Abstract: 14.          ABSTRACT      A  foot-controlled  water  faucet  for  regulating   the outflow of water from a water faucet   by means of air pressure comprises  a  compressing  bladder 1 connected  with  an air bladder  81  in the water faucet by a passageway 3,  a  valve block  86, a ring body 67 and a knob 52 associated in  proper order  to  form  the  water  faucet.  When  stepping  on  the compressing  bladder 1 by foot the air inside is  compressed and  is squeezed  to the air bladder 81 in the  water  faucet via  the passageway 3. The air bladder 81 expands and  pushes the  platform 35 as well as the stem in the ring body 67  and the  valve block 86 respectively downward. The stem 18  moves away  from the opening of the valve block 86 and water  flows out. Water is stopped by releasing the  ompressing bladder  1 which sucks back the air from the air bladder 81 that is then contracts and allows the stem 18 to move back to the original position.  It can also be controlled by hand as  an  ordinary water faucet. (FIG 5)

Title: Secure image production
Inventor: RADCLYFFE EDWARD STANLEY
IPC: G03B7/00
Filed: 1990-04-27
Abstract: Abstract A laminate containing an image is produced by printing the image on a layer of a high temperature glue which has been applied to a layer of a transparent medium.  The image is printed on the glue layer using carbon or a carbon-containing compound that does not flow when applied to the glue surface.  The combination of transparent medium high temperature glue and image is then bonded to a substrate using a thermal bonding process to produce a laminate of the transparent medium and the substrate.  The image is not distorted by the thermal bonding process,  but remains clearly visible through the transparent medium.  Typically the transparent medium will be a polyester film or a sheet of glass beads dispersed in glue.  One or more additional layers may be bonded to the substrate to increase the stiffness of the product laminate.

Abstract: Construction block with guiding system for walls ABSTRACT     The present invention relates to a block for the construction of a wall which is made of a plurality of similar blocks disposed one upon the other in horizontal courses in end to end relation and to overlap the adjacent ends of the blocks forming the next below course of blocks. The block comprises a top, a bottom, a front, a rear and side faces. The bottom face of a block further includes guiding means extending from same. The bottom face of a block of a subsequent course of blocks also has a complementary shape with respect to the top face of a block from the next below course of blocks so that a relative movement, such as a rotation, is possible with respect to an axis generally perpendicular to the top and bottom faces. Upon the erection of the wall, the guiding means of a specified block of the subsequent course of blocks rests on the rear face of adjacent blocks of the next below course of blocks and the guiding means are used to guide such relative movement of each block of the subsequent course of blocks with respect to the next below course of blocks in order to create a wall which, when viewed from above, can be flat, rounded or a combination of both and this, without the necessity of providing different types of blocks for different types of applications. In addition, the erection of the wall does not necessitate any special tooling. Dueto the guiding means, each overlying horizontal course is automatically set back from the next below horizontal course.

IPC: A61D19/00
Filed: 1993-03-23
Abstract: SYNCHRONIZED DONOR CELLS FOR BOVINE NUCLEAR TRANSFER            Abstract A method of multiplying bovine embryos by nuclear transfer includes the steps of synchronizing donor embryonic cells at a cell cycle phase using a cell cycle inhibitor, releasing the cells from inhibition, and allowing the cells to progress into the S-phase of the cell cycle before fusion to recipient oocytes.  In a preferred process, the recipient oocyte is activated before fusion such that both donor and recipient are in S-phase when fusion occurs.  More preferably, the cell cycles of both donor and recipient are coordinated before fusion such that both donor and recipient would re-enter M-phase at about the same time.  The method is intended to increase the percentage of viable bovine nuclear transfer embryos to a percentage higher than can be obtained without synchronization of donor nuclei.
