Title: Process for producing deeply embossed thermoplastic sheets
IPC: D06N7/00
Filed: 1963-04-29
Abstract: Foamed flexible plastic sheeting having a deeply embossed surface is made by sintering a thin layer of dry blended thermoplastic resin particles and a plasticizer, which contains in the blend a blowing agent, at a temperature exceeding the decomposition point of said blowing agent, followed by embossing the surface of the layer with a cooled embossing roll (see Division B6).  Suitable resins are vinyl chloride homopolymers, and copolymers with e.g. vinyl acetate and dialkyl maleates; a suitable blowing agent is azodicarbamide. Preferred particle size for the resin is about 15 microns; plasticizers mentioned include octyl benzoate, dioctyl phthalate, polyethylene glycol sebacate, and epoxidized soybean oil.  Other components that may be included in the dry blend of resin, plasticizer and blowing agent are: stabilizers such as barium stearate, cadmium stearate, or zinc octoate; fillers such as silica, or calcium carbonate; stearic acid; pigments; and fungicides.  The finished embossed sheet may optionally be coated with, e.g. acrylin or vinyl resins.

Title: Improvements in or relating to oscillating pumps and motors operating in parallel
IPC: F02B71/06
Filed: 1942-11-25
Abstract: 580,362. Speed governors. MUNTZ & CO., Ltd., A., and BEALE, E. S. L. Nov. 25, 1942, No. 16749. [Class 57] Reciprocating pumps or motors operating in parallel on a common main have means for maintaining a set phase relationship comprising a source 26A of pressure fluid, a flow interrupting device VM actuated by one of the pumps &c. M serving as master, and interrupting devices V<1>, V<2> actuated by the other, slave, pumps, the interrupters checking the flow periodically and the uninterrupted periods normally overlapping, and a controller 31<1> varying the periods of oscillation of the slave machines in response to the mean flow through the interrupted circuit to prevent departure from the set phase relationship. The reciprocating devices shown are fin-piston motor-compressors operated by combustion in the space 10 and returned by the pressure of air cushions in the ends of the cylinder 11, these cushions being connected to receive compressed air from or deliver it to the scavenging air space 15 through non-return valves 23, 24 under the control of valves 21<1> operated by the controller pistons 32<1>. The effect of change of loading, which alters the inner and outer dead centres and the phase relationship, is compensated by needle valves 36<1> controlling the areas of leak orifices 35<1> connected with the controllers 31<1>, and actuated by pistons supplied with pressure fluid under the control of the compressor pistons at their outer dead centres. The uninterrupted flow takes place at a dead centre. Alternatively, the flow may take place at an intermediate period, opening being limited to take place only in one direction of motion of the main pistons by sleeve valves 45, Fig. 5, which may be compensated for variations in load by connection at an intermediate point to a lever 50 connected at the ends of dead point followers. Two flow circuits may be used controlled by a single valve and associated with two controllers for each slave machine. An electrical system may replace the hydraulic system, the valves VM, V<1> being replaced by switches, the valves 45 by switches driven through friction couplings, the branch pipes by leads including resistances and unidirectional conductors, and the controllers 31<1> by solenoids or motors. Specification 579,734, [Group XXVII], is referred to.

Title: Improvements in or relating to pipeline pigs
Inventor: POWERS MARVIN DEWY
IPC: B08B9/04
Filed: 1970-04-08
Abstract: 1280102 Cleaning pipes M D POWERS 8 April 1970 [10 April 1969 19 Dec 1969] 16781/70 Heading F2N A gas propelled pig for removing liquids and debris from a pipe-line has at least two sealing members engaging the wall of a pipe-line to form an annular chamber, and has means for supplying pig-propelling gas to the annular chamber to expel at least a part of any liquid therefrom and eject it into the pipe-line downstream of the pig. As shown the pig is propelled by pressurized gas 116 and has sealing plugs 22, 24, 26, 28 forming chambers 60, 106, 110. The propellant gas 116 flows through the chambers 110, 106, 60 in series, entering the chambers 110, 106 through radial outlet tubes 122, 56 to atomize liquids remaining on the wall 12 of the pipe. The gas and absorbed liquids then pass through ports 59 into the front chamber 60, from which the fluids are syphoned out by a syphon line 64 and are discharged through nozzles 72 into the pipe-line downstream of the pig. The nozzles 72 are oriented to give a stirring effect to facilitate removal of solid debris. A valve 71 prevents fluids flowing from the downstream section 18 of the pipe-line into the syphon chamber 60. For applications where the liquid content of the pipe-line is low, only one or more atomization chambers need be provided and the syphon chamber can be omitted, and where drying requirements are not stringent only a syphon chamber need be provided. The sealing plugs may be formed by inflatable tyres, the pressure in which is selected to ensure that the pressure drop across the tyre is not greater than its internal pressure.
