Title: Improvements in or relating to tool carrying chains for use on mining cutters for coal and like minerals
IPC: E21C25/36
Filed: 1952-04-21
Abstract: 737,880. Chains. PROCTOR, S. E., and HOY & CO., Ltd., A. June 30, 1953 [April 21, 1952; July 4, 1952], Nos. 10033/52 and 16912/52. Class 24. A coal cutter chain of the type in which the joints between the links are ball-and-socket joints comprises means for adjusting the pitch of the chain by altering the spacing between the ball members thereof. In the chain shown, which is of the type described in Specification 626,080, the ball 18 of each ball-and-socket joint is eccentrically mounted on a shaft 17 adjustably supported in a chain link 11 so that rotation of the shaft with respect to the link results in variation of the pitch of the chain. The shaft 17 is locked in position by a pin 20 engaging one of a number of slots 19 cut in the face of the link block 15. Alternatively, the square 21 on the top of the stem 17 may be made longer and the upper portion of the bore in the block 15 constructed with a cross-section in the form of an eightpointed star. The square 21 engages the points of the star which provides positions of adjustment at angles of 45 degrees to one another. As further alternatives, the eccentric stem 17 may be located eccentrically in a surrounding bush of square cross-section mounted adjustably in the block 15, or the ball 18 may be made concentric with its stem 17 which passes at an angle through a bush mounted in the block 15, or a liner may be provided which is bored out so that the socket portion in the interior is eccentric to the exterior and the pitch can be adjusted by rotating the liner in its bore or by replacing the liner with another liner of different eccentricity. In the type of chain described in Specifications 699,636 or 715,776, in which the ball-stem extends from the socket directly towards the neighbouring link, the ball is made adjustable relative to the stem by means of a screwed joint.

Filed: 1916-07-19
Abstract: 101,338. Algrin, R., and Breton, J. L. Aug. 28, 1915, [Convention date]. Valves; valve-gear.-Compressed air is admitted io the cylinder past two beat-valves, one of which also controls the admission of liquid fuel. The two valves may be arranged side by side, or, as shown, coaxially. The valve 2 opens first, admitting air only, then by a further movement it opens the valve 3, which uncovers the nozzle 14 from which fuel under pressure flows; the valves may close simultaneously or the valve 2 may close last. The valves are applicable to both two-stroke and four-stroke-cycle engines. In the former, the valve 2 opens at the same time as the terminal exhaust ports, and, just as these are about to be closed, the valve 3 opens; both valves close at about half in-stroke. In a four-stroke-cycle engine the exhaust valve remains open during the beginning of the charging out-stroke when the valve 2 is also open, the valve 3 then opens and closes just before the end of the stroke, and afterwards the valve 2 closes.

In a coaxial line oscillator tube of the electron velocity modulation type the outer conductor 1 of the internal coaxial line section is connected to a disc 2 sealed through the glass envelope 3, the disc 2 being clamped to the outer conductor 4 of an external coaxial line. The conductor 1 is apertured to provide a passage for an electron beam from an electron gun 5 to a collector electrode 6 and the centre conductor of the internal line is apertured and comprises a conductor 7 having a pair of fins 8 which define a drift space for the electron beam. The conductor 7 is secured at its upper end to a metal cup 9 which is secured to an annular disc 10 of insulating material supported on a ledge 11 formed on the inside of the outer conductor 1. At its lower end the conductor 1 is closed by a section of wave-guide 12 whose cut-off frequency is much higher than the highest frequency generated by the oscillator. The cup 9 is secured to members 7 and 8 by welding, a metal ring 13 being added and the whole silver-soldered. During assembly the drift space between the fins 8 and the apertures in conductor 1 are held in correct alignment by a mandrel and the disc 10 is placed over the cup 9 and the top edges of the cup spun over, the edge of conductor 1 also being spun over the disc 10 to form a rigid structure. Alternatively the disc 10 may be coated with metal on the inner and outer edges and the members attached by silver-soldering. An output conductor 16 is secured in the cup 9 by means of a tin joint formed during final processing, and passes through the glass envelope to fit into the internal conductor 17 of the external line, the complete resonator being tuned by a piston 18. In cases where the internal coaxial line is a quarter or threequarters wavelength long the disc 10 may be coated with metallic material on one surface to form either an inductive or capacitative diaphragm.

Abstract: 1,187,551. Cams; chain gearing. POWERS MFG. Inc. 4 March, 1968, No. 10401/68. Headings F2K and F2Q. [Also in Division G1] A cam 24 rotated by a motor 31 via a shaft 29 is engaged by a follower 25 secured to a carriage 16 biased by springs 26, 27. The carriage is mounted on rollers 17, 18 and the periphery of one half of the cam is formed such that equal incremental angular rotations of the cam cause equal incremental horizontal displacements of the carriage. The other half of the cam periphery has a sinusoidal form to allow a smooth return of the carriage. The movement of the carriage is synchronized with the movement of bottles 11 to enable a gauge 13 to test the necks of the bottles whilst the bottles are moving. To achieve this synchronized movement, the bottles are advanced by a screw conveyer 54 driven by a shaft 56 which is rotated by the motor 31 via a chain 58 and a sprocket 57. The timing of the screw conveyer with respect to the cam 24 is obtained by an idler sprocket 61 mounted on a swinging arm 62, the position of which is adjustable by a manually rotatable telescopic link device 63. A sprocket 65 mounted on a swinging arm 66 biased by a spring 67 maintains the tension in the chain throughout the range of adjustment of the sprocket 61.

Title: Improvements in and connected with multi-picture cameras
IPC: G03B19/02
Filed: 1927-04-19
Abstract: 294,159. Doogood, L. J., and Branagan, L. P. April 19, 1927. Cameras for taking a series of photographs on one plate. - The lens is moved in steps across the plate, then stepped down and returned across the plate, and so on, each movement of the lens being effected by a shutter-operating lever and just after an exposure. The lens 36, Fig. 1, and actuating mechanism are mounted on a plate 8 fitted with rollers 9, Figs. 1 and 2, which slide on a transverse frame 7. This frame 7 slides on a fixed frame 5 and is supported by a spring catch 10 engaging one of a series of pins 6 in staggered relationship on opposite sides of the frame 5. The catches 10 are released alternately by mechanism on the plate 8. The frame 7 has a series of pins 13 between which a movable locking plate 14 engages to position the lens in successive horizontal positions. On actuating the lever 28, the shutter is operated by a pivoted lever 30 which moves the pivoted element 34 connected to the shutter operating member 35. A projection 32 on the lever 30 depresses a link 33 and with it a V-member V : a pawl 24 on this member depresses a stud 21 on an M-shaped member 19, Fig. 3, which is pivoted on the base plate 8. The shaped part 20 of the member 19 depresses a stud 20a on a spring-controlled lever 18<a> : a shaped cam-finger 17 on this lever engages a shoulder 16 on the movable plate 14 moving it down clear of the pins 13 on the frame 7 : also the resilient pawl 22 on the M-plate 19, on the side opposite the stud 21 engaged by the pawl 24, engages a pin 13 and by the rocking movement of the M-plate shifts the base plate 8 to the left : then the cam finger 17 is disengaged by a projection 18 on the plate 8 to release the shoulder 16 on the plate 14 which is returned upwardly by the spring 15 and re-engages between the next pair of pins 13. When the plate 8 arrives at the end of the frame 7 a projection 37 releases the spring catch 10, and the frame 7 drops until the catch 10 on the opposite side engages the next pin 6. The fall of the plate 7 is cushioned by a resilient projection 40 which engages a lower pin 6 before the catch 10 arrests the frame. Also one arm of a rocking lever 25 is engaged by a pin 6, tilting this lever and thereby throwing over a lever 26 to the other side of its dead centre 23, this action also, by means of the spring 27, throwing over the U-shaped plate so that the opposite pawl 24 engages the opposite stud 21 on the M plate 19. Successive operations of the lever 28 will then move the plate 8 in the opposite direction on the frame 7. The base plate 8 is returned to its original starting position after the photographic plate is completely exposed by hand manipulation of the lever 25 and other parts of the mechanism. The part of the photographic plate 44, Fig. 4, not immediately exposed through the lens 36 and barrel 43 is protected by a series of light-excluding sliding plates 45, one of which is directly mounted on the barrel 43.

Title: Flash and camera device
IPC: G03B15/03
Filed: 1977-03-14
Abstract: 1523421 Camera and flash combination WEST ELECTRIC CO Ltd 14 March 1977 [17 March 1976] 10672/77 Heading G2A A camera and electronic flash combination has a switch 11 which is closed upon depression of a shutter release 2 to connect the flash capacitor 23 to its battery 17, and means controlled by a light sensing circuit 13 and operative when the sensed light is low to hold the switch 11 closed until the capacitor 23 is charged. As shown, depressing release 2 causes depression of a member 4 to close switch 11. If the sensed light is low, then light sensing circuit 13 turns on an SCR15 to energize an electromagnet 16. This locks member 4 thereby keeping switch 11 closed and also preventing further movement of release 2. When the capacitor 23 is charged it turns on a tube 29 and a transistor 30. This shorts the electromagnet 16 to allow release 2 to be depressed further and operate the shutter. The flash is fired by closing a synch contact 32. If the sensed brightness is high, movement of release 2 is unhindered. Also in this case, the light sensing circuit 13 via switches 27, 26, 25 prevents the flash firing when contact 32 is closed. In Fig. 2 (not shown), the photo-sensor 14 can be manually switched out to enable flash to be used in daylight conditions.

Filed: 1924-05-02
Abstract: 215,376. Rouiller, V. D. May 2. 1923, [Convention date]. No Patent granted (Sealing fee not paid). Indicators actuated by floats.-The volume of liquid in a petrol tank is indicated by means of a submerged float the pressure on which is transmitted through liquid in a pipe to a Bourdon gauge. The tank 1 is assumed to have a varying cross section, equal increments of volume being represented by the scale 22. The float is constituted by a number of elements 10<a>, 10<b>, 10<c> of equal volume, but having heights corresponding to the divisions on the scale 22. The floats are mounted on a tube 11, having an internal spring which neutralizes their weight. The composite float is guided by projections 17, 14, at the two ends, and is enclosed in a perforated cylinder 3. The upward force on the float due to its immersion is transmitted to a corrugated diaphragm 19, and thence through glycerine in a tube 21, to a Bourdon gauge. The gauge indications are proportional to the volume of liquid in the tank.
