Abstract: A design is for a Congreve-style clock that keeps time more accurately, i.e. that is insensitive to minor variations in friction on the ball, in which the depth of each groove in the inclined plane varies along its length so that the path of the ball approximates a cycloid on each traversal. The grooves provide alternating paths that overlap such that the distance that the ball travels varies with the speed of the ball. In such system, increased friction causes the ball to move more slowly, but because the slower ball also follows a shorter path, the time required to reach the bottom of the inclined plane remains the same. Similarly, decreased friction causes the ball to travel more quickly, but a faster moving balls takes a longer path.

Abstract: Shaped concrete blocks are provided each having generally parallel top and bottom surfaces, a shaped front face (adapted to be exposed as the wall element), side walls and a rear wall. The one surface of each block is provided with transverse shallow groove, while the other surface of each block is provided with a conforming rib positioned correspondingly with the grooves. In this manner, successive blocks may be stacked on top of one another with the ribs engaging in the grooves.

Abstract: A method for enhancing and/or increasing the efficiency of repair of tissues, primarily bone or cartilage, using genetically engineered cells has been developed. In the preferred embodiment, mesenchymal stem cells are isolated from periosteum tissue, and transfected with the gene encoding a growth factor for the particular cell type to be repaired. For example, for repair of bone, a gene (or genes) encoding bone morphogenic protein is transfected into periosteal cells. The transfected periosteal cells then express the bone morphogenic protein in culture to promote bone repair as a function of the expressed bone morphogenic protein. Cells can be transfected using any appropriate means, including viral vectors, as shown by the example, chemical transfectants, or physico-mechanical methods such as electroporation and direct diffusion of DNA.

One end of the transformer is connected to a metal AC line input prong, and another end is connected to supply power to a signal amplifying circuit. The signal amplifying circuit and transformer are fixed to the plastic material shell so that the metal prong projects to the outside of the shell. The shell further includes input and output terminals and selective switches, including a gain select switch and an input select switch.

Abstract: A car-used spare power system quick charging device including a switch, a boosting circuit, a detecting circuit, an indicating circuit, an unstable circuit, a pulse cutting circuit and multiple charging batteries. The detecting circuit serves to detect the voltage state of the charging battery. The indicating circuit serves to indicate the voltage state of the charging battery detected by the detecting circuit. The switch is used to switch the charging/discharging modes. When the charging battery is detected to be in middle or low voltage state, the boosting circuit serves to boost the charging battery into high voltage. The charging battery charges/discharges the car battery by way of pulse so as to protect the charging battery from damage due to over-heating and make the charging battery 100% release voltage.

Abstract: A heat-radiating structure of power adapter, including an outer housing, a front sealing board, a rear sealing board, a circuit board, a heat-conducting member and a bottom board. At least one side of the circuit board is connected with a heat-conducting member. The heat-conducting member is disposed between multiple heat-conducting rubbers and the outer housing and padded by an insulative heat-conducting sheet. A metal plate formed with thread hole is together with the heat-conducting member screwed in the outer housing. The heat-conducting rubber and insulative heat-conducting sheet serve to evenly conduct the heat to the outer housing. The exhaustion fan serves to suck in air to cool the metal plate in the outer housing so as to greatly increase the heat-radiating area and achieve a better heat-radiating effect.

Abstract: An inflatable sports ball has a body with a multiplicity of discrete panels joined together at seams along respective adjacent edges by stitching, preferably machine stitching, to define a volume, and an inflatable bladder disposed within the volume, with a valve extending through an aperture defined in the body outer surface. Each ball panel is formed of a multi-layer laminate consisting of an outer layer of synthetic polymeric material, an intermediate layer of expanded synthetic polymeric material and a woven fabric, and an inner layer of woven fabric. A method for manufacturing an inflatable sports ball using a stitching machine to join pairs of panels at a seam along respective adjacent edges is also described.
