Abstract: 1,201,852. Core-making machines and processes. MEAD CORP. 26 July, 1968 [14 March, 1968], No. 35843/68. Heading B3F. A core-making process comprises forming at least two complementary core parts which are to be joined together by matching surfaces. The moulding material adjacent the matching surfaces is compressed to a lesser degree than that in the rest of the core-parts. To assemble a core, the core parts are mated along their matching surfaces and compressed together to bond them. A core-box 13 is filled with green sand and a mandrel 16 (Fig. 4) mounted on a presser plate 17 is forced into the green sand to form a core half (10), the sand at the core-box periphery 28 being less compressed than that at the base of the core. Teeth 34 are formed on the core halves to facilitate accurate matching. The core-box 13 is transported by a conveyer 26, inverted and matched with another core-box 14 containing another core-part. The two core-boxes 13, 14 are pressed together thereby forming a single hollow core which is removed from the core-box 14 by blowing compressed air through a duet (38) in the core-box wall.

Title: Process for modifying the characteristics of structures containing keratin fibres and product thereof
IPC: D06M15/564
Filed: 1963-09-12
Abstract: Structures containing keratin fibres are shrinkproofed and permanent configurations and mechanical effects, e.g. pleating, crimping and calendering, are set therein by reacting them with a polyfunctional isocyanate compound containing at least two groups which are isocyanate or isothiocyanate groups and a monomeric polyfunctional compound containing as the functional groups hydroxyl, carboxyl, sulphydryl or amino groups.  The isocyanate compound may be an aryl, alicyclic or alkylene diisocyanate or diisothiocyanate.  The monomeric polyfunctional compound may be an aliphatic compound containing at least two OH or SH groups including ethylenically unsaturated polyols, a di-, tri- or tetraphenylol compound, an alkandamine or an aliphatic or aromatic polyfunctional acid.  The isocyanate compound and the monomeric polyfunctional compound may be applied to the fibres as a solution in a non-reactive organic solvent, e.g. a halogenated hydrocarbon, an aromatic hydrocarbon, n-butyl acetate, ether or phosphate, p-dioxane, ethyl oxtate, methyl isobutyl ketone, pyridine, quinoline, N,N-dimethyl formamide or acetamide or 2,2,4-trimethyl pentane, by padding, immersing, spraying or from applicator rolls, or as aqueous dispersions when the isocyanate groups are blocked by reaction with tertiary alcohols, secondary aromatic amines which contain only one group having a hydrogen atom reactive with an isocyanate group, mercaptamo, lactamo, imides, monohydric phenols or compounds containing enolizable hydrogen.  The treating solution may also contain a catalyst and a silicone resin.  Numerous examples of suitable isocyanate compounds, polyfunctional compounds, catalysts and isocyanate group blocking compounds are given.  After impregnation the fibres may be dried and cured by heating to 220 DEG -260 DEG  F., aged for 12-24 hours, scoured and dyed with premetallized or acid dyes. During the impregnation the fibres and solutions are preferably maintained at a pH value of 3-9.  Fabrics comprising wool alone or in admixture with synthetic polyamide, polyester, acrylic, cellulose acetate, viscose rayon or cotton fibres may be treated. Other suitable keratin fibres are mohair, alpaca, cashmere, vicuna, guanaco, camel hair or llama. In inserting a desired configuration, e.g. pleat, in a fabric, the fabric may be impregnated, arranged in the configuration and cured. Alternatively the fabric may be impregnated, dried, made into garments, pressed into the desired configuration and cured. Reference is also made to crimped yarns and crimped stretch fabrics.  Crimped yarns may be obtained by knitting a yarn, impregnating, curing and unravelling the knitted fabric.

Filed: 1963-09-20
Abstract: 1,007,877. Ignition systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 3, 1964 [Sept. 20, 1963], No. 37167/63. Heading F1B. An electrical ignition system comprises an induction coil connected in series with interrupter contacts through current-reversing switching contacts which are selectively operable to periodically reverse the direction of energizing direct current through the interrupter contacts without change of current direction through the induction coil. The interrupter contacts 1a 1b are connected in series with a direct current source 2 and the primary 3 of the induction coil through a mannually operable switch 4 having fixed contacts 5, 6, 7, 8 and movable contacts 9, 10. When the switch 4 is changed from the position shown to a position in which the contacts 9 and 10 respectively engage contacts 6 and 8, the direction of current through the interrupter contacts 1a, 1b is reversed without reversal of the direction of current through the primary 3. The transference of contact material produced by arcing, previously occurring from contact 1b to contact 1a, now occurs from contact 1a to contact 1b. By periodically reversing the switch 4, significant build-up of contact material on either contact is prevented. The switch 4 may be operated automatically after each or a series of operations of the interrupter contacts. The secondary 12 of the coil charges a condenser 14 through a rectifier 14; the condenser fires a spark plug 13 through a spark gap 16.

[Also in Division G4] Apparatus generating a voltage whose magnitude is a function of a displacement comprises a thin ferromagnetic film exhibiting planar Hall effect having first terminals positioned to impart electric current parallel to the plane of the film and second terminals positioned to derive a planar Hall voltage in'response to the current, and an applied magnetic field derived from a magnet member adjacent to and movable relatively to the film so as to rotate the internal magnetization thereof; the output voltage being a function of the relative displacement. In Figs. 1, 2 an input shaft 14 rotates symmetrically disposed permanent magnets 10,12 in a plane parallel to that of two films 16,18 of ferromagnetic material deposited on a stable insulating substrate of e.g. glass. The films are composed of iron, nickel, cobalt, or manganese or alloys thereof and preferably of 20% iron and 80% nickel and are energized from a current source 22 through diametrically opposed terminals 24, 26 and 32, 34 while outputs are taken from terminals 28, 30 and 36, 38 on axes at right angles to those of the input terminals. The magnets are of strength sufficient to saturate the internal magnetisation of the films, and the energizing current is uniformly distributed thereon in the angular displacement of 45 degrees between the current axes of the two films, so that the output voltages are respective sine and cosine functions of twice the rotational angle. If the magnets are insufficiently strong to saturate the films, the outputs are sine and cosine functions of the rotational angle. Other function voltages may be generated by varying the uniformity of the current flow in the films or varying the thickness thereof, while by limiting the rotational angle of the magnets and using a geared down input linear functions may be generated. In a modification (Figs. 3, 4 not shown) switchably energizable slip ring fed electromagnets replace the rotatable permanent magnets exciting a single ferromagnetic film; the excitation of the electromagnets being switchable to restore the output to a predetermined value. The output is derived from a single terminal and two other terminals displaced on either side of a point disposed 180 degrees from such single terminal; the two terminals being interconnected by a potentiometer enabling a predetermined offset voltage to be superimposed on the output.
