Abstract: A process for the manufacture of a composite oxide comprises carrying out, in a non-aqueous medium, a condensation reaction between an organometallic compound having a structure such that the metallic element present in the compound is bonded to the organic moiety therein via an oxygen atom, and a protic acid which is capable of carrying out the condensation reaction with the organometallic compound, and is a hydroxide containing an element different from the metallic element contained in the organometallic compound. The composite oxide can be produced with a high level of purity but without segregation.

Abstract: A programable controller is provided which includes a cycle time setter, a counter, and a calculator. The cycle time setter sets a cycle time for one round of execution of a sequential series of processing routines. The counter counts an execution time between the start of a first predetermined processing routine of the series and the termination of a second predetermined processing routine of the series subsequent to the first. The time difference between the execution time counted by the counter and the cycle time is calculated and, if positive, is allocated to execution of the remainder of the processing routines in the series.

Abstract: A method for temperature control of the heating medium of a closed loop heating system operated with a burner envisages that this control is carried out depending upon both the actual temperature of the heating medium and the outside temperature, and more particularly both by control of the burner capacity and by control of the circulating speed of the heating medium, the control of the circulating speed of the heating medium being started preferably only when a predetermined minimum temperature of the heating medium is reached. A device which is suitable for implementing the method comprises a control (6), to which are connected both an outside temperature sensor (7) and a temperature sensor (12) arranged in the forward run (10) of the closed loop heating system (10, 11), and which can control both the fuel supply to the burner (1) of the heat exchanger (2) via a fuel supply valve (3) and also the speed of the circulating pump (9) depending upon the temperatures measured.

Filed: 1988-10-18
Abstract: The edges of address elements such as address labels and window apertures located on a mailpiece, are detected by utilizing illumination from first and second alternating "on" and "off" light sources which illuminate the address elements at an acute angle. In the case of label detection, the edge closest to the on illuminating source generates a high contrast image, while the edge furthest from the "on" illuminating source is shadowed. In the case of illumination of an aperture, the opposite is true. That is, the light reflected from the edge which is furthest from illuminating source is high contrast, while edge closest to the illuminating source has a lower contrast. When the images generated due to edge illumination by the left and right light sources are subtracted from each other, the edges are further enhanced due to the fact that the remaining portions of the images cancel each other out.

Abstract: The invention relates to an arrangement for accommodating livestock, in particular pigs, in which the animals are accommodated individually, or several together, in sleeping boxes so that they can only lie side by side and primarily only in one direction, or in some cases also in opposite directions. The arrangement can have air intake, air circulation and/or waste air devices by which the air is treated in accordance with the animals' requirements. An essential feature is that an aperture (4) is provided on at least one side (3) of the sleeping box through which the animal can on its own initiative move its head into a region outside the sleeping box. The aperture (4) is provided with a single or multiple curtain (5). The device has the advantage that the warmer region surrounding the body of the animal is formed separately from the head and respiration region, and that the air conditions in these regions can be separately adjusted.

Abstract: Methods are disclosed for conducting assays. One such method comprises providing in combination a first bibulous member zone ("first zone") and a liquid medium containing a component. The first zone has non-diffusively bound thereto a reagent interreactive with the component. Conditions are selected wherein the liquid medium and at least a portion of the component contained therein traverse all of the first zone and migrate into a second bibulous member zone ("second zone") of a different composition than the first zone by capillary migration. The distance the component has migrated into the second zone or the difference in the distances the medium and the component have migrated into the second zone is determined, the distance or the difference being related to the amount of the component in the liquid medium or the amount of the reagent. Another such method comprises causing a specific binding pair member in a first liquid medium to become bound to a first bibulous member by contacting a portion of the first bibulous member with the medium. The first bibulous member is in liquid receiving relationship with an absorbent member. The contacting is carried out under conditions wherein the first medium traverses the first bibulous member and at least a portion of the absorbent member by capillary action. The method further comprises causing the first bibulous member to come into liquid receiving relationship with a second bibulous member. A component in a second liquid medium is transported to and preferably becomes non-diffusively bound to the second bibulous member in relation to the presence of analyte in   the first medium. This is accomplished by contacting a portion of the first bibulous member with the second medium under conditions wherein the second medium traverses the first bibulous member by capillary action and at least a portion of the second bibulous member. Next, the presence of the component on at least a portion of the second bibulous member is determined.

Abstract: An electrical connector for connecting a first conductor to a second conductor. The electrical connector includes a generally E-shaped body which defines first and second conductor receiving cavities for accommodating the respective conductors. An intermediate member extends generally centrally in the interior of the body member, serving to separate the conductor receiving cavities. The body member is provided with an opening communicating with the conductor receiving cavities, by means of which the conductors are adapted to be positioned within the cavities. A plurality of rib members project from the body member into each of the cavities, and are deformable under pressure to vary the size of the cavities. An integral retaining member is associated with the intermediate member, being connected thereto by means of a two-way hinge, whereby, when a conductor has been placed in either one of the conductor receiving cavities, the retaining member may be manually rotated to a position wherein it encloses and secures the conductor in the cavity. The connector is then intended to be placed over a second conductor, such that the second conductor is received in the other conductor receiving cavity. The connector is adapted to be compressed, by means of a compression tool, so as to substantially close the opening in the body member. The retaining member extends from the hinge, through the opening, and terminates in an end situated beyond the upper and lower arms exteriorly of the body member. The retaining member is thus able to be manually grasped by the installer at the exterior of the body member.
