Title: Improvements in, or relating to, electric switches
IPC: H01H21/04
Filed: 1923-08-27
Abstract: 225,602. Preston, W., (trading as Sanders & Co., W.). Aug. 27, 1923. Switches, quickbreak. - Ironclad switches, with pivoted knife-blade contacts operated by an internal stirrup or crank having an external handle and journaled in the casing coaxially with the knife-blades, are operated by the engagement of the transverse portion of the stirrup or crank with the ends of the knife blades remote from the pivots, the engagementbeing such as to permit some free movement longitudinal of the blades and thereby allow for any want of alignment between the axes of the operating and contact members. As shown in Figs. 1 and 4 applied to a two-way switch with two similar superimposed and spring-connected blades each of which serves in turn as the spark-taking blade as described in Specification 224,630, the transverse member g of the stirrup is covered by an insulating tube on which metal collars i are arranged and held in place by insulating spacing collars. In the case of single switch blades, a U-shaped recess in the free end of the blades embraces the metal collar allowing free driving movement. In the case of duplicate blades, Fig. 4, one half of the U-shaped recess f is formed in one blade and the other half in the other blade. A spring ball q in the handle co-operating with a recess in the casing affords a semi-lock in the intermediate off position.

Filed: 1927-08-18
Abstract: 306,561. Hornsey, J. W. Aug. 18, 1927. No Patent granted (Sealing fee not paid)- Rotary furnaces; charging and discharging.-In the direct reduction of iron in rotary furnace apparatus ore is passed through a rotary preheater 8 and delivered to a rotary reducing chamber 14 in which combustion is maintained under such conditions that the charge is kept from detrimental contact with the combustion air. The charge is supplied by a screw conveyer 9, which terminates short of the end of the feed conduit 10 so that the entering ore forms a seal and the preheating is effected by the waste gases from the reducing drum 14 supplemented by fuel and air supplied through nozzles 15, 17. A reducing agent, preferably coal, is fed on to the charge in the reducing drum through a pipe 18, and at the lower end of this drum is a burner 20 consisting of a pipe 21, through which powdered fuel together with, say, 25 per cent of the air necessary for combustion is delivered, and a. centrally-placed nozzle 22 for the remainder of the air. Beyond the delivery end of the nozzle 22 the pipe 21 is formed with a Venturi contraction 24. The fuel mixture is delivered at a pressure of about two ounces, and the air at about forty pound per square inch. By delivery the bulk of the air centrally through the fuel, reducing conditions are maintained in the outer part of the flame, and re-oxidation of the reduced ore is prevented. The burner is situated near the wall of the drum at a point above the middle of the inclined surface of the ore bed as shown in Fig. 2. The reduced ore passes to a drum 26 cooled externally by water from a pipe 27, and is discharged through a perforated portion 29 on to a self-sealing screw conveyer 31. After discharge the metal may be magnetically separated from the gangue. Large pieces of foreign matter, such as dislodged firebricks, pass over the perforated portion 29 of the drum and are discharged through the door 34. Sealing devices 12 are provided to prevent entry of air between the rotary drums and their end casings. Specification 284,040, [Class 72, Iron &c.], is. referred to.

Abstract: 999,560. Pulse radar. GENERAL ELECTRIC CO. Ltd. July 11, 1957 [July 18, 1956], No. 22311/56. Heading H4D. In a pulse radar system, which irradiates simultaneously on two radio frequency channels, elimination of interference signals, including jamming which occur on one channel at one time, is effected by means of an arrangement of adding and subtracting circuits which combine the signals in the two channels so as to leave only the echo signals. The signals in the two channels are added and subtracted to form, respectively, two further waveforms, the pulses of the latter being of one polarity after passage through a phase splitter. The latter are then subtracted to form a third waveform consisting only of the echo signals. The radar system consists of two separate magnetrons which feed the aerial through separate bandpass filters, to ensure that the radio frequency channels are different. For continuous wave interference, the received wave is converted into pulses of duration equal to the operative interval of the receiver.
