Title: Improvements in and relating to vehicle steering devices and the like
IPC: B62D7/15
Filed: 1925-11-19
Abstract: 266,058. Preston, J. E. Nov. 19, 1925. Steering; deflectable axle-ends and intermediate connections therefor.-In a motor road vehicle having a power unit driving at least two road wheels means are provided for displacing all the road wheels into such a position that they are adapted to rotate in a common circular track whereby the vehicle may be revolved about a vertical axis, An auxiliary drive is imparted to some or all of the road wheels to rotate the vehicle, and this drive may also be used to roll the wheels into the auxiliary position. In the construction shown the front wheels A, B are normally steered in the usual manner, their stubaxles being connected together bv a telescopic track rod 10. The rear wheels C, D are mounted on stub axles 3, Fig. 4, capable of swivelling about an axis a, a, but are normally not steered and are normally driven through differential gearing, axle-shafts 9, and universal joints 3<b>. The front and rear wheels are each provided with auxiliary driving means comprising a shaft 8, a universal joint in line with the steering pivots a, a, a clutch 7, and spur gearing 4f, 4<b>. The shafts 8 can be driven from the engine or propeller shaft through gearing 11<b>, a clutch 14, and intermeshing bevel wheels 12<a>. The auxiliarydrive. clutches 7 are controlled by a pedal 15 through cams 16 and Bowden wire or other connections 18, or electrical control may be employed. To set the road wheels so that their axles radiate from a common centre, a detent 10<b> on the track rod 10 is disengaged leaving the rod free to telescope, and the rear wheel stub axles are also made free tc revolve about the pivots a, a. The pedal 15 is then operated to bring the cams into a position such that all four clutches 7 are engaged. When the clutch 14 is engaged the auxiliary drive thus imparted to the wheels rolls them and their stub axles into the positions shown in broken in Fig, 2; the detent 10<b> then locks the track-rod in its shortened form, and means are provided for limiting the movement of the rear wheel axles. To rotate the vehicle the pedal 15 is moved to another position in which only two clutches 7 are engaged, either the clutches on the wheels A, D or those on B, ('. The auxiliary drive on these wheels now rotates the vehicle as a whole. The auxiliary drive from either of the wheels C, D may be transmitted to the other through the differential gear, the propeller shaft being held stationary, or a reversing gear may he provided in the auxiliary drives to allow all four wheels to be driven to rotate the vehicle as a whole. The road wheels may be swivelled into the auxiliary position by hand or foot power, the stub-axle arms for one pair of wheels being connected by links to the opposite ends of a centrally pivoted lever which is rotated by bevel or other gearing. Similar mechanism may be provided for the other pair of wheels.
Patent GB-748332-A (GB)
Title: Improvements in the preparation of granular industrial nitro-cellulose compositions
IPC: C09D101/18
Filed: 1950-11-29
Abstract: Granular or particulate solvent-free plasticized nitrocellulose compositions are produced by vigorously stirring a suspension of particulate nitrocellulose in water or in an aqueous solution of an electrolyte and/or a protective colloid with a mixture of an organic solvent for nitrocellulose which is insoluble or only sparingly soluble in water and readily volatile in steam, and a plasticizer for nitrocellulose which is insoluble or only sparingly soluble in water but soluble in the solvent.  After this step, while continuing the stirring of the complete mixture, the whole is heated to boil off the solvent.  The solvent may be a mixture of one or more volatile organic solvents for nitrocellulose, such as ethyl, butyl or amyl acetate, mixed with one or more volatile organic liquids which are nonsolvents for nitrocellulose and function as diluents, e.g. benzene or petroleum ether.  The solvent may be solely a solvent for nitrocellulose, e.g. ethyl acetate, while the water in which the particulate nitrocellulose is suspended may then contain a protective colloid such as starch, gum arabic, or a carboxymethyl-cellulose, and may also contain an electrolyte.  In an example there is added at room temperature and with vigorous stirring to a suspension of 100 kg. of crushed nitrocellulose in 600-700 litres of water a mixture of 40 kg. benzene, 60 kg. amyl acetate and 18 kg. butyl phthalate. The system is then heated slowly up to the boiling point of the solvent and maintained at this temperature so that the solvent is slowly distilled off.  The residue is allowed to cool, and the granules of plasticized nitrocellulose which have been formed are removed from the aqueous medium by centrifuging and dried at 55 DEG  C.  In another example a mixture of 135 kg. ethyl acetate, 15 kg. butyl acetate and 18 kg. butyl phthalate are added to vigorously stirred suspension of 100 kg. of nitrocellulose in 700 litres of water containing 2-3 kg. of a carboxymethyl cellulose and the solvent distilled off and the plasticized granular nitrocellulose separated and dried as before.

Abstract: 540,043. Chromites. UDY, M. J. Nov. 4, 1939, No. 29391. Convention date. Dec. 8, 1938 [Class 1 (iii)] A chromite ore containing ferrous chromite, alumina and silica is fused with added lime or magnesia in order to substitute these oxides for the ferrous oxide of the chromite, and the product is separated into two portions, one of which contains most of the chromium content of the original material while the other contains most of the alumina. The heating may be conducted to produce either a molten or a sintered material. The proportion of lime to silica may such that the product disintegrates on cooling. A carbonaceous reducing agent may be incorporated in the mix so that some or all of the ferrous oxide is reduced in the heating operation. The fused product may be decomposed with acid, or it may be subjected in finely divided form to a flotation or other separating treatment. The chromium-containing portion may be mixed with a non-carbonaceous reducing agent capable of reducing its chromium content.

Title: Web coating process
IPC: B29C48/92
Filed: 1969-06-10
Abstract: 1,269,979. Coating apparatus. FUJI PHOTO FILM CO. Ltd. 10 June, 1969 [10 June, 1968], No. 29452/69. Heading B2L. [Also in Division D1] Variations in the thickness of a coated layer applied to a moving web are negated by deriving an electric signal from disturbances which act to cause such variations, amplifying the signal and subsequently applying it as a potential difference between the coating compositions and the back of the web being coated whereby a varying and compensating electrostatic force of attraction occurs between the composition and the coating device. In Fig. 1 mechanical vibration of the apparatus is detected and converted to an electric signal at 7, which may be a capacitor-type vibration meter. The signal is polarity-reversed at 8, has its phase shifted at 9 and is amplified at 10, the output having a bias voltage applied thereto and being applied between the coating device 4 and the web 1 by electrodes 13, 14. As shown, the metal roller 3 carries an insulating layer 2. In another embodiment (Fig. 2, not shown) a multilayer coating is applied, and variations in the uncoated web thickness are measured and fed, via a time-delay device, as an amplified p.d. between the coating device and the web, as in Fig. 1. Different disturbance factors may be simultaneously detected and combined to produce an aggregate correcting p.d. Other types of detectors are specified.
