Title: Improvements in the process of hydrogenating tar oils
IPC: C10G47/00
Filed: 1925-06-26
Abstract: Tar oils are hydrogenated at ordinary pressure and elevated temperature using coke oven gas from which the water vapour has been removed.  The coke oven gas is dehydrated by cooling, by calcium chloride or preferably by means of sulphuric acid, whilst the water formed during the reaction is vaporized at the temperature of the hydrogenation, viz. 180-200 DEG  C., and carried away by the gas. The tar oils are previously desulphurized in known manner with ferrous sulphate or bog iron ore.  An example is given of the hydrogenation of desulphurized tar oil in the presence of a colloidal nickel catalyst.  The product may be treated at a temperature of 180-200 DEG  C. with superheated steam to deprive it of its odour and colour.  Specification 18998/12 is referred to.ALSO:Tar oils are hydrogenated at ordinary pressure and elevated temperature using coke oven gas from which the water vapour has been removed.

Title: Improvements in locking means for telescopic jacks
IPC: F15B15/26
Filed: 1943-10-08
Abstract: 573,033. Hydraulic machines. DOWTY EQUIPMENT, Ltd., and BECK, G. Oct. 8, 1943, No. 16546. [Class 69 (ii)] [Also in Group XXX] In a lifting jack of the kind in which a locking device for the plunger is disengaged by fluid pressure, the lock comprises one or more balls, rollers or loose segments mounted in the barrel which are forced inwards to engage a shoulder on the plunger and locked in this position by endwise movement of a sleeve. The balls 8 are positioned in holes in a cage 9 secured to one end of the barrel 1. A sleeve 10 is slidably mounted between the cage and barrel and is provided with an annular recess 11 which, when brought into register with the balls, permits their movement outwards from the shoulder 5c on the plunger 5 to release the latter. The cage has an annular recess 13 and a piston face 14, and is loaded by a spring 15. When pressure fluid is admitted through the connection 12, the cage moves upwards and, as soon as the balls enter the recess 11, the plunger moves upwards if the space below the piston 6 is in communication with a source of pressure fluid through the connection 4. If this communication is closed, the fluid which has been admitted through the connection 12, and has passed through slots 16 in the sleeve 10 and slots 18 in the gland-locating ring 17. to the space above the piston 6, causes the retraction of the plunger.

Title: Improvements in and relating to power-assisted steering for motor vehicles
IPC: B62D5/24
Filed: 1957-05-27
Abstract: 819,559. Vehicle power steering. ZAHNRADFABRIK FRIEDRICHSHAFEN A. G. May 27, 1957 [May 26, 1956], No. 16823/57. Class 79(5) In a power-assisted steering unit for a motor vehicle a hydraulically actuated piston 3, Fig. 2, containing an axially slidable steering nut 6 movable by turning of the threaded steering spindle 7 tc actuate valve means controlling the supply of pressure medium tc one of the ends of the piston 3, the steering nut 6 has annular grooves 52, 53 at each end in communication with the pressure chambers 26, 27 at the respectively opposite ends of the piston 3 to provide "feel". The piston 3 is slideable in a cylinder casing 1 and slides with fluid tight engagement at one end over a sleeve 49 surrounding the steering column 10, with an intermediate annular pass 33 providing a fluid return line. The piston 3 actuates the steering shaft 13 through a connection rod 11 and splined crank lever 12. Passages 24, 25 in the piston 3 communicate with the chambers 26, 27 at each end of the cylinder 3 and with grooves 22, 23 on the nut 6 which constitutes in part a spool valve to which pressure is supplied through a port 15 (not shown) leading to an annular chamber 16 in the cylinder 1 and radial ports 18 in the piston 3. The low pressure return comprises end ports 58, 59 and central chamber 30 in the nut 6, the chamber 30 being connected to exhaust through a central passage 31 radial bores 32 and the annular passage 33. Endwise movement of the steering spindle 10 is prevented by bearings 8 engaging a flange 9 and axial movement of the nut 6 relative to the piston 3 is resisted by compression springs 41, 42 which tend to hold the nut 6 in a central position. The movement of nut 6 is limited as during manual steering by supporting rings 37, 38 which have pre-determined end play. Rotational movement of the nut 6 during turning of the steering spindle 10 is prevented by a bolt 60 inserted through the piston 3 and en-  gaging he nut 6. Steering "feel" is pro-  vided by the annular grooves 52, 53 at the ends of the nut 6 which are connected through passages 24, 25, and 50, 51 with respectively opposite chambers 26, 27 and are of different cross-sectional areas to compensate for the different cross-sectional areas of the ends of the piston 3. In a modification movement of the valve nut 6 is magnified by disposing the bolt 60, Fig. 5, at an angle in the valve nut 6 so that the nut is caused to rotate in the opposite direction to the spindle. Alternatively the bolt may have a roller 61, Fig. 6, engaging in a sloping slot in the piston 3.

In an inverter circuit of the kind forming the subject of Specification 697,367, in which condensers 6, 8 are respectively connected in parallel and in series with the load 5, in order to stabilize the output voltage despite fluctuations in the input direct voltage 1 and at low or zero loads, a variable inductor 9 or equivalent is connected across the output terminals. A further condenser 10 in parallel with inductor 9 may be provided. The inductor 9 may comprise two series-connected chokes with saturable cores carrying reversely-connected biasing windings fed from the supply 1, Fig. 2 (not shown), or from the inverter output through an auxiliary rectifier. The control may be manual or automatic, an adjustable resistor being varied by an automatic regulator responsive to the output voltage, or the auxiliary rectifier may have grids so controlled that the saturating current varies very rapidly when the inverter alternating voltage exceeds a set value. In a modification, Fig. 3 (not shown), the output transformer 3 and the variable inductor are replaced by an autotransformer with two saturable cores bearing two biasing windings so connected as to prevent induction in them of A.C. The voltage to the capacitors is stepped up to reduce their size and stepped down through another transformer feeding the load.
