Title: Improvements in incendiary projectiles
IPC: F42B12/44
Filed: 1942-03-30
Abstract: 570,836. Metal soaps; liquid fuels. BILLING, J., and FISHER, J. W. March 30, 1942, No. 4250. [Classes 1 (iii) and 91] [Also in Group XXI] An incendiary bomb is charged with a viscous solution in a highly inflammable liquid hydrocarbon of a metal soap of an aliphatic acid containing 10 or more carbon atoms in the molecule. Preferably an aluminium or iron soap in which approximately two aliphatic acid radicals are present for each metal atom is used in concentration of about 5 per cent, in a hydrocarbon containing a substantial proportion of benzene. The soap is prepared by reacting a solution of an alkali metal salt of the aliphatic acid containing a small excess of free base with a solution of a salt of the metal. A small quantity (0.05 to 0.2 per cent.) of a watersoluble phosphoric acid salt such as trisodium phosphate may be added and a small quantity not exceeding 0.5 per cent. of water. The presence of more than one metal in the soap is liable to lead to solutions of low viscosity. In an example 100 parts of stearic acid are neutralised with caustic soda,, 4 parts of additional caustic soda added, and the solution brought to a concentration of about 2 per cent. 61.5 parts of aluminium sulphate (Al2 (SO4)3 18. H2O) dissolved in 3,000 parts of warm water are added, and the precipitated aluminium distearate containing 8.6 to 8.75 per cent. Al2 O3 is washed and dried. This powder is dissolved in warm benzene to 25 per cent. concentration and is subsequently diluted to 5 per cent. concentration for use. 0.2 per cent. of water and 0.1 per cent. of trisodium phosphate may advantageously be added.

Title: Improved process of producing pigmental colouring matter
IPC: C09C1/02
Filed: 1936-02-13
Abstract: Coloured pigments, containing barium sulphate as the basic material, are prepared by precipitating barium ions by sulphate ions in the presence of colouring compounds of manganese or other heavy metal, at normal or slightly increased temperature, mixing the precipitate with a nitrate, and melting, sintering and calcining the mixture.  A permanganate, manganate or manganite may be employed as the colouring compound, and it may be partly or entirely replaced by corresponding compounds of chromium, vanadium tungsten or molybdenum, by mixtures of such compounds, or by complex salts, such as the heteropolyphosphates or the heteropolysilicates, of these metals. Further variety of shades and colours can be obtained by the addition of such substances as the sulphates and nitrates of cerium, zinc, chromium and iron. According to examples: (1) mixed solutions of a manganate and of sodium sulphate are precipitated by barium ions, and the mixed precipitate of barium sulphate and barium manganate is washed and dried.  It is then mixed with barium nitrate and heated, in stages, to 750 DEG  C.  The resultant mass is powdered and treated with dilute acid, yielding a rich blue pigment; (2) mixed sulphate and chromate ions are precipitated by barium ions, and the precipitate is mixed with barium nitrate and compressed into tablets which are heated, in stages, to 750 DEG  C.  The product is powdered, twice boiled with dilute hydrochloric acid, then treated with dilute sulphuric acid, washed and dried, yielding a stable green pigment. According to the Specification as open to inspection under Sect. 91 the manganese compound may be replaced by an iron compound, and the nitrate may be replaced by a nitrite.  Further, the barium sulphate need not be precipitated in the presence of the colouring compound, but may be merely mixed therewith, prior to mixing with the nitrate. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 444,110.

Title: Improvements relating to intermittent drive mechanisms
IPC: F16H27/06
Filed: 1948-02-16
Abstract: 633,285. Intermittent toothed gearing. SMITH, F. C. Feb. 16, 1948, No. 4446. [Class 80 (i)] The driving pin 10 of an intermittent drive of the Geneva type is adapted to be moved on the driving wheel 1 to either an operative or inoperative position with respect to the driven member 2 and is acted upon by a spring 12 to move outwardly in a supporting slot 11 but is adapted to be moved inwardly on engagement with a cam surface 29 on a member 3 pivoted on a fixed pivot 23. With the parts in the positions shown the pin 10 is inoperative and no drive is imparted to the driven member 2. If the member 3 is rocked in a clockwise direction by a solenoid or other suitable actuating means an end 31 thereof is engaged by a catch 22 on a fixed pivot 24 to hold it clear of the pin 10 which assumes its outward position under the action of its spring and engages in one of the slots of the member 2 to effect a 90 degree rotation thereof on each revolution of the driving member 1. A cam projection 8 may be provided on the driving member which is adapted to engage and release the catch 22 after a movement of the driven member 2 has been effected. Alternatively an intermediate gear may be provided with a projection to trip the catch 22 and be actuated a tooth at a time by a striker on the driving member so that the driving pin 10 remains operative for a predetermined number of revolutions.

Title: Drive systems for lifts and hoists
IPC: B66B7/08
Filed: 1975-02-04
Abstract: 1442584 Elevation propelling arrangements JOHNS & WAYGOOD Ltd 4 Feb 1975 [5 April 1974] 4643/75 Heading B8L A traction drive system for an elevator comprises head and foot sheaves 1, 4 located in an elevator shaft, a rope 8 attached at one end 9 to an elevator car 3 and arranged to pass in turn over a floating sheave 2 mounted in a sheave frame 5 on the car, and over the foot and head sheaves, the other end of the rope 8 being attached to the frame 5, and means to apply drive to the rope 8 through either the head or foot sheave 2,4, or through a separate traction sheave, Fig. 3 (not shown), over which the rope passes. The frame 5 is slideably mounted in guides 6 on top of the car 3 and is biased upwardly by a spring 7. As shown, the head sheave 1 is the traction sheave, and the tension in the rope 8 between its point of attachment 9 to the car 3 and the point where it reaches the traction sheave 1 is equal to the weight of the car plus its load, ignoring the rope weight. The tension in the rope between the traction sheave 1 and the point of attachment to the frame 5 is twice the tension in the remaining part of the rope. As the car is loaded, the tension in the rope and therefore the available tractive force, is automatically increased. If the car 3 bottoms on a buffer 11 in the shaft, the tension in the rope is relieved, but the spring 7 extends to lightly tension the rope through the sheave 2 whereby a low tractive force is possible from the sheave 1 until the weight of the car again applies tension to the rope. If the car 3 engages an overrunning stop 10 at the shaft top, the rope tension be-. tween the frame 5 and the traction sheave 1 will momentarily increase with consequent decrease in the rope tension between the traction sheave and the attachment point 9 on the car, whereupon the tractor motor will either slip or stall depending on its available power output.

Title: Improvements relating to baby carriages and the like
IPC: B62B9/02
Filed: 1950-02-23
Abstract: 694,173. Perambulators; movement of vehicles up or down stairs. AVE TRANSPORTMITTEL HOLDING AKT.-GES. Feb. 23, 1950 [Feb. 23, 1949; Nov. 14, 1949], No. 4648/50. Class 108 (i) and 108 (ii). A baby carriage or the like with rockably arranged axles and in which each pair of wheels with its carrier arms is so supported as to be rockable about a fixed pivot on the carriage frame, is characterized in that at least one of the pairs of wheels in rocking relatively to the other pair of wheels effects a shortening of the wheel base and of the distance of its axle from the carriage to such an extent that the pairs of wheels come to rest on successive steps of the staircase with the carrying surface in a horizontal position. The carriage comprises longitudinal members 1 upturned at their ends and provided with pivot pins 2, 3 for a foot rest 4 and a back rest 5. Each wheel axle 11, 12 is mounted on arms 15, 16 respectively pivoted at 9, 10 to inverted U-shape bearing plates 7, 8, the upper extremity of the member 15 being extended rearwardly and twisted to act on a suspension spring 19. An arm 20 is mounted on each pin 10 adjacent each arm 16 and the two arms are interconnected by an adjustable rod 21 and urged apart by a further suspension spring 25, the combined arms being urged in an anticlockwise direction by a coil spring 26. For movement over level ground the arms 20 are secured to the plate 8 by removable pins inserted in aligned holes in the arms 20 and the plates 8. The side members of the back rest are articulated to arm rests 27 in turn connected by bows 29 to the forward end of the members 1, and adjustably connected to the foot rest 4 by a pivoted bow 32. The attitude of the interconnected back and foot rests may be adjusted by arms 46 formed with a plurality of notches 47 to engage lateral extensions of the pins 3. A guide bow 36, articulated at 37, may be secured in any desired position by a supporting arm 42. In normal movement over level ground the springs 19, 26 absorb any shocks and when it is desired to move the carriage over stairs the pins securing the arms 20 to the plates 8 are removed to enable the interconnected arms 16 and 20 to deflect in clockwise direction against the action of the spring 26 so that the rear wheels move forwardly and upwardly as the carriage is moved over a step with the seat in a horizontal position. In a further embodiment, Figs. 10 and 12 (not shown), the spring 26 and the removable pins are dispensed with and the arms 15 and 16 are interconnected by links. In normal level use the arms are held in a splayed apart condition against stops on the carriage frame but when the rear wheel of the carriage is pulled against a step it is urged forwardly and upwardly and the forward wheels are swung rearwardly and downwardly by the interconnecting links, the carriage body remaining horizontal. The carriage may be collapsed for travelling purposes, Fig. 6 (not shown), and the footrest 4 and backrest 5 may be lowered to provide a recumbent support, Fig. 1 (not shown).

Title: Method and apparatus for separation of components of a gaseous mixture
IPC: G01N30/58
Filed: 1960-02-10
Abstract: <PICT:0887293/III/1> <PICT:0887293/III/2> A gas mixture is continuously separated into two fractions by continuously moving an endless adsorbent packing (21, Fig. 4) in an unbroken path, introducing a purge gas into said packing (at point 24) releasing said purge gas at two points (25, 26) so located that the purge gas passes from one (25) to the other (26) in the opposite direction to the movement of the packing and introducing the gas mixture into said packing (at point 23) between said outlets and on the opposite side of the circuit to the purge gas inlet point, whereby the less strongly adsorbed fraction is recovered from the first mentioned purge outlet (25) and the more strongly adsorbed fraction at the second outlet (26). Preferably, a third outlet 27 is provided to remove purge gas passing through the adsorbent from inlet 24 in the same direction as the adsorbent.  An apparatus for performing this process comprises (Fig. 3) a rotatable shaft 2 carrying a disc 1 having an annular chamber 3 for the adsorbent packing; the chamber is provided with a large number of holes 4 arranged in a staggered circular row, and a cover plate 6 located by means of studs 8 with a similar row of holes 22.  A lower base plate 12 is provided with the inlets such as 23 and an upper cover plate 14 has outlets such as 26, 27.  To seal holes 4, 22, bearing rings 13, 15 of suitable plastic material are provided.  The assembly is clamped together by a number of bolts such as 16.  If so desired, the holes 4 or 22 may be absent and the inlets and outlets provided on only one cover plate.  The inlets and outlets may be equipped with throttle valves.  The gas sample is preferably mixed with a carrier gas such as nitrogen; the adsorbent may be a gas adsorbtion material or a pervious material coated with a liquid.

Patent GB-661470-A (GB)
Title: Apparatus for effecting self-regulated partial condensation of condensible vapors
IPC: G01N1/40
Filed: 1949-02-21
Abstract: In the analysis of steam for solid and gaseous impurities contained therein, the steam sample is split into two portions bearing a constant ratio to each other, one containing all the solid impurities, and the other containing all the gaseous impurities, the segregation of the impurities facilitating analysis.  The steam splitter 1 (Fig. 1) comprises a closed lagged vessel 5 to which steam from sample pipe 13 is supplied, and which contains a heat exchange tube 6.  Part of the incoming steam is condensed by tube 6 forming a condensate <PICT:0661470/III/1> <PICT:0661470/III/2> containing all the solid impurities, which together with the residual steam, now containing only gaseous impurities, is passed to a separator 2 where by means of a float operated valve 11, the condensate is separated and passed through condenser 12 for analysis of solids content.  The residual steam passes from separator 2 via valve 16 to a condenser 3 and through heat exchange tube 6 where it is re-evaporated thereby condensing part of the incoming steam, and finally passes via condenser 4 for analysis of gaseous impurities.  If a more highly concentrated solids containing fraction is desired to facilitate analysis, a bleed valve 19 at the entrance to tube 6 is opened to draw off a measured quantity of condensate thereby decreasing the flow thereof in tube 6 with a resultant decrease in the amount of solids containing condensate in vessel 5.  In a modification the splitter and separator are formed in separate portions of a lagged vessel as in Fig. 2 where steam enters at 32, passes through a coil 33 which reboils the solids containing condensate, passes to splitter 22 via pipes 35 and 36, and is in part condensed on a multi-coil heat exchanger 24, the gaseous fraction passing via pipes 28, 14 to condenser 3 for return to the heat exchanger at 25, and from thence to a condenser 4 via pipe 29. The solids-containing condensate passes through overflow 37 to separator 23 fitted with vent 38 and is drawn off as before.  In a further modification the coil 33 may be omitted and a baffle provided to prevent the incoming sample impinging directly on the heat exchange coils.
