Title: Trisazo dyestuffs and their preparation
IPC: C09B35/46
Filed: 1958-01-28
Abstract: 2:4-Diamino-1-methyl-benzene-5-sulphonic-acid, used as a component in the preparation of azo dyestuffs (see Group IV(c)) is prepared by heating m-toluylene diamine with oleum at 120-130 DEG C.ALSO:The invention comprises the trisazo dyes of formula:  <FORM:0854957/IV (c)/1> wherein R is a benzene residue and Y is a halogen atom or a methyl, methoxy or sulphonic acid group.

Abstract: 588,580. Buildings constructed of pre-formed slabs. HOOD, A. Feb. 5, 1945, Nos. 2793 and 25982. [Classes 20 (iii), 20 (iv) and 87 (i)] In a wall formed of rectangular channel slabs 11, 12 having flanges 15, 16 at the vertical edges of one face, and arranged in double thickness with their hollow faces opposed, the slabs are of wall or storeyheight and are held together by channel members 22, 28 engaging their bottom and top edges. As shown, the slabs which may be formed of a cement-bound aggregate with reinforcements 17 and capable of being sawn, are provided with cross webs 18 near the ends and intermediately if desired. Edge recesses 19 form dovetail grooves 20 when the slabs are assembled for the reception of railing strips or cement or plaster. The lower channel members 22 are moulded on the concrete raft 21 on which the house is built. Asbestos or other impervious sheeting 26 is interposed between the slabs, and, in order that relative movement of the slabs shall not shear it at the vertical joints between pairs of slabs the vertical flanges may be formed as shown in Fig. 6, or may be inset from the edges of the slabs, in order to provide spaces 93 permitting bending of the sheet. At window openings lintel members 33, 34 are made from extensions of the slabs, and are embraced by the channel member 28. The cill 31 is of channel form to engage the tops of the slabs below it, metal clips 36 engage the recesses. 19 in the slabs and lintel members and hold them together. Internal walls may be formed of a single thickness of the slabs with their hollow sides covered by plaster board. Floors may be formed of lengths 40 of the slabs carried on suitable bearers. The roof consists of the slabs carried by beams 50, 56 formed also of the slabs. An inverted channel member 57 forms the gutter. The staircase (not shown) comprises pre-cast concrete treads with wooden or other surfacing members carried on bearers formed by inverted channel members.

Abstract: 695,228. Windows. BEATON & SON, Ltd., G., and YOUNG, F. C. Feb. 6, 1952 [Feb. 6, 1951], No. 2898/51. Class 20(iii) A vehicle window comprises a hinged window panel 12, Fig. 1, and a sliding window panel 13, mounted in the same pan 10, and slidable when open to overlap the hinged panel the mechanism for controlling the movement of the hinged panel 12 being substantially contained within the thickness of the panel 12 when the latter is shut to enable the panels 12, 13 to be mounted in places closely adjacent to each other. The window, for a vehicle travelling in the direction of arrow X, has a fixed transparent panel 11 above which panel 13 slides between channel 29, Fig. 4, and rail 28, the latter being contacted by spring-pressed grooved shoes 27. The panel 13 may be removed by releasing the block 20 carrying a buffer 32, sliding the panel to the right for one shoe 27 to pass beyond the rail 28 and the other shoe to reach a central gap therein (not shown) and moving the lower end of the panel 13 transversely to the rail 28. The panel 12 which is hinged at 18, has the two side members of its frame provided with spring pressed plungers 21 whose upper ends have pivoted thereto at 19 the longer limbs of a pair of L-shaped links 14, the shorter limbs being pivoted at 15 to lugs 16 on the pan 10. When in the closed position, the longer limbs of links 14 and the ends of the shorter limbs thereof are accommodated in slots 17 in the frame of the panels. On opening panel 12, by finger grip 23, pivots 19 move over centre with respect to pivots 15, the springs 22 urging the panel to the fully open position which is determined by a flange 25 on a triangular stop plate 24 fixed to panel 12 contacting a buffer mounted in the pan 10. At the forward end of panel 13 the pan 10 may be provided with a small outwardly projecting baffle and a narrow canopy may extend along the top edge of pan 10.

Title: Improvements in or relating to electric signalling or indicating means
IPC: G01N7/12
Filed: 1934-01-29
Abstract: <PICT:0426981/III/1> The invention relates to apparatus for detecting inflammable gases, of the kind in which combustion of the gas upon an incandescent filament in a porous vessel produces a partial vacuum which operates a switch to light a warning lamp. According to the invention the switch also energizes a relay which then maintains the lamp alight independently of the detecting device.  The Figure is a circuit diagram of one embodiment of the invention.  The warning lamp 6 is in series with a lamp 5 of smaller capacity which normally glows while lamp 6 passes current without becoming incandescent.  The collapse of the diaphragm 24 which communicates with the porous vessel closes contacts 22, 23 short-circuiting lamp 5 and causing lamp 6 to glow and also energizing relay 29 closing switch 30.  The warning lamp is thus maintained slight until the relay circuit is broken by manually-operated switch 34.

Title: Improvements in the manufacture of ammonium sulphate
IPC: C01C1/242
Filed: 1921-01-24
Abstract: Pyridine is recovered in known manner from the gases leaving an ammonium sulphate saturator in which the absorption of ammonia is continued until a neutral or alkaline reaction is reached.ALSO:Neutral ammonium sulphate is obtained by passing ammonia from the "free" ammonia still into one saturator, which is maintained acid, and the ammonia from the "fixed" ammonia still into a second saturator which is worked so that a neutral or alkaline reaction is obtained.  Acid crystals from the first saturator, after treatment in a centrifugal to remove mother liquor, are transferred to the second saturator in which complete neutralization is effected.  The crystals from the second saturator are treated in a second centrifugal, so as to avoid the action of both acid and alkaline liquids on the same centrifugal. The pyridine is contained in the gases leaving the second saturator, and is recovered in known manner.

Abstract: 1444464 Clothes driers BACON BRO ENTERPRISE CO Ltd 23 Jan 1974 03190/74 Heading A4U [Also in Division G3] A clothes-drying apparatus comprises a horizontal member, adapted to be mounted at one end to a wall, on which is mounted a number of clotheshanging hooks which are extended, or retracted, by a belt driven by a motor responsive to a signal from a sensor. As shown, Fig. 1, a hollow profiled pole 1 partially encloses an endless belt or rope 9, which is driven by an A.C. motor 82, through a pulley 8, and is tensioned by an adjuster 3-7. Clotheshanging hooks 10, inter-connected by a chain 12, are each supported by a transverse roller 11 arranged within the pole 1. The leading hook 10a is attached to the belt and the trailing hook 10b actuates micro-switches 20', 20 through a linkage 14 and a switch bar 15. The pole is supported by a wire 29 and is hung from a wall bracket 21. The micro-switches determine the travel limits of the belt 9 and the direction of rotation of the motor 82 is determined by a control system 23 responsive to a sensor 27. The sensor 27 Fig. 3 comprises a printed circuit board having conductive areas 271, 272 separated by an insulating path 273. The presence of raindrops on the path reduces the insulation whereby a relay is actuated, through a transistor circuit of the control system 23, to energize the motor to bring the clothes under the eaves. The sensor is inclined to shed water and is heated to dry the sensor when the rain stops and thereby condition the control system to energize the motor in the direction for bringing the clothes out from under the eaves.
