Title: Improvements in collecting pallets
IPC: B65D88/12
Filed: 1966-05-03
Abstract: 1,081,278. Load handling pallets. BROMMA SMIDES OCH MEKANISKA VERKSTAD A.B. May 3, 1966 [May 4, 1965; Oct. 1, 1965], No. 19352/66. Heading B8H. A collecting pallet for carrying a plurality of load pallets comprises a main rectangular frame 1 assembled of three channel-section longitudinal beams 11 and a number of channel-section transverse beams 12. Support bars 2, 3 are mounted on the beams 11 to prevent transverse displacement of a load. Longitudinal displacement of a load is prevented by detachable pillars (16), Fig. 4 (not shown) fitted into sockets 10. Standard load pallets are indicated in the lower half of Fig. 1 by chain - dotted lines. Removable longitudinal and transverse top bars (17) form a housing frame structure for a tarpaulin or like cover. The lower surface of the pallet is closed by a metal mesh protective net 19 forming the bottom of a storage space which can be utilized for storing the cover, pillars (16) and top bars (17) when not in use. On each side of the transverse central plane through the frame 1 an adit (6), Fig. 3 (not shown), is provided between two transverse beams 12 for use in connection with a lift fork. In most cases the pallet is lifted by a straddle truck. Corner boxes (8) with holes (9) are provided for the lifting hooks of a crane yoke or the like are mounted in the corners of the frame 1 below the load surface. By placing a plurality of standard load pallets to form a floor (if such is not provided) in the frame 1 the collecting pallet can be used for shipping goods which are not adapted for standard pallet loading.

Abstract: 851,134. Packages. HESSER MASCHINENFABRIK A.G., F. June 19, 1958 [Oct. 18, 1957(2)], No. 19595/58. Classes 94(1) and 94(2). A flat bag package, particularly for liquids, has a protective cover 2 connected to the mouth and to the lateral margins only of the bag 1 and allows a certain amount of relative movement of the bag within the cover. More than one bag may be shielded by a single cover. The bag and cover may both be of polyethylene, the cover preferably being stiffer than the bag, or may be of foil coated with a heat sealable coating. The cover may be of cardboard or metal foil or strips of these materials may be placed between the bag and cover and be printed to indicate the contents or origin. An edge of the cover may be stiffened by a flange 9, Fig. 3. The bag may have a duct 85, Fig. 3b, in a sealed corner 83 the duct being cut through at 86 when the bag is opened. In another form the bag tapers upwards. Two rows of bags may be formed simultaneously by leading a tube of foil 11, Fig. 4, over a former 14, applying to each side two strips 15, 16 and 17, 18 laid sideby-side with a gap 37 between them, Figs. 4, 5. Seals 24, 25 are formed by wheels 26, 27, 28, 29 and cutters 30, 31 remove the top exposed surface of the tube 11. Transverse seams 36 are formed subsequently. An alternative method of production comprises folding a tube 11 to the form shown in Fig. 7a, forming transverse seams thereacross to form the bags, cutting away the outermost layer at 45 and passing the tube over a former 47, Fig. 8, so that the open mouthed bags are presented for filling. Wheels 49, 50 subsequently seal the bags. In a further method, Figs. 11 and 13, a strip 61 is folded longitudinally and strips 64, 65 are laid on each side thereof, wheels 66, 67 form a seam 68 and a nozzle 71 fills each bag. Jaws 73, 74 form transverse seams. In a modification of this method, a single strip is folded to W form.

The shaft 7, in a sleevebearing 41 attached at one end to a gear-box 45, is guided for vertical movement in the machineframe 3 by slideways 68 engaged by a flange 43 on the bearing 41. The cutter-shaft 2 and a worm-shaft 57, which is slidable with the gearbox 45, are driven from a motor through beltgearing 53, 56, the worm-shaft driving the shaft 7 through two worm-gears 58, 59, 61, 62. A clamp 5 of the kind described in Specification 812,693 is carried at the top of the head 6, and the follower is supported by a bar 25 adjustable in the head by a screw 27 co-operating with a detent 26 engaging a notch in the bar. Nuts 29 secure the bar after adjustment, and furtheradjustment may be effected by changing the cam 9. Part 34 of the clutch is integral with the head and is engaged with the other part 35 of the clutch by turning a handle 37. A microswitch (not shown), operated by the flat, stops the driving-motor at the end of the operative swing of the head 6.

Abstract: 1385368 Nitration process SANDOZ Ltd 27 April 1972 [30 April 1971] 19620/72 Heading C2C A nitration process using concentrated HNO 3  is characterized by adding dilute HNO 3  to reduce the rate of reaction, the amounts of concentrated and dilute HNO 3  used being such that the HNO 3  concentration of the residual acid solution is greater than at the azeotropic point of said solution, the residual acid solution subsequently being fractionated into a concentrated HNO 3  fraction and a dilute HNO 3  fraction. The process is preferably effected continuously with the concentrated and dilute HNO 3  fractions being recycled. Water produced during the reaction may be removed as dilute HNO 3  and supplementary amounts of concentrated HNO 3  may be added to the concentrated HNO 3  cycle. Preferably, the concentrated HNO 3  is at least 90%, the dilute HNO 3  has a concentration of 70 to 80% and the HNO 3  concentration of the residual acid solution is 75 to 90%. In the examples, anthraquinone is nitrated to form mainly mononitroanthraquinones together with a minor amount of dinitroanthraquinones.

The tobacco stream 6 is formed and trimmed in known manner on a suction backed porous conveyer band 4 from which it is transferred to the wheel 14 where it is held by suction. A rotary knife 92 cuts the stream 6 between each segment 14A-E and the segments downstream of the knife 92 are accelerated to space them before the tobacco sections thereon are deposited on a transfer wheel 18 between spaced double length filter sections 20. The acceleration (and subsequent deceleration) of the segments 14A-F is effected by a cam actuated bell. crank mechanism. A cam actuated knife (66), Fig. 2 (not shown), carried at the trailing end of each segment 14A-E, supplements or replaces the knife 92 and additionally serves as an end wall for the separated tobacco section until its transfer to the wheel 18.

The pressures above and below diaphragms 3 and 4 (which are selected to give equal pressure drops at the desired flow ratio) are communicated to chambers 6-9 so that the net force on earthed framework 22, 23 attached to diaphragms 18-21 is zero at the desired ratio, and otherwise it energizes one of the relay coils 30, 31 to switch the motor 34 over 32 or 33. Chamber 24 is filled with a viscous non-conductive liquid such as silicone oil; the damping effect may be increased by providing an apertured partition 24a. Modified diaphragm arrangements in which the chambers 6-9 are in tandem and in coaxial pairs are described and illustrated ; the chambers may contain hollow cylinders to reduce acceleration effects.
