Abstract: 967,127. Stretching films. J. C. NASH. Dec. 12, 1962 [Oct. 15, 1962], No. 46857/62. Heading B5B. A longitudinal web stretching machine has opposed frame walls 11, 12, interconnecting longitudinal members 15, 16 between said walls, two sets of draw rolls 51, 52 and 53, 54 over which the web " F " to be stretched passes, support means for the set of rolls 51, 52 carried by the frame, adjustable support means (sliding panels 45, 46), carried by the frame for the set of rolls 53, 54, for varying the distance " S " between said two sets of rolls and means for positively rotating each set of rolls independently of the other and at different relative speeds (motor 30, variable speed mechanism 29 and the belt drive and gearing system shown). Rolls 51, 52 may be heated, and rolls 53, 54 cooled (or heated if required) by the circulation of a heat transfer fluid through the rolls in known manner, and the web may be additionally heated by a radiant heater 200. The sliding panels are actuated by a rack-and-pinion mechanism 161, 162, and may be locked in any desired position. Slippage of the web on the rolls is prevented by pinch rolls 64, pivotally mounted on the two opposed walls 11, 12, which, actuated by hydraulic cylinder 76 via bell-crank lever 72 urges the web against roll 52, and pinch rolls 144, pivotally mounted on the sliding panels 45, 46, which, actuated by hydraulic oylinder 156 via bell-crank lever 152 urges the web against roll 54. The sliding panel mechanism enables the stretch ratio of the film to be varied by variation of the distance between the two sets of draw rolls, independently of the rate of stretch which can be varied by variation in the speed of rotation of the two sets of draw rolls. U.S.A. Specifications 1,651,502, 2,469,653 and 2,498,662 are referred to.

Title: Improvements in or relating to pulse modulation encoders and decoders
IPC: H03M1/00
Filed: 1962-12-18
Abstract: 1,023,448. Electric selective signalling systems. WESTERN ELECTRIC CO. Inc. Dec. 18, 1962 [Dec. 29, 1961], No. 47669/62. Heading G4H. A P.C.M. system in which coding is effected by the sequential comparison of a message sample with reference currents from weighted network, is characterized in that a biasing current is supplied to the comparison network to compensate for the error signal introduced therein by the electronic switches in the reference current network For encoding each message sample a timing circuit 56, Fig. 1, delivers clock pulses D1, D2 . . . DN over lines 58, 60, 62. During each clock pulse the message sample is from circuit 68 is compared with a reference current i r  derived from the weighted network 64, by a comparator 40 whose output at 42 is a binary " 1 " if is + i r  is positive and " 0 " if this sum is negative. At the first clock pulse D1 all the switches 86, 88, 90 &c. in the weighted network 64 are closed, i.e. ir is zero, so that the first code output pulse at 42 is a binary 1 or zero according to whether the message sample is positive or negative and thus indicates the polarity of the sample. If the message sample is positive the output at 42 is fed back to operate an AND gate 50 which reverses (for the duration of the sample), the polarity of the source E r  feeding the network 64, so that during subsequent comparisons ir will be of opposite sense to is. During clock pulses D2 ... DN the reference current i r  is weighted in known manner by selected operation of the switches 86, 88 &c. by the reference control circuit 44 under control of the clock pulses and the P.C.M. output pulses fed back over line 70. During the encoding of low-level message samples the majority of the switches 86, 88 etc. in circuit 64 are kept closed and due to contact potentials a spurious current i g  flows to comparison point 54. In order to counteract this effect the value of a biasing current i x  is switched from one value to another according to the polarity of the meassage sample by a correction circuit 92. The biasing current i x . Fig. 2, is obtained from the reference voltage supply E, via transistors Q1 and Q2. Transistor Q2 is always conductive but transistor Q 1 is switched " on " when E r  is positive and " off " when E r  is a negative, resulting in a decrease in i x  during positive E r , i.e. when i g  is positive and an increase in i x  during negative E r , i.e. when ig   is negative. These changes in i x  are made equal to the maximal value of i g , i.e. when all switches in circuit 64 are closed.
