Title: Liquid dispensing control apparatus
IPC: B67D7/22
Filed: 1966-05-05
Abstract: 1,146,524. Fluid dispensing apparatus, A. O. SMITH CORP. 5 May, 1966 [24 May, 1965], No. 19881/66. Heading A4T. In a control unit for operating the pump switch and resetting the computer of a petrol dispenser so that the switch is closed only after resetting the computer and the switch is opened only after resetting the control unit, a manual trip lever must first be moved to turn shaft 23 and pawl 22 which abuts and lifts pawl 24 on cam 19 out of notch 25 in a ratchet wheel 14 secured to a manual switch lever shaft 13 carrying a switch operating cam 9 and prevented from being turned by pawl 18 engaging the ratchet wheel. Spring 20 then rotates cam 19 which resets and connects the computer to the meter and shifts pawl 18 via cam portion 19<SP>1</SP> so that the switch shaft 13 and cam 9 are free for turning. The switch has a differential action and the switch cam 9 has a raised switch-off portion, an intermediate holding portion and a lowered switch-on portion. On turning cam 9 a switch operating cam follower moves off the raised and on to the holding portion during which, due to the differential switch action, the switch remains off and notch 25 is brought into position to receive pawl 24 again. On further turning the follow rides on to the switch-on position and energizes the pump for dispensing. At the end of dispensing, the switch lever is turned in the opposite direction and as the follower rides from the on portion to the holding portion, the switch and pump remain on and notch 25 engages pawl 24 to tension spring 20 as cam 19 is turned and held by pawl 18 engaging ratchet 14 and the computer is disconnected from the meter. On further turning, the follower rides off the holding portion on to the off portion to stop the pump. The control unit is then ready to start a subsequent resetting and dispensing.

Heading B8T. -A counter-pressure bottle filling head having a counter-pressure gas inlet valve, not shown, at the top of a hollow rod 8 of a liquid valve 10, includes a closure member 15 slidable about the rod 8 and, in the non-filling position, urged against a seat 23 by the attraction of permanent magnets 43 and 44 attached to the closure member and a fixed support 45 respectively. After supplying gas to the bottle via the hollow rod and apertures in a depending tube, not shown, the liquid valve is raised from its seat 24 by a spring, and the member 15 is forced downwardly by the liquid pressure to permit liquid to flow to the bottle. When the liquid reaches the level of the apertures in the depending tube, the gas pressure within the bottle and the attraction of the permanent magnets causes the member 15 to return to its seat and closes the liquid passage, thereby preventing the back flow of gas from the bottle. In the embodiment of Fig. 4 (not shown), the closure member 50 is downstream of the liquid valve 10 and comprises an annular permanent magnet which is urged towards a seating 53 on the valve rod by a permanent magnet 55 on the liquid valve head.

[Class 68 (ii).] Concrete piles are made in situ by driving a tube A with a shoe A<1>, and pouring a charge of moist concrete down it ; the tube is then vibrated vertically by a hammer striking upwards and downwards, so as to deposit and tamp the concrete, which is then rammed so as to spread it in the ground and form a lateral enlargement. The tube is then filled with concrete which is deposited and tamped as before. The ramming to form the enlargement may be done by the tube A, which is raised so that its lower end may be closed by a removable or other shoe, or by a monkey B. Steel reinforcements may be placed in the concrete, those at the lower end being such as to be displaceable as the enlargement is made. Similar enlargements may be made elsewhere in the pile. The lower end may consist of a pile of timber or reinforced concrete. In making piles in water-logged ground, the tube A is provided with a protective casing consisting of concrete pipe sections ; those at the lower end are split to enable the enlargement to be made. Piles thus made may be set so closely that the enlargements coalesce and form a subterranean raft with pillars forming a building foundation.

Abstract: 1352394 Aircraft fuel tanks VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER GmbH 19 April 1971 [30 Jan 1970] 20668/71 Heading B7W The position of the centre of gravity S of fuel in groups 1, 2 of tanks arranged on opposite sides of the aircraft centre of gravity is maintained within predetermined limits by means of a regulator 25 which controls the supply and removal of fuel in response to signals from tank content level measuring probes 3 mounted in each tank. Fuel is supplied to the tanks via valves 7, 8 from connections 9 (ground) or 9a (in flight) and removed by pumps 10, 11 which are connected to an hydraulic system via valves 19, 20. Deviation of S causes probes 3 to deliver differing signals to a Wheatstone bridge 33 incorporated in the regulator 25; an output signal is produced whose polarity depends on the direction of movement of S, and this causes a motor 36 to rotate a cam-shaft 37 and hence after the setting of one of two switches 28, 29. A switch 32 is closed during filling of the tanks from 9 or 9a, thus allowing the regulator signal to close one of valves 7, 8 until S has been brought back within its admissible limits; switch 32 is open while fuel is being supplied via pumps 10, 11 to the engines, so that now one of the valves 19, 20 can be actuated to reduce the speed of its corresponding pump so that it participates only partly (or not at all) in the total fuel delivery until the deviation of S is cancelled.

Title: Improved method for alkylating benzene
IPC: C07C2/68
Filed: 1946-07-11
Abstract: In the process of the parent Specification for continuous alkylation of benzene by normally gaseous olefins in the presence of aluminium halide in a plate-type column, alkylation proper is effected in a first stage wherein the reactants are contacted at room temperature or below, the product then being brought to boiling point to decompose poly-alkyl compounds without any separation thereof or further catalyst addition, poly-alkylated derivative separated after this treatment being recycled to either the alkylation or decomposition stage.  The two stages are effected in the same column, the olefin, e.g. butylene, entering the medial part thereof instead of the base as in the parent Specification, and the benzene entering partly at the top and partly at the centre.  The upper part of the column is charged with a low boiling compound such as butane which touches only the upper plates at about 30 DEG  C.  This butane may be that contained in the olefin feed.  The lower part of the column is at about 90 DEG  C. The poly-alkyl benzenes are returned to the top or centre of the column.  The Specification as open to inspection under Sect. 91 is not limited to the use of a plate-type column and comprises examples using a vat for the alkylation followed by heating in the same vat or a steam heated coil.  This subject-matter does not appear in the Specification as accepted.
