Abstract: 706,136. Roller clearers. CASABLANCAS HIGH DRAFT CO., Ltd. Aug. 7, 1952 [Sept. 26, 1951], No. 22507/51. Class 120(2) In a spinning or other preparatory machine wherein consecutive pairs of top rollers are carried by common neck portions in pivoted support arms, so that between consecutive pair of support arms there are two lines of drafting rollers, the top roller clearers are carried in frames which are disposed between adjacent support arms and are pivoted at their rear ends in a readily detachable manner. The clearers 20, 22, Fig. 1, each co-operate with rollers in both lines. The support arms 1 are pivoted at 2 in brackets 3 mounted upon the bar 4 at the rear of the drafting rollers. Slots 12 are provided upon the clearer frame 10, Fig. 2, to pivot upon projections 11 on facing sides of the brackets 3, Fig. 1. In the operative position the frame 10 rests by shoulders 13a engaging projections 14 on the brackets 3. The frame may be raised to an inoperative position (broken lines), Fig. 1, in which recesses 13b engage the projections 14. The clearer pivots rest in guide slots 17 and 18 which are shaped to prevent the clearers falling out in the raised position. To detach the frame 10 and clearers from the machine the frame is moved to the inoperative position, is then raised, the slot 12 being of sufficient depth to permit this, pivoted slightly further backwards and then lowered to detach the slots 12 from the pivots 11. The support arms 1 are provided with projections 22a which extend: under the frames 10 so that the frames will also be raised if the support arms are pivoted upwardly. In a modification, Fig. 3, the frame comprises side arms 23 of' spring material connected by a cross-stay 24, the arms 23 being apertured at 27 to fit pivot pegs 28 on the brackets 3. To remove the frame the side-members 23 are squeezed inwardly to release the pivots 27. The side-members are shaped, at 29, to provide spring supports for button-headed rivets 30 which snap into depressions 31 in the brackets 3 to hold the frame in the inoperative position. In further modifications (not shown) the slots 17 may be provided in guides hinged to the frame to prevent the rollers 20 falling out in the raised position, or a sliding arm may be provided to extend over the clearer pivots as a latch. A frame is provided. at each end of the machine in which the clearers embrace the single line of rollers only. In some cases two frames of single roller, width may be positioned side by side between adjacent support arms.

Title: Casing for the fuel elements of a water-cooled nuclear reactor
IPC: G21C1/08
Filed: 1976-06-02
Abstract: 1511772 Fuel elements COMMISSARIAT A L'ENERGY ATOMIQUE 2 June 1976 [4 June 1975] 22791/76 Heading G6C A casing for the fuel elements of a watercooled nuclear reactor comprises a number of identical compartments A, B, C, D, &c. within each of which are housed one or more fuel plate assemblies which are not secured to the compartments. The casing walls 6 are each made up of two thin vertical metal sheets, e.g. 21 and 22, 23 and 24, 25 and 26, 27 and 28, between which are welded tubes, e.g. 29 to 33, 34 and 35, 36 and 37. The sheets and the tubes are pierced by orifices 38 along their lines of contact and along the compartment walls located at right angles to the fuel plates 80. The tubes e.g. 29, may serve to accommodate neutron-absorbing rods (not shown) of, e.g. hafnium which together form a cruciform control rod (40) or a T-section control rod (41), (Figs. 2 and 3, not shown). As shown in Fig. 5, the tubes, e.g. 29, may be supplied with emergency coolant water by means of a duct 44 within the upper reactor grid, as indicated by the arrows F, the water discharging into adjacent compartments through the orifices 38, and with neutron poisoning liquid (water containing boron) by means of a duct 46 beneath the lower reactor grid 14, the poisoning liquid also discharging through the orifices 38. A diaphragm 49 having a reduced passage is provided within each tube 29 in order to prevent the mechanical shock which could result, at the moment of simultaneous starting of the two emergency circuits, from the pressure difference between the poisoning circuit (which is at high pressure) and the cooling circuit (which is at low pressure). In an alternative construction (Fig. 6, not shown), the two circuits are connected to different tubes 29, thus avoiding the need for diaphragms 49. In a second embodiment, Fig. 10, the casing is composed of two families A and B of walls defining compartments C, certain of the walls B, e.g. that between compartments 70, 71, comprising thin metal sheets 63, 64 welded at intervals to solid metallic stiffening bars 65 to 69 of rectangular cross-section to define free spaces 72 to 75 for the injection of emergency coolant water and/or neutron poisoning liquid by means of orifices 90 to 93 pierced at different levels in the sheets 63, 64. As shown in the case of the adjacent wall, some of the free spaces may house nuetron-absorber strips 81, 82 connected by a member 83 to form a reactor control rod.

Title: Method of applying a synthetic resin binder to a non-woven fibrous material
IPC: D04H1/66
Filed: 1971-08-20
Abstract: 1358569 Print bonded fabrics; testing fabrics JOHNSON & JOHNSON 20 Aug 1971 [21 Aug 1970] 22908/72 Divided out of 1358568 Headings D1R D1S and D2B A fibrous web is printed in an intermittent pattern of spaced areas with a stable, alkaline colloidal aqueous dispersion comprising a synthetic resin, a hydroxy containing co-ordinating ligand, e.g. carboxyl, in said resin or in a surfactant present in the dispersion and a metal complex coordination compound; the dispersion being acidified immediately after printing or the fabric heated to expel volatile alkali such as ammonia, whereby metal cations are released from coordination to coagulate the dispersion before it can migrate far. The web may be of orientated carded fibres, or the fibres of such a web may be rearranged by fluid jets; alternatively air laid or wet laid webs may be used. 1¢ inch, 1¢ denier rayon fibres, bleached cotton and 2¢ denier water insoluble polyvinyl alcohol fibres are exemplified, wool, nylon 6, 66 and 610, polyester, acrylic, modacrylic, polyethylene polypropylene and cellulose ester fibres are listed. 1% to 8% acrylic, methacrylic or itaconic acid, polymerised with butadiene/styrene, ethylene/vinyl acetate or with an acrylic monomer are exemplified as binders; polyvinyl acetates, polyolefins, synthetic rubbers, polyurethanes, polyamides and polyesters are mentioned. The aqueous dispersion comprises 0.01 to 60% by weight of resin and, based on the weight of resin, 0.1% to 2% of a (preferably anionic surfactant) and 0.1% to 3% of a zinc tetramine sulphate or other specified metal complex coordination compound. It is applied with a roll engraved with wavy lines to a web wet with aqueous acetic acid. Binder migration is thus reduced to 200% or less, giving bonded areas having a substantially uniform concentration of binder of 50% to 120% by weight based on the weight of the fibres in the bonded areas. The binder may extend through all or part of the web thickness. In order to measure the binder distribution the print bonded fabric is immersed in a boiling solution of Celliton Fast Violet, which renders the cellulosic fibres white and the binder opaque. The dried sample is mounted on a white surface under a ground glass camera to yield as 20 fold enlarged image. The image is scanned by an optical densometer which is set at zero at a binder-free area. Measurements of reflected light are made very 2mm of the enlarged image. The optical density increases from zero to substantially its maximum value (0.6 to 1.0) in moving less than 1mm from an unbonded to a bonded area.

Title: Improvements in or relating to electronic valve apparatus suitable for use in counting electrical impulses
IPC: H03K23/82
Filed: 1944-11-17
Abstract: 584,704. Pulse counting circuits. FLOWERS, T. H. Nov. 17, 1944, No. 22912. [Class 40 (v)] An electronic counter comprises a ring of valves of the multigrid type in which a direct current derived from the circuit of each valve is applied to one grid of all the other valves and a voltage pulse is applied to another grid of one of the valves so that it attains a 'stable condition of electron flow different from that of the other valve, the output pulses produced being a sub-multiple of the input pulses. The Figure shows a ring of valves 1, 2, 3 in which, for example, valve 1 is non-conducting and the others conducting. A positive pulse applied to valve 4 causes a positive pulse to be applied through condensers 10, 20, 30 to the control .grids of each valve. This has .no effect on valves 2 and 3 but causes valve 1 to conduct. The drop of anode voltage produces a negative pulse which is applied through condenser 26 and resistance 27 to the suppressor grid of valve 2, thus cutting off the anode current of valve 2, the cathode current being diverted to the screen grid, resistor 29 limiting the screen grid current. The rise of anode potential of valve 2 is applied to the grid of valve 1 through resistor 12 to maintain it conducting, the condenser 26 being chosen so that the negative suppressor grid voltage remains effective until the D.C. voltage applied to the grid of valve 2 through resistor 23 is reduced to a steady value to maintain the valve non-conducting. Positive pulses produced at the anode of valve 1 every time it becomes non-conductive are applied through valve 5 to output lead L2. The pulse applied to condenser 30 drives the plate nearerthe grid of valve 3 positive and then negative with respect to the steady state condition and in order to prevent fluctuations in anode potential the common connection of resistors 32, 33 and 35 is given a potential higher than that at which grid current commences to flow.

Filed: 1926-09-17
Abstract: 258,614. Western Electric Co., Inc., (Assignees of Curtis, A. M.). Sept. 17, 1925. [Convention date]. Transmitting systems; restoring or modifying imperfect. signals; eliminating effects of disturbing currents.-In a submarine cable system the signals are shaped at the transmitting station by the provision of a connection to ground. from a point between the cable and the sending condenser, through a large condenser in series with an impedance of a valve which is small in relation to that of the cable. The arrangement minimizes earth current effects during the change-over from transmission to reception. Additional signal-shaping devices are provided in connection with the receiving apparatus. Fig. 1 shows a transmitter T and a receiver R of which one or other is connected to the cable according to the position of a switch 8. The sending condenser 19 is shunted by a resistance 20 and the grounded shaping impedance is a large condenser 1 in series with a low resistance 21. Fig. 10 shows a modified transmitting arrangement, the shaping impedance comprising a large condenser 90 and an inductance 91 with a shunt resistance 93 and a series resistance 92. The receiving arrangements include a recording instrument connected to the cable through an amplifying network similar to that described in Specification 248,823, a shield transformer 25, Fig. 1, and a shaping network. The latter comprises shaping devices N<1>, N<2>, N<3> in series with, and a shaping device N<4> partly in shunt with the transformer primary. The device N<1> is a variable condenser shunted by a variable resistance and is used to control the amplitude and phase of the lower-frequency components of the signal currents. The device N<2> is an antiresonant network comprising a variable conderser, an inductance, and a variable resistance in parallel, and is tuned to reduce the amplitude of frequency components below the signalling frequency. The device N<3> is a variable condenser shunted by a variable inductance, and is tuned to eliminate interfering frequencies. It is short-circuited, when not required, by a switch 38. The device N<4> is an adjustable autotransformer 30 connected as shown with variable resistances 28. 29. Specifications 240,034. 248,822, and 218,261 are also referred, to.
