Abstract: 1,118,500. Transistor amplifying circuits. LEEDS & NORTHRUP CO. 5 Aug., 1966 [31 March, 1966], No. 35247/66. Heading H3T. [Also in Division H1] A chopper-type amplifier is provided with a balanced input, a field-effect transistor being used as chopper; break through of the squarewave chopping pulses through the inherent capacity of the transistor is prevented by means of a balancing capacitor. In one embodiment, a gating waveform from generator 15, Fig. 1, is applied to the gate of FET 11, the source-drain path of which comprises a variable shunt on a bridge network comprising balanced amplifier input resistors 20A, 20B, signal source 12 which has internal resistance 13, and balancing resistor 17. Breakthrough of the gating waveform via the capacity 23, 28 between gate and case of the FET is prevented by means of balancing capacitor 22 connected between gate and drain. An unbalanced amplifier may be fed via a transformer with a centretapped primary replacing resistors 20A, 20B (Fig. 2, not shown), and the chopper may be connected in series instead of shunt (Figs. - 3B, 3C, not shown). With transformer input, a pair of choppers may be used in push-pull (Fig. 4B, not shown); details of the transformers are given in the Specification (see Division H1). Square wave generator.-Square waves are generated by means of a pair of transistors 35A, 35B, Fig. 5, cross-coupled over blocking capacitors 36 and differentiating circuits 41A, 41B; a resistor 39A, 39B respectively is connected between base and collector of each transistor. Clipper diodes 40A, 40B limit the extent to which the base of each transistor is driven by the feedback from the other; two outputs of opposite phase are provided, in each of which networks comprising a resistor 45, diode 46 and Zener diode 47 are provided for the purpose of producing chopper-drive signals of desired level and polarity.

Abstract: A shift mechanism comprises a shift lever adapted to effect the engagement of transmission gears. The lever has a main shaft which is rotatable about its axis and pivotable in a plane containing its axis. Shifting is therefore effected by a combination of rotary and straight line movements. A rigid member extends from a bottom portion of the lever main shaft to a location radially spaced from the main shaft axis to effect a selection of gates of the transmission when the shift lever is rotated.

Patent SE-457483-B (SE)
Title: Throttle for gas flow regulation
Inventor: HELGESSON GOESTA
IPC: B08B15/04
Filed: 1983-02-17
Abstract: The device comprises a throttle (20-22) which for variation of the channel characteristics is adjustable between different positions to provide passage for the gas. A drive is provided for the throttle adjustment, and comprises a pressure controlled component. This component is operated by the difference between a relatively stable pressure, e.g. that atmospherical, and pressure in the channel or another channel connected to it. The pressure controlled component executes a movement which is transmitted as an adjustment motion in the throttle (20-22). The main drive (1) comprises a suction chamber which can be connected to one of the channels (16-18), and which contains a wall of highly elastic membrane. This membrane changes shape through pressure variations in the suction chamber, and via force transmission mechanism produces the regulation of the throttle (20-22).

Title: Primary release valve
Inventor: KVIST A
IPC: F16K11/02
Filed: 1990-05-18
Abstract: A hydraulic valve constructed as a multi-way valve with pressure medium feed through the valve in two parallel ducts. Closing and opening of ports 1, 2, 3, 4, T to the various ducts is performed by a combined piston/slide 6. The piston 6 is provided with cams 7, 8, 9 which, in interaction with throttling edges A, B, C, D, E inside the valve space, where the piston 6 runs, open or close the ducts and connections to the valve. Operation of the piston 6 is brought about by applying a control pressure at one end of the piston, where the piston is provided with a pressure area. The control pressure can be produced in any way. At the opposite end of the piston, the piston bears against a valve seat F when control pressure is applied to the piston. This valve seat seals effectively between a duct inside the valve seat and a port outside. At the same end of the piston, there is also a return spring 10 which returns the piston to the starting position when control pressure is not applied to the piston. The object of the valve is to produce a valve in which two ducts through the valve are fed in parallel with pressure medium in separate ducts with the same pressure in the two ducts and in which one of the outputs from the two ducts of the valve retains the same pressure medium pressure even when the position of the valve is changed without any pressure drop occurring during the change. This is achieved by means of a change procedure which is accurately regulated in terms of position. Fig. 1. <IMAGE>

Title: Air aupplying device for engine cooling system of self-propelled agricultural machines
Inventor: KUNZE DIETER
IPC: B60K13/02
Filed: 1977-12-30
Abstract: A cooling system for the power plant of a self-propelled forage harvester or field chopper, generally located in the rear thereof, comprises an air chamber communicating with the atmosphere through laterally disposed filter screens and water-cooling radiators and through pairs of conical half-shells disposed point-symmetrically about ventilating fans integral with a unidirectionally rotatable shaft extending longitudinally in an opening in the top wall of the chamber. The shells, rigid with a support manually pivotable about the power-plant-driven shaft, normally direct air flow through the fans from the air chamber but may be rotated 180 DEG  by a vehicle operator to temporarily reverse the air flow and pressurize the chamber, thus forcing air out through the radiators and filter screens, cleaning them of clogging debris collected during normal operation of the vehicle. Sealer strips provided around the openings in the air chamber for minimizing leakage.
