Title: Plastics lined pipes prodn - by introduction of compressed lining and allowing the lining to expand to grip the pipe wall
IPC: F16L58/10
Filed: 1971-06-24
Abstract: Thermoplastic resin lining is introduced into a pipe with a lengthwise passage whose dia. is smaller than that of the lining, by compressing the lining in a radially inwards direction in order to decrease its dia., placing the lining in the pipe, and allowing the dia. of the lining to increase so that it is firmly gripped against the inside face of the pipe. The lined pipes can be produced rapidly e.g. steel pipes lined with polypropylene.

Title: Polyolefin fibres prodn - directly from monomer, using agitation by oscillation, vibration, ultrasonics or gas stream
IPC: D01F6/04
Filed: 1973-03-22
Abstract: Polyolefin fibres are produced by polymerising a monolefin in a liq. hydrocarbon in the presence of a reduced halide or oxide of a Gp IVA, VA, or VIA transition metal, with agitation by oscillation, vibration, ultrasonics or by introducing gas. The fibres are suitable for synthetic paper mfr. and they are continuously produced directly in the polymsn. vessel. The problem of firm adherence of fibres to a rotary turbine stirrer is avoided. The use of a very active catalyst (Ziegler or Phillips type) leads to a very high yield of prod. w.r.t. catalyst and eliminates the need for de-ashing.

Title: Chlorine dioxide prodn. as part of paper paste mfr. - by reacting sodium chlorate with sodium sulphate and hydrochloric acid and removing the salt (BR270776)
Inventor: SWINDELLS RICHARD
IPC: D21C11/00
Filed: 1974-12-06
Abstract: In a process in which a paper paste is produced by contacting a cellulosic fibre with a paste forming liquor contg. Na2S and NaOH, sepg. the paste from the used liquor and regenerating the liquor to obtain a white liquor which is recycled as part of the liquor added to the fibres together with added Na2SO4 to compensate for the loss of soda and S, and bleaching using chlorine dioxide and purifying the paste, the ClO2 is formed by reacting NaClO3 with HCl in the presence of H2SO4 and a mixt. of NaCl and Na2SO4 is recovered, the Na2SO4 being used to supply the Na and the S as above. The amount of feedstock for making the ClO2 is reduced compared with prior art and since the NaCl is sepd. from the Na2SO4, no build up of salt occurs to produce a dead charge.

Title: Nuclear combustible bundle of sheathed rods in shell - has corrugated shell wall giving uniform trouble-free overall cooling
Inventor: BOUDAILLE JEAN
IPC: G21C3/324
Filed: 1975-09-19
Abstract: A nuclear combustible assembly, consisting of a bundle of sheathed rods in a shell through which a cooling fluid passes, has corrugations in the shell. Each rod has a helical wire wrapped round it over most of its length, fixing the min. sepn. between the rods and between the outer rods and the shell. The corrugations extend over the full height of the shell and project into the channels formed between the shell and the peripheral rods. Pref., the shell has a hexagonal section. The invention avoids the inconveniences of existing installations. These are the need to put components on the surface of the shell to limit the flow of cooling fluid at the shell and make the overall flow more uniform. Such components are difficult to fit and the joints can rupture under the effect of heat and neutrons, or the components can rupture under the effect of vibration.

Title: Variable speed fan drive system - has orifice restricting flow to piston and cylinder controlling motor torque
IPC: F04D25/04
Filed: 1975-09-29
Abstract: The fan drive system comprises a constant pressure ring main circuit from a motor driven pump to, for example, three variable capacity motors (3) driving three fans (4). The motors are connected in parallel with each other and in series circuit with the pump and each has a piston and cylinder device (5) supplied with pressure from the ring main. A variable restrictor controlled by a temperature probe sets the pressure acting on each piston and cylinder device so that each fan is speed controlled in accordance with temperature. The variable orifice (8) controls the flow of hydraulic fluid to the reservoir (10), varying the piston and cylinder pressure, and hence motor torque.

Title: Monitoring vacuum deposition process - by determining the electromagnetic wave transmissivity
IPC: G01R27/02
Filed: 1975-12-09
Abstract: Vacuum deposition of silver, gold, or copper on a transparent plastics film is monitored by applying electro magnetic radiation of 1.5 to 4 micron wave-length to the metallised film and detecting the signal transmitted through the film. The value of the detected signal is correlated to the surface resistivity of the film. Used for vacuum deposition of resistance heater elements for deciding and demisting. It allows detection and close control of the rate of deposition by control of rate of film transport, power to the electron gun, rate feed to the electron gun crucible or other control of the rate of deposition.

Title: Cinema or TV stereoscopic image production - uses two oppositely polarised films covering left and right images viewed alternately, through polarised spectacles
IPC: G03B35/16
Filed: 1976-06-01
Abstract: Stereoscopic images are viewed in relief when obtained in either colour or black and white from TV or cinematic screen. Images are observed through polarised spectacles from recordings made by two cameras located such as to represent viewing by an observer. A camera with two objectives (O1, O2) takes views of a subject (S) at angles representing eyes of an observer. Recording is effected by a rotating mirror (H) which directs the image from left or right (D) objective lens for recording. Mirror and recording medium are synchronised by a servo mechanism. Reproduction of images is achieved by passing a rotating film in front of the image. This film has vertical and horizontally polarised areas moved in sync. with a reproducing equipment image.
