Abstract: A carrousel (2) has a plurality of spaced apart holders (50) mounted on its outer periphery. Each holder receives a plant unit (90) including a plant with foliage (92) and a root/soil mass (94) received in a container (96). As the carrousel (2) turns, a cam (70) carried by each holder (50) engages a ramp (78) to cause the holder (50) to grip the container (96). The holder (50) then conveys the plant unit (90) through first and second cutting stations (4, 18) at which top and side portions of the foliage (92), respectively, are trimmed. The trimming is accomplished by flail cutters (6, 20, 21). At the side cutting station (18), the plant unit (90) moves between a pair of cutters (20, 21), and a rubber tire (84) rotates the holder (50) and plant unit (90) to provide cutting all the way around the plant unit (90). After exiting the second station (18), the holder (50) releases its grip on the plant unit (90).

Abstract: Provided is a method of providing warm air to the intake of a engine of a vehicle to improve fuel economy and reduce emissions of said vehicle. The method includes the steps of:transferring warm air directly exiting a radiator to an air intake of an engine using a variable vane which flexes and rebounds to continuously adjust an amount of warm air being supplied to said air intake in response to various engine loads;allowing said variable vane to flex and rotate an air deflection surface of said variable vane to a position which supplies an increased volume of warm air to said air intake as a warm air load against said air deflection surface is increased; andallowing said variable vane to rebound and rotate said air deflection surface to a position which supplies a decreased volume of warm air to said air intake as a warm air load against the air deflection surface of said variable vane is decreased. The invention also provides an apparatus for practicing the method.

Abstract: A socket (1) forms part of a flat-pin connector designed for 19" racks. Mounted on it by means of soldering tabs (3) is a standard circuit board (2) which is fitted in a housing (9). The housing (9) has two parallel walls (13,14) and is closed off from the socket by a half-frame (16). The part of the socket (1) facing towards the circuit board (2) has a central section (6) which not only carries the soldering tabs (3) but also acts as a stop for the circuit board (2). The dimensions and position of this central section (6) are such that the housing wall (13) which covers the solder side of the circuit board does not extend out more than a distance defined by the distance between the pin array and the side of the socket (1), so that the whole of the rest of the width comprising distances is available for components and the other wall (14).

Abstract: With direct current/direct current converters of modern construction, which can be operated at frequencies as high as 500 kHz, the number of secondary windings that are necessary decreases with simultaneously high currents, so the necessary voltage can be generated by a single winding, or even by less than one winding. A push-pull converter exhibits, for example, a transformer with a center limb (19) and two outer limbs, and that contains on the secondary side two coils (29, 30), each of which consists of a single, complete winding with one center tap (B, E) each. These coils are placed around the center limb (19) in such a way that the two center taps (B, E) come to be located opposite each other in two openings (18) between the outer limbs.

The second secondary winding (tertiary winding) and the control device are connected within the synchronous rectifier to provide protection for the two MOSFETs from destruction caused by reverse feed.

A third and fourth MOSFET are provided whose source terminals are connected to the gate terminals of the first and second MOSFETs and to a second of two output terminals of the rectifier through a resistor. A Schottky diode is connected in parallel with the drain and source terminals of the first MOSFET with the cathode of the Schottky diode and the drain terminal of the first MOSFET being connected to a first of the two output terminals. A switching block circuit is connected between the parallel connection of the Schottky diode and the first MOSFET and the second output terminal of the rectifier. A capacitor is connected between the gate terminals of the third and fourth MOSFETs and the second output terminal of the rectifier. The output of a logic unit is connected in parallel with the capacitor.

Abstract: Ski apparatus two outer skis coupled to a third ski, located between the two outer skis, by four cranks, connected as a front pair and a rear pair. Each crank has a gear on one end and a free end. The free end of a crank is attached to a journal box on an outer ski to permit the crank to rotate freely. The gear of the crank from one outer ski meshes with the gear of a crank attached to the other outer ski, coupling the cranks in pairs and causing the cranks to rotate in opposite directions. The gears from each pair are contained in a gearbox attached to the third or middle ski. The cranks can be stiff or resilient and, if resilient, includes an elbow joint which is spring biased to force the middle ski below the outer skis.

Abstract: A starter plant (10) is planted in soil (17) in a bottomless container (18), which is placed on a support surface (28). The plant is allowed to grow in a controlled environment until a time in its growing season when its root system is sufficiently developed to hold the soil (17) in the container (18) when the container (18) is removed from the surface (28). Then, the plant and the container (18) are planted as a unit in soil (30) in a field. The plant is allowed to grow to full size in the field, where it develops a densely rooted basal plate (32) inside the container (18) and feeder roots (34) that extend below the bottom of the container (18) into the soil (30). The plant is harvested from the field by undercutting the feeder roots (34) and removing the container (18) and the plant as a unit from the soil (30). The foliage (12) may be trimmed to a volume no bigger than the container (18), and the trimmed plant (38) may be stored or shipped.
