Abstract: 306,124. Ateliers T. Robatel, J. Buffaud et Cie. Feb. 16, 1928, [Convention date]. Strainer separators; casings. - A continuously operating separator with a horizontal shaft has a basket P revolving inside a casing B; the framework A supporting the basket is made independent of the casing so that the parts may be constructed of different metals. The arrangement permits the removal and replacement of the casing without interference with the mechanism. A scraper d to assist in the removal of solid matter is mounted on a rod F bored for the reception of a threaded rod G which is rotated, to operate the scraper, from the main shaft through gearing L. The scraper and its' operating mechanism are carried by the framework A, and the angular position of the scraper can be adjusted by means of the handle K and the worm gear H. The support of the scraper is hinged so that the scraper can be withdrawn from the basket. A friction coupling is included in the operating mechanism for the scraper to allow slipping if the scraper encounters abnormal resistance. In a modification an electromotor is employed to operate the scraper.

Title: Improvements in liquid delivery control apparatus
Inventor: CLARK REX KENNETH
IPC: G05D7/03
Filed: 1960-01-15
Abstract: 908,150. Regulating liquid levels. ESSO RESEARCH & ENGINEERING CO. Oct. 26, 1960 [Jan. 15, 1960], No. 1543/60. Class 123 (1). [Also in Groups XVII and XXV] Apparatus for controlling the delivery of liquid, e.g. petroleum from a bulk source to a tanker 7, comprises a pneumatic main valve 3 located in a delivery pipe 1 which leads to a jointed delivery pipe 4, 5 carrying, adjacent its outlet end, a float 10 which, at a predetermined upper level of liquid, operates a pneumatic switch 17 which indirectly controls the main valve 3 to shut off further supply of petroleum. In operation, the arm 5 of the delivery pipe is secured by a clamp 9 to project through a manhole 8 in the tanker. A push-button 27 on a control unit 26<SP>1</SP> is then pressed which allows compressed-air to impinge upon the lower diaphragm 24 of a pilot valve unit 22 and open a valve port 26 so that compressed-air passes, through a pressure reducing unit 44, to the diaphragm 45 of the main valve 3 and causes the latter to open. The float 10, pivotally attached to a link 12, rises with the liquid until a predetermined liquid level is reached, whereupon the float mechanism opens a port 21 in the switch 17 so that compressed-air passes through a port 33 in a unit 32 to influence the upper diaphragm 23 of the pilot valve unit 22 and open the port 25, the main control valve-air from the pressure-reducing unit 44 being vented off. Simultaneously, the air from the switch 17 is directed, through a port 37 in a control unit 35, to the diaphragm 46 of a valve unit 38 to open a port 39 and release the air pressure from the diaphragm 45 so that the main valve 3 closes. For emergency shut down a stop button 41 is pushed so that compressed-air is delivered in parallel to the control units 35, 32 which actuate respectively the diaphragms 46, 23 of the control unit 38 and the pilot valve unit 22 so that the air pressure is removed from the diaphragm 45 of the main valve 3 which then closes.

Abstract: 872,322. Weighing apparatus. PORTASILO Ltd. Jan. 7, 1960 [Jan. 15, 1959], No. 1553/59. Class 143 Material is fed from a container into a hopper mounted on a counterweighted pivoted beam until the latter, in its balanced condition, automatically closes an outlet valve of the container in apparatus characterised by (a) the point of attachment to the beam of either the hopper, its counterweight or both being above the level of the beam fulcrum at balance and (b) the means by which the outlet valve is held open being disposed wholly above the valve. The beam consists of two bent members 6, one at each side of the hopper 11, each having a horizontal limb which carries the hopper-supporting and fulcrum knife edges 10, 7 respectively with the former higher than the latter. The two members 6 are joined by a rod 13 which extends above the hopper beside the container 1 and which carries a graduated bar 14 holding the sliding counterweight. The container outlet valve comprises a slide 2 (Fig. 3) urged by springs 4 to close the outlet but held open during feed by the engagement of a T-bar 19 carried by a bracket 18 secured to the upper surface of the slide with a roller 20 mounted on one end of a trip lever 21 whose other end is pivoted at 22 to the container 1. The engagement is released to stop the feed when the weigh beam tilts by raising the free end of lever 21. For this purpose the rod 13 of the beam carries a platform 27 (Fig. 1) engaging a roller 26 carried on the underside of a pivoted arm 25 whose free end passes through a hole in the trip lever 21.

Abstract: 792,745. Electrophonic musical instruments. VEB WERK FUR FERNMELDEWESEN. Jan. 20, 1956, No. 1962/56. Class 88 (2). The invention relates to an instrument intended to imitate the sound of a pipe organ, and the Figure shows the equipment for producing the note C and its harmonics. Generators 1-19 produce oscillations rich in harmonics, e.g. sawtooth waves; generators 1-8 are tuned to the fundamental C and its octaves, 9-14 to the corresponding fifths G and 15-19 to the thirds E, and the generators are connected to bus-bars 58-64 corresponding to the various registers (16 ft., 8 ft. and so on) through control networks 20-S7 which determine the attack and characteristic of each register. The sounds required in each register are selected by means of filter networks and formant circuits 66-70, and all the registers called for by the stops being used are added together to form a common output at 84, under the control of key switches 65 and stop switches 80-83. The relative strengths of the different registers are determined by resistances 71-76, and further mixtures may be obtained by means of tappings 76-79 in the filter networks. The generators 9-19 giving fifths and thirds are tuned in just (not tempered) intonation.

[Also in Divisions B3 and C7] Metal e.g. copper, is purified by maintaining a reservoir of molten metal 5 in a hollow electrode 6 partly immersed in the slag 10 of an electroslag casting furnace, discharging molten metal from electrode 6 into the heated slag 10 by means of a plurality of orifices 9 formed in the electrode 6 and submerged in the slag layer, allowing the discharged metal to percolate through the slag and casting the resultant metal. As shown, current is passed between electrode 6 and the growing ingot 13. The casting mould 17 is liquid cooled. Although the orifices 9 are shown in the base 8 of the electrode they could be formed in the bottom of the cylindrical wall. Three hollow electrodes 6 may be immersed in a common slag bath for three-phase operation. As shown, electrolytic copper is melted down under a reducing atmosphere in a furnace 1 from which the melt is passed to the hollow electrode 6 direct or via a tundish 3. Alternatively by making the resistive losses in electrode 6 high, by employing graphite as the electrode, scrap may be melted directly on electrode 6. The electrode may be double walled and water cooled. Alloys are formed by charging the hollow electrode 6 with solid alloying components whereas the remainder is obtained from a preliminary melting furnace.
