Title: Improvements in and relating to methods and means for producing material or applyinga layer of material with a predetermined thickness
IPC: B29D30/38
Filed: 1954-03-30
Abstract: 788,061. Automatic linear dimension control systems. GENERAL ELECTRIC CO. March 30, 1954 [March 31, 1953], No. 9299/54. Class 38 (4). [Also in Group XXXVIII] In a method of producing a textile material or a finishing material applied thereto of predetermined thickness, a thickness varying operation is controlled by a signal derived through a magnetic recording device from a primary signal produced by a thickness sensing means. A signal derived from the primary signal is recorded on an endless tape driven at a speed proportional to the speed of the textile material, via a recorder head, the secondary signal being obtained from the signal picked up by a playback head spaced from the recorder head. In one embodiment (Fig. 5) for maintaining constant the thickness of a finish applied to rugs a # or X-ray thickness gauge 101 in advance of the treating roller 115 and a second thickness gauge 114 beyond the roller are used, the function of the magnetic recording being to allow comparison of the outputs of the two gauges corresponding to the same element of rug. This is done by recording the output of gauge 101 and playing it back at the time when the rug element to which it corresponds is at the second gauge. The gauge outputs are thus compared to give a voltage proportional to finish thickness which is used to control application of the finish. The D.C. output of gauge 101 is chopped and filtered at 103, 104 to give an amplitude-modulated wave which is used to produce a .frequencymodulated wave in 105 which is recorded on magnetic drum 107. The frequency modulated signal picked up by playback head 109 is converted at 112 to an amplitude-modulated signal which is rectified and filtered to a direct voltage which is compared with the output of gauge 114 to give the control voltage. Other non- retroactive control systems are described in Group XXXVIII.

Abstract: 1412923 Controlling converter steelmaking CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 1 March 1974 [1 March 1973] 9347/74 ] Heading C7D In a process in which oxidizing gas is blown into a converter and solid materials added, with the exhaust gases being collected in a hood, the following quantities are monitored; rate of supply of oxidizing gas, rate at which CO 2  leaves the converter, CO content of the exhaust gases, and decarburization rate of the metal bath. There are then calculated (a) the factor XF given by the expression where [CO]c and [CO 2  ] c  are the respective contents of the exhaust gases, and, from [CO 2 ] c , D(CO 2 ), (the rate at which C02 leaves the converter), the decarburization rate, and XF, (b) the parameters (i) rate of combination of oxygen with carbon from the bath, (ii) rate of oxygen take-up by slag and (iii) rate of combustion of CO in the converter. These three parameters are compared with predetermined values, which may vary during the course of a heat, and operating conditions adjusted to minimise deviations. The quantity D(CO 2 ) may be obtained by measuring the intensity of sound emitted by the converter, and [CO]  c  by measuring the intensity of light emitted, the values possibly being corrected intermittently by gas analysis. Modified methods of operating the invention to allow for the pressure of hydrogen (from dissociation of water) and nitrogen from ingress of air into the hood) in the exhaust gases are described.

Title: Continuity testing of electrical networks
IPC: G01R31/02
Filed: 1974-03-01
Abstract: 1465365 Continuity testing BOUSSOIS SA 1 March 1974 [13 March 1973] 9475/74 Heading G1 [Also in Division H2]  The continuity of a conductor deposited on a glass substrate, for example for heating a car windscreen, is tested by applying a potential across it, by sensing the potential a known distance along the conductor and comparing the sensed potential with its expected value. As described a rectified 22, Fig. 1 potential is applied across the parallelconnected heating element 2a of a windscreen 1, and a probe 13, connected via light-emitting diodes 12 to an appropriate tap 9 of the supply, is brought into contact with one of the heating elements at an appropriate distance along the element, so that if no fault exists neither diode lights, but if a fault exists in one half only of the element one of the diodes lights. In the preferred embodiment one probe 13 is provided, shown dotted in Fig. 1, for each heating element, and the probes are resiliently mounted in a jig, Figs. 2 and 3, (not shown), in which the windscreen is placed for testing, and the preferred test sequence is as follows:- (a) Before a windscreen is positioned in the test rig switches 14 are closed, thereby applying an auxiliary supply 23 across the light-emitting diodes 12, all of which should therefore light. (b) If all the diodes 12 are functioning properly, switches 14 are opened, the windscreen is positioned, and a switch 8 is closed. Any diode that then lights indicates that the associated conductor has a single fault in one of its two portions. (c) In the above test both for those conductors that are not faulty, and for those which have a fault in each of their two portions, neither of the associated pair of diodes lights, however, by opening switch 8 one diode of each pair associated with a non-faulty conductor will light, and thus diode pairs that remain unlit will correspond to conductors with two or more faults.

Abstract: 648,719. Washing and drying machines. BRITISH THOMSON-HOUSTON CO., Ltd. April 5, 1948, No. 9500. Convention date, April 5, 1947. [Class 138 (ii)] A clothes-washing machine comprises a unitary valve and pipe structure 31, Fig. 6, attached to the outside of a tub 3 for supplying water thereto and having discharge pipes 41, 42, one pipe (41) discharging directly to the tub and another (42) discharging through an inlet opening 26 in a soap box 21 provided with an outlet 25 at one end and attached to the underside of a cover 7 for the tub. The cover has an opening 20 through which soap powder may be placed in the soap box and an opening 17 through which clothes may be placed in a basket 48 in the tub, and a hinged lid 18 is provided for the openings. Soap is held away from the opening 26 by means of a shield 27 provided with a central opening 29 over which is a cover tongue 30. Water issuing from pipe 42 strikes the tongue 30 and is discharged in all directions, thus assisting in washing the soap powder from the soap box. Pipes 41 and 42 are supplied with warm and hot water respectively by two valves controlled by electromagnets 34 and 35. The valve casing 31 is attached to the outside of the tub 3 by means of a bracket 43. In a modification, Fig. 11, water supply pipes 60 and 61 are arranged to discharge to the tub 3 and soap box 69 across air gaps 63, 68 respectively and the arrangement is such as to prevent water being drawn or syphoned back into the water supply line when the water level rises in the machine. A nozzle 62 on pipe 60 discharges across gap 63 to a vertical conduit 64 formed by a wall 65 attached to the outside of the tub and communicating with the inside of the tub through a passage 66. A baffle 78 directs the incoming water across the bottom of basket 48 to break down suds which may have accumulated there. A nozzle 67 on pipe 61 discharges to the soap box through an opening 72 across which is positioned a shield 73 with an opening 74 and cover tongue 75. The tongue 75 is arranged at an angle to the plane of shield 73 so that the end towards discharge opening 76 of the soap box is spaced further from shield 73 than the other end, and most of the water is directed towards this opening. A curved lip 71 on the soap box is arranged lower than a curved lip 70 on the tub so as to prevent leakage of water through the space between the adjacent ends of the lips when the basket 48 is rotated for centrifugal drying of the clothes. Specification 625,324 is referred to.

Abstract: 559,305. Vehicle brakes. BENDIX AVIATION CORPORATION. July 9, 1942, No. 9570. Convention date, Oct. 13, 1941. [Class 79 (v)] [Also in Group XXXIV] In a vehicle brake system the force applied by the applying means of the brakes of the front wheels to the friction element or elements thereof is greater or less than the force applied to the friction element or elements of the rear wheel brakes according to the direction of travel in order that the braking action may correspond to the unequal distribution of the weight as between the front and rear wheels due to deceleration both in forward and rearward travel or due to the car being on a gradient. A hydraulic system is shown in which the brakes are of the kind comprising each a pair of shoes that anchor at one end or--the other-according to the direction of rotation of the drums. The application cylinders each have pistons 17a, 17b of different area and the disposition of the cylinders is such that when the brakes are applied during forward travel the shoes of the forward brakes A anchor on the smaller end of the cylinders and these shoes of the rear brakes B anchor on the larger ends of the cylinders. The larger and the smaller pistons are thus respectively effective on the front and rear brake.shoes and the braking action on the front wheels is thus greater than on the rear wheels. During rearward travel the smaller pistons are effective in the front brakes and the larger piston on the rear brakes and the braking action in the two pairs of wheels differs correspondingly. The Specification as open to inspection under Sect. 91 states also that this brake system provides for the redistribution of the weight on the wheels effected when the car is on a gradient. This subjectmatter does not appear in the Specification as accepted
