Filed: 1938-02-19
Abstract: 513,522. Extracting iron. DUFFIELD, F. L. Feb. 19, 1938, No. 5293. Drawings to Specification. [Class 72] Iron is obtained from iron ore by charging a mixture of the ore and carbonaceous material into a furnace containing an already heated mass at a higher temperature than that of reduction and effecting the reduction of the ore in a solid state without the application of further external heat. The heated mass in the furnace may comprise the furnace lining and loose carbonaceous material. On completion of the reduction, the furnace may be again heated to melt the iron and slag which are run off and a fresh charge introduced. The process may be carried out in a single furnace or in two furnaces worked alternately, which may be mounted to oscillate, the reduction taking place in one while the heating and melting takes place in the other. The gases evolved during reduction in one furnace may be burnt in the other ; or if a single furnace is used, the gases may be collected and stored, and returned for combustion during the heating and melting period.

Title: Improvements in and relating to the manufacture of rubber
IPC: C08L7/00
Filed: 1931-02-20
Abstract: In the manufacture of vulcanized rubber sheeting or other articles containing a substantial proportion of light vegetable p  fillers, particularly the sheeting described in Specification 851/31, in which the vulcanization is effected with the application of heat and pressure, the sheeted or other formed mixing is subjected to precuring throughout its mass prior to the application of pressure, for the purpose of preventing sticking to the mould or press plates. Such precuring may be effected by exposing the formed rubber, in an unconfined condition, in a hot air chamber heated to from 150 DEG  to 250 DEG  F.  After vulcanization in a hot press, the sheet &c. may be cooled under pressure.  In an example a rubber mix comprising 120 parts of rubber (in part softened by preheating as described in Specification 368,902), 260 parts of ground cork, 29 parts of carbonate of magnesium, 20 parts of zinc oxide, 1 part of stearic acid, 6 parts of sulphur and 2 1/2 parts of piperidyl dithiocarbamate of piperidine, is brought to sheet form, precured in unconfined condition for one hour at 212 DEG  F. and subsequently cured in a hot press for three minutes.

Title: Improvements in or relating to voice operated relay circuits
IPC: H04B3/20
Filed: 1930-02-18
Abstract: 348,704. Two-way repeaters. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Mathes, R. C.; 171, Sagamore Road, Wyoming, New Jersey, U.S.A.) Feb. 18, 1930, No. 5466. Convention date, April 18, 1929. [Class 40 (iv).] A voice-operated relay circuit of the type employed in echosuppressing equipment, repeater circuits &c. of telephone systems is rendered non-responsive to noise currents, e.g. those set up in the telephone circuits by induction from power lines or other adjacent circuits. In the arrangement shown, a relay 28, adapted to open the shortcircuit across the transmission line, is operated only when two control circuits respectively responsive to the syllable and voice-frequency ranges are operative. The circuit responsive to voice frequency is designed to exclude the fundamental and harmonics of the source of interference. The voice operated equipment, bridged across the transmission path L ahead of a delay network 30, comprises a high impedance amplifier 1 and a band-pass filter 2 adapted to pass voice frequencies and supply two interference protection circuits X, Y in parallel. The circuit X comprises input transformer 3, detector 4, transformer 5, low-pass filter 6 having a cut off at or near the maximum syllable frequency, e.g. 25 cycles, and amplifierdetector 7 adapted to operate and control relay 8. The output circuit of detector 4 is tuned by condenser 31, 32 and coils 33 to the minimum syllable frequency so that only frequencies in the range 2 .. 25 are passed through the control circuit. The control circuit Y comprises detector D and a series of band-pass filters 10 .. 13 adapted to pass different ranges of voice frequencies but exclude the fundamental and harmonic interference frequencies. The amplifiers 15 and detectors 17 in the filter circuits control corresponding relays 18 .. 21 having series connected contacts in the circuit of relay 28 which normally is energized to short-circuit the trailsmission L. In operation part of the voice currents passing over the line is shunted through filter F, currents of syllable frequency operating relay 8 and voice currents operating according to the momentary frequency, one of the relays 18 .. 21 to cause de-energization of relay 28 and removal of the short-circuit across the line. Although one or other control circuit may be operated by interference currents such currents are rendered substantially ineffective on the common control circuit of voice-operated relay 28. Instead of the push-pull arrangement of amplifier-detector 7, a single amplifier-detector may be employed provided there is sufficient time-lag in the operation of relay 8 for each syllable. Specification 142,115, [Class 40 (iv), Telephones &c.], is referred to.
