Abstract: An improved method and apparatus for generating video images of the internal structure of a body is disclosed. A contrast medium is injected into the vessel to be imaged. Radiation is directed at the body, and radiation which passes through the body is detected and converted into a series of frames of electronic video signals, preferably in digital form. The frames represent images of the radiation transmission characteristics of the body at a series of successive times. Each frame includes an array of pixels, the video level at each pixel of a frame being determined by the radiation transmissivity of the body through an elemental region thereof. An initial video frame, i.e., the first video frame generated after the initiation of video processing, is stored in a digital video frame store. The video signal level at each pixel of the next frame is compared to the video signal level of the corresponding pixel of the stored frame. The lower of the two video signal levels being compared is selected and said selected video signal level is re-stored (in place of the previously stored value) at the particular pixel in the video frame store. This is done for each pixel of the frame. The process is then repeated for subsequent frames. In this manner, the stored video frame is dynamically processed to retain, at each pixel, a video signal level that represents the highest opacity to radiation during the video processing period through the elemental region of the body that corresponds geometrically to the particular pixel.

Abstract: ABSTRACT A loading dock shelter for use around a doorway on wall, includes a flexible head cover panel, having top, bottom and side edges. Two sleeves, each sleeve secured to opposite side edges of the head panel to an intermediate area between the top and bottom edges, slidably receive two flexible elastic straps respectively. One end of each strap extends upward toward the top edge of the head panel and one end of each strap extends in a taut draped manner from the sleeve. The ends of the strap are secured in a stationary manner to the side frame member. The flexible elastic straps restrain and cushion the head panel as the head panel is subjected to outside forces reducing strain and wear, yet allowing the head curtain to yield upon engagement with a truck.

Abstract: ABSTRACT OF THE DISCLOSURE A door assembly in a construction for preventing the transition of interference fields, in particular of high-frequency electromagnetic fields, into a space, wherein the contact zone between the door and a stationary structure is sealed by a labyrinth construction which attenuates the transition of interference fields.          In prior art constructions, the provision of such labyrinth con-structions increases the difficulty of door operation as a result of the high compression force which is required for closing the door as well as the tendency of the pivoting movement of the door to damage the labyrinth construction.  In order to overcome this problem, apparatus are provided such that the movement of the door comprises the usual pivoting movement thereof with respect to an axis and, additionally, a substantially linear controlled final path of movement during which a contact preventing the transition of interference fields is produced.

Abstract: LIFTING AND DEPOSITING DEVICE FOR PORTABLE CONTAINERS  COMPARTMENTS, CONTAINERS, SHELTERS OR THE LIKE                ABSTRACT OF THE DISCLOSURE For the handling of portable large containers, lifting and depositing devices are used, which have rack and pinion jacks to be attached to the corners of the containers by means of brackets.  These rack and pinion jacks have tubular winch shanks which are approximately the height of the containers, into which are guided tubular uprights with the racks.  Because of tolerance variations, the danger here arises of an impaired guidance of the uprights with the result of a poor operation of the gearing.  To avoid this difficulty, a guide tube is connected with the bottom end of each tubular winch shank. Guide surfaces in the guide tube can be produced with great precision and at low cost.  The housing of the winch gearing is configured integral with the guide tube.  Thus, a small amount of side play can be left between the upright and winch shank without adversely affecting the rack and pinion gearing operation.

Abstract: ABSTRACT     DRIVE LINE FOR A TANK           A  tank engine drive shaft (1) drives respective tank tack drive shafts (20, 30) by way of a continuously-variable      ratio     transmission variator (200), a transfer system (12, 13, 15) including coupling means (C1, C2, 16, 17), a cross shaft (18, 19) and respective summing epicyclic gears (7, 6).  Steering of the tank is achieved by a steer variator (100) also driven (2, 3) by the engine, which outputs differential rotations as further inputs (82, 55) to the summing epicyclic gears (7, 6).  The drive line operates in four distinct regimes: reverse, low I, low II and high, by means of an epicyclic gear brake (8), and clutches (H, C1 and C2). The two parts (16, 17) of the coupling means are made to rotate in opposite directions by the annulus (15) of the epicyclics.         As the tank accelerates from rest in low I regime, with brake B applied and clutch C1 applied but clutch H disengaged, the cross shaft (18,   19)   decelerates.    At   a   predetermined forward speed, the cross shaft is stationary and the change to low II is effected synchronously.          As the tank accelerates further forwards in low II regime, the cross shaft accelerates from rest in  the  opposite  direction,   with  clutch  C2 instead of clutch C1 engaged.     The  use of  the  same  transfer  system  for  both parts of  the low regime  enables  the  use of  a smaller   variator   (200)   for   an   equivalent performance.

Abstract: CLEANING AND DISINFECTING SYSTEMS             INCLUDING COLOR DISPLAY MEANS              Abstract Of The Disclosure A process for detecting the depletion of a clean-ing and disinfecting ingredient in a solution such as the water present in a toilet tank and bowl.  A solid composi-tion comprising a color indicator in a matrix is located in the solution along with the ingredient.  The porosity of the solid composition is maintained within limits to provide a means for controlling the rate of release of the color indicator into the solution.  The cleaning and dis-infecting ingredient has a bleaching tendency relative to the color indicator so that a display of color is minimal or non-existent for as long as significant amounts of the ingredient are present.  The color indicator is provided in sufficient amounts so that, when considering the controlled rate of release, there will be continued release of color indicator after depletion of the ingredient.  This will then provide a substantial display of color whereby deple-tion of the ingredient can be detected.
