Patent GB-250740-A (GB)
Abstract: 250,740. Gledhill, A. H. March 27, 1925. Factory and like time recorders, card-type. - In apparatus provided with an arresting mechanism for preventing movement of the operating lever or impression hammer until a card is correctly placed in its holder the arresting mechanism is so constructed that the card automatically releases it when the operating lever is manipulated. The card acts as a stop to arrest a member which would otherwise actuate an intercepting member to prevent movement of the operating lever or impression hammer. As shown applied to a recorder with clipper mechanism the plunger C is formed with a passage c' to receive a slidable member D on which the portion of the card to be cut rests. The member D has a forward abutment d and a rear arm d<1> and is maintained in position on the plunger C by the cutter c<2>. Bearing against the arm d<1> is a spring-controlled lever d<3> having a forked end d<5> engaging a bail d<6> pivoted to the side frames. If a card is not in correct posit.ion in the card holder the lever d' during the initial movement of the operating lever A rocks the bail d<6> so as to move a depending arm d' with teeth d<3> thereon into the path of movement of a toothed projection d<9> on the operating lever A to arrest its movement. When the card is placed in its proper position the abutment d on the member D is arrested by the card and the lever d<3> is not rocked sufficiently to move the arm d<7> to the intercepting position. According to the Provisional Specification, the bail d<6> carries a finger adapted to engage a tumbler lever on the operating lever and to move it against the action of a spring to a position to engage an abutment on the frame. In the form as applied to a recorder with a vertically movable card support the operating lever A, Fig. 9, carries a pawl e<6> for co-operation with a fixed serrated abutment e<7>, the movement of the pawl being controlled, through a link e<5>, plate e<4>, and bail e<3>, by a bell-crank member e, Fig. 10, pivoted on the card support. When the card is correctly inserted movement of the member e is arrested thereby to prevent the engagement between the pawl e<6> and abutment e<7>. In a modification wherein the printing hammer is prevented from making an impression when a card is not present or incorrectly positioned, the plate e<4>, Fig. 12, is connected by a link f<4> through a spring f<5> and pin and slot connection f<6>. to an interceptor member F which is rocked into the path of a tappet f<1> on the printing hammer shaft f<2> between it and a spring plunger f.

Title: A process for improving the felting shrinkage resistance of wool or wool-containing textile materials
Inventor: SMITH ARTHUR RAYMOND
IPC: D06M15/423
Filed: 1951-10-26
Abstract: The felting-shrinkage resistance of textile material made of or containing wool is increased by introducing into the material an aminoplastic resin from an acidic aqueous true solution of resin-forming components and/or an intermediate hydrophilic condensation product thereof at a temperature from about 80 DEG  C. to the boiling temperature of the solution.  The resins may be urea- or melamine-aldehyde resins.  The resin-forming components may be added to an acidic solution, or an acid may be added to a solution of the resin components, or one component and an acidic substance may be present originally in the solution and the other component subsequently added.  The resin-forming components may be added as solids.  The aldehydic component may be paraformaldehyde or hexamine. An intermediate condensation product may be trimethylol melamine, tetramethylol melamine or dimethylol urea. The acid may be sulphuric, phosphoric, oxalic, tartaric or acetic, and may be added to the solution by continuous drip feed or in portions at intervals, or the solution may include an ammonium salt which develops acidity by reaction with formaldehyde. Alternatively, the acid may be introduced into the solution by using carbonized or acid-milled woollen material.  After impregnation excess liquid is removed from the material, which may then be rinsed and dried.  The solution may include a wetting agent, and after the treatment surface deposits may be removed from the material with dilute phosphoric acid.  After an impregnation the solution may be prepared for re-use by first neutralizing it at an elevated temperature with ammonia or caustic soda, then adding resin-forming components or condensation products to replace the resin taken up by the fabric, and acidifying the solution.  The solution may include an acid dyestuff, and the material may be pretreated or after-treated, if necessary, with a dichromate and a wetting agent, or the solution may include a dyestuff, sodium or potassium chromate and ammonium sulphate.  In examples the solution comprises (21) Lissamine green, Glauber's salt, sulphuric acid, trimethylol melamine and p  formalin; (22) Coomassie red, Glauber's salt, acetic acid, trimethylol melamine and formalin; and (23) Carbolan blue, ammonium acetate, trimethylol melamine and formalin.  In other examples (24) wool fabric is treated with sodium dichromate and cream of tartar and is then impregnated with a boiling solution comprising Solochrome Azurine, a wetting agent, trimethylol melamine, formalin and acetic acid; (25) wool fabric is treated in a boiling bath comprising Solochrome Azurine B.S., a wetting agent, Glauber's salt, trimethylol melamine, formalin and acetic acid to which is later added formic acid and finally sodium bichromate; (26) wool fabric is treated at 95 DEG  C. in a bath comprising Solochrome Azurine B.S., ammonium sulphate, sodium chromate, a wetting agent, trimethylol melamine and formalin.

In a method of comparing the colour of a sample with standard colours, as in the parent Specification, in which a number of identical images of the same small area of the sample are compared with standard colours which differ only very slightly so that the eye can detect slight differences of the sample colour from a desired standard, the ability to distinguish slight differences is increased by rendering the sample colour or the comparison colour temporarily invisible in at least one matching place in the field of vision and filling it either by the comparison colour or sample colour respectively or replacing it by a visual impression which is different in colour, such as medium grey. As shown apparatus similar to that of Fig. 11 of the parent Specification is used there being many modifications of various portions of the apparatus principally: - (1) The members 43 having multiple surfaces to form the multiple images of the sample are so arranged as to be movable, such as by mounting a series of them on a rotatable disc 144, or individually mounting such member 43 with an operating knob or toggle switch Figs.47-52 (not shown). (2) The members 43 are associated with magnifying lenses 69 or 69' or the members 43 themselves may have curved surfaces to form such lenses, Figs: 37-45 (not shown). (3) The casing for the apparatus is made in two parts 155, 156, Figs. 2-7 and Figs. 52, 53, (not shown), and the light path is mainly in a single plane 157 which is the plane of division and facilitates mounting of the various optical elements. (4) The sample may be illuminated at various angles depending on the arrangement of mirrors 31, 41, to suit various types of samples and interchangeable units may be provided for engaging the casing, Figs. 52 and 54-62 (not shown). (5) The colours of fluorescent samples may be determined using a detachable ultraviolet unit having a quartz lamp 182, Figs. 53 and 63 (not shown) and cooling blower 181. (6) The diaphragm plates 2-4 may be rotatable or slidable and formed in various ways Figs. 8-14 (not shown). (7) The standard colours on surfaces 32, 33, may be in one plane or arranged as a movable band, Fig. 30 (not shown) or on a cylindrical carrier Figs. 27-29 and 36 (not shown). (8) Two eyepieces O c I, O c II are provided for binocular vision the incoming ray being divided by a beam splitter or a rotatable mirror 174. A second observer may check the result by using a slidable eyepiece O c III having a mirror 175.
