Title: Improvements relating to lubricating systems
IPC: F16N27/00
Filed: 1925-11-19
Abstract: 243,367. Tecalemit, Ltd., (Assignees of Soc. Anon. des Etablissements TÚcalÚmit). Nov. 19, 1924, [Convention date]. Actuating by liquid pressure; single-acting suction-valveless bucket and piston pumps; two or more barrel in series.-A lubricating system comprises a chamber 4 in which a piston 5 is adapted to be moved against a spring 6 by lubricant supplied under pressure through a pipe 16. When the piston 5 clears the port 10, the lubricant enters a chamber 3 and displaces a piston 11 which is open on the outer side to atmospheric pressure. When the pressure supply is cut off, the spring 6 returns the piston 5 so that lubricant may flow from the chamber 3 into the chamber 4. On the next forward stroke of the piston 5, the lubricant in, the chamber 4 is forced through the delivery valve 15 to the noint to be lubricated. The piston 5 is controlled by stops 7, 9. One or more additional devices for supplying lubricant to other points may be supplied by the pipe 16a. In another form, the piston 5 is of differential form. so that the pressure of the lubricant in the delivery pipe 14 may be higher than that in the supply pipe 16. In the form shown in Fig. 3. the piston 5 acts as a valve only, moving forward under the pressure of the incoming lubricant to open the port 10 and admit lubricant to the chamber 3, from which it is discharged by the spring-pressed piston 11 into the pipe 14 when the piston 5 is returned to bring the reduced portion 18 into register with the port 10 and chamber 2. In the form shown in Fig. 4. the piston 5 is moved bv the lubricant into contact with the stop 9, the valve 18 then opens and admits lubricant to the chamber 3, from which it is discharged to the pipe 14 by the piston 11 when the piston 5 returns and opens the chamber 2. In the form shown in Fig. 5, when the piston 5 is moved against the stop 9, the lubricant passes through the channels 21, or into an annular chamber 3, from which it is discharged to the chamber 2 by the annular face of the piston when the latter is returned by the spring 6. In this case the delivery pressure is greater than the supply pressure. In the Specification as open to inspection under Sect. 91 (3) (a) the following additional forms are described: In the form shown in Fig. 6 (Cancelled), the lubricant in the chamber 3 passes through a clearance 10 between the chamber 2 and the piston 5 during the return strode of the latter, and during the forward stroll it is delivered past a valve 15 to the pipe 14. In another form, a leak port is arranged in the larger portion of a differential piston for the passage of the lubricant from the chamber 3 to the chamber 2. In another form, a spring-pressed valve is arranged in the piston 5 which carries a tubular piston of smaller area. This subject-matter does not appear in the Specification as accepted.

Abstract: 643,368. Driving gear. NORDBERG MANUFACTURING CO. Nov. 4, 1947, No. 29389. Convention date, Aug. 26, 1946. [Class 7(ii)] In a radial cylinder engine wherein each piston 28 is connected by rods 31 to a ring 32 journalled on but prevented from rotating about a crank-pin 22 on a crank-shaft 14, the rods 31 are arranged so that when a piston 28 is in its dead-centre position, the rod 31 is inclined at an angle to the cylinder axis, in a direction opposite to the crank rotation, said angle not being great enough to cause reversal of the torque on the ring 32. Rotation of the ring 32 is prevented by a planetary gear train comprising a gear 46 integral with the ring 32 and meshing with a planet gear 51 on a shaft 52 journalled in a balancing-mass 26 integral with the crank-throw 24, a second planet-gear 49 on the shaft 52 meshing with a sun gear 47 bolted to the detachable crank-case cover 12. The gears are helical, and the ratio of the planet 51 to gear 46 is the same as that of the planet 49 to 'the sun: wheel 47.

Abstract: 654,339. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., MUNNS, J. G. W., and TRICKETT, E. S. Nov. 15, 1948, No. 29647. [Class 38 (iv)] For maintaining a short-wave oscillator 1 at a predetermined frequency, its output is mixed in a rectifier 2 with waves of lower frequency from a source 3 which are wobbled in frequency by a device 4. The mixer output is fed to a resonant device 5 sharply tuned to the sum or difference frequency produced by the mixer 2. The device 5 is in resonance with its input twice in each wobble cycle and at these instants the device is excited and gives a D.C. pulse in the circuit of a rectifier 6 which pulses are amplified at 7 and applied through a two-way switching arrangement 8 to a frequency adjuster 10 associated with the controlled source 1. The switch 8 is operated at the wobble frequency by the source 9 controlling the device 4, and serves to direct the pulses from the amplifier 7 to alternative channels arranged to vary the frequency in one direction or the other respectively. If the source 1 is operating at the predetermined frequency, the pulses occur at the moment of switching at 8 and produce no effect. If the frequency is too high or too low, the pulses occur when the switch 8 is in the position appropriate for correcting the frequency. The resonant device 5 may comprise a cavity resonator or a co-axial line section, and the switch 8 may be a valve gating- circuit. If the mid-frequency of the source 3 is liable to drift, its output may be fed to a sharply-tuned acceptor circuit, the output of which is rectified and used to synchronize the switch 8. In a modified circuit (Fig. 2, not shown), the frequency of the source 1 is reduced by heterodyning with a stabilized source before it is mixed with the output of the frequency-wobbled source 3. The resonator 5 may in this case comprise a crystal filter, or a tuned circuit with lumped impedances.
