PURPOSE:To prevent any separation of an active material, equalize the conditions of plates and simplify the process of manufacturing the plate by specifying the total thickness of the plate as the thickness of a grid frame, which is provided around a grid and has a function of partitioning and controlling the packed amount of the active material in order to satisfy such a specification. CONSTITUTI...

PURPOSE:To increase the energy density, enhance the high-rate electric-discharge characteristic and increase the short-circuit current of an enclosed lead storage battery by installing positive and negative plates in a battery jar with a separators interposed, and carrying out formation at an atmospheric pressure below 15 deg.C after a specified amount of electrolyte is poured in the battery jar. ...

An improved polymer sheet. The improvement is at least one surface polymer film layer and at least one fabric veil. A veil is laminated between each surface polymer film layer and the polymer sheet. There is a method of heating a polymer sheet containing the improvement of the present invention.

A stack comprising a plurality of vulcanisation mould plates assigned to the press is located in the open press. The...

The invention relates to a device for measuring the colour density of moving sheet- or web-shaped print materials (1) having colour control strips (3) printed at intervals transverse to the direction of motion, whose measuring fields (4) are illuminated by means of light guides (11) assigned thereto, while the radiation reflected from the measuring fields (4) is received by means of further light ...

Unsaturated glycol diesters are prepared in an extremely high degree of conversion and selectivity by reacting a conjugated diene, a carboxylic acid and oxygen in the presence of a solid, active, long-lived catalyst composed of a mixture of palladium and at least one component of antimony, bismuth, selenium or tellurium supported on activated carbon, which catalyst is prepared by subjecting the mi...

Broken ends of a spun yarn are introduced into a hole of an air nozzle device from upper end and lower end of the hole respectively and the yarns are doubled. The doubled yarns are slightly slacked and subjected to air jetting by the air nozzle device to produce a spliced joint. The distribution of twists inherent of spun yarns is changed in the region of the spliced joint by twists imparted to th...

1,195,485. Unsaturated esters. BP CHEMICALS (U.K.) Ltd. 24 Feb., 1969 [9 March, 1968], No. 11650/68. Heading C2C. Unsaturated aliphatic carboxylic acid esters, e.g. 2-hydroxyalkyl acrylates and methacrylates are prepared by reacting the corresponding acid at elevated temperature in the liquid phase, with an epoxy compound in the presence of a chromium salt of a carboxylic acid. The salt may be pre...

A practice for applying indicia to the surface of a precious stone wherein a source of laser energy is directed at the stone surface and controlled to inscribe the surface with the desired indicia.

Lumps of a mineral or like material comprising two or more solid phases at least one of which is electrically semi-conductive and of different conductivity and permittivity from the other or others are subjected while immersed in water or other high dielectric medium, to the action of an electrical discharge of high enough potential to ionize the mineral. The discharge so generated crushes the lum...

This ski binding device of the toe or heel hold-down type comprises a member for clamping or holding the toe end or the heel of the ski boot against any undesired upward movement, said member being movable vertically upwards on its support and adapted to be shifted in this direction by means of a vertically movable adjustment member on which said clamping or holding member bears in the downward di...

A safety ski binding having a reinforcing member on a ski boot, which ski boot has a shaft portion which is pivotal about a transverse axis. The reinforcing member has a shoulder thereon which is engageable with a removable support to limit the backward pivoting movement of the shaft portion but permit a desired amount of frontward movement. A lever is provided which is movable into and out of sup...

A carry look-ahead parallel digital adder having a relatively wide overall data flow width and a pair of automatically adjustable boundary mechanisms for subdividing the adder into plural independent operating zones of variable width and variable location. Anywhere from one to three independent zones may be obtained. Independent external carry-in and carry-out lines are provided for each zone and ...

The ski binding comprises a pivotable sole support (13) which is coupled to the heel support (39-44) by means of a connection, for example a toggle lever (29, 33), which can be shortened. The heel support is assigned an extension (46) directed to the rear in a fixed reference position. The extension (46) is inserted under a holding-down means (48). The connection (29, 33), which can be shortened a...

A process for utilising refuse comprises first separating the refuse into at least one paper fraction (which is further processed for producing fibrous material) and a residual fraction, the slops (e.g. plastics films, textiles) accumulating during the production of fibrous material from the paper fraction being subjected to pyrolysis together with the residual fraction and the heat obtained is us...
