Class 75(iii) In a flame safety lamp for gas testing in mines including a base 1 lockable to the flame proof upper part of the lamp, the base is divided into two compartments 3, 4, one of which 3 serves as a fuel reservoir while the other 4 constitutes a pocket for the reception of a removable sealed casing 6 containing an electric spark generator for igniting the lamp operable by a handle 16 projecting through the wall of the casing in gas tight manner, and the sealed casing is retained in the compartment 4 by screws 7 the heads of which are covered by the upper part of the lamp. The screws 7 pass through holes in the base and engage blind holes in the casing. A pillar 9 carrying an electrode 10 passes through a sleeve 9a in the base and screws into the generator casing 6 to connect with a contact sunk below the top of the casing. A wick 12 containing one ,or more longitudinal metal threads is mounted in a tube 11 located close to the electrode 10 to form a spark gap therewith.. The wick is adjusted by a spindle 13 extending through a tube 14 extending through the fuel reservoir 3 to the bottom thereof, a knob on the end of the spindle being housed in a recessed part 15 of the reservoir bottom. The spark generator is preferably a magneto. Specification 656,375 is referred to.

Filed: 1971-07-02
Abstract: 1358091 Transistor detector circuits RCA CORPORATION 2 July 1971 [6 July 1970] 31036/71 Heading H3T A demodulator comprises first and second terminals to which amplitude modulated and reference carrier signals are applied, an amplifier connected to the first terminal, a charge storage means, and a transistor with base electrode connected to the first terminal, collector connected to the output terminal of the amplifier, and emitter connected to the charge storage means. In principle, amplitude modulated signal is fed from terminal 16, Fig. 1 over amplifier 6 to switch 8, comprising a transistor, and thence to charge storage means comprising capacitor 10, the switch 8 being periodically closed by pulses derived from peak detector 4 coupled to terminal 12 to which the reference carrier is supplied. In an embodiment the switch 8, Fig. 2, comprises a double-emitter transistor, amplitude modulated signals being applied to the collector 172 and one emitter 74, which are strapped together, from amplifier 6, which is provided with negative feedback by means of resistor 180. The output is taken from the second emitter 76, while gating pulses are applied to the base: these pulses are derived from unmodulated carrier by means of a peak detector comprising transistor 28, having a diode 38 connected in its emitter circuit. The pulses are amplified before application to the base of .switching transistor 8 by means of a cascade amplifier comprising transistors 46, 64. A single emitter transistor may alternatively be used as the switch 8. The specification also describes a modification comprising a full-wave demodulator (Fig. 4, not shown) and a further modification comprising a full-wave average level demodulator (Fig. 5, not shown).

Abstract: 1293868 Variable area jet propulsion nozzles SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 30 June 1970 [3 July 1969] 31562/70 Heading F1J The invention relates to a variable area jet propulsion nozzle, the assembly comprising an outer casing 2 and a jet nozzle 1 disposed therein so as to define an annular flow passage 6 therebetween, the nozzle comprising a series of controlled flaps 9 with follower flaps 109 therebetween. The downstream end 7 of the fixed jet pipe is shown and is supported within the casing 2 by means of a series of triangular-shaped members 10 pivotally connected to the jet pipe at 11 and to the casing at 12, the members being apertured for flow of air. A support member in the form of a hollow ring 15 is also mounted within the casing 2 by means of triangular-shaped members 18  which are pivotally connected to the ring 15 and to the casing at the point 12. Bracket members 16 are secured at spaced intervals around the ring 15, the members 18 being pivotally connected to adjacent brackets 16 at 17a. The ring 15 surrounds the assembly of nozzle flaps 9 and 109. A link member 19 is pivotally connected at one end to adjacent brackets 16 by pivot pins 17b and at the other end to the piston-rod 21 of an actuator 22, the cylinder of the actuator being pivotally connected to the casing 2 at point 23. The link member 19 is also connected at this other end to a link 25 which in turn is pivotally connected at 26 to the forward end of a controlled flap 9. A further link member 27 is pivotally connected to adjacent brackets 16 at points 17d and to the downstream end of the controlled flap 9 at point 28. The piston-rod 29 of a second actuator 30 is also pivotally connected to the flap 9 at the point 28. Further links 37 are pivotally connected to the brackets 16 at the points 17a, the links 37 being disposed between adjacent links 19 but not in the same plane, the links 37 being connected to the links 19 by links 38 there being knuckle joints at the ends of the pivot pins. Similar linkages 47, 48 are associated with the actuators 30, the object of these linkages being to synchronize movement of the controlled flaps. The flaps may be disposed to constitute either a convergent nozzle or a convergent-divergent nozzle. Auxiliary flaps 33 are pivotally mounted on the fixed jet pipe at 34 and bear against the forward ends of the controlled flaps 9 at their downstream ends 33b. Further flaps 133 are disposed between the flaps 33 and bear against the upstream ends of the follower flaps 109. The follower flaps 109 are retained within recesses formed at the edges of the controlled flaps by gas pressure within the nozzle.

Title: Improvements in and relating to the production of acetyl acetone
Inventor: HAUGHTON CHARLES OSBURNE
IPC: C07C45/84
Filed: 1957-10-10
Abstract: <PICT:0838142/III/1> Acetyl acetone is recovered from a reaction mixture containing at least acetic acid and acetic anhydride in addition to the acetyl acetone by adding water to the reaction mixture, heating to distil an azeotrope of acetyl acetone and water, allowing the condensed azeotrope to separate into two layers, and separating off the upper layer rich in acetyl acetone and distilling it to produce substantially pure acetyl acetone.  The reaction mixture, which may have been first distilled to remove more volatile constituents, is fed by pipe 1 to a still 2, steam-heated to about 100 DEG  C., water is supplied by pipes 41, 411 and 5, and azeotrope vapour passes by line 6 and condenser 7 to a decanter 8 where two layers separate, the lower of which is about 84% water, and is returned by pipes 411 and 5 to still 2, while the upper layer, which is 97% acetyl acetone, passes by line 10 to a second still 11 steam-heated to about 140 DEG  C.  Azeotrope distils by line 13 into a condenser 14 and thence to a decanter 15 from which the two layers formed are led into stills 2 and 11 by lines 5 and 16.  Acetyl acetone is withdrawn from the still 11 by way of condenser 17 and aqueous acetic acid from still 2 by way of condenser 18. Specification 615,523 is referred to.

[Also in Group XIII] A header for a tubular heat exchanger is made by depressing an initially flat metal plate 19 on one side at least of a dividing line a-a, dividing the plate into two portions along the line a-a, placing the two portions together face to face and joining them around their edges e.g. by welding or soldering, thereby forming the fluid cavity within the header and also a tube receiving aperture extending from the fluid space to the edge of the header. Preferably and as shown two such depressions 20 are formed by stamping in the plate 19 one on each side of the line a-a and are interconnected by three channels 21. When after cutting the two plate portions are placed in abutment the depressions together form the cavity 25 within the header and each opposed pair of the channels 21 forms an aperture 26 communicating with the cavity and receiving a heat exchange tube 14. Locating projections 36 at the ends of the tubes 14 are received in grooves 35 (Fig. 3) formed at the junction of the plate portions by the opposed rounded edges of the channels 21 in the stamping.
