Title: Improvements in carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1936-08-17
Abstract: 462,105. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH. Aug. 17, 1936,.No. 22637. Convention date, Aug. 24, 1935. [Class 7 (iii)] In a carburetter in which the supply of fuel is controlled by a valve operated by a diaphragm formed in one wall of a fuel chamber and loaded by a spring tending to open the valve, a mechanism actuated by the throttle valve when that valve is nearly closed, renders ineffective the action of the spring against the diaphragm. A fuel nozzle 4 is controlled by a needle 5 linked to an anterior throttle 3 and supplied from a chamber 10 having in one wall a diaphragm 12 exposed to atmospheric or less pressure in a chamber 14. A spring 19 presses the diaphragm 12 inwards to open the fuel supply valve 13 and a weaker spring 23 tends to close it. Between the spring 19 and the diaphragm 12 a cap 20 is mounted on a rod 21 slidable in a guide 22 and a head 30 on the rod is engaged by an arm 28 of a lever 27, connected to the throttle valve lever 6, when the throttle is closed, downward movement of the rod 21 withdrawing the spring 19 from the diaphragm : the spring 23 is then counterbalanced by the suction during idling and closes the fuel valve 13 when the engine is stopped. To overcome the effect of friction between the rod 21 and its guide 22, the opening spring 46, Fig. 4, engages a cup 43 slidable on a rod 40 formed with a head 42 adapted to engage the cup 43. The lower end of the rod 40 is connected to a spring pressed arm 32 pivoted on the throttle valve spindle 33 and engaged by an adjustable stop 49 on the throttle control lever 48. Specification 378,025 is referred to.

Title: Improvements in warp knitting machines
IPC: D04B27/00
Filed: 1966-05-24
Abstract: 1,120,136. Knitting-machines. G. E. BOAST and R. WOOLLETT. 22 May, 1967 [24 May, 1966], No. 23045/66. Heading D1C. The speed of rotation of the warp beam 5 or bobbins of a warp machine is increased in response to the increase in tension of the yarns as the beam or bobbins is or gradually depleted of yarn during knitting. This ensures that the rate of delivery of the yarns remains substantially constant. The yarns 4 pass over a deflector bar 6 attached to a leaf spring 7 on the tension rail of the machine and any abnormal deflection of the bar 6 due to an excessive increase in tension caused by the failure of the beam to increase speed in relation to the decrease in the effective diameter of the yarn wound thereon causes the bar 6 to engage a bolt 10 secured resiliently to a lever 8. The lever 8 is consequently pivoted to cause its further end to be raised and actuate a switch 23 operating a clutch in the drive of the beam whereby its speed is increased. The further end of the lever when it is raised disengages from contact with a rod 27 under the control of a spring 28 and piston 18 in an oil filled cylinder whereby the current energizing an electromagnet 21 is cut off. The action of the rod 27 is to gradually follow the end of the lever 8 such that after a time delay the circuit is restored and the current again supplied to the electromagnet 21 with the result that the arm 8 is again pivoted and restored to its normal position. The switch 23 is thereby disengaged and the clutch ceases to function whereby the beam is now rotated at an increased speed. An over-centre device in the form of a notched disc 15 and spring loaded plunger 13. retains the lever 8 in its two pivoted positions until it is caused to be deflected to the other by the yarn tension or electromagnet. Alternatively an electronic time relay may be used instead of the hydraulic arrangement to control the electromagnet 21.

Filed: 1948-09-03
Abstract: 653,201. Pen and pencil holders. HUTCHESON, J. W. Sept. 3, 1948, No. 23298. [Class 146 (iii)] In a holder 1 for a pencil and a pen the latter are disposed on the opposite faces of an intermediate plate 9, and the pencil comprises a fork A slidable in guides 17 on the plate against the action of a spring 20. On the plate 9 is a fixed guide 11, a movable guide 12, and a fixed guide 14 for a pencil lead 31. The free ends 7, 8 of the fork A pass through the guides 11, 12 and are adapted to grip the lead 31. Wedge-shaped projections 32, 33 on the ends 7, 8, on the forward movement of the fork to feed the lead, displace the guide 12 until the latter abuts stop shoulders 34 on the plate 9, and the continued movement of the fork causes the projections 32, 33 to move beyond the guide and thus allow the ends 7, 8 to spring apart and release the lead 31. On retraction of the fork A by the spring 20, the guide 12 is retracted by the projections 32, 33, and the ends 7, 8 engage the lead to retract the latter for a distance which is shorter than the forward feed. The fork A is moved by a member 23 adapted to abut the fork and project beyond the rear end of the casing 1. The pen unit comprises a casing 15 which is tapered at the front end and provided with a ball writing point.

Filed: 1958-07-22
Abstract: 852,878. Friction clutches. FORD MOTOR CO. Ltd. July 22, 1958 [July 22, 1957], No. 23537/58. Class 80 (2). An hydraulically engaged clutch for use in planetary change-speed gearing comprises a rotating servo cylinder and a piston operative to cause clutch engagement, a valve carried at the periphery of the cylinder being opened by centrifugal force against the residual pressure in the servo when operating pressure is no longer supplied thereto, so that centrifugal force acting upon the liquid remaining in the cylinder cannot cause partial clutch engagement. In one form, the valve comprises a piston 112, Fig. 1, moved radially inwards to close an exhaust port 116 by the pressure acting on a piston 92 in a rotating servo cylinder 90 and transmitted through a port 118 to the base of the valve. Centrifugal force acting on the piston 112 is unable to overcome the pressure supplied through the port 118. When pressure is no longer applied to the liquid acting upon the servo piston 92, the valve piston 112 is moved outwards by centrifugal force, and the exhaust port 116 opens so that the residual pressure in the servo cylinder 90 is vented. The exhaust port 116 may include a precalibrated orifice, the rate of flow permitted by the exhaust port in any case being less than the rate of flow of liquid to the servo cylinder 90. When it is desired to re-engage the clutch, liquid supplied to the servo cylinder acts through the port 118 to move the valve piston 112 radially inwards against centrifugal force and closes the exhaust port 116. In another form, the valve comprises a ball 112<SP>1</SP>, Fig. 2, in a servo piston 921, a passage 118<SP>1</SP> leading liquid under pressure from the servo cylinder working space to the back of the ball which is thereby moved inwardly against centrifugal force to close a port 110<SP>1</SP>. When pressure is no longer supplied to the servo cylinder 90, the valve ball 112<SP>1</SP> is moved outwards by centrifugal force to the position shown, opening a passage 116<SP>1</SP> through which liquid in the servo cylinder 90 is vented to exhaust.
