Title: Improvements in pistons
IPC: F02B75/38
Filed: 1927-12-09
Abstract: 300,808. Schweter, E. Dec. 9, 1927. Pistons; cooling; attaching to pistonrod.-In a piston for internal-combustion engines &c. of the type comprising two relatively movable parts pressed apart by spring pressure and adapted to yield under explosion or other pressure, a damping effect is produced by the use of springs of the ring type, or by liquid pressure, or by both. A single-acting piston comprises a head 17<11>, Fig. 6, movable on a part 16<11> secured to the skirt portion 15<11>, the parts being pressed apart by concentric springs 19<11>-22<11>, each comprising a number of undivided rings with bevelled engaging surfaces. Oil or other liquid under pressure admitted by a pipe 33<11> traverses the annular spaces between the springs and is discharged by a pipe 27". Relative movement of the piston parts is limited by a ring 18<11>. Alternatively, a single spring may be employed between the piston parts. A double-acting piston comprises heads 4<11>, Fig. 5, to which are secured extensions 3<11> sliding on guides 3<1> secured to collars 2" on the piston-rod. A single spring 6<11> of the ring type, or two springs, as shown, extend between the parts 3<11>. Packing-rings are provided between the parts 3<1>, 3<11>. Pressure liquid admitted by a pipe 7<11> passes to the space 8<11> and by the annular space between the springs 6" to the space 12<11>, from which it is discharged through a passage 13<11> to the annular space between the pipe 7<11> and the interior of the pistonrod. Alternatively, the ring springs may be replaced by a single helical spring, or by two or more helical springs, arranged either concentrically, or threaded together. Piston heads 21, Fig. 3, may slide on a middle part 17 secured to the piston-rod 16, the heads being acted on by springs 22 abutting on a cage 19 sliding in apertures in a partition 18. The springs may be of the ring type, or the piston may be damped by pressure liquid. The sliding surfaces of the ring springs may be formed with annular and oblique grooves for the admission of lubricant.

Title: Process for improving the octane rating of hydrocarbon  feedstocks
IPC: C07C7/13
Filed: 1972-07-20
Abstract: 1344594 Reforming; separating hydrocarbons by adsorption UNION CARBIDE CORP 20 July 1972 [21 July 1971] 33940/72 Heading C5E A process for improving the octane rating of a feedstock comprising saturated C 5  and C 6  paraffins comprises passing the feedstock into an adsorbent bed at 240-390‹ C. and 175-600 p.s.i.a. to selectively adsorb normal paraffins therefrom, desorbing normal paraffins from the adsorbent with a hydrogen purge stream and passing at least a portion of the mixture of hydrogen and desorbed normal paraffins through a reactor containing a zeolitic molecular sieve isomerization catalyst and a hydrogenation promotor at 240-390‹ C. The adsorbent used has a pore diameter of 4-6 Š and can be a zeolite A, R or T, chobazite, erionite, or mordenite. The isomerization catalyst can comprise a zeolite Y having a reduced sodium cation content and platinum or palladium as the hydrogenation promotor. The catalyst can contain a porous inorganic oxide as diluent or binder, e.g. oxides of Cr, Mo and W, silica, alumino, aluminosilicate clays, or co-gels of silica with alumina, zirconia, titania or thoria. A stream of C 5 -C 6  naphtha is passed into an adsorbent bed 18 of calcium zeolite A and the non-adsorbed branched-chain hydrocarbons are passed to a cooler 30 and separated at 32 wherein they are separated from the hydrogen stream 36. Whilst the bed 18 is used for adsorption, normal hydrocarbons adsorbed on the bed 22 are desorbed with a stream 52 of hydrogen which is passed in a direction counter-current to the feedstock during the adsorption stroke. At the start of the desorption the effluent is a mixture of normal and branched-chain hydrocarbons and is recycled via line 61. The ratio of hydrogen to hydrocarbon entering the isomerization reactor 20 is maintained within the range 2 to 30 by (a) passing hydrogen through line 54 at the start of the desorption or by (b) holding a portion of the hydrocarbon-rich desorbate in a tank 62 and then blending it with hydrogen or with hydrogen-rich effluent from the later stages of the desorption. The effluent from the reactor 20 is cooled at 70 and separated at 72 to provide a recycle hydrogen stream 74, containing some methane, ethane, propane and butane, and a stream 60 containing normal and isomerized paraffins which is recycled to the adsorbent bed 18.

Title: Data processing apparatus
IPC: G06F17/14
Filed: 1971-07-20
Abstract: 1328489 Digital computers; fast Fourier transforms WESTERN ELECTRIC CO Inc 20 July 1971 [21 Oct 1970] 33978/71 Heading G4A A data processor evaluates fast Fourier transforms. Fast Fourier transforms have been evaluated using cascade (or pipe-line) processors as described in U.S.A. Specifications 3,544,775 and 3,588,460 and the present apparatus uses similar processors in which a permutation of input data sequences is performed prior to processing. This permutated data is then applied in alternate subsets to each of the input terminals of a succeeding computation stage. It is stated that this improves the computational efficiency. In a first embodiment there is a cascade of modular computers 101-1 to 100-3 though the number of stages X depends on the number of samples N for which Fourier series cofficients are required, where N = 2x, which equals 8 in this case, as X = 3. Data is entered at terminals 101, 102 but by use of a delay 120-1 (e.g. a delay line or a shift register) and a switching network 110-1 (Fig. 3, not shown) both are dealt with together. The order of the samples is changed at each stage as can be seen from Fig. 4. The computers 100-1 to 100-3 are known (Fig. 2, not shown) and can perform addition, subtraction and multiplication on real or complex signals. In another embodiment (Figs. 6-8, not shown) only one input is used and in Fig. 9 (not shown) the units 101-1 to 101-3 have a single time shared computer unit using multiplexing. The fast Fourier transforms may be performed on bases 2 and 4 and it is stated that the operations described above could be performed on a general purpose computer, suitaly programmed, rather than in the described apparatus.

Title: Improvements in or relating to battery charging systems and to control relays and circuits for use in such systems
IPC: H02J7/14
Filed: 1927-12-19
Abstract: 305,335. Bucklen, H. E. Dec. 19, 1927. Systems for supplying consuming devices from variable-speed generators; charging batteries.-In battery charging systems employing a shunt wound generator, particularly when wind-driven, a protective relay with its winding in the field circuit controls the connections between one pole of the generator and the battery and a cut-out relay also controls the charging circuit. The circuit arrangement is shown in Fig. 9. A main switch 152 has one contact blade in the shunt field circuit and another in the charging circuit to prevent generation of excess voltage. The protective relay 150 is shown in Figs. 6 and 7. The winding 111 is on a core 110, with pole pieces 113, 114, which has pivot bearings 106, 107 on supports which carry an adjustable fixed armature 134. To the ends of the polepieces is secured aT-shaped bar 117 which carries two contacts 126, 127 adjustably mounted on a conducting rod 120. A spring 140, with an adjustable abutment 142, tends to hold the bar 117 against a stop 141, but so long as the shunt field circuit is energized the winding 111 holds the contacts 126 in engagement with contacts 128, 129 which are adjustably secured in sockets 130 on th eswitch base. The cut-out relay 151 is shown in Fig. 1 and' its connections in Fig. 5. It has a shunt winding 55 connected, in the open position of the cut-out, through contacts 45 and through an assisting series winding 77. When the main contacts 58, 59 close the shunt winding is cut out at the contacts 45 and the series winding maintains the charging circuit until charging stops; the switch opens before reversal of current. Both coils' arewound upon pole pieces 4 which are shouldered down and secured to a frame 1 by screws 2 so clamping laminations 21 lying transverse to the general plane of the magnet. The armature 23 is of laminations similarly arranged. It is carried by a contact lever 24 pivoted at 29 and having an extension 43 carrying a spring contact 45. A spring 39 tends to keep the contact 45 on an adjustable contact 46 and the main contact 58 and auxiliary contact 64 off their companion contacts 59, 70; a stop screw 36 determines the rest position of the parts. The auxiliary contact 70 is rotatably and longitudinally adjustable on the post which carries the main contact 59. The apparatus is housed in a grounded sheetmetal box with fuses, lamps 181, 182 and push buttons 180, 183 for testing purposes, ammeter 153, voltmeter 154 and push button 184.

[Also in Division G1] Apparatus for monitoring a machine by registering the time of occurrence of events in its working cycle comprises a cascade binary counter driven from a source 86 of clock pulses and having a predetermined number of stages, and series circuits 72 (76, 77) responsive to each counter stage for preparing a corresponding stage in each of a number of channels, each of which has an event controlled input terminal E1 (E2, E3) pulsed upon the occurrence of the event to which it is allocated to cause magnetic cores 85 (115, 116) responsive to the pulse to store data in any stage of that particular channel which has been prepared by the counter. An array 70 of three-apertured cores such as 85 are used to store the data. " Set " windings 73, 74, 75 in series circuit 72, for example, are contained in the left-hand apertures of the first column of cores; blocking windings 79, 80, 81 in series circuit 78 are wound in the centre apertures of the cores of channel 1 for example and the right-hand aperture of every core in channel 1, for example, contains an interrogation winding 122, 123, 124 in series and an individual read-out winding 130, 131, 132. Any number of read-out signals can be obtained from the prepared cores in a channel after its event has occurred by applying to its interrogation winding pulses successively alternating in direction because if one pulse reverses the flux direction in the third and fourth legs of a set core a read-out pulse is induced and as the next pulse will reverse the flux again another read-out pulse is produced and so on. The read-out output pulses may be fed to telemetering equipment. All stored data in channel 1 can be cancelled by applying a signal to a zero-set switch 110 in parallel with an electronic event switch Q3 and similarly for the other channels.
