Filed: 1916-03-15
Abstract: 101,179. Moody, F. E., and Pessers, Moody, Wraith, & Gurr. March 15, 1916. Tivoli billiards and the like.-Relates to game apparatus of the type described in Specification 10,036/15, and consists in the addition of means similar to that described in Specification 100,980, whereby the coin inserted to release the balls for play serves also to free a check-delivery mechan. ism, so that a check is delivered prior to the commencement of the game, the resetting of the check-delivery mechanism being effected by a part of the apparatus operated at the commencement of the game. The coin inserted in a shoot 63 strikes a pin 64 on a spring-controlled lever 65 and rocks that lever so as to lift its toothed extremity 67 from engagement with a projection 68 on an operating-slide 69; thereupon a spring 77 moves the slide to the left, transferring a check from a storage column 82 to a delivery shoot 84. The slide is reset by a lever 87 connected to a spindle 31, which serves also to operate a gate for allowing the balls to pass singly to a projector 2. The coin, in addition to releasing the delivery slide 69, releases the balls for play as follows. The pin 64 on the lever 65 rocks a spring-controlled bell-crank lever 20 from beneath a pin 18 on a lever 15, which thereupon drops and removes a blocking-arm 13 from the open end of a magazine 11 containing the " winning " balls; simultaneously, owing to the withdrawal of a stop 40 on the lever 15, the " losing " balls also pass into play. As described in the prior Specification 10,036/15, the game is played with six balls, and balls caught in the movable cup C pass to the magazine 11; if the player succeeds in catching four balls, he can effect the return of all six balls to the " play " position by rotating a spindle 46, which serves also to operate the projector 2. The fourth ball in the magazine 11 forms an abutment for a sliding arm 23 pivoted at 36 to a link 22, so that the link turns about the pivot 36, a projection 37 rocking the bell-crank 20 and freeing the lever 15.

Abstract: 720,697. Toothed gearing. AKTIEBOLAGET BOFORS. Feb. 12, 1953 [Feb. 15, 1952]. No. 3947/53. Class 80 (1). A method and apparatus for measuring play in a transmission mechanism comprises connecting an indicating device 35 to the output member 3 of the transmission, .moving the input member 1 in one direction by an arm 5 until the indicating device gives an indication, moving the input member in the other direction until the said indication ceases and measuring by means of a micrometer screw 6 the amount of movement between the indication and the cessation thereof. The indicating device 35 is operated by a feeler member on a shaft 13 coupled to the output member 3 through a coupling 9. The feeler member 20 has three resilient strips 24, 25, 26 carrying electrical contacts 27, 28, 29 co-operating with fixed contacts 30, 31 and 32 respectively. These contacts are connected in circuit with a battery 34, resistance 37 and a measuring dial 36 of the indicating device 35. On movement of input member 1 in one direction contacts 27, 30 are adapted to give an initial indication by means of an arcing contact until contacts 29 and 32 meet when a steady reading of dial 36 is shown. On movement of input member 1 in the opposite direction and when the play has been taken up the contacts 29, 32 are broken, arcing contact between 27 and 30 is re-established and then contacts 25 and 31 are made to give a steady reading of the dial 36 again. The feeler member 20 is secured to shaft 13 by a frictional device so that slip will occur to prevent damage to the contact device on excessive movement of the input member.

According to the invention the strengths of the bonds between each of the self-adhesive tapes and the respective member to which each is directly bonded is greater than the strength of the bond between the non-adhesive surface of the single tape and the double-sided tape whereby, when the two members are drawn apart, the two tapes each remain adherent directly to the respective said members and the seal directly between the non-adhesive surface 3 of the singlesided tape 1 and the double-sided tape is releasably broken allowing the two members to be released and subsequently re-sealed repeatedly. As shown in Fig. 2, 4 one member comprises the front face of the box 10 and the other member comprises a tab 13 on a cover flap 11 of the box. The self-adhesive material 14, comprising single and double-sided tapes 15, 16 respectively is located on the outside surface of a letter card, Fig. 6, which has a main fold 20 and a secondary fold 21 the latter forming a flap 22, which can be folded down to contact the tape 16 and seal the card. On opening the card, the tape 16 adheres to the flap 22 the tape 15 remaining in its original position. If it is desired to mask the tape 16 it can be folded down on to the correspondence face 23 of the card. The surface 23 adjacent the fold 21 may be pre-treated with release agent such as wax. A letter card, Figs. 10-13 (not shown), has two main fold lines (30, 31), a window (33), and a closure flap (22) the self-adhesive material (14) being first secured to the card adjacent the fold (31) and a line of perforations (35) being provided to render the lower panel (36) detachable. Self-adhesive material may be provided around all of the edges of the letter cards. The sealing method can also be used in the sealing of frame cards for photographic negatives, Figs. 14-16 (not shown). The double-sided tape 16 may, prior to use, be protected temporarily by a masking strip, not shown, e.g. of waxed paper.

Title: A process for producing urea-formaldehyde resins
IPC: D21H17/50
Filed: 1948-02-12
Abstract: A clear water-soluble stable condensation product is produced by heating 1 mol. urea with 2-2.5 mols. of 37 per cent aqueous formaldehyde in two stages, first in the presence of 0.3-1 per cent by weight of the aqueous formaldehyde of a mixture of borax and boric acid in proportions to maintain a pH of 6.7 to 7.3, and then after addition of 1-2.5 per cent by weight of boric acid based on the weight of reaction mixture.  A polyhydric alcohol such as glycerol, polyglycerol, ethylene glycol, diethylene glycol, mannitol or sorbitol may also be added in the second stage.  Condensation may be completed by removal of water by distillation followed by dilution to the desired solids content and adjustment of the pH to a value above 7.  The products are readily absorbed by cellulosic materials such as paper or cotton and may be used to increase the wet strength of paper (see Group VIII), or to impart abrasion resistance and dimensional stability to textiles.  They show unusual adhesion to glass and are suitable as primers for glass fibres and glass cloth used for lamination. They may be added to paper pulp together with alum or clay, or may be used for paper coating compositions with clay, pigments, e.g. TiO2, starch and accelerators.
