Title: Improvement in air line oiler
IPC: E21F17/10
Filed: 1928-03-20
Abstract: 296,278. Marks, E. C. R., (Ingersoll- Rand Co.). March 20, 1928. Lubricant conveyed by fluid.-In an air line oiler comprising a casing A, interposed in the pipe line G, L and forming a lubricant reservoir, and a tube P forming a pressure-fluid passageway through the casing, the tube P is rotatably mounted in the ends of the casing and a weight Q is pivoted by arms R, S on a pin W projecting transversely through the tube. An oil passage d leading from the lowermost point of the weight Q through the arm S communicates with a transverse passage h in the pin W by means of passages e, f, g controlled by an adjustable valve k. The arrangement ensures that, whatever the position of the casing A, the inlet of the passage d is at all times maintained in the lowermost part of the reservoir. A transverse passage o in the pin W leads from the interior of the tube P through passages p, q to a pipe r extending above the surface of the oil, whereby, due to pressure fluctuations consequent on the operation of the machine, oil is forced from the reservoir through the passage d into the tube P, whence it is carried by the pressure fluid to the machine.

Title: The 2-hydroxy-4-aminobenzoic acid salts of streptomycin and dihydrostreptomycin
Filed: 1950-04-05
Abstract: The 2-hydroxy-4-aminobenzoic acid salts of streptomycin and dihydrostreptomycin are prepared by reacting a water-soluble or partially water-soluble salt of 2-hydroxy-4-aminobenzoic acid, e.g. barium salt, with an aqueous solution of a streptomycin salt or dihydrostreptomycin salt such as the sulphate.  It is preferred to add 2-hydroxy-4-aminobenzoic acid to an aqueous solution of streptomycin (or dihydrostreptomycin) sulphate and to precipitate the sulphate by the addition of an aqueous solution of barium hydroxide, the filtrate being freeze dried.  The salts are white crystalline compounds soluble in water.  If the inorganic salt formed is more water-soluble than barium sulphate, the resulting aqueous solution is evaporated to dryness and the streptomycin or dihydrostreptomycin salt extracted with an organic solvent such as acetone or ethanol.

Title: Improvements in apparatus for stretching and guiding tubular textile fabric
IPC: D06C5/00
Filed: 1950-04-12
Abstract: 690,283. Finishing fabrics. DUNGLER, J. April 12, 1950. [April 15, 1949; Nov. 18, 1949] No. 9010/50. Class 42 (i). Apparatus for stretching and guiding tubular textile fabric comprises external guide means, loose internal guide means freely rotatable inside the fabric and retaining means arranged externally of the fabric to restrain movement of the internal guide means inwardly of the fabric. As shown, Fig. 2, magnetic rings 6, located inside tubular fabric 9, are held by electromagnets 7 against the grooves of pulleys 3, 4, the fabric being pressed between the rings and pulleys. Rollers 4 are driven to forward the fabric, through gearing 10, 11. The fabric may be stretched longitudinally by taking it up at a speed greater than that at which it is fed by pulleys 4, or by braking pulleys 3. Each pair of pulleys 3, 4 is mounted with its associated electromagnet on a carriage 2 slidable on a support 1 ; carriages 2 are engaged by a lead screw 15 rotation of which, by a hand wheel 17, adjusts the distance apart of the two sets of pulleys. Two such assemblies may be arranged in series, Fig. 5, each pair of rings 6, 6a being' peripherally grooved and connected by an endless belt 29 ; the belts guide and stretch the fabric as it passes between the two assemblies. For restraining inward movement of rings 6, the electromagnets may be replaced by inclined rollers 18, 19, Fig. 3, surfaced with elastic material. Roller 19 can be swung about a pivot 24 for inserting the fabric 9 and clamped in the operative position by means of a handle 25. In another embodiment, pulleys 3, 4 are dispensed with, ring 6 being hollow and being held against inward displacement by rollers 18, 19 and against outward displacement by the fabric itself; carriage 2 carries a supporting surface for the innermost portion of ring 6. The ring 6 may have a peripheral sharp cutting edge for slitting the fabric longitudinally. In a further embodiment, Fig. 10, a pair of rings 43, 44 at each edge of the fabric 9 are journaled on a common support plate 45 and are retained, as in the last-mentioned embodiment, by inclined rollers above, the rings being formed in two halves positioned on opposite sides of support 45. A roller 50, carried by support 45, rests, through the fabric, on a roller 49 mounted on the carriage 2. An extension 52 of support 45 serves to guide the fabric close to a pick-up device 57. A cutting edge 56 may be provided for severing the fabric along its longitudinal fold line. Rings 43, 44 may be interconnected by a steel belt or other linkage. A number (e.g. three) of the assemblies shown in Fig. 10 may be disposed in planes at, say, 120 degrees to each other, to give the tubular article a triangular cross-section and cut the fabric into three portions of equal or different widths.

Title: Improvements in or relating to electric time switches
IPC: G04C23/24
Filed: 1930-03-21
Abstract: 351,415. Time switches; switches partly electromagnetic. HORNBY, R., 7, Carlisle Street, London. March 21, 1930, No. 9122. [Class 38 (v).] As shown diagrammatically in Fig. 10, an electric or other motor 1 drives a time dial 9 carrying a tappet 11 which at a predetermined time closes contacts 13, 14 in the circuit of an electromagnet 17 which thereupon rotates an armature connected by links 27, 28 to a main switch arm 36 causing the latter to engage a stationary contact 37 ; at the same time the movement of the armature opens the contacts 13, 14. At a later predetermined time a pin 18 adjustably mounted on the dial 9 releases the armature, which was automatically looked at the end of its movement, the armature and switch 36 then returning to their original positions under the influence of a spring 30. Fig. 8 shows the manner in which contacts 13, 14 are operated, the cam-shaped tappet 11 first raising two arms 20, 21 and then slipping past the short arm 21 whereupon a pin 23 connected to the arm 21 descends and allows the contact spring 13 to engage the contact spring 14. When the electromagnet 17 is then energized, an arm 39 on its armature engages a pin 39a, Fig. 6, and moves to the left a sliding support 20a on which the contacts 13, 14 and arms 20, 21 are mounted causing the contacts 13, 14 to open immediately. The movement of the sliding support 20a also operates by means of a link 41a a bell-crank lever 41, a pin 40 on which then locks the arms 39 against return. At a later time the pin 18 on the dial 9 engages the lever 41 and releases the arm 39, the armature and switch 36 then returning to their original positions. In order that the electric motor 1 shall run at a constant speed, it is connected, Fig. 10, by means of a coupling 44 with one crown wheel 45 of a differential gear, the other crown wheel 52 of which is also connected to it but through gearing and a spring coupling 51 and an escapement device 53 and balance wheel. In consequence the wheel 52 runs at a constant speed but the speed of the wheel 45 varies slightly as the speed of the motor varies. Any difference in the two speeds causes the planet pinion 58 to rotate and operate a switch 59 which energizes a shunt coil of the motor 1 and reduces speed.

Title: Improvements in or relating to methods of hardening glycerides
IPC: C11C3/12
Filed: 1957-07-05
Abstract: Glycerides are hardened by hydrogenation in solution in a hydrocarbon solvent in the presence of a stationary mass of catalyst over or through which the glyceride solution flows.  The glyceride may be obtained by solvent extraction of oil bearing materials of vegetable or animal origin.  The solvent may be hexane or a benzene fraction. The catalyst may be a metal catalyst, unsupported or supported on a carrier, e.g. silica gel. The catalyst may be a Raney catalyst, and may consist of equal parts of nickel and aluminium; a part of the nickel content may be replaced by copper.  The process may be carried out at an elevated temperature below the boiling point of the solvent, and may be effected under pressure.  In examples, miscellae obtained by solvent extraction, of ground-nut oil, maize oil, soy oil, palm oil, all in hexane, and miscellae obtained by extracting residues of pork fat with hexane and fish waste with a benzene fraction, are hydrogenated by passing the solutions through a column containing Raney nickel, in countercurrent to hydrogen, to obtain hardened fats after removal of the solvent by distillation. German Specification 722,108 also is referred to.
