Title: Improvements in apparatus for the separation and recovery of gases and vapours by absorbent solids
IPC: B01J8/02
Filed: 1927-07-25
Abstract: 295,504. Godel, A. July 25, 1927. Addition to 267,369. Gases, separating mixtures of.-The apparatus described in the parent Specification is modified so that the container for the absorbent material is provided with a central cylirdrical chamber in which is arranged a beating or cooling device. such as a nest of tubes, and a fan, injector, &c. for the circulation of the gases to be treated. The chamber A is provided with a frusto-conical base a having a grating B supporting absorbing material and through which passes a cylindrical chamber Q. Tubes q, housed in the chamber Q, connect the space above the absorbent with a header N. secured to the base a and having a valve H through which the gases to be treated enter. The cover of the device may be removable or be provided with a manhole G, others being mounted in the side wall if necessary. A pipe N<1>, situated near the outer rim of the base a, gives access, by a four-way union, to the gas exit, to the air exit, and to the fan J by way, respectively, of valves H<1>, V<1>, and S, the fan delivering into the header N. A valve B admits air to the pipe connecting the valve S with the fan J. Heating the tubes q is effected by steam entering a pipe m', which is provided with a valve m and extends upwards through the lower tube plate q<1>, the steam being withdrawn by a pipe n<1> having a valve n and extending downward from the plate q<1>. Cooling is effected by a circulation of water in the reverse direction. In operation, during the absorption phase, the valves S, V, V<1> are closed and the valves H. H<1> are open to allow gas to enter the valve H, pass upwards through the tubes q, downwards through the absorbent, and out at the valve H<1>. Cooling water may be admitted to the chamber Q if necessary. If the gas under treatment contains a large quantity of absorbate, it is diluted with gas already treated by opening the circulating valve S and operating the fan J. - After the absorbent is sufficiently saturated, the apparatus is heated, prior to removing the absorbed material, to induce the effect described in the parent Specification, by beating the tubes by steam &c., opening the valve S and operating the fan J to cause the contained gases to pass round the circuit S, J, N, q, the interior 1, N<1>, S. The absorbed products which are given off pass out through a pipe h to the condenser. Steam may be introduced into the absorbent through a valve t carried by the header N. The circulating valve S may be closed and the fan J stopped, or the steam may be circulated by these means. After the removal of the absorbate, the absorbent is dried by gases already treated, or by means of air. In a modification. the space between chambers Q, A is divided by one or more concentric chambers containing tubes similar to the tubes q and provided with similar heating and cooling means, or the chamber A may be divided into compartments connected by nests of tubes.

Title: Combined Stocking and Pad for Amputated Legs.
Inventor: BLEVENS EMMETT
IPC: A61F2/78
Filed: 1919-08-11
Abstract: 136,504. Blevens, E. Aug. 11, 1919. Limbs, artificial. -Comprises means for fitting stumps to the sockets of legs so that the minimum of pressure is borne by the end of the stump during the use of the limb. The construction comprises an arrangement of stockings with an interposed pad fitted so that substantially the whole of the pressure is transmitted from the periphery of the stump to the casing or walls of the artificial leg. An inner stocking or bag 12 of knitted, woven, or like material fits closely round the stump. An outer stocking 11 is attached to the inner stocking intermediate to its ends, and a pad' 14 is inserted between the two stockings. The upper portion of both stockings fits closely round the thigh. The pad, preferably of sponge rubber, is formed with bevelled edges. The edges 15, 16 may overlap when the pad is in position, thus enabling the pad to be adjusted to legs varying slightly in size. Various standard sizes of pads are made so that the above-mentioned adjustment can be minimized by a suitable selection of pad. The bevelled surfaces at the top and bottom of the pad prevents ridges appearing in the stockings when the pads are in position. The pads are sloped away at 19, 20 when they pass round the sides of the leg to the back of the knee. Where a stump has shrunk, a series of superposed outer stockings may be used, between any two of which the pad may be fitted.

Title: Improvements relating to radar equipment
Inventor: MCQUEEN JACK GORDON
IPC: G01S7/292
Filed: 1965-05-11
Abstract: 1,086,884. Radar; interference reduction. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 11, 1966 [May 11, 1965], No. 19849/65. Headings H4D and H4L. The invention relates to a pulse radar receiver incorporating means reducing interference from signals at the radar frequency and of long duration e.g. ground clutter. An interference signal of the I.F. frequency f1 is fed via a wide band amplifier to a power limiter, which limits the total power content of the received signals within the pass band of the wide band amplifier. The output of the power limiter is fed to a narrow band amplifier, having a band width just wide enough to accept normal echo signals. After detection, the output of the narrow band amplifier is fed to the display means. Part of the output is also integrated, and for a long duration interference signal, builds up a resultant integrated signal at the control input of an amplitude modulator. The modulator modulates a C.W. signal of frequency # 2 , within the pass band of the wide band amplifier, but outside the pass band of the narrow band amplifier, such that the modulated C.W. signal is applied to the power limiter, and, for said long duration interference signals, is of such amplitude as to saturate the limiter and reduce the output of the limiter at # 1 . The amplitude of the interference is accordingly reduced.

Title: Electric line and fluid conduit assembly
IPC: B66F9/20
Filed: 1975-05-12
Abstract: 1498260 Electrical connectors CLARK EQUIPMENT CO 12 May 1975 [3 July 1974] 19936/75 Heading H2E In an electric line and fluid conduit assembly, one or more electric lines 28 which pass into a fluid conduit 10 via a coupling unit 20, and which each comprise a conductor with insulation therearound, are provided with means permitting fluid in the conduit 10 to flow into the interior of the insulation so as to contact the conductor of the or each line. There is further provided means which fluid tightly secures the one or more lines 38 in the coupling unit 20. As described, fluid tightness is effected by an elongate grommet 30 secured within the unit 20, which may be a T, Y or other shape by means of a metal plug 32 and a nut 34. Metal support tubes 50 support the electric lines so that fluid turbulence within the unit 20 will not damage the line(s) 28. Each electric line 28 preferably comprises a solid wire 62 and a multiple wire 64 coupled by a conducting tube 54 by crimping as at 66. The fluid is allowed access to wire 64, for lubrication, cooling and/or pressure equalization, by terminating the insulation thereof at the end of the tube (as shown) or by providing slits or perforations in the insulation 28 of wire 64. The solid single wire 62 ensures no fluid leakage. The tube(s) 54 may be situated within the conduit 10 as shown or may take the place of the support tubes 50 and be situated within grommet 30 (Figs. 3 and 4, not shown). Alternatively tube(s) 54 may be omitted, a continuous multiple wire conductor being employed. Sealing, e.g. by stripping and soldering, at each coupling unit 20 is then necessary. The conduits 10 are disclosed as being used in a masted fork lift truck (Figs. 7 and 8, not shown), wherein to compensate for the changes in the length of the conduit 10 resulting from fluid pressure changes, the electric line(s) 28 are arranged in a serpentine or helically coiled manner within the conduit 10 (Fig. 6, not shown).

Title: Feed mechanism for presses
IPC: B21D43/04
Filed: 1958-06-23
Abstract: 861,186. Feeding blanks to presses. DYCHE, L. June 18, 1959 [June 23, 1958], No. 19989/58. Class 87(2). [Also in Group XXII] Mechanism for feeding blanks to a press comprises a platform 21, a feed member 13 disposed above the platform and having formed in it an aperture or recess to accommodate at least part of a blank resting on the platform, means operable in synchronism with the press to move the feed member between a loading position in which the aperture or recess is above the platform and a position in which the aperture or recess is above the press die 20, and to cause the feed member to dwell and then to lift, while in the latter position. A guide 11 is pivotally attached, at one end to lugs 10a on the body 10 of the press. The feed member 13 is attached to a slide 12 by an arrangement of bolts 16 and slotted brackets which enables it to be adjusted in three dimensions relatively to the slide. In the loading position, Fig. 1, the aperture in the feed member 13 is beneath a magazine containing a stack of blanks 14 of which the lowermost rests on the platform 21. When a shaft 24 is rotated, through a link 26 from the crankshaft of the press, an actuating arm 28, through a link 29, advances the slide 12 along the guide 11 to the delivery positions, Fig. 2. The arm 28 is rotated by the shaft 24 through an overload clutch 30, Fig. 5, so that when, at the end of its travel, it is arrested by an adjustable stop 35 the feed member 13 dwells with the blank above the fixed die 20 of the press. One arm 27a of a bellcrank, also rotatable with the shaft 24, then makes contact with an adjustable stop 32 at one end of a plunger 13 and advances the plunger, causing a cam surface 31a on the plunger to raise a vertical push rod 34 which in turn tilts the guide 1 upwards about its pivot resulting in the feed member 13 rising clear of the blank 14 on the die, as shown in Fig. 2. The press then rotates the shaft 24 in the opposite direction, causing retraction of the slide and feed member. Back at the loading position, the other arm 27 of the bellcrank makes contact with an abutment plate 33 on the end of the plunger 31 which is thus retracted also, moving the cam surface 31a from beneath the plunger 34 so that the guide 11 drops back to the horizontal. This movement is made positive by the engagement of a roller 40 with the underside of a head 31b on the plunger 31, the roller 40 being mounted on a stirrup 39 depending from the guide 11. To prevent the blank from jumping out of the aperture in the feed member 13 as it is advanced towards the die, a pivoted arm 41, Fig. 6, is caused, by a spring 42, to bear on the blank, this arm being swung clear, as the feed member moves to the loading position, by meeting a brigde piece 19 which forms part of the magazine. Rollers are positioned to steady the guide and to locate the feed member accurately.
