Patent GB-609765-A (GB)
IPC: B64D17/38
Abstract: 609,765. Parachute fastenings. QUILTER, J. R. C. March 21, 1946, No. 8791. [Class 4] [Also in Group XXV] A detachable connector for parachute harness, adapted for manual disconnection of lift webs and like connections, while under tension, comprises two normally parallel crossbars 10, 11 to which the adjacent ends of the tensile connections 12, 13 are attached, two side-pieces 14, 15 in which the extremities of the crossbars are engaged, and two spring- controlled grips 16, 17 displaceably mounted on the side-pieces, these grips being adapted for sliding longitudinally of the respective sidepieces in order to unlock one of the crossbars 11, and then closing each towards the other in order to release one extremity of the other crossbar 10, so that it can swing around a pivot 19 at its opposite extremity and allow the end of the tensile connection to slip off. The side pieces 14, 15 are of substantially square cross-section and are engaged by the channel-section grips 16, 17, pins 19, 20 in the side pieces engaging L-shaped slots 18 in the grips. The upper crossbar 10 is in the form of two semi-cylindrical members 23, 24, Fig. 4, the former of which has at one end a knuckle 21 with a slot 26 engaging the pin 19, and the other end engages a shoe 28 fixedly engaging the second pin 20, while the knuckle 22 of the member 24 fixedly engages the pivot pin 19 and the other end is formed with a tooth 33 engaging a corresponding tooth 32 in a shoe 29 formed with a slot 31 engaging the pin 20. The lower crossbar 11 comprises an outer sleeve supported by two hollow trunnions 43, 44, Figs. 3 and 5, which, inside the sleeve are cut to semi-annular section, the two cut-away portions 43a, 44a overlapping and being slidable relatively to one another longitudinally. Trunnion 44 is formed with a circular extension 45 with a rounded end 46, and houses a sliding rod 50, also formed with a rounded end 51, a spring 56 being mounted between the members 45 and 50. These members engage blades 35, 36 against which bear springs 41 housed in the side-pieces 14, 15. To effect release of the lift webs 12, the grips 16, 17 are first slid longitudinally against the springs 41, to disengage a hook connection 49, Fig. 3, between the members 35, 45, and are then squeezed together to bring the side-pieces 14, 15 into engagement with the bases of the channels 16, 17. The slots 26, 31 permit sliding of the member 23 and shoe 29, with consequent disengagement of the teeth 32, 33 to allow the crossbar 10 to pivot about the pin 19 and release the cords 12, Fig. 2. The inward movement of the grips 16, 17 causes similar movement of the extension 45 and rod 50 against the spring 56, the trunnions 43, 44 and the ends of the side-pieces moving apart to loosen their support of the outer sleeve 11, the side-pieces thus being left free to rock slightly, to facilitate release of the crossbar 10, - and to make possible its re-engagement after the lift cords 12 have been replaced.
Patent GB-1302040-A (GB)
IPC: B22D11/22
Filed: 1969-12-30
Abstract: 1302040 Continuous casting USS ENGS & CONSULTANTS Inc 30 Dec 1969 [31 Dec 1968] 63373/69 Heading B3F [Also in Division C7] In a method of controlling heat transfer to or from an elongated object (such as a steel strip to be heated or a cast strand to be cooled) passing continuously from one point to a station where heat is transferred, for each of a number of increments of length, the time to travel from the point to the station is measured and the heat transferred at the station to or from each said increment is controlled according to the elapsed time for the increment to obtain a desired heat transfer rate. A continuous strand C is drawn for cooling, past spray stations 8, 10 by withdrawal rolls 4 and, as each increment 1-36 (say six inches) of length passes through the rolls, a generator 16 passes a signal to a digital computer 20 having 36 memory cells, cell 1 corresponding at any time to the increment leaving the mould 2 at that time and cell 36 to the increment leaving the rolls. If the strand speed is 72 inches/min., i.e. twelve increments/min., a time of 5 sees. for each increment is impressed temporarily and successively on each cell, i.e. as each relates to the position of the corresponding increment. If the speed is then halved, 10 sec. times are so impressed and follow the 5 sec. impressions in their progression down the computer memory section 24. When the leading end of the strand C, i.e. increment 1, reaches the middle of spray station 8, the computer calculates the time elapsed since it left the mould, i.e. the sum, viz. 75 sees., of the times in cells 1-15 at that moment. A valve 12 will then be controlled by the computer accordingly. Similarly, when the strand end reaches the middle of spray station 10, a valve 14 is controlled according to the time total, 135 sees., of the cells 1-23. The cooling rate may be modified by the surface temperature of the casting, detected by sensors 28, or by the time the metal resides in the mould 2 before leaving it. Alternatively, memory cell 1 may record the total elapsed time since the start of withdrawal from the mould 2, with the contents of each other cell, as before, being replaced by the contents of the next preceding cell at each signal from the generator 16. In another embodiment, with a single spray station (34), a preset counter (30) accumulates the generator pulses and passes on a signal when the number of pulses represents a desired strand increment, e.g. six inches.

Title: Fluid flow measuring apparatus
IPC: G01P5/01
Filed: 1978-08-10
Abstract: A fluid flow meter, for example for measuring the velocity of an air flow, comprises a flow duct 20 having a transverse vortex-shedding bar 22, and ultrasonic or other detector means 23, 25 for sensing the shedding of Karman vortices from the bar as the fluid flow passes the bar, and means 51, 60 for converting the alternating output signal of the detector means into a signal of square-wave form for operating a digital counter 63, and one or more additional cross-members 30 extending across the flow duct downstream of the flow section where the vortex-sensing means operates, the additional cross-member 30 extending transversely to the vortex-shedding bar 22 and being of cylindrical or aerofoil cross-section, or of rectangular or other cross-section having a flat upstream face parallel to the bar 22. The provision of the additional cross- member 30 is found to improve the regularity of the vortex-shedding from the bar 22 and hence the accuracy of the meter reading. <IMAGE>
Patent GB-2013941-A (GB)
Title: Apparatus and method for determining characteristics of subsurface formations
IPC: G01V1/28
Filed: 1978-10-09
Abstract: The determination of a "composite" parameter of the formation water in formations surrounding a borehole, for example the composite conductivity of the formation water, is used to obtain a relatively accurate determination of formation characteristics, such as water saturation. The determined values are meaningful even in shaly regions of the formations. In contrast to past approaches which attempted to determine the volume of shale or clay present in the formations and then introduce appropriate factors which often involve substantial guesswork, the disclosed technique determines a composite water parameter, for example a composite water conductivity, which represents the conductivity of the bulk water in the formations, including both free water and bound water. Bound water trapped in shales is accounted for in this determination, so unlike prior techniques, the shales can be considered as having a porosity. Having determined the composite water conductivity, water saturation can be directly obtained using relatively straightforward relationships which do not require estimates of the volume of shale in the formations. Shale effects are accounted for by the different conductivities (or other parameter such as capture cross sections) of the formation water constituents (free and bound) which make up the total water. In apparatus for determining the composite conductivity of the formation water in formations surrounding a borehole, a first quantity is derived as being representative of the free water conductivity in the formations. A second quantity, representative of the fraction of bound water in the formations, is also derived. A third quantity, representative of the conductivity of the bound water in the formations is also derived. The composite parameter is then determined as a function of the first, second and third quantities.
