Title: Polyurethane polymers
IPC: C08K3/34
Filed: 1961-07-05
Abstract: The invention comprises a polyurethane polymer containing as a filler a partially or fully calcined clay.  These clays have been heated above 500 DEG  C. and decomposed by evolution of water of constitution and are considered fully calcined if substantially all the water is lost and partially calcined if only a portion, i.e. 1/3 or more, of the water is lost. When ground, they usually have a particle size of 1 to 2.5 microns.  In examples reticulated solid elastomers were prepared from 40-50% clay, 49-59% polypropylene glycol (a 50:50 mixture of 1025 and 2025 molecular fractions) and 1% lead octoate (by weight) reacted with an adduct of 91% tolylene diisocyanate and 9% trimethylol propane. Tensile strengths and hardness of products from fully calcined, partially calcined and uncalcined clays are given.  Alkali resistance of products obtained similarly using dibutyl tin dilaurate catalyst is also determined. Polyesters and polyamides are other suitable starting materials.

Title: Method and apparatus for producing unsaturated hydrocarbons by an incomplete combustion of saturated hydrocarbons
Inventor: HESKY HANS
IPC: C07C2/78
Filed: 1959-07-18
Abstract: <PICT:0865601/IV (b)/1> <PICT:0865601/IV (b)/2> In the incomplete combustion of saturated hydrocarbons to form unsaturated hydrocarbons, e.g. in the conversion of methane to acetylene, the occurrence of a flame in the mixing chamber is prevented by injecting an additional gas (which prevents reaction of the reactants) into the area where the gas streams meet, whereby diffusion is prevented in the vicinity of the inlets.  In Fig. 1, oxygen enters by pipe 5 and methane through holes 2. Normally the velocity distribution at the plane 13, where diffusion begins, is as indicated by dotted line 12. At the low velocity at the edge of the pipe 5, combustion is likely to occur. By injecting a gas through the annular pipe 14, the velocity distribution becomes, as indicated by dotted line 15, and diffusion only begins to occur at plane 16 when the velocity throughout is sufficient for combustion not to occur.  The mixed gases are burned at 7 and quenched by water jets 9.  In an alternative arrangement (Fig. 2), the gases impinge at an angle and the other gas is injected by pipe 21 having its opening 20 in the angle, so that the point where diffusion begins is moved to point 22. The injected gas may be cold oxygen, cold methane or nitrogen.

Abstract: 1,263,785. Television. MARCONI CO. Ltd. 15 May, 1969, No. 24892/69. Addition to 1,238,467. Heading H4F. A television system of the type disclosed in the main patent 1,238,467 in which a plurality of optical images are projected on to a single camera tube and corresponding points, lines, or fields of the images are scanned in turn, is modified by causing the scanning beam to wobble so that a plurality of lines of each image are scanned at each pass. As shown, Fig. 1, red, green and blue images are projected one above the other on to the face of an image orthicon camera tube 5. A 30MHz chopping waveform is applied to the gun of the camera tube, and the normal deflection waveforms are supplemented by a three-level field shift waveform from source 7 so that for successive sampling pulses the beam is directed to corresponding points of the three images in turn. A wobble voltage is also superimposed on these field scanning and shift waveforms so that for each sampling of a particular image three adjacent lines are scanned a number of times. The wobble voltage waveform comprises a three-level staircase having a period H. The output of the camera tube is applied to three detectors 10, 12, 14 via delay lines 11, 13. The detectors are synchronized by the wobble voltage and their outputs are fed to synchronous distributer switches 15, 16, 17 driven by the shift voltage to provide spot sequential signals on the red, green and blue output lines.

Abstract: 989,869. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 24, 1963 [June 27, 1962], No. 24958/63. Heading B6F. Machines with types upon spherical heads; type-actions using auxiliary power.-A typewriter having a tiltable and rotatable print head 101, Fig. 1, having a plurality of characters of a type fount embossed thereon includes a print impression mechanism characterized in that the print head is movable to a printing position at a velocity determined by a particular key 106 selected. Upon depression of the key 106 a pawl 119 mounted thereon displaces an interposer 121 downwardly to depress a bail 125 by a lug 124 which pivots a latch 114 to release a clutch sleeve 113 of a clutch 112 to cause rotation of a printing cycle shaft 111 through 180 degrees. The shaft 111 through gears 127, 128, 129 causes a 180 degree rotation of a snatch roll 130, which engages a step 132 on the depressed interposer 121 to force it forwardly to operate a character selector mechanism so as to rotate and tilt the head 101, through selector bails, a tape and pulley mechanism (not shown). Impression arrangements.-To vary the impression force of the type head for characters having a large impression area and special marks having a small impression area, e.g. a full stop or a comma, the rocker 102, Fig. 2, on which the type head 101 is mounted is driven by means of a high velocity cam 232 or low velocity cam 231. Depression of a key 106 for a large impression area character results in forward displacement of the interposer 121 only, which enters a slot 203 of a vane 202 and the rocker 102 is rocked for impression by the high velocity cam 232 driven through a shaft 230 and engaging a cam follower 235 mounted slidably in an arm 237 pivoting about 238. Depression of a key 106 corresponding to a small impression area character displaces forwardly an additional interposer 201, which engages a projection 205 of the vane 202 to rock a bell-crank lever 209 anticlockwise and release a cam follower 212 whose upper extension 215 is able to drop off the lobe 216 of cam 217. The lower extension 218 of the follower 212 draws a cable 219 enclosed in a sheath 221 forwardly to pivot an arm 223 anti-clockwise, which engages a collar 225 of a sleeve 226 having mounted thereon the cam follower 235 so as to displace it to the left and align it with the lower velocity cam 231. In another embodiment (not shown) high velocity printing action may be imparted through by movement of the vane 202, cable 219 and follower 235. In a further embodiment (not shown) the interposer 201 may be provided with ends of different lengths for engagement with projections 205 thereby imparting varying angular displacements to the vane 202 and lever 209 for engagement with one of a plurality of impression control cams.
