Title: Improved dispersion of pigments in polycarbonamides
IPC: C08K13/02
Filed: 1967-11-14
Abstract: 1,196,809. TiO 2  dispersion in polycarbonamides. MONSANTO CO. 14 Nov., 1967 [16 Nov., 1966], No. 51709/67. Heading C3R. [Also in Division Cl] A filament of a synthetic linear polycarbonamide contains at least 0À5%, based on the weight of the polycarbonamide, of a metal salt electrolyte and between 0À1 and 5À0%, based on the weight of the polycarbonamide, of a pigment comprising TiO 2  coated with aluminium oxide, the aluminium oxide constituting 2 to 15, preferably 2 to 10 wt. per cent of the pigment. Conventional di-acids and derivatives, diamine and derivatives, and amino acid reactants yielding the polycarbonamide are listed and aromatic alkali metal sulphonates, e.g. 3,5-disulpho-benzoic acid di-potassium salt, are the only metal salt electrolytes specified. The coating of aluminium oxide prevents agglomeration of the pigment which formerly occurred due to the presence of the metal salt electrolyte in the polycarbonamide. In examples, the coated pigment is introduced as an aqueous slurry during the hydrolytic polymerization of nylon 66 salt containing 1À5 wt. per cent of 3,5-disulphobenzoic acid dipotassium salt. Antioxidants, plasticizers and viscosity stabilizers may also be present.

Title: Light-tight film magazines
IPC: G03B21/32
Filed: 1970-10-30
Abstract: 1325749 Film magazines EASTMAN KODAK CO 30 Oct 1970 [30 Oct 1969] 51752/70 Heading G2A and G2C A film magazine in which a film spool 14 is rotatably mounted on a spindle 12 has means which can be moved into engagement with the spool for axially positioning it on the spindle and for imposing a frictional drag on the spool, and which means can be retracted out of engagement with the spool. The spool is formed of two flange members mounted on a hub Fig.4, (not shown), one of which flanges can be reversed so as to adapt the spool for films of two different widths. Two brackets 34 are pivotally mounted on shafts 36, and are urged by springs 38 into engagement with the spool 14. Each bracket carries, at the end opposite to the shaft 36, another shaft 32 on which is mounted three grooved rollers 30. When moved into engagement with the spool, two of these three rollers engage with the edges of the spool, according to which size of film the spool is set for. Thus the grooved rollers serve to position the spool on its spindle, and also to effect a frictional drag thereon. Another bracket 40, pivotally mounted on a shaft 42 at one end, is also spring-urged to bring its other end into contact with the spool. This end carries a sensing wheel 44 which, when in contact with spool 14, is rotated thereby. This rotation is transmitted by a belt 54 to a pulley 52 and hence to an indicator disc 56 mounted outside the magazine. It is intended that the film on spool 14 is to be passed from the magazine directly into a film processor, and the magazine can be attached by means as at 100, 102 to the top plate 101 of the processor. The film 15 passes out of the magazine through a light-lock formed by two arcuate plates 58 and 76. As seen in Fig. 1 the plate 76 is pivoted away from plate 58 into an open position. The closed and operative position is seen best in Fig.2 (not shown), the plates being pads of a suitable foam material. A cam plate 84 is rotatably mounted on wall 13 about spindle 12, and can be turned by a handle 90 to take up one of two positions under the action of an over-centre spring. The cam has surfaces which engage follower rollers on brackets 34 and 40 and light-lock plate 76. Thus rotating the cam in one direction moves all the brackets to the disengaged position and opens the light-lock. The film can now be loaded on to the spool in a dark room. Rotating the cam in the other direction engages all the brackets with the spool, and closes the light-lock. The magazine can now be carried into a lighted room and mounted on the processor.

Abstract: 1,269,467. Measuring yarn thickness electrically. S. PEYER. Oct.30, 1970 [Nov. 6, 1969], No.51807/70. Headings G1A and G1N. In apparatus for detecting faults in yarn wherein the yarn is fed through a measuring head 30 Fig. 3 to convert thickness into a corresponding voltage, the amplitude of the signal is automatically controlled to componensate for long term variations produced by drift, dust, &c. The thickness signal, after amplifications at 31, is compared at 37 with a reference signal 39, any difference energizing a motor 33 to vary an element 32 in amplifier 31 to adjust its gain and give a constant output voltage, with uniform yarn in head 30, which is also fed to control apparatus at terminal 35. A pulse in the output signal produced by a sudden change in the test yarn by-passes the AGC loop through capacitor 41, but is fed to the control apparatus at 35 to cut the yarn if the pulse exceeds a predetermined value. A switch 40 in the AGC loop is only closed when the test yarn is in motion.

Abstract: 1326578 Telegraphy WESTERN ELECTRIC CO Inc 19 Nov 1970 [20 Nov 1969] 54950/70 Heading H4P A transmission system for multilevel PCM signals over an analogue band-limited transmission medium using vestigial sideband modulation, comprises, at a transmitter, a transversal equalizer for predistorting multilevel PCM signals prior to their vestigial sideband modulation for transmission, and means for adjusting the equalizer to vary its distortion in response to control signals; and, at a receiver, control means responsive to digital signals derived from demodulated received signals for generating equalizer correction signals for transmission to the transmitter as control signals for the means for adjusting. Deriving equalizer correction signals at receiver (Fig. 3).-The received signals, after demodulation, are encoded at 17, i.e. sampled and digitized, to produce a data output, pulses Sgn(a k ) representing sample polarities which are fed to a shift register 61, and pulses Sgn(e k ) representing the signs of the errors introduced on digitization which are fed to a shift register 60. A counter 69 selects each location of register 61 in turn and supplies its contents to an EXCL-OR 72 for correlation with the output of register 60 for an interval of time defined by the set state of a bi-stable 74 reset on reaching a predetermined count at 65, the pulses produced from EXCL-OR 72 being counted in a counter 62 which is reset from 87 after each location of register 61. One or neither of two flip-flops 84, 85 is set according as the count is above a first predetermined value or below a second lower predetermined value or between them respectively, and correspondingly the sequence 10, 01 or 00 is sent over a reverse channel to the transmitter via an OR gate 95. A synchronization sequence 11 is also sent from an AND gate 94 via OR 95. Adjusting transversal equalizer at transmitter (Fig. 4, not shown).-The two-bit sequences from the reverse channel are decoded. The synchronization sequence results in incrementing of an address counter which addresses a memory to load a tap setting from it into a counter which is then incremented, decremented or left unchanged according to the sequences 10,01,00 received. The resulting count is stored in the memory, and also converted to analogue form and applied by a tap selection matrix controlled by the address counter to adjust the gain at the appropriate tap in the equalizer.
