Abstract: 642,765. Duplex pumps. WERKSPOOR, N. V. Dec. 15, 1947, No. 32996. Convention date, Aug. 2, 1946. [Class 122(ii)] In a crankless duplex pump in which one driving piston is at mid-stroke when the other changes direction, each driving cylinder is provided separately with a valve chest containing a distributing valve operable by driving means operatively connected to the piston rods of both cylinders, the driving means being adjustable to permit continued operation of one of the distributing valves by the piston rod of its associated driving cylinder independently of and upon stoppage of the other driving cylinder. Pump pistons 4, 4a are driven by pistons 2, 2a reciprocating in steam cylinders 1, 1a and the distributing valve 8, 8a for each cylinder is operated by a pivoted lever 5, 5a which is directly engaged by the piston rod 3, 3a of its associated cylinder and has its pivot 9, 9a displaced, through a linkage system, by movement of the lever associated with the other cylinder. In the event of stoppage of one pump unit 2, 4a the other pump unit 2, 4 may operate as a simplex pump by adjusting the pivot 9 of lever 5 to its mid position by displacing the piston rod 3a. Movement of lever 5 of the operating pump 2, 4 causes the pivot 9a of the lever 5a to oscillate and the latter swings about a fixed pivot on piston rod 3a. The pivot 9 of lever 5 is oscillated due to the swinging of the lever 5a but such oscillation is slight and has no influence on the steam distribution in the cylinder 1.

Abstract: 1403118 Drawing sheet glass LIBBEYOWENS-FORD CO 12 July 1973 [31 July 1972] 33275/73 Heading C1M The temperature profile across a body of molten glass is controlled by periodically scanning across the glass body with a temperature sensing means so as to determine the temperature of successive ones of a plurality of zones across the glass body, and thermally conditioning the molten glass in each of a plurality of second zones corresponding to the first zones but upstream thereof in response to the temperatures sensed. As shown, in a sheet glass drawing apparatus, temperature sensing device 36 is provided above the drawing apparatus. The device 36 includes a pyrometer 37 mounted for angular movement so that it can scan the meniscus 23 formed in the drawing operation. Movement of the pyrometer is achieved by the action of a drive mechanism 80 which includes a reversible motor 82 and actuating arms 101, 102 which co-operate with limit switches 103, 104 to reverse the motor 82 when the pyrometer has reached the end of its scan. Thermal regulation is achieved by a lip-tile 24 that includes a tube 105 formed of a thermally conductive material such as stainless steel. A tubular member 108 is mounted within the tube 105, and is divided into a plurality of compartments 111- 116 each corresponding to one of the second zones. Each compartment is individually supplied with cooling air from plenums situated at each end of the cylindrical member 108, entry of air into a particular compartment being controlled by a corresponding solenoid valve 136. The air discharges through perforation 138 in the wall of the cylindrical member 108 to impinge on the interior of the tube 105. The operation of the solenoid valves is controlled by signals from a control circuit which compares the voltage produced by the pyrometer which represents the temperature of any given first zone with a voltage representing the desired temperature thereof.

Title: Improvements in reciprocating pumps
IPC: F04B1/18
Filed: 1932-11-29
Abstract: 406,106. Fuel pumps. AIVAZ, J., 20, Rue du Retrait, Paris. Nov. 29, 1932, No. 33757. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 8, 1933.] [Class 102 (i).] In a fuel pump in which pistons 6, Fig. 1, parallel to the driving shaft 9, are reciprocated by an inclined disc 8 the liquid is distributed by a disc 70, which is given an eccentric movement by means of a crank-pin 76 on the end of the shaft 9. The disc 70 is connected by a metallic bellows 72 to a disc 71, which bears against the inner surface of the end cap 4, the discs 70, 71 being pressed apart by a spring 80, which yields and permits by-passing of the discharge in the event of excess pressure. The pin 76 is surrounded by a sleeve 88, which engages bores in the hubs 73, 74 of the discs 70, 71. The pin 76 and the sleeve 88 have spherical ends. The suction takes place from a pipe 23 through ports 81 in the hub 74 and ports 79 in the valve 70, rotation of the valve being prevented by means of pins 83 on the disc 71 engaging circular recesses. The discharge to the exterior of the bellows 72 and to a passage 24 is controlled by ports in the valve 70, or by the outer periphery of the valve, as shown. In a modification suction and discharge are controlled by the inner and outer peripheries of the valve, respectively, means for preventing rotation of the valve being dispensed with. The Specification as open to inspection under Sect. 91 comprises also the following modifications. In a pump as described above the distribution is effected by a cylindrical valve 16, Fig. 1 (Cancelled) driven by a feather and groove engagement with the end of the shaft 9. Suction takes place through the interior of the valve to a port 21 and the passages 13 leading to the cylinders, the discharge taking place through a passage 20 and groove 19 on the exterior of the valve to the discharge passage 24. A by-pass valve 29 is carried by a diaphragm or bellows 30, the upper surface of which is acted on by a spring 34 and the pressure in the engine intake manifold through a pipe 33. Lubricant supplied under pressure by a passage 45 in one cylinder is picked up by a pocket 44 in the corresponding piston and carried to a recess 36 in the cylinder, from which it passes by a passage 37 and chamber 38 to recesses in the other cylinders. The lubricant acts as a piston seal. Excess lubricant passes by a check valve 42 to the cam casing. The disc 8 may be mounted on ball bearings on the shaft 9, or may be pivoted on the shaft and adapted to yield against the action of a spring in the event of excessive discharge pressure. As shown in Fig. 4 (Cancelled) the cam disc 8 is loosely mounted on a sleeve 60, which can rock on a spherical bearing 61 on the shaft 9 against the action of a spring 51. The sleeve 60 is driven by a projection 62 carried by the shaft. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,218,992. Reciprocating pumps. CATERPILLAR TRACTOR CO. (N. Waddleton). July 16, 1968, No. 33798/68. Heading F1A. [Also in Divisions F2 and G3] In a fuel injection timing device, the injection timing is directly responsive to engine speed and load as reflected by manifold pressure. An axially fixed rotating cam-shaft 12 is connnected to a drive gear 14 by a coupling 18, a part 19 of which extends into the shaft 12 and is keyed therein against relative rotation, a helical spline connection 22 connects gear 14 and coupling 18. A plunger 31 attached to coupling 18, is connected to a spring- loaded diaphragm cup 30 in chamber 28 such that increase in pressure in the manifold 24 transmitted via conduit 26 to chamber 28 moves coupling 18 towards the cam-shaft 12; such motion causes advancing of the fuel injection as the helical spline connection causes rotation of the shaft 12 with respect to gear 14. In another embodiment Fig. 3 manifold pressure entering via a conduit 26<SP>1</SP> moves a plunger 31<SP>1</SP> toward the cam-shaft and causes a groove 44 to simultaneously connect passages 45, 46, allowing pressurized oil from a line 47 to be fed into a chamber 46 thus causes the coupling 181 to move toward the cam-shaft and advance the timing.
