Abstract: Abstract of the Disclosure An optical scanning system for a variable-magnification electrophotographic copier includes a first scanning carriage reciprocated along a path by endless bands attached to the carriage at transversely spaced locations and driven purely by friction.  Pulleys mounted on a second scanning carriage at transversely spaced locations roll between the drive bands and stationary guides to move the second carriage at half the speed of the first carriage.  The second carriage may be shifted relative to the first carriage by moving it to a location at which arms lift the pulleys from the guides.  A flywheel rotating at the desired scanning speed is coupled to the scanner drive train after the drive train has been smoothly accelerated to the desired scanning speed, and is uncoupled from the scanner drive train before the drive train is decelerated at the end of the scanning stroke.  Misalignments between the separately driven ends of the first carriage are corrected by intercepting the carriage ends to induce differential slippage in the portions of the drive train coupled to the respective carriage ends.  Similar misalignments between the separately driven ends of the second carriage are corrected by commonly rotating gears at the respective carriage ends that mesh with fixed teeth at one end of the scanning path.  Misalignments between the first and second carriages are corrected by a gear, carried by one of the pulleys of the second carriage, which meshes with a normally immobilized gear as the second carriage moves past the same location.

Abstract: Abstract Vehicle Protection System A automatic vehicle protection system, e.g. for a railway vehicle, in which continuous contact is maintained with a train via transmissions carried by the normal track circuit signals.  Information relayed to the train through these transmissions may concern speed limits, forward section occupancy and so on which can replace normal track side visual signalling systems as a means of controlling trains.  It is, therefore of utmost importance to ensure that a train receives the correct transmission, which it is intended to receive, and not those meant for other trains.  By arranging for track circuit signal frequencies in predetermined sequences and providing the train with means for determining whether or not the sequence of frequencies it encounters as it traverses a line the safety of the train, and the integrity of the system, may be continuously proved. In the event that the train encounters an invalid frequency sequence the emergency brakes may be brought into action, alternatively the train may be permitted to continue but at a reduced speed.

Abstract: Abstract of the Disclosure A quick-release mounting for a cutting wheel comprises a housing adjustably mounted in an arm, and a hollow shaft rotatably supported in the housing.  The shaft has an expandable collet hub on which a wheel can be received.  A mandrel extends within the shaft and has a tapered part to expand the collet hub; the mandrel is spring loaded toward expanding the hub, and a handle on the mandrel allows thrusting the mandrel in opposition to the spring load for release of a wheel.  Locking members guard against accidental release of a wheel from the shaft, and an adjustable stop prevents over-tightening the collet hub.  Adjustments of the mounting to mount or dismount a wheel and to change position thereof can all be accomplished without need for tools.

Abstract: FORMING CHAMFERED FLANGE AND SPLINES          IN THIN-WALL MEMBER                 ABSTRACT OF THE DISCLOSURE      A  power  transmission  member  (42),  as  well  as apparatus  (10,110,210) and method for forming the power transmission member (42)  from a thin-walled blank.   The apparatus (10,110,210) comprises a pair of opposed toothed dies (26,30;112,114;138,140).   A toothed mandrel  (40) is rotatably supported between the dies and received within the sleeve portion  (46), flatly engaging an annular end wall (44) of the member.  The dies (26,30;112,114;138,140) and  mandrel   (40)   have   chamfered  surfaces   (68,70), respectively, for forming a chamfered flange (66) on the power transmission member (42) as the toothed surfaces of the  dies  are  relatively  moved  during  the  splining operation.  A loading notch (122) is formed intermediately along  the  toothed  work  surface  of  each  die  member (112,114;138,140) for receiving a blank to be splined when the notches (122) are vertically aligned with one another in a neutral or loading position on opposite sides of the mandrel.    Groups  of  rough  (124,126,128)  and  finish (130,132) forming teeth are spaced along opposite sides of the notches  (122), and progressively increase in height from  group-to group  away  from  the  notches.    Initial opposed movement of the dies  (112,114;138,140) from the loading position simultaneously engages opposing pairs  of similar rough forming teeth (124,126,128) and the mandrel teeth  (48)  with  the  sleeve  portion  (46)  therebetween, rough forming splines therein.  The dies (112,114;138,140) are then moved in the reverse direction, simultaneously engaging  opposed  pairs  of   similar  finishing  teeth (130,132) and the mandrel teeth (48) with the sleeve (46) therebetween to finish forming the splines (64) therein.     Opposed   rows   of   raised   synchronizing   teeth   (142) respectively extend along the toothed work surfaces of the dies  and  mandrel  and  are  spaced  inwardly  therefrom, meshing together to rotate the mandrel and coordinate the relative  movement  of  the  dies  and  mandrel  during  a splining operation.

Abstract: Abstract There are described ruthenium complexes to which an immunologically active material can be or is coupled. The ruthenium complex has the general formula                   I   wherein L1, L2 and L3 are the same or different and each signify a bi- or polycyclic ligand with at least two nitrogen-containing heterocycles, whereby at least one of these ligands is substituted with at least one group conferring water-solubility, and whereby at least one of these ligands is substituted, optionally via a spacer group, with at least one reactive group, and whereby the ligands L1, L2 and L3 are attached to the ruthenium via nitrogen atoms.     The ligands L1, L2 and L3 contain e.g. a 2,2'-bipyridine, 1,10-phenanthroline, benzbathophenan-throline or bathophenanthroline group.     The spacer group is e.g. an alkylen group with a maximum of 8 C-atoms which is optionally substituted with -SO2-NH-, -S-, -O-, -COO- or -CO-NH-.     The active group, to which the immunologically active material is coupled is e.g. a -COOH, -I, -NH2, -NCS or -SO2Hal group.     As immunologically active material which can be coupled to the above mentioned ruthenium complexes come into consideration especially antigens, haptens or antibodies. e.g. antibodies to carcinoembryonic antigen.     The ruthenium complexes according to the present invention can be detected with great sensitivity by fluorescence spectroscopy.

Abstract: ABSTRACT        A process for preserving fresh fruit/vegetable products comprises the steps of; heating the fruit/vegetable product rapidly and uniformly to a temperature sufficient to destroy the natural enzymes which are present in the product without cooking the product, and immediately thereafter, cooling said product rapidly to a cold condition to remove the enzyme destroying heat before any significant cooking of the product can occur and to cool the product to a temperature which will inhibit deterioration of the freshness thereof.  Shortly thereafter, while the product remains in said cold condition, it is placed in a sealed gas-type package.  Shortly thereafter the packaged product is irradiated to an extent sufficient to sterilize the product and prevent the formation of degenerative gas in the product, without damaging the product to thereby provide an enzyme-free, sterile and hermatically packaged fruit/vegetable product which has its fresh flavour and texture characteristics substantially unaltered and which can be stored without deterioration of freshness, flavour or texture for a long time.
