Title: Method of and apparatus for cooling annealed material
IPC: C21D1/84
Filed: 1964-01-10
Abstract: <PICT:0985768/C6-C7/1> In a process and apparatus for cooling material in a vacuum chamber by means of a flow of protective gas, a stream of cold gas is mixed with the hot gas leaving the chamber to reduce the temperature of the latter gas before it reaches the outlet valve. The added gas may be identical with the main cooling gas, in which case the mixture may be recirculated. Preferably the additional flow of gas is controlled in accordance with the temperature of the gas leaving the vacuum chamber.  As illustrated, charge 2 in vacuum chamber 1 is cooled by passing in cold gas through valve 3, the heated gas leaving through conduit 7 and valve 21.  A part of the cold gas flow, controlled by valve 15, is by-passed through conduit 23 to mixing nozzle 19 where it surrounds tube 20, partially cooling the hot effluent gas by conduction and then mixing with it.  The flow of gas through valve 15 may be automatically reduced as the temperature of the hot gas falls, until that temperature reaches the permissible operating temperature of valve 21, when valve 15 is completely closed.  A recirculator and cooler unit indicated generally at 5 is detachable from the vacuum chamber circuit at 24, 25, and is thereby usable with a plurality of vacuum chambers.

Title: Improvements in and relating to dish washing machines
Inventor: ALABASTER ARTHUR JAMES
IPC: A47L15/16
Filed: 1960-01-13
Abstract: 894,310. Dish-washing machines. COLSTON Ltd., CHARLES. Dec. 2, 1950 [Jan. 13, 1960; Feb. 18, 1960], Nos. 1311/60 and 5854/60. Class 138 (1). In a dish-washing machine having a washing chamber through or within which washing liquid is caused to circulate continuously the washing liquid is filtered by a main filter through which all or the greater part of the circulating liquid passes and a secondary filter or filters of finer mesh through which only a part of the circulating liquid is permitted or constrained to pass. As illustrated in Fig. 1 the dish-washing machine has a rotary impeller as described in Specification 832,756 for discharging spray on to the dishes to be washed, which are arranged in racks R 1 , R 2  in a cabinet C. The main filter (not shown) consists of a disc of open mesh gauze detachably fitted in the sump S, and the secondary filter F is suspended between a side runner for the rack R 2  and the cabinet wall. The filter F consists of a bag or pouch of fine mesh, e.g. of nylon, attached to a wire frame the upper parallel members 3, 4 of which are more widely spaced than the lower members 5 to provide an open mouth to collect the soiled water running down the cabinet wall. The lower part of the bag is held away from the cabinet wall by a member 7 so that the filtered liquid passes through both walls of the bag. To prevent overspilling caused by foam present in the washing liquid the filter bag may have a narrow throat near its mouth. Alternatively a bimetallic element may be disposed in the mouth of the filter bag which flexes as the temperature of the washing liquid rises during the washing operation to reduce the size of the mouth opening. Overspilling of foam may also be prevented by alternately inclined baffles arranged in the filter bag. In two further constructions the secondary filter is arranged opposite one end of the impeller tube T, and above the main filter in the sump S, respectively.

In the first case, the lever 8 may be mounted as shown in Fig. 1, or it may be mounted directly on the joint 6 or on the axle 7, a ball joint being provided between the members 8, 5 in the last instance. In the construction shown in Figs. 1 and 3, the braking action is unaffected by the steering movement of the wheels, since the point of action 9 of the control lever is not appreciably displaced during steering. When, as shown in Fig. 5, the point of action 9 is located between the joints 6. 4. the steering of the wheels will increase the braking action on the inner wheel and diminish that on the outer wheel, whereas, when, as shown in Fig. 6, the point of action 9 is located between the joint 6 and the centre line of the vehicle, the braking action of the inner wheel is diminished and that of the outer wheel is increased during steering. In the constrution shown in Fig. 5, the point of action 9 is so located that the couples to which the steering-swivel is subjected by the traction of the control lever and the resistance of the braked wheel are balanced.

Title: Diffusing device

Abstract: 823,498. Diffusing devices. SOC. POITEVINE DE CONDITIONNEMENT. Jan. 15, 1958 [Jan. 30, 1957], No. 1476/58. Class 81 (1). A diffusing device comprises in combination, a mass containing a volatilizable substance and an envelope which hermetically encloses the mass, the mass being provided with a plurality of channels in the space between opposite portions of the inner surface of the envelope, whereby upon the envelope the ends of the channels are placed in communication with the atmosphere thereby permitting circulation of air in contact with the mass. The channels may be either depressions provided on the surface of the mass or on the inner surface of the envelope itself, or they may pass through the inside of the mass, and a combination of all three may be used if desired. As shown, the envelope is composed of two sheets 1, 2 of flexible plastic or laminated metal foil and plastic materials sealed at their edges and containing a mass 11 of active substance in solid, paste or gelatinous form capable of diffusing into the atmosphere as the result of evaporation and/or sublimation. Between the inner faces of the sheets 1 and 2 and the outer faces of the mass 11, there are provided linear grooves extending across the mass thus increasing the surface of the mass exposed to the air. At three of the original corners score marks are provided along which the sheets may be torn to remove the comers to allow the free space between the sheets to be opened to the atmosphere, the fourth corner being used to hang the device. Instead of a single tablet, several flat pieces of active material which are sufficiently large so as not to escape through the openings resulting from the removal of the corners may be used and they may be traversed by inner channels for the circulation of air. The inner faces of the bag or envelope may itself be provided with depressions, for instance, by the use of ribbed or corrugated sheets 1 and 2. An absorbent strip, e.g. of blotting paper 13 is provided adjacent both sides of the mass to retain any condensation liquid. The mass may include an active ingredient consisting of or comprising one or more insecticides or insect repellants such as dichlorodiphenyltrichlorethane, hexachlorocyclohexane, phosphoric and thiophosphoric esters, urethanes. Specification 710,881 is referred to.

Animal traps. - In a noose trap wherein a spring barrel rotatably scoured to the ground is used for tightening the noose, this noose is carried on a tubular arm or guide member through which the draw-string of the noose passes to the spring barrel, this tubular arm being arranged at either end to hold the spring barrel in the set position. The spring barrel 9 rotates upon a hollow shaft 10 carried on the casing bottom 11 and pivotally secured to the ground by a pin 23. A spring 12 is attached at either end to the shaft 10 and barrel 9. The noose 14 passes down a tubular arm 17, through an opening 16 in the casing 11 and is fixed to the barrel 9 at 15, the arm 17 being mounted in a bracket 19 pivoted on a bolt 18 on the casing 11 and having an end 20 which passes through a cut-away portion 22 of the cover 13 and engages in a cut-away part 21 of the barrel 9. To set the trap the loop or running noose 14 is drawn out until the end 20 can be depressed into the notch 22 and upon an animal entering the noose, the arm 17 is depressed to release the spring barrel which winds in the noose. The trap may be locked set by a pin 24 and holes 26, 27 in the bracket 19 and casing 11 respectively. Stops 28, 29 limit the barrel 9 to one rotation. In a modification, Fig. 6, the wire is wrapped twice round the spring barrel 30 and to permit of two rotations of this barrel an arm 46 loose on the central hollow shaft 31 co-operates with two stops 45 on the top of the spring barrel 30 and a stop 47 on the underside of the cover 34. In a further modification, Fig. 8, instead of the end of the bracket 19 engaging the spring barrel, a stop 50 on the noose engages a constricted part at the outer end of the arm 51.
