Patent SE-7510769-L (SE)
Inventor: DROEGE SR A J
IPC: F04B39/06
Filed: 1975-09-25
Abstract: The invention provides an air compressor of low cost, high quality, long life and of simple and rugged construction and ready replaceability of the chief wear parts as a unit. The compressor employs a wobble piston with a Teflon or equivalent packing on the wobble piston, which packing bears against the surface of a working cylinder of aluminum with a hardened polished surface. The working cylinder in the form of a cylindrical sleeve is seated at its lower end on a circular shoulder in the main housing or frame. At its upper end it is seated and sealed in a groove in a head plate which provides a cylinder head for the cylinder and a closure for the top of the main frame. An inverted cup shaped delivery chamber rests upon and is secured to and sealed by an O-ring of heat resistant rubber to the head plate to receive the delivery of compressed gas and to provide anchorage for a delivery pipe or pipes. The discharge check valve of flanged duck bill formation is held in place by pressure fit of a metal ring in an annular recess, which ring engages and retains the flange of the discharge valve. The Teflon cup leather is clamped to the end of the combined piston and connecting rod by press fitting a ring of metal upon the cylindrical end of said piston, and heat is dissipated from the compressed gas through contact with metal parts which communicate directly, conductively, with outside air and/or radiation cooled surfaces. The Teflon cup and polished cylinder are self-lubricating; the crank shaft and crank pin are self-lubricating by the use of either oil impregnated bushings or by the use of ball bearings; efficiency of compression is aided by the provision of minimum clearances between the piston, the cylinder head, and the discharge check valve. The structure disclosed herein permits of replacement of the working parts consisting of the head plate with a sealing O-ring, and an affixed cylinder with a discharge check valve along with the wobble piston and rod, all assembled as a unit.

Abstract: The invention relates to a method for preparation of perfectly spherical particles of silicagel with controlled particle size and controlled pore diameter, which are suitable as packings for high-speed liquid chromatography and gel permeation chromatography. Free liquid silicic acid is obtained by acidifying of solutions of alkaline metal silicates in organic solvents by organic acids miscible with water in the presence of higher amine as an emulsifier and polymerized to hydrogel in the form of spherical particles. These are isolated and partially hardened by heating above 100 DEG  C in a neutral organic medium, e.g. amyl acetate or dibutyl sebacate, to remove a part of water by distillation, then subjected to hydrothermal processing with water under pressure at a temperature above 150 DEG  C and eventually stabilized. Chromatographic beds of silicagel particles prepared in this way may be used both with aqueous and organic eluants and exhibit very low spreading of zones and high separation efficiency comparable with commercial styrene-divinyl-benzene gels.

Abstract: An intermediate steam superheater includes a heat exchanger comprising a bundle of tubes supplied with steam and subject to the disadvantage that the steam may condense completely in some of the tubes while passing freely through others of the tubes with a consequent loss of heating efficiency. This is corrected by sucking the steam from the outlet ends of the tubes and injecting it into the inlet ends of the tubes so that such a high flow rate occurs through the tubes that the tubes are kept substantially free from condensate while the steam is continuously recirculated through all of the tubes, the condensate from the condensed portion of the steam being discharged from the heat exchanger.

Abstract: ANGULAR COMPRESSION EXPANSION CYLINDER WITH RADIAL PISTONS. An angular cylinder piston combination for providing compression and expansion chambers in a large number of items, such as compressors, pumps, internal and external combustion engines, hydrostatic generators, air motors, and the like, in which compression and expansion chambers are formed angularly, inside a cylindrical drum which rotates at substantially uniform velocity "Wo". The chambers are formed between N outer radial pistons provided by the drum and N inner radial pistons attached to an inner rotor which accelerates and decelerates from zero velocity to a velocity "2wo" with respect to a stationary housing. A single port per chamber provides intake and exhaust as it comes in coincidence with slots, azimouthally cut on the base of the stationary housing. The inner radial pistons, oscillating within the angle subtended between the outer pistons, do not cross the ports; lubricating oil can then be permitted to run between a pair of sealing elements positioned along those edges of the pistons which slide with respect to other members of the device. The application of this angular cylinder in the desing of an improved Tri-Rotor device is demonstrated.

Abstract: A movable motor box for outboard engines designed for deployment at the stern (3) on boats (6) and to carry outboard motors (5).The invention concerns a movable motor box for an outboard engine which is designed so that a part (1) of the motor box is fastened to the stern (3) and a movable part (2), which supports the outboard motor, is then deployed at the fixed part (1). The two parts (1, 2) are joined to each other via an axle (7) which is deployed at the motor box's upper side.The advantage with this invention is that the motor (5) comes to be placed very close to the stern of the boat (3) because the axle (7) which connects the fixed (1) and movable (2) parts is placed so high that its location corresponds to the motor's (5) upper edge (5a) and in this way reduces the motor's swing radius to almost zero.<IMAGE>

Abstract: A pulse generator (3) is controlled by a temperature sensor (5), which detects the temperature of the medium, in such a way that the output frequency (f3) of the said generator (3) exhibits the same dependence on the temperature of the medium as the square of the speed of sound in the medium. A measuring device (4) which is connected to ultrasonic converters (1; 2) and to the pulse generator (3) generates metering pulses, the frequency (f4) of which corresponds to the product of the output frequency (f3) and the difference in the transit times of the ultrasonic pulses received by the ultrasonic converters (1; 2). The output frequency (f3) is composed of a constant frequency (f1) and a variable frequency (f2) which depends on the temperature of the medium. Failure of the temperature sensor (5) does not interrupt measurement, but merely causes measurements to be somewhat less accurate. <IMAGE>

Abstract: Belt strap-clamping device for safety belts in motor vehicles which has a roll-up device with a belt strap which is rolled-up on a belt drum, and which can be rolled out against a spring-force. The belt from the roll-up device is partially wrapped around a deflection member with an arched deflection surface, hinged around an axis, and arranged after the belt drum. The belt strap works in conjunction with a clamping surface which is fixed in the fitting, such that the deflection member is moved when an increased force is applied, and the belt strap is clamped between the clamping surface and the deflection member. At a normal pulling out of the belt the deflection member is held at a distance from the clamping surface by the force of a spring. The deflection surface is formed by a sleeve-like deflection member, which is during normal operation freely rotatable on an eccentrically supported roller, which can be displaced on a predetermined angular path in relation to a clamping surface. The surface of the deflection member is made so that at an increasing radial force the amount of friction between the belt and this surface also increases. Thereby the deflection member is radially displaced with respect to the roller, which has moved into the blocked position, and makes a positive, frictionally coupled connection with the roller.

Abstract: A method of regulating the power effect in an electric load by pulse width regulation includes the steps of conducting a loading current, driving a load, through a transformer, and permitting such current to bring the transformer to a condition of magnetic saturation. The loading current is further conducted through a control circuit which receives a control current for switching the control circuit to the conductive, or live state from the transformer when the transformer is in the non-magnetically-saturated state. An external signal current of a certain duration is conducted through the transformer so that the control current is generated and the control circuit is switched to the conductive state at a first point in time. The signal current and loading current are conducted through the transformer until magnetic saturation occurs after the passage of a certain time interval, this time interval being shorter than the duration of the signal current. The signal current is of a magnitude which is sufficient to maintain the magnetically saturated state. For governing the power effect in the load, the relationship between the duration of the signal current and the time interval is modified.
