Patent SE-8106475-L (SE)
Inventor: MITCHELL A I S
IPC: F04B25/02
Filed: 1981-11-03
Abstract: A preferably two-stage gas compressor (1) is described which has two opposing cylinders (31, 41), in which pistons (30 and 40), which are fixed at the ends of a spindle (20), are displaceable forwards and backwards. The spindle (20) is carried in an axial direction through a spindle nut (14), which is part of the rotor of an electric motor (16). The electric motor (16) (preferably an alternating current motor) drives the pistons (30 and 40) in their reciprocating movement to the stop on the associated cylinder head (32 and 42), which is determined by a control unit which thereupon reverses the running direction of the motor (16). Owing to the output characteristic of alternating current motors, the compressor (1) functions relatively slowly and - also due to low chamber residual volumes - achieves high compression ratios without contaminating the gas with constituents of the lubricant, because self-lubricating piston seals can be used. <IMAGE>

IPC: F02P11/02

Abstract: Ignition pulses derived from an engine ignition coil primary are fed to the input of an ignition interruption circuit that employs an integrated circuit timer. The state of the output terminal of the timer is governed by an RC time constant circuit and by trigger signals supplied by a trigger circuit in response to occurrence of each ignition pulse. The timer output is coupled to the gate of an SCR which when it receives gate current as a result of the timer output being in a high state becomes conductive and bypasses ignition pulses to ground to thereby lower engine rpm to a preset minimum in which case gate current is removed and at least enough ignition pulses are allowed to be unbypassed for keeping the engine running above stalling speed. The timer, in effect, compares the interval between pulses with its time constant. When the intervals are longer than the time constant period the timer output remains low and provides no gate current, but when the opposite condition exists gate current is supplied until the intervals between ignition pulses equal or exceed the time constant period.

Abstract: Side walls (9, 10) extend to the vicinity of a top side of a pipe. Evenly spaced plugs (2) are inserted in the bottom of the pipe and grip the pipe at the lower end of a rise space. At the upper end is a perforating component (7) which can pass through the top side of the pipe (6). - Under the perforating component is a seal (8). The perforator is pressed through the pipe and then springs backwards and is sealed, with the plugs in position. This ensures that the two halves of the pipe are not pressed against one another and that the rise space does not bend to one side or the other. The plugs prevent water flow in the rise space longitudinal direction, which is essential for the long-time function of the drain pipe. (Dwg.No.2)

IPC: B66C13/46
Filed: 1987-11-26
Abstract: A camera system is installed in the building site crane so that the crane operator can monitor, via a screen, the lifting and handling operations. This can be done in detail so that he can follow the lifting function, and also the ground surface around the point from which the lift is effected. The system is based on a power and picture transmission technique which overcomes all stresses and strains arising from very adverse weather conditions during the lifting operations. The picture reproduction in the operator cab is such that it does not interfere with the physical work of the operator, but ergonomically directed so that visual control of the lifting and connection operations may occur on a continuous basis. It further enables the operator to receive information continuously as to the lift height and wt., and length of the crane outrigger.
