Abstract: 1372058 Marine fenders FIRESTONE BURLEIGH MARINE PNEUMATIC FENDERING CO Ltd 14 Jan 1972 [19 Jan 1971] 2685/71 Heading B7S [Also in Division F2] In a fender comprising a pneumatically tyred wheel 11 mounted for rotation about a vertical axis and guided for movement on impact along a path perpendicular to the axis, movement of the wheel is damped. On impact the tyre 12 is deflected to compress the air inside, and the wheel is 11 pushed along the guideway 22 where the tyre 12 is further deflected by rollers 25. The wheel is attached to a piston of an hydraulic damper 30. In one construction, impact movement of the wheel 1 piston is substantially unchecked, liquid in front of the piston flowing to a reservoir 39 and then to the other side of the piston through a non-return valve (43, Fig. 3, not shown). On rebound movement however the liquid has to flow through a restriction (44, Fig. 3). Impact movement may also be damped. In an alternative construction (not shown) impact movement of the wheel is damped by flow of liquid through a restrictor whose resistance is reduced as the impact movement of the wheel progresses. The rebound movement may also be damped.

Title: Machines for washing floors carpets windows and the like
IPC: A47L11/34
Filed: 1973-01-18
Abstract: 1359972 Machines for washing floors &c. UPO OSAKEYHTIO 18 Jan 1973 [24 Jan 1972] 2701/73 Heading A4F [Also in Division B1] In a machine for washing floors, carpets and windows, foam is continuously fed to and removed from a washing implement 1 which comprises one or more stationary or rotating brushes. The machine comprises two tanks 2, 3, containing washing liquid, and an air fan 5 which is connected thereto by passages provided with valves 8, 21, 11, the fan 5 also being connected to the atmosphere via valves 13, 14. Tank 3 is provided with a filter 19 which prevents passage of foam to the fan inlet. The valves 8, 21, 11, 13, 14 are in the form of apertures in two concentric cylinders, the outer cylinder being rotatable by a lever to three operating positions, in each of which a set of apertures coincide so as to open the corresponding passages. Thus in position 1, valves 11, 14 are open and valves 13, 8, 21 closed. Thus on activation of the fan 5, the reduced pressure in tank 3 draws foam from the implement 1 via a removable filter 24. In position 2, valve 8 is open and valve 14 closed, foam being produced in tank 2 by air exiting passage 6 and forced through passage 20 to the implement 1. Should the liquid level in tank 2 fall excessively, an overpressure is produced in tank 3 by opening valves 21, 13 and closing valves 8, 11, 14, thereby forcing liquid from tank 3 to tank 2, this being position 3 of the lever.

Title: Improvements in and connected with vee gauges
IPC: G01B3/34
Filed: 1933-01-30
Abstract: 394,909. Linear-dimension gauges. HOUNSFIELD, L. H., 3, Durrington Park Road, Wimbledon, London. Jan. 30, 1933, No. 2825. [Class 106 (ii).] A V-gauge comprises two operative edges 3, 4 of blades 1, 2, inclined at an angle, a hinge 5 where the edges if produced would meet, a third member 6 connecting the non-meeting ends of the blades in such a manner that the inclination of the blades can be varied and means 7 for locking the blades in this position. The yoke 6 is riveted to the blade 1 the blade 2 moving within the yoke until locked by tightening the screw 7. The blade 1 is graduated to measure relative areas and the blade 2 to give reduction per cent in area such as is required in measuring the area adjacent to the fracture in a test piece after test. The test-piece is shown at 9, 8 before and at 9, 10 after fracture. Prior to the test the stem is held opposite to zero on the blade 2 and the blades closed on it and locked. The cut-away part 11 enables withdrawal of the piece without disturbing the setting. The edges are chamfered except at the parts at the wide end of the V which are in most use and have a certain width to prevent damage. If the gauge is to be used for comparing the core strength of screws the blades may be chamfered on both sides. For this purpose the unit mark on blade 1 cannot be used, so the gauge is set to the standard bolt, say at " 8." then if a second screw comes to " 6," the core areas or strengths are as 8: 6. ,

Abstract: 1387991 Shelping ribes POST OFFICE 19 April 1972 [22 Jan 1971] 2951/71 Heading B3E [Also in Division H1] Armouring for an electric cable comprises an elongate strip of expanded metal mesh, e.g. steel mesh. One side of the mesh strip is formed with outwardly extending tongues which engage in the apertures of the mesh on the other side of the strip when the strip is folded about a cable. The tongues are then bent backwards and flattened on to the mesh to form a seam extending along the length of the cable. In a second embodiment the mesh strip is formed with margins that are not apertured. When the strip is folded around a cable the margins of the strip are bent at right angles to the mesh immediately adjoining them and are brought face to face. The margins together are then bent through 180 degrees and then through a further 90 degrees, e.g. using mechanical rollers. Mesh strip may be fed from a drum to folding rollers that bend the strip into a "U"-shaped crosssection. The strip is then wrapped on to the cable by wrapping rollers and a further set of rollers complete the wrapping such that tongues on one side engage apertures on the other side of the mesh, the tongues being subsequently bent back by a hardened steel "plough" and flattened by a final pair of rollers.

Abstract: 1291977 Colour separation systems 19 March 1970 [26 March 1969] 3256/70 Heading G2J In a system for separating different wavelengths from a polychromatic light beam # 1 -# 3  the beam enters an open face of an optically hollow space of square cross-section and strikes a diagonal plane beam-splitter 9, two edges of which coincide with edges separating four faces of the space, one of which is the open face, and there being filters on the other three faces, 1, 2, 3, the incoming polychromatic beam # 1 -# 3  is split to give part reflected to one face 2, and part transmitted to face 1, at least one filter on faces 1 or 2 transmits a single desired wavelength and reflects the others. The space is so oriented that the optic axis of the polychromatic beam passing through the beam-splitter strikes a side 1 of the cube normally. The beams reflected from the filters encounter the beam-splitter at least once more. Desirably all the filters on all three sides are reflecting interference filters although only one needs to be reflecting. The other two can be absorption filters. The beam-splitter may be achromatic or dichroic. The initial beam may be either convergent or collimated. The system is used to separate three to six colours inclusive. Where more than three colours are to be separated the incident beam is split into two portions each going to an optically hollow space constructed as above. Where the filters are interference filters retardation plates are located in front of the filters to control polarization effects.

Title: Improvements in ion exchange processes for the treatment of liquids
Inventor: EMMETT JAMES RATCLIFFE
IPC: C13B20/14
Filed: 1950-02-13
Abstract: To ensure the maximum efficiency in the regeneration of the ion-exchange material used in the treatment of a liquid, e.g. water containing both salts of weak acids, e.g. bicarbonates and salts of strong acids, e.g. sulphates by an ion-exchange process operating on the hydrogen cycle, at least two cation exchange materials containing differing proportions of weakly acidic active exchange groupings, e.g. sulphonic are so associated that all the cations of the salts of weak acids will be exchanged for hydrogen ions on the weakly acidic groupings and the cations of the salts of strong acids will be exchanged for hydrogen ions on the strongly acidic groupings. Preferably, at least one cation exchange material contains a preponderance of weakly acid groupings and at least another contains a preponderance of strongly acidic groupings.  At least one of the materials may contain groupings of substantially only one character. The overall ratio between the weakly acid groupings and the strongly acid groupings in the associated exchange materials should preferably be substantially the same as the ratio between the salts of weak acids and the salts of strong acids in the liquid to be treated.  The materials may constitute a common bed or they may be distributed between two beds in a single vessel or in two vessels so as to be traversed in series by the liquid under treatment and so that substantially all the weakly acidic groupings are found in the bed encountered first by the liquid. In this latter case the volumes of the respective materials should preferably be such that the material in one bed will require regeneration in a period of time which is an integral multiple of the period of time at the end of which the material in the other bed will require regeneration.  The Provisional Specification refers to Specification 450,308.
