Title: Regulated power supply
IPC: G05F1/573
Filed: 1959-05-04
Abstract: 920,254. Automatic voltage control; automatic regulation. HEWLETT-PACKARD CO. May 4, 1959 [May 26, 1958], No. 15272/69. Class 38 (4). In a regulated power supply a series regulating transistor is controlled by a transistor amplifier responsive to the difference between a fixed reference current and a current dependent on the output voltage. In an embodiment, the base current of a transistor 21, having the emitter and collector in series with a rectified supply 16 to terminals 24, 26, is controlled by an amplifier comprising common emitter connected directcoupled transistors 51, 52. The base of transistor 51 is connected through a current limiting resistor 53 to a junction 44, the base current being the difference between a constant reference current through resistors 42, 43 and a current, through a variable resistor 27, dependent on the load voltage across terminals 24, 26. The transistor amplifier is supplied from a control supply 31. Resistors 71, 72 are connected to apply a reverse bias to the bases of transistors 21, 52 to compensate for collector leakage current. A diode 68 prevents excessive voltage surges after the power is cut-off. The output current is limited when the voltage across a resistor 63, proportional to the output current, causes a current to flow through a diode 64 to apply a bias to the base of the transistor 52. The current limit is set by the variable resistor 63 and calibrated by the variable resistor 61. The constant reference current is derived by applying a constant voltage across resistors 42, 43. The voltage at the junction 44 is approximately equal to the voltage of terminal 24 due to the low emitter to base voltage of transistor 51. The voltage at the emitter of a transistor 48 is maintained constant by the transistor being connected as an emitter follower, the base voltage of which is dependent on a Zener diode 47 fed through a resistor 46. A resistor 49 reduces the collector voltage to reduce the dissipation of the transistor 48.

Title: Control apparatus in a data processing system
IPC: G06F9/30
Filed: 1966-04-06
Abstract: 1,139,181. Digital computer programme control. GENERAL ELECTRIC CO. 6 April, 1966 [6 April, 1965; 14 April, 1965], No. 15379/66. Heading G4A. In a data processing system instruction words are decoded and the instruction executed by a sequence of subroutines in a central processor 490, the particular subroutine in a sequence being determined by the state of W-register 470, and being controlled by signal generating means 486 co-operating with counter means 488. Each subroutine includes a " memory read " sequence and a " memory write " sequence. Initially the counter 488 is set to zero and a read sequence is performed. The clock is stopped to allow the memory to complete the read operation, and then a check is made on flip-flop RCK (not shown) which indicates whether the next sequence is to be a read or write sequence. If a write sequence, then the subroutine is continued; if a read sequence, the counter is reset and a new subroutine, determined by the W-register 470, begins. If during a sequence of instruction words, data is to be transferred between the memory and peripheral subsystems, an R- register 758, which is normally at ZERO is set to ONE and emits a signal to a gate 483 to inhibit the output signals of the W-register and thus interrupt execution of the instruction at present under operation. Further subroutines corresponding to the state of R- register are then performed to transfer the required data, R-register being then reset to zero to enable gate 483 so that execution of the instruction may be continued.

Title: Tire supporting apparatus
IPC: G01M17/02
Filed: 1958-05-15
Abstract: 865,371. Tyre supporting apparatus. SMYSER, J. A. May 15, 1958 [May 21, 1957], No. 15626/58. Class 144 (1). An apparatus for supporting a tubeless tyre to be worked on, such as by buffing, comprises an expansible rim 50 of arcuate channel-section segments 51 sleeved by a rubber ring 70 which covers each segment channel base 52 between the channel side flanges 63 and resiliently urges the segments to contracted positions circumferentially abutting each other coaxial with a support shaft 21, the segments being supported on the shaft 21 by means for moving the segments radially outwardly to expand the band 70 into sealing engagement with the beads of the tyre, and the band having an inflating valve 75-77 for inflation of the tyre to force the tyre beads against the segment side flanges 63. 'As shown the shaft 21 carrying a rotatable sleeve 25 is supported on a frame 20 to extend adjustably adjacent the work-machine. The sleeve 25 is oppositely screw-threaded at its ends to engage correspondingly threaded collars 35, and carries a hand wheel 92 at its free end. Each segment 51 is radially guided by a rod 45 slidable in a tubular spoke 43 radiating from a hub 40 axially located on the sleeve 25. Additionally each segment is pivotally connected to the collars 35 by a pair of rigid links 59 so that on rotation of the sleeve 25 by the hand wheel 92, the collars 35 are oppositely displaced to move the segments radially inwardly or outwardly to contracted or expanded positions. To prevent pinching of the band 70 and to hold the band circular in expanded position, resiliently flexible steel plates 80 are bonded to the inner periphery of the band to bridge the gaps between the segments. In use the tyre is readily seated on the segments in their contracted position. In an alternative arrangement for expanding the segments, the hub 40 and rods 45 are omitted, one collar 35 is anchored to the sleeve 25, which is unthreaded, and the other collar 35 is slidable towards the anchored collar by an hydraulic piston coaxially surrounding the sleeve 25, retraction of the movable collar being effected on release of the hydraulic pressure by the resilience of the band 70.
Patent GB-356107-A (GB)
Title: Process of making styrol
IPC: C07C1/30
Filed: 1930-05-21
Abstract: Styrol suitable for direct polymerization is obtained by treating ethylbenzene with chlorine at temperatures of 70-120 DEG  C. to form chlorethylbenzene, fractionating the mixture to drive off unchanged ethylbenzene, heating the residue with an organic base such as pyridine at temperatures of about 100-230 DEG  C. at not more than atmospheric pressure, and recovering styrol from the reaction product.  The chlorination of the ethylbenzene to give a mixture of a - and b -chlorethylbenzene, the latter predominating, may be carried out at 90-100 DEG  C., preferably in light, 8-25 parts of chlorine being absorbed for every 100 parts of ethylbenzene.  The chlorinated product is fractionated, and the fraction coming over below 155 DEG C. is regarded as unchanged ethylbenzene and returned to the process. The residue is heated under a reflux condenser for about 3 hours with excess of pyridine, preferably at 180-220 DEG  C.  When the reaction is completed, the pyridine hydrochloride formed can be drawn off from the bottom of the kettle as a liquid, or may be solidified by cooling, the residual liquid being drawn off, acidified with hydrochloric acid, and steam distilled.  The distillate is dried and fractionated, yielding 45-70 per cent styrol in the fraction coming over below 160 DEG  C.  Some hydrocarbon boiling over 160 DEG  C. is obtained, which may be accumulated and subjected to a second treatment with pyridine.  Alternatively the entire mixture obtained by refluxing may be acidified with hydrochloric acid and then distilled.  All the pyridine then remains in the steam still as hydrochloride, the styrol in the distillate being further purified as above.  Instead of pyridine, organic bases such as quinoline, dimethylaniline, or dibenzylamine may be employed.  Examples are given.  Specification 298,152, [Class 2 (iii), Dyes &c], is referred to.

Title: Improvements in or relating to fuel tanks
Inventor: SMEDLEY FREDERICK EDWARD SAMUE
IPC: B64D37/10
Filed: 1948-06-10
Abstract: 653,667. Venting tanks. ROLLS-ROYCE, Ltd. June 10 1948, No. 15716. [Class 21] [Also in Group XXIX] To prevent the fuel volatilizing at high rates of climb in an aircraft fuel installation the tank is vented through a valve which is moved or loaded in the sense of closure by means responsive to the rate of change of ambient atmospheric pressure, so that, at least when a predetermined rate of decrease in ambient pressure occurs, the valve is closed and the fuel tank becomes pressurized relative to the ambient atmosphere to an extent at least in part dependent on said rate of decrease in ambient atmospheric pressure. In one form. an expansible capsule 7 carries at one end a disc valve 5, which is arranged between the vent line 2 and interior of the tank 1, the interior of the capsule con-. necting via an orifice 8 with an air chamber 9 vented to atmosphere through a restricted bleed orifice 10. In level flight the pressure in the vent line is the same as that within the air chamber 9, and therefore the capsule 7 and the valve 5 is held open. At high rates of climb the bleed orifice 10 ensures that the rate of fall of pressure within the air chamber is less than the rate of fall of atmospheric pressure within the vent line 2 so that the capsule expands, closes the valve 5 and pressurizes the tank. On assuming level flight, the air in the chamber 9 leaks out through the bleed orifice 10, the valve 5 opens and the tank decompresses. A spring-loaded relief valve 13 prevents pressure in the tank reaching a dangerous value in a sustained climb and a valve 16 may be fitted within the relief valve 13 to prevent an excessive negative pressure developing within the tank. In a modification a spring is interposed between the capsule 7 and valve 5 so that the tank is pressurized during level flight, the degree of pressurization being increased during a climb by the capsule. If the device is used in conjunction with nitrogen purged tanks, the restricted orifice 10 is connected to the fuel-tank vent-line upstream of the nitrogen vent outlet valve.
