Title: An improved method for pulling down pit-props or pillars and means therefor
IPC: E21D15/60
Filed: 1937-12-22
Abstract: 504,955. Collapsing pit props, and pillars. MOLL, F. W. Dec. 22, 1937, Nos. 35528, 35529, 35530, 35531, 35532, 35533, and 35534. Convention dates, Dec. 28, 1936, Feb. 12, 1937, March 20, 1937, March 20, 1937, March 20, 1937, April 29, 1937, and April 30, 1937. [Class 78 (iii)] [Also in Group X] A row of pit props or pillars each constructed of at least two parts are collapsed in succession by a wedge or striker on a rope which passes through guides provided on one part of each prop or pillar in the row so that when the rope is drawn forward, as by a winch, the wedge or striker causes or permits relative movement of the parts of each prop in succession and thereby their collapse. Two parallel rows of props may be collapsed in staggered order, according to the direction of cracks or faults in the supported way, by the use of two ropes with wedges wherein the wedge on one rope is in advance of that on the other so that the props which are simultaneously collapsed are in the line of the crack or fault. Further, the ends of two such ropes carrying wedges may be connected beyond the wedge so that as they are drawn along they will pull away auxiliary props between the two rows of main supporting props. An auxiliary rope detachably engaging each prop may be associated with the rope for hauling the wedge to draw away these parts after collapse, and the parts of each prop may be loosely connected together so that the whole of each prop is drawn away by the auxiliary rope. Fig. 8 shows a prop comprising a metal part 1, a wood part 12 with crown plate 15 and a part 2 engaging the part 1 at an incline and providing a guide for the wedge secured to a rope 5 by which the parts 1, 2 are forced down the incline to collapse the prop. Fig. 7 shows a prop with the engaging portions 13 of the parts 1, 2 correspondingly curved, preferably spherical with an incline 14 on the part 2. Figs. 9 and 9b. show a pillar built up of pieces of wood or iron 1<1> placed crosswise and includingmembers 7<1> resting oil steep inclines 31 of a member 19 but prevented from sliding off by rope loops 20 engaging pivoted hooks 21. The pillar collapses when a striker 61 drawn along by a rope 5 engages extensions 23 of the hooks and disengages the hooks, from the rope loops. In a modification, the rope loops engage pins on the member formed with inclines and are forced off these pins by a wedge on a draw rope. In all cases the part of the prop or pillar on which the wedge acts for collapsing may have guiding projections to lead the wedge into operative position. In Fig, 11. the rope 5 for drawing the wedge 6 to collapse the props 1 is associated with a lighter rope 30 with which the wedge-actuated part of each prop is detachably engaged and which is drawn along, as by a winch, to carry away the parts on collapse of the prop.

Title: Improvements in or relating to the preparation of phosphoric anhydride and phosphoric acid
IPC: C01B25/20
Filed: 1930-11-29
Abstract: Phosphoric anhydride and phosphoric acid are obtained by the combustion of phosphorus with oxygen containing gases such as air, with or without the presence of water, the molten phosphorus being mechanically converted into a finely-divided condition with the aid of moving comminuting members such as rapidly-rotating discs or cones or revolving percussion apparatus.  The molten phosphorus may pass through a vertical hollow shaft on to a horizontal rotating disc or may impinge directly on to the centre of the disc.  The combustion air may be employed to cool the disc, for example it may be introduced into the lower portion of the combustion vessel so that it first flows round the lower surface of the disc and then rises round the edge of the disc. Further, the disc may be caused to rotate in a funnel-shaped casing the atomized particles only coming into contact with the combustion air above this casing.  The spraying disc may be provided with an upwardly bent edge, the resulting phosphorus mist forming a cone open at the top.  Water as well as phosphorus may be fed on to the disc, phosphoric acid of any desired concentration being obtained.

Abstract: 1317934 Modulating light AMERICAN OPTICAL CORP 28 July 1970 [24 Sept 1969] 36465/70 Heading H4F Each of two transducers arranged in series along an optic fibre applies a compression across a different diameter of the fibre (as described the diameters are at 90 degrees to each other) to produce birefringence thereat so that a beam of plane polarized coherent light transmitted along the fibre and then through an analyser is independently modulated in phase and amplitube. If the transducers apply equal compressions of opposite sign, the fibre becomes birefringent, but the phase of the output light is unchanged, while if the transducers apply equal compressions of the same sign, the fibre remains optically isotropic but the optical path length and thus the phase of the output light varies. Any combination of compressions can be resolved into these sum and difference components, and therefore the phase and amplitude modulations may be made independent. Since it is not practical to apply a negative compression, the transducers are biased to apply equal positive compressions and are operated about the bias point. The transducers may be magnetostrictive rods or hydraulic pistons, but only piezoelectric crystal transducers are shown and described in detail.

Abstract: 1,273,636. Combine harvester. MASSEYFERGUSON Inc. 21 July, 1969 [22 July, 1968], No. 36524/69. Heading A1F. [Also in Division G3] The rate at which grain is "lost" in a combine harvester is kept constant by regulating the speed of travel of the harvester in response to a signal obtained by measuring the loss. The measurement is made by detecting (by electronic circuit 17 .. 28) the rate at which grains impinge on a microphone 13 placed at the end of a straw walker 11. (These are the "lost" grains). The microphone is insensitive to the straw. The measurement is indicated on a meter 25 and also energises one winding 29 of a differential electrohydraulic valve. The other winding 37 is energised from a manually adjusted source 41, 43. Any misbalance is due to the flow rate of the lost grain being too high or too low and effects adjustment of a variable speed pulley 3 between the engine 1 and the driving wheels 7 of the harvester.
