Title: Radiation polymerisation of unsaturated ethers
Inventor: PINNER SOLOMON HARRIS
IPC: C08F16/12
Filed: 1957-09-11
Abstract: Unsaturated ethers of the formula R-O-CR1 =CH2, when R and R1 represent alkyl, alkenyl, or aryl groups or substituted alkyl, alkenyl or aryl groups except that R1 may be a hydrogen atom only, and R and R1 may be the same or different, are polymerized by exposing the ether, optionally in the presence of solvents, zinc oxide and other metal oxides, silica or organic polymers, to the action of high energy ionizing radiation, whilst maintaining the mix at a temperature of from -50 DEG -100 DEG C., and without the application of external pressure. Specified ethers are ethyl vinyl ether, n-butyl vinyl ether and isobutyl vinyl ether.  The radiation may be produced by high energy electrons, X-rays, or gamma rays, particularly those emanating from a cobalt 60 source.  A low dose rate not exceeding 10,000 rods per minute is preferably used, and the total dosage of radiation may be between 1 and 20 megarads.  The product may be used in adhesives, tackifying agents and pressure sensitive tape formulations.

IPC: B03B5/24
Filed: 1933-10-18
Abstract: 427,259. Washing granular materials. NORTON, B., Sandford Hall, Claverley, near Wolverhampton. Oct. 18, 1933, No. 28884. [Class 82 (ii)] A jig washer for coal and the like is provided with means which as the depth of the refuse bed varies, automatically arrest or release the flow of refuse through a discharge opening and with separate means for retarding the flow of refuse outside the discharge opening when the flow has begun. In the form shown coal &c., is fed by a shoot 2 into a washer box 1 and is stratified by pulsations of water through a screen 3. Refuse passes through a discharge opening 4, adjustable by means of a sliding gate 5, on to a shelf 6, the flow of refuse through the opening 4 being arrested or released by a weir 7 pivoted at 8 and controlled through a relay mechanism by a float 9. The flow of refuse over the shelf 6 outside the discharge opening 4 is retarded by a flap 10 hinged at 11 which rests on the refuse, the free end of the flap being connected by a rod 12 to a pivoted lever 13 provided with a balance weight 15 so that the pressure of the flap of the refuse can be adjusted. The rod 12 passes through a tube 16 in the coal inlet shoot 2 and a bracket 17 on which the lever 13 is pivoted is fixed to the tube 16. The downward movement of the flap 10 is limited by a collar 18 on the rod 12 which engages the bracket 17 and the upward movement of the rod 12 is limited by the provision of an adjustable stop 19 carried by the bracket 17. Instead of the pivoted flap, an air chamber fitted with shifting valves may be used for controlling the movement of the refuse over the shelf and means other than the combination of a shelf and weir may be used to effect the arrest or release of the flow of refuse through the discharge opening. Specification 304,012, [Class 82 (ii)], is referred to.

Patent GB-410741-A (GB)
Title: Improvements in or relating to the conversion of high boiling point hydrocarbons into lower boiling point hydrocarbons
IPC: C10G11/02
Filed: 1932-10-19
Abstract: High-boiling hydrocarbons are converted into low-boiling hydrocarbons by dispersing therein one or more double halogen salts preferable with the addition of oxidizing agents and heating the mixture at atmospheric pressure to 10--30 DEG  C. above the boiling point of the hydrocarbons thereby causing a vigorous halogenation of the mixture with evolution of hydrogen.  Suitable double salts are the double chlorides, fluorides, and bromides of the alkaline and alkaline-earth metals and of boron, phosphorus, antimony, tin, magnesium, and aluminium.  Activators such as iodine and anhydrous copper halides may be added and oxidizing agents such as manganese dioxide, lead chromate, chromic oxide, and copper oxide.  Aromatic compounds are obtained by first saturating the mixture with acetylene and then adding the double salts and activators with traces of finely subdivided iron or nickel.  The oxides of the double salts obtained in the residues are reconverted by heating them in the gas current containing halogens produced in the reaction passed through a retort lined with bauxite or alumina bricks.  The liquid residues after filtration and treatment with decolorizing agents yield lubricating oils.  A fuel oil is saturated with acetylene and mixed with 8 per cent of a mixture of aluminium-antimony, cupric-ferric, and magnesium-titanium double chlorides together with 1 per cent copper oxide, 5 per cent manganese dioxide, and 0.5 per cent nickel.  The mixture was heated to 280 DEG  C. and 53 per cent distilled over and on redistillation gave 14 per cent benzols and 20 per cent unsaturated compounds.  The residual liquid after treatment with decolorizing agents and calcium oxide gave a lubricant having a viscosity of 5 DEG  (Engler) at 50 DEG  C.  Further examples are given of the treatments of paraffin oil, and a used lubricant.ALSO:Aromatic hydrocarbons are obtained from liquid acyclic hydrocarbons by saturating them with acetylene, dispersing therein one or more double halogen salts, preferably with the addition of oxidizing agents, and heating the mixture at atmospheric pressure to 10--30 DEG  above the boiling point of the hydrocarbons, after addition of a trace of subdivided iron or nickel.

Title: An improved construction of fluted rolls for cutting grain
IPC: B02C4/30
Filed: 1925-11-23
Abstract: 243,721. Schaefer, J. Nov. 25, 1924, [Convention date]. Addition to 234,504. Roller mills.-Relates to fluted rolls for cutting grains into halves for use in the process claimed in the parent Specification. The lower roll is so fluted that a grain lies in a groove between two flutings, and the cutting or upper edge of a fluting or tooth co-operates with the edge of a fluting or tooth of the upper roll. The height of the teeth is such that the halves of grain project beyond them and the grains are cut into halves by oppositely-located teeth. As shown, Fig. 1, the teeth b of the upper roll are spaced at twice the distance apart of the teeth e of the lower roll, the peripheral speed of the upper roll being twice that of the lower roll. The diameters of the rolls and the depths of the grooves are so proportional that when the edges of the teeth engage with both sides of a grain held transversely in a groove, the bottoms of the two grains are spaced apart from one another by the diameter of the grain, so that the latter is held without play between the sides of the teeth and the bottoms of the grooves. The teeth may be small and symmetrically arranged with two sharp edges, as shown in Fig. 2.

Cylinder machines.-Machines for moulding lintels, fenceposts &c. consist of an intermittently rotating drum 1 containing mould boxes 2 and adapted to be actuated by a reciprocating rack 24 which is also arranged to drive a conveyer 22, Fig. 1, for removing the moulded articles. The moulding operation comprises part-filling and reinforcement-placing at one point of rotation of the drum, complete filling after rotation through 90‹, pressing during rotation through the next quarter of a revolution and removal on to the conveyer after rotation through another 90‹. The mould boxes 2 are bottomless and have extensions 51, Fig. 3, at their ends which engage in slides 52 in a casting fixed to the drum. Rollers 54 on the extensions 51 engage in a cam-track 55 on the fixed shaft 61. A press 56 works in each mould box and has a conneoting-rod, of which a roller is arranged to work in a second cam-track. The two cam-tracks are of such form that pressure is applied during the second period of rotation against a reaction bar 17 which rotates with the drum in a slide 18 for a part of a revolution and then returns to its initial position. The mould boxes and presses move outwardly during the third period of revolution, at the end of which the block &c. is received by a pallet 16. The secondary shaft 30 is provided with two cams 21, 32, as in Fig. 9; one cam 21 operates a pair of pivoted levers 19 carrying the palletlifting member, and the cam 32 is arranged to lift the mould box after removal of the block &c. by means of a pivoted lever 70. The rack 24 is reciprocated from the shaft 30 by means of a connecting-rod 31 and is adapted to transmit intermittent one-way motion to the drum 1 by means of pawl-and-ratchet gearing on a shaft 35 and pinion gearing 36, 37. A chain 38 from the shaft 35 is arranged to operate the tampers 6 for complete filling of the mould boxes, through the medium of a crank and connecting-rod 41 on a shaft 40, and a second chain drives the partfilling and reinforcement-placing ram 7 in a similar manner. A tamper 5 for forcing the material in front of the ram 7 is operated by a crank and connecting-rod from the drum gear 37. The conveyer 22 receives intermittent motion from the rack 24 by means of a pawl-andratchet gear, and is provided with cleats 64, each of which is arranged to remove a pallet from the magazine 65. Reinforcement bars are also placed in front of the ram 7, being dropped behind a shutter 9 which receives vertical movement through the medium of a rod 11 by a cranked lever 10, as in Fig. 8. The lever 10 is engaged by stops 12, 13 on the reciprocating rack 24. The reinforcement conveyer 8 is operated by the rod 11, through a rack 14 and a pawl-and-ratchet gear. Nibs 45 are provided on the ram 7 to support the reinforcing rods. The main drive of the machine is through pulleys 26, main shaft 27, worm 28, worm-wheel 29, and shaft 30.

Filed: 1937-11-01
Abstract: 497,167. Decorticating flax &c. DEHN, F. B. (Ittner, M. H.) Nov. 1, 1937, No. 29857. [Class 120 (i)] In a machine for decorticating flax and like stalks, the stalks are bent backwards and forwards as they are passed lengthwise through the machine by members engaging the stalks and moving with generally circular motion within planes perpendicular to the direction of feed, the stalks being simultaneously rubbed back and forth transversely of their general direction of movement. The means for bending and rubbing the stalks comprise blades 12 ... 28, Figs. 2 and 3, arranged in substantially parallel sets having relative motion crosswise and lengthwise of the blades. Alternate pairs of blades 12, 14, 16, 18, 20, 22, 24, 26, 28 are stationary while the remaining blades are movable to co-operate therewith in treating the straw. The blades are divided into two groups by the central blades 18, and the movable blades 13, 15, 17 of the first group are moved upwardly while the movable blades of the second group are moved downwardly. The blades are also moved longitudinally of the stationary blades to effect a transverse rubbing action on the stalks through crank shafts 29, 30 each of which includes two cranks at 180 degrees. The ends of the movable blades are mounted in recesses in blocks 31, and are secured by bolts 33, Fig. 5. The blocks 31 are connected directly to the cranks and at one end allowance is made by a sliding connection, which may be provided with springs, for expansion or distortion of the blades. The crank shafts 29, 30 and the fixed blades are supported by brackets 40, 41 and the crank shafts are connected by a sprocket chain 45 the shaft 29 being driven by a belt 47 engaging a pulley 46. A second pulley 46a may be provided on the shaft 30. The fixed blades are connected by rods 48 and by screw-threaded rods 49, carrying spacing washers 54. The blades at the entrance side of the machine are made stronger and are the more widely spaced. The stalks are fed from a shoot 11 having a narrowed exit and are discharged through a shoot 56. When the lower movable blades at the entrance of the machine are rubbing the material in one direction the upper movable blades at the outlet of the machine are rubbing the material in the opposite direction. Immediately afterwards the respective upper and lower sets come into operation and the cycle of operations is continued.

Title: Improvements in cutting machines for corduroy velvet cords and similar fabrics
IPC: D06C13/08
Filed: 1922-11-02
Abstract: 211,191. Varley, F. Nov. 2, 1022. Pile, cutting; stop-motions.-In a machine for cutting the pile of velvet, corduroy, &c. cords in which each cord is cut by a disc cutter v revolving in a longitudinal slot in a guide needle u, which guide passes into and raises the ribs of material to the knife, an electric stop motion operates if the guide should penetrate the material upwards or downwards or if it should foul the material and thereby be forced back bv it in its travel. Insulated bars c, a are fixed across the machine one above and one below the material, while a third insulated bar d passes over the hammers 2 which push forward and keep the guide needles u in position. The rest of the machine is earthed. In operation, when a guide needle penetrates the material and so makes electrical contact with bars a or c or when a guide needle fouls the cloth and is pushed back and so flies up over its hammer 2 into contact with the bar d, then the solenoid g is energized and' attracts the support e, the lever f drops causing the lever h to pivot about the point 9, and the lower end of the lever f operates the pivoted rod 10, Fig. 2, which pushes the shipper 4 out of the notch 5 and allows a weight 11, Fig. 1, to pull it into stopping position where it moves the belt fork 8 over the loose pulley j. In this movement the shipper 4 engaging a collar 6 draws the plunger 0 from between the poles k, l, p, q and breaks the circuit, thus preventing the material from being destroyed by the current. The current is led to poles k, l of a 4-pole switch of which pole q is earthed, pole p is connected to the electromagnet g, and a wire connects g to the insulated bars a, c, d. To start the machine the shipper is moved by its handle n into the notch 5 pushing with it the plunger 0 to connect the poles thus resetting the electrical device. The guides u are arranged irregularly in advance of each other to equalize the strain on the material.
