Abstract: A disposable protective foot pad, composite and its method of manufacture including a resilient planar foam base, an adhesive layer on one side of the base, carried by a film having another adhesive layer on its opposite side covered by a protective sheet. The foot pad composite is manufactured by feeding a web of elastomeric foam in contact with a double-sided film after one of two protective sheets is removed from one side of the film and thereafter simul- taneously die cutting a plurality of protective foot pads from the foam web, film and protective sheet composite.

Abstract: There is disclosed a method for manufacturing a batch of sensors including providing a substrate which has a plurality of conductive tracks formed thereon; electrochemically depositing a first active sensing material layer over the substrate and the conductive tracks in a process in which the conductive tracks are part of a single electrical circuit; removing deposited active sensing material from predetermined portions of the substrate: and sub-dividing the substrate to produce a plurality of sensor units.

Abstract: Multiple streams of digital video data are partitioned into frames of at least two different lengths, where each frame length is an integer multiple times a minimum frame length. Each frame is written into a series of full cells and one or two partial cells. Each full cell carries the same number of video data bits, while each partial cell carries video data bits and/or other overhead bits which together equal the number of video data bits in one full cell. All of the full cells and partial cells for the frames are sent in a time-multiplexed fashion on a communication channel at a single cell rate. A constraint is imposed whereby the different frame lengths are limited to those where the integer multiple of the minimum frame length, divided by the total number of full and partial cells per frame, is a single ratio; and consequently, the video data bits in all of the video streams occur on the communication channel at the same average bit rate, independent of the different frame lengths.

Abstract: A graphics processor uses a line draw facility to receive first and second values indicative of the coordinates of respective first and second end points of a line. The reception of the second value is sensed by the line draw facility and line data is generated responsive to the sensing of the second value.

Abstract: A graphics device includes first and second endpoint memories where coordinates of a line can be stored. State logic within the graphics device calculates line parameters from the first and second endpoints. The calculated line parameters include a line error term which can be stored in an error term memory. The error term memory is writeable from a source external to the graphics device, such as the CPU of a computer system, so that the external source can modify the contents of the error term register.

Abstract: A process for the preparation of cyclopropane compounds which comprises reacting a compound of formula:Y--CH.sub.2 --CNwith a diene of formula:CX.sub.2 =CH--CH=C(CH.sub.3).sub.2in the presence of at least one reducible copper salt, X being chlorine or bromine and Y being cyano, alkoxycarbonyl containing up to four carbon atoms in the alkoxy moiety, benzyloxycarbonyl, phenoxybenzyloxycarbonyl or 2,2-dichlorovinyloxybenzyloxycarbonyl.

Abstract: A programmable sewing machine adapted to learn and store, in Automatic Learn or Key Learn Modes of operation, a series of sewing machine operations for later automatic duplication, in an Automatic Sew Mode of operation, at the same sewing rate as the initial operation, or at the peak sewing rate achieved during each operation; or, in a Control Sew Mode of operation at a controlled lower speed. A software program enables the speed profile of an initial sewing operation to be stored in memory as a number (at least one) of pseudo segments of variable time duration. Each pseudo segment has a fixed sewing speed associated therewith. By applying these stored speed values to a digital to analog converter and applying the resulting voltage to the sewing machine drive motor, the speed profile recorded can be substantially faithfully duplicated.

Abstract: A programmable sewing machine adapted to learn and store, in Automatic Learn or Key Learn Modes of operation, a series of sewing machine operations for later automatic duplication, in an Automatic Sew Mode of operation, at the same sewing rate as the initial operation, or at the peak sewing rate achieved during each operation; or, in a Control Sew Mode of operation, at a controlled lower speed. Additionally, the machine operation may be limited in a Set Up Mode to preset rates for machine speed, copy or peak speed automatic operation, number of start stitches, number of stop stitches, start speed and stop speed. The machine may be operated in the Manual Mode with provision for first tack and last tack and thread trim and wipe when desired. The automatic operation of the sewing machine may be interrupted to go into a Repair Mode during which the sewing machine may be operated manually, and, on proper command, to revert back to the Automatic Sew Mode at the particular operation which was interrupted.

Abstract: A programmable industrial sewing machine adapted to learn and store a series of sewing machine operations for later automatic duplication, in an Automatic Sew Mode of operation, at the same sewing rate as the initial operation, or at a peak sewing rate achieved during each operation; or, in a Control Sew Mode of operation at a controlled lower sew speed. The automatic operation of the sewing machine may be interrupted in order to vary the sew speed, and will revert to automatic operation on operator command where the interruption took place. In the Automatic Sew Mode of operation, stitching may also be interrupted to vary a prior pivot delay time, i.e. a time duration with the presser foot elevated and the sewing needle in a lowered position through a work material. Again, stitching will be reinitiated on operator command at the point at which interrupted.

Abstract: This invention relates to apparatus for the reproduction of graphic material which is capable of operating a photo-composing device for reproducing the graphic material as an image on a photosensitive surface. The apparatus scans the graphic material with a light spot associated with a photosensitive device to produce an electrical output signal modulated according to the graphic information and which is employed to reproduce the graphic information on the photo-composing device. Control means are provided for positioning the scanning light spot at the start of each scan according to predetermined co-ordinates, whereby any scan can be commenced at any desired point on any item of graphic material within the field of scan of the light spot.
