Abstract: 1. Process for producing poisoned bait, especially for rodents, in which the toxic liquid substance is introduced into comestible grains serving as support, characterized in that the following operations are combined : a) an important expansion of the grains is realised by heating in presence of a paraffine accepted by the rodents, following a mode of operation already known for maize (popcorn), which multiplies the volume about 10 to 20 fold and allows to obtain a density notably lower than 1, the quantity of the paraffine being about the half of the weight of the grains ; b) a homogenous mixture is produced, comprising substantially a comestible oil, especially a well digestible vegetable oil, 2 to 3% of the mixture of colorants and less than 1% of toxic products, whereby care is taken that the temperature does not raise above room temperature ; c) the products obtained in step a) and b) are agitated at room temperature in a mixer until the homogenous toxic mixture has penetrated suitably into the grains, which is determined by the coloration of the expanded grains ; d) the grains obtained in step c) are coated with a first coating, said of concentration, of a layer of an impermeabilising substance, which is accepted by the rodents and is not colored, as microcrystallizable waxes or paraffines, melting at temperatures of about 60 degrees to 65 degrees and crystallizing slowly at cooling, by pouring this substance melted just above the melting temperature over the grains beeing agitated in a kneading machine, the weight of the coating substance representing 45% of the weight of the treated grains, the kneading beeing continued until the superficial crystallization prevents the agglomeration of the grains ; e) the grains obtained in step d) are coated with a second coating, said of isolation, of a second layer of a colored impermeable substance, optionally beeing different of the first layer, accepted by the rodents, crystallizable, melting at a temperature of about 60 to 65 degrees, by pouring the said substance, melted at a temperature slightly above the melting temperature, over the grains agitated in a kneading machine, the kneading beeing continued until the superficial crystallization prevents the agglomeration of the grains, the proportion of the coating substance in step e) beeing about twice the weight of the grains, so that in total a bait is produced, which has about 4 to 5 times the weight of the initial grains contained in it, but having a density of about 0.25 ; f) the crystallization of the coating of the grains is allowed to complete by controlling the penetration of the coatings into test grains by examining the colored layers.

Abstract: To obtain castings having areas with improved wear resistance, substances which cause with the melt a local alloy effect are introduced in the mould. A base metal is used which is comprised of manganese austenitic steel and porous bodies of ferroboron. To this effect, the finally divided ferroboron is mixed with an aqueous solution of alkaline silicate and optionally with other hard materials, and the mixture is foamed by heating preferably in core boxes, and the hardened bodies are introduced in the mould areas where they are to cause a local alloy effect. The use of such hard castings for bucket tip s and/or edges of power shovels has given very good results.

Abstract: The cooling zone (K.Z.) pertains to a furnace, preferably a roller furnace, comprising a preheating zone (V.Z.), a firing zone (B.Z.) and a cooling zone (K.Z.). The articles to be fired, preferably ceramic slabs or plates, are conveyed through that furnace, in one layer without refractory material support. The zone (K.Z.) is indirectly cooled in order to prevent, in this zone (K.Z.) and its neighbourings, the atmosphere from acting on the articles to be treated, thereby avoiding a re-oxidation of said articles (B), and it is possible to act on their outer surface in a simple manner by means of a heat-carrying flow, preferably a heat-conveying fluid. The cooling zone comprises members which are adjustable in direction and flow rate for injecting materials acting on the surface of the articles. The indirect cooling is achieved preferably by means of coils (3) arranged above the articles to be subjected to the firing (B); their radiating surfaces may be masked in an adjustable fashion (in 5) and are arranged transversely with respect to the direction of movement of the articles. The masking elements (5) may be pivoted to swing like the blades of a blind or be made of sliding plates, movable towards each other. The coils (3) may be connected with other parts of the furnace, or with heat recovery installations.

Abstract: A radially inward flow turbine has an annular nozzle arrangement (25) through which pressurized gas is passed in a generally radially inward direction from an annular inlet passage (24) to a bladed turbine wheel (16). The nozzle arrangement (25) is defined by parts (26, 28) of the turbine housing (10) which are relatively displaceable axially of the turbine for varying the dimensions of the nozzle arrangement (25) and hence for varying the turbine air pressure ratio. In orderto enablethe dimensions of the nozzle arrangement (25) to be varied without problems of seizure of the relatively displaceable parts, the latter parts are in the form of relatively displaceable rings (26,28) which each carry a respective annular array of angularly spaced vanes (36, 34) for directing the gas flow from the annular inlet passage (24) onto the turbine blades (20). The angular positions of the vanes (36, 34) on the rings (26. 28) are such that the vanes (34) on the ring (28) are interposed with the vanes (36) on the ring (26). Relative axial displacement of the rings (26, 28) varies the extent of axial overlap of the vanes (36,34) when they are in their interposed state.

Abstract: The screw extruder for processing at least two different polymer materials has the purpose of achieving a marbled effect on the basis of a mixture of these polymer materials on a finished plastics part. The screw extruder has two mutually separate screw sections (5,6), lying axially one behind the other, which are in each case connected to a feed opening (9 and 10, respectively) provided in the barrel (1) of the extruder and can be fed with polymer material through the said opening. The screw channel (7) in the front screw section (5) is connected directly to a converting point for the polymer materials ahead of the screw tip; the screw channel (8) in the rear screw section (6) is connected to this converging point via openings (14) in the screw (2), which lead from the rear screw section (6) to a hollow bore (15) made in the front screw section (5). This hollow bore (15) opens out at the screw tip. Consequently, there is a complete separation of the polymer materials different in their colour and/or properties until the converting point, so that the time available before discharging through the die (3) of the barrel (1) is not sufficient for mixing and consequently the mixture required for the marbling effect is obtained. <IMAGE>

Abstract: A current source circuit is arranged so as to provide a low-level current on the order of 0.1 microampere at a high level of accuracy. A series connection of first and second transistors (Q1, Q2), each having its base shunted to its collector, is connected between first and second power supply terminals (11, 12) so as to be supplied with a first given input current (I). The collector-emitter path of a third transistor (Q3) and a resistor (14) connected to the emitter of the third transistor (Q3) are connected between the first and second power supply terminals (11, 12) so as to be supplied with a second input current (nl) the magnitude of which is n times that of the first input current. The base of the third transistor is connected to a current supply terminal of the series connection of the first and second transistors. A fourth transistor (output transistor (Q4)) has its base-to-emitter junction connected between the resistor (14) and the second power supply terminal (12), to provide its collector with an output current (lo). Since the base-to-emitter voltage of the output transistor is reduced by a voltage drop across the resistor, the output current can be made small.

The valve body has a flat valve seat having thereon a diaphragm with a valve shutting part. In the seat there are valve openings, each having a number of concentric ring-like channels round it in the seat. The concentric channels take up a sealant, more specially silicone oil. The diaphragm is made of a single piece of material running on one side of the walls to the other without any holes therein. It is only kept in position in a middle part of the valve seat so that the diaphragm may be moved freely, at least over the valve openings. In the case of a preferred form of the invention, the diaphragm is slipped loosely into the valve body in which it is kept in position by a keeper in a middle part thereof. The keeper may be fixed in position by friction or by a keying effect.

Abstract: A composite thermal insulation panel for a metal processing installation has a thin-walled casing providing a membrane (8 or 116) that will be heated quickly to near the temperature of an adjacent hot metal slab or strip (M) being processed and said membrane has means to allow substantial freedom for movement relative to adjoining regions of the casing due to thermal expansion caused by the large temperature changes. These means may include retaining elements (38 or 44, 48 or 44, 54) of the casing that locate the membrane transversely to its extent but permit relative movement in its own plane, or they may include the provision of surfaces (81) that slope to a central region to accommodate relative thermal expansion by flexure. Panels below the material path may have membrane surfaces that slope downwards to an escape aperture (118 or 166) for scale dropping from the hot metal. Panels above the material path may have apertures (146) aligning with the lower panel apertures for temperature sensors (148) that detect the passage of hoat material between the panels.
