Abstract: ABSTRACT OF THE DISCLOSURE        A dual circuit brake valve for an articulated vehicle is responsive to a pressure signal provided by the system tractor protection valve to provide a full brake application in both the primary and secondary braking circuits actuating the front and rear wheel brakes of the vehicle respectively when the portions of the articulated vehicle are connected for movement together.  A proportioning piston is responsive to the pressure signal to proportion braking pressure in the secondary when the towing portion of the vehicle is operated in the "bobtail" mode without the towed portion of the vehicle.  The brake valve includes mechanism for mechanically actuating the secondary circuit valve to provide a full brake application under emergency conditions during operation of the vehicle in the bobtail node.

Abstract: Abstract A control device is provided in a multi-roll press (22 to 24) of a calender, intended for the glazing of a continuous thin web, such as a paper web, which press comprises a compensated upper roll (22), a compensated lower roll (24), and at least one press roll (23) fitted between these rolls.  The control device itself comprises a press-load control circuit (B, C, D, 11, 14, 15; A, 29, 30), a compensation circuit (E, 16, 17) for the upper roll (22), as well as a compensation circuit (F, 27, 28) for the lower roll (24).  According to the invention, both of the compensated circuits (E, 16, 17 and F, 27, 28) are, via their own feedbacks (12 and 13), connected to the control circuit (B), which is fitted so as to select the most slowly changing one from among the signals of the feedbacks (12 and 13) and to brake down the roll (22 or 24) whose compensation is being varied most rapidly.  By means of the invention, the calender will always be loaded in a constant way, whereby a better paper quality and constant running values are obtained.

Abstract: Abstract of the Disclosure A local area network for interconnecting terminals and other users and data processing systems and other service providers over a communications link.  The users and providers connect to the communications link by means of interface units each of which may connect to several users or providers.  The interface units communicate over the communications link by means of messages.  When a user requires the use of a service, the interface unit establishes a virtual circuit between it and the interface unit connected to the service provider and a service session which allows the user and the service provider to communicate over the virtual circuit.  If several users connected to the one interface unit as the first user require services provided by providers which connected to the same interface unit as the first provider, they communicate in sessions over the same virtual circuits.  The session messages are accumulated into single virtual circuit messages that are acknowledged in unison by the receiving interface unit. Each virtual circuit in the users' interface units includes a timer which reset when a message is transmitted over the virtual circuit and a data waiting flag set whenever data is present to be transitted over the virtual circuit.  The interface units are inhibited from transmitting over a virtual circuit unless the timer has timed out and the data waiting flag is set.

Abstract: "METHOD AND APPARATUS OF MARKING A HOT STEEL SLAB"    ABSTRACT OF THE DISCLOSURE   A method of applying a visible mark on a hot steel slab is described. The adherence of the marking composition to the slab surface can be improved by removing locally iron oxide therefrom, followed by the step of locally cooling down the surface to prevent secondary oxide growth. This is done by first directing a water jet of high pressure at an acute angle to the slab surface immediately followed by a gentle water stream of low pressure. After this conditioning of the surface, the mark can be sprayed thereon.

Abstract: ABSTRACT            The  ice warning system comprises a diaphragm {2} into vibration at one of its frequencies of resonance by a piezoelectric cell (3). The diaphragm (2) is thermi-cally coupled to a metallic plate (4) alternately cooled and heated respectively below and above the ambient temperature (Tu) by peltier elements (8) connected to a reversible DC current generator (11). A microprocessor (12) measures the variation of the resonance frequency caused by a deposit of ice on the diaphragm (2) during the cooling or heating periods and delivers an alarm signal whenever any variation of the frequency reaches and/or exceeds a predetermined value. The microprocessor (12)  controls also the period,  the magnitude  and the direction of  flow of  the current from the current generator  (11)  in dependence on the  ambient tempera-ture and the temperature of the diaphragm. The ice warning system is preferably utilized in the aeronauti-cal field for signaling the likelihood of natural ice formation on the engines and the wings of aircrafts.

Abstract: ABSTRACT In the production of ethanol by continuous fermentation in a fermentor with continuous stillage recirculation to the fermentor, the fermentation liquid continuously being withdrawn from the fermentor is first strained in a straining step for separation of coarse solid particles.  Then the fermentation liquid is separated in a yeast separation step, from which a yeast stream is recirculated to the fermentor and a yeast-free stream is fed to a primary distillation step.  From the bottom stream from the distillation step a portion is recirculated to the fermentor and another portion is subjected to final stripping in a secondary distillation step.  By installing a further centrifugal separation step in the stream, which is fed to the distillation step, or in the bottom stream which leaves the distillation step, finer inert solid particles can be removed from the circulation circuit comprising the distillation step and the fermentor.  Thereby results a considerable saving in separator capacity in the yeast separation step and an improved fluidity in the system.

Abstract: DISPENSING CLOSURE CONSTRUCTION                     Abstract A dispensing closure construction of the type hav-ing a base part or body that is adapted to be held cap-tive on a container neck, and a sealing cap and integral hinge connected to the body. The body has an off-center discharge orifice and a high, domed top portion behind the orifice and extending above the level thereof so as to channel product from the top portion back toward the orifice after the container is used and returned to an upright position. A continuous sealing shoulder on the body engages the inner cylindrical surface of the seal-ing cap near its edge when the latter is swung to its closed position, thereby to minimize the possibility of water or other liquid from entering the area around the underside of the cap. A rib carried on the underside of the sealing cap is receivable in a recess in the domed top portion, and can engage opposed, facing shoulders thereof so as to limit relative turning between the cap and body. The rib and recess are adjacent the location of the hinge. The advantage of the present construction over the devices of the prior art is that there is an improved seal around the area at the underside of the sealing cap. Also, there is less possibility of inad-vertent damage to the hinge if torque from automatic capping equipment is applied directly to the cap.

Abstract: POWER SNARE          ABSTRACT OF THE DISCLOSURE            Animal traps are usually difficult to sterilize in order to remove human odour therefrom and difficult to hide when setting and often contain moving parts, tubes, pins and the like.  The present device consists of a pair of spring arms made of heavy wire with a hairpin spring at the junction thereof.   Eye loops are formed one on each distal  end of  the  arms  and  one of these has a slotted semi-circular plate welded otherwise secured into the base of the eye.   A freely running snare loop is provided on one end of a standing part,  in which part extends through the slot in the disk or plate and through a cotter pin assembly spanning the other eye and termi-nates  with  a  ferrule  outboard of the  other  eye.   A trigger block is secured to the standing part inboard of the slotted disk when the trap is set with the two arms close together and being urged apart by the spring.  The snare loop is adjustable to catch the shoulders of the animal, and the movement thereof disengages the trigger block from the slotted disk and allows the arms to spring apart tightening the snare loop and striking the animal a heavy blow with the eye of the one arm.
