Patent GB-2028111-A (GB)
Title: Improvements in brush-type vacuum cleaners
IPC: A47L5/32
Filed: 1978-08-15
Abstract: A vacuum cleaner has a housing, containing a cylinder brush 12 and a fan 15 which draws air from the brush and delivers it to a dust bag. An opening 27 is provided in the housing to which a flexible suction hose can be connected, air then being drawn along the hose and into the dust bag, rather than from the brush. A nozzle 28 of the suction hose is arranged upon insertion through the opening into the housing to divert the air flow as required, to pass from the hose to the bag, and also causes a support to be projected through a bottom opening of the cleaner so that the front part of the cleaner, and the brush, is lifted clear of the floor. When the cleaner is to be used without a suction hose, a plug is inserted through the opening in the housing. The plug leads the air flow from the brush to the dust bag and locks the support within the housing so that the brush is in contact with the ground. <IMAGE>

Patent GB-2042650-A (GB)
Title: Gear Box with Lubricant Evacuation System
IPC: F16N31/00
Filed: 1979-11-23
Abstract: A gear housing encloses a gear train and contains an integral oil reservoir 70 which keeps the quiescent oil level above the bottom gears 30 and 32 in the train and includes a passageway 62 with a bottom opening enshrouding the gear 32 at the bottom of the housing. Rotation of the bottom gear above a certain tooth tip velocity causes viscously dragged oil to be directed by a lip 64 on the passageway into the passageway and vertically upward to an opening 68 which allows the oil to drop into a dammed reservoir 76 from which part feeds back to the gear train while the majority of the oil returns over the dam 78 to the reservoir. Thus, when excessive oil is evacuated from the gear train, the oil will cascade over the dam to the reservoir so as to provide a predetermined maximum volume of oil gravity-fed back to the gear train. <IMAGE>

Title: Poster display device
IPC: A47G1/06
Filed: 1980-03-05
Abstract: The device comprises a box frame of four extruded lengths 10 with a translucent backing panel 14 across the front of the frame and a transparent front panel 18 sandwiching a poster 16 against the backing panel, the front panel being normally held in this condition by a peripheral moulding 20. To change the poster, the moulding is hinged about hinges 28 away from the frame 10, the front panel 18 being retained to the moulding by clips 40 slidable in a channel 36. The panel 18 is held firm in the clips 40 by a resilient sealing strip 48. The backing panel 14 is similarly retained to the frame 10 by further clips 40, which are also used to hold the poster 16. This facilitates changing the poster and obviates the necessity to use adhesive tape to hold the poster. <IMAGE>
Patent GB-2049712-A (GB)
Title: Method of Preparing Resin
IPC: C08F236/00
Filed: 1980-04-29
Abstract: Method of preparing a resin by free radical polymerizing a mixture of hard segment hydrophobic enhancing monomer, optional soft segment hydrophobic enhancing monomer and hydrophilic enhancing organic acid where said method is characterized by the steps of (1) charging a reactor with water and a portion of the initiator and (2) slowly substantially simultaneously adding thereto said monomers and the remainder of the initiator. The important feature of the invention relies upon a relative excess of the initiator in a combination with an elevated temperature (75-95 DEG C) in order to enable the polymerization system substantially free of added emulsifier to be used. The advantage of the invention is the preparation of a particulate resin without the usual attendant, residual coating of emulsifier thereon.
Patent GB-2054662-A (GB)
Title: Colouration process
IPC: D06P3/82
Filed: 1980-04-30
Abstract: A process for the colouration of cellulose or wool textile materials comprises applying a dyestuff containing one or more s-triazinyl groups bearing a quaternary nitrogen substituent, or the precursors of such a dyestuff, in the absence of an acid- binding agent and heating the treated textile material to 150 DEG C or higher to fix the dyestuff to the cellulose or wool. Improved colouration is often achieved by applying urea or dicyandiamide with the dyestuff. The process is particularly valuable for the colouration of cellulose in polyester/cellulose unions when a disperse dye may be applied simultaneously with less problems than encountered with conventional alkali fixed reactive dyes. <IMAGE>
