Title: Improvements in machines for separating nails, stones and other articles from tea, coffee, and other substances
IPC: B07B13/00
Filed: 1920-11-04
Abstract: 174,231. Banks, G., and Gemmell, F. J. Nov. 4, 1920. Pneumatic separating; reciprocating sieves.-Relates to machines for separating nails, stones, &c. from tea, coffee, &c. and embodies separating devices of the type in which the materials pass down an inclined surface 4 formed with a gap from which air issues at a pressure sufficient to support or blow away the lighter constituents while allowing the heavier constituents to fall through. A hood 14 communicating by a suction pipe with the blower 10 is disposed above the gap 5, and a filter 9 is provided in the delivery pipe from the blower to the gap 5 to extract the dust from the air. The surface 4 below the gap 5 is formed as a coarse sieve through which the tea &c. passes to an inclined fine sieve 21. Constituents which are too large to pass through the gap escape by an aperture 18, baffles 16, 17 being provided to prevent the tea &c. from being blown through this aperture. The hood is fitted with a sieve 15 to prevent the passage of materials other than fine dust with the air. The materials passing through the gap 5 pass down shoots 19 to shoots 20 discharging at the sides of the machine. The surface 4, the baffles 16, 17, the shoots 19, 20, and the sieve 21 are carried by a box 13 which is reciprocated horizontally from an eccentric 24.

Abstract: 1,270,017. Film-feed mechanisms. HIRAOKA KOGYO K.K. June 20, 1969 [Nov. 21, 1968], No.31422/69. Heading G2E. In a cine projector using wide film such as 70 mm film movement during the intermittent pauses at the projection gate is prevented by the provision of a movable film-guide 2 which resiliently presses film 3 against a fixed filmguide 1 with convexly curved surface 31 during the pauses. Film guide 2 comprises a resilient plate 19 secured to a frame 22 mounted on the gate frame 21, and adjustably secured to a bracket 26. The intermittent movement of plate 1 in synchronism with intermittent drive of sprocket 6 is provided by the engagement of rotating cam 18 with the plate. In an embodiment, the fixed guide is concave and the non-resilient movable guide slides on two guide bars against spring-loading under a cam drive.

Title: Improvements in or relating to liquids measuring apparatus
IPC: G01W1/14
Filed: 1949-12-08
Abstract: 679,381. Measuring rate of fluid flow; rain gauges. LEA RECORDER CO., Ltd., and GRESTY, E. Dec. 8, 1950 [Dec. 8, 1949], No. 31490/49. Classes 97 (ii) and 97 (iii). A gauge for the measurement of the rate of flow of a liquid comprises a container 4 to which the liquid is fed as through a stationary pipe 1 having apertures 3 in its side to dissipate the momentum of the liquid before entering the container 4, which is movable against a restoring force relatively to a fixed tapered needle 2 co-operating with an orifice 5 in the bottom of the container so as by the relative movement to vary the opening of the orifice until the inflow to the container is equal to the outflow therefrom through the orifice 5. As shown, the container 4 is mounted by means of a knife edge 6 on one end of a beam 7 pivoted on knife edges 8 and subjected at the other end to a restoring spring 9. The beam is provided with a scriber arm 10 for making a record mark on a clock-work driven chart. Alternatively the container 4 may be carried on knife-edges from a gimbal ring itself carried by a pair of knife edges from the beam, the two pairs of knife edges being at right angles to each other. The beam 7 may be supported by a ball-and-socket joint coupled with a knife edge to prevent movement along the knife edge. When used as a gauge for measuring the intensity of rainfall, the rain is collected over a given area, e.g. by a main funnel in accordance with accepted principles and then preferably passed through a filter funnel to the pipe 1 for delivering to the container 4 which may taper internally towards the orifice. The movements of the beam 7 may be transmitted electrically by known methods, to a remote recorder.

Abstract: 387,442. Cigarette cases. PARKER PEN CO., Court Street, Janesville, Wisconsin, U.S.A. Nov. 16, 1931, No. 31719. Con- .vention date, April 17. [Class 18.] A mounting for a cigarette case &c. comprises a tubular member to which the case is attached, and the wall of which is provided with a plurality of slits so as to become yieldable and to engage frictionally the wall of an opening in a base over a substantial portion of the axial length of the wall, to maintain the article in position on the base. As shown, a pen-support 10, Fig. 2, is mounted on the base member 17 by the slit sleeve 12 which fits in a socket 18 and is formed with projections 22 which resiliently engage beneath a shoulder 38 formed on the socket, so that the sleeve 12 can be withdrawn by an axial pull. Projections 19 limit the extent to which the sleeve can be inserted. The support 10 is mounted on a ball 11 fitting in a socket 14 and held in adjusted position by a spring 15. A recess 23 in the socket 14 permits the support 10 to be turned down to a substantially horizontal position, and the support with its attached sleeve is rotatable relatively to the base 17, thus providing a universal mounting for the support. In a modification, Fig. 8, the support is attached to a ball 41 mounted in a socket 40 and held in position by a spring 45, which is held between a washer 44 and the inturned ends 53 of spring fingers 46a of a sleeve 46, which is attached to the socket by crimping its edge 40a over the out-turned fingers 46b of the sleeve. Alternatively, the ball 41 and spring 45 may be omitted and the spring fingers 46a rendered more resilient by means of a split ring inserted in the inturned ends 53 of the spring fingers, these ends being bent as shown to form projections which engage the shoulder 38 of the socket 18, Fig. 2 ; the socket 40 is replaced by a disc-shaped attachment member secured in a similar manner and provided with a screw, on which may be mounted the cigarette case &c.

Abstract: 1349909 Coiling; making heat exchangers; shearing GENERAL ELECTRIC CO 8 July 1971 [13 July 1970] 32152/71 Headings B3E B3A and B3W In a method of simultaneously winding two metal strips 16, 17, Fig. 9, onto a tube the strips are fed to two diametrically opposite rolls 18 of a winding head 10 from a coil 141 consisting of the two strips wound in an interleaved double spiral. In operation the coil 141 is rotated by a table 14 at a faster rate than the winding head so that at the start of the winding operation an inner coil B is built up around the winding head. The building up of the coil B continues until approximately one half of the strips have been removed from the inside diameter of the coil 141, whereafter the thickness of the coil B begins to decrease. After passing guide rolls 18 the two strips are guided by guides 19, Fig. 1, rolls 21, 22 and guides 23 to their respective lancing stations 24. The lancing stations, Fig. 4, impart cuts to each strip, the cuts extending in from adjacent opposite edges (Fig. 4a) and the cutting being effected by a drive roll 31 and idle rolls 32, 33. The lanced strips 16a, 17a pass to forming stations 26, Fig. 5, where each is engaged by a drive roll 40 and is carried in a groove 46 of the roll 40 until it engages an idler roll 42. At this point the lanced strip is bent into a U-shaped configuration. The strips 16b, 17b then pass to hemming stations 27, Fig. 6A, where each U-shaped strip engages a roll 58 at a point ahead of rolls 57, 59, 61. As the strip is carried through the nip of the four rolls, the strip is deformed to provide a hemmed base 91 having diverging fins. Finally the hemmed strips 16c, 17c pass around guide rolls 28 and are wound on to the tube 12 to produce the finned tube shown in Fig. 7. If the materials of the tube and strips are different, e.g. aluminium and iron, the tube is first coated with a dielectric adhesive layer 130 to prevent galvanic action.
