Title: Filtering boxes for respirators
IPC: A62B19/00
Filed: 1926-11-17
Abstract: 281,857. Fernez, M. Nov. 17, 1926. Respirators.-A filter-box for respirators comprises a canister A, Fig. 1, containing chemicals and having an air-filtering appliance X wound around it. The appliance X comprises two superposed sheets B, 0 of paper or fabric spaced from one another by strips D along their edges and closed at one end C<1>. An elongated chamber is thus formed which is wound around the canister A, the convolution being separated by perforated peripheral strips E. The sheets B, C terminate at their inner ends at points G, F respectively thus providing ingress to the canister A through perforations A<1> therein. The opposite side A<2> of the canister communicates with the respirator. The canister A may be dispensed with, the sheets B, C being wound around a central tube and being impregnated with chemicals. In both constructions the inhaled air passes through the perforated strips E and through one thickness of filter material on its way to the respirator. To ensure even suction through the whole of the filter material the sheets B, C are coated with impervious material, such as cellulose varnish by spraying through a perforated plate, the perforations of which increase in number from the inner to the outer ends of the strips. As shown in Fig. 6 superposed filter layers B, C, centrally perforated, are joined to adjacent layers at their inner and outer edges respectively by spacing strips D<1>, D. The lowermost layer is imperforated. The layers are enclosed in a casing E having inlet apertures X and an outlet tube I communicating with the interior of the filter. The layers B, C may be connected by sewing or the like, without the spacing members D, D'. In this case they are spaced by a central rod abutting against a gauge screen in the top of the casing.

Title: Improvements in or relating to sheet feeding apparatus
IPC: B65H9/10
Filed: 1938-10-08
Abstract: 502,656. Feeding sheets. BACKHOUSE, H. T. Oct. 8, 1938, No. 29216. [Class 100 (i)] To ensure correct register of sheets at the front stops 12 on the layboard of a sheet-feeding apparatus a supplementary sheet impelling device is adapted to engage the rear edge of each sheet as it approaches the stops so as to give the sheet thrust in the feeding direction additional to that of the normal feeding means. As applied to a stream feeder in which the sheets are fed by tapes and running-in wheels 13 and under smoothers 17, and in which the rear edge of each sheet overlaps the front edge of the following sheet, the impelling device comprises a pair of pull rods 19 fitted with claws 31 for engaging the rear edge of the front sheet as the rods 19 are moved to the left by means of reciprocating rods 20 connected to levers 22 on a shaft 23 which is rocked by a connecting- rod 30, lever 27, and slotted crank 25 from a cam on the sheet-feeding apparatus. The rods 19 are spring-mounted and pivoted to adjustable blocks 32 on the rods 20, and after the sheet has been engaged by the claws 31, and the sheet registered, the rods are raised above the sheets on their return motion by means of pivoted switches 40, Fig. 2, which engage pins 46 on the rods 19. The pins 46 move under the switches when moving to the left, but on reverse movement the pins ride over the switches, which are adjustably mounted on rods 43. For dealing with short sheets the rods 19 can be reversed and effect a pushing instead of a pulling action. A modified form of impelling rod 50 is shown in Fig. 3, which is fitted on its underside with a plate 51 formed with two operating edges 52, 53 so that the rod can be used as a pull or push rod. Specifications 15397/10, 2724/11, and 114,510, [all in Class 100 (i)], are referred to.

Title: Process for the preparation of Silane Polycondensates
IPC: C08G77/00
Filed: 1966-06-29
Abstract: 1,154,850. Polyorganosiloxanes. SOCIETE INDUSTRIELLE DES SILICONES. 29 June, 1966 [29 June, 1965], No. 29228/66. Heading C3T. Polyorganosiloxanes are prepared by continuous hydrolysis of silanes. One or more silanes having three or four hydrolysable substituents are first dissolved in a polar solvent; this solution is then subjected to the continuous action of a hydrolysing agent so as to produce partial or complete hydrolysis in a single homogeneous liquid phase. The reaction time lies between 10 seconds and 10 minutes and the polycondensate formed is continuously separated. One or more hydrolysable silanes (which may have less than 3 or 4 hydrolysable substituents) may also be introduced into the homogeneous liquid phase before separating the condensate. They may be added in solution to the continuous liquid phase or may be hydrolysed before adding to this phase. The hydrolysing agent may comprise water or a substance capable of liberating water. The starting silane may be methyltrichlorosilane, trichlorosilane, vinyltrichlorosilane, phenyltrichlorosilane, tetrachlorosilane, methyldichloroacetoxysilane or methyltriacetoxysilane. Examples of the additional silane, which may be added so as to form a graft copolymer, are methyldichlorosilane, dimethyldichlorosilane, trichlorosilane, methyltrichlorosilane, vinyltrichlorosilane, phenyltrichlorosilane, tetrachlorosilane, methyldiacetoxysilane or methyltriacetoxysilane. The polar solvents used in the process may be ethers, ketones, halides, alcohol-ketones, alcohol-aldehydes, polyols, alcohol ethers or compounds containing one or more sulphur or nitrogen atoms. A minor proportion of non- polar solvent may be mixed with the polar solvent. Complete hydrolysis may be effected by using an excess (e.g. 6 times the stoichiometric quantity) of hydrolysing agent. Hydro lysis may take place at - 60 C. up to the boiling point of the reaction medium but is preferably carried out at ambient temperature. The homogeneous liquid phase may be treated, e.g. by neutralization, addition of more water, or by distilling off some of the residues, to cause a separation into two phases, one of which contains the polycondensate and the other the byproducts formed.
