quadrants 1a to 4a so that the resultant effect is that of a single pattern scanned continuously through 360 degrees. Each aerial system is backed by a screen 19 and as illustrated in Fig. 2 (not shown) is of the type disclosed in Specification 685,990 which shows two spaced aerials 16 and 17 coupled by a transposed transmission line the output being taken from a slidable tapping on the line and as applied to the present invention the tappings are oscillated sequentially by eccentrics driven by synchronous motors 20 which are controlled by the A.C. source 22. The outputs from the aerial systems are applied successively to the receiver 11 through a switching circuit 9 controlled by the source 22 and the output from the receiver is applied to inwardly deflect the circular trace of the cathode-ray tube 14 which is produced by rotating the deflector coil 13 by the synchronous motor 24 also controlled by the source 22. The successive patterns may overlap slightly and a larger number n of aerial systems may be employed provided each aerial scans an angle not less than 360 degrees/n. A trace with a sharp peak 49, Fig. 6, corresponding to the position of the null of the directional patterns is thus produced. When the transmitting station is radiating pulses, the cathode-rav beam will trace a series of lines as indicated by the shaded area 48 but the sharp peak is still clearly visible. Figs. 7 and 8 (not shown) illustrate suitable positions for mounting the aerial systems on aircraft, e.g. aerials 1 and 3 may be mounted on opposite sides of the tail fin and aerials 2 and 4 in the nose and tail respectively; alternatively two forward locking aerials may be mounted on the leading edges of the wings the two directional patterns being simultaneously scanned through the same 90 degree angle and the two outputs being simultaneously coupled to the receiver.
Patent GB-676524-A (GB)
Title: Improvements in or relating to thermostats
IPC: G05D23/275
Filed: 1949-03-10
Abstract: 676,524. Thermal switches. ELECTROLUX, Ltd. March 10, 1949. [March 13, 1948] No. 6524/49. Class 38 (v). A thermal switch, e.g. for controlling the temperature of electrically operated refrigerators, has a spindle 21 connected to the movable end of a bellows 16 so that the temperature range within which the controlled electrical circuit is made and broken is varied by adjustment of the effective length of the spindle by means of a regulating member such as a knob 31 and associated pin 25. Moreover, on both making and breaking the circuit, the bellows is subjected to the same external magnetic force (producing or allowing snap-action of a movable switch member such as a lever 38 bearing contacts 42) independently of the temperature at which the switch is set to operate. A pilot bulb 13 communicates by tube 15 with the bellows 16. Silver contacts on a fixed plate 34 are bridged by silver contacts 42 on the lever 38 which is pivoted on a pin 39 and has an oval opening 40 the edges of which, when the bellows contracts, bear a conical collar 22 slidable on the spindle 21 but held by a spring 26 against a shoulder thereon. Rotation of the spindle 21 screws its threaded part into or out of a member 18 which closes the movable end of the bellows. Thus the distance of the collar 22 from this member 18 is adjusted. This is achieved by a rotation of the regulating pin 25 by the knob 31 communicated to the spindle 21 which is also free to move axially because a slotted end 23 thereof is slidably connected to the pin 25, in a recess 28, by a wire 24. When the cooling member of an absorption refrigerating apparatus, to which the pilot bulb 13 is attached, cools to a predetermined temperature, the bellows 16 contracts sufficiently for the collar 22 to press on the arm 38 and open the contacts by overcoming the force of a permanent magnet 37 which is mounted on the plate 34 to attract the lever 38 to the circuit-making position. With a rise in temperature the magnet closes the contacts 36, 42. The charge of vaporizable or congealable liquid in the bellows system and the extent of the axial movement of the adjusting spindle 21 is arranged so that the extreme positions of the knob 31 give a "Zero cooling" position (lost motion of the spindle with respect to the collar 22 causing compression of the spring 26) when the contacts are permanently open and a "Maximum Cooling" position when the contacts are permanently closed, irrespective of temperature changes, an extension 19 of member 18 preventing complete contraction of the bellows.
