Abstract: 1306505 Laminates G POHL 22 Jan 1970 [25 Jan 1969 15 March 1969 10 June 1969 16 July 1969] 3167/70 Heading B5W [Also in Divisions B2 and D1] A material comprises a support layer which is gas, steam, moisture and fluid permeable and carries a high-frequency weldable medium in the form of areas of powdered synthetic resin, of which the particles are uniformly distributed in the areas and the areas form a regular pattern on the support. The support may be of polyurethane foam, woven and non-woven fabrics, bobbinets, knitted fabrics, needle punch pile fabrics, textile fabrics having adhered tufts, foam-bonded textile fabrics, cellulose, wadding, felt, netting, plaited fabrics, flock textile fabrics, paper, cardboard, leather or artificial leather. The powdered synthetic resin may be of polyamides or modified polyamides. The areas of powdered resin are provided on the support by the use of a structured roller having recesses corresponding to the desired distribution of the powder, the powder being fed from a hopper to the structured roller and the support is then applied to the roller under pressure. The powdered synthetic resin may be applied to both surfaces of the support. Covering layers may be joined by calendering on one or both surfaces of the support. The covering layers may be of textile fabric, e.g. woven cotton fabric, or foam sheet, and fillers of non-woven fabric may be provided between the covering layers and the support. In one embodiment, the support is provided on one surface with a filler layer of non-woven fabric, a foam layer and then a covering layer. The material may be welded with high-frequency electrodes so as to produce a quilted effect.

Title: Method and Arrangement Concerned with Remote Protection Devices on Power Transmission Lines.
IPC: H02H1/00
Filed: 1967-01-23
Abstract: 1,171,824. Signalling over power circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. 23 Jan., 1967 [21 Jan., 1966], No. 3394/67. Heading H4R. In a protective system for the remote control of circuit breakers over power lines by high frequency currents superimposed on the supply current, the receiver of the H.F. currents is protected against operation by disturbing voltages on the line network by circuits which respond to disturbance pulses exceeding a predetermined amplitude and having a rise time below a predetermined value to produce a blocking pulse of a predetermined duration which is used to inhibit the operation of the circuit breaker in response to the output of the receiver. Fig. 2 shows an arrangement of a circuit breaker 4 which is opened in response to a carrier frequency signal received over the line 1. The carrier frequency signal from line 1 is fed over capacitor 2 and line terminal 11 to a frequency selective receiver 7 to open the breaker 4 via a power amplifier 6 and relay unit 5. A protection channel 12 comprises, Fig. 3, a high pass filter 22 which blocks the carrier frequency and a monostable trigger 23 which is operated by disturbance pulses of above a predetermined amplitude and below a predetermined rise time. The trigger output feeds an integrator 24 and the voltage across this circuit controls a Schmitt trigger circuit 25, so that the Schmitt trigger is operated all the time the integrator voltage is above a predetermined value, and the trigger output operates a transistor relay 26 to apply blocking signals to the carrier frequency receiver output to prevent the disturbance signal operating the circuit breaker. The blocking pulse is arranged to block the receiver output before the disturbance pulse arrives at the output and to be maintained for a predetermined time after the last disturbance pulse.

Abstract: <PICT:0866149/III/1> <PICT:0866149/III/2> A moistening arrangement 21, Figs. 1 and 2, for moistening released strips extending in feed direction of copy sheets 43 moving towards a printing couple 1, 12 is pivoted at 22 and controlled by a cam 23 on the printing drum 1 through a roller 24, intermediate lever 25, and roller 26, so as to be swung into operative position during part of each revolution of the drum. The arrangement 21 comprises a plurality of side-by-side felt strips 28, each in a box 27 carrying a pin 32.  Each pin 32 is engaged by a slot in a rotatable key 33, which on depression moves the strip 28 to the left into operative position, an opening 39 in the box 27 coming underneath a spray opening 37.  At the same time the key 33 moves a slide 35, so that a spring-loaded pin 36 thereon releases the spray opening 37 and engages a recess 38 to lock the box 21 in operative position.  A lever 40 causes switching shafts 41, 42, and on counterclockwise movement the shaft 41 restores all the keys 33 and thus all the strips 28, while on clockwise movement the shaft 42 moves all the keys 33 to operative position.  In another form, a single strip 28 is used, and the pins 32 are mounted on a series of marking sheets.  A transfer roller may be interposed between the strips 28 and the copy sheets 43.

Abstract: 810,955. Measuring fluid flow. JONES, B. Feb. 6, 1956, No. 3586/56. Class 69 (1). [Also in Group XIX] The differential pressure set up between the throat and the downstream portion of a venturi section of a conduit (see Fig. 3) is transmitted by perforations 11 and bore 13, and bore 14 (respectively) to ports 58 and 64 in a housing 26 (see Fig. 5) and through limp isolating diaphragms 57, 56 to the inside and outside respectively of bellows 25 the movable end of which carries a two-part stem 33, 34. The stem has a disc 35 and cap 38 screwed on to its outer end, the disc being attached to the housing by springs 36; movement of the bellows against the action of these springs is transmitted to the housing exterior as a measure of fluid flow by a rotatable tube 52 having an arm 49 which engages a trunnion 48 on the part 34. Damage to the bellows is prevented by valve closure rings 42 and 43 which engage seats 40, 41 to close the bellows interior when the differential pressure becomes excessive in either direction. In an alternative form the isolating diaphragms are contained in a separate housing. Specifications 652,880 and 724,299, [both in Group XIX], are referred to.

Title: Improvements in or relating to indicating devices for use with internal combustion engines
IPC: G01L3/24
Filed: 1930-02-03
Abstract: 344,617. Indicating efficient performance of work. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Feb. 3, 1930, No. 3609. Convention date, June 15, 1929. [Class 106 (ii).] An internal-combustion engine is provided with an indicating device controlled by a governor in response to the speed so that indication is given of the load on the engine. In the application described the invention is applied to an electrically propelled vehicle having a generator driven by a six-cylinder engine. On the dashboard there are arranged a voltmeter u, a revolution counter t, an ammeter v, a controller s and indicator l. The indicator comprises a window behind which are adapted to appear indicators each of which has an armature engaged by a spring so that the indicator is normally below the window. A centrifugal governor driven from the engine is adapted to move a lever d about a pivot c. One end of the lever is connected to the fuel pump so that more fuel is supplied as the speed falls, the other end is fitted with an insulated contact moving over a contact k and contacts <0>/1, 5 .. 10. These are connected up in circuit with a battery h, regulating resistance i and an indicator l at the front and back of the vehicle. In the position of the lever d shown, the circuit is from the battery to contact k, contact <0>/1 lead x<1> to coil m and leads n, p, back to the battery h. The coil m raises the corresponding indicator <0>/1 corresponding to the engine running idly and no load. At various speeds and loads various indicators should show up. If one cylinder fails, the lever d moves lower and brings into view other indicators than that corresponding to the speed and load thus showing to the driver that the engine is not working satisfactorily. Tables of correct indicators for certain conditions are described in the Specification. Audible alarm devices may be fitted instead of or in addition to the visual indicators.
