Title: Improvements in or relating to process for preparing new resinous copolymers and thenew compositions resulting therefrom
IPC: C08F232/06
Filed: 1947-07-24
Abstract: Copolymers ranging from viscous liquids to hard resins are obtained by heating a mixture of cyclopentadiene and an unsaturated ester of a monohydric alcohol and a mono- or polycarboxylic acid at a temperature between 390 DEG  and 575 DEG  F. for 1/2 hr. to 30 hrs. Either or both of the alcohol and acid may be unsaturated.  Specified esters are vinyl acetate, vinyl stearate, allyl acetate, allyl stearate, diallyl adipate, phthalate and oxalate, ethyl oleate, linoleate, linolenate, and crotonate, methyl methacrylate, ethyl acrylate, dimethyl maleate, methyl cinnamate, dimethyl fumarate, methyl abietate, triethyl itaconate and aconitate, diethyl acetylene dicarboxylate, allyl oleate, linoleate, crotonate, linolenate, benzoate and cinnamate, vinyl linoleate and triallyl itaconate. Copolymers containing a certain minimum proportion of ester (in the case of vinyl acetate, 25 per cent) are compatible with nitrocellulose; and those containing a lower minimum (5 per cent vinyl acetate) are only compatible with unsaturated triglyceride oils and are soluble in the usual lacquer diluents and in aromatic and naphtha solvents in the formation of varnish films which dry rapidly and are resistant to water, acid and aqueous alkali.  The polymerization may be carried out continuously in a reaction tube surrounded by a heat exchange medium, or in batches in a sealed pressure vessel. The presence or absence of air or of organic peroxides does not affect the products.  Solvents such as toluol and naphtha may be added.  The cylopentadiene may be pure or in the form of fractions containing cyclopentadiene, the dimer or the Diels-Alder polymers, e.g. the trimer, tetramer and pentamer.

Title: Bobbin thread replenishing mechanism in sewing machine with oscillating shuttle
IPC: D05B59/00
Filed: 1971-04-19
Abstract: 1317126 Sewing-machines SINGER CO 19 April 1971 [17 Feb 1970] 20027/71 Heading DIG An arrangement for replenishing a bobbin from the needle thread comprises an oscillatory bobbin drive effective in one rotational direction only. The bobbin 43 is housed in a case 36 provided with a guide slot 60 permitting introduction of the thread for winding in situ, as well as a conventional slot 46. The bobbin flanges have slots 65 to catch the thread, and radial notches 70. An oscillating one-way drive pawl 71 is selectively moved into engagement with the notches 70 of one flange by a lever 80. One arm 91 of a spring 90 is thereby deformed. The bobbin is thus pushed into its case, deforming arm 91 of the spring 90 which normally prevents arm 92 engaging notches 70. Engagement of the second arm 92 with notches 70 to prevent rotation of the bobbin in one direction, is thereby permitted.

Title: Improvements in arrangements for performing logical operations

Abstract: 1,036,233. Semi-conductor logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 14, 1964 [May 24, 1963], No. 20095/64. Heading H3T. [Also in Division G4] A logical operation is performed by feeding a number of independent representations of each operand to a plurality of threshold devices, each of which produces an output when its inputs comprise more than a minimum number of like representations. Fig. 5 shows a redundant version according to the invention of AND and OR circuitry for evaluating the Boolean function f = ((A+B)C+D)E. Each ring is a threshold device and the number within the ring is the minimum number of inputs which must be ONE for the output of the device to be ONE. Each operand A to E is supplied on three separate leads as shown. Fig. 7 (not shown) shows a redundant version of a NOR latch, the outputs of six threshold devices of threshold 2 (corresponding to OR gates) being taken in inverted form, the inverted outputs from each three of them being fed back to constitute half the inputs of the other three. In a similar way, the outputs of threshold devices corresponding to AND gates may be taken in inverted form to give NAND circuitry. Fig. 8 (not shown) shows a Kirchoff-adder-type transistor threshold device with adjustable base bias (i.e. threshold) for trouble shooting. Threshold circuits utilizing magnetic cores, parametrons, tunnel diodes and relay circuits are also mentioned.

Title: Process for the manufacture of fashioned articles from fabric containing artificial filaments, threads, straws and the like
IPC: D06M13/148
Filed: 1934-07-10
Abstract: Fashioned articles of wearing-apparel, e.g. brassieres, suspensories, hats, hat shapes, caps, and girdles are made from a fabric of an organic derivative of cellulose containing a plasticizer, by fashioning the fabric by distortion of the filaments of the fabric while they are in a heat-softened state. The fabric may be woven, knitted, or netted from filaments, bristles or straws made of an organic cellulose ester or ether, together with a suitable plasticizer, e.g. tricresyl or triphenyl phosphate, triacetin, diethyl, dimethyl, or dibutyl phthalate, diethyl or dibutyl tartrate, diethylene or triethylene glycol, para-toluene sulphonamide, or di- or tri-ethanolamine.  The amount of plasticizer may be from 10 to 25 per cent of the weight of the cellulose derivative.  In the case of heavy filaments up to 40 per cent of plasticizer may be present.  The fabric may be placed between the members of mould-like devices of the desired shape which are heated by steam, electricity, flame or the like. Fabrics made of cellulose acetate containing 20 per cent of triphenyl phosphate may be shaped at about 150 DEG  C.  When water or steam is present, a temperature of 100 DEG  C. is sufficient.  If a stiffened article is required a temperature is used which is high enough to cause coalescence of the filaments.  Stiffness may also be imparted to the articles by treating them either with a solvent which will cause coalescence of the filaments e.g. acetone, methyl acetate, or dioxane; with a solution of a cellulose derivative in a liquid which may or may not have a solvent action on the filaments of the shaped article; or with a solution of dammar, copal, elemi, or other resin, or gelatine.  With heavy filaments, sufficient stiffness is obtained by partially or completely removing the plasticizer present during the fashioning operation, e.g. by scouring the fashioned article with a suitable solvent for the plasticizer present.  Heavy filaments containing plasticizer may be obtained by incorporating plasticizer in the solution of cellulose derivative from which the filaments are prepared; by dipping the formed filaments, preferably in the presence of a volatile swelling agent, into a solution of the plasticizer; or by applying the plasticizer to a plurality of fine filaments in the presence of a solvent or latent solvent and coalescing the assembly by the application of heat and/or pressure. In an example, a cellulose acetate straw is caused to dip into a bath containing a 20 per cent aqueous solution of monoacetin, dried in air, knitted or woven to form a fabric, fashioned between or on formers, and then subjected to simple scouring in water and dried. In a second example, the monoacetin of the previous example is replaced by diethylene glycol.  In another example, a solution of cellulose acetate containing 10 per cent of diethylene glycol is extruded to form a straw which is knitted, and the material produced is fashioned between formers and scoured in water.
