Abstract: TWO-PART, TWO-TIER CURE            ADHESIVE COMPOSITION     ABSTRACT OF THE DISCLOSURE     A two-part composition comprising as a first part a polymerizable vinyl-type material and a free-radical polymerization system comprising at least one aromatic acyl peroxide and a compound selected from the group consisting of peroxides, hydroperoxides, peresters, persalts and peracids, exclusive of aromatic acyl peroxides; and as a second part a polymerizable vinyl-type material and an accelerator system comprising an amine and optionally either a sulfimide, an hydrazine derivative, or both.  The resin systems of each part are substantially similar in rheology and viscosity to optimize the effectiveness of the adhesive composition.  The composition combines anaerobic-type cure systems to obtain excellent cure through volume (CTV).  The non-anaerobic-type cure system allows for the superior CTV capability over the prior art and is not dependent on metal ion catalysis for cure accleration, making the composition particularly useful on inactive surfaces such as plastics or aluminum.

Abstract: ABSTRACT OF THE DISCLOSURE A device for tethering an animal comprises a suspension element and a multipart yoke with two top parts which are hingedly suspended from the suspension element. Each top part comprises a projection.  Springs push the end of each projection away from the top part bearing the other projection, thus bringing the top parts into an open position or a closed position.  A lever mounted relative to the suspension element brings the top parts from the closed position to the open position.  The lever bears a spacer member which, in the closed position, is present between and against the top ends and which in the open position does not engage the top ends.

Abstract: METHOD FOR CLEANING INTERNAL HEAT SURFACES                 OF POWER GENERATING EQUIPMENT                   ABSTRACT OF THE DISCLOSURE    A method for cleaning internal heat surfaces of power generating equipment, which consists in purging power gene-rating equipment with superheated steam and oxygen driven at a speed of 20 to 80 m/sec. The oxygen consumption is 0.3 to 1.0 kg per ton of steam. The process both cleans and passivates internal heat surfaces of power generating equipment.    The method considerably facilitates the cleaning of internal heat surfaces of power generating equipment, be-cause it dispenses with chemically aggressive reagents and effluent purification installations. It is further advan-tageous in that internal heat surfaces of power generating equipment are both cleaned and passivated.

Abstract: ABSTRACT OF THE DISCLOSURE            Herein disclosed is a lance structure for use with a top-blown converter.  The lance structure is constructed to include a cylindrical sheath having a bottom wall and a flux supply tube disposed at the center of the sheath and defining a passage for carrying slag-forming flux in a powdered form.  Further inclusive is an oxygen supply tube which is arranged in the sheath and around the flux supply tube and which defines an annular oxygen supply passage.  From the oxygen supply tube, there lead a number of Laval nozzles which have their exits opened in the sheath bottom so that the oxygen gas supplied through the oxygen supply passage may be blown in the form of supersonic jets to penetrate into the molten iron contained in the converter.  The flux supply tube is formed with ports which are opened into the Laval nozzles just upstream of the exits thereof to feed the flux together with a carrier gas to the supersonic oxygen jets so that the carrier gas flows may merge into the oxygen jets.          Thus, the powdered flux can be uniformly dispersed in the oxygen jets without wearing and damaging the inner walls of the Laval nozzles and can be carried by the jets deeply into the molten iron.

Abstract: ABSTRACT SHEET MATERIAL A method of making a large elongate discontinuous sheet comprises: (i)   providing a plurality of vulcanizable rubber sheets the bonding edges of which comprise complementary formations, (ii)  overlapping said bonding edges by engaging said complementary formations, the thickness of the resulting overlap (27) being substantially equal to that of the surrounding sheet, and (iii) subjecting the assembly to conditions which will vulcanize the assembly and bond the overlapped edges.       The join or joins 27 are preferably longitudinal of the sheet and are achieved without the need for an adhesive.  The main advantage of the method is that it results in a sheet without enlarged seams i.e. a better looking product with fewer handling difficulties.  Uses of the sheet product include roofing and tank lining.       Also described is an apparatus for making the sheet material which comprises carrier means for receiving a plurality of sheets and supply means for feeding the sheets to said carrier means so that adjacent sheets overlap.

Abstract: ABSTRACT OF THE INVENTION         In a charge-coupled device, a DC bias on its signal  register  input  is  automatically  corrected  for thermal  fluctuations  and other  environmental effects.          First and second reference registers are deposited on the same substrate as the signal register.   The first register has the same input structure and control as the signal register and the same output end as the second reference  register.   The  input channel width of the second register is selected such that the ratio of the input widths of the first and second reference registers matches the ratio of the dynamic range and desired bias level of the signal register.   All three registers are clocked  synchronously,  but  the  input  of  the  second register  is  saturated  while  the  other  registers  are biassed to the same degree.  The output charges of the two   reference   registers   are   compared   and   their difference  is  fed  back  to  the  inputs  to the  signal register and first reference register to adjust the bias level.
