Title: Construction of roofs
IPC: E04B7/14
Filed: 1956-06-27
Abstract: 807,567. Roofs. VIERA, L. I., and FRAVEGA, L. A. J. M. June 27, 1956 [June 28, 1955], No. 19945/56. Class 20(4) A method of constructing a roof which comprises anchoring each end of a plurality of cables to a supporting member so as to extend said cables over the roof area spaced apart from one another, placing blocks on said cables to substantially cover the roof area, grouting said blocks, said blocks having a separation between them, and allowing the grout to set, and after the grout has set adjusting the tension in said cables to apply a compressive force on said grouted blocks. As shown, Fig. 2, the radial cables 2 of a steel framework, also comprising a number of wire rings 4, are suspended between a central member 3 and the upper rim 5 of a circular wall 1, the framework being designed to support blocks 10 which are located in the spaces between the cables and rings, a binding material, e.g. mortar, being grouted into the spaces between the blocks. After the grout has set, nuts 6, on the threaded outer ends of the cables, are tightened against a plate 8 and a rim 9 which extend around the rim 5 of the wall 1, the cables thus, being tensioned to apply a compressive force to the blocks 10. Small moulds, not shown, may be temporarily erected beneath the spaces between the blocks, in order to prevent chipping of the grout. The whole roof may be covered by a thin layer of concrete. In the case of quadrangular roofs the central member 3 may be omitted. In a modification the central member 3, Fig. 2, is supported by a central column, not shown. An alternative method of tensioning the cables 2 comprises applying weights to the blocks, after they have been placed on the framework, and then grouting the blocks in. When the grout has set the weights are uniformly removed. If it is desired to improve the thermic, or acoustic, qualities of the structure a sub-ceiling can be suspended from the cables 2 to provide a flat, or bell-shaped soffit surface.

Title: Improvements in and relating to sound transmitting and receiving apparatus
IPC: G01S1/72
Filed: 1920-07-09
Abstract: 147,940. Signal Ges. Aug. 6, 1917, [Convention date]. Subaqueous audible signals.-Coils attached to the oscillating parts of electro-magnetic transmitters and receivers are liable, owing to the comparative looseness of their structure, to introduce excessive damping and an indeterminate inertia effect. Various expedients are adopted to avoid this difficulty. The coils may be Bakelized in grooves or slots, as shown in Fig. 1, so as to be rigid with their supports; or they may be carried by weak springs between washers of soft material, or attached to the vibrating structure at a nodal line, so as not to partake of the vibratory movement. An arrangement of the last kind is shown in Fig. 3, in which the diaphragm 1 is formed with a profile as shown at 14 so as to vibrate with a node circle at 15, where the supports for the coil 5 are attached.

Filed: 1926-08-14
Abstract: 270,531. Allinson, C. P. Aug. 14, 1926. Thermionic amplifiers. - To ensure stability and freedom from parasitic oscillations, the input and output are arranged across the diagonals of a bridge, the elements of two arms of which are the plate-grid and grid-filament capacities of the valve, while the balancing arms comprise variable condensers K, K<1>, or inductances L, L<1>. Fig. 1<a> shows tuned input and output circuits I, O, respectively, the input being across diagonal X, G, and the output across diagonal F. P. A high resistance or choke H, R is inserted in one of the positions shown when balancing condensers K, K<1> are employed to prevent isolation of the grid G. In an alternative arrangement variable inductances are substituted for the condensers E, K<1> in which case'a blocking condenser is necessary to prevent short-circuiting of the high tension. In a further modification the high tension supply mav be connected through a choke to the plate and a tapping on the output inductance serve as the point X instead of providing additional inductances. Fig. 4<a> shows an arrangement in which the bridge is re-arranged and the input I is across diagonal GF and the output across diagonal PX. Similar modifications may be made as in the previous arrangement. When condensers are substituted for the inductances L, L', the input instead of the output inductance is tapped, and the tuning inductance serves as two arms of the bridge. Specification 240,114 is referred to.

Title: Shoemaking apparatus
Inventor: COHEN HAROLD WILLIAM
IPC: A43D111/00
Filed: 1951-08-28
Abstract: 702,486. Conveyers; rope railways. BEE BEE SHOE CO. Aug. 28, 1951, No. 20209/51. Classes 78 (1) and 104 (2) [Also in Group VII] An apparatus for a continuous boot making process has a number of work stations arranged round a conveyer system for last, and/or shoe component carriers. The conveyer runs continuously and means are provided for arresting the carriers as desired. The last carriers comprise a plate 13, Fig. 7, running in grooves of track rails 10, 11 and a spindle 14 mounting a last pin 15. Driving devices comprising plates 27 attached to conveyer belts 23 have spring loaded balls 29 which engage nuts 20 on the last carriers but which allow the belts to slip if the carrier is stopped. The lasts are stopped by releasing a spring loaded pin 42, by a treadle connection 45 to allow them to extend into the path of spindles 14. To avoid overloading the belts 23, the driving plates are spaced by a distance which is not a multiple of the distance between successive nuts 20. In order to space the carriers correctly for some operations plates 46, 47, Fig. 8, pivoted at 48, 49, are spring urged to contact at their notched end 52. A spindle 14 parts the plates as it approaches their converging sides and thus closes the entrance end to stop following carriers until the notch 52 is reached. In use, work stations are provided on either side of outward and return conveyer runs and last carriers 13 are fed in by hand, preferably alternately, with similar component carriers 33, Fig. 8, and at the end of the outward run the last carriers contact; each other until engaged by rotating arms for transfer to the inward conveyer. The plates 13 of the last carriers are rectangular, while those of the component carriers 33 are square so that at the end of outward conveyer the latter can be pushed off at right angles on to a, return conveyer. The working stations for the manufacture of a conventional, slip lasted platform shoe are described in detail and include cement spraying booths, and also stations at which drying is carried out by infra-red lamps.

Abstract: 1,261,091. Hospital patients gowns. T. BRADLEY. 22 April, 1969 [12 March, 1969], No. 20425/69. Heading A3V. A disposable patient's gown, for use during examination or surgery, is made from a single sheet of a material, such as paper, having stripes of adhesive, coated on both mating surfaces 62 and 64 or 86 and 90, or on only one of each pair of such surfaces and arranged so that, after initial adhesion, these edges may be pealed apart and re-attached. The adhesive is composed of an aqueous solution of latex, containing casein to reduce adherence, tackifying resins, cellulose thickeners and unspecified defoamers, wetting agents, antioxidants and preservatives. When used on both the mating surfaces, the stripes are treated with talc to reduce the adhesive/adhesive adherence or, alternatively, the effective adherence is reduced by applying the composition in patterns (Figs. 11 and 12, not shown), which are not exactly coincident on initial adhesion, so that on separating the surfaces, the patterns are only partially torn away, leaving unused parts of the adhesive for re-attachment.
