Abstract: A pin plug comprises an inner contact member in the form of a pin made of metal, an outer contact member in the form of a cylindrical metal body and an insulating member for fixing the inner and outer contact members in position in an electrically insulating manner. Said insulating member comprises an inner insulating member consisting of two semi-cylindrical halves which form in a joined condition a hollow cylindrical space in which said inner contact pin is fit. The insulating member further comprises an outer insulating member or cover made of relatively resilient material. The outer contact member consists of two semi-cylindrical halves which are fixed around the outer surface of the inner insulating member. The assembly of the inner contact pin, the inner insulating member surrounding the pin and the outer contact member surrounding the inner insulating member is resiliently inserted into the space of the outer insulating cover.

Abstract: A procedure is described for supplying thermal energy to a steel melt by burning a fuel in a melt containing at most 0.10% carbon, by means of oxygen. Both the fuel and the oxygen are introduced into the steel melt beneath the surface of the melt. The method permits an increase in the scrap or other iron carriers, (ore, pellets, etc.) which can be processed. Apparatus for carrying out the process is also described.

Abstract: A portable carrier for one or more beverage cans or bottles, the carrier being made of a lightweight insulating material such as a foamed synthetic resin which retains the cold (or heat) of the contents of the container. The resin is molded with pocket(s) to receive the beverage containers and is provided with attachment means to which a strap can be attached so that the article carrier can be worn either on a belt carried by a shoulder strap in order to permit the user to withdraw a can or bottle by the use of only one hand. A preferred attachment means includes a harness which is shaped to receive the article carrier and to articulate with a cover on the carrier.

Abstract: A helmet for use in riding vehicles such as motorcycles, motorbikes, etc. comprises a cap like body made of hard material, a bumping body applied on an inner surface of the cap like body, a number of streamline recesses formed in the bumping body and extending from a forehead portion to a backhead or side portion of the cap like body. When a user wears the helmet, the air stream flows through the recesses from the front openings to the rear openings of the recesses and thus the temperature and humidity inside the helmet are decreased.

Abstract: A device is provided for a meter having an indicator, e.g. a pointer, and which detects the presence or absence of the meter pointer at one or more set points or between two set points. The device does not alter the operation of the meter and may be coupled to an alarm or other signal, or it may be used to actuate a mechanism under control of the meter. The device comprises at least one light-emitting diode which produces radiation which falls on a specific area of the meter face and on the meter pointer (if it is within that area) and is reflected from the meter face (and the pointer) to a phototransistor or other suitable receiver which "reads" the signal produced by the radiation reflected from the meter face and the pointer, if present in the area read. The device is mounted so that it can be moved to any desired area of the meter face. Preferably the device is mounted externally to the meter. However, it may be enclosed within the usual meter housing, without altering the operation of the meter.

Abstract: A method of drilling a large hole through rock and removing the drilling waste by drilling a pilot hole from one rock face to another, reverse drilling with a large drill bit and removing the waste during the reverse drilling by pressurizing the pilot hole to eject the waste through a muck extractor dragged behind the large drill bit; and an apparatus to carry out this method consisting of a sealing member for the one rock face, and a muck extractor for securement to the large drill bit.

Abstract: A bushing for use with an underground storage tank, consisting of a wall having inner and outer screw threads, the outer thread being a standard taper of 1.degree. 47' and the inner thread being a non-standard taper of between 1.degree. - 48' and 16.degree. - 47'.

Abstract: A method for producing steels within a very close analysis tolerance in which the raw materials are melted down in a first vessel, the melt is then tapped into a second vessel in which deslagging is accomplished, and thereafter the melt is subjected to treatment under a vacuum. An apparatus for carrying out the method is also described.

Abstract: A rapid method for assaying collagen in meat and meat products. A sample of the material being tested is subjected to a controlled, incomplete hydrolysis of the amino acids with an acidified solution of stannous chloride in such a way that all of the tryptophan is completely destroyed but only a portion of the hydroxyproline is hydrolyzed. The percent collagen is correlated with the percent hydroxyproline, colorimetrically determined.

Abstract: A method and apparatus for monitoring the buildup of fog in a non-silver free radical film while a latent image in said film is being optically developed, wherein the buildup of fog is sensed by radiation directed at a non-image area of said film and reflected from said area to a sensing device. The reflected radiation is altered as the buildup of fog takes place.

Abstract: An electrostatic aperture printer employing a gating mask placed between a source of ions and a charge receiving member to generate imagery consisting of aggregations of elemental dots or line segments formed in response to electronic control signals wherein the improvement lies in electrically biasing the mask or mask segments in such a way that the functions of ion collection and control are combined in the region between the mask and a charge receptor backing electrode via the establishment of appropriate transmission or blocking fields. Further electrostatic printing improvements incorporated are the development of useful charge receptor holddown forces via static or rolling backing electrode structures designed to make constructive use of the longitudinal tension normally developed in receptor web handling, and enhanced ion transmission achieved by means of shaped aplanar mask structures incorporating zones fabricated from insulating material.

Abstract: A carrier is disclosed for diagnostic scanning agents labelled with short-lived radioisotopes for medical organ studies which comprises colloidally dispersed phospholipid material, and also disclosed are new diagnostic scanning agents utilizing the carrier and a radioisotope, preferably .sup.99m Tc, which is in a form which complexes with the carrier. The radioisotope labelling can be carried out directly before use, the carrier in dispersed form being stable for a considerable period of time. Methods of preparation of the scanning agents are also disclosed which provide a material which localizes mainly in the liver after injection, or alternately at least initially in the lungs when an aggregating agent is used during preparation in a specific sequence of steps. Specific organ scans or sequential scanning is thus possible.
