Abstract: COATED FOOD PRODUCT AND METHOD          OF MAKING SAME               Abstract of the Disclosure The food product of this invention is produced by applying an aqueous dispersion containing water soluble algin to the surface of a food substrate.  The aqueous dispersion has a viscosity effective to substantially uniformly coat the surface of the food substrate.  A dry gelling mixture is then applied to the algin-coated food substrate for a period of time sufficient to form a substantially continuous edible alginate film along the surface of the food substrate.  The film is sufficient to effectively retard the migration of moisture from the surface of the food substrate thereby retarding dehydration thereof.  The film is sufficient to constitute an oxygen barrier for retarding oxidation of the food substrate and to retain flavor within said food sub-strate.  The dry gelling mixture comprises a dry carrier material and a dry gelling agent.  The carrier material and gelling agent are in particulate form and have particle sizes sufficient to obtain a substantially uniform gelling mixture.

Abstract: Abstract:    A method is described for quantitatively determining the different forms of sulphur present in a sample of material, such as coal.  The sulphur-containing sample is burned in finely divided form within a confined combustion chamber at a predetermined elevated temperature.  Combust-ion gases are continuously removed from the chamber and these pass through an infrared analyzer which continuously monitors the intensity of the infrared spectra for sulphur dioxide in the combustion gases.  The infrared intensity is measured as a function of combustion time of the sample to obtain peaks in the infrared intensity-time pattern indicative of different forms of sulphur.  From these pattern peaks the quantity of each form of sulphur in the sample is determined.

Abstract: Abstract of the Disclosure:       In a TDMA satellite communication network compris-ing a plurality of earth stations, a predetermined one of the stations is operable as a primary reference station for producing a first and a second reference burst to define a multiframe and a frame in an up-link signal, respectively.  A synchronization burst is placed at every multiframe by each station with reference to the first and the second reference bursts detected from a down-link signal.  A subsidiary reference station is selected from the remaining station to produce a specific one (SY2) of the synchronization bursts and a subsidiary reference burst (SR1) which is placed at the same time instant as the first and the second reference bursts.  When the first and the second reference bursts disappear from the down-link signal, each station keeps synchronization with reference to the specific synchroniza-tion burst.  Thereafter, synchronization is kept in each station with reference to the subsidiary reference station.  The subsidiary reference burst may be produced in place of and simultaneously with the first and the second reference bursts when a single carrier frequency and a plurality of carrier frequencies are used in the network, respectively.  Use of the plurality of carrier frequencies requires partial modification of hopping operation.  The partial modification is possible by selectively producing a modification hopping code represent-ative of modification of the hopping operation.

Abstract: ABSTRACT OF THE DISCLOSURE         A valve actuating mechanism for an overhead valve and overhead cam type internal combustion engine in which the camshaft is positioned above and between the valve and a cam follower seat member in the cylinder head.  The cam follower has downwardly facing portions on each end for engaging the valve and seat member and an upwardly facing slipper face for engaging the cam on the camshaft for causing rocking or pivoting motion of the cam follower.  The shape of the slipper face is formed to engage the cam at the start of the valve-lifting movement of the cam follower to minimize the lateral forces on the cam follower which otherwise would tend to cause shifting of the cam follower and resultant noise and wear.  Alternatively, the shape of the slipper face may be formed to engage the cam at the start of the valve-lifting movement of the cam follower to produce a resultant force on the cam follower which compensates for frictional force between the cam and the slipper face and does not include a component of force tending to laterally shift the cam follower.

Abstract: ABSTRACT OF THE DISCLOSURE A light diffusive coating having an excellent light diffusion effect, a method of forming the coating and a halogen lamp with the coating.  The light diffusive coating includes bubbles within a continuous coating consisting of a metal oxide formed on a base.  The method of forming the light diffusive coating is made by the inclusion of bubbles formed by the evaporization of a high boiling-point organic solvent within the metal oxide coating formed by the application of a combination of an organo-metallic compound with a high boilig-point organic solvent to a base surface, and the subsequent decomposition of the organo-metallic compound on baking.  The halogen lamp has a porous light diffusive coating formed on the coating estblished on the surface of the outer vessel which allows visible light to pass through but reflects infra-red light, so that strain, caused by the difference in thermal expansion efficient of the structural material of the outer vessel and the structural material of the light diffusive layer occuring when the outer vessel is at a high temperature, is absorbed by the porous structure, and prevents peeling.
