A magnetic valve has a coil, an armature, and a permanent magnet arranged coaxially with the coil, wherein the permanent magnet is formed as a plate with magnetic lines of force extending in the same direction or oppositely to the magnetic lines of force of the coil, and the armature is formed as a valve body opening in direction toward a lower pressure.

Apparatus and method for shucking scallops by subjecting scallops simultaneously to heat and vibration to remove scallop meats from scallops progressively and reducing prolonged exposure of the scallop meats to an elevated temperature before evisceration to avoid cooking or affecting the adductor muscle.

The positive electrode for a lead acid electric storage cell is made by preparing by a chemical route particulate beta lead dioxide, mixing together the beta lead dioxide with a relatively low proportion of a binder, and applying the mixture to a perforated electrically conductive support structure.

A positive electrode 10 for a lead acid electric storage cell 24 (Fig. 2) is made by chemically preparing lead dioxide. The lead dioxide is then applied to a support structure 14 with a binder, or poured into a permeable, tubular container located about a current collecting rod.

The invention relates to a telescopic tube unit making it possible to adjust the position of an apparatus which it supports. The tubes (2, 3, 4, 5) sliding one in the other are drawn-out profiled tubes, and on their inner surface there are longitudinal crimps (7) in which is locked a bar (8) of hardened steel on which there roll ball bearings (9) mounted on the upper part of the surface of the jac...

Process for solid refuse disposal in which a vertical shaft furnace is maintained at 30-250 psia, part of the recycle-condensate is filtered to form liquid waste a portion of which is incinerated with a minor part of the product gas to form hot exhaust gas used to heat feed water in steam boiler zone, and energy from the resulting steam is recovered as part of the process energy requirement.

Glass microfilaments of length 0.5-12 inches and diameter 0.5- 40 mu are produced by forming a film of molten glass across coaxial blowing nozzle 5, and blowing it with gas from inner nozzle 6 which has at least one enlarged portion 20, to produce tubular film 12 having a weakened section in its wall. Entraining fluid 14 produces a pulsating pressure field which breaks weakened film 12 into plura...

A suspension of an aqueous solution of a water-soluble polymer in an organic liquid forming a continuous organic phase, said suspension containing, as an emulsifier, a mixture of two copolymers which are similar but differ in their content of basic nitrogen by 0.1 to 1.5 percentage points.

PURPOSE:To improve adhesive proerty and flexibility, by attaching a specific thermal reaction type urethane resin having one or more sulfosuccinate groups in a molecule and a specified rubber swelling compound on the surface of thermoplastic synthetic fiber. CONSTITUTION:On the surface of the thermoplastic synthetic fiber, aqueous solution of the thermal reaction type urethane resin, which has at ...

After the input of at least one reference size value as for example the diameter of a shaft to undergo grinding, all adjustment values, necessary for machining a work- piece on a grinding machine, undergo input into a computing unit, such as a mini-computer and undergo display. The worked out adjustment size values may be adjusted by manual inputs and are changed into pulses by way of a pulse gene...

In floating-caliper disc brakes, the friction in the caliper guides hinder movement of the caliper in the brake release direction, thus, increasing the drag of the brake when it is not operated. According to the present invention, the reaction portion of the caliper is provided with an applying piston of small axial length whose axial movement is limited to an amount equal to the required brake cl...

A polyurethane coated polyvinyl chloride or vinyl chloride co-polymer which resists discoloration is provided by coating the substrate surface with an aqueous dispersed polyurethane treated with a mono-acid halide, mono-acid anhydride, carbethoxy cyclic imide or monoisocyanate. The coated composite even when subjected to temperatures in excess of 100 degrees C for extended periods resists discolor...

Ceramic free metal powder is produced by forming a metal melt in container 16 from consumable arc electrode 15 and controlling the heat balance in the container so that a solidified metal skull is formed on the inside wall of the container the molten metal overflows from the container at 18 and is atomised by a gas stream at 19. The overflow may be heated by plasma flame 27.

In an automotive disc brake, the main hydraulic seal 18 is arranged in a trapezoidal annular groove 21 so that it distorts into a parallelogram shape during brake application and provides a resilient retraction force for the piston 17 in the cylinder 16 when the cylinder is depressurised. A combined dust seal and retraction control means 19 incorporates an abutment means 26, 28 which grips the pis...
