Title: Improvements in control circuits for magnetic drum registers
Inventor: BEAUFOY RAYMOND
IPC: G11B5/02
Filed: 1963-08-09
Abstract: 1,058,978. Magnetic drum stores. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Aug. 10, 1964 [Aug. 9, 1963], No. 31603/63. Heading G4C. [Also in Division G3] An auxiliary magnetic storage drum D is phase controlled in relation to a main clock system MS by means of an eddy-current brake EB so that data is read out from the drum n-¢ main clock periods after writing, and is retimed by means of a toggle controlled by a main system clock to afford exactly n clock periods delay. The brake does not come into operation until the drum has nearly reached correct speed, since an A.C. signal from track CT1 on the drum does not pass through highpass filter HPF until then, to open gate G2. Then a toggle MB, which is controlled by timing pulses TSM, TSA from main system and drum and which, at synchronism, is operated for 50% of the time, can pass a signal to integrator 12 to control the brake. Deviations control the on/off ratio of MB and thus maintain synchronism. A further toggle MF acts as safety device should the drum speed greatly exceed the desired clock rate. The retiming circuits RC and RT are illustrated in Fig. 9 (not shown) and transistor circuits for other units are also illustrated.

Title: Carbonators
IPC: C02F1/68
Filed: 1973-07-03
Abstract: 1441658 Carbonating liquids STRENGER ASSOCIATES INC 3 July 1973 [20 July 1972] 31646/73 Heading B1C A water carbonator 16 comprises, in the direction of water flow, a first stage 72 in which CO 2  is drawn from a source at lower pressure than that of the water by aspiration into the water and partly absorbed therein, and a second stage 74 in which the water with partly absorbed CO 2  is accelerated, to decrease static pressure and increase turbulence, so that the surface area of the water exposed to the CO 2  is increased to achieve substantially complete CO 2  absorption. Preferably, the water pressure is 90-95 psi, the CO 2  is 2-5 psi less than the water pressure, and the water temperature is between 32-40F. The stage 72 comprises an annular chamber 88 receiving CO 2  through an entry port 68, an inner chamber 82 receiving CO 2  from the chamber 88 through radial ports 90, and axial water flow passages 78 communicating with a water inlet port 52 and each intersecting at least one radial CO 2  aspiration passage 80. The stage 74 comprises a conical chamber having a wall 92 tapering to a throat 94 which communicates with a collection chamber 96. The taper angle of the wall 92 is preferably less than 45. The cross sectional area of the water inlet port 52 exceeds the total cross sectional area of the passages 78 which in turn exceeds the cross sectional area of the throat 94. In operation, water passing through the passages 78 draws CO 2  radial inwards and outwards respectively from the chambers 88, 82, the entrainment of CO2 molecules causing water flow turbulence and part CO 2  absorption. Water streams ejected from the passages 78 are impinged against the chamber wall 92 and are then combined at the throat 94 to enter the collection chamber 96, the acceleration towards the throat causing decreased static pressure and increased turbulence. In the arrangement of Fig. 1, water from a tank 18 is pumped at 20 through a cooler 22 to a line 32 having carbonators 16 disposed in parallel. Pressure in the line 32 is determined by a pressure regulating valve 36 relieving to atmospheric pressure. As alternatives, the pump 20 may be disposed downstream of the cooler, and the latter may cool the water whilst in the tank. The valve 36 and a CO 2  pressure regulating valve 40 are operatively interconnected. The outlet from each distributor comprises a push button opened faucet 52 which may be fixed directly to the carbonator body. The cooled water and CO 2  may be fed to the carbonators through flexible lines. Cooled pressurised water for the carbonator may be provided from a coil in, or in the wall of, a conventional refrigerator.

Filed: 1971-07-07
Abstract: 1334909 Stud driver O BILZ 7 July 1971 [12 Aug 1970] 31823/71 Heading B3N A stud driver comprises a shaft 35 adapted to be rotated in one direction and to be reciprocated in its axial direction and a collet connected to the shaft and comprising a jaw housing 4, elongate jaws 8 having internal thread sections in their inner front ends and longitudinal grooves in their peripheral outer sides, locking balls 7, 8 partly projecting into said grooves and movable by the housing along said grooves, means for shifting said jaws and said housing axially relative to each other from a first position in which the threaded ends of the jaws are biased together and a second position in which the said ends are biased apart. In operation a stud 36 is pushed into front part 9 of guide sleeve 19 and the stud is then presented to a tapped hole and shaft 35 driven. Initially the stud screws into the jaws until it reaches a stop 6. Thereafter the stud is screwed into the tapped hole a preset distance, whereupon the forward movement of shaft 35 is stopped. Further rotation of shaft 35 causes the stud to be driven further into the tapped hole, pulling the jaw housing 4 therewith until interengaging drive cams 12, 13 are disengaged and the rotation of the collet is stopped. While continuing rotation shaft 35 and casing 1 are retracted causing a pressure ring 10 to be retracted and screws 15 to be moved toward the rear along peripheral groove 21 and then take along jaw housing 4. This will force balls 5 out of the recesses 8<SP>1</SP> and into annular recess 11 and will be shifted at the same time along grooves 8<SP>11</SP> to a position behind pivot pin 14. The jaws 8 will thereby be pivoted about this pin and the threaded front ends will be opened to disengage the stud. During this movement return spring 3 is compressed and this serves to retract the open jaws 8 from the stud. Fitting another stud into casing 16 moves it backward relative to jaw housing 4 and allows the jaws to return to their initial position. In a modification, Fig. 5 (not shown), return spring 3 is replaced by a compression spring positioned between the threaded ends of the jaws and a bushing that replaces guide sleeve 19. A further modification, Fig. 6 (not shown), has an adjustable torque control clutch and a resilient pressure-responsive length compensating device.

Title: A method and apparatus for the production of lightweight aggregate
IPC: C04B20/06
Filed: 1954-11-04
Abstract: 786,500. Porous compositions. SOUTHERN LIGHTWEIGHT AGGREGATE CORPORATION. Nov. 4, 1954 [July 20, 1954], No. 31902/54. Class 70. [Also in Groups XI and XII] A lightweight aggregate is prepared by passing the raw material, e.g., clay, shale, or argillaceous or non-argillaceous slate, downwardly through a rotating inclined kiln to be heated by combustion products prior to exposure near the lower end of the kiln to a short concentrated flame from burner apparatus, to cause it to expand, and passing a substantially restricted flow of secondary air over the material discharging from the kiln to prevent agglomeration of the particles of the aggregate and to produce a reducing atmosphere within the kiln. Apparatus for carrying the process into effect may comprise an inclined rotating cylindrical kiln 10, (see Group XII), heated by a pair of burners 30, 31 (see Group XI), adapted to produce a short high temperature flame within the lower end of the kiln, the combustion gases from which pass through the kiln to a stack 12. Crushed raw material is fed via a shoot 19 into the upper end of the kiln 10 to be heated to about 600‹ to 1200‹F. in a first zone extending for about 25 per cent of the length of the kiln, and to about 1700‹ to 1900‹F. in a second zone extending for about two thirds of the kiln length. The material then passes into the intense heating zone of the burners 30, 31 to be heated quickly to about 2200‹ to 2250‹F. and thereby expanded, and at the outlet end of the kiln it is cooled by the incoming combustion air and is discharged by a shoot 41. The burners 30, 31 are supplied with pulverulent coal and the ash thereof is stated to be incorporated in the outer layers of the aggregate particles and to assist in preventing agglomeration of the latter. Secondary air enters the lower end of the kiln and its flow is restricted by individually pivoted slats 92 suspended beneath a platform 40 so as to be displaceable by the material discharging through the shoot 41.

Title: Improvements in or relating to the treatment of mixtures containing soap and neutraloil or fat, for the purpose of separating the constituents thereof
IPC: C11B13/02
Filed: 1929-10-22
Abstract: Mixtures of soap and neutral oil or fat such as are obtained in the sludge of the alkali purification of oils, are treated with solvent to extract the oil, and the residue is acidified and distilled to recover residual solvent and obtain fatty acid.  In examples: (1) 500 kg. of soap containing 40 per cent of neutral oil and obtained by neutralizing ground-nut oil with sodium carbonate solution, is treated at 30 DEG  C. with 3000 kg. of benzol and allowed to settle. The upper layer is decanted and distilled to recover the venzol and the oil.  The lower layer consisting of soap and residual extract is further treated with and decanted from benzol, and the final mixture of soap and residual benzol is dissolved in warm water, acidified with sulphuric acid, heated and stirred until the benzol is distilled off, allowed to settle, and the acid liquor and fatty acid drawn off separately.  (2) The solution obtained by extracting rape-seed with benzol is deacidified at about 30 DEG  C. by caustic soda solution, and the sludge obtained is further treated as in Example 1.  The Specification as open to inspection under Sec. 91 (3) (a) describes generally the separation of substances from mixtures containing soap by acidifying to convert the soap into fatty acids and distilling off substances more volatile than the fatty acids, e.g. water or pleasant or unpleasant smelling substances.  This subject-matter does not appear in the Specification as accepted.

[Class 106 (iv).] A device for indicating to a machine-operative or other workman the efficiency with which he has worked comprises a drum rotatable in accordance with the amount of work accomplished, a chart having a number of percentage scales mounted on the drum, and a stationary time scale or time driven pointer co-operating with the chart to permit the percentage of work done to be read off or directly determined. In one form of construction, Fig. 1, the chart with curves appertaining to different working speeds and outputs is mounted on a drum 1 actuated in a step-by-step manner through gearing from a member 19 receiving impulses from the machine &c. under observation. Parallel to the axis of the drum a scale 2 is mounted graduated in hours and minutes with omissions representing intervals in the working time. In a modification shown in Fig. 6, a clockwork mechanism 11 drives a screwed spindle 13 carrying a nut 14 on which is mounted a pointer 10 co-operating with the drum chart. In the above described constructions to utilize the same chart for different working speeds the scale 2 in the first instance is made of uniformly extensible material being fixed at its lower end to a block 24 and attached at its upper end to an adjustable clamping nut 22. In the second form the pointer 10 is loosely carried by the nut 14 and has an extension 15 engaging a pivoted forked member 16 the inclination of which can be adjusted with respect to the screw 13 so as to vary the displacement of the pointer. In another construction shown in Fig. 7 when the machine is working at the prescribed efficiency the drum appears stationary. For this purpose a differential gear is provided to rotate the drum one member of said gear is advanced by impulses from the machine and the other member is driven in accordance with the elapsed time. The chart for this type of apparatus is formed with lines radiating from a point. Instead of a scale and percentage chart a fixed pointer and a chart representing the number of parts to be completed at each position of the drum may be provided.
