Title: Process for rendering high-molecular weight organic polymers resistant to electrostatic charge
IPC: C07F9/24
Filed: 1965-09-27
Abstract: Macromolecular organic compounds are rendered resistant to electrostatic charge by incorporating 0.1 to 7 weight per cent based on the compound of a polymer of an N,N-dialkyl phosphoric acid amide in which the phosphorus atoms are chemically bonded to oxygen or nitrogen atoms, the ratio of P:N is in the range 1:1 to 1:2 and the N,N-dialkylamide groups have the formula -NR1R2, where R1 is a C1- 4 alkyl and R2 is C10- 26 alkyl. The phosphoric acid amide polymers may contain from 2 to more than 20 units, and may be cyclic or linear. They may be prepared by reacting 1 mol. of phosphorus pentoxide with 2 to 4 mols. of N,N-dialkyl amine, optionally together with ammonia, an amine or an alcohol. Specified macromolecular compounds are polymers of butadiene, vinyl acetate, olefins, styrene, acrylic and methacrylic esters and nitriles, vinyl chloride and vinyl carbazole; and polyvinyl acetals, polyoxymethylenes, polyesters, e.g. polyterephthalates and polycarbonates, polyamides, polyurethanes and cellulose derivatives. The compositions may be fabricated into shaped articles.  Examples describe compositions comprising condensates of 0.8 mol. phosphorus pentoxide with 2 mols. of N-methylstearylamine and (5) polyethylene and (6) polystyrene; condensates of 0.8 mol. phosphorus pentoxide with 1 mol. methylstearylamine and 1 mol. methylhexadecylamine and (1) polyethylene, (3) polyacetal resin and (4) a butadiene/styrene copolymer; a condensate of 0.5 mol. phosphorus pentoxide with 2 mols. methylstearylamine and (7) polyvinyl acetate; and polypropylene with (2) a condensate of 1.6 mols. phosphorus pentoxide with 4 mols. methyldodecylamine; (8) diphosphoric acid-di-N-methylstearylamide; (9) di(phosphoric acid-N-methylstearylamide) imide and (10) tetraphosphoric acid tetramethylstearylamide.ALSO:Polymers of N,N-dialkyl phosphoric acid amides in which the P atoms are bonded to each other through O or N, the ratio P:N is 1:1 to 1:2 and the N,N-dialkyl amide groups have the formula -NR1R2 where R1 is C1- 4 alkyl and R2 is C10- 26 alkyl, may be prepared by reacting 1 mole of phosphorus pentoxide or metaphosphoric acid with 2 to 4 moles of a dialkylamine, optionally together with further reaction, e.g. with ammonia, an amine or an alcohol.  The polymers may be linear or cyclic.  In examples products are obtained by reacting in the specified molar proportions (A) 0.8 phosphorus pentoxide and 2 N-methyl-stearylamine, (B) 0.8 phosphorus pentoxide and 2 of a mixture of methylstearylamine and methylhexadecylamine, (C) 1.6 phosphorus pentoxide and 4 methyldodecylamine and (D) 0.5 phosphorus pentoxide and 2 methylstearylamine.

Title: Method of recording television video information
Inventor: WESSELS J
IPC: H04N9/83
Filed: 1973-08-31
Abstract: 1433904 Recording television signals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 31 Aug 1973 [2 Sept 1972] 41116/73 Heading H4F In a colour television signal recording system, the original luminance signal E Y ', Fig. 4, and colour signal modulated sub-carrier E' C  are separated by filters 1 and the luminance signal frequency modulated at 2 on to, e.g. a 3À5 MHz carrier and the colour signal &c. frequency shifted to below the resulting f.m. signal by means of a mixer 5 and "multiple of line frequency" oscillator 6 (e.g. .5 MHz). The resultant spectrum is as in Fig. 1. When the two resultant transposed luminance and colour signals (E Y , E C ) Fig. 2 are combined at 7, the result is amplitude as well as frequency modulated. The amplitude modulation cannot be directly recorded on a two state recording medium, e.g. a video disc, whereby the invention proposes the conversion of the signal E Y  + E C  to a two state signal, Fig. 2d, having a change of state at a cross over point of the signal E Y  + E C . Such a two state signal is produced at 8 by a limiter on bi-stable circuit, and is said to contain all the information to afford, when reproduced from the video-disc, the reproduction of the luminance and colour signals in their original states. The presence or effect of various inter-carrier product components in the recorded signal, e.g. F Y -2F C , 2F Y -F C , can be removed or reduced by frequency reduction and/or filtering. In a second recording method, Fig. 5, the signal E Y  is modulated at S on to a carrier with twice the desired frequency and the result frequency halved. This results in a separation of the leading and trailing edges of E Y . The leading and trailing edge signals are then shifted in respectively opposite directions in accordance with the colour signal E C  by means of variable delays R 1  (leading), R 2  (trailing) of the bucket brigade kind and an inverter I. By shifting the frequencies of the signals E Y  and E Y  up, e.g. À5 MHz a sound signal band may be recorded, e.g. at À25 MHz (Fig. 6 not shown). When the original sound signal has a carrier higher than the original colour carrier, e.g. 5À5, MHz as against 4À43 MHz a common mixer signal at an intermediate frequency, e.g. 5À3 MHz must be used to shift the two signals down in frequency without overlap. The recorded spectrum may be extended to include a band (E CS ) for a SECAM type signal and well as one for a PAL/NTSC type (E CP ) (Fig. 8, not shown). A reproduction circuit is described (Fig. 9, not shown) using separation filters (11), frequency demodulator (FM) to give luminance signal E' Y  and a mixer circuit (13, 14) to give the colour signal E' C .

Title: X-ray film-control apparatus
IPC: G03B42/02
Filed: 1967-09-08
Abstract: 1,206,167. Serial exposure X-ray spot film device. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 8 Sept., 1967 [9 Sept., 1966], No. 41188/67. Heading H5R. In an X-ray spot film device, on inserting the cassette 11 into the cassette carriage 4 whilst said carriage is positioned on the left hand side of Fig. 1, one dimension of the cassette used is recorded for example by feelers F 1 , F 2  or F 3 , and on translating the carriage to the ready position shown in Fig. 1 the transverse dimension of the cassette is recorded for example by means of feeler F 4 . Other contacts, e.g. Oe, Kt, (Fig. 3 not shown) are activated if diaphragms e.g. an oesophagus diaphragm and/or compression diaphragm are used to obtain a selected field of exposure. The activation of the contacts mentioned above activates an electrical network and results in the activation of the appropriate contacts K 1 -K 4  and magnetic devices M 1 -M 3 . A possible result of this activation is shown in Fig. 2. When cassette 11 is moved into the exposure position magnet M 2  lifts channel 15b and wheels 13 follow the channel so that the upper half of the cassette is aligned with the exposure position 5, and contact K 4  operates magnetic pawl M 1  so that the left hand part of the cassette is positioned over point 5. Completion of the exposure returns the cassette to the rest position shown in Fig. 1, and the activation of a new exposure causes the remaining quarters of the cassette to be automatically positioned in sequence according to the co-operation of contacts K 1 -K 4  and magnetic devices M 1 -M 3 . If only the oesophagus diaphragm is used, devices M 2  and M 3  are not activated but contacts K 1 -K 4  position the right and left halves of the cassette appropriately, and if no diaphragms are used, one of these contacts positions the cassette centrally. In order to fully utilize the available area of cassettes having different sizes, the channels 15a, 15b may be replaced by double channels (Fig. 5, not shown), and the cassette is delivered to the appropriate channel by magnetic lifting devices similar to M 2  and M 3  according to the contact F 1 -F 3  activated. For cassettes of differing transverse dimension, an oesophagus diaphragm which is of variable width may be fitted. This may be activated by an additional contact F 5  placed near but to the left of F 4 , and the diaphragm may be operated by a magnetic plunger and lever system (Fig. 4, not shown) which in this embodiment widens the diaphragm when F 5  is activated. The control signals from the various contacts are manipulated by a pair of electronic devices which initiate a response from the appropriate output, i.e. contact of magnetic device, at an appropriate time, so that on activating an exposure, the whole subsequent series of operations is automatic.

Abstract: 1,192,375. Electrically operated warning devices. COAL INDUSTRY (PATENTS) Ltd. 15 Sept., 1967 [16 Sept., 1966], No. 41497/66. Heading G4F. Apparatus for a machine (e.g. a long wall coal machine) which delays start-up and gives a warning during the delay, has a separate supply from the machine and prevents the machine being started if the warning is not emitted. Upon operating the start switch a delay switch energizes an oscillator feeding a warning signal to a loud-speaker. After the delay the machine is normally started and the warning terminated. However, a microphone is associated with the loud-speaker and if the warning is not received the start-up is prevented. The delay and warning device is energized by a battery charged from the main supply and the apparatus is arranged so that it may be added to the machine without modifying the machine circuit.

Title: Apparatus for cutting pipes
IPC: A01G25/02
Filed: 1976-10-06
Abstract: 1516769 Apparatus for cutting openings in pipe walls W HEGLER 6 Oct 1976 [3 July 1976] 41538/76 Heading F2P Apparatus for cutting openings in one wall of a double walled pipe walls comprises at least one knife disposed inside or outside the pipe and a movable element adapted to be moved by signal means whereby the knife and the pipe wall are brought into contact so that the knife cuts an opening in one pipe wall and pipe. Preferably the pipe feeding means for feeding the pipe past the knife is externally supported by a carrier means which includes a thrust roller for pushing the pipe against said knife and a counter-roller which is movable in a transverse direction jointly with the thrust roller. In Fig. 1 a pipe consisting of an outer tube 1 having helical corrugations and a smooth inner tube 2 travels over a floating mandrel 3 carrying a knife 10, through fixed guide means comprising a roller 4 revolving synchronously with the pipe forming machine and an idling counter-roller 6. The pipe is also located by four guide rollers 7 in a carrier frame 9 capable of being displaced in a vertical direction. In the condition shown in Fig. 1 the pipe slightly sags in the downward direction so that it does not come into contact with the knife 10. When an opening is to be cut in the pipe wall a signal, preferably emanating from the pipe forming machine, causes the carrier frame 9 to be lowered (Fig. 2, not shown) so that the pipe will arch slightly about roller 4 so that the pipe wall contacts the knife 10 which cuts a chip out of the inside wall of the pipe. In a second embodiment (Figs. 3 and 4, not shown) the knife is located on the outside of the pipe and the pipe traverses a cylinder which reolves about an axis parallel to the pipe axis and is fitted with radially movable knives held in holders that can be advanced towards the pipe when a cut is to be made therein. Apparatus for cutting openings from the inside and apparatus for cutting openings from the outside may be consecutively located and the distance between them can be adjustably controllable. This arrangement (Fig. 5, not shown) is of particular application in producing a trickle irrigation pipe consisting of a transversely corrugated tube and a smooth inner or outer tube so that transfer holes are produced from the inner tube to the helical space between the inner and outer tubes and exit holes are produced in the outer tube. The exit holes can be in the crest or flanks of corrugations and if desired they can be in pairs.

Title: Production of webs of film materials
IPC: B29C48/31
Filed: 1972-09-07
Abstract: 1409802 Randomly electrostatically charged films HOECHST AG 7 Sept 1972 [9 Sept 1971] 41602/72 Heading B5B [Also in Division H1] Films are produced by melt-extrusion and, as the film leaves the die, it is given an electrostatic charge. The distribution across the film of the charge being applied is varied with time. Thus, in Fig. 2, the extruded film 2 is charged by electrode 9 which gives an uneven charge across the film and varies its distribution by moving transversely of the film. A known electrode 11 may be used additionally to charge the film to assist in sticking it to a cooling roller. Alternatively the first charging electrode may stay in a fixed position but be rotated, the variation in distribution being achieved by using an electrode with a random distribution of high-spots on its surface. Figs. 3 to 6 (not shown) illustrate some design of electrode suitable for use. Alternatively, the electrode may be supplied with a varying current so that the total charge varies. Films (e.g. of polyethylene terephthalate) so produced do not have a constant cross-section in which, when rolled up, the thicker portions are superimpoed. They can, therefore, be rolled more compactly.

In means for resiliently mounting a motor vehicle body 23 to a chassis frame 10 an axial extension 13 of a rubber ring 12 is engaged within an aperture 11 in the frame 10 and the sleeve 15 of a part A is passed through the ring 12 and through another rubber ring 17 on the underside of the frame 10 a radial flange 14 on the part A bearing upon the upper face of the ring 12. A complementary securing part B, with a pair of diametrically-opposed inwardlyextending tongues 27 pressed out from the base of a lower thickened portion 20a of a sleeve 19, is introduced into the sleeve 15 so that a head flange 18 engages beneath the ring 17. The parts A, B are then pressed together, e.g. by a pressure of 500 p.s.i., until a lip 16 at the lower end of the sleeve 15 abuts the flange 18 of the part B whereupon a tool 28 is inserted into the sleeve 19 of the part B to force the tongues 27 outwardly which results in the fracturing of the walls of the sleeve portion 20a to form outwardly-directed projections 20 which lockingly engage the lip 16. After the tool 28 has been withdrawn the rings remain in compression and the body 23 can be secured by a bolt 25 which, with the interposition of washers 24, threadedly engages a screw-threaded restricted portion 21 of the sleeve 19 of the part B. In a modification, Fig. 6, (not shown) the sleeve 15 of the part A diverges inwardly at its lower end to provide additional strength.
