Patent GB-2251064-A (GB)
Title: Air conditioning unit
Inventor: DHANJAL MANMOHAN SINGH
IPC: F24F1/02
Filed: 1990-12-20
Abstract: An air conditioning unit for a room comprises a refrigeration system including an evaporator 14 and a condenser 13 over which air is drawn by fans 5, 6, and means for varying the air flow through the unit such that, in use, air passing to the room either flows over evaporator 14 to cool the room or over condenser 13 to heat the room. In the illustrated construction the air flow is changed by a valve 17. For cooling. the valve is set to the position shown so that air sucked from the room by the fan 6 passes to the outside atmosphere via apertures 21, 24 (arrows B), and air drawn from the atmosphere by the fan 5 passes over the evaporator 14 to be cooled, and then into the room via aperture 18 and outlet 9 (arrows A). In the heating mode, the air valve is pivoted clockwise through 90 DEG  so that air withdrawn from the room via inlet 10 is heated by the condenser 13 and is returned to the room via the outlet 9, and outside air is drawn over the evaporator 14 and exhausted via aperture 24. Air passing to the room may be further heated by an electric element 16, and a part 15 of the evaporator may be positioned as shown to dehumidify room air recirculated from inlet 10 to outlet 9 in the heating mode of the unit. Alternatively, valve 17 could be replaced by a fixed member in the position shown, air flow variation then being achieved by reversing the direction of the fans 5, 6. <IMAGE>

Title: Apparatus for classifying particles of tobacco and the like
Inventor: STUDT STEPHEN
IPC: B07B13/16
Filed: 1991-08-27
Abstract: Apparatus for separating longer tobacco particles from shorter tobacco particles has an elongated vibratory trough for the advancement of a stream containing a mixture of shorter and longer particles from a delivery conveyor to a collecting receptacle. The upper side of the bottom wall of the trough is formed with longitudinally extending depressions which receive and align the particles of the advancing stream, and the bottom wall is formed with one or more transversely extending slots which extend across the depressions and permit shorter particles to descend into a second trough from which the shorter particles return into the distributor of a cigarette rod making machine. The properly aligned longer particles advance across the slot or slots and enter the receptacle. The slot or slots make oblique angles with the direction of advancement of particles along the bottom wall of the vibratory trough to ensure that any particles which happen to be caught in a slot are moved sideways and out of the way into a third trough so that the next-following shorter particles can enter the respective slot or slots. The stream consists mainly of longer particles and is obtained as a result of classification of a mixture of shorter and longer particles in the distributor.

Title: Stressing mechanism for tent roof.
Inventor: BENNETT LAURENCE JOSEPH
IPC: E04H15/32
Filed: 1992-09-24
Abstract: A stressing mechanism is provided for a tent which comprises at least two elongate members (1) each pivotally connected at one end (5) to different fixed points of a tent and at the other end to each other at a coupling point (3). Struts (2) are each pivotally mounted at one end to a respective elongate member(1), and at the other end to each other at a second coupling point(4). By forcing the second coupling point towards the first coupling point, the elongate members are induced to flex until a point of maximum flexure in the members (1) and maximum compression in the struts (2) is reached. Further motion of the second coupling point is accompanied by reduced flexure and compression. The coupling points are held together by a locking force resulting from the reduction in flexure and compression forces. <IMAGE>
