Title: Improvements relating to follow-up systems for gyro compasses and other sensitive instruments
IPC: G01C19/38
Filed: 1930-05-08
Abstract: 345,552. Gyroscopic compasses. HILLIER, A., 15, Victoria Street, London. -(Sperry Gyroscope Co., Inc. ; Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.) May 8, 1930, No. 14143. [Class 97 (iii).] In a follow-up system for gyroscopic compasses or other sensitive instruments, the actuating member responsive to relative movements between the sensitive and follow-up elements comprises a transformer having one winding attached to one of the elements and supplied with alternating current, and the other winding attached to the other element so that relative movement between the two elements causes the second winding to include more or less of the flux generated by the first. The follow-up element is driven by means actuated from the second winding. In Figs. 1 and 2 the follow-up ring 6 of the compass carries a frame 18 provided with pole-pieces 14, 14<1> having windings 15, 16 supplied with alternating current from the supply by which the rotor of the gyroscope is driven. A fixed magnetic path for the lines of force between the poles is provided by a soft-iron core 17 fixed in the frame 18. The vertical ring 4, in which the gyro-casing 1 is pivoted, carries coils 19, 20 which extend between the core 17 and the members 14, 14<1>, the coils being so disposed that the E.M.F.'s induced in them are equal when the rings 4, 6 are co-planar, but become unequal when relative movement in azimuth between the two rings occurs. The coils 19, 20 are utilized to control the follow-up motor 11. Alternatively the coils 19, 20 may be connected to a relay effecting the closure of the field circuit, the direction of the field current depending on which of the coils has the greater induced E.M.F. A form of relay which avoids the making and breaking of contacts in the open air is shown in Fig. 3. A sealed tube 31 containing mercury &c. 32 has within it a pair of magnetic cores 33, 34 pivoted at 35. Coils 241, 251 in circuit with the coils 19, 20 are placed round the parts of the tube containing the cores so that when, for example, the coil 24<1> is more strongly excited than the coil 25<1>, the core 33 is pulled down and the mercury rises in the part 36 of the tube 31 and completes circuit between the points 38, 38<1>, the field circuit of the motor 11 being thereby energized in the appropriate direction.

Title: Improvements in or relating to footwear-counter-stiffener moulding apparatus
IPC: A43D11/12
Filed: 1962-04-13
Abstract: 941,456. Loaders for counter stiffener moulding machines. H. G. SCAMMON April 13, 1962 [April 14, 1961], No. 14357/62. Heading A3B. In a counter stiffener moulding machine having spaced relatively movable male and female mould parts, a loader, 18, upon which the stiffener blank is mounted and held in shape to be placed astride the male mould, is movable to and from the mould parts and comprises a support 36 on which is mounted spaced pairs of fingers 46, 48, to hold the stiffener blank with the central portion arched between the fingers, and a gauge 66 which is situated on the support between the fingers for engagement with the arched portion and which is rotatable towards one side or the other to adjust the length of the ring at that side. As disclosed a pin 70 (Figs. 3 and 4) attached to a flange 68 of the gauge 66 engages a notch in the counter stiffener blank. By rotating the gauge to one side the length of the wing of the stiffener on that side is increased and hence stiffeners can be moulded for left or right shoes. The gauge can pivot around a bolt 80, in a slot 67, screwed to a block 75 which is fixed to a slide 72. The latter can slide on the back side of the supporting plate 36 between guides 74 and is fixed by a bolt 40 through a slot 82 to the plate 36. Springs 88 normally urge the slide 72 and thus the gauge 66 upwards but the gauge is displaced downwards when the mould parts close on to the stiffener blank. On the front face of the plate 36 (Fig. 3) outer fingers 46 and inner figures 48 are pivotally mounted on screw bolts 50 and a stud 61, respectively, and are capable of lateral movement. A spring 64 presses the inner figures outward while screws 60 acting on metal plates 62 on rubber blocks 54 prevent the outward movement of fingers 46. To adapt the loader for stiffeners with exaggerated curves at their ends, the lower parts of the plate 36 have convex surfaces 90. Screws 92 adjust the position of the loader relative to the mould parts. The supporting plate 36 is attached by a bolt 40 to a plate 24 secured to the ends of two arms 20 which are pivoted to the male mould. Bolts 28 screwed to the plate 24 have cone shaped tips fitting in recesses 38 in the plate 36 so that the position of the plate can be adjusted. Specifications 898,725 and 898,726 are referred to.

Patent GB-762092-A (GB)
Title: Process for improving the flow properties of thermosetting resin moulding compositions
IPC: C08J3/00
Filed: 1953-05-22
Abstract: The flow of heat-hardenable synthetic resin moulding compositions is improved by subjecting the compositions to the vapour of a solvent which swells the resin and which has a normal boiling-point below 100 DEG  C.  By this means it is possible to advance the cure of the resin to a greater degree before moulding and hence reduce the final curing time, and still obtain satisfactory flow, or to reclaim moulding materials that would otherwise have been too far advanced, or to reduce the resin content of the moulding composition.  The treatment is preferably carried out in a vessel which is evacuated and into which the solvent vapour is carried, e.g. by an air stream bubbling through the solvent in an attached vessel, and is continued until the moulding composition has taken up from 0.5 to 3.5 per cent of its weight of solvent or until beads of solvent appear on the surface. After treatment the material may be stored without loss of solvent.  In an example an over-hardened wood-flour filled phenolaldehyde moulding composition is spread out in a vacuum container and is subjected to a vacuum of 20-30 mm. mercury absolute. The container is then connected to a vessel containing acetone and a stream of air bubbling through the acetone carries the vapour into the container.  After a few seconds beads of acetone form on the moulding material and the acetone is then disconnected and the remaining vacuum of about 200 mm. absolute, broken.  The temperature of the acetone was about 8-12 DEG  C. higher than the moulding powder.  The flow time of the heated powder in a beaker mould was 10.8 seconds compared with 51 seconds for the untreated powder. Specification 747,969, [Group III], is referred to.

Title: Improvements in or connected with the lubrication of fluid pressure engines and the like
IPC: F01M1/06
Filed: 1922-05-23
Abstract: 202,083. Hounsfield, L. H. May 23,. 1922. Oil, removing.-In fluid-pressure engines and the like in which variations of fluid pressure occur, means are provided to ensure that the ends of the bearings at which lubricant leakage is liable to occur are subjected to the phases of low pressure and not to the phases of high pressure, and the lubricant that is prevented from escaping is used in another part of the engine. As shown in Figs. 1 and 2, for a two-crank engine, a radial hole H in the crank shaft is always open to the crank chamber, but communicates by passages K, L with an annular groove M in the outer end of an outer bearing only when the crank chamber is at suction pressure, i.e. when the hole H registers with a groove J in the bush A of the middle bearing. When the crank chamber is at suction pressure lubricant flowing along the outerbearing is sucked through the passages K, L into the middle bearing A. An air vessel O opening into the passage K may be fitted to make the suction continuous in its action. The lubricant may be supplied to the end bearings by means described in Specification 196,091 and the invention may be adapted to deliver lubricant to thesame bearing from which it is drawn.
