Title: Improvements in or relating to packing machines
IPC: B65B43/24
Filed: 1937-06-15
Abstract: 492,410. Packeting - machines. STONE, A. A., and MOLINS MACHINE CO., Ltd. June 15, 1937, Nos. 16555, 16556, 16557, and 16558. [Class 94 (i)] Collapsed tubular shells of rectangular crosssection are partially opened, and are then further opened so that the acute angles become obtuse and vice versa and recollapsed in the opposite direction to weaken the creases, so that the shell springs back to a rectangular cross-section when released. A collapsed shell is shown in Fig. 6 and comprises two broad sides 12, 13, two narrow sides 14, 15 and a narrow panel 20 adhering to the side 12 to form a longitudinal seam. In this form the shells are fed longitudinally between two pairs of rollers 24, 25, 26, Fig. 4, so that the raised portions 24 engage the ends 14, 15 and the guide rollers 25 press portions of the broad sides towards cylindrical surfaces 26. This results in the shell assuming the cross-section shown in Fig. 7. A member 27 locates the shell peripherally on the rollers, and continues to move it to a position on a support 30 in the path of a plunger 31 which' moves the partially opened shell to the left so that the side 15 engages a guide 40 pivoted at 41, the corner 18 striking an abutment 42. Combined movement of the plunger exerts diagonal pressure between the points 16, 18, and further opens the shell. The guide 40 is now moved in a clockwise direction about its pivot so as to co-operate with the plunger to cause the shell to have the cross-section shown in Fig. 9. The acute angle at the corner 18 has now become obtuse and the obtuse angle at 17 has become acute. The plunger is formed with two faces, the face 31a engages the corner 16 in the first portion of its stroke, and subsequently the face 31b engages the corner 17. The shell is now moved between rollers 51, 52 which completely collapse it, and, upon release, the resiliency of the material causes it to spring back into a rectangular formation.

Title: Improvements in or relating to engine starters
IPC: F02C7/275
Filed: 1948-06-21
Abstract: 645,635. Turning gear. BENDIX AVIATION CORPORATION. June 21, 1948, No. 16669. Convention date, June 27, 1947 [Class 7(v)] In an engine starter comprising a jaw element 10 adapted to be axially moved into engagement with a jaw member 12 of an engine to be started and to be rotated after its axial movement in order to rotate the jaw member, there is provided inertia means, such as a flywheel part 26; in dynamically balanced association with the jaw element 10 and operative to restrain the element against positive rotative acceleration until the axial movement is effected. An axially-stationary nut 14 is in threaded relationship with the axiallymovable screwshaft 16, the forward end of the screwshaft being spined to the element 10, which latter incorporates the flywheel part 26. The nut 14 is driven through planetary gearing 44 in engagement with an orbital gear 48 connected by an adjustable multi-plate friction clutch 50 to the starter housing as well as a sun gear 46 on the armature shaft 70. A partition 64 in the housing supports a seal 66 and a bearing 68 for the shaft 70. The element 10 is held to the screwshaft 16 by a stud 74 having a flange 76 compressing a seal 78 in a central web of the jaw element, whilst coil spring 85 is compressed between the stud flange 76 and an internal screwshaft flange. The element 10 is provided with a seal 86 engaging an inner extended part of the element, the seal being secured to a casing part 34. When nut 14 is rotated the screwshaft moves leftwardly and due to the inertia of the jaw element the latter does not rotate but is moved axially by the spring 85 into mesh with the member 12, at which time shoulders 90 and 92, on the screwshaft and nut, respectively, come into engagement whereupon the element 10 is then rotated to crank the engine. In a modification, the flywheel part is made integral with the screwshaft, which latter has a splined connection with the jaw element, whilst an oil seal is located in the inner end of the bore of the nut. A retaining nut is also provided on the inner end of the screwshaft so that the latter may be assembled in the driving nut, and the screwshaft has vent spaces therein to prevent a dash-pot action between the driving nut and itself. The jaw element seal may be dispensed with, and a seal located around the driving nut instead. In another modification, the flywheel part and screwshaft are separate, both being splined to the jaw element, whilst a spring is situated between the flywheel part and the jaw element instead of around the stud.

Title: Improvements in and relating to sealing wax
IPC: C09K3/10
Filed: 1924-07-16
Abstract: 220,287. Bornand, E. Aug. 8, 1923, [Convention date]. Seals; sealing-wax; wafers. - Sealing-wax is combined with a solid combustible body composed of an aldehyde, preferably metaldehyde, so arranged that it can be easily ignited. The wax may be in the form of a stick, Fig. 1, having a, core of the combustible material, or in the form of a lozenge, Fig. 3, having the combustible material secured to one face.. In the latter case, grooves may be formed in the wax to receive the combustible material, and a covering of celluloid or other easily-ignited substance may be provided. The wax may be scented, and the lozenge may be made of wax of several colours representing, for example, national colours or heraldic devices. In order to facilitate its application, the metaldehyde may be agglomerated around a core of fibrous or other material. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of a sealing-wax composed of stated proportions of Venetian turpentine, black resin, gum lake, plaster of paris, and cinnabar, and states that the metaldehyde is powdered and mixed with a highly-concentrated solution of black resin in alcohol. The sticks of wax may be formed in two parts, one of which has a groove for the reception of the metaldehyde, the two parts being joined by heating. In another method, the wax may be run into moulds, several of which are placed in line and having an equal number of cores arranged in a single transverse bar adapted to be displaced during the cooling of the wax to prevent sticking. Alternatively the cores may be heated, by electricity or otherwise, after the wax has cooled, to facilitate their removal. The sticks of metaldehyde can be placed in a series of parallel grooves registering with the holes in the sticks of wax, a moving member being employed for forcing them into the wax. The sticks may be provided with one or more cores of metaldehyde, in amount equal to one-tenth to one-twenty-fifth of the stick, placed therein symmetrically or not, and may be provided with a U-shaped handle of wood or other material. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,122,159. Counting aapparatus: selective signalling. ROLLS-ROYCE Ltd. 14 April, 1967, No. 17321/67. Headings G4D and G4H. A histogram, showing the way in which a particular dimension of an article varies over a batch of articles, is obtained by notionally dividing the range in which the dimension is expected to lie unto a number of equal subranges, by measuring the dimension concerned for each article whereby it can be assigned to a particular sub-range, by counting the articles that fall into each sub-range, and by arranging that each counter indicates its total by unmasking a proportional length of a corresponding rectangular coloured strip of a set of strips, one for each counter, arranged adjacent to each other. As described each article 1, Fig. 2, measured 2, 3, causes a pulse to be applied to a corresponding lead 5, the particular lead marked being indicated by lamps 6, 7, and a count is made in a corresponding counter, each of which progressively unmasks strips 12 to provide a histogram. Each counter comprises a transparent endless belt 13a, Fig. 4, carrying a coloured strip 18. Each pulse received firstly energizes a corresponding solenoid to clutch the associated belt against a common driving cylinder 20, and secondly, after a short delay, energizes a rotary solenoid 22 to advance the common driving cylinder one increment. The indicator is so arranged that a photographic plate may be slipped behind the belts to make a permanent record.

Abstract: 1,172,763. Punching. N. DOLBERG. 15 April, 1967, No. ]7408/67. Heading B3W. A machine for multiple side punching a tubular blank supported on a mandrel 38, has blank ejecting device 16 and a plurality of angularly spaced punching units, each including a tool 56 connected to a ram 70 which is radially movable by a connecting cam 78, 80, 82, 84 supported and arcuately moved by a rotatable annular carrier 36 surrounding the punching units. In one embodiment, the machine is operated by a start switch (182), (Fig. 7, not shown), which energizes a solenoid valve (158) to cause extension of a piston-rod 102 which rotates the carrier 36. As the carrier 36 rotates, spherical cam followers 88 mounted on the ends of the rams 70 are moved along elongate slots 86 in the cam elements 78, 80, 82, 84 to cause the rams 70 and punches 56 of each punching unit to be moved radially inwards. The innermost radial position is reached when the rams 70 are perpendicular to the cams, further rotation of the carrier 36 in the same direction causing the rams 70 to move radially outwards to the position of Fig. 6. In this position, a switch 188 is actuated by an actuator 190 on the piston-rod 102 to energize a solenoid valve (168) which causes extension of ejector pins 136 connected to a ram plate 135 of a piston-rod 140, the pins 136 passing through elongate slots in the side wall of the mandrel 38. The ejector pins 136 are returned to their initial position by an actuator 194 closing a switch 192 which actuates the valve (168). When the start switch (182) is again depressed, the punching cycle is repeated with the carrier 36 rotating clockwise. When a greater number of rows of holes or indentations are to be punched, cams half the length of cams 78-84 are used, extension and retraction of the piston-rod 102 performing one complete punching cycle.

Abstract: <PICT:0706085/IV(c)/1> <PICT:0706085/IV(c)/2> A washing process for removing mercerizing caustic from a cloth web whilst the web is protected against shrinkage by being stretched on a tenter frame comprises providing a supply of continuously renewed wash water which is re-circulated through the web at a number of spaced washing stations which are connected independently in parallel to the wash water supply.  Fig. 1 shows a washing process in which the washing water is fed at 13 to a sump 12 from which a supply line 15 feeds a first wash water receiver 17 an overflow outlet from which is connected via a pipe 18 to a second receiver 17 and so via further receivers to a liquid seal vessel 26 which has an out flow pipe 28 which may be connected to the inlet to sump 12.  A given rate of flow of water may be passed through each receiver 17 and water from each receiver is pumped at a pre-determined rate by unit 21 via the heat exchangers 22 to the weir box 10 from which it is sprayed on to the web W which is stretched on a tenter frame and passes continuously under the weir boxes 10.  The water passing through the web is collected by suction boxes 11 and returned to the receivers 17, any air which is collected during the process is extracted by a vacuum pump 23 which is connected in common to all of the receivers 17. Fig. 7 shows the construction of a weir box 90 and the corresponding suction box 95.  Each weir box comprises two oppositely disposed halves each having weir lips 94 and an adjustable dam element 941 which enable the effective width of the weir box to be varied in dependence upon the width of web to be washed.  Similarly the suction boxes 95 are each in two halves, Fig. 9 (not shown), and adjustment of the associated tenter frame width by movement of the tenter frame supports 911 (Fig. 7) under the control of hand wheel 92 results in sliding the halves of the suction boxes on the rail 96 so that their inner ends overlap to a pre-determined extent.  Details of the supply connections to the wash water receivers and heat exchangers are described, Figs. 4 and 6 (not shown).
