PURPOSE:To increase the charge-discharge cycle life of a maintenance-free battery by forming a vacant space between an expanded grid and paste paper, then filling paste in the grid. CONSTITUTION:Paste paper is placed on a paste filling belt and piano wires having a diameter of 0.5mm are arranged at 15mm intervals, then an expanded grid is placed thereon. The grid is continuously filled with paste ...

A system for controlling an electro-magnetic clutch for automobiles has a stepwise increase of the clutch torque for reducing the engaging shock. The system comprises a gate circuit for producing a signal by signal by shift lever clutch operation, a monostable multivibrator for producing a clutch engaging period signal by the output signal of the gate circuit for a predetermined clutch engaging pe...

A safety toe unit for a ski binding has two sole retaining jaws (11, 12) which can pivot laterally outwards in opposite directions. A respective projection (13, 14) of a pressure member (19) acts on each of the sole retaining jaws at the front between the pivot axes (15, 16) and shoe retaining rollers (17, 18). The pressure member (19) is arranged for displacement in the longitudinal direction of ...

Plastic film, produced substantially from recycled polyethylene, contains at least 10 per cent by weight of linear low- density polyethylene having a density beneath 0.915, thereby improving the welding properties and mechanical properties of the film. The plastic film is particularly suited for the manufacture of sacks, primarily sacks for the collection of rubbish or garbage by local authorities...

In order to improve the accuracy of borehole survey systems utilizing probes with inertial components including inclinometers, two ring laser gyro units are included to provide rotation information 56, 58 to the system. When the probe is moving in a borehole, inclinometer information 50, 52, 54 is used 78 to produce a synthetic rotation signal 80 to take the place of a third gyro and the earth's r...

A device for transmitting signals from a transmitter at the bottom of a drill well to the earth's surface including a drill collar which extends in an axial direction, a transmitter disposed in the drill collar, a cylindrical metal sleeve from forming part of an antenna for electromagnetic wave transmission, the cylindrical metal sleeve being disposed around the drill collar and connected electric...

New ethylenic ketones of the general formula wherein R represents a 2,6,6- trimethylcyclohex-1-enyl radical or a 2,6-dimethylhepta-1,5-dienyl radical and R1 represents a straight- or branched-chain alkyl group containing from 1 to 4 carbon atoms are useful in the synthesis of vitamin A and lycopene.

The invention is concerned with a fine filler for dental purposes, comprising finely divided particles of hydroxy-apatite or tetracalcium phosphate and a calcification promoting protein selected from the group consisting of phosvitan, casein and histidine-rich protein. The fine filler of the invention is particularly useful for protecting or restoring pits, fissures or minute decalcified surface l...

The invention relates to the production of stress, temperature and shape sensors integrated into various industrial products such as, for example, those intended for the biomedical sector. The sensor includes a layer of cholesteric polymer whose colour, related to the properties of selective reflection of light by the material, is initially uniform and varies under the effect of a change in stress...

According to the invention, it is attempted to maximise the function of intercorrelating a reference signal, corresponding to the scanning of a basic pattern through a slot (18, 19), and a recognition signal, corresponding to a scanning of an image containing the said pattern, under conditions identical to the first scanning.

The method and the device provides for the automatic processing of digitalized signals in order to remove speckle from the said signals by comparing the digitalized signal with a noise model obtained after learning its statistical properties, extract, from the signals, echos not characteristic of the contour of the organ to be displayed, extract the characteristic parameters of the contour from th...
