Title: Preformed plastic foam ankle and leg support block for orthopaedic patients
Inventor: SPIRES ALWYN DONALD
IPC: A61G7/075
Filed: 1989-08-05
Abstract: An ankle and leg support is composed of a single block of plastic foam 1 with a density such that, the weight of a human leg when resting in the shaped slots 2, it will not compress to more than a prescribed linear dimension thus keeping the heels above the surface of the mattress. The foam will be manufactured with a texture that, in its own right, is compatible with and will not chafe the human skin. The block will be of sufficient width and height to give it stability when inhabited by sometimes restless patients. An offset foam block support for a shorter left or right leg as shown in Figs 3 and 4 is made to adjustable dimensions. <IMAGE>

Title: Control of a cooling fan for a motor vehicle
Inventor: NAITOH TAKAO
IPC: F01P7/08
Filed: 1990-07-26
Abstract: A motor vehicle radiator cooling fan control system operates the fan (via relay RY1) whenever the temperature of the coolant exceeds a first reference temperature. The control system detects when a passenger compartment heater 17c is operated and under suitable conditions of a) coolant temperature 31, b) ambient temperature 30 and c) if the vehicle air- conditioning system is not in operation 23, substitutes a second, higher, reference temperature for the first. This reduces on/off cycling of the fan and consequent noise. The level of the second reference depends on the power supplied to the heater blower 45a and can be provided from a look-up table MP. The system forms pan of an air conditioning system with a further air conditioning fan and heat exchanger. There is a complex subsidiary relationship between vehicle speed, operation of the air-conditioning compressor and refrigerant pressure and operation of the two fans in relation to coolant temperature. <IMAGE>

Title: Painting/writing instrument
Inventor: UCHIDA MASAKI
IPC: B05C17/00
Filed: 1990-10-17
Abstract: A front shaft (7) having a brush tuft (5) is axially movable towards a cartridge (4) in order to displace a plug (3) from a discharge port (2) so that ink or a similar liquid may flow from an ink reservoir (1) to the brush tuft (5).

Title: Channel sampling system
Inventor: DUFFIELD DAVID JAY
IPC: H04N5/45
Filed: 1991-06-27
Abstract: An automatic channel sampler system, including a television signal tuner, displays an array of inset pictures on a display screen each time the receiver is turned on. Each inset picture is a still video picture (i.e, freeze-frame) selected by tuning each of the channels in a scan list of channels. Automatic channel sampling is initiated in response to the development of operating power, and is performed while the picture tube is dark during the time in which the picture tube is warming up. A separate user-enterable scan list may be provided for either the automatic channel sampling function, a manually initiated channel sampling function, or both. The separate scan list may be programmed to contain only those channels which the viewer regularly watches, and would have the triple advantages of excluding the sampling of channels carrying programming which is not of interest to the viewer, presenting the sampled images in whatever order is desired by the user, and shortening the time necessary to complete the channel sampling function by eliminating the sampling of the undersired channels. <IMAGE>
