Title: Process for soldering metal objects
IPC: B23K1/00
Filed: 1923-09-25
Abstract: 204,709. Amag Automatische Massivdraht Kettenwerke Akt.-Ges. Sept. 29, 1922. Chains; wire fabrics.-The joints of the links of jewellery chains or chain mail are soldered together by coating the finished articles with one or more layers of metals of melting point different from each other and from the work and then heating at high temperatures varying from 650‹ C. to 950‹ C. according to the metal of the blanks. The coating is at the same time united to the metal of the blanks. The work may be first coated galvanically with copper in a bath by a current of 2 volts and 30 amperes and then with solder in a bath by a current of 1 volt and 10 amperes, so that the relation of the copper to solder is as 4 to 3. In a modification a single bath containing salts of copper, solder, and zinc may be used, a current of 2 volts and 10 amperes being applied for about 40 minutes. The links may, before soldering, be coated with substances such as graphite and Paris red for preventing the links from being united to each other. The soldering is normally effected in a space filled with an inert or reducing gas or mixture thereof, or by the use of such gases at such a pressure as to exclude air. The top metal layer may be of higher melting point than the solder layer so as to allow the soldering to be effected in an ordinary atmosphere and without the use of protecting substances. The Specification as open to inspection under Sect. 91 (3) (a) states that reducing or inert gases such as argon, helium, and carbonic oxide may be used. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 11565/14, [Class 83 (iv), Metals, Working].

Patent GB-1591985-A (GB)
Title: Coin tester
IPC: G01B5/06
Filed: 1978-05-31
Abstract: The coin tester serves for separating out coins which exceed a predetermined thickness or which are distorted. It is intended for use in coin-operated machines, especially in coin-operated telephones and vending machines. The coins (M) to be tested roll over a running rail (2) inclined in the direction of movement of the coins and are, at the same time, guided laterally by a guide rule (3) and a lower guide edge (1a). So that the coins bear reliably against the guide rule, the planes of all the guide members are also inclined slightly laterally. Located on the other side is a deflecting rail (7) with a guide face (7b) which is adjacent to a run-in slope (7a). Coins, the thickness of which is greater than the predetermined maximum thickness or which have a correspondingly pronounced distortion, when they roll on the running rail (2), are tilted by the deflecting rail (7) about the upper edge (3a) of the guide rule (3), consequently slip off from the running rail and fall into the coin channel (18), as indicated in the figure for the coin (M') represented by broken lines. Correct coins roll as far as the end of the running rail and there are supplied to the further processing steps. <IMAGE>

Title: Improvements in and relating to the manufacture of rubber
IPC: B22C17/10
Filed: 1922-09-14
Abstract: 208,235. Schidrowitz, P. Sept. 14, 1922. Addition to 193,451, [Class 70, India-rubber &c.]. Single coatings. - The process of the parent Specification, viz., the vulcanization of latex under such conditions that coagulation is precluded, is carried out in the presence of an accelerator at a temperature below those usually employed in hot methods. Several examples are given in the Specification of which the following is typical : to 200 cc of latex containing 30 per cent of rubber preserved with 1 per cent of ammonia, is added a cream consisting of 20 cc. of water containing 3 grams of the accelerator described in Specification 170,682, 6 grams of sulphur, and 3 grams of zinc oxide. After three days at ordinary temperature, the mixture is heated in a boiling water-bath for 2¢-3 hours to obtain a coalesced, but not coagulated, mass of rubber. If the mixture is allowed to stand five days at room temperature, slight thickening occurs, and after straining to remove zinc oxide, excess sulphur &c., the rubber obtained is found to be vulcanized. The time of vulcanization mav be decreased by the use of a " promoter," such as zinc oxide, in an extremely fine state of subdivision, e.g. as a colloidal solution of zinc hydrate in an alkali. Thickening of the latex during vulcanization may be minimized by agitation. Fillers, dyes &c., may be added at any stage of the process, or the vulcanized latex may be applied to fabrics, paper, woven fibres &c. by dipping, spraying &c. The finish may be improved by washing the surface with dilute acid or alkali, or the dried articles may be surface treated with a dilute solution of a gel-forming substance such as an aqueous solution of gelatine or agar-agar.
