Abstract: ABSTRACT OF THE DISCLOSURE         An interlocking molecular model system includes a component that represents an atom and has an elongated shank extending outwardly.  The outermost part of the shank has a larger diameter than the portion of the shank immediately adja-cent it on the side toward the location representing the center of the atom, and the differences in diameter form a shoulder to be grasped by a hollow tubular fastener component slotted at one end so that it can slip over the enlarged outermost part of the shank and fit behind the shoulder.  The combined length of the shank and the fastener component represents the covalent radius of that atom, and the shank has an abutment that limits the extent to which the fastener component can be pushed toward the part of the atom representing the nucleus, thereby maintain-ing the proper representation of molecular distances in the model The fastener component can have a flange to be joined to a generally similar fastener component to engage another shank on another component representative of an atom.  Another component has a hollow tubular portion to fit over the shank of the first component and has a generally spherical end facing away from its hollow tubular portion so as to give an appearance somewhat similar to a space-filling model.  The fastener components and shanks can be keyed to set angular relationships in a complex model built of the components.

Abstract: ABSTRACT OF THE DISCLOSURE An eave trough protector adapted to be secured to a surface of a building, preferably a vertical surface of the building adjacent the edge of the roof, to support a. ladder against lateral slippage and to protect the eave trough from damage when persons climb the ladder to gain access to the roof of the building.  The protector includes a pair of supports each having upper and lower arms which rest against the vertical surface of the building.  The protector further includes a spacer bar and the supports are secured to opposite ends of the spacer bar.  The spacer bar is bolted to the eave trough and the distance between the supports corresponds to the width, of a ladder so that when a ladder rests on the spacer bar, the ladder is prevented from sideways or lateral movement by the supports.  The protector prevents the ladder from damaging either the roof or the eave trough and operates on a self-energizing principle in that as a person ascends an inclined ladder, the increased weight on the ladder and more specifically the horizontal component of the weight causes the protector to be urged more tightly against the vertical surface to reduce any possibility of slippage of the protector.

Abstract: AUTOMOTIVE BATTERY TEST APPARATUS     ABSTRACT OF THE DISCLOSURE           The condition of a storage battery of an internal combustion engine powered vehicle is tested automatically, and an indication of battery condition is provided to the service technician.  The battery testing apparatus is connected to the positive (+) and negative (-) terminals of the battery to measure battery voltage under several different conditions. In particular, the battery testing apparatus measures battery voltage under open circuit conditions, while subjecting the battery to a predetermined AC load, and while subjecting the battery to a predetermined DC load.  The battery testing apparatus also includes a temperature probe which measures the temperature of the battery.  A digital computer control utilizes the measured open circuit voltage, the measured voltage under a predetermined DC load, and the measured voltage under an AC load (which represents dynamic internal resistance of the battery) and the temperature measurement to provide an indication of battery condition based upon these measured parameters and stored data for normal characteristics of the battery under test.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for minimizing backlash and improving  the efficiency of  speed reduction mechanisms in which a series of  rollers are equally  spaced  in a circle on a disk to perform operationally somewhat like an internal ring gear. Mounted for eccentric movement and simultaneously engaging each of the rollers is an orbital rotor having a perimeter defined by an epitrichoid curve with a number of lobes equal to one less than the number of rollers. The rotor is mounted for free rotation on an eccentric keyed to a drive shaft. Rotation of the drive shaft causes the rotor to move orbitally and to rotate with a speed reduction equal to the reciprocal of the number of  lobes on the rotor. A similar structure may serve as a second stage with a second orbital rotor dri-ven by the first rotor and moved orbitally by the same eccentric. In carrying out the method of this invention, each of the rollers is individually adjusted to bring it into engagement with the rotor under controlled pressure and compliance.  Each  roller  is mounted  for  controlled omnidirectional  compliance  and preloaded  to provide  a controlled pressure between each roller and the adjacent surface of the rotor. The outer surface of each roller is crowned to increase the efficiency and prevent binding that might be caused by angular deflection of the roller.     Each roller  is mounted on a shaft  that  is press-fitted into an eccentric bore in a mounting sleeve that is enlarged  near the  roller  to provide  for  controlled deflection of the shaft as the sleeve is rotated in its mounting. Each roller is individually adjusted to produce a controlled preload pressure between the roller and the rotor.

Abstract: Abstract of the disclosure:     A hybrid plasmid with the replicon inherent to the methylotrophic bacterium is obtained from a plasmid from obligate methylotrophic bacteria, for example Me-thylomonas, on the one hand and a plasmid with selec-tion markers on the other hand.  This hybrid plasmid is introduced by transformation into a host organism such as E. coli, if appropriate after previous introduction of further genetic information.  After amplification and appropriate selection, the clones are treated with a suitable conjugative plasmid, and the mobilizability de-fect is abolished by introduction of a further suitable plasmid.  The clones thus obtained are conjugated with, preferably plasmid-free, obligate methylotrophic bacte-ria as recipient, clones being obtained, after selec-tion, which express proteins corresponding to the gene-tic information introduced.  It is also possible to pre-pare spheroplasts from the bacterium serving as the re-cipient and to insert the hybrid plasmids into the for-mer by transformation.
