Title: Spraying nozzles
IPC: B05B5/03
Filed: 1971-08-02
Abstract: 1316393 Spraying nozzles P G VICARD 2 Aug 1971 [16 Sept 970 17 May 1971] 36205/71 Heading B2F A spraying nozzle for producing a conical discharge comprises a body 2 with coaxial orifices 2c, 2e, Fig. 1, joined by a curved wall 2d, the angle α between the tangents at orifice 2c being greater than the angle # between the tangents at orifice 2e. As shown, spray material e.g. a liquid, enters a bore 2a, passes through an aperture 3e in a member 3 and is guided in a spiral path by a wall 3c, Fig. 2, to a chamber 26 and then passes through the orifices 2c, 2e. The member 3 may have a shoulder 3f to prevent foreign bodies falling into the orifice 2c. When the nozzle is used to spray solid particles in a liquid or gas, there may be provided a tangential inlet (2f), Fig. 4 (not shown), to the chamber 26. In a second embodiment, Fig. 5, 6 (not shown), the body 2 is in two parts screwed together and the spiral wall 3c is replaced by a helical rib (4e) on a hub (4) through which passes a tail (3g) of the element 3, which tail threadably engages a core (2g) spaced from an upper enlarged diameter portion of the bore 2a by radial arms (2h). In a third embodiment, Figs. 7, 8 (not shown), the body 2 is closed at its bottom by a circular plate (5) and liquid enters the chamber (2b) through a tangential inlet (2i). In a final embodiment, Fig. 9 (not shown), a double nozzle is formed by two nozzles each similar to that of Figs. 5, 6, the element 3 of one nozzle being widened at its top and threadably receives the body of the second nozzle. Any one of the nozzles may be disposed in a conduit to produce mixing with a fluid which flows through the conduit in a direction opposite to that of the nozzle discharge, Figs. 10, 11 (not shown).

Title: Improvements in devices for testing self propelled vehicles
IPC: G01M17/06
Filed: 1932-12-24
Abstract: 409,077. Testing wheel alignment of motor vehicles. HEENAN & FROUDE, Ltd., and WALKER, G. H., Worcester Engineering Works, Worcester. Dec. 24, 1932, No. 36552. [Class 106 (ii).] Apparatus for testing the wheel alignment of motor vehicles comprises means for supporting and rotating each of the wheels against brake resistance, means for counteracting the tendency which may exist for the wheels to creep sideways, and means for measuring the magnitude of such tendency. The vehicle is run on to fluted rollers 1, one for each wheel, which are driven from a suitable motor. It is held by clamps 4 or the like applied to the axle. As shown in Fig. 4, an adjustable stop 4<a> is arranged slightly to the rear of the front axle A. The stop comprises a roughened plate 5 engaging the axle and supported by a second plate 6 restrained from rearward movement by posts 7 which can rise and fall, but are prevented from moving backwardly by an adjustable drawbar 8. Rollers 9 allow one plate to move transversely relatively to the other. On the underside of the plate 6 is a pivot 10 for a lever 11 extending to the front over a scale 13 carried by the plate 6 and having a central zero. The pointer end 12 of the lever is held at zero by springs 14, but is also engaged by a projection 15 on the plate 5. When the brakes are applied and the rollers 1 rotated, if the brakes are equalized and no error exists in the disposition of the wheel tracks relatively to the king pins of the vehicle the pointer will remain at zero, otherwise the creep of the wheels sideways will be indicated by the pointer. In a modification, the clamp is of different construction and the pointer and scale are mounted on the drawbar, inclination of which due to side creep of the wheels deflects the pointer. Rails 22 serve to guide the vehicle to a central position in relation to the testing apparatus, such rails being adjustable to and from each other by a right and left hand screw 23 and gearing. To the same end idler rollers 25 carried by levers 26 on shafts 27 are operated by a linkage to be raised simultaneously, remaining symmetrically disposed to the vertical through the axis of the wheels to locate the latter vertically over the rollers 1. The power drum of Specification 387,371 may form one of the two idler rollers 25. The fluted rollers 1 underlying the front wheels are carried by a trolley 30 which after adjustment to the wheel base required, is locked to the underframe by a pivoted catch 30<a>. The trolley is held parallel with the rollers by two racks 32 engaging pinions 33 on a shaft 34, which also carries a wheel 35 engaging a pinion normally pressed out of engagement by which may be pressed in and turned by a handle to adjust the trolley. A locking catch 38 is also fitted. Specification 361,524 also is referred to.
Patent GB-780155-A (GB)
Title: Synchronising device for change speed gears
IPC: F16D23/06
Filed: 1955-12-21
Abstract: 780,155. Positive clutches. PORSCHE, F. Dec. 21, 1955 [Dec. 29, 1954], No. 36600/55. Class 80 (2). A synchronizing device for motor vehicle &c. change-speed gears, of the type in which the synchronizing means comprises a split spring ring, frictionally engageable by a tooothed clutch member and mounted on a supporting ring, is so formed that in one direction of rotation the servo assistance of the supporting ring assisting expansion of the split spring ring is rendered ineffective. As shown, a driven shaft 1 carries a member 4 on which an internally toothed clutch sleeve 5 can be slidden axially to engage with clutch teeth 10, 11 on hub members fast with pinions 2, 3 mounted for rotation about the shaft 1. Synchronizing split spring rings 15 are mounted on the hub members by supporting rings 17 having inwardly and outwardly extending projections 19, 18, engaging in slots 22 in each hub member and between the ends of the split ring 15, respectively. A small stud 23 in the hub member has a head 26 lying against the inner periphery of the supporting ring 17. When it is desired to' engage the sleeve 5 with the clutch teeth 10 from the neutral position shown, the vehicle being stationary and its engine idling, the main clutch is thrown out and movement of the gear lever initiated to engage lightly the teeth on the sleeve 5 with the outer friction surface of the split spring ring 15. Since the gears 2, 3, &c. will still be revolving at this moment, due to their inertia forces, this engagement tends to turn the split ring 15 in the direction of the arrow of Fig. 2 relative to the supporting hub 8, and by virtue of the projections 18, 19 the split ring then tends to turn the supporting ring 17 relatively to the hub member, so that it will take up an off-centre position with respect thereto and thereby wedge the split ring 15 apart into increased frictional engagement with the teeth on the sleeve 5. However, the head 26 of the stud 23 engaging the inner surface of the supporting ring 17 maintains the supporting ring substantially coaxial with its hub member, and thus prevents this servo assistance from becoming effective. The sleeve 5 can therefore readily be slidden over the split ring 15 to engage with the teeth 10 on synchronism. If the sleeve 5 is to be slidden axially out of engagement with the clutch teeth 11 and straight into engagement with the clutch teeth 10, the inertia forces to be overcome are substantially greater and the direction of relative rotation between the split ring 15 and the hub 8 is reversed, so that it is as shown in Fig. 3. In this direction of rotation, the stud 23 is ineffective and the supporting ring 17 wedges the split ring more firmly into engagement with the teeth on the sleeve 5, to give an increased synchronizing effect.

Abstract: 1398734 Component assemblies; strip line couplers TEKTRONIX Inc 15 Aug 1972 [23 Aug 1971] 37952/72 Headings H1R and H1W [Also in Division H3] A detector or temporary storage circuit comprises two transmission lines forming a directional coupler, the first being coupled to a capacitor which stores the combination of a signal fed to the first line and a pulse produced by a stepwave fed to the second. As shown, the sampling and detection of the wave applied at 14 is effected by the generation of a sampling pulse in coupler 24 so that the combined signal and pulse is stored in a capacitor 36. A similar coupler 26 and storage circuit is arranged to operate in opposite polarity so that when the outputs are combined the sampling pulses cancel. The sampling pulse is generated from a voltage step applied at 54 via an unbalanceto-balance converter to a charge storage diode 46 which steepens the edge. This step passes along the coupler and produces a pulse at 32 and 34 having a duration equal to twice the transmission time of the section L of the couplers. The positions of diode 32 and capacitor 36 may be interchanged and the coupler is so arranged that the sampling pulse does not reach the input terminal. A sampling detector is used in a phase discriminator to sample the output of an oscillator in response to a sampling pulse derived from a crystal controlled reference oscillator to provide a phase correction voltage (Fig. 8, not shown). Fig. 2 shows the construction of Fig. 1, the striplines being of gold above a gold ground plane. The diodes 32 and 34 are chips applied to conductor strip 108 and line 26 respectively. Capacitors 36 and 44 are connected to groundtabs 112, 114 extending round the edge from the ground plane. Resistors 42, 44 as well as line terminating resistors 28, 30, 60 and 62 are in deposited form.
