Filed: 1963-02-11
Abstract: 1,074,281. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 3, 1964 [Feb. 11, 1963; Oct. 18, 1963], Nos. 5579/63 and 41221/63. Heading G6C. In a fast fission reactor the coolant is water at supercritical pressure. The coolant inlet temperature is maintained at a high value to reduce the density of the coolant and hence also its moderating effect. The ceramic fuel is enriched in plutonium and may be dispersed in a cermet. Three series turbines are connected to the reactor coolant outlet and a reheater, also supplied directly from the reactor, is in circuit between the first and second turbines. The condensate from the third turbine flows through heaters supplied with steam from the turbines. The reactor pressure vessel is cylindrical and has double walls between which shielding water at supercritical pressure is circulated. The inner wall has a mild steel neutron shield lining, each fuel element has a hexagonal casing containing fuel pins sheathed in stainless steel or chromium and nickel. The fuel material is annular to provide a central void for the collection of fission product gases and is composed of uranium and plutonium oxides. Breeder elements are situated at the core periphery. Epithermal neutron absorbers may be incorporated in the fuel to counteract rises in reactivity due to core flooding.

Title: Improvements in or relating to time base circuits for cathode-ray oscillographs
IPC: G01R13/32
Filed: 1957-02-19
Abstract: 854,858. Saw-tooth generating circuits; cathoderay oscilloscopes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 19, 1957 [Feb. 22,1956], No. 5602/57. Classes 40(6) and 40(7). In a time base circuit for a cathode-ray oscillograph, the deflection velocity is increased when the instantaneous value of the displayed voltage or its time derivative exceeds a certain value. As shown, valves 1, 2, 3 constitute a free-running time base wherein the velocity is governed by the anode current of the charging valve 1 which is controlled by the variable resistor 9 or the bias source 10. The circuit is synchronized by a pulse derived from the display waveform (terminals 13) by a pulse generator 12 and applied to the suppressor of valve 3, At the end of each sweep the time base capacitor 4 is discharged through valve 2 which is regeneratively coupled to valve 3. When the input waveform exceeds a certain level, the device 14 (not described) increases the suppressor voltage of valve 1 thus accelerating the sweep. The device 14 may contain a differentiating circuit to enable the expansion to be initiated by excessive rate of change of input voltage. The output of device 14 may alternatively be fed to a separate high-speed time base generator, the output voltage of which is superposed on that of the first saw-tooth generator.

Title: Improvements in process and apparatus for metal distillation and recovery
IPC: C01G1/00
Filed: 1949-03-01
Abstract: <PICT:0660688/III/1> Metals having a boiling point between 400 DEG C-1,500 DEG C (e.g. arsenic, antimony, cadmium and zinc) are distilled in an induction furnace and the vapours oxidized.  The induction furnace 2 has an annular cavity 6 surrounding a core 9 and primary winding 8.  Vapour flows through the pipe 15 and is oxidized and collected in a bag house (not shown).  The character of the product is varied by varying the melting rate of the metal charge in melting pot 25 thus affecting the level in feed chamber 17 and varying the cross-sectional area of the metal in cavity 6 resulting in a varying heat output from furnace 2 and causing oxidation to be effected at varying temperatures.

Title: Hypodermic injection device
IPC: A61M5/20
Filed: 1973-02-07
Abstract: 1382941 Hypodermic injection device PHILIPS GLOEILAMPENFABRIEKEN NV 7 Feb 1973 [10 Feb 1972] 6039/73 Heading A5R A hypodermic injection device comprises a cartridge holder 104 containing an ampoule 135, a cannula 150, and a gun-type assembly 200 whereby a spring 138 advances the ampoule and inserts the cannula until arrested by a buffer sprang 210 interposed between the ampoule 135 and the nose of the cartridge holder 161. The gun spring 138 then operates a piston in the ampoule 135 to inject the medicament until the buffer spring 210 overcomes the gun spring 138 and retracts the cannula. An outer sleeve 100 contains a concentric sleeve 104 within which fits the cartridge assembly, comprising the ampoule 135 on which is mounted the cannula 150. The sleeve 104 has a tapered end 156 seated by a stopper 158 pierceable by the cannula. At its end supporting the cannula 150 the ampoule 135 has a cylindrical projection 86 surrounded by or forming an abutment Fig. 3 (not shown) for the buffer spring 210. The ampoule cylinder 136 is closed by a piston 148. An annular bead 160 on the inner wall of sleeve 104 retains the ampoule. A plunger 162 has a head 164 with several tabs 168 extending radially and engaging the rear end face of the ampoule. Plunger 162 is held inoperative by lugs 186 at the ends of springy detent arms, which lugs latch on to face 122 of an inner gunsleeve 101. The coil spring 138, concentric with the plunger body, is thereby compressed between the plunger head 164 and the end wall of sleeve 101. A safety pin 144 prevents inadvertent operation of the device. With a safety cap 142 removed, pressure of the tapered end 156 on the patient causes relative movement between sleeves 192 and 100, whereby a cam surface 198 cams the detent lugs 186 together, until they pass through opening 120 and allow spring 138 to advance the plunger 164. Initially, the plunger tabs 168 force the ampoule off the bead 160, so that the cannula 150 travels through the stopper and into the patient. Movement of the ampoule compresses the buffer spring 210 which stops the ampoule. The tabs 168 then deform to allow the plunger to continue and thus advance piston 148 in the ampoule, injecting the medicament. As the gun spring 138 extends its force diminishes until the spring 212 overcomes it and retracts the cannula slightly.
