Title: Improvements relating to Driving and Reversing Mechanism for Planing and like Machines.
IPC: B23Q5/22
Filed: 1917-06-09
Abstract: 115,523. Smith & Coventry, and Wright, I. H. June 9, 1917. Planing. - In magnetic-clutch driving and reversing mechanism for planing or like machines, with variable strength of current supply to the clutches, means are provided to ensure that the maximum clutch effort is exerted for a longer period at the commencement of the high speed return stroke, than at the end of the working stroke. The dog o, near the end of the working stroke, engages arm j of a lever pivoted at m, and causes a second arm i engaging with the fork q, to slide the bar h so that the switch brush a is moved from the medium-force contact e of the working-stroke clutch, first to the medium-force contact d of the return-stroke clutch, and then to the full-force contact c of the return-stroke clutch. This reverses the motion of the table, and as the dog o recedes, a spring s moves the lever i until the brush a rests on the contact d. The gap in the fork q being wider than the pin on the lever i, causes a longer dwell of the brush a on the contact c during the beginning of the return stroke than during the end of the working stroke. The dogs o and n may be stepped, to give a quick transference of the brush a from contact to contact.

Title: Partial hydrogenation of unsaturated glyceride oils in solvents
IPC: C11C3/12
Filed: 1948-03-25
Abstract: One part of an unsaturated glyceride oil having polyethylenic fatty radicles is mixed with 0.05 to 15 parts by weight of an inert volatile fat solvent and finely-divided hydrogenation catalyst, the mixture is agitated vigorously and hydrogen passed through, the temperature of the mixture being between 60 DEG  and 125 DEG  C., and the partial pressure of the hydrogen being at least 20 and not over 200 pounds per square inch gauge, until a major portion of the polyethylenic acid radicles have become more saturated, and then separating the hydrogenated oil from the solvent, catalyst and hydrogen.  Oils specified are cottonseed, soybean, sesame, and peanut oils, and they are partially hydrogenated so that their iodine values are between 50 and 90.  In examples: (1) cottonseed oil is mixed with ethyl alcohol and hydrogenated in the presence of nickel, the temperature of the charge being maintained at 90 DEG  C.  On reaction reaching the desired end point the solvent is distilled off; (2) soybean oil is mixed with 2-methoxyethanol, whereby two liquid phases of different amount of oil in the solvent are produced, the more unsaturated phase hydrogenating more rapidly, which is followed by a transfer from the more concentrated phase thereto; (4) 50-50 mixture of cottonseed and soybean oil is hydrogenated.  The process may be batchwise or continuous.  Solvents in order of preference are ethanol, methanol, isopropanol, cyclohexanol, acetone and ethyl ether. Mixtures of two or more solvents can be used, as also can a selective solvent, e.g. furfural and liquid propane near its critical temperature.  The catalyst employed is of nickel promoted by copper, chromium, cobalt, zirconium, thorium or their oxides. Specifications 658,188 and 658,189 are referred to.

Filed: 1923-03-29
Abstract: 222,173. Daponte, D. L. March 29, 1923. Printing - apparatus.- Stereoscopic effects in kinematograph projection are produced by alternately diminishing and increasing gradually the intensity of illumination or sharpness of definition of the image of one member of a plurality of i-tereoscopieally related views. In one example when taking the negative from which the positives used in projection are subsequently printed, a series of views are taken in succession in which the views presented to one eye are of gradually diminishing exposure while those presented to the other eye are of gradually increasing exposure, the variation being effected by a graduated screen or by stopping down one lens and increasing the aperture of the other. The speed of the emulsion of the film may also be varied for the same purpose. When printing positives from a uniform negative film, similar means for varying the illumination of the positive may be used. A single film having the right- and left-hand views superimposed is made in a printing device fitted with two lenses 29, 29<a>, reflecting prisms 30, 30<a>, and a lens 31 to produce an image on the film 32, before which rotates a shutter 33 having graduated sections arranged alternately in addition to a shutter for presenting the right- and left-hand views alternately.

Abstract: 929,689. Nuclear reactors. FOSTER WHEELER Ltd. March 13, 1962 [March 13, 1961], No. 9074/61. Class 39 (4). A nuclear reactor vessel containing a reactor assembly core is shielded from radiation from the core by removable shielding made up of segments which can be inserted and withdrawn through an opening in the vessel through which the core can pass but the assembled shielding cannot, the segments being interlocked within the vessel. In Fig. 3 the reactor vessel A is protected from radiation from the core (not shown) by two coaxial metal rings C and D. The rings C and D are each made up of a number of interfitting segments, each segment of ring C being fixed to a corresponding segment of ring D by radial webs F and G to which both segments are welded. The assembly of segments is held in position at the bottom by the engagement of the curved lower ends of the outer segments D in notched plates M, and at the top by a sleeve P which is suspended in the neck E of the vessel and the lower end of which is notched to fit over the webs F. In a modification, Fig. 2 (not shown), the segments are provided with chevron joints except for one pair of segments which is provided with non-interlocking joints similar to those shown in Fig. 3. To dismantle the shield the sleeve P is withdrawn and the pairs of segments removed one by one; in the construction of Fig. 2 the non-interlocking pair is removed first. As can be seen the joints between segments are non-radial so that there are no rectilinear radiation leakage paths.
