Title: Improvements in clutches
IPC: F16D23/12
Filed: 1965-05-12
Abstract: 1,100,848. Clutch control; linkwork. BORGWARNER CORPORATION. 12 May, 1965 [28 May, 1964], No. 20085/65. Headings F2K and F2L. Automatic adjustment for wear is made in the control linkwork of a remote-spring motorvehicle clutch independent of the amount of free-play in the clutch pedal, by varying the length of an adjustable link 76. The link comprises a tie 12 formed with ratchet teeth 13 and received in a housing 10 carrying a pawl 14 and flanges 10a, 10b, and a guide 17 having teeth 18 and fixed to the transmission or clutch bell housing (not further described), along which guide a slide 20 carrying a spring 19 and formed with a flange 20a is moved. The clutch is maintained engaged by a stationary remote spring 54 acting on clutch engaging levers 31 through the linkwork and a clutch engaging bearing 47. As the friction lining material 45a, 45b on the clutch disc 43 wears, the housing 10 moves further to the right to fully engage the clutch, the flange 10a tending to move the slide 20 along the guide 17 by an equal amount, until the wear amounts to the equivalent of one tooth on the guide 17, when the slide is moved this amount. On next depressing the clutch pedal, the housing 10 is drawn to the left until a screw 24 in flange 10b abuts the flange 20a when, since the slide cannot move to the left due to spring 19 and teeth 18, the tie 12 is withdrawn from housing 10 by one tooth width, to increase the length of the link. In Fig. 4 (not shown), the slide (120) is formed as a housing, and identical one-way acting straps (114), (118), having holes (114a), (118a) through which tie (112) and guide (117) pass, are provided in the housings (110), (120). In Fig. 5 (not shown), the housings (210), (220), are provided with one-way jamming rollers (214), (218). In Figs. 2, 6 (not shown), the ratchets of the adjustable link (176) are of the jamming roller type, and the link is held under tension while the clutch is engaged, so that a decrease in length is required to compensate for wear. The " compression " links of Figs. 3-5, and the " tension " link of Fig. 6, may be converted to the opposite type. The linkage system of Fig. 1 is installed by placing the link 76 in the system and connecting the load spring 54, clutch pedal spring 60, and adjuster spring 51 to their respective elements. The free-play in the clutch pedal is set by manual means 75. The spring 19 is removed from teeth 18 and the slide 20 moved to the left until the flange 20a engages flange 10a. The clutch pedal is then displaced until the clutch is fully released and the screw 24 adjusted to contact flange 20a. The linkage system of Fig. 2 is similarly installed. The slide 20 may carry two flanges and the housing 10 only one. Free-play may be completely eliminated by replacing the lost motion connection 52a by a solid connection, and eliminating the clutch pedal stop and spring 60. Openings such as 14b in housing 10 are provided in all of the housings to facilitate entry of tools to cancel the one-way devices during initial assembly.

Title: Improvements in or relating to cathode ray tubes and signalling systems incorporating such tubes
IPC: H04L21/00
Filed: 1947-07-25
Abstract: 657,053. Automatic control systems for telegraphy. WESTERN ELECTRIC CO., Inc. July 25, 1947, No. 20134. Convention date, Oct. 7, 1942. [Class 38 (iv)] [Also in Groups XL (a) and XL (b)] A high-speed receiver for signals which are of constant frequency but differently phased impulses comprises a cathode-ray tube in which the beam scans, in synchronism with the signal frequency, a circle concentric with a number of targets to one of which the beam is momentarily reflected in accordance with the signal by concentric electrodes. A magnetic or optical record on wire or tape is used for modulating the carrier frequency. The receiver is shown in Fig. 3, and comprises a cathode-ray tube 300 provided with an electron gun 312, a magnetic focusing coil 313, a fluorescent screen 370 and a screen 340 on which are cut 32 stencil characters. The signals are fed to the detector 212 through the receiver 211 and the electron beam scans a circle which is concentric with, and is inside or outside the circle of stencils. The scanning plates 321, 322, the potentials on which are controlled in accordance with the carrier frequency, are connected through the sweep circuit 225, switch 224, amplifier 223, subharmonic generator 222, filter 221 to the detector D. Generators 90, Fig. 2, 228, Fig. 3, which are independent of the signalling frequency, may be used to control in synchronism both the speed of the transmitting film and the scanning plates 321, 322, Fig. 3, through switch 224, Fig. 3. The signalling impulses are supplied over lines 214 to the deflecting electrodes 330, 331 so that the beam is deflected radially across the appropriate stencil to reproduce the selected cipher on the screen 370. A further pair of radial deflecting plates causes the beam to strike the middle of the screen where the letters may read in succession or focused on to a moving photorecording tape (Fig. 3A, not shown). For printing in page form, deflecting plates 360 inside or outside the tube cause the characters to appear in a line on the screen. Each stencil 343, Fig. 6, is surrounded by a disc electrode 344 and associated with segmental electrodes 345, 346. In order to synchronize the receiver with the transmitter, the phase of the scanning beam with respect to the carrier frequency is adjusted by the knob 241, Fig. 3, on the starting circuit until the selected letter appears on the screen. The shaft of the knob may be fitted with an electromagnetic clutch so that when the beam impinges on the disc 344 surrounding the selected letter, an impulse through the line 347 to the starting circuit energizes the clutch to disconnect the knob. Finer adjustment is obtained by the electrodes 345, 346 one of which is hit by the deflected beam if the point of deflection is out of phase so that a correcting impulse is conveyed to the. synchronizing circuit 250. In a modification a synchronizing impulse may be recorded on the transmitter film and a corresponding target 236, Fig. 3, will replace electrodes 344, 345, 346, Fig. 6.

Title: Instrument for measuring distances
IPC: G01C3/18
Filed: 1920-07-09
Abstract: 148,306. Faget, J. M. Oct. 30, 1916, [Convention date]. Range-finders.-Two telescopes L, L<1> are mounted on a graduated slide R, one being fixed and the other movable along the slide by means of a. screwed spindle v rotated from the graduated disk f. The fixed telescope L is mounted to rotate in a vertical plane at right-angles to the slide and is situated above the level of the telescope L<1>, so that the latter may slide beneath the former to the zero mark on the scale, which corresponds with the axis of the fixed telescope. The movable telescope is fixed on its slide at such an angle that, when placed over the unit mark on the scale, the telescope is sighted on an object at a given unit distance. To determine the range of any desired object, the fixed telescope is levelled and sighted on the object, and the movable telescope moved along the slide until the object is again sighted. The range may then be determined from the readings on the slide and graduated disk f. The apparatus is mounted to rotate on a graduated plate supported on a stand.

Filed: 1955-07-14
Abstract: 776,415. Gravity-separation apparatus. SHELL RESEARCH, Ltd. July 14, 1955, No. 20415/55. Class 46. [Also in Groups XVIII and XXXVI] In a plant in which liquid circulating in a conduit 2 is liable to contamination by another liquid immiscible therewith, a collection space 3 is provided, above or below the conduit according to the relative densities of the liquids, and opens into the conduit by an aperture covering at least a substantial portion of the width of the latter. Electrodes 5 . . 8 terminating at different heights are provided in the collecting space and controlling and indicating effects are produced by the change of resistance between one of the electrodes and each of the others as the interface between the liquids reaches or leaves the latter electrodes. As shown, cooling water for an oil refinery flows in conduit 2 and electrodes 5.. 8 are connected to the correspondingly numbered points P5 .. P8, Fig. 2. When contaminating oil forces the water below electrode 7, tube 23 conducts and its anoderelay M disconnects electrode 7 and causes valve 15 to be opened to allow the oil to be expelled. When the water level again reaches electrode 8, tube 23 is disabled, M falls and the valve 15 is closed. If in spite of the opening of valve 15 the water level continues to fall, the uncovering of electrode 6 allows tube- 24 to conduct, and anode relay N operates a special alarm 43. An indicator 42 shows when the valve 15 is open and indicators 41, 40 register the number of times and the total time that it has been opened. The sensitivity of the alarm arrangement can be adjusted by a manually operated throttle valve 16. Gas collected in the collection chamber escapes via path 19, 18.
