Title: Method and apparatus for measuring the amount of moisture of coating having a transmission spectrum similar to water associated with a web of moving material
IPC: G01N21/31
Filed: 1976-06-03
Abstract: 1511418 Spectrometric analysis MEASUREX CORP 3 June 1976 [12 June 1975] 23032/76 Heading G1A Apparatus Fig. 1 for measuring the amount of moisture, or of a coating of a material having similar spectral characteristics to water, associated with a moving web by measuring its absorbancies at two wavelengths which are respectively strongly affected and relatively unaffected by the moisture or coating, further includes a filter 33 having spectral characteristics similar to those of the moisture or coating and arranged to be selectably interposed in the radiation path. In scanning apparatus for measuring the moisture in a moving paper web 14, IR radiation from a tungsten lamp 21 is collimated 23 and chopped 27. Transmitted radiation is collimated 31, split 34 and measured by PbS cells 38, 42 at wavelengths determined by filters 37, 41 having pass bands around 1À7Á and 1À94Á respectively Fig. 2B. Both these wavelengths are transmitted by paper, Fig. 2A, but 1À94Á is strongly absorbed by moisture. Errors due to deposits of moist dirt on the apparatus are separated from those due to variations in the apparatus itself, by calibration and measurement methods which, include the provision of a selectable filter 33 Fig. 1 having a short-wave-pass or bandpass curve, Fig. 2C with a half-height at 1À895Á corresponding to a spectral characteristic of moisture. The apparatus is first calibrated by a series of measurements wherein an empty aperture 30 Fig. 1, the filter 33, and a number of polytheneenclosed paper samples having known moisture contents, are interposed in turn in the radiation path, the measurements being repeated while increasing numbers of layers of moist tissue, simulating moist dirt, are taped across an aperture 26 Fig. 1 in the radiation path. From this information a curve relating the response of the apparatus to actual moisture - bearing paper, to its response to the filter 33, is compiled for use in operation. The apparatus may be applied to measure the weight of a coating, e.g. polythene, having spectral characteristics similar to those of water.

Title: Improvements in and relating to epicyclic variable speed transmission mechanism
IPC: F16H61/02
Filed: 1933-08-18
Abstract: 418,777. Controlling variable-speed gearing and friction clutches. REO MOTOR CAR CO., 1331, South Washington Avenue, Lansing, Michigan, U.S.A. Aug. 18, 1933, No. 23117. Convention date, Jan. 30. [Class 80 (ii).] In two-speed epicyclic gearing in which the higher speed is effected by engaging a friction clutch H by means of centrifugal weighted levers J, the weighted levers J are carried on the driven gear member such as D and their weighted ends co-operate with yieldable catches O. In the low-speed position of Fig. 1, the clutch H is open and the levers J are held in their collapsed position by a spring ball O within each weight engaging a recess N<2> in a pin N which passes radially and loosely through the weight. A sun pinion B fast on a driving-shaft A then drives the internally-toothed driven gear D at reduced speed through an internally and externally toothed planet ring E supported eccentrically on a carrier F which is prevented in this speed configuration from turning backwards by a one-way roller brake G. When the speed of the driven member D increases beyond a definite amount, the balls O slip out of the recesses N<2> and the weighted levers J fly out to the position shown in Fig. 3. Thus a clean-cut change into high speed or solid drive is effected, T-ends K<1> on the levers J thrusting the plates of the clutch H into driving engagement so that the carrier F is forced to turn forwardly along with an enveloping clutch drum I which is rigid with the driven gear member D.

Title: Improvements in or relating to photographic cameras
IPC: G03B7/12
Filed: 1960-07-04
Abstract: 897,769. Photo-electric exposure control. GAUTHIER G.m.b.H.. ALFRED. July 4, 1960 [July 14, 1959], No. 23229/60. Class 40(3). In an automatic exposure control device for a photographic camera, a scanning member arrested by an exposure meter pointer positions a lever or slide which in turn arrests an exposure setting member. Actuation of the shutter release 3 permits the scanner 5 to engage the meter pointer 8 which is first clamped by a spring 14. Scanner 5 pushes the lever 9 into an angular position dependent upon the position of pointer 18. Further movement of release 3 rocks a pawl 31 to free the cam disc 26. Disc 26 is geared to a pinion 23 driven by a spring 21 which pinion rotates to bring a member 4 which is coupled to an exposure factor regulator into contact with lever 9. Cam 26 rocks a lever 35 to release a disc 36 which rotates and oscillates the shutter operating ring 43 by means of a pawl 46. The shutter opening is retarded by a lug 43a encountering an escapement 52, 63, 57, until the correct exposure valve is set. The release 3 may be freed at once, lever 9 remaining engaged with member 4 until springs 21, 17 are retensioned by the film feed lever 24. Members 4, 5, 20 shown as slides may be rings or discs.

Patent GB-1014335-A (GB)
Title: Gas diffusion electrodes
IPC: G01N27/49
Filed: 1962-06-18
Abstract: A porous gas diffusion electrode comprising two or more layers, each of which is formed of sintered metal powder, is produced by assembling together at least two coherent and pore-free layers which have been pre-formed by casting a suspension of a sinterable pulverulent material in a solution of a binding agent and evaporating the solvent, and subjecting the assembled layers to sintering whereby the metal particles in each layer are sintered together and the several layers are sintered into a unit, the binding agent being such as to form products which escape from the assembled layers on sintering to leave the layers in a porous state.  The pre-formed layers may be produced by applying a suspension of powdered metal in a binder to a carrier, which may be of paper and decomposed during sintering or of a non-bonding material unaffected by sintering, e.g. iron or brass.  The powdered metals used may be one or more of carbonyl Ni or Fe, electrolytic Cu, Ag, binary Raney allows of Al with Ni, Cu, Ag, Fe, Pd, or Mo, or similar alloys in which the removable metal is Zn or Mg, while the binders may be watersoluble animal glue, methyl cellulose, or "Zapon" varnish comprising nitrocellulose, hard gum and alkyd resin.  In specific examples the materials used are carbonyl Ni, or sizes <5m  in an acetone solution of Zapon varnish (material A) and a 1.6 mixture by weight of carbonyl Ni of size <5n  and an alloy of equal parts by weight of Al and Ni of size 35-50m  (material B).  Three-layer electrodes may be made by preparing preforms of material A and placing between them a preform of material B in "Zapon" varnish binder followed by pressing and then sintering in hydrogen at 650  DEG C. whereafter the aluminium in the middle layer is removed with caustic soda solution.  Alternatively the material B without binder may be placed between preforms produced by spraying paper or oxidized iron with material A.  With iron carriers a stack of components for three electrode may be treated simultaneously.  In another arrangement for a five-layer electrode, brass carrier discs are sprayed with material A, material B is sieved on to the coating and then sprayed with "Zapon" varnish and over a disc so coated, coatings uppermost, is placed a 2.1 mixture by weight of carbonyl Ni of size <5m  and KCl of size 200-400m , which thereafter is covered by the coated face of another brass disc. After hot pressing and sintering, the potassium chloride is dissolved out.
