Title: Method for treating sheets of polymeric olefines for deep drawing
IPC: B29C51/00
Filed: 1959-12-07
Abstract: A polyolefin film that has previously undergone longitudinal orientation is stretched, at a temperature with the elastic range between the freezing point and the crystallite melting point of the polyolefin, in a transverse direction until the sheet appears substantially isotropic in polarized light.  Polyolefins used are derived from monomers of the general formula CH2=CHR in which R represents a hydrogen atom or a straight chain or branched hydrocarbon radical containing 1-12 carbon atoms, especially low pressure polyethylene, polypropylene, and copolymers of ethylene and propylene, and mixtures of polyethylene and polypropylene. The specified temperature range for low pressure polyethylene is from about -100 DEG  to 130 DEG C., and for polypropylene from about -40 DEG  to 180 DEG C.  Advantageously, transverse stretching is carried out on a hot film, immediately followings its manufacture at 40 DEG to 110 DEG C., especially 80 DEG -95 DEG C., to 103-120% of the original width of the film.  Film so treated may be deepdrawn without wrinkling. Specifications 799,392, 799,823, 801,031, 862,639, 935,285 and French Specification 1,197,427 are referred to.

Abstract: 1448576 Controlling vehicles on merging track MESSERSCHMITT-BOLKOW-BLOHM GmbH 5 Sept 1973 [6 Sept 1972] 41820/73 Heading B7N In a control arrangement for merging vehicles 1, 2 on tracks 3, 4 into a common stream on track 6 and in which each vehicle carries a transmitter 7, which transmits to its rear via a signal attenuating line 9 a signal having an amplitude which is an inverse function of its speed and a receiver 8 having a sensitivity proportional to its speed which is coupled to the line and derives an output signal from a vehicle in advance by which the spacing between vehicles is controlled, each line 9 is regularly cross-connected to a similar line 10 associated with the other track and each vehicle carries a receiver 8<SP>1</SP> coupled to the line 10 and is controlled to act as if the track on which it runs carries its existing traffic plus an image of the traffic on the other line and by adjusting its position in this composite stream ensures merging without collision at junction 5. Units 21, 211 on the vehicles ensure that they transmit only to the rear. The regular cross connections can be direct links spaced a few centimetres apart, Fig. 4 (not shown), or can be links with amplifiers 22 spaced apart by a distance equal to the minimum distance between vehicle centres. Forward transmission of the signal in the line 10 is limited by also feeding the next ahead amplifier in opposite phase via a unit 23 which simulates the line loss between amplifiers. The lines 10 can be segmented with the segment end further from the junction terminated with the line characteristic impedance and the line 9 is connected to the other end via an amplifier 25 and transmitter 26, which reproduces the signal applied from line 9. Attenuators 31 can be provided which increase in value with distance from the junction and act to prevent sudden change in vehicle position. Vehicle detectors 27 can be provided adjacent each cross connection point and are coupled in a logic circuit, Fig. 8 (not shown), whereby one of two vehicles equally spaced from the junction is given right of way.

Abstract: 1276822 Preparing solid aliphatic amino di(alkylene phosphonic acids) MONSANTO CO 4 Sept 1970 42483/70 Heading C2P A solid aliphatic amino di(alkylene phosphonic acid) is obtained from a crude liquid reaction product obtained by reacting together a primary amine, an aldehyde or ketone, and orthophosphorous acid by containing the said reaction product in liquid form with at least intermittent agitation, with at least twice its weight of a liquid diluent maintained at a temperature of at least just above the freezing point of the reaction product, thereby forming a slurry in the liquid phase of a solid phase containing the said amino di(alkylene phosphonic acid), heating the slurry to from 80‹ to 100‹ C., maintaining it at that temperature for at least one minute, and separating the solid phase from the slurry. Specified liquid diluents are water, methanol, ethanol, n or iso-propanol, acetone and methyl ethyl ketone. If desired the liquid slurry may be cooled, e.g. to 70‹ C. or lower, e.g. 20‹ C., before separation of the solid phase which may be effected by filtration or centrifugation. The liquid slurry before separation of the solid phase may be admixed with an aqueous solution containing an alkali metal hydroxide to form the alkali metal salt of the phosphonic acid in solution and the latter may then be contacted with activated carbon to remove colour-forming impurities. The activated carbon is then separated from the purified salt solution and the solution then treated with a mineral acid to convert the salt to the free acid. The activated carbon may be contacted with the salt solution in either a batch-wise or continuous manner and may be in powder.or granular form.

IPC: G06C23/00
Abstract: 427,413. Clutches. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and BROOME, J. H., 80, Leyland Road, Lee, both in London. Oct. 21, 1933, No. 29200. [Class 80 (ii)] The driven member 3 pivotally carries one or more pawls 5 co-operating with a driving ratchet wheel 2, and an annulus 11 loosely carried by the member 3 is connected to the latter by a spring 18, the pawl 5 having a slot engaged by a pin 19 on the annulus. An electromagnetically controlled stop lever 13 co-operates with any one of a number of abutments 12 on the annulus. On moving the lever 13 from the abutment 12, the annulus moves forward under the action of the spring 18 and the pawl is brought into engagement with the ratchet wheel. On releasing the lever so that it engages with the first abutment which it encounters, the member 3 continues to rotate, stressing the spring 18, until the pawl disengages and an abutment 20 on the member 3 comes against a pin on the annulus, when the member 3 is stopped. Reverse rotation of the member 3 is prevented by a detent 7. Where a number of pawls are used, the spacing of them may differ from that of the ratchet teeth, so that the first to engage takes the drive. In this case, the pawls are spring-loaded and clearance is provided for the pins 19.

Abstract: 1484993 Distorted images DEFENCE SECRETARY OF STATE FOR 19 Nov 1974 [13 Sept 1973] 43009/73 Heading G2X [Also in Division H1] In the method of manufacture of an electronic micro circuit that includes the steps of preparing a master layout, producing by a photographic process at least one master mask from the master layout and projecting on to a semi-conductor chip coated with a film of photo-sensitive emulsion an image of the master mask, a variant of a basic electronic micro circuit is manufactured by a process that includes the step of optically producing distortion of at least part of the image of the master layout or of the master masks produced from it so as to modify in the variant the electrical value of at least one component as compared with its value in the basic micro circuit. The image of the master layout can be distorted in two predetermined directions e.g. using an anamorphic lens. Standard reproduction camera systems as used in the printing industry that provide for distortion e.g. increase or decrease parallel to x or y axis can also be used. In an example a resistor, incorporated in a semi-conductor chip is made by diffusion of p-type impurities into the resistor body 29 of an n-type epitaxial layer 21, isolated from the rest of the circuit by regions 26 and 27 of p-type material. Contacts 30 and 31 are provided. If a first resistor has the dimensions given in Fig. 6 a second resistor of different value is obtained, Fig. 7, by using master masks obtained by optical distortion from the drawing master mask of the micro circuit containing the first resistor.

The formation in the vicinity of a well penetrating the formation is consolidated by placing an unsaturated fatty acid material in the formation adjacent the well and thereafter passing an oxygen-containing gas into the formation from the well, the reaction being controlled to prevent ignition of the unsaturated fatty acid material. The unsaturated fatty material includes the fatty acid, its salts, its esters and mixtures thereof, and may be an oil containing oleic, linoleic or linolenic acid or mixtures of these acids together with saturated fatty acids. The material, in solution if necessary, is injected through a tube in the well into the whole or part of the depth of the formation, the formation having been previously cleaned by means of a suitable fluid. The gas may be air, and if the same tube is used for the material and the air an inert fluid such as nitrogen is passed through the tube between the material and gas injections. The rate of supply of the air, which may be cooled to avoid ignition, is found experimentally and air is supplied at below this rate, or at above this rate but the supply being terminated before the ignition temperature is reached. The solidification of the material may be accelerated by means of a catalyst or by heating.
