Title: Apparatus for preventing the over-filling of a receptacle with material fed thereto
Inventor: HARRISON CHRISTOPHER ROLAND BO
IPC: B63B27/24
Filed: 1968-10-08
Abstract: 1283050 Fluid-pressure servomotor systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 8 Oct 1969 [8 Oct 1968] 47576/68 Heading G3P The over-filling of a receptacle, such as a compartment in a road or sea-going tanker, includes a valve 2, Fig. 1, whereby the flow of material is permitted or prevented by the presence or absence of a first fluid-pressure signal 7, a fluidic circuit 12 for permitting or preventing the presence of the first fluid-pressure signal in dependence on the presence or absence of a second fluid-pressure signal 14, and sensing devices 15 for permitting or preventing the presence of the second fluid-pressure in dependence on the level of the material in the receptacle being below or at a predetermined level. The valve Z is actuated by a piston 5 under the control of a relay valve 9 which is in turn controlled by the fluidic circuit 12 connected by a plug and socket 17 to the liquid sensing devices 15 in the compartments of the tanker. The line 10 applies pressure fluid to the relay valve 9 and to the fluidic circuit 12 through a pressure regulator 13. This fluidic circuit is shown in Fig. 2 and consists of two biased Schmitt triggers with their outputs 28, 38 connected through a passive AND gate 32 to the relay 9. When one of the sensing devices 15 opens a line 14 to atmosphere causing the bias on one trigger to switch the output to a port 27, the AND gate moves the relay 9 to a position in which the valve Z is closed. An indicator 29 is operated whenever the port 27 is pressurized and a second indicator 39 is operated and the valve 2 again closed if an abnormal rise in pressure in the line 14, which may be due to blockage, increases the bias on the other trigger. Each device 15 may be constructed as shown in Fig. 3 in which a valve 52 has inlets and outlets 56, 59 connected to the line 14 and a ball closure 53 is operated by a float 50 also connected with the line 14 through a tube 60. When the ball 53 is lifted, the line 14 is connected to vents 57. The device of Fig. 3 may be replaced by a spring-loaded single beat lift valve operated by a double diaphragm. A further alternative to the device of Fig.3 uses an O-ring seal operated by a double diaphragm to raise the pressure in the line 14 when the compartment has been filled to the required level. The plug and socket 17 provides both a fluid-tight seal and an electrical connection between the parts of the apparatus on the tanker and the parts carried by a gantry at the filling station.

Title: A method for the manufacture of hollow filaments
IPC: B29C48/05
Filed: 1964-12-02
Abstract: 1,067,689. Melt spinning hollow filaments. BEMBERG S.p.A. Dec. 2, 1964 [Dec. 2, 1963], No. 49077/64. Heading B5B. Hollow filaments of synthetic linear polycondensation products having, for example, the cross-section depicted in either Fig. 3 or Fig. 4 (not shown), may be made by melt spinning the product into a gaseous cooling medium through slot-shaped spinneret orifices, each of which slots has the form of, an open substantially rounded asymmetrical figure, the ends of each slot being spaced apart from one another in such a manner that they do not overlap. Examples of such slots are shown in Figs. 1 and 2. The melt extruded from one or both slot ends coalesces with the melt extruded from that portion of the slot which is opposite the two slot ends, to form hollow threads. A stream of the cooling gas is directed against the extruded filaments in a direction which is transverse to the path of travel of the threads and which coincides with line connecting on the spinneret face the gas between the two slot ends with the portion of the slot facing the gap, the slot ends of each slot not being in a direct line one with the other, the gaps between the slot ends of all the slot-shaped orifices facing in the direction from which the stream of cooling gas is supplied.

Title: Free fall circuit for hydraulic winch
IPC: B66D1/08
Filed: 1972-10-25
Abstract: 1371839 Controlling winches RUSTONBUCYRUS Ltd 25 Oct 1972 [26 Oct 1971] 49088/72 Heading B8B [Also in Division F2] A free fall operating circuit for an hydraulic winch includes a normally engaged hydraulically releasable free fall clutch 7 and a sensing valve 16 operable to de-activate the clutch release means in response to a pressure differential between the pressure and return lines 11, 12 for the winch motor 1, whereby free fall is prevented whilst the winch drum 2 is being powered in either direction. The clutch 7 is releasable for winch free fall by either manual selection or a lockout valve 15 whereby fluid is supplied from a pump 14 through line 17, sensing valve 16 and line 18, the valve 16 permitting the fluid to pass from line 17 to 18 only when in its neutral position. The valve 16 is operated by pilot pressure lines 25, 26 coupling the motor lines 11, 12 to opposite ends of the valve 16 and any difference in pressure between the lines 11, 12 causes the valve 16 to be displaced from its neutral position and exhaust the lines 17 and 18 the free fall condition of the winch only being selectable therefore when a hoist direction control valve 9 is in its neutral position. To prevent re-engagement of the clutch 7 during free fall movement, which is manually controlled by a foot brake, a solenoid operated safety valve 30 is inserted in the pilot lines 25, 26 and is controlled in response to the speed of the drum 2 and the pressure in the line 18 whereby the clutch 7 cannot be re-engaged due to a pressure differential in the lines 11, 12 while a free fall condition exists since the sensing valve 16 is isolated from the lines 11, 12 by the closed valve 30. A dashpot valve 33 restricts the fluid flow from the clutch operating ram to cushion the effect of reengagement of the clutch due to a power failure. The valve 15 is interlocked with the overall start circuit for the winch so that the winch circuit can only be completed when the valve 15 is in the "off'' position and the free fall condition is not existing. A self sustaining clutch brake arrangement is interposed between the motor and the drum.

Abstract: 1407760 Measuring roll and pitch of aircraft electrically JOHNS HOPKINS UNIVERSITY 24 Oct 1973 [27 Oct 1972] 49471/73 Heading G1N [Also in Division G3]  The invention utilizes the electrostatic potential field existing in the earth's atmosphere, which produces equipotential planes parallel to the earth's surface. A probe 12 Fig. 1 comprising a metal pad, preferably coated with a layer of radio-active material, is located at the tip of each wing of an aircraft 16 and connected to a voltmeter 14. If the aircraft is travelling with its transverse axis horizontal, the two probes 12 are at equal potentials and the voltmeter 14 indicates zero: if the aircraft is flying with its wing tips at different heights, the voltmeter output signal represents the angle of roll and may be used via a servosystem 18 to provide roll stabilization. Similarly two probes along the longitudinal axis of the aircraft are used to measure and control the pitch of the aircraft. In a combined use only three probes 12 are required Fig. 6 (not shown). Two additional probes displaced vertically may be used to measure the gradient of the electrostatic potential field, and to control the sensitivity of the roll and pitch measuring and control systems accordingly. In a further embodiment (Fig. 8) conductive rods 102 extending from each wing tip are interconnected by a circuit 104 which measures the current flowing between the rods when the aircraft changes its rod angle, this current being proportional to the rate of roll. Similar rods along the main axis may be used to determine the rate of pitch.
