Title: Homogenization of water and reduced crude
IPC: C10G11/18
Filed: 1982-08-16
Abstract: An improved process for economically converting carbo-metallic oils to lighter products. Enhanced catalyst activity is enjoyed through use of a select process to vaporize and atomize the high boiling portion of a carbo-metallic oil feed. The carbo-metallic oil feed is dispersed into droplets having a diameter of at least smaller than 350 microns and preferably 100 microns or less. These small droplets ensure more even coverage of the catalyst surface and decrease diffusion problems. The water utilized for dispersion of the carbo-metallic oil feed is present as a homogenized mixture in fine oil droplets with an average diameter below 1,000 microns. The water is dispersed in the carbo-metallic oil feed through use of a select mixing apparatus and can be dispersed as finer droplet sizes through use of an emulsifying or dispersing agent. The ratio of water to carbo-metallic oil feed ranges from about 0.04 to 0.25 by weight and the concentration of emulsifying agent ranges from 0.01 to 10 wt% based on the weight of water.

Abstract: A high voltage disconnect switch, including a countercontact piece having switch countercontacts and being arranged for connection to a source of high voltage. Resilient pre-contact pieces are insulatingly connected to the countercontact piece and include switch contacts disposed for contacting the switch countercontacts. Movable primary contact pieces are arranged to be movable from a first position of separation from the pre-contact pieces and the countercontact piece to a second position in which the primary contact pieces are in contact with the pre-contact pieces but not with the countercontact piece and to a third position in which the primary contact pieces are in contact with both the pre-contact pieces and the countercontact piece. The pieces are configured and arranged relative to one another so that during the closing of the switch the countercontacts contact the contacts after the primary contact pieces are moved to the second position and before they are moved to the third position, and during the opening of the switch the countercontacts separate from the contacts after the primary contact pieces are moved to the second position and before they are moved to the first position.

Title: Alarm device, in particular for an alarm clock or diary
IPC: G04G13/02
Filed: 1985-01-30
Abstract: An alarm device especially suitable for alarm clocks or timers is described, whose alarm signal can either be interrupted for a certain period of time or shut off by an acoustic signal, for example that formed by the human voice. As a result of its low power consumption, the alarm device according to the invention can also be used in battery-powered devices; when installed in an alarm clock or timer, inexpensive mass production is also made possible by using already existing integrated circuits. The alarm device according to the invention is functional even when the acoustic signal produced by the user is only of very short duration or when the alarm signal is delivered as a continuous tone. Advantageously, the alarm device can also be so designed that it delivers an alarm signal at least for a short time when someone is speaking when the alarm signal is triggered and other noises with frequencies outside the frequency range of fundamental tone of the human voice interrupt or shut off the alarm signal.

Title: Apparatus for hardening sand cores and/or sand moulds with a hardenable binder
IPC: B22C9/12
Filed: 1985-06-12
Abstract: An apparatus for hardening cores and/or molds made of sand with the addition of hardenable binding agents, which are used for casting molded bodies from flowable substances, is described, whereby an amount, predetermined by metering devices controlled via control valves, of the substance which causes the binding agent to harden is introduced into the core or mold by aid of compressed air the rate of flow of which is regulatable by a regulating valve, whereby this substance is mixed with this compressed air, and the regulating valve is automatically controlled according to a predetermined schedule. The apparatus can be carried out with considerably fewer components and the necessary control means can in particular be designed much more simply if, according to one embodiment, the regulating valve is controlled by means of a proportional pressure regulating valve which is operated by an external control means which also controls the other control valves. As an alternative to this, the regulating valve can be controlled, according to a second embodiment, via a preadjustable pressure regulating valve and a directional valve which is controlled electrically or pneumatically.

Title: Blood pump
IPC: A61M60/876
Filed: 1985-03-22
Abstract: A blood pump comprises an atrium chamber defined by flexible walls and having an inlet and an outlet, a ventricle chamber defined by flexible walls and having an inlet and an outlet, a passage communicating the outlet of the atrium chamber with the inlet of the ventricle chamber, a first one-way valve in the passage adapted to permit blood flow only from the atrium chamber to the ventricle chamber, and a second one-way valve in the outlet from the ventricle chamber adapted to permit blood to flow through the outlet only out of the ventricle chamber. The chambers are movably supported in a casing having first and second openings, the atrium chamber inlet being fastened to the first opening and the ventricle chamber outlet to the second opening. A drive device cyclically moves the walls of the ventricle chamber to decrease its volume and expel blood from it while simultaneously moving the walls of the atrium chamber such that its volume may increase upon inflow of blood into the inlet to it. The drive device includes a drive ring surrounding and joined to the passage and having a surface engageable with the walls. of the ventricle chamber over a selected area such that the pressure of blood entering the chambers between driven strokes of the drive device controls the output of the blood pump by establishing the magnitude of the return stroke of the drive ring as a function of a pressure force acting over the area of engagement between the drive ring and the walls of the ventricle chamber.

Patent EP-0231609-A3 (EP)
IPC: G01N27/06
Filed: 1986-11-27
Abstract: A multiple electrode conductivity sensor generates an 
output to be applied to a special temperature compensation 
system that responds to a temperature sensor signal indica­
tive of the sample water temperature. The temperature signal 
selectively operates a memory unit that contains separate 
water and salt correction values to be used in adjusting the 
measured conductivity output. The water correction value re­
presents the conductivity of absolutely pure water at the 
measured temperature, and this value can be subtracted 
from the measured total conductivity to produce a con­
ductivity value attributable only to salt impurities. The salt 
correction signal from the memory unit is then used to scale 
the measured salt conductivity signal at the standard refer­
ence temperature of 25°C, thereby achieving a corrected salt 
conductivity measurement that can be added to a fixed pure 
water correction signal representative of the conductivity of 
pure water at that temperature. The sum of these values 
yields an adjusted output signal that accurately reflects the 
conductivity (or resistivity) of the pure water solution at the 
standard 25°C temperature. To avoid inaccuracies due to el­
ectrode deposits, the excitation voltage applied across the 
current electrodes of a four electrode conductivity sensor is 
monitored to produce a warning whenever the sensor circu­
itry nears the limit of its ability to overcome the effect of ac­
cumulated deposits, thus alerting the operator to the need for 
cleaning the electrodes before substantial inaccuracies can 
occur.
