Title: Apparatus for spraying liquids
Inventor: MIXA WALTER
IPC: B05B1/04
Filed: 1962-09-27
Abstract: 1,004,905. Spray-producers. GASTURBINENBAU UND ENERGIEMASCHINEN ENTWICKLUNG PIRNA VEB. Sept. 27, 1962, No. 36649/62. Heading B2F. Apparatus for spraying liquids under pressure from aircraft comprises a cylindrical casing 4, Fig. 1, provided with orifices 6 and containing an axially movable piston 5 acted upon by the pressure of the liquid and is characterized in that the orifices 6 are slit-shaped, parallel to the axis of the casing, and that their effective outlet cross-section is varied when the piston 5 is moved through their co-operation with annular grooves 7 in the piston. The grooves communicate through ducts 8 with a longitudinal bore 9 in the piston. The axis of the casing is transverse to the aircraft and the orifices 6 face the direction of flight, the angle α, Fig. 3, between the plane of the orifices and the plane through the casing axis parallel to the direction of flight y being 75 degrees. The orifices are formed in segmental recesses in the cylinder wall, to reduce their discharge dimension and thus increase the efficiency of atomization. The liquid enters the bore 9 at X and its pressure moves the piston 5 against the force of a spring 12, uncovering a proportion of the area of the orifice 6 which is determined by the pre-adjusted position of a stop 13. The adjustment is made by rotating a component 15 which carries graduations. When the liquid supply is cut off the orifices are automatically closed by the return of the piston 5 due to the action of the spring 12.

The material is close to the vortical axis, yet outside the core of the vortex. Sliver 16 passes through the apparatus 10, seen in Fig. 1 to have a conical vertical section. Treating gas enters via the port 14 and exits via opening 15. The apparatus has a spiral cross section and this together with the conical longitudinal section, generates a vortical flow screen 20 is so shaped that the opening 20b in it corresponds to the core of the vortex where the gas is moving vertically. The sliver 16 passes through 20b at its periphery. The process is useful for aircooling freshly-spun threads.

Title: Improvements in or relating to dispensing valves
Inventor: SARETZKY HORST
IPC: F16N27/00
Filed: 1970-07-30
Abstract: 1,273,666. Dispensing valves. DE LIMON FLUHME & CO. 30 July, 1970, No. 36889/70. Heading B8N. A dispensing valve 10, e.g. for lubricant, comprises a generally cylindrical housing 11, a non- return inlet valve 13, an outlet opening 32, a sleeve 14 defining with the housing 11 a communication chamber 24, a piston 19 slidable within the sleeve 14 and defining with the sleeve 14 a reservoir 31, and resilient means 20 biasing the piston 19 towards maximum reservoir size. Admission of liquid under pressure through the inlet valve 13 acts on the piston 19 to discharge the reservoir 31 through the outlet 32, while liquid flows through the chamber 24 to the reservoir 31 on releasing the pressure. On applying an inlet pressure to the valve 10, the valve member 13 is raised, and a lipped sealing ring 21 is urged into engagement with a base portion 15 of the sleeve 14, a spring-urged ball 34 being raised from its seating to allow inlet fluid to pass through a base aperture 16 and act on the piston 19 to discharge the contents of the reservoir 31. On releasing the pressure, the valve 13 returns to closed position, the ring 21 becoming inoperative, and the spring 20 acts to return the piston 19, the fluid below it flowing through recesses 23, the chamber 24, recesses 27 and a slot 26 in a tubular member 25 to refill the reservoir 31. A range of members 25 of different length allows adjustment of the reservoir capacity.

Title: Improvements in the testing of the insulation of electric conductors
Inventor: MEADOWS STANLEY GEORGE
IPC: G01R31/02
Filed: 1952-05-23
Abstract: 753,557. Testing insulation resistances. SOUTHERN UNITED TELEPHONE CABLES Ltd. May 26, 1953 [May 23, 1952], No. 36972/54. Divided out of 737,746. Class 37. Apparatus for testing the insulation of an insulated conductor by applying a known test voltage to the conductor through a resistor of known value, comprises timing means to determine the initial charging period of the conductor and to operate, at the end of that period, switching means for transferring the circuit from the conductor to the test voltage through a second resistor of equal valve to the first resistor and for completing a circuit to an output signal terminal, and means responsive to the potential relative to earth at the junction of the second resistor and conductor to prevent the completion of the circuit to the output signal terminal when that potential is below a predetermined valve. In the Figure conductor 1 receives the test voltage firstly via resistors R1, R2 and secondly through a single resistor R3 equal to R1+R2 and voltage drawn from the R3/wire 1 insulation resistance junction is applied to the grid of electrometer valve V2 and the V2 output goes into diode V4 through amplifier V3 and if the voltage across R3 is high enough due to the insulation on conductor 1 being below the standard required V4 conducts and triggers dual state valve V5 so that its second anode 15 conducts and operates EX. When the test voltage charges conductor 1 via R1, R2 a multi-vibrator V1 is actuated so that relay AX operates and locks followed by slugged relay BX whose delay period determines the period of charging the. conductor 1 since BX operates quick-acting relay CX which is effective in transferring conductor 1 into connection with R3. The actuation of BX also energizes a slugged relay DX to release BX and CX and if EX has not operated then when DX falls back an output voltage 7 is available and used to operate a relay (not shown) which connects the next conductor to be tested. If EX has operated no output signal is available and the process stops and fault lamp 16 lights up. The operator releases EX by closing RS. The slugged relay BX may be replaced by a known form of electronic timer. The relay arrangement described in Specification 753,471, [Group XIX], may be used for connecting in several insulated conductors to the test circuit in sequence.
