Patent GB-502971-A (GB)
Title: Improvements in means for detecting the presence of suspended matter in fluids
IPC: G01N21/53
Filed: 1937-09-28
Abstract: 502,971. Photo-electric apparatus for detecting suspended matter in fluids. BRITISH ELECTRICON (LONDON), Ltd., ROBINSON, W. A., and CHAMBERS, W. A. Sept. 28, 1937, No. 26257. [Class 40 (iii)] Relates to photo-electric apparatus of the kind in which a photo-electric cell normally in the dark becomes illuminated when a fluid passing through a lighted chamber contains particles of suspended matter, the illumination of the cell being due to reflection or refraction by the suspended particles, for example as described in Specification 272,914, [Class 40 (v)]. According to the invention, the fluid conveying installation together with the light source and the light-sensitive device form a stationary system, and an optical travelling unit is provided to scan a number of fluid streams in succession, a distributing switch device being moved at the same time to connect the corresponding signal circuit to the amplifier controlled by the photo-cell. As shown in Figs. 2 and 4, a number of chambers 3 are disposed around a rotary scanning device 15 and are supplied with fluids by a number of pipes 2. The fluids are discharged through outlets 9 to an upper space 7 and then through outlets 10 to a hood 11 connected to an exhauster (not shown); or the fluids may be led from the chambers 3 directly to the hood 11. The chambers are illuminated by electric lamps 13 directly below bottom openings in the chambers 3. The rotary scanning device 15 contains a reflector 18 and is carried by an insulating disc 19 provided underneath with a contact piece 25 adapted to bridge pairs of contacts 28, 29 in succession as a window 16 in the scanning device comes opposite a window 8 in a chamber 3. In this position of the scanning device, if the fluid in the chamber 3 is clear, no light is received by the scanning device ; but if the fluid contains suspended matter, light therefrom passes into the scanning device and is reflected through a window 17 on to a photo-cell 31 in an opaque casing 30. This cell is connected to an amplifier 45, Fig. 5, which operates a relay 44 to close a contact 43 when light strikes the cell. This completes the circuit of the drop indicator 39 corresponding to the contacts 28, 29 bridged over by the contact piece 25, thereby indicating the particular chamber 3 in which there is matter in suspension. At the same time, a relay 42 closes the circuit of a main power alarm. As shown in Fig. 5, the circuits of the signals 39 are fed from one source A, and the amplifier 45, the lamps 13, and the motors 23, 24 for driving the scanning device are fed from mains 34. Two driving motors 23, 24 are provided, so that one can act as a stand-by. In a modification, Fig. 6, two cells 31, 51 are used in conjunction with two reflectors 18, 18<1> and two windows in the scanning device. These cells may be used at the same time' to check each other; or one may be switched out to act as a stand-by.

As described the sections 2, 2' include tubular frames 3 supporting panels 15, 15' of fabric or plastics. When fabric is used each panel is of double thickness and the outer layers are extended to form flaps 37, 39 which are joined at 41 to provide the side flaps 27, 27'. A drawstring 45 is threaded through eyelets in the side panels and panels 15, 15' for closing the case when in the Fig. 3 position or for supporting the panels 15, 15' at the desired angle in the Fig. 4 position.

[Also in Divisions F1 and F2] Means for converting to four-wheel drive a tractor having rear wheels 9, 10 driven by a hydrostatic motor 5 fed through conduits 6, 7 from an engine-driven pump 3 comprises a pair of hydraulic motors 16 which are attached to the front axle to drive the respective wheels thereon, and flexible pipes 28, 29 which are connected to the conduits 6, 7 to supply fluid in parallel to the motors 16. The rear wheels 9, 10 are driven from the motor 5 through differential gearing 8. The pump 3 and motor 5 are of adjustable swash-plate type. Each motor 16 includes a stub shaft 18 (Fig. 3, not shown), which is journalled in a housing (17) attached to the front axle in place of the original wheel carrier and carries a rotor (21) formed with axial cylinders containing pistons (22) bearing on a cam surface (23) in the housing (17). Grooves (24, 25) in the housing communicate in turn with the cylinders and are connected to the pipes (28, 29) by passages (26, 27).
Patent GB-1042119-A (GB)
Title: A process for the production of hydrocarbon lead compounds
IPC: C25B3/13
Filed: 1965-06-22
Abstract: Organo-lead compounds containing 1 to 3 vinyl groups and at least one alkyl group are made by electrolysing a mixture of a Grignard reagent and a hydrocarbon halide, the hydrocarbon radicals being different, but one being a vinyl group which preferably is present in the Grignard reagent.  Vinyl groups are defined as R2C=CH-in which R2 is H, methyl or ethyl. The hydrocarbon halide may be an alkyl bromide or chloride containing 1 to 8 C atoms.  A lead anode is used which may be alloyed e.g. with Sn, Bi, As, Cd, Cu, Li, Mg, or Zn.  Cathodes may be lead or stainless steel. Electrolysis is effected preferably at up to 20V, and at 15 DEG  to 100 DEG C, and under pressure.  The main products range from trialkyl vinyl lead to alkyl tri vinyl lead, but tetra-alkyl, and tetra-vinyl compounds are also present, and the nature of the product is controlled by the relative proportions of reactants, and process conditions.  Solvents may be added e.g. ethers, polyethers, aromatic hydrocarbons, amines, amides, or other organo-metallic compounds.  For example, vinyl magnesium chloride is dissolved in benzene and dibutyl carbitol and methyl or ethyl chloride added during electrolysis at 5V, using a lead anode sandwiched between stainless steel cathodes. The cell was cooled. Initial current of 200 mA fell to 80 mA over a 2 1/2 hours run.  The products were alkyl vinyl lead compounds with some tetramethyl and tetravinyl lead.  No triorgano-lead compounds were present.  In other examples, the reactants are ethyl magnesium bromide and vinyl bromide, and propenyl chloride and methyl magnesium chloride.

Title: Improvements in or connected with wheel landing gear for aircraft
IPC: B64C25/12
Filed: 1933-09-28
Abstract: 426,134. Aircraft landing gear. VICKERS (AVIATION), Ltd., and WALLIS, B. N., Byfleet Road, Weybridge, Surrey. Sept. 28, 1933, Nos. 26713/33 and 27715/34. [Class 4] In landing-gear for aircraft in which a wheel carrier member projects downwardly and forwardly when extended for landing or taking-off, the carrier member is mounted to swing about lateral and fore and aft axes, means are provided for displacing it about one of the axes and a controlling member for causing movements of the carrier member about one axis to displace it about the other axis also. In one form, a sheave 2 is rotatably mounted on a tube 1 and is pivotally connected with a landing wheel fork 7 by lugs 3. The forward portion of the upper end of the fork is formed as a yoke 9 having pins 10 which engage in cam slots 11 in plates 12 secured to the tube 1 so that on rotation of the sheave the wheel moves laterally and rearwardly into a recess in the wing which may also house a fuel tank. The fork is retracted through a frame 13 connected to the sheave and to a rod 14 connected to mechanism operable by the pilot from the cockpit to turn the sheave through approximately 90‹. A locking device comprises two pairs of bolts 15, 16 ; 17, 18 each connected by a link 19 to one or other of two collars 20 mounted on a shaft 21 provided with an arm operable by mechanism to effect projection or retraction of the bolts. The bolts 15, 16 engage holes 23 in the sheave to prevent its rotation whilst the bolts 17 engage holes in the yoke to prevent its turning about its pivots. An abutment 25 on the yoke engages a stop 39 on the tube to assist in holding the fork. The tube 1 is mounted to slide on two tubes 26, 27 fixed to the upper and lower booms 31, 32, 33, 34 of the wing, under the control of an oleo strut 28. In a modification, the wheel 40 is carried on an arm 41 connected by pivots to a slide 46 movable under the action of oleo struts 49, 50 and supported by guides 47. A radius rod 54 is universally jointed to both the arm 41 and the slide 46 and effects the necessary movement of the wheel during retraction. Retraction is effected by a folding stay formed in two parts 57, 59 pivoted together by a folding joint 61 and at their other ends pivoted respectively to a beam 58 and the arm 41. The stay is folded by a worm wheel segment 62 meshing with a worm 63 on a shaft 64 mounted in the part 57 and rotatable through gearing and shafting from the cockpit.
