Title: Fluid delivery control and registration system
IPC: G07F13/02
Filed: 1974-09-11
Abstract: 1479674 Dispensing liquids VEEDER INDUSTRIES Inc 11 Sept 1974 [12 Sept 1973] 39616/74 Heading A4T A fluid delivery registration system for use with a plurality of fuel pumps 10 comprises pulse generating means 110 for transmitting trains of pulses indicative of the amount of fuel being delivered from each pump 10, a storage memory circuit (36) (38) Fig. 1C (not shown), for storing data relating to each delivery from each pump 10 in accordance with the pulse trains, register means (16), Fig. 10 (not shown), for registering each set of delivery data from the memory circuit (36), (38), and manually operable register control means (43), (Fig. 1C), for selectively operating the register means (16) to register any chosen delivery. In a self-service situation, when a pump 10 is selected and a button 62 is pressed to request activation of the pump, an appropriate button 60 at a central control point is pressed, enabling dispensing to be initiated. Power is supplied to an electric reset means 92, and on positioning a handle 90 in a dispensing position, volume and cost registers 93, 94 are reset to zero. Power is then supplied to a delivery pump motor 98, whereupon a signal is transmitted via a line 106 to clear the corresponding memory section in one of the two memory circuits (36), (38) provided, the signals from each pump 10 being scanned by a central scanner (107) Fig. 1B (not shown) connected to the circuits (36), (38). As dispensing proceeds, the pulse generator 110, driven by the cost register 94, transmits signals via a lead 112 to a pulse scanner (114), (Fig. 1B) at the central control. One of the memory circuits (36), (38) is actuated to accumulate the cost of the fuel delivered in a memory (34). A lamp (not shown) is provided to indicate which memory circuit (36), (38) is dealing with the particular dispensing operation, and provision of the two circuits enables data from successive dispensing operations to be retained. At the end of the dispensing operation, single shot means 120 provides a pulse which acts to switch to the other memory circuit for the following dispensing operation. When the dispensing operation is complete, the data stored in the memory (34) is used to actuate the register (16) to display the price to be paid by pressing a respective button (44), of the control means (43), (Fig. 1C) appropriate to the pump 10 in question, and a button 133 or 135 for the appropriate memory circuit (36), (38), a further button 143 being provided for subsequently clearing the memory. During dispensing signals from the scanner 114 are also transmitted to a totalizer circuit (190) having an eighteen digit memory (192) for accumulating the total cost of each of e.g. three grades of fuel dispensed by all of the pumps 10 over a period e.g. a day or shift, a manual reset button (280) being provided for clearing the memory (192).

Title: Sealed movable joints
IPC: B63C11/10
Filed: 1966-09-09
Abstract: 1,141,403. Diving suits. LITTON INDUSTRIES Inc. 9 Sept., 1966 [10 Sept., 1965], No. 40501/66. Heading B7U. [Also in Division F2] A sealed joint between two relatively movable hollow members 10, 12 in a diving or space suit comprises a resilient sealing ring 64 mounted on one of the members for sliding contact with, and urged by deformation towards, a sealing element 58 on the other member, a diaphragm 90 or other resilient structure supporting the sealing element such that the pressure difference in one direction across the seal will deform the diaphragm to cause the sealing element to move away from, but not out of contact with, the sealing ring. The sealing ring 64 may be made of P.T.F.E. and is provided with a rubber back-up ring 68. The thrust load is carried by a ball bearing 36. As the load increases all the parts tend to deform and the increase in sealing force is relieved by the diaphragm portion 90. When the suit is used for deep-sea diving, the pressure on the outside 48 is greater than that on the inside. A variation in pressure difference across the diaphragm 90 tends to cause the sealing element 58 to deflect away from the sealing ring 64 but this movement is followed by the sealing ring under the influence of the rubber back-up ring 68 which is deformed by the pressure acting upon its surface area 70. During assembly, the rubber back-up ring 68 is compressed by bolts 67 causing it to bulge as at 66. When the suit is used for space environment, the surface area 70 of the rubber back-up ring 68 is in communication with the interior of the suit; the diaphragm 90 is again arranged so that the pressure difference tends to deflect the sealing element 58 away from, but not out of contact with, the sealing ring 64.

Title: Process for the recovery of pure isophorone from reaction-mixtures by distillation
IPC: C07C49/20
Filed: 1961-11-23
Abstract: <PICT:1000574/C2/1> In a process for the separation of isophorone from the condensation products of acetone, the unreacted acetone is removed from the products by distillation under a pressure falling within the pressure range employed in the condensation (approx. 30 atmospheres).  The liquid residue from this pressure-distillation is then distilled, preferably at reduced pressure, to obtain purified isophorone.  A mixture of 80% acetone, 20% water and 0.04% of alkali as catalyst is continuously fed into the reactor 7, wherein the condensation of some of the acetone takes place under a pressure of approx. 30 atmospheres and at a temperature of 200-235 DEG  C.  The reaction product is fed via line 1 into a fractionating column 2 and undergoes fractionation under a pressure of approx. 30 atmospheres. An azeotropic mixture of acetone and water distils over at the top of the column, the vapours being condensed in water-cooled condenser 4. The condensate is returned to the feed to the reactor via line 5. The high temperature of condensation results in steam being generated from the cooling-water in condenser 4, and this steam may be used elsewhere in the plant as a heating medium.  The residual mixture in the column flows into the sump 3 and separates into two phases, the upper one being substantially composed of isophorone and the lower one being an aqueous liquid containing the alkaline catalyst.  The upper phase is continuously withdrawn from the sump and the isophorone isolated by distillation under reduced pressure. The lower phase is recycled to the column via line 6 to maintain a concentration of the alkaline catalyst in the lower half of the column, thus ensuring decomposition of mesityl oxide and xylitones present in the reaction mixture into acetone and isopherone.
