Title: Improvements in or relating to steroids and the manufacture thereof
IPC: C07J5/00
Filed: 1960-12-19
Abstract: The invention comprises compounds having the general formula: <FORM:0946579/C2/1> wherein A represents hydroxyl, - OPO3H2, OSO2R11 wherein R11 is an alkly or aryl radical, or OAcyl the term Acyl representing the acyl radical of an organic carboxylic acid, R1 represents a b -hydroxy or keto group, X represents <FORM:0946579/C2/2> or <FORM:0946579/C2/3> , R being attached at the 2-position and representing hydrogen or methyl and Z represents hydrogen, methyl or fluorine provided that when X represents -CH=CH- or -CH2-CH2-, Z represents methyl or fluorine, pharmacologically acceptable water-suloble salts thereof pharmaceutical compositions thereof and a process for the preparation thereof by subjecting a compound having the formula: <FORM:0946579/C2/4> to oxidative hydroxylation and then, if desired, hydrolysing and/or oxidising to produce the corresponding free 21-hydroxy compound and 11-keto derivative subsequently the 21-hydroxy compound may be treated with an alkyl or aryl sulphonyl halide to obtain a 21-OSO2R11 compound which may be treated with an alkali metal iodide to obtain a 21-iodo compound or silver dihydrogen phosphate to obtain a 21-OPO3 H2 compound; treating the 21-OSO2R11 or the 21-iodo compound with a metal fluoride produces the 21-fluoro compounds. Alternatively the 21-phosphate is obtained by treating the 21-sulphonate with phosphoric acid in the presence of a tertiary amine and then acidifying the 21-hydrogen phosphate so produced to obtain the free 21-phosphate compound.  The oxidative hydroxylation may be effected using osmium tetroxide and an oxidising agent e.g. hydrogen peroxide, an alkyl peroxide or an amine peroxide. The starting compound is obtained by reacting a compound having the formula: <FORM:0946579/C2/5> wherein Ac,X and Z are as defined above, with selenium dioxide to give a compound of the formula: <FORM:0946579/C2/6> and converting the latter compound to a compound having the formula: <FORM:0946579/C2/7> wherein Y is chlorine or bromine, by treatment with thionyl chloride or thionyl bromide, reacting the latter compound with a base in the presence of an inert solvent to produce a compound having the general formula: <FORM:0946579/C2/8> reacting the latter compound with anhydrous fluoride in the presence of an inert solvent to give a compound having the general formula: <FORM:0946579/C2/9> and then acylating to produce the corresponding 21-ester.  Said compositions having anti-inflammatory properties, are administered in conventional dosage forms such as pills, tablets, capsules, syrups. or elixirs for oral use, or in liquid forms as injectable products, or topically in the forms of ointments, creams or lotions, with or without coacting antibiotics or germicides.  Specifications 850,833, 872,112 and 873,219 also are referred to.

Title: Improvements in or relating to wheeled vehicles
IPC: B60B15/26
Filed: 1956-12-17
Abstract: 837,107. Adjustment of orientation of tractor driving wheels. VAN DER LELY, C. Dec. 17, 1956 [Dec. 17, 1955], No. 38448/56. Class 108(2) [Also in Group XXXIV] In a wheeled vehicle, means is provided for canting a running wheel 14 into at least two working positions, in at least one of which the wheel axis lies at an angle to the horizontal, the wheel having at its circumference at least two differently shaped surfaces or groups of surfaces, the arrangement being such that in at least one of the two positions of the wheel 14 only one of the surfaces or groups of surfaces is in contact with the ground. As applied to a tractor, each end of the rear axle 11 is cranked at 13 and is pivotally connected at its extremity 16 to a fork 17 carrying a stub axle 18 for the wheel 14. The inclination of the plane of the wheel may be varied by the action of a hydraulic piston and cylinder 24 connected between the outer end of the fork 17 and the axle 11. The cylinder 24 is connected to a hydraulic pump driven by the engine of the tractor. This pump is also connected to hydraulic motors (not shown) incorporated in the hubs of the wheels 22 for driving the wheels 22 and actuating the brakes. If it is desired to increase the track of the vehicle, bolts 51 of a clamp 50 for the axle 11 are released and the tractor is driven forwardly so as to bring a rotation of the axle 11, so that the crank extensions 13 are inclined upwardly instead of downwardly as shown in Fig. 1. The wheels are then canted outwardly from this position to obtain the greater track width (Fig. 8, not shown). Anti-skid members 27 are carried by a ring 29 which is adapted to be secured to the outer face of the wheel 14. In an alternative form (Figs. 5 and 6, not shown), the ring 30 carries a cage-like member of frusto-conical shape. Instead of the ring 30 and associated anti skid members, a tyre (see Group XXXIV), having two respective zones of differing type of tread surface, may be employed for the wheels 2. The axle 11 may be axially slidable relative to the clamp 50. The pivot 16 for the fork 17 may be located away from, instead of coincident with (as shown in Fig. 1), the plane of the wheel 22.

Title: Improved mechanism for the guiding of weft threads in shuttleless looms
IPC: D03D47/00
Filed: 1964-09-25
Abstract: In a shuttleless loom wherein more than one weft (15) may be selected for simultaneous picking the loom is stopped if any one selected weft breaks.  Upon selection guides (3) are moved downwardly so that contacts (7) ride in L shaped slots (8) and the tension of the wefts turn the guides against the action of springs (16).

Abstract: 1,111,094. Relaxation oscillators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 25 July, 1966 [16 Sept., 1965], No. 39873/65. Headings H3P and H3T. A relaxation oscillator switchable to two different frequencies defined by the oscillator components includes a resonant circuit tuned approximately to an integral multiple of each of the defined frequencies for stabilizing the relaxation frequency. Fig. 2 (a) shows a synchronized multivibrator for generating the line scan of a 405/625 television receiver. The circuit C1 L1 is tuned to 30 kc/s. so that a 405-line scan includes about 3 cycles of this frequency and a 625-line scan includes about 2 cycles. It is explained (Figs. 2b and 2c, not shown) that the presence of this tuned circuit reduces timing errors due to false triggering by interference. The LC circuit may be tuned to a multiple of 30 kc/s. and may be included in the anode lead of B2 or in series with C3 (on either side). A series resonant circuit may be used, and the valves may be replaced by transistors. The invention is applicable to relaxation oscillators of other than the crosscoupled multivibrator type.

Title: Hydraulic control system for use in automatic transmissio
IPC: B60W10/10
Filed: 1977-09-23
Abstract: 1536819 Change-speed gear TOYOTA JIDOSHA KOGYO KK 23 Sept 1977 [28 April 1977] 39840/77 Heading F2D In an automatic transmission having an hydraulic control system a shift valve 57, operated by opposing throttle-variable and governor pressures, has a snap action during upshift due to a change of the area on which the governor pressure Pgo acts and due to the line pressure Pl assisting the movement once it starts to be supplied to the associated gearselecting friction device. Governor pressure Pgo from a vehicle speed responsive valve 53 initially acts on a land 94 through a port 96, which port is closed off as the valve spool 68 moves upwards to increase the area to that of a land 93. Line pressure Pl is supplied from a port 82 to an outlet port 84 when the spool 68 has moved sufficiently and the snap action is assisted by the pressure Pl then being supplied to a port 101 to act on a land 97. In downshifting, when the throttle-variable pressure, supplied to a port 70 from a valve 45, overcomes the governor pressure (on land 93) and the line pressure (on land 97) initial movement cuts off the pressure on land 97 to effect a snap action. The pressure on land 97 provides hysteresis. The valve 57 is the 2-3 shift valve. A 3-4 shift valve 58 operates in similar fashion but an opposing force from the line pressure Pl on the difference between lands 103 and 104 is cut off when the valve moves to upshift the transmission. Shift valve 56 is the 1-2 shift valve. Pressure from a valve 46 is used for kickdown when valve 45 is moved sufficiently. The transmission arrangement, shown in Fig. 1, comprises an overdrive section 2, providing fourth gear and a section 3 providing three forward speeds and reverse. There are one-way clutches 13, 28, friction clutches 12, 24, 25 and brakes 19, 26 and 27.
