Title: Improvements in or relating to electrostatic precipitator installations
IPC: B03C3/017
Filed: 1959-02-10
Abstract: 840,707. Electrostatic precipitation. METALLGESELLSCHAFT A. G. Feb. 10, 1959 [April 24, 1958], No. 4681/59. Class 39(1). [Also in Group XII] An electrostatic precipitator, e.g. comprising three groups of electrodes for cleaning gases emerging from blast furnaces, is preceded by a Venturi cleaner and scrubber Ve which is itself preceded by a preliminary ionizer J, and an axially arranged pressurised water nozzle De acts as an injector into the Venturi cleaner in order to produce a gas pressure at the outlet of the precipitator which exceeds that at the crude gas inlet. The cleaned gas is then utilized for ventilating the electrical insulators associated with the electrostatic precipitator and the preliminary ionizer. The gas stream emerging from the Venturi cleaner impinges on plates St and is deflected through 180 degrees to pass through the precipitator. Several liquidflushed Venturi after-cleaners and coolers may act on the gas stream after it leaves the precipitator, the gas stream being again deflected through 180 degrees to pass through these cleaners. These Venturis are situated on either side of the pre-cleaning Venturi Ve. The complete water-circulating system is described. Water is also provided for spray devices Ed and flushing devices Eb in the precipitator and for an annular chamber R surrounding the Venturi inlet which injects water to clean the Venturi throat. Clean water used in the Venturi aftercleaners may be circulated to the pre-cleaning. Venturi Ve, non-return valves are provided in the water circuit to ensure that pressurised water is still supplied to the Venturi Ve in the event of failure of the main water pressurising pump. Clean gas may also be supplied to the annular chamber R if desired.

Filed: 1946-02-18
Abstract: 608,207. Grinding skate blades. FORRESTER, P. M. Feb. 18, 1946, No. 5078. [Class 60] A method of grinding or regrinding the blades of ice skates consists in using one blade of a pair of blades as a profile-template and grinding or re-grinding the second blade of the same pair of blades in accordance with the profiletemplate formed by the other blade. Skate blades 16, 18 of a pair of skates are clamped on either side of a support 88 along the centre of which is slidable a base-plate 46 carrying an upright 44 and an electric motor 132. A frame 32 pivoted about a horizontal axis in the upright 44 carries at its free end a grinding- wheel 12 driven by the motor 132 and adapted to grind the blade 16, and an adjustable follower 14 adapted to engage the other blade 18. Thus, as the base-plate 46 is traversed along the bed of the support 88, the blade 18 acts as a profiletemplate to which shape the blade 16 is ground. The blades may then be substituted for one another and the blade 18 ground, using the blade 16 as the template. An adjustable stop 66 is fitted on the frame 32 to prevent the grinding-wheel from dropping when it reaches the end of the skate blade. As an alternative, the grinding-wheel and follower means may remain stationary and the blades be traversed thereunder.

Filed: 1920-02-25
Abstract: 161,787. Fenby, E. B. Feb. 25, 1920. Folding edges of sheet material.-A folder for use in machines for making four-fold linen collars &c. consists of thin metal strips arranged side by side so that by relative sliding movements their operative ends can be caused to assume any desired configuration. Groups of thin metal strips a - - d, Fig. 4, forming the folders are adjustably clamped in slidable holders. Solid folders e are provided for forming the double corner folds or lock corners. The folders are normally held in their outer positions by springs and are moved inwardly by compressed air cylinders, the folders e having weaker springs so that they are the first to be moved by their cylinders. The groups d of strips forming the corner folders are interspaced by shorter strips, so that as these folders move inwardly, they remain in contact with the adjacent folders. In use, strips 3, Fig. 6, of material to be folded are laid in recesses formed in the inner ends of the folders and are pressed against a spring-supported electrically-heated table 2 by a hinged plate w. The folders then move inwardly and turn the edges of the material over the plate. Compressed air is then admitted to a diaphragm 7, which expands and presses the folded material between the folders and the heated table. Upon release of the pressure in the cylinders and the diaphragm, the folders move outwardly under the influence of their springs, and the plate w can be raised for the removal of the folded article. The control of the compressed air to the cylinders and the diaphragm is effected by a valve-device which is put into operation when the plate is lowered by a projection on an arm carrying the plate.

Mechanism associated with a pedal or leverapplying means for equalizing the forces transmitted to two brakes or sets of brakes comprises two axially-spaced lugs to which the pedal or lever is to be coupled for transmitting angular movement thereto, and a balance bar rockably mounted on the pedal or lever about an axis at right angles to the axis of the angular movement and arranged with its opposite ends engaged between spaced abutments on each of the lugs. As shown, pedal 10 has a boss 11 mounted for free rotation on a shaft 12 to which are secured a first lug 14 and an arm 22 connected by a link or cable 23 to one brake or set of brakes. A second lug 17 freely rotatable on the shaft between the boss 11 and a support 20 in which the shaft is journalled has an integral arm 18 connected by a link or cable 19 to a second brake or set of brakes. Force is transmitted to the lugs by a bar 25 pivoted for rocking on a pin 26 engaged in a recess in the boss 11 and a further recess in a cover-plate 27 bolted to the boss, the bar having part-spherical surfaces 31 at its ends which engage the inner surfaces of a pair of abutments 29 on each of the lugs 14, 17. The bar 25 rocks to a position in which equal forces are transmitted to the two lugs. However, relative angular movement between the lugs and the pedal is limited by the engagement of abutments on the adjacent faces of the lug bodies with the ends of recesses 33 in the boss 11 which are larger than these abutments. Instead of a pedal 10 a hand lever may be used, the two brakes operated thereby being applied respectively through a rigid link and through a cable.

Title: Improvements in or relating to frequency dividers
IPC: H03B19/00
Filed: 1953-03-02
Abstract: 726,984. Pulse frequency dividing circuits; radar. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 2, 1953 [March 21, 1952], No. 5758/53. Classes 40 (6) and 40 (7). In a circuit for selecting one of a train of highfrequency pulses at a lower recurrence rate, a pulse from an adjustable oscillator is used to gate the first pulse train to select the desired pulse. The high-frequency pulses may be used for the production of calibration pulses on the C.R.T. screen of a radar set, the selected pulse being used to trigger the time base. The circuit will operate when there is no integral relationship between the recurrence frequency of the two pulse trains. Sine waves from crystal controlled oscillator 1, Fig. 1, are fed to squarer 2 and shaping circuit 3. Pulses from a blocking oscillator or multi-vibrator 4 are shortened in circuit 6 and applied to a circuit 7, Fig. 3, wave 11, to feed a waveform 12 through a discriminating circuit 8 to a flip-flop 18 and amplifier 19. In the absence of a pulse from the oscillator 4, valve 7 operates normally so that the pulses 10 appear inverted at the anode, wave 12. When a positive-going pulse from oscillator 4 drives the screen and suppressor grid positive, valve 7 operates as a dynatron to generate a positivegoing pulse. The pulses 11 are arranged to have a duration slightly in excess of the spacing of pulses 10 so that two adjacent positive pulses may occur in wave 12 (Fig. 4, not shown) but only the first is effective to trigger the flip-flop 18 to generate a single output pulse. The stages 6, 18 may be replaced by valves with inductive loads.
