Abstract: 723,396. Adhesive tape; hand punches. KOENIG, C. Nov. 6, 1952 [Nov. 10, 1951], No. 27984/52. Classes 31 (2) and 140. [Also in Group XV] A tacky pressure-sensitive adhesive tape comprises a base tape consisting of a synthetic resinous material foil, having shallow indentations therein to prevent continuous surface contact between adjacent layers of the tape when it is rolled up, and two individual strip coatings of adhesive 5, 6, extending longitudinally of the base tape 1 with uncoated strips 1a, 1b, 1c between and on each edge of the tape. The basetape may be a polymer or copolymer of vinyl chloride, preferably without plasticizer, or regenerated celluloses of maximum thickness 0.05 mm., and the indentations may be in the form of points, or crossing or parallel lines. The adhesive may be usual natural rubber base adhesive. In the tab puncher shown in Figs. 11, 12, the adhesive tape 8 from a roll 7 is led between a feed roll 16 having serrated portions 16c, 16d and a counter roll 17 having serrated portions 17a, 17b which contact the uncoated central portion of the tape. Lever 23 is coupled to feed roll 16 to cause rotation thereof, and is connected to eccentric disc 21, which contacts spring 19, and brings counter roll 17, mounted on a shaft held by the spring 19, and roll 16 into intermittent engagement with the adhesive tape 8. Paper sheet 9 is placed on table 18 against stops 18a, and depression of handle 27 depresses lever 23 with consequent feeding of the required length of tape 8a, which is pressed on to the paper 9 by a compressible rubber ring 25. Each punch 22 mounted within a rubber ring 25 punches a hole through the tape and the paper as the ring is compressed, and a knife 26 cuts off the tape. The paper 9 is thus provided with a row of holes 9a, 9b, Fig. 10, each reinforced by tape strips 10, 11. The use of the tape is stated to prevent accumulation of adhesive on the rolls 16, 17, disc 13 and guiding flanges.

Abstract: 1,005,621. Spray-producers for coating recessed articles. K. M. OESTERLE. July 16, 1963 [July 17, 1962], No. 28171/63. Heading B2F. Spraying apparatus 22, Fig. 10, particularly suitable for coating articles 23 having a large recess with a liqud material such as lacquer, comprises a spraying jet, means for generating an electrostatic field between the apparatus and the article to be coated, and at least one rotatable spray member provided with a receiving surface which defines at its centre an opening on the longitudinal axis of the apparatus and which receives the lacquer from the jet and is formed with a spray edge, means being provided for varying the ratio between the amount of lacquer impinging on the surface and sprayed from the said edge and the amount passing through the opening. In the embodiment of Fig. 1, lacquer is sprayed from a nozzle 2 and part of it passes through a central aperture 4 around a guide cone 5 in a disc 3. The disc 3 is provided wtih openings 7 and together with a cone 6 is rotatably mounted on the supply tube 1 of the nozzle 2. The lacquer collected by the inner receiving surface of the disc 3 passes under centrifugal force through the openings 7 and is driven over a layer 8 of electrically conducting material and away from a spraying edge 9. An electrostatic field is generated between the layer 8 and the article. The ratio of material passing through the opening 4 to that passing through the openings 7 may be altered by axially adjusting the position of the cone 6 and the disc 3 on the tube 1. In the embodiment of Fig. 2 (not shown), the cone and the plate 3 are fixed and a diaphragm having a hole therein is adjustable between the nozzle and the opening 4, and in Fig. 4 (not shown), the cone 6 and plate 3 are rotatable and axially adjustable and the supply tube is parallel to a shaft which supports the cone and the plate. Fig. 5 depicts a similar apparatus in whch lacquer from the receiving surface is sprayed from the edges 9a of blades 14 produced by incisions in the disc 3. The lacquer reaches the blades through openings 7a in the cone 6 and the blades 14 also provide an air draught. The blades may be provided with pointed teeth, Figs. 6, 6a (not shown). A greater volume of liquid may be sprayed using three interconnected discs 4a, 4b and 4c, Fig. 9, which are rotatable and have three different diameters and central openings which also differ in diameter. The amount of coating material supplied to the spray edge may be varied by adjusting the angle of the spray emerging from the nozzle.

IPC: B05B3/16
Filed: 1957-09-10
Abstract: 812,863. Rotary sprayers. BUCKNER MANUFACTURING CO. Inc. Sept. 10, 1957, No. 28547/57. Class 69 (3). A stationary base 1, for mounting on a water supply fitting, carries a rotary sprinkler head 3 with a nozzle outlet opening 5 from which a water stream strikes either one of two opposed deflector surfaces 14, 15 of an impulse element S, so that, depending on which surface is struck the head will be rotated in one direction or the other. The element S, of generally rectangular shape, is pivotally mounted on horizontal trunnions 11 extending from a boss 10 of a sleeve 9 rotatably mounted on a spindle 8 projecting from the sprinkler head. Lateral swinging of the element about the spindle is limited by a finger 17 depending from the boss and projecting between lugs 18, 18a on the head, and the lug spacing is sufficient only to allow the displacement of the element to bring either one deflector surface or the other into line with the water stream. The element includes a weighted part 13, and a cross-bar 16 which normally bears against an arm 6 projecting from the head. When the stream strikes a deflector surface the element and head are rotated, and in addition, the forward end of the element is depressed and when the element swings back under the influence of the weight 13 its crossbar 16 strikes the arm 6. When the stream is uninterrupted by a deflector surface it strikes an adjustable pin 7 on the arm 6 and is broken up. The finger 17 is held against one lug 18 or the other by a snap-action spring 28 engaging the finger 17 and a finger 27 of a ring member 20 straddling the spinkler head. A spindle 21 of the ring member is pivotally mounted in a boss 19 of the head, and a pin 24 is pivotally mounted in a fork 23 of the ring. When the pin 24 is vertical it moves between stationary stops 25, 26 on the base 1 and when the pin strikes a stop the impulse element is turned relative to the head about the spindle 8 to bring the other deflector surface into line with the water stream with the consequent reversal of head rotation. The pin 24 may be swung clear of the stops to allow a continuous rotation.
