As shown the underside of each ramp member 7 is formed with two spaced apart projections 9. Ramp members 7 are of hardened or case hardened steel whereas the surface 10 of the thrust plate 1 with which the projections 9 engage is of a softer material. After initial assembly of the thrust device and during the initial actuations thereof, any unequal axial loads exerted by the individual rollers 5 resulting from manufacturing tolerances in the ramp members 7 and thrust plates 1, will be smoothed out as the excess load on some of the ramp members 7 causes their projections 9 to dig into the surface 10 to permanently deform the surface 10 to provide an even load distribution throughout the rollers 5 of the thrust device.

The member 2 may be supported on a pivot pin 8 of a member 1 which is reciprocated against the bias of a tension spring 80 by a solenoid 5, a spring 9 urging the member 2 into engagement between successive packs during advance, but allowing the member 2 to be retracted by pivoting on the pin 8 for return movement. The member 1 is reciprocated until a required number of packs, possibly from a series of strips b have been advanced, whereupon a present counter 28 deactivates the solenoid 5. A solenoid 22 is then actuated, pivoting a crank 21 to raise a movable blade 17 of the cutting means 14, co-operation with a fixed blade 16 effecting cut-off of the strip b. Alternatively, Fig.7, a discharge pawl 34 for advancing the strip b may be reciprocated by an oscillatory crank 33, whose oscillation is effected by connecting rods 36, 37 driven by a disc 35. When the required number of packs have been dispensed, a counter 68 de-activates a solenoid 58, causing a crank 50 to be pivoted about a pin 52 by a spring 65, so that a roller 51 pivots the pawl about a mounting pin 40 to withdraw it from a slot 12 in the base-plate 11. Actuation of a solenoid 56 causes a roller 45 to be pivoted about a pin 43, pushing a pin 42 pivoted to the crank 33 upwards, so that it contacts a portion 60 of a crank 55, thus causing the movable blade 17 to execute a cutting stroke during the following oscillatory cycle of the crank 33. Further, Fig.9, the discharging member may take the form of a bar 67 which is moved along the whole length of the base-plate 11 by a rack and pinion drive 69, 77, optical scanning means 73 being provided to stop dispensing when the predetermined number of packs have been discharged.

Abstract: 1372370 Chucks; grinding TOYO BEARING MFG CO Ltd 10 Nov 1971 [5 Dec 1970] 52245/71 Headings B3B and B3D A method of controlling chucking pressure on rotating workpieces in machining, e.g. by grinding the inner and/or outer periphery of an annular ring held by a chuck having means abutting, only the axially opposite ends of the workpiece, in which the pressure of the chuck upon said opposite ends is applied by fluid pressure, and in which the machining comprises initially shaping the workpiece rapidly at a high pressure of a tool upon the workpiece followed by finishing the workpiece at a lower pressure of a tool upon the workpiece, is characterized in that ford the initial shaping the chuck is supplied with fluid at a pressure to hold the workpiece under the said high tool pressure and at completion of the initial shaping the fluid pressure is reduced over a predetermined period of time to a level sufficient to hold the workpiece under said lower tool pressure during the finishing process to thereby avoid distortion of the finished workpiece. In the embodiments described a chuck is operated by a fluid pressure cylinder 2 and for rough cutting pressure fluid passes through a valve 1 and a throttle valve 4 which sets a high chucking pressure. For finish machining the valve 1 is closed and fluid passes through a throttle valve 3 which sets a low chucking pressure. To prevent a sudden drop in chucking pressure an accumulator 8 may be placed in the circuit, and a further throttling valve may be provided (Fig. 6, not shown) to allow the chucking pressure to initially drop below the finish machining level to release stresses, and then to be increased to the finish machining level.

Title: Process for the preparation of dimers of bicyclo-[2,2,1]-hepta-2,5-diene and its alkyl derivatives
IPC: C07C2/42
Filed: 1966-11-28
Abstract: The dimerization of bicyclo[2,2,1]hepta-2,5-diene or an alkyl derivative thereof boiling below 140 DEG  C. is effected at atmospheric pressure and at a temperature above 140 DEG  C. in the presence of a catalyst consisting of a complex compound of iron in a low oxidation state as central atom and having at least in part electron donating compounds as ligands.  Suitable ligands are bicyclo[2,2,1]hepta-2,5-diene itself, its dimers, and Lewis bases, e.g. a triarylphosphine.  The catalyst is preferably produced in situ by mixing a solution of a catalytically inactive iron compound such as iron (III) acetyl acetonate with a solution of a reducing agent such as aluminium triethyl, the solvent in each case being the monomer itself.  The mixing of the two solutions may be conducted in the presence of a small amount of dimer.  The process is preferably carried out continuously in the absence of solvents and under a blanket of inert gas, e.g. nitrogen.  If a solvent is desired benzene, xylene and THF are suitable.  The dimer mixture formed contains structural isomers of the following structures. <PICT:1108379/C4-C5/1> <PICT:1108379/C4-C5/2> The dimers may be hydrogenated at room temperature, at atmospheric pressure, in the absence of solvents, and in the presence of Raney nickel catalyst. The dimers are suitable as fuels for jet aircraft, and may be mixed with conventional fuels, e.g. gasoline, kerosene and JP4 fuel.
