Title: Alloy coating post-treatment
Inventor: STEINE HANS-THEO
IPC: C23C4/18
Filed: 1988-09-22
Abstract: A process for coating a substrate comprises applying on to the substrate a layer of a self-flowing metal-base alloy by thermal spraying, and subjecting at least a zone of the layer to inductive heating, by means of an inductor, at a frequency of from 0.5 to 100 kHz and a power of from 1 to 150 kW, whereby the layer is fused or sintered into the surface of the substrate, and the depth of penetration of heating of the substrate is controlled according to the strength of the induced field and/or the size of the inductor and/or relative movement between the inductor and the layer being treated. The frequency may be varied within the range specified by hand or automatically. The size of the inductor may be such as to heat an area of 5 to 200 cm<2>. The frequency of the relative movement between the inductor and the layer being treated may be controlled by the use of a thermocouple element. In the specific example a pressure roller is spray coated with an alloy of Ni-Cr-B-Si admixed with tungsten carbide. The parameters in respect of frequency and power were established on a test portion. The substrate may be a coating roll of the type used in the paper industry.
Patent GB-2226114-A (GB)
Title: Emission system
Inventor: COLEMAN CLIVE IAN
IPC: F42B12/46
Filed: 1988-12-16
Abstract: A system for the emission of a fluid as a vehicle re-enters the Earth's atmosphere at high speed, the rate of release of the fluid from a reservoir being governed by kinetic heating. Heat from the vehicle's nose 2 is conducted to the fluid 5 from a heat-collecting panel 3 by means of a tube 4 in contact with the fluid. When the pressure of the fluid in the reservoir exceeds a predetermined threshold value a spring-loaded valve 7 is opened to release the fluid. The tube may be used to inject fluid from the reservoir to the nose for the purpose of alleviating the effect of plasma sheating. The system requires no electrical power source and has an inherent self-regulating capability. The principle of operation can equally be used in other liquid dispensing applications dependent upon re-entry deceleration and kinetic heating, for example the control of fuel to thrusters designed to maintain the vehicle's momentum. <IMAGE>

Title: Method of assembling a piston-and-cylinder unit with a force transmission element
Inventor: REINARTZ HANS-DIETER
IPC: B60T11/20
Filed: 1989-07-11
Abstract: In the method, for assembling a tandem master cylinder and a vacuum brake booster of a hydraulic brake system for automotive vehicles, air is injected via the pressure connection (19) of the pressure chamber (18) associated with the push-rod piston (2). Simultaneously, the push-rod piston (2) is moved inwards (to the left). The pressure increase in chamber (18) is measured during the movement of the push-rod piston and, thus, during the movement of the central valve (6) accommodated in the push-rod piston. As soon as the closure member (5) of the central valve is seated on the valve seat (4), the air pressure will increase in the chamber (18). In the curve of the "pressure-against-central-valve-travel" diagram, which curve indicates the pressure increase, a trigger point is established at a measured distance on the abscissa of the diagram, and this determines the number and/or sizing of spacing washers (8) to be arranged between the pressure element (9) and the push-rod piston in order to achieve a reduction of the lost travel of the central valve. In an alternative method, the force acting on the piston is measured as it is moved against springs 12, 13. At the point of valve closure spring 13 no longer acts against the spring 12 and a sudden increase in force on the piston is detected. …<IMAGE>…

Title: A process for the direct or indirect electro-deposition of a highly corrosion resisting crack-tree technical hard chromium plating layer
Inventor: KOHL MARTIN
IPC: C25D3/04
Filed: 1990-10-03
Abstract: A process for the direct or indirect deposition of a highly corrosion resisting technical hard chromium plating layer on the surface of a metallic workpiece from an aqueous working electrolyte containing chromic acid and sulphate ions is described. In a process wherein the current yield of the working electrolyte is optimised by the addition of at least one saturated aliphatic sulphonic acid having at the most two carbon atoms and at the most six sulphonic acid groups and or by the addition of salts or halogen derivatives thereof and the deposit has a thickness of at least 2 mu m and a hardness exceeding 9oo HV o.1, the deposition is effected with direct current pulses, the pulse frequency lying in the range between a lower critical pulse frequency dependent on the cathode current density setting and an upper critical pulse frequency point dependent on the optimised current yield at the same current density. The procedures for determining the lower critical pulse frequency and the upper critical pulse frequency point are described. The on-off ratio in the range between the lower critical pulse frequency and the upper critical pulse frequency point is kept sufficiently low for the deposit to remain bright and substantially crack-free.

Title: Form-fill-seal apparatus for simultaneously packaging two streams of articles
Inventor: MCDONALD IAN WILLIAM
IPC: B65B9/073
Filed: 1991-05-07
Abstract: Form-fill-seal apparatus for simultaneously packaging two streams of articles 15, a sheet of packaging material 17 being brought around the adjacent articles, a central loop portion 6 of the material being passed between the streams of articles and between outer edge portions 4, 5 of the packaging material. The packaging material (17) is heat-sealed through the combined thicknesses of its central portion and its edge portions, e.g. by rollers 27. without introducing a sealing device between the articles. Adjacent packages can be separated by cutting through the central loop portion of the packaging material which does not seal to itself, for example using a blade 29 positioned along the line of flow of the articles. The present invention enables hitherto proposed single stream form-fill-seal apparatus to be modified relatively easily to enable twin streams of packages to be produced without increasing the speed of the packaging material or the linear speed of individual articles.   <IMAGE>

Title: Borehole drilling and telemetry
Inventor: COMEAU LAURIER EMILE
IPC: E21B47/18
Filed: 1991-05-15
Abstract: Improved techniques are provided for drilling a deviated borehole through earth formations utilizing a rotary bit 22 powered by a drill motor 24, and for obtaining information regarding the borehole or earth formations while drilling. An accelerometer 60 is positioned below the drill motor 24 and within a sealed cavity of a housing 42 fixed to a drill motor sub, and a transmitter 62 within the sealed cavity transmits acoustic signals indicative of inclination determined by the accelerometer to a receiver 70 provided in a measurement- while-drilling tool 46. The MWD tool is provided within a non- magnetic portion of the drill string, and further houses accelerometers and magnetometers for determining borehole orientation. Both bore hole inclination signals and borehole orientation signals are transmitted to the surface by the MWD tool, and the drilling trajectory may be altered in response to the signals where required. These techniques are advantageous as they provide monitoring of borehole inclination near the bit rather than at a distance of typically 20 to 100 feet from the bit as with conventional techniques. <IMAGE>
