A dressing for wounds comprises an absorbent substrate having secured, to a portion or portions of a surface thereof, a non-absorbent film-facing with openings through which wound exudate may pass to the absorbent substrate and having a wound-contacting surface modified so that the surface tension of the wound-contacting surface is higher than the surface tension of wound exudate, whereby wound exudate which contacts the filmfacing wets the film-facing and tends to spread laterally over the wound-contacting surface of the film-facing. The modification of the wound-contacting surface of the film-facing may be effected by chemical treatment, and especially by coating the wound-contacting surface with a layer of surface active agent. Alternatively, the sunfarx active agent, if of the type which will migrate to the surface of a film upon aging, may have been incorporated into the film-facing itself; examples of such surface active agents are the anionic surfactants used in the emulsion polymerization of vinyl monomers, for example vinyl chloride. The absorbent substrate, which may be fibrous, is optionally provided with a backing sheet on the surface thereof which not adjacent the .film-facing. The film-facing, the openings in which may be semicircular in shape, may be of metal or plastics material, for example polyethylene or polyvinyl chloride. The surface active agent may be a hydrophilic surfactant or a lipophilic surfactant, and examples of each class are given; it is preferred to use a mixture of a hydrophilic surfactant and a lipophilic surfactant.

Abstract: 1,079,977. Polarographs. IMPERIAL CHEMICAL INDUSTRIES Ltd. April 25, 1966 [Jan. 23, 1965; May 14, 1965], Nos. 3195/65 and 20484/65. Heading GIN. In order to avoid undesirable fluctuations in the record output of a dropping mercury polarograph, the mercury drop is dislodged from the dropping capillary at a selected time before the end of its natural life and the mains supply to the recorder is switched off except for a small Tast interval once per cycle prior to dislodging the drop. In one embodiment, a synchronous motor drives a horizontal cam-shaft having two angularly adjustable cams. One cam (A) dislodges the mercury drop by slowly displacing the capillary against the action of a spring and then suddenly releasing it. The other cam (B) operates a microswitch in the mains supply circuit of the recorder. Two interchangeable cams (B) may be provided having respective different lengths of raised portion for respective different Tast intervals. The cams may be marked with angular scales to facilitate adjustment. The speed of the motor is preferably such that one revolution of the cam-shaft is completed in a time just less than the natural life time of a drop. To minimize transmission of vibrations to the drop from the motor, the motor may be mounted on rubber blocks and the dropping capillary in a soft silicone rubber tube. In an alternative embodiment, a multi-vibrator and relays replace the cam arrangement.

Filed: 1939-04-24
Abstract: 530,676. Sheet conveyers. STEVENS, A. H. (Davidson Manufacturing Corporation). April 24, 1939, No. 3313/40. Divided out of 530,970. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1939] [Class 100 (i)] A conveyer for sheets or other articles is described in connection with a folding machine as described in Specification 530,970 and is constructed so that the sheets can be conveyed by inclined conveying devices which can be set so as to register against either of two parallel gauges, and the sheets can be turned clockwise or counter-clockwise through 90 degrees during their passage along the conveyer. Two conveyers 3, 4 are shown in Fig. 1 arranged between the first and second, and second and third buckling folder devices. The folded sheets pass to a conveyer 7 connected to the machine frame 1 by means s of forked members and pins and by spring-pressed pins engaging holes in the frame. The folded sheet passes from the first folder and is' scored by rollers and if a second fold is desired, is then advanced over a table 91 by a narrow conveyer belt 95 which is mounted on rollers 96, 97 mounted in bearings 136, which can be set so that the belt inclines towards an upper registering gauge, or a lower one 115 as shown in Figs. 2 and 9. The gauge 115 forms part of a guide device, Fig. 9, detachably secured to a bar 105, and it may be replaced by a similar device attached to the upper end of the bar. It comprises a deflector 156 to prevent crumpling, and the folded sheet passes over a plate 114 and under a plate 117 which causes the front edge of the folded sheet to engage a projection 116 which halts the lower corner of the sheet so as to cause the sheet to turn through 90 degrees before engaging the gauge 115. The forwarding and turning of the sheet is assisted by means of a pressure strip 101, Figs. 1 and 8, fitted with openings to receive balls 107, and a spring-pressed roller 124 mounted in pivoted arms, and arranged near the projection 116 so as to assist the turning movement. When the belt 95 is arranged as in Fig. 2 the sheet turns counter-clockwise, but clockwise turning is effected when the upper edge of the sheet is registered. The twice folded sheet may be delivered direct to a delivery device 7, or may pass to the feed table 4 of a further folding device.
