Patent GB-2023188-A (GB)
Title: Textile Dyeing Process
IPC: D06P3/00
Filed: 1979-06-12
Abstract: A continuous process for dyeing a fibered or tufted textile e.g. carpet 12 includes the step of applying 19 a viscous, water soluble colorless gum layer over the tufted face of the carpet. Drops of first and second dyes less viscous than the gum are applied 30, 32, over the gum-wetted carpet face. A third dye, which is substantially less viscous than the gum and then the first and second dyes, is applied 46 over the entire tufted surface of the carpet. The carpet may be pre-wetted 14 before the gum layer is applied. Pleasing color effects are obtained due to the differential viscosities and hence penetrations into the fibers or tufts. <IMAGE>

Title: Improvements in or relating to data processing systems
IPC: G06F11/10
Filed: 1979-11-16
Abstract: In an array processor consisting of a plurality of data processing elements (PE), parity processing elements (PPE) hold parity bits for checking the contents of the internal resistors (Q, C) and internal stores (S) of the data processing elements and perform substantially the same operations on the parity bits as the data processing elements perform on the data. However, some of these operations may invalidate the parity bits. In particular, the carry result from an addition operation is not always valid. A parity valid logic circuit (22) is therefore provided to generate a signal (PV) which indicates whether the parity bits (P) from all the parity processing elements are valid, and hence whether the parity check performed using these parity bits is valid. <IMAGE>

Patent GB-2080000-A (GB)
Title: Data Transmission System
IPC: H04L7/00
Filed: 1980-07-10
Abstract: Four wires, namely: a serial data line 10, a wire 11 for clock purposes, a power supply line 12, and a common return 13 connect remote points (POINT 1 to POINT N) to a central control. At each remote point input data is converted by a data converter 15 into a logic-based signal which is loaded sequentially onto the serial data line 10 by a shift register 16. This loading is controlled by counters 17 which count clock pulses on the clock wire 11, and an 0 detector 18 which detects signals on the data line 10. The counter 17 of POINT N initiates the loading of that point's data signal on to the serial data line 10. When this signal reaches the next point down the line 10, the 0 detector 18 orders the shift register 16 there to load the line 10 with its information, before that which is upstream, so the information is in sequence on the data line 10. <IMAGE>

Patent GB-2085399-A (GB)
Title: Robotic manipulator
IPC: B25J17/02
Filed: 1981-10-02
Abstract: A robotic manipulator has three nearly extensible arms 50, 54, 58 mounted on a frame 10 in a triangular array and carrying at their remote ends a connector interface 62 coupling the arms to a tool for manipulating parts to be positioned or for other work. The structure is such that the location of the connector 62 is determined solely by the lengths of the arms 50, 54, 58, while its orientation is determined primarily by the angular rotation of the arms, thereby minimizing the computation required to accurately position a tool. The driving motors, such as 36, for the arms, such as 50, are located at the arm ends adjacent the frame 10; this minimizes the mass, and thus the inertia, located at the connector end, and enables high acceleration and rapid motion of the connector head and its associated tool. Further, a three-point suspension for the arms provides high stiffness enabling the system to carry substantial loads at high speed and with good positioning and orientation accuracy. <IMAGE>
