Title: Hot repair of refractory linings
IPC: F27D1/00
Filed: 1979-06-01
Abstract: The invention concerns the hot repairing of refractory linings of furnaces and the like. Difficulty has been experienced with repair compositions employed heretofore in obtaining both the required immediate adhesion of the composition to the damaged lining and adequate refractoriness of the completed repair. The invention is directed to avoiding this disadvantage by a method which involves applying two layers of refractory material to the damaged lining, in which an easily adhering refractory composition with a high proportion of fine particles and a high binding agent content is applied to the lining to be repaired as the first layer and then a sinterable, wear-resistant, refractory composition is applied as the second layer. The first layer adheres better than prior repair compositions and effects some cooling of the repair site, and the second layer adheres to the first better than it would to the untreated repair site. Conventional hot repair refractory materials can be employed as the basic refractory material for both layers. The first layer is preferably a refractory rich influxing agent, e.g. sinter magnesia rich in iron, and the second layer preferably employs a refractory of greater heat and wear resistance, e.g. magnesia low in iron.

Title: Improvements in Waste Gas Recovery Systems
IPC: C10L3/00
Filed: 1979-11-06
Abstract: A waste gas recovery system employs a compressor (20) which takes in raw waste gas from an inlet knock-out drum (10) and passes compressed gas through a heat exchanger (24) to an outlet knock-out drum (11). The temperature at the outlet of the compressor (20) is sensed by a device (18) which operates valves (28, 29), to inject liquid coolant into the compressor inlet and to re-circulate gas back from the outlet of the outlet knock-out drum (11) to inhibit an excessive temperature rise. A pressure-sensing device (19) senses the pressure of the gas passing into the compressor (20) and controls both the speed of the compressor (20) and an adjustable throttle valve (27) to regulate the gas flow. The throttle valve (27) is closed automatically should there be a fall in the pressure of the gas at the inlet below a safe level. In this event, further pressure-sensing devices (92, 97) act additionally to close the recirculating gas valve (29) and a further valve (84) in the main inlet flow path to reliably isolate the compressor (20). <IMAGE>

Title: A projectile having a thermo- electrical generator
IPC: F42C15/40
Filed: 1981-01-22
Abstract: There is described a projectile having a thermo-electrical generator for the operation of a circuit arrangement in the projectile, the operating voltage of said generator being acquired by virtue of a temperature gradient or gradients at or in the projectile which occur in operationally-caused manner as a result of the projectile acceleration in a weapon tube and/or of the projectile deceleration in free flight. In this respect there can result an intrinsically-safe projectile when the generator is formed or provided over a projectile region over which there occurs substantially by virtue of free-flight factors after emergence from the weapon tube temperature gradients of such order of magnitude and direction as to supply by way of the generator, according to amplitude and polarity, possibly by way of a voltage multiplier, the necessary voltage for the feeding of the circuit arrangement. Such regions are more especially (i) a projectile tip, (ii) a transitional region from the tip to cylindrical projectile walling, (iii) (in the case of a projectile having a spike tip) a region directly in front of a shoulder of the projectile, and (iv) a projectile region behind a guide ring of the projectile. In the latter case, the heat impingement of the generator by the propellant gases in the weapon tube can also be utilised to feed the circuit arrangement prior to passage of the projectile through a dead region immediately in front of the weapon tube muzzle and for acquiring tube-emergence sensing information. In the embodiment shown, a projectile 1 has a thermo- electrical generator 9 which is arranged in the tip 10 and by which is operable a circuit arrangement 8. 12 is a heat sink. <IMAGE>
