Patent GB-984421-A (GB)
Title: Electrolytic production of lead alkyl compounds
IPC: C25B3/13
Filed: 1961-03-15
Abstract: <FORM:0984421/C6-C7/1> Lead alkyl compounds are made using a lead anode and an electrolyte containing a Grignard reagent, e.g. EtMgCl, alkyl chloride, and an ether of higher boiling point than the lead alkyl, e.g. the dibutyl or hexyl ethyl ether of diethylene glycol. The electrolytic product is treated with HCl forming two layers, the copper containing the lead alkyl, high boiling ether, and any other solvent, and the lower one containing MgCl2 solution and some solvent. These are then separated, and distilled to recover the product and individual solvents. Alternatively the product may be freed from light solvent components when separate layers are formed, and the lead alkyl layer after some extraction and concentration of the lead compound, recycled to the electrolysis stage. Tetrahydrofuran or benzene may be used as extracting solvents, which are of lower boiling point than lead tetraalkyl.  As a further modification these extraction solvents may be added to the electrolyte, and lower boiling members removed from the electrolyte product by "flashing off" at low pressure. Grignard reagent is formed in a vessel 11 by adding Mg metal, methyl or ethyl chloride, benzene or tetrahydrofuran, and the diethylene glycol ether.  The mixture passes to the electrolyte cell 19, and additional methyl chloride is charged during electrolysis.  The cell contains lead anodes and stainless steel cathodes, and the electrolyte is cycled externally through a cooler 31.  Reaction is effected at 41  DEG C. and 3.1 p.s.i.g. After 11 hours 95% of the Grignard metal is connected to the lead alkyl. The product passes to a cooler 33 and then to a separating vessel 36 to which dilute HCl is added, mixture being effected in a turbine mixer, e.g. in the line 34.  The lower aqueous layer containing some solvent is drawn off and solvent recovered in an azeotroping tower 41.  The upper phase is distilled in a vacuum tower 43, the overhead stream containing tetrahydorfuran, some benzene, and traces of other products, and is returned as a reflux to the vacuum tower 43.  This is connected to a drying tower 55 and other units to recover and separate the components as necessary. The bottoms containing some benzene, all the glycol ether and lead alkyl, passes to a steam distillation tower 83, from which the lead alkyl and benzene comes off the top, and the glycol ether forms the main constituent of the bottom.  These two fractions are further treated in distillation and drying towers to separate the constituents.  The progress of the electrolyte stage may be estimated by conductivity, tests details of which are given.

Patent GB-1355479-A (GB)
Title: Radioactivity well logging
IPC: G01V5/10
Filed: 1972-03-01
Abstract: 1355479 Bore-hole logging TEXACO DEVELOPMENT CORP 1 March 1972 [5 March 1971] 9509/72 Heading G1A In a bore-hole logging apparatus comprising a neutron source 26, a gamma-ray detector 30, 31 and a pulse height analyzer 21 having two channels 19, 20 corresponding to two different energy ranges of the gamma-radiation incident on the detector, a shield 50 of pre-selected material substantially surrounds the detector portion 30, the material being chosen to emit a relatively greater amount of gamma-rays, on bombardment by a given amount of thermal neutrons, in the lower energy range than in the higher. As explained below, this means that the lower energy channel output is indicative of the H2 content of the earth formation, whereas the higher energy channel output is indicative of H2 + Cl2. If the shield 50 were absent, and the probe 25 passing through a region containing H2 - e.g. oilbearing strata - then thermal neutrons from the source 26 would be absorbed by the H2 and reemitted as gamma-rays. The amount of gamma-radiation received by the scintillation detector 30, 31 would indicate the concentration of H2. However Cl2 has a greater cross-section than H2 for the absorption of thermal neutrons and subsequent re-emission of gamma-rays, so the presence of Cl2 in a stratum would upset a measurement for H2. With the shield 50, e.g. of samarium, gadolinium or europium, present, when passing through a stratum bearing a given proportion of H2 only, the gamma-radiation produced by bombardment of the H2-containing rock is augmented by the gamma-radiation produced by bombardment of the shield by thermal neutrons. If the probe then encounters rock containing the same proportion of H2, but also a certain amount of Cl2, the Cl2 will absorb a relatively large amount of thermal neutrons, emit a correspondingly greater amount of gamma-rays, and hence tend to increase the detector output. However absorption by Cl2 will leave less thermal neutrons available for capture by the shield 50, and hence tend to decrease the detector output. The shield thickness and lower energy range are selected so that the above two effects cancel out one another, and then the detector output in the lower energy range is proportional only to H2 concentration. However, the shield material is also chosen such that in the higher energy range, e.g. 73À43 MeV, its neutron capture cross-section is substantially less than in the lower range, e.g. 1-3MeV. Hence the detector output in the upper range is proportional to H2 + Cl2. The outputs in the two ranges may be displayed directly on two recorders, or may be ratioed or subtracted before display. The probe is preferably calibrated in a stratum of known H2 and Cl2 content. As shown, the detector may be contained in a vacuum cooled arrangement 35-40.

Title: Improvements in or relating to electric discharge lamps for producing intense flashes of light
IPC: H01J61/33
Filed: 1949-04-07
Abstract: 671,384. Discharge lamps. GENERAL ELECTRIC CO., Ltd., and WILLOUGHBY, A. H. May 26, 1950 [April 7, 1949], No. 9528/49. Class 39 (i). The quartz envelope of a discharge lamp for producing intense flashes of light of very short duration is of dumb-bell shape, the axial length of the bar portion 1 being greater than its internal diameter, and the internal volume of each bulbous end 2 being considerably greater than the internal volume of the bar portion. Tungsten or molybdenum electrodes 4 are sealed through the bulbous ends by known quartz seal techniques, the discharge surface of each electrode being adjacent the corresponding opening of the bar portion, so that the greater part of the discharge lies within the bar. The short discharge path renders the lamp suitable for use in optical projection apparatus. A length of wire 6, attached to the envelope and closely following its contour, may be used as an auxiliary triggering electrode. The filling is krypton or a krypton-xenon mixture; exemplary dimensions and gas pressures are specified.

Title: Fuze for gyrating and non-gyrating projectiles
IPC: F42C9/04
Filed: 1958-03-25
Abstract: 848,767. Ammunition fuzes. U.F.A. UNIVERSAL-FINANZIERUNGS-ANSTALT. March 25, 1958 [March 28, 1957], No. 9606/58. Class 9(1). A direct-action percussion fuze having a safety device locking the striker on the initial portion of the trajectory and comprising a clockwork mechanism started by the setback of an inertia mass is provided with a spring-driven shutter obturating the flash from a primer to a detonator, the shutter being locked by the clockwork mechanism until the striker is released. The clockwork comprises a rack 2 stressed by a spring 4 and connected by pinions to a toothed wheel e 4'  engaged by a balance-wheel b, Fig. 2. After firing a projectile fitted with the fuze, a mass 8 sets back due to inertia and withdraws a split pin 6 so unlocking the balance-wheel and rack 2. The rack 2 moves transversely, its traverse controlled by the clockwork, until the firing pin, which extends through a keyhole slot 11 arrives at the large end 15 of the slot and can be driven against a primer 21 by a blow on the nose of the fuze. The reduced end of the primer carrier 18 moves into the slot 11 due to the pressure of a conical stop 39 carried by the shutter 37, which has a non-circular aperture 38 engaging an axle 28 extending from a plate 26 housing a detonator 27, the axle being surrounded by a driving spring 33 which drives shutter and plate as a unit. A housing 22 for the plate 26 also contains a delay charge 23 covered by the shutter 37. The forward movement of the carrier 18 frees the stop 39 and the spring 33 drives the shutter 37 until a notch 45 engages an adjustable stop 42, a mounting plate 31 being provided with an arcuate groove 40 along which the stop 39 travels as the shutter rotates. According to the setting of stop 42, the shutter 37 and plate 26 come to rest either with the detonator 27 aligned with the delay 23 or a port 24 is put into communication with the detonator and the flash passage from the primer 21. The base of the fuze is closed by a plug 52 with a thin-walled recess 53 ruptured by the detonator 27 to fire a charge 60. The mass 8 may be locked during transport by a pin extending through the fuze casing 1 to engage a groove in the mass. If the charge 60 is such as can be initiated by the primer, the detonator 27 together with plate 26 may be omitted.

Title: Improvements in and relating to starting devices for fluorescent tubes
IPC: H05B41/10
Filed: 1957-03-25
Abstract: 806,185. Supply systems for discharge lamps. LEUENBERGER, H. March 25, 1957 [March 27, 1956], No. 9713/57. Class 38 (4). A two-terminal starting switch for fluorescent tubes comprises three circuits. The first circuit comprises a coil 12 of relay 12-17, a contact 18 and resistor 19 connected in series with heaters 4, 5 of lamp 1. Closing switch 8 energizes coil 12, closing contacts 17 connecting the second circuit, comprising opposing coil 13, negative coefficient resistor 21 and bi-metal 22, also the third circuit comprising positive coefficient resistor 23. The shunting effect of the second and third circuits reduces the current through coil 12, but armature 15 is held by remanent magnetism. As resistor 21 heats, the demagnetizing effect of coil 13 increases and contact 17 opens. In the event of several false starts, contacts 18 open to enable contacts 17 to cool between switching operations. The total current through the second and third circuits remains approximately constant due to the opposite characteristics of resistors 22, 23.
