Patent GB-360237-A (GB)
IPC: C01D9/10
Filed: 1930-12-08
Abstract: In the production of potassium nitrate from potassium chloride and ammonium nitrate in a cyclic process a solution saturated at say 50 DEG  C. with potassium carnallite, ammonium carnallite, potassium nitrate, and magnesium nitrate has added thereto the requisite quantity of potassium chloride and water to obtain on cooling say to 20 DEG  C. a precipitate of pure potassium nitrate, which is separated.  To the mother liquor is then added potassium chloride, ammonium nitrate, and a solution of magnesium chloride or crystals thereof so that on evaporating the resulting solution to the bulk of the initial solution a quantity of ammonium carnallite corresponding to the amount of potassium nitrate obtained is precipitated, and a saturated mother liquor results ready for re-use.  In the second step of the process, the solution of magnesium chloride may be replaced by the anhydrous salt recovered from ammonium carnallite, in which case no evaporation is necessary but water must be added; whilst by using potassium carnallite instead of potassium chloride as well as anhydrous magnesium chloride both evaporation and addition of water may be avoided.  The ammonium carnallite may be treated by known methods to form for re-use in the process, both magnesium chloride and ammonium nitrate.

Title: Manufacture of welded pipe
IPC: B21C37/083
Filed: 1929-12-03
Abstract: 335,459. Air Reduction Co., Inc. Dec. 10, 1928, [Convention clate]. Tubes.-Heavy walled steel or iron tubes, e.g. <3>/32 to “ inch in thickness and, preferably from # to 4 inches inside diameter, are fusion welded at high speed, e.g. 40 to 50 feet per minute, by heating the skelp in passage through a long enveloping heating medium or furnace so as to heat it almost to fusion welding point, e.g. above a bright red heat, and then melting the contiguous edges and adjacent metal on either side of the seam by a group of high temperature flames such as oxyacetylene or other oxy-fuel gas flames. One or more multiple jet flames as described in Specification 162,431, [Class 83 (iv), Metals, Working], may be used. The width of the melt at the top is equal to the thickness of the blank and tapers downward to the bottom. The blanks on emerging from the furnace may attain a temperature of about 2000‹ F. The furnace may contain reducing or inert gases and the blanks, which may be passed therethrough by hand or mechanically, may consist of preformed tubes or flat strips formed into tubes just prior to or after leaving the furnace. If formed after leaving the furnace they are passed through a short re-heating zone before reaching the gas flame. A succession of blanks may be treated by tack welding their ends. The edge regions may be melted by the flames after the edges come into contact or before, in which latter case the melted metal bridges the gap in the joint. The blank a may pass through the furnace 2 and through a tubular guide 15, which prevents action by the air before reaching the welding apparatus. Welding is performed by the gas burner 12 and three sets of power driven rolls are used, one pair 9, which is directly beyond the welding region subjecting the tube to moderate transverse pressure so as to eliminate any depression in the top of the seam, a pair 8 acting as guide rolls the upper roll having a guide fin, and the third pair 10 acting as sizing rolls. The unconsumed reducing gas in the flame enters the unclosed seam and removes scale and oxide. Some of this gas flows into the furnace to contribute to the non-oxidizing atmosphere therein.

Abstract: 888,088. Sharpening knives. BURGESS VIBROCRAFTERS Inc. Nov. 2, 1959 [Nov. 3, 1958], No. 37161/59. Class 60. A knife-sharpener includes a tapered abrasive member, means for grinding a knife blade cutting edge into contact with the abrasive member, and means of reciprocating the member across the edge In the embodiment of Figs. 6 and 8 a conical abrasive member 6 is centrally disposed between two slots 4, 5, provided in a metal insert 3 within the upper portion 2 of the split moulded casing 1 of the sharpener, the knife-blade 12 being inserted in the slots successively to sharpen both sides of the cutting edge. A slotted partition wall 10, together with the outer edges of the slots, holds the blade at the proper angle against the cone. A spindle 8, to the top of which the abrasive member 6 is secured, is slidably and rotatably carried in nylon or like bearings 20, 21, domed lower end 18 of the spindle contacting the armature 16 of a vibration motor 13 comprising a core 13b and coil 13a supplied with alternating current. The armature 16 lifts the spindle and abrasive member against the action of a spring 19 so that during movement of the blade 12 through the slot the member is reciprocated at twice the supply frequency. A second spring 23, adjustable by a screw 25, provides a cushion for the downward movement of the armature 16. In the embodiment of Fig. 12 the motor 13 is inverted, having a stiff spring 46 opposed by a leaf-spring 47 to hold the spindle 8 in contact with the armature 14a. In a further modification, Fig. 10, a single knifelocating slot is used, a pair of abrasive members 38, disposed one on either side in staggered relation enabling both sides of the blade edge to be sharpened simultaneously. The members 38 are rotatably mounted on a yoke 41 secured to the top of a non-rotatable spindle 33 which is subjected to reciprocatory motion by a vibratory motor, as in the other embodiment. The embodiment of Figs. 6 and 8 may be provided with a non-rotatable wedge-shaped abrasive member 6 in place of the conical member shown. In a further modification rotation of the spindle instead of being effected by the to and fro movement of the blade, may be positively "driven" during upward movements of the armature 16 by an off-centre contact between a tang 50, Fig. 15, formed on the top surface of the armature.

A remote control system comprises a low frequency signal amplifier and inductive loop an inductive receiver co-operating with the loop means to render the receiver regenerative and thereby transmit a high frequency signal which is picked up by the loop, in series with which is a tuned circuit resonant at the high frequency the tuned circuit being associated with the con trol means. In the embodiment described an inductive loop 5 surrounds a room, and is con nected to the output transformer of a television or radio set. The control device 13, located within the loop, includes an earphone 11, for listening to the programme. Operation of the switch 12 changes the function of device 13, which is a known inductive receiver by applying positive feedback through windings 10, 8 from output to input, and the receiver radiates an H.F. signal. This is picked up by the loop 5, applied to tuned circuit 4, and the voltage in secondary winding 14 is amplified, rectified and applied as a controlling voltage to terminals 17 to control, e.g. the tuning of the receiver. The switch 19 serves to disable the receiver loudspeaker, and a trap circuit 18 prevents spurious oscillations in valve 1 from producing false control signals.

Title: Improvements in or relating to electromechanical positioning systems employing a transducer
IPC: G01B7/24
Filed: 1956-12-12
Abstract: 843,816. Positioning systems. CANADIAN WESTINGHOUSE CO. Ltd. Dec. 12, 1956 [Dec. 15, 1955], No. 37992/56. Class 40 (1). A positioning system comprises (1) a transducer as in Specification 843,817 or its capacitive analogue, a servomotor for moving the two elements axially relative to one another until the coupling between them is a maximum or a minimum, and means for operating the servomotor in response to electrical energy derived from the second element as a result of energy supplied to the first. In Fig. 4 A.C. is fed via slip rings 31 to the first bifilar helical element 30 which is rotatable by a calibrated knob 31<SP>1</SP> but is fixed axially. The second element 33 comprises a short helical pick-up coil which can be driven axially by a servomotor 36 via a rack and pinion. The position of the second element generates a corresponding voltage in the unit 37 which is compared at 39 with a voltage manually pre-set by the coarse adjuster 41, and any difference energizes the servomotor via a switch 40 to move the element in the direction which reduces the error voltage. When the latter falls below a certain value the switch 40 (circuit in Fig. 5, not shown) disconnects the comparator 39 and connects the servo motor directly to the output of the element 33. The final position of balance then depends on the setting of the fine control 31<SP>1</SP>. The capacitative form of transducer appears in Fig. 3 where an alternating potential is applied at 45, 46 and picked off at 47, 48. Specification 604,382 also is referred to.
