Abstract: An igniter device for a gas lamp of the type having a main mantle burner and a main control valve operated by a control lever, is provided with an auxiliary valve controlling the gas flow to an auxiliary burner the flame from which is directed onto the mantle to ignite this when fed with gas. The main control lever is connected to a piezo-electric spark generator which is operated by the lever to generate sparks as the main valve is moved to a fully open position. The auxiliary valve is also linked to the main control lever so as to be opened just as or just before the piezo-electric spark generator is operated whereby ignition of the auxiliary burner and hence the main burner is effected by the single operation of the main control lever to fully open the main flow control valve. The construction includes means for ensuring that the auxiliary valve is closed when the main control lever is released.

Abstract: A flexible hose having resistance to radial crush is formed from a bonded and interlocked helically wound rod or strip of plastic co-extrusion. The co-extruded profile of the strip is defined by a pair of matable rib components which are joined by a web. The rib components are bonded, sealed and interlocked together at adjoining convolutions of the profile not only to form the hose but also to form a composite rib integrated into the hose for resisting radial crushing and axially directed deformation forces exerted on the hose. The composite rib is formed from a material having a hardness which is greater than that of at least a part of the web for rendering the rib with a relatively stiff bend resistance characteristic and the web with a relatively soft and flexible characteristic. The web itself may be a co-extrusion of two materials placed in series, or in parallel as a laminate, or a combination thereof. If a laminate, one of its materials may be the same as that of the rib but much thinner so as to provide a larger surface area for greater bonding or adhesion among the several parts of the extruded profile. Different materials, especially in a laminate, enable the hose to be tailored for specific uses and environments which come into contact with either or both the inside and outside of the hose.

Abstract: When foundation plates for buildings are cast on site, a cavity is delimited by means of so-called plinth elements 6 of known configuration, which are designed to be cast in place, and which comprise a plate 7 partially enclosed by a stiffening layer and made of porous heat-insulating material. During the casting, the plinth elements are fixed to outside stays 4, 5 by means of lashing wires 11 attached to the plinth elements by means of holders 10, which holders are hooked to the inner sides of the plinth elements and simultaneously serve to bear a reinforcing iron 13 intended for embedment and forming an uppermost outer edge reinforcement in the foundation plate. Following completion of the casting operation, these holders 10 and the reinforcing iron which they bear help to anchor the plinth elements firmly to the foundation plate. A configuration of the holders 10 which is appropriate to the aim is also indicated. <IMAGE>

Abstract: Installation removes solid particles from the water circulating system of a cooling tower. Water and sediment are pumped from the circulating system collection tank to a screw which passes water to be treated into a first settling tank. Water is pumped from the bottom of the first tank to a first hydrocyclone separator which delivers water back to a second settling tank. Water is pumped from the bottom of the second tank to a second hydrocyclone separator which returns water to a third settling tank. Water is pumped from the third tank to a third hydrocyclone separator which makes fully treated water available for return to the cooling tower circulation system. The first hydrocyclone separator pref. removes all particles above 74 microns. The second separator pref. passes liq. from which 95 percent of the sand and mud received from the first separator is removed. Water discharged by the third hydrocyclone separator is pref. passed to a holding tank from which it is pumped back to the cooling tower system. The installation is used to remove sand, silt etc. from the circulating water tank of a cooling tower. Sepn. can be extended to achieve any required degree of clarity. The installation is efficient, robust and very easy to operate and maintain, including no moving parts except in pumps.

Abstract: The shell is removed from a crustacean by creating a pressure difference across the shell. Initially the crustacean is heated until body liquid adjacent the shell is just below boiling point. The pressure on the crustacean is then suddenly lowered to induce the liquid to boil and thereby create the pressure difference across the shell. After pressure treatment, the crustaceans are projected into a liquid bath which completes the shell removal by mechanical abrasion in the liquid. Method removes the shells from shrimps and krill. Shell removal efficiency approaches 100 per cent.

A periphery of the rotating grinding wheel constitutes the sharpening surface for grinding the hard-metal stud on the studded crown, with the grinding wheel being supported to rotate about its own axis and swivel with respect to the stud to be sharpened, such that the circular or swiveling motion of the rotating grinding wheel takes place about a swiveling axis passing through the stud to be sharpened. The shape of the sharpening periphery of the grinding wheel may be advantageously fluted or curved such that the periphery itself forms a substantially circular arc, whereby the combined rotational and swiveling motion of the grinding wheel produces a substantially hemispherical shape on the hard-metal stud being sharpened.
