Patent GB-493726-A (GB)
Title: Improved process for obtaining valuable polymers from hydro-carbon gases
IPC: C07C2/06
Filed: 1937-05-21
Abstract: Olefine mixtures are polymerized to produce dimers and higher polymers, the latter being separated from the dimers, depolymerized, and then repolymerized.  In particular, butene mixtures are treated with an acid catalyst to polymerize selectively the isobutene into dimers and trimers, the trimers being depolymerized to isobutene which is either repolymerized with acid to gasoline type polymers or with halides at low temperatures to yield polymers of high molecular weight.  A gas containing hydrocarbons from methane to pentane is rectified, preferably under pressure, an intermediate cut, mainly butanes, being collected and passed through a heated coil and, if desired, also through a chamber containing cracking and/or dehydrogenating catalysts.  The butenes produced pass through a condenser and gas separator to a polymerizer where they are sprayed into sulphuric acid of, say, 60-65 per cent at 80-150 DEG  F. to polymerize selectively the isobutene into dimers and trimers.  The product is fractionated, the overhead cut being recirculated, if desired, after removal of n-butenes.  Dimers are withdrawn intermediately and hydrogenated to yield a gasoline blending stock. Trimers pass through a heating coil and, if desired, a chamber containing, e.g. activated clay to regenerate isobutene which is repolymerized to give further gasoline or treated below -20 DEG  C. with, e.g. boron fluoride.  The temperature can be maintained by mixing with liquid butane or propane which is allowed to vaporize. The high molecular weight polymers are blending agents for lubricating oils.

Title: Finger units for root crop separators
IPC: A01D33/08
Filed: 1975-04-08
Abstract: 1498109 Root crop separators ROOT HARVESTERS Ltd 12 Feb 1976 [8 April 1975] 14270/75 Heading B2H  A finger unit for a root crop separator comprises a housing 4, a finger 6 pivotably mounted at 56 in the housing and fitting across a chamber therein with a portion 64 of the finger cooperating with a piston 32, and an inlet for compressed air to the chamber, the arrangement being such that flow of air out of the chamber is confined to clearances between the finger and the' housing. In use the finger portion 6 is normally inclined at 45‹, it being held in this position by means of compressed air supplied to the space above the piston 32 through a passage 44. When an X-ray sensor detects the presence of a stone or clod of soil in a stream of falling material comprising potatoes, stones and earth, the finger is moved out of the path of the falling stream to the position shown. On receipt of the signal from the X-ray sensor, a solenoid valve 8 disconnects the passage 44 from the compressed air manifold 10 and brings it into communication with a passage 48 leading to the chamber so that the air is exhausted from above the piston 32. This enables a spring-operated piston 36 to move the finger 6 to the retracted position shown. The compressed air may contain a lubricant.

Title: Improvements in or relating to magnetic escapement mechanism
IPC: G04C5/00
Filed: 1949-05-28
Abstract: 698,406. Timepieces. HORSTMANN CLIFFORD MAGNETICS, Ltd., and CLIFFORD, C. F. May 17, 1950 [May 28, 1949]. No. 14326/49. Class 139. A magnetic escapement in which relatively rotatable and oscillatable parts are coupled together magnetically so that the speed of rotation of the rotor is controlled by the frequency of oscillation is characterized by a rotor having at least one projection on its periphery and a cooperating stop member mounted to be just clear of the projection at normal escapement speed of the rotor, said rotor and said stop member being mounted for secondary vibration relative to each other, the natural frequency of said secondary vibration being so chosen as to be in excess of the natural frequency of oscillation of the escapement mechanism and impulsed, during rotation of the rotor at normal speed, in damped or out of tune frequency, and whereby the stop member is adapted to be contacted by the rotor projection by reason of the relative increase of amplitude of the secondary vibration only when the rotor rotates, on disruption of the normal magnetic coupling, at a speed sufficient to impulse the secondary vibration at or close to its natural frequency. The invention is applied to the type of magnetic escapements described in Specifications 596,216 and 660,581. The oscillator, Fig. 1, comprises a U-shaped magnet 2 carried by a plate spring 3 and the rotor is the escape wheel 1 mounted on a shaft 9. One end of a stop member 8 lies adjacent the peripheral extensions 7 of the rotor. As the rotor 1 rotates a transverse vibration is imparted thereto and if the rotor " runs away" from the oscillator the amplitude of this vibration will increase until the stop member 8 abuts an extension 7 to arrest the rotor. The transverse vibration of the rotor is produced by any static or dynamic out of balance of the rotor and shaft assembly and/or the impulses resulting from the reaction of. the poles of the magnet 2 on the escape wheel 1. In another example, Fig. 2, the stop member is a permanent magnet 12 impulsed to vibrate in a lateral direction by interacting magnetically with the rotor 1. When the rotor " runs away " from the oscillator 2 the amplitude of the vibration of the magnet 12 increases until it abuts an extension 7 and arrests the rotor 1.

Title: Forging machine for longitudinally and transversely profiled workpieces
IPC: B21J7/14
Filed: 1956-05-15
Abstract: 811,158. Swaging machines. KRALOWETZ, B. May 15, 1956 [May 18, 1955], No. 15096/56. Class 83 (4). A swaging machine for swaging longitudinally and transversely profiled workpieces, particularly turbine blades, comprises radially acting hammers 2, Fig. 5, actuated by eccentrics 1 carried by eccentric adjustable bearings 4 for varying the hammer stroke, each hammer having a hammer tool 24 rotatably mounted on an axis 28 and whose angular position is varied incrementally in dependence upon the feeding in of the workpiece. The periphery of the tools 24 is shaped to impart the desired transverse and longitudinal profile to the workpiece as they are rotated between forging blows. Each tool reciprocates horizontally and is fixed to a tool carrier 23 whose rear surface has three circumferentially extending wedge-shaped ribs 25, Fig. 4 (not shown), fitting into corresponding recesses 27 in an enlarged head 26 of the hammer 2. Stub shafts 28 of the carriers are engaged by spring-loaded links 29, Fig. 4 (not shown), which bias the carriers towards the hammers 2. The latter reciprocate through guides 22, Fig. 5, which are oscillatably mounted on horizontal axes whereby the tools 24 perform a slight vertical movement during their horizontal reciprocation. The tools do not rotate about their axes 28 during this oscillation. For varying the stroke the bearings 4 carry spur gears 6, Fig. 3, which are rotated by a rack 10 actuated by a double-acting hydraulic piston 11, Fig. 2 (not shown); the spur gears 6 of the two hammers are interconnected by an intermediate gear 8 and rack 9, Fig. 2 (not shown). Adjustable stop collars on the rack 10 co-operate with means for controlling the feed pump of the stroke-varying hydraulic piston and hence automatically controlling the stroke. The workpiece 38, Fig. 6, is pulled vertically between the tools by a gripper 37 connected to a double-acting hydraulic piston 35. A rack 39 secured to move with the piston rod 36 meshes with a pinion 40 connected by a universally mounted shaft 41 to gear 42 which drives gears 43, 45 connected through universally mounted shafts 44, 46 to the stub shafts 28 of the tools 24 whereby the tools are rotated in dependence upon the feed. Adjustable stops 52 on a disc 51 rotatable with the gear 43 co-operate with a fixed stop 53 for limiting the feed movement and with a limit switch 54 which causes the tools to be moved apart after the forging operation. The entire feed mechanism is resiliently mounted and is connected by linkage 49, 50 to one of the hammers so as to cause the workpiece to move vertically with the tools during their oscillating movement.
