Abstract: Esters of organic acids of general formula Cl-(CH2CH2CH2CH2O)n-CORX, where n is 1 or 2, R is a bivalent hydrocarbon residue and X is hydrogen or Cl-(CH2CH2CH2CH2O)n\t -CO-, are used as plasticizers in cellulose derivative compositions.  Such esters are the delta-chlorobutyl and delta-chlorobutoxybutyl esters prepared by reacting tetramethylene oxide and the corresponding acid chloride (see Group IV (b)).  Cellulose derivatives with which they may be employed include the nitrate, acetate, propionate, butyrate, acetate-propionate and acetate-butyrate and also the ethyl and benzyl ethers, and to each 100 parts by weight of cellulose derivative there may be added 5 to 75 parts by weight or more of the plasticizer.  The plasticizers are compatible also with vinyl polymers such as polyvinyl acetate, polyvinyl chloride and polymethyl methacrylate, p and coumarone-indene synthetic resins.  In an example, 100 parts by weight of ethyl cellulose of 45-47 per cent ethoxyl content are mixed with 20 parts by weight of di-delta-chlorobutyl phthalate and 1 part by weight of calcium lactate as a stabilizer, the resulting composition being used for moulding at 200 DEG  C.ALSO:Esters of organic acids of general formula Cl-(CH2CH2CH2CH2O)n-CO.RX where n is 1 or 2, R is a bivalent hydrocarbon residue and X is hydrogen or Cl-(CH2CH2CH2CH2O)n\t -CO- are used as plasticizers in cellulose derivative and synthetic resin compositions (see Group IV (a)). These esters are prepared by refluxing tetramethylene oxide with the acid chloride of the carboxylic acid whose ester is desired, preferably in the presence of an amount of from 0.5 to 5.0 per cent by weight of the tetramethylene oxide of a catalyst such as anhydrous zinc chloride, aluminium chloride, concentrated sulphuric acid or concentrated phosphoric acid.  In an example tetramethylene oxide and acetyl chloride are reacted in the presence of freshly-fused zinc chloride.  Refluxing commences at 73 DEG  C., and the temperature rises to 84 DEG  C. at which temperature the mixture is refluxed for two hours.  When the amount of water-insoluble products reaches a maximum, the product is fractionally distilled, yielding chlorobutyl acetate and chlorobutoxybutyl acetate.  The preparations of chlorobutyl stearate and di-delta-chlorobutyl phthalate are also described, and the preparation of esters of heptoic, caproic, capric, lauric, succinic, adipic and sebacic acids is mentioned.

Filed: 1962-04-18
Abstract: <PICT:0937129/III/1> <PICT:0937129/III/2> <PICT:0937129/III/3> <PICT:0937129/III/4> A machine for adheivesly bonding two workpieces while they are moved by feed rolls 12 and 14 past a nozzle 24 through which adhesive is extruded on to at least one of the workpieces comprises a pot 30, a chamber 46 in the pot 30 in communication with the nozzle 24, means for supplying adhesive to the chamber 46, e.g. well 32, a cylinder 50 communicating with the chamber 46, a plunger 52 slidably mounted in the cylinder 50 and motor 56 for reciprocating the plunger 52 in the cylinder, which motor 56 is controlled by means sensitive to the movement of the workpieces. The machine includes a ball valve 40 to control passage of adhesive into the chamber and heaters 62, 63 to keep the adhesive molten.  In operation, molten adhesive flows from well 32 to chamber 46 via passages 36, 38.  When a workpiece moves into a position so treated the motor 56 is actuated such that plunger 52 moves towards the chamber 46 forcing ball valve 40 to stop the entry of adhesive into the chamber 46 and also forcing molten adhesive out of nozzle 24 via passage 60.  When the workpiece moves out of the treatment zone the motor is actuated such that the plunger 52 moves away from the chamber 46 and ball valve 40 falls back to its original position.  The operation of the motor 56 is controlled by solenoid valves 72 and 74 which are controlled by switch 68.  When no workpiece is passing the nozzle 24 compressed air flows from conduit 26 to conduit 28 distending diaphragm 66, the switch 68 is open, the solenoid valves 72 and 74 are de-energized and the motor is supplied with air via valve 80. When the workpiece moves past the nozzle 24 the compressed air is prevented from passing to conduit 28 and hence the switch 68 is closed, the solenoid valves 72 and 74 are energized and the motor is supplied with air via valve 84. Specification 862,213 is referred to.

Title: Apparatus for producing hollow articles or containers from paper pulp
IPC: D21J7/00
Filed: 1935-05-24
Abstract: 440,543. Moulding hollow articles from pulp. MARGUERAT, R., and CHEVRIER, M., 7, Rue Carves, Montrouge, Seine, France. May 24, 1935, No. 16162. [Class 87 (ii)] Apparatus for moulding hollow pulp articles comprises a rotary member 14 carrying female foraminous moulds 12 and rotating about a shaft 25 having passages 24 therein through which suction is applied to a measured quantity of pulp delivered to each mould in succession by means operated in timed relation to the carrier member 14, the suction extracting water from the pulp and producing a matted deposit on the moulds, which deposit is pressed by means operated in timed relation to the carrier 14, and is afterwards removed and dried. The carrier moves each mould to positions where the pulp is pressed by a male mould 30, the article is removed, and the moulds are cleaned. Pulp in a trough 1 is caused to flow over the edges of a funnel 4 to a predetermined amount by submersing a body 2 in the pulp. The body 2 reciprocated by a rod 10 and is connected by mechanism 7, 8, 9 to a valve 6 which allows the pulp to flow through a funnel 11 to a mould 12. The funnel 11 is raised to allow each mould to pass to a position B where the male mould 30 is introduced on a reciprocated piston 27. The pulp article is pressed and freed from the mould 12 by air pressure through a passage 24<1> and by suction through an axial bore 34 in the piston connected to a pipe 35. The article is blown back to adhere lightly to the mould 12 by compressed air introduced through the bore 34 from a pipe 35<1>.

Abstract: 457,392. Steam-traps. MAYER, E., and MAYER, H., (trading as HUBNER & MAYER), and AUGUSTIN, E., 64, Muthgasse, Vienna. May 24, 1935, No. 15226. [Class 64 (ii)] In a steam &c. trap controlled by a floatoperated slide valve, the valve-plate is slewed at the beginning of its opening or closing movement. The trap may comprise a chamber 1 communicating through a port 4, an orifice 7, and a tube 5 with a jacket space 3 having a fluid inlet 2, and through a port 17 controlled by a slide valve with a discharge passage having a helical baffle 21 and forming a liquid seal for preventing the escape of vapour. The valveplate is carried by a cap 15, Fig. 3, having extensions 14, the axes of which are in the plane of the port 17, engaged by the legs of a forkedmember 12 operated through counterweighted float mechanism. In operation, fluid enters the space 3 and passes through the port 4 into the chamber 1, the pressures in the space and the chamber being equalized through the tube 5. As the liquid level in the space 3 and the chamber rises, the pressure equalization is destroyed by the sealing of the lower end of the tube and the float rises and slews and opens the valve as shown in Fig. 5. The discharge through the port 17 creates a partial vacuum in the chamber and induces a rush of fluid from the space 3 and equalization of the pressure.

[Class 97 (ii)] [Also in Group XIX] A directional flight level indicating instrument comprises a dial marked in altitude graduations and a north-seeking needle which indicates the altitude at which the aircraft must fly when travelling in any direction to avoid collision with other aircraft flying in any other direction and using a similar instrument. In practice, the aircraft when flying due north flies at, say, " even " thousands of feet, when flying due south flies at " odd " thousands of feet, and when flying in any other direction flies at a level which includes an additional number of feet to the " even " or " odd " thousands, the aircraft when ascending or descending flying on a spiral course. As shown in Fig. 1, a fixed dial 6 is graduated as shown, and is divided into " even " and " odd " parts 9, 10. A north-seeking needle 7 is provided. When the aircraft changes its flying bearing, the dial moves relatively to the needle 7 which thereupon indicates on the appropriate half of the dial the number of additional feet the aircraft must be flown above the " even " or " odd " thousands of feet, an altimeter being necessary. Fig. 2 shows an instrument which also incorporates an altimeter which has been adjusted to a fixed barometric pressure. To fly the aircraft at the correct height for the course bearing, it is only necessary for the pilot to maintain the barometrically-operative needle 13 in a superposed position with the north-seeking needle 12. Various other forms of instrument are described.
