An electromagnetic valve assembly having upper and lower modules. A standardized lower module can be joined with one of several upper modules having a different axial length for varying the magnetic field strength of a coil arrangement in the upper module without changing the length or position of an armature tube in the lower module.

An electromagnetic valve assembly having a valve unit with a valve seat and a coil arrangement. An armature is slidably disposed in the bore of the coil arrangement. A yoke unit surrounding the coil arrangement is in two parts having cooperating longitudinally extending edges forming two axially extending air gaps on diametrically opposite sides of the yoke unit. End flange portions of the two par...

An X-ray diagnostic apparatus is to be provided which permits the taking of X-rays on the bed, without its being necessary to lift the patient in order to push an X-ray film cassette (9a) underneath. The intention is that the X-ray film cassette (9a) should be simply and accurately centred relative to the X-ray source (13). The bed has two supporting surfaces (1, 4), of which the upper one ca...

A proportional magnet (11) is proposed which has an energising coil (42) and a control coil (43) which is arranged concentrically with respect to the said energising coil and has the same number of turns. Each coil (42, 43) has inherently separate inputs and outputs for the power supply. In consequence, the inductance of the coils (42, 43) can be reduced for the same lifting force, as a result of ...

A battery grid pasting machine has an endless steel conveyor belt (80) for advancing grids beneath a paste hopper (132). The lower end of the hopper is closed by an orifice plate (170). The top run of the belt is supported by a vertically adjustable roller (82) directly beneath an orifice slot (194) in the orifice plate (170). A guide assembly is provided for advancing the grids in a downwardly in...

Equipment fitted to a ringspinning frame enables spinning on to be commenced automatically. A device enables a loop of yarn to be made at or near the spindle, to engage on a tube, or cop, with several turns. ADVANTAGE - The method is adaptable to requirements, eliminates the need for manual operation, is reliable in use and economical to install.

The valve actuator has two electromagnets opposite each other in the axial direction. These have ring poles (4,5). An armature (6) is attached to the valve shaft and moves inside the poles (4,5) in the axial direction. The ring poles (4,5) are dish-shaped with concentric wedges (11). These define a cylindrical chamber for the armature (6). ADVANTAGE - Allows quick and accurate valve switching and ...

A device prints round pipes, and partic. plastic pipes such as those for carrying gas, and uses shells which grip the pipe; the shells concerned join together to form a sleeve and can then be sepd. again by the device. The example (R) shown has two pincer-like arms (1,2) connected (3), whereby one end has the spreader arms (4,5) and the other end has the gripping pincers (6,7). Each of the latter ...

The bed consists of a trough (1) into which is packed a foam or soft rubber mat (4) which is waterproof. A support (6) for lifting the top part of the body is inserted. A large, thin sheet (3) which breathes is placed on the base and has a covering which breathes on its upper side. The ends of the covering hang loosely on all sides of the trough's rim and are fixed in place by a cover. A filler pi...

The solid bowl worm centrifuge is used to separate a 2-phase liquid mixture containing solids. The product to be separate is taken to a drum (1) via an intake pipe (11), passes via an intake aperture (10) into a distributor pipe (7) which rotates with a worm (2) fitted in the drum (1). In the distributor pipe (7) the product is accelerated to the rotation speed of the worm and then passes through ...

Via an input device 12, data on the two-dimensional mass distribution of a printed sheet 3 is supplied to a control device 11, which controls the pressure to be distributed by a blowing-air or suction device 9 acting on a sheet being added to stack 4, the pressure distribution correlating with the mass distribution. The mass distribution is determined by the arrangement of ink, varnish dampening m...

2127711 9313917 PCTABS00024 A rotary cutting die assembly (10) comprised of a mandrel (12) adapted to be rotatably mounted in a rotary die cutting press, and a cylindrical cutting sleeve (14) and drive gear (16) slip fit over the mandrel (12), provide apparatus for replacing the cutting edge (36), (38) of a rotary cutting die at a reduced cost for materials, manufacturing and shipping than that as...

To reduce the occurrence of false alarms, the disclosed system incorporates an auxiliary sensor (8) for detecting the presence of a shopper passing through the electronic article surveillance device (1), such that the device is operated continuously, and the auxiliary sensor (8) is used to enable external alarms of the device only upon detecting the shopper's presence. Thus, while the device conti...

A method of making a polyethylene terephthalate/polyolefin blend for sheeting and thermoformed articles which has improved color stability and can be recycled many times. A heat stabilizer is melt blended only with the polyolefin prior to its incorporation into the polyethylene terephthalate. The PET and polyolefin are then blended and extruded into sheeting and subsequently thermoformed into arti...
