Title: Panel Light Modules
IPC: G08G5/06
Filed: 1967-05-15
Abstract: 1,199,602. Lamps. E. W. BLISS CO. 15 May, 1967 [19 May, 1966], No. 22449/67. Heading F4R. A panel light module comprises one or more light bulbs embedded in polyester resin contained in a sleeve which transmits light through one of its ends. The polyester serves as a lens and as a support for the bulb, and is preferably dyed to act as a light filter. In Fig. 4A an aluminium sleeve 322 contains two bulbs 318 each in a separate compartment separated by an opaque divider 324. The polyester 320 and 326 is dyed yellow and the upper surface 330 of the module is roughened to produce a diffusing effect. The inner walls of the sleeve act as a reflector and heat sink. Each section of the upper surface 330 is masked to provide two arrow-heads which will appear yellow when the appropriate bulb is energized (Fig. 4B, not shown). In a modification (Figs. 5A, 5B, not shown) one compartment has two bulbs and the mask is rectangular; green polyester is used. In another form (Figs. 6A, 6B, not shown) the divider 324 does not extend for the whole length of the sleeve and the portion of the latter above the divider is filled with clear diffusing polyester. In this case the top of the sleeve is not masked so that a circular illuminated area is seen. The compartments are filled with red and yellow polyester respectively. The modules may be used as repeater lamps in the display panel of the airfield control system of Specification 1,199,603, (Figs. 1, 2, not shown). The light modules are covered by a translucent sheet 302 (Fig. 4A) which transmits about 70% of the light. An opaque top sheet 300 is cut away in the portions of the panel where the lights occur (Fig. 1, not shown).

Title: Method and apparatus for testing pressure within sealed con tainers
IPC: G01M3/24
Filed: 1973-05-10
Abstract: 1429866 Testing fluid pressure CPC (UNITED KINGDOM) Ltd 10 May 1974 [10 May 1973] 22455/73 Heading H4D The pressure within a sealed container having a flexible metal wall is tested by electromagnetically exciting wall vibrations first by one excitation frequency and then by another, sensing sound from the wall with a microphone, and producing a respective output signal when the sound amplitude arising from either excitation exceeds a threshold level. Fig. 3 shows one of six testing stations spaced in the direction of travel of a conveyer 2 on which are packs 3 of metal-capped jars to be tested for their degree of vacuum. Three columns of jars are tested by the stations operating in respective pairs; the first, third and fifth station using one test frequency and the other stations using the second frequency. The two frequencies are selected to give wall resonances under zero and poor vacuum conditions respectively. At the station shown, cap vibrations are induced by a CW square-wave energized electromagnet 29 and sensed by microphone 33. A tube 32 and/or electrical filter discriminate against spurious noise. If the threshold amplitude is exceeded, a marker 34 inks the pack and pushes it to one side of the conveyer for rejection; an alarm (light or horn) is also actuated. Mechanism 17, 18, 19, 21, 26, 27 enables the height of the electromagnet and microphone to be adjusted to suit different jar heights. Three or more excitation frequencies may be used to cover the range of natural vibration frequencies over which jars are to be rejected. The housing of each test station is acoustically lagged to avoid housing resonances.

Title: Improvements in centrifugal clutches
IPC: F16D13/76
Filed: 1950-09-14
Abstract: 674,600. Centrifugal clutches. KREIS, F., and S.I.B.A. SOC. ITALIANA BREVETTI AUTOMOBILISTIC AR.L. Sept. 14, 1950 [June 20, 1950], No. 22621/50. Class 80 (ii). A centrifugal clutch contains two members which, when rotated relatively to each other, increase a spring force acting on a pressure plate of the driving clutch part and tending to disengage the frictionally engaging plates. The relative rotation of the two members takes place only when the clutch is under load, so that the engagement and disengagement of the clutch plates, produced by the movement of' weights under the influence of centrifugal force, occurs at a higher rotational speed than when it runs free. The clutch is particularly intended for use as the starting clutch of a heavy vehicle. A driving shaft 1 carries a drum 2 on which are fixed clutch plates 4 engaging driven clutch plates 12 on a .further drum 14. The drum 14 is mounted for limited, rotation on a drum 16, fixed to the driven shaft 15, containing a plate 17. In the Figure, the plate 17 is urged to the left by springs 23, 24, while it is constrained for rotation with the driven drum 16 by grooves 18. Inclined faces 17<SP>1</SP> on the plate 17 co-operate with inclined faces 19 on a ring 20., which is seated on bolts 21 guided in the frontal face of the drum 16. The bolts 21 abut a thrust bearing 22 separating the driven part of the' clutch from a pressure plate 11 in the driving clutch. part. Axial thrust from the springs 23, 24 is transmitted through the plate and rings 17, 20, bolts 21 and thrust bearirig 22. to the pressure plate 11 which is thereby urged so that the friction discs 4, 12 are disengaged. Weights 5 in the driving drum 2 and weights 27 on the driven drum 14 are urged inwards by springs 6, 28 but move outwards. under centrifugal force to engage the friction discs 4, 12, the engagement produced by the movement of the weights 5 preceding that by the weights 27. If the clutch is rotated initially with the driven shaft under load, the drum 14 rotates relative to the drum 16 fixed to the driven shaft and the interaction between the inclined faces 17', 19 increases the compression of the springs 23, 24. Complete engagement of the discs 4, 12 is thus not possible until the weights 5 are rotated at a higher speed than would produce engagement if the clutch, were running free. The weights 27 allow the clutch to be engaged on rotation of the driven shaft 15 if the driving shaft 1 is'stationary, so that a vehicle in which the clutch is mounted can be started by towing.

Addition to 377,723. [Class 99 (ii).] The piston a of the cleaner described in the parent Specification is slidably mounted on a sleeve f which is itself slidable on a spindle h connected to the restraining cord b, and the spindle carries at its outer end a basket of scraper springs k secured between two collars l, l<1>, the former being slidably mounted on the sleeve f and the latter fixed to the said spindle. A compression spring g is disposed between the piston a and the collar l, and a counter compression spring i may be disposed between a stop or flange f<1> at the outer end of the sleeve f and a collar m on the spindle h. In operation, the pressure of the driving-fluid on the piston causes the latter to slide and with it the sleeve f and collar l, thus increasing the diameter of the scraping- basket and forcing the springs k thereof against the inside of the tube being cleaned ; upon removal of the pressure during the return stroke of the piston the basket restores itself to its original size.

Abstract: 243,318. Bornmann, C. Nov. 20, 1924, [Convention date]. Indicators, electric. - In apparatus for indicating the level of liquids more particularly in liquid manometers of flow meters the capacity of a condenser is varied in accordance with the level. An apparatus adapted for measuring the level of liquid in a tank a, Fig. 1, comprises a metal tube c provided with a dielectric coating d. The tube c is connected in series with a high resistance indicator A and an alternator. The capacity, and consequently the indication, is varied in accordance with the height of the liquid. Fig. 2 shows an apparatus for indicating the flow of fluid. Pipes p at each side of a restriction o in the fluid pipe are connected to chambers h, j containing mercury m. A cylinder having a metal coating k covered by insulating material is contained in the chamber j and is surrounded by insulating liquid n. Differences of pressure, dependent upon the fluid flow, vary the height of mercury in the chamber j and hence the capacity of the condenser formed by the coating k and the mercury. The coating k is of helical form so as to provide for uniform calibration of the measuring instrument Z and indicator A. In a modification the liquid forms a variable dielectric of the condenser. Further a dielectric in the form of a float may be used.
