Abstract: 676.774. Guiding motor vehicles. BROCKHOUSE & CO., Ltd., J. Feb. 13, 1950 [Feb. 15, 1949], No. 4085/49. Classes 79(i) and 79(v) In a wheeled vehicle for use on a trackway of the kind comprising a track of width corresponding substantially to the gauge of the vehicle wheels and a central guide rail projecting above the track, which rail is engaged by guide means on the vehicle, the guide means comprise a pair of laterally spaced rollers rotatably mounted on vertical stub axles which have threaded engagement with the vehicle frame so that the height of the guide rollers can be adjusted to compensate for wheel and track wear. As shown, the invention is applied to a locomotive 11 having tyred wheels 12 adapted to run on the concrete or other rigid track 10 and the guide rollers 16. The rollers 16 are arranged in two pairs at each end of the locomotive and are adapted to engage the central rail 13 which is supported as at 14 to prevent snow &c. drifts. Each roller 16 comprises a hollow cylindrical body 17 rotatably mounted by bearings 18, 19 on a pin 20, the bearings being held between a shoulder 23 and a nut 22. The pin 20 is eccentrically mounted on the threaded stub axle 21, the threaded portion engaging a bush 27. At the top of the axle 21 is a kerf 39 by means of which the axle can be rotated to raise the roller 16 to compensate for wear on the track 10 and wheel tyres and by virtue of the eccentric pin 20 the roller can be adjusted laterally on rotation of the axle to compensate for wear on the rail 13 and roller. A plate 28 carries two bushes 27. A pair of plates 28 are interconnected by bracing members 37 and each plate 28 is secured in its middle portion to the lower part 29 of a cranked axle 30 carrying the wheels 12. Vertical portions 31 of the axle 30 are guided between plates 32 carried by the vehicle frame 33. The axle 30 is connected with the frame by leaf springs 34, the ends of which are connected to lugs 35 on the vehicle frame. Specifications 642,699 and 676,775 are referred to.

Title: Improvements in or relating to determining and/or controlling the proportions or ratio of two substances in a composition of those substances
IPC: G01N23/08
Filed: 1946-02-11
Abstract: <PICT:0641074/III/1> In apparatus for determining the proportions of two substances in a composition or compound without direct testing, a beam of penetrative radiation comprising gamma rays is transmitted through the composition and the intensity of the radiation beam is measured on emergence, the apparatus being calibrated by transmission of the beam over the same path length through each substance separately, or through a known mixture.  In Fig. 1 a vessel 10 contains a liquid or solid composition 12 which may be a mixture, emulsion, solution or chemical compound of two substances.  A gamma-ray absorbent block 14 contains a radioactive substance 16 and a beam of gamma radiation 22 passes through the vessel and composition into a radiation detector 26 (which may be a Geiger-Muller counter, a proportional counter or an ionization chamber) connected to an amplifier 28 and a measuring instrument 30. The absorption of gamma rays being dependent on the number of atoms per unit volume of absorbent, the proportions of the two substances in the composition may be calculated from the absorption of gamma radiation therein, and the absorptions of the two constituents tested separately, a correction being made for the absorption of the vessel walls.  In a modification (Fig. 2, not shown), the invention is shown applied to the continuous determination of acid catalyst in the alkylation of hydrocarbons for the synthesis of aviation spirit.  In a further modification (Fig. 5, not shown), the measuring device is used to control the concentration of catalyst flowing into a reaction vessel. Applications to various other chemical processes, and to the measurement of density and temperature are indicated, while the penetrative radiation may consist of neutrons, alpha rays, electrons or protons.

[Class 4.] Internal-combustion engines have cylinders arranged in pairs inclined to offer less head resistance to flight. The individual crank shafts 31 are separately geared to the propeller shaft 21. The Specification as open to inspection under Sect. 91 (3) (a) also describes the following arrangements :-Two independent engine units drive a common propeller shaft 11, Fig. 1 (Cancelled), through clutches which disengage the positive drive of one unit if it should stop. On the crank shaft 1 of each engine is keyed a hub 2 formed at one end with the coned part 9 of a friction clutch ; on the grooved exterior of the hub slides one part 3 of a ratchet clutch, the hollowed counter part 10 of which also serves to receive the friction cone 9. Both clutches are held off by a lever 5 through springs 7, 12. The engines are started up from the propeller through the friction clutches, the ratchet clutches being afterwards let in ; if an engine slows down the ratchet clutch allows the driven part 10 of the clutch to overrun, the friction clutch slipping. An electric alarm indicates which engine is slowing, and by the lever 5 both clutches may be held open. In each engine the cylinders may be coaxial or sets of V-engines may be used ; two banks of cylinders 44, 45, Fig. 9 (Cancelled), may form the two engines. The cylinders may be arranged with the axes parallel to the length of the fuselage. In another arrangement with oppositely moving pistons in each cylinder 42, Fig. 8 (Cancelled), the latter are vertical on each side of the casing 43 enclosing propeller gear. This subject-matter does not appear in the Specification as accepted.

Abstract: 1395911 Measuring torque HAWKER SIDDELEY DYNAMICS ENG Ltd 15 May 1972 [13 Feb 1971] 4570/71 Headings G1N and G1W In an apparatus for measuring torque in a shaft by measuring the twist in the shaft between two locations by means of a peripheral index marks rotating with the locations and probes sensing the passage of the index marks, the index marks and probes are arranged, so as to prevent or compensate for errors caused by non parallelity of the shaft axis and the axis on which the probes lie. In Fig.3, the rotation of location A is transferred to location B, and the twist is measured by means of index wheels W 1 , W 2  and probes, not shown. In a more accurate modification of  Fig.3, (Fig.4), wheel W 1  carries a further index wheel W 3  and probes D 1 , D 2 , D 3  monitor the passage of wheels W 1 , W 2 , W 3 . By subtracting the difference in the readings of probes D 1 , D 3 , from the difference in the readings of probes D 1 , D2 the error caused by non parallelity of the shaft axis and the probe axis is compensated for. In Fig.7, two probes D 1 , D 1 'co-operate with wheel W 1  and two probes D 2 , D 2 'co-operate with wheel W 2 . By subtracting the difference in the readings of detectors Di, D2 from the difference in the readings of detectors  D 1 ', D 2 ', a value of the twist of the shaft is obtained which is compensated for erros due to non-parallelity of the shaft and probe axes and for errors due to lateral misalignment of one end of the shaft. In Fig. 8, a saddle M is rotatably mounted on the shaft and carries the electromagnetic inductive probes 23, 24, 25 and 26 which co-operate with slotted wheels 11. The saddle arrangement maintains the probe axis parallel to the shaft axis, and the four probes may be used as in Fig.7 to overcome any residual inaccuracies.

A lace-net machine warp guide 6 (e.g. the background bar of a bobbinet machine) is built up from a plurality of sections, each having at least two parallel rows of equally spaced apertures 19, the apertures of one row being staggered relatively to those of the next adjacent row. Mating ends of the sections are inclined at 25, 26 to be substantially parallel to the line of controls of two next adjacent apertures in the two rows, as shown. In extent along the rows, any aperture overlaps the two immediately adjacent apertures in the other row, so that any warp threads which pass through apertures 20 in jacquard bars 5 may have sufficient freedom of relative movement, when the jacquard bars are shogged relatively to one another, to enable, say, warp threads A, B to be sufficiently closely approximated under control of jacquard bars 5, to be wrapped as one by a bobbin thread: the bobbinet pattern may thus be superimposed on the plain background net formed by the interaction of the bobbin threads, the back warp threads passing through wire eyes 22 on slidable bars 24 and the front warp threads passing through the apertures 19 in the warp guide, all sections of which are shogged in unison by a bar 18. The sections 6 may be of flat sheet material (e.g. brass) cast into a block of lead or lead alloy. After leaving the beam 2, the warp threads pass through a separator 4.
