Patent CA-1130149-A (CA)
Inventor: BAHIA HARDEV S
IPC: D02G1/08

Abstract: ABSTRACT OF THE DISCLOSURE     A filament yarn of greater than 60 per cent extensibility is combined with a carrier yarn.  The combined yarn is false-twisted under tension in a unit employing rotary friction elements so that the filaments of the extensible yarn break intermittently while the carrier yarn remains intact to pro-duce a spun-like textured yarn.  The tension during false-twisting may be increased to a level at which the broken fila-ments snarl and form slubs in the yarn.  The process may be carried out with no heat setting of the false-twist to form crimps. Suitable extensible yarns include undrawn and partially-orientated yarns, polyamide and polyester yarns, and suitable carrier yarns include fully-drawn filament yarns and spun yarns.

Abstract: ABSTRACT OF THE DISCLOSURE A system is provided for precise monitoring and control of the carbon content of the atmosphere of a furnace such as a carburizer used in the heat-processing of steel parts.  According to the system an apparatus is provided which includes a sampling system for withdrawing a gas sample from the atmo-sphere within a furnace and an analyzer for producing signals indicative of the partial pressures of at least two gaseous components such as carbon dioxide and carbon monoxide.  The analyzer preferably utilizes selective absorption of narrow-band infrared radiation signals in determining these signals.  A proces-sor combines the signals indicative of partial pressures with parameters obtained from measurements of furnace temperature, and calculates carbon potential of the furnace atmosphere.  The processor output is coupled with an atmosphere control which maintains desired levels of carbon potential in the atmosphere of the furnace by, for example, regulating the flow of an enriching gas to the furnace.

Abstract: ABSTRACT                 The invention is concerned with a shank adaptor for a rock-drilling machine provided with at least one side flushing hole which connects an axial flushing hole of the adaptor with the outside thereof and which, together with the axial flushing hole, serves as a passage for transporting flushing medium.  The side flushing hole has an oblong cross-sectional shape with the longitudinal axis of the oblong parallel to the longitudinal axis of the shank.  The shank adaptor of the invention enables stress concentration at the outer edge of the side flushing hole to be reduced while decreasing hole-edges sensitive to fractural impressions by half, which also results in a reduction in the probability of fatigue cracks caused thereat by the rotary bending forces on the adaptor.

Abstract: ABSTRACT A compensator is disclosed for centering a frame supported steerable member comprising part of the steer-ing means for a vehicle.  The compensator is connected between the frame and the steering means and comprises a cylinder containing a pair of pistons and an actuator for engaging the pistons in response to movement of the steerable member.  A fluid system provides fluid resis-tance to off-center piston movement and fluid force for return piston movement and includes means for indepen-dently varying both the resistance and the return force. The compensator may include trimming means for remotely varying the center position of the steerable member and means for controlling the rate of both turning and return movements.  Optional valve means provide for deactivating the compensator manually or in response to power steering system failure, overpressurization, or vehicle speed.

Abstract: Abstract A configuration of two transistors and two capaci-tors provides a current mode second-order active filter for IC implementation with low-pass, bandpass and high-pass capabilities.  The filter frequency is tunable over a wide range, independently of filter Q and gain, by varying a DC bias current.  The filter can provide one-port impedance functions, and two-port voltage, cur-rent and impedance transfer functions.  With the addition of a second biasing current source, the filter Q can be controlled by adjusting the ratio of the two biasing current sources.  Enhanced dynamic range and large-signal performance can be achieved by the addition of linear resistors, with trade-offs in tunable frequency range and frequency linearity.

Abstract: ABSTRACT:         Prerecorded video discs will generally be provided with a programme which has originally been recorded on film,which programme is transformed into a television signal by scanning the film frames. Owing to the difference between the standards for film and television employed in the United States consecutive film frames always result in sets of un-equal numbers of fields on the record carrier. Pre-ferably an indication signal is added to each set of fields on the record carrier. The read apparatus comprises detection means for detecting said indi-cation signal. This signal is used to ensure that in the still-picture mode, during which the same two fields on a track circumference of the record carrier are repeatedly read, two fields are read which belong to the same set and consequently stem from the same film frame,

One side of the tape may be adhesive-coated, and the other side may be coated with a thermochromic paint.  The tape is wrapped around a substrate, and is particularly adapted, by reason of the pleats, to be wrapped around a substrate of non-uniform cross-section, e.g. a splice in a telephone cable.  On heating the tape to its recovery temperature, the pleats disappear and the tape shrinks longitudinally to tightly cover the substrate.  The tape may additionally comprise integral heating means.

Abstract: ABSTRACT           A method and apparatus for continuously separating solids and liquid in a solids-liquid mixture are disclosed.         In accordance with the invention, a separation zone for separating solids and liquids from a solids liquid mixture is provided in which the mixture is subjected to centrifugal force under low shear forces and low turbulence.  In this zone, the flow rate is maintained to be less than the terminal settling velocity of the solids in the mixture.  Further in accordance with the invention, the mixture is introduced into the separation zone from a zone of higher turbulence and higher flow rate than those of the separation zone, a minor part of the mixture in the other zone being removed to the separation zone.  The major part of the mixture is removed from the other zone and discharged and returned to the mixture source in such a manner as to aerate the returned mixture.         The separated solids are returned to the mixture source with the major part of the mixture.  The separated solids and liquid are removed from the apparatus of the invention con-tinuously.  The invention is particularly useful in obtaining a highly clarified centrate from sewage sludge.

Abstract: ABSTRACT     Alditols such as 15-40 W % sorbitol solution in water are catalytically hydrocracked in a fixed bed catalytic reaction process using an active nickel catalyst to produce at least about 30 W % conversion to glycerol and glycol products.  The feedstream pH is controlled to between 7 and 14 by adding a basic promoter material such as calcium hydroxide to prevent damage to the catalyst.  Useful reaction zone conditions are 400-500°F  temperature,   1200-2000  psig  hydrogen  partial pressure, and liquid hourly space velocity of 1.5 to 3Ø  To maintain desired  catalyst activity and product yields,  the catalyst  is regenerated  to provide catalyst age within the range of 20-200 hours.   The reaction products are separated in distillation steps at successively lower pressures and unconverted alditol feed is recycled to the reaction zone for further hydrogenolysis to produce 80-95 W % glycerol product.         Sorbitol conversion is maintained preferably at between about 30-70 W % by catalyst regeneration following 20 to 200 hours use, comprising washing to remove deposits and heating with hydrogen at 500-600°F temperature.   Countercurrent flow of feed  and  hydrogen  in  the  reaction  zone  can  be  used  if desired,  particularly  for  achieving  higher  conversion  of alditol feed to glycerol products. 2?
