Title: Plate-form building component for dividing walls, etc. - automated control of location and quantity of foam filling
IPC: B29C44/18
Filed: 1975-03-21
Abstract: A building component for dividing walls, etc. is produced by laying a flat surfacing plate horizontally and arranging on it, reinforcements in the form of ribs and/or other structures together with technical installation details, and filling in the cavities between with a mass of synthetic foam. The filling is applied by one or more nozzles directign jets of foam as the first relative motion between the assembly and the nozzles takes place, the flat surfaces being coated first of all, whilst means are provided to increase the quantity of foam in the corners between the plate and the reinforcement or constructional details, and to prevent the surfaces of these details being covered with foam. The quantity of foam applied in the corners is increased, either by speeding up the flow through the nozzles or by slowing down or stopping the motion of the plate. Alternatively the nozzles may approach the critical points or be tilted in their direction, whilst as the nozzles approach the surface of the constructional details, the flow is either cut off, or gas jets divert the flow was required. Automates the process of applying the filling to the loosely arranged components.

Title: Screw thread forming die production process - applies shaping tool to generate different pitch between other grooved sections
IPC: B21H3/02
Filed: 1975-06-19
Abstract: The process is for the production of screw thread forming dies. A rotary shaping tool is formed, with first and second groups of alternate lands and grooves of the same pitch on a cylindrical surface. The shaping tool is so applied to the work as to form between the two groups an additional land (8) or groove of different pitch. The tool thus produced is then used to produce the thread-forming die, or an intermediate shaping tool to produce the latter. The additional land or groove can be either of coarser or finer pitch than the rest, being produced in two parts.

Title: Thin walled metal pipe coated with plastics - applied by turbulent air in sub-atmospheric duct preventing powder escape
IPC: B05D7/14
Filed: 1975-09-03
Abstract: The parent patent describes a method of coating a continuously moving, thin-walled metal pipe with plastics powder by high-speed, turbulent air entrainment of the powder into the coating chamber: the temp. of th pipe entering the chamber being sufficient only to cause preliminary fritting of the powder; the frit being melted in an immediately following stage to form the coating. The addn. describes an appts. for the process, comprising a cylindrical chamber, maintained at sub-atmospheric pressure by a suction chamber and blower, an inlet pipe for powder-air mixt. adjacent to the nozzle-shaped mouth, and a cyclone for sepg. powder from the extracted air and recycling it to a fluidising chamber with injector. No powder escapes to atmosphere; fully automatic operation is possible and it is much faster and safer tahn electrostatic coating.

Title: Photosensitive solid-state electronic element with dielectric layer - has anode-cathode flow modified by photon induced field
IPC: H01L31/113
Filed: 1976-07-23
Abstract: A photosensitive solid state electronic device has its anode cathode current modified by photon-induced alteration of the electrical condition of a dielectric layer or layers, in which the modulating field is developed. The device comprises a first and a second electrode in or on the semiconductor body, through which a channelled stream can flow in a zone of the body neighbouring on one of its surfaces. There is a dielectric layer on at least part of the surface, and on this dielectrical layer photosensitive material and an auxiliary electrode neighbouring on the photosensitive material. The photosensitive material is selected so as to cause charge injection in the dielectrical layer on illumination, and the preadjustment electrically of the device so as to alter the electrical condition of the dielectric layer and to influence the channelled flow on the semiconductor body. The photosensitive material is chosen so as to excite a potential on the auxiliary electrode which serves to inject carriers into the dielectric layer; this potential arising from the photo-voltaic effect. The charge injecting material is chosen from among a wide range of substances including phthalocyanine, pinacyanol, cryptocyanine, crystal violet, methylene blue, etc. etc. If forms a layer on the dielectric layer between 0.025 and 2 micrometres thick and comprises a photosensitive substance embodied in an inert matrix of synthetic or polymer material. Is applicable to field effect transistors and field effect diodes, giving considerably improved working. Instead of a photoconductive layer, a coating of a charge injecting photosensitive material is applied on or in a dielectric layer. Improved memory systems using optical modulation can store data at greater density, and the device can be used for example in optical pattern recognition systems using optical cables.

IPC: B27N3/28
Filed: 1984-12-18
Abstract: Extrusion of a mixture of vegetable bits with a binder, particularly wood chips with a weather-resistant binder, involves precompressing in a compression chamber of an extrusion press the mixture by a compression stroke transverse to the extrusion axis, the compression stroke being delivered by at least one precompression piston. Prior to the precompression elongated bits of the mixture are acted on by an orienting influence so that the elongated bits are deposited substantially parallel to the extrusion axis. The outer layers of the mixture are compressed with a reduced precompression ratio so that the bits oriented prior to precompression remain fixed in position during the subsequent extrusion stroke. Preferably the elongated bits in the mixture are oriented by free fall of the mixture through a plurality of upright, thin-walled bars of approximately equal height positioned above the compression chamber during filling of the extrusion apparatus by a mechanical hopper moving to and fro over the bars continuously.
