Patent EP-0091514-A3 (EP)
Title: Protective light filter, in particular for protective shields or welding glasses
IPC: A61F9/06
Filed: 1982-11-26
Abstract: An electro-optic welding lens assembly for the use in a welder's helmet or protective eyeshield comprises a filter arrangement with at least one liquid crystal light shutter element and a control unit for changing the transmission rate of the filter assembly in response to ambient light conditions. The light sensing element used to control the transmission of light through the filter arrangement is simultaneously an opto-electric transducer, supplying power to the control unit and the light shutter element. Thereby, there is no need for an additional power supply like a battery. If the sensing and transducer element is arranged behind the light shutter element, a self-regulating loop can be realized to continuously vary the transmission rate of the filter arrangement and thereby to keep the viewing illumination through the lens assembly essentially constant.

IPC: B29C53/00
Filed: 1982-04-16
Abstract: Apparatus for making side-sealed bags (22.1, 22.2, 
22.3) from a double-layer web (22) of thin synthetic 
plastics film. The apparatus includes a rotatably moun­
ted sealing drum (14) having a plurality of circumfer­
entially spaced axially extending slots (16) in its peri­
phery. In use, the web (22) moves belt-fashion over the 
slots (16) in contact with the drum (14). A sealing rotor 
(18) running in synchronism with the drum (14) has a 
heat cutter member (20, 21) which intersects the web 
(22) at circumferentially spaced intervals by passing 
cyclically into the slots (16) of the drum (14). The heat 
cutter member (20, 21) has spaced interruptions (21.2) 
along its length which result in spaced perforations 
(160.1) being made across the width of the web (22). 
The two layers (22.11, 22.12) of film are welded together 
at such perforations (160.1), thus forming side-sealed 
bags separated by zones of weakness (160). The web 
(22) is rolled up into a roll (26) of such side-sealed bags 
(22.1, 22.2, 22.3). The sealing rate and web speed can 
be adjusted to match the rate of extrusion of an ex­
truder (242).

Abstract: A portal frame structure is provided comprising a 
horizontal truss (10) and vertical supports (11, 12) se­
cured to the respective ends of the truss (10), the truss 
(10) being provided with a joint arrangement (13) inter­
mediate its end, said joint arrangement (13) being such 
that outside elements (15, 16) of the truss (10) on one 
side of its neutral axis (X-X) are maintained in com­
pression in both directions of load on the truss, and 
that outside truss elements (18, 19) on the other side 
of said neutral access are subjected to predetermined 
tension, such that as the load increases in one of said 
load directions the tension is reduced, and to tension 
exerted in the other of said load directions. The pre­
determined tension may be zero, such that the joint 
arrangement collapses immediately a compressive load 
is applied. Alternatively, it may have a value such that 
it reaches zero at any point up to the maximum designed 
load for a particular building application. The portal 
frames are for use with cladding secured to the inner 
side of the frames.

substance being tested for; characterised in that reaction 
ingredients (a), (b) and (c) are all mixed in a single step for 
reaction in a single reaction liquid, and competitive interfer­

Title: Device for loading a grinding machine for cleaning castings
IPC: B24B41/00
Filed: 1987-01-23
Abstract: A manipulator (3) for moving rough castings relative to a grinding unit is provided on a grinding machine for cleaning castings. The object is to automatically feed the castings (29) to the manipulator (3) in a simple manner. For this purpose, a track consisting of two guide rails (13) is run around the manipulator (3) and is interrupted in its working space (4). Pallets (14), guided on grooved rollers (26), are moved on the track by a friction drive lying below the guide rails (13). In a work-holding fixture (31) designed as a negative cast, the pallets (14) each carry a casting (29) which is only loosely inserted. The clamping of the casting (29) for the machining is effected by the manipulator (3) in a unit with the pallet (14). For this purpose, clamping bolts (23) are provided in the pallet (14) which are used for reception in the manipulator (3), carry the grooved rollers (26) and also hold the work-holding fixture (31). The manipulator (3) pulls the clamped unit of pallet (14), work-holding fixture (31) and casting (29) off the guide rails (13) and also puts them on the guide rails (13) again after the machining. The tool change and the expansion of the system, owing to its simplicity, are possible without problem and with little expense. <IMAGE>

Abstract: A light valve of the Schlieren dark field 
type is provided with a vacuum envelope containing 
an electron gun, a focus and deflection assembly 
and a rotating disk coated with a light modulating 
fluid on which an electron beam from the electron 
gun is scanned in a raster pattern. The rotating 
disk has a transparent electrode which serves as 
an electron beam landing electrode. Between the 
focus and deflection assembly and the rotating 
disk is a drift ring assembly comprising at least 
two axially separated segments. The drift ring 
segment closest to the focus and deflection 
assembly is operated at a voltage to generate, in 
combination with the focus and deflection 
assembly, an electrostatic lens which corrects 
distortions that originate from deflection fields 
applied to the focus and deflection assembly. The 
other drift ring segment is operated at a voltage 
different from that of the first drift ring 
segment such that the two drift rings interact to 
generate an electrostatic lens that controls the 
focus of the electron beam. The second drift ring 
and the electrode on the rotating disk interact to 
generate a third electrostatic lens to further 
control beam size to an essentially uniform value 
by further shaping of the locus of deflected field 
focus to closely approximate the planar surface of 
the control layer.
