Title: Improvements relating to systems for transmitting indications
IPC: G05D3/12
Filed: 1937-05-07
Abstract: 500,648. Electric signalling Systems. SPERRY GYROSCOPE CO., Ltd., HARDING, W. G., and NISBET, R. H. May 7, 1937, No. 13127. Divided out of 500,647 and 500,652. [Class 40 (i)] In a system for transmitting indications from a member which follows up a sensitive indicator (such as a gyroscopic or magnetic compass) the signals transmitted are corrected in respect of the lag in the following-up. In Fig. 3, a member 1 is controlled by means, not shown, to follow up a directional element 88. The lag is measured by means of a variable air-gap balanced transformer having a core member 96 on the element 1 and a soft-iron armature 95 on the element 88. A "selsyn" transmitter 2 is geared to the member 1 and two distributed field windings 98 and 99 are energized by the A.C. supply that supplies transformer 96 and by the output of an amplifier 97 respectively. The amplifier produces an amplified version of the output of transformer 96. The signals transmitted depend therefore on both the movement of the member 1 and the lag. In the modification shown in Fig. 4, the correction is not applied in the transmitter 2 but is applied in an auxiliary transmitter, the three windings 101, 102, and 103 of the stator being energized by signals from the transmitter 2 and the rotor 100 being energized by amplified signals from the transformer used to measure the lag. The transmission lines 3 are connected to the windings 101, 102 and 103. This correction may be applied to the transmission system shown in Fig. 3 of Specification 500,647 and in this case the transformer used to measure the lag also controls the follow-up motor as described in Specifications 417,995 and 480,115. Specification 500,652 also is referred to. Specifications 360,428, [Group XXXVII], 405,251, and 489,271, also are referred to in the Provisional Specification.

Title: A method of improving the flavour qualities of milk reconstituted from oxidized milk powder
IPC: A23C9/15
Filed: 1964-03-31
Abstract: 1,028,726. Reconstituting powdered milk. TETRA PAK A.B. March 31, 1964 [April 1, 1963], No. 13145/64. Heading A2D. The flavour qualities of milk reconstituted from oxidised milk powder are improved by subjecting the milk in course of reconstitution to such heat treatment as would normally lead to a denaturation of the proteins in the milk. The conditions under which the milk is heat treated may be selected to ensure that the end product will be sterilized. The heat treated milk may be packed in a package material, such as polyethylene film. impermeable to bacteria and of which the relative oxygen permeability, area and thickness are so chosen that denaturation products left in the milk after the heat treatment will be substantially oxidized by the permeating oxygen within a pre-arranged period of time.

Title: Improvements in and relating to vehicle bodies
IPC: B61F5/32
Filed: 1962-04-05
Abstract: 953,677. Railway vehicle bogies. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. April 5, 1962 [April 19, 1961], No. 13209/62. Heading B7L. A method of and apparatus for accurately mounting wheel pairs in the frame of a railway vehicle bogie with helical springs 20, Fig. 2, mounted directly between the axle bearing casings 21 and the bogie frame, and with spring blade links 22, 23 extending in longitudinal directions opposite to one another also between the axle bearing casings and the bogie frame, is characterized in that before the helical springs 20, Fig. 3, are inserted, locating devices 39, Fig. 6, are inserted between guiding sleeves 31a mounted accurately on the bogie frame in an upper spring plate 31 and a locating stud 35 on each axle casing 21, so that the spring blade links 22, 23 may be fitted without horizontal stress between the axle casings and the bogie frame, the springs 20 then being compressed and inserted in the sleeves 32 in place of the locating devices. For mounting the wheel pairs before the links 22, 23 are mounted, the bogie frame 1, Fig. 6, is jacked up and the wheel pairs placed beneath it. The locating devices 39 are placed on the centring studs 35 on one side of the bogie and the tubular part 31a of the upper spring- plae 31 is fixed without radial clearance over each locating device as shown. The bottom end of the part 31a rests on a flange 39c having a height which corresponds to one half of the permissible vertical spring movement shown in Fig. 3. On the other side of the bogie a somewhat similar but shorter locating device is placed over each stud 35, Fig. 7 (not shown), but such devices provide radial clearance with the studs, have no base-plates 39a, but still space the ends of the tubes 31a from the casings 21 a distance equal to one half of the vertical spring movement. The bogie frame is thus rigidly supported on the wheel pairs at a height which will permit the links 22, 23 to be mounted in an unstressed condition. The links at the ends which are attached to the bogie are adjustably clamped, Fig. 4 (not shown), and at their other ends are fixed to the casings 21, Fig. 5 (not shown), by eccentric bolts passing through sleeves. The springs 20 are then initially stressed by means of the upper and lower spring plates and inserted into the frame sleeves 32 as a complete unit. The other side of the bogie is then similarly fitted as described above. In operation the springs 20, Fig. 3, bear against plates 31, 33, and the lower plate 33 with its sleeve 33a is fastened by a screw 34 to the axle casing 21. Movements of the springs 20 are limited by abutment of the nut 36 with the plate 31 and by abutment of the lower end of the sleeve 31a with the plate 33. In Fig. 1 a crosshead 5 which is attached to the pivot of the vehicle body is connected to the bogie by rigid links 6, 7 and transverse longitudinally resilient links 8, 9. Plates 10, 11 secured to upper spring troughs 12, 13 are guided in the bogie by means of slide plates 14, 15.

Title: Improvements in or relating to methods of and apparatus for lixiviating solid materials with liquids
IPC: C13B10/10
Filed: 1954-05-10
Abstract: <PICT:0755360/III/1> <PICT:0755360/III/2> <PICT:0755360/III/3> A process for the lixiviation of solid material, especially vegetable material such as oil seeds with a liquid, comprises conveying the material upwardly along a helical channel, supplying the liquid to the upper part of the channel so that it flows downwardly through the material moving upwardly in the channel and causing fractions of the liquid to flow without passing through the material, from one series of points in the channel to another series of points therein which are spaced from the corresponding points in the first said series, whereby the speed of flow of the liquid in the channel and its time of contact with the material therein is controlled.  The unrestricted flow of fractions of the liquid within the spiral channel is brought about by (a) pumping liquid from a lower to a higher level, (b) allowing liquid to fall under gravity from a higher to a lower level, or (c) providing wire baskets for the material arranged in pairs so that one is raised from the liquid in the channel as the other is lowered into the liquid.  Apparatus in the form of a helical channel 1 is shown in Fig. 1, liquid is fed in the top of the channel through pipe 4a and the material to be extracted at the low end 5.  The material is subdivided into separate batches and is moved up the channel by rakes 2 fixed to linkage 3 connected to an endless conveyer belt. Fractions of the liquid are pumped back from a lower position 6 to a higher position 7 in the channel.  In a modification Fig. 4, the liquid enters the helical channel at 14 and the material is moved along by plates 12 (Fig. 5, not shown).  At grids such as 15, 17 and 19 liquid falls through the bottom of the helical channel on to the sections such as 16, 18 and 20 of the channel immediately below.  In a modification (Fig. 7, not shown) the material is held in wire baskets arranged in pairs.
