Title: Tray for crockery or other articles
IPC: A47L15/50
Filed: 1977-07-04
Abstract: In crockery racks, the problem arises of adapting the rack height to the multiple design shapes and sizes of crockery. In order to be able to produce an appropriate rack height, the corner regions of the rack (1) and of a frame (7) which can be placed on top are fitted with sleeve-type or plug-type corner parts (8, 9). Plug-type or sleeve-type adaptor pieces (10) are fitted onto or inserted into the corner parts as spacers between the rack (1) and the frame which can be placed on top and thus for the variable design of the height of the crockery rack. Depending on the required height of the crockery rack, shorter or longer adaptor pieces (10) can thus be used. <IMAGE>

Title: Improvements relating to the granulation of iron or slag
Inventor: STORR HARDY ERIC
IPC: C21B3/08
Filed: 1960-08-16
Abstract: <PICT:0991600/C6-C7/1> Iron or slag is granulated by directing a stream of molten iron or slag through the atmosphere, subjecting the stream to water jets of temperature at least 60  DEG C. to create a shower of hot particles and water, and collecting the falling particles in a vessel containing water of temperature at least 80 DEG C.  For example, pig iron or slag from a blast furnace is poured into a tipping ladle 1 which discharges it via a surge pool 4 down a dividing sand-lined conduit 5 to form molten ribbons which are acted upon by hot water jets from spray heads 10. The resulting particles fall into hot water in a tank 14 and sink on to conveyer 25 through the open base of hopper 23 immersed in the tank to be continuously removed. The temperature of the hot water in the tank may be controlled by adding controlled amounts of cooling water, e.g. via valve-controlled supply pipes 32 and 37 ; the level of the hot water may be varied by adjustable weirs 15 and 16.

Title: Timing mechanism for valves or switches
IPC: F23N5/22
Filed: 1933-10-13
Abstract: 427,176. Time - operated valves. McDOWELL, H., 9038, Phyliss Avenue, Los Angeles, U.S.A. Oct. 13, 1933, No. 28364. [Class 135] [See also Group XXXVII] Apparatus for operating a valve or electric switch after a predetermined time has lapsed comprises a spring 35 operatively connected to an actuating member 26 for operating, for example, the plug 15 of a cock 10, a clockwork timing mechanism 64, 63, 51, and a flexible and resilient detent 38, 44, 40, cooperating with teeth 45 on the actuating member 26 to prevent actuation until released by the timing mechanism. The detent mechanism is set and the spring 35 tensioned on opening the cock through the lug and slot engagement 30, 32, one end of the spring 35 being secured at 36 to the actuating member 26 and the other at 37 to the arm 38 of the detent mechanism which arm is pivoted at 39 on a floating link 40. The detent is released when the finger 43 of the arm 38 drops into a slot 50 in a timing wheel 47 and the teeth 45 are so shaped that the tension of spring 35 causes them to ride over the dog 44, thus allowing the actuating member 26 to operate to close the cock. The lug and slot engagement 30, 32, of the plug 15 with the member 26 allows adjustment of the valve without disturbing the timing mechanism. The predetermined time interval before operation is dependent upon the position of the finger 43 of the detent arm 38 with respect to the slot 50 in the timing wheel 47 which is adjusted by winding the spring 57 of the clockwork mechanism the requisite amount by means of a minute indicating wheel 68 which is further geared to an hour indicating wheel 69.

Title: Improvements in or relating to a flexible web or sheet composed of fibrous materialsagglutinated by adhesives
IPC: D04H1/66
Filed: 1950-11-21
Abstract: 693,711. Agglutinated fibrous sheet materials; compound sheet materials. INTERNATIONAL CELLUCOTTON PRODUCTS CO. Nov. 21, 1950 [Aug. 4, 1950], No. 28416/50. Class 140. A flexible, porous, fabric - like sheet material. comprises a web of fibres, e.g. carded or air-laid, having its porosity increased by stretching to separate the fibres, and strengthened by the application of a number of lines of binding material. The binding material may be one which becomes stronger when stretched and the fibrous web may be stretched in the direction of the lines of binding material after application. The lines may be applied cross-wise of a web in which the fibres, although haphazardly arranged, tend to lie longitudinally and the web is then stretched cross-wise. Further adhesive lines may then be applied length-wise and the web stretched lengthwise. The adhesive may be softened by heat or solvents for stretching, or the web may be stretched before the adhesive has set. The web may be creped, calendered, embossed, subjected to a brushing operation before or after stretching. The stretching and brushing, if any, cause gathering or bunching of the fibres along the lines 6 and 7 of adhesive. Porosity may be further increased by removing a proportion of the fibres of the finished web. For instance short fibres may be included and subsequently shaken, blown or sucked out, or soluble fibres, e.g. polyvinyl resin fibres, may be dissolved out. A web bearing a net-like pattern of adhesive, e.g. crossing lines, may be permitted to shrink slightly from a stretched condition, which causes the areas of fibre surrounded by lines of binder to pucker or puff from the plane of the web. Laminated webs may be produced with layers of the same or different fibres. Two webs may be printed with lines of adhesive, crosswise on one web, lengthwise on the other, and assembled with the printed faces in engagement after the adhesive is too set to bond to additional fibres but will still bond to similar adhesive. Alternatively, a single web may be printed with adhesive lines which extend through the web, and assembled between two outer webs while the adhesive is still liquid. The fibres may be cotton, wool, silk, rayon, synthetic fibres, flax, sisal, hemp, jute, asbestos, and glass. The adhesive may one of several specified vinyl polymers and copolymers, polythene, nylon, cellulose acetate, hydroxymethyl cellulose. or carboxymethyl cellulose, and may contain fibres.
