Title: Tunnelling shields
IPC: E21D9/087
Filed: 1978-07-19
Abstract: A tunnelling digger shield is disclosed which, is constructed in two main parts which are detachably connected to each other, the parts being a cylindrical cutting head driving unit (1) carrying a motor (12) for driving a cutting head (34) which, in use, is fitted to the unit, and a cylindrical thrust unit (15) carrying hydraulic shove rams (20) for advancing the shield. When a different diameter tunnel is to be driven, the shield is easily modified to change its effective diameter as necessary, either by fitting cylindrical shells to the cutting head driving unit (1) and the thrust unit (15), or by replacing the whole thrust unit (15) by one of a different size. The same cutting head driving unit (1) is used for each different diameter shield, although the actual cutting head (34) will be changed. <IMAGE>

Title: A Process for the Production of a Membrane Separator
IPC: H01M50/494
Filed: 1978-07-20
Abstract: A process for the production of a membrane separator for use in an alkali accumulator battery comprises activating a film of a polyolefin such as polyethylene by irradiation with ultra violet light, covering both sides of the film with at least one layer of an absorbent cellulose material, such as cotton gauze, impregnated with a vinyl monomer, and covering the sides of the cellulose material remote from the film with a sheet of an inert plastics material to form a five layer sandwich. The sandwich is then passed over a heating element under a load of from 10 to 30 gm/cm<2> for a period of from 10 to 45 minutes to effect grafting of the vinyl monomer onto the polyolefin thereby to form a said membrane separator. For economic reasons, it is desirable for the sandwich to have a continuous length: in this way a continuous production line may be established.

Title: Electrostatic recording medium
IPC: G03G5/02
Filed: 1979-04-05
Abstract: Copolymer comprising a major amount of hydrophobic monomer such as acrylic ester, methacrylic acid ester, aromatic vinyl and vinyl cyanide, and a minor amount of hydrophilic monomer such as acrylic acid and methacrylic acid is stably dispersed in water without the aid of emulsifier. An electrostatically-recording medium is produced by the application of the aqueous dispersion of said copolymer on a supporting member having a low-resistance back surface to form an image-holding layer. This electrostatically-recording medium has advantages in which, upon its production, there is no need of using inflammable solvent and emulsifier and also, upon high-speed imaging process, high-quality images are provided even under high-humidity condition. Polyethyleneimine and polyepoxy compounds may be added to the aqueous dispersion to crosslink the copolymer, thus resulting in the improvement of recording characteristics. To be further effective in writing quality, polyacrylamide may be added.
