Title: Improvements relating to pneumatic material handling apparatus
Inventor: TRYTHALL WILLIAM JOHN COURTNEY
IPC: B65G53/36
Filed: 1983-10-18
Abstract: An apparatus for conveying bulk powders or other granular materials through pipe systems employs a generally cylindrical pressure vessel or blowing tank 44 from which the material is fed as from a hopper via a chute 36 and a valve 32 that can be closed to render the vessel 44 gas tight. Thereafter compressed air is introduced to cause the material to move into the pipeline 43, 47. The vessel 44 is offset from the inlet flange of the apparatus at an angle to the vertical so that the material flows from one side into the top of the vessel and enters via the valve aperture. The inlet valve 32 is not interposed between the hopper 45 and the pressure vessel 44 but is located to one side so that it can be removed easily to permit servicing or to give access to the interior of tie vessel 44. The interior of the vessel is provided with one or more circumferential air distribution rings that give a generally downwards flow of fluidising air that prevents blockages. <IMAGE>

Title: Temperature regulating apparatus for machine tools
Inventor: KIMURA SOSAKU
IPC: B23Q15/18
Filed: 1983-11-01
Abstract: A temperature regulating apparatus for a machine tool, e.g. a vertical grinding machine, intended to reduce variations in the temperature of a fluid to be supplied to the heat generating parts of the machine tool, in order to prevent irregular thermal deformations of the machine elements, particularly, of the precision guideways, or the irregular thermal deformation of the work being machined. The hot fluid recovered from the heat generating parts is cooled to a predetermined temperature by a combined cooling unit- control device, and then the cooled fluid is treated by a temperature regulating tank (28) to make uniform the temperature distribution in the fluid while the fluid flows through the temperature regulating tank along a zigzag path defined by a plurality of plate members disposed therein in a staggered arrangement. Dust and bubbles contained in the fluid are separated by the plate members from the fluid before the fluid is supplied via pump 22 to the heat generating parts. <IMAGE>

Title: Method and apparatus for forming an image of the ocular fundus
Inventor: BILLE JOSEF
IPC: A61B3/12
Filed: 1983-12-08
Abstract: In contrast to techniques currently used such as the fundus camera, the strain to which the patient is exposed during the generation of an image of the ocular fundus is reduced by moving a laser beam across the retina in the form of a scanning raster and by directing the light reflected from the retina through a photoelectric receiver to generate a television image. To achieve a very high resolution, the scanning operation provides at least in the interesting image parts signals which are representative of a greater number of image points than corresponds to the television standard. These image parts are selected sufficiently large to have each point of the raster assigned a separate image signal value when displayed on the television screen. During the time the scanning beam moves within the frame of a selected image part, its intensity is increased for improved image contrast. The apparatus for implementing this image-forming method utilizes at least one polygonal scanner and includes an active image element that cooperates with a sensor to form a closed loop circuit for optical focusing of the image under adaptive control. An electronic shutter is provided to control the intensity of the scanning beam. In addition to the formation of images, the apparatus also permits a measurement to be made of the spatial blood flow distribution in the fundus and of the degree of oxygen saturation of the blood in the retina of the eye under observation.

Title: Control for a heating means
Inventor: PURCELL DAVID STANLEY
IPC: G05D23/275
Filed: 1987-02-13
Abstract: A control for a heating means, particularly a domestic immersion type water heater 10, comprises a thermostatic switch 11 which interrupts a power supply to heater 10 when a predetermined temperature is sensed, and a latched switch R1 which when closed connects power supply 16 to switch 11, the latched switch R1 being maintained closed by a feed back signal 15 derived from supply 16 by a connection 13 between switch 11 and heater 10 so that once switch 11 deactivates the heater, the heater will remain off regardless of the thermostatic switch 11. Heater 10 may be turned on again by momentary closure of a switch 21, or when a timer 40 causes a monostable 41 to generate a turn on pulse, so that a signal passes via a diode D3 to the coil of a relay R1 having normally open contacts between supply 16 and switch 11. Closure of these contacts energises heater 10 and provides the latching signal to the relay coil via leads 15, 26, 28. A manual override switch 22 allows heater 10 to be cycled on and off by switch 11. Overheating causes a thermal fuse 31 to go open circuit resulting in opening of the contacts of relay R1 and energisation of an alarm sounding circuit 32, 34. <IMAGE>
