Abstract: 468,852. Vulcanizers. BRIDGE & CO., Ltd., D. (National Rubber Machinery Co.) Jan. 16, 1936, No. 1394. [Class 70] In a watchcase vulcanizer the upper head pivots on a fixed shaft 14 disposed diametrically across the head and the lower head is pivotally mounted on two stub shafts 20 journalled in the ends of a forked arm 19 pivotally mounted on a fixed shaft 18. The two heads are hingedly connected by an adjustable shaft 33 which extends through bracket arms 31, 32, fixed to the upper and lower heads respectively. The arrangement constitutes a toggle. The machine is opened and closed by an electric motor 45 which, via pinion 44 and gear 43, rotates an internally-threaded sleeve 39 which thus travels along a screw 40 pivotally connected at 41 to the machine frame; the sleeve moves the housing 37 which is pivotally mounted on stub shafts journalled in rearwardly extending parts of the (two) arms 31. The medial portion of the shaft 18 is eccentric in relation to its ends and the angular position of the shaft may be varied to move the lower head towards or from the upper head. Switches (not shown) are provided on an end of the shaft 14, whereby the motor is automatically stopped when the heads have reached their fully opened or fully closed position. If the switches fail, serious over-running is prevented by stops 57, 58.

Abstract: 192,073. Schneeberger, F. Jan. 16, 1923. Spray carburettors.-The fuel nozzle is mounted in a semi-cylindrical valve the axle of which forms part of the fuel passage and air passes outside of and through the valve which may be removed to prevent unauthorized use of the engine. The valve c is mounted in a casing a and controls the flow of air to a mixing chamber b arranged tangentially to the casing. Fuel from the float chamber s, in which it is maintained at the level x, fows through conduit f and axial and radial passages in the valve to nozzle d mounted therein. The radial passage communicates with the atmosphere by duct g. Air can pass through the port y, z and also, in the more fully open positions, through ports c<3> in the valve itself. In the closed position of the valve a duct e therein is in communication with an opening m, Fig. 4, adjustable by a valve k, air then entering by nozzle d to form a no-load mix. ture. Further clockwise rotation of the valve brings the nozzle d into a position where it may be removed for cleaning or renewal. The valve c is retained by a spring o by turning which the valve may be removed to prevent unauthorized use of the engine. A valve may be arranged in the conduit f. In a modification, the nozzle is situated outside the valve body. In each case the height of the nozzle outlet above the fuel level varies with the turning of the valve.

Filed: 1942-02-04
Abstract: 570,390. Panoramic receivers. JEFFERSON, H. Feb. 4, 1942, No. 1498. [Class 40 (v)] In a panoramic receiver of the superheterodyne type, the local oscillation is derived by combining in a frequency changer the continuously varied frequency from a frequency sweep oscillator and the manually adjustable frequency from a second oscillator so that the relatively narrow band swept over may be placed anywhere in the total tuning range of the receiver. In the Figure, a sweep oscillator 10 is continuously varied over a range of 500 k.c. by a time base unit 11 and the output is combined in a frequency-changer 9 with the output from an oscillator 8 which is provided with manual tuning means over a range of 3 x 10<3> k.c. to 30 Î 10<3> k.c. The output from 9 is fed through an amplifier 6 to the signal frequencychanger 3 fed by the tuned radio-frequency stages 1, 2. The intermediate frequency after passage through a detector 4 and D.C. amplifier 5 is fed to one set of deflecting plates of a cathode-ray tube 7, to the other set of plates of which is supplied. a scanning voltage from the time base unit 11. The arrangement may be such as to indicate the strength of the received signal either by the length of the trace or by the brilliance. Alternately the trace may be received on a moving photographic film so as to record the tune and wavelength of the reception. The tuning of the amplifiers 1, 2, 3 and 6 is gauged with that of the oscillator 8 so as to shift the mid-band synchronously through the frequency spectrum. Specification 570,391 is referred to.

Abstract: 619,670. Vehicle-moving apparatus. MAVOR & COULSON, Ltd., ANDERSON, J., and FRASER, A. Jan. 24, 1945, No. 1969. [Class 78 (iv)] Vehicle-moving apparatus includes two fluidpressure rams 23, 24, which engage directly with the vehicles 19 ; and control means for controlling the operation of the rams, the ram 24 advancing the vehicle to the loading station and the ram 23 moving the vehicle forwards in the loading station for trimming the load. As shown, coal from conveyer 8 falls down chute 5 (which is oscillated by link 11 from power-operated arm 10) and enters stationary hopper 9 where it is fed through door 12 which is worked by link 15, bell-crank lever 18 and hydraulic ram 17 in conjunction with ram 24 which pushes successive empty wagons 19 into place beneath the door whilst the latter is closed, and in conjunction with auxiliary ram 23 which takes over the movement of the wagon and moves it forward slowly so as to distribute evenly the coal that falls when the door is opened. Rams 23, 24 roll on wheels 26 having platforms 25 and catch bars 28 which push the wagons by their axles 29. The valves controlling the hydraulic system are valve 38, the tappet 42 of which is automatically motivated by leyer 18 ; valves 33, 34, the handles 35, 36 of which are worked by an operator, each having three positions ; and valve 37, the tappets 39, 40 of which are automatically operated by striker 41 on ram 24. Semi-automatic operation. Commence with door 12 closed, i.e. ram 17 extended, and rams 23, 24 drawn backwards. Operator moves lever 36, so that ram 24 moves empty wagon forward and striker 41 operates valve 37 so that ram 17 is retracted. Accordingly, coal falls and valve 38 is automatically struck so as to stop the forward movement of ram 24. Operator moves lever 35 so that auxiliary ram 23 moves the wagon forward, moves lever 36 so as to retract ram 24 and thus to actuate valve 37 in the reverse direction and, when the operator observes that the wagon is full, he moves the lever 35 again so that ram 23 retracts and finally he moves lever 36 again so that ram 17 advances, closes door 12, and operates valve 38 so leaving the apparatus ready for the next wagon.

Abstract: 1,043,721. Monitoring distance measuring systems. ELLIOTT BROS. (LONDON) Ltd. Jan. 10, 1964 [Jan. 16, 1963], No. 1986/63. Heading H4D. In distance measuring equipment of the kind wherein transmitted and corresponding received echo energy (either electromagnetic or acoustic, pulse or C.W.) is compared to give a parameter indicating the return time of the energy, and thus, the distance of the reflecting object, a second receiver is provided whereby a second like parameter may be simultaneously derived for comparison with the first derived parameter to derive any difference therebetween and monitor said equipment. In the arrangement shown, energy from transmitter 1 is reflected by object 3 and fed to normal receiver 5, and, via a delay means 7 which introduces a delay representing a known distance, to monitoring receiver 6. A signal representing the distance of the object 3 is produced by distance computer 8 and fed, via line 12, to display means, and also to comparison means 10. The monitoring receiver 6 also provides a distance signal from computer 9 which is fed to comparison means 10. The comparison means is biased by unit 11 to take account of the delay introduced by means 7, such that it only gives an output to actuate alarm 14 when the two receivers 5 and 6 fail to give identical target distances, ignoring the artificial distance introduced by delay means 7. The delay means 7 and biasing unit 11, are provided such that the comparison means 10 produces an alarm actuating signal when both receivers fail to give an output.
