Title: Improvements in apparatus for submarine sound signalling
IPC: G10K1/068
Filed: 1925-12-24
Abstract: 268,042. Gardner, W. Dec. 24, 1925. Subaqueous audible signals. - In apparatus for subaqueous signalling wherein a sounding body is excited by the blow of a hammer actuated by a spring or other elastic means released intermittently under the control of a fluid pressure operated piston, means are provided for initiating automatically the supply of motive fluid. In the form shown in Figs. 1 and 2, the operating means comprises a cylinder 8 and piston 9 with a known automatic valve gear (not shown) operated by the piston to control admission and exhaust of the fluid to and from both ends of the cylinder. The end 8<b> of the cylinder communicates through a valve 30, Fig. 9, with a supply reservoir 33. The valve 30 is restrained from opening under the action of a spring 31 by an electromagnet 32. The wiring is arranged to cover a large surface of the submersible vessel so that in the event of an accident the breaking of the circuit by permitting the valve to open initiates the supply. The piston rod 9 has a cross-head 10 to which is connected one end of a spring or springs 6 the other ends of which are attached by extensions 4 to the hammer 3. Movement of the hammer, during the movement of the piston to stress the springs 6, is prevented by a latch 7 engaging the hammer head, the release of the latch, to actuate the hammer, being effected at the end of the stroke by a crosshead 11. Admission of fluid pressure to the opposite end of the cylinder restores the parts to normal position. In a modification shown in Fig. 5 the hammer 3 is actuated through a lever 25 to which the piston 9 is connected through the cross-head 10. The lever 25 carries a latch 7 engaging the hammer-head the release of which is effected by a projection 26 on the cylinder 8. In another modification the springs 6 may be replaced by a body of compressible fluid as shown in Fig. 6, wherein the fluid 6a is contained in a cylinder 20 connected to the cross-head 10. In another modification Fig. 7, the hammer is mounted for rectilinear movement the latch 7 being released by a tappet on the rod 23 co-operating with the cross-head 11.

Addition to 308,737, [Class 69 (ii), Hydraulic presses &c.]. [Class 69 (ii).] Apparatus of the parent Specification is provided with a valve controlling the exhaust of liquid from a servomotorcylinder, said valve being controlled by a mechanical device which allows it to close when the driven member reaches the desired position. In apparatus for operating electric motor controllers, comprising a reservoir 2, Fig. 1, for liquid under pressure, a reservoir 4 for exhaust liquid, and connected pistons 3a, 3/, in cylinders 3g, 3h, a control lever 7 through contacts a' .. d<t>, 10a .. 10d, 10y completes a circuit including an electromagnet 2k for actuating valves 2a, 4a. On the shaft of the operated member is a cam 13 and an arm 10<1>, with a lost-motion connection with an arm 10<11>, the arm 10<11> co-operating with the contacts 10a .. 10d, 10y, and the arm 10<1> with contacts 10a<1> .. 10d<1>, 10x. As the shaft moves, the arm 10<1> completes the circuit of an electromagnet 12a, which tends to close a valve 12 ; when the shaft reaches the position determined by the position of the lever 7, a finger 13b drops into a notch 13a of the cam 13, so that the valve 12 is allowed to close and holds the parts. In order to allow a gradual closure of the valve 12, the corners of the notches 13a may be rounded. A relay 11 closes a switch 11a when the current passing through the motors exceeds a predetermined value, and completes the circuit of the electromagnets 2k, 12a. The Specification as open to inspection under Sect. 91 (3) (a) comprises apparatus for operating vehicle doors having a valve 15a, Fig. 2 (cancelled), for controlling communication between a cylinder 3g, a reservoir 2 for liquid under pressure, and a reservoir 4 for exhaust liquid ; a valve 12 is closed by its spring when allowed by a cam 13 on a driven shaft, the movement being completed after the closure of the valve 12 by the expansion of air in a reservoir 16, such air having been compressed by the pressure liquid during the first stage of the movement. In the event of obstruction to movement, the increased pressure in the cylinder 3g acts through a diaphragm 17a to close a valve 15b and shut off the supply of pressure liquid. This subjectmatter does not appear in the Specification as accepted.

Title: Method of stretching polymeric film
IPC: B29C55/06
Filed: 1970-07-07
Abstract: 1319320 Stretching polyester films E I DU PONT DE NEMOURS & CO 7 July 1970 [23 July 1969] 32912/70 Heading B5B A polyester film is continuously oriented by a method comprising longitudinally stretching a substantially amorphous polyester film at a temperature at least 10‹ C. above the glass transition temperature of the polyester, and at a rate of at least 50,000% per minute, over a shortened stretching span between, and defined by, an indirect heating means and a fast set of nip rolls. Preferably the distance between the heating means and the fast set of nip rolls, and the temperature of the film are such that subsequent stretching does not cause substantial increase in the variations of the thickness of the film over those existing before stretching but will facilitate the stretching of the film. Polyethylene terephthalate is the preferred polyester and the stretching temperatue may be from 90‹ to 160‹ C., especially 100‹ to 160‹ C., the film being stretched at a rate of less than 2,000,000% per minute, expecially between 100,000 and 1,000,000% per minute. In a preferred method the film is moved from a source of supply through a first set of nip rolls which is spaced apart and driven at a slower speed than the fast set of nip rolls, the indirect heating means is located between the two sets of nip rolls, and the length of the shortened stretching span is less than the sum of the radii of one roll from each of the sets of nip rolls; suitably less than three inches. Fig. 3 shows the result of an experiment on polyethylene terephthalate, in which the increase is disuniformity of the film caused by stretching is plotted against the stretching temperature at different separations of the heater and fast running nip rolls. The conditions selected are those where the magnification of the disuniformity is least.
