Overload is sensed by a device 39. The anvil may alternatively have a translational rather than pivotal motion. The apparatus is started e.g. by the entry of garbage actuating a photo-cell/light beam control device or a flap switch 47. The teeth on the drum are arranged in diametrically-opposed pairs, and comprise steel blocks welded to the drum, or drum and teeth may be an integral casting or be composed of a stack of laminae. The anvil elements 83 comprise triangular plates and cooperate with an hydraulic ram 95 which is set by a relief valve 101 Fig. 14 to yield at a predetermined pressure. Water may be used to dampen garbage entering the machine, e.g. via a chute 5, and deodorising chemical may be added via an injector 106. The stripper plates include abrasive strips 175 Fig. 12, and similar strips 56 Fig. 6 are provided on end plates 54 of the drum 11  serve to grind down any entrained and stubborn material e.g. stockings, string &c. An electrical controller 41 is programmed to initiate an unjamming sequence if the drive motor becomes overloaded. Normally, however, the drum runs at 40-50 feet per minute peripheral tooth speed. Waste from the apparatus may be compacted into blocks e.g. impregnated with concrete, resin or bitumen. In a further system soft material is reduced to a slurry and the heavy and metal objects are delivered to a bag-packaging apparatus (163) Fig. 20 not shown.

Title: Apparatus for recording and reproducing quadraphonic sound
IPC: H04H20/88
Filed: 1972-02-23
Abstract: 1387874 Quadraphonic systems CBS Inc 23 Feb 1972 [15 March 1971] 8412/72 Heading H4R In a quadraphonic system in which the four signals L f , R f , L b , R b  are matrixed on to two transmission channels each channel carries a respective predominant signal R f  or L f  together with sub-dominent signals R b  and L b . The signals are combined after phase shifting such that, in each channel, the two sub-dominant signals receive a phase shift differing one from the other by 90 degrees, with the signal R b  receiving the greater phase shift in one channel and the signal L b  the greater phase shift in the other. The signals R f  and L f  in each channel receive the same phase shift, and the same phase shift as, respectively, the subdominant component L b  or R b  in its own channel. Alternatively the phase shift may be such that the subdominent components in one channel are in antiphase with the positions referred to above. Fig. 7 shows a preferred embodiment of one encoding matrix and Fig. 5 (not shown) a second similar matrix. The alternative arrangement, Fig. 8, having the subdominant components in one channel in antiphase to those shown in Fig. 7, is said to give better discrimination between centre front and centre back signals than the arrangement of Fig. 7. The decoder used can be the same as that of Specification 1,387,873 but an alternative form, Fig. 12, is more suitable for the coding system of Fig. 8. The major portion of the arrangement of Fig. 12 is equivalent to that of Figs. 4a and 4b of Specification 1,387,873, with appropriate phase change in combiner 326, but an additional logic circuit is provided, 354 to 378, which compares the sum of the two channel signals with the difference of the two channel signals, which is shown to discriminate a centre front signal from a centre rear signal, and the result of this comparison is combined with the output of the conventional logic circuit 340 to operate the controlled gain amplifiers 312, 314, 322, 328. The outputs of the two circuits can be added, as shown in Fig. 12, or the maximum signals picked off as described with respect to Fig. 12A (not shown).

Title: Selective signalling arrangement for radio channels
Inventor: KING JOHN ARTHUR BARFIELD
IPC: H04M11/00
Filed: 1956-03-20
Abstract: 809,232. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. March 20, 1956, No. 8601/56. Class 40 (4). [Also in Group XL (c)] In a relay circuit for coupling a telephone line to a radio transmitter, the seizing or looping of the line connects it to the audiochannel of the transmitter, but the front of the first dialling impulse breaks this connection until the dialling impulses being repeated to the transmitter over another channel. In the embodiment shown when a two-wire line A, B is looped line-relay LS operates and Ls1 operates a slugged relay B, completing a circuit through cd1 for high-speed relay SC in the anode circuit of VI, thus completing the speech path through contacts SC1 and SC2. Relay contact ls2 prepares the transmitter circuit connected at XYZ for the retransmission of selecting signals by changing of contacts ls2. When the dial springs open for the first time the surge voltage imposed on the line and induced in winding T of transformer TR, is rectified by MR1 producing a negative bias voltage on the control-grid of VI, and reducing the anode current of VI so that relay SC releases and disconnects the speech path between the access path A, B and the audio channel at SC1 and SC2. Slightly later LS releases and at ls1 operates relay CD through contact bl of relay B. When relay LS reoperates at the end of the first dial break period relay SC cannot operate because contact cd1 is open. At the end of the last dial break period relay CD eventually falls off and relay SC re-operates, reconnecting the through-audio channel.

Title: Drive mechanism for the flint wheel of a pyrophoric lighter
IPC: F23Q2/46
Filed: 1970-02-23
Abstract: 1300245 Pyrophoric lighters S T DUPONT 23 Feb 1970 [21 Feb 1969] 8670/70 Heading F4F [Also in Division F2] A drive mechanism for imparting rotary move - ment to a flint engaging wheel of a pyrophoric lighter comprises a control member 1, in the form of a rotatable disc coaxial with the body of the lighter, which engages via a resilient means (a helicoidal spring 11) a pivotable operating lever 7, a rotatable member in the form of a ratchet wheel 17, intended to rotate with the flint wheel, and a support member in the form of a rocker 21 adapted to prevent the operating lever 7 from pivoting on initial rotation of the control member 1, potential energy being stored in the spring 11 during this initial rotation, such that, on further rotation of the control member 1, the rocker 21 allows the operating lever to pivot under the action of the spring 11 whereby a connecting means in the form of a small rod 12 and a detent 18 engages the ratchet wheel 17  and thus rotates the flint wheel. Figs. 1, 2, 3 show the mechanism in rest, operating and release positions respectively. The control member 1 is rotatable about an axle 2, which is attached to a fixed circular plate 3 having a large notch C. In the rest position the rocker 21 is in contact with a stop 23, and the short arm of the rocker, which bears a roller 25, is in contact with a cam section H on the operating lever 7, so that the lever 7 is kept immobile by the roller 25 and by a slight pressure of the spring 11. When the control member 1 is rotated, a piece 4, integral with the control member, moves along the notch C, (Fig. 2), and so the spring 11, which is pivoted by means of a rod 10 to both the piece 4 and the lever 7, is compressed. On further movement of the piece 4, the rocker 21 is suddenly released, since a roller 26 on the long arm of the rocker escapes projection A on the piece 4, and the roller 25 from the cam section H (Fig. 3). As the lever 7 is no longer held immobile it pivots about its axle 8 by the action of the spring 11 so that a small plate 15, which is connected by a small rod 12 to the lever 7, is rotated about an axle 16, which is also the axle of rotation of the flint wheel. The ratchet wheel 17, which is integral in rotation with the flint wheel axle, is driven by a detent 18 on movement of the plate 15, the detent being applied to the ratchet wheel by means of a further spring 20. The pivoting of the lever 7 is restricted by a stop 27, and on release of the control member 1 the mechanism is returned to its rest position by means of springs 28 and 24.

Filed: 1968-02-23
Abstract: 1,216,761. Sheet glass manufacture. PERMAGLASS Inc. 23 Feb., 1968 [15 March, 1967], No. 8899/68. Heading C1M. Molten glass 14 is fed from a melting tank into a drawing chamber 36 where it is entrained in the nip of a pair of continuously rotating rolls 16 which convey the glass upwardly to form an elongate-body. 20.of onion shaped crosssection-.and a sheet 24 is simultaneously drawn out of the body 20. Preferably whilst the sheet is still deformable it is bent into the horizontal position on to a gaseous support bed 30 over which it is conveyed before engaging the drawing rolls 26. The rolls 16 are formed of graphite boron nitride or disilicide molybdenum, and to prevent their oxidation an inert or reducing, e.g. carbon dioxide atmosphere is maintained in chamber 36. A suitable system of gearing drives the rolls 26 in synchronism with rolls 16. The glass in the melting chamber is maintained above the liquidus temperature, and in the body 20 below liquidus but at such a temperature as to fire polish the glass. To achieve thisfor <SP>1</SP>/ 4  inch sheet the glass should remain in the body 20 for from 10 to 100 seconds. The support gases of bed 30 are burned hydrocarbon gases at graduated temperatures to provide the desired degree of cooling of the sheet 24 for when it contacts rolls 26. To prevent molten glass entraining in the gear mechanism the geared ends of the rolls 16 are surrounded by caps 44, although if desired the rolls 16 may have small diameter end portions connected to gear-wheels located in sealed enclosures. The rolls 16 should never become wholly immersed in the molten glass and this necessitates careful control of glass level. A cooling fluid is passed through rolls 16. However in an alternative embodiment (see Figs. 6 and 7) the rolls 16 float in the molten glass bath, the drive mechanism being suitably pivoted so that it is always held in contact with the rolls 16. The drive mechanism is so regulated that molten glass is fed to the body 20 at the same rate as it is drawn out on to sheet 24.
