Title: Improvements relating to machines for effecting straightening or other operations on metal tubes or bars
IPC: B21D7/06
Filed: 1942-09-11
Abstract: 560,009. Straightening bars or tubes. T.I. (GROUP SERVICES), Ltd., and EVANS, D. W. T. Sept. 11, 1942, No. 12855. [Class 83 (iv)] A machine for effecting straightening or analogous operations on tubes or bars of the kind having a,pair of spaced anvils on which the work is horizontally supported and acted upon on its upper side between the anvils by a movable part has in combination therewith a horizontally movable carrier a part at least of which may be raised to clear the. anvils during the horizontal movements. Loading and unloading of the work may thus be effected by mechanical means. A pair of anvils b provided with V or half-round recesses c are supported by rollers e in guideways f on a bed a and may be adjusted thereon by mechanism through a hand wheel g. A straightening tool k is carried by a hydraulic ram j. The work d is rolled from a deck on to rollers o on arms m which rest on springs n and are pivoted on slides t vertically movable on slides s, which are adjustably secured together by a bar q and are supported by rollers v, w on a fixed track bar r along which they may be moved to loading or unloading positions. The vertical movement of the slides is effected by racks and pinions, the pinions being slidable on a shaft 2. The shaft may be rotated by a pinion 6 and a rack 7 on a third slide secured to the bar q and also mounted on the track r, the rack being operated by the plunger 8 of an hydraulic cylinder 9. The rack 7 when it is moved upwards snaps over a catch 10 pressed forward by a spring 11 so as to hold the slides in raised position until the work is brought over the anvils. The catch is released by further raising the rack a short distance and then withdrawing the catch by a spring-controlled hand lever 12 and links 13. The work is lowered by gravity at a rate controlled by the plunger 8 until it is slightly above the anvils, where it can be rotated by the operator to detect parts requiring straightening. The movement of the work on to the anvils by the plunger during straightening is permitted by the yielding of the springs n. In another form the slides are movable horizontally on a track bar itself vertically moved either by a series of supports carrying racks and pinions on a shaft rotated by a pinion and rack from a hydraulic cylinder or by connecting the supports to hydraulic plungers. In another form a pair of tracks r<2> may be used on opposite sides of the anvils supporting arms m2 on springs 24. The vertical movements in this case may be effected -as in either of the previously described forms.

The cable 2 may be passed through or over part of the object to be protected (e.g. through a wheel of a protected vehicle) and the connector 6 inserted into a complementary connector 7 so as to complete the circuit 16 in such a way that if said one conductor is broken the alarm is given. As described, resistors 13, 14 may be included in series with some of the conductors of the cable 2 or may be replaced by printed resistive elements on a tape-like cable. The housing 1 may include means for rewinding the cable 2, provided with brushes so as to make connections to the conductors. The circuit 16 of otherwise unspecified form may be responsive to the resistance of the circuit so as to defeat attempts to bridge certain of the conductors of cable 2 before disconnecting same. The conductors of cable 2 may be colour coded or may be all the same colour and some of them may not be connected to the circuit 16 so as to confuse a potential thief.
Patent GB-560013-A (GB)
Title: Improvements in or relating to thermionic valve circuits
IPC: H03G3/26
Filed: 1942-09-12
Abstract: 560,013. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., HOUGHTON, L. W., and SCULLY, C. T. Sept. 12, 1942; No. 12884. [Class 40 (v)] An amplifier is blocked in the absence of signals to obtain muting of noise and interference at low level by providing the resistance element of a thermistor, or thermo-sensitive resistance in series in the cathode lead, so as to be traversed by the anode current and in the no signal condition to bias the valve nearly to cut-off point and to a lower steady value when signals of a predetermined level are received. The Figure shows an arrangement for muting or for volume expansion by using a thermistor of appropriate temperature co-efficient. The thermistor T has a 'negative' temperature co-efficient and is of such a value that, with the added series and shunt resistances X1, X2 if necessary, the cathode is maintained at a sufficient potential to block the valve with no signal. The valve is so arranged that some signal rectification occurs. An indirectly heated thermistor heated by part of the output signal current may be used. Fig. 2 (not shown), so that operation need not depend on rectification, or by the current in a control valve in a radio receiver or by a proportion of the output of a preceding A resistance or a second thermistor with appropriate temperature eoefficient may be connected in shunt to the valve and its load to accelerate the change in cathode potential.

Filed: 1929-04-26
Abstract: 334,500. Gr÷nwall, E. A,. A., and Nathorst, H. J. H. April 26, 1929. Shaft furnaces.-In a process for reducing iron and other ores by means of carbonaceous reducing agents, the combustible gases escaping at the upper portion of a shaft furnace are partly burnt with oxygen and blown back into the charge, a continual circulation being maintained. In a modification the escaping gases are treated for the removal of carbon dioxide, are partly burnt with oxygen, passed through coal to increase the content of carbon monoxide, and again partly burnt with a further quantity of oxygen before being blown back into the charge. The gases are led off through a pipe 4, Fig. 1, and the carbon dioxide removed by freezing or absorption and returned to the furnace 1 by a pipe 5. Oxygen is admitted by the pipes 11 and partial combustion takes place in the chamber 12, whence the gases are returned to the charge. A furnace particularly designed for the production of iron sponge according to the modification of the invention described above is shown in Fig. 3. The gases withdrawn from the furnace enter a recuperator 33, are led off by a pipe 35 and treated for removal of carbon dioxide; the gases returning to the recuperator by a pipe 34. A part of the gases is now burnt in a chamber 36 with oxygen admitted through a pipe 37 and is then passed through coal in a tower 38. The carburetted gases are mixed with the remainder of the gases in the chamber 39 and led to the chamber 41 where they are burnt with oxygen admitted through the pipes 40 before being led to the charge. Water cooled plates 31 for cooling the sponge and a feeding out device 32 are also provided.
