Abstract: 954,254. Producing biaxially oriented films. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 11, 1962 [April 12, 1961 ; Dec. 22, 1961], Nos. 13192/61 and 46038/61. Drawings to Specification. Heading B5B. In the production of biaxially oriented linear organic thermoplastic tubular film by adjusting the temperature of a tube of the unoriented film material to a temperature below its melting point (defined as the temperature at which spherulites disappear using a hot stage polarizing microscope), at which temperature it can be uniformly expanded to biaxially orient it by internal gaseous pressure (with or without any additional stretch in the longitudinal direction), and expanding it and hauling off the resulting tubular film, the film is cooled by circumferentially uniformly applied draughts of air at least on the shoulder of the stretching tube so that a high internal gaseous pressure can be used to expand the tube and the tube is expanded by using a high internal gas pressure. The thermoplastic material may be a highly crystallizable linear polyolefine, such as polypropylene, and the tube may be cooled to a temperature before stretching such that the internal gaseous pressure is sufficiently high to give a hoop stress in the stretched film above 4000 p.s.i., and preferably above 5000 p.s.i. The thermoplastic material may be polypropylene and the tube may be cooled to a temperature before stretching it and the internal gas pressure may be such that the hoop stress in the tube just before it commences to stretch is at least 16.5 p.s.i. and preferably at least 20 p.s.i. The material may by highly crystallizable polythene and the temperature and internal gas pressure may be such that the hoop stress in the tube just before it commences to stretch is at least 8 p.s.i. and preferably at least 10.0 p.s.i. Transverse stretching may be made to commence before or at the same time as the longitudinal stretching commences by using a sufficiently high internal gas pressure. The film produced may be heat set. It may be further stretched in the longitudinal direction and thereafter heat set. The hoop stress in the stretched film Sd, is calculated from the diameter of the stretched film d and the pressure of. the film p, according to the formula S d =p.d/2t, where t is the thickness of the film. The hoop stress of the tube just before it commences to stretch, i.e. the hoop stress at the neck S n , is calculated according to the formula S n =p.d/2t(R f .R t <SP>2</SP>), in which R f  and R t  are the longitudinal and transverse stretch ratios, respectively.

Title: Process for producing white cast iron castings
IPC: C21C1/08
Filed: 1948-05-18
Abstract: In a process for controlling the physical properties of cast iron, a molten cast iron is produced having a constitutional carbide wedge value of 1 1/4 times white which is then processed to produce a processed carbide wedge value between 1 times white and 2 1/2 times white, the constitutional carbide wedge value being not greater than three times the maximum processed wedge value.  The carbide wedge value is obtained by breaking longitudinally a standard wedge-shaped casting and measuring the length of the line of demarcation between white and grey iron.  A casting of one inch square section which fractures just all white is called "one times white" and the phrase "times white" always refers to the appropriate thickness of the casting.  The line of demarcation in the constitutional wedge test may have a minimum length 1 3/8 times the average thickness of the casting to be made and in the processed wedge test a length between 1 1/8 and 2 3/4 times the average thickness of the casting.  For a 1 inch section casting, cast iron may be processed having a constitutional wedge value between 44/32 and 270/32 which is processed by the additional of a graphitizer to a processed wedge value of 36/32 to 90/32 and such a casting would fracture all white.

Abstract: 1340381 Automatic phase control INTERNATIONAL BUSINESS MACHINES CORP 7 May 1971 [18 June 1970] 13613/71 Heading H3A A control circuit for synchronizing an oscillator 1 with an input signal which undergoes zero transitions comprises means 3, 5 for sampling the input signal at two successive time instants, means 12, 13 for determining when a zero transition occurs, and means 8 for deriving an oscillator control signal from the sampled signal when a zero transition is sensed. At the first of two sampling instants, sample and hold circuit 3 stores a signal which is dependent on the instantaneous magnitude and polarity of the sampled signal. At the second sampling instant, bi-stable 5 is triggered and sets to a "1" or "0" state depending on the polarity of the input signal on line 4 at that instant. If the polarity is positive gate 6 is enabled to pass the signal from store 3 without polarity reversal. If on the other hand the polarity on line 4 is negative, then gate 6 is enabled to pass the signal from store 3 with polarity inversion. The output from bistable 5 is also applied to a "one bit" delay 12. If a zero transition occurs between two successive triggerings of bi-stable 5, the stored output from it and the new output differ, and EXCLUSIVE- OR 13 provides an output which opens gate 8. The output from gate 6 is then applied to an averaging circuit 9 to provide the control signal for oscillator 1. The gates 6, 8 may be differential input amplifiers, the inputs of which may be earthed by FET clamp circuits as required Figs. 4, 5 (not shown).

[Class 112.] Chain-stitching by barbed needles.-The needle movements are automatically varied according to the speed of the machine to avoid reeving or breaking the thread. The invention is specially applicable to the boot-sole sewing machine described in Specification 13873/10, [Class 112, Sewing &c.], which operates at different speeds according to whether the machine is sewing along sides or round the toe or heel. The needle 1 is carried by the usual carrier 3 swung round its pivot 5 by the arm 7 actuated by the member 11 pivoted on the shaft 15. The member 11 is actuated by a roller 19 travelling in a cam track 21 in the member 23 mounted on the main shaft. A weighted arm 39 is pivoted on the cam and is swung outwards centrifugally against the spring 33 when the main shaft exceeds a certain speed. This causes an arm 25, mounted on a stud on the arm 39, to overlay a portion of the cam track 21, as shown in Fig. 3, so diverting the roller 19 into a new path and automatically slowing down the needle in its withdrawal from the work and easing the thread tension. The feeding mechanism is the same as that described in Specifications 115,235, [Class 112, Sewing &c.]. The tension device is as described in Specification 28985/10, [Class 112, Sewing &c.].
