Title: Improvements relating to the molding and vulcanization of endless belts of rubber composition
IPC: B29D29/10
Filed: 1948-02-23
Abstract: 660,984. Moulding power transmission belts. GATES RUBBER CO. Feb. 23, 1948 [July 13, 1940], No. 5318/48. Class 87(ii) An endless transmission belt of rubber composition having a layer of tension cords 18 is made by curing the belt in an endless mould in which the belt is positioned with its outside surface to the inside, and reversing the cured belt whereby that portion of the belt between the cords and the inside of th belt will be put under compression and that portion between the cords and the outside will be put under tension. The belt (or belts) is cured in a circular sectional mould consisting of parts 10, 11. The tension layer is transversely concave in shape with the convex surface near the bottom of the mould so that the cords nearer the bottom of the mould are shorter. Initially they are all equally tensioned. After the belt has been turned inside out the cords near the middle of the belt will be under greater tension than those near the side walls and variation in tension will be uniform from both sides to the middle of the belt. With a belt of the kind shown on the left-hand side of Fig. 3, no variation in tension of the cords will result on reversal of the belt. Belts of rectangular cross-section may be made using the method of the invention. U.S.A. Specifications 1,748,626 and 2,194,833 are referred to.

Abstract: 285,794. Package Machinery Co., (Assignees of Smith, E. L.). Feb. 18, 1927, [Convention date]. Parcelling articles.-A method of folding a wrapper around an article consists in bringing the inner faces E<1>, E<2> of opposite ends of the wrapper together at one side of the article 1, folding one end E<1> back upon itself, and folding the end E<2> so that it overlies the previously folded end, a sealing medium securing each of the overlapped ends to each other and to the body of the wrapper. The portion E<2> may extend beyond the portion E<1>. The overlapping portions are then heated to make a tight seam, if the wrapper is of waxed paper, or merely pressed to cause them to adhere if they are gummed. The wrapper extends in tube-like form beyond the ends of the article, and to secure these wrapper extensions the lower, and side extensions are first folded inwardly then the upper extensions are brought down into overlapping relation therewith, and finally the whole is sealed.

Abstract: 871,890. Taping electric conductors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 13, 1958 [Feb. 18, 1957], No. 5432/57. Class 109. A machine for taping a conductor in open coiled form comprises a taping head for receiving the conductor and includes means for carrying a supply of tape, feeding means which are adapted to move the conductor and the means for carrying the tape supply relative to one another lengthwise of the conductor, and means which as the relative movement takes place are adapted to move the means for carrying the tape supply around the conductor between adjacent coil turns of the conductor, whereby with an end of the tape secured to the conductor, the tape will be wrapped round the conductor. An open coil 1, supported by free rollers 3b and fed by rollers 3, 3a, driven in the same direction and at the same speed by an electric motor 8, passes through a polishing wheel 34 driven by a motor 41 and cleaning baths 35 to a taping head 4. Resilient frusto-conical rollers 25a driven off a shaft 18 rotated by the motor 8 through belt gearing 9 grip a turn 1c of the coil 1 and feed it through an aperture in a carrier wheel 22 rotated by a gear-wheel meshing with a gear on the shaft 18. On the carrier wheel 22 is obliquely mounted a drum of tape 22b from which tape passes on to the coil 1 as the drum 22b passes between adjacent turns 1c of the coil 1. Pivoted at 28 to the carrier 22 is a bellcrank lever 27 one end of which carries a weight 29 which under the action of centrifugal force moves outwardly of the wheel 22 and thus urges the other end 27c of the lever 27 against the tape on the drum 22. When the diameter of tape on the drum reaches a predetermined value the weight 29 is able to move outwardly sufficiently far to close a micro-switch 31 connected to the circuit of the motor 8 and thus stop the machine for replacement of the tape.

Treatment of the resin-peptide with anhydrous hydrogen splits off the peptide, and removes any protecting groups except TFA. The amino protecting group is t-butoxycarbonyl, amyloxycarbonyl or o-nitrophenylsulphenyl, which may be removed by trifluoroacetic or hydrochloric acid, without affecting the other protecting groups. In the examples the serine, tyrosine, glutamic acid and aspartic acid residues are protected with benzyl or the p-methoxy, p-chloro or pnitro derivatives, or benzhydryl, which may optionally protect the tyrosine radical. The histamine residue is optionally protected with the above groups or with carbobenzyloxy, tosyl or dinitrophenyl. The arginine residue is protected by tosyl or nitro. The lysine residue is protected by trifluoroacetyl, or carbobenzyloxy or the 2-chloro, 2-bromo or 2,4-dichloro derivatives thereof. Treatment with anhydrous hydrogen fluoride, where the lysine residue is not protected by TFA, yields the unprotected peptide, which may also be obtained by the treatment of the TFA derivative of the peptide with an aqueous base (e.g. piperidine, ammonium hydroxide).

Abstract: 1530237 Semiconductor devices DATA GENERAL CORP 14 Feb 1977 [14 May 1976] 06112/77 Heading H1K A metal/semiconductor interface is made by forming a patterned oxide layer 602 on the surface 603 of a semiconductor substrate 601 using photoresist, passivating the exposed surface 603 against the formation of nascent oxide, by exposing it to a nitrogen plasma containing neutral nitrogen atoms, and depositing a metal on the surface 603. The substrate 601 is annealed to form the metal silicide. The metal may be Pt, Mo, Al, Ti, Rh, Pd, or W and it forms a Schottky or ohmic contact depending on the doping concentration of the substrate 601. The nitrogen atoms form a protective covering on the surface 603 and thereby prevent the formation of the nascent oxide before the metal is deposited.
