Title: Improvements relating to floors, roofs and the like
IPC: E04F15/18
Filed: 1936-07-14
Abstract: 478,315. Floors and like constructions. WALKER, J. H. July 14, 1936, No. 19540. [Class 20 (iv)] A floor, roof, or like construction comprises an uncemented layer C of hard light material, such as pumice or anhydrous calcium sulphate, in the form of graded lumps or small stones enclosed or sandwiched between the structural layers, or the structural and covering layers, of the floor or the like. The pumice or anhydrous calcium sulphate may be used in graded sizes from # inch to ¥ inch, or from ¢ inch to 1 inch. Other suitable materials are foam-slag, clinker, and coke-breeze. The sound-insulating quality of the structure may be increased by adding to the pumice or anhydrite 25 to 33 per cent of granulated cork or other soft and compressible material, or by the provision of an additional intermediate stratum of such material; alternatively, or in addition, the pumice &c. layer may be underlaid and /or overlaid with insulating or waterproofing sheet material, such as one or more layers of felt, paper, or the like. The lowest layer A shown in Fig. 1 consists of a supported reinforced-concrete floor slab, and the layer C is spread thereon with the interposition of a felt layer H, which may be placed in the centre of the floor area. A concrete layer E is then cast on a sheet D of waterproofing material disposed on the layer C, and such layer may have embedded therein bands, hoops, or rings F of thin flat steel, cardboard, or other stiff material for forming controlled cracks in the layer as described in Specification 374,068. If desired, two layers of boarding, disposed at right-angles to each other, may be laid directly on the layer C. In the modification shown in Fig. 2, floor joists K are embedded in the concrete layer E, being connected together in pairs by steel rods L. To isolate different parts of the same floor from each other, the continuity of the upper layer may be interrupted where desired, for example at partitions, by the material of the intermediate layer, as shown in Fig. 2, or by thin vertical strips of paper, cardboard, cork, wood, rubber, &c. ; similar strips may be inserted where the upper layer abuts against the inner faces of outside walls, chimney breasts, &c. The layer C may be provided with embedded hoops, strips, or the like to prevent displacement of the material of the layer. The concrete upper layer may be first cast in alternate small bays, the remaining bays being cast when the concrete of the first bays has set. In another form, the upper layer. may consist of slabs, tiles, or planks which are bedded on the intermediate layer. The lowest layer may be formed of steel plates, instead of concrete. The Provisional Specification describes also the use for the intermediate layer of granulated slag, shingle, broken brick, or pumice in the form of granules of sizes varying between inch and 1/16 inch, and makes reference to Specification 404,771.

Title: A process for producing an aqueous hop extract or hopped wort
Inventor: BERG TORSTEN
IPC: C12C7/20
Filed: 1962-05-22
Abstract: A suspension of hops in water or in wort is passed through a scraped-surface heat exchanger in which the suspension is heated to produce an aqueous hop extract or hopped wort (as the case may be). After being heated, the hop extract or hopped wort may be passed with agitation through a holding chamber, flash-cooled by reduction of pressure, and then cooled in another scraped-surface heat exchanger. Whole or comminuted hops may be employed.  In the production of hop extract the water should be free from air, particularly oxygen, and the pH of the suspension should be suitably adjusted before treatment.  In the production of hopped wort the hops may be added to either sweet wort obtained by lautering the product of a mashing process or to mash in the mashing vessel at some stage prior to completion of the mashing process, the whole mash being heated in the scraped-surface heat exchanger(s); preferably the temperature and duration of the heating and holding periods are sufficient to achieve completion of the "hot break". The scraped-surface heat exchanger consists of a hollow cylinder in which there is a rotor consisting of a shaft coaxial with the cylinder, upon which scraper blades are pivotally mounted in two or more diametrically opposed rows. The hollow cylinder has a jacket for steam heating or for cooling the suspension which is supplied at one end of the cylinder and discharged at the other.  Alternatively, the rotor may be eccentrically fitted with respect to the axis of the hollow cylinder, as described in Specification 842,310.  The suspension may be heated in two or more stages in two or more scraped-surface heat exchangers.

Title: Improved mechanism and method for manufacturing tubes and product thereof
IPC: B21C37/08
Filed: 1956-06-26
Abstract: 798,495. Seaming non-metallic sheet materials. AMES IRRIGATION PTY., Ltd. June 26, 1956 [June 27, 1955], No. 19720/56. Class 42 (1). [Also in Groups XXII and XXVIII] A longitudinally seamed tube is made from flat strip stock by forming the strip with edge flanges and bending it to cylindrical shape with the flanges abutting, trimming the flanges, welding trimmed flanges together to form the seam and cold working the welded seam. Metal strip 20 of aluminium, stainless steel, steel, copper or brass from a reel 21 passes over an idler roller 26 to two pairs of flanging rollers 30, 31 and 32, 33, normally idle but driven when the leading end of the strip passes therethrough, which form the strip with flanges 35, then through rolls 38 which help to form a sharp crease at the flanges and under hold down rolls 43. The flanges are cleaned by brushes 47 and the strip is bent up by twisted converging guide stringers 40, 41 having facings 42 which engage the flanges 35 and guide them towards each other. Guide rollers 45, 46 may support the partly formed tube internally towards the end of such operation. The partly formed tube is then brought into cylindrical shape by a cluster 50 of outer rolls 51, 52, 53, 54 and inner rolls 55, 56 the rolls 51, 52 being driven and the roll 51 grooved at 57 to accommodate the now abutting flanges 35. A cylindrical mandrel 60 with longitudinal tube-engaging " Micarta " (Registered Trade Mark) strips 61, 62, 63, 64 supports the tube internally before and after such operation. The tube with the flanges 35 held against one another by guide bars 70, 71 and supported by the mandrel 60 passes to a milling cutter 74 which trims the flanges until they project about the thickness of the metal. The flanges are then welded together by a gas shielded arc welder 80, or by resistance welding, the support or back-up strip 61 on the mandrel 60 having a shallow recess 82 to prevent scorching. A girdle 81 surrounds the tube to prevent distortion during welding. Further to prevent such distortion that part of the strip 20 to form the lower part of the tube may be preheated by gas heaters 83 during the bending up thereof. The welded tube is permitted to cool as it moves along supported by the strips 62, 63, 64 in the mandrel 60 and by another girdle 85 to prevent deformation. The tube then passes through three sets of driven rolls 86, 87, 88 the top rolls 89 of which are preferably slotted, so as not to touch the actual seam, and water cooled. The weld, having been cooled to about 250-300‹ F., is cold worked and flattened between a roll 90 and a back-up roll 91, rolls 92, 93 helping to propel the strip and formed tube. Lengths of the tube may then be cut off by a travelling saw. The strip and tube formed therefrom may be of plastic.

Abstract: 147,753. Ges. f³r Drahtlose Telegraphie. Oct. 23, 1918, [Convention date]. Addition to 145,629. Bearings, determining wirelessly; aerials.-In the apparatus for determining the direction of electromagnetic waves, comprising the small rotatable coil, tuned circuit, and amplifierdetector described in the parent Specification, to obtain a sharper minimum the non-directional effect of the electric field upon the apparatus is counterbalanced by connecting simple wires of suitable capacity to the coil. In the arrangement shown in the Figure a short aperiodic aerial 5 is connected through a variable condenser 6 to both sides of the condenser 2 in the coil circuit. The effect of the electric field is neutralized in the receiver by the adjustment of the condenser 6. The Specification as open to inspection under Sect. 91 (3) (a) states that the connecting wires between the aerial coil and the receiving apparatus are placed at right-angles to the direction of the electric field, i.e. horizontally. According to another method, the electric field is screened off by means of a horizontal wire netting arranged over the coil and receiving apparatus and earthed at suitable places, This subject-matter does not appear in the Specification as accepted.

Filed: 1966-05-05
Abstract: 1,083,375. Record retrieval. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 5, 1966 [May 27, 1965], No. 19904/66. Headings G4A and G4C. In a record retrieval system, indicia for records retrieved are stored and retrieval of a record already retrieved is prevented. When any one of a plurality of processors attempts to access a record in a bulk storage unit (disc or strip), the record address is compared in turn with the addresses of records already accessed but not yet replaced. These addresses are stored in respective rows of an auxiliary store, the rows being scanned by a binary counter until equality is obtained in the comparison or the maximum count is reached. If equality is obtained, the requesting processor is signalled that it must wait. If the maximum count is reached, however, accessing of the bulk storage proceeds and the address is stored in the first free row of the auxiliary store, located by scanning. When the processor returns the record, its address is located in the auxiliary store by the successive comparison process, and deleted. Each row of the auxiliary store stores its own (row) address in one of two sections thereof to indicate whether or not the row is free (used for addressing the auxiliary store). The section used when the row is free may store the invalid (row) address 15 (equal to the said maximum count) when the row is not free, this being used to cause continuation of said search for a free row. One of said two sections may be dispensed with. Accessing may be associative in which case the auxiliary store may hold the keys rather than addresses of accessed records, or the address may form part of the record, be accessed first and used as above.
