Title: Improved method of making bi-metallic strips for thermostats
IPC: C23C24/10
Filed: 1926-04-21
Abstract: 262,644. Miller, F. W. April 21, 1926. Compound forms; pLates and sheets; rods and bars.-Bi-metallic plates for thermostats are made by covering a metal plate with a flux mixed with another metal in a finely divided or granular form and having a lower melting point, a layer of the latter metal, preferably in coarse granular form being then applied over the surface of the mixture and the whole being subjected to the action of heat. A plate 1 of nickel steel is placed in a crucible 2 and covered with a layer 3 consisting of a mixture of powdered fused borax and finer grain brass. A layer 4 of coarse grain brass is added and the crucible heated in a muffle furnace to a temperature sufficient to melt the brass and thus cause it to unite with the nickel steel. After cooling the compound plate may be rolled and cut into strips. The layer 4 may be replaced by a brass plate. The adhesion may be improved by cleaning the nickel steel plate and treating it with acid so as to obtain a grained surface, a suitable acid being obtained by mixing sulphuric and nitric acids with a small percentage of bichromate of potash. Compound plates of other suitable metals may be made in a similar way.

Title: Coin controlled game apparatus
IPC: G07F17/38
Filed: 1931-04-09
Abstract: 371,157. Coin-freed game apparatus. LANGENHAUN, M., Erfurter-Ecke Ritterstrasse, Arnstadt, Thuringia, Germany. April 9, 1931, No. 10521. [Class 27.] Hiring billiard &c. tables.-A coin-controlled device for allowing play for a determined time on a billiard game apparatus of the kind described in Specification 331,609, [Class 132 (ii), Games], comprises a comb 1, Fig. 1, the teeth of which are withdrawn either vertically or laterally from the return ballrunways 30 after the insertion of a coin in a slot 3 and the actuation of a hand-lever 4 which withdraws the comb and winds up a clockwork 2. When the clockwork runs down, the comb is returned and relocks the runways. In the form shown in Fig. 4, the teeth 26 of the comb 1 are withdrawn laterally, the comb being moved to the right against a spring 29 by the hand-lever 4 acting through the coin 16. The comb is held in this position by a bolt 5 engaging a notch 25. During the movement of the comb, a hook 12 engages an adjustable projection 11 of the clockwork to wind this up, and a hook 27 moves a lever 6 until this lever is engaged and retained by a notched lever 7. When the clockwork has run down, a shoulder 28 on a cam disc 10 thereof moves the lever 7 against a stop 7a thereby releasing the lever 6 which is pulled by its spring and raises the bolt 5. The comb 1 is then returned by the spring 29 for its teeth 26 to block the runways 30. In the form shown in Fig. 6, the coin tilts a detent 17 to release a pin 31 from a hook 18 pivoted to an arm 20. The hook 18 swings until a recess 32 engages a pin 33 on a lever 19 actuated by the hand-lever 4. The pin 33 pulls the arm 30 down which, through a link 15 and adjustable lever 14 engaging a toothed segment 13, winds up the clockwork 2. The arm 20 by engaging a pin 34 depresses a lever 8 until it abuts against a stop pin 36 and its pointed end comes below a pin 35 on a lever 9. A hooked member 21 on the arm 20 also engages under a pin 39 on the lever 9, so that, when the hand-lever 4 is released and the arm 20 is returned by a spring 38, the lever 9, which is fast on the pivot 40 of the comb 1, is moved up and rocks the comb to withdraw the teeth 26 vertically from the ball runways. The lever 8 is retained by a pin 42 thereon engaging under a projection 43 on a lever 41 which is released by the segment 13. When the clockwork has run down, a projection 13a on the segment 13 moves the lever 41 to release the lever 8. This is returned by a spring and its point releases the lever 9 so that the comb can return by gravity to obstruct the runways. The comb may be arranged so that its teeth project up through the bottom of the runways to obstructing position.

Title: Improvements in or relating to processes for treating wool
Inventor: WARD CHARLES FREDERICK
IPC: D06P3/20
Filed: 1949-04-21
Abstract: The pH value of a dyebath used for dyeing wool is controlled by the addition of an alkaline salt of pyroboric or metaboric acid with or without free boric acid.  For example, in chrome dyeing of wool the required gradual development of acidity during the dyeing process is controlled by means of boric acid and/or the salt of pyroboric or metaboric acid.  Where the wool is in an acid condition following a previous treatment, the acidity is removed by the addition of an alkaline salt of pyroboric or metaboric acid before dyeing.  In example (1) wool is treated in a bath containing boric acid, Glaubers salt, ammonium acetate and a chrome dye and, after boiling, successive additions are made of boric acid, acetic acid and formic acid, the pH value being 7.14 at the beginning and 5.54 at the end of the dyeing.  Sodium dichromate is then added to chrome the dyestuff. In example (2), scoured wool is pretreated in aqueous boric acid solution, introduced into a bath containing a metachrome dyestuff, sodium dichromate and boric acid, brought first to a pH value of 7.62 by the addition of borax and then to 7.32 by the addition of ammonium acetate and boric acid.  After dyeing at the boil, the colour is finally exhausted by the addition of more boric acid.  In example (3), unsatisfactorily dyed wool in an acid condition which has not yet been chromed, is treated with borax to remove the dye which is then caused to recombine with the wool by the addition of boric acid in three portions followed by additions of acetic acid and formic acid to complete the dyeing.  The dyeing is then after-chromed in the usual manner.

Title: Improvements in or relating to methods of permanently waving human hair
IPC: A61K8/46
Filed: 1952-05-02
Abstract: A process of permanently waving human hair comprises treating the hair with a solution of a reducing agent, allowing the solution to remain upon the hair in wound condition for a time sufficient to disrupt the disulphide linkages in the hair keratin and to soften the hair but insufficient to develop the wave fully, diluting the solution in situ to an extent sufficient to preclude further substantial chemical action and maintaining the hair with the diluted solution thereon in the wound form for a time sufficient to ensure substantial aerial oxidation of the hair and to develop the wave fully.  Subsequent to the full development of the wave the hair may be treated with an oxidizing solution.  The reducing solution may comprise ammonium thioglycollate, an amide of thioglycollic acid, b -mercapto-ethyl amine, b -hydroxyethylmercaptan, monomercapto-dimethyl ketone, b -monomercaptodiethyl ether, ethyl thioglycollate, mercaptoethanesulphonic acid, 3-mercapto - 2 - hydroxypropane - sulphonic acid, ammonium mercaptoethane sulphonate, cysteine hydrochloride, or ammonium N-(a -mercaptoacetyl)-p-aminosalicylate, and its pH may be adjusted to within 6.7 to 9.7 with ammonium hydroxide or a mixture of ammonium hydroxide with sodium hydroxide, ethanolamine or ethylene diamine. The solution may also include a perfume, a wetting agent, an agent serving to make the solution opaque, urea, ammonium sulphate or ammonium carbonate.  The hair may be wound upon curlers, end-papers, or rods and, after the dilution step, may dry naturally or in a drier, and may remain in the wound condition for at least four hours while drying.  The duration of the treatment with reducing solution may vary up to 30 minutes, depending upon the strength of the solution.  Specification 723,917 is referred to.
