IPC: F23J15/04
Filed: 1967-09-26
Abstract: 1,229,915. Incinerator. DOWSON & MASON Ltd. 21 Oct., 1968 [26 Sept., 1967], No. 43752/67. Heading F4B. In a refuse disposal system for a multistorey building, the closure of a valve 12 in the collection shoot 2, the ignition and burning of refuse on a grate 7 in a single operation and the discharge of ash from the grate 7 into a container 8 below the grate are automatically controlled as a single timed cycle. The shoot 2 receives refuse from individual hoppers 3, and a flue 13 leads from the combustion chamber 5 to a water wash 14 and a fan 15 exhausts gases to a flue 4. The burner 6 in the combustion chamber fires across the outlet to the flue so that the gases are completely burnt. A single time clock closes the gate valve 12, switches on the water wash unit 14, induced draught fan 15 and burner 6 to burn the refuse collected during the day. After a predetermined period, the burner 6 is switched off, the wash unit 14 and fan 15 remaining in action and the valve 12 remaining closed for a further period to cool the incinerator. After a suitable interval, the grate 7 is dumped into a dustbin 8 on a trolley, fly ash being removed by the water wash unit. An inter lock prevents the grate being dumped unless the dustbin 8 is in place. After the grate 7 has returned to its normal position, the valve 12 is closed, and the water wash unit 14 and fan 15 are switched off, the incinerator remaining at rest while a further day's refuse is collected on top of any refuse retained by the closed valve 12 and fed to grate when the valve is opened. The grate 7 may be dumped at the end of the burning period but before the cooling cycle, or water may be directed into the combustion chamber after burning is complete. The water for the wash unit may be recirculated from a storage tank.

Abstract: 1,233,390. Microporous sheet material. FARBENFABRIKEN BAYER A.G. 9 Dec., 1968 [7 Dec., 1967], No. 58391/68. Headings C3C and C3R. Microporous polyurethane-urea sheet material is produced by reacting (1) one or more compounds containing at least two terminal NCO groups and having a M.W. of 100 to 10,000, and (2) water, as a chain-lengthening agent, in a reaction medium which comprises at least one non-solvent for the polyurethane-urea, so that the polyurethane-urea produced has (1) a Shore A hardness of at least 50, (2) a tensile strength of at least 50 kg./cm.<SP>2</SP> and (3) a softening range above 80‹ C., an at least equivalent amount of chain-lengthening agent being used, based on the amount of (1), applying the reaction medium, while it is still pourable, to a substrate and shaping the mixture and removing the reaction medium, or allowing the reaction medium to evaporate from the shaped product. The microporous material so produced may then be stripped from the substrate. If desired, an additional chain-lengthening agent which contains at least two OH or NH groups and has a M.W. of 50 to 600 may be added to the reaction mixture. The non- solvent may be, e.g. an aromatic hydrocarbon, aliphatic hydrocarbon, petroleum fractions, cycloaliphatic hydrocarbons, chlorinated hydrocarbons, esters, ketones, ethers, nitro compounds, alcohols and nitriles. They may be used in admixture with a solvent for the polyurethane-urea. Water used as the chainlengthening agent may at the same time be used as the non-solvent. Catalysts such as tertiary amines and tin compounds may be added to the reaction mixture. The NCO group-containing compound is preferably a polyurethane prepolymer, optionally mixed with a monomeric polyisocyanate. In a typical example, water is dispersed in a 25% solution in benzene of an NCO propolymer prepared by reacting a mixture of 2,4- and 2,6-toluylene diisocyanate with a polyester derived from adipic acid and diethylene glycol. After the addition of triethylamine, the dispersion is stirred, poured on to metal plates and after the polyaddition is finished, the solvent is evaporated.

Abstract: 1,238,354. Titanium dioxide. TITAN G.m.b.H. 16 Oct., 1968 [20 Oct., 1967], No. 49166/68. Heading C1N. In a process for cooling the products of the reaction of titanium tetrachloride with oxygen, the titanium dioxide suspension which issues from the combustion chamber is passed downwardly into a vertical cylindrical cooling chamber at the bottom of which runs a cooled rotor, which simultaneously cools and circulates the suspension. Part of the cooled suspension discharged by the rotor is withdrawn from the system at the rate at which hot suspension enters the cooling chamber from the combustion chamber, and the remainder of the cooled suspension is returned to the combustion chamber outlet where it pre-cools hot suspension entering the cooling chamber. The cooled suspension may be recirculated to the combustion chamber outlet without it leaving the cooling chamber, or it may be recycled outside the chamber. In that case, the coarser TiO 2  particles may be removed from the suspension before its return to the combustion chamber outlet. The amount of suspension circulated by the rotor is preferably many times greater than the amount entering the cooling chamber from the combustion chamber in unit time. The suspension withdrawn from the system may be cooled to 700- 500 C. and may be subsequently cooled further e.g. to 400 C. by mixing with inert gas. Cooled inserts e.g. cylinders with radial projections, may be provided in. the cooling chamber to control flow conditions. In one embodiment (Fig. 4) a water-jacketed cooling chamber 1 is located below combustion chamber 2 and contains a water-cooled rotor 6 and a water-cooled insert 7 which, together with a cut-off plate 8 prevents direct return of cooled suspension to the outlet of 2. Cooled suspension leaves 1 tangentially at 4 and re-enters, after removal of coarse particles at 9, tangentially at 11. The proportion of suspension withdrawn from the system is removed at 10. In a further embodiment, not shown, where cooled suspension is re-cycled inside the cooling chamber, the cooled suspension outlet is located in the upper part of the chamber. Reference has been directed by the Comptroller to Specification 817;940.

Abstract: 1,250,412. Electric switches. ESSEX INTERNATIONAL Inc. 30 Jan., 1969 [2 Feb., 1968], No. 5214/69. Heading H1N. [Also in Division G4]  In vehicle signalling apparatus having an operator 7 for operating direction signals and an actuator 25 movable from an inoperative position (Fig. 1) to an operative position (Fig. 5) for operating both direction signal indicators simultaneously such as for hazard signals, cancelling means 48-50 is provided operable in response to operation of the operator 7 to return the actuator 25 to its inoperative position. By pushing in hazard warning switch 25 an abutment 48 and end 32 of the actuator 26 of this switch are moved from the position shown in Fig. 1 to that shown in Fig. 5. This also causes movement of a pin 45, which is secured to a switch carrier 35a, in a slot 43 formed in the actuator 26. Movement of the pin in the slot causes the carrier 35a to move to the right and connect movable and fixed contacts 39, 34 of the hazard switch. This connects an auxiliary flasher (F-2, Fig. 7, not shown), to flash all the direction signal lamps. The flasher (F-1) used for the turn signals is connected to the direction signal lamps by a direction signal switch 13 (G) which is operated via a pin-and-slot arrangement 15, 16 by the turn lever 10 and operator 7.  The hazard switch actuator 26 is latched in the operative position by the pin 44 being located in a slot 46 due to the action of a spring 38. On moving the direction indicator switch lever 10 and operator 7 angularly to either of the turn positions or from one turn position to the neutral position, the pins 49, 50 attached to the operator 7 cause abutment 48 to return the hazard actuator 26 outwardly to the inoperative position shown in Fig. 1, where the contacts 39 and 34 disengage. Also the hazard actuator 2 may be returned to the inoperative position by rotation of the vehicle steering wheel shaft 4 which causes a cam 5 to abut the end 32 and return the actuator 26. Further, the hazard switch 25 may be also returned by pulling the knob 28. The direction indicator switch operator 7 is returned to the neutral position by the cam 5 abutting fingers 17 on rotation of the steering shaft 4. The Specification draws attention to Specification 991,720.

Abstract: 1,252,734. Photographic type-composing apparatus. TRIGGS & GATTER Ltd. 15 Nov., 1968 [16 Nov., 1967; 15 Dec., 1967; 19 Feb., 1968], Nos. 52193/67, 57209/67 and 8077/68. Heading B6W. A photographic type-composing apparatus comprises means for scanning an image of a control marking associated with a selected character and means controlled by the scanning means for moving the sensitive recording surface an appropriate distance to provide a predetermined character spacing. In a preferred form the characters and associated control markings 23 are provided on a rotatable matrix disc 13. Required characters are coded on input tape 54 and the disc is stopped by brake 49 and detent 50 when a required character is aligned with the exposure station. The position of the disc is monitored by photo sensitive elements 51 which detect code marks 48 on the disc. The disc may have associated therewith shutters 24, 25, Fig. 3A, which serve to protect the recording surface from the exposing light as the required character is brought into position and to expose the control marking 23 for scanning while still preventing light from the character image 22 reaching the recording surface. The projected image of the control marking 23, Fig. 4, is scanned by photo-cell 4 mounted on movable carriage 21. As long as the cell 4 is activated by detection of area 23 the film 27 is transported. When cell 4 passes beyond area 23 the film is arrested and the imaging exposure made by movement of the above mentioned shutters. To change the character spacing a movable shield may be used to obscure part of area 23 thus cutting down the amount of cell activation and thus cutting down the amount of film transported. In a further embodiment the cell is deactivated as normal when it passes beyond the left hand edge, Fig. 4, of area 23 thus stopping film transport, but the transport is initiated by variable means not associated with the position of the right hand edge of area 23.
