Abstract: THREE-POINT SUSPENSION DEVICE FOR TRACTORS          ABSTRACT OF THE DISCLOSURE     In  the  case  of   the  adjustable  upper  link  in   a three-point suspension device for  a tractor, comprising a locking  device in the  form of a line fitted  with a shut-off  device  and   connecting  together   the   two end-faces  of  the  hydraulic  cylinder,  the  invention simplifies the  operation of the  device in that  it may be  adjusted effortlessly from the  tractor-seat.   This is achieved in that the shut-off device  is in  the form of a ball-valve  having  an  axis secured  to  a  forked actuating lever,  and in that springs  are  provided  to urge  the  said actuating  lever  towards  the  shut-off position.  A scale provides  the  tractor-driver with an accurate indication of  the  setting  of the  link.  The design  of   a  tube  accommodating  one   end   of  the piston-rod   as   a   compressed-air   chamber   ensures automatic displacement of the  piston  in the  hydraulic cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus for labelling conveyed articles applies glue to the rear surfaces of labels and applies the glued labels to the articles.  The apparatus comprises a device for passing the rear face of the label by a glue applicator and then applying the glued label to an article.  In the absence of a label on the device, the pad for carrying labels is withdrawn as it passes the glue applicator.  The label transferred to a pad is held on its face by the use of vacuum.  When a label maintains vacuum on the pad face, a brake in response to the maintained vacuum is actuated to prevent withdrawal of the pad, as it passes the glue applicator.  In the absence of a label, the brake is inoperative to allow the pad to withdraw and avoid application of glue to the pad face.

Abstract: ABSTRACT        In the carbothermic reduction of alumina evolved carbon monoxide has a high content of Al fume and Al2O.  A substantial part of this fume is recovered by allowing the temperature of the CO gas to fall by 50-150°C during passage through a moving bed of carbon particles at a temperature of 50-150°C. The carbon particles move through the bed in either co-current or counter-current direction in relation to the CO gas and such bed may be retained in an enclosure which is rotatable about a vertical axis to a body of molten alumina, which lies beneath it. Solid alumina may also be introduced into the carbon particle bed.  This is conveniently done by introducing the alumina particles into the top end of the bed with a downwardly flowing CO gas stream.

Abstract: ABSTRACT          A slack rope detecting apparatus for use in mine winding operations provides a trip signal via contacts 34 if the load in the rope falls below a predetermined value.   The apparatus senses the load at each side of a sheave wheel using transducers 6 and 8 and uses a mean value of their outputs as an input to a summation amplifier 12.   The weight of the rope between the sheave wheel is compensated for by monitoring rotation of the winding engine drum 42 and providing corresponding input signals for the amplifier 12.   When the effective load in the rope falls below a predetermined value, set by input 28, a trip signal is produced.   The trip signal output is preferably visually displayed and recorded.

Abstract: ABSTRACT OF THE DISCLOSURE A living, attenuated, oral vaccine system is described for the immunization against enteric disease.  This oral vaccine is a genetic hybrid derivative of an attenuated galactose epimeraseless strain of S. typhi which carries at least one protective antigen other than normal somatic S. typhi antigens.          The oral vaccine can provide protection against both typhoid fever and at least one other enteric disease.  A bivalent oral vaccine is described wherein the non-typhoid protective antigen is the plasmid-encoded form I antigen of Shigella sonnei.  A protective antigen from Shigella sonnei was transferred to a streptomycin resistant mutant of S. typhi strain Ty21a.  The transconjugant S. typhi strain expressed both S. typhi and S. sonnei antigens and protected experimental animals against lethal infections with either S. typhi or S. sonnei.  This strain is considered to be useful as a vaccine against typhoid fever and bacillary dysentery caused by S. sonnei.

Abstract: SYSTEM FOR MEASURING TORQUE AND/OR SPEED OF ROTATING SHAFT     Abstract:      A magnetic transducer (10) fits over a rotatable shaft (11)  and has a multi-pole magnetic core (30), one primary winding (46) being wound on half of the poles while a second primary winding (47) is wound on the other half.  Direct current pulses are alternately supplied to the two primary windings to provide a-c excitation for producing an alternating magnetic flux or field, adjacent to and within the shaft, which changes as the shaft is torsionally stressed when torque is applied thereto.   This stressing causes compression and tension in the shaft which alter the shaft permeability and thus vary the magnetic flux pattern in the shaft.  The resulting magnetic field is also a function of the shaft speed due to the shaft's armature reaction,  eddy currents being generated in the shaft which develop a counter magnetic field that opposes and distorts the field produced by the two primary windings.  A secondary circuit (51,52) in the transducer  (10),  comprising  a pair of  secondary windings  (38,42)  each wound on a  separate magnetic core (31,32), responds to the resulting magnetic field and provides information signals relative to the torque and speed characteristics of the rotating shaft.

Abstract: ABSTRACT OF THE DISCLOSURE    An aqueous emulsion of minute particles of calcium hydroxide formed by bringing porous and minute particles of practically pure calcium oxide into reaction with an excess amount of water is brought into reaction with an aqueous solution of phosphoric acid in an inert atmosphere, a milky reaction mixture containing the reaction product, hydroxyapatite is obtained.  After filtering, the separated cake is washed with water and dried to be an aggre-gate of hydroxyapatite having the following properties:         Analytical value of an atomic ratio of Ca/P: 1.67 to 1.69, Mean size of dimention of hydroxyapatite of length:  150 to 1200 .ANG. width:  50 to 400 .ANG., and ratio of length/width:  3 to 10.  Void: 0.2 to 0.8 cm3/g Mean pore-radius: 50 to 150 .ANG..  By firing the filtered cake, a ceramic material of hydroxyapatite having the following physical properties is obtained:       Analytical value of Ca/P  : 1.67 to 1.69, Mean crystal size         : 4 to 20 microns, and Density                   : 3.14 to 3.16 g/cm3.          The mean crystal size of the thus obtained material is larger than that of conventional synthetic ceramic material of hydroxyapatite.          The ceramic material of the present invention is prepared from the purer raw materials than those used for preparing the con-ventional materials.  In addition, even after firing of  the aggregate of hydroxyapatite at a temperature of 1350°C for one hour, no formation of whitlockite occurs, and no structural defects or decomposition occurs and the aggregate is excellent in thermal stability.  This invention relates to hydroxyapatite, ceramic material, implant material and a process for preparing thereof.  The ceramic material is hydroxyapatite ceramic having an excellent thermal stability.
