Title: Improvements in apparatus for applying material to cores, particularly applicable to the insulation of cable conductors
IPC: B29C48/06
Filed: 1927-11-14
Abstract: 305,688. Beatty, W. E. Nov. 14, 1927. Extrusion machines. - Means for applying layers of material to cores, particularly for applying layers of insulating material to an electric conductor, comprises a tubular member having inserted dies of progressively larger bores for forming successive layers of material upon a core passed through. In the embodiment is shown apparatus for applying three layers of insulation to each of four independent conductors. A die block 9 is inserted in a tapered opening 8 in a frame 7, and comprises an annular part 12 which tapers to an elliptical part 13. Externally-threaded, die members 18, 22, 23, and progressively larger bores, are screwed in internally threaded tubes 17 which are carried by the block 9. The material for the first layer of insulation passes from an annular reservoir 15 through channels 26 into the die 22, the material for the second layer passing to the die 23 through channels 28. The third layer of insulation passes through a screen 31 belore reaching a die 24 mounted in a face plate 25. In order to adjust the opening between the dies 23, 24 the tube 17 is moved longitudinally by a threaded lug 33 on the tube which is engaged by a threaded rod 32 formed with a square head 34. A tube 20, superposed on the tube 17, and formed with openings which normally allow passage of the material, is rotated to cut off the supply of insulating material to the dies 22, 23.

Title: Apparatus for indicating working conditions in internal combustion engine cylinders
IPC: G01L23/22
Filed: 1961-08-25
Abstract: 956,859. Indicating working conditions. ESSO RESEARCH & ENGINEERING CO. Aug. 25, 1961 [Oct. 7, 1960], No. 30671/61. Heading F1B. Apparatus for timing the occurrence of peak pressure or the arrival of the combustion flame at a point in an I.C. engine cylinder 22, Fig. 1 with respect to the rotational displacement of the crank-shaft comprises devices 1, 2 for indicating flame arrival and peak pressure either of which electrically initiate a counter mechanism 16 to count or to terminate counting a series of pulses from a pulse generator 11, and pin/magnet means 12, 13 associated with the engine which stops or starts the counting at a predetermined point of rotation. When the flame reaches ion gap 1, direct current from power supply 24, is conducted, through an amplifier 6 to a pulse shaper 9 which, at a given intensity of signal, transmits a sharp clearly-defined signal to counter 16. Pulse generator 11 is driven directly or by belt from the engine, and emits an electric impulse for each degree of crank-shaft rotation to the counter 16 which, when initiated by the signal from pulse shaper 9, commences counting. A pin 12, of paramagnetic material, secured to the flywheel 21, induces a current in the coil of a stationary magnetic pick-up 13 which acts to make counter 16 unresponsive to the electric impulses from pulse generator 11. The rotational position of the pick-up 13 may be varied and any part moving cyclically in synchronism with crankshaft 23 may be used to drive the pulse generator. A record of transmitted data is obtained in a recorder 20 which is connected to the counter 16 through a printer 19. In a modification the pick-up 13 can initiate counting whilst the arrival of the flame at ion gap 1 stops the counting. Alternatively, the electric signal from a quartz crystal pressure pick-up 2 is passed through a differentiating amplifier 4 which passes the derivative of the signal to the pulse shaper. 9. In another embodiment the device is applied to an 8-cylinder I.C. engine.

The non-magnetic material may be of various shapes and need not be homogeneous in the direction of the lines of force in the gap. If two separate pieces of non- magnetic material are placed in the gap that nearest the window is preferably of a material mechanically less rigid than the other.

Abstract: 244,767. Pestourie, P. Dec. 17, 1924, [Convention date]. Vibration-dampers are constructed with a drum and a relatively rotatable hub in two parts which are expanded against the drum by a spring in such a way that the frictional resistance increases with increase of displacement from the normal position. In the form shown in Figs. 1 and 2, the drum 1, having a lining 3, is connected by means of an arm 2 to the axle of a vehicle while the fixed segment 5 projects from a base 4 secured to the vehicle frame. The loose segment 6 forming the other part of the hub is expanded against the lining 3 of the drum 1 by a spring 7 having at one end a ball-type abutment 9, 10 engaging the segment 6 and at the other end a similar ball-type abutment 12, 13 engaging the drum 1, the sleeve 13 passing through a slot 14 in the segment 5, and the position of the abutment being adjustable to vary the pressure of the spring. When the vehicle is normally loaded the spring should be along a diameter of the drum so that movement in either direction will shorten it and increase the friction between drum and hub. In a modification, the separate balls 9, 12 are dispensed with, ball joints being provided. The drum may be mounted on the frame and the hub connected to the axle.

Abstract: A lime containing dephosphorizing material, carrying in a stream of oxygen is injected with a kinetic energy sufficient to ensure deep penetration into a bath of pig iron held in a tuyereless converter from a nozzle above the surface of the bath. Said material is mainly constituted by industrial lime to which are added fluxing agents such a fluorspar, iron or manganese oxides, sodium or magnesium oxide, carbonate, or hydrate, or any other material capable of lowering the melting point of the lime. Its grain size should be below 10 mm. with 75 to 80% above 0.2 mm., unless a prefabricated slag is used, the particles of which may be smaller.  Some may be added to the bath in bulk, the injection of the remainder occupying the whole or a part of the time of conversion.  The process may be carried out in two or several phases, not all in the same apparatus, with, if needed, an intermediate recarburization.  Specification 822,271 is referred to.

Abstract: 324,665. Avery, Ltd., W. & T., and Timson, W. Oct. 31, 1928. Pendulum - weight apparatus; computing- apparatus.-An automatic weighing-scale of the kind employing a pendulous resistant and wherein the scale plate is mounted on a lever system which has connection at one end with a weight indicating mechanism disposed above the scale plate is characterised in that the pendulous resistant is disposed below the scale plate and at the opposite end of the lever system to that which has connection with the weight indicating mechanism. A weighbeam 9, fulcrumed on a knife-edge 10, supports a scale plate 5 at one end and carries at the other end a cradle 16 connected to a rack rod 20 actuating a circular weight-and-value chart 25 secured to an annular weight chart 26. Fixed price and weight indices 28, 27 co-operate with the two charts, and an additional value strip index 71 is automatically brought into view as described below when the weighing capacity is increased. The weighbeam is connected by a link 32 to a lever 33 bearing upon the centre of a yoke 35 coupled by flexible ribbons 36, 37 to a pair of oppositelydisposed pendulums 40<a>, 41a situated below the scale plate. A dash-pot 49 is connected to the weighbeam. In a modification, the pair of pendulums is disposed parallel to the weighbeam. A single pendulum may be used instead of a pair. In a further modification, an horizontal cylindrical indicator is employed instead of the disc charts. Loose-weight apparatus.-The cradle 16 resting on the weighbeam is provided with a pair of jaws 16<b> to receive the trunnions 51<a> of a capacity weight 51 when this is transferred from fixed jaws 52<a> during a capacity-increasing operation. The operation is effected by turning a handle attached to a shaft 54 thereby rotating a fork 53 which engages the trunnions of the capacity weight and effects its transfer, the two sets of jaws 16<b>, 52<a> being brought into correct opposition for the transfer by the action of a linkage 56, 57 upon the weighbeam. A crank arm 61 on the shaft 54, at the same time actuates a rod 62 and rocking arm 65 so as to give a small angular displacement to a disc 67 loosely connected with the two dials. The disc 67 then displays at orifices 25<a>, a new series of weight numerals appropriate to the changed capacity of the machine. An arm 69 projecting from the rod 62 actuates a rod 70 connected to the pivoted value index 71 and moves the index into view as shown in Fig. 2. The values given by the index 71 are added to those taken from the computing chart 25 when the capacity weight is in operation.
