Title: Process and apparatus for the treatment of artificial silk yarn
IPC: D06M13/188
Filed: 1928-06-29
Abstract: 311,137. Ploetner, O. June 29, 1928. Yarns.-Artificial silk yarn is coated with a mucilage of paste-like consistency, and the coating then smoothed and polished. Preferably the yarn is passed through the mucilage contained in a vessel or chamber, and then between pieces of rubber sponge. The mucilage consists of soft soap, gylcerine and potato meal, preferably in the proportion of 7 to 8 parts of soap, 1 to 2 parts of glycerine and 1 part of potato meal. Colloidal material such as white of egg, gum tragacanth, gum arabic or agar-agar may be used instead of potato meal. The yarn k, Fig. 1, runs from a reel a over a roller b and through an opening d in the lid of the vessel c. The latter is divided into two parts by a partition, the partition and one end of the vessel being slotted to permit passage of the yarn. The part g contains the mucilage, while the part h contains two pieces of rubber sponge of such width that their faces are pressed together when they are forced in. The yarn passes under a guide l, through the slot in the partition, between the faces of the pieces of rubber sponge and out through the slot in the end of the vessel. In the construction shown in Fig. 4, the vessel c is divided into three compartments, the outer two containing pieces of rubber sponge m<1>, m<2>, while the middle one contains the mucilage. Slots for the passage of the yarn are formed in the end walls and in the dividing partitions. The vessel may be supported in a pan q, to one end of which may be fixed a thread guide r.

Title: Improved process and apparatus for generating combustion products under pressure for heating and power purposes
IPC: F23C15/00
Filed: 1920-07-06
Abstract: 147,026. Riedel, F. Feb. 27, 1919, [Convention date]. Generating combustion - products under pressure for heating and power purposes. A mixture of gas and air is ignited in a combustion chamber a, b, and the products are allowed to escape with high velocity through exhaust pipes f, f so as to produce in the chamber b a reduction of pressure which permits air to enter in advance of the gas through lateral non-return valves g, for scavenging purposes and to support the combustion. The gas-inlet pipe to the ignition chamber a, and the combustion-chamber outlet are provided with valves c, e, respectively, which are coupled by rods h, i, k. After each explosion, the valve e is opened and the valve c closed, the impulse of the explosion being communicated through the rods h, i, k to a pendulum l the duration of oscillation of which is so adjusted that the return of the pendulum effects the opening of the valve c and closing of the valve e after air has been admitted to the combustion chamber through the valves g. Premature ignition of the gas is prevented by residual gases which remain in the chamber a. When starting up, or when using low-grade gas, ignition of the gas is ensured by the admission of air through a passage r and valve n which is opened during the latter part of the stroke of the gas valve c. Openings p in the valve c allow of some transference of pressure into the chamber b when the valve e is closed. In order to obtain a uniform discharge of combustion products, a number of combustion chambers with interconnected valve gear may be employed. Temperature, pressure, or velocity in the discharge are influenced by drawing in air &c. or by altering the cross sectional area. According to the Specification as open to inspection under Sect. 91 (3) (a), the valves c and c may be dispensed .with and liquid or solid fuel may be used instead of gas. Also. an alternative ignition device consists of a tube closed at one end and projecting into the combustion chamber and carrying a thin porcelain tube communicating at both ends with the combustion chamber and heated outside bv a burner. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to mixing valves for liquids
IPC: F16K11/065
Filed: 1957-06-17
Abstract: 901,761. Manually-actuated mixing valves. SHEARDOWN, J. M. Sept. 17, 1958 [June 17, 1957], No. 19028/57. Class 135. A manually-actuated valve for controlling the supply of cold water, a mixture of hot and cold water at a desired temperature, or hot water, comprises a valve plunger 8 formed with screwthreads 10 engageable with screw-threads 9 in a gland-nut 3 to move the plunger axially so that valving surfaces 16, 12 thereon are moved into and out of engagement with sealing-rings 14, 15 located in the bore 2 of a valve body 1, by collars 17, 18, to control flow between hot and cold inlets 4, 6, respectively, and a common outlet 7. In one extreme position of the valve plunger the valving surfaces 12, 16 engage the sealing-rings 14, 15, so that both the hot and cold water inlets are closed. On movement of the plunger outwardly, the surface 16 is first disengaged from the ring 15 to open communication between the cold water inlet 6 and the outlet 7. Further outward movement of the plunger then disengages the valving surface 12 from the ring 14 to allow the flow of hot water to take place and be mixed with the cold water, and, depending upon the position of the plunger the valving surface 12 co-operates with both rings 14, 15 to determine the temperature of the mixed water. In the other extreme position of the plunger, the valving surface 12 engages the ring 15 to close the cold water inlet with the hot water inlet fully open. The valving surfaces may be formed in the bore 2 or in a sleeve fitted therein whence the sealing-rings are carried by the plunger. A non-return valve may be fitted in the inlet for the liquid at the lower pressure, e.g. a ball valve 23 in the hotwater inlet 4. Instead of controlling the mixing of hot and cold water the valve may be used for mixing other liquids in desired variable proportions.

Abstract: 848,365. Electrostatic generators. HIGH VOLTAGE ENGINEERING CORPORATION. June 18, 1958 [July 2, 1957], No. 19467/58. Class 35. Metal sheets which provide the equipotential planes in the stationary column of a belt-type electrostatic generator, also serve to increase the lateral rigidity of the column. The stainless steel planes 17 are cemented in succession between glass insulators 16 so as to form a pair of insulating columns secured to the supports at one end and supporting the high-voltage terminal bulb at the other. The belt 13 runs on pulleys (not shown) one of which is mounted on the grounded support and the other is carried by the glass insulator columns inside the terminal. An aluminium belt spacer support 18 is press-fitted on each long edge of the planes 17 and serve to further increase the rigidity. The belt spacers are fitted with gradient bars 21 and alternate ones carry glass or porcelain belt-spacer rods 20 cemented in position. Each equipotential plane carries a conducting-ring 14 on end-bars 24, 25 which also support external belt spacers 28 and gradient bars 29 similar to those 18, 21, inside the belt. The end bars also support a resistive divider 30 serving to grade the potential along the whole column. An additional, thicker plane is incorporated at the earthed end of the column to provide a further increase in rigidity. The invention is described with reference to a horizontally-mounted column, but may be applied to vertical columns. The generator may work in gas under pressure. Spark-gap electrodes 19 on the planes 17 protect the glass insulators against surges. Specification 539,790 is referred to.

Title: Improved method for the production of esters of unsaturated acids
Inventor: SOUTHWOOD JOHN
IPC: C07C69/54
Filed: 1956-06-27
Abstract: Compounds of the general formula CH2 = CX.COOR, in which X and R are hydrogen or C1-4 alkyl groups, are reacted under acid esterifying conditions with a mixture of alcohols containing about 10-20 carbon atoms commercially known as lauryl alcohol, in the presence of catechol as a polymerization inhibitor, the reaction mixture being extracted with aqueous alkali and the lauryl ester recovered.  The inhibitor is suitably used in concentrations of about 1 per cent or more based on the weight of reactants, preferred concentrations being about 2 to 4 per cent.  The reactants may be heated in an inert solvent with an acid catalyst such as sulphuric acid or p-toluene sulphonic acid, suitable concentrations of catalyst being greater than 0.25 per cent by weight of the total charge.  When esters are used as starting material it is convenient to use an inert entraining liquid as solvent, so as to remove the lower alcohol formed; or with methyl methacrylate, excess may be used, and methyl alcohol removed azeotropically with the excess ester.  Molar quantities of reactants may be used, but preferably excess of the acrylic component is employed.  The reaction may be carried out at the boiling point of the mixture, e.g. under distillation conditions, suitably at 90 DEG to about 150 DEG  C., until no more water or alcohol of reaction is removed.  It is advantageous to add active carbon, e.g. about 2 to 5 per cent of the reactants.  After the reaction the mixture is washed with aqueous alkali, e.g. sodium hydroxide of about 5-10 per cent by weight.  After separation of the layers the organic layer is preferably filtered with a filter aid, such as diatomaceous earth. The lauryl ester may be recovered by distillation of excess acrylic acid or its derivative and solvent under reduced pressure, preferably not allowing the base temperature to rise above about 80 DEG  C.  In examples, the lauryl alcohol mixture is reacted with methyl methacrylate.
