Title: A process for separating a mixture into components by means of a zeolitic molecular sieve sorbent
IPC: B01D15/08
Filed: 1958-06-26
Abstract: <PICT:0826449/IV (b)/1> A hydrocarbon which can be adsorbed on a zeolitic molecular sieve is separated from a hydrocarbon not so adsorbed by contacting a mixture thereof with a composite of a zeolitic molecular sieve with a binder at a superatmospheric pressure which is from 1.5 to 20 times the desorption pressure, which is at least 1 atmosphere absolute, the temperature during adsorption and desorption being at least 200 DEG  C.  The process is preferably applied to the separation of normal from non-normal hydrocarbons, e.g. branched chain and cyclic hydrocarbons, in which case a 5 sieve is used. Adsorption may be effected at 1.5-100 atmospheres absolute and desorption at 1-20 atmospheres absolute.  The sieve binder may be a clay or alumina; the adsorbent may be used in a fixed, fluidized or moving bed.  In a preferred embodiment the mixture is fed by line 211 to adsorber 201 which contains a fluidized bed of a zeolitic composite fluidized by an inert gas introduced by lines 212 and 215.  Suitable inert gases include helium, hydrogen, nitrogen, methane, argon, flue gas (scrubbed to remove reactive impurities), ethane and propane and may contain a small amount of adsorbed hydrocarbons.  The zone 202 prevents the hydrocarbons filtering back and escaping with solids.  The gases leave by cyclone 204 and non-normal, unadsorbed hydrocarbons are recovered, e.g. by absorption in absorber oil, by adsorption on activated charcoal or by condensation, and the inert gas recycled by line 215.  Solids are removed by passage 216 into riser 210 and carried upwards by gas escaping into riser 210 or injected gas or other mechanical means to stripper 205 fed with inert gas by line 219.  Gases leave by line 220 and cyclone 206 for recovery of desorbed hydrocarbons by condensation in condenser 224 and separator 225, inert gas being recycled.  Solids are returned to the adsorption zone in batches by way of repressurizing chamber 209.  Adsorption and desorption may be carried out at temperatures within 50 DEG  C. of each other and preferably at the same temperatures to avoid heating and cooling of the sieve.

Title: A battery charging and discharging circuit
IPC: H02J7/00
Filed: 1959-06-18
Abstract: 887,855. Charging and discharging batteries. ULMER, L. June 18, 1959, No. 20981/59. Class 38 (4). In an arrangement whereby a battery is divided into two or more parts, B1, B2, each in series with a resistor R1, R2, which parts are charged in parallel and discharged in series, the arrangement allowing the use of a charging generator voltage approximately equal to that of a load, the resistors absorbing the voltage difference between the battery and generator and battery and the load, respectively, thermistors or semi-conductors having negative temperature-resistance coefficients are substituted for the ohmic resistances previously used. A load U may be fed from a series circuit of the batteries B1, B2 and thermistors R1, R2 on closing a switch I, which energizes relays Da, Db. When the generator G is also connected to the load through a relay E, a relay Ca is energized, which releases relays Da, Db, thus connecting the battery in parallel. An overload on the generator will operate a relay Cb deenergizing Ca and re-energizing relays Da, Db, thus reconnecting the batteries in parallel. Carbon resistors may be connected in series with the thermistors. The arrangement is particularly applicable to batteries of the silver zinc type which may be used in aircraft for an emergency supply. The resistance of the thermistors, alone or in combination with a carbon resistor, should be preferable equal to the internal resistance of a battery when charged or half the internal resistance when discharged.

Title: Improvements in or relating to automatic weighing apparatus
IPC: G01G19/04
Filed: 1929-07-09
Abstract: 339,934. Manufacture d'Horlogerie de Bethune, and Armagnat, P. J. July 9, 1929. Weighbridges.-An automatic travelling-poise weighing-apparatus of the type wherein the load is carried on to the weighing scale by means of an electrically-driven truck is provided with a device whereby the truck on arriving on the weighing scale is made to switch off the truck's driving motor in order that the truck may not run past the scale unweighed, and automatically effect the actuation of an operation-initiating mechanism whereby the weighing process is started, means being provided for restoring the current through the driving motor whereby the truck is restarted and clears the weighing scale for a new weighing operation. The truck in running on to the weighing scale closes the circuit of an electromagnet 21, the armature of which consequently presses a strap 23 against a wheel 15 which is thus caused to lag behind a continuously-rotating shaft 11 to which it is attached by a spring 18. A ball 16 loosely carried by the wheel 15 thereupon wedges between a cam 13 and a stationary cup wheel 14 which is consequently clutched to the shaft. A projection 20 on the cup wheel depresses levers 28, 24 provided with mercury contacts 25 and breaks the circuit of the truck's driving motor thereby bringing the truck to rest on the weighing platform. The projection 20 also rocks a lever 19 which in turn raises a release lever 1. The rise of the release lever starts the travelling poise mechanism, and the weighing operation is completed in known manner whereupon the lever 1 falls and displaces a lever 48 so as to interpose a ball 43 between a stationary abutment 36 and the flange 41 of a sleeve 32. The sleeve 32 is normally caused to reciprocate by the action of a continuously-rotating arm 31 upon a notch 38 in the sleeve. The interposition of the ball 43 however prevents the sliding movement of the sleeve and causes the arm 31, together with its shaft 30, to move to the left into engagement with an arm 46 which is thereby given a rotation and resets the weighing mechanism in known manner. The final movement of the arm 46 withdraws the ball 43 from its interposing position. The shaft 30 when moved to the left into its resetting position brings a cam 53 into engagement with a rocker 52 and by-raising the rocker causes a pin 56 to raise the contact lever 24 and again supply current to the driving-motor of the truck which then runs off the weighing platform, at the same time de-energizing the installation in its initial position.
