Patent SE-7704909-L (SE)
Inventor: SISK F J
IPC: H02K9/00
Filed: 1977-04-28
Abstract: A compressor unit for use with a heat pump system wherein a motor-driven compressor is disposed within a casing which can be placed indoors or outdoors. Vapor from the suction side of the system is directed into and through the compressor, through an oil separator-muffler, and then into contact with liquid from the high side of the system, the liquid being directed onto a rotating disk to form a spray which contacts and thereby de-superheats the compressor discharge vapor. The de-superheated vapor then moves into and through the air gaps of the compressor motor in heat exchange relationship thereto where it is re-superheated. The re-superheated vapor then leaves the fan ports of the motor and enters the open top of a vertical standpipe which also receives the excess liquid collected in a trough surrounding the upper end bell of the motor. The liquid is entrained in the re-superheated vapor and moves therewith out of the casing toward the four-way valve and the condenser coil of the system.

Abstract: A non-reciprocal signal path for RF over a broadband frequency range is provided by an isolator comprising two coils or meshes positioned at 90 DEG  to each other adjacent at least one gyromagnetic or ferrite disc which is magnetically biased by a static magnetic field. Each coil is tuned by a parallel capacitor, each coil and capacitor having one end grounded to a surrounding electromagnetic shield. A resistive unilateralizing element is coupled between the input and output terminals and, being essentially non-reactive, provides the broadband characteristic. The energy from the reverse direction is dissipated externally in the resistive element. A magnetic return path of a high permeability material allows the use of smaller biasing magnets and reduces the effects of external magnetic fields.

Abstract: A pumping system for dispensing controlled and variable amounts of fluids in predetermined quantities includes a pump piston which moves axially in a pump chamber. The piston is reciprocated by a drive lead nut cooperating with a non-rotatable lead screw attached to the piston. The piston is sealed to the pump chamber by a seal element whose distance from the lead nut is fixed regardless of the position of the piston, thus protecting the seal. The rotatably driven lead nut includes a hollow driven shaft, containing lubricant, so that the lead screw is lubricated as it travels into the shaft of the lead nut. The motor for the system is a pulse operated reversible stepping motor enabling accurate output from the pump, for example, between .01 ml/min to 9.99 ml/min as controlled by the stepping motor. One motor may drive two pumps for a continuous controlled pumping system. If desired a flush mechanism may be used to rinse the piston of any pumped material which adheres to the surface.

Abstract: Native immunoglobulin is treated, for the selective cleavage of the disulphide bonds between chains, with a sulphite ion in the presence, as oxidising agent, of a compound which is capable of forming a persulphate ion in water. In contrast to the use of oxidising agents which are generally known per se and which give agglutinated immunoglobulin derivatives of increased anticomplementary activity, the immunoglobulin derivatives obtained by this process have reduced anticomplementary activity, can be intravenously injected and are reconverted, within the body of the patient and without side effects, into the original immunoglobulin. By contrast with the known use of alkali metal tetrathionates, iodosobenzoic acid and alkali metal salts thereof, a copper(II) ion or molecular oxygen, the oxidising agents which can be used are industrially prepared, readily available and inexpensive compounds which lead, in a simple manner, to an end product of high purity which can be used without causing any unwanted side effects.

Abstract: In front of the delay connection (T) in the memory circuit is connected a primary mixer (BL1) which mixes the circulating signal with that froma0from a frequency-modulated local oscillator (L0). A band pass filter (BP2) allows passage only to the required mixture result, and a summator (D3) partly couples the mixture result, partly the local oscillator signal to the delay connection (T). Behind the delay connection is connected an effect distributor (D4) with two outlets, and behind each outlet is a band pass filter (BP3, PB4). One of the two band pass filters (BP3) allows passage to the circulating signal, and the other BP4) to the local oscillator signal. A secondary mixer (BP1) mixes the two signals, and a band pass filter only permits passage to the required mixture result, i.e. a signal of the original frequency.

Abstract: A band-tensioning device is disclosed which includes an operating lever rotationally fast with an eccentric which is pivotable about a fixed axis. An angle lever is provided which is freely pivotable about the eccentric, and urgeable to rotate therewith by means of the operating lever. A lower portion of the angle lever has an abutment surface which can cooperate with the friction surface of a rotatable tensioning wheel to force a band to be tensioned against the rotating wheel. The pivoting of the eccentric relative to the angle lever displaces it transversely to the abutment surface, so that the surfaces become separated and thus disengaged without having to overcome the high wedging forces associated with the tensioned band between the surfaces. The levers may be coupled by means other than the eccentric, e.g., via an articulated lever, provided the angle lever is selectively movable pivotally or transversely to the abutment surface.

Abstract: The invention provides a system for the detection of leaks in the primary barrier (150), the secondary barrier (130), and the inner hull (110) of the primary and secondary insulation spaces (140 and 120) of a cryogenic cargo tank (10) carrying liquified natural gas in a transport ship (20) wherein an inert gas is maintained at a first predetermined pressure (PNP) in the primary insulation space (140) which is less than the pressure of the cargo gas (PCH2) and wherein the inert gas is maintained at a second predetermined pressure (PNS) in the secondary insulation space (120) so that the second predetermined pressure (PS) is less than the first predetermined pressure (PNP) and is also less than atmospheric pressure (PO). A gas sensor (930) is placed in the primary insulation space (140) to detect any leaks in the primary barrier (150) and a sensor (940) is placed in the secondary insulation space (120) to detect the presence of any oxygen due to a leak in the hull (110). The flow of the inert gas into and out from both the primary and secondary spaces (140 and 120) over a period of time is measured and any differences in the flow rates in and the flow rates out of each of the insulation spaces is detected. Any differences in the flow rates is indicative of a leak occurring in the secondary barrier and is further indicative of the size of the leak.

Abstract: The effects of vertical perturbations of a gramophone disc record surface resulting from e.g. record warp and rumble are reduced by sensing the perturbations and compensating therefor by closed loop or open loop means. Thus a reference path adjacent the groove tracked by the main stylus may be tracked, e.g. by a supplementary stylus riding on the lands of the disc surface or photoelectrically. A reference path signal may then be derived by a reference path sensor 104, and this signal is then applied to a preferably closed loop servo 95, 98, 100, 112, 114, 97 which moves the disc 9 itself up and down to tend to null out the reference path signal. Alternatively the compensation is applied by causing the tone arm to track the reference path by a servo technique or by mechanical coupling within the cartridge or electrically by subtracting the reference path signal from the main stylus signal, or by a combination of such techniques. <IMAGE>
