Patent GB-2217655-A (GB)
Title: Positioning workpieces, for example in screen printing machines
Inventor: SZARKA SANDOR
IPC: B41F15/08
Filed: 1989-03-02
Abstract: Accurate positioning of a support plate 10 with respect to a fixed head 18 in ensured by positive locators at opposite edges of the plate which are brought into the operative position at a suitable stage of the workcycle. The system is particularly suited to multi-station screen printing machines with the plates 10, carrying pallets 50 on which workpieces are deposited, being intermittently indexed by drive chains 12 along track 11 to each printing station in turn. The plates are resiliently and non-rigidly mounted by means of grommets (43, 44) and pads (49), Fig 2, on the chain and track, and are registered accurately by interaction of locators when the printing head 18 is lowered to engage the workpiece. Thus, opening 22 in inner locator bracket 20 co-operates with cam followers 16 at edge 13 of the plate, whilst notch 23 at opposite edge 14 co-operates with roller 24 on a member 25 pivoted into position at the same time as the head 18. In another embodiment, Figs 7 to 9, the movement of the locators is independent of the movement of the print head. <IMAGE>

Patent GB-909869-A (GB)
IPC: H01L21/00
Abstract: 909,869. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. June 3, 1959 [June 9, 1958], No. 18920/59. Class 37. A silicon body into which an impurity is to be introduced is subjected to an atmosphere including the impurity in the vapour form for such a time and at such a temperature that a layer of glass is produced on the surface of the body with an impurity diffused layer beneath the glass; the glass is then removed by etching and the body heated so as to cause the impurity to diffuse further into the body. The Specification states that the concentration of the impurity measured after removal of the glass is found to be a constant substantially independent of both vapour pressure and temperature of the silicon. In the arrangement shown in Fig. 1, the silicon body is mounted on a base 12 with a closely fitting lid and made of fused alumina or platinum and is placed in a silicon furnace tube 11 through which flows an atmosphere which is interchanged with that in the box. Where boron is the impurity the body is first etched and plated or may have an oxidized layer produced on its surface as described in Specification 809,644. Boron trioxide is plated in the bottom of the box and the silicon body 13 placed on a platform 15. The box restricts the volume in which the source material vaporizes so as to provide an excess of impurity in contact with the silicon. The diffusion step may be conducted at a temperature in the range 700 to 1300 C. At temperature below 1150 C. the atmosphere may be an inert gas, e.g. nitrogen argon or helium; at temperatures above 1150 C. oxygen must be introduced to prevent the silicon from pitting. A dark deposit which sometimes occurs may be avoided by using a mixture of boron trioxide and silicon dioxide. The resultant body has a layer in which the impurity predominates and a layer of glass. The glass is removed by means of an etchant which does not attack the silicon, e.g. hydrofluoric acid and is then placed on a platform in a furnace of the type described above, and heated for a time and temperature determined by the degree of diffusion required in an atmosphere of pure oxygen or of oxygen and an inert gas. A temperature of from 700 to 1350 C. is suggested but 1100 to 1300 C. is preferred. In an arrangement for depositing phosphorous (Fig. 2) from phosphorous pentoxide in a container 29 kept by a heating coil at 275 to 230 C. a gas containing the phosphorous vapour flows over the silicon 22 which is maintained at from 700 to 1300 C. The Specification indicates the possibility of using antimony. Whatever the impurity it must be capable of forming a glass with silicon. If the impurity source is not an oxide either pre-oxidized silicon or an oxygen atmosphere must be used. Specification 816,799 also is referred to.

Title: Acoustic leak detection method for liquid storage tanks
Inventor: HILL CHRISTOPHER DAVID
IPC: G10K11/24
Filed: 1992-08-19
Abstract: The method is performed by affixing an acoustic sensor to an exterior surface of the tank under test. The pressure in the tank is then increased or decreased so that the pressure in the tank is not atmospheric and there is a differential pressure across the wall of the tank. Air is caused to flow through any hole that exists in the tank wall and the acoustic sensor picks-up the sounds generated by air flowing through the hole. The sensor can be attached to an elongate element which is itself fixed to the tank. The use of an elongate sound transmitting element, eg a ribbon, can be applied to other forms of testing. <IMAGE>

IPC: G01V1/52
Filed: 1993-11-24
Abstract: A downhole sound source, especially for the oil industry, uses the flowing drilling liquid (mud) to move a sound generating member to generate sound by mechanical contact. In one embodiment a rotor 4 having paddle blades 5 is adapted to be rotated in a direction marked by an arrow 7 by drill mud flowing in a direction marked by an arrow 6. The rotor rests against an annular dolly 2, which is attached internally to a drill string 1. The dolly is provided with notches 3 adjusted to corresponding notches 3' on one end of the rotor 4. When the rotor 4 is rotated, the notches 3, 3' will generate sound waves which are transferred to the drill string 1 and further to the formation wherein drilling is taking place. In other embodiments, a rod-shaped spring (10, Figs.3, and 4, not shown) attached to a plumb (11) is oscillated by flowing drilling mud to strike a sleeve (5), and a motor (14, Figs. 5 and 6, not shown) is driven by the drilling mud to rotate a resilient arm (16) engaging a toothed rim (13). <IMAGE>
