Abstract: 1,064,808. Screw conveyer for silo. LAIDIG SILO UNLOADERS Inc. Sept. 29, 1965 [Dec.10, 1964], No. 41342/65. Heading B8A. A silo is discharged by a screw conveyer 15 which is drivingly rotated by motor 29 and is caused to gyrate by motor 31 carried by the casing of conveyer 15 and operating via gear 34 and fixed rack 35. To avoid overloading the conveyer 15 electrical circuit includes solenoid 42 (Fig. 4, not shown) and switch 44, 45 so that an increase of current through motor 29 caused by the increase of load of material in the silo placed upon screw 15 causes the movement of element 43 to break switch 44, 45 and slow down or stop the motor 31. When the load diminishes the decrease of current in motor 29 permits the resetting of switch 44, 45 and recommences the motor 31 so that the screw 15 recommences its sweeping movement.

Filed: 1974-08-01
Abstract: 1473306 Detecting metal objects DEFENCE SECRETARY OF STATE FOR 1 Aug 1974 [11 Sept 1973] 42656/73 Heading G1N An inductive loop detection apparatus includes an inductive testing loop inductively coupled to the detecting loop and which simulates an object to be tested e.g. a motor vehicle or aircraft travelling along a road or runway. A twin core cable buried under the road or runway and arranged in the form of a loop has one core 6 coupled to a conventional impedance detection apparatus 7 and the other core 5 forming a testing loop connected to a test circuit including impedances Z1-Z6 and a 2- pole twelve way electromagnetically operated switch 1, 2, 3, 4. When the wipers 3, 4 are in the position shown loop 5 is in open circuit and has very little effect on the normal operation of detection loop 6. To test the detection circuit 7 push switch 8 is pressed to cause current to flow through magnet coil 10 of the switch and move wipers 3, 4 to contacts C 2 , C 2 ' and cause impedance Z 1  to complete a circuit with coil 5. This has a similar effect on the coil 6 and circuit 7 to that of a metallic object close to detecting loop 6. Due to the connection of the circuit shown current continues to flow in coil 10 to move wipers 3, 4 to the next position C 3 , C 3 ' to open circuit testing coil 5 so that the effect at detection loop 6 is of an object moving over the detecting loop. Each time button 8 is pressed the switch moves round two positions to connect a successive one of the impedances Z1- Z6 into circuit with the testing loop 5, the impedances decreasing in impedance so that the effect is of successively larger objects. Thus the sensitivity of the apparatus can be measured.

The assembly is intended for GRP panels in ships. As shown, the fastener 1 has external knurling 6 and is a force-fit in the bore 8. An annular annular groove 7 is pressed into the external surface of the fastener to deform the thread in the bore 5 to make it self-locking.

To assist in applying the compound 12, a selfadhesive disc 13 having a tab 14, an injection hole 15, and a breather hole 16, is stuck over the counterbore while the compound is injected and cured. The disc is then removed, using the tab 14.

Abstract: 1,270,749. Measuring pulse duration: peak detection. SUN ELECTRIC CORP. Sept. 9, 1970 [Sept. 9, 1969], No.43204/70. Heading G1U. In order to determine the duration of pulses 1a, Fig. 1 which occur at a varying frequency, the pulses are shaped 6 to produce rectangular pulses 16, converted to sawtooth pulses 1c having peak amplitudes corresponding to the duration of the input pulses, and the peak amplitudes are detected Det 1 and displayed 11, 12. In order to avoid jitter on the display the time constant R1, C2 of the detector Det 1 must be sufficiently long, which has the result that although the detector can follow abrupt rises in peak amplitudes it cannot follow abrupt reductions. This defect is overcome by effectively short circuiting capacitor C2 momentarily whenever an abrupt reduction occurs: once the short circuit is removed the output of the detector rapidly rises to the new (much reduced) peak amplitude of the input pulses. Shorting of the capacitor C2 is controlled by a second detector Det. 2, in parallel with the first, and a comparison circuit 13. The second detector is arranged to have a short time constant R8.C4 so that it can follow abrupt reductions in peak amplitude, and the comparator 13 is arranged to open a shunt 14, effectively short circuiting capacitor C2, whenever the output of the second detector becomes more than a pre-set amount lower than the output of the first detector. A comparator circuit Fig. 2 (not shown) is described in which the outputs of the two detectors are fed via a cathode-follower to the two grids of a mono-stable triode pair; when sufficient unbalance in the appropriate direction occurs the mono stable switches - switching being aided by a common cathode constant current load - to discharge the first detector.

Title: Improvements in the production of mineral wool
IPC: C03B37/05
Filed: 1963-11-08
Abstract: Mineral wool is produced by directing a stream of molten mineral on to a part of the periphery of a rotor rotating about a substantially horizontal axis, and directing a hot blast of gas traversely and axially of the rotor on the centrifugally extended tangential molten stream, thus shredding the stream into fibres which are projected into a collecting chamber.  The gas, which may be air or steam, may emerge from an apertured annular conduit, and the blast may be spaced from or directed into contact with, the periphery of the disc.  In Fig. 1 (not shown), molten slag falls from furnace 5 through opening 4 on to the periphery of rotating disc 3.  Steam emerges through aperture or apertures of annular conduit 6 and projects the fibres through opening 8 into blow chamber 9. The outlet apertures 7 may be V-shaped as at 7c in Fig. 4 (not shown), or may be simple holes, or a single elongated circular slit.  In a particular embodiment, the temperature of the stream emerging at 4 is 1450 DEG  C., the pressure of the steam blast is 8 atmospheres, and the disc rotates at 2000 r.p.m.
