In a modification, the vice comprises a bridge 39a, Fig. 1A (not shown), fixed to the jaw 39, and screw 43a is screwed into the bridge, but is not screwed into the housing 21. The position of the jaw assembly is indicated by indicia 39b and an arrow 21a. Carriage 13 comprises a cylindrical block 50, Fig. 5 (not shown), slidable on rods 47, and having a square recess 53 into which the die 54 is secured, Fig. 11 (not shown). Lubricant is supplied to the die from a reservoir 57, Figs. 12 and 9 (not shown), into a passage 62, and passes via a plunger 60 into a passage 63, the plunger being actuated to supply the lubricant only during the screwing operation by a lever 65 carried by the rotatable block 50 when the lever engages a roller 70 carried by a rod 71. Rod 71 is journalled in a casing 19, Figs. 1 and 2 (not shown), and extends into a switch-box 23, and a control block 80, Figs. 3 and 16 (not shown), is adjustably secured on the rod. A pin 82 coacts with the handle 85 of a toggle switch, and a slide 105 has a slot 106 which also co-operates with the handle. A casing 110 is detachably connected to grooves 7 in the ends of rod 47 by bayonet slots 113, Figs. 5, 7 and 8 (not shown), and a locking lever 130 and a piston 114 in the casing is urged against the die by a spring 117 actuated by a cam-and-pin assembly 123, 124 controlled by a handle 122. In operation, a pipe is clamped in vice 21, die 54 is urged against the pipe, slide 105 is actuated to operate switch handle 85 to thus start motor M, and the die is rotated to screw the pipe. Switch handle 85 is automatically actuated at the end of the screwing operation, the motor is reversed, and the die is unscrewed from the pipe, handle 85 is again actuated and the motor stops.

Patent GB-838989-A (GB)
Title: Diphenylamine process
IPC: C07C209/64
Filed: 1957-09-17
Abstract: The invention comprises a vapour phase process for the preparation of diphenylamine from aniline in the presence of a catalyst such as aluminium oxide or titanium dioxide where the reacted gases are cooled to a temperature at which diphenylamine condenses out, and then further cooled to condense the aniline, the temperature of this latter condensation step being kept sufficiently high to volatilize the majority of the water present in the stream, together with some aniline.  The dehydrated liquid aniline is removed from the liquid, and a mixture of aniline and water removed from the vapours.  The catalyst may be periodically regenerated by burning out combustible impurities with air which is dehydrated at least to the point where, on re-use of the regenerated catalyst, substantially no water is desorbed to the reaction gas stream.  In an example, aniline containing not more than 500 p.p.m. water is reacted in a D.P.A. converter at 480 DEG  C. and approximately 100 p.s.i.  The vapours from the reflux drum in the aniline condensing zone are passed through a water separation equipment, and the aniline recycled.  The example also describes a process in which the water is not removed. Another example describes the regeneration of the catalyst at 480 DEG C. with air having the following dew points: -47 DEG  F., -10 DEG F., 80 DEG  F. and 84 DEG  F.

Patent GB-409278-A (GB)
Title: Improvements in the manufacture and production of high quality asphalts
IPC: C10C3/08
Filed: 1932-10-20
Abstract: Asphalts are recovered from oily substances containing them by precipitation in stages with different substances having successively increasing precipitating power.  The precipitating agents consecutively used preferably consist of hydrocarbons of decreasing molecular weight, for example heavy oil, middle oil, benzine and liquefied gaseous hydrocarbons such as pentane, butane, propane or ethane.  The liquefied saturated hydrocarbons may be mixed with or replaced by liquefied unsaturated hydrocarbons.  The asphalt-containing raw materials may consist of crude petroleum, or distillation, cracking or destructive hydrogenation residues obtained from coal, tars or mineral oils. In examples: (1) a petroleum residue is heated to 50 DEG  C. under pressure with liquefied butane.  After standing the precipitated asphalt is separated off and the mixture of butane and oil is mingled with a mixture of propane and ethane, when a further amount of asphalt is precipitated; (2) a residue obtained in the destructive hydrogenation of brown coal is treated in successive stages with illuminating oil, benzine and liquefied propane, the asphalt precipitates and the precipitating agent being separated from the oil at each stage.  The asphalts obtained differ in physical properties and may be used in the preparation of electrical insulations, anti-rust agents and road surfacing compositions.  The oils may be purified simultaneously by adding to the precipitating agents sulphur dioxide, phenol, aniline, nitrobenzene, furfurol, ketones, dichlorethane, aceto-nitrile or benzo nitrile or these reagents may be used with the asphalt-free oil.  The purified oil may be used as a lubricating oil and improved by treatment with hydrogen under elevated temperatures and pressures in the presence of a catalyst.  Specification 365,046 is referred to.

In the closed position, Fig. 4, the legs 18 are yieldingly held straddling the bag by a rounded part 33 on the pawl 32 engaging the shoulder 29. Very short legs or studs 40 are provided at the closed end of the bag. According to the Provisional Specification the shoulders 37 can be dispensed with, the pawl 32 then engaging in a slot in the boss 24 to prevent further outward movement of the legs 18.

Abstract: 210,173. Anderson, Boyes, & Co., Ltd., and Guthrie, H. H. Oct. 28, 1922. Reversing - gearing. Gearing for mining machines of the type drawn by a rope or chain, is provided with means for effecting speed reduction between the motor and the machine-feeding element and for effecting less speed reduction for quick traversing. In one arrangement, one primary wheel, Fig. 1, of a differential gear is connected to a wheel 2, engaging a pinion 3 slidable on the driving shaft 4. The pinion 3 carries teeth engageable either with teeth on a non-rotary member 5 or with teeth on an extension 6 of a pinion 7, keyed to the shaft 4. The pinion 7 drives through an idler pinion 7<1> a wheel 8, loose on the hub of the other primary wheel 9 and having a clutch face engageable by a friction clutch 10 feathered to the wheel 9. To drive the feeding shaft 11 at low speed, the pinion 3 is moved to engage the pinion extension 6 and the clutch is engaged. For a higher speed, the pinion is moved to engage the member 5, so holding the wheel 1 against rotation. To disconnect the feeding shaft 11 the clutch is freed. Figs. 3 and 4 show a modification in which the driving pinion 12 engages a pinion 13 secured to a sleeve 14 which is embraced by a sleeve 15 secured thereto and carrying part 16 of a friction clutch. Feathered to the sleeve 14 is the movable element 17 of a dog clutch engageable with teeth on either of pinions 18, 19, connectible through separate trains including idler pinions 18', 19<1>. with a wheel 20. The latter is keyed to a wheel 21 of a differential gear, of which the wheel 22 is keyed to a wheel 23 meshing with a pinion 24 which rotates with the other part 25 of the friction clutch. When the clutch is engaged, the wheels 20, 23 are rotated at different speeds in opposite directions depending on the train leading to wheel 20. The spider 27 rotates in the direction of the faster of the two wheels 20, 23 and so drives the feed-actuating wheel 28 either at a given speed in one direction or at a less speed in the opposite direction.
