Abstract: The process device for the photogrammetrical measurement of the human head, especially of the middle region of the face with the eye sockets, the nose, the check bones and the brows, is comprised of a projector for projecting a pattern image onto the face and two cameras which can simultaneously take two pictures from two different directions of the face and head with the pattern image projected on it. The two cameras and the projector are supported by an apparatus carrier, which can be moved in a vertical direction relative to a base permanently connected to the device and in at least one horizontal direction. This minimum of one direction coincides with the optical axes of the cameras. The device will facilitate bringing both the projector and the cameras on the one hand and the human head on the other into the required relative position to one another as necessary to take the pictures.

Abstract: A dosing apparatus for packaging containers comprises a dosing device including a housing, a wall within the housing and reciprocable to draw in and expel a substance through an inlet and an outlet, respectively, of the housing, a rotary stepping motor which drives the wall, and a screw device which converts rotary motion of the motor to linear motion of the wall; and a control programmable to control the speed and stroke angle of the motor. The filled containers may be weighed in turn and the weight data used automatically to make any necessary corrections to the wall stroke.

Abstract: A method of forming a skived edge on the inside panel of a thermoplastic coated paperboard container, in part while the container is part of a web or sheet of paperboard material, and in part on individual blanks after being cut from the web or sheet. More specifically, a partial depth cut and an adjacent score line are formed on a carton converting machine providing a precise location for subsequently removing material and folding the edge of a blank on a side seam sealing machine.

Abstract: A temple end piece for a temple of a spectacle frame has a unit stable in a form composed of an essentially horizontal first segment and a second segment curving downward to the rear in the shape of an arc. Connected to this unit is a third segment formed by a soft, flexible band, the upper end of which is attached to the first segment and the lower end of which is permanently connected to the lower end of the second segment. This band extends in the uncharged state of the temple end piece curved essentially in the shape of an arc, in fact, in a manner similar to the second segment. In its longitudinal direction the band is neither stretchable nor compressible. By virtue of its high flexiblity the band fit the shape of the auricle and/or head of the spectacle wearer when the spectacles are worn in place, so that a large contact area with lower pressures will adjust itself, and any and all pressure points are prevented in this contact area.

Abstract: In the case of a hinge for the connecting of a temple shaft with a hinge piece of a spectacle frame, at least one hinge eye is located on only one of these elements (the hinge piece or the shaft of the temple). The hinge pin running through this eye is designed in one piece with the other element (the shaft of the temple or the hinge piece). For this purpose, either the hinge pin of plastic is injection molded into the opening of the hinge eye or the hinge eye of plastic is injection molded around the hinge pin. In this case, one preferably proceeds in such a manner that one of the two elements with the associated hinge eye or hinge pin is formed first and that this initially formed element forms a part of the surface of the cavity of the injection molding tool for the other element such that the other element is injection-molded directly onto the initially produced element.

Abstract: In order to avoid foaming which may influence the closing zone of containers for products of the kind that may foam during the filling procedure, a method is provided according to which an anti-foam medium in the shape of a thin surface layer is applied in the closing area of the container, or container blank, resp., if desired, close to said area on the inner surface of the container. Such application is preferably carried out before the blank is set up as a container. A device for use in the method may comprise a roll (12) provided with one or a number of grooved zones (9',10'). Roll (12) is mounted on a shaft (13) to be rolled in contact with the inner surface of a web (11) from which the container blanks are manufactured, preferably while said web is advanced past roll (12).

Abstract: Described is a device for testing for a perfect fit of spectacle frames on the head of the spectacle wearer. The device has at least one plate- or blade-shaped force or pressure sensor, which is mounted on a holder and can be applied to the respective contact surfaces between the frame and head. With this device it is possible to make precise measurements of the forces and pressures actually occurring at each individual point so that they can be reproduced, for example, by raising the frame slightly, introducing the pressure sensor to the pertinent point of contact, and lowering the frame down again. Becausede of the negligible structural height of the pressure sensor, the individual contact areas between the frame and head can be tested without having to make any change in the controlled vane position in space existing when the spectacles are worn in place.

Abstract: A temple end piece for a temple of a spectacle frame is comprised of a first segment running essentially straight in the longitudinal direction of the temple, a connecting segment extending downward from the first segment, and a fitting segment intended for fitting on the head and/or behind the ear. The longitudinal fitting segment is borne and supported by the connecting segment, whereby this support is achieved at the longitudinal middle or at the lower end or in the region between the longitudinal middle and the lower end of the fitting segment, so that at least the upper half of the fitting segment projects freely upward to the first segment and can be deflected elastically in the direction toward the connecting segment. This capability of an elastic deflection is furnished by a suitable choice of material, as, for example, a suitable plastic material, and/or specially designed elastic regions.

Abstract: The present device for the photogrammetrical measurement of the human head, especially of the middle region of the face with the eye sockets, the nose, the cheek bones and the brows, is comprised of a projector for projecting a pattern image onto the face and two cameras which can simultaneously take two pictures from two different directions of the face and head with the pattern image projected on it. The two cameras and the projector are supported by an apparatus carrier, which can be moved in a vertical direction relative to a base permanently connected to the device and in at least one horizontal direction. This minimum of one direction coincides with the optical axes of the cameras. The device will facilitate bringing both the projector and the cameras on the one hand and the human head on the other into the required relative position to one another as necessary to take the pictures.
