Title: Improvements in or relating to the preparation of sheets of cellular material
IPC: C08J9/06
Filed: 1958-06-04
Abstract: 897,219. Preparing cellular sheets of synthetic resins. SPECIALTY CONVERTERS Inc. June 4, 1958 [June 5, 1957], No. 17780/58. Class 87(2). [Also in Group VIII]. A cellular sheet e.g. of polyurethane or a polyvinyl chloride plastisol, is formed by applying a layer of a fluid mixture, in which a gas is generated at a certain temperature, to an imprevious surface whilst at a temperature below the gas-generating temperature, placing an impervious sheet in contact with and completely covering the layer, and raising the temperature of the assembly to generate gas and form cells within the layer. The cellular sheet thus formed has a negligibly thick skin of higher density. In one example the reaction product of toluene di-isocyanate and polypropylene glycol admixed with further toluene diisocyanate and a silicone oil is cooled to oC. and mixed with aqueous N-methyl morpholine and triethylamine, also al-oC. The chilled mixture is placed in a reservoir 10 having a refrigerating coil 32 to be spread by a knife 12 as a layer on a moving sheet 22 of silicone treated glassine. As the layer leaves the knife 12 a cover sheet 18 of polyethylene is applied thereto from a roll 36, and the assembly moves over a table 28 to be heated by the atmosphere, or by heating means (not shown) so that a gas generating reaction takes place in the layer to form a self-supporting cellular sheet 40 of polyurethane. The sheets 18, 22 are stripped from the sheet 40 and wound on rolls 46, 48. In other examples the cellular sheet is made (a) of polyurethane derived from a polyester resin, toluene diisocyanate ; and N-methyl morpholine, and (b) from a polyvinyl chloride plastisol mixture containing a blowing agent. Other materials specified for use as the supporting sheets are metal foil, sheet metal, wood, kraft-paper coated with a silicone, and rigid or flexible synthetic materials, and for use as the covering sheets are paper treated with a silicone, polyethylene, or wax, polytetrafluorethylene and polychlorotrifluorethylene. The method may also be used for making a composite assembly comprising a cellular polyurethane sheet bonded on one or both surfaces to a sheet of regenerated cellulose, cellulose nitrate, acetate, or acetate butyrate, ethyl cellulose, vinylchloride vinyl acetate copolymer, polyvinyl butyral, polystyrene, modified styrene, polymers, rubber hydrochloride, polyamide, polyethylene terephthalate or other polyester, or vinyl chloridevinylidene chloride copolymer.

Title: Digital data processing apparatus
IPC: G06F11/34
Filed: 1971-05-28
Abstract: 1321736 Digital computers; diagnostic programme INTERNATIONAL BUSINESS MACHINES CORP 28 May 1971 [19 June 1970] 17813/71 [Also in Division G4A] A digital computer uses a tracing (i.e. diagnostic) programme which executes each instruction of a traced programme in turn, the results of the tracing programme being analysed and passed to an output device. While this occurs the traced programme is being executed in the same sequence as usual but it is under the control of the tracing programme. The tracing programme controls all the other programmes in the system including any supervisory operating programme. A hardware instruction counter always points to an instruction in the tracing programme, never to an instruction in the traced programme, thus each traced programme is copied into the tracing programme in turn. The traced programme is being executed in its normal sequence and the address of the next traced programme instruction to be processed is contained in a pseudo instruction counter which is updated by the tracing programme. The tracing programme sequence is described in great detail (Figs. 3A-3E, not shown) and the results are passed to an analysis programme (Fig. 9, not shown) which can present the desired results in a number of different formats for output to magnetic tape or a printer. The tracing programme may only operate for selected sampling periods under operator control, e.g. from a typewriter, and punched cards can be entered to select different desired parameters for tracing or analysis. The computer can be multiprogrammed and interrupts are dealt with by masking after the tracing programme has been completed.  Other features mentioned include magnetic core and tape storage, floating point, detection of addressing errors, conditional branch instructions and hexadecimal numbers.
