Title: Improvements in or relating to methods of manufacturing alloy p-n junctions in germanium
IPC: F16L37/52
Filed: 1956-07-18
Abstract: A method of making a PN junction comprises melting a donor or acceptor impurity on to a P or N type germanium body by heating to below 450 DEG C. in the presence of a halogen in elemental or combined form and subsequently heating to a higher temperature above 350 DEG C. at which temperature the vapour pressure of the halogen or halogen compound is at least 10 mm. of mercury.  In one example a transistor is made by applying small beads of indium to opposite sides of a 150m  thick disc of N type germanium, heating in a stream of dry hydrogen to 300 DEG C. and then for several seconds introducing hydrochloric acid into the stream so that the indium wets the germanium but does not readily dissolve it.  A base contact is simultaneously secured by tin solder.  Subsequently nitrogen containing a trace of oxygen is introduced and the temperature increased to 600 DEG C. so that alloy electrodes are formed and the hydrochloric acid evaporated.  Halogens or other halogen-hydrogen acids may be used instead of hydrochloric acid. In an alternative method the beads of indium are moistened in a saturated solution of pyridine hydrochloride in water before being applied to the germanium wafer, in which case the introduction of the hydrochloric acid is unnecessary.  Halogen hydrogen molecular complexes of organic compounds e.g. aniline chlorhydride, dimethylaniline chlorhydride, and guanidine chloride, or indium chloride may be used instead of pyridine hydrochloride for wetting the beads.

Abstract: 698,339. Aircraft landing lamps. HARLEY, M. C. Dec. 12, 1951 [Sept. 12, 1950], No. 22442/50. Class 75(iii) In a retractable aircraft landing lamp operated by an electric or hydraulic actuator d, having two mutually. telescopic members, in conjunction with limit switches or the like and a resilient connection f which effects resilient holding of the lamp in its retraction position, the actuator d embodies a connection g between one end and a fixed anchorage h or between the other end and the lamp housing b, the connection g being arranged to give way under a predetermined air pressure on the lamp when in an extended position thereby to allow the lamp to move back into retracted position irrespective of the operative setting of the actuator d. As shown the connection g is at the anchorage end of the actuator and comprises an arm pivoted about the fixed point h and having a recess k normally engaged by a roller m on one end of a spring-loaded pivoted lever n. The arm g has a disc portion j associated with adjustable spring-controlled friction discs q which control pivotal movement of the arm g when the latter is disengaged, under pressure, from roller m. The lamp b has a catch roller t to engage with a slight clearance w behind a remotely controlled latch member u when the lamp is in its retracted position. In operation, when the lamp is forced back by wind pressure, the actuator d is moved bodily, such movement being, controlled by the friction-controlled rotation of arm g. Movement of arm g may operate a warning lamp whereon the pilot operates the actuator d into the retracted position. Since the lamp is already retracted, such operation of the actuator causes return movement of the arm g into its normal position in engagement with roller m. Specification 627,946 is referred to.

Title: Improvements in and relating to fractional distillation
IPC: B01D3/14
Filed: 1964-05-29
Abstract: <PICT:1066342/C4-C5/1> In a method of separating a liquid mixture into fractions by distillation in a rectification system comprising bubble trays, provision being made for the independent control of the reflux ratio and the pressure at two or more sections of the system, the reflux ratio and pressure required for the separation are applied to the section where the composition of the mixture undergoing rectification is relatively constant from tray to tray in the section, and a lower reflux ratio and higher pressure are applied to the ends of the system where there is a relatively rapid change in composition from tray to tray. Thus the reflux ratio is highest and the pressure is lowest in the section where the separation is most difficult.  The method is particularly applicable to superfractionation, such as is required in the separation of ethylbenzene from a mixture with xylene isomers.  The rectification may be carried out in a system comprising two rectifying columns 1, 2, a pinch column 3 and a stripping column 4.  The liquid to be separated is pumped through line 74 and preheater 78 into column 3, which is heated by reboiler 68 and by the vapours conducted through line 40 from the head of column 4. The overhead vapour from column 3 passes to condenser 50.  Part of the condensate is pumped through valve 62 to the top tray of column 3, the remainder being pumped through valve 110 and line 104 to the reboiler 106 of column 2. Some of the liquid withdrawn from the base of column 2 passes to reboiler 106, and the remainder is pumped through line 52 to mix with the main reflux for column 3.  The overhead vapour from column 1 passes to condenser 12. Part of the condensate is refluxed through line 122 to the top tray of column 1, and the remainder is withdrawn from the system as overhead product.  Columns 1, 3 and 4 are provided with pressure-controllers 100, 64 and 36, respectively; and columns 1, 2 and 4 are operated at higher pressure than column 3. The bottoms product is withdrawn from the base of column 4.  In a modification of the system, the liquid passing from the base of column 1 to the top of column 2 flows in counter-current heat exchange with the vapour which has come from the head of column 2. The vapour is then compressed before being introduced into the base of column 1.  Part of the vapour from the head of column 3 is passed in heat exchange with the liquid being conducted from the base of column 2 to the top of column 3; the vapour is then compressed and introduced into the base of column 2.

Abstract: 1466624 Electronic timepieces HUGHES AIRCRAFT CO 20 May 1974 [29 May 1973] 22470/74 Heading G3T  An electronic watch Fig. 2, is arranged to continuously display hours and minutes on a liquid crystal digital display device e.g. liquid crystal or light emitting diodes, and to replace the hours and minutes display by the date or seconds display on the same display devices, upon demand. A.M. and P.M. are displayed by illuminated colon dots, and a light-emitting diode 27, Fig. 1, is provided to illuminate the display if liquid crystal type. Transmission gates 80, 82, 84, 86, 88, 90, 92 connect the outputs of the various seconds, minutes, hours and days BCD counters to input 74 of a de-coder 72 and are controlled by a multiplex driver 94, Other transmission gates (not shown) connect the counters to input lines 76, 78, 79 of the de-coder. A multi-plexing arrangement is used to restrict the number of de-coders required, the inputs and outputs of the de-coder 72 being multi-plexed. Normally, the driver 94 operates the transmission gates such that the lines 74, 76, 78, 79 receive the BCD digital code bit when for example the unit minutes counter 58 is connected thereto by the ON condition of transmission gates 84 etc. The de-coder 72 output commands the energization of the necessary lines for operation of the 7-bar segment display in the unit minutes display device 28. A demulti-plexer 98 receives the de-coder commands also digit select information from the multi-plex driver 94 which controls it so that the command information from the de-coder is properly distributed to respective memory driver devices 100, 102, 104 which continuously energize selected segments of the 7-bar segment display devices. To display seconds instead of minutes and hours, a push-button 40 is depressed and causes the multiplex driver 94 to turn ON transmission gates 80, 82 whereby the content of the seconds counters are displayed. Likewise, upon depression of a pushbutton 42 the driver 94 causes gates 90, 92 to pass the content of the days counters 66, 68 to the display devices 28, 30. A push-button 44 is used in conjunction with 40, 42 for setting the counters to give the correct time. The demulti-plexer is a switching device and in order that continuous power may be fed to each selected display segment, the memory drivers are provided. Reference has been directed by the Comptroller to Specification 1391396.
