Abstract: A device for equalising the mean pressures prevailing in the working spaces of the cylinders is allocated to a double-acting multi-cylinder Stirling engine. This device consists of at least one transfer duct (29) arranged in the cylinder wall adjoining the cylinder bore (2) at the level of the theoretical pressure equality between the working space (9) on the burner side and the working space (10) on the transmission side, furthermore of an upper sealing piston ring (7) interacting with passage grooves (22), allowing working gas through primarily from the working space (9) on the burner side only in the direction of an intermediate space (21) and designed as a nonreturn valve, and furthermore of a lower sealing piston ring (8) temporarily exposing the transfer ducts, controlling the beginning, duration and end of a pressure compensation and designed to shut off on both sides. This measure inevitably makes the pressure charactersistics of all working cycles operative at the top and bottom sides of the pistons more uniform; in addition, the bearing conditions at the bearings of the Stirling engine are uniformly favourable at all points, having an advantageous effect in terms of a uniform load distribution and a uniform torque characteristic. The uniformised mean pressures of the cycles which are achieved have the effect of a uniformly distributed power regulation and high efficiency since a uniform distribution of the volumetric flows of fuel fed in between the individual burners and hence a uniform heat distribution between the working spaces filled with equal proportions of the total working charge is guaranteed. <IMAGE>

Abstract: A high frequency power amplifier consists of a large number of serially connected transistors (1 ). The base connections of the transistors are connected to a potential divider consisting of reactive components, usually capacitors (3), which form part of a tuned circuit (3,6,7) which is resonant at the frequencies at which the amplifier is to be used. The resonant currents flowing in the potential divider ensure that sufficient base current is available for the transistors to provide the required amplification.

Abstract: A self-hardening composition may be made by mixing an alkaline earth metal halide, preferably calcium or magnesium chloride or mixture thereof, calcium metasilicate, sodium fluorosilicate, an aluminum silicate clay such as kaolin, sodium silicate and water. A pre-mix for use in the formation of such a composition can be made up by omitting the sodium silicate and water or by incorporating dry sodium silicate with the other ingredients. 
     The self-hardening composition formed in accordance with the invention may be used as a bonding composition which will provide insulation against temperature extremes whilst retaining bond strength and avoiding the emission of toxic fumes when subjected to extreme heat or fires. 
     Composite materials may be made up by mixing expanded aggregate materials and/or reinforcing fibers with such self-hardening compositions. These composite materials may be employed in the production of laminates by adhering layers thereof to facing sheets or may be employed as such in the formation of insulating structures by pressing or extruding such composite materials to produce a desired shape.

Abstract: A process for recovering interferon comprises forming, from a solution containing an interferon produced by induced cells of human origin, a waterinsolubilized sulfated polysaccharide/interferon adsorbate and then selectively eluting the interferon with an aqueous solution of an inorganic salt. 
     The water-insolubilized sulfated polysaccharide/interferon adsorbate may be formed either by contacting the solution containing interferon with a water-insolubilized sulfated polysaccharide or alternatively by contacting the solution containing interferon with a sulfated polysaccharide to form a sulfated polysaccharide/ interferon adsorbate and then contacting the sulfated polysaccharide/ interferon adsorbate with a carrier capable of rendering the sulfated polysaccharide water-insoluble.

Abstract: A hand labeller having a plurality of rotatable print wheels with selectable print types disposed on the periphery of each print wheel and a selector spindle for positioning selected print types at a printing zone of the print wheels. The selector spindle includes a reduced diameter portion which engages and slides in an arcuate slot in the labeller housing if (a) the spindle is fully pushed into the print wheels and (b) the labeller is operated to rotate the print zone of the print wheels to a label printing position. If the spindle is not fully pushed in, a large diameter portion of the spindle will engage the arcuate slot, the latter portion being too large to enter the slot whereby the print zone of the print wheels is inhibited from rotation to the label printing position.

Abstract: A process for producing frozen potato strips from raw potato strips which process comprises circulating humid hot air over the surfaces of the raw potato strips in unblanched condition until the strips are partially gelatinized and partially dehydrated substantially throughout and their weight is reduced to 85% to 90% of their raw weight, circulating substantially dry hot air over the surfaces of the strips until the strips are further partially dehydrated and their weight is 75% to 80% of their raw weight, and thereafter freezing the strips for storage without the strips having been blanched. 
     Optionally, the strips may be partially-fried after being dehydrated and prior to being frozen. The potato strips are prepared quickly and effectively for frozen storage, while conserving energy and maintaining the texture, flavour and odor of the finally fried potato strips comparable to potato strips which have been deep fat fried without having been frozen.

Abstract: The invention relates to a crane of the type which is transportable to the job site, is adaptable for making very heavy lifts and may be operated as a mobile or stationary crane. The crane includes the crane body, the rearward end of which is arranged to be transported on the highway on a trailer which can subsequently be used as an auxiliary counterweight. The front end of the crane body is adapted for connection to and support on a conventional truck tractor. The overall dimensions of the crane body are such that it may be transported on the highway from job location to job location and there assembled and subsequently disassembled. The crane body has an outrigger support body rotatably positioned therebelow which is adapted for the attachment of outriggers. In operation the outriggers can be used to raise and lower the crane body to remove the trailer and the truck from the crane body, such that the crane may be supported on the outriggers. The crane may have an extendable bridge attached to the trailer, with the trailer having its longitudinal axis transverse to the crane body to swing therewith. In certain embodiments the outriggers may be supported on contra rotatable crawlers to thus provide a fully mobile crane. Another crawler means may be added to support the forward end of the crane body, thereby providing a swinging outrigger for assisting in the rotation of the crane body. The crane of this invention is also adapted for use as a guy derrick or a tower crane, and in other configurations, as described hereinafter.

Abstract: A conveyor belt 13 of stretchable elastomeric material reinforced by layers of cords which permit an initial stretching of the belt at installation of at least 5 percent. Reinforcing cords 32, 33, 43, 45, 49 are positioned in the belt elastomeric material to generate transverse forces during the stretching of the belt which results in the interaction of the material of the belt with the cords. This interaction causes the edge portions 29, 30 of the belt to curl upwardly and form load-retaining walls at the edges. The belt may have a bottom stretchable portion which is reinforced to resist outside transverse forces resulting from the passage of the belt around a curve. A top stretchable portion of the belt has edge portions which bend upwardly to form the load-retaining walls. The edge portions of the belt may curl sufficiently to bring the edges together and they may be connected for enclosing the load on the belt surface.
