Title: Improvements in or relating to the production of photo-mechanical printing plates
IPC: G03F5/06
Filed: 1943-01-21
Abstract: 563,028. Half-tone photo-mechanical printing-plates. FIELD, A. E. Jan. 21, 1943, No. 1058. [Class 98 (ii)] A method of producing a half-tone photographic plate includes the step of making an exposure, either successively or simultaneously, through a segmented stop (i.e. a stop wherein the periphery of the aperture comprises or includes a series of inwardly directed projections) and through a non-circular stop, which may be a square or another segmented stop. A circular stop may be used in addition. The aperture may be in the form of a cross, the arms of which are substantially parallel-sided (Fig. 1), or in the form of a cross, each of the arms of which is constituted by a triangle having one of its angles directed toward the centre (Fig. 2), or as shown in Figs. 3, 4 or 5. Two or more stops according to the invention may be used in combination. The stops, when used by themselves or in combination with circular or square stops, may be moved either circularly or laterally, or by a combination of these movements, in their own plane, successive exposures being given for each position of the stop. The stops may be used in. front of, between, or behind the lenses. A stop according to the invention may be used in combination with an iris stop. A fringing effect is produced round the outer portion of the dots, the centre portions being more intense. Various exposures to take account of the tones of the picture may be given. Five successive exposures may be given, change being effected between each exposure ; the fifth exposure may be a flash exposure for black originals. A general exposure may be given with a square stop followed by a second exposure with a segmental stop for the purpose of contrast control. Successive exposures with movement reduce moire. The stops may be made from metal or wood, or may be produced photographically on glass or other transparent material ; a graduated effect may be produced in the latter case. A half-tone screen or a parallel-line grid may be placed in or over the aperture. Specification 431,384 is referred to. According to the Provisional Specification, a segmented stop may be used alone or in combination with a circular stop.

Title: Moulding sand, and a process for the preparation of moulding sand for the shell moulding process
IPC: B22C1/22
Filed: 1958-01-13
Abstract: Moulding sand for the shell-moulding process consists of grains which are coated with a binding agent consisting wholly or mainly of one or more lignin-novolak condensates.  The binding agent may also contain a ketone-aldehyde synthetic resin.  The lignin-novolak condensate may be prepared by the acid condensation with phenol and formaldehyde, of a reactive active lignin made by the saccharification of vegetable substances containing hemicellulose and cellulose by means of 35-41% hydrochloric acid at a temperature not exceeding 50 DEG C., or by replacing part of the phenol in novolaks with active lignin.  Such a coated sand may be prepared by giving the sand a dust-like coating of the lignin novolak condensate, adding a small proportion of a liquid which will swell the condensate, and thereafter permitting the liquid to evaporate and thereby obtaining a dust-free, non-caking, coated sand.  The liquid may be a mixture of a component that boils below 100 DEG C. and a component with a higher boiling point, for example between 150 and 220 DEG C., in which case the coated sand will contain some of the higher boiling point component.  The liquid may also contain a synthetic resin, such as a ketone-formaldehyde resin, or contain constituents capable of forming a ketone-formaldehyde resin during the operation, for example acetone and hexa-methylene tetramine or paraformaldehyde.  An alkaline-earth metal stearate, for example calcium stearate, may be incorporated in the coating to facilitate removal of the mould from a hot cast article. Specification 845,789 is referred to.

Title: An improvement in or relating to means for controlling electric motors
Inventor: PENDLETON JAMES HENRY
IPC: H02P1/06
Filed: 1947-01-15
Abstract: 659,054. Controllers. BRITISH NORTHROP LOOM CO., Ltd. Jan. 15, 1947, No. 1332. [Class 38(iii)] A control switch for an electric motor is combined with and operated by the same handle as a rotary contactor switch and - includes contacts so designed that, when the starting handle of the contactor switch is in the " off position, the motor may be inched in a reverse direction by means of a manually-operable switch, and, when the starting handle is moved towards the " on " position for forward operation, a circuit is first completed through an overload trip and finally through the overload trip and a maintaining switch for a main contactor,whilst return of the starting handle towards the " off " position restores to the original position the means whereby the manually-operable reversing switch can function. The contactor switch has contacts a, b, c, d, its spindle carrying axiallyspaced contacts f, g. A control contact member h co-operates with contactsi, j, and k and is adapted to engage a pivotally-mounted rocking plate m. When the contactor switch is in the " off "' position shown in Fig. 4 the motor p may be inched in the reverse direction by means of contact y. When the starting handle reaches the starting position, contacts c-d, and a-b engage to connect the motor for forward rotation, and contact h3 engages plate m. Contacts k-j short-circuit maintaining contact s and contacts i-j shunt the switch y, the current through the main contactor coil r<SP>1</SP> being completed through an overload trip ne. Continued movement of the starting handle rocks the plate m clear of the contact part h3, the short-circuit being removed from the contact s. When the starting handle is returned to the " off " position the contact part'h3 engages another projection of the rocking plate and re-installs the plate in its original position. In a modification, Figs. 7-11 (not shown), the control contact member has two angularly-spaced spring-biassed contacts one being in the form of a radially-movable plunger which is adapted to engage three stationary contacts in turn to provide " off," " starting," and " running " connections. A blade spring engages a pin on the plunger and forces it clear of the intermediate " starting contact when returning towards the " off " position. In both embodiments the starting handle must be moved to the " off " position before the motor can be restarted after voltage-failure.

Abstract: 137,860. Bosch Akt.-Ges., R. Jan. 5, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Gravity and inertia switches.-A device for preventing electric sparks at the point of rupture of the electric leads of the ignition circuit of a wrecked aeroplane at the moment when the lead is torn asunder by the impact, comprises an electric switch adapted to be operated automatically by the impact to short-circuit the primary winding of the ignition machine. In the construction shown, the device comprises a casing a in which is located a ball b held against a partition c by a spring-pressed rod d and surrounded by a flat spiral spring e bent into cylindrical shape as shown in Figs. 2 and 3. Through the partition extends a pin f abutting at one end against the ball and at the other end against an insulated spring g, the length of the pin being such that a contact i carried by the spring and an uninsulated contact k on the casing are normally held apart. When the aeroplane strikes the ground, the inertia of the ball causes this to move from between the pin and the rod, the spring cage giving way to allow of this movement; the contacts i, k move together and the primary winding l of the ignition machine is short-circuited. The device is re-set by drawing out the rod d, the spring cage returning the ball to its normal position.

[Class 135] [See also Group XXXVII] The operation of a valve 12 or an electric switch is controlled by a fluid-pressure actuated diaphragm 4 which is secured in position by means of the casing 5 of a valve regulating the flow of pressure fluid to one side of the diaphragm. An inlet pipe 6 is rotatably mounted in the casing 5 and has a threaded part which is screwed into a hole in a water-inlet pipe 2. A constricted opening 15 causing a drop in pressure connects the inlet pipe 2 to the outlet pipe 3, which is connected to the chamber above the diaphragm 4 by a passage 16. A plate 8 with an aperture 7 is fitted in the upper part of the casing 5, the aperture 7 being closed by a valve-member 9 when water is flowing in the pipe 2 so that the flow of water to the underside of the diaphragm takes place only through a small aperture 10 in the member 9 and therefore opening of the controlled valve 12 is retarded. When the flow of water ceases, the valve 9 drops from the opening 7 and is spaced from the end of the pipe 6 so that water can flow readily from below the diaphragm, and the controlled valve is closed rapidly.

Title: Process for imparting to wool a gloss and scoop similar to that of natural silk
IPC: D06M16/00
Filed: 1941-02-07
Abstract: 546,915. Treating textiles with liquids &c. WOOL INDUSTRIES RESEARCH ASSOCIATION, PHILLIPS, H. MIDDLEBROOK, W. R. and HIGGINS, A.E. Feb. 7 1941 Nos. 1653 and 14310. [Class 15 (ii)] Wool or material consisting of or containing wool, which has been treated to diminish its tendency to felt by a process not involving the use of a protease, is treated with a solution of papain in order to impart a gloss resembling that of natural silk. For the anti-felting treatment there may be used chlorine gas, sulphuryl chloride, organic hypochlorites or nitrosyl chloride, and the wool is preferably treated when it contains less than its natural moisture content. The solution of papain may be used together with a substance which increases the susceptibility of wool to the action of papain, e.g. sodium bisulphite, hydrogen sulphide, hydrocyanic acid, cyanides, mercaptans, thiol acids, sodium thiosulphate, sodium hydrosulphite, cysteine, cystine, or a mixture of cystine and other amino-acids as obtained by hydrolysis of wool with aqueous hydrochloric acid. Sodium bisulphite also bleaches the wool and such bleaching in presence of the papain has a high degree of permanence to the action of alkaline washing liquors. Preferably, the treatment with papain is carried out at a pH value of about 5À0 and to maintain this value the solution may contain buffer substances such as acetic acid, sodium sesquicarbonate, sodium acetate, or sodium dihydrogen phosphate. The treatment may be effected at raised temperature. The treated material may have a silky scroop and handle as well as a silky lustre. The scroop may be enhanced by a further treatment with a known scrooping agent for natural silk, e.g. a solution of acetic, formic, tartaric, or citric acid, or sodium hexametaphosphate. A pronounced scroop may be obtained by rinsing the fabric, after treatment with papain, with sodium sesquicarbonate, saturating with soap solution and milling, washing, and treating with hexametaphosphate. Alternatively, the non-felting wool fabric may be treated in a milling machine with the solution of papain, and then, after neutralizing, milled in soap. If the scroopy handle is not desired, the papain-treated material is lightly milled with soap, rinsed so as to leave some of the soap in the material, and then pressed while damp. The papain treatment also improves the resistance to felting of. materials which have been given only a partial anti-felting treatment with chlorine gas, sulphuryl chloride, or the like. The treatment may be applied to mixed materials containing wool and cotton, rayon, or other cellulosic fibres, or silk fibres. The gum of raw silk in such mixed materials is partially or wholly removed by treating with a solution of papain containing sodium bisulphite. Specifications 11917/97, [Class 15], 417,719, 464,503, 475,742, and 513,919 are referred to.
