Abstract: In a desensitizing ink for the wet offset printing of a given area of the acceptor surface of a duplicating set containing an alkoxylated nucleophilic compound, preferably having a molecular weight lying in the range of from 2000 to 4000 and having a hydrophilic-lipophilic balance (HLB) of from 3 to 6, emulsified water is added to the mass of ink. This rapidly forms a fine stable emulsion of water in the ink which is favorable for continuous wet offset printing.

A roller bed comprises aligned rollers, each of which is divided into two separate frustoconical members 1a, 1b, Fig. 2, arranged one on each side of the path of travel of workpieces 7, e.g. tubes issuing from a tube drawing installation, each member being mounted on a lever 3 which is rotatable about an axis 3c, and gable-end, roof-shaped members 8 being provided between the rollers. As shown, the members 1a, 1b are freely rotatable but they may be driven. The levers 3 are selectively movable by rods 4, Fig. 1, connected to doubleacting rams 5 and adjustable by turnbuckles 4a, 4b. In operation, the workpieces 7 are discharged to one or other side of the roller bed by movement of the appropriate levers 3 to lower either the members 1a or the members 1b, the workpieces rolling down the inclined surfaces 8b or 8c of the members 8 to a receptacle which may be formed as a conveyer extending transversely of the path of travel of the workpieces 7 on the roller bed.

Title: Electro-hydraulic control device
IPC: F15B13/043
Filed: 1973-01-02
Abstract: 1384180 Hydraulic control circuits ROBERT BOSCH GmbH 2 Jan 1973 [5 Feb 1972] 269/73 Heading F1P In a control circuit in which a valve 41, Fig. 1, is moved by a pilot control device 12, fluid-flows from a reservoir 23 through a supply line 18, lines 26, the valve 41 and back to the reservoir through return lines 19, 21 when valve 41 is in the neutral position shown, and also charges an accumulator 31 through a line 28 and a reducing valve 33. The accumulator is connected to the pilot control device through a line 36. In operation, if a solenoid valve 51 is closed to isolate the pilot control device 12 from the accumulator 31 fluidflows round the lines 26, 22 without restriction. If-valves 51, 53 are actuated, chambers 48, 49 of the pilot control device are connected to the accumulator 31 by line 36, and slide valve 41 is moved to the right, making connections to the load. At the same time the accumulator is charged through a non-return valve 32 and the pressure reducing valve 33, as soon as the accumulator pressure drops below that at which the reducing valve 33 is set and pressure in circuit 26 is higher. To move the valve 41 to the left, solenoid valves 51, 52 are actuated so that pressure from the accumulator is supplied to the chamber 48. Fig. 2 shows an alternative circuit for controlling the pressure in the accumulator 31. If the latter is fully charged, pressure in chamber 74 will retain valve-member 73 against a spring 72 in a position in which a control duct 69 is open. Fluid therefore flows from circuit 26 through duct 69 to duct 21 and the pressure drop at throttle 71 pushes hollow member 64 against spring 66 into an operative position and the circuit 26 is opened with the band 67. If accumulator pressure drops below the minimum control pressure, valve-member 72 will close control duct 69 and pressure drop at throttle 71 is eliminated. This closes the circuit 26 so that the pressure therein is sufficient to charge the accumulator again. Screw 68 provides adjustment of the position of member 64. Fig. 3 shows an alternative construction of valve 61 which produces a constant pressure drop at the throttle 71 whatever the flow in the circuit 26, Fig. 4 (not shown), illustrates a slightly different arrangement of valve 61.

Abstract: 1,105,221. Convecting. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. 5 Jan., 1966 [6 Jan., 1965], No. 512/66. Heading H2F. In a high voltage direct current power transmission system the two A.C. systems KW and V have different phase numbers. As shown the system KW is a four phase generator connected to a rectifier station GR. The system V is a three-phase consumer network connected to the inverter WR. The stations are linked by cables K which have earthed sheaths and which include smoothing chokes DR. Possible modifications are: (a) more than one cable each for the " go " and " return " paths; (b) both " go " and " return " paths in a single cable; (c) earth return. Since the two A.C. systems have different phase numbers, the peak value of the A.C. ripple on the transmitted D.C. is limited, and hence cable losses are reduced.

Title: Manufacture of cushions
IPC: B29C51/08
Filed: 1975-01-07
Abstract: 1466531 Moulding foam filled cushions J SANSON 7 Jan 1975 [15 Jan 1974 10 April 1974] 570/75 Heading B5A Foamed cushions having a cover of a cloth exhibiting a degree of retraction after stretching are made by preforming a cloth using a frame which allows inward slippage of the cloth without elongation, terminating the preforming at a point before the peripheral contraction of the cloth is so great as to cause wrinkling, fixing the periphery of the cloth against further contraction, peripherally clamping the cloth over a vacuum mould, drawing the cloth into the mould and casting and curing a foamable resin within the drawn cloth whilst still in the mould. In this way the final vacuum forming step involves only little elongation of the cloth and thus a minimum of subsequent retraction and wrinkling after the foam has cured. For each cloth to be used the "maximum peripheral contraction coefficient"-that is to say the point beyond which wrinkling occurs-can be determined by drawing the cloth under vacuum through a circular clamp into a mould. In a first embodiment, a cloth covered by an elastic plastic layer is drawn by a plug 3 through a clamp 2 which allows slippage. The drawing is terminated and heating elements 5 in the clamp actuated to fix the periphery of the drawn cloth by welding. The thus formed preform is then clamped over a vacuum mould, drawn into the mould and filled with cast in situ foam. Preforms may be made on a production line basis from a web 17 intermittently drawn by rolls 25, 26, 27 between the members of a clamp 2. The web is drawn by a plug 3 after which a knife 22 is actuated to sever the preform from the web whence it falls on to a stack of previously drawn preforms. In another embodiment (see Figs. 10 and 12) a preform is vacuum formed from a cloth 1 held over a vacuum mould. The cloth is peripherally clamped between frame members 2a, 2b each having slots 30 directed towards the geometric centre 0 of the frame. A needle 33 projects into each slot to engage the cloth and is slidable along the slot against the action of a bias spring 34. The degree of travel of each needle in each slot can be arranged, by manipulation of stop 35a, so that the "maximum peripheral contraction coefficient" of the cloth being used is not exceeded. The cloth may be of nylon and preferred foam is polyurethane.

The device comprises means whereby a lifting movement is imparted to a member 55 firstly to relax the loading spring 53 by relieving a top abutment 52 and then to lift the diaphragm directly along with the spring through a stem 50 connected to the diaphragm. The member 55 has diametrically opposite pins 56 engaged in helical slots 66 in a fixed cover 41 of the valve body, these pins engaging also in longitudinal grooves 63 in a manually rotatable knob 60 whereby the lifting movement is imparted.

The opposite ends of the slots 66 have enlarged recesses wherein the pins 56 engage to lock the valve in closed or open position.

Title: Improvements relating to the separation of caprolactam from solution
Filed: 1952-01-11
Abstract: Caprolactam is separated from a solution in sulphuric acid or oleum by (a) neutralizing the solution with aqueous ammonia or ammonium salts having an alkaline reaction; (b) separating the caprolactam oil mechanically from the aqueous layer containing dissolved ammonium salts, and (c) mixing the oil with an alkali metal compound or with an alkaline earth metal compound having an alkaline reaction in sufficient quantity to convert the ammonium sulphate dissolved in the oil to an alkali metal or alkaline earth metal salt, separating the solid substances formed and distilling the oil at reduced pressure. Suitable alkali metal or alkaline earth metal compounds are sodium hydroxide, sodium carbonate, sodium borate, barium hydroxide, calcium hydroxide, potassium hydroxide, potassium carbonate, potassium silicate, sodium formate or potassium acetate.  In the example a solution of caprolactam in sulphuric acid prepared from cyclohexanonoxime by the Beckmann process is neutralised with aqueous ammonia; the resulting oil is mixed with sodium hydroxide, filtered and distilled under reduced pressure.
