Title: Method and apparatus for tracking a sweeping generator by a frequency selective receiver
IPC: G01R27/28
Filed: 1973-12-21
Abstract: 1457747 Measuring parameters of four-pole networks HEWLETT-PACKARD Ltd 21 Dec 1973 59599/73 Heading G1U In measuring the frequency response of a network 10, a generator 12 provides an input thereto whose frequency is cyclically swept in increments under the control of a programme 16. The network under test output feeds a frequency selective receiver 14 whose operating frequency is controlled by a second programme 18 identical to the first 16. A comparator 20 e.g. a programmable calculator decides:- (a) if two successive receiver outputs at one frequency are above a first defined level and (b) if the ratio of the two successive outputs is below a second defined level. If so, the measurements are displayed and/or plotted 26. If either of these tests is failed, the programme 18 is halted and the receiver 14 "re-locks" when the generator 12 output frequency matches the receiver operating frequency again during the next sweep cycle. If the generator 12 and receiver 14 are controlled by one programme unit (i.e. synchrous sweeping) the described arrangement  ensures that the test frequency is maintained until both the network 10 and receiver 14 have "settled" to the new frequency. One or other amplitude test may be omitted.

Stock from the train 2 is successively fed by a pivotable guide 10 to one of the pipes 12, is coiled in the associated furnace, and immediately uncoiled into a pipe 16 leading into a finishing train.  Each furnace, Fig. 3, works on the Edenborn principle and is provided with a common inlet and outlet guide 42. During coiling, stock enters the guide 42, is fed through two guide rollers 30, and is delivered by a rotary layering pipe 18 into a gas heated chamber 14. Just before the trailing end of the stock enters the guide 42, a sensor 48 (Fig. 2) causes the motor 32 driving the rollers 30 and pipe 18 to be reversed. Simultaneously the guide is turned to the dotted position, and the trailing end (still at rolling temperature) is fed out of the furnace to one of the finishing trains. When all the stock has left the furnace, the guide is turned to its initial position ready for a further length of stock. The speeds of the finishing trains are arranged to be approximately four times slower than that of the train 2 so that the mill can run continuously. The tubes 16 can extend to the inlets of the finishing stands, or can be interrupted, as shown, by cropping shears. In addition to the sensors 48, a sensor 49 may be used for detecting the end of a length of stock and for slowing down the motors 32. Serially connected hydrostatic motors may be used in place of each motor 32.

Abstract: 1300074 Coated sheet material BRITISH UNITED SHOE MACHINERY CO Ltd 15 Dec 1969 [17 Dec 1968] 61028/69 Heading B2E A method of stiffening flexible sheet material of a shoe upper comprises applying a coating of a hot viscous molten mixture comprising a first component comprising a synthetic polymer containing groups reactive with groups of a second component comprising a synthetic polymer, application being before any substantial interaction has taken place, the proportions of the components being such that reaction occurs to form a material not fusible at temperatures effective to melt the original material. The molten synthetic polymeric material may be prepared by mixing two stable components which have been separately melted before mixing, each component being fed in the form of rod to a melting device therefor. The first component may comprise a resin having groups which interact with groups of the second component or the first component may contain groups of a catalyst for reaction of groups contained in the second component with each other inactive at full temperature but which become active on heating. Preferably, the components remain in unreacted condition, after cooling, for sufficient time to permit softening of the applied coating for shaping of the portion of sheet material to which it has been applied, e.g. a toe end portion of a shoe upper, but will then react to form the cured polymeric material. Suitable synthetic polymers are polyamides, polyesters, polyepoxides and polyurethanes, resins containing reactive or catalytic groups or polyamides containing primary, secondary or tertiary amine groups in the polymer chain thereof, such amine groups being readable with epoxy groups of a second polymeric component. Other polymers may be based on isocyanate, carbodiimide and phenolaldehyde.

[Class 38 (iv)] [Also in Group XXXV III] In a system for controlling and maintaining the air flow constant at a predetermined setting for pressurizing aircraft, a butterfly valve 3 is positioned by the movements of a handle q. This handle moves a member l rotating on the same shaft as a permanent magnet 6, and carrying two rigidly mounted contacts k and and two spring-mounted contacts m and n from an equilibrium position in an electromagnetic field h. The consequent closure of one of the pairs of contacts operates solenoid u or t to cause rotor 7 to run and open or close the butterfly valve 3. The air flow then positions a flap valve 4-which operates a transmitter 5 of the ring potentiometer type to step the field around until the contacts part. Should the flow alter from the predetermined value, flap valve 4 alters the position of the contact arm supplying the potentiometer resistance and the resulting field rotation in winding h closes one of the pairs of contacts to readjust the butterfly valve to maintain the air flow constant.
