IPC: B29C65/04
Filed: 1946-11-13
Abstract: 633,082. Splicing threads. FIRESTONE TIRE & RUBBER CO. Nov. 13, 1946, Nos. 33690 and 33691. Convention dates, June 20. [Class 120 (iii)] Two lengths of organic thermiplastic monofilament are joined to form a continuous filament by overlapping them in parallel relationship and welding them together at the overlapped surfaces by means of a high frequency electrical current. As shown overlapping monofilaments 26, 28 of 25-400 circular mils cross-sectional area are inserted in a slot 41 in a lower electrode assembly 24, resting on the lower electrode 38 which is sandwiched between two glass plates 40 and two insulating blocks 42. The upper electrode 66 having a working edge 73 adapted to enter slot 41. The two electrodes are shaped to abut only along the desired length of weld. Depression of pedal 34 causes the upper electrode assembly to be pressed under the action of spring 91 against the lower assembly so as to press together the monofilaments with a pressure of from about 3 lb. to about 6 1b. per linear inch, and also closes a limit switch 100 to apply by means of a high-frequency generator 36 an e.m.f. to the electrodes having a frequency of 150 to 250 megacycles/sec. for a period of 15-30 secs. after which the circuit is broken by a time switch. The walls of blocks 40 adjacent the filaments may be coated with oil to avoid arcing around the filaments. The excess ends 23, 25 of the filaments may be cropped after welding by chisels which are slidably mounted in the lower assembly 24 and which may be operated manually or automatically by pneumatic or electrical means. In an alternative construction, the working edge of each electrode is flush with the edges of the supporting insulating blocks, and is provided with a longitudinal groove of a depth less than the thickness of a filament, into which one of the filament ends is clipped. The mono-filaments may be of nylon or of a vinylidene chloride base mono-filaments of plastic composition reinforced by fine textile filaments, such resin, or may be solid as "textron."

Abstract: 866,121. Air - spring suspensions. GUY MOTORS Ltd. Oct. 19, 1959 [Oct. 23, 1958], No. 33902/58. Class 108(2). A rear bogie in a road vehicle has its front and back axles each independently mounted on a respective pair of beams 13, 14. Each beam is partially supported by at least one air-spring 18, 19 acting between the beam and the main part of the vehicle. A pressure equalising air connection 20 acts between the springs 18, 19, and air is led to or from the springs by way of a control valve 21 and levelling valves 22. The control valve is only operated in response to displacement of the mean level of the ends of'the axles relative to the chassis as on change of load or on acceleration or deceleration. The levelling valves may be omitted if other means are provided to prevent the bogie and chassis from becoming misaligned. A resilient link may be interposed between the link 21 and the operating member 23 to avoid operation of the control valve when there is appreciable movement of the centre of link 24 on rocking of the bogie or of the axles occurring. The construction may be modified (Figs. 2, 4, 6, not shown) by replacing the beams 13, 14 by beams which are each supported at each end by an air spring. These four air springs are connected by a common pressure equalising connection. Alternatively the leading air springs of the two wheels may be provided with a pressure equalising connection and the trailing air springs provided with a separate connection.

Abstract: 896,013. Gas turbine jet propulsion plant. PLESSEY CO. Ltd. Oct. 31, 1958 [Nov. 1, 1957], No. 34115/57. Class 110 (3). [Also in Group XXIX] The area of a jet propulsion nozzle of a gas turbine engine is controlled by a piston or diaphragm subject on one side to the pressure in the jet pipe and on the other side to a pressure between two series-connected metering orifices in a bleed from the turbine-driven compressor to atmosphere, the areas of both orifices being unaffected by flow and pressure conditions. A compressor 11 supplies air to combustion equipment 12 feeding a turbine 13 driving the compressor. The turbine discharges through a jet pipe 14 and a variable area propelling nozzle controlled by flaps 16. The flaps 16 are operated by jacks 15 in response to the pressure in conduit 7. The pressure in conduit 7 is controlled by a piston or diaphragm 51 acted on one side by the pressure in the jet pipe 14 and on the other side by the pressure between two metering orifices 31, 32 connected in series in a line 2 connecting the compressor discharge to atmosphere. This pressure bears a constant ratio to the compressor discharge pressure and the ratio may be adjusted by a screw 33. The piston 51 controls a valve 6 which connects the conduit 7 either to the compressor discharge through the line 2 or to atmosphere through the port 61 according to variations of the ratio of the jet pipe, to compressor discharge pressure until the original ratio is restored when the line 7 is isolated. To avoid hunting, the valve 6 may be connected to a balance lever which couples the piston-rod 52 to the flap members 16.

Filed: 1936-12-11
Abstract: 477,653. Electrical musical instruments. BALDWIN CO. Dec. 11, 1936, No. 34141. Convention date, Dec. 11, 1935. [Class 88 (ii)] [Also in Group XL] In an electrical musical instrument, threeelectrode glow-discharge oscillators are employed, master - oscillators stabilizing other oscillators of a series to maintain them in tune. Successive oscillators of a cascaded series may be separated by an octave or other harmonic interval, and each oscillator impresses a pulsating voltage on the grid of its succeeding oscillator. Fig. 2 shows three three-electrode glow-discharge oscillators O1, 02, 03 yielding (say) C's in three successively lower octaves. Eleven similar series are provided for the other notes of the octave-scale. The master-generator O1 is a stable grid-coupled inductive oscillator, the lower generators 02, 03 being simple relaxation oscillators without inductances. A portion of the oscillating output voltage of master-generator O1 is impressed, by the connection RC, on the grid of oscillator 02, which, unless its natural oscillation period differs by more than 5 or 6 semitones, is pulled into tune at half the frequency. Combined outputs are led to an amplifier A and loudspeaker LS through transformers T1, T2 and devices TC1, TC2. At TC1, harmonics are added or accentuated to give string or reed quality, and at TC2 harmonics are filtered out to give flute quality ; in either case, scale notes are equalized in intensity by the appropriate selection of resistances R6 and of the primary impedances of the transformers T1, T2. By making resistances R5 large, pitch or intensity is not affected by playing several notes simultaneously. An alternating voltage of 4 to 6 cycles per second may be supplied from a generator G to the grid of the master oscillator O1 to vary its bias periodically in order to produce a tremolo. U.S.A. Specification 2,046,463 is referred to.

Abstract: 306,651. Lõchler, A. Dec. 17, 1927. Single.type composing and casting machines ; keyboards. - In singletype composing and casting machines having sliding matrix-bars mounted on a rotatable drum, a combined electrical and mechanical device is employed for positioning the matrices. The matrixbars 3, Fig. 2, each of which carries a complete fount of matrices, are mounted in guides in rings 2, which can rotate on discs secured to a shaft 1. The series of matrix-bars is rotated by hand to bring the required bar over a mould 12. The individual matrices, which are spring-supported in the bars, are depressed on to the mould by an electromagnet. The selected matrix-bar is engaged at its ends between detent-pins 7 supported by a bar 9a, which is secured to a nut 10 adapted to travel on a rotatable threaded spindle 9. On depression of a key 16, Fig. 4, of the keyboard, an electric contact 23 is made, whereby one of two electric clutches is closed, and the spindle 9 rotated, so as to traverse the matrix-bar to right or left, as required. One of two control cylinders 15, containing staggered perforations, is simultaneously caused to rotate. Depression of the key releases one of a series of levers 21, a pin on which enters a perforation in the control cylinder, and arrests it, and consequently the spindle 9, with the required matrix in position. The movement of the lever 21 breaks the electric circuit, and disconnects the driving means of the spindle 9 and drum 15. The lever 21 is re-set by a cam 32, and the cylinder 15 and spindle 9 are returned by springs. Moulds.-The mould comprises four movable jaws 37, 37<1>, Fig. 9, which are adapted to embrace the matrix. The jaws are mounted to slide in two guide-pieces 38, which can themselves slide in a frame a. The gude-pieces 38 are held against the inclined sides of the frame a by springs d, and are pressed towards each other by rods 40 and a cam-ring 42, against the pressure of springs 43. The movement of the jaws 37 is controlled by bell-crank levers b, connected to the rods 40. When released from the mould, the cast type falls into an aperture 48, Fig. 12, in a rotatable wheel 44, the aperture being normally closed by a spring-pressed pivoted plate 50. During rotation of the wheel, the plate 50 is depressed by a. cam, and the type slides down it to a position in front of an assembly-pusher. Trimming type.-The bottom of the type in the mould is cleaned by a knife on the rotatable wheel 14.
