Title: Chip remover for machine tools
IPC: B23Q11/00
Filed: 1986-03-20
Granted: 1988-07-20
Abstract: Chip remover for machines which perform a machining operation, especially on metallic workpieces, such as strip edging machines, turning machines, etc. The chip remover has a stretched spiral rotating about its longitudinal axis with successive turns spaced apart from one another. The free upper end of the spiral extends into the chip discharge area of the machining tool. This spiral carries the chips away from the area about the tool to assure unhampered machining. The spiral is in the form of a hollow helix and is surrounded, on the outside, with only minimal clearance, by a non-rotating guide tube having an open-topped slot running lengthwise of the tube. The upper end of the helix extends freely out of the tube.

Abstract: Denim fabric is treated (12-20) to raise the warp yarns adjacent the face of the fabric so that they can be rubbed and abraded to loosen the surface fibres; the tips of the warp crimp are subjected to abrading and rubbing (22) to reproduce the surface abrasion of washing and tumble drying without raising a nap or fuzzing the face. The abrading may be sanding using sandpaper in the range of about 50-100 grit, employing a 9-roll T-Ralph sander with 6 rolls running at a speed of about 50 ydm (50 metres/minute). The fabric may be lightly singed (10, 30) before raising which may be done by scouring (32) with a blend of phosphated esters; open-width washing (34) through about 5-10 wash boxes at speeds of about 30-80 yards per minute (30-75 metres/minute); first and second rope washings (36, 38) of about 15-25 minutes each, the first at about 180 DEG F (80 DEG C) and the second at about 140 DEG F (64 DEG C); drying under tension (40); finishing (42) utilizing wetters and softeners; and sanforising (44). After the abrading step (46), the fabric is shrunk (48) to 0.2% warp shrinkage.

Date Jan. 28, 1988.It is foreseen to measure the rotational speed (V) of a motor (4) by measuring the electromotive force (e.m.f.) This e.m.f. is calculated as the difference between the terminal voltage (Va) and the voltage drop at a reference resistor (S), through which the armature current flows, then this value is used as a velocity feedback signal for motor regulation. Particularly, the terminal voltage (Va) is cyclically measured at two successive close instants (t1, t2), during which the armature resistance (Ri) and the motor e.m.f. can be considered constant; these terminal voltage values (Vat1, Vat2) are stored, then elaborated to perform the actual armature resistance (Ri) during that interval (t1-t2), then this value is multiplied for the instant current (I). The result is then substracted from the terminal voltage (Va) and only at that time the resulting e.m.f. is used as a velocity feedback signal for the velocity feedback circuit. The apparatus for carrying out this process is also disclosed.

Title: Rotating actuating device for moving a pivoting door wing, especially at a vehicle
IPC: E05F15/54
Filed: 1988-01-27
Granted: 1990-04-11
Abstract: A rotating drive mechanism for operating the wing of a swinging door, especially of a vehicle. The wing is articulated by pivoting arms to a rotating post, which it rotates along with. When the door is closed, the wing can be raised by axial displacement of the post into a locked position, where locking components on the stationary door frame and on the wing of the door engage each other. The post is driven by a strictly linear mechanism that is controlled by pressure medium and its linear motion is converted into a rotation by a helical transmission. Certain drawbacks are elminated by the improvement wherein the rotating post is coupled to the helical transmission in such a way that, at least while the wing of the door is closing, the post cannot rotate in relation to it but can move axially and, once the post has attained a specified limit of rotation while the wing of the door is closing, the linear drive mechanism will be additionally directly coupled axially to the rotating post in such a way as to lift it.
