Abstract: 1,149,579. Forming packages. NATIONAL DAIRY PRODUCTS CORP. 13 Dec., 1967, No. 56665/67. Heading B8C. [Also in Division A2] Portion controlled food units are made by freezing a sheet of food material and forming in it grooves allowing the sheet to be broken into units. In the example given, a predetermined amount of material is placed in a flexible plastics bag, and after the bag has been evacuated and sealed, the package is flattened to a desired thickness and frozen. The grooves, or score lines, are then made by pressing the package between shaped dies. Ribs on the dies are preferably rounded to avoid cutting the bag, or alternatively one rib may be sharpened so that one wall of the bag is severed and the food units can easily be removed. Examples of food materials given are sandwich fillings, meat and ice cream.

A passive-tank ship stabilizer comprises an elongated tank partially filled with liquid and so constructed or mounted that the ends thereof are capable of changing position relative to the ship, whereby when liquid impinges upon an end, the end is caused to move outwardly and thereby increase the stabilizing moment applied to the ship. In Fig. 7 the tank 22 is movable as a whole. The tank 22 is in the form of a rectangular box mounted on rollers 40 for movement in a housing 20 fixed athwartship when stabilizing roll. The movement of the tank is resisted by springs 46 and is guided by tracks 42 for the rollers 40 and by bumpers (44), 45. In Fig. 14 the tank 22 as a whole is fixed but the ends 126 are in the form of pistons movable by the liquid against springs 128. To dampen the liquid movement fore-and-aft rows of upstanding members 32 are arranged in the tank, Figs. 3 and 15 (not shown), to provide constrictions therebetween, the members being of various cross-section Figs. 5 and 13 (not shown).

Abstract: 1,244,542. Zone-melting apparatus. COMMISSARIAT A. L'ENERGIE ATOMIQUE. 25 Nov., 1969 [18 Dec., 1968], No. 57613/69. Heading BIS. Zone-melting is effected in a longitudinally elongated container (not shown) displaceable along its longitudinal axis between two ovens 12, 14 each provided with means for regulating the temperature of the material located within the oven at a predetermined value, respectively close to (oven 12) or above (oven 14) the point of change of phase, the oven 14 being located upstream of the oven 12 in the direction of movement of the container and being of higher heating power and thermal inertia than the oven 12. Oven 14 is displaceable along the said axis relative to oven 12 in response to a regulator means for maintaining constant the temperature gradient in the liquid phase in proximity to the solidliquid interface. As shown, oven 14 is displaced via rotatable screwed rods 17 controlled by gears 20 and motor 18. Both the ovens fit concentrically over the container, which is held at one end in a cooled heat-sink 16, itself attached to a screw-rod moving device 38, 40, 42. Temperature regulation may be effected using a thermocouple at each end of the container each differentially connected with a centrally-located thermocouple. The outputs from these are fed via electronic devices to control the power input to oven 12 and the position of oven 14. Regulation may be such that the maximum temperature in the melt is displaced away from the mid-plane of oven 14 towards oven 12. The ovens may be resistance heated, or may act through electric induction in the material being treated.

[Also in Divisions G1, H1 and H3] In an ionization chamber detection apparatus in which two series connected ionization chambers 13, 14 (see Division H1) and an F.E.T. amplifier 11 are powered from the same low voltage supply 3 (10 v.-35 v.), the voltage at point 12 between the two ionization chambers 13, 14, one of which 14 is sensitive to the presence of smoke in the atmosphere e.g. from a fire and the other 13 is closed to the atmosphere, is applied to the control electrodes 18, 19 of F.E.T. 11. The F.E.T. 11 is arranged to be non- conductive in the absence of smoke but when the voltage at point 12 changes, due to the presence of smoke, the F.E.T. 11 conducts completing the power supply to unijunction transistor oscillator 9. Firing pulses are thus applied to the gate 8 of a Triac 7 over transformer 10 to cause the Triac to conduct and energize an audible alarm 6.

Abstract: 1397070 Electrically conducting silicon nitride UNITED KINGDOM ATOMIC ENERGY AUTHORITY 29 Nov 1972 [16 Dec 1971] 58381/71 Heading C1A A silicon nitride artefact is heated to a temperature high enough to decompose part of the nitride to silicon but not high enough to evaporate the silicon formed, the heating taking place in an environment inert to silicon or in a carbon containing environment to convert the silicon to silicon carbide, thus giving an artefact bonded by silicon nitride having an electrically conducting phase of silicon or silicon carbide. The heating may be at a temperature in the range 1350‹ to 1550‹ C. In order to prevent oxidation of surface silicon, it may be nitrided. The carbon containing environment may be elemental carbon, combined carbon in a decomposable form such as sugar, a wax or a hydrocarbon oil or a gas such as methane. To ensure a non-oxidizing environment the heating may be conducted in the presence of argon or helium, or in the presence of nitrogen at temperatures above 1500‹ C.

A method of heat treating formed products in a vertical kiln comprises establishing two bodies of hot gas rotating in opposite directions in rolling contact with each other about parallel vertical axes, the individual molecules in each body of gas flowing in a helical path around said axes, while simultaneously moving the formed products up between said axes in the region of rolling gaseous contact. A kiln in which the method is performed includes a vertical shaft 3 divided into intersecting chambers 4, 5, tangential inlet ducts 6 introducing air into the top of each chamber in opposite directions, tangential inlet ducts 8 for injecting a combustible fluid in the centre of said chambers, an exhaust fan 7 for removing gaseous products of combustion tangentially from the base of said chambers, and an hydraulic jack 9 for moving a series of batts 10 holding the formed product to be fired up through the kiln. In operation, a support 10 comprising an aluminium oxide or silicon carbide batt carrying an unfired grinding wheel 11 is placed on a loading conveyer 20, support blocks 22 being located at the corners of the batt to provide spacing. The loaded batt is rolled from the conveyer into position over the head of hydraulic jack 9 and the jack actuated, a treated or fired grinding wheel and its batt thus being lifted above the top of the kiln. A rotating arm 15, rotated into position over an unloading conveyer 21, is lowered by mechanism 16 to remove the said uppermost loaded batt.

This is achieved by growing the layer 11 from the liquid phase on to a semiconductor substrate and then growing the support 12 on the exposed surface of the layer. The substrate is then removed by mechanical abrasion and/or chemical etching either entirely or, as shown, to leave selected regions 10. In an embodiment the starting substrate is gallium arsenide, the grown layer is of gallium aluminium arsenide, and the grown support is of gallium arsenide. The process may be used to make an electroluminescent structure, a PN junction being formed between the layer 11 and its support 12 or being formed within layer 11 either by diffusion into the face exposed before growth of the support 12 or by diffusion into the free face provided after removal of the starting substrate.

In the form shown in Fig. 1, doors 22, 23 are held closed by catch-bolts 12, 13 having rollers 14, 15 engaging suitably ramped keepers 16, 17 and are held down in the fastening position by an electromagnet 2 acting through links 4, 5 and bell-crank levers 6, 7 engaging abutments 10, 11 on the respective bolts. The electromagnet may be de-energised by either of N.C. switches 26, 27 which are opened by shooting mechanically operated bolts 18, 19, or by either of the N.O. limit switches 30, 31 which detect when the respective door is closed. The inclination of the catch ramps may be such that the holding force of the magnet may be overcome in a panic. Normally the doors are released from a distance by cutting off the current. It is shown in Fig. 8 how a single lock 20 and magnet 2 may control bolts at top and bottom of the door through a linkage 4-9. A similar result may be achieved by connecting the floor bolts to the bolts shown in Fig. 1 by a direct link (Fig. 1 bis, not shown). Indicators and alarms may be incorporated in the circuit. The electromagnet may act directly on the door and its armature co - operate directly with the striker ramp so that it is lifted against gravity as the door is opened.
