Abstract: A fiber optic video viewfinder for a motion picture camera.  The conventional ground glass focusing screen of the camera is replaced by a fiber optic element that comprises a fused coherent bundle of optical filaments.  A front face of the fiber optic element is located at the focal plane of the camera.  A video imaging device such as a photodetector array is secured to the opposite face of the fiber optic element. An image presented at the front face of the fiber optic element is transmitted through the element to the video imaging device whose electrical outputs are converted into a video image.   The fiber optic element may be tapered to provide image magnification or demagnification.

Title: Five-way adjustable form block holder with float capabilities
Inventor: CROUCH ROBERT H
IPC: B24B21/08
Filed: 1990-08-22
Granted: 1994-02-08
Abstract: A form block holder is provided for an endless belt type working machine such as a sander. Positioning of the block relative to the belt is provided in five distinct directions, i.e., up/down, forwards/backwards, yaw, pitch and roll, by a series of adjustments of interconnected shafts and sleeves. A float mode is also provided which yields to forces that tend to rotate the form block about an axis parallel to the belt travel and parallel with a support table, i.e., the pitch axis. A first end float shaft is surrounded by a support sleeve at one portion and is threadingly received in a handle. The remainder of the float shaft is surrounded by a cam sleeve comprising a first cam sleeve section ultimately connected to the form block holder and a second cam sleeve section. A spring biased washer is provided within the support sleeve about the float shaft and abuts the second cam sleeve section. To establish the float mode, a gap is provided between the support sleeve and the second cam sleeve section. Thus, pitch inducing forces cause the first cam sleeve section and form block holder to rotate about the float shaft, which in turn cause the second cam sleeve section to compress the spring biased washer. Once these forces terminate, the spring biased washer urges the second cam sleeve section back to its original position, whereby the first cam sleeve section and the form block holder are rotated back to their original positions.

Granted: 1995-05-09
Abstract: A programmable integrated circuit of the present invention can change the input system of serial/parallel input-parallel output device for inputting or outputting program data from serial to parallel or vice versa in response to a control signal from a control signal input device.    Therefore,  a  program  can  be  written  at  a relatively low speed through the parallel output of serial input, and a program can be written at a relatively high speed by inputting data in parallel and outputting the input data in parallel.   Moreover, the bit width of the aforementioned serial/parallel input-parallel output device can be changed in response to a control signal from control signal input device, whereby bit width for data input, shift and the like can be optimized according to the quantity of programs to be written with the result of improved freedom of users and the reduced time required for writing a large quantity of programs.

Patent CA-2061601-C (CA)
Inventor: ALLEN ROBERT CHARLES
IPC: A01N63/50
Filed: 1992-02-20
Granted: 2003-04-08
Abstract: Haloperoxidases are used to selectively bind to and, in the presence of peroxide and halide, inhibit the growth of target microbes without eliminating desirable microbes or significantly damaging other components, such as host cells, in the environment of the target microbe. When a target microbe, e.g., a pathogenic microbe, has a binding capacity for haloperoxidase greater than that of a desired microbe, e.g., members of the normal flora, the target microbe selectively binds the haloperoxidase with little or no binding of the haloperoxidase by the desired microbe. In the presence of peroxide and halide, the target bound haloperoxidase catalyzes halide oxidation and facilitates the disproportionation of peroxide to singlet molecular oxygen at the surface of the target microbe. The lifetime of singlet molecular oxygen restricts damage to the surface resulting in selective killing of the target microbe with a minimum of collateral damage to the desired microbe or physiological medium. The methods and compositions of the invention are highly useful in the therapeutic or prophylactic antiseptic treatment of human or animal subjects, since their use can be designed to be highly effective in combatting bacterial or fungal infections without significant damage to normal flora or host cells. Suitable haloperoxidases include myeloperoxidase (MPO), eosinophil peroxidase (EPO), laetoperoxidase (LPO), chloroperoxidase (CPO) and derivatives thereof capable of selective binding to target microbes.

Title: A convertible chair installation for or in vehicles
Inventor: CHRISTENSEN OLE VAGN
IPC: A47C17/16
Filed: 1992-05-29
Granted: 2002-08-20
Abstract: In so-called "ski-coaches", special chairs are used, the backrests of which can be swung up to form an upper row of bed elements, while the seat portions are completed with fill-in elements so as to form a lower row of bed elements.      Usually the backrests are of a design such that the chairs are unusable as normal coach chairs during the entire period outside the skiing season, and it is customary, therefore, to change out the entire seat installation before and after this season. According to the invention, the chairs are designed so that they will be universally usable, i.e. by way of a conventional front side profile and by an upper carrier element mounted inside the backrest, whereby the rear side of the backrest will not exhibit a visual sleeping fitting. The carrier element is located spaced underneath the top end of the backrest, whereby the sides of the uppermost portion of the backrest may be designed in an attractive, upwardly-converging manner.

Filed: 1993-01-08
Granted: 1997-07-08
Abstract: A single-phase half-pitch capacitor induction motor capable of being varied in rotational speed between a low rotational speed and high rotational speed.  The motor includes a main winding connected across a single-phase electrical power source and an auxiliary winding connected in parallel with the main winding.  A first phase shifting capacitor is connected in series with the auxiliary winding.  A second capacitor is connected in parallel with the first capacitor and a variable resistor is connected in series with the second capacitor. By increasing and decreasing the resistance, overall capacitance in series with the auxiliary winding is increased and decreased and the rotational speed is, thus, also varied.  A single pole, single throw switch or a thermistor can be used instead of a variable resistor for different applications.
