Abstract: Welder's protective goggles particularly adapted for operators who must use corrective bifocal lenses in their work. The goggles comprise a generally tubular shaped member, having an open end contoured to fit snugly against the face about the eyes of the wearer. The axis of the open end of the tubular member is on approximately the same horizontal plane as the axes of the eyes of the wearer when looking straight ahead. The tubular member also has a closed viewing end which has at least one viewing aperture adapted to receive a safety lens. The axis of the closed viewing end intersects the axis of the open end at an angle from below it. The degree of the included angle formed by the intersecting axes is predetermined so that the tilt thus given to the closed viewing end in relation to the open end is such that the wearer of the goggles when using corrective bifocal lenses underneath them will have an unobstructed view when looking through either corrective section of the bifocal lenses.

Abstract: A sewing machine, or similar machine which consumes thread at a work station, has combined with it a thread color device located between the work station and a thread supply. The color device causes the thread issuing from it to have any one of a number of available colors, allowing stitches of different color to be made at the work station without changing the thread or rethreading the needle. The timing of a change in thread color at the color device with respect to the schedule of work performed at the work station, and the movement of the thread from the color device to the work station, are controlled so that a change in thread color occurs at the work station at substantially the same time as such change is desired in the work schedule performed at that station.

Abstract: Pushbuttons for controlling pattern sewing in a sewing machine are provided with latch plates which prevent the simultaneous retention in actuated positions of pushbuttons for selecting bight controlled patterns and pushbuttons for selecting combined bight and feed controlled patterns, and which are disposable to permit the retention in actuated positions of pushbuttons in either one or the other of said groups.

Abstract: A unitary transparent eyepiece has a planar outer rim and a planar inner viewing zone, the plane of the inner viewing zone being inclined at an angle to the plane of the outer rim.The angle between the, preferably circular, inner viewing zone and the, preferably circular, outer rim of the eyepiece is chosed such that when the planar outer rim is fitted into the planar socket of a face-piece in a protective device, the inner viewing zone is orthogonal to the line of forward vision of the wearer. In this way the face piece conforms to the shape of the wearer's head, an efficient planar and circular seal is obtained between the eyepiece and its socket, and optical aberrations (associated with curved eyepieces) are minimized.The position of the inner viewing zone relative to the outer rim may be varied according to the clearance required between the eyepiece and the wearer's eye and the type of face piece employed.

Abstract: Ski goggles are composed of goggle frame, goggle lens and rubber band. Vent holes are formed, respectively, in the top peripheral wall portion and the bottom peripheral wall portion of the goggle frame. A permeable coating material is engaged to cover the vent holes. A mounting stand, which serves as duct, is engaged in the central portion of the top peripheral wall portion of the goggle frame. A ventilating fan and a small-size motor for driving the fan are mounted on the mounting stand. The ventilating fan is adapted to compulsorily ventilate the air within the inner space formed between the goggle lens and the face, and is accommodated within the mounting stand. The motor can be turned on or off by a power supply switch. The number of the revolutions can be controlled by the controlling circuit or can be controlled by a controlling circuit or in accordance with the humidity of the inner space.

Abstract: A programming device for an automatic sewing machine wherein a succession of stitches are formed along a desired stitching line registered via a stitch pattern record medium according to a batch of sewing instructions.

Abstract: A computer controlled pattern stitching machine includes input means 30 for supplying BCD X and Y-axis scaling signals to enlarge or contract a pattern to be sewn, control means 28 including a CPU 58, a RAM 60 and a memory 62, and drive means 32 including X and Y-axis stepping motors for moving a gripped fabric relative to a needle bar in response to signals from the control means. The stepping motors 42, 44 drive respective timing belts 66, 78, and belt 66 carries orthogonally mounted X and Y-axis rail members 70, 84 on which a cloth holding device 68 is secured.

Abstract: This invention relates to a helmet for cyclists, skateboard runners and roller skaters. It comprises a shell of flexible and hard plate-shaped material and a damping means attached inside the shell. The shell in its plane has the form of an I, with extended cross-pieces (3) and with tips (3) attached radially between the same, which tips extend from the connecting between the cross-pieces and the stem of the I. About at the center of said stem lateral tips are attached to both sides. The cross-pieces and tips are provided with attachment means in such a manner, that the free ends of one cross-piece after the bending of the stem can be connected to the free ends of the other cross-piece. The free ends of the tips can be attached to suitable holders on the lateral tips.The cross-pieces, tips and lateral tips can be designed as bands, and the attachment means be arranged so that the width and size of the shell can be adjusted.
