In a battery containing an electrolyte cured by the addition of a gel former, the complete filling of the battery by the electrolyte and the stability thereof in all operating states is ensured if the gel former consists of at least two components which by virtue of combining with one another have effected curing. In a process for manufacturing a battery of this type for an aqueous electrolyte, at...

In repairing a broken yarn, at a two-for-one twisting machine, if the repair sequence fails to splice the broken yarn, then the splicing action is repeated. The broken ends are untwisted to open them out and then twisted together in a splicing action to join the upper and lower ends. The lower yarn section is clamped after insertion into the splicer. The splicer can test the splice and, if the j...

A procedure for separating emulsified components from water by partial floatation makes use of a mixing device, an aeration device and a floatation vessel. After the separation by floatation the water passes through at least two clean-water tanks. The pH in the second clean-water tank is adjusted. A combined pH-controlled water flow from the two clean-water tanks is produced and passes to the mixi...

The coil (2) surrounds an armature (3) of magnetic material and is wound on a magnetic guide (4) having a substantially cylindrical section (5) around the seating (6) within which the armature slides w.r.t. a fixed pref. magnetic pin (11). This acts as a distributor of fluid through two longitudinal channels (14,16) and two transverse channels (15,17) between a pressurised source and a load. The a...

Equipment is provided on a warping creel to indicate the pattern requirement, so that a suitable reel of yarn is placed in the correct position, when a variety of yarn is being assembled. The indication arrangement may be in respect of one or more reel positions, and the indication equipment may be moved relative to the creel. USE - To enable personnel to place correct reels on the creel-pegs quic...

In comparison with conventional terminals of lead-acid accumulators, which are cast in two-piece moulds and must be reworked in order to remedy the separating seam which prevents sealing, a new terminal (1) is produced by extrusion moulding, having an insert (2) consisting of a metal which is harder than lead. In this case, lead is initially forced out of the core of a lead profile by means of a d...

The invention provides a method and apparatus for continuous sheet delivery. According to the invention, a continuous stream of sheets is separated into a main pile, supported by a removable pallet, and an auxiliary pile, in which sheets are stored while the pallet and the main pile are removed and a new pallet is introduced. An embodiment of the invention includes a sheet supply, a pallet for acc...

In the case of an electromagnet which is provided with an armature and whose rod is used for carrying out control processes, the production of the armature and of the housing is intended to be simplified, and thus made cheaper, and scrap (wastage) is intended to be largely avoided. For this purpose, it is proposed that the rod pass through the armature over its entire length and consist of plastic...

The X-ray appts includes an X-ray generator (4) and X-ray image amplifier (5) which are connected to a C-shaped frame (3). The frame (3) is movably suspended in a holder (9) along its circumference. The X-ray radiator (10) is fitted into a housing (12) filled with a dielectric (13). The housing (12) contains a heat exchanger (30) which is connected to a cooling unit (2) outside the X-ray generator...

The mobile X-ray machine has a C-shaped mounting arm (3) with an X-ray source (4) and X-ray image intensifier (5) mounted on a trolley (1). The C-aim (3) is mounted on a carrier (9) which allows rotation of the C-arm. The carrier (9) is adjustable in height by extending the mounting column (7, 8). The control panel for the machine (2) is adjustable in height, and positioned for ease of use in oper...

A caddy (1) for transporting a textile bobbin (12) has a base disc (2) and a spigot (5) with a slightly smaller dia. than the bobbin tube (14). The spigot (5) has a friction surface which resists displacement of the tube (14) in its mounting on the spigot. The spigot can be conical and can have an elastic surface layer (8) e.g. rubber. The spigot (5) is covered with a replaceable rubber sleeve (8)...

The invention relates to a thread dispensing device, especially for a retraction thread 10 which can be unwound in predetermined lengths from a storage roll 14 rotatably mounted in a housing 12, can be severed on emergence from the housing 12 by means of a cutting device 18 and which is guided in the housing 12 for emergence with transportation by a drive unit 20 which comprises at least one drive...

A blood component separating device comprises a centrifuge bowl adapted for rotation about its axis in a centrifuge. The bowl defines an outer arcuate wall plus an inner circumferential wall, spaced from the outer wall, to define a arcuate slot adapted for receiving blood components. Access tubing is adapted for communication with the slot. Preferably, an elongated, flexible, collapsible inner lin...

A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient preheating of the sheet prior to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, taking them togeth...
