Class 117 A sifter box 10, supported on hangers 40, 42, and reciprocated by a driven eccentric 48 and rod 46 houses screen 24 which divides the box into upper and lower substantially closed chambers 26 and 28, and transverse partitions 68 and 70 located adjacent the feed inlet 30 and outlets 36 and 38 equalise the air pressures above and below the screening surface during reciprocation, and thereby provide an improved flow of stock over the screen. The latter extends longitudinally between imperforate plates 32, 34, and each partition includes a vertically adjustable plate 74 held in position by wing nuts 84. The lower edges of the plates are so located as to allow stock to pass but allows little air to flow from the upper chamber. A further partition 112 may be provided, and the plates 74 may be L-shaped. The sifter box 120 of Figs. 4 and 5 is divided by the screen 160 into upper and lower chambers 162 ,164, and longitudinally extending partitions 204 perforated at 211 and spaced from the sides of the box provide an equalisation of the air pressures above and below the screen during reciprocation. The partitions are secured to the removable top wall 124 of the box and, as shown, the stock supplied through inlet 166 flows along the screen between those partitions thus leaving free the side parts 214 of the screen to allow air communication between the upper and lower chambers as indicated by the arrows. Longitudinally extending pairs of screen support plates 184, 198, also perforated therealong at 216 are provided. In a further modifications the entire width of the screening surface is used for classifying the stock, and perforated longitudinal partitions extend along the sides of the screening surface and are spaced from the side walls of the sifter box and provide air communication between the upper and lower chambers of the sifter box. A number of such sifter units may be superimposed with intermediate imperforate conveying pans, thereby providing pneumatically separate sifting chambers within a single sifter box. Reference has been directed by the Comptroller to Specification 837,037.

Abstract: 738,569. Supply systems for space discharge apparatus. THORN ELECTRICAL INDUSTRIES, Ltd. Aug. 7, 1952 [Aug. 7, 1951], No. 18616/51. Class 38 (4). A hot cathode electric discharge lamp 10 is started by a relay which has a normally open switch 20 in the interconnection between the lamp filaments 12, 17 and a coil 21 which is shunted by a capacitor 24 and is serially connected with another, normally closed, switch 23 of the relay across the lamp discharge current supplying terminals 11, 16; the lamp and relay coil circuit are connected through a ballast impedance, shown as a resistance 14, to circuit input terminals 15, 19 to which a D.C. supply is applied. In starting the capacitor 24 is charged up until its voltage attains the pull-in voltage of the relay, energization of which closes switch 20 to complete the filament heating circuit and opens switch 23 to stop the supply mains energization of the relay coil 21. However, the discharge of capacitor 24 maintains the energization of the relay coil for a period to permit filament heating and on eventual drop-out of the relay switch 20 re-opens to put the full supply voltage across the lamp and a radio interference suppressor capacitor 25 shunted across the switch 20 produces a pulse to assist starting of the lamp. During running the volt drop across the ballast impedance prevents the capacitor 24 recharging to such a value as to pull-in the relay again. The invention is applicable to a plurality of series-connected lamps in which case one switch 20 is provided for each lamp and all such switches operate in sequence. Specification 702,939 is referred to.

Abstract: 596,199. Wrapping - machines. ASPINALL, H. I. July 25, 1945, No. 19013. [Class 94 (i)] [Also in Group VIII] A machine for bundling and cutting into lengths textile or other yarns or filaments comprises, in combination, means for feeding in the required number of ends of yarn, for assembling and forming the ends into an untwisted cable, for applying spirally a wrapping strip to cover the cable and an adhesive strip to secure the coils of the wrapping strip, for drawing the cable at a constant speed past the wrapping means, and applying pressure to achieve effective adhesion, by a pair of endless bands in parallel relation and provided with gripping shoes, and for cutting off uniform determined lengths from the cable. Ends of yarn are drawn from a creel between pairs of rollers a<1>, Fig. 1. The lower roller, not shown, of each pair, is driven and the upper roller is carried on a pivoted lever and rests or is pressed on the lower roller. The yarn ends are formed into a cable by passing through a flared cylinder e, the cable being kept untwisted by a horizontal plate e<1>. The cable then passes through a wrapping section comprising spools f, g, containing adhesive and wrapping strip and carried on a member h, Figs. 1 and 3, which rotates about the axis of the cable, whereby the strips are laid helically on the cable, the adhesive strip being laid first with its adhesive side outermost. The wrapped cable passes through a tubular boss h' of the member to the forwarding means, which comprises endless chains h<3>, h<4> in parallel relationship and carrygripping shoes h<5> having semi-cylindrical inner faces which engage the cable and draw it through the apparatus without slip, and also exert pressure on the wrapping strip to achieve effective adhesion. From the forwarding means the cable passes through a tubular support h<2> to the cutting-off section where it is cut into lengths (see Group VIII), the cut-off portions passing down a chute t to a receiving receptacle.
