Abstract: Abstract of the Disclosure A methanation reaction of a gas containing hydrogen, carbon monoxide and carbon dioxide which is exothermic and takes place in a bed of solid catalyst particles in a reaction vessel through which the reaction gas flows is substantially improved by the use of an apparatus in which an upstream section and a downstream section, both containing particles of the same catalyst, are provided, the sections having different cross-sectional dimen-sions and appropriate lengths.  The reaction vessel is cooled by pressurized water confined by an external pressure container.  The ratio of the hydraulic diameter of the first section to the equivalent diameter of the catalyst particles therein is less than the corresponding ratio for the second section; and the length of the first section is such that the reaction gas, after having reached a maximum temperature, is cooled down, before the gas passes into the second section, to a temperature low enough for the temperature in the second section to remain below the maximum permissible temperature. The length of the second section needs to be only enough to establish thermodynamic equilibirum at a temperature corresponding to the desired product gas quality, preferably between the range between 311° and 370°C.  For reduction of the hydraulic diameter in a tube of given dimensions, inert particles or confining bodies can be put in the tube along with the catalyst particles.

Abstract: Abstract of the  Disclosure A flat frequency response compansion noise reduction system employs both input signal and control signal preemphasis and deemphasis in its encoder and decoder networks respectively. The linear range of the frequency response curve of the input signal deemphasis is selected to approximate the frequency range within the audio spectrum at which the human ear is most sensitive, typically having a high frequency end of 3.617 kHz. The frequency response curve of the input signal preemphasis is a mirror image of the frequency response curve of the input signal deemphasis.  The linear range of the frequency response curve of the control signal preemphasis is selected to provide an encoder output signal having a substantially flat response. The frequency response curve of the control signal deemphasis is a mirror image of the frequency response curve of the control signal preemphasis.  The amount of preemphasis is maximized to the limits of the recording medium, typically ranging from 0 db to 20 db.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for breaking up solidified particulate material in a storage container has a housing lowerable into the container on the lower end of a suspension element.  A flailing element holder is rotatably mounted on the housing for rotary movement relative thereto about a substantially vertical axis when the housing is sus-pended in the container.  An elongated flexible flailing element projects from the holder, and the holder is rotated relative to the housing to cause the flailing element to engage and break up solidified particulate material when the housing is suspended in the container.          The housing has a torque-balancing device mounted for rotation relatively thereto about a substantially verti-cal axis, and the torque-balancing device is rotated in a direction opposite to the direction of rotation of the flailing element holder to substantially balance torque produced by rotation of the flailing element holder and thereby substantially prevent angular movement of the housing about a vertical axis when the flailing element holder is rotated.

Abstract: ABSTRACT          A water distiller assembly which provides for an efficient distillation process wherein steam generated in a boiling chamber is delivered to a steam condensing chamber where steam condensation is carried out by the combined effect of water cooling and air cooling.  The resulting distilled water is stored in the steam condensing chamber where it is kept hot by the incoming steam for hot serving while at the same time helps in condensing the steam it comes into contact with.  Water vapour emanating from the surface of the hot coolant water is also condensed and collected.          Operating temperature of the coolant water may be adjusted to suit room temperature demands.  The distillation process is made automatic, continuous and self-limiting by the use of two simple float controls and a thermostatic water outlet valve.  The essential components comprise a cooling tank with its bottom half immersed in the space contained by a condensing chamber; a heating element and a boiling chamber resting on a bracket support such that feed water is supplied from the cooling tank to the boiling chamber via a connecting conduit and such that water levels in the cooling tank and boiling chamber are maintained at the same level; a cover and a water collecting trough on top of the cooling tank serve to collect extra distilled water and the water is drained to the condensing chamber via a vertical conduit.

Abstract: ABSTRACT OF THE DISCLOSURE A jointing connector made from a sheet metal blank for connecting two to four wood members such as 2 x 4's.  The connector includes a palm portion, and a finger portion with six distinct finger members.  Each finger may be bent in the field by workmen to accommodate the particular jointing of the wood members.  Preferably, the connector is bent in a U-shape at the factory.  Three types of nail openings are provided including circular, slotted and directional slotted tab openings.  The dif-ferent types of openings with the configuration of the connector enable workmen to use the same connector in nearly a universal application to all types of jointing configurations.  Further, the use of the special nail openings and the connector permit many of the nails to be used in double shear applications so that the connection value is doubled.

Abstract: The method consists of a cold pilgrim rolling mill to effect a recoil movement of the chuck upstream followed by a return to its original position, at least once per rolling cycle. The period during which the chuck is withdrawn with respect to its rolling position is used advantageously for example to carry out the rotation of the chuck and/or to cause a lubricant under pressure to circulate between the chuck and the pipe. The method is applied particularly to the rolling of pipes with a large section, with high reduction rates.

Abstract: Abstract.     Square or rectangular clean cut flakes, wafers or strands of a uniform thickness, width and length, with edges extending at right, acute or obtuse angles to the surfaces are produced by an apparatus in four distinct operations, comprising the veneer slicing, cutting of the veneer sheets into veneer strips, chemical or laser beam treatment and flake cutting.  The chemical or laser beam treatment is applied to the edges of the veneer strips which run transversally to the direction of wood fiber and the applica-tion takes place before the veneer strips are cut into flakes.          The treatment may be introduced for the purpose of sealing of the opened ends of wood fiber against water or water vapour absorption or to fortify and strengthen the flakes, wafers or strands against breakage along the wood fiber, to enhance the properties of the flakes, wafers or strands for the purpose of effective orientation in an electrostatic field or in other means of orientation in the production of agglomerated structural boards and lumber, to enhan-ce the detectability of the position and degree of orientation of the flakes for the purpose of quality control, to colour-code the flakes, wafers or strands for aesthetical, decorative or other re-asons dictated by the manufacturing process or by the market.  The moisture content and the mass of the flakes produced may be accur-ately monitored and the measurements processed in a computer and used for an effective control of the drying process.
