In an automatic winder, presence or absence of a yarn on a package side and a yarn on a yarn supply bobbin side is detected during one cycle of yarn joining operation of a winding unit, and the winding unit after completion of a yarn joining operation is selectively instructed that an indication that yarn joining is impossible is to be made or that yarn joining is to be waited for.

A vehicle, for instance a fork lift, in which a hydraulic pump (13) for driving the fork (15) is driven by an engine (1) serving also for moving the vehicle, employing an automatic transmission (3, 2) for movement of the vehicle, is provided with inching control means (9, 6, 7, 8) which control a clutch (2) for separating the movement system (4, 5) and the cargo handling (fork) system (13, 14, 15)...

The flotation plant has a collecting tank (12) provided with a dispersion feed pipe (10), a flotation tank (14), a device (16) for introducing air into the dispersion to be purified, a device (18) for the metered addition of cleaving agents and a flotate dewatering device (20), with a mixing section (22), which is connected through a first feed pipe (24) to the collecting tank (10), is connected t...

The running thread (3) is monitored. When a fault occurs, the cross-wound bobbin (14) is stopped automatically in the shortest possible time as a result of the actuation of quick-action braking devices (50, 51). An interruption of the thread (3) is thus avoided. Only after the standstill is the thread (3) severed as a result of the actuation of a thread-severing device (9) and the fault eliminated...

An exchangeable thread guide for the traverse motion on a textile reel winding machine, consists of a casting with a long smooth shoulder on one side, and held on a base plate. A short shoulder on the opposite side is cut away near the base plate to allow entrance for the thread, and a central tube like structure retains the thread in position during winding. The casting (37) is made of ceramic an...

A method of winding a belt-shaped member (3) is used in winding a tire member around a forming drum (11). A position of a leading end (3a) of a tire member is detected to obtain a shifted distance of the leading end relative to the forming drum. The leading end is then transferred to the forming drum, while the leading end is being moved in a width direction to make zero the shifted distance. The ...

The perforations in a film-faced wound dressing have been discovered to have edges which, though clearly defined, lack the ability to cut the neoepithelium of a healing wound, with the result that the film affords an unexpectedly high degree of comfort during movement of the patient-and most particularly, when the dressing is changed. This occurs in a thin, soft, self-supporting elastomeric film, ...

PURPOSE: To enhance catalyst activity and selectivity by treating a zeolite with an aq. medium contg. cations of K, Na, Sr, Ba or the like in such a manner that the zeolite maintains pH in a range of 9.4 to 10.0. CONSTITUTION: The aq. soln. which contains >=1 kind of cations of K, Na, Sr, Ba, Ca. Li, Mg, Rb, Ce and has the pH within a range of 9.4 to 10.0 is prepd. The zeolite is washed with the a...

1. Installation for the point-to-point transmission of data between the track and a vehicle travelling on this, consisting of ground equipment (5) fastened to the track and comprising a transmitter which transmits the coded information from a track signal (11) by means of a transmission marker (9), and of on-board equipment (1) accommodated in the vehicle (3) and comprising a receiver (151, 152, 1...

The invention relates to a method and an electrical circuit for determining and/or limiting a high-frequency energy supplied with a catheter by utilising the change in resistance of the electrical resistance of the treated tissue or vessel part during application of HF energy (Fig. 1).

The positional error of an integrated navigation system increases with increasing time and increasing distance travelled. In the case of free navigation in the industrial field, the travel course stored in the vehicle must always be maintained within a specific tolerance, on grounds of safety. For this purpose the invention provides that small magnets let into the track non-uniformly be used for t...

Stable, 1-component polyurethane foam mixt. (I) used in an aerosol can or other pressure container, comprises a prepolymer (II) obtd. from a polyol component (III) and a polyisocyanate component (IV), and a catalyst, fire retardant, plasticiser and propellant gas/blowing agent (V); the novelty is that (III) has mol. wt. 2000-65000, (II) has dynamic viscosity 200-4000 mPa.s and 2-40 wt.% N2O is use...

An apparatus and technique for applying markings or decorations to the sidewall of a cured tire. A thin polyester carrier sheet has a thermoplastic transfer stock thereon. A heated die is provided having thereon the geometric configuration of the desired marking or decoration. The heated die is urged against the transfer laminate to impinge the transfer stock against the sidewall of the cured tire...

The device uses a magnetic field produced by a system placed along the direction of the track to be followed. The device comprises two magnetic sensors (2, 3) mounted on the vehicle which receive and detect the field. The system producing the field is a waveguide (1) which, for the determination of any sideways deflection with respect to the direction of the track, is connected to a radio transmit...
