Title: Electrophotographic developer
IPC: G03G9/12
Filed: 1964-07-07
Abstract: 1,070,748. Xerography; development processes. COMMONWEALTH OF AUSTRALIA, DEPARTMENT OF SUPPLY. July 7, 1964 [July 11, 1963], No.28028/64. Heading G2H. A developer for use in chargeless developing of xerographic surfaces containing an electrical image, comprises an insulating carrier liquid in which a pigment is suspended, a dispersing agent for the pigment to create a finer suspension, and also comprises a further dispersion to said carrier liquid of a medium of charge polarity opposite to that of the said pigment, this medium having less electric charge than the pigment whereby the pigment develops a maximum image density and the second developer, as well as driving down more pigment, forms a background shield during development to lessen contamination of the background by pigment particles. In this xerographic system no corona charging is used, but the zinc oxide or other photo-conductive surface is darkrested for some days and acquires an attraction for positively charged toner particles. Positively charged areas are formed where light falls and the toner is there repelled; direct image reproduction is therefore possible. The developer components are:- (a) Carrier liquid; an insulating hydrocarbon. (b) Pigment of opposite polarity to the area to be developed; Carbon Blacks, Peerless Blacks, Monolite Trade Mark Blacks (ICI), Irgalit Fast Blue (Geigy). (c) Control coating to make the pigment of (b) have an opposite charge to the area being developed or increase its charge; vegetable oils may be linseed oil, Sunflower seed oil, Tung oil, etc.; mineral oils may be B. P. "Viscostatic" (Trade Mark) Motor oil, polybutyl methacrylate, Bitumen. (d) Dispersing agent; long oil alkyd resins such as Super Beckosol Trade Mark +1352- (Reickold Corp.), Rhodene resin, +PC2/70 (Polymer Corp). (e) Dispersion of opposite charge polarity to the combination of (b) and (c), or a control agent at opposite polarity effect to the one of (c) placed on the pigment; for use when (b) plus (c) is negative the mineral oil agents of (c), alcohols, low concentrations of strongly positive pigments, bitumen; for use when (b) plus (c) is positive, the vegetable oils of (c), low concentration of any long oil alkyd of (d) with negative pigments.

Title: Sustained release drug delivery devices
IPC: A61K9/00
Filed: 1976-07-06
Abstract: The device for delayed pharmaceutical release is used in an aqueous environment in the human or animal body. It essentially releases the pharmaceutical by diffusion. It displays an integral solid structure of such a shape and size that it can be introduced into the environment in which it is to be used and can be held there. It consists of a mixture which contains a non-ionic pharmaceutical, a polymer and, in addition, 0.1 to 15% by weight of a soluble substance with osmotic activity. The pharmaceutical has a solubility in water of from 200 to 10,000 ppm. The polymer is permeable to water and to the pharmaceutical, is insoluble in the aqueous environment at least for the duration of the pharmaceutical release and is impermeable to the soluble substance. The soluble substance is in the form of single depots which have a number average diameter of 1 to 250  mu m which are dispersed in the polymer so that they are surrounded essentially singly by a polymer layer. When the device is introduced into the aqueous environment, the depots absorb water and rupture the surrounding polymer layers. This results in a network of mutually connected pores inside the device. There is thus an in situ enlargement of the surface area on which the pharmaceutical can be released from the polymer to the environment. This in situ enlargement of the surface area increases the rate of release of the pharmaceutical from the device.
