Abstract: 1448265 Concrete mixing installations CASTONE DEVELOPMENT CORP 2 Nov 1973 [16 Nov 1972] 51105/73 Heading B1C [Also in Division B5] Mixing:- Cement is delivered by a continuous weigher and a screw conveyor 24, and aggregate by a continuous weigher and a belt conveyor 23, to a blender crusher 22 and thence to a belt conveyor 25 where liquid is continuously added at 42, the dry and wet mixers being agitated by stationary combs 35-40 and rotary mixing heads 32-34 having downwardly projecting fingers. The amounts of solid materials supplied and the belt speeds may be automatically controlled by demand and the liquid by a a moisture sensor at the delivery end of the belt 25. Moulding. The mix is continuously discharged into a hopper 48 reciprocable between two positions as shown in both of which it can receive the mix. Its bottom has transverse plates 67 slotted to receive and slide along upstanding stationary longitudinal plates (65, Figs. 2 and 3 not shown) fixed to plate 66 and continuous with plates 53: the plates (65), 67 form a false mould defining brick-size cavities corresponding to those formed by mould plates 53, 54. In operation the plunger head 71 is first raised so that the brick-size projections thereon enter the mould cavities, their tops being level with plate 66. The hopper 48 is then moved over the mould and the plunger lowered to the position shown drawing the preformed bricks from the hopper into the mould where they are compacted by vibrators (57, 58). A constant static head of material is maintained in the hopper to pre-cure the bricks. The hopper is returned to its first position, shearing off the bricks which are pushed up out of the mould by the plunger 71. The bricks are pushed on to a carriage 80 and thence to a pallet 74 by the return of the hopper on succeeding cycles. They are pushed together by rams (84) and lowered in steps by an elevator 81 so that other layers are superimposed until a cube of bricks is formed. The cube is moved on a conveyor (88) to a heat shrunk station 15 where the cube is enveloped in a thermoplastic bag and a heating hood 89 lowered about it to shrink the bag and seal it to the pallet and bricks. The heat of hydration thereafter cures the bricks.

Abstract: 1,249,655. Shaping by drawing through a die. BATTELLE DEVELOPMENT CORP. 29 Oct., 1968 [16 Nov., 1967], No. 51221/68. Heading B5A. [Also in Division B3] Elongated material, e.g. metal, polyethylene, is bent by pulling the material through at least one die whilst simultaneously subjecting the surface of the material to fluid hydrostatic pressure. A flat strip 32 is progressively bent into a V-section by pulling it through dies 12- 20 adjustably positionable on rods 45 inside a chamber 10 containing fluid, e.g. oil, gas, pressurized by a ram 52. The chamber 10 is sealed by 0-rings 43, 42 positioned in grooves in the end dies 12, 20. The openings 48 of the end plates 34, 36 of the chamber 10 may conform to the cross-section of the exiting and entering workpiece, sealing of the chamber 10 being effected by resilient strips (62, 64) (Fig. 2, not shown) bearing against the material 32 by the pressure of the fluid. The chamber 10 is preferably enclosed within a second chamber 56 also containing fluid under pressure. A light draw may be given to the strip 32 on passing through the last die 20. The initial threading of the strip 32 through the dies can be facilitated by using split dies (Fig. 4, not shown). The strip 32 may be formed into a L-, V-, U-, Z- or hut-shaped cross-sectional member. Alternatively, a tube can be bent into a star-like configuration using a mandrel, or a removable filler or metal core.

The bonding may be overall or in selective areas only. The aluminium may be bonded to paper, aluminium, woven glass fabric, woven cotton fabric, cardboard, a ureaformaldehyde resin, a phenol-formaldehyde resin or a polyimide. The tool is preferably a rotating friction wheel co-operating with a metal backing roll covered with rubber.

Abstract: 1343353 Fluidized beds GENERAL TIRE & RUBBER CO 5 Nov 1971 [9 Nov 1970] 51544/71 Heading F4U [Also in Divisions F2 and B5] Fluidized bed particles are removed from an extrudate 13 emerging, after heating or cooling, from a fluidized bed 1 by projecting a stream 19 of gas or steam and fluidized bed particles in a direction opposed to the direction of motion of the extrudate on to the surface of the extrudate at an angle of from 25 to 30 degrees to the extrudates major axis. The extrudate 13 is fed directly or via another fluidized bed (not shown) into a fluidized bed 1 containing glass balls 0À005 to 0À010 inches in diameter or sand and is fluidized by hot or cold air or steam 11. As the extrudate passes through exit passage 17 any adhering particles are dislodged and returned to the bed by impingement of particles drawn from the bed by the venturi effect of air from source 23 and directed through nozzles 29 in a frustoconical carrier 31.

Abstract: 1369435 Testing Piezo-electric transducers DEFENCE SECRETARY OF STATE FOR 27 Oct 1971 [30 Oct 1970] 51694/70 Heading G1U To test whether a Piezo-electric transducer TRANS (e.g. a vibration monitor in an aero engine) and its connecting leads are in working order, a voltage pulse is applied to the leads to shock-excite the transducer, and an indication is given if the transducer oscillates in response to the pulse. Preferably the voltage pulses are applied repetitively by closing a switch S 1  briefly once per cycle of an oscillator V.C.O. Immediately after the closing and opening of the switch S 1  another switch S 3  is briefly closed to short-circuit the transducer leads and remove any capacitatively - stored charge (which would give spurious results), and a further switch S 2  is then closed to connect the leads to a threshold detector Z.C.D. for the remainder of that cycle of the oscillator V.C.O. If the transducer is working properly, the detector output after each shock-excitation will be a train of pulses. A first counter (4-C plus BI S/R) produces an output in response to each train only if that train contains more than four pulses, and a second counter 16-C activates an indicator IND only if outputs are produced by the first counter in sixteen cycles of the oscillator V.C.O. The counters thus prevent spurious noise signals from giving a false indication. The oscillator frequency is preferably swept, under the control of a ramp generator V.R.G., over a range of frequencies corresponding to a sub-harmonic of the range of resonant frequencies of the tranducer.
