Title: Cuvette positioning device for optical analytical apparatus
Inventor: MACEMON JAMES H
IPC: G01N21/13

Granted: 1979-06-05
Abstract: CUVETTE POSITIONING DEVICE FOR OPTICAL ANALYTICAL APPARATUS            Abstract of the Disclosure Cuvette positioning apparatus for use in a spectro-photometer adapted for comparing first and second material samples includes a carrier in which cuvettes to be alternately analyzed are arranged end-to-end.  The      carrier is recipro-cated along a vertical axis to expose the cuvettes in alter-nation to the monochromatic beam of the apparatus.  The rate of reciprocation is selected to avoid cavitation of the samples, and a sinusoidal drive arrangement increases the exposure time of the samples to the light beam and minimizes transit time for optimum measurement efficiency.  Circuitry responsive to synchronizing signals derived from the drive arrangement is utilized to form an output signal indicative of the difference in measured characteristics between the samples.

Abstract: ABSTRACT           An electronic dryer for grain or other materials which includes a gas burner and one or more blowers for pro-viding heated air into a plenum chamber from which such heated air passes through the material to be dried between two spaced walls formed with openings such that the heated air can pass therethrough for drying the material. Temperature sensing means in the form of an elongated member such as a wire is mounted within the plenum chamber so as to detect the plenum chamber temperature and to control the duty cycle of the burner and second and third temperature sensing means are mounted between the spaced walls adjacent the inlet and outlet areas of the heated air so as to detect and determine the moisture content in the materials to be dried. These sensors are also elongated and detect the temperature at many portions of the dryer so as to more accurately determine the temperature.

Abstract: ABSTRACT OF THE DISCLOSURE         This is a method and apparatus for controlling a downhole, hydraulically actuated pump.  Two fluid flow monitoring means generate signals which are a function of the power fluid flow rate to the down-hole pump and the return fluid flow rate from the well.  An automatic controller causes the power fluid flow rate to be maintained essentially directly proportional to the return flow.  Thus, the power fluid flow is not varied in the opposite direction of any change in return flow to maintain the return fluid flow constant, but conversely, is changed in a manner which will tend to accentuate any changes in the return fluid flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A bore hole probe instrument having a point source of light, passing through a flexible tubular portion.  The point of light, which originates at one end of the flexible tubular portion, is established for example by means of fibre optics, a laser or the like.

Abstract: ABSTRACT OF THE DISCLOSURE          A method of separating individual assembly parts from a coherent mass of said parts resting on a support is disclosed.  The method  includes randomly sub-dividing the mass of assembly parts into clusters of said parts by continuously and successively lifting randomly selected ones of the clusters off the support and dropping the lifted clusters thereon until the mass is resolved into the clusters and the clusters are further resolved, the continuous and successive lifting and dropping of the clusters causing continuously changing portions of the mass and clusters to rest on the support and the support being continuously and successively relieved of the weight of the randomly selected lifted clusters of assembly parts.  The method also includes singling the resolved clusters into individual assembly parts and removing the individual assembly parts from the support.

Abstract: A B S T R A C T - CANADA      A terminal for two conductors has two slotted plates joined together in adjacent parallel planes with the slot mouths at least partly in registration.  The slots are formed with two wire-receiving sections.  In the first section, the slot walls of the first plate are offset in a first lateral direction from the slot walls of the second plate and in the second section the lateral offset is in the opposite lateral direction so that a conductor is gripped in the first section between a first slot wall of the first plate and a second slot wall of the second plate and in the second section between a second slot wall of the first plate and a first slot wall of the second plate.  The presence of the second conductor in the slots enchances the gripping force on the first conductor and vice versa.

Abstract: APPARATUS FOR RECORDING AND/OR    REPRODUCING VIDEO SIGNALS                     ABSTRACT OF THE DISCLOSURE in a VTR for recording and/or reproducing video signals in parallel tracks extending obliquely on a magnetic tape which is wrapped helically on a guide drum, rotary magnetic heads are associated with the guide drum to move in respective circular paths which coincide with the guide drum surface and which are axially spaced apart on the latter so that the heads obliquely traverse respective longitudinal zones substantially equally dividing the width of the magnetic tape.  The angluar spacing between the heads and the angular extent of the guide drum surface about which the tape is wrapped are selected so that, when the heads are rotated for obliquely traversing the respective tape zones in a repeating cyclic order, the latter has at least one overlapping interval in which two of the heads simultaneously scan oblique tracks in the respective zones.  In the reproducing mode of the VTR, signals reproduced by the heads from tracks in the respective zones and being scanned in the repeating cyclic order are sequentially combined and, during each overlapping interval, a comparator senses phase differences between signals reproduced by the two heads which are then simultaneously traversing the respective zones and provides a corresponding compared output.  A head shift signal is generated in response to such compared output and is employed, for example, by application to a bimorph leaf mounting at least one of the heads, for displacing such head in the direction along the respective tracks scanned thereby so as to eliminate the phase differences.

Abstract: 39,142 TIN-FREE CURRENT LIMITING FUSE   ABSTRACT OF THE DISCLOSURE   A current limiting fuse having a number of par-allel current conducting tin-free fuse links.  One of the fuse links is disposed in the centralmost part of the fuse along the longitudinal axis thereof.  The other parallel fuse links are radially or circumferentially disposed around the centrally located fuse link.  Ideally, all fuse links carry equal currents; however, the centralmost fuse link operates at a relatively higher temperature than those which surround it.  Consequently, the central fuse link will melt first during an overload condition, transferring the over-load current to the other surrounding fuse links which quickly blow because of the incremental change in current therethrough.

Abstract: MANUAL FLUID PRESSURE CONTROLLER    Abstract of the Disclosure A manual fluid pressure controller has a handle with integral cam which mates with a non-rotating cam follower.  Rotation of the handle causes displacement of the cam follower which transmits a force through a metering spring to a metering piston.  The metering piston actuates a combined inlet-exhaust valve to admit or exhaust fluid pressure to its one face until the spring force on its other side is balanced.  The fluid pressure at the face of the metering piston is connected to the load whose pressure it is desired to control. A cam stop, integral with the cam follower cooperates with a matching stop on the handle to limit handle travel.
