Title: Apparatus for applying a paper slip to the bound edge of a book or pile of sheets
Inventor: SUGIOKA YASUJI
IPC: B42C9/02
Filed: 1970-07-14
Abstract: 1,254,404. Bookbinding. TAIYO SEIKI CO. Ltd. 14 July, 1970 [24 July, 1969], No. 33999/70. Heading B6A. Apparatus for applying a strip of paper, such as marble paper, to the back and adjacent parts of the sides of a bound pile of sheets comprises (a) a pair of spaced elongated guide members 3, 4, Fig. 1, to which the strip M, Fig. 3, is fed with its upper surface coated with adhesive, (b) a pair of spaced bars 21, 22 between which the pile 20 is inserted so that the bound edge of the pile contacts the adhesive surface of the strip M, (c) a pair of spaced pressure rollers 32, 33 disposed beneath the guides 3, 4 and (d) means for causing the bars 21, 22 to move towards each other to grip the pile 20 and move the pile downwardly between the rollers so that the strip is applied around the bound back of the pile 20. The bar 21 is fixed to a member 23 carried by a post 28 biased downwardly by a spring 30 but normally held in raised position by a cam 32 on a shaft 31. The other bar 22 is fixed to a lever 24 pivoted to the member 23 at 25 and is biased towards the bar 21 by a spring 26; a cam surface on the lever 24 engages a roller 29 on a fixed part 2 of the machine so that normally the bars 21, 22 are well spaced apart to permit insertion of the pile 20. After its insertion, the pile moves downwardly under gravity carrying with it the strip and approaches the space between the rollers 32, 33 which are spring-urged towards one another. At the same time the pile actuates a switch 34, Fig. 3, causing the shaft 31 to be driven, so that the cam 32 allows the post 28 and therefore the bars 21, 22 to move downwardly. During such movement, the lever 24 becomes free of the roller 29 so that the spring 26 causes the bars 21, 22 to clamp the pile. As downward movement continues, the rollers 32, 33 cause the strip to be wrapped around the bound edge. Eventually, the bound edge and strip, make contact with a felt surface on a spring-supported plate 51. Subsequent rotation of the cam 32 causes upward movement of the post 28 and the bars 21, 22 with the pile clamped therein, until the roller 29 engages the lever 24 and opens the bars 21, 22. The bearings 47, 48, Fig. 1, of the rollers 32, 33 are carried by levers 63, 64 Operated upon by cams 68, 69 on the shaft 31 so as to cause the rollers to be separated as the pile 20 moves upwardly, thus preventing possible stripping off of the strip M during such upward movement. The strip M is supplied from a roll of the material and after passing through an adhesive applying device (77, Fig. 5) is fed by rollers (73, 74) along the guides 3, 4 until its leading edge actuates a photo-electric switch 8 which causes the feed to be stopped and a cutter comprising a heated wire (82) to be actuated to sever the required length of strip.

Title: A device for cutting individual sections from a length of adhesive tape
IPC: B65C11/00
Filed: 1959-10-08
Abstract: 922,155. Cutting apparatus. CLAUS KOENIG G.m.b.H. Oct. 8, 1959 [Oct. 8, 1958], No. 34208/59. Class 31 (1). [Also in Groups XV and XVII] A cutter 7 for severing adhesive tape has a covering medium source associated with the cutting device, to provide a non-adhesive gripping tab on one side of the cut. As shown, the covering medium is a solid block 8 e.g. silicone wax, chalk or magnesia which applies a covering layer to the adhesive tape on contact or by abrasion. The block 8 may be mounted in a receptacle 6 such that it can readily be replaced, and on leaf springs or sponge rubber so that it can yield resiliently. The covering medium may also be in powder, liquid or mastic form, and in such cases could be applied by a delivery roller to a zone of the adhesive tape which is to be covered. In the case of a handoperated appliance, Fig. 1, the covering source is disposed immediately in front of or behind the cutter so that when the tape is applied against the cutter it is simultaneously covered with the medium. As applied to machines for sealing packages, Fig. 12, the adhesive tape 2 is guided by rollers 30, 31 and is forced against the cutter 32 by a block 37 of a covering medium e.g. chalk which is reciprocated by cam 43. The block 37 acts against a spring-pressure counter plate 35 and is returned by a spring 41. After cutting the pull on the tape causes the end to be pulled out of the clamp between the chalk and the counter plate causes an abrasive action on the chalk. In a further modification the block 37 is replaced by a rotatable cylinder of chalk &c. and the counter plate 35 by a roller. A covering medium in liquid form may be applied to the roller.

Title: Drawing of synthetic filaments
Inventor: O'DONAHUE JAMES
IPC: D02J1/22
Filed: 1961-09-28
Abstract: In drawing synthetic filaments by a draw-twister in which units comprising a heated feed roll, a draw roll and a packaging-means at a number of positions are driven from a common source of power, these units are made to rotate slowly during stringing-up to obviate breakages on starting by reducing the time during which the filaments are allowed to dwell on the heated surfaces during the stringing-up operation.  To this end a secondary, smaller, source of power is connected by a free-wheel coupling to the gearing or other transmission by which the units at each position are driven by a primary power source.  During stringing-up, the units are driven at speeds between 1/100 th and 1/1000 th of the normal speed; the units may additionally comprise a heating plate and the traveller ring of the packaging means may be magnetized; and the filaments may be of polyesters and copolyesters (e.g. those of terephthalic acid with ethylene glycol or 1, 4-cyclohexane dimethanol) polyamides and polyolefines such as stereo-regular polypropylene including isotactic polypropylene.  It is stated that the process is applicable to other forms of draw twisters than those using a heated feed roll.

Filed: 1929-11-18
Abstract: 338,003. International Industrial & Chemical Co.; Ltd. Nov. 21, 1928, [Convention date]. Barium carbide is made by heating barium oxide or carbonate with carbon and an inert, infusible, porous substance such as bibarytic silicate, in a current of hydrogen, hydrogen and carbon monoxide, methane, &c. No fusion occurs at the temperature of 1400-1600‹ C. used, and the product is treated to produce acetylene and baryta which is re-used. The bibarytic silicate is added as such or formed during the reaction by adding silica or silicates. The reaction gases may be drawn off by a vacuum. The mass is cooled and treated with steam or water to give acetylene. The product, or part thereof, may be washed with hot water to dissolve the baryta and decompose the bibarytic silicate giving baryta and the insoluble monosalt. The insoluble residue, which also contains excess carbon, silica occuring as an impurity in the carbon, and sometimes barium carbonate, is suspended in water and treated with carbon dioxide till neutral. Caustic alkali or alkali carbonate is then added to dissolve the silica, and the residue, after addition of carbon, and barium carbonate equivalent to the baryta removed, is used again for making carbide, the monobarytic silicate recombining with silica to form bibarytic silicate.
