[Classes 20(ii) and 20(iv)] Foundations, underground basements, cellars, tanks &c. which are waterproofed by the application of bitumen-loaded sheeting in two or more layers have joints formed between the main waterproofing layers at corners between structural surfaces, by means of strips of bitumen-loaded hessian along the edges of the main waterproof layers, the strips being bent to conform with the angle at the joint and overlapping each other on the main waterproofing layers and being welded in position by the application of heat. A foundation may be formed by a ground slab 2, Fig. 1, of concrete, to which two or more layers 3, 4 of bitumen-loaded hessian sheeting are applied and welded to each other and to the slab by surface heating. Where the wall 1 meets the foundation, joints are established between the main vertical layers 3, 4 and the horizontal main layers 3, 4 projecting beyond the wall, by bending the lower edges of the inner and outer vertical layers outwardly to form overlapping flanges 6, 5 which are then welded by heating to each other and to the horizontal main layer 4. Adjacent layers break joint with each other, horizontally and vertically. A protective coating 14 of cement is applied and a skin wall 15 may be erected for the protection of the main waterproofing of the structure. If the ground cavity is insufficient to permit working exteriorly of the main walls, a skin wall is first built, waterproofing layers applied interiorly thereof and the main walls then erected in close juxtaposition to the waterproofing. Applications to form corner joints where the main waterproofing layers are (a) bitumenloaded felt fibre sheeting or (b) bitumenloaded hessian sheeting are described.

Filed: 1925-09-18
Abstract: 262,539. Know Mill Printing Co., Ltd., and Mort, T. L. Sept. 18, 1925. Testing and measuring viscosity of liquids. - Comprises a method of determining or comparing viscosities consisting in using to indicate viscosity measurement of the thickness of liquid between two definite surfaces required to enable their adhesion to be overcome by a. definite force in a definite time. The hollow stem a is formed with a spherical cup b adapted to receive a ball c of the same curvature. A rod d screwed into the stem is formed at the end with an interrupted marginal spherical surface f of the same radius as the ball and a central deeper hollow g in communication with notches h extending through the marginal surface so that three bearing surfaces for the ball are formed. The end of the stem is marked with a scale co-operating with an index mark on the rod d to indicate the extent to which the rod projects into the cup. The thread is of coarse pitch so that the adjustment for a whole range of viscosities takes place within one turn of the stem. A cage containing the ball is clipped around the stem a. In use the instrument is held with the ball in the cage and the latter hanging from the instrument which is then dipped and stirred in the liquid to be tested. The cage is then held and the cup allowed to rest on the ball, the weight of the parts being sufficient for this. The instrument is then raised by the handle, the ball being lifted from the bottom of the cage, and the time observed until the ball falls. The amount of the projection of the rod is adjusted until this time is standard when the amount of the projection is a measure of the viscosity.

[Also in Division E2] A jack device for raising loads, such as the sliding shuttering 5 used in continuous concrete pouring processes, in incremental steps along a vertical column 1, is of the kind comprising a frame 3 forming part of a yoke 4 supporting the shuttering 5 and a pair of vertically spaced gripping units 11, 12, each of which is adapted to grip the column 1 so as to permit upward movement of the unit along the column but to prevent downward movement. The upper unit 11 is substantially fixed with respect to the frame 3 and the lower unit 12 is slidable along the column 1 relatively to the upper unit 11 by a power-operated ram 31, which may be hydraulically or pneumatically operated. The unit 12 is coupled to a lever 29 pivoted at 30 to the frame 3 and the ram 31 is connected between the frame 3 and the end of the lever 29 remote from its pivot 30 so as to give a mechanical advantage affording at the unit 12 a force several times that exerted by the ram 31 at a location further from the longitudinal axis of the gripping units than the envelope of the load carried by the device. The unit 11 is resiliently mounted on the frame 3 being cushioned by a spring 25. A flanged stop 2 limits the height to which the device may climb. The lever 29 is biased by a spring 30 towards its return position, the movement being limited by an adjustable stop 35 used to control the lifting distance of a power stroke. A number of the devices may be set to climb together with the same lift on each power stroke. Each gripping unit 11, 12 comprises a conical housing 13 with six segmental jaws 14 acting radially to grip the column 1. A spring 19 urges the jaws 14 to the narrow end of the housing 13 to increase the wedging effect. The jaws 14 may be released by rotating a screwed tubular bush 26 to depress them against the action of the spring 19.

[Class 44] In door bolt fastenings, particularly panic bolt fastenings, of the kind employing upper and lower bolts operated by a crash-bar or other common actuating device and in which the lower bolt may be held raised when required by an automatic catch leaving the upper bolt free to be operated for securing or releasing the upper edge of the door, the upperbolt is raised by a rigid arm of an operating lever whilst the lower bolt is raised by an independent loose pivoted arm, directly operable by the lever, the arm remaining raised when the lower bolt is held raised without affecting subsequent operations of the lever and upper bolt. In the arrangement shown both bolts are lowered to effect fastening, and raised to effect release. The lower bolt 2 engages a floor socket 7 in the usual way and is held in its raised position by an automatic catch comprising an apertured clutch-plate 27 tiltable about fulcrum 28, the bolt moving freely through the aperture in the upward direction but being gripped by opposite edges of the aperture as the plate tilts to prevent downward movement of the bolt as described in Specification 589,251. The bolt may be released by slightly raising the free edge of the plate 27. The clutch described may be replaced by any other suitable form of clutch or catch. The upper edge of the door is fastened by a pivoted gravity catch 21 mounted on the fixed frame 24 and engaging behind a flange 25 on a guidefitting 6 secured to the door 4 and released by raising the bolt 1 as described in Specification 589,250, Bolt 1 is raised by an arm 11 engaging a lateral recess 12 in the bolt tail-plate 13, arm 11 being rigid with arm 9 of the lever, pivoted at 10, which carries the crush-bar 8. Bolt 1 is retracted by gravity, aided if desired by a spring 15. Bolt 2 is raised by an arm 16 similar to arm 11 but independent and loosely mounted on pivot 10. Arm 16 engages a lateral recess 17 in the bolt tail-plate 18 and has a spur 19 engaging a shoulder 20 on the operating lever so that both bolts are raised simultaneously to free the door, but bolt 2 and with it arm 16 remain raised whilst bolt 1 and arm 11 are free to fall as soon as the crush-bar is released. Normally bolt 1 rests on a fixed stop 14. In the fastening position of bolt 2 shown, arm 16 rests in strut-like manner against an inclined face 30 of recess 17 to prevent the bolt from being raised by pressure applied directly thereto. Both bolts may be released from outside by key or like means engaging and rotating a bush having an arm 31 with pin 33 engaging a recess 34 in the tail-plate 13 of bolt 1.
