Inventor: GEDDES WILLIAM HUNTER
IPC: B41B27/10
Filed: 1966-07-29
Abstract: 1,196,402. Type - justifying apparatus. MUIRHEAD & CO. Ltd. 24 July, 1967 [29 July, 1966], No. 34185/66. Heading B6W. Apparatus for composing a record of justified lines of text from unjustified text information includes: a line-width counter which aggregates character width information during composition of a line; a first circuit which responds to the reception of a discretionary hyphen signal by adding to the counter a width value significant of the hyphen; and, a second circuit which subtracts the width value from the counter in response to the reception of a preferable lineterminating position coming after the discretionary hyphen in the same line while it is still justifiable to the justified line length. The first circuit may trigger a character width calculator to provide a pulse train significant of the discretionary hyphen width value which is fed to a counter and the second circuit responds to the reception of an inter-word space or non- discretionary hyphen (preferable line terminating positions) by temporarily reversing the connections to the line width counter so that incoming width information is subtracted from its stored total to remove the width of the discretionary hyphen.

Title: Improvements relating to columns or posts for gas lamps
IPC: F21S13/10
Filed: 1932-12-03
Abstract: 408,058. Lampposts. STEW ARTS & LLOYDS, Ltd., 41, Oswald Street, Glasgow, and McMINN, E., 126, Kippen Street, Airdrie, Lanarkshire. Dec. 3, 1932, No. 34269. [Class 20 (i).] The standard of a gas lamp for street lighting and the like is made as a gas-tight receptacle and is adapted to form the conduit for the gas to the lamp or lamps. In one construction, the standard 1, Figs. 1 and 2, is closed at its base by a plate 2 welded thereto and gas from the mains 6 is led thereto by a pipe 5. The standard or pole is supported on a base-plate 7 and is firmly secured to the ground by concrete. The upper end of the pole is screwed to receive a coupling 11 which is screwed also to a swan-neck tube 12 carrying the lamp 14. In modifications, the swan-neck tube is replaced by a straight vertical tube which is closed at its upper end and is screwed to receive horizontal branches carrying the lamps. In another modification, the upper end of a lamp-post 27, Figs. 7 and 8, is closed by a plug 31 which is drilled and tapped to receive a pipe 32 connected to the lamp 30. The housing 29 of the lamp rests on a shoulder 28 formed on the upper end of the post. Modified forms of connections between the lamp and the post are also described. In a further arrangement, the gastight receptacle 48, Fig. 15, is adapted to form an extension of an existing standard or pole through which the gas is led by the usual internal pipe 53. The extension is fitted to the existing pole by grub screws 49, and its lower end is closed by a plate 51 welded thereto, the plate being drilled and tapped for connection with the pipe 53.

Abstract: 897,550. Screwing-up nuts &c. HI-SHEAR RIVET TOOL CO. Oct. 9, 1959 [Oct. 20, 1958], No. 34367/59. Class 83 (3). [Also in Group XXV] A tool for driving nuts and the like comprises a spindle 18, Fig. 1, rotatable in a body 11 by a motor 40 via gearing 33, 28, 27, Fig. 2, and having a non-circular, e.g. hexagonal, section bore 70. Nuts 75 loaded in a tube 71 are pressed by a piston 73, subjected to fluid pressure, e.g. compressed-air, to that end of spindle 18 surrounded by a slidable sleeve 54. One or more balls 63 movable in radial bores 58 in the spindle-wall under the control of a groove 57 in the sleeve, hold the leading nut. In use, as the leading nut is applied to a relatively fixed stud &c., the sleeve is moved against a spring 69 until the balls free the nut which is then driven fully home and the hexagonal part shears-off at neck 76. When the tool is removed, the hexagonal part falls away and the balls protrude to hold the next nut. The nose part 55 of sleeve 54 is of nylon or similar material. Tube 71 engages a plug 43 screwed into the body and provided with notches 49 for spring fingers 50 which slow-down the rotational speed of that nut about to enter bore 70 to enable it to become aligned with the bore. The end face of the spindle adjacent the finger 50 may have chamfers 100, Fig. 7, to aid in the alignment.

Abstract: 1,009,392. Bottle-washing machines. BOWATER Ltd. Sept. 10, 1963 [Sept. 13, 1962], No. 34939/62. Heading B8T. In a bottle or like washing machine a plurality of separate bottle receiving units 49 are arranged, five to a carrier 48, over the parallel stationary slideways 12, the feed slideway and the return slideway, the units being moved pneumatically or hydraulically along the slideways. Below the slideways at spaced intervals are transverse rows of jets 47 which are located in line with the necks of the bottles and which serve to supply washing and rinsing liquid to the bottles. At the entrance end of the feed slideway (bottom right of Fig. 1b) an empty carrier is pushed into the empty space by a ram of a pneumatic cylinder and is loaded with bottles. This carrier is then pushed hard against a microswitch to set in motion a cycle of operations which consists of moving all the units on the return slideway by a ram of a cylinder 23 thereby making room at the far end of that slideway for a carrier to be transferred thereto from the feed slideway by a ram of a cylinder. The ram of cylinder 14 then pushes all the carriers on the feed slideway along to locate a further carrier in position for transfer to the return slideway and to leave an empty space at the entrance end. Adjacent the end of the return slideway (upper right, Fig. 16) is a tiltable platform on to which the end carrier has been pushed. This platform is moved to a vertical position by a ram and the bottles deposited on an angularly downwardly disposed bottle receiving table 35 pivoted about its edge remote from the return slideway. This table is also moved to a vertical position by a ram and the washed bottles then placed on a conveyer 39. The carrier on the platform is then pushed to the entrance of the feed slideway to restart the cycle. Jets may also be located above the slideways.

The system is applicable to tone frequency telegraphy in which case multiplexing can be effected by using closely adjacent frequencies. The correcting means may be incorporated in the amplifier 18 and be of the type described in Specification 344,869. To increase the selectivity capacitative effects of the piezo-electric crystal may be neutralized as described in Specification 337,049, [Class 40 (v), Wireless signalling &c.], Specification 261,041, [Class 40 (v), Wireless signalling &c.], is also referred to.

Block copolymers are obtained by polymerizing at least two different monomers in order of increasing acidity in at least two stages of a sequential polymerization process employing an anionic initiator which is the metallization product of a compound having two or more different metallizable functional groups of different basicities. Thus the process proceeds as a block copolymerization by appropriate choice of monomers so that the sites of varying activity in the initiator are employed in sequence, thus yielding a branched polymer when three or more sites are present. Homopolymer by-product may be removed with a suitable solvent.
