Title: Pressure actuated fuel control for super-charged engines
IPC: F02D1/00
Filed: 1962-07-06
Abstract: 949,558. Regulating I.C. engines. CATERPILLAR TRACTOR CO. July 6, 1962 [Aug. 4, 1961], No. 25975/62. Heading FIB. In an I.C. engine having a movable fuel supply control member 13, Fig. 1 associated with a governor and an engine driven supercharger 23 supplying air to the intake manifold, means responsive to intake manifold pressure for overriding the governor and limiting movement of member 13 under high fuel demand/low speed conditions comprises fluid pressure means 28 biasing member 13 in a fuel-decreasing direction, a valve 38, 39, for bleeding fluid from the biasing means, means operable to close the valve when the intake manifold pressure is low and means operable to impart opening movement to the valve upon movement of the member 13 to decrease fuel supply. The output of each fuel pump 10 is adjusted by movement of member 13 which meshes with gear 14 fixed to pump plunger 11. Engine oil under pressure enters cylinder 26 through line 33, orifice 65 and passages 34 and 35. Under normal operating conditions, inlet manifold pressure is communicated to chamber 52 where it exerts a downward force on flexible diaphragm 44 which is secured to a slidable valve spool 38 thus tending to bleed pressure oil through ports 53, in a slidable valve body 39, through annular groove 54, the axial passage in valve spool 38, recess 56 and slot 57 to drain to the engine sump. Reduced pressure in cylinder 26 then allows piston 28 and member 13 to be moved to the left by springs 15 and 31 thus causing downward movement of valve body 39 by means of engagement of ball end 61 in slot 60 which tends to close communication between ports 53 and annulus 54 until a balance establishes a fuel feed setting corresponding to intake manifold pressure. In another embodiment the connection between rack bar 13<SP>1</SP> Fig. 3 and valve body 39<SP>1</SP> is by a lever 70 which engages pin 72 and projection 73. Specification 783,322 is referred to.

Title: System for comparing binary codes
IPC: G06F7/02
Filed: 1959-07-29
Abstract: 940,184. Magnetic core coincidence gates. E. DAMOND. July 6, 1960 [July 29, 1959], No. 26065/59. Drawings to Specification. Heading H3B. An A.C. coupling over a magnetic core gate is permitted only when a number of control windings are all unenergized or a number of pairs of control windings are energized in opposition. The gate is used to find coincidence between a static set of twelve binary markings and a series of such markings presented in parallel. With each of the static marks applied to one end of a control winding and with the corresponding mark of the series applied to the other end of the winding, coincidence of all twelve marks results in none of the control windings being energized and an A.C. output being developed over the core. Alternatively, the static marks may energize one set of control windings in senses depending on their binary values, while the serially presented marks energize a second set of control windings in reverse senses so that coincidence produces a balance and an A.C. output. Two such gates may be used in parallel with their outputs connected to an AND gate.

Filed: 1961-07-18
Abstract: 985,033. Loom stop motions. RUTI MACHINERY WORKS Ltd. July 18, 1961 [July 18, 1960], No. 26072/61. Heading D1E A warp stop motion, which stops the loom at closed shed through a lever mechanism 8, 7, 9, 10, 39 and 40, has attached to it a second mechanism which stops the loom at open shed on weft failure or on non-arrival of shuttle. A side weft fork lifts a cable 26 to pivot a lever 20 which moves a rod 18 to the right. Movement of the rod 18 allows a spring 16 to pivot a lever 14 so that its lower end 14a comes into the path of a roller 4 adjustably mounted on the sley sword 1. The warp stop motion is not actuated until the return beat (anti-clockwise) of the sley whereupon the roller 4 pulls the lever 14 until it abuts a stop 15, pivots the lever 7 and stops the loom. Non-action of shuttle swells lifts either of cables 27, 28 to raise a leaf spring 22 which allows the spring 16 to move the rod 18, the lever 14 to pivot and causes the loom to stop at the next return beat of the sley. By manually lifting the spring 22 the loom may be operated on single picks. Two other embodiments are described (Figs. 3, 4, 5 and 6, not shown).

Abstract: 1390574 Machine frames MASCHINENFABRIK SACK GmbH 31 May 1973 [13 June 1972] 26083/73 Heading F2X A multiple-part machine frame with a rectangular opening for a press, rolling mill, &c. comprises transverse struts 1, 2 which take up the force of reaction P of the working force and transmit it to longitudinal struts 7, 8 via forcetransmitting surfaces 3, 4, 5 and 6. These surfaces are formed by projections 1a, 2a on the ends of the transverse struts 1, 2 and projections 7a, 8a on the sides of the longitudinal struts 7, 8. The transverse and longitudinal struts are connected by first tie-rods 9, 9a, 10 and 10a extending transversely to the longitudinal struts. In order to prevent the surfaces 3 to 6 from hammering against each other when relieving impacts occur, for example, when the rolled material leaves the rolls or during forging, pre-stressed second tie-rods 11, 12, 13 and 14 interconnect the transverse and longitudinal struts and pass obliquely through the forcetransmitting surfaces which are thus kept permanently in abutment. Destruction of these surfaces by constant hammering is thereby prevented.

Abstract: 318,258. Comptoir des Textiles Artificiels Soc. Anon. Sept. 1, 1928, [Convention date]. Tension arrangements. - In order to stretch a freshlv coagulated artificial thread without excessive sliding friction, the thread is passed around a rotor which is adapted to be rotated by the thread and is provided with means for retarding its speed of rotation. As shown, the thread passes behind a guide 12 around a rotor 14 mounted in the precipitating bath 3, and then in front of the guide 12 to a take-up device. The rotor 14 is fitted through a bore 15 on a shaft in a casing 1, and carries on its rear surface vanes which co-operate with vanes or flanges in the casing to reduce the speed of rotation; the thread is thus subjected to tension between the rotor and the takeup device. The flange 17 forming the rear surface of the rotor may fit loosely into the casing 1 so that the vanes rotate in the precipitating liquid, or the vanes may be caused to rotate in a bath of oil retained in the casing, or in air. The rotor may be arranged at any point between the spinning nozzle and the take.-up device. Two rotors may be used in series, or one rotor may be used in combination with hook or other guides.

IPC: A23B4/052
Filed: 1954-09-14
Abstract: 781,591. Method of producing smoke from sawdust. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Sept. 13, 1955 [Sept. 14, 1954; Feb. 18, 1955], Nos. 26641/54 and 4949/55. Class 81 (1). In a method of producing smoke from sawdust the latter is partially burnt or otherwise decomposed by heat as a fluidized bed. As shown, gas heated to a temperature to decompose the sawdust to produce smoke passes in the direction of the arrow 3 through a gas inlet cone 2 and the venturi throat 4, across which wire gauze 5 is secured, of a fluidization chamber 1 which is maintained about one-third filled with sawdust which has been passed through a 25-mesh British Standard sieve either by batchwise feeding or else by continuous feeding by means of a worm 7. As the sawdust enters the chamber 1 the finest particles are carried by the gas stream directly to a cyclone separator 6 without appreciable charring taking place, the remainder being maintained in a fluidized state by the gas stream whilst it is charred to produce smoke which passes via the separator to a kiln, e.g. fish smoking kiln, and the char is recovered at 8. A proportion of the gas and smoke from the kiln may be recirculated through the fluidization chamber to increase the smoke concentration. Specification 544,229 is referred to.

Title: Improvements in or relating to vacuum machines for filling bottles and the like containers with liquids
IPC: B67C3/26
Filed: 1947-10-04
Abstract: 639,737. Bottling. HARRISON, N. C. Oct. 4, 1947, No. 26748. [Class 125(ii)] A vacuum machine for filling bottles and like containers with liquids, or solids in liquids such as pickles or chutney, comprises two interconnected heads for engagement with similar containers, one e head being connected to a source of vacuum and the other head to a source of liquid in such a way that when the containers are in engagement with the heads the vacuum source is connected to the liquid source through the containers in series, so that the one head acts as an interceptor head and a container associated therewith acts as an interceptor vessel, while the other head acts as a filling head, and the container associated therewith is filled. As shown, filling heads 5 are joined to corresponding interceptor heads 6 by bars 7. A vacuum pipe 9 leads from each head 6 to an auxiliary interceptor 10 provided with a float valve and connected to the source of vacuum; the degree of vacuum is controlled by a valve 11. Liquid is supplied to each head 5 through pipe 8, via a non- return valve. Bottles are inserted between a platform 13 and heads 5 and 6. Air is withdrawn from the bottle beneath a head 5 through an annular duct 21 and passes via a passage 40 in the bar 7, a reducing valve 34, and a passage 29 through the interceptor bottle and thence through an annular duct in the head 6 to the vacuum pipe 9. Liquid passing through the vacuum line, after the bottle beneath head 5 is filled, is trapped in the interceptor bottle. When the latter is almost full it is transferred to head 5 to be completely filled, and a fresh bottle is applied to head 6. Platform 13 is adjustable vertically by means of a set screw 14 and the portion under each pair of heads 5, 6 is adjustable horizontally by a set screw 16; alternatively, the heads may be displaceable relatively to a fixed platform. Passage 40 is provided with scavenge ports closed by plugs 41.

Abstract: 412,457. Valve-gear for percussive tools. HARDYPICK, Ltd., and RAYNER, P. T., Mining Tool & Engineering Works, Heeley, Sheffield. Sept. 29, 1933, No. 26874. Addition to 412,431. [Class 122 (ii).] In a valve of the kind described in the parent Specification, the width of the orifices to the radial ports m in the valve chamber which are controlled by the rear end collar m<2> of the valve are equal to the width of the collar which is provided with a conical seat forward area r<1> to prevent leakage. The radial orifices are enlarged circumferentially at m<1> to provide a plurality of annularly arranged grooves. The intermediate collar p has tangential flats to admit live fluid pressure to the front of the cylinder when the valve is in its rear position. The collar cuts off the fluid supply to the forward end of the cylinder when the valve is moved to the right. Valve-chamber radial ports z<2> admit live fluid to the conical part of the valve when in its forward position to exert a constant rear pressure to accelerate the valve return when the piston passes the exhaust ports x. The valve is moved to the right by compression, and to the left by the pressure on areas r<1>, t.

Title: Improvements in and relating to quick-action clamping nuts
IPC: E04G17/065
Filed: 1966-06-16
Abstract: 1,144,826. Nuts. J. SEDLAK. 16 June, 1966 16 June, 1965], No. 26885/66. Heading F2H. [Also in Divisions El and E2] This invention relates to a quick-action clamping nut of the kind which has two parts 1, 2 mounted in a holder 3 so that they are movable between operative and releasing positions, the two movable parts having end portions which together form a frusto-conical projection 15 when the movable parts are in operative position, the movable parts when in operative positions being adapted to be screwed on a member carrying an external screw thread, for example a clamp bolt 6, and longitudinally slidable thereon when the movable parts are in releasing positions, the said movable parts during clamping being held in engagement with the screw thread by engagement of the said frusto-conical projection by a frustoconical recess provided in a pressure member 14 slidable longitudinally on the member carrying the screw thread. According to the invention the movable parts of the clamping nut form levers which are rotatably mounted about bolts 41 on the holder and one end portion of each of which carries half of the screw thread and the other end portion 7 or 8 forms a handle, the handles enabling the end portions carrying the screw thread halves of the nut to be separated, against the action of a spring 9, to releasing positions. One use for the nut device is part of a clamp, Fig. 3, the clamp comprising the nut, the clamp bolt 6 on which the nut is threaded and which includes a clamp jaw 16 and the pressure member 14 having a frustro which forms a second jaw if the clamp nut engages; the clamp shown is used to securing shuttering in position. Another use is for the vertical adjustment of telescopically extensible ceiling supports; in this case the nut device abuts against and is rotatable relative to a pressure member in the form of a tube forming the bottom portion of the support and the screw threads of the parts 1, 2 engage an external thread of an upper portion of the support which is inserted into the lower tube so that when the upper portion of the support is prevented from rotation, rotation of the nut will raise the upper portion of the support which can be released so that it can drop back into the bottom portion by means of the handles.

Title: Improvements in or relating to transistor bistable circuits
IPC: H03K19/09
Filed: 1959-08-06
Abstract: 915,762. Transistor bi-stable circuits. BUDTS, L., DE ROUMEFORT, F. DE S., and DE ROUMEFORT, (nee BALIGANT) J. DE S. Aug. 6, 1959 [Aug. 8, 1958; June 12, 1959], No. 26900/59. Class 40 (6). [Also in Group XL (b)] A bi-stable circuit comprising two transistors cross-coupled has a capacitor associated with one transistor so that, in the absence of an input, the circuit automatically assumes a preferred state when it is switched on. Fig. 3 comprises two transistors T 1 , T 2  having their base and emitters cross-connected so that the device has two stable states in which one or other of the transistors is conducting. A capacitor C ensures that when power is first applied to the circuit, in the absence of a control signal, it assumes the state in which T 1  is conducting. A switch I 1 , when operated, will cause the circuit to change its state and, when I 2  is open, opening switch I 1  will restore the circuit to its initial state. Operation of I 2  on its own will not change the state of the circuit but if I 1  and I 3  are both operated the circuit will hold the new state even if I 1  is released. The switches I 1  and I 2  may be constituted by the emitter collector circuits of transistors, the base of which may be connected to a light-sensitive cell (Fig. 5 and 6, not shown). The output from E may be applied to a further bi-stable circuit (Fig. 6, not shown), or to an amplifier (Fig. 9, not shown). Fig. 11 shows an alternative circuit in which a capacitor C 1  is connected in series with a resistor to the base of transistor T 2  to ensure that on first switching on, in the absence of a switching signal, transistor T 1  becomes conducting. Switching is effected through line X or X 1  and a diode D is provided to increase the sensitivity. Multiple outputs are obtained from parallel connected resistors 104, 105 and 106 or 101, 102 and 103, though in Fig. 16 (not shown), these resistors are replaced by diodes. Alternative coupling arrangements comprising diodes and series capacitors so that only impulses are passed are described with reference to Figs. 12-15 (not shown). These arrangements may be combined to form " AND," " OR " and " INHIBIT " connections (Fig. 17, not shown), and to perform other logic functions (Figs. 19-21, not shown). Coupling between a number of stages and a number of further stages may be effected by a single diode together with a number of resistors (Fig. 7, not shown), or by a number of diodes operating in parallel (Fig. 8, not shown). In addition to light-sensitive input elements magnetic induction sensitive elements, contactmaking switches or thermally-sensitive resistors may be used as the input switching elements and the output may be coupled through magnetic amplifiers to electromagnetic switching devices (Fig. 10, rot shown).
