Title: Device for ascertaining the gradation of gradated series of blackenings in photographic layers
IPC: G03C5/02
Filed: 1930-06-19
Abstract: 353,641. Photographic sensitometry. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. June 19, 1930, No. 18778. Convention date, Dec. 20, 1929. [Class 98 (i).] A comparison device for use in determining the density-gradation of photo-sensitive layers comprises a.transparent or translucent support provided with several series of areas of different known gradated density, all the series commencing with an area of the same density, and the difference between the densities of the first and last area of each series increasing from series to series. A strip of a light-sensitive layer, whose density gradation characteristics are to be determined, is exposed in steps to light which is increased in intensity in a predetermined ratio from step to step. After development, the density-gradation of the strip is determined by superimposing the layer and the comparison device in reverse relation, i.e. so that the lightest and darkest areas of the series on the developed layer coincide respectively with the darkest and lightest areas of the comparison series, and observing the combination by transmitted light. Superimposition with one of the comparison series will produce a combination exhibiting the same density in all the areas of the series, and this comparison series determines the density-gradation of the sensitive layer.

Filed: 1959-06-04
Abstract: 890,186. Tobacco smoke filters; cigarette holders. MACFARLAND, AVEYARD & CO. June 4, 1959, No. 19166/59. Class 130. Tar &c. is removed from tobacco smoke by passing the smoke through a single orifice of area between 0.0005 and 0.001 square inch so that it impinges at high speed on a barrier 18 on which the tar is deposited. In a cigarette holder, Fig. 3, comprising a mouthpiece 12 and removable holder sleeve 10, the smoke passes through an orifice 17 into a slot 18 the rear wall of which is at a distance of 0.1 inch from the orifice and forms the impingement wall. The smoke flows through space 19a and passage 22 into the mouthpiece passage 13. The tar deposited on wall 18 collects on the surface of the part 14, a ridge 20 preventing it reaching the passage 22. The mouthpiece 12 may be made of nylon, the lips 16 of the inner end being resilient to wipe the inner surface of sleeve 10 when it is removed for cleaning of the inner portion 14. In a modification. Fig. 9, the barrier member is formed by an absorbent filter 36 held in position by a pin 40 which may be used for cleaning the orifice 33. In Fig. 8 the orifice member 27 is situated in the cigarette mouthpiece between a pair of filters 25, 26, the latter forming the impingement member.

Title: Improvements in and relating to brush gear for carrying current in dynamo-electric machines
Inventor: BERGER BRUNO
IPC: H02K9/28
Filed: 1960-05-31
Abstract: 967,623. Cooling brush-gear. C. A. PARSONS & CO. Ltd. May 24, 1961 [May 31, 1960], No. 19189/60. Heading H2A. The brush-gear in a dynamo-electric machine, for example the slip-ring brush-gear in a turbogenerator, is liquid cooled. In a first embodiment, Fig. 1, the housings 2 for the brushes are surrounded by a channel 3 through which water is circulated by a pump, inlet and outlet connections being provided at 4 and 5, respectively. The inner surfaces in contact with the liquid may be provided with fins to improve heat transfer. Fig. 4 shows the arrangement of the brush boxes of Fig. 1 in a dynamo-electric machine. Each brush box is attached to a respective bracket 10, the brackets in turn being supported on a plate 12. The boxes are connected in parallel with supply and discharge pipes 8, 9 for the cooling liquid. Cooling may alternatively be effected by the evaporation and subsequent condensation of the cooling liquid in a closed system. In Fig. 5 the brush box 16 and bracket 17 therefor are hollow with the cavities therein in direct communication. The cavities are filled with vaporizable liquid to a level above the brushes 19 as may be seen through the inspection window 21. The heated liquid vaporizes and rises into the cavity within the bracket 17 where it is cooled by a gas such as nitrogen, hydrogen or argon circulating over the outer surface provided with fins 22, a cooling gas other than air being used to reduce oxidation of the brushes. This, however, necessi- _ tates sealing the brush gear and to avoid the need for frequent access thereto, brushes at least 6 inches long and constant tension springs 23 are used. The voltages developed across resistors 24 in series with the leads 25 are monitored to check that no brush is carrying an excessive current. Instead of using a plurality of sealed brush boxes a common condenser may be used for a plurality of boxes, the condensate being returned to the boxes either under gravity or by a pump. In a further alternative solid brush boxes may be used, the brushes being cooled by liquid flowing through flattened tubes brazed to the boxes. As the cooled brush gear permits a heavier current flow, conductors of increased current-carrying capacity leading to the brushes are needed. This may be achieved by interposing a graphite or copper-graphite sleeve between each brush and the corresponding wall of the brush box, current then passing directly from the brush through the sleeve to the brush box, Fig. 12 (not shown). Alternatively, in machines in which the leads to the brushes carry direct current, thermo-electric cooling of the leads may be employed, Fig. 11 (not shown).

Abstract: 1487546 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 11 May 1976 [30 June 1975] 19335/76 Heading H1K A method of forming a dielectric isolation region typically in an integrated circuit comprising a bipolar transistor, comprises the steps of depositing a layer of aluminium in an etched recess (28), Fig. 2C (not shown), formed using an insulating mask 26, 27, anodizing aluminium layer portion (30) in the recess to form the isolation region 32, and then removing the unanodized aluminium layer portion 31 on the insulating mask. An optimal thin layer 29, typically 200 Angstroms thick, of silicon dioxide formed in the recess prior to the deposition of aluminium, permits the aluminium layer portion (30) to be maintained at a potential by applying a positive voltage to the substrate during the anodization of the portion 30. The unanodized aluminium layer portion 31 is removed by a "lift-off" process involving preferential chemical etching of pyrolitically deposited silicon dioxide layer 27. Unanodized aluminium layer portion (18), Fig. 1E (not shown), on a single layer silicon dioxide mask (13) is removed using a solution to which recessed aluminium oxide is resistant. The unanodized layer portion may also be removed by chemically etching it while masking the recessed aluminium oxide with a photoresist mask (39), Fig. 3E (not shown). A highly doped P region around the bottom of the recessed aluminium oxide in the P-type substrate may be provided to prevent short circuiting of the semi-conductor regions.
