Inventor: OGLE R W
IPC: A61M5/162
Filed: 1980-11-07
Abstract: A transfer device for withdrawal of aliquots from a container of bulk solution is provided with a body having a tapered chamber, a first passage venting the smaller end of the chamber to the surrounding air, a second passage communicating at one end with the larger end of the chamber, and a third passage having one end for withdrawal of fluid therefrom. A tapered valve element is received within the chamber for movement between first and second conditions in response to changes in the presence differential between the first and second passages. The first condition provides a fluid seal between the first and second passages by engagement of the valve element with the walls of the chamber for pressures within the second passage greater than that within the first passage, and the second condition provides a fluid path from the first passage to the second passage for pressures within the second passage somewhat less than that within the first passage. The device further includes structure placing the other ends of the second and third passages in commuication with the interior of the container of bulk solution, such that a path is provided for air to be drawn into the container when aliquots of solution are withdrawn from the container through the third passage.

Abstract: Arrangement for permitting control of the current and/or voltage values connected to the respective electrode groups in an installation (1) comprising several electrostatic dust separators or electrode groups (A, B, C) so that the total current and voltage requirement of the installation can be minimised to give a desired dust loss and where the installation is provided with a unit (15) which evaluates an actual dust loss in the outgoing, cleaned gases, together with a control arrangement appertaining to each electrode group, so arranged that as a function of control signals received it raises or lowers the current and/or voltage values for the associated electrode group. An actuating device (16) common to all electrode groups is arranged so that in an initial time period (t1-t2) it instantaneously changes the prevailing current and/or voltage value for an initial electrode group (A), and after evaluation of a change in the dust loss (dS) in the installation corresponding to the alteration it stores (18) the said change. In a second time period the changed current and/or voltage value is restored to the value prevailing prior to the change. In a third time period (t3-t4) the instantaneous current and/or voltage value is changed for a second electrode group (B) and after evaluation of a change in the installation dust loss which corresponds to the alteration the said change is stored (19). During a fourth time period it restores the changed current and/or voltage value to the value prevailing prior to the change, etc. 
<??>After an evaluation has been made of preferably all the electrode groups (A, B, C), that group or those groups which give a predetermined change in the dust loss in the event of applied change in the current and/or voltage value receive, via the actuating device (16) and a calculation circuit (21) arranged therein, a changed current and/or voltage value (SA-SC) which gives rise to a change ( DELTA S) in the dust loss towards the desired or permitted dust loss.

Abstract: Method and system for amplifying initial electrical energy inputted into a prime mover to produce much higher levels of work output than would ordinarily be possible, by intermittently energizing an electromagnet (2) to develop strong, short-lived repelling magnetic power pulses between it and a similarly polarized permanent magnet (1); using such intermittent repelling magnetic pulses to drive a spring-loaded reciprocating piston (4); and rigging up such piston (4) to pressurize hydraulic fluid for use in a hydraulic motor (30), or to drive an engin crankshaft directly. Alternatively, the invention may be modified by using two electromagnets (Fig. 2, 1 and 2) to develop the necessary magnetic repelling pulses, or to pressurize gas instead of fluid for use as a driving medium in the prime mover.

Abstract: A pipe coupling, particularly for plastic hoses, comprises a sleeve-shaped inner portion (11), which is intended to enter into the end of the pipe (10) to be coupled in order to support the pipe wall (12) on the inside of the pipe, and a sleeve-shaped outer portion (13), which is adapted to surround the pipe end on the outside of the pipe to force the pipe wall (12) towards the inner portion (11), so that the pipe end is clamped between the inner portion (11) and the outer portion (13) of the coupling. The external surface of the inner portion (11) and the internal surface of the outer portion (13) are provided with a plurality of ring-shaped ridges (21, 22), which run around the portions (11, 13) and have a substantially triangular cross section. The ridges (21) of the inner portion (11) are displaced axially in relation to the ridges (22) of the outer portion (13), and the ridges (21, 22) are provided to penetrate only partly into the pipe wall (12), so that a space (m) is formed between the pipe wall (12) and the inner portion (11) and the outer portion (13), respectively, between the ridges (21, 22). Thus, the thermal expansion of the pipe material can occur substantially radially, so that the risk of leakage due to the deformation of the material is eliminated.

The hammer (4) is moved by applying the mains frequency. The microphone (5) is arranged close to the hammer (4), the tapping noise being recorded by said microphone (5). Magnetic strips are provided on the test equipment for guidance. The equipment is mounted on a rod (7) for pushing into the machine air gap.

Abstract: A variable volume ratio screw compressor has a side load inlet port for the injection of refrigerant vapor into the interlobe volume. In order to improve efficiency, overcompression and undercompression are avoided by varying the location of the radial discharge port to give the compressor an internal volume ratio matched to the pressure of the system in which the compressor operates. This is accomplished in the present application by locating a pressure sensing port no earlier than and preferably later in the compression than the side load injection port, but early enough in the compression that it will not communicate with the discharge port. The pressure that is sensed in the sensing port is used to predict the actual peak pressure in order that maximum efficiency may be obtained as a result of matching the internal volume ratio to the pressure ratio of the system.
