Title: Continuous mass polymerization process
IPC: C08F2/02
Filed: 1972-08-15
Abstract: 1359247 Polymerisation apparatus; mixing apparatus MONSANTO CO 15 Aug 1972 [16 Aug 1971 (2) 25 May 1972] 38034/72 Headings B1C and B1X [Also in Division C3] The invention comprises a continuous mass polymerisation process characterised by being carried out under specific mixing/reaction conditions. Figures 4 and 5 depict an experimental apparatus used to demonstrate such a process. The mixer/reactor comprises a glass cylinder 70 (which is interchangeable with a jacketed steel cylinder, not shown, for heating or cooling). Either cylinder has a glass end plate 71 for viewing of the mixing process, and the assembly is held together by clamp rings 75 and tie rods 76. The cylinder is supported in ball bearings 73 and has a torquemeasuring arm 74. The cylinder has a rotatable paddle assembly disposed therein, which almost touches the inner surface of the cylinder. This assembly is described in more detail in Fig. 5. The paddle is essentially an S-shaped impeller having adjustable edges 78 to vary the clearance with the cylinder wall. The blade-tip inclination angles 79 and 80 are different so that the effect of changing the direction of rotation, and amount of fillage can be investigated. The various mixing forces imposed on the viscous reaction mixture are described in great detail, the most important ones being that the mass is subjected to a 'rolling' action in the nip between the impeller blade tip and the cylinder wall, and the fact that the mixture is caused to move from one end of the cylinder to the other and back, owing to a pressure gradient built up along the edge of the blades. Removable openings 81 in the blades permit investigation of this phenomenon. - The cylinder is also provided with a feed screw for the reactants. The reactor may be discharged continuously from the bottom of the cylinder by a pump (30p, Fig. 1 not shown).

A method of producing a tool for grinding profiled sections, such strips made of wood, synthetic material or the like comprises coating a pattern of the profile to be ground with abrasive particles, rotating a grinding tool blank having at least the surface thereof of a material having an abrasive resistance less than that of the particles relative to and in contact with the particles to form a counter profile on the blank, and applying a coating of abrasive particles to the tool in the region of the counter profile. As described, a pattern 1, Fig. 3, is provided with a profile 2 on to which is sprayed a water-soluble adhesive 3. Abrasive particles 4 are sprinkled on to the adhesive and a rotating blank 5, Fig. 4, is moved radially towards and along the pattern so as to be formed with a profile counter to that of the pattern, the blank being of synthetic material such as foamed polystyrol. The profiled blank is coated with water-soluble adhesive 3a, Fig. 6, and abrasive particles 4a and is then used to grind a workpiece 1a to the same profile as the pattern 1. When the abrasive particles have become dull from use, they can be removed from the pattern and tool by dissolving the adhesive and the pattern and tool are then re-coated. When large amounts of material are to be removed. the grinding may be effected in steps using a number of tools having successively finer abrasive. Several tools may also be arranged around the periphery of the workpiece. The tools may be of the rotary or reciprocating type.

Abstract: 1481414 Radar EMI Ltd 5 Aug 1974 [21 Aug 1973] 39649/73 Heading H4D A sideways looking synthetic aperture radar, receiving echoes from static and moving targets with Doppler frequencies as shown in Fig. 3, is made to respond to moving targets only by having an aerial 1, Fig. 8, enabling consecutive pulses to be transmitted from the same position relative to the ground (e.g. with the aircraft moving to the left the first pulse is radiated from elements 3, 4 and the second from elements 4, 5) such that subtraction (10, 11) of the Doppler returns cancels out the static target signals. The remaining signals due to the moving targets have component frequencies grouped in pairs spaced by the Doppler shifts about multiples nf s  of the repetition frequency f s . The Doppler shift may be greater than f s , but "fold-over" or "aliasing" causes the components to always have at least an "alias" component within the range (f s /2 -fd max )-...(f s /2+fd max ) Fig. 4, of a standard correlator 18. The transmitter/ receiver 2 produces in-phase and quadrature signals to enable the phase of the Doppler signals to be indicated. The subtraction of consecutive echo signals causes "blind speeds", but again, the "aliasing" phenomena puts a component outside the influence of such a "blind speed". Four consecutive returns a, b, c, d, may be combined as (a-b)-(c-d) Fig. 9 (not shown). This reduces by half the amount of data which has to be processed in any scan.
