Patent GB-342674-A (GB)
Title: Improvements relating to adhesives
IPC: C09J161/06
Filed: 1929-10-28
Abstract: The component parts of composite articles are united by an adhesive comprising a cellulose derivative and a resin obtained by condensation of a phenol with an aliphatic ketone.  The term "phenol" includes phenols, cresols, and more complex phenolic bodies such as diphenylol propane, but excludes resinous substances obtained from phenolic bodies.  The resins are preferably prepared in the presence of an acid catalyst and should be fusible and soluble.  Resins prepared by condensing diphenylol propane and a ketone, according to Specification 299,066, [Class 2 (iii), Dyes &c.], are especially valuable.  The adhesive may also contain other synthetic resins, natural resins such as shellac, dammar, kauri, acaroids, and rosin, or semi-synthetic resins such as condensation products of phenol-formaldehyde resins and rosin, and ester gums, which resins should be compatible with the cellulose derivative present, that is, both should be soluble in a common solvent, or mixture of solvents, and give clear, homogeneous films on evaporation.  Suitable cellulose derivatives are esters such as cellulose nitrate, acetate, formate, propionate and butyrate, or ethers such as ethyl, methyl, and benzyl cellulose.  The amount of film-forming material in the adhesive solution may vary considerably.  A low boiling solvent such as acetone, chloroform, ethyl or methyl alcohol, ethyl acetate, methylene chloride, ethylene dichloride, benzene, or a mixture of any of these is used, if desired together with medium and high boiling solvents, such as ethyl lactate, diacetone alcohol, and benyzl alcohol, or plasticizers and softening agents such as camphor, triacetin, diethyl phthalate, dibutyl tartrate, or diphenylol propane.  The component parts may be of any shape and material e.g. glass, metal, paper, cardboard, wood, asbestos, composition board, stone, brick, ceramic material, leather or fabric, or they may contain a cellulose derivative, and may be of the same or of different materials.  The adhesive may be used for uniting smooth surfaces; thus glass is secured to bricks or walls, or sheets containing any of the cellulose derivatives mentioned are secured to plaster, asbestos or composition board or other material used in wall or ceiling construction, or to metals.  The cellulose derivative sheets may contain dyes and pigments, and materials to give variegated, mottled or like decorative effect, in addition to any of the resins above mentioned.  The adhesive solution is applied by brushing, spraying or flowing on to one or both surfaces to be united.  The coating may be left to become tacky and the surfaces pressed together at ordinary or elevated temperature and allowed to ripen.  The adhesive preferably contains the same cellulose derivative and resins as the sheet material.  An adhesive solution given as an example contains 1 to 9 parts by weight of cellulose acetate, 9 to 1 parts of diphenylol-propane-acetone resin, 2 to 10 parts of diethyl phthalate, 50 parts of acetone, 25 each of benzene and alcohol, and 10 of ethyl lactate.

Filed: 1974-07-24
Abstract: 1474421 Hydraulic control circuits DEERE & CO 24 July 1974 [25 July 1973] 32760/74 Heading F1P In the circuit shown in Fig. 1, the output of a pump 10 is controlled by a pressure responsive valve 38, which decreases pump output as the pressure rises by feeding pressure fluid to a control chamber of the pump, and is acted on in the sense tending to open the valve by pump pressure and in the sense tending to close it by pressure in a pilot line 56 which is normally coupled by a valve 58 to a line 24, the valve 58 being arranged to close when pressure in the line 24 reaches a predetermined level. A spring 48 determines the stand-by pressure of the pump and when the valve 14 is opened pressure fluid passes through the line 56 and valve 58 to push a piston 52 to the left, thus closing the valve 38. The pump pressure therefore rises. If the valve 14 is closed before excess pressure closes the valve 58 pressure in line 56 is exhausted through a restriction 90. If the valve 14 remains open and the pressure continues to increase, a piston 82 is moved to the right to close a pressure responsive switch 68. This closes the solenoid valve 58 which allows the valve 38 to open and decrease the pump output. Fig. 2 (not shown), illustrates a modified circuit in which a pressure responsive valve 138 controls the pump output by means of a piston and cylinder arrangement 194, 192. The restrictor 90 is omitted and the connection between the ram 112 and the solenoid valve 158 is different.

Abstract: 1,198,711. Control systems for X-ray apparatus. MEDICOR MUVEK. 19 July, 1967 [19 July, 1966], No. 33121/67. Heading H2H. A control system for an X-ray apparatus comprises means for developing voltages which are representative of the voltage applied to the anode of the X-ray tube, the current flowing through the tube and the period of the exposure, the three voltages so produced being used to control the heating of the tube cathode. In one embodiment each control means adjusts the tapping on a transformer and the setting of a variable resistor, the three voltages and the three resistors being connected in a series circuit including the primary winding of a transformer, the secondary winding of which supplies the heating element for the cathode of the tube. In a second embodiment each tapped voltage from a transformer is used to control a pair of control windings of a saturable reactor whilst the three variable resistors are serially connected with a fourth pair of control windings on the transductor, the load windings of the transductor being connected in series with the primary winding of the cathode heating transformer. Thus the apparatus permits the tube to be operated using differing focus conditions and also allows the changeover from one tube to another.
