Abstract: 1,146,695. Temporary wheels. TEXAS INDUSTRIES Inc. 18 March, 1966 [29 March, 1965], No. 12166/66. Headings B7D and B7H. [Also in Divisions A1 and B8] A self-loading agricultural vehicle comprises a frame 1 supported by ground wheels 3, 4, mechanism 12 for picking up crop or other material from the ground and mechanism 14 for transferring it to a load carrying space of the vehicle, and a drawbar that is pivotable about at least one vertical axis relative to the frame 1 by adjusting means 27 provided between the drawbar and the frame 1 of the vehicle. The mounting of an auxiliary wheel 41 is connected to the drawbar so that pivotal movement of the drawbar causes the height of the wheel axis to be changed relative to the frame. The wheel 41 is lowered to the ground when the drawbar is in the position shown in full lines in Fig. 1 and raised when the drawbar is in the position shown in broken lines. The drawbar comprises two perpendicular members 21, 22 and two parallel links 16, 18, which are pivoted to the frame at 15 and 17 and to the member 21 at 19 and 20, and is pivoted by a double-acting hydraulic ram 27 which acts on an extension 24 of the link 16 and is supplied through a control valve 47, with hydraulic fluid by a pump 45 driven through a shaft 49 from a p.t.o. shaft on a towing vehicle 23. The castoring wheel 41 is mounted on a parallelogram linkage 30, 31, 33, 37 of which the link 31 is fixed to the frame 1. The link 33 has an extension 42 which is connected by a coupling-rod 44 with the drawbar link 18 to raise and lower the wheel. In Fig. 3 (not shown) the coupling rod 44 is connected to the extension 42 through a helical spring (50) to provide a resilient wheel suspension and the drawbar is pivoted by a threaded rod (51) which is mounted between the drawbar member (21) and a nut (52) on the link (16) and is rotatable through a gear casing (54) from the tractor p.t.o. shaft. As shown in Fig. 1, the axle 2 on which the wheels 3, 4 are mounted may be pivotable about a vertical pin 6 by a rod 10 connected to the extension 24 of the link 16 between a position perpendicular to the axis of the drawbar member when this is on a longitudinal axis of the vehicle and a position at an angle to this axis when the drawbar is pivoted to one side of the vehicle. The vehicle has a movable floor and a crop lifter 14 which is preferably lifted when the wheel 41 is lifted on pivoting of the drawbar. The vehicle preferably has a gear casing from which the pump 45 and the crop lifter and movable floor are alternatively driven. In Fig. 3, the crop lifter is driven from the gear casing (54) through a belt drive (56), (60), (69) gearing and a chain drive (62), (65), (66). Reference has been directed by the Comptroller to Specifications 1,094,402, 1,109,821, 1,109,822 and 1,109,823.

Title: Injection moulding of plastic articles
IPC: B29C45/37
Filed: 1974-03-20
Abstract: 1448511 Injection moulding MONTEDISON SpA 20 March 1974 [20 March 1973] 12314/74 Heading B5A Articles having wrinkles on a selected surface or surfaces only are made by injecting plastics material into a mould, cooling the portion or portions of the article providing the selected surface or surfaces at a relatively low rate, and cooling the portion or portions of the article providing the remaining surface or surfaces at a relatively high rate. Thus portions of the mould in contact with the selected surface or surfaces may have a relatively low thermal conductivity, the remaining mould surfaces having a relatively high conductivity. Alternatively different portions of the mould may be maintained at different temperatures. In one example (Fig. 4) a driving mirror of polymethyl methacrylate is made in a metal mould 3 provided with an insulating polycarbonate inlay 4 which causes wrinkling only in a peripheral edge of the mirror leaving the frontal surfaces free of distortion. In Figs. 9, 10 (not shown), a disc of ABS was made in an injection mould having an insulating inlay (8) of polyamide resin around the circumference. In Fig. 13 an article having a strengthening rib is made in a metal mould 9 having insulating inlays 10 of PTFE. Insulating inlays of a polyester resin, a ceramic, polysulphone or polyphenylene oxide may also be used.

Title: Recovery of manganese from metallurgical slags, dusts and ores
IPC: C01G45/06
Filed: 1958-04-18
Abstract: <PICT:0880017/III/1> Materials containing manganese in oxidic and/or metallic form are contacted with chlorine at a temperature below 650 DEG C. (the melting point of manganese chloride) and sufficient to form manganese chloride, the manganese chloride is leached from the reaction product and recovered from the leach liquor.  Initial materials which may be used are natural and synthetic ores and slags, and particularly precipitator dusts collected in metallurgical operations.  The latter may contain up to 25% of manganese, together with iron, carbon, alkali metal (potassium, sodium, lithium) and various other metal oxides.  At the temperatures used, the alkali metal oxides are chloridized and leached with the manganese; iron oxide is also chloridized but separated by sublimation.  In the illustrated apparatus, the manganese material is first dried if necessary in a drier 2 and then changed into reactor 3.  The bed of material may be heated to the required temperature by external application of heat or internal resistance heating.  If iron is to be separated chlorine is first passed upwardly from supply 4 through the bed when a suitable temperature is reached and the resultant gaseous ferric chloride and any excess chlorine passed to condenser 12 where the former is condensed and removed, whilst the latter may be recirculated. Preferably the heating is regulated so that a temperature of 500-650 DEG C. is reached by the time the iron has been removed so that the manganese may then be chloridized with the greatest efficiency.  After removal of iron (or at the beginning of the operation if a separate step of iron removal is not used) a second condenser 16 is employed in a closed system in which the chlorine is circulated from said condenser, through a cleaning and drying tower (not shown) downwardly through the bed and returned to the condenser.  The condenser 12 may be cut out of the system or used in parallel with condenser 16.  During the chloridizing the solid material may be continuously passed through the reactor.  The chloridized material is then leached, preferably with water at the boiling point in an agitated vessel 21.  The liquor is separated from the gangue by means of filters, cyclones or centrifuges and then passed to a crystallizer evaporator where manganese chloride and any alkali metal chlorides are recovered for electrolysis to give manganese in cell 30, with or without the addition of further quantities of alkali metal chlorides. Chlorine resulting from the electrolysis may be recirculated to the chloridizing step.  Manganese metal may alternatively be obtained by smelting with a reducing agent.  Specification 821,922 is referred to.

Title: Improvements in devices for delivering paper to printing presses
IPC: B65H23/08
Filed: 1929-04-22
Abstract: 310,335. Kohler, G. A. E., (Assignee of Bernard, D. G.). April 23, 1928, [Convention date]. Feeding webs. - The web supply to a printing-press is controlled by a number of endless belts passing round guides arranged in fixed positions above and below the supply roll and being substantially within a vertical line tangent to the roll surface, means being provided for keeping the belts taut as the diameter of the roll decreases. A supply roll 9, Figs. 1 and 3, and reserve rolls 10, 11 are mounted in arms 3 on a shaft 1 which may be rotated by an electric motor 8 to bring the supply roll into contact with a number of narrow endless belts 12 passing round stationary guide rollers 13, 14, 16, 17, 18 and 28 and guide rollers 15 carried by levers 21 provided with weights 20 to hold the belts taut. The belts may be driven by the pull of the web or may be driven positively by connecting the shaft 14a of the rollers 14 with a driving shaft 41 through a clutch 42. When the press is stopped, the clutch is opened and a brake 57 is applied to the shaft 14a. For this purpose, a member 43 with conical ends 51, 53 is slidably mounted on the shaft 41 and connected to one end of a lever 44, the other end of which is connected to a spring 58 and to the armature 48 of a solenoid 47 in the circuit controlling the starting and stopping of the press. When the press is running, the solenoid is inactive and the spring 58 holds the member 43 in such a position that the conical end 51 acts upon the clutch levers 52 to hold the clutch closed. When the press stops the solenoid is excited and the member 43 moves to the right so that the clutch is opened and the conical end 53 actuates levers 54 to apply the brake 57. If the web passes downwardly from the roll to the press, the belt guides 18, 17 may serve as guide rollers for the web, in which case they are provided with grooves to receive the belts 12. The web may, however, pass round separate guide rollers driven by a chain from one of the belt guides or may pass upwardly from the roll to the press. When a roll is nearly exhausted, the shaft 1 is rotated to bring the next reserve roll, provided with adhesive, into contact with the expiring web, after which the old web may be severed. Instead of disconnecting the clutch 42 upon stoppage of the press, its member smay be kept in slipping contact to stop the rotation of the roll gradually. Also, instead of positively driving the belts, they may be driven frictionally by the roll.

Title: Improvements in tap changing systems in electric induction apparatus
IPC: H01F29/04
Filed: 1946-04-26
Abstract: 644,289. Transformers and inductors. BRITISH THOMSON-HOUSTON CO., Ltd. April 26, 1946, No. 12610. Convention date, April 27, 1945. [Class 38 (ii)] A tap-changing arrangement for a transformer or inductor having two multitapped windings on the same core, comprises a pair of contacts associated with each winding for making connection to the taps, each contact of one pair being connected to a contact of the other pair through one of a pair of arcing-duty switches, and one half of a split reactor. The intermediate taps of the windings 2, 4 are connected to the fixed contacts of the respective ratio adjuster switches 5, 6 which are engaged by pairs of contacts 9, 10 and 11, 12. The ends of windings 2, 4 are connected to the fixed contacts of two-way switches 7, 8, the fixed contacts of which are connected to contacts on switches 5, 6 and also to the end terminals 23, 24 ot the windings as a whole, through subsidiary windings 1, 3 if desired. By way of slip rings contacts 9, 11 and 10, 12 are connected to each other through halves 77, 18 and switches 13, 15 of split reactor 16 and the pair of arcing-duty switches 14 respectively. In the position shown the whole of the windings are in circuit and to cut out one section from winding 2, by means of mechanism such as that shown dotted, switch 13 is opened, contact 9 is moved clockwise to the next contact of switch 5, switch 13 is closed, when reactance 16 reduces the circulating current, switch 15 is opened, contact 10 follows contact 9 and switch 15 is closed. Similarly a section may be cut out of winding 4 by switch 6 and sections may be added to the windings by reversing the direction of operation of switches 5, 6. The effective tap range of each ratio adjuster switch 5, 6 may be doubled,'by operating two-way switches 7, 8 when the moving contacts 9, 10 and 11, 12 engage the lowest fixed contacts, so that windings 2, 4 are cut out of circuit, and further clockwise rotation of contacts 9, 10 and 11, 12 inserts tap sections step-by-step in the opposite sense. In the modification shown diagrammatically in Fig. 1, the fixed contacts of twoway switches 7, 8 are connected to the ends of additional windings 25, 26 and the moving contacts are connected to the ends of windings 2, 4. Tappings which can be engaged by the moving contacts 9, 10 and 11, 12 divide wind. ings 25, 26 into parts in which the induced voltage is V and NV, where N is the number of taps (including ends) of windings 2, 4 and V the voltage induced in each tap section. The ratio adjuster switches may be moved in one direction with the two-way switches 7, 8 as shown, to increase the turns in circuit, or in the other direction with switches 7, 8 in the other positions to reduce the turns. A modification for a three-phase circuit is described in which the two windings are on different limbs of the core, aviation of tappings on these zig-zag connected windings giving a phase shift as well as voltage change, Fig. 3 (not shown). If each two windings are on the same limb no phase change results.

Title: Steroid compounds and compositions thereof
IPC: C07J9/00
Filed: 1961-04-10
Abstract: The invention comprises compounds having the formulae <FORM:0924981/IV(a)/1> <FORM:0924981/IV(a)/2> and the corresponding D 1,4, D 1,4,6, and D 4,6 compounds wherein X is hydrogen, fluorine, chlorine and bromine, Y is halogen, alkoxy containing up to 10 carbon atoms, hydroxyl or acylated hydroxyl, the acyl group containing up to 10 carbon atoms and being derived from a mono- or di-carboxylic acid, and R is hydrogen, hydroxyl or acylated hydroxyl, and therapeutic compositions thereof.  The 21-halomethyl compounds of the above formulae are obtained by reacting the corresponding 21-methylene compound with anhydrous hydrogen halide in an inert solvent. Reacting the 21-methylene compound with an alkanol results in a 22-alkoxy compound.  This may be reduced to a 21-hydroxymethyl by hydrogenation provided the 3-keto group is protected, e.g. by forming a formate ester.  The 17- and 21-hydroxyl groups in the resulting compounds may be esterified by the usual methods.  The compositions have progestational activity and comprise the above compounds and a pharmaceutical carrier.
