Abstract: 1393820 Feeding irregular shaped objects on to a conveyer belt SPHERE INVESTMENTS Ltd 6 Sept 1972 41291/72 Heading B8A [Also in Division F2] Pieces 11 of rock are fed from a hopper 10 by a shoot 15, 16, to a conveyer belt 21. The latter runs at a speed greater than that of the rock pieces whilst they are on the shoot. A roller 25 presses the rock pieces into engagement with the belt 21. By this means the rock pieces are accelerated and are thus separated to an extent which facilitates automatic sorting. The shoot is made of a heavy cast material of iron based cobalt nickel alloy of 1 inch thickness. A lower portion 8 is formed with corrugations to guide the rock pieces. The roller 25 (see Division F2) comprises discs 26 of neoprene (Fig. 2, not shown). In a modification (Figs. 3 and 4, not shown), the roller 25 and the conveyer roller 22, are fluted so as to conform with the grooves in the shoot part 18.

Abstract: 1,002,534. Gas turbine engines. PLESSEY CO. Ltd. Nov. 30, 1961 [Dec. 2, 1960], No. 41502/60. Heading FIG. [Also in Division G3] Apparatus for controlling the supply of fuel to a gas turbine engine during acceleration comprises an engine-driven fuel pump 3 fed by a booster pump 2 and discharging through an adjustable orifice 22 to the interior of a piston valve 15 and thence by way of ports 23 to a conduit 7 leading, through a manually adjustable throttle valve 8, to main and pilot burners 11, 12. The pressure difference across the orifice 22, which is a function of engine speed, acts in opposition to a spring 35 to position the valve 15, and a spring-loaded valve 25, slidable in the valve 15 and controlling drain ports 30 therein, is subject to the pressure drop across the ports 23 and maintains that pressure drop at a substantially constant value. As described in Specification 996,001, an engine driven governor 13 controls an outlet between the ports 23 and the throttle valve 8 and is adjustably loaded by pressure in a conduit 14 which pressure may have a high or a low value depending upon the position of the valve 8. A spill valve 10 maintains a constant pressure drop across the valve 8. The valve 15 is rotated in its housing by gearing 18, 20.

A cartridge type hypodermic syringe has a tubular barrel 1 which may be loaded with a cartridge 2 through a longitudinal opening 14 and which has an apertured front closure 13 and an inner protuberance 9 which bears against a shoulder on the cartridge to prevent it being displaced lengthwise. The barrel is made of transparent or opaque metal or synthetic plastic and has a finger hole on the side of the barrel opposite the opening for assisting in the removal of a cartridge. A filler 9, extending less than 180 degrees around the barrel, projects into the barrel near the distal end and, when the cartridge is in the barrel, engages the rear surface 10 of a needle hub 4 on the cartridge. The front closure 13 of the barrel has an aperture which permits the passage of a sheathed hypodermic needle 15, but is smaller than the internal diameter of the cartridge. A push-rod 6 which passes through a rear closure 22 of the barrel engages a threaded stud 5 on a rear plunger 3 which closes the cartridge. In an alternative construction, the fillet is replaced by a flange which extends inwardly from the front edge of the longitudinal opening and a spring latch bears against the rear of the cartridge to keep it in position.

The adjustable frequency standard of Specification 1,160,794 has a modified frequency synthesizer which includes an " offset " oscillator 34 whose output is combined with that from the main oscillator 11 to produce the synthesized frequency which, after multiplication, is compared with the atomic standard. The frequency at which the standard operates is changed by changing the crystal in the oscillator 34. In order to stabilize the frequency of the oscillator 34 its output at 1 Mc/s.  250 N c/s. is frequency changed down to 250 N c/s. in mixer 41 and is fed to a phase discriminator 39 where it is gated with a 250 c/s. signal derived from the 5 Mc/s. oscillator 11. The phase comparator, Fig. 3, utilizes a field effect transistor 61 to sample the 250 N cs/s. signal and produce an error voltage across capacitor 57. This voltage is integrated in filter 88 and the resulting error signal used to control a varactor diode 72 in the oscillator 34. An alarm is initiated if the oscillator 34 becomes unlocked.

Abstract: 1455056 Protecting converters SIEMENS AG 4 Oct 1974 [5 Oct 1973] 43215/74 Heading H2F [Also in Division H3] An arrangement for protecting a thyristor unit, which consists of a single thyristor or a number in series detects when the current in the thyristor falls below a certain value and generates signals lasting for preset times, the build-up rate of the thyristor voltage is also detected and when this exceeds a preset level in one of the preset times an output signal is generated to fire the thyristor, the preset levels being particular for the associated preset time. A third detector can be used to sense the thyristor voltage. The current may be sensed by a current to voltage converter such as a resistor 8 and passed to a Schmitt type trigger 17 which trips several one-shots 17a, 17b, 17c. The rate of rise of the voltage is sensed by an RC network 2, 3, 4, 9 in parallel with the thyristors and passed to three level detectors 15a, 15b, 15c. The voltage is sensed by a resistive divider 5, 6, 7, 10 and passed to three level detectors 16a, 16b, 16c. The outputs of the level detectors and the oneshots are connected to three AND gates 18, 19, 20 whose outputs are ORed at the input 21a of a trigger generator 21 to retrigger the thyristors. The aim is to detect over-voltages, or trends to over-voltages occurring as the thyristor is commutated off, and by retriggering to prevent the destruction of the thyristor.

Air is supplied to cylinder 22 through a conduit 26, and a duct 27, in slide 16, and the latter is urged to the left, Fig. 2, by springs 28. The upper edge of slide 16 carries two adjustable tappets, which co-operate with micro-switches 32, 33 carried on strips 36, 37, the latter of which is adjustable along the former. In operation, the lathe is arranged for programme operation, and operations are carried out by tools 9, 10. The turret is stopped with the attachment aligned with the work, air passes to cylinder 22 and the tap 19 is moved up to the work. Shortly after commencement of the tapping operation an aperture 20 is uncovered in cylinder 22, thus releasing the air, and the tap is fed by the engagement of the tap with the screwed bore. At the beginning of the operation, switch 33 is released to thus hold the programme control inactive until switch 32 is operated when the required depth of cut has been reached, and the direction of rotation is reversed, so as to unscrew the tap. Springs 28 pull back the tap, and switch 33 is operated, which causes the programme control to make the next steps.

An electric motor driving a cinematograph projector 34 is coupled to cam 31 operating periodic contacts 29, 30, in parallel with resistor 35 which is connected in the motor circuit. A differential gear 36 has crown wheels coupled respectively to the projector motor and to a constantspeed motor which drives a sound reproducer 37. The value of the resistor 35 is such that, when the contacts 29, 30, are open and closed for equal periods, the projector and reproducer are synchronized. If the speed of the projector changes, the movement of the differential cage rotates cam 23 to change the on-off periods of the contacts 29, 30, such as to restore synchronism. A pointer cooperating with a scale indicates the position of the cage so that the projector and reproducer may be brought into the proper phase relationship.
