Abstract: Verge unit is a symmetrical tapered channel converging toward one end and diverging toward another end. The unit 1 has two frangible portions which are disposed inwardly at the divergent end the removal of one of which portions allows the unit to be converted into a right hand or a left hand unit for use on a right hand or left hand verge of a roof. The units are placed over the free ends of tiles on a verge so that each divergent end of a unit is overlapped by a convergent end of an adjacent unit, thus providing a stepped line following the line of overlapping tiles along the upper edge of the verge and a straight line running along the lower edge. Verge units may be used for covering the free ends of tiles on tiled roofs to provide an aesthetically pleasing finish to the verge ends of tiled roofs and to prevent the ingress of rain and snow between the tiles.

Abstract: A baler has winding elements for forming a bale of crop. A formed bale is bound with binding material such as twine or wire from a binding mechanism. When a bale is fully formed, a cable is pulled by the operator of the tractor towing the baler which actuates the binding mechanism and simultaneously operates a change-speed gear to increase the speed of the winding elements. The bale thus rotates faster during binding than it does while it is being formed. This reduces time required for binding. When the bale has been bound, it is discharged through a door which pivots upwards for this purpose. Pivoting of the door pulls a further cable which returns the change-speed gear to the lower speed position and actuates the binding mechanism so that the next bale can be formed. The bale chamber is substantially cylindrical with rotatable elements around the interior of its curved sides.

Abstract: The invention relates to a fuel supply device for model aircraft. To produce an excess pressure in the fuel tank in order to force the fuel into the engine, the fuel tank is connected to an excess pressure chamber (4) of an exhaust constructed in the form of a silencer. The casing (1) of the exhaust is subdivided by partitions (5, 6) into a number of chambers lying axially one behind the other. The excess pressure chamber (4) and the chamber (3) disposed therebehind in the direction of flow and directly connected to the exhaust gas outlet (9) are interconnected via a valve arrangement (16-18) which so operates after the fashion of a non-return valve that the valves are throttled in dependence on the inclined position of the exhaust. During climbing throttling is particularly heavy, so that a heavier excess pressure is formed in the chamber and therefore higher delivery pressure acts on the fuel in the tank. In this way the engine is supplied with enough fuel even during climbing.

Abstract: An exhaust apparatus connected to a V-type internal combustion engine which is mounted in an engine compartment in a front part of a vehicle. The exhaust apparatus comprises a front exhaust manifold and a rear exhaust manifold connected to banks of the V-type engine respectively, an exhaust assembly connected to the exhaust manifolds and a catalytic converter interposed in the exhaust assembly. The wall thickness of the front exhaust manifold is made thinner than that of the rear exhaust manifold. By the thin front exhaust manifold, the heat capacity of the front exhaust path extending from the front exhaust manifold toward the catalytic converter is lessened, thereby suppressing the dropping of temperature of the exhaust gas flowing through the front exhaust path. As a result, the dropping of temperature of the exhaust gas reaching the catalytic converter is suppressed as a whole, and a catalyst in the catalytic converter is warmed up quickly to a required temperature.

The flow of exhaust gas having the soot particles emerges into the hot combustion chamber through radial outlets transversely to the direction of extension of the ignition flame that is propagating through the overflow opening. The soot particles that are supplied are for the most part burned in the hot combustion chamber, and the remainder is burned in the labyrinthine conduits.

By the use of simple 2/1 shut off valves the switching over device is generally simplified to a substantial extent.

A servo chamber is defined behind the primary piston, and pressurisation of the servo chamber from a source of pressure fluid is controlled by a valve in response to an input force applied to the primary piston. The valve comprises a spool operated solely by pressure in the primary space and a bias force from servo pressure in a bias chamber and a spring. The secondary piston has a smaller effective area than the primary piston, so that the pistons are in abutment in their retracted positions. To reduce pedal travel, one of the brakes of the primary circuit can be supplied from the servo chamber instead of the primary pressure space.

Abstract: A method and apparatus for implementing a thermodynamic cycle, which includes the use of a composite stream, having a higher content of a high-boiling component than a working stream, to provide heat needed to evaporate the working stream. After being superheated, the working stream is expanded in a turbine. Thereafter, the expanded stream is separated into a spent stream and a withdrawal stream. The withdrawal stream is combined with a lean stream to produce a composite stream. The composite stream evaporates the working stream and preheats the working stream and the lean stream. The composite stream is then expanded to a reduced pressure. A first portion of this composite stream is fed into a gravity separator. The liquid stream flowing from the gravity separator forms a portion of the lean stream that is combined with the withdrawal stream. The vapor stream flowing from the separator combines with a second portion of the composite stream in a scrubber.

In one embodiment, the driver comprises a piston for pushing the ice tubes off of the evaporator tubes. In another embodiment, a helical driver moves the ice tubes off of the evaporator tubes.

Abstract: The baffle for controlling flow of chilled air through the divider wall between the frozen food and fresh food compartments of a refrigerator is coupled to a motor driven cam which indexes the baffle open or closed in response to commands from a conventional control unit. Electrical switches for controlling the compressor and defrost heater of the refrigerator are positioned axially along the cam to be operated selectively by concentric cam surfaces as the cam is rotated by the motor. A cam follower engages another concentric cam surface to operate another set of switches to apply rotational positional feedback signals to the control unit. The cam surfaces are shaped and the baffle is coupled to the cam such that unidirectional rotation of the cam in response to commands from the control unit operates the switches synchronously with the baffle to selectively cool the frozen food and fresh food compartments and defrost the evaporator.
