Title: Combined knob and permutation lock assembly for door latches
IPC: E05B37/02
Filed: 1976-06-09
Abstract: A permutation lock assembly incorporated into a door knob and latch mechanism mountable in the standard openings in conventional swinging doors, using conventional door latch hardware.

Title: Carpeting dye transfer process - uses carrier bands joined with displaced patterns to compensate for shrinkage
IPC: B41F16/02
Filed: 1978-05-12
Abstract: The transfer printing process for textile fabrics, such as carpetings or wall coverings, uses a continuous fabric and a continuous inert carrier for the dyestuff to be transferred by heat and pressure to one side of the textile. The carrier is composed of long patterned strips which run across the carrier and are joined together, and before the carrier is brought to the fabric the sides are joined to two adjacent carriers. The patterning on the side carriers is displaced from the central carrier by a value which is at least the sum of the anticipated shrinkage between one carrier and another in a lateral direction under process temp. When heat and pressure are applied to transfer the dye pattern, the patterns in the carriers join exactly. The process allows broad carpetings and other materials, of 4-5 m width, to be patterned by a transfer dye technique.
