Title: Apparatus for the infeed of printed products to a stacker
IPC: B65H29/50
Filed: 1976-10-01
Abstract: 1515440 Stacking sheets FERAG AG 1 Oct 1976 [8 Oct 1975] 40780/76 Heading B8R Overlapping sheets 12 on a belt 11 are transferred to a gripper chain conveyer 18. In the downward run 27 of this conveyer, a loop 27<SP>1</SP> is formed, the vertical position of which is determined by a stack height sensor 57-61, so that the sheets are transferred, via a belt 52, which moves vertically with the loop onto a circular stack supported by a disc and core 114, 115 on a turntable 51. The gripper chain input may also be formed by a vertically adjustable chain loop 37<SP>1</SP>. Photoelectric detector 80 stops the drive to the conveyer 18 and turntable 51 when sheets are absent, and detector 81 starts the drive when sheets are present. When limit switch 73 is tripped by the frame 23, sheet infeed is stopped or diverted and the conveyer 18 and turntable 51 are stopped when detector 82 senses passage of the last sheet. Sheet counters may replace the limit switch 73.

IPC: H05B6/02
Filed: 1958-12-19
Abstract: 855,987. Heat treating. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 19, 1958 [Dec. 24, 1957], No. 41067/58. Class 72 [Also in Group XI] In annealing work pieces which have highly different wall thicknesses in the direction of their major dimensions the thick-walled parts of the work piece are heated by one inductor and the thin walled parts by a second inductor. As shown, work pieces 6, e.g. cartridge cases, are fed from a channel 7 to holders 5 on a conveyer chain 4 driven by sprocket wheels 2, 3 so that thick walled portions enter the working space of an elongated induction loop 9 and are preheated to a temperature lying below the final desired value. The work pieces are then transferred by an ejector 11, positioned a short distance before the closed end of the loop 9, into the working space of a second inductor 12 which acts upon the whole work piece and heats to the desired final temperature the preheated portion of the work piece simultaneously with the thin-walled parts of the work piece.

Abstract: 1,188,616. Digital transmission systems. SIEMENS A.G. 30 Aug., 1968 [1 Sept., 1967], No. 41405/68. Heading H4P. A programme-controlled digital data exchange includes a central store KS, which stores the programmes and the relationships between feeders Z and receivers A, and an intermediate store Sp, code conversion, speed changing, and timing correction being performed in the exchange. A change in information received from a feeder Z is passed via an address register AR to an appropriate cell in store ZZ. The change, together with the address of the required receiver indicated by ZZ, passes via register WR and converter ACW to the relevant receiver A. Timing correction of the characters stored in ZZ takes place bit-wise. Speed changing and code conversion take place under the control of programmes stored in KS. Data can be passed to the intermediate store Sp, and is extracted when required by a programme. If the exchange consists of several parts the data is sent in blocks at high speed from one part to another.

Title: Extracting pertussis antigen
IPC: A61K39/10
Filed: 1966-09-21
Abstract: A solution of immunoprotective antigen is prepared by extracting cells of Bordetella pertussis with an aqueous 0.75 to 2.25 molar solution of lithium bromide at a pH above 6.0 but below 8.5 and at a temperature below 25 DEG C., and then separating cell debris from the extract.  The antigen itself may be prepared by dialysis of the extract to remove lithium bromide, followed by acidification to pH 4.6 to 4.8 to precipitate the antigen.  The extractant solution preferably contains a buffer such as tris(hydroxymethyl) amminomethane, or borate or barbital salts; a chelating agent such as ethylenediaminetetraacetate or trans-1,2-diaminocyclohexanetetraacetate; and an antioxidant such as b -mercaptoethanol.  Before extraction, the cells are preferably washed with water or saline, and the washings may be added to the extract prior to precipitation of the antigen, or treated separately to precipitate any antigen present and the yield combined with the main preparation.  The precipitated antigen may be reconstituted with an injectable aqueous medium and used as a pertussis vaccine.  It may also be adsorbed on a carrier, e.g. aluminium hydroxide or phosphate, to provide an adsorbed antigen vaccine or combined, in solution, with vaccines for tetanus, diphtheria and poliomyelitis to give a polyvalent vaccine.

In a method of explosively bonding at least two metal layers, the layers are initially spaced apart by crinkled ribbons of metal which are positioned so that their width defines the spacing between the layers at least at a number of points along the ribbons. The ribbons may be bent into regular sine wave or regular angular zig-zag shape or may be twisted spirally and are at least 0À025 cm. wide. The ribbons 3, Fig. 1, are arranged between a metal base layer 2 and an upper metal cladding layer 1 which is covered with a layer 4 of detonating explosive to which is attached an electric blasting cap 5. In examples, the cladding layer is an oblong stainless steel plate, the base layer is a carbon steel plate, the stainless steel plate is covered with a layer of a grained amatol explosive comprising 50 parts ammonium nitrate (A.M.) and 50 parts trinotrotoluene (T.N.T.) in a wooden frame covered with a layer of waxed paper and the detonation is effected at the middle of one of the sides. Uniform bonds result using two sine wave iron ribbons spot-welded on edge to the backing plate parallel to the longer sides, two spirally twisted iron ribbons spot welded parallel to the longer sides or two rows of three zig-zag ribbons. Unsatisfactory welds are produced using the ribbons parallel to the short sides of the plates. In a further example, a copper plate is supported above a mild steel backing plate by 20 mild steel sine wave ribbons spot welded on edge to the backing plate in the mainly radial pattern shown in Fig. 5 (not shown), the copper plate is covered with a layer of 80 parts A.M., 20 parts T.N.T. in a wooden frame covered with waxed paper and sand and the explosive is detonated electrically in the centre. Copper sine wave ribbons or steel twisted ribbons may be used instead. In another example, a stainless steel plate is supported above a mild steel backing plate by five iron sine wave or spiral ribbons arranged to radiate from a corner as in Fig. 6 (not shown), the stainless steel plate is covered with A.M. T.N.T. explosive detonated at a corner. In yet a further example, a mild steel plate is supported above an oblong mild steel backing plate by seven spot-welded sine wave iron ribbons, five along the length of the plates and two along the short edges, the upper plate is covered with a 50/50 mixture of sodium chloride and AM. T.N.T. explosive in a wooden frame, the four edges of the assembly are sealed and the space between the plates is evacuated and detonation is initiated at a point halfway between the long sides but near one end. The ribbons may be glued in position.
