Title: Improvements in alternating pressure beds
IPC: A61G7/057
Filed: 1981-08-27
Abstract: An alternating pressure bed is composed of an envelope in which are formed pockets extending right across the working surface of the bed. A separate inflatable liner is a snug fit in each pocket and can be individually replaced at will. Alternate liners are cyclically inflated in opposite phase by link pipes, each of which is rendered captive across the mouth of the intervening pocket by being threaded through either a non-inflatable lug constituting an extension of the blank end of each liner, or a duct formed along the margin of the envelope itself. The link pipes thus perform the dual function of inflating the liners and of tethering them to the envelope against migration from the pockets. The boundaries of the pockets and of the liners may be sinuous to increase the captivity of the liners and to reduce "bottoming" during use of the bed. Selected linears have an insert layer of a highly heat-absorbent substance held snugly against the top wall. Such liners can be substituted for ordinary linears to support parts of a patient's body such as heels, hips, shoulders, etc. which are particularly susceptible to the development of bed sores in order to lower skin temperature at those parts. <IMAGE>

Title: Liquid crystal displays
Inventor: MOSLEY ALAN
IPC: G02F1/1337
Filed: 1983-04-22
Abstract: The surfaces of glass plates 10, 12 on the inside of a dye phase change liquid crystal display cell are coated with cured-on layers of polyamide 16 and 20. The polyamide layers align liquid crystal molecules with their long axes substantially tilted to the surfaces, but in no preferred direction. This produces cells which do not show patches due to variations in the thickness of the cell, as in homogeneously aligned cells. The polyamide layer, applied by spinning, dipping, spraying or painting, is cured and thus very firmly attached to the glass surfaces resulting in a stable surface alignment condition. A layer of an inorganic oxide or an organosilane may be applied to the surfaces to improve polyamide adhesion. <IMAGE>

Patent GB-833102-A (GB)
Abstract: 833,102. Fare collecting boxes. UNIVERSAL CONTROLS Inc. Nov. 22, 1957, No. 36441/57. Class 106 (3). A multiple coin fare collecting and registering apparatus comprises an inclined plate 18 having sloping tracks 22, 25 on which coins are initially separated from face-to-face into edgeto-edge relation by frictional contact with the plate and are led to a slot 27 between the track 25 and the plate for delivery to the inlet 30 of a rotary transfer device 31 which is intermittently turned to bring the coins into engagement with a downwardly-pressed coin gauging and registering device 34, whence the coins pass to a coin collector or separator. A spring- loaded abutment 35 and a spring-loaded agitator lever 40 form the sides of the inlet 30 and, above the track 25, the lever 40 has a sloping lug 43 for thrusting coins back along the track 25 and towards the plate 18. As the rotor 30 turns to bring each coin into engagement with the gauging device, the lever 40 moves to the right to permit further downward movement of coins in the inlet and is then returned to the left by a rod 48 to break up any jamming. The action of the lever will thrust any bridged coins back against the abutment 35 and raise it from its stop 39 so that the coins are pushed back to the top of the inlet; at the same time, an extension 28 of the abutment will separate bridged coins on the track 25. The lever 40 may be operated manually. The track 22 and a panel 54 behind the track 25 are linked together and can be withdrawn to scavenge the apparatus by means of a manually-actuated cam 76. A front plate 12 and cover 17 are preferably transparent so that the device can be illuminated by a lamp 21 behind a transparent spacer 20. The coin inlet 14 is of sufficient size to receive at the same time all of the coins constituting the fare and has a restricted outlet 15 for preventing the passage of too-large coins.

Title: Method and apparatus for burning fuel
Inventor: MOORE COLIN
IPC: F23D11/22
Filed: 1984-05-29
Abstract: A liquid fuel medium, typically comprising pulverised coal in suspension in a liquid carrier such as a fuel oil or water is supplied by a pump 10 to burner 2. During operation of the burner, a combustible fluid such as propane is added by an injector 20 to a stream of the liquid fuel medium passing to the burner 2. The propane dissolves in the fuel oil. The liquid fuel medium issues from the burner and the dissolved propane flashes off preferentially, causing atomisation of the liquid and thus facilitates combustion of the fluid. To start the burner up, the propane is supplied alone, a stable flame created, and then liquid fuel medium is fed to the burner. The rate of feeding liquid fuel medium to the burner is increased to a maximum and the rate of supply of propane reduced to a minimum, e.g. merely that required for the purposes of atomisation. Oxygen, or an oxygen containing gas is supplied to the burner from a source 30. <IMAGE>
