IPC: G05D3/12

Abstract: 1,231,807. Measuring heading electrically. S. G. BROWN Ltd. Nov.4, 1968 [Nov. 6, 1967], No.50423/67. Heading G1N. Apparatus for transmitting azimuth angle from a gyro compass 3 to a remote heading indicator 5 comprises transmitting and receiving rotary potentiometers 10, 20 with first pairs of diametrally opposed contact brushes 15, 16 and 25, 26 respectively supplied with equal energizing voltages from direct current sources 30, 38, which potentiometers are tapped at three points 12, 13, 14 and 22, 23, 24 respectively, the points being spaced apart by 120 degrees, respective pairs of points being connected by transmission lines 32, 33, 34. As shown contact brushes 15, 16 are set to a required angle by a mechanical connection 17 to the gyro compass thus the supply potential is distributed in a way which is reproduced exactly in the receiver potentiometer since the brushes 25, 26 are at angular positions with respect to the tapping points identical with those in the transmitter potential. Therefore a second pair of contact brushes 27, 28 carried on the rotor 29 of the receiver potentiometer for mutual rotation with the first pair and opposed diametrally orthogonally of them will sense no potential difference. However when the transmitter brushes are rotated by the compass a potential difference will be sensed by the second brushes 27, 28 (potential differences are established between like points on the two potentiometers causing currents to flow in the transmission lines thereby modifying the potential distribution). The sensed error voltage activates a servo loop 44-50 of which the motor 50 drives the rotor 29 to bring brushes 27, 28 to the voltage null position. The angular displacement is transmitted via gearing 55 to heading indicator 5.

Abstract: 1,231,834. Moulded boxes. GIROPOR. 7 Nov., 1968 [8 Nov., 1967], No. 52755/68. Heading B8P. A stackable container of moulded expanded plastics, such as foamed polystyrene, is provided with inwardly directed flanges 7 at upper edges of side walls 1 and reinforcing fillets 5 and 8 at the internal corners of the base 2 and side walls and of the flanges and side walls to resist buckling of the side walls when a plurality of like containers are stacked. As shown, two opposed side walls are provided with said flanges which are grooved at 9 to receive a sliding lid 6. In a similar embodiment, Fig. 11 (not shown), a third wall is provided with an inwardly directed flange. In another embodiment, Fig. 2 (not shown), the grooves are omitted and a flat lid may be provided. In further embodiments, Figs. 5, 8, 9 and 10 (not shown), the edges of the flanges, which may extend along two side walls or around all four walls, are outwardly chamfered to receive a drop-on lid 6 having corresponding chamfered edges 16. Where the flanges are provided only on the two opposed walls, projecting lugs 18 on the edges of the lid locate in recesses 17 formed in the flanges, Fig. 9. Drain holes 13, Figs. 7 and 11 (not shown), may be provided. The containers are moulded using moulding equipment comprising components 11 and 12, component 11 being profiled to form the flange and fillets of the side walls, Figs. 6 and 7 (not shown). When pairs of containers are stacked, Fig. 12 (not shown), the strengthened flanges and bottom corners form a composited strengthening beam in the stack.

Abstract: 1,232,307. Ferric chloride production. BADISCHE ANILIN- & SODA - FABRIK A.G. 11 Sept., 1968 [12 Sept., 1967], No. 43107/68. Heading C1A. Anhydrous ferric chloride is made by continuously feeding particulate materials containing metallic iron, e.g. scrap iron, into a chlorination zone at elevated temperature at a rate such that the height of the layer of material in the reaction zone above a point of introduction of the chlorine is kept as constant as possible within the range from 10 to 40 ems., the chlorine being fed at a predetermined constant rate. The bed height (and thus the reaction) is controlled by regulation of the addition of scrap with reference to either (a) the offgas temperature, or (b) the chlorine content of the offgas (which may contain an inert gas, e.g. N 2 ). In the Figure, 1 is a bin containing scrap iron, which with kiln 2 forms a system which is sealed against the outside atmosphere. Metering of the scrap iron feed to the reaction zone is carried out by an electromagnetically operated vibrating conveyer 3. Chlorine is introduced via inlets 4, into the kiln, optionally mixed with an inert gas. Offgas with vaporous FeCl 3  escapes via outlet 5 to condensers (not shown) to condense FeCl 3 . Hot scrap iron is supplied via pipe 6 when starting the kiln from scratch.

Provision may be made for the injection of an antioxidant oil downstream of the point of entry of sulphuric acid. The rate at which water, sulphuric acid, and antioxidant oil are added may be controlled according to the weight of lead oxide added.

Headings D1C and DIE..[Also in Division F2] To maintain constant warp tension a pivoted back rest operates a hydraulic or pneumatic disc brake geared to a warp beam &c. A lever 30 is adjustably loaded by a spring 35 to act on the back rest (not shown) and tension the warp. The spring surrounds a rod 32 which is pivoted on a bell crank lever 40 having a spring loaded rod 41 and a lever 47 acting on a brake master cylinder 48 which operates a disc brake 52 controlling the let-off by wayof gears 64, 22. In use the initial warp tension is set by adjusting the spring 35 and the brake pressure by adjusting the spring 43 surrounding the rod 41. The linkage is then such-that as warp tension increases brake pressure is relieved and vice-versa.

Abstract: 1,233,784. Activated carbon. SHIN-ETSU CHEMICAL CO. 18 Sept., 1968 [22 Sept., 1967], No. 44415/68. Heading C1A. Activated carbon is made by dry distilling at a temperature of 400-750‹ C. a cellulosic vegetable material such as rice shell, hull bran, nut shells, cotton seed hulls, chipped wood, wood shavings and sawdust, separating the powdery carbon from the gaseous distillate and then passing it, without cooling, into an activation apparatus. The carbon is activated with steam which is passed through the carbon along with an O 2 -containing gas which burns part of the carbon and maintains the temperature in the range 900-1100‹ C. The gases issuing from the distillation and activation steps are burnt in a heat exchanger, thereby generating steam for the activation step, and the hot gases are then introduced into the dry distillation. The raw material is preferably dried to a water content of less than 10% wt. A part of the combustion gases from the activation stage and/or O 2 -containing gas may be introduced into the dry distillation step. Various physical properties of the activated carbon are specified.

Abstract: 1,250,868. Thermoelectric devices. SIEMENS A.G. 11 June, 1970 [25 July, 1969], No. 28410/70. Heading H1K. A plurality of thermo-elements located in respective apertures in a thermally insulating plate are connected together by hot and cold junction bridges having heat transference projections which engage respective frame members to define heat transfer fluid ducts and to apply pressure to the bridge-thermo-element contacts. The contacts may be effected merely by the pressure or may be soldered in addition. As shown, Fig. 1, an insulating plate 1 of hard polyurethane foam is provided with a plurality of countersunk apertures 2 within each of which is located a thermo-element 3. The thermoelements are connected in series by hot and cold bridge members 4, each of which comprises a base member 4a having projections 4c which enter the apertures 2 and contact the thermoelements 3, and fins 4b. Two U-shaped frame members 5, 6 are secured to the plate 1 by rivets 7 and are lined with elastic foam layers 8 which are deformed by and hence apply pressure to the ends of the fins 4b, thus holding the ends of the projections 4c against the thermo-elements 3.
