Title: Improvements relating to signalling and control systems, primarily for coal face conveyor apparatus
IPC: E21F17/18
Filed: 1954-07-03
Abstract: 759,100. Audible signalling apparatus. DAVIS & SON (DERBY), Ltd., J., and DAVIS, W. B. July 1, 1955 [July 3, 1954], No. 19538/54 Addition to 737,792. Class 118(2) The parent Specification describes a signalling and control apparatus for a coalface conveyer in which a pull wire is attached to a lever, the lever operating the striker of a bell or gong and an electrical switch mechanism when the wire is pulled. The lever is approximately vertical and pivoted at its mid-point and carries guides at each of its extreme ends, the pull wire being led over one or the other according to the direction in which it is to extend. To avoid the difference in pull-wire height due to the wire being round the upper or lower guide the present invention discloses an arrangement whereby only the upper end of the lever 12 (pivoted at 12a) carries a wire guide 13 for use with a pull-wire 15 running in the direction indicated. When it is desired to exercise control from the opposite direction (as indicated by wire 15a) the pull-wire is led over guide 13a at the upper end of arm 6 which is pivoted at 7 and coupled at its lower end to a point on lever 12 a little above the pivot by an approximately horizontal link 5. The amount of movement of the lever mechanism is limited by stops 8 on the frame 10 and the bell and switch actuating arrangements are the same as in the parent Specification.

Title: Pulse noise suppressing circuit in fm stereo receiver
IPC: H04B1/10
Filed: 1977-05-11
Abstract: 1530052 Pulse noise suppression PIONEER ELECTRONIC CORP 11 May 1977 [14 May 1976] 19706/77 Heading H4L  In an f.m. stereo receiver there is provided a pulse noise suppression circuit of the type in which a switch Q 1  in series with the stereo composite signal is opened for a prescribed interval when incoming noise is detected, a stored signal being used as the signal during the interval, the storage arrangement comprising the series arrangement C, R, the component values being so chosen that the cut-off frequency of the circuit 1 as a low pass filter lies below the 19 kHz pilot tone, e.g. at 15 kHz. Effectively this ensures that capacitor C stores only the stereo sum signal, although the whole composite signal is passed to the stereo decoder when switch Q 1  is closed. When switch Q, opens, only the stored, sum signal is passed onwards. Thus, when the composite signal is subsequently low pass filtered to form the sum component, no noise is superimposed on the latter, see Figs. 8a, 8b (not shown). This is contrasted with disadvantageous known arrangements, in which what is stored and passed on is the instantaneous value of the composite signal, resulting in the presence, in the low pass filtered sum signal of a noise component, see Figs. 4a, 4b (not shown). The circuit 1 may include a series inductance, Fig. 9 (not shown).

Filed: 1920-07-08
Abstract: 147,725. Lang, J. Jan. 3, 1919, [Convention date]. Brush stocks; brush-making machines; bristles, fxing.-For securing bristles or fibres in brush heads, metal sleeves with corrugated edges are employed in conjunction with a device comprising a matrix with clamping-grippers adapted to close automatically around the outer sleeve by a single application of pressure from a die. Fig. 1 shows the outer sleeve blank with corrugations a and lateral closing-members b. The edges of the sleeves are rounded off and corrugated longitudinally so that the bristles alternately extend inwardly and outwardly. The device for securing bristles or fibres is shown in Fig. 2, the pressure from the die n causing the grippers f to close around the outer sleeve h and compress the parts of the brush into one compact unit. Simultaneously the lateral closing-members of the outer sleeve are pressed into position and secured by staples stamped out thereon which are bent over.

Title: Electrolysis of solutions and apparatus therefor
IPC: C25B15/08
Filed: 1921-07-22
Abstract: 167,469. Hooker Electrochemical Co., (Assignees of Hooker, A. H.). Aug. 5, 1920, [Convention date]. Alkalies, obtaining; electrolytes, agitating, circulating, and regenerating.- Solid salt is added to the salt solution supplied to an electrolytic cell in order to compensate for the dilution occurring within the cell and keep the electrolyte approximately saturated. In the apparatus shown, brine passes from a tank 2 to a tank 4 bv a valve 7 and a device 8 comprising a rotary member of the Roots' blower type geared by wheels 10, 12 and a chain 11 to a double - flight worm conveyer 13. Solid salt is fed by the worm from a hopper 3 into a pipe 14 whence it is carried by the brine into the tank 4 through a screen 15. The mixture is stirred by agitators 20 operated by a motor 18 and pumped to a delivery pipe 21 by a centrifugal pump 17 operated by the same motor. The delivery pipe 21 is provided with T-pieces into which glass tubes 27 are inserted through rubber stoppers. The tubes 27 are connected by glass tubes 30 and rubber hose 31 to earthenware pipes 32 extending into the cells 5 well below the liquid level. The end of the pipe 21 passes through the bottom of a tank 6 and terminates in an elbow 22, separated by a screen 26 from an overflow pipe 23 by which liquid may return to the tank 4. The pressure in the pipe 21 may be varied by using overflow pipes 23 of different lengths. A modified form of connection to the cells, Fig. 5, comprises a succession of tapered nozzles 34 each smaller than the preceding one and screwed upon it, and an adjustable curved inlet 35 extending into the pipe 21. The curved inlet 35 may be dispensed with. The pipe 21 is inclined so as to equalize the head on the several orifices. The pressure-regulating tank 6 may be dispensed with; in this case the percolation through the diaphragm varies according to the height of the electrolyte in the anode chamber. The feed-regulator 8 may be driven by the stream of brine or by power. The proportion of solid to solution may be adjusted by a proper choice of the wheels 10, 12. The salt in the hopper 3 may be produced by evaporation of the caustic liquor.

Filed: 1949-07-28
Abstract: 676,019. Valves. SAUNDERS VALVE CO., Ltd. July 12, 1950 [July 28, 1949 ; April 18, 1950], Nos. 19874/49 and 9483/50. Class 135. Quick-release mechanism for attaching a valve bonnet to a valve body comprises a number of hook members pivotally connected to one of the parts, say the valve bonnet 1 and adapted to engage the other part, i.e. the valve body 11 and means such as the screwed sleeve 3 for tightening and loosening all the hook members simultaneously when engaged. In the diaphragm valve, Fig. 2, the bonnet 1 has a threaded neck 2 which receives the screwed sleeve 3. The latter has a flange 4 which supports a loose collar 5 having opposed downwardly projecting arms 6. U-shaped members 7 are pivotally supported at the ends of the arms 6. The limbs of the U-shaped members 7 have inwardly projecting hook ends 10 adapted to engage the underside of the body flange 12. The sleeve 3 may be operated by a separate turning device to raise the U-shaped members 7, but as shown has pairs of opposed rectangular notches 13 adapted to be engaged by detachable keys 15 formed by the ends of a stirrup member 16 passing through holes 17 in the handwheel 14. The keys may be permanently secured to or integral with the handwheel, in which case, they normally project upwards and are rendered operative by detaching and reversing the handwheel. The hook members may alternatively be pivoted to the body 11 and engage lugs or pins on the arms 6. The sleeve 3 may alternatively screw on to a projection under the valve body. In Fig. 4 the valve body has four equi-spaced lugs 21. Pairs of triangular toggle plates 23 are pivoted at their upper apices to the lugs 21 by means of rods 24 running parallel to the valve bore. The middle apices of the plates are pivoted at 25 to hook members 26 adapted to engage slight depressions in the top of the bonnet flange 27. The lower apices of the plates are pivoted to trunnion bars having enlargements 29, 30 which can be drawn together by a shouldered bolt 31 with a square or hexagonal head 32 having a hole 33 for a tommy bar. The bolt 31 passes across the space below the weir of the diaphragm valve. The hook members may alternatively be pivoted on the bonnet and engage the pivots 25. Locating pegs 34 engaging recesses in the valve body may be formed on the bonnet flange 35, Fig. 2, or on opposite sides of a finger plate 37, Fig. 4, supporting the diaphragm in the open position.

Title: Improvements in or relating to fluid-pressure servomotor control systems
IPC: F15B17/00
Filed: 1944-10-16
Abstract: 590,699. Fluid-pressure brakes. BENDIX AVIATION CORPORATION. Oct. 16, 1944, No. 19926. Convention date, Dec. 29, 1943. [Class 103 (i)] [Also in Group XXIX] A fluid-pressure servomotor for controlling the wheel brakes of an automotive vehicle comprises a pressure differential member of the vacuum suspended type with a wholly rigid and bodily movable piston and housing a follow-up valve and a lever or linkage mechanism interconnected between the motor, the controlled member, and the operator's control lever whereby "feel" is imparted to the operator. In an embodiment, the control lever 62, Fig. 3, is pivoted to a link 32 connected to a rod 40 on which a piston valve 42 is formed, the valve controlling ports 44 in a tube 22 secured to the servo-piston 14. In the released (dotted) position of the lever 62, valve 42 is urged to the left of ports 44 by its loading spring 46 and both sides of the servo-piston will be in communication and subject to vacuum because of the connection 58 to the intake manifold of the engine. When the control lever is depressed to the full-line position, valve 42 will be moved to the right of ports 44 so that the left-hand end of the servo-cylinder is in communication with atmosphere through ports 44, tube 22, and ports 66. The servo-piston will thus be moved to the right until ports 44 are lapped by the valve 42, and this movement of the servopiston will be communicated to the brakes through an L-shaped member 24 fast on tube 22, a link 28 and a further link 30. As link 28 is also pivoted to the control lever, a proportion of the force exerted by the servo-piston will be communicated to the operator. Should the servo-piston fail to act, continued movement of the lever 62 will cause a pin 34 carried by the link 32 to abut against the end of a slot 36 in the member 24 and the brakes will be applied manually. In a further embodiment, the control pedal 86, Fig. 4, is connected directly to the valve 88, and the servo-piston carries brackets 100 to which are pivoted levers 96 whose free ends bear on the end of the valve spindle. The intermediate parts of levers 96 press on a U- shaped member 104 through which the movement of the servo-piston is communicated to a piston 108 of a hydraulic link leading through a pipe 118 to the brakes. A reservoir is connected to the hydraulic link at 114.

Title: Improvements in or relating to a.c. polarographs
Inventor: BARKER GEOFFREY CECIL
IPC: G01N27/48
Filed: 1957-06-26
Abstract: 870,451. Electric tests. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 3, 1958 [June 26, 1957], No. 20121/57. Class 37. An A.C. polarograph comprises means for amplitude or frequency modulating the A.C. component of the cell current, and means for measuring currents resulting from the demodulation of the A.C. component by the non- linearity of resistive components of the cell impedance due to electrode reaction. Fig. 3 shows the equivalent circuit for a polarographic cell when the potential of the dropping mercury electrode is close to the half-wave potential for the electrode reaction in question, R1 representing the internal resistance of the cell, and C the instantaneous double-layer capacity of the dropping mercury electrodes; R2 is a resistance connected with the kinetics of the forward and reverse processes of the electrode reaction, while the resistive, non-inductive transmission line TL is connected with the diffusion of reacting species to and from the electrode surface. R2 and TL become non-linear when the A.C. voltage across C is comparatively large, and produce the demodulation of the A.C. component. Fig. 6 depicts a circuit in which the voltage applied to the cell PC comprises a slowly-varying D.C. sweep voltage and a sinusoidally modulated H.F. wave, the modulating wave being separated from the H.F. and slowly varying components by filters, amplified, and passed to a phase-sensitive detector where it is separated from the A.C. component associated with the double layer capacity of the cell. The output of the detector is fed to a pen recorder. When the frequency is in the Mc/s. range, a substantially constant modulated A.C. is applied to the cell, a separate voltage sweep generator being employed to control the mean value of cell voltage, Fig. 7 (not shown). The modulating wave may be of square waveform, in which case the phase-sensitive detector is replaced by a time-sensitive detector.

Title: Improvements in and relating to the testing of insulating material on a conductor
Inventor: TOWNSEND LEONARD WILLIAM ERNES
IPC: G01R31/02
Filed: 1953-07-22
Abstract: 734,557. Cable insulation testing. PERMANOID, Ltd. [formerly ASSOCIATED TECHNICAL MANUFACTURERS, Ltd.]. July 22, 1953, No. 20302/53. Class 37. A method of testing the insulation of cables comprises running the cable through a bath of conducting fluid and applying between the conductor, at earth potential, and the fluid a high rectified R.F. voltage of frequency not less than 10 kc/s. derived from a tuned anode coupled oscillator, supplied with H.T. by an A.C. supply via a full-wave rectifier and capacitive input smoothing circuit. A fault in the insulation results in actuation of a relay which completes the circuit to an audible or visual warning device or to a cable marking device. In Fig. 2 the oscillator is tuned by condenser VC1 and in the absence of a fault the secondary winding L3 of transformer T1 is on open circuit, the standing D.C. anode current being adjusted by the potentiometer VR1 so as not to actuate the relay RL. A fault in the insulation virtually short-circuits winding L3, thereby reducing the feedback to the grid circuit of VI, causing a fall in the automatic bias. The resulting increased anode current operates relay RL, putting the bell B or other warning device in parallel with the filament supply to VI. The cable marker may consist of a relay fitted with a time-delay mechanism which operates 2 pens carrying coloured inks to mark the cable in advance of and at the fault. Operation of one of the push buttons open circuits the cathode and releases the relay. Release of the button before removal of the fault causes immediate re-energizing of the relay. The test voltage required is far less than when low-frequency A.C. is used (circa 3000 v.) but is more efficient in detecting faults.

The web has an outer end 13 of ring form tapped to receive the bolt 18. A second washer 21 permits the end 13 to draw away, slightly, from the panel on tightening the bolt. The hole in the end 13 may be flanged to provide a longer threaded engagement. The hole in the panel may be counterbored, in which case the washer 21 will not be needed. A projection may be embossed in the web to force the bolt against the opposite wall and the web may be formed to engage the bolt threads. In a modification, the bent-up end portion 14, Fig. 7, to engage the inner side of the panel is provided with a hole tapped for the bolt, and in this case the other end 13 is formed with a clearance hole 29. The front end of the hole may be countersunk and the end 13 is then correspondingly shaped. In a further form in which the tapped hole is in the rear end, this end may be separate and slotted to slide along the web, complete removal being prevented by turned-over lugs.
