Title: Improvements in the treatment of cellulose materials
Inventor: CAMERON WALTER GLEN
IPC: D06M15/423
Filed: 1959-02-12
Abstract: Cellulosic textile materials, e.g. regenerated cellulose, are crease-proofed and shrink-proofed and their handle is improved and water imbibition reduced by impregnating them with an aqueous solution comprising (1) a water soluble resin precondensate of formaldehyde with a compound containing at least 2 nitrogen atoms each carrying at least one hydrogen atom, each of the nitrogen atoms carrying hydrogen atoms being directly attached to a carbon atom which is itself directly attached to a further nitrogen atom and is doubly linked to an oxygen atom or a third nitrogen atom, or a water soluble ether of such a resin precondensate, (2) formaldehyde and (3) a salt of a bivalent metal from Group II of the Mendel<\>geeff Periodic Table with a monobasic acid which is ionized to the extent of at least 50% when in normal aqueous solution at 18 DEG C., e.g. magnesium chloride, the molecular ratio of metal salt to formaldehyde being at least 1:12, and then drying and heating.  Suitable resin precondensates are the condensation products of formaldehyde with urea, ethylene urea, melamine, dicyan-diamide, acetylene diurein and triazones, e.g. ethylene-bis-5-triazone, methylated dimethylol urea and methylated trimethylol melamine.  After impregnation with the aqueous solution a period of at least 30 seconds may be allowed to elapse before the material is dried and after drying but before curing it may be subjected to a mechanical finishing treatment, e.g. calendering, schreinering or embossing.  Specification 930,132 is referred to.

Abstract: 344,630. Hand driving-mechanism. MURDOCH, L. M. and KENT, B. B., Sterling Works, Davis Street, Poplar, London. Feb. 14, 1930, No. 5013. [Class 136 (ii).] In a folding handle attachment for the driving-wheels of mangles and like machines of the type in which the handle is attached to the wheel by means of a screwthreaded bolt hinged to a pin fixed to the handle, the handle and the wheel are provided with interengaging parts for directly transmitting driving forces from the handle to the wheel. A screw-threaded attachment bolt 3 is pivoted at 4 to a pin 2 on the handle 1, which is held rigid with the wheel 10 in the driving position by interengaging parts 16, 17. The bolt 3 passes freely through a bore 9 in a boss 15 on the rim of the wheel, and is secured by means of a wing nut 12 and a spring washer 14. In order to fold the handle, the nut 12 is loosened, the bolt 3 drawn outwards, the handle 1 turned together with the bolt about its own axis, and the handle is then folded down about the pivot 4 into the vertical position, the recess 16 engaging the lower edge of the boss 15 ; the nut 12 is then retightened.

Abstract: 1424490 Stringing rackets PATENTEX SA 4 Feb 1974 [9 Feb 1973] 05089/74 Addition to 1238571 Heading A6D A racket e.g. a tennis racket in which runs 11 of the stringing are linked to the frame by means of a plurality of attachment elements 1, 10 each having at one end a lug 5 by whioh it is hooked into a hole in the frame 7', Fig. 6, and at the other end a hook 2 by which it is connected to an adjacent element, the hook being in the form of a loop which is joined to the centre portion of the element by a bend 3, string 11 of the stringing following a path, Figs. 6, 7, from one run across the bent portion 3 of one of the elements 1, then between the hook of the same element and the frame, around the connecting portion of the lug of element 10 and then across element 10 at the bent portion 4. In an embodiment the hook is an open loop the width of the opening being slightly greater than the thickness of the material e.g. spring steel wire 2mm. in diameter, of the element and the lug is in the form of a double bend lying in a plane at right angles to that of the remainder of the element, the lug being joined to the element by a bend 4 which lies in the same direction and the same plane as bend 3 thus allowing the run of the string to extend in the same plane as the hole in the frame. The dimensions of the lug is such that when the element is in place the end of the lug bears against the frame adjacent to the hole 9 through which it is inserted and a portion of the lug presses a portion of the hook of the adjacent element against the frame. The last element mounted on the frame has a loop open sufficiently for it to engage the element first positioned, the last element being locked in position by a string 11, Fig. 9 (not shown).

Abstract: 388,209. Drawing and supporting curtains. KERSHAW (MACHINE-MADE BRASSFOUNDERS), Ltd. and TOYE, A. H., Highgate Street, Birmingham. Feb. 23, 1932, No. 5333. [Class 52 (v).] In curtain-supporting devices in which the meeting edges of the two curtains are adapted to overlap and in which the curtains are drawn together or apart by cords led over pulleys, the ends of the curtains are secured to one or more runners connected by flexible couplings to a master runner to which the operating cord is attached. The operating cords 14 are led over guide pulleys 15 and are connected to two master runners 17 one for each curtain. One master runner runs on the straight rail 5 and the other on the rail 6 having a bent overlapping end 8 secured to the straight rail 5 by a bracket 10. The ends of each curtain 22 are supported from two ordinary runners 21 kept a definite distance from their master runner 17 by flexible links 23, acting in compression or tension according to the direction of movement. The ends of the curtains may thus be moved into a position in which they overlap without either of the master runners 17 leaving the straight part of the rail.

Title: Electromagnetic relays
IPC: H01H50/62
Filed: 1943-04-06
Abstract: 576,623. Electromagnetic switches. TRIGGS, W. W. (Pan Akt.-Ges. April 6,1843, No. 5495. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 8, 1943.] [Class 38 (v)] In an arrangement wherein a plurality of magnets of similar construction each control a contact or contacts but some contacts or contact sets are common to two or more magnets, an insulating plate for operating the contacts extends laterally from each armature, the contacts are disposed parallel to the cores of the magnets and the armatures are parallel with the cores and move perpendicularly to the cores. The invention enables circuit arrange ments having many switches in series or parallel and controlled by currents in different circuits to be replaced by fewer switches. Fig. 6 shows an arrangement of six electromagnets with armatures carrying insulating members 16A, 16B - - - 16F, which move in the direction of the arrows when the magnets are energised. The two groups of contact springs between members 16A and 16B represent in reality one group of springs a b which is actuated either by 16A or 16B, the member 16B being arranged in a higher plane than the member 16A and engaging the springs at a different point along their length. The members 16 engage the contact springs in some cases directly as at a3 and in other cases through intermediate hoops or other members such as 20, 21. Energisation of magnet corresponding to 16A will operate a certain group of contacts, and energisation of the 16B magnet another group which includes in part some of the contacts operated by 16A. Contact a2 can be opened either by 16A, or by 16C. Members 16C, 16D overlap so that the contacts operated by 16C can also be operated by 16D which will carry 16C along with it. Members 16E and 16F interlock so that operation of 16E will prevent operation of 16F. Contacts d2 and e1 require operation of both 16C and 16E in order to engage each other.
