Title: Applying liquor to a textile web
IPC: D06B23/00
Filed: 1978-12-01
Abstract: Liquor is continuously applied to a textile web T by an applicator roll 13, the web being under vacuum before, during, and after its contact with the applicator roll. The applicator roll 13 is partially immersed within a liquor bath 12 in a vacuum chamber 10 and through which the web T passes. When the web emerges into the ambient atmosphere, the pressure of the latter forces into the web the small quantities of liquor applied to the latter by the applicator roll. The vacuum chamber may be sealed by an air-impermeable roller 4 which the web touches or is wrapped on. The vacuum chamber may contain a second liquor bath and applicator roll, so that liquor is applied to both sides of the web (fig. 2). The applicator roll may bear against the sealing roller 4 (fig. 3) the web passing between them and being wrapped on the sealing roller. <IMAGE>

Title: Electrochemical Measuring System
IPC: G01N27/403
Filed: 1979-01-05
Abstract: An electrochemical measuring system which determines selected substances in a sample solution is provided. The system includes a cell which is constructed for simultaneous measurement on at least two electrodes of at least two electrolytic potentials with reference to a reference potential. In a preferred form the cell comprises a hollow, cylindrical body formed of an electrically insulating material. The electrode is open at least at one end and has a generally smooth cylindrical inner surface. A plurality of electrically discrete active electrode segments are mounted on the inner surface of the electrode with their active surfaces substantially flush with the generally smooth cylindrical inner surface. Completing the electrochemical measuring system are a stirring means for creating a relatively high degree of mixing adjacent the electrode active surfaces, means for charging liquid samples to the cell, and means connecting at least two of the electrically discrete active electrode segments to different electrical potentials. In use a sample to be tested is charged to the cell, and stirring is commenced. One of the electrode segments is held at a potential at which a selected substance of interest and also one or more interfering substances responds, while another of the electrode segments is held at a potential at which only the interfering substances respond. The presence of a substance of interest can be determined by subtracting the signals from the one and another electrode segments, and its quantity determined by integrating the signal difference. <IMAGE>

Title: Castors
IPC: B60B33/02
Filed: 1979-07-02
Abstract: A castor has a hollow body (1) which contains a stopper (25) engageable with the inner rim (13) of a wheel (6). To unlock the stopper, a pin (26) carrying the stopper (25) is pressed downwardly and is held in an unlocked position by frictional engagement with the edge of a hole (24) formed in a plate member e.g. leaf spring (18) which is inclined to the axis of the pin (26). Thus, the pin (26) is retained in its unlocked position even when the pressing force is released. One end of leaf spring (18) is connected to a lock pin (22) and to return pin (26) to its locked position lock pin (22) is depressed to release the frictional engagement between the leaf spring (18) and pin (26), the latter returning under the force of compression spring (28). The pins (22, 26) extend through respective windows (21, 27) in body 1. As shown, stopper (25) has engaging portion (29) to engage between gears (14) on rim 13; alternatively engagement may be frictional by means of rubber plates. Plate member (18) may be rigid plate hinged to body (1). Locking pin (22) may be integral with free end (20) of leaf spring (18). <IMAGE>
Patent GB-2027945-A (GB)
Title: Looms having electronic control systems
IPC: D03D51/00
Filed: 1979-08-07
Abstract: In a loom, an encoder (12, 13) is provided on the main shaft (4) to indicate continuously the main shaft angular position. The angular position is fed from the encoder to an electronic decoder (16). A number of lines (18 to 23) each programmed to become energised at a specific main shaft angular position is accommodated in a pegboard matrix (17). When the main shaft reaches a programmed angular position, a corresponding actuating element (26 to 31), e.g. a solenoid valve for a weft insertion nozzle (6, 33 to 41), is actuated by each line. It is thus possible to actuate a relatively large number of components of the loom at each required main shaft angular position. The time of actuation within the loom cycle, or the duration of the actuation, e.g. the time during which an air nozzle is open, can be readily adjusted during operation and hence adapted to requirements at any time. <IMAGE>

Title: Data input device for an electronic diary watch
IPC: G04G99/00
Filed: 1980-08-08
Abstract: The data input device permits the selection of a symbol amongst a set of N symbols, e.g. for memorizing a message. A data input device permitting selection of a particular symbol from amongst a set of N symbols includes a display subdivided into K distinct display zones and K selecting elements, each K selecting element being associated with a specific one of the K distinct display zones. The device may be used, for example, in an electronic diary watch to select alphanumeric symbols and thereby record a message for use in the diary mode of operation. A microprocessor connected to the display and selecting elements first causes the set of N symbols to be divided and displayed equally among the K distinct display zones upon manual actuation of a data selection switch. Subsequently, manual actuation of one of the K selecting elements causes the microprocessor to select the symbols of the distinct display zone associated with the actuated selecting element; these selected symbols are equally distributed and displayed among the K distinct display zones. This selecting process is repeated until the desired symbol is isolated and displayed in one of the K distinct zones, at which point manual actuation of the selecting element corresponding to that particular display zone causes the microprocessor to select and memorize that desired symbol. This selecting process is then repeated for each symbol of the message to be memorized.

Title: Fire retardant roofing material
IPC: C04B20/10
Filed: 1978-07-10
Abstract: Intumescable particles having particular use in asphalt roofing material which is to be made fire- retardant have soluble silicate glass at their cores and carry a protective moisture-resistant coating. This increases the life of a roofing material in which they are incorporated, and also makes possible convenient manufacture of the particles. The protective coating includes an ingredient that is ionized in the presence of water to provide metal cation capable of reacting with the silicate ion of the particle core to form a reaction product that is less soluble than the silicate glass of the core. The coated particles are also useful as fire- retardant additives in many other products, including polymeric articles, sheet materials, and coating compositions.
