Title: Improvements in igniting devices in internal combustion engines
IPC: F02B3/00
Filed: 1930-09-23
Abstract: 355,983. Flame igniters ; starting. FUEL CONVERSION APPLIANCES PROPRIETARY, Ltd. and ROBERTSON, E. C., 366, Bourke -Street, Melbourne, Australia. Sept. 23, 1930, No. 28448. [Classes 7 (iv) and 7 (v).] A main charge of air and crude oil is ignited by a flame produced by the ignition of an auxiliary charge of mixture containing light fuel, in a chamber connected to the cylinder by a passage-way which is closed by a valve during the induction stroke of the engine. A sparking plug is located at 9 in a chamber 8 into which the auxiliary charge is drawn through a passage 7, the chamber being connected to the cylinder by a passage 13 and orifices 15. A valve 12 seats at 11 on the end of the passage 13 during the induction stroke, when the combustion products are withdrawn from the chamber 8 through the orifices 15 and a fresh light fuel charge is induced. During compression, the valve closes on a seat 23 cutting off the light fuel mixture. At starting and when idling, the valve 11 is held midway between the seats by a collar held against the valve stem by a lever 25 actuated by a Bowden wire, and the engine then runs on light fuel mixture. The orifices 15 may be formed by grooves in the valve seat.

Title: Method of and apparatus for reproducing sound films
IPC: G03B31/00
Filed: 1929-09-19
Abstract: 341,845. Sound-reproducing apparatus associated with kinematographs. BLUM, C. R., 54, Badenschestrasse, Sch÷ne. berg, Berlin. Sept. 19, 1929, No. 28475. [Class 40 (ii).] A motion-picture projector, a sound-reproducing apparatus and a rhythm-band apparatus have their driving motors interconnected and the rhythmband apparatus is driven synchronously with the sound record so that by observing the rhythm-band and the projected picture or the film a visible indication is given of the relative positions of the picture film and the sound record. As shown in Fig. 3, a projector 8 is driven by a motor 7 the speed of which can be controlled by a regulating resistance 9<1>. Motors 13, 15 driving the rhythm-band 4 and a sound reproducer 14 are arranged in parallel and are driven in synchronism, the circuit for the motors 13, 15 being connected to a battery 11 and a make-and-break device 10 driven by the projector 8 or motor 7. The sound reproducer may have two turntables 36, 37, Fig. 4, driven by a motor 42. The turntables are raised to engage the records with the reproducers by levers 43, 44, which are controlled by electromagnets 45, 46. Each turn, table spindle 40, 41 carries a contact 55, 56- adapted, when the turntable is raised, to engage a fixed contact 57, 58, once per revolution and thus energize a magnet 53, Fig. 7. The latter controls an armature 52 to permit a ratchet wheel 51 to move a distance of one tooth. Each ratchet wheel spindle 50 has an indicator finger 49, 61, Fig. 8, movable over a graduated dial 47, 48. The fingers 49, 61 thus indicate the number of played-out grooves of the records. The fingers 49, 61, coact with pairs of contacts 59, 60, in the circuits of the electromagnets 45, 46, so that when the record on one turntable has been played that turntable is lowered and the other turntable is raised. The contacts 59, 60, may be arranged so that for a short period prior to changing from one record to another both records are being played together. If the kinematograph film should break, the apparatus is stopped and the repaired film is threaded through the film gate. The contact device 10, Fig. 3, is then thrown out of the motor circuits and a hand contact device 63, Fig. 5, substituted. Operation of the device 63 causes the rhythm-band apparatus and the sound reproducer to move together while the kinematograph film is stationary until the rhythm-band and kinematograph film are in corresponding positions. To facilitate adjustment the rhythm-band and the film may have corresponding markings. A device such as 63 is more fully described in Specification 339,941. Specification 13235/09, [Class 40 (ii), Phonographs &c.], also is referred to.

Title: Improvements in the manufacture of alloys and articles produced therefrom
IPC: C22F1/00
Filed: 1924-12-03
Abstract: 248,458. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 3, 1924. Drawings to Specification. Modifying physical characteristics of metals.- Alloys are produced by combining elementary constituents in such proportions and subjecting them to such treatment that a supersaturated solid solution is produced, the treatment comprising heating, quenching and ageing. The alloy is heated to a temperautre below the eutectic fusing temperature of the constituents and the heating is continued until a substantially solid solution is formed; the alloy is quenched preferably at room temperature and aged at a temperature below the temperature of recrystallization of the alloy. For example, a leadantimony alloy is produced by combining 2.5 parts of antimony and 97.5 parts of lead and heating the mixture to about 240‹ C. for 72 hours, the material then being quenched in water to 100‹ C. or to room temperature and aged at room temperature. The treatment is also applied to lead-tin and aluminium-zinc alloys and also lead-antimony alloys containing also a small amount of copper. For example, a mixture of 38 per cent of zinc and 62 per cent of aluminium is heated at about 440‹ C. for about 7 hours, quenched and aged, the latter operation preferably at a temperature below 100‹ C. The leadantimony above referred to may be cast in the form of an ingot, allowed to solidify, heated until a partial solid solution is formed and then quenched and aged, both at a temperature below 100‹ C. The ingot may, however, after heating be rolled into a. flat sheet and quenched, articles such as storage battery grids being then stamped from the sheet and aged. The stamping may be done before quenching. In another form, the lead-antimony alloy previously referred to may be heated at 240‹ C. and maintained at this temperature whilst being rolled or struck with a hammer, the desired solid solution being formed so quickly that, as soon as the work has been completed, the article may be quenched.

Title: Improvements in electrodeposition of chromium
Inventor: SUCH TONY EUGENE
IPC: C25D3/04
Filed: 1963-07-24
Abstract: Micro-cracked chromium is cathodically deposited from an aqueous solution containing 100 to 200 g/l of chromic acid and, based on the chromic acid content, 0.1 to 0.3% sulphate ion and 1.5 to 4% silicofluoride ion, the silicofluoride ion content being greater than 2% if the sulphate ion content is less than 0.2%. Preferably the solution contains less than 8 g/l of metallic impurities such as iron, zinc or copper, e.g. resulting from dissolutio of articles to be plated. If a larger amount of impurities is present the solution should contain more than 0.25% of sulphate ion and more than 2% of silicofluoride ion.  The bath may contain strontium sulphate in excess of its bath solubility and an innocuous strontium salt such as the chromate to suppress the solubility of the strontium sulphate and maintain the desired sulphate ion concentration.  Typically the chromium is deposited at a current density of 160 amps/ft2 on steel panels which have been previously electroplated with bright nickel, the bath being used at 112 DEG F.  Reference is made to liquid concentrates for making up the baths by mere dilution and to solid mixtures for dissolution to form the baths.
