Title: Improvements in or relating to screening apparatus
IPC: B07B1/28
Filed: 1928-10-18
Abstract: 312,565. White, A. E., (Robins Conveying Bel't Co.). Oct. 18, 1928. Sieves with compound motion.- In apparatus for screening coal, coke, crushed stone, ore, sand, gravel, &c. a rotary shaft mounted in stationary bearings imparts to the screening element a positive gyratory movement in circular paths at right-angles to the shaft and a resilient support is provided to maintain the screening element in its correct position by acting thereon simultaneously in the same direction on both sides of the shaft. The resilient support also acts as the means for varying the inclination of the screen. In the construction shown, Fig. 3, a frame 27, which may be in two parts bolted together is clamped on a tubular shaft 23 and carries two superposed screens 26. The shaft 23 has a bearing in an annular eccentric 22 provided on a rotary shaft 14 which works in fixed bearings on the supports 11. Preferably, the eccentric is of the adjustable type comprising two concentric members of equal eccentricity, and is formed in one with a flywheel 18 carrying adjustable weights 16 to balance the centrifugal force of the screen. The screen frame is supported by leaf-springs 48 and upright and pendent links 52 as shown in Fig. 1. Adjustment of the inclination of the screen is obtained by securing the springs at their midpoints to frames 37 pivoted to the supports 11 at their upper ends 39. A shaft 43 carried by the frames carries pinions 45 engaging with segmental racks 46 on the supports. Studs 40 carried by the lower part of the frames 37 work in arcuate slots 41 in the supports and are clamped to secure the screen frame in any required position. The screens 26 are stretched over upwardly curved supporting bars 31 to prevent whipping by clamps 32 and tensioning screws 33. Preferably the feed ends of the screens are made independently removable to allow for extra wear and replacement of these parts of the screen.

Title: Improvements in or relating to a fail-safe protective circuit for a circuit controlled by a magnetic amplifier
IPC: H02H5/04
Filed: 1958-09-22
Abstract: 839,736. Magnetic amplifiers. VAPOR HEATING CORPORATION. Sept. 22, 1958 [Oct. 21, 1957], No. 30261/58. Class 40 (9). [Also in Group XXXV] In a windshield defrosting system in which a resistance bridge 12 includes a temperaturesensitive resistor 24 embedded in the windshield glass 11, the output of the bridge is applied to the control winding 38 of an auto-self-excited bridge rectifying transductor 13 controlling a relay 47 in the circuit of the windshield heater 10, and is also applied over a rectifier 55 to a fail-safe winding 52 which is energized only when the bridge potential exceeds a predetermined value. The fail-safe winding acts in the same sense as a bias winding 40, and when energized swamps the action of the control winding so that the amplifier output falls to its minimum value. The predetermined voltage above which the fail-safe winding becomes operative is determined by the non-linear characteristic of the rectifier in the conductive direction. The arrangement ensures that the windshield is not overheated in the event of failure in the resistance bridge of such a nature, e.g. an open circuit in bridge arm 20 or 22, as to establish continuous energization of the control winding.

Title: Improvements in and relating to electric tachometric devices
IPC: G01P3/49
Filed: 1946-10-11
Abstract: 618,003. Speed indicators. FURZEHILL LABORATORIES, Ltd., MILSOM, F. R., KANTOROWICZ, O. P. T., and SMITH & SONS (ENGLAND), Ltd., S. Oct. 11, 1946, No. 30458. [Class 40 (i)] An electric tachometer comprises a conductor 10 rotated by the device whose speed is to be measured, a field magnet 15 having a winding 17 excited from an A.C. source, and a pick-up magnet 18 having a winding 21 in which is induced a voltage dependent upon the speed of the rotating conductor. The magnets are so disposed that the magnetic field between the poles of the field magnet 15 traverses the conductor and the interpolar space of the pick-up magnet 18 and when the conductor disc 10 is stationary the voltage induced in magnet 18 is substantially zero. When the conductor 10 is rotated at a speed within the operative range of the instrument, a further voltage, 90 degrees out of phase, is induced in the winding of the pick-up magnet which voltage is substantially proportional to the speed of rotation of the conductor. This voltage may be applied to a voltmeter calibrated in speed or may be used to control the speed in known manner. In view of the phase difference between the residual voltage and the voltage induced by rotation, a wattmeter arrangement or valve amplifier or the like may be used to pick up the voltage dependent on the speed. The valve amplifier, Fig. 4, comprises two valves 31, 32 with their anode-cathode circuits fed in parallel through the centre-tapped primary winding of a transformer 33, from the A.C. source between terminals 34 and 35 which supplies the field magnet 15. Phase-adjusting means 36 may be provided. Voltage from the pick-up winding 21 is fed through a transformer 37 to the grids of valves 31, 32 and the means 36 are adjusted until the phase of the anode current is substantially the same as that of the voltage to be selected, i.e. the voltage produced by rotation of disc 10. Means, such as a pin-and-slot arrangement, are provided to enable adjustment of pick-up magnet 18 relative to field magnet 15. The disc 10 may be replaced by a cup-shaped conductor, with corresponding modification in the arrangement of magnets. Various forms of magnet windings may be used, and temperature compensation means may be provided.

Title: Improvements in or relating to a device for use on firearms to enable them to be used as air guns
IPC: F41B11/647
Filed: 1949-11-28
Abstract: 675,005. Air guns for firearm practice fire. BERTSCHINGER, J. Nov. 28, 1949. [Dec. 1, 1948] No. 30501/49. Classes 92 (ii) and 119. Relates to firearms adapted for practice fire with small pellets by inserting an air gun into the breech and bore of the firearm after removal of the breech bolt. According to the invention, the piston of the air gun, which is cocked against strong spring action, is retained in cocked position by a device relieving the pressure of the air-gun spring on the trigger-operated sear of the firearm, which device is automatically released following release of the sear. In the form shown in Fig. 1, the firearm to be adapted is shown in chain lines, the air-gun attachment, held by a leafspring clip 20 being shown in full lines with, the air-piston 6, and air gun barrel 3 attached thereto, moved rearwards for cocking into engagement with a rear member 16 arranged between the firearm sear C and the bent 9a of the yielding sleeve 9 of the air-gun piston. Fig. 4 shows in plan the lever mechanism for cocking the air-gun piston spring 14. On swinging a lever 23 clockwise about pivot 26, a connecting link 22 acts to slide a bar 21 on the air cylinder 1, a projection 21a on the bar engaging a member 5a on a sleeve 5 fast with the air barrel 3 thereby compressing the spring 14 against a fixed abutment 2 and moving the air piston 6 until the bent 9a, Fig. 6, moves past sear 16 and engages by spring arms 13 with a stop-ring 12 to retain the piston in cocked position. On release of the triggeroperated gun sear C, the member 16 is moved forwards by the bent 9a and, whilst extending the spring 19, is rocked aside by a cam surface 16a, the full force of the air spring serving automatically to release the spring arms 13 and the air piston. Air under pressure is then forced through holes 3a into the air barrel to expel the pellet loaded by a removable plug 15.
