Inventor: MATTHIES HANS GEORG DR
IPC: C08K3/36
Abstract: 1,054,329. Linear polyesters pigmented with TiO 2 . BADISCHE ANILIN- & SODAFABRIK A G. Oct. 29, 1963 [Nov. 3, 1962], No. 42557/62. Heading C3R. A process for the production of linear polyesters pigmented with TiO 2  comprises transesterifying an alkyl ester of a dicarboxylic acid with a glycol in the presence of a stabilized suspension of TiO 2 , and polycondensing the glycol ester, wherein the suspension stabilizer is an alumina sol of pH 4-6, a silicic acid sol of pH 7-9 or a polyphosphate sol of pH 6-8 -the pH being measured in 25% by weight solutions. The stabilizer sols are usually equal to 5-30% by weight of the TiO 2 , which itself is usually 0À3-2% by weight of the finished polyester. The suspension stabilizers may be pre-suspended in a glycol, e.g. ethylene, propylene or butylene glycols or cyclohexane dicarbinol, then added to a TiO 2  suspension, or both may be suspended together. Suitable starting materials for the polyester preparation are methyl, ethyl or butyl esters of isophthalic, adipic, vanillic, or, preferably terephthalic acid, and ethylene, propylene, or butylene glycols. In examples TiO 2  is added to make a 6% suspension in ethylene glycol containing 1% of an alumina sol of pH 4, or 1, 1À5 or 2% of a silicic acid sol of pH 8, or 1, 1À5 or 2% of a polyphosphate sol of pH 7, and the stability of these suspensions is shown. A polyester is prepared from dimethyl terephthalate, ethylene glycol, a 1% alumina or silicic acid sol, zinc borate and antimony trioxide.

Abstract: 1,054,756. Sulphur burners. METALLGESELLSCHAFT A.G. March 26, 1964 [March 27, 1963], No. 12982/64. Heading C1A. In a method for burning sulphur atomized liquid S is introduced into a combustion chamber by means of a truncated conical spinning cup. Liquid S is fed into the cup and is spun off its edges in the form of fine droplets which are carried into the furnace by primary air blown towards the combustion chamber along the edges of the cup. The liquid S may be fed into the spinning cup through ports in a hollow shaft which rotates with the cup. The primary air, at a temperature of 20‹ to 300‹ C., may be blown towards the combustion chamber by an impeller. The process may be carried out in the apparatus of Fig. 1, in which liquid S is fed into pipe 1 with substantially no pressure and is introduced into the spinning cup 5 through ports 10 located in the rotating hollow shaft 4. S is spun off in the form of fine droplets at the periphery 6 of the cup which projects slightly beyond the annular channel 7 into the combustion chamber. Primary air, introduced at 8 and carried into channel 7 by impeller 9 carries the droplets into the combustion chamber and causes further disintegration.

Abstract: 1,054,946. Reticular films. O-B. RASMUSSEN. Sept. 2, 1963 [Sept. 7, 1962], No. 34607/63. Heading B5B. [Also in Division D1] A reticular film is derived from an oriented film of thermo-plastic material by partial splitting, has a net-like structure and comprises linear parallel stem fibres having the direction of orientation extending in a straight line along their length, and thin short branch fibres parallel to one another interconnecting adjacent stem fibres, each stem fibre side being slightly displaced transverse to the direction of orientation at each junction with a branch fibre, as a result of the branch fibres interconnecting the adjacent sides of adjacent stem fibres having been torn out from these sides (Fig. 1, not shown). The film may further comprise " third order " fibres each interconnecting a pair of adjacent branch fibres and parallel to the stem fibres. The film may be produced by compressively sandwiching an oriented film between two bands of elastic material and stretching the bands and the film at an oblique angle to the direction of orientation. The reticular film thus produced may be further stretched between two bands of elastic material in a direction parallel to the branch fibres of the reticular film to form a reticular film comprising " third order " fibres. The reticular film may be produced in a continuous manner by compressively sandwiching a continuous length of a longitudinally oriented film between the operative runs of two endless travelling bands of elastic material, passing the sandwich under pressure through the nip of a pair of nip rolls arranged at an oblique angle to the direction of travel of the bands and stretching the sandwich at right angles to the nip and thereafter releasing the film from between the bands. The reticular films of the invention are well suited for use as an unwoven textile material. a suitable number of layers being combined, for example by spot welding, until the product has the desired thickness.

Abstract: 1,228,001. Electro-physical measurement. INDUSTRIAL NUCLEONICS CORP. April 1, 1968 April 12, 1967], No. 15650/68. Heading G1N. [Also in Division G3] A gauge, producing a signal dependent on a property of travelling sheet material which varies periodically along its length, is scanned across the sheet at a velocity dependent on the longitudinal velocity of the sheet so that the effects of the variations are eliminated from the averaged output of the gauge. In Fig. 1, the thickness of a sheet 122 leaving a plastic extruder 124 is measured by a gauge 120 which is scanned across the sheet by a motor 156 the speed of which is controlled by a computer 148 to be inversely proportional to the longitudinal velocity of the sheet measured at 145 and directly proportional to the width of the sheet measured at 150 or the widths of zones L, C and R determined by limit switches 174. Signals from gauge 120 are integrated and averaged at 140 for periods corresponding to the zones scanned and the arrangement is such that periodic variations of thickness caused by the extruder are averaged out. The averages are recorded at 166 and compared at 170 with a desired thickness so that any errors control the extruder drive at 130 and appropriate die lip adjusters 126-128 to correct the thickness in the appropriate zones. Application to a paper machine is referred to.

Abstract: 1,229,185. Thermal switches. THERM-0- DISC Inc. 24 July, 1969 [29 Nov., 1968], No. 37286/69. Heading H1N. In a thermostat operable by a bimetallic disc 137, Fig. 7, which moves a plunger 134 engageable after lost-motion with a movable contact strip 133, the plunger 134 is held in contact with the disc by an adjustable spring 142 whereby the "temperature/disc displacement" curve on rising temperature follows curves such as 151, Fig. 8, for a minimum temperature range or 161 for the maximum temperature range. Screw 146 adjusting the spring 142 therefore causes the switch to snap upwards from points 156 to 157 (minimum setting) or from points 163-164 (maximum setting). Contact arm 133 is also loaded by a separate differential setting spring 147 with an adjusting screw 148 whereby the restoring force on the disc 137 is increased so that it snaps back on the curves 152 or 162 at points 153 or 166. The temperature differential is therefore less than that with the spring 147 removed when the system would snap back from the left-hand peaks of the curves 151 or 161. The lost motion of plunger 134 assists in breaking a contact weld and, in the example, a backing contact leaf-spring 128 lifts up from a rigid stop support 131 so that on the return movement its impact with the support 131 assists in breaking the contact weld. In modifications the plunger 134 may be elongated and mounted within an elongated body, Fig. 1 (not shown), and engages an intermediate bumper (42) of plastics material. The backing contact 128 may also be omitted.

The support 6 includes a frame on which is slidable the headstock 1 carrying the arbor 7 within a housing 7A by bearings 8, 9, 10 and 11. A drive shaft splined connection nut 12 mounted within the arbor receives the drive shaft 2 and allows rotation of the arbor and axial movement relative to the shaft 2. The cylinder 3c of the device 3 is secured to the frame and is disposed about the shaft 2 which passed through a hollow pistonrod 3a carrying a piston 3b, the piston-rod 3a projecting through the cylinder and being rigidly connected to the headstock. A motor coupling 4 secured to the frame supports the upper end of the drive-shaft and couples this end to an hydraulic motor 5, of fixed or variable displacement. A girder to which studs are to be friction welded supports the welding apparatus, a fixture in which the apparatus is secured being clamped to the girder and wheels or rollers being provided on the fixture to facilitate its movement. A pump which supplies fluid both for the motor 5 and for the piston-cylinder device charges an accumulator before welding commences and valves permit the headstock 1 to move rapidly to bring the stud adjacent the work. When the stud meets the work the fluid flow to the cylinder is initially reduced to control the pressure build-up during welding. The apparatus may be supported from a jib 40, Fig. 4, carried on a motor vehicle 41, the lower end of the guides having members 42 to engage beneath the flanges of a girder. In one other embodiment three devices similar to those of Fig. 1 but wherein the frame top is connected to a flange on the device 3 are mounted together to weld rows of studs to a plate and in another, one such device is used to weld studs to a beam. The apparatus may be operated in oil or water.

Abstract: 1,256,470. Testing cigarettes. R. J. REYNOLDS TOBACCO CO. 28 Aug., 1970 [10 Sept., 1969], No. 41422/70. Heading A2C.  In an apparatus for inspecting the ends of cigarettes, the cigarettes 1 are conveyed in individual holders through a station where the ends of the cigarettes 1 are inspected for defects by a probe 23 mounted on one end of a pneumatically actuated piston 21. The cigarettes 1 are fed from a drum 2, between guide rails 3, and into individual holders comprising matching grooves 20 formed in two annular flanges 19a, 19b of a rotating inspection drum 4. The drum 4 carries the cigarettes 1 through an inspection zone A and thence onto a conveyer chain 5. The drum 4 includes a plurality of chambers 22 each having an opening adjacent the end of a cigarette 1 held in an individual holder, and each housing a piston 21. In the inspection zone A, a predetermined pneumatic pressure is applied from a source 28, via a chamber 16 in a stationary ring 11 and a port 10a in a bearing ring 10, to end 22b of the chamber 22 so as to act on the face of the piston 21 and move it to the left until the probe 23 engages the near end of the cigarette 1 in the respective holder, the left end of the cigarette 1 having been aligned by a guide rail 24. Where the cigarette 1 has a texturally loose end, the probe 23 will penetrate the end and cause the piston 21 to move further to the left than it would with a normal cigarette and so uncover a slot 25. The uncovering of this slot in the chamber 22 allows the testing air to pass therefrom, via a passage 9c, and port 10c and a chamber 17, to a memory system 27. Following inspection, the end 22a of the chamber 22 is vented to atmosphere by connection to a chamber 18a and pneumatic pressure is applied to the other end of the chamber 22, via passages 9a, 9b, a port 10b and a chamber 18, to return the piston 21 to its original position. The memory system 27 (Figs. 3, 4 not shown) which includes a rejection system, comprises; a plurality of pneumatic indicator valves (39) contained in chambers (38) in a rotatable memory drum (30) and corresponding in number to the inspecting pistons 21; each valve (39) being displaceable by the release of testing air by its corresponding inspecting piston 21 on detection of a defective cigarette, and the valves (39) allowing in their displaced position, after a further predetermined rotation of the drum (30), a reject air pressure to be applied to a nozzle (48) to reject the corresponding defective cigarette when it reaches a preset position during its travel on the conveyer chain 5. The displaced valves (39) are subsequently pneumatically returned to their original positions. The memory drum (30) may form part of the inspection drum 4, or may be a separate drum rotating in synchronism with the drum 4.

Abstract: 1,264,335. Self-processing transparency units. EASTMAN KODAK CO. Sept.27, 1968 [Oct.16, 1967], No.45962/68. Heading G2A. A transparency 11 is supported in a mount 10, and two rupturable pods 17, 18 holding processing fluid are mounted adjacent the transparency, the pods being arranged to exude the fluids on to the transparency after exposure thereof. A strippable sheet 13 adheres across one face of the mount. The unit is intended for developing inside a camera, after exposure of the film 11 through the aperture in mount 10 on the opposite side to sheet 13. Pod 17, which contains a developing agent, is ruptured first, and the contents squeezed out into the space 22 between the transparency and the sheet. Pod 18, which contains a fixing agent, is then ruptured and the contents squeezed through the empty pod 17 into space 22 to complete the processing of the film transparency. The mount is removed from the camera, and the sheet 13 stripped off, Fig. 6. The end 14 of the sheet may extend round the end of the mount, with its edge slightly bent away, as shown, so that it can be easily grasped. Alternatively, the end 14 of the sheet may be attached to a separate tab, Fig. 12 (not shown), or to a tab which is an integral part of mount 10 but which can be readily broken away, Fig. 10 (not shown). An advantage of the last two modifications is that the overall length of the mount can be reduced.
