Title: Improvements in telephone or like signalling systems
IPC: H04Q1/38
Filed: 1933-01-20
Abstract: 390,786. Static contact rectifiers. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 20, 1933, No. 1954. Convention date, Jan. 20, 1932. [Class 37.] A cell passing only voltages above a particular value and applicable to telephone systems, comprises oxidized metal plates contacting with solid conducting bodies rich in oxygen, for example a superoxide. As shown in the Figure, oxidized aluminium plates 4 contact with layers 5 of manganese dioxide or lead peroxide. The assembly being held between insulating plates 1, 2 by bolts 3. Terminals 7 and a protective cover 8 are provided. The films of oxide on the plates are formed electrically by immersing the aluminium plates in a solution of potassium bichromate and applying potential, of a value slightly less than the working value of the cell, until current ceases to pass. The cell will then pass voltage only if it is of a higher value than the forming voltage, e.g. a cell to operate at 40 volts is formed at 35 volts. The cell can be used as a rectifier.

Abstract: 376,194. Sewing-machines. UNITED SHOE MACHINERY CORPORATION, Paterson, New Jersey, U.S.A.-(Assignees of Ashworth, F. ; Wenham, Massachusetts, U.S.A.) Jan. 23, 1932, No. 2102. Convention date, March 9, 1931. [Class 112.] Work supports ; presser feet.-A curved needle, awlfeed lock-stitch sewing-machine of the kind described in Specification 23478/10, [Class 112, Sewing &c.], has its work support and presser foot modified to adapt it to stitching the uppers of moccasins. The work support comprises two angularly disposed faces with a slot for passage of the needle, and the presser is wedge-shaped to fit into the angular space between the faces. The needle 2, feed awl 4, loop spreader and rotary hook for passing the needle loops round the bobbin are as described in the abovementioned Specification. The work support 24 is bolted to the carrier 28 secured to a bracket on the machine frame. The support has a pair of angularly disposed work-supporting faces 32, 34 for holding the top-piece 18 and ramp 20 in required relationship for stitching. The support is recessed at 36, Fig. 3, to allow passage of the needle and awl. The presser foot 38 is wedge-shaped to fit into the angle formed by the work-supporting faces and is cut away at its apex to allow passage of the needle and awl. Only a small part of its pointed edge remains, as shown in Fig. 3. This enables the work to be readily manipulated round corners. The mechanism for operating the horn 40 carrying the presser foot to lock it in work-engaging position during the passage of the needle and for retracting it during the awl-feeding movement is the same as described in the above-mentioned Specification.

Abstract: 547,487. Conveyers. KING, Ltd., G. W., and KING, D. M. Feb. 24, 1941, No. 2480. [Class 78 (i)] Carrier spindles 10 interconnected by a travelling belt or chain 13 and running on an I-section beam 11 are rotated during their travel by frictional engagement of a roller 15 secured on each spindle with a belt 16 resiliently pressed against the.rollers. The belt 16 may travel at a speed or in a direction different from that of the belt 13. The rollers are supported against the thrust of the belt by fixed rails 33, 34. The belt 16 is attached by links 17 to an endless chain 18 passing around sprockets 19, 20 carried on frame members 21, 22, and, is driven by an electric motor 23 supported by the frame member 21. The frame members 21, 22 are supported by movable carriages 24, 25, having wheels 26 running in channels 27, the carriages being urged towards the spindles by compression springs 28 located between fixed abutments 30 and brackets 29 on the carriages. Means for preventing rotation of a spindle throughout predetermined distances in its travel comprises a member 37 supported on the spindle immediately above the roller 15 and having pivoted thereon a spring-loaded lever 36 carrying a locking plunger 35 which enters holes in the upper face of the roller 15, the plunger being raised to allow rotation of the roller by engagement of a projection 39 on the lever 36 with a cam 38. In modifications, (a) the rails 33, 34 and carriages 24, 25 may be omitted, the load being slightly offset from the centre line of the beam 11 so that the weight of the load and carrier is partly taken by the belt 16, and (b) the rails 33, 34, may be replaced by another band driven from the band 16 and in a direction opposite to that of the latter. The invention may be applied to sand-blasting bomb. cases. According to the Provisional Specification the off-setting of the load may be combined with the spring-loading of the band.

A wheelbarrow or like hand propelled vehicle has a single wheel axle B<1> and comprises a body framework A<2>, C<1>, C<2> carried by the wheel axle for supporting the body A of the vehicle, a handle framework D<2>, D<3>, D<4> which carries the propelling handles D<5> and is pivotally connected to the body or body framework at A<1>, and means whereby the wheel or wheels can be locked against rotation relatively to the body framework so that continued application of the propelling force on the handles after such locking will cause the body to swing round the wheel axle and tip out its contents. In the embodiment shown a wheel B carries one element B<2> of a dog clutch, the other element B<3> of which is mounted on a lever E pivoted at El to the body frame. The clutch is biased toward the closed position by a spring E<2> but is normally held open by a catch F. The catch F is rotatable about a cross-bar D' of the handle frame, by means of a lever G, against a spring G<4>, and comprises a notch F<1> which coacts with the lever E, and a curved upper face F<4> which guides the lever into the locked position after tipping. A modification is described (Figs. 5 and 6, not shown), in which a lost-motion connection between the wheel and the body allows some initial tipping before the member C<1> begins to rotate about the hinge A<1>, the total tipping angle being thereby increased. In a further modification, Fig. 7 (not shown), a curved ramp is formed on the end of the body which contacts the ground after a predetermined rotation of the body about the wheel axle.

Title: Improvements in or relating to the production of chemical conversion coatings upon metal surfaces
IPC: C23C22/78
Filed: 1962-01-24
Abstract: In a process of forming a chemical conversion coating on a metal surface, the metal is first pretreated with a pickling solution which contains aqueous phosphonic acid and coating forming metallic cations such as Fe, Cu, Cr, Zn, Mn, Ca and Mg, and then directly treated with the coating forming solution to form a phosphate, chromate or oxalate conversion coating.  The metals treated may be iron, steel or zinc in which case the coating solution is an aqueous acidic heavy metal phosphate solution preferably containing Zn and/or Mn and/or Ca orthophosphate, an accelerator such as a nitrate, nitrite or chlorate, and a soluble dehydrated phosphate, e.g. tripolyphosphate or hexametaphosphate.  For treating aluminium the coating solution is an aqueous acidic solution containing hexavalent chromium and fluoride ion and optionally orthophosphate ion.  The oxalate coating bath contains oxalic acid, manganese and nitrate ions.  The pretreating pickling solution having a pH less than 1 may contain 1-30% H3PO4, up to 10% HNO3, 0.1-8% of the coating forming metallic cations, 0.01 to 0.1 g./1. of a non-ionic wetting and/or emulsifying agent such as the condensation products of ethylene oxide with alkyl phenols or fatty alcohols, and a minor proportion of soluble lithium and/or titanium compounds, or of a soluble dehydrated phosphate.  The metallic cations in the pickling solution are preferably the same as those present in the subsequent coating solution and are introduced as the soluble compounds, e.g. phosphate or nitrate. After treating in the pickling solution, the metal is treated with the coating solution without intermediate rinsing and the coated metal may be rinsed with chromic acid.  When the coating is used as an insulating layer the phosphate coating is fired at above 300 DEG  C.
