Title: Improved method and apparatus for determining the permeability of a material
IPC: G01N15/08
Filed: 1966-08-11
Abstract: 1,145,542. Determining permeability. S. SUNNER and K. ROSENGREN. Aug.11, 1966 [Aug.13, 1965], No. 35994/66. Headings G1N and G1S. Apparatus for determining the permeability of a material 4 comprises a test detector chamber 7 and a reference detector chamber 7' which are maintained at constant and equal pressures, the test detector chamber 7 being divided from the test fluid chamber 6 by the test foil 4 and the reference detector chamber 7' by the reference foil 5, and the measurement result being obtained in the form of a change of a measured differential value depending on the change of fluid composition in the test detector chamber caused by diffusion of fluid through the test foil. The detector chambers 7, 7' and the fluid chamber 6 are initially scavenged with a reference gas until a stable condition is reached. The fluid chamber 6 is then scavenged with the test fluid to bring about diffusion of the test fluid through the test foil into the test detector chamber and diffusion of the reference gas in the opposite direction. The reference gas is removed from the fluid chamber by the scavenging test fluid. Pressure variations are prevented by putting at least the test detector chamber into communication with a large gas volume by a narrow connection 21. Detectors in the form of thermistors 9, 9' are provided in the detector chambers and form part of a bridge circuit so that as the fluid composition varies the resistance of the thermistors varies to give a measure of the amount of test fluid which has permeated the test foil. The foil 5 is made of a material which is impermeable to the test fluid. The apparatus is calibrated by passing a known volume of gas into the test detector chamber by means of a device 23. The entire apparatus is housed in a thermostatic container. In a second embodiment the chamber 6 is divided into two separate compartments, one containing the test fluid and the other the reference gas and the reference foil 5 is made of the same material as the test foil.

Title: Double apron drafting device
IPC: D01H13/18
Filed: 1969-07-17
Abstract: 1281714 Drafting; lap stop motion MASCHINENFABRIK RIETER AG 17 July 1969 [26 July 1968] 36026/69 Heading DID In a double apron drafting arrangement comprising a cage 5 which guides the front ends of the aprons close to the nip of the delivery rollers 10, 11 and is pivoted about bottom apron roller 7, the cage is normally prevented from tilting by a pressure saddle 20 engaging the axle of the top apron roller 6 but when a lap 26 is built up on the lower delivery roller 11 the nose of apron 9 is lifted so causing the cage to rotate to the position shown in Fig. 2. The roving between rollers 6, 7 and rollers 10, 11 is broken by the rotation of the cage and because pressure is released from roller 6 the roving is no longer forwarded by the aprons and accumulates beneath the rollers until the arrangement is pieced up. Saddle 20 is mounted on a member 17 pivoted on the weighting arm 18 at 19 and member 17 also rotates when a lap is formed. A spring member 25 mounted on member 17 engages the axle 22 of roller 6 as it is pivoted away from its working position so that roller 6 is not pushed into contact with roller 3. In a further form cage 5 is constituted by separate upper and lower parts which are detachably connected.

Abstract: 338,014. Allgemeine Elektricitõts- Ges. Nov. 24, 1928, [Convention date']. Coils and conductors; armatures, cooling; field magnets, dampers on cores of.-The shrunk-on rings or bindings securing the rotor end windings of dynamo electric machines are subdivided so that each part covers one group of windings and spaces are left between the parts of the bindings to permit independent expansion of the several winding parts and to allow cooling air to pass through the end windings. In the example shown in Fig. 1, there are seven concentric end windings 3. The six outer windings are held in pairs by U-shaped clamps 7 secured by a binding 6. The slot wedges 4 rest on the inner end winding 3 and on a filling piece 5 and are connected together mechanically and electrically by a binding 6<1> so as to constitute a damping cage. Air circulated by a fan 11 enters between the end connections from an axial groove 12. The arrangement may be such that air passes over both sides of the end windings which my be arranged in groups of three or more. In a modification, Fig. 3, six concentric windings are employed, and the clamps 7, which are double T-shaped, are laid between the turns of the bindings. In each case metallic inserts 9 and insulating layers 8 are laid between the clamps and the windings.

Title: Facsimile scanning mechanism
Inventor: BELL JOHN
IPC: H04N1/16
Filed: 1956-11-29
Abstract: 815,553. Facsimile recording mechanisms. MUIRHEAD & CO. Ltd. Nov. 29, 1957 [Nov. 29, 1956], No. 36495/56. Class 40 (3). A scanning mechanism for a facsimile recorder, particularly of the kind utilizing electrolytic recording, comprises means for traversing individual ones of a plurality of conductive balls across the recording medium to produce a line scan, means being provided for returning each ball to the starting point of the scan in preparation for the scanning of succeeding lines. As shown in Fig. 1, the recorder comprises a rotatable drum 11 provided with a helical groove 12 into the left-hand end entrant circular portion 17 (Fig. 4) of which and between two guideplates 13 (Fig. 2) mounted above the drum the balls are forced via a spring-loaded stopmechanism 26 so that, as the drum rotates and the balls enter the groove 12, each ball, e.g. 14<SP>1</SP>, moves in a linear path to effect a line scanning action, the record sheet 15 (Fig. 2) being marked by electrolytic action in accordance with picture signals applied between the ball 14 and a fixed electrode 16 which extends over the full length of the guide-plates 13. At the end of the scan (i.e. at the right-hand end of drum 11 (Fig. 1) the balls are forced into a groove 25 and, via a further spring-loaded stop mechanism 26a, into a second groove 23 which communicates with the left-hand end of the drum via a tube 29 containing a continuous line of balls. When a fresh ball is to be supplied to the entrant circular portion 17 (Fig. 4) a plunger 21 driven by a crank 19 and rotatable shaft 20 operates to press the line of balls along tube 29 by a distance sufficient to force one ball past the stopmechanism 26, such action, in the case of the two-turn helix shown in Fig. 1, being arranged by means of suitable gearing between shaft 20 and the drum rotating mechanism to occur shortly after the operative ball 14<SP>1</SP> has passed the middle point of the scan. When the latter ball reaches the end of the scan the fresh ball already in the entrant portion 17 is " pickedup " by the groove 12 and the next scanning line commences. By driving shaft 20 at the same speed as the drum two line scans, side-byside, may be produced and by increasing the number of turns of the groove 12 a larger number of side-by-side line scans may be produced, the electrode 16 being divided into a like number of insulated portions.

Abstract: 809,386. High-frequency suppressor circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 3, 1956 [Dec. 6, 1955], No. 36872/56. Class 40 (8). In an apparatus in which high-frequency oscillations from a shielded generator are transferred to a load via a pair of parallel conductors, e.g. a high-frequency furnace, a parallel resonance circuit is formed by a capacitor across part of at least one of the conductors which has an inductance; said circuit together with the impedance between the shield and the conductor adjacent thereto forms a suppressor system for the higher harmonics of the generator. Generator 1 comprises two coupled values 15, 16 in a housing 2 and the oscillations are transferred to the load 5 via variable capacitors 17, 18 and said conductors 3, 4. The capacitor 6 is connected across the part 7, 8 of conductor 3 and may have a low trimmer inductance 11 of high internal resistance in series with it which may have a movable core 12 of ferrite having high losses at the frequency used. The impedance between the conductor 3 and the housing 2 may be the self-capacity between those parts, or provided by a separate capacitor 9. Both conductors 3, 4 may have an associated suppressor system, and an inductance 10 may be placed in series with the capacitor such as 9 to form a series resonance circuit.
