Title: Apparatus for use in semi-automatic well testing
IPC: E21B47/10
Filed: 1964-08-18
Abstract: 1,019,177. Delivering measured quantities of liquid. TEXAS PETROLEUM CO. Aug. 18, 1964 [Aug. 26, 1963], No. 33771/64. Heading B8N. [Also in Division El] Apparatus for testing the production of individual wells in a group of wells in a predetermined sequence comprises timing means for controlling the switching from one well to the next after a predetermined time, and overriding means for controlling the switching of one well to the next if a predetermined quantity of production flows from a well under test before the predetermined time. Production from the wells flows through lines 11, ... 14 having pneumatically controlled valves 24,.. .27, the arrangement being that pressure is applied to one valve to direct production of its well through a line 29 to a test separator 30 whilst the production from the remaining wells flows through a line 17 to a production separator. The operating pressure is directed to the valves in turn by a distributer 34 rotated by a pneumatic motor 44 driven by pressure pulses in a line 49. A clockwork 50 drives a wheel 55 through a friction clutch 52, pins 71 on the wheel actuating an arm 70 operating a valve (not shown) causing the pulses in the line 49. Liquid from the separator 30 passes through a valve 91 to a float chamber 84. In the chamber full position of the float, air is directed by a line 92 to open valve 93 and close valve 91 to empty the float chamber, and air is also directed by a line 97 to actuate a reciprocating motor 78 having a pawl 79 engaging pins 83 on the wheel. After the chamber has been filled a predetermined number of times, the pawl has rotated the wheel so that the next pin engages the arm 70 unless it has already done so as a result of the rotation of the wheel by the clockwork.

Title: Improvements in and relating to electric circuit-breakers
Inventor: HEWITT JOHN
IPC: H01H3/60
Filed: 1959-10-06
Abstract: 966,079. Shaft couplings. ENGLISH ELECTRIC CO. Ltd. Sept. 30, 1960 [Oct. 6, 1959], No. 33831/59. Heading F2U. [Also in Division H2] An electric circuit-breaker comprises a lostmotion connection between the movable contact and the actuating mechanism, and braking means connected with the contact and operable automatically during opening of the circuitbreaker only when the acceleration of the contact is greater than that of the actuating mechanism. In one form applied to a circuitbreaker having a rotary contact, Fig. 1, the contact shaft 11 carries a driving plate 24 with annular friction surfaces 24a, 24b, which cooperate respectively with the surface of a ratchet-wheel 19 and a lip 18a on a nut which has limited axial movement on the actuating shaft 14 and is in threaded engagement with the plate 24. The ratchet-wheel 19 co-operates with a pair of pawls (Fig. 2, not shown) which permit rotation only during closing. To close, shaft 14 is rotated anti-clockwise (viewed from above) and the inertia of the contact system causes the threads of nut 18 and plate 24 to drive the latter upwards to engage surface 24a with ratchet-wheel 19. There is thus a solid drive from shaft 14 to shaft 11. During a normal opening operation, shaft 14 is rotated clockwise and the contact inertia causes surfaces 18a, 24b to engage and there is again a direct drive. If the shaft 11 is subjected to an acceleration relative to shaft 14, the surface 24a is engaged with the ratchet-wheel 19 which is locked by the pawls so that the friction surfaces brake the movement of the contacts. The brake is immersed in oil.

Title: Percussion fuse for a non-rotating projectile
Inventor: SPINELLI UMBERTO
IPC: F42C1/04
Filed: 1969-07-07
Abstract: 1,271,452. Projectile fuzes. FRATELLI BORLETTI S.p.A. 7 July, 1969 [5 July, 1968], No. 34088/69. Heading F3A. A percussion fuze for non-rotating projectiles, e.g. rockets, effective at direct and oblique angles of impact, comprises a percussion cap 6 mounted in a slide 8 which is movable under delay action from a safe position to an armed position where the percussion cap is aligned with a striker 3; a safety inertia bolt 16 formed with a conical head 15; and a pull-out wire 17 locking the bolt 16 in its safety position. The slide 8, bolt 16 and a powder train 19 are mounted in a body 9 which, in the safe position of the slide 8, is held against axial displacement in the fuze body 7 by a projection 4 of the slide. In use, following removal of the wire 17 and upon launching a projectile fitted with the fuze, the bolt 16 sets back and the slide, which is of the rack-type, is moved to its armed position by a spring 5. On impact with the target, the wall 12 of a cap 1 is deformed and transmits the impact to the striker 3. A recess 11 in the cap enables an axial component to be transmitted to the striker at oblique angles of impact. If the angle of impact is too small for point detonation, the body 9, no longer retained by the projection 4, brings the percussion cap against the striker. In the event of accidental set-back of the bolt 16, e.g. by dropping the projectile, the conical portion of the bolt can re-engage the slide and return it to its safe position.

Title: Improvements in or relating to the purification of benzene hexachloride
IPC: C07C17/38
Filed: 1946-11-18
Abstract: Benzene hexachloride is treated with aqueous methanol or aqueous ethanol so as to remove all the delta isomer present without removing any substantial proportion of the gamma isomer. p  Room temperatures and alcohols containing from 10 to 30 per cent by weight of water are preferred.  The benzene hexachloride used may first be substantially freed from alpha and beta isomers by treatment with ethanol or methanol.  The benzene hexachloride obtained may be further purified by treatment with non-aqueous solvents.  The delta isomer is recovered from the aqueous-alcohol solution by precipitation with water with subsequent recrystallisation from, e.g. carbon tetrachloride.  A table is given of the relative solubilities of the gamma and delta isomers in aqueous-methanol and aqueous-ethanol solutions of varying compositions.  In examples: (1) benzene hexachloride obtained by chlorinating benzene with chlorine, whilst irradiating with a mercury arc lamp is treated with aqueous-methanol the proportion of methanol to water being 80 to 20 and (2) the benzene hexachloride obtained as in (1) is extracted with methanol and the extract, after removal of solvent, treated with aqueous-methanol the proportion of methanol to water being 73 to 27. Specifications 573,689, 573,693, 586,439 and 586,442 are referred to.

Title: Convertible bore concentricity gauge
IPC: G01B5/252
Filed: 1964-08-24
Abstract: 1,021,558. Concentricity gauges, A. EISELE. Aug. 24, 1964, No. 34492/64. Heading G1H. A gauge comprises a dial indicator supported in a housing 14 connected to a handle portion 104, the gauge being gripped in the reference bore K of the workpiece to be gauged, by an expansible bushing 136. Rods 90, 160 extend slidably through the hollow centre of the gauge rod 90 lying in contact with the reciprocable plunger 42 of the dial indicator; and rod 160 abutting a slidable pin 174 formed with a conical end 176 for engagement with the measuring device. To measure the concentricity of the bores of a workpiece with respect to a reference bore R, the gauge is pushed into the bores R and retained there by the expansible sleeve 136. Movement of a measuring pin 180 on the bore I is transmitted through rods 90, 160 to reciprocate the dial gauge plunger 42. The needle of the dial indicator may be zeroized by a nut 37. Rotation of handle 104 moves the feeler 180 around the surface of the bore I, any irregularity being recorded by movement of the dial indicator needle 38. To measure the concentricity of bore E relative to bore R a measuring attachment 20 carrying a ball 212 is slid on to the end of the gauge to bring the ball 212 into contact with the surface E, see Fig. 2. Movement of the ball 212, on rotation of the measuring device around the surface of the bore E, is transmitted through means 202, 196 to the pin 174. Thus, as above movements of the ball 212 are relayed directly to the dial indicator needle. A further attachment 220, see Fig. 4 may replace the attachment 20 to measure the concentricity of bore C relative to bore R, by use of a further slidable pin 232.

Title: Improvements relating to automatic telecommunication switching systems
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q3/00
Filed: 1964-08-25
Abstract: 1,113,234. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 20 Aug., 1965 [25 Aug., 1964; 10 Dec., 1964], Nos. 34709/64 and 50336/64. Heading H4K. In a multi-stage read-relay crosspoint system wherein a relay for each crosspoint has an operating winding and a make contact connected in series with each other between control conductors included in the multiples defining the crosspoint and in which rectifiers are connected to the winding/contact junctions for the purposes of marking a selected path, an additional, similarly poled, rectifier is connected to the control conductors at points where two paths converge. The paths may be an existing calling subscriber/register path and a to be-setup calling subscriber/called subscriber path which utilizes the same crosspoint in the A stage, it being necessary to retain the path to the register until the path to the called party has been successfully set-up. The system is of exactly the same type as disclosed in Specifications 917,017 and 931,028. As shown, a path between subscriber S and register T1 has already been set-up by successively marking leads mc, mb, ma and the path is being held between negative battery at S and earth at T1. A path to subscriber T2 is set-up by earthing mc<SP>1</SP> whereby RCX comes-up to positive battery at T2 and then closing X<SP>1</SP> and opening mc<SP>1</SP>'s contact whereby RBX energizes in series with RCX. At this point, the earth on mb<SP>1</SP> is applied via rbx to point Z common to the new path and the existing path whereby RB and RC are short-circuited and tend to release. By triggering transistor TR in the marker simultaneously with X<SP>1</SP>, point Z is effectively clamped to a negative potential of slightly smaller value than that normally occurring at Z when a path exists therethrough in order to hold-on relays RB and RC. The switches such as X, X<SP>1</SP> may be replaced by a single switch corresponding to the ordinate in the matrix including RB, RBX (Fig. 1A, not shown). In another embodiment (Fig. 2, not shown) the clamping rectifiers f<SP>1</SP> are connected to the marking leads mb, mb<SP>1</SP> &c. at the junction between rectifier f and switch X. In a further alternative (Fig. 3, not shown) the marking and holding potentials are of reverse polarity, thus entailing reversal of the various rectifiers, but in this ease the value of the clamping potential may be considerably reduced, e.g. from - 24 to - 9 volts.

Abstract: 1,041,689. Thermocouples. NORTON CO. Aug. 13, 1965 [Sept. 25, 1964, No. 34711/65. Heading H1K. The arms of a thermocouple are formed integrally by sintering doped silicon carbide particles. The thermocouple may be formed in the shape of a rod with the junction in the middle, Fig. 1 (not shown), by placing particles of P-type silicon carbide doped with aluminium, boron, gallium or indium in one half of a mould, placing particles of N-type silicon carbide doped with nitrogen, phosphorus, arsenic or antimony in the other half of the mould, and then compressing and sintering. Since the material is somewhat porous it may be formed in the shape of a tube through which an inert gas such as argon is passed to purge the device. As shown, Fig. 2, the two arms of the thermocouple may be arranged concentrically, the inner arm 17 being supported at intervals by insulators (not shown). The junction 21 is entirely enclosed but if necessary the device may be hermetically sealed by surrounding it with an impervious enclosure or coating. Alternatively inert gas at a higher pressure than the external ambient may be forced into the closed tube so that it diffuses out through the porous structure to protect the device. The connections to the cold ends of the thermocouple can be made by soldering, welding or mechanical clamping. The impurities may be introduced into the silicon carbide particles during or after growth or may be diffused into the structure after it has been sintered or at another stage of manufacture. Different concentrations of the same impurity may be used to form the arms of the device. More than one interfacial region may be provided.
