Title: Improvements in charging apparatus for use with annealing ovens, furnaces and the like
IPC: C21D9/00
Filed: 1923-11-16
Abstract: 229,007. Mossay, P. A. H., and Ransomes, Sims, & Jefferies, Ltd. Nov. 16, 1923. Charging and discharging.-In an apparatus for charging annealing-furnaces &c. of the type comprising a travelling carriage with a chargemanipulating arm, the carriage is mounted on ground wheels which are adjustable so that the carriage can be freely manoeuvred in all positions of the charging-arm. The apparatus shown comprises a framework or carriage 1 mounted on a pair of axially-fixed rear wheels 3 and a pair of motor-driven swivelling or steering wheels 2, the forked bearings 4 of the latter being carried by steering columns 5 connected for simultaneous operation by arms 8 and adjustable links or turnbuckles 9 to a hand lever 10. The charging- arm consists of a framework 16 moving on rollers 15 and having at its forward end a pair of supporting wheels 19 and a charge-manipulating fork 20, which can be raised and lowered about the pivot 21 by means of links and levers 22, 23, 25, a longitudinal rod 26, and motor-driven bevel and screw gearing 31, 28. The arm is advanced and retracted by a motor-operated winch 34 and cables 35, and towards the end of its rearward movement a cam surface 57 engages the rollers 15 to lift the wheels 19 on to a platform 46 having a pivoted front edge 47. When the arm is extended a pin 39 on a lever 40 fixed to pivot pin 11 of the steering lever 10 enters a guide groove 41, which is inclined in relation to the longitudinal axis of the arm so that the steering wheels 2 are automatically maintained in such positions that their axis, if extended, would intersect at a point mid-way between the wheels 19. When the arm is retracted the flared end 42 of the groove allows the wheels to be controlled by hand. In a modification, the carriage is mounted on two wheels which, when the arm is retracted, are brought parallel to the wheels on the charging-arm so that the apparatus can be moved through a narrow doorway.

Title: Improvements in processes for producing accelerators for vulcanising rubber and products obtained thereby
IPC: C08L7/00
Filed: 1927-10-05
Abstract: 298,537. Naugatuck Chemical Co., (Assignees of Cadwell, S. M.). Nov. 1, 1926, [Convention date]. Divided on 279,815. Aldehyde - amine condensafion projects. - Halogen-containing derivatives of condensation products of aldehydes having two or more carbon atoms in an open chain and a primary amine are produced by reacting upon the preformed condensation products with a halogen or halogen compound. The products accelerate the vulcanization of rubber. The following examples are given, the initial material being the condensation product of heptaldehyde and aniline :-(1) A. solution of the condensation product in benzene or carbon tetrachloride is treated with chlorine until hydrogen chloride begins to be evolved, wherealter the solvent and excess of chlorine are removed; the product contains 26.4 per cent of chlorine. (2) More generally, the condensation product may be chlorinated so that one, two or three atoms of chlorine are introduced into the molecule by substitution, and if the trichlor product is chlorinated further, two more atoms of chlorine are introduced into the molecule by addition; the pentachlor product so obtained yields a tetrachlor product when boiled with aqueous alkali. Of these products, all except the pentachlor product accelerate vulcanization. (3) The corresponding bromine and iodine derivatives may be made in a similar way. (4) The condensation product is treated, either directly or in ethereal solution, with hydrogen chloride gas in the cold, yielding a viscous mass. The Specification as open to inspection under Sect. 91 (3) (a) contains the following examples : (5) A product similar to that of example 4 is obtained by boiling under reflux a mixture of the condensation product with hydrochloric or sulphuric acid, washing the oily layer several times with an equal weight of water, collecting the later washings, and acidifying them. (6)- Alternatively, the collected washings of example 5 may be treated with sodium hydroxide, to yield an oily product. In further examples the condensation product is (7) boiled with an aqueous solution of ammonium hydrosulphide; (8) dissolved in alcohol and reduced with metallic sodium, and (9) mixed with hydrochloric acid and reduced first with zinc and later with tin. Reference is made also to the hydrolysis of the condensation product with alkali. The Specification is not limited as to the amine used. This subject-matter does not appear in the Specification as accepted.

Title: A method of applying weld-preventing material to a metal sheet and a metal sheet treated with weld-preventing material
IPC: B23K20/18
Filed: 1956-10-02
Abstract: In a method of applying weld preventing material to a metal sheet, there is applied to a portion of the area of the sheet a material consisting of a dispersion of graphite, the major portion thereof having a particle size within the range 1/2 -50 microns, the graphite in the dispersion being within the range of 10-60 per cent by weight and the dispersion having an apparent viscosity of 10,000-180,000 centipoise and the coating is dried to form an adherent continuous elongated pattern area having a thickness corresponding to a dry coating density within the range 1/2 -2\ba1/2 milligrams per square centimetre.  The particles are preferably mostly of the size 5-10 microns and are dispersed by e.g. water to give a solids content of preferably 30-40% by weight.  The material may be brushed or printed or preferably applied by a squeegee over a silk screen having 86-162 holes per inch to deposit a film of preferably 1.3-1.4 milligrams per square centimetre when dried. A preferred material is an ammoniacal hydrosol product known under the Registered Trade Mark "Prodag," having particles mostly of 25-35 micron size.  In an example two unalloyed softened aluminium sheets are cleaned by scratch brushing, the stop weld material is applied to one of the sheets in a passageway pattern by the single pass of a squeegee over a silk screen having 125 holes per inch and is dried to leave a coating of 1.33 milligrams per square centimetre.

Title: Improvements in magnetic memories
IPC: G11C19/08
Filed: 1965-07-15
Abstract: 1,111,317. Circuits employing thin magnetic films. AMPEX CORPORATION. 15 July, 1965 [4 Aug., 1964], No. 30030/65. Heading H3B. A shift register capable of stepping information to the left or right comprises a series of anisotropic magnetic thin film sites 12, 22, 14 &c. arranged alternately in two rows so that neighbouring sites, which may or may not be contiguous, can interact magnetically at their adjacent corners. The easy axis is transverse to the longitudinal axis of the rows. Switching in input site 12 is by domain rotation but in the other sites switching is by domain boundary movement. A clock pulse generator 72, inverters 74, 102 and frequency dividers 76. 90 enable a pulse to be applied to coil 51 or 108 to rotate the magnetization to the hard axis in site 12 coincident with a positive or negative half-cycle being applied to coil 42 according as a " 1 " or " 0 " is to be written in. For stepping information to the right, the phase relation between the signals in the advance coils is such that a positive half-cycle occurs in coils 42, 40, 44, 46 successively at 90 degree intervals. For stepping to the left, switch 78 is changed to produce positive half-cycles in coils 42, 46, 44, 40 successively at 90 degree intervals. Read-out is by energizing read-out winding 120 to induce a pulse of information-dependent polarity in sense line 122. In Fig. 2 (not shown), a central plastic substrate (60) supports on each face copper conductors (52, 53, 54 and 55), an insulating layer of SiO (62), and a permalloy film (64) on a protective substrate (66). This use of two magnetic films (64) provides a substantially continuous path of high permeability thereby minimizing demagnetizing edge effects. The composition and thickness of the magnetic material may be varied at the interacting corners.
