Title: Ion exchange materials and the preparation thereof
Inventor: PIRET JEAN
IPC: B01J39/08
Filed: 1964-03-13
Abstract: The invention relates to crystalline grains of an acid salt of a polybasic acid selected from phosphoric, vanadic, tungstic, phosphotungstic, molybdic and phosphomolybdic acid and of a metal selected from titanium, zirconium, tin and niobium.  The crystalline grains are prepared by heating a compound of the metal with sulphuric acid of density 1.84g./cm.3 to a temperature above 120 DEG  C. until a clear solution is obtained, allowing the solution to cool, adding the polybasic acid in anhydrous form to the solution, heating the resulting mixture to a temperature between 100 DEG  C. and 200 DEG C. until a gel is obtained, and recovering crystalline grains from the gel.  The first heating stage takes place at a temperature preferably between 120 DEG  and 180 DEG  C., the cooling between the heating stages may be to ambient room temperature, and the second heating stage takes place at a temperature preferably between 150 DEG and 170 DEG  C.  A solubilizing agent, for example ammonium sulphate, may be added to the sulphuric acid.  The crystalline grains are recovered from the gel by conventional methods, for example filtering, washing, and drying.  Alternatively, crystalline grains may be prepared directly from the amorphous salt by mixing grains of the amorphous salt with an aqueous solution of sulphuric or nitric acid and of the polybasic acid from which the amorphous salt is derived, the resulting mixture being heated to a temperature between 50 DEG  and 80 DEG  C. until crystalline grains are obtained.  The crystalline product may have a grain size of 1.5 mm. or more.  The crystalline grains, which have enhanced ion-exchanging properties compared to those of the corresponding amorphous material, may be used as ion-exchange materials.

Filed: 1964-03-13
Abstract: <PICT:1103276/C1/1> In the manufacture of flat glass during which the glass is advanced in ribbon form on a bath of molten metal, the transfer of impurities in the molten metal to the interface between the glass ribbon and the molten metal from parts of the bath surface which are exposed to the atmosphere ove the bath is impeded preferably by one or more physical barriers, thus reducing the uptake of contaminants by the bottom surface of the glass ribbon.  The barriers are in the form of screens 12 arranged vertically in the bath 3 on either side of the glass ribbon 11.  They may be of denser or lighter material than the molten metal (e.g. tin) of the bath, and may be made of carbon, or refractory material or spheroidal graphite iron.  The screens 12 may extend from the floor of the bath to the surface of the molten metal, or extend from the floor to just below the molten metal surface, or they may float with their upper edges above the surface and their lower edges above the bath floor.  They may also be supported in position by arms located in the side walls of the tank structure above the bath, see Figs. 2a to 2c (not shown). The screens may also be in the form of partially submerged boats or V-shaped channel members. The screens are maintained spaced apart from the glass ribbon.  In an alternative embodiment a pocket 16 (Fig.3) may be built into the tank structure so that an additive may be put into the molten metal as in Specification 1,025,583.  Screens 12a seal off the pocket 16 from the rest of the bath.

Title: Improvements in or relating to electric motor controllers
IPC: H02P3/08
Filed: 1933-04-13
Abstract: 418,441. Master control of D.C. motors. RANSOMES, SIMS, & JEFFERIES, Ltd., and GILBERT, W., Orwell Works, Ipswich, Suffolk. April 13, 1933, No. 11089. [Class 38 (iii).] Regenerative and non-regenerative braking.- An electric motor driving, for example, a trolly bus is speed controlled by a main control element, and subjected to braking by operation of a separate and independently operated brake control element, upon the operation of which the motor is adapted to be subjected to regenerative braking, and, when it has slowed to a given speed, to be subjected automatically to rheostatic braking. Operation of an accelerator pedal causes the sequential closure of contacts C1-C6, and the sequential opening of contacts C7-C12, whereby the vehicle motor A is connected to the supply and accelerated by the exclusion of armature resistance R, the shunting of its series field by resistance r<1>, and the inclusion of shunt field resistance r<2>-r<7>. Return of the pedal causes regeneration, and if it is returned to its " off " position the vehicle coacts with the shunt field SS weakly excited through resistance rs from the motor. If a brake pedal is depressed it closes first contacts bc1, bc2, and then bc3. A contactor N is therefore closed, together with its contacts N1, N2, so that the shunt field SS is connected directly across the supply. A potential coil rpw of a reverse current relay is connected across the motor, and the contactor G is closed to shunt the series field. If the motor voltage is sufficiently high the reverse current relay closes contacts rc1 whereby the line contactors and a resistance contactor are closed to connect the motor to the-supply with the armature resistance excluded. The motor is thus regeneratively braked, the energizing circuit of the contactor G being interrupted by an over-current relay OC if the regenerated current is excessive, to strengthen the series field, and reduce the current. When regenerative braking ceases the reverse current relay rpm, rcw, opens the contacts rc1, and closes rc2 thereby causing the disconnection of the motor from the supply, and the energization of a contactor H which connects a portion of the resistance R for rheostatic braking. The final part of the movement of the brake pedal may apply mechanical brakes. Reference has been directed by the Comptroller to Specifications 411,482 and 411,541.

As shown, the speed governor weights 28 are connected to the control member 11 via a bellcrank (61), Fig. 2 (not shown), the force of the governor spring 51 being applied to the weights via a flange 42 at one end of a tubular member 43 and an overfueling start spring 41 (fully compressed when running). As load increases and speed falls tube 43 moves to the right eventually drawing a spring carrier 81 to the right via lip 44 and fingers 83 to bring flange 116 of a thrust ring 114 into contact with rollers 117 on flyweights 102 thus preventing further rightward movement of the tubular member 43 and thus limiting the fuel delivery. Further speed decrease under loading, below a predetermined level decreases the centrifugal force of the flyweights 102 to a value at which the spring 107 is able to move the thrust ring 114 to the left against spring 51 thus decreasing fuel delivery.
