Title: Lubricating mechanism for the intermediate or translational bearings of contra-rotating airscrews
Inventor: CROWHURST JAMES ARTHUR
IPC: F16N7/38
Filed: 1949-01-07
Abstract: 662,147. Force feed lubricating. DE HAVILLAND AIRCRAFT CO., Ltd. Feb. 7, 1950 [Jan. 7, 1949], No. 525/49. Class 12 (iii). Lubricating mechanism for an intermediate or translational bearing of contra-rotating airscrews comprises oil pumps 8 adapted to be driven continuously by relative rotation of the two airscrews for circulating oil through the bearing 4 and an oil reservoir 7 in communication with the pumps 8 and bearing 4 for supplying oil to the pumps and for receiving oil drained from the bearing, the supply of oil to the bearing being proportional to the speed of rotation of the airscrews. The bearing races are carried by inner and outer parts 5, 6 of a housing, the parts being in driving connection with the adjacent airscrews. The reservoir 7 is contained within the part 6 which also carries the pumps 8, inlet valves 12 and outlet valves 15. The pumps 8 are of the intermeshing gear-wheel type and have shaft connections to multi-start worms 10 in driven connection with a worm wheel 11 carried by the inner part 5 so that the pumps are driven at a speed proportional to the speed of rotation of the airscrews. The inlet and outlet valves 12, 15 are centrifugally opened and spring closed, the arrangement being such that the outlet valves 15 open at a lower speed than the inlet valves 12. One or more breather valves 18 which are also centrifugally opened and spring closed are provided. A removable plug 19 is fitted for topping up the reservoir with lubricant. In operation lubricant passes from the reservoir by way of valves 12 into passageways 13 to the pumps 8 from which it is pumped through passageways 14 to the bearing. From the bearing, lubricant passes through passageways 16 and through valves 15 back to the reservoir 7. In a modification pumps driven by worm and spur gearing deliver lubricant to the bearing from which it is centrifugally returned, the inlet and outlet valves being dispensed with.

Title: Solvent extraction apparatus
IPC: B01D11/02
Filed: 1959-01-07
Abstract: Apparatus for the extraction of solids by liquids, e.g. soya bean flakes by hexane, comprises a vapour tight casing 11 within which <PICT:0847574/III/1> <PICT:0847574/III/2> <PICT:0847574/III/3> is a rotor 16 divided into a number of segmental cells 30 separated by inter-cell walls 29 and open at the top and bottom, the lower part of their outer peripheral walls 28 being liquid permeable (see Fig. 6 not shown).  The base of the casing 14 is in the form of a downwardly and outwardly sloping surface of revolution e.g. a canoid, terminating at the periphery in a compartmental annular trough 15 (see also Fig. 4 not shown) each compartment having a drainage hole 25.  The base also contains a shoot 20 for the discharge of extracted solids.  The base fits closely to the cell bottoms thus forming a fixed base therefore, cylindrical strips e.g. of "Teflon" (Registered Trade Mark) 37 with drainage holes 38 (see Fig. 6 not shown) may be used to give a close fit between the base and outer cell wall 28 the inter-cell walls 29 being similarly provided with rubber "wipers". Solids to be extracted enter the cells in a saturated or slurried condition via the charging inlet 19 (see Fig. 2 not shown) and having been extracted are discharged through the shoot after completing a predetermined angular path, preferably of not less than 270 degrees. Fresh solvent is fed as vapour through inlet 22 placed tangentially to the space between the casing and the rotor. Solvent containing extracts (miscella) drains into the compartments of trough 15 via the drainage gaps 35 in drain pans 34 on the periphery of the cells, passes out via drainage holes 25 and is pumped to a cell which is in a counter-current position relative to the direction of motion of the rotor via pump 26 and inlet pipe 23 (see flow Fig. 5).  When in fully "rich" condition, the miscella is withdrawn at a suitable point e.g. via pipe B1 in Fig. 5 after clarification by passage through a bed of solids in the rotor.  The movement of the cells is preferably continuous but may be intermittent.

[Class 8 (ii)] [See also Group XXVII] In a fluid-pressure-operated engine starter or like mechanical device of the kind comprising a piston movable rectilinearly by fluid pressure and rifled or screw-threaded means for converting the rectilinear motion into rotary motion, two pistons d, f are initially positioned with relation to each other so that an initial capacity is obtained within the apparatus. The piston d moves in a pressure cylinder c and is secured to a hollow shaft e externally rifled or screw-threaded throughout its length to engage a torque ring h. The piston f works in the plain interior of the shaft e, and is secured to an externally rifled or threaded sleeve g carrying a dog clutch member g<1> and co-operating with internal rifling in the end of the shaft e remote from the piston d. The torque ring h is mounted between the pressure cylinder c and a torque cylinder a, and a spring i normally retains the parts in the position shown, a flange k on the sleeve g being in engagement with stops l in the cylinder a. The device is actuated by compressed air or gas, or by gases from the firing unit described in Specification 441,053, [Group XXVII]. On admitting the gases by an inlet p to the space within the shaft e, the clutch g<1> engages the shaft to be driven and the flange k bears against a thrust bearing n. Axial movement of the piston d then effects rotation of the clutch sleeve g.

Title: Improvements in and relating to rontgen-ray apparatus
IPC: H05G1/50
Filed: 1921-01-06
Abstract: 156,678. Reiniger, Gebbert, & Schall Atk.-Ges. Jan. 12, 1916, [Convention date]. Addition to 156,554. Transformers; commutator switching-arrangements.-Relates to a modification of the current supply system described in the parent Specification. The rotating conductor of that system controlling the intermittent current impulses is replaced by a spark gap, the length of which is adjusted that it is only broken down by a voltage not far short of the maximum value of the available voltage supply. The slow rays and soft R÷ntgen rays occurring at low voltages are thereby largely suppressed giving a hard and homogeneous radiation. To increase still further the suddenness of the formation and extinction of the spark, the spark gap may be immersed in hydrogen-containing gases or vapours; or several spark gaps in series may be used: or again a part of the spark gap electrodes may be caused to rotate in synchronism with the E.M.F. of supply or may otherwise periodically be made to approach and' recede from the remaining electrodes.

Title: Improvements in and relating to stripping waste yarn from bobbins
Inventor: COLES WALTER VALANTINE
IPC: B65H73/00
Filed: 1951-01-11
Abstract: 694,588. Bobbins; stripping waste yarn from bobbins. COURTAULDS, Ltd. Jan. 10, 1952 [Jan. 11, 1951], No. 793/51. Class 120(iii) A flanged bobbin 1, Fig. 4, has in the yarn supporting face of the barrel a single groove 5 parallel to the bobbin axis, and a hole such as 6 in both flanges corresponding to the grooves so that a cutter 8 can be passed through the hole in one of the flanges, along the groove to cut the waste layers of yarn on the bobbin and into or out through the hole in the other flange. Groove 5 may be semi-circular in cross-section and merge i n t o the holes in the flanges, which holes may be tapered inwardly. The cutter may have an inclined cutting edge 9 or one of fish-tail shape as shown, and may be operated by hand or by machine. As shown, Fig. 8, the bobbin is inserted between two hollow centres 10, 11 which engage the tapered holes 6, 7 in the bobbin flanges. Depression of a pedal draws down a rod 14, against a spring 23, so that a cutter 8 carried by rod 14 descends through centre 10, hole 6, groove 5, hole 7 and centre 11. The severed helices of waste yarn are sucked away through a funnel 19 the mouth of which contacts the bobbin barrel and has the same curvature, thereby serving to orient the bobbin with respect to the cutting edge 9 of cutter 8. When the bobbin is removed, centre 10 moves down under the pressure of a spring 15 so that a guide 20 carried by the centre engages and depresses a plunger 21 into a recess in rod 14, thereby preventing cutter 8 from being operated until centre 10 is raised again by the insertion of another bobbin. Specifications 4170/15, 283,748 and 306,206, [all in Class 120(iii)], are referred to.
