Title: Improvements in or relating to time-fuze devices, particularly for marine uses, e.g.for smoke-signal and smoke-screen buoys
IPC: F42C9/04
Filed: 1939-07-06
Abstract: 591,050. Smoke buoys etc.; fuzes. BRITISH ELECTRIC METERS, Ltd., COOP, N. B., and BROWN, R. T. July 6, 1939, No. 19729. [Classes 9 (i) and 9 (ii)] A clockwork time-fuze device for marine use, as in smoke-signal and smoke-screen buoys, comprises clockwork, time-delay, setting, and tripping mechanisms all enclosed in a watertight container, the setting mechanism being capable of being set by means external to the container. Means are also comprised whereby a short trial run of the timing mechanism may be performed without the tripping mechanism being released. The fuze device is shown as applied to a smokeproducing buoy. A trigger h holds a percussion cap c away from a fixed striking pin g against the action of a spring f. Through the cover-plate i of the water-tight container b passes a spindle j on the outer end of which are fixed a dial-plate m and radial arm k. The plate m is surrounded by a fixed annulus n formed with notches o with which a pin q on a, freely movable pointer arm p co-operates, to position the arm relative to the graduated dialplate m. Beneath the cover i the spindle j carries a toothed wheel s with a longitudinally extending annulus t and a stop pin u. A notch v formed in the annulus is closed by a circular shield w except when the device is set for a time above a predetermined minimum. Loosely mounted on the inner end of spindle j is a collar 2 having a radial pin 3 with a roller riding on the edge of the annulus t. A pin 5 and slot 6 couple the collar to a clock mechanism comprising a toothed wheel 7, spring 12 and escapement mechanism embodying a balance wheel 14. Engaging the collar 2 is a pin 15 at one end of a lever 16 which also carries a pin 17 bearing against one end of the trigger h. The toothed wheels s and 7 are geared together by means of a lay shaft 8 and pinions 9, 10 so that a manual rotation of the arm k serves to wind the spring 12. On removing a locking pin 24, the arm k may be moved within the limit allowed by a slot 20 and pin 21 without the shield uncovering the slot v and the mechanism can be watched through a window 31 for a preliminary test. To set the apparatus, the pointer arm is moved to the required reading on the plate m, the pin 21 removed and the arm k moved round until arrested by the pointer. This winds the spring and the mechanism runs until the pin 3 reaches and enters the slot v. This allows a longitudinal movement of the sleeve 2 which releases the trigger h.

Title: Improvements in or relating to ultrasonic systems
Inventor: MOE LOWELL ADRIAN
IPC: G10K5/02
Filed: 1964-05-12
Abstract: 1,061,531. Ultrasonic resonators. PEAVEY CO. May 12, 1964, No: 19755/64. Heading G5J. Collapse of oscillations in an ultrasonic resonator which may be open, as shown, or closed, as in Fig. 2 (not shown), is prevented by a baffle 21 having a flat surface 25 co-planar with the oblique section 17 of opening 16 to direct incoming fluid into the space between the baffle and the opening. In the closed resonator, the baffle is pivoted to permit circulation of the fluid. The resonators produce non-sinusoidal waves of frequency 15,000 to 100,000 cycles per second and are used to disperse rodents and other pests. To prevent the pests acquiring a deafness immunity to a particular wavelength, fluid at constant pressure is supplied to more than one resonator of different lengths, thereby producing modulating overtones. The same result is achieved by supplying fluid at different pressures to identical resonators. Alternatively, the fluid may be supplied through a variable pressure valve to a single resonator.

Title: Vehicle load-distande indicating device
IPC: G01G19/414
Filed: 1973-04-26
Abstract: 1452905 Measuring vehicle load PEAK COMPONENTS Ltd 16 April 1974 [26 April 1973] 19813/73 Heading G1N A load-distance measuring device includes a start pulse generator I which emits a pulse at the end of each mile travelled by a vehicle, the pulse triggering a constant frequency oscillator from which pulses are gated at 7 into a metering device 8, and are also fed to a counter 3 which connects to a D-A converter 4. The analogue signal representing the pulse count is compared in comparator 5 with the signal from the load weighing device 6 and at equality an inhibit signal is fed to the gate 7. Thus the number of pulses passed to the metering device represents the vehicle load at the end of each unit distance. Alternatively the total tonmileage may be printed-out. In an alternative embodiment Fig. 2 (not shown) the load measuring device provides a digital signal and when the number of pulses from the counter or directly from the oscillator, equals the output of the load measuring device the comparator sends an inhibit signal as before.

Title: Improvements in or relating to the production of artificial filaments and similar products from cellulose xanthogenates
Inventor: DRISCH NICOLAS
IPC: D01F2/22
Filed: 1950-08-11
Abstract: Filaments and similar products are obtained by extruding through a spinneret into air at room temperature a dispersion of cellulose xanthate in aqueous caustic soda solution, this dispersion having a viscosity of at least 1,000 poises, a cellulose content of at least 6 per cent, and a caustic soda content of 3-10 per cent., and the cellulose xanthate products are stretched continuously with their production and thereafter submitted to treatment to regenerate the cellulose.  The cellulose xanthate dispersion (xanthogel) may be obtained by treating viscose with an organic solvent, e.g. acetone or pyridine, which is miscible with water but which does not dissolve cellulose xanthate, whereby a separation into two layers is effected, one layer containing the solvent diluted with water and the other containing viscose of low water content.  The cellulose xanthate gel may also be obtained by xanthating cellulose with more than 35 per cent. of carbon disulphide in the presence of caustic soda, in such quantity that the final product will contain 3-10 per cent. of caustic soda, malaxating the xanthate so obtained under high pressure at a temperature below 10 DEG C. and adding during the malaxation such quantities of water as are necessary to achieve a viscosity of at least 1000 poises with a cellulose content of at least 6 per cent. The stretched filaments may be fixed and purified by treatment with cold dilute acid or with a hot aqueous liquid, e.g. water at 80-90 DEG C., or with a hot saline solution. Additional stretching may be effected during the fixing treatment. Specification 709,700 is referred to.

Title: Control device for hydraulic motors applicable to the operation of aircraft control surfaces
IPC: F15B13/04
Filed: 1951-08-29
Abstract: 730,559. Fluid-pressure servomotor-control systems. NORTHROP AIRCRAFT, Inc. Aug. 29, 1951 [May 28, 1951], No. 20414/51. Class 135. In a hydraulic servomotor control system having a piston movable in a cylinder under the control of a spool-type control valve which in its neutral position permits leakage flow to either side of the piston, a by-pass conduit having a restricted orifice connects opposite sides of the piston so that near the neutral position of the control valve a considerable reduction in piston velocity takes place. As shown in Fig. 2, a screw-threaded by-pass conduit 66 mounting at its centre a plug 67 having a restricted orifice 70 is disposed between outlet ports 32 of the housing 24 of a control valve 16 having a valve spool 35 slidable in a fixed sleeve 34 and ports 31 leading to opposite sides of the piston 29 of a doubleacting motor 11 operating an aircraft-control surface. The plug 67 is recessed at either end to receive the inner ends of cartridge-type filters 71 which are retained in position by retainers 75 having grooves spaced around the peripheries of their inner ends 74 to permit flow of liquid between the ports 32, 31. Groups of metering holes 36 associated with valve spool metering lands 44 are staggered lengthwise around the sleeve 34 so that in the neutral position of the spool the holes at either end of each group remain half uncovered to permit leakage flow of pressure liquid from a supply port 39 to one of the ports 32 via sleeve ports 37 and a recess 41 and from the other port 32 to an exhaust port 40 via radial and axial ports in the valve spool. The half holes 36 and the orifice 70 are of the same order as to area. On movement of the valve spool 35 from its neutral position some of the liquid flowing from the supply port 39 to the appropriate port 32 passes through the orifice 70 so reducing the amount of liquid which is effective in moving the piston. The proportion of the total flow passing through the orifice progressively reduces as the valve moves from its neutral position to its fully open position so that the reduction in piston velocity is a maximum at or near the neutral position of the valve. Hence for minute movements of the control stick by the pilot a slow-response of the control surface movement takes place. The cylinder of the motor 17 which is formed integral with or connected to the valve housing 24 is operatively connected to the aircraft control surface so that on movement of the control surface the fixed sleeve 34 follows up the movements of the valve spool 35.
