Abstract: PCT No. PCT/SE94/01222 Sec. 371 Date Jun. 13, 1996 Sec. 102(e) Date Jun. 13, 1996 PCT Filed Dec. 19, 1994 PCT Pub. No. WO95/17636 PCT Pub. Date Jun. 29, 1995A cooling system of compact design includes redundancy and free cold source usage. The system includes two circuits for circulating coolant and heat absorbing medium, and two heat exchanges common to the circuits. The heat exchangers are combined to act on both of the circuits, so that inside air is cooled by cold liquid or by expanding coolant in a combined evaporator-air cooler, and the outside air is used to cool warmed liquid or condensed coolant in a combined condenser-liquid cooler. Free cold, that is, outside cold air, may be utilized when the difference in temperature between inside air and outside air is sufficiently great and the outside air is sufficiently cold. Liquid cooled by outside air in the combined condenser-liquid cooler and then heated by warm inside air in the combined evaporator-air cooler can satisfy the entire heat load. In other cases, the compressor system can provide cooling. The free-cooling system can serve as a redundant system for the compressor system.

Abstract: The invention relates to a method for determining connection quality, and a receiver in a radio system, the receiver comprising means for decoding a received signal by the Viterbi method by means of a trellis diagram comprising a group of state points, and means for calculating state transition values for the two possible transitions in each point of the diagram. To determine advantageously the quality of the connection between a transmitter and the receiver, the inventive receiver comprises means for calculating, in each column of the trellis diagram, the maximum values for both the transitions of the points in the column, for determining the absolute value of the difference of the calculated maximum values, and means for estimating connection quality by utilizing said absolute value.

Filed: 1996-12-12
Abstract: A process and an arrangement for controlling rock drilling on the basis of the pressure in the pressure duct for the drive motor of the drill rod. In the process, the pressure in the pressure liquid duct of the drive motor is measured during the rotation, when the drill bit is not in contact with the drilling rock, and the control is subsequently exercised during the drilling on the basis of the difference between the pressure value during the drilling and the pressure value at idle. In the arrangement, the rock drilling device incorporates a control unit, which measures the pressure in the pressure liquid duct of the drive motor when the drill rod rotates without contact with the drilling rock and stores this value in a memory and controls the rock drilling device on the basis of the difference between the pressure value measured during the drilling and the pressure value at idle. <IMAGE>

Inventor: MORWAY ARNOLD JESSE
Filed: 1960-01-12
Abstract: A lubricating composition comprises a lubricating oil, a minor proportion of a metal salt of a C1-C3 carboxylic acid and a minor proportion of a polyethylene resin.  The lubricating oil may be of animal, vegetable, mineral or synthetic origin, examples of synthetic lubricants being hydrocarbon polymers, diesters, complex esters, formals mercaptals, polyalkylene oxides and silicones.

Title: Photosensitive element with integral reinforcement
IPC: G03F7/004
Filed: 1974-01-11
Abstract: 1414103 Photohardenable material having reinforced photohardened layer E I DU PONT DE NEMOURS & CO 11 Jan 1974 [11 Jan 1973] 01335/74 Heading G2C A photo-sensitive element comprises a sheet of photohardenable material and a layer of photohardened said material, the layer containing continuous reinforcing material e.g. a fabric such as a marquisette fabric of stretched and heat-set polyester yarn. The open space of the weave of the fabric may be 3-20 times the closed space of the weave. The element may also comprise a removable cover sheet e.g. polyethylene terephthalate film coated on both sides with a vinylidene - chloride - alkyl acrylate - itaconic acid copolymer mixed with an alkyl acrylate and/or methacrylate polymer and on the side nearest the photohardenable material with a gelatine sub layer (see Ex I) on the side of the sheet remote from the layer and an external support film on the side of the sheet adjacent the layer. The photohardenable material may comprise (a) an organic polymer binder, (b) an ethylenically unsaturated compound containing 1-4 ethylenic groups, having a boiling point above 100‹C at normal atmospheric pressure, a molecular weight less than 1500 and capable of forming a high polymer by photoinitiated polymerization, and (c) an addition polymerization initiator activatable by actinic light. The photohardenable material may contain a polymerization inhibitor or a dye (see Ex II and IV). The photo-sensitive element may be prepared by embedding e.g. by calendering a continuous reinforcing material into a layer of a photohardenable material during or after forming the photohardenable material into a sheet and exposing the layer to actinic light to photoharden the layer while leaving the remainder of the sheet unhardened. The photohardenable material may be polyvinyl cinnamate, a polymer having chalcone and benzophenone type groups, or a combination of a polymer such as acrylic and methacrylic acid amide polymers, polymeric polyols or natural colloids with a light-sensitive cross-linking agent e.g. a metal dichromate, diazo compound or azide. In Example II the relief plate produced on exposure and development is post-exposed to further harden (polymerize) the photopolymer image and reinforced layer. Three subsequent photohardenable layers are laid on top of the photo-sensitive element of the invention and pressed at 150‹C for 1 minute at 700 kg/cm<SP>2</SP>, 1 minute at 1400 kg/cm<SP>2</SP> and 2 minutes at 2800 kg/cm<SP>2</SP> in Example III. This element is conditioned by holding in CO 2  for 6 days in Example III before hardening the layer containing the reinforcing material. The exposed and developed element may be used as a stereo master for moulding or printing and is tough and resists delamination.

Abstract: 972,141. Electric selective signalling. UNITED AIRCRAFT CORPORATION. Jan. 15, 1962 [Feb. 20, 1961], No. 1490/62. Heading G4H. [Also in Division H3] A switching circuit comprises a pair of diodes 10,12 connected back to back, at least one of the diodes being made conductive by a bias voltage connected to their common electrodes, switching and reference voltages being respectively supplied to their other electrodes. If the bias voltage is greater than the switching or reference voltages, one or other diodes, 10, 12 is conductive but both diodes become conductive, so as to connect a source 20 to an output terminal 28, only if the switching voltage at 38 is approximately equal to the reference voltage at 44. Selective impedance measuring system. Fig. 4 shows a voltage-sensitive distributer using a plurality of such circuits 46a-46d, having common input terminals 38 and arranged to select any one of a matrix of radiation-sensitive resistors 78. A different reference voltage is supplied to each diode 12 from a potential divider 102 supplied from a D.C. source 104, whilst a bias supply of higher voltage at terminal 82 is fed via resistors 36 to the common electrodes of each pair of diodes 10, 12. Each gate 46a-46d is opened only when the switching voltage at terminal 88 is made approximately equal to the reference voltage supplied to that gate so that the output of an r.f. oscillator 96, after amplification at 98, is fed to a selected Y co-ordinate line. A further gate of a similar set, 46e-46h is selected when the voltage fed to terminal 118 is equal to the reference voltage at the appropriate tapping of potential divider 112. Radio frequency current thus flows through the selected radiation-sensitive resistor 78, developing a voltage across a common load 124 indicative of the impedance of the selected resistor 78. This voltage is passed via an emitter follower 130 and an amplifier 148 to a diode rectifier 150. Errors due to spurious coupling via unselected resistors 78 are minimised by feedback via resistors 160, 162 to both sides of all resistors 78. Resonant circuits 86, 42, tuned to the radio frequency, minimise the interaction between R. F. and D.C. circuits,
