Title: Liquid cooling of electrical apparatus
IPC: H01L23/42
Filed: 1976-04-26
Abstract: 1514601 Semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 26 April 1976 [27 June 1975] 16810/76 Heading H1K The cooling of semiconductor chips immersed in a volatile coolant (e.g. a fluorocarbon) by nucleate boiling is improved by drilling recesses of predetermined size and shape in the surface of the chips with the aid of a high energy beam to provide bubble nucleation sites. As described the recesses, formed by pulsed laser or electronbeam machining, preferably have a mean diameter, in planes parallel to the surface of between 3 and 15 Á and a length to mean diameter ratio between 2 and 4, and are surrounded at the surface by a raised lip. Such recesses retain sufficient vapour when each bubble becomes detached to nucleate a further bubble. They may be uniformly distributed over one exposed face and the edge surfaces of the chip, confined to or concentrated in areas where heat generation is greatest, or arranged along the edges or one edge of a wafer face. When the wafer is arranged vertically in the coolant with such an edge lowermost bubbles generated there in rising over the wafer face tend to recharge with vapour exhausted recesses and naturally occurring nucleation sites. In a typical embodiment, Fig. 8, a matrix of silicon chips 10 face bonded to common substrate 12 have different patterns of aperture appropriate to their cooling needs. To avoid hysteresis caused by temperature cycling individual heaters provided below each chip or a common heater 20 below the matrix has a surface provided with nucleation recesses preferably vertically aligned with those on the chips. These heaters are energised to maintain a flow of bubbles for recharging the chip nucleation sites when the chips are inoperative and switched off when they are functioning.

Title: Display apparatus incorporating a gas discharge panel
IPC: G09G3/28
Filed: 1970-04-09
Abstract: 1,274,639. Matrix displays. INTERNATIONAL BUSINESS MACHINES CORP. 9 April, 1970 [26 May, 1969], No. 16830/70. Heading G5C. A display apparatus incorporating a gas discharge panel of the type having a first and second plurality of conductors spaced apart and arranged to form a matrix of cross-points includes first means 12 for applying a sustaining voltage to the conductors, the sustaining voltage being insufficient to excite a discharge but sufficient to maintain a discharge at a crosspoint, and second means 14 for establishing an electrical discharge externally of the panel adjacent to a selected cross-point to excite a discharge thereat. A sinusoidal sustaining voltage A is applied by generator 12 to the panel 10 and to a differentiating circuit 20 which applies a spiked waveform B to clipping circuits 22 and 24 to produce waveforms C and D of positive and negative spikes. The negative spikes are converted to positive spikes by an inverter 26. The two sets of positive spikes together with voltage from a source 16 are applied to AND circuits 28 and 30 respectively which are connected to respective gate circuits in the stylus 14 controlled by "write" and "erase" buttons 32 or 34. Waveform E indicates the manner in which positive spikes superimposed on the sustaining voltage by applying the stylus 14 to the panel produce write and erase voltages which occur on the positive and negative peaks respectively of the sustaining voltage. It is also possible to provide a stylus which produces a positive write voltage and a negative erase voltage both of which operate on the positive peaks of the sustaining voltage. A further alternative form of stylus (Fig. 3, not shown) has a single on-off button and has in its tip a photodiode which is shielded during the writing operation and is illuminated by light from the display panel to act as a switch when erasure is required. In a more sophisticated circuit (Fig. 4, not shown) the sustaining generator 12 is connected to the individual X and Y conductors of the panel through X and Y pulsers which are connected through an address logic circuit to a computer. The X and Y conductors are also connected to sensing circuits to feed information back to the computer.

Title: Upholstering material made of rubberised fibres and process for its production
Filed: 1932-06-16
Abstract: In a process for making shaped upholstering material by coating animal, vegetable or mineral fibres, for example horse-hair, sea-weed, cotton, artificial silk or artificial horse-hair, with rubber dispersions such as latex, the fibres are subjected to a preliminary treatment with liquids which wet the fibres and effect coagulation of the latex, preferably before the fibres are placed in the mould.  After treatment with the coagulant and drying the fibres may be loosened by carding, the loose condition being preserved by providing the wire-basket mould with horizontal and vertical wires or rods.  A suitable dispersion comprises rubber latex, sulphur, transformer oil, paraffin wax, a vulcanization accelerator and an antioxidant.  The preliminary treatment may be effected with a single liquid for example calcium chloride dissolved in a mixture of benzol and methyl alcohol or two solutions may be used, for example benzene or an organic sulphonic acid followed by a solution of a coagulant. After treatment with the latex, excess is removed, for example by shaking and the product dried and vulcanized.

Title: Method of protecting metals in aqueous media from corrosion and fouling
IPC: C23F13/02
Filed: 1957-05-31
Abstract: 825,184. Preventing fouling and corrosion. PETROCOKINO, D. D., and RACLOT, B. May 31, 1957, No. 17293/57. Class 123(1) Metal surfaces, for example, the hulls of ships, water heater apparatus or refrigerator plants in contact with aqueous media, are protected from corrosion and fouling by organic deposits and growths by connecting the negative terminal of a pulsatory direct current source and one terminal of an alternating current source to the structure to be protected and connecting the other terminals to an electrode immersed in the medium and spaced from the structure. The electrode may be constructed from stainless steel, iron-silicon alloy, cupro-nickel alloy, platinum-palladium alloy or graphite. The direct current supplied is sufficient to ensure a current density of between 10 microamperes and 10 milliamperes per square metre of surface at a voltage of from 24 to 350 volts. The alternating current is supplied at a power rating of about one-fifth that of the direct current at voltages either below 50 volts and at frequencies less than 50 c.p.s. or at voltages about 1,000 volts and at frequencies greater than 1,000 c.p.s. In installations such as condensers, water-heaters or refrigerators the electrode is secured to the wall of the apparatus. For ship protection the electrode may be of the "drag" type which is streamed behind the vessel whilst sailing. In operation, which need only be of intermittent character in which the current is on for 48 hours and off for not more than 10 days, a corrosion protecting layer of hydrates, hydroxides, colloids &c. is built up on the surface and the growth of animal cell particles thereon is prevented by the electrophoretic attraction of such matter to the electrode.
