Abstract: ABSTRACT OF THE DISCLOSURE            A  block  for  use in construction,  particularly though not exclusively paving,  has top and bottom surfaces one of which is a rectangle and the other of which is a square or a rectangle.          In the case where the other surface is a rectangle the block has the major axes of the rectangles mutually perpendicular and has a  shape at mid-height in horizontal cross-section which is sub-stantially a  square and  the  length of  the  side of said square is within the range 66% to 300% of the height of the block.  In the case where the other surface is a square, the major axis of the  rectangle is  greater in length than the side of the square and  the  said  square  has a  side of length within the range 66% to 300% of the height of the block.

Abstract: ABSTRACT           A novel apparatus and method for improving the stability of an electrical circuit such as an oscillator and/or a radio frequency transmitter which is coupled to a radiating element wherein the radiating element such as a loop is coupled to the inductor or capacitor of the frequency determing circuit of the oscillator so that frequency shifts will not occur due to inductive or capacitive effects.  The oscillator circuit is mounted on an insulating sheet which has a ground plane on the opposite side thereof so as to provide effective shielding and the radiating element is mounted on a portion of the insulating sheet where the grounding plane does not extend.  The radiating element is also coupled symmetrically to the inductor or capacitors of the frequency determining circuit and is connected at tap points which do not have the entire inductance between them.

Abstract: A METHOD FOR DETECTING AN ERROR     BIT IN A MULTI-BIT WORD           Abstract of the Disclosure A method and apparatus for storing data in which the data is checked for an error without requiring the data to include an error correction code.  Included in the system is a logic circuit for dividing a data word by a polynomial during the time the data word is being written into the primary memory unit resulting in the generation of a remainder which is stored in an auxiliary memory unit.  When reading the data word from the primary memory unit, the data word is again divided by the same polynomial and the remainder compared with the remainder stored in the auxiliary memory unit.  If the remainders match, no error as introduced during the storing of the data in the main memory unit.  If the remainders do not match, an error is indicated.  This system allows a data word to be stored in a main or primary memory unit without requiring the word to in-clude error correction bytes.

Abstract: ABSTRACT OF THE DISCLOSURE         Single-pole switches are customary in middle voltage networks in the U.S.A. and in other countries with similar distribution systems.  A switch safety device acts as a? single-pole switch element, such a switch device is usually combined with an extinguishing device for normal load currents.  In order to improve safety, a plurality of conventional load-disconnec-ting switches are arranged in a common frame, and each load-dis-connecting switch permits individual switching.  This is made possible by hubs arranged on a common shaft within the common frame. In each instance, these hubs constitute the connection to a load-disconnecting switch and an associated drive.  In addi-tion, each load-disconnecting switch may be provided with a holder, into which an HH-type fuse can be inserted.

Abstract: EXPANDED METAL SADDLE TOWER PACKING                 ABSTRACT OF THE DISCLOSURE      Tower packing elements adapted for dumped packing and employed to effect vapor-liquid contact in vapor-liquid con-tact columns for the purposes of bringing about mass and heat transfer between the liquid and vapor phases.  Each packing element is of the saddle variety and is arcuately formed about orthogonal notional axes.  The body of the saddle comprises expanded metal; that is, metal that has been perforated, lanced, and/or expanded by stretching along oppositely oriented axes.  Also disclosed are methods of forming a segmented, semi-toroidal tower packing element from metal which has been expanded, as well as from metal which has been slitted, and which is expanded at the same time as it is formed into a saddle shape.  In this manner, the advantages of metal in tower dump packing can be uti-lized in a saddle configuration maximizing vapor-liquid con-tact and efficiency of the mass and heat transfer.

Abstract: Abstract An  apparatus  (20)  for  incubating  fish  eggs  is disclosed.   The incubating apparatus (20)  includes an insu-lated container  (22)  for holding a plurality of preferably square tubes  (24).   Apparatus  (20)  is portable and may be operated in a recirculation mode or by running external water through  it  continually.   In  the  recirculation mode,  water flows about a fluid circuit.  An air pump (90) provides air to an air diffuser (104).   The bubbles from diffuser (104) lift water in air lift tube (86) to tank (88).  The water in tank  (88)  provides  a pressure  head  to  force  the  water throughout the rest of the circuit.  Water from tank (88) is communicated  through a  filter  (122)  to a manifold chamber (34).  The water is distributed from manifold chamber (34) to the  plurality  of  tubes  (24).   As  the water  rises  upward through tubes  (24),  it aerates and cleanses the incubating fish eggs.    Since the upper portion (54) of tubes (24) is screened, the water has a common level throughout container (22).   The water flows between tubes (24) out an exit pipe (50) and back to air lift tube (86).  The present apparatus (20) provides a portable incubating device as a replacement for stationary fish hatcheries.

Abstract: A B S T R A C T     A method for in vitro evaluation of focal length changes in a lens is disclosed, involving the steps of projeoting parallel laser beams through the lens at at least two points, examining the convergence of the beams after exiting the lens to determine the focal length of the lens, and after a period of time, repeating these steps and comparing the focal length. Preferably, a scanning laser is used so that a number of beams pass through different spots on the lens, so that the spherical aberration of the lens may also be determined and compared over time. Apparatus is disclosed for carrying out the method, comprising a carousel plate having a number of spaced holes for receiving lens containers. A carousel drive servo motor rotates the carousel from lens container position to lens container position. A helium-neon laser is mounted horizontally on an X-Y table, and the laser beam is deflected upwardly through a lens held in a lens container. Mirrors provide a video camera with two views of the lens focal point area, the viewpoints being offset from each other by 90 degrees. The video camera signal is fed to a personal computer for analysis. A display monitor and printer are connected to the computer. The software may be directed to display and print the actual video camera image, or to digitize the information and produce a display or printout illustrating the spherical aberration of the lens.

Abstract: ABSTRACT OF THE DISCLOSURE:           Concentrated, stable water-in-oil emulsions of water-soluble or water-swellable polymers are prepared by polymerization of one or more water-soluble ethylenically unsaturated monomers in a water-in-oil emulsion and removal of water from the water-in-oil polymer emulsion by azeotropic distillation,  by a method in which superheated vapor of an inert organic solvent which is immiscible with water is passed into the water-in-oil polymer emulsion.          Using the process,  it is also possible to concentrate emulsions which tend to coagulate or water-in-oil emulsions which are sensitive to shearing, without the polymers losing their effectiveness.
