Title: Machine for packaging articles into bags
IPC: B65B43/36
Filed: 1963-03-26
Abstract: 983,903. Packaging machines. KOUSEN FABRIEKEN HIN N.V. March 26, 1963 [Oct. 8, 1962; Jan. 7, 1963], No. 11862/63. Heading B8C. Supporting, opening and filling bags.- Articles are delivered into an open-mouthed 155 bag by a pusher 65 (Fig. 2) whose working stroke is momentarily arrested by a latch when the article is substantially completely inserted in the bag and is subsequently released to thrust the filled bag away from the filling location. The pusher 65 is resiliently mounted on a carriage 66 and the latch 71 may either arrest the lever 68 driving the carriage or may arrest the spring-mounted pusher itself, allowing the lever 68 to perform an uninterrupted stroke under the action of a spring 70. The bag is held open by a pair of spring-biased funnel-shaped elements 83 (Fig. 1) which pivot into its mouth and when it is opened by a resilient pressure finger 77 (Fig. 2) and a blast of air from a nozzle 82 and are positively retracted before the filled bag is ejected. The open bag is the topmost one of a pile 72 resting on a tray upwardly biased by a spring arm 86 so that flap-forming extensions 120 (Fig. 4, not shown) on the lower walls of the bag are pressed against a ledge 85a. The arm 86 may be positively lowered when the filled bag is pushed away from the tray, its end edge having been brought horizontally above a Z-shaped ledge 74 by the stiffening effect of the inserted article which may be a pair of stockings folded about a sheet of paper. Operation of the bagopening mechanism is initiated when a microswitch 98 is operated by the passage of a pair of stockings. In an alternative arrangement the tray supporting the bags has vertical pins 102 (Fig. 6) pressing upwardly through registering holes in the bags which are pushed upwardly by the tray against arms 109 swung inwardly about their shafts 110 from the position of Fig. 6 to overlie the bags. After the uppermost bag has been opened the bag-supporting tray and its pins 102 are lowered sufficiently to permit the stockings to be pushed into the bag, and the abutment arms 109 are swung about the shafts 110 to the position shown in Fig. 6 so that pins 112 rigid with them move beneath the filled bag to raise its closed end from the pile. In this construction presser members 115 are moved downwardly to clamp the opened bag against the funnel-shaped arms 83 after these have been pivoted into position to hold the bag open. The bag-supporting tray may be removed from the machine to receive a fresh charge of bags. Closing, sealing and labelling bags.-As the bags are carried between conveying belts 88, 89 (Fig. 1) flaps on them are closed by a fixed plough 92. The flap may then be heat-sealed, or may be closed by a label applied from a roll 94. The labelling device is controlled by a photo-cell detecting the leading edge of the bag and by a second photo-cell detecting the presence of a label ready for attachment to the bag. A warning is given if no label is available for attachment.

Title: A pipe having an inner lining and a method of making such a pipe
IPC: F16L57/06
Filed: 1965-03-19
Abstract: 1,066,203. Casting concrete pipes. WILLIBALD UHL, and FRANZ MOOS. March 19, 1965, No. 11876/65. Heading B5A. [Also in Division F2] A pipe of concrete or cement having a partial or complete lining of synthetic plastic material is made by casting the cement or concrete around a pre-fabricated synthetic plastics lining. The plastics lining is formed by spraying a plastics, such as glass fibre-reinforced polyester resin or soft polyvinyl chloride, on a rotating mould core (6), Figs. 4, 5, 6 and 13 (not shown), the mould core according to Fig. 5 being shaped to form a flange 15 at one end of the lining whereas the core of Fig. 13 is shaped to form a bell-mouthed socket 21 at one end of the lining and a flange 22 at the other. The prefabricated lining is then removed from the core and placed in a mould casing 33, preferably of a two-part construction; Fig. 14 illustrates on the left-hand side of the centre line the formation of pipe having a lining 2 provided with a single end flange, and, on the right-hand side of the centre line, the formation of pipe having a lining 22 provided with a bellmouthed socket. In one case, the lining 2 is stood on a dished mould ring 38 to form a socket in the end of the concrete pipe whereas, in the second case, the lining 22 is supported on a ring 37 and the bell-mouthed socket of the lining constitutes the mould for the pipe end. Concrete is poured between the casing and lining, and a vibratory core 17 set in operation to consolidate the concrete. The lining walls are of varying thickness to ensure keying of the lining to the concrete, and, in order to improve the ability to key, the lining may be additionally sprayed with quartz sand prior to hardening of the plastic as indicated in Fig. 13. The pipe may only be partially lined, as illustrated in Figs. 7, 8 and 9 (not shown), the lining then being manufactured in the form of half shells by providing separation strips 8 on the rotating lining core. The bell-shaped socket of the pipe produced is sealingly coupled to the pipe end or a spigot extension of an adjacent pipe by a ring (25), Figs. 10, 11 and 12 (not shown), which is rolled into position on making the joint.

Title: Improvements in and relating to self-indicating weighing machines
IPC: G01G1/26
Filed: 1926-05-07
Abstract: 270,089. Berkel, C. F. M. van. May 7, 1926. Pendulum - weight apparatus; loose-weight apparatus.-In weighing-apparatus capable of variation in weighing-capacity, the weight adapted to be applied to or removed from the weigh-beam for this purpose, is received by shockabsorbers such as leaf springs. Interlocking-means are provided to prevent simultaneous movement of the capacity-changing means and the weigh-beam. The capacity-varying weight 1 is movable on pins two of which (4 Fig. 3) are carried by the bridge 5 secured to the pan 3 and two (6) are fixed to the base. At the lower and upper ends respectively of these pairs of pins are arranged leaf springs 7, 8 to receive the weight when shifted from one position to the other by a lever 9 pivoted at 33 and connected to a spring-controlled pivoted yoke 15. The lever 9 is also connected by a link 11 to a slide 12 bearing the alternative unit numerals to be read through apertures 13 in the dial. To increase the capacity of the apparatus, a key 26 is depressed to remove a locking-piece 24 from the end 16 of the yoke which may then be depressed by means of a key 18, to lift the weight 1 from the pins 4 and cause the higher units to appear at the apertures 13. During this movement, the end 16 of the yoke wipes over the pivoted locking piece 24 to keep it in engagement with a serrated member 23 secured to the weigh-beam which is thus locked during the movement. When the yoke has been fully depressed the locking piece 24 engages a shoulder 17 to hold the yoke down. In order to change the range back again the key 26 is depressed to rock the piece 24 out of engagement with the shoulder and allow the yoke 15 to rise and the weight 1 to become effective, the yoke then again becoming locked at the shoulder 31. Specification 251,947 is referred to.

Abstract: 1,246,540. Boric oxide and borax composition. UNITED STATES BORAX & CHEMICAL CORP. 6 March, 1969 [30 April, 1968], No. 12047/69. Heading CIA. [Also in Divisions A5 and D1] A boron containing composition consists of (i) particulate boric oxide and (ii) a borax compound selected from anhydrous borax and sodium tetraborate pentahydrate, said boric oxide and borax compound being present in sufficient amounts to provide a Na 2 O : B 2 O 3  molar ratio in the range 0À16: 1 to 0À32: 1, said product having a loose bulk density of greater than 50 pounds per cubic foot. The particle size of the composition is preferably from 40 to 200 mesh (U.S.S.) in order to give suitable handling and solubility characteristics. Also, in order to prevent caking and improve solubility the boric oxide and borax compound particles are of a different mean size: preferably said boric oxide has a larger mean particle size than the said borax compound. The composition has an intended use both as a herbicide and a fire retardent agent and for this reason the level of boron in the composition is at least 20% by weight, preferably 20% to 80%.
Patent GB-1011137-A (GB)
Title: Arrangement for controlling an escape of pressurized fluid from a nuclear reactor
IPC: G21C9/012
Filed: 1963-03-27
Abstract: 1,011,137. Nuclear power plant. WESTING- HOUSE ELECTRIC CORPORATION. March 27, 1963 [April 6, 1962], No. 12051/63. Heading G6C. Escapes of pressurized fluids, such as coolant water, from nuclear reactors are controlled by placing the reactor in a first container from which escaping pressure fluid passes through a pool of liquid in a second container and thence to an expansion volume above the liquid level. A water-cooled nuclear reactor 24 and its associated coolant pipes 22, coolant pumps 18, and heat exchangers 20 are enclosed in an inner pressure vessel 10 of steel or concrete which is itself enclosed within an outer vessel 28. These vessels form part of the reactor's biological shielding. An annular plate 36 sealingly separates the space between the inner and outer vessels to form an upper annular chamber 32 and a lower annular chamber 30. The upper chamber is filled with water to a level 44, and has a series of vertically extending plates within it, the tops 42 of which extend just beyond the liquid level; these plates act as bracing members between the inner and outer vessels. Trunking (not shown) is provided within the chambers 30, 32, which passes through the liquid and the plate 36 to connect the space 60 abbve the water with the space 30. A series of pipes 46 pass from the interior of the inner vessel 10 and are partially submerged in the water 32. The lowermost ends 52 of these pipes are sealed and gas outlets 50 in the form of longitudinal slots are situated entirely below the level of the water. The reactor is stated to be suitable for shipborne use. In operation, when a failure of the reactor primary coolant piping 22 occurs, the high temperature high pressure water therein escapes into the inner chamber 62 and immediately forms steam; the steam, mixed of course with air or whatever other gas was already present in the chamber 62, passes through the pipes 46 and emerges into the water 32. A series of grids 56 help to reduce the size of vapour bubbles as they rise, and all or most of the steam will be condensed in the water. Any remaining gas passes from the chamber 60 through the trunking and finally into the space 30 where it expands until pressure is equalized throughout the system. The amount of radioactive material which might otherwise enter the outer vessel is considerably reduced by the scrubbng inherent in bubbling the gases through the water. Reference has been made by the Comptroller to Specification 936,626.

Title: Improvements in the measurement of the depth of a layer by ultrasonic pulse-echo methods
IPC: G01B17/02
Filed: 1968-03-12
Abstract: 1,211,306. Ultrasonic inspection devices; ultrasonic probes. HITACHI Ltd. and HITACHI METALS Ltd. 12 March, 1968 [20 March, 1967], No. 12062/68. Headings H4D and H4J. In apparatus for measuring the depth of a boundary within a specimen by the ultrasonic pulse-echo method, provision is made for adjusting the magnitude of echo signals reflected to a receiver from the specimen surface independently of the magnitude of boundary echo signals. In an embodiment for measuring the thickness of the outer chilled layer of a cast iron rolling- mill roll 5, a probe is held against the roll while the roll is rotated and echo signals intensitymodulate an oscilloscope time-base which is shifted as a function of the rotational angle, giving a B-scan display of the chilled layer thickness around the roll. The probe comprises transmitting and receiving transducers 11, 12 in a housing 14 containing a water or oil couplant. An acoustic baffle having a fixed portion 131 and a portion 132 which can be moved vertically by screw mechanism 134 defines a slot through which an adjustable fraction of the echo signal S from the roll surface passes to the receiving transducer 12 to provide a clear reference signal for the thickness measurement (even when very thin layers are being measured). Disturbing echoes from graphite flakes in the chilled layer are minimized by using an ultrasonic frequency below 3 MHz, through resolution of the layer boundary decreases with decreasing frequency.

Abstract: 726,604. Stuffing-box substitutes. MORGAN CRUCIBLE CO., Ltd. April 30, 1954 [May 1, 1953; Nov. 2, 1953], Nos. 12195/53 and 30251/53. Class 122 (5). In a sealing device for relatively rotatable coaxial parts, such as a shaft 1 and a housing, in which a sealing ring 2 having a front face to bear against one of the parts is mounted in a cup-like holder 3 adapted to be carried by the other part, the holder is made of resiliently deformable material and has a portion surrounding the periphery of the sealing ring and in key and slot engagement therewith so as to prevent relative rotation whilst permitting relative axial movement and an inwardly extending diaphragm portion in sealing relationship with the rear face of the sealing ring. The sealing ring 2, of carbon, is formed with a number of segmental projections 6 which engage in slots 7, of greater axial extent than the thickness of the projections 6, in a flange 8 of the moulded rubber holder 3, the latter being formed with a diaphragm portion comprising a relatively thin web 9 and a relatively thick inner rim 10 which projects into a recess 11 in the sealing ring and may be adhesively bonded therein. A metal cup 13 fits in a recess in the holder 3 formed by an inwardly directed flange 12 and a compression spring 16, mounted in the cup, presses the rim 10 against the sealing ring. To facilitate entry of the holder 3 in the shaft housing the outer diameter of the cylindrical portion 12<SP>1</SP> is formed with a slight taper to the rear. In a modification the metal cup 13 is omitted and the spring 16 is a tapered spring extending between the rim 10 and the flange 12 and having its large diameter coil, adjacent the flange 12, under radial compression so as to ensure a tight fit of the holder 3 in the shaft housing. When the rim 10 is not adhesively bonded to the sealing ring it may be recessed to provide a "sucker" effect, or the web 9 may be branched to provide an annular flexible sealing lip; also, the flange 8 may be formed with a front wall to retain the sealing ring in the holder. The diaphragm portion may be interlocked with the sealing ring by squeezing a projection on it into a corresponding channel in the rear face of the ring.
