Title: Mass transfer apparatus
IPC: B01D3/22
Filed: 1982-01-04
Abstract: Mass transfer apparatus, e.g. distillation/rectification column which is divided so that the vapour flow is in two streams each in a separate zone 14 or 16, and wherein in each zone the liquid/vapour contacting stages 14A, 14B etc, 16A, 16B etc have an inlet 24, 24' disposed on opposite sides of an active area 26, 26' but to the same side of the division 20 and such that liquid flow from the inlet across the active area to the outlet is generally rectilinear and parallel to the plane of the division, the locations of the stages 14A, 14B etc in one zone being staggered axially relative to those of the stages 16A, 16B etc in the other zone along the column and the liquid from each outlet being directed to an inlet of the next lower stage in the column whereby the liquid flow down the column is directed alternately from one zone to the other as it is passed successively from stage to stage down the column. <IMAGE>

Title: Rotary positive-displacement pumps
Inventor: NOBLE TERENCE EDGAR
IPC: F04C2/08
Filed: 1982-02-04
Abstract: In order to reduce pressure pulsations produced in a gear pump as each inter-tooth space (44) of the gears (36, 37) comes into communication with the inlet and outlet ports (38, 39), enlargements (41, 42) of the gear chamber (31) comprising parallel bores (32, 33) are produced by drilling a third bore (40) whose axis is co-planar with but skewed relative to the axes (34, 35) of the other bores (32, 33), the angle of skew being such that each gear rotates half a tooth pitch from where one end of one of its inter-tooth spaces starts to communicate with the inlet or outlet port to where the other end does so. <IMAGE>

Title: A clip for chain links or a tenter chain
IPC: D06C3/04
Filed: 1982-02-24
Abstract: Edge strip 2 of fabric web 1 is pressed firmly against clip table 3 by one or more rollers 9 carried on roller shaft 8, which is seated in free ends of swivel arms 7 of U-shaped support 6. Said support 6 is seated swingably on clamping member shaft 5 which is held between ends of supporting arms 4 attached to table 3. Feeler nose 10 of support 6 may be actuated so that rollers 9 selectively occupy clamping position (shown) or else are raised above plane of table 3 to permit release and renewed reception of edge strips of fabric web.   Use of rollers 9, instead of previously known sharp clamping edges, avoids damage to and reduces marking of edge of fabric web. <IMAGE>

Title: Fuel gasifying burner
Inventor: MIYAHARA KINGO
IPC: F23D11/44
Filed: 1982-04-19
Abstract: A burner includes a combustion device (8) located below a gas generating member (1) housing a fuel supply device (7), a plurality of combustion members with flame apertures (5) are arranged on either side of the member (1) substantially in the same horizontal plane (2) or in a plane below that of the gas generating member and maintained in communication with member (1). The combustion member may be of annular form and located below member 1, or of a doughnut shape. Actuation of device (8) first allows member (1) and members (2) to be preheated to a fuel gasifiable temperature and then permits member (1) to be heated by flames formed by combustion of gasified fuel ejected through the apertures (5) of the combustion members. <IMAGE>
Patent GB-2121548-A (GB)
Title: Peak voltage detector circuit
Inventor: ARDLEY RAYMOND
IPC: G01R19/04
Filed: 1982-05-21
Abstract: In order to obtain a fast response without introducing errors due to overshoots in a peak voltage detector circuit of the kind in which an input signal applied to an input terminal (6) is fed to a capacitor (9) via the non-inverting input (7) and output (5) of a difference amplifier (1) the output circuit (3) of which is constituted by a unidirectional current path and the inverting input (10) of which is fed from the capacitor, the signal path from the non-inverting input (7) to the capacitor (9) is shunted by a diode (14) which conducts current in the same direction, as seen from the capacitor, as does the output current path of the amplifier. The result of this is that, when a positive pulse which is sufficiently steep to demand a rate of change of potential at the capacitor (9) which exceeds the slew rate of the combination of the amplifier (1) and the capacitor (9) is applied to the input terminal (6), the capacitor (9) is charged immediately to one diode threshold below the input signal via the diode (14), the amplifier then merely having to increase the capacitor voltage by one diode threshold. Thus, provided the open-circuit-output slew rate of the amplifier (1) is kept sufficiently high, the slew rate of the combination of the amplifier (1) and the capacitor (9) can be appreciably less than would otherwise be required, thereby reducing the likelihood that overshoots will occur. <IMAGE>

Title: Packaging film dispensers
Inventor: ORPEN KENNETH S E
IPC: B65H75/08
Filed: 1982-05-21
Abstract: In a packaging film dispenser a roll of film mounted on a core tube is supported to rotate as film is dispensed and an adjustable braking effort is applied in the radial direction to the inside of the core tube to enable tensioning of the film paid off from the roll. The braking means (30) may include two coacting brake members (35 and 32), member (35) being made fast frictionally to the inside of the core tube for rotation therewith by an expansible friction member (31) carried by the member (35). Brake member (32) is fixed against rotation to a stationary part (14) of the dispenser. A handle (15) of the dispenser is effective to expand the friction member (31) into tight contact with the core tube and to control the braking effort established by the coacting brake members (32,35), and handle (16) is for manipulating the entire dispenser. Alternatively, member (32) may be omitted and member (35) may be non-rotatably held in the dispenser with friction member (31) or a flexible and expansible skirt as part (35b) adjustably bearing against tube to control rotation thereof. The roll may be held between two horizontal arms of an upstanding three-sided frame, the upright arm carrying the handle (16), the handle (15) and the braking means (30) being carried on the upper horizontal arm, and the plug (19) on the lower horizontal arm. <IMAGE>

Title: Manipulating legs of a self- elevating platform
Inventor: AMIEL PIERRE
IPC: E02B17/00
Filed: 1982-08-23
Abstract: The upper section of each leg 11-13 of a self-elevating platform 5 is cut as a single portion so as to limit the height of the remaining leg portions to an admissible value for towing the platform structure in a barge configuration. After cutting, shoes 161-163 grip rack teeth on each leg and raise the cut portion by hydraulic jacks. Then one shoe 161 acts as a pivot and the portion is swung arcuately by a deck crane 34 and cable 36 for lateral displacement. This frees the space above the corresponding remaining leg portion, and the cut portion is stored on the caisson of the platform structure. The leg is reassembled after a displacement in the opposite direction of the cut portion and positioning the latter above the corresponding remaining leg portion and after joining the two leg portions. <IMAGE>

Title: Pipe joints
Inventor: SCRAGG FREDERICK
IPC: F16L41/02
Filed: 1982-10-13
Abstract: A pipe joint has a hollow fluidtight core (10) with at least one bore (12) extending therethrough. A shell (24) having at least three relatively pivotable parts (eg 28,29) which are connected to one another on one side of the joint by a single pivot (38) and securable to one another on the opposite side by a single fastening (48) can be fastened around the core. The edges of adjacent parts each have a part-circular recess which, when the parts are brought together, form a circular aperture positioned to overlie the opening of each bore. When the shell is closed on the core, tightening of the fastening causes a clamping action between the core and the external surface of a pipe inserted therein. <IMAGE>
