Title: Improvements relating to the manufacture of articles of ceramic flat ware
Inventor: ROBINSON JAMES
IPC: B65G47/252
Filed: 1969-12-24
Abstract: 1285090 Turning and transferring articles on endless conveyers WEDGWOOD Ltd 19 April 1971 [24 Dec 1969] 62819/69 Heading B8A Apparatus for turning over ceramic articles between processing operations on a conveyer consisting of parallel wires 13 comprises a pickup head 24 connected by a tilt cylinder 22 and pick-up arm 21 to a shaft 19, the pick-up head 24 being moved through the conveyer wires 13 into engagement with the downward facing side of the article when the article interrupts a light beam emitted from a source 15a, a light responsive cell 15b transmitting an impulse to an actuator 18 comprising pistons (18b), Fig. 3 (not shown), whose reciprocatory movement imparts a rotational movement to the shaft 19, said movement bringingthe head 24 into engagement with the article, a vacuum connection having been established with the head 24. The head 24 and article are rotated about the shaft 19 as indicated by the positions A, B, C, the head 24 being aligned parallel to the conveyer for depositing the article thereon at position C by retraction of the tilt cylinder 22 under the action of a first cam (not shown) mounted on the shaft 19 and a second similarly mounted cam shuts off the vacuum to the head 24, thereby releasing the article on to the conveyer. The head 24 is then rotated in reverse to its former position. The apparatus may be positioned between two chambers in series in each of which there is a conveyer between which the apparatus transfers the articles, the articles being sprayed on their upward facing side in each chamber.

Title: Device for granulometric analysis of particles in fluids
IPC: G01N15/14
Filed: 1978-07-12
Abstract: A device for granulometric analysis of particles contained in fluids has a feeding channel 2 communicating with a receiving channel 4 by way of a nozzle 3. The ratio between the diameters of the nozzle and the receiving channel is in the range of 1/4 to 1/7. The receiving channel is provided with transparent windows 5, 6 through which light from a lighting means 7 is directed into the fluid in the channel. A light-sensitive means 8 receives light reflected from particles contained in the fluid and provides with its output a measure of the particle content. The axes of the feeding channel and the lighting means extend perpendicular to the receiving channel axis which is coincident with the axis of the light-sensitive means. The range of the ratio of the diameters mentioned above is found to provide a high accuracy of measurement. <IMAGE>

Patent GB-2072851-A (GB)
Title: Liquid level detector circuits
IPC: G01F23/24
Filed: 1980-03-12
Abstract: In containers such as tanks for in place cleaning purposes, it is often desirable to terminate the flow of liquid into or from the container at a pre-determined level. Circuits are known which produce an operation signal when a polar liquid reaches (or falls below) a pre-determined level. Problems arise because of turbulence which may lead to a premature operation signal and thus premature cessation of the flow of liquid, and because of foam at the head of the liquid which may have a similar effect. A liquid level detector circuit is disclosed which discriminates between three conditions at a probe, namely polar liquid, foam or air and ensures that turbulence does not result in the generation of an operation signal by virtue of a delay means T in the circuit. <IMAGE>

Title: Improvements in motor- immersed fuel pumps
IPC: H01R39/04
Filed: 1980-07-22
Abstract: The copper wire for the armature coil (14) of a motor-immersed fuel pump for use in the fuel supply system of a vehicle, the brush lead wires (19) if they are made of copper, and likewise the connection leads (20, 21) are coated with a petrol-proof material, such as epoxy resin or other organic adhesive.

Patent GB-2077592-A (GB)
Title: Sterilization of bandage materials
IPC: A61L2/20
Filed: 1981-06-12
Abstract: Bandage materials comprising aqueous, transparent, hydrophilic organic gels in sheet or band form may be sterilized by contacting the gel with ethylene oxide until all microorganisms have been killed and subsequently eliminating free ethylene oxide from the gel to a level showing no toxic effects. Any ethylene oxide not completely removed from the gel combines with the water therein to form adducts. Elimination of ethylene oxide may be effected by warming the gel, applying a vacuum, by allowing the gel to remain at room temperature for a long period, or by combinations of these methods. The gel during sterilization may be sealed in one or more envelopes of foil material permeable to ethylene oxide and the package sterilized as a whole.

Title: Light emitting diode assembly
IPC: H01L33/08
Filed: 1981-06-24
Abstract: An assembly of monoliths 16 containing light emitting diodes 18 (LED's) yields a relatively long array of LED's with high light density and a contiguous set of light centers. Each monolith has two parallel rows of light emitting diodes, and the light emitting diodes of one row are laterally offset towards to the light emitting diodes of the adjacent row to give a higher light density than would be the case if they were not so offset. A fiber optic cover 24 is placed over the exposed surfaces of the LED's to limit escape of light and to protect the LED's from damage. A gel 28 having a relatively high refractive index is applied between the LED's and the fiber optic cover. The assembly may be used in apparatus for electronically recording data using a xerographic machine. <IMAGE>
