Title: Means for producing mats of fibrous material
IPC: D04H3/004
Filed: 1960-11-10
Abstract: 907,257. Forming fibre mats. ALLMANNA SVENSKA ELEKTRISKA AB. Nov. 10, 1960 [Nov. 11, 1959], No. 38588/60. Class 120 (1). Apparatus for forming glass or other fibre mats by blowing strands through nozzles to lay them on a movable surface has screens of channel form located between the nozzles. The fibre strands may be fed by rollers 3 to nozzles 4 which may be horizontal, or point upwards or downwards, and that are supplied with compressed air to forward the strands in spirals or loops on to a wire gauze conveyer 6. In order to prevent disturbance in the flow path of the strands leaving the nozzles 4, screens 10 mounted for longitudinal adjustment between the nozzles are formed as connected side walls. Each screen 10 has an open side that may face downwardly, Fig. 3, or upwardly, or alternate screens may have their open sides oppositely located, Fig. 5, or the screens may form a continuous unit, Fig. 6. Alternatively, each screen may consist of separate parts, such as flat sheets mounted angularly to each other. The threads may consist of untwisted or twisted continuous glass fibre threads, spun staple glass fibre threads, or polyamide or polyethylene glycol terephthalate fibres. A binding agent may be added to the mat. Specification 887,575 is referred to.

Title: Improved arrangements for controlling the speed of vehicles
IPC: G05D13/00
Filed: 1929-12-17
Abstract: 345,331. Controlling speed of motor vehicles. BROWN, G. D., Dowery, Nantwich, and MATTHEWS, R. K., Moorsfield House, Audlem, both in Cheshire. Dec. 17, 1929, No, 38645. [Class 57.] In a means for controlling the maximum speed of a motor vehicle, a centrifugal governor operates to vary the connection between the accelerator and the engine throttle. The governor 4 is driven at a speed proportional to the vehicle and has attached to its moving sleeve a piston 14 provided with a needle valve 23 adapted to seat in the wall of cylinder 5 wherein two opposed pistons 19, 21 operate separated by a fluid link. The rod 18 is attached to the accelerator and the rod 20 to the throttle valve. Upon increase in speed the movement of the piston 14 decreases the fluid link in cylinder 5 thereby closing the throttle valve. In modifications the same effect is obtained by causing the governor to operate on right- and lefthand threads, or cams or the pivot of a lever.

Title: Corpuscular beam apparatus
IPC: H01J37/20
Filed: 1976-09-17
Abstract: 1518051 Automatic control SIEMENS AG 17 Sept 1976 [19 Sept 1975] 38704/76 Heading G3N A corpuscular beam apparatus, e.g. an electron or ion microscope, having an object mount 4 in the form of a goniometer is provided with a control unit (S) Fig. 3 (not shown) which, when the object mount rotates, automatically corrects its translatory co-ordinates x, y, z so that a specific object point retains its position relative to beam, A. The rotary motion of object mount 4 is performed in small steps so that the corresponding movement of the object point can be regarded as a straight line. As shown the object mount is a tilt/rotate goniometer. Setting up devices in the control unit (S) supply pulses to respective servo-systems. To prevent movement of the object 3 when it is desired to keep it still, each servosystem includes switching means to connect at such times an actual value signal to a set-point generator in the servosytem. In addition, to prevent the object point moving out of the field of view upon rapid rotation of the object, each servosystem has means to stop the control unit if a predetermined difference between the set point and actual values is exceeded. The site of the stepping angles may be dependent upon the magnification. The control unit (S) also has an electronic correcting system (K) Fig. 6 (not shown) which receives signals representing the actual values of the x, y and z co-ordinates, the tilt angle, and the increments in tilt angle, rotation angle and x-co-ordinate and - which, by means of approximate formulae, computes the necessary translatory co-ordinate displacements. The electronic correction system (K') for an object mount in the form of a double-tilt goniometer is depicted in Fig. 8 (not shown).

Abstract: 1,236,872. Electrochemical devices. SIEMENS A.G. 6 Aug., 1969 [6 Aug., 1968], No. 39446/69. Heading H1B. The potential of an electrode consisting of pulverous catalytic material in electrochemical devices, such as fuel cells or batteries, can be made substantially constant over the whole area by compressing the catalytic material hydrostatically or aerostatically in the device by cushions which can be filled with a gas or liquid, and which when there is one cell are disposed outside electrically conductive lead-out gauzes adjacent each electrode, and when there are two or more cells, are disposed at least outside the outermost gauzes, and which when fluidfilled press the gauzes against their adjacent electrodes, thus exerting substantially uniform pressure. A member in which electrolyte is contained is disposed between the electrodes and may comprise a porous supporting structure which is separated from the electrodes by liquid permeable, gas impermeable membranes e.g. asbestos, or the member may be an ion-exchange resin separated from each electrode by a gauze. Other gauzes e.g. a metal or plastics material, may be provided between each of the lead-out gauzes and the cushions adjacent thereto. Preferred devices are those which include means for circulating the fluid through the cushions, means for cooling circulating fluid and/or means for varying the pressure of the fluid in the cushions. As shown, a fuel cell comprises a supporting structure of a coarse-meshed nickel gauze 45, on both sides of which are situated asbestos diaphragms 46 and 47 for the electrolyte, on the outside of which are pulverous electrodes 48, 49 and current lead-outs 50, 51 of nickel gauze. Spacing members 52, 53 consist of metal gauzes and the two end plates 54, 55 are provided with pressure cushions 56 and 57. In a fuel cell described the anode consists of pulverous Raney Ni and the cathode of pulverous Raney Ag, the electrolyte is KOH and the reactants are hydrogen and oxygen.

Title: Signal transmitter

Filed: 1975-09-26
Abstract: 1528460 Compander systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Sept 1975 [1 Oct 1974] 39528/75 Heading H4R In a compander for a transmission system in which a pilot signal is added to the information system prior to compression at the transmitter and the pilot signal used to control expansion at the receiver, the information signal is applied to a double sideband suppressed carrier modulator before it is added to the pilot signal, and the pilot signal is formed by the carrier signal used in the modulation stage but at a different phase angle to that which the carrier would have if it were not suppressed. The modulated signal plus pilot is compressed in a conventional manner and at the receiver the expansion can be accomplished conventionally as in Fig. 2 (not shown) or preferably the received signal can be expanded by applying the composite signal to a filter which converts the double sideband signal to a frequency modulated signal which, after limiting and frequency demodulating provides a signal with the dynamic range restored to the original value. As described the transmitter Fig. 1, has a band limiting filter 2 and amplitude limiter 3 from which the level control signal is derived by rectifier filter 7 and comparator 10 with reference 11. The control signal controls the impedance of a diode connected across the signal path in the control circuit 26, Fig. 3, to which is applied the information signal from limiter 3 after it has been double sideband suppressed carrier modulated in modulator 23 and combined with the carrier signal from source 12 after the carrier has been phase shifted 90 degrees in circuit 27 so that the pilot signal is in quadrature with the carrier supplied to modulator 23, the pilot signal being at a level equal to the level at which compression commences to become effective. At the receiver the amplified received signal is applied to a circuit 55 tuned to the pilot, or carrier, frequency and to the limiter 56. The filter has a response which falls at 6 dB/octave above 300 Hz spacing from the carrier which converts the signal from double sideband amplitude modulation to frequency modulation, while the limiter modifies the frequency spectrum such that when demodulated in discriminator 57 the original amplitude range is restored. A double sideband suppressed carrier modulator and compressor circuit is described with respect to Fig. 4 (not shown).
