Title: Hydraulically driven pipe-bending machine
IPC: B21D7/02
Filed: 1955-01-21
Abstract: 791,284. Angular bending. HILGERS MASCHINENUND APPARATE-BAUANSTALT GES. Jan. 21, 1955 [Jan. 22, 1954], No. 1911/55. Class 83 (4). A pipe-bending machine with an hydraulically-operated bending member, the return stroke of which is more rapid than its bending stroke, has in the hydraulic pipe line a throttle valve which controls the speed of the working stroke and, in a line by-passing said throttle valve, a shut-off valve which is closed during the working stroke but open during the return stroke so that the flow of hydraulic fluid during the return stroke is unhindered by the throttle valve. A bending former, to which a pipe to be bent is secured, is rotated by a piston 10 in a cylinder 11. Hydraulic fluid from a pump 12 passes through a valve 14, directing the fluid to one side or other of a piston 10, through a pipe line 15 to a cylinder 11 to move a piston 10 to the left for a working stroke of the bending former. Fluid passes from the left-hand side of the cylinder 11 through a line 16, adjustable throttle slide valve 18, valve 14 and line 17 to a reservoir, the throttle valve 18 thus controlling the speed of the piston 10 as it moves to the left. At the end of such movement a switch 20 is actuated to reverse the valve 14 and open a shut-off. valve 21 in a line 23 by-passing the throttle valve 18. The piston 10 is thus returned rapidly to the right until it actuates a switch 24 to bring the valve 14 in a position to stop the machine, the shut-off valve 21 being then, or at the latest when the machine is once more switched on, closed.

Filed: 1929-01-19
Abstract: 320,581. Abbott, A. B., and Abbott, R. Jan. 19, 1929. Dipping-rods.-The presence and quantity of water lying below the oil in an oil tank is determined by means of a dip-stick coated with a mixture of at least two ingredients one of which is impervious to or unaffected by oil but soluble in water, and the other of which is absorbent to water. The water absorbent facilitates the solution of the water soluble ingredient where it is in contact with water, so that the level is clearly shown when the stick is withdrawn. A binder is preferably added also, to retain the soaked absorbent on the rod, and a preservative to prevent access of moisture from the atmosphere. The oil-impervious, water-soluble ingredient may be treacle, heavy syrup, molasses, or honey, the water absorbent may be chalk or charcoal, the binder may be jeweller's rouge, and the preservative may be turpentine. Colouring ingredients such as sulphurated potash and tincture of ferric chloride (British Pharmacopoeia) may also be added.

Title: Production of acyclic acetone peroxides
Inventor: HIGASHIUCHI KAZUO
IPC: C07C409/22
Filed: 1963-01-16
Abstract: Acyclic organic peroxides, consisting essentially of 2,2-dihydroperoxy-propane and bis-(1,11-hydroperoxy-1,11-methyl)-diethyl peroxide in a weight ratio of at least 3: 1, are prepared by mixing acetone, hydrogen peroxide, water, and 0.15-15% by weight of phosphoric acid and maintaining the resulting reaction mixture at a temperature of from - 20 DEG  to 35 DEG  C. for from 6 hours to 10 minutes, depending upon the proportion of catalyst and the temperature employed. The molar ratio of hydrogen peroxide to acetone for the total acetone employed is from 1.5: 1 to 6: 1 and the water employed amounts to 5-95% of the reaction mixture. The yield of organic acyclic peroxides amounts, in hydrogen peroxide equivalents, to at least 60% of the hydrogen peroxide employed as starting material. Examples are given.  Comparative examples describe the use, as catalysts, of nitric acid and sulphuric acid.ALSO:An organic acyclic peroxide bleaching and maturing composition consisting essentially of 2, 2-dihydroperoxy-propone has a flour-bleaching capability more than 33 per cent greater than one wherein the organic peroxide content consists essentially of bis-(1, 11-hydroperoxy-1, 11-methyl)-diethyl peroxide, and at least 33 per cent greater than one containing both the above peroxides with a weight ratio of the former to the latter of, for example, 2:1.  The preparation of compositions in which this ratio is at least 3:1 is described (see Division C2).
Patent GB-490127-A (GB)
Title: An improved process for thickening unsaturated oils
IPC: C10G32/02
Filed: 1938-01-21
Abstract: A process for increasing the viscosity of unsaturated oils consists in separately hydrogenating the oil and then subjecting the hydrogenated oil to voltolization.  Natural unsaturated ester oils having a chain of more than 8 C atoms and an I value of above 110 are preferred.  The hydrogenation process prevents the formation of insoluble jelly-like products during voltolization. The hydrogenation may be carried out at temperatures of 200-450 DEG  F. in the presence of an Ni catalyst, at atmospheric or raised pressure.  In an example, menhaden oil of 180 I value is hydrogenated in the presence of a Ni catalyst till the I value is reduced to 100.  The hydrogenated oil is voltolized in a trommel-type voltolizer at 4-6 cm. of mercury absolute and an electric potential of 4,000 volts at a frequency of 10,000 cycles per second.  When an oil of viscosity of about 600" Saybolt at 210 DEG  F. is produced, a petroleum lubricating oil of viscosity of about 70" Saybolt at 210 DEG  F. is added and the mixture further voltolized till a final product having a viscosity of 1000" Saybolt at 210 DEG  F. is produced, free from any jelly-like products insoluble in water.  The products may be used alone as lubricants or added to lubricating oils, greases, soaps &c., as oxidation inhibitors or pour point depressants.

Title: Improvements in or relating to vibration damping devices
IPC: B42D15/00
Filed: 1935-01-22
Abstract: 444,222. Vibration-dampers. SARAZIN, R. R. R., St.-Prix, Seine & Oise, France. Jan. 22, 1935, No. 2107. [Class 108 (iii)] In a vibration-damping device comprising a mass movably supported upon the vibrating part by one or more rolling members, each of which rolls on a track carried by the vibrating part and on a track carried by the mass, the rolling member is a circular or non - circular cylinder and rolls with its outer surface on the roll. ing tracks of the vibrating part and of the movable mass respectively. A disc 2 secured to a shaft 1 has slots in which is mounted a weight 3 having pins 5 of smaller diameter than recesses 6 in the disc 2. The pins 5 and recesses 6 are formed with cylindrical bearing surfaces 7, 8 on which run rollers 9 which form the connecting members between the shaft 1 and weight 4. A weight 11 mounted in a recess 10 in the weight 3 and urged by a spring against the disc 2 prevents relative motion between the weight and the shaft at low velocities. The weight 11 moves outwardly when the shaft 1 rotates at high velocity thus freeing the weight 3 for movement relative to the disc 2. In a modified construction, Fig. 5, a member 2, attached to the shaft 1 has spaced lugs between which the ends of the weights 3 are mounted. The central part of the roller 18 rolls on a hardened sleeve 17 mounted in the weight and each end portion of the roller has a bush 19 on which is freely rotatable a sleeve 20 which rolls on a hardened sleeve 15 mounted in a recess 14 in the lug. To prevent jamming at low velocity each weight is provided with two studs of which the ends are adjustably set near the surface of the member 2. In a modification of Fig. 5, Fig. 6 (not shown), each rolling member is provided with toothed rims secured to the roller by a key and shrunk on to the central portion of the roller. A central toothed rim co-operates with teeth formed on an annulus secured to the added weight. For damping longitudinal vibrations in a crank-shaft, the disc 2 is supported on the crank-shaft in a plane passing through its longitudinal axis, and the mass 3 vibrates in a direction parallel to that plane. The rolling member may have a non circular cross-section and the rolling tracks may be other than circular and of different curvatures. Lubrication is effected from an axial bore 23 associated with a passage 24 in a bolt 25 and connected to a passage 26 in the member 2.

Title: Automatically-Retractive Key Holder
Inventor: RIVERS ELDEN LELAND
IPC: A45C11/32
Filed: 1968-01-15
Abstract: 1,171,433. Key holder. E. L. RIVERS. 15 Jan., 1968, No. 2196/68. Heading A4G. A key holder for automatically withdrawing a key from a lock is formed of a hollow cylinder 33 closed at the end having a chain hole 34 and with a bulbous part 30 diametrically slotted at 36 at the open end 35. A flattened finger annulus 45 slides over cylinder 33 until projections on part 30 engage grooves 50 permitting limited rotation of annulus 45. A plunger 38 slotted at 40 up to a bridge at one end and a spring 36 are held in the hollow cylinder by screws 43 passing through annulus holes 46 and short circumferential cylinder slots to enter the plunger slot 40 and abut the end bridge, plunger splines 41 entering slots 42 in part 30. A key has its head secured in slots 40 and 36 by screws 37 biting into the head through holes in part 30, the key blade then extending along plunger 38 in slot 40. Weakened end portions 44, 44<SP>1</SP> may be snapped off the plunger to accomodate different lengths of key blade and allow a small end portion of the blade to protrude. When the key blade is inserted in e.g. an automobile ignition cylinder lock the plunger is forced into cylinder 33 compressing spring 36. On turning the key in the lock, annulus 45 rotates slightly and engages screws 43 in plunger notches 48 to prevent spring 36 ejecting plunger 38 and possibly forcing the key out of the lock. On turning the key to switch off ignition, screws 43 leave notches 48, plunger 38 is ejected and forces the key out of the lock. In a modification, one screw 37 is used and may replace the splines 41 and slots 42.

Title: Improvements in the process of and mechanism for knitting caps and the like
IPC: D04B1/24
Filed: 1932-01-26
Abstract: 387,501. Circular knitting- machines. HADDAN, R., 31, Bedford Street, Strand, London.-(Ainslie Knitting Machine Co., Inc.; 740, Grand Street, Brooklyn, New York, U.S.A.) Jan. 26, 1932, No. 2382. [Class 74 (ii).] In the production of knitted caps solely by reciprocation the needles are divided into a hat band group H with long butts, and into two other groups E, C with medium butts. Needles are omitted from one sector between the crown and hat band groups C, H. An extra needle B at the gap end of the group H with a long butt, but no head normally prevents narrowing at the hat-band end of the work. The left-hand up pick 651 lies in the path of the medium butts, but the right-hand up pick 650 is not long enough to do so. The down pick 680 is notched to receive long butts on one side only. Long butts meeting it in a clockwise direction and medium butts meeting it in either direction are not lowered. A switch cam 415 lowers needles as a group to the active level. The stop 506, Fig. 6 (not shown), prevents the cam 415 from ever raising needles out of action as a group. When it is required to knit the looper courses the up picks 650, 651 are thrown out of action. When narrowing at the hat-band end is required the down pick is placed out of action. The effect of the up pick on the needle B is then no longer nullified and narrowing can take place. A dished guard 503, Fig. 10 (not shown), extending most of the way round the cylinder tends to restrain the formed fabric from rising up. Specifications 12722/13, [Class 74 (ii), Knitting &c.], and 386,448 are referred to.

Abstract: 607,335. Automatic voltage control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1946, No. 3017. Convention date, Feb. 1, 1945. [Class 38 (iv)] In a system for regulating the voltage of a dynamo-electric generator, electrically-operated means responsive to generator speed, but independent of the electrical condition of the generator reduce the correction necessary by the voltage regulator over the speed range of the generator. The terminal voltage of a D.C. shunt generator 1 driven by an aircraft engine 2 is maintained constant by a field rheostat 4 automatically adjusted by a control coil 3, the energization of which is dependent on the terminal voltage. Should the speed of the aircraft engine, and hence the generator speed, exceed a predetermined value, the operation of a relay 7, energized from a tachometer alternator 9 through a high-pass filter 10, inserts a resistor 12 in series with rheostat 4 to extend the range of regulation. Reverse operation of relay 7 to short-circuit resistor 12 occurs at a lower speed than forward operation to ensure positive operation of relay 7.
