Title: Bogie for rail vehicles
Inventor: AHLBORN GUNTER
IPC: B29C65/22
Filed: 1989-11-24
Abstract: ABSTRACT OF THE DISCLOSURE                BOGIE FOR RAIL VEHICLES (20,514) A bogie for rail vehicles with a low-seated loading ramp, comprises at least two sets of wheels with a small axle base and a bogie frame comprising lateral cheeks and a traverse 2 extending between every two axles. The sets of wheels 4 are clamped into the bogie frame by means of axle bearings 3, and the bogie is connected to the vehicle frame merely by means of one carrying leaf spring 10 arranged laterally and lengthwise carried in suspension rings 11 and has a false pivot and has catches which limit the movement of the bogie relative to the rail vehicle.  The rocking or swaying properties of the bogie are optimized to improve the running behavior on straight stretches as well as on curves while providing the required transverse play of the bogie.  The construction is made more favorably by employing long suspension rings.  The power transfer from the loading ramp through the carrying leaf spring to the bogie is improved by carrying leaf springs on spring brackets arranged laterally between the structure gauge and the freight hold of the vehicle and on the outside of the lateral cheeks and above the rails.

Abstract: ABSTRACT    A roaster for coffee beans or the like admits the beans into a roasting air stream (31, 23, 32) at an air stream entrance (24).  The air stream transports the beans from entrance (24) in an air stream path (26, 36) to an altitude (36) from where they are directed to return to entrance (24) by falling into a hopper having side wall (13, 14) and a constriction (22) which controls the rate of admission of the beans into the air stream.  In preferred embodiments the beans are admitted into a horizontal air stream with a component of velocity in the air flow direction and roasting air is also admitted to the hopper directly (46) or indirectly (44, 45) via wall perforations (19, 20).

Title: Wire grid subceiling panel
Inventor: BLITZER JACOB H
IPC: E04C2/42
Filed: 1990-04-17
Abstract: ABSTRACT OF THE DISCLOSURE        Ceiling panels, formed from metal rods welded together in a grid pattern, are easily installed in suspended subceilings of the type in which panels are supported on bottom flanges of a framework of inverted T-bar rails. In a lower layer of the panel, an array of spaced parallel rods is tied together across each end by an end rod to form a perimeter which fits within a cell opening of the inverted T-barsupport framework, while rods in an adjoining upper layer of the panel, oriented perpendicular to the rod array in the lower layer, are made to extend beyond the lower layer perimeter so as to support the panel, along two opposite panel edges, upon the upper side of bottom flanges of the support framework rails. The perimeter rods in the lower layer in combination with with the exposed portion of the support rail flanges produce the finished effect of a uniform border around each panel. The wire grid panels may be utilized exclusively in a subceiling for an "open plenum" effect or intermixed with conventional solid panels such as acoustical board to provide desired architectural patterns. For noise reduction or avoiding an open plenum view, some or all of the wire grid panels in a subceiling may be overlaid with standard acoustical board. Also, the wire grid panels may be utilized in combination with special rail flange coverings such as the MINIATURE CEILING T-BAR COVER CAP, U.S. Patent No. 4,848,054 to Blitzer and O'Toole.

Patent CA-2050659-A1 (CA)
Title: Feed conditioner apparatus
Inventor: LUCAS RICHARD V
IPC: A23N17/00
Filed: 1991-09-04
Abstract: Abstract of the Disclosure The conditioner of the present invention treats feed with steam and includes a plurality of steam lines that can inject steam into a chamber having inlet and outlet openings. Located within the chamber is a rotatable shaft supporting a helical stainless steel ribbon arranged coaxially with the shaft and extending for approximately three quarters of the length thereof. When the shaft is rotated, the ribbon acts as a conveyor and moves the feed in a first direction. The shaft also supports a plurality of paddles which create a counterflow of feed in a direction opposite to said first direction to cause the feed to mix with the steam. Also mounted on the shaft are a plurality of beaters which agitate the feed steam mixture to create an even and continuous discharge of feed. A weir is mounted upstream of the discharge opening to prevent escape of the steam by ensuring that the upstream portion of the chamber is filled with feed. The weir also provides an even flow of feed to the outlet opening. The weir and the agitation of the feed caused by the beaters retards the escape of the hot steam from the chamber such that the temperature level in the chamber can be maintained. By adjusting the speed of rotation of the shaft, the position of the paddles, the amount of steam injected and the size of the weir, the performance characteristics the conditioner can be varied.
Patent CA-2051866-A1 (CA)
Title: Call set-up and spectrum sharing in radio communication on system with dynamic channel allocation
Inventor: KOOHGOLI MAHSHAD
IPC: H04M1/72511
Filed: 1991-09-18
Abstract: The call set-up technique of this invention is characterized by the use of channel information from both base station and subscriber terminal in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen.  Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal.  The set of channels under consideration by the subscriber terminal is a subset of the entire set of channels allocated to the service.  This subset is comprised of those channels having little interference, as measured by the base station, and which, additionally, are not reserved exclusively for stationary, fixed-allocation services in the geographic location of the base station.  The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal.  The technique also facilitates sharing of the radio spectrum with stationary, fixed-allocation services because there is no need to program each subscriber terminal to avoid the spectrum allocated to the fixed service.
