Abstract: 1,263,174. Controlled rectifiers. WESTING- HOUSE BRAKE ENGLISH ELECTRIC SEMI-CONDUCTORS Ltd. 21 May, 1970 [11 June, 1969], No. 29713/69. Heading H1K. The basic features of the SCR shown are the presence of main emitter 4 with a partly shorted junction, of auxiliary emitter 18, and of a conductive zone 7 in contact with the base region 3 and between but spaced from the emitters. The conductive zone, by by-passing parts of the base regions, provides paths of equal electrical length between the auxiliary emitter and adjacent parts of the main emitter; this allows rapid transfer of turnover between the two. In the illustrated embodiment the auxiliary emitter junction is also part-shorted by the electrode 9 and the annular main emitter has additional shorts 16 at locations on its outer junction peri= phery. An extra conductive zone 17, conductively connected to the first, is also provided. To fire the rectifier a pulse source in series with a limiting resistor is connected between the emitters so as to forward bias the auxiliary emitter, the source being by-passed by a diode to allow continuation of auxiliary emitter current after firing has been initiated. To prevent the auxiliary emitter from tending to turn off by going into reverse bias once the main emitter has fired, a diode (which may be mounted on the conductive zone) may be connected between the auxiliary emitter and the conductive zone. Fig. 1 (not shown) shows how the main emitter may be shaped to increase that part of its periphery adjacent the auxiliary emitter and shows the necessary modification to the shape of the conductive zone to enable it to fulfil its function.

Abstract: 408,893. Ping couplings. HINLEY, S. D., ALEXANDER, G. H., 22, Lombard Street, Birmingham, and CHECKLEY, G., Woodlands, Gunners Lane, Rubery, near Birmingham. Oct. 27, 1933, No. 29831. [Class 38 (i).] A coupling of the type having alternative sets of pins 5, 10 mounted on a reversible base 2 having a lateral entry for leads 18, is provided with an adjustment for both sets of pins by passing the interconnecting shanks 6 through elongated holes 7 in the base 2. The spacing of the sets of pins may be different, those of one set being mounted on bosses 12, flat-sided to fit guiding slots 11, the other pins being screwed directly to the shanks 6 and entering a series of seatings 14 to give a positive location. A cap 46 covers the pins not in use, the fixing screw 47 for which may be inverted so that it is not accessible when the plug is in the socket. The leads are anchored by a plate fitting a recess in the base 2 and wedging the leads apart in the recess. A fuse 24, Fig. 7, may be introduced in one or both poles, one end of the fuse fitting into a cup 27 on a terminal 28 for the lead, and the other end engaging a contact 34 attached to a plate 35 lining the bottom of the slot 11. A switch 37 may also be incorporated comprising fixed contacts 40, 41 into which moves a sliding bridging contact 38 associated with a resilient pivoted arm 45 to give a snap action. An adapter having sockets at one end to fit the pins and a plug at the other end to fit a lampholder may be used in conjunction with the device. The invention may also be used in a branching connector 54, Fig. 11. The two sets of pins 65, 67 project oppositely from the body 57 of the connector through curved slots 69 which may be associated with locating seatings 70, 71. The pins of one pole are connected together by an arm 64 pivoted at 63 to a strip 61 that connects with one of each pair of sockets 58, 59.

Title: Improvements in temperature detectors or regulators
IPC: G05D23/02
Filed: 1952-11-26
Abstract: 743,784. Thermal switches. GRAVINER MANUFACTURING CO., Ltd., MATHISEN, A., WILKINSON SWORD CO., Ltd., and GRIFFITHS, R. Nov. 17, 1953 [Nov. 26, 1952], No.. 29900/52. Class 38(5) [Also in Group XIII] In a temperature regulator or detector, e.g. for indicating fire in an aircraft, the thermal expansion of a first member 10 varies the force applied to a second member which has a main element 14a of negligible thermal expansion and resilient elements 14b, 14c which tend to straighten the main element as the first member expands but which are free themselves to expand thermally without varying the force they apply to the main element 14a. The main element may be one strip 14a but, as shown, there are two such bowed strips of low expansion material such as nickelcobalt-iron alloy, secured near the ends of a surrounding tubular, alloy steel barrel 10 so that as the barrel expands compression of the strips is relieved and their middle portions, which may carry electrical contacts 19, close together. To avoid both false operation on a sudden rise in temperature when the strips remain relatively unheated and the subsequent cancelling of the operation as the strips slowly heat and expand slightly, resiliency tending to straighten the strips is imparted by elements 14b, 14c since the low expansion of the strips has not resilient properties. Two leaf springs 14b are mounted, one at each end, bearing as cantilevers on the outside of each bowed strip and a central leaf spring 14c is mounted on the inside of each bowed strip. The central leaf springs 14c have lugs 14d at their ends bent along the edge of the strips and are also located by means of the contacts 19 and their mica insulation 25. The lugs 14d may be replaced by bumps raised on the bowed strips 14a to engage dimples in the leaf springs 14b, 14c. Wires 23 connect the contacts 19 to studs 22 in a steel casing 11 which also contains a spigot 11a in which a flanged carrier 15 for the bowed assembly is slidably mounted to obviate damage caused by excess expansion of the barrel 10 after the contacts come together. The other end of the spring assembly is secured in a non- rotating carrier 16 which is raised or lowered, for adjustment, by rotation of a sleeve nut 17.

Abstract: <PICT:0485985/III/1> In adsorbers for benzole recovery &c. having a heating and cooling coil arranged within the adsorbent, steam is used as the heating medium and the cooled condensate of this steam is used as cooling medium, thereby preventing corrosion of the coil.  The coil 8 leads from the bottom of a chamber 6 situated in the upper part of the adsorber and having a steam inlet 7, and terminates in two branches 9, 13 terminating respectively at the top and bottom of a condenser 12.  In the heating period steam is admitted at 7, expelling the water already in chamber 6, and passes by the pipe 9 and inspection glass 11 to the condenser.  When flushing of the adsorbent is completed and gas is again admitted by the pipe 2, valves 7 and 10 are closed.  The cooling action of the gas causes condensation in chamber 6, whereupon the cooled condensate in 12 is sucked back through the check valve 14 into the coil 8 and chamber 6.
