Title: Safety Coupling for Motor Ploughs.
Inventor: NICHOLSON ALEXANDER
IPC: A01B61/00
Filed: 1917-07-20
Abstract: 117,150. Nicholson, A. July 20, 1917. Couplings for tractors.-Relates to a friction coupling which parts at a limit of stress. In one form, Fig. 4, a pair of loose co-axial bolts 6 in a yoke 1 carries a central drum 5 and an external pair of hubbed disks 3 which are pulled into contact with the ends of the drum by springs 7 round the parts of the bolts within the drum. The disks are prevented from turning by lugs 4 engaging the arms of the yoke, and the contiguous faces of the drum and disks have interengaging ribs and grooves as shown in Fig. 7. The draught-cord being hooked thereon, the drum slips against the disks when the pull overcomes the springs. In another form, the yoke 1 carries bolts at right-angles to those depicted and springs round these bolts press plates 4, Fig. 3, against the arms of the yoke so that bevelled inner facings 6 oppose similar facings 10 on a traction-bar 7.

Title: Methods of and apparatus for pasteurizing
IPC: A23L3/04
Filed: 1930-04-02
Abstract: 350,627. Pasteurizing liquids. DEHN, F. B., 103, Kingsway, London.- (Barry - Wehmiller Machinery Co. ; 4660, West Florissant Avenue. St. Louis, Missouri, U.S.A.) April 2, 1930, No. 10472. [Class 49.] Liquids in containers are pasteurized by passing the containers successively through a preheating, a pasteurizing and a cooling zone, a liquid being circulated through these zones in the direction opposite to that of the containers, by introducing cooling liquid into the cooling zone at a rate sufficiently high to cool rapidly the pasteurized liquid, discharging a portion of the cooling liquid and passing the remainder through the pasteurizing and preheating zones. The liquid is placed in bottles which are inserted in carriers 12 secured to a chain 11 which traverses the treatment tank. The latter has vertical partitions 5, 8, 9, 6, and the bottles are carried by the conveying chain 11 through the tank past the partitions. The cooling liquid, which may be water, is fed to the tank through a spray pipe 13, part of this water being finally withdrawn through pipes 15, 16, having an air vent 18, an excess flow of cold water and a rapid cooling of the bottles in the cooling zone being thus provided. The remainder of the water passes to the pasteurization zone, between partitions 8, 9, where it is heated to pasteurization temperature by steam pipes 10. The water overflows from the tank through pipe 14 after having preheated the bottles in the zone between partition 8 and the end wall 1 of the tank. The supply and removal of water to the cooling zone are controlled by valves 19, 17. The bottles are inverted in passing over the chain-carrying wheels in the tank, causing uniform heating of the contents.

[Class 97 (i).] The claw member E of an intermittent - feed mechanism is rotatably mounted on a normally fixed pivot F, and is oscillated by a crank or eccentric, the film H being caused to move so as to engage the claws during the feed stroke and to disengage therefrom during the return stroke. As shown, the member E is oscillated by a crank B rotating counterclockwise, and the crank shaft A carries cams N<1>, N<2>, engaging in slots M in extensions of the frame of the gate K, to rock the gate about a pivot L and produce the engagement &c. The gate may have a portion curved to suit the motion of the claws, and the film may be held during the return stroke by locking pins O on a fixed aperture plate P or by friction.

Abstract: 401,703. Oil engines. PERKINS, F. A., 17, Queen Street, Peterborough, Northamptonshire. April 14, 1932, No. 10729. [Class 7 (iii).] In an engine having a combustion chamber in the cylinder head communicating with the cylinder through a passage, this passage is inclined to the cylinder axis so that the gases issuing from the combustion chamber strike the piston at an angle, and the fuel-injection .nozzle is located in a side wall of the passage. A cylindrical combustion chamber 14 is connected to the cylinder by an inclined tangentially-arranged passage 15, and the fuel nozzle 17, which is enclosed in a tube 25 in a water jacket 26, directs fuel towards both the combustion chamber and the cylinder, the latter spray facilitating the starting of the engine. The outer part of the combustion chamber is formed by a removable cap 33 and may contain a hot plug or an electric starter plug. In a modified construction, a valve closes the transfer passage 15 until fuel injection commences. The valve may be opened by an overhead rocker or by the pressure in the cylinder at the end of the compression stroke, and means are provided to hold the valve open during the working stroke. Specifications 270,673, [Class 7 (iii), Internalcombustion engines, Carburetting-apparatus &c. for], 365,617, and 366,008, are referred to.

Title: Improvements in or relating to method of recovering durene
IPC: B01D9/00
Filed: 1953-04-21
Abstract: Durene is recovered from a hydrocarbon fraction boiling from 350 DEG to 450 DEG  F. by chilling to a temperature sufficiently low to form a slurry of durene crystals in a mother liquor, filtering off the crystals, warming them to form a melt, chilling to form a second slurry of durene crystals in mother liquor at a second temperature above the first, and centrifuging to recover durene crystals.  The initial fraction may be obtained from crude petroleums but is preferably a hydroformed or cracked product.  A narrower fraction of boiling range 360 DEG  to 395 DEG  F. is preferably used.  The initial chilling may be at -50 DEG  to -120 DEG  F. using a scraped surface chiller.  With durene-rich fractions, say 17-40 per cent durene, the upper part of the range is desirable.  The filtered crystals are warmed to between 115 DEG  F. and the melting point of durene (174 DEG  F.).  The second chilling is at 32 DEG  to 115 DEG , suitably 100 DEG  F.  The mother liquor may be recycled.  Examples illustrate the improved results using filtration as compared with centrifuging in the first stage and vice versa.ALSO:Durene is recovered from a hydrocarbon fraction boiling from 350-450 DEG , preferably 360-395 DEG  F., by chilling to a temperature sufficiently low to form a slurry of durene crystals in a mother liquor, filtering off the crystals, warming them to form a melt, chilling to form a second slurry of durene crystals in mother liquor at a second temperature above the first, and centrifuging to recover durene crystals.

Abstract: 471,558. Cutting plastic substances. WEETMAN, R. G., and GRAY, DUNN, & CO., Ltd. April 16, 1936, No. 10939. [Class 87 (ii)] In a machine for cutting biscuits, cheese, soap, &c. of the kind in which a ram forces the material through a frame of stretched wires and a second ram forces the material through a second frame at rightangles to the first, the first ram 7 is moved back while the second ram 19 moves forward and the second ram is disconnected from its driving mechanism on completion of its stroke and returned with a quick motion by a spring or weight before the first ram starts again. The cutting frames 8 have a series of vertical wires which are tensioned by screws and nuts 11, and horizontal wires may also be provided. The ram 7 is operated by a nut 4 travelling along a lead screw 3. The ram 19 is also driven by a nut 16 on a lead screw 15 and is connected thereto by a fork member 20 which carries pawls 21 engaging projections 18 on the nut 16. At the forward end of the travel of the ram 19 the pawls 21 are opened by a cam surface 23 to release the ram which is rapidly returned by a spring 251. Adjustable covers 30, 31 are provided over the two cutting tables 1, 1<1> to hold down the material being cut and a belt conveyer is provided at the end of the table 1<1> to remove the cut articles. The screw 3 is driven from a motor 41 through a shaft 46 and two bevel pinions 47, 48 either of which can be clutched to the shaft. The nut 4 carries projections 64, 66 which engage stops 65, 67 at either end of its travel and thus declutch the bevel pinions from the shaft 46. The clutch is re-engaged by a handle 58. The screw 15 is driven from the screw 3 by a chain 71. The ram 7 may be coupled to the nut 4 by a lost motion device comprising a pin 6 and slot 80 so that the ram is held by balls 84 and sockets 86 against the cutting frame 8 for a short time. If desired the ram 7 may be rapidly returned in a manner similar to ram 19.
