Title: Improvements in packets or containers for powders or other commodities and in the means for and method of producing and filling same
IPC: B65B7/16
Filed: 1933-12-04
Abstract: 429,927. Wrapping-machines. LOWE, R. G., 11, Charnwood Road, Loughborough, Leicestershire. Dec. 4, 1933, No. 34087. [Class 94 (i)] Packets of powders and the like are formed by perforating a strip of cardboard or like material which is closed at the top and bottom by sheet material, the strip being severed at intervals to form the individual packets. The sheet material is provided with an extension by means of which the packet may be opened. As shown in Fig. 2, a strip 10 of cardboard &c. is advanced to a position at which an aperture 51 is punched therein, and a web of paper 41 is adhered to the bottom. A block 100 is formed by severance between the apertures, and the cavity is filled with powder &c. Finally a strip 81 is applied to the top and is severed between the blocks, a margin 96 being allowed to project to form a tab to facilitate removal. The punch 14, Fig. 3, is operated by an arm 15 pivoted at 16 and returned to the inoperative position by a spring 17. The strip is fed forward in guides 12 by a crank-operated connecting rod 31, Fig. 4, carrying a feed plate 32 on which are mounted arms 33, 34 the ends 35, 36 of which are formed to engage the front walls of apertures during a forward stroke, and to ride over the transverse partitions during the return stroke. The web 41 of paper, which is coated with thermo-plastic adhesive, is applied to the underside of the strip 10 to close the lower mouth of each cavity, and is drawn from the reel over an electrically-heated iron to soften the adhesive, an intermittently operated pressure ensuring adhesion. Alternatively, gum may be applied to the strip 10 or to the web 41. The strip is now severed between the apertures to form a series of rectangular cases which are propelled through a filling station comprising a horizontal cylindrical filling drum 65, Fig. 7. The drum is continuously rotated to raise the powder by means of vanes 69, and to cause it to fall into the apertures 51. A scraper 70 removes the excess and a closure strip 81 is applied in a manner similar to that employed for the strip 41. The strip 81 is sufficiently wide to allow an unsecured marginal portion 96 to project for use as a tab to facilitate removal. The strip is severed between the packets to separate them. In a modified form of packet, the covering strip may be the same width as the strip 10, and an excess is applied to form loops at the points of severance, thereby forming tabs at the ends of the blocks.
Patent GB-411156-A (GB)
Title: Improvements in, or relating to, the control of hinged members
IPC: E05C17/26
Filed: 1932-12-02
Abstract: 411,156. Locking-levers. WALKER, R. W., and WALKER, E. B., 26, Munro Road, Glasgow. Dec. 2, 1932, No. 34108. [Class 80 (iii).] A device for 'imposing frictional resistance to the movement of doors and other hinged members is arranged so that for any setting, motion is opposed in one direction only and the direction in which friction is introduced is reversible. The friction is variable, and is independent of gravity effects. The device may be applied directly to the hinge of a door, or to the pivot of a stay-bar engaging the door. In the form shown, a bracket 3 fixed to the doorpost carries a pivoted arm 1 engaging at its free end with a slotted bracket 2 on the door, which swings about an axis A. The pivot pin 6 of the arm 1 carries friction washers spring-pressed against a toothed wheel 4, and the arm carries a pivoted ratchet pawl 5 for engagement with the wheel 4. The pawl 5 has a blade spring arm 5a which is engaged with a pin in one of a series of holes 14 in the arm 1 ; by changing the position of the pin either tooth of the pawl may be brought into engagement with the wheel 4 and the pressure of the pawl on the wheel may be varied. The wheel 4 is thus made to rotate with the lever 1 when the latter moves in one direction, against the resistance of the friction washers, but not in the other, and the opening or closing (according to the setting of the pawl) of the door is resisted while the opposite movement is free. Specification 4538/87, [Class 65], is referred to.

Title: Improvements in piezo-electric crystal vibrators
IPC: H03H9/02
Filed: 1945-12-19
Abstract: 611,738. Compound sheet materials. SMITH, B. S., PRATT, E. W., and WRIGHT, C. S. Dec. 19, 1945, No. 34416. [Class 140] [Also in Groups XXXIX and XL(c)] In a piezo-electric crystal vibrator consisting of crystal plates s adhesively secured between metal plates, each adhesive joint embodies a grid of soft metal wires or other filaments so as to ensure a predetermined thickness of the adhesive layer when the parts are pressed together. The invention is described as applied to a sub-aqueous compressional wave sender and receiver as in Specification 611,739, [Group XL(c)], in which it is required to stick quartz plates to a steel plate b<1>. The parts are cleaned with methylated spirit and while heated are coated with a solution of a polyvinyl acetal resin in methylated spirit. A ring plate i carrying a grid j of fine copper wires or plastic filaments is laid on the adhesive coating, and the whole is heated to drive off the solvent and to bind the adhesive to the steel. When the plate has cooled the ring i is forced downwards to break off the wires at the outer edge of the plate b<1>. A desired pattern of quartz plates is arranged on the plate b<1> by means of a template which is then removed. Another face plate is similarly prepared, and an interplate is prepared by coating both faces with adhesive and a grid of wires. The two face plates are then applied to the opposite faces of the interplate and the whole is heated to about 160‹C with about 1 ton pressure and allowed to cool with full pressure maintained. This gives a constant thickness layer of adhesive in the finished unit, being slightly less than the original diameter of the wire as this is somewhat flattened in the process.

Air is allowed to escape from a filled plastics bag by an interrupted seal which is subsequently supplemented by a continuous seal. The interrupted seal may be made after the bag is filled and before it is flattened, or may be made before the bag is filled, filling being effected through another opening, for example through a valve. The continuous seal may coincide with the interrupted seal, or may lie nearer the opening of the bag, or where the material permits, may lie further within the bag. More than one interrupted seal may be provided-e.g. two parallel seals with staggered interruptions. The illustration to the Provisional Specification shows a flat rectangular bag with the interrupted seam formed across the full width of the bag adjacent and parallel to one edge. The outer portions of the weld may, however, be continuous. The interrupted seal may be formed by using a heated castellated blade pressing the material on to a rubber roller provided with a non-stick surface. Alternatively the head of a highfrequency welding machine may be castellated, or the interrupted seal may be formed with the aid of a comb of non-stick material. The seal may be effected by an adhesive. The bag may be filled, flattened and sealed while the filling material is at a raised temperature, and the bags may be stacked on pallets while still warm. The contents may be a granulated organic polymer, grain or feeding stuffs. The bags may be flattened by the device described in Specification 841,644.

Title: Improvements in or relating to apparatus for use in treating lengths of textile fabrics
Inventor: COBURN ROBERT
IPC: D06B23/04
Filed: 1953-12-14
Abstract: Apparatus for steaming fabric comprises a chamber 1, Fig. 1, having steam jets S, rollers 4, 5 mounted on a carrier 6 pivoted at 7, a driving roller 8, a carrier rotating mechanism 11, 13, 13A operated by rise or fall of a roller 10, take away rollers 17, 18, and counterweighted arms 19 pivoted at 21 mounting a roller 20 which guides fabric from the lower roller on to the upper roller so that two plies are wound on the upper roller.  In operation, a long length of fabric 14 is joined at one end to a shorter length 15 and the doubled length 14, 15 is taken into the chamber 1 and passed around the upper roller 4.  The roller 4 is then driven by the roller 8 until the other end of the lower fabric length 15 is about to pass into the chamber 1.  The drive is then stopped and the remainder of the length 15 is drawn into the chamber, taken under the roller 10 and through the outlet 3 to take off rollers 17, 18.  Steam pressure is then built up in the chamber, and the drive is restarted.  The portion of the fabric 15 between the formed roll 4A and the outlet 3 is then drawn tight by the drive, and in so doing raises the roller 10 which causes a pawl 13 to act upon a ratchet wheel 13A and initiate rotation of the carrier 6. The roller 8, assisted by the weight of roll 4A, then rotates the carrier 6 to the position of Fig. 4 via the Fig. 2 position, in which Fig. 4 position the rollers 4, 5 are interchanged.  The pivoted arms 19, Fig. 2, are pushed out of the way during the interchange and held disengaged by a bar 26 pivoted at 27 and carrying a pawl 25 which engages a ratchet 22.  As the roller 5 interchanges.  Fig. 4, it engages the incoming fabric 14 which is continuous in end connected <PICT:0761469/IV(b)/1> <PICT:0761469/IV(b)/2> <PICT:0761469/IV(b)/3> lengths.  A pin 28 on the carrier 6 then lifts the pawl bar 26 and releases the ratchet 22, thus allowing the arms 19 to pivot and the roller 20 to guide fabric 14A toward the fabric 14.  At the same time, the roller 5 is being driven by the roller 8 so that it receives a two ply winding, one ply from the fabric 14, and one from the fabric 14A which is taken off the two ply wound roll 4A. The other ply 15 on the roll 4A is taken off through the exit 3. In a modification, Fig. 6 (not shown), the guiding device 19 may be replaced by a steam jet automatically controlled by movement of the carrier 6, and the ratchet system 13, 13A may be replaced by an electric motor driving a worm and a wheel fixed to the shaft 7, the motor being switched by movement of the roller 10.  Instead of pins 28 on the carrier 6 to engage the roller 20 with the fabric, peripheral bands of fabric gripping pins on the rollers 4, 5, and corresponding recesses for the pins in the roller 8 may be provided.

Abstract: 1280031 Testing bonding GC OPTRONICS Inc 10 July 1969 [28 Aug 1968] 34733/69 Heading G1S [Also in Division G2] Honeycomb panel structure 30 bonds between core and skin are analyzed by superimposing a reconstructed hologram of the skin in a first state on the skin in a second state whereby anomalies in the bond show up as interference fringes, the pressure on the interior of the honeycomb being different from that externally of the skin at the first state and this differential being varied for the second state. A transparent vacuum attachment 20 is fixed to the outer surface of the skin. A pressure differential is created between the honeycomb and the outer skin and a hologram 46 made. The hologram after development is illuminated to give an optical reconstruction superimposed upon the actual skin. The pressure differential is then changed and any anomalies will be seen as fringe patterns. The pressure differential is formed by evacuating the attachment 20 or increasing the internal pressure of the honeycomb where the structure permits this. Alternatively a double hologram may be formed of the two states which upon reconstruction will show fringe lines where anomalies occur, or the whole panel may be placed in an evacuated chamber. Reference has been directed by the Comptroller to Specification 1142702.

Title: Improvements in the saponification of organic esters of cellulose
IPC: D06M11/38
Filed: 1933-12-12
Abstract: Cellulose organic ester materials particularly filaments, threads, fabrics, and ribbons are saponified by means of an organic base in the presence of copper or a copper compound.  The copper may be present initially in the metallic state or in the form of cupric oxide or hydroxide or copper sulphate.  The organic ester may be cellulose acetate, formate, propionate, butyrate, ethyl cellulose acetate, oxyethyl cellulose acetate, or cellulose nitro-acetate, and it may be of high, low, or normal viscosity characteristics. Filaments may be treated continuously with or subsequently to production by dry or wet spinning methods.  They may be stretched subsequently to saponification.  Filaments, and yarns may be treated in warp formation, or in hanks, bobbins, cheeses, or other packages. The organic base may be methyl, ethyl, propyl, amyl, trimethyl, or allyl amine, or tetramethyl ammonium hydroxide or ethylene, propylene, s-dimethyl ethylene, or methyl ethylene diamine, or 1.2.3-triamino propane or a g -diamino-b -hydroxy propane.  The saponification may be carried out at raised temperature and to prevent excessive evaporation the surface of the bath may be covered with oil or wax.  The copper salt may be added to the spinning solution or applied to the materials prior to application of the saponifying agent, or it may be incorporated with the latter. Saponification may be partial or complete.  In an example, cellulose acetate yarn is led continuously in warp formation from a creel through a saponifying bath containing methylamine and to which has been added a small quantity of copper hydroxide.  Specification 207,562, [Class 2 (ii)], is referred to.
