Patent GB-588283-A (GB)
Title: Improvements in or relating to sulphur-containing lubricants
Filed: 1945-02-07
Abstract: Sulphur-containing lubricating compositions such as straight cutting oils, drawing compounds and tapping pastes are prepared by incorporating in a lubricating oil or grease-base insoluble amorphous sulphur having a particle size below 5 m  and chiefly between 1/2 m and 2 m .  A proportion of soluble sulphur less than is required to saturate the lubricating base may also be present.  The insoluble sulphur or the mixture of insoluble and soluble sulphur is prepared by complete or partial extraction of sublimed flowers of sulphur (as distinct from ground rock sulphur) with carbon bisulphide, dichlorethylene, or mineral or fatty oil. The extracted sulphur is reduced to the required particle size by grinding with lubricating oil (which may be the base in which the sulphur is to be incorporated) at a temperature not exceeding 45 DEG  C.  The sulphur does not separate out in service in the hard crystalline form. According to examples the oil or grease base may be a mineral lubricating oil, or mixtures of solid and liquid vegetable, animal or fish oils, or petroleum jelly; the proportion of sulphur present varies from 0.15 to 7 per cent.  Specification 518,664 is referred to.

Title: Extraction of copper from ores and concentrates
IPC: C25C1/12
Filed: 1976-01-27
Abstract: 1496852 Copper recovery DEXTEC METALLURGICAL PTY Ltd 27 Jan 1976 [14 Feb 1975] 03180/76 Heading C1A [Also in Division C7] Cu is leached or recovered from an ore or concentrate containing Cu and Fe by immersion thereof in an acidic electrolyte containing chloride in an amount between that needed to dissolve any Cu<SP>+</SP> present and saturation, with intimate admixture of the mixture with air or an oxygen bearing gas, at a temperature of 50 C. to boiling, at pH controlled to 1À5-7À0, and at substantially atmospheric pressure. Fe solubilized in the process precipitates as Fe 2 O 3 , any sulphide is reduced to elemental form and the Cu goes into solution. The pH may be maintained with HCl addition or by anodic oxidation of water, in the latter case in the anode compartment of a diaphragm cell on the cathode of which the Cu is recovered. The Cu is alternatively recovered by cementation. A pulsating air stream may be supplied via a porous graphite plate. The electrolyte may be the chloride of NH 4 , Na, Mg, Zn or Mn to which Cu ions may be initially added. The soluble Fe content during operation may be kept below 5 g/l. The extraction of chalcopyrite is best effected at pH 2-2À5 above 70 C. Malachite or azurite may be treated.

Abstract: 722,882. Firearms. AKTIEBOLAGET BOFORS. Feb. 9, 1953 [Feb. 11, 1952], No. 3590/53. Class 92(2). Relates to firearms having two barrels 1, 1<SP>1</SP> so associated that they may be elevated and traversed as a single unit. According to the invention, with each breech ring 2, 2<SP>1</SP> there is associated a catch device for the trigger mechanism, which device is rendered inoperative, to release the firing pin, when its breech ring is in the forward position and its breech block is closed and when either (a) the other breech ring is in its forward position and its breech-block is closed, or (b) a manually operable mechanism is operated. In the construction shown the mechanisms associated with each barrel are of similar construction. Referring to the left-hand barrel 1, its breech-block 3, which moves vertically, is connected to a shaft 5 journalled in the breech-ring 2, the shaft being influenced by a spring in a drum 6 and carrying a segment 7. A part 9 on this segment co-operates with a fixed cam face 10 and a surface on the segment is adapted to move to the left a spring-controlled bar 29 in the breech ring when the breech-block is closed. The bar 29 is associated with one end of a lever 24 pivoting on a bar 23 which, when the breechblock is closed, forms an extension of a spring- controlled rod 19 mounted in the breech-block. The rod 19 is slotted in such manner that, according to its position, it permits or prevents the passage of one arm of a lever 16 co-acting with the firing pin. The other end 25 of lever 24 rests in a recess of a spring-controlled member 26 in the breech-ring, which member, when the breech ring is in its forward position is in line with a spring-controlled bar 36 mounted for sliding movement in a fixed housing 31. This housing is fitted with shafts 32, 33, carrying respectively arms 41, 42 whose ends pivot in recesses of a rod 45, and further arms 35, 39, arranged to contact members 38<SP>1</SP>, 38, which operated as shown in conjunction with the fingers 8, 8<SP>1</SP> on the segments 7, 71. Operation. Assuming that the breech ring 2 is in its forward position and its breech-block closed, then the segment 7 will have moved the bar 29 and with it one end of the lever 24 to the left, thus moving the bar 23 and with it the rod 19 to the left but not far enough to release the lever associated with the firing pin. The further movement may be effected by depressing the rod 45 which, by its connection with the arm 41, rotates the shaft 32 thus causing an arm 34 thereon to move the bar 36.and thus the member 26 and the end 25 of the lever 24 to the left. Such rotation of the shaft 32 and the consequent release of the firing pin may also be effected automatically when the breech-ring 2<SP>1</SP> of the barrel 1<SP>1</SP> is moved to the forward position and its breech-block is closed, the rotation of the shaft in this case being effected by the action of the part 81 of the segment 71 on the contact member 38<SP>1</SP> extending between the segment and the lever 35.

Divided on 412,421, [Group XXXIV]. [Class 99 (i).] A crank-pin is lubricated from a fixed source by a pipe 5a which passes to a rotary joint 1<a> positioned by a flycrank 4a on the axis of the axle lla. The joint la is supported so that it can move horizontally and vertically relatively to the fixed supply of lubricant. As shown in Fig. 1, the joint 1<a> is supported by a bar 2<a> pivoted at its ends to the joint and to the under-frame 12<a>. In a modification, the joint is supported by springs. A check valve 10a prevents loss of lubricant when the apparatus is at rest. A form of rotary joint arranged to convey lubricant to two connecting rods mounted on a single crank pin is shown in Fig. 2. The fly-crank 22 has a pin 6 on which is mounted by a ball bearing 1 a housing 2 having a cap 12. Rings 8, 11, fixed to the pin 6 form with the cap 12 lubricant chambers and a passage a leads from one of these chambers through a nipple 181 to one of the connecting- rods and the other chamber is connected to the second connecting-rod by a passage b and nipple 18. Lubricant is led to the chambers from the fixed lubricator by pipes secured to nipples 23 fixed to the housing 2.

Abstract: 885,639. Electric tests. SCOTT & CO. (ELECTRICAL ENGINEERS) Ltd., JAMES. May 5, 1958 [Feb. 4, 1957], No. 3766/57. Class 37. [Also in Group XXX] Apparatus for testing ferromagnetic articles comprises a first transformer through which passes a conveyer belt carrying the articles so as to vary the mutual inductance of the transformer, a second transformer designed to receive a standard article, and a comparator fed with the outputs of the transformers and arranged to operate a relay in accordance with the comparison. The apparatus may be used for detecting the number of articles in a packet the mass, density, resistivity or effective permeability, &c. of an article, or differences in the effect of heat treatment. In the apparatus shown, packets of razor blades are passed to a conveyer belt 3 by a shoot 2 and carried through a transformer T1 causing a flap 6 to operate and remove the packet when the number of blades is too few. The transformer T1 is one of a pair of transformers T1, T2 which are connected to an oscillator 8, Fig. 2, and which have their secondaries arranged in opposition so that normally substantially no output is obtained from a balancing unit 9. A comparison specimen 1 is inserted in the transformer T2 to unbalance the circuit so that when a correct packet passes through transformer T1 the output is reduced to zero, while an incorrect packet causes the reduction to a lesser value. The outputs are applied to a detector circuit 10 which passes to two trigger circuits 1 and 2, pulses corresponding to the changes in amplitude and having a magnitude corresponding to the number of blades in the package. Trigger 1 is operated only by pulses corresponding to the incorrectly filled packages while trigger 2 is operated by every pulse and opens a gate 13 allowing any incorrect pulses from trigger 1 to pass to a delay circuit to actuate a flap 6 and reject the package. Suitable circuits are illustrated in the Figs. 6 and 7, but not described.
