The falling matrices are arrested by a platform j of wood &c. to diminish rebound, or may fall on to the end of the plunger before its retraction, and then on to the platform. The plunger is retracted by a cam L<o> on one of the distributor-screws, and is advanced by a spring n.
Patent GB-700775-A (GB)
Title: Improved process for separating mixtures of fatty acids
IPC: C11C1/00
Filed: 1951-03-22
Abstract: Mixtures of fatty acids are separated into solid and liquid fatty acids from the solid mixture obtained by solidifying a fatty acid melt by washing it, in a more or less finely divided condition, with a solvent at a constant or slightly increasing temperature.  The more unsaturated acids are dissolved out and the solid or more saturated acids left.  The latter may be freed from the mother liquor by usual filtration or centrifuging.  Any suitable polar or non-polar solvent may be used; gasoline, dichloroethane, and methyliso-butylketone are exemplified.  The solidified melt may be finely divided by milling, spraying or by rapid cooling of the molten fatty acid mixture.  If the melt contains a high proportion of unsaturated fatty acids, milling may not be possible.  In such cases it is sufficient to divide the mixture into relatively coarse lumps which, after treatment with the solvent, disintegrate into a finely divided mass. The treatment is effected preferably at room temperature.  A lower temperature may be used if the melt is liquid at room temperature. Preferably, for each part by weight of the fatty acid mixture about three parts by weight of the solvent are used.  The solvent used may consist of the mother liquor obtained in a previous treatment, which may be re-used a number of times.  The process may be applied to the separation of mixtures of fatty acids which have previously been pressed, preferably mixtures containing at least 90 per cent. of stearic acid and palmitic acid.

Title: Improvements in the preparation and reproduction of maps, plans, or drawings
IPC: G03C5/10
Filed: 1943-05-04
Abstract: 566,117. Luminescent materials. KODAK, Ltd., and COPPIN, F. W. May 4, 1943, No. 7001. [Class 39 (i)] In a map, plan, or drawing composed of two or more sets of details, two sets are formed of inks which have their maximum light absorption in different regions of the visible spectrum, and the ink of at least one of the sets contains a substance which, when illuminated by fluoractivating light fluoresces light of the colour of that for which the other has maximum absorption. When reproducing such maps and plans, they are illuminated by white light and ultra-violet light and the reflected light is passed through a primary colour filter. The fluorescence enables satisfactory suppression of one of the sets to be obtained even though it may absorb some of the light for which the other set has maximum absorption. Specifications 542,006 and 556,144 are referred to.

Title: Improvements in or relating to the Gyroscopic Steering Mechanism of Automobile Torpedoes.
IPC: F42B19/06
Filed: 1917-05-16
Abstract: 127,662. Whitehead Torpedo Works, Ltd., and Lees, E. May 16, 1917. Torpedoes, locomotive.-Relates to gyroscopic .steering-apparatus of the kind adjustable in azimuth for " angle " steering, and consists in the provision of a pointer for indicating whether the torpedo will turn to right or left, and interlocking- arrangements between this pointer and the dial which indicates the " angle " to which the torpedo will turn, in order (1) to lock the dial in the zero position when the pointer is in the neutral position, (2) to allow the dial to be adjusted in the direction indicated by the pointer only, the dial having to be brought back to zero before adjustment in the other direction can be made, and (3) to allow visibility of one of two dial scales only at a time, namely, that corresponding to the direction given by the pointer. In the form shown in Figs. 1 and 2, the direction pointer a is geared by a segment and rack to a slide b provided with windows b<2>, b<3> for uncovering one scale or the other of the dial A, according to the direction to which the pointer is set. In the form shown in Fig. 3, the pointer a carries two pins d, e adapted to be brought into concentric grooves d<1>, e<1> on the underside of the dial through approaches d<2>, e<1> respectively. This arrangement locks the dial in the zero position when the pointer is in the zero position, and allows adjustment in the direction to which the pointer is set only. In a modification, the pointer is linked to a radially movable escapement for the same purpose. The pointer is brought back to zero by a spring plug as soon as the dial is brought back to zero. Where two or more indicating-dials are used, for example as described in Specification 126,689, the indicating- dials are geared to a separate dial provided with an escapement controlled by the direction pointer.

Title: Improvements in or relating to ultra-high-frequency generators
IPC: H01J25/06
Filed: 1941-06-11
Abstract: 561,199. Electron oscillators. AKT.- GES. BROWN, BOVERI, & CIE. June 11, 1941, No. 7404. Convention date, Feb. 28, 1940. [Classes 39 (i) and 40 (iii)] In a velocity modulation tube both the input modulator and the output inductor are pairs of electrodes with attached antennµ so situated within the same wave guide that the amplitude of the high-frequency voltage at the modulator is smaller than that at the inductor. In the form shown, an electron stream from gun 2, 3, 4, Fig. 1, passes through modulator grids 6, 7 and after bunching delivers energy to inductor grids 9, 10, finally falling on collector 11. Grids 6, 7, 9, 10 are supported from the walls of the wave guide 32 by narrow antennµ 14 ... 17. Waves emitted by antennµ 14, 15 towards end wall 4 are reflected to form standing waves, from which antennµ 16, 17 pick up a reduced feed-back voltage. The vacuum space is closed by a dielectric disc 35 at a distance from grids 9, 10 equal to their distance from the end wall 4, so as to minimize dielectric and reflection losses. The waves generated in the guide may be radiated into free space from a horn, or the further end may be metallically closed and a voltage picked up by an antenna for transmission through a coaxial line. When the wave is of H1 type, antennae 14, 15 are collinear and parallel to antennµ 16, 17 ; the collector 11 is supported by rods at right angles to these to eliminate pick-up from the electric field. This type has a high transverse electric field in the centre so that undesirable deflection of the beam may occur. This is avoided by using H2 or higher type waves in which the central field is small. With an H2 type the lines of electric force are as shown in Fig. 9 and the grids are supported by double antennae 14, 14<1>, Fig. 7, and 15, 15<1> at right angles, the collector support rods being placed at 45 degrees to these. The antennµ may carry cooling pipes for the grids, or the whole of the guide 32 may be cooled by liquid.

Title: Improvements in and relating to grabs
IPC: B66C3/08
Filed: 1923-03-14
Abstract: 217.636. Barnard, D. J. March 14, 1923. Grab-buckets.-Relates to single-chain grabs of the type in which the buckets are held closed by gravity catches engaging a pin on the lower cross-beam and fall open automatically when the catches are released. Hooks &c. 18 are provided on the grab-head co-operating with a discharging ring 19 to permit a partial opening and closing of the buckets with the grab supported by the ring. The hooks &c. 18 are released from the ring by the movements of the lower sheave-block on hauling in the chain. As shown, the grab comprises upper and lower sheave-blocks 15, 13 kept in alignment with the lower cross-bar by telescopic rods 9, 10 which are mounted on the top cross-bars 6, 7 and on the cross-beam respectively and pass through sleeves 12 on the lower sheaveblock. The lower sheave-block carries a gravity catch 27 which engages a pin 28 on the lower cross-beam. The hooks 18, Fig. 6, are pivoted on the upper sheave-block and are normally turned inwards by a weight 22 which rests on the short arms 20 of the hooks. When the closed grab is hauled up to the ring 19, the hooks take over the ring so that on lowering, the grab is supported. The brackets may then be opened and closed by manipulating the chain, see Fig. 3. To release the grab from the ring, the chain is hauled in, the lower sheave-block engages and lifts the weight 22, and the grab is lifted from the ring with the hooks 18 turned outwards by their own weight. In a modification, the hooks turn inwards by their own weight, and hava downward extensions which are engaged by buffers on the lower sheave-block to turn the hooks outwards when the grab is to be lifted from the ring. In another modification, the weight 22 is replaced by spring-actuated rods on the upper sheave-block. When the grab is suspended from the ring the buckets may be released from the lower sheave-block and allowed to open freely by paying out the chain until the gravity catch 27 engages an arm 29, 30 pivoted on the grab-head and releases the pin 28. In a modification, a bell-crank lever is pivoted on the lower sheave-block and engages at one end with a projection on one of the spreader arms 8 and at the other end with the gravity catch 27. Specification 187,060 is referred to.

[Also in Groups IX and XXII] Sliding-clasp fasteners of the type comprising interlocking coils of filaments (see Specifications 548,819 and 547,663 [both in Group XXV] and U.S.A. Specifications 2,541,729 and 2,541,728) are made by winding two filaments F1, F2, Fig. 15 in opposite directions around a tapered mandrel M, the loops of F1 alternating with and nestling between the loops of F2. Each coil of a winding is laid with a loop thereof over a corresponding loop of the preceding winding lying on the mandrel, while the remaining part of the first-named winding lies beside the remaining part of the second-named winding. The loops are drawn tightly around the mandrel and push the preceding loops along the mandrel and on to a mandrel extension 66 where they are heated in a device H, Fig. 1, to fix them in a permanently coiled form. The interlocked coils travel along the mandrel extension 66 (which is a wire) through curved guides 102 and are taken off at the end 67 of the mandrel. The mandrel is elongated, so that elongated coils are formed. The cross-section of the filaments is semi-circular. The filaments may be of polyamide, polystyrene, P.V.C., cellulose acetate or rubber. The machine shown comprises two spools 25, 30, Fig. 2 (plan view) from which the filaments F1, F2 pass upwardly and under tension to the mandrel M. Spool 25 is secured to a sleeve 22 which rotates clockwise about a centre 17. Spool 30 is secured to a partannular pinion 32 which is disposed above the sleeve 22 and rotates counterclockwise about a centre 31. There is a gap in pinion 32, between G1 and G2, and the post 23a that supports spool 25 and enters and leaves the gap once during every revolution of the post. The (stationary) mandrel is secured to an arm 57 extending from a post 56 disposed between the two centres 17 and 31. Sleeve 22 and pinion 32 are driven from motor 44, which drives also coil take-off rollers 98, 101. The filaments leave the spools by way of a tensioning arrangement (see Group IX).
