Abstract: 516,603. Concentrating ores ; cements. EVERY, C. E. (Smidth & Co. Aktieselskab, F.L.) June 30, 1938, No. 19468. Drawings to Specification. [Class 82 (ii)] [Also in Group V] In a process for separating minerals from suspensions of ores containing slimes a fraction containing the finest particles and having a maximum effective particle size of less than 15 microns is removed from the suspension and the remainder is then subjected to froth flotation. In one form of the process, for example when preparing a raw material for cement manufacture from a limestone, marl, chalk &c., the suspension of the ore may first be deslimed, e.g., by gravity separation with or without a dispersing agent, to separate a fraction containing particles of a size less than about 50 microns, the fraction of a particle size less than 15 microns being then separated from these slimes and the remainder of the slimes concentrated by froth flotation. The concentrate, with or without some of the fine particles of the separated fraction, may be mixed with the original deslimed ore, the latter having been reground and/or further concentrated by flotation if required. The separation of the fraction of less than 15 microns which may, for example, have a maximum effective particle size of about 2 microns, may be effected by centrifugal separation, e.g., by the separators described in Specification 479,872 and 479,891. Specifications 483,822 and 516,601, [both in Group V], also are referred to.

Abstract: 1,090,401. Radar. PLESSEY U.K. Ltd. Aug. 17, 1964 [May 17, 1963], No. 19716/63. Heading H4D. In a radar plan position indicator system a rotating aerial 3 is mechanically coupled through a 1 to 30 step-up gear-box 4 to a synchro generator 5 connected electrically to a synchro motor 7, which is mechanically coupled through a clutch 8 and a 30 to 1 step-down gearbox 9 to the rotatable scan coil 10 of a display cathode-ray tube. The clutch 8 will disengage the drive from the synchro motor 7 to the scan coil 10 when a switch 12 is closed by a cam 11 rotating with the scan coil and energizes an operating solenoid 13 but this will be prevented if a switch 15, closed by a cam 14 rotating with the aerial, short circuits the solenoid. The profile of cam. 11 is such that the switch 12 is maintained closed for sufficient time to stop the rotation of the scan coil and it is also arranged that the return time of solenoid 13 is slightly greater than its operating time. Consequently, should the scan coil rotation become out of alignment with that of the aerial the coil will stop when it reaches a predetermined heading, e.g. North, but will re-start when the aerial next reaches the same heading. Switch 15 may be included in an electronic gating network which effectively opens a switch in series with switch 12 when switch 15 closes. The clutch 8 comprises a dog 19, Fig. 2, slidably mounted on input shaft 16 of the gear-box 9 and movable against the compression of a restoring spring 21 by an armature 13A of the solenoid 13 operating on push rod 20. In the normal position, dog teeth 24 engage a gear 22 meshing with a gear 23 on the synchro motor shaft but when the solenoid 13 is energized, teeth on the other side of the dog engage with a fixed dog 18. The possible operating time is said to be under 10 ms.

Abstract: 247,092. Duhamel, E. C., and Com pagnie GÚnÚrale des Industries Textiles. March 2, 1925, [Convention date]. Density separators; discharging. -A machine for the purification of liquids, more particularly liquids used for washing wools, has a drum a with a solid wall upon which a deposit settles during operation; this deposit is removed by the intermittent operation of a scraper o which can travel in a direction parallel to the wall of the drum without any stoppage of the 'apparatus. The drum is enclosed in a casing d which is provided with a discharge pipe g for the clear liquid. The drum shaft b is driven through a belt and fixed and loose pulleys h, i, or directly by an electric motor. The scraper o is shaped as part of a cylinder and is carried at the end of a rod having a worm engaged by a pinion driven through gearing by the belt pulleys 5, 6. An auxiliary shaft carries pulleys connected by straight and crossed belts to the pulleys 4, 5, 6. When it is desired to remove the deposit the scraper is thrown into engagement by means of a hand-wheel, and the lever r is operated to throw the crossed belt on to the right hand loose pulley 4 and the straight belt on to the pulley 6. The scraper then moves from the open end of the drum towards the closed end. At the end of its travel the pin l<1> displaces the coupling fork and the crossed belt is moved to the fixed pulley 5 and the straight belt to the left hand loose pulley 4. The scraper is then returned to its starting position and the pin l operates the fork to replace both belts on the loose pulleys 4. To assist ready displacement the coupling fork is counterbalanced by weights 10 on pivoted arms, the ends of which enter notches in the fork. The removed deposit is discharged through the outlet y. A steel plate may be arranged at the bottom of the drum so as to permit easy replacement.

Abstract: 499,148. Winches. SLINGSBY & CO., Ltd W., SLINGSBY, W., and SLINGSBY, T. J. L. July 17, 1937, No. 19828. [Class 78 (v)] A winding-drum 3 is freely mounted on a shaft 4 journalled in a casing, and is furnished with a lateral ledge 3a which engages a side of a rectangular nut 2 riding on a screw-thread 4a on the shaft 4. The shaft 4 carries a frictiondisc 7 which bears against a ratchet-wheel 8 loosely fitted on the shaft 4 and engaged by a spring-pressed pawl on the casing. Rotation of the shaft 4 by a handle in the winding- on direction first brings the nut 2 against the drum along the thread 4a till the nut, drum, ratchet-wheel 8 and disc 7 form one unit through friction, and the winding-on then takes place with the pawl riding over the teeth. When the handle is stopped, the load is sustained by the pawl, but should the handle be reversed the nut 2 will leave the drum and, by removing the frictional hold on same, will allow the load to fall with the drum running freely. Specification 407,415 is referred to.
Patent GB-361941-A (GB)
Title: Process for the production of moulded articles resembling wood of compositions containing rubber
IPC: C08J5/02
Filed: 1930-06-30
Abstract: Moulded articles are made by adding to a mixture of latex and sulphur, substances which produce a gradual increase of viscosity, filling the treated latex into moulds, removing the still mobile portion after a short interval, partially coagulating and consolidating the layer adhering to the mould, e.g. by heat or coagulants, removing from the mould, and vulcanizing in steam or under water.  Suitable thickeners are alum, magnesium sulphate, manganese sulphate, calcium formate.  Additions such as vulcanization accelerators, activators, antioxidants, fillers such as sawdust, cork, diatomaceous earth, and colouring matters, may be made to the latex.  The operation of filling, pouring off the liquid, and partially consolidating the layer on the mould, may be repeated to obtain thick or even solid articles.  Before removing the article from the mould it is stuffed with sawdust, asbestos or the like preferably damped if it is a material liable to swell in the presence of water.  The following example is typical:-A mixture of 250cs. of 40 per cent latex, 40 gm. sulphur, 2 gm. piperidine pentamethylene dithiocarbamate, 2 gm. zinc oxide, 0,5 gm. casein, 10 gm. sawdust, and 75 cc. of water, is thickened by stirring with 125 cc., 5 per cent alum solution.  A gypsum mould is filled and left for 5 minutes, whereupon the liquid is poured off leaving a soft coating on the mould.  This is fanned with a Bunsen flame, and the operation is repeated, the cavity is filled with moist sawdust and the article is taken from the mould and vulcanized in steam or under water.  Gypsum moulds are suitable but should preferably be treated before use to remove air adsorbed by the inner wall, and to fill the pores.  The proportion of sulphur to rubber is over 10 per cent, and preferably more than 25 per cent.  Specification 213,886, [Class 70, Indiarubber &c.], is referred to.

Title: Compressive shrinking and finishing machines for fabric webs and improvements thereto
IPC: D06C21/00
Filed: 1955-07-12
Abstract: 785,139. Finishing fabrics. CLUETT, PEABODY & CO., Inc. July 12, 1955 [Aug. 3, 1954], No. 20165/55. Class 42 (1). A machine-for treating a woven fabric web to reduce -the extent to which it will elongate or shrink in subsequent laundering operations comprises means for feeding the web at a predetermined rate, means for progressively shrinking the web compressively, a dryer for the web, means for delivering the web, and means whereby the ratio between the speeds of feeding and delivering the web is indicated to show the amount of lengthwise shrinking. The indicated reading can then be kept at the desired figure by controlling the delivery speed. As shown, Fig. 1, fabric web 2 is fed forward by a drum 12 driven by a motor M. A measuring roller 13 is coupled to a tachometer generator 19 producing a voltage directly proportional to the speed of feed. The fabric then passes through a conditioning unit 15 in which it is moistened, through a bias straightening device 24 and around a heated drum 25 to a clip expander mechanism 31, Fig. 2, which pulls the fabric to a width predetermined by test to be that which the fabric when laundered would normally assume. Thence the fabric is compressively over-shrunk in a rubber belt shrinking machine 32. The drum 34 of machine 32 is heated above 212 F. so that as the fabric leaves the drum much of the water in the web is vaporized quickly. The fabric then travels to a felt belt dryer 49, Fig. 3, whence it passes along either of the two paths shown to a plaiter 65; alternatively, a can-type dryer having heated drums 133-136, Fig. 4, may be used. A second tachometer generator 118 operated from the drive to the dryer drum 50, Fig. 3, or the heated drums 133-136, Fig. 4, produces a voltage directly proportional to the speed at which the web is delivered by the dryer. The two tachometer generators are connected electrically to two coils in an indicating instrument; the two coils influence a pointer so that the latter gives a dial reading proportional to the ratio between the voltages generated by the two generators and hence between the feed and delivery speeds of the web, the dial being calibrated in percentage gain or shrinkage. A motor 77, Fig. 1, drives both the shrinking machine and the dryer, the latter being driven through a variable-speed drive 93 which enables the delivery speed to be controlled so as to give the desired shrinkage reading on the indicator.
