Filed: 1973-10-09
Abstract: 1423243 Cutting apparatus FRAMA AG 9 Oct 1973 [9 Oct 1972] 47102/73 Heading B4B A device for cutting open envelopes comprises a conveyer 3 for moving an envelope with its edge to be cut along a guide surface defining a first vertical plane, a pair of co-operating cutters 10, 11 defining a second vertical cutting plane which is adjustable with respect to the first plane, a sensing member 35 engageable by the envelope as it moves along the guide surface and an adjusting mechanism responsive to the movement of the sensing member to move at least one of the cutters so that the cutting plane is moved relative to the plane of the guide surface as a function of the thickness of the envelope sensed by the sensing member. The guide surface is defined by a wall 5 extending vertically from a horizontal envelope support surface 4 of the device. The cutters comprise a member 11 mounted on a shaft 15 which is rotatable in a wall 8 of the device, the shaft being rotated by a motor 50 via a belt 13; the shaft 15 also rotates the conveyer belt 3 whose upper reach extends through a slot 9 in the support surface 4. The upper cutter 10 is fixed to a shaft 21 which is rotatable in bearings 27, 28, Fig. 3, and may be driven by its own motor or by a belt from the shaft 15. The cutter 10 is secured to a block 20 housing a thrust bearing 22 which, via a plate 26, contacts an actuator disc 25. The disc is formed with cam-shaped recesses 37 which co-operate with balls 36 abutting a disc 32; the disc 25 is provided with a lever portion 25a which is coupled by a pin 44 to the envelope-thickness sensing member 35. In operation, when an extra thick envelope passes under the sensing member, the latter pivots thereby causing the disc 25 to rotate slightly and thus, via the ball and recesses 36, 37 move the cutting edge of the cutter 10 further away from the guide surface 5. In order to accommodate the latter adjustment, the axial width of the peripheral surface of the cutter member 11 is sufficient to allow the cutting edge to move across; the member 11 is urged by a spring into contact with the cutting edge. In order to adjust the initial setting of the cutting edge relative to the guide surface the disc 32 is threaded on to a sleeve 31, Fig. 3, so that by rotation of the disc its axial position is altered; notches 33 are provided in the periphery of the disc 32 so that the latter can be locked in a set position by means of a pawl (34) Fig. 4 (not shown) engaging a selected notch.

Title: Method of producing heat and cold-insulating sheet material using a layer of foamed plastics
IPC: F16L59/02
Filed: 1967-10-17
Abstract: 1,211,355. Foamed plastics laminate; moulding plastics material. PAPIERFABRIK G.m.b.H. 17 Oct., 1967 [18 Oct., 1966; 17 Feb., 1967], No. 47195/67. Headings B5A and B5N. [Also in Divisions A4 and B8] A method of producing heat and cold insulating material consisting of or comprising a layer of foamed plastics includes the steps of mixing together at least two basic components which react with one another with one or more activators to form foam, directing the mixture towards the gap 26 between two moving supporting webs 14, 16 and moving the mixture and the webs between web guides in the form of a pair of rolls 10, 12 or bars, and then between gauging plates 50, 52, the distance between the plates determining the thickness of the layer of foam between the webs and this distance being adjustable by moving the plates towards or away from one another, the distance between the rolls or bars also being adjustable. In the device shown for carrying out the method the reaction mixture is deposited as a jet or spray from a nozzle 28 on to the web 14 as the latter passes from a roller 13 to rolls 10, 12. The mixture forms a bulge 15 ahead of the rolls and is reciprocated horizontally to spread the mixture evenly. Alternatively the transverse speed of the nozzle or the flow of mixture may be varied to ensure even spreading. More than one nozzle may be used. The assembly 48 of foaming mixture and webs 14, 16 then passes between roll 10 and adjustable roll 12 and then between plates 50, 52 which may be heated and/or cooled plates. The webs may be advanced by belts 21, 23. The width of the foam is controlled by edge guide rails or air jets blowing on the foam. One or both of the webs 14, 16 may have an adhesive repellent silicone based coating to enable it or them to be stripped from the set foam. In this case the coated  web(s) may be endless. The webs may be of paper, cardboard, plastics material, textiles, metal foil, or veneer. The foam may be produced by the reaction of polyisocyanates with polyether or polyester compounds with tertiary amines, or mixtures of organic tin compounds and water, as activators. An intermediate layer of metal, plastics, organic or inorganic fabric or threads may be inserted in the foam. In a second embodiment the roller 13 and belts 21, 23 are omitted. The materials produced are shock absorbent and may be used in packaging e.g. as boxes, containers, pouches, or in chests.

Abstract: 1442661 Automatic control of temperature CROMPTON & KNOWLES CORP 10 Oct 1973 [13 Dec 1972] 47366/73 Heading G3R In order to reduce thermal inertia effects and overshooting in the control of an extruder barrel temperature, the extruder barrel 12, Fig. 2, with liner 13 is surrounded by a shell 16 of a material, e.g. aluminium, having a total heat capacity (i.e. the product of the specific heat of the material and weight) of not less than 0À5 times and not more than 1À5 times that of the barrel e.g. steel. Probes 28, 32 produce electrical output proportional to the temperature of the barrel and shell respectively. A unit 34 compares the average of the two outputs, as a measure of the instantaneous average of the two temperatures sensed; with a set value to produce an error signal. The error signal is used to selectively actuate, via a respective relay switch (R 1 ) (R 2 ) Fig. 3, (not shown), either a solenoid valve (26) controlling the supply of coolant (e.g. water) through tubes 18 in the shell, or, an electrical heating element 20 whereby to maintain the barrel temperature substantially constant within a tolerance range. More weight may be given to the barrel temperature by - (a) amplifying the barrel probe output, (b) having one or more additional barrel probes or (c) using a barrel probe having a higher output/ degree temperature than the shell probe.

Abstract: <PICT:1092629/C2/1> Acetone is separated from a mixture obtained by the oxidation of a light distillate petroleum fraction by submitting the mixture to liquid-liquid extraction with water, separating the aqueous phase from the hydrocarbon phase, and subjecting the aqueous phase to hydro-extractive distillation.  In an example, a mixture containing acetone (37.5%), methanol methyl acetate, C5-C7 aliphatic hydrocarbons, and benzene, together with minor proportions of methyl ethyl ketone, methyl n-propyl ketone, lower aliphatic acids and water is fractionated in column 10, and the distillate is extracted with process water in column 20.  A liquid stream, rich in hydrocarbons is withdrawn through line 22.  The extract from the base of column 20 is distilled in column 30, which is supplied, through line 42, with process water at 25-30 DEG  C.  The bottoms fraction from column 30 is fractionated in column 40 to give a head product which contains 96.6% acetone and 2.5% methanol.  The water withdrawn from the base of column 40 is recycled to columns 20 and 30. The overhead product from column 40 may be submitted to further hydroextractive distillation in order to eliminate methanol.

The invention relates to a monopulse radar, one channel, e.g. azimuth, of which is shown in Fig. 3. The signals from the two receiving antennµ 1, 2 are fed to magic T means 3 to produce sum #S and difference #D voltages. These RF signals are converted at 15 and 16 into IF voltages, to become #s and #d respectively, and are then fed to a 3db coupler 20, to produce two signals - The off boresight target deviation is proportional to /D/=/d/ or (tan #), Fig. 2 (not shown). The /#S/ /#s/ phase angle (#) between #r1 and #r2 is given by Thus, by measuring (cos #) in a demodulator 25, the output 26 can represent said target deviation. An alternative way of obtaining #r1 and #r2 is shown in Figs. 4, 5 and 6 (all not shown). Fig. 4 shows a constant impedance (R 0 ) network,   When R 0 <SP>2</SP> L/C whence a signal #s at the input produces voltages across the two output resistors, equal in magnitude; but in phase quadrature. Fig. 6 shows two such networks having   #s and #d as inputs, and their outputs combined by two networks as shown in Fig. 5. The final   outputs #a and #b across the resistors 33 represent   for phase measuring purposes, the signals #r1   and #r2. To test whether spurious differential phase shifts have been introduced, the difference signal #d is periodically suppressed, whence any output at 26 (which should be zero) is used to control a phase shifter in one of the channels to the demodulator.
