Abstract: 632,767. Moulding reinforced asbestos cement sheets by rolling. TURNERS ASBESTOS CEMENT CO., Ltd., and NASH, F. L. Oct. 20, 1947, No. 28042. [Class 87 (ii)] A method of and apparatus for making reinforced sheets of asbestos cement or like material comprises building up a coating of the moist material on a rotating cylinder and introducing sets of reinforcements of predetermined lengths into the coating as it is being built up, so that the reinforcement is wrapped around the cylinder and leaves at least two short circumferential lengths of the built-up coating un-reinforced. The sheet so formed may be itself cut into shorter lengths by cutting or parting across one of the un-reinforced short lengths. Specification 593,624 describes and claims a similar form of apparatus for feeding reinforcing wires lengthwise to the rotating cylinder of a like machine In the machine shown in Fig. 2, an endless felt band 1 carries asbestos cement slurry into contact with the rotating cylinder 3 so that successive laminations are built up on its surface. The predetermined lengths of reinforcement are fed to the cylinder through tubes 11 and 12. Cams 43, 44 carried by a lever arm 41 on an extension 45 of the cylinder shaft actuates switches 39, 40 controlling the feed of the wires to the cylinder in correct time sequence by means of solenoids 31, 32, operating spring-controlled plates 16, 17, Fig. 1 (not shown), covering ports in the guide plates 18, 19. In operation the coatings are built up to approximately half the desired thickness and the lever 41 is then moved so that the cams operate the switches and feed the reinforcement to the cylinder. A further coating is then applied to finishing thickness and the layer parted to form a sheet which may itself be cut into shorter sheets. A modification has the switches 39 and 40 fixed in contact with the cams.

Title: Conforming bandages
Inventor: SULLIVAN DENNIS BENEDICT
IPC: A61L15/46
Filed: 1953-10-12
Abstract: A conforming bandage is made from a fabric composed of kinked threads and a selvedge is formed by merely turning in the edges, the threads then interlocking to maintain them in position.  The bandage is preferably made of cotton fabric, of which the yarns are twisted and shrunk, the shrinking being done after the folding over of the edges and, if desired, after the bandage has been rolled, so that pressure may be applied to its edges to assist shrinkage.  Wetting and bactericidal agents are preferably incorporated in the shrinking bath.  The inturned edges may be only marginal to form a single thickness bandage, edge to edge for double thickness or completely overlapped for treble thickness.

Abstract: 1377128 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 28757/74 Divided out of 1377121 Heading H1K In a charge coupled circuit utilizing overlapping electrodes spaced from the substrate by insulation, the separation between the overlapping parts of the electrodes is equal to or less than the thickness of the underlying insulation, the effective thickness of which is not more than half of the depth of the depletion regions created in the substrate by the phase voltages which are selected in accordance with various parameters of the device so that the voltage difference between adjacent electrodes produces a fringing field in the substrate effective to enhance the speed of charge propagation. An equation is quoted giving the tranfer time due to the fringing field in terms of the voltage difference between the electrodes, the electrode lengths, the spacing of the electrodes from the substrate, and the charge carrier mobility. By appropriate design of the circuit to ensure that charge transfer is to a large extent effected by the fringing field the whole of the charge can be transferred in a time of the order of nanoseconds, whereas reliance on the drift field results in much longer transfer times and incomplete charge transfer. The fringing field may be increased by increasing the substrate bias utilized.
