Title: Calligraphy learning aid
IPC: G09B11/00
Filed: 1981-02-20
Abstract: The main problem encountered by a left-handed child writing from left to right is the lack of visual feedback when executing a line of writing, due to the fact that what has just been written is progressively obscured by the child's left hand as he continues along the line. Continuous visual comparison with anything just written is therefore quite out of the question as the line of writing is executed. An aid for assisting left-handed writers comprises a hollow desk having a sloping top 13 and an aperture 17 through which the interior can be seen. The paerture is covered with transparent material such as glass and one or more tapes 20 are placed across the covering. Inside the desk there is a respective long narrow mirror for each tape 20. Each mirror is angled to face the respective tape and reflects back the image of the underside of the respective tape when viewed through the aperture. The reflection is located above the respective tape. Each tape is of tracing cloth or the like. When a tape is written on, the reverse image of the writing shows through the underside of the tape and that reverse image is reflected by the respective mirror so that a true image of what is written can be seen above the tape. Thus, a left- handed writer will be able to see words which at that time may be covered by his hand or arm. The device is of course similarly useful for right-handed writers writing from right to left. <IMAGE>
Patent GB-2079913-A (GB)
Title: Web drying apparatus
IPC: F26B13/00
Filed: 1981-03-11
Abstract: A secondary supply of hot air prevents the formation of condensate in internal walls near the entry and exit slots for the web. Hot air enters the chamber (2) from a primary supply 6), and is extracted through an exhaust duct (9) or recirculated (10). Secondary air supplies (14), comprising air nozzles above (15) and below (16) the web, direct hot air at high pressure into the chamber to establish a hot air curtain inside the chamber, close to the slots. This prevents condensation caused by the entry of cold air through the slots from outside the chamber. <IMAGE>
Patent GB-2076661-A (GB)
Title: Valves and breathing apparatus incorporating such valves
IPC: A62B9/02
Filed: 1981-05-28
Abstract: A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm (27) coupled to a pivoted beam (17) which lies in the path of a jet of gas which vents from a control chamber (13) through an orifice (16), gas being supplied to and venting from the control chamber continuously throughout use. Deflection of the diaphragm (27) in response to pressure changes in a second chamber (29) caused by inhalation and exhalation of the user of the apparatus pivots the beam (17) towards or away from the jet orifice (16) to control the rate of venting from the control chamber (13) by interaction with the gas jet, and thereby varies the pressure within the control chamber. Flow of gas through the valve to the user of the apparatus is controlled by a flexible disc (9) which in turn responds to the pressure in the control chamber (13). Resilient means e.g. diaphragm (33) separate from the beam (17) biases the beam/diaphragm assembly (17, 27) to a position which corresponds to an open condition of the valve, to provide for "positive pressure" operation of the associated breathing apparatus. In a second embodiment, Fig. 6, (not shown), the resilient means comprise a spring (64). <IMAGE>

Title: Improvements In Solid Fuel Fired Boiler Operations
IPC: F23K3/00
Filed: 1981-10-05
Abstract: Dust and small particles of coal, grits form a significant percentage of the heat value of any solid fuel. It is important to optimise its combustion. High velocity grates and fluidised combustors inflict a high degree of agitation within their firebeds, this tends to dissociate the lighter particles of fuel from the high temperature furnace zone before complete combustion. This invention describes a method of catching, storing and processing this heat potential in such a way as to optimise its combustion without introducing detrimental boiler practices. It involves catching and holding of dust, grits etc in a separation chamber associated with an arrester or filter system until such time as the boiler firebed is dormant, i.e. combustion air supply ceased. The invention then provides a control system which will program a feeding mechanism to remove the grits from the holding chamber and deliver them onto the dormant firebed. <IMAGE>
