Title: Improvements in lawn sprinkler hose
IPC: B05B1/20
Filed: 1954-11-29
Abstract: 751,097. Flexible hoses; hose couplings; stopping pipes. UNITED STATES RUBBER CO. Nov. 29, 1954 [May 25, 1954], No. 34483/54. Classes 99(1) and 99(2). [Also in Group XXIX] The hose, which is :of plasticized polyvinyl chloride, has a flat base 5, an arcuate perforated top wall 6 and an integral longitudinally extending partitioning wall structure 12, 13 and 14 which divides the hose into separate passages 15-18. Longitudinal slits 8-10 are spaced along the outer wall of the passage 17 and similar perforations 7 and 11 are arranged in the outer walls of the passages 15 and 16 respectively. The passage 18 acts as a booster passage since water flows therethrough from the inlet end to the outlet end before being fed to the outlet passages. Male and female couplings 4 and 3 are secured at opposite ends of the hose, and the female coupling comprises a tubular shank 19 and a ferrule 26 between which the extended end of the hose is sandwiched, and a threaded nut 23 rotatably attached to the shank. The male coupling is similar but with an external thread formed on the outer end of the shank for engagement with a nut such as 23, so that a number of hose lengths may be coupled together. A cap 31 closes the tail end of the hose.

Abstract: 992,628. Feeding webs. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Oct. 12, 1961 [Oct. 12, 1960], No. 34929/60. Heading B6B. Apparatus for accumulating continuous, moving, web material comprises two sets of bearing surfaces, one of which sets is movable relative to the other, and which sets are so arranged that continuous web may be passed along a continuous path around the bearing surfaces forming two, interleaved, spiral form portions. Fig. 2 (not shown) illustrates a fluid bearing surface as described in Specification 970,871. Fig. 1 shows two sets of such fluid bearing surfaces, 1, 2, 3 . . . and 1a, 2a, 3a . . . , respectively, the bottom set of which is free to move, under gravity, towards and away from the upper set. The continuous web material is passed around the bearing surfaces, as shown in broken lines, along a path constituted by two interleaved, coplanar, spiral - form portions joined at the centre point of the path portion between surfaces 1 and 1a. The semi-circular fluid bearing surface can be replaced by a number of freely rotating rollers, as shown in Fig. 3. The two sets of bearing surface means can also take the form of freely rotating rollers, as shown in Fig. 4. Instead of rollers, in Fig. 4, quadrant-section fluid bearing surfaces may be employed. Guides may be employed to aleviate lateral movement of the web when moving through the apparatus.

Title: Improvements in draughting machines
IPC: B43L13/08
Filed: 1947-12-31
Abstract: 652,166. Draughting-machines. CELLOPHANE SOC. ANON. Dec. 31, 1947, No. 34987. Convention date, June 6, 1945. [Class 97 (iii)] The drawing head for a draughting-machine is provided with a braking device for retaining the rules in any angular position and a locking device for holding the rules in one of a series of predetermined angular positions, both devices being operated solely by a common manual means such that when either device is operative the other is inoperative. The manual means comprises a control knob 3 mounted so as to rotate about a vertical axis on a cylindrical column 4 integral with the system of rules 2, whereby rotation of the knob in one direction locks the locking plunger 9 in recesses 13 on the support 1 and unlocks the brake or clamp 6 and rotation in the other direction releases the plunger 9 and then applies the brake 6. The plunger 9 is disposed in a core coaxial with the column 4 so as to slide freely without rotation therein and bears a stud 10 co-operating with a ramp 11 having a horizontal portion 14 formed in the inner part of the knob 3. The knob 3 is held in a fixed vertical position by screws 15 and has a screw-thread 8 co-operating with a coaxial nut 7 in which the brake-rod 5 of the brake 6 is supported. Rotation of the knob 3 from the position shown causes the stud 10 to ride on the ramp 11, thus raising the plunger 9 from the recess 13 until it is free of the support member 1 in which position the stud 10 is on the horizontal portion 14 of the ramp 11 and at the same time the brake-rod 5 is lifted by means of the screw engagement of the nut 7 with the knob 3. In this intermediate position the rules may be rotated freely with respect to the support and may subsequently be clamped in any intermediate position of the rules by further rotation of the knob 3 which brings the brake 6 into engagement with the support 1. Rotation in the reverse direction releases the brake and then lowers the plunger 9 into the conical recess 13 under the influence of the spring 12. In a modification, the brake rod is coaxial with and mounted in a bore in the locking plunger 9 and may be provided at its upper part with a stop co-operating with a corresponding supporting surface of the locking plunger so that the brake rod is raised by the plunger 9 as its stop 10 follows the ramp 11. In a further modification, the brake rod is coaxial with and slides in a bore in the cylindrical column 4 and the plunger 9 is mounted externally of the column and knob. In this modification the brake rod is threaded to engage a nut fixed to the knob so that rotation of the knob raises the brake-rod and the ramp 11 is located externally on the knob 3, the stud 10 being guided through the intermediary of a pivoted lever whose free end engages the ramp. Specification 652,167 is referred to.
