Abstract: 972,721. Lamp holders. L. D. MOSS. March 6, 1963 [March 16, 1962], No. 10213/62. Heading H2E. In a lamp holder for a fluorescent lamp comprising an insulating casing 19 and an insert 20 having contact apertures 37 for receiving the lamp pins, the insert 20 is formed with a recessed end surface 41 into which the lamp cap is guided by casing edges 39 extending outwardly and downwardly from an arcuate lamp-rest edge 40 at the rear of the casing 19 to join casing side walls 22. The surface 41 is itself recessed at 43 to accommodate the lamp pins as the lamp cap is moved along edges 39 towards the boundary 36 of surface 41. The lamp holder is mounted for rocking movement at each end of a fluorescent light fitting comprising a channel having a flat base 2 and bulbous side walls 3, 4 by means of an attached spring 16 which hooks into the holder and urges it against a casing stop 17, the holder being held perpendicular to the channel base 2 when the lamp is removed by channel abutments 18. The spring hook 28 engages in a slotted plate 29 integral with casing 19 (shown without insert in Fig. 4) and also in a forwardly bent slotted part 34 of an earthing strip 32 held in position by an insert-securing screw 21 and having at the other end a tongue portion 32a which projects through insert 20 to engage the lamp cap. Leaf spring contacts 44, which are mounted between the back wall 25 of the casing and the insert 20, comprise tapered pin-engaging ends located behind elongated contact apertures 37, and lead terminals 45. Instead of mounting the holder directly on to the fitting channel, as above, it may be mounted by a steel sub-frame (Figs. 9-11, not shown) screwed into each end of the fitting channel. As before, a spring, fastened in this case to the sub-frame, is hooked into the holder, but in this case the holder is held upright by tongues projecting from the end of the subframe into recesses 61 and 66 in the lower end of holder casing 19. The section of the channel between the two end holders contains a choke, a condenser, and a starter switch, and is closed by a cover.

Title: Improvements in or relating to the purification of alcohols by extractive distillation
IPC: C07C29/74
Filed: 1950-04-27
Abstract: Crude aliphatic alcohols obtained from olefins, particularly C2 to C6 alcohols obtained by the hydration of olefins using sulphuric acid, are purified from both highand low-boiling impurities by extractive distillation using an aqueous solution of a glycol, a glycol ether or a glycol ether-ester containing 20 to 80 volume per cent of the glycol component, as solvent.  The crude alcohol is introduced at an intermediate position of the fractionating column; and <PICT:0672433/III/1> the solvent is introduced at or near the top of the column in sufficient quantity to maintain 70 to 99.9 volume per cent of solvent in the internal reflux.  The impurities are withdrawn from the top of the column-normally 8 to 15 per cent of the organic material in the crude alcohol feed is ejected in the heads.  A 5 to 30 volume per cent solution of the purified alcohol in the aqueous solvent is withdrawn from the base of the column, and the purified alcohol is recovered from this extract by ordinary fractionation.  In the case of the higher alcohols such as the pentanols, the watersolubility may be enhanced by addition of isopropanol or tertiary butanol.  A list of suitable solvents is given in the Specification.  Crude secondary butanol containing about 70 volume per cent of secondary butanol, the remainder being water, and impurities such as butyl ether, was fed through line 1 on to the 40th plate of 50plate fractionating column, and an aqueous solution containing 40 volume per cent of ethylene glycol was introduced into the top of the column through line 3.  The heads taken off through line 5, comprised 13.7 per cent of the organic material in the feed. After condensation, the heads were rejected from the system through 7-none was returned to the column as reflux.  The extract withdrawn frim the column through line 4 contained 21.75 volume per cent of secondary butanol; this extract was fractionated in 30-plate column 13, and the pure secondary butanol/water azeotrope was withdrawn through line 15.  Aqueous ethylene glycol was recovered from the base of column 13 and recycled through line 18, together with make-up water added through line 17, to the top of column 2.

Title: A method of and an apparatus for gas analysis
IPC: G01N27/74
Filed: 1956-04-05
Abstract: <PICT:0824854/III/1> The constituents of a gas mixture, e.g. flue gas and inflammable gas mixtures, are measured by combustion with the oxygen contained in the mixture, or added thereto, measuring the change in oxygen content in a paramagnetic oxygen meter where the flowing gases are exposed in a thermal conductivity cell to a constant inhomogeneous magnetic field both before and after combustion, and in then determining the difference in oxygen content. From this result the calorific value of the combustible constituents, or the proportion of other reactable components can be determined. The consumption of oxygen in combustion with a range of combustible gases is given in the Specification.  The gas mixture enters a pipe 1, Fig. 1, and a part flows through combustion chamber 4, and the other part through a compensating chamber 5, together with a known amount of oxygen or air from a pipe 20 if required.  The outlets from chambers 4 and 5 lead through two-way valves 6, 7 to a paramagnetic oxygen meter 10. The gas not under measurement passes through a by-pass 14, 15. The oxygen concentration is indicated on a meter 13, and co-ordinated measurements shown on a recorder 12.  In modifications, two or four paramagnetic oxygen meters are used, and connected in a Wheatstone bridge circuit, the unreacted gas to be tested passing through one meter or a pair of meters, and the reacted gas passing through the second, whereby a direct reading of the combustible constituent is obtained.  In addition the circuit may be unbalanced so that the zero reading accounts for the air of oxygen added.

[Class 80 (ii)] In a change-speed gearing, in particular of the syncromesh type, the engaging movement of the operating member is provided with power assistance during an intermediate part of its movement, the commencement and completion of the movement, and the whole of the disengaging operation being effected manually. Selector rods a, f, adapted for manual operation by a gear changing lever (not shown) are provided at their their ends with pistons d, e, i, j, which are subject to oil pressure from conduits k and through a valve m connected to the vehicle clutch pedal so that the pressure fluid is only supplied to operate the gears when the clutch is disengaged. A further valve p controls a connecting conduit n between the ends of the selector rods and is connected to the gear lever so that it is open when any gear is engaging or engaged but closed in the neutral position shown. To engage a gear the clutch is first operated tc open the valve m which admits pressure oil tc both ends of the selector rods which are thus balanced, a n d either selector rod accord. ing to the gear being engaged is then moved manually against the balanced fluid pres sure until the inner edge of one of the pistons uncovers a groove d', e', i', or j<3> to release the pressure on that piston to the interior of the gear box. The pressure on the opposite end of the selector rod then effects continued movement-' of the selector rod until the valve p is opened towards the end of the movement. The two ends of the selector rod are then put into equilibrium and the final movement is effected by manual operation alone. During the manual disengagement of a gear the valve p remains open until the selector rod is moved to.uncover the one of the supply ports d<2>, e', i'. or j<2>, which is covered when it is closed by the gear changing lever without upsetting the equilibrium between the two opposite pistons or affecting movement of the selector rod.

Void [Abridged as open to inspection under Sect. 91 of the Acts, April 19, 1932]. [Classes 72, 82 (ii), and 117.] Apparatus for separating granular materials of different shapes and kinds comprises inclined surfaces on which the materials move and means such as gaseous or liquid currents, and mechanical or magnetic devices are caused to vary the natural paths of the particles under the action of gravity in different degrees. As shown in Fig. 1, the material is delivered to a series of inclined planes 1-4 arranged in zig-zag formation and at the lower edge of one or more of the planes a gaseous or liquid current from a source 10 is caused to divert the material from its natural path. Alternatively, an electromagnet 7 acts under the planes to retard the movement down the plane of certain of the constituents. The separated products are collected in the receptacles 8, 9. Fig. 2, shows an apparatus in which a single plane 1 co-acts with an inclined endless band 11 which at its upper end throws the material carried forward into different compartments of a receptacle 13. Another part of the material runs down the band and is delivered to compartments of a receptacle 14. A liquid or gaseous current, or a magnetic field may act on the materials at the lower edge of the plane 1 to produce a preliminary separation. In Fig. 4 (not shown), the endless band may be replaced by a rotating cylinder. According to further forms of construction, the inclined surfaces may be inverted cones, and the apparatus may be arranged to work in successive stages. Fig. 7 shows an endless band 31 running round horizontally and vertically disposed rollers 32, 33 so that the upper run of the band is skew. The materials move differentially on the band and are collected at different places in receptacles 35. The band may be made of textile material, rubber, sheetmetal &c. and may be wetted with an oil to increase the adhesion of some of the materials. Alternatively a stationary surface, which is vibrated, may be used. This apparatus may be combined with gaseous or liquid currents, magnetic fields, &c.
