Abstract: ABSTRACT OF THE DISCLOSURE: The invention relates to electric incandescent lamps having a gas fill containing halogen. The internal surface of hte lamp envelope and optionally also the exposed surface of internal components of the lamp are protected from attack by halogens including flourine by a continuos imperforate coating composed of a metal oxide resistant to halogen attack. In order to achieve the necessary degree of continuity of hte coating the oxide is formed in situ from a compound of the metal deposited as a solution on the surface. The preferred oxidee is alumina, the other oxides of polyvalent and transition metals, including metals of the lanthanide series may be used. The coatings are preferably formed from solutions of halides of the metals in polar organic solvents such as methanol. The invention prolongs the life of lamps provided with the protective coating and enable such resistant and possibly cheaper materials to be employed for certain lamp components.

Abstract: Abstract of the Disclosure An electrode is provided which is a part of an apparatus for measuring the electrical impedance of a variety of materials for the purpose of determining moisture content.  The electrode is composed of a pair of spaced-apart conductors across which an electric field is radiated so that this electrical field passes through substantially all of the material sample enhancing the accuracy of the impedance measurement.  A number of different embodiments of the electrode are disclosed, each embodiment being particularly sized and shaped for use with a different type of sample material. In a first embodiment, useful for measuring the moisture content of a sample of grain or the like, the electrode is shaped as a box including a flat central electrode plate vertically mounted within and electrically isolated from the enclosing grounded walls of the container.  In a second embodiment, adapted for measuring the moisture content of stacked tissue paper or the like, the electrode includes a pair of opposed plates, both of which are electrically drive by a sensing circuit.  In a third embodiment, particularly suited for the discrete measurement of moisture content in wood chips, the electrode is shaped as a front opening box including a flat central electrode plate mounted on and electrically isolated from a grounded backing plate.  The forward walls of the box holding the wood chips are pivotally mounted at the top of the backing plate so that the lower end of the sample box opens outwardly to ensure complete dumping of the material sample.  In a fourth embodiment, used to measure the moisture content of lumber as it dries in a kiln, the active electrode is shaped as an elongated cylindrical rod which is inserted into the center of the stacked lumber.  Since the walls of the kiln or the rails supporting the loaded car are normally formed from a metallic material, these grounded conductors can be used in conjunction with the central active electrode to measure the impedance variations in the drying lumber.

Abstract: ABSTRACT OF THE DISCLOSURE   A method of manufacture for forming a novel magnetic read/write transducer head of the type utilizing thin film materials.  The method of manufacture comprises steps which deposit a thin film magnetic recording head on a selected substrate having dimensions which enable batch manufacture of a thin film magnetic transducer in combination with its supporting slider assembly. The substrate of selected material in thick wafer form is subjected to a series of thin film deposition, etching and plating operations to form a plurality of thinfilm magnetic heads thereon.  Thereafter, the substrate wafer is diced around each thin film magnetic transducer head with subsequent finishing and polishing to re-quisite shape thereby to yield the complete slider and transducer head assembly.A particular form of thin film magnetic transducer head is further novel in thatthe head utilizes shield and pole pieces that are formed as multi-layer thin film pairs of magnetic material as deposited in order and formation to contain the magnetoresistive stripe and operative elements.  The multi-layer pole de-positions may be further altered as to number of thin film layers and thickness thereof in order to shape the magnetic fields associated therewith, especially as regards the trailing edge or write pole formation.

Title: Method and compositions for the control  of coccidiosis in poultry
Inventor: DAVIS PAUL J
IPC: A23K1/00
Filed: 1978-11-14
Granted: 1981-12-15
Abstract: Abstract Effective immunity against coccidiosis can be imparted to poultry if the birds are reared on a regular diet containing added viable sporulated coccidia oocysts at a level sufficient only to induce sub-clinical infection.   Preferably the oocyst-containing diet is presented to the birds as soon as they are able to ingest solid food, and contains from 10 to 10,000 oocysts per kg of nutrient feed material.   The simultaneous administration of an anti-coccidial drug at a curative level can help to control the immunity-producing infection.   The oocyst-containing feedstuff of the invention can be prepared using solid free-flowing pre-mixes or aqueous concentrates, containing appropriate numbers of oocysts together with edible thickening agents.   The oocysts can be protected against loss of viability through debydration by being encapsulated.          Growth of the immunised birds is sustained even when they are exposed to a severe oocyst challenge sufficient to induce serious infection in unimmunized birds (Fig. 2).
