Title: Improvements in and relating to tractors
IPC: B62D55/125
Filed: 1949-02-11
Abstract: 658,672. Agricultural tractors. FORD MOTOR CO., LTD., and SALMON, N. Feb. 11, 1949, No. 3833. [Class 79 (i)] A tractor has a half-track assembly secured as a unit at each end of the rear axle, each unit comprising a frame carrying idler wheels, a driving sprocket and a ground wheel, the groundengaging portion of the track between the driving sprocket and the ground wheel being inclined upwardly towards the front of the vehicle. A speed-increasing gear is preferably interposed between the vehicle axle and the track driving sprocket whereby the tractor may travel at the same speed as when fitted with the normal large rear wheel. As shown, the track f embraces a driving sprocket d, ground wheel e and two idler wheels b, c which are eccentrically mounted to facilitate adjustment of track tension. The sprocket d is driven by chain i from a gear g, secured to the axle end. The chain and chain gears are enclosed in a two-part casing a<SP>1</SP>, a<SP>2</SP> which is bolted to the flanged end h of the axle casing. As shown, the ground-engaging portion of the track between the sprocket d and ground wheel e is inclined upwardly towards the front of the vehicle. This keeps the weight-supporting portion of the track behind the rear axle and improves adhesion of the steering wheels. The arrangement permits of the attachment of implements by means of the normal linkage, since the half-track assembly does not project rearwardly unduly.

Title: Improvements in filters
IPC: B01D33/00
Filed: 1928-02-07
Abstract: 298,835. Bramwell, B. Feb. 7, 1928. Filters with loose filtering- materials. - Sand or other filtering-medium is washed in an open-ended tube, situated within the filter chamber, and up which the medium is carried by a stream of clean water directed upwardly into the tube from a nozzle. As shown in Fig. 1, the base of the filter A is spherical and the corners are rounded off by asphalt fillets E, so that during cleaning the sand passes readily towards the injector F, which lifts it up a washtube G for re-distribution over the top of the bed by a deflector J. During filtering the water under treatment enters by a pipe L, filters downward through the bed, and passes away through a perforated partition B and a pipe D. The corner above the annular filtrate chamber is filled in with a fillet E<1>, the surface of which is continued downward by a conical shield H. The flow through the pipes L, D and the pipe F', through which clean water is supplied to the injector, is controlled by a single rotary valve M. During cleaning, dirty water separating from the sand above the bed is discharged through a pipe K. It is preferred to arrange for a supply of clean water to the filtrate chamber to give a reverse upward flow through the medium during cleansing. A filter may be provided with several injectors and wash pipes, the bottom of the filter being suitably contrived to direct the sand to the several nozzles. Motion of the medium towards the injector or injectors may be aided by suitably directed auxiliary jets. In the filter shown in Fig. 5, the sand is supported on a false bottom formed of two perforated plates with an interposed sheet of gauze. The floor of such a filter may be shaped to form a cone around each of the injectors. The rotary valve M, Fig. 1, may be automatically actuated to control the periods of filtration and cleansing by a device shown in Fig. 8. The valve is actuated by a rod Z connected by suitable linkage with a piston O<1>. When the pressure in the filter chamber rises above a predetermined level, water passes through a pipe T and valve R to below the piston O<1> raising the piston, and with it a bucket Q, and, by means of tappets Q<1>, I<1>, a tappet-rod I operating valves R, S. The rod I, on raising, shuts off the space below the piston from the pipe T and opens it to a waste pipe U. It also opens the valve S to supply liquid to the bucket Q. With the fall of the bucket and piston the valves R, S are again reversed. Resistance to the movement of the piston O<1> is controlled by a regulating-cork W in a pipe connecting the upper end of the piston cylinder with an open tank above it.

Patent GB-588410-A (GB)
Title: New monoazo dyestuffs
IPC: C09B29/08
Filed: 1945-02-16
Abstract: Monoazo dyestuffs are manufactured by coupling a diazotized p-nitraniline or a halogen derivative thereof with a sulphuric ester of an N-hydroxyalkyldiphenylamine which is devoid of nuclear substituents and in which the alkyl radical contains 2 or 3 carbon atoms, or a salt thereof.  Alternatively, the free hydroxyalkyl compound is used as coupling component and the dyestuff is converted into its sulphuric ester by treatment with sulphuric acid or other known reagent for this purpose.  The products, in the form of their alkali metal or ammonium salts, dye cellulose acetate rayon in dischargeable orange, red or yellowish brown shades from a neutral, slightly acid or slightly alkaline bath, e.g. one containing Glauber's or common salt, and are suitable for dyeing from the winch with dilute dyebaths.  They may also be used for printing cellulose acetate rayon and for dyeing nylon, wool, natural silk, tin-weighted silk and leather.  Examples describe the production of the following dyestuffs: (1) to (3) p-nitraniline, 2 - chloro - 4 - nitraniline or 2 : 6 - dichloro - 4 - nitraniline --> the sodium salt of N-b -hydroxyethyldiphenylamine sulphuric ester; (4) p-nitraniline --> the sodium salt of N-b -hydroxy-n-propyldiphenylamine sulphuric ester. In further examples: (5) the dyestuff 2-chloro-4-nitraniline --> N - b  - hydroxyethyldiphenyl - amine is treated with 85 per cent sulphuric acid; (6) cellulose acetate rayon yarn is dyed reddish-orange with the product of (1) from a bath containing sodium chloride (added progressively during dyeing).  Additional diazo components specified are 2 : 5-dichloro-, 2 : 6-dibromo- and 2-chloro-6-bromo-4-nitraniline. Specifications 181,750 and 237,739, [both in Class 2 (iii)], are referred to.  N - b  - Hydroxyethyldiphenylamine sulphuric ester is obtainable by treating the free hydroxy compound with chlorosulphonic acid in ethylene dichloride.  N - b  - Hydroxy - n - propyldiphenylamine is obtainable by treating diphenylamine with propylene oxide at 170 DEG  C., and may be similarly converted into its sulphuric ester.

Filed: 1963-01-31
Abstract: 1,077,371. Supporting overhead conductors. R. RUTENBERG. Jan. 24, 1964 [Jan. 31, 1963; July 17, 1963], Nos. 4055/63 and 28344/63. Heading H2C. Overhead line conductors are supported by two insulators which extend in opposite directions transverse to the conductor length and include between them an angle of more than 90 degrees. Such an arrangement is said to lead to improved washing of the insulators by rain. In the arrangement shown in Fig. 2, the conductors 5 are supported by insulator strings 6 slightly inclined upwardly from the horizontal and anchored between the middle and one of the supporting posts 7. The spacing of conductors is increased by staggering them slightly by inserting an extension element 12 at opposite ends of successive mounting arrangements. The central post may not reach the ground but may be supported on a horizontal bar itself supported between the two outers (Fig. 3, not shown). The conductors may be supported from a vertical insulator string depending from the junction of the approximately horizontal strings (Fig. 4, not shown). A conventional tower may be used (Fig. 5, not shown), by providing additional supports at its sides between which and the pylon the double insulator strings are mounted. Two conductors may be mounted between the inclined insulators these conductors being spaced by a further string of insulators (Figs. 6, 7, and 8, not shown). Such arrangements may be mounted between vertical posts (Figs. 6 and 7, not shown) or between a pair of adjacent conventional pylons (Figs. 10-13, not shown). The Specification states that insulators in compression inclined downwardly from the conductor to the supports may be used. Apparatus for agitating the conductors or for directing fluid blasts on to them to remove snow are described.

Title: Improvements in or relating to tanks for electrical transformers
IPC: H01F27/12
Filed: 1921-02-03
Abstract: 182,506. Imray, O., (Pittsburgh Transformer Co.). Feb. 3, 1921. Tranformers.-A transformer tank comprises a body portion of corrugated sheet metal having the ends of the corrugations rounded over and the meeting edges thereof welded together to form a rounded arch, the bodies of the corrugations between these welds being bent to form a continuous inclined surface which meets the welds in a continuous ridge. The body portion is made from a series of sections 33, Fig. 3, which are notched at 34, leaving straight portions 35 between the notches. Each section is bent into corrugated form as shown in Fig. 5, the outer bends of the corrugations being centred at the peaks 41 of the notches. Each section is then bent into an arc corresponding to the shape of the tank, and the sections are assembled in cradles and welded together along their meeting edges to form the body portion of the tank. The ends of the outer corrugations are then rounded over and welded along the meeting edges 52, Fig, 8, while the ends of the inner corrugations are fattened over as shown at 49, to form the inclined surface meeting the welds in a continuous ridge. The bottom M of the tank, Fig. 2, comprises a dished plate, the edge of which is welded to the inclined surface adjacent tc the ridge. An angle-iron ring 60 is welded to the ridge at the top of the tank to support the cover C, and reinforcing-bands 75 may be welded to the tank outside the corrugations. The transformer is mounted in a frame F which carries bolts 20 extending through the cover C, the ends of the belts being enclosed by air-tight caps 21. The tank is supported in a base B, Figs. 2 and 11, formed of beams 76 and crossbars 79 fastened together to from a grid-like structure, on which are mounted curved anglebars 81, the flanges 82 of which engage the sides of the tank.

Title: Methods and apparatus for measuring the rate of flow of flowable material
Inventor: ANDERSON JAMES BERGEN
IPC: G05D11/13
Filed: 1966-01-31
Abstract: 1,141,004. Automatic flow control. H.J. HEINZ CO. Jan.31, 1966, No.4235/66. Heading G3R. Material flows from a source through a measuring vessel to a receiver and the rate of flow to or from the measuring vessel is determined by stopping the flow from or to the measuring vessel for fixed periods at regular time intervals and detecting the rate of variation of the quantity of material in the measuring vessel. In Fig. 2, a liquid or flowable solid material is discharged intermittently from a hopper 11 through a conduit 12 into a vessel 13 from which it is drawn continuously by a motor-driven pump 21. Vessel 13 is carried by a weighing machine 65 and overfilling is prevented by a float 17 controlling a valve 15a in conduit 12. A timer relay periodically closes a valve 15 and during each closed period the level in vessel 13 falls. The weighing machine pointer 72 carries a flag 72 which interrupts the light received by photo-cells 67, 68, 69. If, by the time that the timer relay opens valve 15 again, flag 71 is between photo-cells 68, 69, the rate of withdrawal is correct. If, however, flag 71 has not reached photo-cell 68 or has passed photocell 69, a relay circuit with which the photo-cells is associated operates a reversible electromagnetic ratchet motor to adjust the speed of pump 21 in the sense necessary to correct the rate of withdrawal. To avoid errors caused by the effect of changing head in vessel 13, the latter may consist of an upper section, in which the level varies during measurement discharging into a lower section which is maintained full and from which the pump extracts. The rate of flow may alternatively be measured by detecting the change in weight of vessel 13 by means of load cells or a weighbeam varying pneumatic pressure applied through electrically operated valves to bellows associated with a lever system incorporating integral feedback. Rate of flow is indicated and integrated to indicate total flow by an instrument responsive to the pneumatic pressure. Arrangements are also described in which a float valve in the vessel maintains a minimum level, a valve in the outlet is closed periodically, and the rate of increase of material in the vessel then controls pump speed to maintain the rate of supply of material to the vessel constant.
