Abstract: 1477112 Blasting WHEELABRATORFRYE Inc 7 Feb 1975 [10 Oct 1974 11 Nov 1974] 43973/76 Divided out of 1477111 Heading B3D A portable apparatus for blast-cleaning a surface, such as the hull of a ship or a storage tank comprises means 116, Fig. 2 for upwardly projecting particulate material onto a surface along a first defined passage with sufficient kinetic energy to rebound therefrom along a a second defined passage, a hopper 118 disposed above the means 116 for receiving the rebounded particulate material so that the material faces through the hopper by force of gravity back to the means 116, means for substantially separating debris from the particulate material prior to the entry of the material into the hopper, and means for removing residual kinetic energy from the particulate material and debris prior to entry into the separating means. As described, the apparatus has at least one, and preferably two, centrifugal blasting wheels 116 supplied with particulate material from a hopper 118 controlled by a slide valve 126 to throw the material vertically upward against a surface to be cleaned. As the spent particulate material rebounds from the surface it, and residues from the surface are deflected by a transverse air-flow from an inlet 134 into a rebound chamber 132, the air flow also acting to cool the blast area. The particulate material and residue is directed by a sloping surface 144 to a set of adjustable ledges 138, 140, 142. The material initially builds up on the ledges until it overflows and then falls as an evenly distributed curtain. A cross air flow from an inlet plenum 148 passes across the curtain and carries dust and fine particles to an exhaust plenum 150, exhaust fan 154 and dust collector 156, the heavier particles falling into the hopper for re-use. The conduit 124 from the hopper to the wheels 116 has quick-release connector rings 128 for providing access to the wheels in the event of jamming or for servicing. In order to prevent material, such as paint, removed from the surface being treated, building up on the impeller 170, Fig. 3, of the blasting wheel, a scraper block 174 may be secured to the conduit 124 and extend within the end 171 of the impeller. The apparatus has a seal 112 for engagement with the surface to be treated and, in order to ensure correct engagement, a positioning sensor is provided having contact shoes which engage the surface and are carried by arms movable about pivots to actuate slide potentiometers controlling hydraulic valves for operating a positioning unit for the apparatus. In another embodiment, a blasting head structure 212, Fig. 6 and 7, can be attached to either a side cleaning module 210 and the particulate material is thrown upwardly at an inclined angle for treating a vertical surface, or to an upblast module 214 and the particulate material is thrown vertically for treating the underneath of a horizontal surface.

Title: A new and improved malting plant
Inventor: POOL ALAN ALDRED
Filed: 1963-11-08
Abstract: A plant for malting grain has a stationary tank B and apparatus for conducting a succession of alternate steeping and germinating operations in the tank, which apparatus includes an air compressor C for introducing air under pressure, usually at between 5 and 10 lbs/sq. in., through nozzles g in the tank so as to agitate the mixture of grain and water during steeping, and an air conditioning apparatus D from which air of the requisite temperature and humidity is passed through the grain for germination, the direction of flow of the conditioned air through the grain being regulated by valves V3, V7, V6 and V8.  Th germinated grain is dried and cured by a flow of warm, dry air propelled by a fan (not shown) in a furnace E. The grain rests on either a perforated plate e, which is divided into two sections pivoted for downward movement about an axis e, or a conical lining spaced from the conical base of the tank B. Steeping water is kept at a desired temperature in a float controlled tank A until required in tank B.  The water inlet to tank B includes a spreading device f.  Scum and dirt collected on the surface of the water in tank B during the steeping are flushed out by opening valves V9 and V10.  The water supply is pre-heated in heat exchanger i by exhaust gases from the curing operation of air passed through the cured grain, and in heat exchanger j by waste hot steep water circulated by a pump F.  The conditioned air may be recirculated. A number of stationary tanks B may be serviced from a common water supply, air compressor, air conditioner and furnace, and the cycles of operation in the various tanks may be subject to automatic control.  The following sequence of operations is disclosed: (1) steeping grain for 6 hours at 18 DEG C. with intermittent periods of a few minutes each for aeration with compressed air, (2) germination for 22 hours at 18 DEG C., (3) steeping for 30 minutes at 18 DEG C. with aeration as in (1) above, (4) germination for 22 hours at 18 DEG C., (5) steeping for 75 minutes at 40 DEG C., aerating where necessary to loosen the grain, (6) germination for 44 hours at 18 DEG C., and (7) curing the grain using air first at about 40 DEG C. but rising steadily to 80 DEG C.  <PICT:1044029/C6-C7/1>

Valves 2 controlling the supply of heating and cooling water to room air conditioning units 1 in a three pipe system are controlled by a pneumatic control system having a main pressure line 16 connectable through room thermostats 15 and a signal transmitting main 17 to operate the valves 2, the thermostats being set via a set value main 18. The branch lines 19 and 23 for connecting the thermostats in the circuit have stop valves 22 and 24, stop valves 26 are provided in the signal main 17 between adjacent units 1, and stop valves 22 are provided in the branch lines 20 for connecting the thermostats to the set value main 18. As illustrated, partitions 9-13 divide the area shown into four rooms A-D, and only the thermostats 15a are connected. The valves 21a, 22a, 24a and 26a are open and the valves 21z, 22z, 24z, and 26z are closed so that one thermostat in each room controls all the conditioning units in that room. The thermostats are reverse acting, i.e. lower room temperature causes increased pressure in the branch lines 25 which increased pressure moves diaphragms associated with the valves 2 to increase the heat supply to the units 1. The pressure in the set value main determining the setting of the thermostats 15a is controlled by an outside temperature detector 28 through a controller 27. At night a thermostat 32 is connected into the main 16 either manually or automatically, the temperature to which the thermostat 32 is adjusted being below the operating range of the thermostats 15 so that all the units 1 are controlled by the pressure in the main 16 as determined by the thermostat 32.
