Abstract: 1,126,026. Forming fibre webs, non-woven fabric. IMPERIAL CHEMICAL INDUSTRIES Ltd. 21 Dec., 1966 [6 Jan., 1966], No. 665/66. Headings D1F, D1N and D1R. A non-woven fabric is made by forwarding a bundle of continuous filaments 38, see Fig. 1, under tension through a banding device 10 wherein they are aligned into parallel relationship as a ribbon, forming this ribbon into a diverging curtain of separated filaments, then overfeeding this curtain onto a receiving surface as it moves at right angles to the plane of the curtain thus forming the web. The banding device can comprise at least two non-parallel slots 18, and 22 with or without slot 20, covered by a plate (12) (see Fig. 2, not shown) so that streams of gas, e.g. air, passing through the slot align the filaments into the ribbon. The width of the ribbon can be regulated by adjustment of the air flow to the slots. Modifications of the shape and positions of the slots is illustrated in Figs. 3 and 4, not shown. The spreading device 40 which forms the filaments into the curtain can have a slot 44 which subjects the ribbon to a gas stream of arcuate cross section. The spreading device has an impingement plate (48), see Fig. 6 not shown, which may be adjusted so as to vary the width of the web. The web width may also be varied by adjustment of the relative positions of the banding device spreader and receiving surface. The filaments can be drawn or undrawn, or a mixture thereof can be used. The filaments can be heat-set during drawing. The filaments can be drawn before or after banding the filaments into a ribbon. The filaments can have any electrostatic charges removed by D.C. eliminators 58. mounted on either side of the running filament, see Figs. 7-10 not shown. The filaments can be made from polyethylene terephthalate, polyhexamethylene adipamide, polycaprolactam, polypropylene, dry viscose, cellulose acetate, acrylics and heterofilaments of various compositions. The filaments can be crimped. Binder filaments of lower melting point can be present, e.g. polyethylene isophthalate terephthalate copolymer. The web can be heated to bond the filaments, e.g. using hot calendering super-calendering.

Title: Interactive electronic thermostat and use thereof
Inventor: BERKELEY ARNOLD D
IPC: G05D23/19
Filed: 1997-02-27
Abstract: An interactive electronic thermostat operates to communicate with an installed through an audible or visual display and keypad to instruct the installer to perform tasks and enter observations to effect proper connections at the thermostat of heater/air conditioner wires in spite of the absence of labels identifying the functions of those wires. The thermostat requires entry of coded indicia representing operator-observed conditions in the system in response to displayed instructions carried out by the operator. Control circuits are automatically assigned functional tasks in response to the operator-observed conditions entered into the system. Different program routines are invoked depending upon the number of system wires and the type of heater/air conditioner being controlled. Under appropriate circumstances, messages are displayed informing the operator/homeowner that the thermostat is incompatible, or has no advantageous use, with the heater/air conditioner. In one embodiment the installer need only connect the wires to the thermostat terminals one time; the thermostat reconfigures its internal connection paths in response to installer-entered indicia to assure proper control of the system.
