Abstract: The invention relates to a method and an apparatus for the manufacture of heat exchanger elements. A pair of strips of weldable material e.g. high-grade steel is welded together in such a way that on both sides a longitudinally extending weld seam is formed, said pair of strips between said longitudinally extending weld seam defining a longitudinal channel which extends parallel to the weld seams and which serves for the conduction of heating or cooling agents. At least one of the strips is first provided with at least one longitudinally extending groove and is longitudinally welded to the other strip of the pair of strips in such a way that the groove forms with the part of the other strip covering it a longitudinal channel. A liquid filler material is poured into the longitudinal channel and solidified by cooling to below its freezing point. The pair of strips with the solidified or frozen filler material serving as a supporting core is subsequently shaped by plastic deformation of the walls without cutting in such a way that the longitudinal channel hereby acquires the desired shape and finally the frozen filler material is rethawed and removed from the deformed channel.

Abstract: A high-speed switch machine for actuating railroad switch points. The machine has an electric motor which drives a hydraulic pump. The pump supplies pressure fluid to a hydraulic cylinder adapted to move the switch points from an initial to a second limit position. A four-way, two-position hydraulic control valve directs fluid to the cylinder such that the cylinder automatically operates in an extension and retraction cycle. The uni-directional motor and two-position control valve minimize response times of the actuating components so that the switch points are thrown in a short time period.

Abstract: A method of increasing the abrasion resistance of glass articles is disclosed. It has been found that by providing a vitreous substrate with a micro-roughened surface and an overlayer of dry lubricious organic coating, substantially increased lubricity and abrasion resistance is obtained. When the micro-roughened surface is provided by bonding a discontinuous distribution of discrete particulate material to the surface, a substantial increase in abrasion resistance and lubricity is realized even without the overlayer of dry lubricious coating thereby making the present invention particularly adaptable to use in the hot end of a glassware manufacturing process. Further, when the particulate material is fusible at about the annealing temperature of the glassware and is applied at the hot end, the particulate material will protect the glass surface through the hot end by bearing the major part of any loads created by contact between the glassware and other objects in its transport through the hot end. Upon being annealed, the particulate material will fuse and self-heal itself of any damage caused by such contact. 
     In the preferred embodiment, glass frit of a tow-fusing temperature having a size range of between under 1 micron to about 100 microns is applied over between 5 percent and 85 percent of the surface area of glassware. The frit is then fused to the glassware and upon cooling, an overlayer of dry lubricious organic coating is applied. The frit is preferably applied electrostatically while the glass is hot through dry powder deposition or with a liquid carrier. Great uniformity in applying minute amounts of particulate material has been achieved by on-site grinding the particulate material to an air-carriable size with a fluid energy mill. The particulate material is air exhausted from the mill and directly applied thereby avoiding problems presented by agglomeration of the low micron range particles.

Abstract: 1.

Abstract: The invention provides a method for identifying algae in a water sample and to apparatus which may be used in the method. More particularly, an aqueous fluid containing the algae is passed through an adapted flow cytometer which is operated with a high intensity light source, e.g. a laser, operating at at least one excitation wavelength. At least three parameters are determined from the output of the flow cytometer, one of these parameters being chlorophyll fluorescence. The other parameters may be forward light scattering, perpendicular light scattering, backward light scattering, pulse length and/or shape of the scattered signals, fluorescence, and pulse length and/or shape of the fluorescence signals. The apparatus of this invention comprises at least one high intensity light source, means for providing a liquid jet, and a system of detectors arranged to measure chlorophyll fluorescence and at least two other of the parameters identified above. In order to separate the light output from the flow cytometer into components which can yield useful measurements, a system of partially reflecting mirrors and dichroic mirrors is used. The invention can be used to monitor water purity.

Abstract: A machine for burying slurry, sewage, or other soil-improving fluids has a hollow straight forward-leaning tine which carries at its bottom end an arched, forward-sloping delta-shaped shoe for lifting the soil into the form of a tunnel. The hollow interior of the tine opens through the roof of this shoe, and slurry is delivered through the tine into the cavity under the shoe. A free-running vibrator on the tine vibrates it and the shoe vertically. The tine is resiliently loaded by a spring to its working position, and the reaction of the spring is applied directly to a reaction lever separately pivoted on a subframe carrying the tine. The spring reaction biases the lever downwards, and the lever is supported at its rearward end behind the tine by a roller which closes the slit formed by the tapered leading edge of the tine.

Abstract: In one form of stripline antenna, the strip turns through successive right-angel corners to form successive multi-cornered cells in which the lengths of the longitudinal and transverse strip sections are such that the summed radiation from each cell radiates in the same direction and with the same polarisation direction, e.g. as described in European Patent Application No 79301340.0 (Publication No 0007222). In the present disclosure, the distribution of radiated power along the array is varied, e.g. to maximise it at the centre, by varying the absolute lengths of these strip sections as between cells while maintaining their required relationships, e.g. by progressively increasing these lengths towards the centre of the array in order to increase the radiated power accordingly. This compares with the previously known method, viz varying the strip width.

Abstract: A motor cycle disc brake having a disc (15) secured by its outer peripheral margin to the rim (22) of a wheel (16), which is rotatable about an axle held by a pair of fork legs (12). 
     A brake caliper (11) is secured to a fork leg (12) and straddles the inner periphery of the disc. The disc (15) is secured to the wheel rim (22) by bolts (17) which allow the disc (15) some axial play relative to the wheel to compensate for any mis-alignment between the wheel and the forks. 
     Also the caliper (11) is fixed to the fork leg (12) by a pair of securing members (35) and (41). One of the securing members (a pinch bolt) (41) engages in an open ended slot (40) in a lug (32) on the fork leg (12) so that the caliper (11) can be released from the fork leg (12) without completely undoing the pinch bolt (41). The other securing member (35) is a quick release pin (35).
