Title: Improvements in or relating to pressure lubricators
IPC: F16N13/10
Filed: 1934-04-24
Abstract: 423,551. Lubricating-pumps. BLISS, J., 30, Cheapside, London. April 24, 1934, No. 12367. [Class 102 (i)] A lubricator comprises an oil container 3 closed by a hinged lid 7 and provided with a filter 11; heating medium may be passed through a passage 13. Two rows of cylinders 14 are mounted in the container 3, each cylinder communicating with a delivery pipe 15 and having an inlet 16. The plungers 17 are mounted on a member 6 reciprocating within the container, each plunger being carried by a flanged sleeve 18 supported at 40 on the member 6; the sleeve covers the inlet 16 on each downstroke. The top of each plunger 17 is engaged by a screw 20 mounted in the member 6 and having grooves engaged by a spring-pressed locking plunger 22. The member 6 has an extension 5 guided in a well 4 of the container, and is reciprocated by an eccentric 24 mounted on a shaft 25 extending through the container; a casing surrounding a ratchet wheel on the end of the shaft and having a spring-pressed pawl engaging therewith, is oscillated to rotate the shaft; a wheel is also provided for handoperation. A plunger slidably mounted in a plug 30 screwed into the member 6 is formed at its head as a tappet face which is pressed against the eccentric 24 by a spring 31 under considerable compression, whereby wear is taken up, lost motion is prevented and a braking action is exerted on the eccentric. A tappet may be similarly mounted below the eccentric 24. The tappet may comprise a flat head pivoted to a stem and carrying rollers engaging the eccentric 24 ; the spring 31 may be replaced by an oil chamber surrounding the stem and having a non-return valve which only permits entry of lubricant into the chamber.

Abstract: 1,041,144. Variable-pitch marine propellers. T. HINDMARCH. March 2, 1965 [March 25, 1964], No. 12556/64. Heading B7V. A mechanism 29 to 37 (the only Figure, not shown) for controlling the pitch of a marine propeller is coupled to a lever 27, which is connected at 38 to a governor-controlled fuelregulator of a Diesel engine driving the propeller, by a hydraulic transducer or movement-sensing device A and a hydraulic servo-motor or correcting device B to render the pitch appropriate to the output of the engine. The transducer comprises a spool valve-member 2 coupled by a rod 1 through a spring-loaded safety-link 41 to the lever 27, said member being slidably lodged in a cylindrical sleeve 4 which is axially movable in a stationary cylinder against the action of a compression spring 5. The sleeve is closed at one end by a plug 11 whereas the cylinder is connected by a passage 12 and a tube to an inlet passage 13 in the motor B. In operation, pressurized oil supplied to an annular space or recess 7 in sleeve 4 through a passage 6 enters a channel 10 through transverse ports 9 in the sleeve when the valve-member is moved by actuation of the lever 27. Pressure in the channel 10 is communicated to the plug 11 so that the ports 9 are closed by the sleeve and to the lower end of a spool valve-member 15 in the motor B, the member 15 being raised against the action of a spring 16 to allow pressurized oil to enter spaces 19, 25 on either side of a piston 20 from a passage 14 through a flow-restricting orifice 18 and a passage 23, respectively. When the lever 27 is actuated so as to displace the valve-member 2 towards the plug 11, the oil in the channel 10 is released to a space containing the spring 5 through the ports 9, and oil in the space 19 is released through the orifice 18 and a passage 39 whilst the piston 20 is displaced upwardly by the oil in the space 25. Movement of the piston in either direction effects a corresponding change in the position of a sliding member in a slotted link 29 forming a part of a manual-control lever 30 in the pitch-controlling mechanism.

Abstract: 653,910. Grinding cams. CESKOMORAVSKA-KOLBEN-DANEK, NARODNI PODNIK, and JANATKA, J. May 7, 1948, No. 12673. Convention date, May 8, 1947. [Class 60] [Also in Group XXII] In a method of manufacturing a cam co-operating with a follower and yielding a continuous acceleration diagram of the follower, the working contour of the cam is formed by a grinding wheel connected to a flexible tension member which cooperates with a guiding surface of a pattern, the guiding surface being spaced uniformly from the evolute of the working contour of the cam. The cam V, Fig. 5. is formed by means of a grinding wheel B the axis of which is fixed to one end of a steel tape p, the other end of which is fixed between parts T<SP>1</SP>, T<SP>2</SP> of a pattern, the cam being rigidly connected to the parts T<SP>1</SP>, T<SP>2</SP>. The guiding surfaces K<SP>1</SP>, K<SP>2</SP> of the parts T<SP>1</SP>,  T<SP>2</SP> are spaced uniformly from the evolute of the cam contour by a distance equal to half the thickness of the tape p. The cam and parts T\ T<SP>2</SP> are mounted on a lever N pivoted to a fixed axis Q and are oscillated about a point O by means or a crank AS and connecting rod AD. By means of this mechanism the point of contact M of the grinding wheel with the cam moves along the desired path. The tape is tensioned by means of a spring Z. In a modification, Fig. 6, a roller-follower cam V<SP>2</SP> is formed with the aid of a master cam V<SP>1</SP> formed as described in connection with Fig. 5. The cams are rotated at the same angular velocity and have the centre lines of their lobes inclined at the same angle to the plane containing the cam axes. A spring-pressed slide block E engages the cam V, and a grinding wheel B engages the cam V<SP>2</SP>, the grinding wheel and slide block being mounted on a common slide H which is moved, by means of the master cam, in a direction perpendicular to the cam axes.

Title: Improvements in and relating to aircraft
IPC: B64C27/54
Filed: 1934-04-27
Abstract: 437,521. Aircraft with rotary-wing systems. WILKENING, F. W., Arlington Road, Penn Valley, Pennsylvania, U.S.A. April 27, 1934, No. 12807. Convention date, Feb. 2. [Class 4] A rotating wing system for aircraft comprises a hub 19 on which is mounted a plurality of blades 18 free to vary their pitch, to lag with reference to the hub axis and also to swing in planes through the hub axis, variations in pitch being correlated to variations in lag but swinging in the said planes causing no variation in pitch. Further, the variations in lag are correlated to variations in pitch without the use of intermediate members between the blades 18 and stubs 20 mounted on the hub 19. In one form, the hub member 19 is driven from a crank-shaft 41 from a radial liquid - cooled engine through a shaft 36, reduction gearing 42 ... 42<c> and a freewheel clutch 43 the outer casing of which may form a brake drum. The rotor blades are each hinged to the hub member by horizontally arranged pins 22, the tubular stubs 20 of the blades being shaped as shown to provide stops 25, 25<a> to limit movement of the blades. A tubular spar 26 of each blade is mounted on vertically disposed trunnions 27, journalled in the stub 20 and a thrust-bearing 30 facilitates rotation of the blade about its longitudinal axis relative to the stub 20. The blade 18 is thus free to lag in its plane of rotation and to take up a position of equilibrium under the effects of centrifugal force and drag. This lagging of the blade is adapted to change its incidence automatically through a bevel-gear segment 33 on the spar 26 which meshes with a bevel-gear segment 34 secured to or formed integral with the stub 20. The segments may be replaced by pin and slot or other linkage. Angular displacement of the blades about their longitudinal axis is limited by stops, e.g. by providing blank portions on the segments.

Title: Improvements in or relating to rear springing for motor cycles
IPC: B62K25/04
Filed: 1942-09-11
Abstract: 564,414. Spring frames for motor cycles. NORTON MOTORS, Ltd., and FRANKS, E. M, Sept. 11, 1942, No. 12873. [Class 136 (iii)] [Also in Group XXXII] Relates to rear springing for motor cycles of the type in which the wheel spindle is carried by members slidably mounted at each side of the wheel on substantially vertical rods d secured to or forming part of the framing a, b, the load being supported by helical compression springs e on the upper parts of the rods. According to the invention, the upper end of each spring abuts a member, e.g. a sleeve g, which is slidable on the rod d and is located by an angularly - movable cam or the like having a number of steps of progressively - varying height measured from the axis of the cam, by engagement of which with the sleeve g the compression of the spring may be varied. As shown, the sleeve g is secured by pins passing through a slot in the rod to a plunger h slidable in the rod and engaging the cam which is rotatable on a pin k by an integral lever handle l or by a hand wheel m. A fork end (not shown) carrying one end of the wheel spindle, is slidable on the rod between the spring e, which thus takes the load on the wheel, and a lighter rebound spring f. An indicator may be provided to show which step on the cam is in use. In a modification, the spring abutment consists of a sleeve which is slidable on the rod d and engages identical stepped cams lying on opposite sides of the upper end of the rod and formed on the limbs of a forked lever pivoted on the upper frame member a. To prevent accidental movement of the cams, small projections on the sleeve engage complementary recesses in the steps on the cams.

Title: Rotor for convertible aircraft
IPC: B64C27/615
Filed: 1965-03-26
Abstract: 1,081,331. Helicopter rotor blades. BÍLKOW G.m.b.H March 26, 1965 [March 28, 1964], No. 12953/65. Heading B7W. A helicopter rotor blade has a spar and a trailing edge portion mounted on the spar and movable relative thereto to be retracted. The blade is intended for use on convertible aircraft and is foldable about a drag hinge (Figs. 9 and 10, not shown). In one embodiment a flexible skin 2 is mounted on a series of ribs 3 which may be drawn together into a sleeve (29, Fig. 2, not shown) at the root of the blade. The ribs comprise flanged portions (3a, 3b) held together to clamp the ends of individual skin portions. The skin may be thinned locally to facilitate its folding concertina-fashion. The ribs engage guides on the spar (1 or 47), and the retractable portion may be the trailing edge alone, the spar forming the leading edge, or both leading and trailing edges. The ribs are pulled towards the root by cables (4, Figs. 3-5, not shown) with stops (22) which engage slots (16) in the ribs. The ribs carry control plates (21) with cooperating projections (19) and recesses (20), the projections (19) of one rib, or a similar projection at the root, engaging a recess of a rib drawn towards it to deflect the stop 22 into a hole (23) so that the cable (4) can continue to draw ribs further outboard when inboard ribs have reached the root. The ribs are then held together by hooks and pins (25, 27), the hooks (25) being rotated into engagement with a pin (27) by an arm (26) engaging an adjacent rib on the outboard side. Thus the outboardmost rib is not secured and on rotation of the blade it moves outwardly, the other ribs following in succession. This extension may be helped by weighting the movable portion of the blade, or by further cables. In another embodiment the skin may be formed of spanwise extending strips (Fig. 6, not shown) which fold between the ribs. Alternatively, there may be a flexible trailing edge and in one embodiment (Fig. 7, not shown) a flexible leading edge or the trailing edge may comprise rigid sections hinged together (Fig. 8, not shown). These engage guides on the spar (1 or 47) and are drawn into the rotor head and rolled up.

Title: Improvements in or relating to solid fuels and methods of making them
IPC: C10F5/06
Filed: 1953-05-08
Abstract: Peat is treated (see Group XII) to produce an absorbent peat charcoal and a combutible gaseous mixture which latter is used to produce lampblack.  The treatment comprises washing the peat, forming a coherent peat web, which travels through a solvent bath, e.g. toluol, xylol, and chlorinated hydrocarbons such as tetrachloroethylene, which is kept at a moderate temperature, e.g. the vaporizing temperature of the solvent.  This solvent removes waxes and other ingredients which would render the subsequently evolved gas unsuitable for lampblack production.  The peat web passes to a calciner which disintegrates it and removes water &c., and afterwards to a higher temperature calciner where some volatiles are driven off and then to a third, still higher temperature, calciner where is evolved a gaseous mixture hydrogen, saturated carbon compounds such as methane, and unsaturated gaseous hydrocarbons, e.g. ethylene. These gases are produced in excess of the fuel required to supply heat to the entire process, the excess being used for lampblack production.  The lampblack may be briquetted with a binder and coked to form a substitute for graphite, e.g. for electrodes.
