Patent FI-982164-A (FI)
Inventor: LEVANTO ANTTI-PEKKA
IPC: F23L/
Filed: 1998-10-06
Abstract: The invention relates to a method for regulating the flow of combustion air 9-11 to a fireplace as well as a regulating arrangement for the combustion air. The combustion air is carried through a standardised shut-off device 19 to an air distribution channel 8 from which the combustion air via nozzle openings 17-18 adjustable specifically for each fireplace is carried in a controlled way further on to the fireplace. Between the surrounding air and a combustion compartment, a separate adjustable air distribution channel 8 is arranged, the openings 10, 19 of which for incoming air essentially open towards the surrounding air, and openings 12 for the expelled air via a regulating arrangement 14, 17, 18 essentially open towards the combustion compartment in a corresponding way. <IMAGE>

Title: Improvements relating to the detection or determination of the quantity of suspended solid matter in gas streams
IPC: G01N15/06
Filed: 1942-01-26
Abstract: 554,985. Fire alarms. BRITISH ELECTRI-' CON (LONDON) Ltd., and CHAMBERS, W. A. Jan. 26, 1942, No. 1093. [Class 118 (i)] [Also in Groups XX and XL] An apparatus for detecting or measuring suspended matter in a stream of gas (for example, for detecting smoke in a stream of air drawn from the hold of a ship) is provided with means for setting up one or more electrostatic fields by which suspended particles are caused to move transversely to the stream, and with means for detecting or measuring the concentration of particles thus moved. As shown, the air stream is drawn through 'a chamber having an inlet 1 and outlet 2 of insulated material connected by a metallic wall 7. An insulated. wire electrode 3 extends down the centre of the chamber and is surrounded by a cylindrical grid electrode 8 of gauze. A large potential difference is maintained between the electrodes 3 and 7 and the grid is maintained at an intermediate potential. The air passing through the chamber is thus divided into a main inner stream and a subsidiary outer stream the subsidiary stream issuing through outlets 13. The electrostatic action moves the smoke particles into the outer stream where they may be detected by a photo-electric cell 15 illuminated by a lamp 16 and mirrors 17, 18. In a modification, the subsidiary stream may pass through a visual detection cabinet.

In order that a coin dispensing mechanism may be housed beneath the level of a counter the coins dispensed by the mechanism are fed to a conveyer which raises the coins to a receptacle at counter level. The conveyer comprises a pair of endless bands 71, 85, Fig. 4, between which the coins are sandwiched for transport from a slot 67, where they enter the conveyer, to a shoot 101 by means of which they are discharged to a coin tray 64. The endless bands are spread apart by roller 86 together the coins entering by way of slot 67 and they diverge from roller 82 to take separate return paths to driving roller 72 and to discharge coins into shoot 101. As shown in Fig. 2 the bands are housed between a sidewall 59 and a dividing plate 70 on the other side of which the driving motor 109 is mounted.

Title: Weighting filaments of synthetic linear polyamides
IPC: D06M11/71
Filed: 1941-02-07
Abstract: 547,039. Treating textiles with liquids ; dyeing processes. BRITISH CELANESE, Ltd. Feb. 7, 1941, No. 1643. Convention date, Feb. 7, 1940. [Class 15 (ii)] Textile material comprising filaments of synthetic linear polyamides are impregnated with a solution of a weighting metal compound and the weighting metal is then fixed on the material as an insoluble compound. The synthetic linear polyamide may be one made by condensing a diamine with a dicarboxylic acid or one obtained by self-condensation of an amino acid. It may be obtained from tetra-, penta-, or hexa-methylene - diamine and adipic, suberic, or sebacic acid, or from octa-, or decamethylene - diamine and adipic or p-phenylene di-acetic acid, or from 4 : 4<SP>1</SP>-di(aminomethyl)- benzene and sebacic acid. It may be obtained from 6 - amino - caproic acid or 9 - amino - nonanoic acid. The filaments obtained from these polymers may be subjected to stretching treatment. Weighting may be effected by treatment with solutions of salts of tin, lead, titanium, zinc, antimony, aluminium, bismuth, or tungsten. Impregnation may be effected at raised temperature and in the presence of swelling agents, e.g. formic acid. The fixing treatment may be carried out by subjecting the impregnated material to a hydrolytic treatment for the weighting metal compound and then treating with a solution of a substance capable of forming an insoluble compound of the weighting metal. Stannic chloride may be hydrolysed by washing. Disodium hydrogen phosphate may be used as fixing agent. It is preferred to treat also with a second fixing agent such as sodium or potassium silicate. Yarns, staple fibre, or fabrics may be treated. The treatment may be performed on the tensioned or untensioned materials which may be travelling continuously through the baths. The textile material may contain, besides the polyamide filaments, filaments of cellulose acetate or other cellulose ester or ether, regenerated cellulose, silk, cotton, or wool. The weighting treatment may also subdue the lustre, and increase the affinity for silk, wool, and direct cotton dyes. It gives the material a fuller and silkier handle, raises the melting point, and increases the elongation in both dry and wet state.

Class 40 (4) [Also in Groups XXXVIII and XL (b)] In a piezo-electric pick-up in which a single crystal 18' carries two styli 23 adapted for alternate use, the crystal is mounted for torsional movement between spring-metal members 25 which position the crystal within the pick-up casing. As shown in Figs. 5 and 11, the casing is formed by two similar synthetic resin mouldings 5, 6 having complementary recesses 7, 8. Locating notches 11 are provided for the spring metal members 25 which are so shaped and positioned that their central portions 27, Fig. 7, engage the longitudinal axis of the crystal, interposed cushioning strips 30 which may be formed of cellulosic insulating material or polyvinyl-chloride being optionally provided. The crystal is additionally supported within the casing by rubbersheathed trunnion pins 24, Fig. 10, which engage recesses 12. These pins extend outwards from channel-shaped, copper-alloy stylus carriers 20 which are fitted to opposite edges of .the crystal and have hollow tubular extensions 21 of flattened cross section which support removable stylus-carrying rods 22. Leads 19 from the crystal are fitted with tags which are positioned within correspondingly-shaped recesses 13. The pick-up is assembled by securing the two mouldings 5, 6 edge-to-edge with bolts 29, Fig. 12, and is rotatably mounted on a metal carrier 32 which is secured within the pick-up arm 3. At the outer end of the  pick-up a spindle 41 carrying a knob 42 and passing through a hole in the carrier fits within a casing extension 14 formed by the assembled casing mouldings. At the other end the pick-up is supported for rotation by a pin 35 which engages an extension 15 of the casing. A spring 36 is fitted over the pin and urges the pick-up to a forward position so that moulded lugs 43, 44 engage stops 40 formed in the metal carrier when the pick-up is in either of its 180 degrees-displaced operative positions. According to the Provisional Specification the spring-metal members may be formed from copper stampings and may comprise arcuate spring bars joined by webs or slotted and bent plates.

Title: Improvements in the manufacture and production of non-knocking motor fuel
IPC: C10G35/10
Filed: 1933-01-19
Abstract: Middle oils, benzines and benzols boiling below 375 DEG  C. are destructively hydrogenated, cracked and purified from sulphur by subjecting them to a heat treatment in the "non-vaporous phase" in the presence of finely divided catalysts while continuously passing the oils and catalyst dispersed therein together and at the same speed through the reaction chamber e.g. a pipe coil.  The term "non-vaporous" phase includes the liquid phase and the gaseous phase at temperatures above the critical temperature but under such pressure that the density of the materials under treatment is not substantially less than that of the normally liquid materials when just below their critical temperature.  The refined products may be subjected further to destructive hydrogenation or cracking.  Crude benzol with 10 per cent of a colloidal catalyst dispersed in oil and comprising active carbon impregnated with molybdic acid is passed with hydrogen at 200 atmospheres pressure and at 410 DEG  C. through a reaction vessel.  To assist in maintaining the materials in the liquid phase small amounts of heavy, preferably cyclic, hydrocarbons may be added. Specification 377,938 is referred to.
