An improved splicing method in which both the yarn ends to be spliced are once untwisted and then lapped and then the lapped portion of the yarn ends is subjected to the action of a compressed fluid. The length of the lapped portion arranged in a splicing hole having a jet nozzle can be changed appropriately according to kinds or count number of yarns to be processed.

The splicer head (5) of a pneumatic yarn splicer device (1) is provided on either side with pneumatic holding devices (15, 16) for holding the respective yarn ends (34', 35') of the yarns to be spliced together (34, 35), the inlet-mouths (33) of these holding devices having inserting aids for the yarn ends (34', 35') shaped as recesses (36, 37) of varying depth and of limited extent. With the help...

An automatic transmission system has a controllor for controlling the slip rate of a clutch in accordance with the amount of depression of an accelerator pedal instead of controlling the ON/OFF condition of the clutch by a control signal when it is discriminated that the gear change position of a transmission and the amount of depression of the accelerator pedal are in the predetermined states. In...

A lead storage battery comprising a battery casing has a first case member (such as a tray) and a second case member (such as a cover) in a superposed relation. The tray has a protruding part for mounting one external terminal, and the cover has a protruding part for mounting the other external terminal. The tray and cover have recessed regions for receiving the protruding parts for mounting the e...

This invention is obtained with improvements to splicer devices (10) making a splice between two yarns by the mechanical removal and recomposition of twists, such splicer devices (10) comprising means to untwist and retwist yarn which have a substantially circular form, such means possibly including operational means (70). Such splicer devices (10) include means able to pluck and/or tear exce...

A device (Fig. 2) for evenly spooling a trailing electric cable (32) onto a cable reel drum (38) mounted on a mine vehicle powered via that cable includes a rotatable cylindrical cam (102, Fig. 4) rotatably driven in a predetermined ratio to the speed of rotation of the drum. The cable passes to the drum through a reciprocable cable guide mounted on a pivotally oscillatable assembly (152, 138, 134...

An antimicrobial composition is prepared containing an aryl compound carrying an oleophilic substituent and a hydrophilic substituent, and an antimicrobial agent coordinated to the hydrophilic substituent. The oleophilic substituent is a straight alkyl radical from 6 to 24 carbon atoms and the hydrophilic substituent is a sulpho or hydroxyl group. The antimicrobial agent is an imidazole, a benzimi...

In a method for identifying one or more botanical component parts from plants, a sample of the component parts is irradiated with electromagnetic radiation within the visible and/or ultra-violet and/or X-ray range for excitation of the component parts to fluorescence which is analyzed for determining characteristic fluorescence from the component parts. For determining the relative contents of the...

PURPOSE:To attain an error quantity measuring system which can measure easily the quantity of errors existing in data, by discriminating whether data can be used or not in accordance with data type if the quantity of errors is small. CONSTITUTION:A transverse error correcting code ECC circuit 4 and a longitudinal ECC circuit 5 correct correctable data, and a number (p) of sections and a number (q)...

A guidance system for guiding a plurality of unmanned vehicles along a traffic layout includes a plurality of code devices which divide the traffic layout into a plurality of zones and identify each zone by a unique identifying code. Each vehicle includes control circuits having code sensors which sense the identifying code as the vehicle enters a zone and provide data to a present memory which st...

A frangible or breakaway valve for use in a flexible tube. The valve comprises two parts: a tubular portion with a closed end and an elongated, generally rigid handle breakably attached to the closed end. The elongated handle has projections which frictionally contact the interior surface of the flexible tube and prevent the elongated handle from moving back into a closed position once the elongat...

A control arrangement for internal combustion engines is presented, which outputs a resetting pulse when a microprocessor or a microcomputer does not operate correctly within a predetermined short test period. The cause of the disturbance is immaterial. The safety arrangement triggered for this is only cancelled again when the device operates correctly again over a plurality of test cycles. Such a...

A method for the failsafe representation of a mimic diagram on a data display device (M) is specified, in which the image data supplied to the data display device are continuously checked by the fact that a test code is formed by data reduction from the image data stream and this code is compared with a reference code previously stored and characteristic of the mimic diagram to be displayed. The r...

A shock absorbing material suited for use in automobile steering wheel comprises a core portion and a skin layer integrally formed on the core portion by foaming. The core portion and the skin layer are formed of isocyanurate ring-containing foam obtained by reacting polyhydroxy compounds having a hydroxyl value of 200 to 700, triethanolamine and polymethylene having a mean functional group number...

A method for altering the surface appearance or texture of a textile or other substrate comprises impinging the surface of the substrate (25) with a high velocity fluid jet (18) with water being a preferred fluid. The substrate is placed against a support (20), and a fluid stream having a peak dynamic pressure in excess of about 2068 kPa (300 p.s.i.g) is directed onto the fabric surface. Various m...

An automatic electronic remote control system is provided which is particularly adapted to control the operation of clutches for a hydraulic torque converter in a vehicle. Responsive to operating conditions, the system produces different control signals depending on whether the ratio of the frequencies of two series of pulses is above or below a predetermined value, the pulse frequencies being rel...

A first channel including filter 1 and photodetector 2 senses emission from a flame in the wavelength range below 6 mu particularly that characteristic of carbon dioxide and produces signals to be used to operate alarm means. A second channel including filter 9 and detector 10 senses spurious emission produced by other thermal radiators in the wavelength range of a long-wave spurious emission abov...
