Title: Pipe coil for hot water panel heating - is formed with adjacent bends touching each other
IPC: F24D3/14
Filed: 1976-02-27
Abstract: A pipe (3) of metal or plastic carries low pressure hot water and is embedded in a floor, wall or ceiling to provide a panel form of surface heating. It is arranged in a series of loops with bends (41) of large radius according to the minimum bending radius which the pipe can accept without fracturing. The straight lengths between bends are not parallel but taper towards each other so that the sides of adjacent bends touch each other. They are held together by clips (40) or are fixed together to the floor by a common clip at their point of contact. The arrangement enables a greater length of pipe to be accommodated on a given surface for the same minimum bending radius.

Title: Joint for thin wall pipes of ductile metal - has end of tube deformed by axial force to match mating pipe
IPC: F16L17/035
Filed: 1976-04-02
Abstract: The method of making joints with thin-walled pipes of ductile metal such as aluminium or copper uses a fitting (1) with a toroidal chamber (8) formed in one end. The other end of the fitting (1) is attached to the pipe (3) with a conventional lip seal (4). The thin walled pipe (2) is then forced axially into the toroidal chamber (8) so that the wall of the pipe (10) is deformed to match the shape of the toroidal chamber. A leak-tight joint is thus formed which can resist axial loads. The system is particularly for pipes used for irrigation systems.

Title: Terephthalic acid prepd by catalytic oxidn of p-xylene - giving prodt suitable for direct use in polyester
IPC: C07C51/265
Filed: 1976-04-09
Abstract: Terephthalic acid is continuously produced by introducing into an oxidn. zone, a mixt. of a solvent, consisting of acetic acid contg. 1-7% water, and p-xylene contg. a catalyst with a ratio of solvent to p-xylene being maintained at from 4:1 to 7:1 by wt.; an oxygen contg. gas is passed into the oxidn. zone which is maintained at 160-180 degrees C and the residence time of the mixt. in the oxidn. zone is from 30-120 mins. The catalyst is a mixt. of a Co cpd., a Mn cpd. and a bromide, the Co being 1200-2500 ppm. of the solvent, the Mn being 1-30% of the Co, and the bromide is at least 1.5 times the weight of Co+Mn. In a further process as above, the gaseous prod. is passed to a waiting zone for at least 30 mins. at a temp. ranging from 50 degrees C below to 25 degrees C above the reaction zone, then the mixt. is passed to a sepn. zone where the solid terephthalic acid is sepd. The prod. is used to make polyethyleneterephthalate. Previously the product from p-xylene oxidation has required expensive purification to obtain sufficiently high quality for polyester mfr. The above gives high quality terephthalic acid without excessive combustion of acetic acid and the prod. only require a simple treatment to enable it to be satisfactory for polyester mfr.

Title: Adjustable bicycle-type home trainer - has frame adjusted by comparison of projection of back of user onto screen
IPC: A63B22/08
Filed: 1976-04-16
Abstract: A home trainer using substantially a bicycle frame without a front wheel and front forks, and suitably attached to a support with rollers for the rear wheel, has an adjustable frame to adapt to the user's body. The crossbar (2) attached to the remainder of the frame (1,3, 4) in a conventional manner, supports at upper crossbar (16) permitting its height to be adjusted. This allows the height of the saddle (23) and handlebars (32) to be altered. The saddle can also be moved rearwards from the upper crossbar, and similarly, the handlebars can be extend forwards. To ensure correct positioning of the spine of the user, the shape of the user's back is projected onto a screen and measured against a set of reference curves.
Patent FR-2309754-A1 (FR)
Inventor: WEHDE HEINZ
IPC: F16C39/06
Filed: 1976-05-03
Abstract: On a device which has a stator (1) and a rotor (3), magnetic bearings (6, 16) are provided for the generation of radial and axial bearing forces. These magnetic bearings comprise magnet-pole rings (12) on the stator and directly opposite the said rings, magnet-pole rings (13) on the rotor. The magnet-pole rings are axially or radially magnetised, and the magnet-pole rings (12) of the stator at least are permanently magnetised. By virtue of the coaxial arrangement of the magnet-pole rings, the permanent-magnet fields generate not only bearing forces in the direction of magnetisation but also transversely thereto. To provide stability of support for the rotor, an electric winding (17) is arranged between the magnet-pole rings of the stator, the magnetic field of which is regulated in order to weaken or strengthen the permanent-magnet fields as a function of deviations in the position of the rotor (3) in the direction of magnetisation. These magnetic bearings are of simple construction and the energy requirement for the bearing forces which can be achieved with them is relatively low.

Title: Modification of polymer surfaces by electron bombardment - using low pressure gas discharge plasma and coated electrodes
Inventor: KREISELMEIER HANS-GERT
IPC: D06M10/02
Filed: 1976-11-15
Abstract: Modification of surfaces of polymers, e.g. textile fabrics or fibres, or films is by electron bombardment in low pressure gas discharge plasma in wich the polymer is passed across or between negatively charged sheet electrodes. These are shielded on the other side by parallel earthed metal plates, and coated on the polymer side with an opt. conductive material pref. different from the electrode itself. Distance of the polymer material from the electrode is greater than the dark spaced formed over the electrode. Method may be used for treatment of polymer surfaces to improve hydrophilic, adhesion or dyeing properties, and formation of free radicals to allow grafting. Equipment costs are much less than for electron accelerators, and precautions required in use are reduced. Positive ions discharged from the electrodes release sec. gamma-electrons from the coating, which are accelerated across the dark space below impact with the polymer. Treatment times are reduced to a few seconds. Activation, grafting and opt. monomer formation can be carried out simultaneously.

Title: Optical control for template guided metal cutting torch - employs TV camera with circular beam sweep whose optical pulses provide control signals
Inventor: DEASLEY PETER JOHN
IPC: B23Q35/127
Filed: 1976-12-06
Abstract: The oxycutter follows a cutting path determined by an optical system which follows a model. This is performed by a TV camera with circular sweep of the beam. The optical pulses are converted into electrical control signals for the cutter. A TV camera with a circular sweep optically explores a line or edge such that the sweep point and a reference point appear at separate points on the circumference of a circle. The instantaneous difference between the two points is converted into electrical signals to control motors driving the cutter. The central point of the circle is kept on the line being explored.
