Abstract: 1,214,262. Direct connections between conductors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Feb., 1969 [16 Feb., 1968], No. 7911/69. Heading H2E. [Also in Division H1] Electrical contact strips 5, 7 deposited on flexible insulating sheets 1, 3, e.g. of synthetic resin, are pressed together by an external force, causing them to make direct electrical contact where they cross each other at a plurality of places. As shown, the arrangement forms part of a magnetic store comprising the contact strips, ferrite bar 31, ring-hole 29, aperture 27 and a sensing element (not shown). Contact strips 15, 17 carried by sheets 11, 13 respectively are electrically connected by strip 19 (Fig. 2). Strip 21 electrically contacts the strip in opposition, and strip 23 has no current conductive function, but serves to make up the thickness of the stack. Terminal 9 provides access for a current impulse through strip 5 to the magnetic store. The strip contacts 5, 7 as shown are of zig-zag form; alternatively one of them may be curvilinear and the other linear (Fig. 4, not shown).

Filed: 1923-03-20
Abstract: 214,801. Erste Br³nner Maschinen- Fabriks-Ges., and Losel, F. March 20, 1923. Drawings to Specification. Axial-flow type; regulating; motor power plant; working-fluid supply.-To avoid losses in a high-pressure multi-stage steam turbine consequent upon high steam velocity, which is stated to cause a rise in pressure when the steam is passing through the rotor, the turbine is so constructed that the steam velocity throughout the stages does not exceed 140 metres per second. For this purpose, the cross sectional areas of successive sets of nozzles have a ratio of not more than 1.25. A turbine so constructed may be used as a back-pressure turbine or with a lowpressure turbine on a separate shaft geared to the high-pressure turbine shaft, the shafts being either parallel or at right angles to one another. The high-pressure turbine is controlled so as to keep the back-pressure uniform or/and the nozzle pressure at its maximum irrespective of speed variations.

The treatment (a) may be by solvent extraction, e.g. with cyclohexane or heptane, centrifuging, or filtration. The treatment (b) may be by subjecting the polymer to shear as a solution or dispersion in an organic solvent or dispersing medium, or a carrier oil, or a plasticizer, or as a molten polymer.

Title: Improvements in or relating to Particle Detectors
IPC: G01N21/53
Filed: 1967-02-20
Abstract: 1,160,149. Photo-electric smoke detector. PYROTECTOR Inc. Feb.20, 1967 [March 10, 1966], No.8028/67. Heading G1A. A particle detector comprises a light source for illuminating particles to be detected, photoresponsive means positioned to view the illuminated particles, an alarm actuator normally biased to the actuating condition but rendered non-actuating by energization of the source, and means responsive to illumination of the photo-responsive means by particle presence to overcome this non-actuation whereby the alarm is actuated. Contacts X1 in the alarm circuit, Fig. 3, are held open by relay R1 when it is energized by half-cycles passing through a diode D1 and a photo-cell PC2, which is made conductive by light from lamp 14. Particles of smoke are detected by cell 16 and ignite a neon tube 50 to make a further photo-cell PC3 conductive and thus permit the passage of both half-cycles from source E to the relay R1 which, being shunted by a capacitor F, releases to actuate an alarm, and to effect a control such as closing firedoors. The photo-cell PC2 may be replaced by the contacts of a relay. The detector element (16, Fig.1, not shown) is housed in a tube (38) fitted radially in the wall (18) of a housing (12) and at right angles to a beam from a source (14) which is mounted on a panel externally of the housing to permit a visual check. End caps (26, 28) for the housing are fitted over spacing lugs (30) to allow for the passage of smoke. A light trap tube (34) is mounted in the housing opposite the light source, and screens (42, 44) prevent the direct ingress of light i.e. other than that from the illumination of particles. A lens (36) focuses light on to the bottom of the light trap, and a lens (40) focused on the opposite housing wall is provided in the detector tube.

Title: Processing of photographic silver halide materials
IPC: G03C5/30
Filed: 1976-02-04
Abstract: 1530453 Developing photographic materials AGFA-GEVAERT 4 Feb 1976 [27 Feb 1975] 8307/75 Heading G2C Latent halftone images in a photographic silver halide lith materials are developed in an automatic processing machine with a lith-developer containing: a p-dihydroxy-benzene developing compound, free sulphite ions and an alkali metal bromide, the developer containing not more than 0À05g per litre of one or more auxiliary developing compounds that show superadditive developing effect with the p-dihydroxy-benzene developing compound. Two replenisher solutions RD and RA are added to the developer, in which (1) the pH of R D  is higher than that of RA (2) the halide ion and free sulphite ion concentrations of RD are lower than those of R A ; (3) the p-dihydroxy-benzene compound concentration of RD is different from that of R A  and the ratio by weight of p-dihydroxy-benzene compound to free sulphite ions in RD is different from the corresponding ratio in R A . The addition is controlled through the results of checks on the performance of the developer with respect to a lith silver halide emulsion material that has been exposed through one or more sensitometric wedges and subjected to development in the actual developer to produce a halftone wedge print whereon the distance between areas of different dot values is read and compared with a reference distance, the deviation serving for guidance in determining partial replenishment by replenisher R A , and the location of a sensitivity point on the halftone wedge print or on a continuous tone wedge print with respect to a reference sensitivity point serving for guidance in determining partial replenishment by replenisher RD. When a shift to lower sensitivity values is observed the rate of replacement by RD or a mixture of R D  and R A  is increased and/or an extra amount of R D  or R D  and R A  mixture is added. Depending on whether a decrease or increase of the distance read is detected by checks an amount of R A  is added and/or the rate of addition of R A  is increased, or the rate of addition of R A  or the amount of R A  in the R D  + R A  mixture is diminished. In an example test strips exposed through a continuous wedge with a parallel millimeter scale and a magenta contact screen are developed every 2 hours in a processor in which lith film is being developed. The sensitivity reference point is taken at a density 0.04 above fog level and the distance between areas of 10% dot area and 95% dot area is measured. Replenishers are added when on three successive strips a deviation greater than 2mm in either value is observed.
