Title: Power driven two wheeled tractors
Inventor: BURTON LESLIE JAMES
IPC: B60B11/02
Filed: 1954-06-18
Abstract: 771,693. Steering vehicles by declutching. CLIFFORD AERO & AUTO, Ltd. June 16, 1955 [June 18, 1954], No. 17908/54. Class 79(2). In a two-wheeled tractor comprising a powerdriven shaft 4 rotatably mounting at opposite ends wheel hubs 8 having dogs at their inner ends, an internally splined clutch member 9 for each hub is slidable on a splined portion of the shaft and is axially moved by a separate torsionally resilient actuating rod (not shown) having an actuating arm (not shown), the torsional resilience absorbing lost motion when the arm and the clutch member are in engaging and disengaging positions. As shown the shaft 4 rotatably carries driven gears 6, 7 of a twospeed gear, the gears 6, 7 being selectively connectable to the shaft 4 by a clutch member 5. The clutch members 9 are provided for steering purposes, and the torsional resiliency permits the clutch to be disengaged on reduction of frictional resistance in the clutch and after the arm has been actuated.

Abstract: 544,623. Cooling air and gas compressors. HOLMAN BROS., Ltd., and MILLS, E. C. Dec. 23, 1940, No. 18035. [Class 8 (i)] A compressor 1 is driven by an internal combustion engine 2, 3, and has an associated cooler such as an intercooler 4, through which the compressor air &c. passes : the cooler and the engine and compressor cylinders are cooled by an air current produced by a fan 10 and led through ducting 12, 13, 14 which correctly proportions the cooling air flow. The fan may be secured to the fly-wheel. The ducting embraces the intercooler 4 and engine cylinders 2, 3 ; one of its walls 18 extends beyond these cylinders and is louvred at the point 18a to distribute air to the cylinder 1 and an aftercooler. The compressor may be a two-stage single-cylinder compressor, the air from the first stage passing through an upper conduit 5 to the intercooler 4 and through a lower conduit to the second stage and to the aftercooler and outlet 9. The fan also delivers air to cool a vaned oil cooling sump 23, and through a duct 25 delivers air to supercharge the engine cylinders. The compressor cylinder may be vaned ; alternatively the engine and compressor cylinders may be water-jacketed, the air flow cooling the water. Specification 544,622 is referred to.

Filed: 1919-07-18
Abstract: 139,099. Wade, H., (Schneible, J.). July 18, 1919. Materials and compositions for making beverages.-In dealcoholizing beer &c. by distillation under reduced pressure, the vapours are treated to separate pure alcohol, the higher boiling portions are returned to the beverage and the lower boiling portions are either oxidized to form acids, which are added to the beverage, or are removed. The dealcoholized beverage is carbonated and cooled. Beer &c. is drawn into a heater A in which it is heated to 140‹ F. and then into a fractionator B where it boile under the reduced pressure. The mixture of liquid and vapour is passed by pipe B' into a column still C, heated at its base C' and surmounted by a dephlegmating column D, and by dephlegmators E, F which are supplied with cooling liquid. The higher boiling liquids which impart taste, flavour and aroma to the beverage are separated from the alcohol vapours in the dephlegmators and pass into the base of the still. Oxygen may be passed into the base of the column D, and copper screening may be arranged between the plates to act as catalyst for the oxidation of the lower boiling portions to form acids which pass into the residue. Alcohol vapours are drawn through a pressure-regulating valve in the head F and are condensed in a dephlegmator G, rectifier G<1> and dephlegmator H. The uncondensed vapours are withdrawn and reduced pressure maintained in the whole apparatus by a pump K. The dealcoholized residue is withdrawn from the base of the still C by a pump L, carbon dioxide is added from a pipe M, and the mixture is passed through a cooler N. Water of condensation from the coil in the base of the still may be used to dilute the residue. The fractionator B, still C, dephlegmator F, and the cooler N are fitted with thermostats.

Title: Improvements in or relating to band frequency selective wave guide filters for use on very high frequencies
Inventor: RAMSAY JOHN FORREST
IPC: H01P1/219
Filed: 1955-06-24
Abstract: 799,163. Band-selective waveguide filters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 9, 1956 [June 24, 1955], No. 18317/55. Class 40 (8). A band-selective waveguide filter comprises a length of waveguide containing two or more spaced resonant elements whose axes are arranged approximately transverse to the waveguide and out of parallelism with each other, the distance between the elements being less than one quarter-wavelength at mid-band frequency. In the simplest embodiment there are two elements consisting of spaced diaphragms having dumb-bell-shaped slots whose axes are arranged respectively at 60 degrees and 120 degrees to the broad face of the guide. Since the elements are at an angle to each other the filter depends for its operation upon evanescent modes and the elements are spaced by a distance (determined by experiment) much smaller than the usual quarter-wavelength to obtain critical coupling. The filter may be used as a coupling between a pair of colinear waveguides 6, 7, Fig. 3, which are twisted at an angle of 90 degrees with respect to each other. Arranged between the guides 6, 7 is a square section coupling cavity 11 terminated at either end by resonant elements 10, 12 in the form of dumb-bell-shaped slots. Each slot may be arranged at an angle of 60 degrees to the broad faces of the adjacent guide. The filter may also be used as a coupling between two guides 13, 14, Fig. 4, whose axes are at right-angles to one another and which are, in addition, twisted at 90 degrees with respect to each other. Portions of the end walls of the guides form the boundaries of a coupling cavity 15 and are provided with dumb-bell slots 20, 22. Each slot may be arranged at angle of 60 degrees to the broad faces of the adjacent guide. In the constructions of Figs. 3 and 4 coupling may be adjusted by varying the dimensions of the coupling cavity or the angle between the slots. The slotted diaphragms need not be exactly parallel or perpendicular to each other. The invention may be applied to provide coupling across a rotating joint. Band-stop filters may be constructed by replacing the slots by dipoles mounted on transverse partitions made of insulating material in mesh form. Ridge waveguides and circular waveguides may be used. By providing a large number of mutually inclined resonant elements the guide will act as a highly dispersive loaded line.

Abstract: 1,219,613. Cracking hydrocarbons. W. R. GRACE & CO. 18 April, 1968 [19 April, 1967], No. 18453/68. Heading C5E. Hydrocarbons, in admixture with steam, are cracked by contact with a catalyst containing a major proportion of crystalline aluminosilicate molecular sieve having the formula: wherein M is a cation of valence n, x is from 0 to 1 and y is from 0 to 9, at 350-1000‹ F. Suitable aluminosilicates have the alkali metal exchanged by a rare earth metal, e.g. didymium. The catalysts may contain up to 10% of silicaalumina, silica-alumina-magnesia, silica-magnesia, and clays and from 10<SP>-4</SP> to 10<SP>-1</SP> wt. per cent of promoters such as the precious metals Pt, Pd and Rh and their salts, e.g. rhodium sulphide, salts of Co and Mo and of the metals of Group VIB, e.g. tungsten sulphide. The catalyst may be pelleted, extruded or used as a slurry, e.g. in oil, in downflow, upflow, crossflow or fluidized beds and prior to use can be saturated with steam. Suitable hydrocarbon feeds have boiling points of 300‹ F. up to kerosene fractions, middle oil distillates, high boiling gas oil, residual stock, hydrogenated gas oil, coker oils and visbreaker gas oils. A hydrogen donor; e.g. hydrogen, partially hydrogenated aromatic middle distillate, naphthenic hydrocarbons such as tetralin, cyclohexane and decalin, and anthracenes can be included in the feed. The partial pressure of steam in the feed is suitably 0.02 to 0.40 atms. per atmosphere of total pressure when that of hydrocarbon is 0.25 atms.; the total pressure is from 0À01 atms. to 50 p.s.i.g. The examples relate to the conversion of n-hexadecane using helium as an inert diluent.
