Title: Improvements in or relating to apparatus for applying a coating of fluent material to an object
IPC: B31B50/62
Filed: 1961-08-02
Abstract: 990,238. Coating apparatus. SUNKIST GROWERS Inc. Aug. 2, 1961 [May 11, 1961], No. 44988/64. Divided out of 990,237. Heading B2B. An applicator for applying a coating of fluent material to an object, comprises a rotatable element disposed in a chamber in a retainer, an interior wall of the chamber being engageable by the element to limit movement thereof inwardly of the chamber, sealing means circumscribing the chamber and being engageable by the element upon movement thereof outwardly of the chamber there being means for introducing the fluent material into the chamber. In the arrangement shown, an applicator 60 consists of a ball 65 located in a chamber 64 formed by a cylindrical wall 64a; a generally conical wall 64b and an asperical wall 64c against which ball 65 abuts when it is in its uppermost position shown in Fig. 4. A sealing ring 68 is incorporated and the ball 65 seals against this ring when in its lowermost position as indicated in Fig. 3. Fluent coating material is fed under pressure through passages 69 and 70 and the pressure keeps the ball seated against the sealing ring when the applicator is not in use. In operation the article to be coated, e.g. box flap B<SP>1</SP>, Fig. 4, passes between the applicator and a plate 34 so that the ball is lifted from the sealing ring 68 and into contact with the asperical wall 64c. The coating material then flows on to the flap B<SP>1</SP>. The applicator cap 66 is recessed so as to form a reservoir 66c and the relative positions of the applicator and the plate 34 are such as to give the required thickness of coating. Several such applicators can be provided in a single head having an inlet for coating material and internal passages leading to the separate applicators. In such an arrangement the applicators can be arranged to give strips of coating material in any desired pattern, applicators not required being blanked off by suitable plugs.

Title: An improved method of an apparatus for dust collection
IPC: B01D46/04
Filed: 1963-11-18
Abstract: 1,007,726. Gas filters. BELL INTERCONTINENTAL CORPORATION. Nov. 18, 1963 [Jan. 14, 1963], No. 45436/63. Heading BIT.  In a dust collector which includes a plurality of fabric filter tubes 28 mounted vertically between a support 50 at the top and a cell plate 12 at the bottom, the latter being apertured to allow gas to be filtered and introduced through an inlet 20 to enter the filter tubes 28, a nozzle 54 is provided within a short distance from the upper end of each tube 28 for the introduction of a jet of air downwardly into the tube whereby an air bubble is formed, which as it travels down through the tube loosens the filter cake formed on the ingoing side of the filter fabric. The loosened filter cake falls down under gravity through a grating 24 into a hopper 22. Before the cleaning operation, the inflow of gas to be filtered is shut off and each filter tube 28 is then in a semicollapsed condition, the effect of the air jet being, as shown in Fig. 3, to cause the tubes to snap suddenly outwardly to a taut condition and back as the air bubble 58 passes. The air jet may be of a pressure between 40 and 150 p.s.i., preferably between 70 and 100 p.s.i., and last up to ¢ second. Preferably a number of jets are used, at intervals of between 1 and 20 seconds. The upper ends of the filter tubes 28 should preferably be open to permit a free flow of air to fill the vacua that would otherwise be created behind the air bubbles. In the absence of such free flow, this air is drawn in by reverse flow through the filter tubes. When it is desired to effect closure of the filter tubes during the filtering cycle only, flapper valves (Fig. 4, not shown) or other suitable valves may be fitted to the upper ends of the tubes.

Title: Flow control means for hydraulic systems
IPC: B62D5/06
Filed: 1972-10-04
Abstract: 1406090 Power steering systems TRW Inc 4 Oct 1972 [20 March 1972] 45769/72 Heading B7H An hydraulic power steering system comprises a single pump 10 in combination with a flow control valve 15 for supplying the output of the pump to both a primary hydraulic circuit 16 including a power steering actuator 18 and a secondary hydraulic circuit 17 such as an hydraulic cylinder 19 for an implement lift. The pump 10 has an output flow increasing substantially proportional to the pump speed, the valve 15 being integral therewith. The circuit 16 has a control valve 1 while circuit 17 has a control valve 2. Control valve 1 is partially closed to operate actuator 18, such that a port 27 leading to the circuit 16 will close and valve spool 45 moves to the left to maintain a desired flow to both the circuits 16 and 17. When the flow to circuit 16 diminishes a pressure drop occurs across an orifice 57 in the spool 45, such that a spring 61 urges the spool to the left to restrict the flow to the circuit 17. Thus, the more valve 1 is closed the more flow to circuit 17 is restricted, thus maintaining the desired flow split. The actuator 19 is operated by closing the valve 2, thus causing the spool 45 to restrict flow to the circuit 16. A pressure relief valve comprising a spool valve (82), Fig. 4 (not shown), and spring (92) is fitted in the outlet from the pump. The spool valve (82) houses a ball (96) pressed by a spring (98) adjustable by a threaded plug 99.

Filed: 1963-11-20
Abstract: 976,326. Removing bark. BELOIT CORPORATION. Nov. 20, 1963, No. 45838/63. Heading B5L. A ring-type debarker comprises a tool carrying arm 13 pivotally mounted intermediate its ends on a ring 10, a compression spring 36 having one end resting against an abutment 32 and its other end in contact with a crosshead 42, and flexible member 44 connected at one end to the crosshead and having its other end passing loosely around at least a portion of the outer end of the arm and secured to the arm, the surface of the outer end of the arm engaged by the flexible member being contoured so that the resultant force of the spring, urging the tool towards the centre of the ring remains substantially constant throughout the range of inner and outer movement of the tool carrying end of the arm. The ring 10 carries a plurality of the debarking arms, each arm being mounted by bearings 16 on a pin 19 having a portion 19a secured by a nut 26 to the ring 10, a spacer 24 serving to position the arm from the ring. Wear plates 28, which are normally out of contact with the arms, are provided to prevent excessive load occurring on the arms in the event of a log hitting the arms and tending to deflect the arms towards the ring. A tubular housing 31 is located adjacent each arm and houses a double coil spring 36 having one end engaging a closure member 32 serving as an abutment, and the other end secured by a nut 37 to a rod 39 which extends through a slot 34 in the closure member 32. A crosshead 42 is secured to the rod and the flexible member which is in the form of a cable 44 has its ends secured to the crosshead and passes over the outer end 13a of the arm 13 and is secured to the arm by a cleat 46, the spring acting to urge the arm into engagement with a stop 47. The contour of the outer end of the arm 13a is such that a tool 13b carried by the arm acts with a constant force on a log L to be debarked throughout the whole range of movement in the arm, the contour compensating for the centrifugal force acting on the arm during its range of movement, the difference in force exerted by the spring as a result of movement of the arm, and the difference in the effective leverage of the arm upon rotation about its pivot.

Abstract: 1457107 Colour television BRITISH BROADCASTING CORP 30 Dec 1974 [5 Oct 1973] 46705/73 Heading H4F A PAL or NTSC colour television signal in pulse form (e.g. in digital or sampled analogue form at input 30) which has been sampled at a frequency which bears a ratio of small integers to the subcarrier frequency (e.g. three times), is decoded by multiplying 32 the samples of the luminance Y and colour difference signals U and V by coefficients 34 appropriate to each of the Y, U and V signals and to each subcarrier phase position to thereby provide unfiltered output signals Y <SP>+</SP>, U <SP>+</SP> and V <SP>+</SP> which can be reversibly recoded (e.g. at 22, 24 and 26) to form the original input signal substantially without degradation. Considering a PAL signal sampled at three times the subcarrier frequency; the samples comprise P 0  = Y 0  + U 0 ; P 1  = V 1 -¢U 1 -#<SP>3</SP>/ 2 V 1 ; and P 2  = Y 2  - ¢U 2  + #<SP>3</SP>/ 2 V 2  and these are decoded so that Y<SP>+</SP>, U<SP>+</SP> and V<SP>+</SP> at each of the three phase positions are derived in multiplier 32 according to the following matrix The decoding may be used when a coded signal such as a prerecorded signal is mixed 20, or otherwise processed with a studio signal from a local source 10, this signal being filtered 14 and sampled at three times the colour subcarrier frequency in converter 18 before being mixed 20 with the decoded and normalized 36 prerecorded signal, the resulting composite signal then being PAL encoded 22-26. The prerecorded signal may be displayed on a monitor 42 after being decoded 32, 34, D-to-A converted 38 and filtered 40 with a relatively long time constant to average the instaneous outputs. Block decoding may be effected by operating on Y, U and V signals which each comprise the sum of the three successive samples thereof occurring during any subcarrier period. The resulting block samples which are arranged to occur sequentially at thrice subcarrier rate are converted by a register into parallel outputs which are decoded in a manner similar to the first embodiment, but in which only a 3 Î 3 matrix of coefficients is required, before being processed with a local signal (Fig. 2, not shown).
