Filed: 1962-02-19
Abstract: 941,680. Slip couplings; friction clutches. R. P. LEWIS. Feb. 19, 1962 [May 24, 1961], No. 6404/62. Headings F2C and F2U. To ensure complete surface lubrication and cooling of discs of a friction clutch or coupling, inner discs 21 and outer discs 25 are each provided with a series of uniformly or irregularly spaced slots 32, 35, the slots of at least one or both series being inclined to the radius whereby the slots in adjacent discs intersect to provide holes at the points of intersection for the axial passage of lubricant, the radial location of these holes constantly changing with relative rotation between the discs, to feed the entire disc surfaces. The centre hole of the outer clutch discs may be eccentrically arranged (Figs. 5 and 6, not shown), so that it wipes lubricant from the adjacent inner disc surfaces and creates a pumping action forcing the lubricant between the discs. As shown, the disc slots are open ended forming intermediate flexible segments which accommodate distortion due to heat or residual stress. The discs 21, 25 have a constant spring- engaging load and connect a shaft 11 through a casing and flange members 16, 12, to a shaft 10.

Title: Improvements in and relating to control devices for automobiles
IPC: F16H61/34
Filed: 1935-03-06
Abstract: 442,399. Controlling change speed gearing. AUTO UNION AKT.-GES., 110, Scheffelstrasse, Chemnitz, Germany. March 6, 1935, Nos. 7066 and 7067. Convention dates, March 6, 1934 and Nov. 24, 1934. [Class 80 (ii)] [See also Group XXXI] Change-speed gearing at a distance from the driver's seat is controlled by means of a floating rod 12, Fig. 1, connected at one end by a universal joint 11 to the gear lever 1 and at the other end by a pivot 15 to the gear selector lever 13, the rod being supported and guided only by these end connections. The selector lever 13 is mounted on a ball joint 14 and controls the gear selector forks 22-25. Its lower end preferably works in a gate 2. In the construction shown in Fig. 1, the gear lever 1 is pivoted at 4 to a lever 5, 8 pivoted at 7 to the chassis frame, so that when the lever is rocked in the direction of the arrow, the lever swings about 7 and slides the rod 12 axially, thereby rocking lever 13 and moving the selected gear fork axially. An arm 9 on the lever 1 is connected by a link 18 to an arm 20 on the rod 12, so that when the lever 1 is rocked in a direction perpendicular to the plane of Fig. 1, the lever swings about pivot 4 and rotates rod 12 about its own axis, thus rocking lever 13 to select another gear fork. A gate 21 may be provided for the lever 1. In the construction shown in Fig. 2, one end of the rod 12 is mounted in a casing 5a pivoted at 6a to the frame, and the gear lever 1 is pivoted at 3a to the casing, the lower end 9a of the gear lever being formed with a toothed sector 20b gearing with a pinion 20a on rod 12. Thus, when the gear lever is moved in direction A or B, the lever and casing 5a rock about pivot 6a and rod 12 is moved axially, and when lever 1 is moved at right angles to the plane of Fig. 2, the casing 5a is unaffected, the lever 1 rocks about pivot 3a and the rod 12 is rotated by the gearing 20b, 20a.

Title: Improvements in or relating to lubricators
IPC: F16N27/00
Filed: 1927-03-15
Abstract: 283,369. White, A. E., (Bowen Products Corporation). March 15, 1927. Actuating by liquid pressure; stroke, varying; two barrels in series.-In a system wherein a pump supplies lubricant to a branched conduit system 8, lubricant supplied to each branch depressing a piston 12, Fig. 4, arranged in a cylinder 3 so as to eject a charge of lubricant contained beneath the piston to an outlet 25 which may be provided with a non-return valve 18, an enlarged head 26 at the lower end of the piston stem 28 moves through the opening in an annular flexible washer 16 held against a shoulder 40 at the lower end of the cylinder by a spring 14 arranged between the piston and a metal washer 15, the adjacent edges of the washer 15 and shoulder 40 being rounded so that the inner edge of the washer 16 is movable to two oppositelyinclined positions to prevent outflow from the cylinder in one position and to permit such flow in the other position. The spring 14 normally maintains the piston 12 at the top of the cylinder 3, the inner edge of the washer 16 being inclined upwards. During the operation of the pump, lubricant passes into the space above the piston through a slot 27 in a nut 13 securing the parts of the piston assembly together and through grooves 2 in the upper end of the cylinder 3 to the space beneath the piston. The pressure of lubricant causes the washer 16 to be pressed tightly against the head 26, preventing outflow, and the unbalanced pressure on the piston causes the latter to move downwards until the grooves 2 are closed. Increased pressure acting on the whole area of the piston then causes the washer 16 to reverse to the position shown and the piston moves down until the head 26 contacts with the bottom of a chamber 5, ejecting the oil trapped beneath the piston. When the pressure in the system is relieved, the spring 14 returns the piston to its normal position and the space below the latter is again filled through the grooves 2, the upper rounded edge of the head 26 causing the washer 16 to reverse to its original position. One or more metal washers 94 may be placed in the bottom of the chamber 5 to limit the stroke of the piston. The pump may comprise a cylinder 44, Fig. 7, having inlet ports 45 communicating with a reservoir 43, a piston 46 being normally held at the top of its stroke by a. spring 47. A discharging spring 48 is compressed by downward movement of a member 49 which is locked in the depressed position by a catch 54. At the end of the stroke, a head 52 on the plunger rod 53 releases the catch 54 and allows the member 49 to return to its normal position.

[Also in Division G1] A common base transistor push - pull oscillator of the type having a feedback transformer with primary windings connected between the collectors and feedback windings connected between the emitters has a resistor in the emitter-base circuit to control the oscillator frequency. This resistor may be temperature sensitive so that the frequency varies with temperature. In Fig. 3 the base feedback current is controlled by resistor RB and current builds up in the output circuit until the transistor becomes unsaturated whereupon the conductive state of the transistors reverses and current builds up in the opposite sense. It is explained that the frequency of operation is independant of the supply voltage and that by including also capacitance in the common collector or emitter connections to by-pass load dependent current the frequency may also be made insensitive to load variations (Figs. 5, 6 and 7, not shown).
