Title: Colour photographic multi-layer material
IPC: G03F/
Filed: 1961-07-14
Abstract: 923,045. Colour photographic material. AGFA A.G. July 14, 1961 [July 16, 1960], No. 25645/61. Class 98 (2). Multilayer material as for formation of cyan, magenta and yellow partial images comprises at least one assembly of two layers sensitized to the same region of the spectrum but of different sensitivity containing colourless couplers for formation of the same colour, the more sensitive of the layers producing a coloured image of lower colour density than the less sensitive layer. Increase of total sensitivity with avoidance of undue coarseness of colour grain, particularly for exposure material, results. Example 1 provides full description of formation of the red sensitive double layer, using about four times the quantity of cyan coupler in the fine grain emulsion which is cast next to the support as that for the adjacent highly sensitive emulsion, and of step-wedge exposure, processing, sensitometric and granularity measurement results. Ten further examples directed to one or other of the three double layers are generally similar but include use of different couplers for the same colour instead of different quantity. The description states that coloured couplers as of Specifications 599,377 and 698,046 may be added to the layers. Specifications 458,400, 541,589, 786,592, 818,687, 861,138 and U.S.A.

Title: Improvements in anti-vibration and shock absorbing devices
IPC: F16F9/19
Filed: 1924-10-28
Abstract: 246,571. Steuart, F. G. Oct. 28, 1924. Fluid - friction vibration - dampers. -In shock-absorbing devices applied between the spring b and the frame k of a vehicle and of the kind in which relative movement takes place along an inclined path, the apparatus employed is of the kind in which the interior of a cylinder a and hollow plunger h, i is divided into three chambers by a piston w and a valve y. The piston w is carried by a small piston rod t secured to the end of the cylinder a, this piston rod being provided with a central hole and with radial holes u to connect the upper and lower chambers. Small holes y may be provided in the piston. The valve z is pressed on to its seat by a spring 2, and a small leak hole is provided in the valve seat. The air space above the liquid in the hollow plunger is provided with a filling opening having a stopper l with a small vent hole. The annular space n forms an air cushion and a one way valve o may be provided to allow oil which may leak into the space n from the lowest chamber to escape into the upper chamber. When the spring b and the cylinder a move upwards relatively to the vehicle frame, fluid passes from the lowest to the intermediate chamber past the valve z while a smaller quantity leaks past the piston w or through the hole y into the upper chamber, the resistance to this upward movement being small. Downward movement of the cylinder e closes the valve z so that fluid in the intermediate chamber can flow into the lower chamber only through the hole 3 and through the hole y, upper chamber, central hole in piston rod t, and radial holes u. In a modification, the apparatus is fixed in the vehicle frame and pivoted to the spring and the area of the openings in the small piston rod t may be adjusted from the outside. In a further modification, the vehicle spring is connected to the plunger and the valvular device is arranged above the piston on an extension of the small piston rod. The piston rod t may be connected to the plunger, the piston w being then slidable in the cylinder a.

Abstract: 1323990 Transistor logic circuits INTERNATIONAL BUSINESS MACHINES CORP 5 June 1972 [26 June 1971] 26114/72 Heading H3T An inverter consists of three F.E.T.s TD, TX, TA and resistance R, which could be a further F.E.T., connected together as shown so as to respond to inputs D, A and to charge a capacitance CL. When input D turns on TD the output O charges to V ("1") through TD, unless A holds TA also on; when D holds TD off, the level at D is transmitted through TX to hold output O at this level ("0"). Further F.E.T.s TB, TC may be connected in parallel with TA (Fig. 3, not shown) or in series therewith (Fig. 6, not shown) to constitute a NOR and a NAND gate respectively. In a further embodiment (Fig. 7, not shown) a capacitor C across TD acts to hold TX conductive for a time after D has turned on TD; thus the charging of O by V through TD is supplemented by a current from D through TX, D now also being at the "1" level. If CL should be immediately discharged by TA, TB however, the fall in voltage at O increases the drive to TD to discharge C. The application of the NOR circuits as a decoder for addressing a storage matrix is described, in which the output O constitutes a word line select pulse in response to address signals at A, B, C and a higher order address signal at D without the need for critical timing of the A, B, C signals with respect to the D signal.

Title: Method and composition for the treatment of hydrocarbon fuel gases
IPC: C07C7/12
Filed: 1961-07-19
Abstract: Hydrogen sulphide is removed from hydrocarbon fuel gases by contacting the gas in an alkaline environment and in the presence of moisture with a finely divided metallic element, capable of combination in more than one valence state and having an atomic number in the range 23-50.  The preferred metal is iron.  Other metals include cobalt, nickel, chromium, vanadium, manganese and tin. Oxygen may also be present, and may be provided by mixing air with the fuel gas for example in an amount of at least 0,025 cu. ft. per cu. ft. of gas.

The alkaline environment may be provided by a water-soluble alkali metal salt, for example the carbonate, especially sodium carbonate. Preferably the average size of the wood shavings is greater than the average size of the iron and alkali metal carbonate particles.  The composition may be divided into substantially equal portions, placed into a plurality of vessels connected in series, and fuel gas is then passed through said vessel, the position of each of said vessels being successively changed relative to the position of the vessel into which the fuel gas first enters, at predetermined intervals, preferably about 12 hours.

Title: Method of producing coating compositions from epoxide resins and unsaturated triglyceride oils
IPC: C08L63/02
Filed: 1952-10-20
Abstract: An epoxide resin which is a polyether derivation of a polyhydric phenol with terminal epoxide groups and intermediate alcoholic hydroxyl groups and which may be prepared from a polyhydric phenol by reaction in alkaline solution with epichlorhydrin, is heated with a drying oil at 450-580 DEG  F. until a homogeneous blend is formed. The products are soluble in hydrocarbons such as xylol, or naphtha or mixtures thereof to yield coating and similar compositions.  If desired, small amounts of alkaline catalysts may be added to the reaction mixture.  The proportion of epoxide resin in the mixture may vary from 5-90 per cent.  In examples an epoxide resin prepared by reacting epichlorhydrin with biphenol in presence of sodium hydroxide was reacted with dehydrated castor oil and the product dissolved in a hydrocarbon mixture or in xylol to yield a coating composition. Diethylene triamine may be added as a curing catalyst.  The dehydrated castor oil may be added in stages with some heating in between.  In the example, the dehydrated castor oil is replaced by soya bean oil.  Other examples describe the use of an epoxide resin made by heating the one referred to above with bisphenol. The reaction may be performed in a closed kettle with an atmosphere of carbon dioxide, in an open kettle or under reflux. Linseed oil is also referred to as a suitable unsaturated triglyceride. Specifications 675,165, 675,166 and 675,167 are referred to.
