Title: A sack-loading device for attachment to a tractor
IPC: B66C23/44
Filed: 1959-12-04
Abstract: 913,907. Lifting devices for use on tractors. NORBURY, E. Jan. 31, 1961 [Dec. 4, 1959], No. 41215/59. Class 78 (3). A sack 18, Fig. 1, is lifted from the ground and placed on a trailer 45 by a power-operated arm 11, 12 which has gripping jaws 16 and swings upwardly and outwardly about an inclined pivot within the sleeve 9. The tractor is driven alongside the sack and a flexible wheel runs on to the sack and guides the jaws 16 into gripping position. Manual operation of a quadrant 32 closes the jaws by means of a cable 24, a pawl engaging the quadrant to retain the jaws in closed position. The lift mechanism of the tractor is now operated to move a rack 37, Fig. 5, which engages a quadrant, to the left through members 38, 39 to first swing the arm 11 about a horizontal pivot 7 to lift the sack off the ground, and subsequently to swing it upwardly and outwardly about the pin 10. The weight of the sack causes the member 12, Fig. 1, to swing downwardly, thus tightening the cable 24 and increasing the grip of the jaws 16. When the sack is over the trailer a release chain 31, Fig. 5, becomes taut and by disengaging the pawl 30 from the quadrant 28 allows the sack to drop. A rebound spring 41 urges the arm back to its original position. Finally a pawl 44 is released to permit the arm to swing downwards about the pivot 7 until an adjustable stop 40 abuts a detachable mounting tube 1. The tube 1 may be used to carry the bale-stacker described in Specification 766,911.

Abstract: 892,933. Burners. LUCAS (INDUSTRIES) Ltd., JOSEPH. Nov. 7, 1960 [Dec. 7, 1959], No. 41436/59. Addition to 852,418. Class 75(1) A burner removably mounted on a furnace front 28 comprises two separable body. parts 5, 6 clamped together by a pivoted yoke 15 and a screw 16, a hollow spigot 18 in the part 6 engaging with a socket in the other part 5 to convey fuel from the part 6 to a burner 9 on the end of a pipe 8 removably mounted in the part 5 and a plug valve 20 mounted in the part 6 and having a dog 27 which engages in a groove in a rotatable spindle 26 in a bracket 24 secured to the furnace front, the dog 27 serving to prevent axial movement of the burner from the furnace front whilst the plug valve is open. When the plug valve is in closed position the dog 27 can be slid out of the groove in the spindle 26 and out of an upper part of a slot 24a in the bracket 24, thus allowing the burner to be removed from the furnace front. A hood 30 on the furnace front then no longer prevents access to the handle 31 of the clamping screw 16 and the stem 22 of a spring closed valve 19 in the part 6 is withdrawn from abutment with a part 23 of the bracket 24 allowing the valve 19 to close. The spindle 26 is rotated to operate the plug valve 20 by a handle 25 extending through a lower portion of the slot 24a in the bracket 24. The burner pipe 8 extends from a head 7 slidable in the body part 5 and held therein by the screw 16. A projection 13 on the head 7 extends into a groove in the body part 5 and is located between the body part 5 and a stop 14 on the body part 6. In a modified construction the spring closed valve 19 is omitted.

Abstract: 1334718 Recovering rubber UNION CAR BIDE CORP 13 Sept 1971 [14 Sept 1970] 42518/71 Heading C3E Rubber is recovered from fabric or fibrereinforced rubber articles by cooling the articles, or subdivided pieces thereof, with a cryogenic material to a temperature sufficiently below - 40 C. to embrittle the rubber component, disuniting the rubber component from the fibrous component by flexing, crushing or comminution and removing at least part of the fibrous component by mechanical or cyclonic separation. The separation step may involve screening of the disunited material and, when metal is to be removed, passage through a magnetic separator. The rubber chunks obtained may be further comminuted in, e.g., a ball or hammer mill or a fluid energy device, cooled by coolant recovered from the embrittlement stage, to yield particles which are then screened and classified, using a dispersant such as carbon black or silica, if desired. The entire process may be carried out under cryogenic conditions. The particles produced may be devulcanized.

Abstract: 1408385 Testing engines LESLIE HARTRIDGE Ltd 8 Sept 1972 [15 Sept 1971] 43050/71 Heading G1N The performance of an I.C. engine 10, Fig. 1, is checked by transducers which measure the parameters of the engine and feed corresponding signals to a processing cabinet 46 wherein the speed, power, timing, &c. are calculated, indicated on meters and recorded on a report card 66. Speed and acceleration are measured by equispaced pairs of marks 34 as the engine flywheel 22, defining the top dead centre of each cylinder piston and separated by a known angle, the marks producing pulses in a transducer 36, 38. The time interval between the pulses of each pair is measured in the processor 46 and used to determine the power of each cylinder. One mark and two transducers may alternatively be used. The timing of the injection of fuel into a cylinder is determined by a transducer 44 sensitive to pressure in a feed pipe 16, which is timed relative to the instant corresponding to top dead centre, obtained from the marks 34 on the flywheel 22. The transducer 44 may be associated with each cylinder in turn. The engine exhaust gases are tested by a photo-electric smoke meter 48. The test procedure is controlled manually or is based on a program recorded on a card 60, the first step being to measure the peak values of the current taken by the starter motor 26, being a measure of the compression in each cylinder.

Title: Improvements in transistor logic circuitry for digital systems
Inventor: REES FREDERICK HENRY
IPC: H03K5/14
Filed: 1961-12-07
Abstract: 966,600. Transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. Dec. 30, 1962 [Dec. 7, 1961], No. 43899/61. Heading H3T. In a transistor logic circuit, biasing pulses a+ (Fig. 8) are applied to the base in the cut-off direction together with any signal pulse (e.g. from A, B or C) that may be present, the signal pulse when present exceeding the biasing pulse so that a charge is stored in the base, and interrogating pulses b are subsequently applied to the collector before the next bias pulses so that an output pulse appears at the collector only if the transistor is non-conducting, i.e. if no signal pulse accompanied the bias pulse. The circuit may be followed by an emitter follower buffer stage (Fig. 2, not shown) comprising clamping diodes to improve the waveshape and may be preceded by an inhibit gate in which the base receives bias and inhibit signal pulses simultaneously with signal pulses applied to the collector so that the inhibit gate produces an output only in the absence of an inhibit pulse. Residual charge stored in the base may be removed by intermediate pulses between the bias pulses (Fig. 5, not shown). Stages may be coupled through two silicon diodes (Fig. 7, not shown), the forward voltage of which ensures that successive transistors bottom. One diode may, however, be replaced by a resistor or, where A.C. coupling is required, by a capacitor. A logic " ONE " may be represented by a pulse in phase A and by the absence of a pulse in phase B so that if line D imposes a delay equal to that between phases logic inversion is produced in the line. Accordingly, the circuit of Fig. 8 performs the logic function (A + B + C) or (A.B.C), depending on the mode of operation. The line may be terminated at both ends by matching resistors (Fig. 9, not shown) and diodes may be provided to prevent reflections. Fan-wise connection is facilitated by providing an input delay line which introduces only a short delay (Fig. 10, not shown). Stages may be arranged in cascade with or without the lines to increase the delay and may then be formed into a loop to provide a recirculating pulse store (Figs. 4, 12 and 13, not shown). Erasure of stored pulses may be effected by inserting an over-riding pulse of the same phase position but of opposite polarity or of the same polarity in another phase position. Single phase (Fig. 11, not shown) and 3 phase operation are also possible.
