Title: Improvements in apparatus for the feeding of powder and like fluent materials
Inventor: ROSE ALFRED GERMAN
IPC: B65B1/44
Filed: 1954-05-21
Abstract: 787,179. Radiation indicating-systems. ROSE BROS. (GAINSBOROUGH), Ltd. May 19, 1955 [May 21, 1954], No. 14945/54. Class 40 (3). [Also in Groups XXXV and XXXVIII] In a carton-filling machine (see Group XXXV) of the type in which telescope hoppers feeding the cartons have their capacity adjustable as a result of check weighing in order to keep a constant weight of carton charge, an absorbing wedge 139, carried by an arm movable with the weigh-beam of the check-weighing apparatus, varies the intensity of the radiation received from a radio-active source 141 by an ionization chamber detector 142 if the test charge deviates from a required weight corresponding to a desired charge weight, results in the energization of a reversible motor which adjusts the hopper capacities in a corrective sense. A reversible motor is thereby energized to adjust the hopper capacities in a corrective sense and to initiate a follow-up movement of an arm carrying the radiation source and detector, so that the motor is de-energized when the arm and wedge are again in the relative position corresponding to a datum radiation intensity representing the desired weight. The capacity adjustment is thus proportional to the weight deviation of the test charge. A proportional adjustment may be obtained without the follow-up device by means of the arrangement of Fig. 6. The intensity of radiation passed by a wedge 172 movable with the weighbeam is compared with that passed by a fixed reference wedge 173, the two wedges being associated with respective sources 162, 171 and detectors 167, 168. The latter are oppositely charged so that an amplifier 174 receives a net signal current from the detectors representing the deviation of the weight from a required value set by screw adjustment of the wedge 173. The output of the amplifier is applied to relay mechanism 176 for actuating the capacity-adjusting motor and to a condenser 177 whose charge, dependent on the weight deviation, determines the time for which the motor runs and hence the amount of adjustment. Completely-absorbing screens may replace the wedges, whereby the variation in intensity received by the detector is effected by the partial covering of the source outlets. Specifications 686,906 and 781,180, [both in Group XXXV], are referred to.

Filed: 1978-04-18
Abstract: A briquetting plant for hot briquetting particulate matter, such as mill waste containing a material that softens when heated, such as iron oxide, which includes a low temperature tumbler type heat exchanger, an intermediate temperature tumbler type heat exchanger, a fluid bed furnace and a compactor, with the feed material being fed therethrough in succession. The briquettes produced by the compactor are first fed from the outlet of the compactor into the intermediate temperature heat exchanger, for liberation of heat therein, separated from the feed material by a screen at the outlet of the intermediate temperature heat exchanger and from such screen transported into the low temperature heat exchanger for further imparting of heat to the feed material. A second screen is provided at the outlet of the low temperature heat exchanger for separating and discharging the briquettes in relatively cooled form. The tumbler type heat exchangers are in the form of a hollow cone having a wide included angle enclosed by a cover and slowly rotated about an inclined axis to provide intimate mixing of the components and uniform withdrawal of the mixture. The heat exchangers are mounted at a low level and the screens are mounted at a high level with bucket type elevators in between and with the furnace and compactor being located at successive intermediate levels so that, except for the two bucket elevators, all of the flow in the plant takes place under action of gravity. Wet and dry feed materials are separately handled, with means being provided for conveying the dry feed directly to the second heat exchanger.

The cords of the adjacent cross-plies 34, 36 are indexed at substantially equal but opposite angles to the mid-circumferential plane, wherein said acute angle is between 25 and 45 degrees. The inner and outer tyre members are joined together around the bead portions 12. A valve member 11 extends through one of the sidewalls 16 of the outer tyre member and into the outer chamber 25. Chafer strips are incorporated in the region of the plies 24, 26 receiving valve 11 to reinforce the radial ply 24. The dual chambered tyre may be manufactured by placing component parts of the inner tyre member on a cylindrical drum 40, covering said inner tyre member except for the annular marginal edges thereof with an adhesion preventing substance, and placing all components except the belt 15 and tread 14 of the outer tyre components on top of the inner tyre components. Circular inextensible bead rings 13 are disposed at the ends of the drum against the marginal layer of the assembly. The marginal edges are turned over said bead rings to tie-in the carcasses to the bead. The sidewalls 16 are secured to the outer tyre member, and the outer tyre member is inflated to separate adjacent parts of inner and outer tyre members. The whole tyre assembly, so far described, is then expanded to have toroidal form so that the outer member may engage the belt 15 and tread 14. The uncured tyre is then cured in a mold employing the outer chamber, which is lined with strong liner material capable of withstanding high temperatures of curing media such as steam, as a curing bladder for shaping the inner tyre member 30. The different expansion characteristics of the outer radial carcass and inner cross-ply carcass cause a dual chambered tyre 10 to be formed by the method hereinbefore described. The cords 18, 28, 38 may be manufactured from rayon, nylon, polyester, glass, steel or a mixture thereof, and the adhesion preventing material from zinc stearate, non-adhering butyl current, talc, paper or Holland cloth.

Abstract: 1,100,845. Centrifugal separators. BABCOCK & WILCOX CO. 12 April, 1965 [17 April, 1964], No. 15493/65. Heading B2P. [Also in Division F4] A centrifugal separator 32 mounted in the steam and water drum 10 of a steam generator comprises a tangential inlet duct 44 leading a mixture of steam and liquid into the whirl chamber 34 of the separator, Fig. 4, an outlet 42 (in each end wall of the chamber) for discharging separated steam from the central space of the chamber, and a water outlet duct 48 communicating with the interior of the whirl chamber through apertures 50 in a part of the peripheral wall of the chamber. A number of separators (32), Figs. 2 and 3 (not shown), are horizontally mounted in two rows in the steam space (12) of the drum. Feed water entering the water space 14 through a perforated pipe 16 flows downwardly through downcomer tubes (18). Steam and water mixtures pass through riser tubes 20 and enter a watertight compartment 22 extending longitudinally of the drum. The inlet ducts 44 are of rectangular cross-section, each having its lower, inlet end opening to and forming a part of the compartment 22 and its upper, discharge end opening tangentially into the corresponding separator chamber 34. Immediate downward movement of the steam discharging from each outlet aperture 42 is prevented by a U-shaped guiding device 54 secured between each pair of adjacent separators and leading the separated steam upwardly through inclined perforated plates 64 extending along the length of the drum above rows of separators and serving to remove a portion of the moisture still present in the steam. Final removal of moisture from the steam before it leaves the drum through an outlet 70 is by means of a scrubber 68. In operation, the flow of separated water from each separator through the apertures 50 is such that a water layer or film is always maintained over the whole of the water outlet whereby the steam in the central space of the separator can never flow via the outlet duct 48 into the water space 14.

Abstract: 185,719. Soc. Anon, L. Brandt et FrÞre, (trading as Omega Watch Co.). Sept. 8, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Winding-indicators.-A mechanism for indicating the degree of winding of the mainspring in a clock-work device comprises a nut 1 working on a threaded part of the barrel arbor 2, and a pin 4 fixed to the barrel 3 and operating in an aperture in the nut 1. During winding the barrel arbor 2 is rotated by the winding-mechanism and the nut 1 is moved along the arbor. When the main spring is released, the barrel 3 rotates and, driven by the pin 4, the nut 1 is rotated and unscrewed along the arbor 2. These displacements of the nut 1 are used to indicate the degree of winding of the mainspring by means of various index-operating arrangements. In the form shown in Figs. 1 and 2, the nut 1 is provided with a collar 5 which co-operates with the forked end of a lever 6 pivoted at 7, which lever, by means of a finger 8 acting in a helicoidal groove 9, turns a spindle 10 provided with an index 11. In a modification, a circumferential groove cut in the nut 1 and a co-operating finger on the end of the lever 6 actuate the, index; while a further modification consists in forming the nut 1 with an inclined side and spring-pressing one end of a lever against the side of the nut. The other end of the lever carries a rack which gears with a pinion on the indicator spindle.
