CONSTITUTION:A continuously expanded belt-shape substrate 1 is passed between a filling machine hopper ...

PURPOSE:To manufacture a light weight, performance battery using a light weight and low resistance grid by molding an active mass in a shape of electrode plate and reducing a part of the active mass to metal lead to convert it to a grid. CONSTITUTION:A substrate 16 filled with an active mass 18 is placed in an atmosphere of H2 gas, infrared rays 20 from an infrared lamp 19 are condensed with a con...

Hygiene material, for example lavatory paper, comprises a layer which in use is substantially water- impermeable and after use and when placed in water at least partly dissolves to give a reduced wet strength. A further layer of liquid-absorbent material is laminated to the layer. The layer 10 may be liquid- absorbent paper coated or impregnated with material having a transient water-insolubility ...

A L-shaped bunch winding-regulating guide is fixed to a cradle arm so that while a bobbin holder is located at the position for bunch winding on a bobbin, a yarn gripped by the bobbin and bobbin holder is inhibited from shifting to the traverse region on rotation of the bobbin.

An apparatus for producing a plastic container having occludable closure strips comprises a source for the closure strips, a rotatable casting cylinder having a pair of spaced apart circumferential grooves defined therein, a mechanism for advancing the closure strips to the casting cylinder, an extruder for casting a plastic film onto the casting cylinder so that it becomes connected to base porti...

Benzamidoalkyl mercaptans having the formula: wherein R represents a hydrogen atom or a halogen atom or a lower-alkyl, lower-alkoxy, amino, carboxy or trifluoromethyl group, and alk represents a straight or branched divalent alkylene radical of from 2 to 4 carbon atoms and n is 1 to 3 are used as mucolytic agents in combating lung mucus.

A rotary die cutter for die-cutting blanks one after another has a blank feed unit, a pair of cylinders for die-cutting the blanks, and an endless member running synchronized with the cylinders. The blanks are gripped by grippers mounted at equal spacings on the endless member. The cylinders are adapted to allow the grippers to pass between the cylinders while gripping the blanks.

Apparatus for withdrawing a thread from a spinning station comprises at least two withdrawing rollers, which are preceded by a reciprocating thread guide and are succeeded by a winding device, which comprises a traversing device. In order to ensure that a reciprocating motion will be imparted to the thread guide, the latter is provided on one arm of a double-armed lever, which is freely rotatably ...

In the cell-separating walls (3) of a multi-cell accumulator block (1), cavities (5) are formed during the injection moulding by injection needles supplied with air, which cavities (5) can be inflated subsequently by the injection of a plastic (6) which can form foam, e.g. polyurethane. The wall-bubbles (7) formed in this way produce a compression pressure which also ensures fixed, permanent posit...

Method and device for freeing a filter medium, which has a certain inherent stiffness and is comprised in a filter, of dust separated from air, which filter (2) at one end is connected to a supporting plane (1) and in its longitudinal direction is oriented substantially perpendicularly to the supporting plane (1). The cleaning of the filter cloth is effected in that a strocke is imparted to the su...

Films comprising alpha-olefin polymers, such as normally solid polypropylene consisting essentially of recurring propylene units and having a substantial crystalline polypropylene content, and in particular isotactic polypropylene, are rendered easily thermoweldable and/or impervious to gases and vapors, and also given improved resistance to sticking against the welding bars of automatic and semi-...

There are disclosed polyolefinic films carrying two coatings, the first coating consisting of amino compounds and the second of a mixture of vinyl or vinylidene polymers or copolymers, epoxy resins and microcrystalline waxes, and which films, by virtue of the coatings, are readily thermoweldable, impervious to gases and vapors, and have improved resistance to sticking to the bars of conventional a...

A replaceable insulating sleeve (20) is disposed around the lower end of a drill string (29) used in drilling a well (30). The sleeve (20) is restrained from rotating relative to the drill string (29), but can be released and quickly slipped off the drill string (29) in the field to permit rapid replacement if damaged, or if alternate equipment is required. The sleeve (20) carries sensing means (3...

The application of a disc brake is initiated by operation of a pull-rod (21) which is operative to move a pressure plate angularly, in turn to cause the plate to move axially and clamp a rotatable brake disc against a face in a housing. The outer end of the pull-rod (21) is in screw-threaded engagement with a rotatable sleeve (10 min ) which is axially slidable to a limited extent in a further hou...

Improved phenolic foams are produced having a more uniform cell structure, improved mechanical and thermal properties, and improved foam structure by foaming a phenol-aldehyde oligomer condensate such as a resole, an extended resole, or a mixture of a resole and a novolac resin in the presence of N-methyl-2-pyrrolidone.

An electromagnetic sliding shoe brake also referred to as a slipper shoe brake is constructed especially for use in or on rail vehicles, especially high speed rail vehicles. The magnetic core, with its energizing coil, has at least two pole pieces. The sliding brake shoe comprises ferromagnetic pole plates alternating with interconnecting magnetically insulating members. The pole plates, or rather...

The S-cam is carried by a brake shaft 12 (e.g. operated by a spring- loaded cylinder through a rod linkage) and is forced by a spring 1 against a fixed brake carrier 8 to damp out vibrations, which occur when braking, irrespective of the direction of the wheel rotation. As shown a compression spring 1 with hardened faces 9, 10 is provided between a sleeve 2 and an abutment ring 3 to force the brak...
