Title: Phase failure-and null current-detector especially for an electronic motor protection relay possessing current-dependent triggering
IPC: H02H3/13
Filed: 1975-09-09
Abstract: 1525475 Fault detecting arrangements SPRECHER & SCHUH AG 9 Sept 1975 [1 Oct 1974] 37091/75 Heading H2K  A comparator arrangement O 1 , O 2  responds to both the mean and instantaneous values of a signal U m  representing the currents in a polyphase line to provide on a first line 1 a first signal when the currents become unbalanced (signifying phase failure) and on a second line 2 a second signal when the currents drop below a predetermined level.  The arrangement may be used with the temperature simulating arrangement shown in Fig. 3 of Specification 1,423,748. In this case the second ("no-current") signal is used to maintain an input to the clock-frequencydetermining integrator-e.g. via the forwardbiased gate of T 1 -even though U m  has collapsed. The first ("phase failure") signal may be used to switch on T 1  so as to reduce the input resistance of the integrator and thus increase the rate of charging of the simulating network to correspond to the phase-failure condition.

Title: Device for sorting elongated cylindrical objects
IPC: B07C5/06
Filed: 1956-12-06
Abstract: 849,822. Sorting solid materials. FITZGERALD, A. S. Dec. 6, 1956 [Dec. 6, 1955], No. 37347/56. Class 117 [Also in Groups XIX and XXX] A device for sorting cylindrical objects in accordance with their diameters comprises a gauge member 31 provided with an elongated recess 32, the opposing faces of the recess being spaced apart at one zone by a distance greater than the diameter of the largest object to be sorted and the distance between these faces diminishing progressively, means for causing an object to be sorted to roll along the recess until stopped by reason of the diminishing distance, and means for discharging the object into one of a number of compartments 8 disposed side-by-side along the recess. A drill or other cylindrical object to be sorted is placed in a hopper 44, which allows it to fall substantially along the line of greatest slope on to a non-magnetic plate 19, Fig. 2, in the recess 32 formed between the plate 19 and a plate 31 spaced apart by flanges 5a, 5b of the base plate 5. The drill is then made to move along the recess 32 by magnets 29 in a carriage 24 running on a track 22 below the plate 19, and when the drill reaches the point where the width of the recess 32 is less than its diameter its rolling movement stops, and it slides into the correct section of a rack 8. Operation of the mechanism can be either manual, on pressing a button 60, or automatic, whenever a drill drops from the hopper 44, a circuit diagram, Fig. 4 (not shown) being described. A motor (also not shown) drives through reduction gearing a shaft 34 driving a crank arm 36, which reciprocates the carriage 24 through two pin and slot mechanisms 37, 38; 27, 28, and an intermediate lever 23. Whether manually or automatically operated, the carriage makes one complete return journey each time the motor is energized, and finishes in the position shown in Fig. 2 in which it is ready to receive another drill for sorting. A switch 42, the button 60, and a contact device at the foot of the hopper are in parallel with one another and in series with the motor. Thus operation of the button 60, or of the contact device, momentarily energizes the motor, and the arm 36 is displaced from the switch 42, thus closing it and so allowing the motor to continue to rotate until the switch 42 is again opened. A switch 41 is provided in order to energize momentarily an electromagnetic impact or vibrator device which taps the sorter when the carriage is at the right-hand end, in order to free any drills which may have become stuck under a step of the recess 32. In order to shorten the length of the sorter, the track 22 is inclined, so that the magnetic force at the smaller end of recess 32 is considerably less than at the other end. The sorter may be used to sort objects which are not entirely cylindrical, providing they have a cylindrical portion.

The knob 6 is of insulating material and is provided at its inner end with a metal annular bush 9, which is rotatably mounted in a hole in the arm 8 and is formed with a V- groove or a conical shoulder 15 which frictionally engages a peripheral conical portion 14 of a disc 10 secured to the spindle 2. A lever 18 is pivoted at 21, Fig. 4, on the inner side of the part 8 of the bracket 5 and has a part circular chamfered recess which engages the shoulder 15 so as to prevent axial movement of the knob 6. A spring 23 normally presses the lever 18 into the groove in the bush 9 and, owing to there being some play between the bush and the hole in which it works, presses the shoulder 15 into contact with the periphery 14 of the disc 10. The conical edge 14 of the disc 10 is cut away at one point so as to permit removal of the knob 6 when this point is brought opposite the knob and the lever 18 is pulled aside. The spindle 2 carries a drum 25 bearing a scale. 26 which is observed through an opening 27 in the knob 6, as described in Specification 326,800. The lever 18 carries a small pointer 28 which co-operates with the scale 26. The bracket 5 may be fastened to the back of a panel by bolts &c., or may be provided with feet for fixing to a baseboard.

Open-pan sintering-apparatus.-A grate, particularly for use in ore-sintering pans, has barcarrying frames, which are rocked, when the pan is tilted for dumping, to move some bars in one direction and others in a different direction. The pan is stiffened transversely by beams 5 which serve to support the frames 19 which are carried by pins 21 journaled in brackets 13 secured to the beams, each row of frames extending transversely of the pan. The grate-bars extend transversely of the frames, the end bars 31, 33 resting in recesses in the wall of the pan. The intermediate bars 32 have lugs 42, 48 at one end and a lug 42<1> at the other end. The lug 42<1> and the flange 46 of a frame. are located in the recess between the lugs 42, 48 of the next bar in the line. The bars in the next line are arranged in the opposite way so that the adjacent ends of bars are engaged by the other flange 46 of the frames. Each line of bars has a long end bar 31 and a short end bar 33 having a recess engaged by the end frame and adjacent bar. An arm 26 on each frame engages a heavy slotted bar 28 which slides in guides 29 when the pan tilts and causes the frames to rock. Since one flange of each frame will be raised and the other lowered, alternate lines of bars will be raised and lowered. The end bars will be tilted alternately upwards and downwards. A modified form of sliding bar 65, Fig. 23, has inclined faces 69, 71 which engage inclined faces on the guides 66 to prevent premature movement of the bar in either the normal or inverted positions of the pan

Title: Improvements in or relating to the production of oxygen-evolving preparations suitable for use in respiratory apparatus
Filed: 1930-12-17
Abstract: Oxygen evolving materials for use in respiratory apparatus are prepared by submitting hydrates of alkali peroxides, prepared by heating mixtures of the peroxides with substances containing water of crystallization to pressures exceeding 50 kilograms, preferably 350 to 400 per square centimetre.  The water may be in the proportion of one third to one molecule for each molecule of peroxide and the pressure may be applied before, during or after the heating stage. In one manner of carrying the invention into effect, the finely divided substance containing water of crystallization is mixed with dry, finely divided sodium peroxide, the mixture is heated and the resulting material is reduced to grains of 1 millimetre or less, after which it is sieved and compressed at 350 to 400 kilograms per square centimetre.  The siftings may be briquetted alone or mixed with similar granular material, or the sieving may be dispensed with and the ground mass directly briquetted.  When the peroxide mixture is briquetted prior to heating, lower pressures, e.g. 150 to 200 kilograms, may be employed.  Hydrated peroxide prepared in any other manner, e.g. by hydration with finely divided water, may be employed and known catalysts, e.g. oxides and salts of copper, nickel, cobalt and manganese, may be added.  Specifications 138,649, 280,554, 305,101, and 319,393, [all in Class 90, Non-metallic elements], are referred to.

The device has the V 1  characteristic illustrated (though it is stated that under special circuit conditions the breakdown characteristic of known devices is exhibited-Fig. 1, not shown) and it is stated that V B  falls with increasing temperature. If the device, operating at room temperature and in conduction at V 1 ,I 1  has its temperature raised it remains conductive until a temperature T 2  is reached when it becomes non-conductive (and continues so with still higher temperatures) and remains non-conductive until the temperature is lowered to a temperature T 1  (above room temperature) when it reverts to conduction at V 1 ,I 1  Thus the device may be used as a thermally controlled memory unit. The individual devices of a matrix of such units may be controlled by a scanning laser beam. (The optical reflectivity of the insulating layer changes with the state of the devicethis property may be utilized).
