Abstract: 264,519. Leissner, H. F. Jan. 14, 1926, [Convention date]. Exhaust-silencers; two-strokecycle engines; cylinders, arrangement of ports in.-An exhaust box or silencer is divided by a partition 2 into two chambers 3, 4, and passages 11, 12 communicate respectively with the parts 13, 14 of the engine exhaust port, the passage 11 opening in front of a non-return valve 6 in the partition 2 and the passage 12 opening directly into the chamber 3, so that the pressure in the chamber 4 is higher than that in the chamber 3 and the exhaust pipe 15. As shown, the chamber 4 communicates with an ejector nozzle 17 in the exhaust pipe 15 from the chamber 3, the pipe 15 being provided with a throttle valve 21. The first portion of the exhaust is admitted by the valve 6 to the chamber 4, and the exhaust issuing from the nozzle 17 has an ejector action on the remainder of the exhaust escaping through the chamber 3. By fully or partly closing the valve 21 the pressure in the pipe 15 due to the ejector action may be made to return to the exhaust box after the ejector action is ended. The Specification as open to inspection under Sect. 91 (3) (a) states that the throttling of the pipe 15 causes a pressure wave in the exhaust box so that the cylinder is charged with air at a pressure above atmospheric; it also describes a modification in which the partition 2 is arranged horizontally, the valve 6 is replaced by a hinged flap valve normally closed by gravity, and the chamber 4 is uppermost and is covered with heatinsulating material. The exhaust pipe 15 may be replaced by an exhaust box with a throttle outlet. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in devices for the self-mooring of mines and buoys
IPC: F42B22/10
Filed: 1939-01-13
Abstract: 510,849. Submarine mines. OLMO, E. Jan. 13, 1939, No. 1175. Convention date, Jan. 15, 1938. [Class 9 (ii)] A mine or buoy is anchored in floating position or submerged to any required depth by a sinker comprising a fixed drum from which the mooring cable is paid out by a revolving arm located below the drum. The sinker a, when launched with the mine t, descends, leaving the mine on the surface of the water, the mooring cable, coiled on a fixed drum b, being paid out by an arm tr which revolves as the sinker descends. When a plummet s carried by a line fs, of any required length, from the end of a lever 1 touches bottom, the lever swings upwards under the influence of a spring m thereby lifting a plate pi linked by bars i to the lever into such position that jaws G carried by the plate are wedged by a cone M in the sinker to grip the cable and lock it to the sinker, after which the sinker descends carrying the mine with it. Bars as pivoted to arms bi secured to the arm tr, and urged towards the drum axis by springs mo, prevent the coils from slipping from the drum. In a modification, the plummet, on striking bottom, releases a lever e, Fig. 3, which arrests a toothed disc d supporting the jaws G by a plate pi and pins p. The continued rotation of the cone M raises the disc d by the action of the screw thread fh, thereby forcing the jaws G to grip the cable and lock it to the sinker. According to a further modification, the arrest of the toothed disc d, Fig. 5, by the release of the lever e when the plummet touches bottom, allows pins q carried by the cone M to align with vertical slots r in a sleeve n carried by the disc d, whereupon the sleeve is forced upwards by a spring v thereby causing the jaws G to grip the cable. Specification 383,178 is referred to.

Measuring intensity of cross-talk between adjacent lines.-An instrument for measuring crosstalk between the telephone lines comprises variable shunt and series resistances so proportioned as to obtain a non-linear scale and thus give substantially uniform accuracy throughout its range. Switches 2, 6 when in the right-hand position connect a source of sinusoidal voltage 1 to the disturbing circuit 3, the disturbed circuit 7 being connected to a detector or indicator D, giving an indication of the magnitude of the cross-talk. The switches 2, 6 are then changed over to their lefthand position, connecting the source 1 with the input of the cross-talk meter 5 and the indicator D to the output. The cross-talk meter 5 comprises series resistances R', preferably adjustable, and a shunt resistance R<3> connected across the input terminals. Adjustable shunt resistances R<1>, R<2> are connected as shown and are adapted to be simultaneously varied, as for example by mounting them both as slide wires on a single drum. The shunt resistances R<1>, R<2> are adjusted until the current indicated by the detector or indicator D approximates to the current set up therein when the source 1 is connected to the disturbing circuit and the detector D to the disturbed circuit. From the values of the resistances the ratio of the cross-talk power to the power in the disturbing circuit is found.

Abstract: 1427791 Container filling apparatus AEROJET-GENERAL CORP 11 Jan 1973 [25 Jan 1972] 1461/73 Heading B8T Apparatus for filling hollow cylindrical rocket chambers 17 with propellant slurry which is subsequently solidified within the chamber by curing, comprises means for forming axial bore holes within the slurry prior to the latter solidifying, the means consisting of a plurality of cylindrical rods 71, each of which may be inserted into a chamber 17 either before or after the latter is filled with slurry. A pluralty of rocket chambers 17 are each mounted upon a rotatable table 12, the axis of each chamber being maintained vertically by means of a stud 16, integral with a lower support member 14 mating with a corresponding recess in the base of each chamber. Table 12 is rotated until each chamber 17 is situated beneath a filling head 38; the table is then raised until the upper end of each chamber has entered its corresponding filling head, after which the chambers are evacuated, sealing means being provided by annular bladders 47 which are embedded in the inner walls of each filling head and which are expanded by air pressure until they attain sealing engagement with the chambers 17. A pipe 27 receives slurry from a reservoir (not shown) and passes it into a manifold 28 which communicates via a plurality of valves 30, 37 and pipes 29, 34 with chambers 17. With valves 37 closed and valves 30 open, the slurry is drawn through manifold 28 into a plurality of cylinders 31 by means of pistons 32. After the required amount of slurry has entered the cylinders 31, a magnetic switch is tripped, valves 30 close and valves 37 are opened. Pistons 32 then inject the slurry into chambers 17. The top of each chamber when in sealing engagement with its corresponding filling head, engages a frustoconical seating member 41, the end wall of which is perforated to allow the slurry to enter the chamber in the form of strands, thereby minimizing the chance of gas bubbles becoming trapped within the chamber. Once the chambers are filled to the required level, the vacuum within each is destroyed and they are disengaged from the filling heads. The table 12 is then rotated to bring each chamber beneath a rod 71, each rod being attached releasably to shoulder 70, which is free to move under power in a vertical direction. The holders are displaced downwardly, thereby causing rods 71 to enter their respective chambers 17 and the slurry contained therein, the rods are then released from the holders 70 and the chambers removed from table 12 prior to the slurry being cured. Once curing has taken place, rods 71 are removed. In an alternative method of filling the chambers, rods 71 may be placed within the chambers prior to the latter being filled; filling taking place in an identical manner to that described above. Drip trays 54, may be placed beneath filling heads 38 subsequent to the filling of chambers 17.
