Title: Improvements in and relating to means for the hydraulic transmission of power
IPC: B23B47/22
Filed: 1931-04-29
Abstract: 378,003. Hydraulic transmission of power. NATIONAL AUTOMATIC TOOL CO., Richmond, Indiana, U.S.A.-(Assignees of Schafer, R. A. ; 211, South 15th Street, Richmond, Indiana, U.S.A.) April 29, 1931, No. 12681. Convention date, Sept. 26, 1930. [Class 69 (ii).] Hydraulic mechanism for reciprocating a machine part, e.g. the head of a multipledrilling machine, comprises a control valve adapted to be moved automatically from one neutral position to another through a series of operative positions ; the movement is effected automatically as described in Specification 378,009 under the control of the machine part after the depression and release of a pedal, which may afterwards be depressed to effect reversal. The mechanism comprises an operating cylinder supplied from a pump unit of variable output, which may be as described in Specification 270,715, [Class 69 (ii), Hydraulic presses &c.], the pump and connections with the cylinder being controlled by a valve 21, Fig. 5, the spindle of which is connected to a member 45, Fig. 2, acted on by a spring 51 tending to urge it to the left. The valve is shown in Fig. 5 in its initial neutral position to which it has been moved from its final neutral position, against the action of the spring 51, by the depression of a pedal linked to a lever 97. The release of the pedal allows the spring to move the valve to the left, until a step 61 on the member 45 comes into contact with a member 62, the machine part being thus given a rapid forward motion. The machine part carries stop members which act successivelv on a lever 90 to raise the member 62 ; at each lift the valve 21 is moved to the left to bring the next step on the member 45 into contact with the member 62. The valve is thus moved successively through positions for giving the machine part a slow forward and rapid reverse motion to a second neutral position. Depression of the pedal while forward motion is in progress causes a cam surface on the lever 97 to act on a lever 92 to lift the member 62 against spring action sufficiently far to enable the valve 21 and member 45 to move into the position for effecting reverse motion ; at the end of the reverse motion, the appropriate stop acts to allow the valve to assume its final neutral position.

Title: Improvements relating to writing instruments
IPC: B43K24/08
Filed: 1957-04-18
Abstract: 804,903. Writing instruments. SCRIPTO, Inc. April 18, 1957 [Dec. 31, 1956], No. 12728/57. Class 146(3) A retractable writing instrument, e.g. a ball-point pen, having a rearwardly biased writing unit 16, includes a freely floating latch member 54 longitudinally slidable within the barrel to the rear of the writing unit and in front of a plunger 70 slidably carried in the rear end of the barrel, said plunger :and latch member having the adjacent ends thereof formed for contact so that each successive depression of the plunger rocks the latch member transversely in the direction opposite to that of the preceding depression, and means within the barrel for engaging the latch member in the projected and retracted positions of the writing unit 16. The plunger 70 is rearwardly biased by a spring 74 and has inclined faces 80, 82 at its front end for alternate engagement with corresponding cam surfaces 56, 58 respectively of the latch member 54. The writing unit 16 is held in projected position, as shown, by the engagement of a latch arm 60 of the member 54 with a latch shoulder 44 on a channel-shaped insert 42, the rearward bias of the unit causing the member 54 to rock laterally until it contacts the insert 42 at 68 also. When the plunger 70 is depressed the face 82 engages the cam surface 58 of the latch member, causing the member to rock about the fulcrum 68 and thus disengaging the latch arm 60 from the shoulder 44. Pressure on the plunger being released, the unit 16 and latch member 54 are carried backwards by a spring at the front end of the barrel, until a latch arm 62 on the member 54 engages with a shoulder 46 on the insert 42. The spring 74 carries the plunger 70 backwards until it no longer contacts the member 54 which then rocks and contacts the insert 42 at 67 also. When the plunger is depressed a second time, the face 80 contacts the cam surface 56 and the latch member and unit 16 are carried forwards until the latch arm 60 is forward of the shoulder 44: the member then rocks about fulcrum 67 and the arm 60 engages the shoulder 44. A plug 28 fitting into the end of the unit 16 has an axial passage and is closed by a cap 32, venting being provided by external grooves in the plug. Specification 801,910 is referred to.

Title: Aircraft convertible from rotary- to fixed-wing flight and back
IPC: B64C29/00
Filed: 1966-03-23
Abstract: 1,146,468. Convertible aircraft. SOC. CHARLES MARCHETTI. 23 March, 1966 [8 April, 1965], No. 12884/66. Headings B7G and B7W. A convertible aircraft comprises a bladed rotor 3 capable of being driven by a jet propulsion unit 2 for vertical take-off and capable of being fixed with respect to the aircraft's fuselage so as to act as a fixed wing in normal forward flight, the blades being provided with movable flaps 9, 8 at both their leading and trailing edges. The rotor is preferably propelled by the reaction. of jet streams discharging through nozzles 7 fixed one to the end of each rotor blade. Fluid under pressure is supplied to each nozzle 7 through a conduit in the fuselage communicating at one end with the by-pass passage of the jet-propulsion unit 2 and at the other end with passageways in the blades leading to the nozzles 7. As shown, the rotor has three equi-spaced blades 6, whereby by fixing one of the blades in a longitudinal direction with respect to the fuselage, the other two blades form a swept wing. Each blade is symmetrical in cross-section with respect to the vertical median plane through its longitudinal axis, Fig. 3 (not shown). During vertical flight the incidence angles of the flaps 8, 9 of each blade are varied both generally and cyclically by a single or double swash-plate arrangement commonly used to control the cyclic and general pitch of helicopter blades, Fig. 4 (not shown). In forward flight the flaps 8, 9 on the fixed swept wing are actuated by operating the cyclic pitch control. The flaps may also be operated by electronically controlled servomotors mounted on the blades. When changing over from vertical to forward flight the rotor is rapidly stopped by discharging fluid from nozzles facing in the opposite direction to the nozzles 7 and simultaneously operating a mechanical brake, followed by locking thereof to a retractable or non-retractable support 22 carried by the fuselage 1. Alternatively the nozzles 7 may be provided with thrust deflectors.
