Filed: 1928-12-15
Abstract: 302,589. Telefonaktiebolaget L. M. Ericsson. Dec. 17, 1927, [Convention date]. Thermionic generators; filter circuits.-In a thermionic generator, harmonics are eliminated by arranging the frequency-determining circuit L C1 C<1>2, C<11>2 as a filter through which both the output and the oscillations utilized for reaction are passed, the capacity of the input condenser C1 being greater than the output capacity C<1>2 C<11>2. The Figure shows a generating- valve 6 transformer-coupled to the filter input 1,. the voltage across condenser C<11>2 being utilized for reaction and the total output voltage being applied to an amplifier 8. In a modification (Fig. 2, not shown) the generating-valve isdirectly coupled to the filter input, the anode being fed through a choke. By varying the ratio of the capacities C1, C<1>2 C<11>2, the desired voltage for reaction may be secured and the input impedance may be adjusted to suit the valve used as a generator,

Title: Improvements in or relating to treatment of dyed anodized aluminum
IPC: C25D11/24
Filed: 1962-10-02
Abstract: An anodized and dyed aluminium surface is freed from "smut" deposit formed in a final sealing operation, by treating with dilute sulphuric acid, up to 14% by weight, for a short time, e.g. 15-120 seconds, at normal temperatures. The "smut" is removed without bleeding the dye.  In examples, aluminium anodized by known methods is dyed in a water-soluble or solvent-soluble dye, and is sealed, e.g. by treating with a 1% mixture of Ni, Co, and Cu acetates.  The treated aluminium is then immersed in boiling water, and finally in 7% H2SO4 for one minute at 24-27  DEG C.  A small amount of a wetting agent may be added. Specification 964,144, U.S.A.

Title: Improvements in or relating to molybdenum lubricants and their manufacture
Inventor: HUGEL GEORGES
IPC: C07F11/00
Filed: 1955-01-07
Abstract: A lubricant for metals consists of a mixture of a molybdic xanthate of an alkanol containing less than 6 carbon atoms and a mineral lubricating oil.  In use, the xanthate is decomposed by the frictional heat and molybdenum sulphide is deposited on the metal surface.  A preformed coating of molybdenum sulphide may be produced on metal parts to be subjected to friction by heating the metal parts in a mineral oil solution containing 0.5-10 per cent by weight of the above-mentioned xanthate at a temperature above the decomposition temperature of the xanthate.  The metal parts, thus coated, may be lubricated by means of a mineral lubricating oil containing 0.5-6 per cent of the above-mentioned xanthate or of molybdenum blue, or by means of a mixture of 0.5-6 per cent of a thiomolybdate of a nitrogenous base (viz., an alkylamine, an alkenylamine, a quaternated heterocyclic base or an aromatic amine) with a glycol, a polyethylene glycol, a polypropylene glycol, a vegetable or animal oil, fatty acid esters admixed with primary alcohols, fatty acid esters of mono- or poly-hydric alcohols or monohydric alcohol esters of dicarboxylic acids.  In an example, a lubricating composition consists of mineral lubricating oil and molybdic n-butyl xanthate.  For comparison purposes, a similar lubricating composition is described in which the xanthate is molybdic n-dodecyl xanthate.  Specifications 765,507 and 773,820 are referred to.

Class 89(3) A press for setting a pronged article 30, such as a hook or eye, on a garment 40, comprises a mandrel 24 arranged as a cantilever to support the garment, a die 25 on the mandrel for clinching the prongs of the article 30, a tool 8 arranged to support the article 30 and to be movable towards and away from the die, and a support 29 for the mandrel movable from a first position clear of the mandrel to a second position to support the mandrel. The support 29 is carried by an arm 27 pivoted at 28 and connected to the treadle mechanism which operates the plunger 4 which carries the tool 8. As the plunger 4 descends to clinch the article 30 to the garment the arm 27 moves the support 29 from the first position, shown in broken lines to the second position, shown in full lines. After the completion of the clinching operation and as the plunger 4 is lifted, the arm 27 returns the support 29 to the position shown in broken lines. The tool 8, which may be as described in Specification 889,007, automatically disengages from the article 30 when the plunger moves upwardly. A stay plate having apertures to receive the prongs of the article 30 is received by the die 25. Specifications 752,898, 756,553 and 799,173 also are referred to. Reference has been directed by the Comptroller to Specification 788,480.

Sheet glass is drawn out to a thinner sheet by progressing a continuous, fire-polished sheet 1 of uniform thickness over the surface 5 of a molten metal bath 2 while maintaining a non- oxidizing atmosphere 6 over the bath, re-heating as at 7 the moving sheet over a transverselyextending strip-like zone at a position where the viscosity exceeds 10<9> C.G.S. units and such that the marginal edges 13 of the sheet are excluded from the re-heating so as to retain substantially the initial viscosity and the strip is raised above softening temperature whereby the viscosity thereof is less than 10<7> C.G.S. units, drawing the strip horizontally in contact with the molten metal bath in the direction of the longitudinal axis of the initial continuous sheet to produce a continuous sheet 9 of uniform thickness less than that of the initial sheet save at the excluded edge 13, which are of substantially the original thickness, and two intermediate portions 14 of narrow width whereat the thickness varies, progressively cooling the sheet 9 on the surface of the molten metal bath in the non-oxidizing atmosphere to re-establish thermal homogeneity throughout the width of the sheet 9, and passing the sheet 9 into a tunnel kiln with horizontal carrying rolls to cool the sheet slowly. As shown in Fig. 3b, the re-heating is by tubes 16 of ceramic material carrying coils 17 of resistance wire extending from inwardly of the edges 13 of the sheet 1. Screens 18 may also be used to shield the edges 13 from the heating. As shown in Fig. 4a a heating plate 19 forms the base of a trough 22 of refractory material set into the superstructure 4 and covered by a refractory slab 23 with two outlet openings 24 and a central opening for a burner 20 fed by a gas-air mixture from two pipes 21.

Abstract: 364,817. Electrically rewinding spring motors. HORSTMANN GEAR CO., Ltd., HORSTMANN, A., and HORSTMANN, B. G., Newbridge Works, Bath. Dec. 22, 1930, No. 38535. [Class 139.] In automatic rewinding apparatus for spring or weight motors two members, A and B, are normally pressed together but may be moved relatively to one another to close contacts 3 for the rewinding electromotor, and the winding barrel and arbor actuate means for causing this relative movement. Members A and B are coaxial, B carrying a starwheel 17 and pin 13 and A having a cam notch 12, star-wheel 16 and extension 11 operating the contacts 3. As the barrel 1 rotates, driving the clock, a pin 4 on it rotates star-wheel 17 so that pin 13 is forced out of notch 12. As member B is pivoted at 15 in the frame 14, this moves member A axially against spring 8 so that projection 11 closes contacts 3, whereby the electromotor rotates the winding arbor and the wheel 2 thereon. A pin 5 on wheel 2 thereupon rotates starwheel 16 in the same direction as wheel 17 was moved so that notch 12 catches up pin 13 and contacts 3 open. When member A is in the lower position, as shown in Fig. 2, the wheel 16 is locked by a lug 20 on the frame plate 9. If, when contacts 3 close, there is no current then pin 4 moves wheel 17 and pin 13 onwards step by step (the barrel 1 rotating once a day) until pin 13 after nearly a full rotation meets a pin 21 in member A. This prevents pin 13 from re-entering notch 12 except by rotation of member A.
