Abstract: 1,238,935. Draught control system. PILKINGTON BROS. Ltd., C. INMAN, and D. G. CADWELL. 13 June, 1969 [18 June, 1968] No. 29036/68. Heading F4B. Chimney draught is controlled by directing a stream of air centrally downwards into the chimney and deflecting gases rising adjacent the chimney wall towards the centre of the chimney to produce a recirculation of the chimney gases. In a chimney 21 leading from a recuperator 22 in the waste gas off-take of a glass furnace 19, a nozzle directs air downwardly at the centre of the chimney top. An inturned lip on the chimney deflects the rising gases inwardly, and the air delivered from a fan 24 is controlled in accordance with the pressure above the glass in the furnace. A sensor 29 compensates for changes in the ambient atmospheric pressure. The top of the chimney may be surrounded by a wind shield, and the nozzle may be spaced from the plane of the chimney top so long as the stream of control air penetrates beyond the lip at the chimney top.

Abstract: 1,250,202. Heated windows. COMPAGNIE DE SAINT-GOBAIN. 13 Nov., 1968 [13 Nov., 1967], No. 53780/68. Addition to 1,145,367. Heading H5H. [Also in Division C7] After firing the silver resistance bands to the glass sheet as in the parent Specification, the total resistance of the bands on the blank is measured and used to determine how much metal needs to be electro-deposited thereon to bring the total resistance to the desired value. The electrodeposited metal is copper, and it may be protected by a further electrodeposited layer of nickel, the amount of nickel needed being determined by measuring the resistance of the copper electrodeposited blank. The time of the electrodeposition or the current strength used in deposition may be used to determine the final resistance. In one example a plurality of blanks are electroplated in the same bath, each blank being supplied through a separate resistance from a rectifier and controlled by a device which switches off the current to all the blanks simultaneously after the time necessary for them to acquire the desired resistance. Blanks are preferably checked prior to electroplating to ensure that their individual bands are continuous. The resistances of the bands of a blank are also measured prior to plating so that the electrical connection to the collectors of the blank may be so chosen as to ensure equal resistance bands in the finished glass panel. The connections are made to the collector adjacent the highest resistance bands. The continuity and resistance values are determined with an inductive sensor. Preferably the bands are applied by a silk screen and make an angle of between 14 and 76 degrees with the warp direction of the screen so that teeth are formed on the edges of the bands to facilitate subsequent electroplating.

Abstract: 1310021 Washing machines HOOVER Ltd 19 April 1971 [16 April 1970] 18260/70 Heading A4F [Also in Divisions D1 F1] A washing machine including a cavity for articles to be washed comprises at least two groups of nozzles 12, 13, 14, 15, each comprising at least one nozzle 18, the groups being disposed to produce sprays or jets at different positions in the cavity C1, C2, C3, C4, a fluidic circuit for supplying liquid to the groups of nozzles from a common source and at least one fluid logic element 20, 30, 40 included in the circuit and arranged to supply liquid sequentially to the groups of nozzles. As described liquid from pump 9 travels via tube 17 to fluid logic element 20 of the flip-flop bi-stable type. Initial output 22 of element 20 is to conduit A1 leading to nozzle group 12. Output also passes along feedback line 25, to control part 26 to switch output of fluid to outlet 23 leading to a second fluid logic element 30. A restrictor in feedback line 25 delays this switching for a predetermined time. Element 30 functions similarly to element 20; after a predetermined time the fluid output switches from outlet A2 to outlet 33 leading to a third fluid logic element 40. The fluid outlet of element 40 leads to conduit A3 and feedback line 45 which after a delay switches the output of element 40 to outlet 43 leading to conduit A4 and a loop 49. After a delay, loop 49 switches the output of element 20 from outlet 23 back to the original outlet 22, when the cycle starts again. Conduits A1, A2, A3, A4 and hence nozzle groups 12, 13, 14, 15 are thus fed sequentially, with the liquid. These fluid logic elements are said to be arranged in series. An alternative arrangement, Fig.3 (not shown), is described in which one element (50) feeds liquid in turn to one of two elements (60, 70) which are said to be in parallel, the respective outputs switching through feedback loops and restrictors as abridged with respect to Fig.2.
