Title: Improvements in or relating to methods of and means for foaming thermoplastic synthetic materials
Inventor: BUCHMANN RUDOLF
IPC: B29C44/34
Filed: 1958-08-26
Abstract: 900,942. Chambers for heating thermoplastic particles. MATZLER, W., [trading as MEDULTRA W. MATZLER]. Aug. 26, 1958, No. 27295/58. Class 64 (2). In a container 1, superheated steam or hot air passes, e.g. from nozzles 6 (selected for greater flow nearer the bottom) in hollow, stirring arms 3 or from perforations in a double wall, into a mass 12 of polystyrene particles containing expanding agents, so that each particle expands to a cellular condition ready for use in moulding. The container is charged initially with particles already expanded so that fresh, unexpanded particles fed in from a hopper 7 and spread by a distributer 13 are heated gradually at first. The apparatus is for batch or continuous operation. When the level of the particles reaches an element 11, an outlet 8 is opened until it is closed by the action of an element 10 when the level falls. The heights of the elements 10, 11 are adjustable to control the density of the product but partiallyfoamed material may also be taken off from upper outlets 14. Members 15 on the container wall increase the turbulence. The container may be tilted and the hot fluid supplied from the underneath of the container wall or the container may be pivotable to the horizontal position so that the movement of the particles can be varied. The heating fluid may be introduced separately from the stirrer, through fixed pipes and it may be introduced through perforations in a double-walled portion of the container 1. The stirrer may be stationary and the container rotated. In the event of power failure, the particles are automatically cooled by the introduction of air or by dousing with water and a wetting agent to prevent them fusing together.

Abstract: 918,398. Electric calculating apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 31, 1961 [Aug. 2, 1960], No. 27666/61. Class 106 (1). In . a hybrid arithmetic unit digital and analogue computations are combined, digital signals heing applied to digital-to-analogue converters whose analogue outputs are arithmetically combined in a common output circuit. The transmission of the analogue outputs to the common circuit is selectively controlled by digitally controlled switching circuits. In the specific embodiment, analogue inputs on lines 100 are selected by digital signals M1- M4 which control gates 80a-80d. The selected analogue signal acts as reference level to a digital-toanalogue converter 82a which is fed with digital signals D1. The analogue output A1 representing the product of the two signals, passes through amplifier 102a and is converted to - A1 This signal feeds a gate 90b and also forms an input to gate 104a of the second level of the apparatus. Digital signals N1, N2 control gates 90a, 90b, the analogue output of one of these gates being combined with digital input D2 in converter 84a to give a signal - A2. Amplifiers 106a, 106b give outputs A2, - A2. By means of gates 94a, 96a, 98a and their associated digital control signals V1, S1, S2, either ground voltage, voltage A2, or voltage - A2 is applied to resistor 108a. The voltages from the various levels of the apparatus combine at point 116 to form an input to a digitally controlled variable gain amplifier 120, 122. Its output A17 is fed either to converter 123 or to converter 124 via digitally controlled gate 125a or 125c. The converter not fed with A17 is fed with an analogue signal via gate 125d or 125b. Both converters feed a comparator, and when the signals compared are equal, the digital input F2 or F3 will be the result of the computation, or its inverse, dependent upon the control on gates 125. The apparatus is incorporated in a digital computer, the arrangement being described with reference to Fig. 13 (not shown).
