Title: Shoe cover
IPC: A43B3/16
Filed: 1966-12-19
Abstract: 1,102,640. Boots &c. CONVERTORS Inc. 19 Dec., 1966 [6 July, 1966], No. 56762/66. Heading A3B. A shoe disposable cover consists of two side sections 10, 11 which are joined together along their bottom edges 14, front edges 15 and the front portion of the top edges 16 to form a pocket which is open at the top and rear, and two upstanding wing portions 22 which extend forwardly around the wearer's ankle to hold the cover on the shoe. In use the wearer places his shoe in the forward region 27 of the shoe cover, folds the rear portion 28 upwardly to form the heel end of the cover (Fig. 1) and wraps the wings 22 around his ankle, the wings being secured together by coatings 25, 26 of pressure sensitive adhesive. The cover may be made from paper and the two halves may be jointed together by a line of stitching 21 or by adhesive (not shown). The cover may include a strip of conductive tape 13 to earth the wearer as shown in Fig. 1.

Title: Improvements in navigational aids
Inventor: SWALE ROY THURSTON
IPC: G01C21/12
Filed: 1968-12-03
Abstract: 1,240,503. Navigational aids for aircraft. DECCA Ltd. 10 Oct., 1969 [3 Dec., 1968], No. 57292/68. Heading B7W. [Also in Division G1] A navigational aid for indicating in two orthogonal directions the position of an aircraft is provided with a display device, which may comprise a chart 19 movable in one direction (X) and an index 18 movable in an orthogonal direction (Y). Pulses, each representing a unit of distance, are fed from transducer 10 at a rate proportional to airspeed to a resolver 11 which also receives signals from a compass 12, so that the output on lines 170 and 180 represents the components of the airspeed in the X and Y directions respectively. These signals are passed via synchronizing circuits 17 and 18 to drive units 15 and 16 which control the display device; further signals indicate the sense of each component of the airspeed. A clock oscillator 23 provides pulses, each representing a unit of distance, at a constant rate which corresponds to a velocity greater than the maximum expected wind velocity. These pulses are fed to binary dividers 24 and 25 which are associated with " wind stores 26 and 27 respectively, which are bidirectional binary counters, each of which stores a binary digital signal proportional to the component of wind velocity in the corresponding direction. The wind stores control their respective dividers by means of diode matrices 28 and 29 so that the output signals on lines 171 and 181 represent the components of wind velocity in the X and Y directions and serve to correct the movement of the display device so that it will more truly show the position of the aircraft. If the value stored in the wind stores 26 and 27 is incorrect then the position shown by the display device will be incorrect by an amount proportional to the average error in wind velocity and the duration of the error. At intervals therefore the position indicated is compared with the true position, as determined for example by reference to radio navigational beacons, and pulses are fed from the oscillator 23 via control gates 37 and 38 to the display device. The number of pulses produced by the oscillator is divided by divider 36 by a factor inversely proportional to the time since the last adjustment (as measured by counter 33), so that the number of pulses required from the oscillator corresponds to the error in wind velocity since that adjustment, and so that this signal, fed via control gates 39 and 40, corrects the values stored in the wind stores 26 and 27.

Abstract: 1458208 Bulked, blended yarns and fabrics; finishing fabrics NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 17 Dec 1973 [15 Dec 1972] 58296/73 Headings D1F, D1P, D1S and D1W Bulked, blended yarns are produced by subjecting a blended yarn consisting of flax fibres and non-shrinkable synthetic fibres to a swelling treatment in which the yarn undergoes a tensionless shrinking such that the flax fibres shrink by up to 35%. The bulked yarn may then be woven or knitted into a fabric which may be subjected to a synthetic resin treatment to improve its crease resistance. Alternatively, the swelling treatment is applied to a fabric made of the blended yarns and sufficiently loosely woven that in the wet state during shrinkage no tension arises in the fibres. The swelling may be carried out using a 15-24% caustic soda solution or humid hot air. The synthetic fibre in the blend is preferably a polyester. Treatments of fabrics woven from 50/50 flax/polyester blend yarns and 100% flax (comparative) are given.

Filed: 1972-12-29
Abstract: 1409310 Measuring voltage FERRANTI Ltd 27 Dec 1973 [29 Dec 1972] 60099/72 Heading G1U In a measuring circuit, a transducer 11 e.g. a resistance bridge or a potentiometer provides an output signal which is integrated 15 to provide a linearly rising or falling voltage, the sense depending on the polarity of the transducer supply voltage, to one input of a comparator 16 whose output is of constant magnitude but changes in polarity when the integrator output exceeds in magnitude the fraction of the comparator output fed back to its other input. This fraction is held constant in amplitude by the diode bridge arrangement 17 including a Zener diode load 18 and the voltage across the bridge is used to supply the transducer 11. As the comparator output reverses, the transducer output reverses, inverting the slope of the integrator output. The signal at terminals 21 is thus a square wave whose repetition frequency is dependent on the transducer output voltage and thus on the resistance R X  of a temperature sensitive platinum element.

Abstract: 1326559 Control of electric motors WINDMOLLER & HOLSCHER 21 Dec 1970 [30 Jan 1970] 60620/70 Heading H2J In an automatically controlled drive for driving an ejector band (not shown), which is arranged to receive the output of a tube forming apparatus (not shown) and serves to stack or otherwise deposit and then carry away lengths of tube for the manufacture of sacks or bags, a drive motor M A  (Fig. 1) for the band is energized via a control device St + L, by two voltages simultaneously (or successively, as Figs. 3 and 5, not shown) i.e. by a constant voltage from a D.C. voltage circuit P 1 , Q G1  and by a variable voltage proportional to the operating speed of the tube drawing machine derived by a circuit comprising a tacho generator T G1  and a potentiometer P 2 , whereby the band speed is matched to that of the tube forming machine. A desired initial speed for the ejector band is pre-set by adjustment of P 1 , and adjustment of P 2  determines the gradient of the relative speeds as illustrated in Fig. 2 wherein the tube forming machine speed is along the abscissa and that of the band along the ordinate. The instantaneous speed of the ejector band is sensed by a tacho generator T 1  which feeds a corresponding signal back to the central device. The desired instantaneous speed signal is that from the said constant and variable voltage circuits. In the alternative embodiment Fig. 3 (not shown) the machine speed and ejector band speed are compared in a comparator (G D ) which actuates a switch to apply the output of the variable voltage circuit to the control device instead of the constant voltage, if the tube drawing machine speed has reached that of the band. Alternatively, the switch may be actuated when the tacho-voltage proportional to the tube drawing machine speed, is greater or less than a predetermined value. In a further embodiment, Fig. 4 (not shown), the constant voltage and tacho voltage are applied via respective rectifiers to the controller whereby only the higher of the two voltages is effective.
