Title: Water heater
Inventor: ROFFELSEN FRANCISCUS
IPC: F24H1/22
Filed: 1969-12-03
Abstract: 1,235,796. Water heaters. F. ROFFELSEN. 3 Dec., 1969 [16 Dec., 1968], No. 59097/69. Heading F4A. A water heater comprises a smooth inner tube 2, above an oil or gas burner 23, surrounded by an annular water space 1 enclosed within an outer tube 3 and insulating jacket 7, and has radially extending rods 8, made of metal of good thermal conductivity, piercing the inner tube 2. The inner and outer tubes 2, 3 are extended beyond the insulating jacket 7 and surrounded by an outer water space 19 heated through radially extending rods 20. Water in the outer space 19 is used for consumption while that in the inner space 1 is used for central heating. The outlet to the heating system 10, 11 is provided with a pump 14, a valve 13 which may be adjusted manually or automatically to regulate the flow of hot water to the heating system, and a valve 15 acting as a shunt to the return pipe 9 to enable water for consumption to be heated when the heating system is shut off. The outer casing has inlet and outlet pipes 21, 22. Thermostats 25 and 26 control the burner respectively when the heating system is in operation and when only consumption water is required. The rods, which may be of copper and adapted to suit the heat content of gas and water, are arranged around the circumference of the inner tube 2 in rows or following one or several helical paths. Since almost all the heat exchange is through the rods, the tube 2 may be made of poorly conducting material, for example synthetic plastics material if necessary lined or coated on the inside with a heat reflecting or heat blocking layer.

Title: Apparatus for the precision metering of solids
IPC: B65G65/46
Filed: 1971-12-30
Abstract: 1377510 Screw conveyers A ZIMMERMANN [trading as AZO-MASCHINENFABRIK ADOLF ZIMMERMANN] 30 Dec 1971 [7 Jan 1971] 60798/71 Heading B8A [Also in Division G1] Apparatus for the fine dosaging of solids liable to cake, comprises a feed device 10 incorporating a worm 11, freely coupled to a motor 18, which rotates within an elastomeric guide tube 12. Caking within a container 1 is minimized by air pulses from conduit 8 which pass through an airpervious floor 4. The feed device 10 deposits the solid to a container 45 via a dust-tight weighing device comprising a rubber tube 41 longitudinally clamped and closed at its lower end by an elastomeric sleeve 49 expanded by compressed air from a tube 47. The upper end of the sleeve 41 is fastened to a ring 42 attached, via a bowed arm 64, to a spring 62 of a balance. The spring may be preloaded by rotation of a knob 66 which raises a spindle 65 attached to the spring 62, faces 68, 69 then abutting. When this preloading is exceeded by the mass of solid material delivered to the tube 41, the arm 64 moves downwardly to activate a limit switch 72. This stops the motor 18 and opens the rubber tube 41. When continuous dosing is required the weighing device is removed.

Patent GB-2046051-A (GB)
Title: Real time histogram modification system for image processing
IPC: G06F17/18
Filed: 1979-03-29
Abstract: An iterative real time histogram modification system for use in image processing, such as image contrast enhancement of for example scenes, radiograms and thermograms. In the described system input analogue video signals to be modified are digitized and applied to an encoding module including a code RAM which compresses the input grey levels into a lesser number of output grey levels in accordance with a recoding strategy applied to the code RAM. The recoding strategy is determined iteratively using a predetermined scene adaptive operator. This is done by forming a histogram of the pixels in the respective output grey levels. Thereafter the count in each grey level is compared with a predetermined population figure for that grey level and if the difference between the count and population figure is outside an acceptable range, termed a window, then the recoding strategy to be used during the next frame of the input signals is altered so that the number of input grey levels compressed into the particular output grey level is adjusted appropriately. The recoding strategy may be applied to a local area of the frame, which area is selected at will, or to the entire frame in which case the histogram is formed from a subset of all the pixels. The scene adaptive operators include histogram equalization, Gaussian distribution, hyperbolic and exponential. By using a suitably programmed microprocessor different scene adaptive operators may be selected at will and a "zoom" facility may be provided in which the size of the local area is varied and corresponding changes are made to the window and set of population figures.

Title: Control System for Wood Working Machine
IPC: G05B19/414
Filed: 1979-04-12
Abstract: A control system for automatically setting the positions of a plurality of tool holders of a wood working machine in accordance with instructions in a memory M has associated with each tool holder a servo motor SM1-SMn and a position detector S1-Sn selectively connectable by a pair of switches A, B to a central computing and processing apparatus CP. On initiation the central processor places switches A & B in a first position and selects the appropriate desired position from memory M to drive the tool holder until the feedback signals from the position detector indicate that the work tool holder has reached the preset position stored in the memory. Thereupon the central processor changes the switches to a subsequent position and adjusts the position of the next work tool holder and so on until all are positioned correctly. The memory may contain a number of different setting schedules for setting the machine to perform different operations. <IMAGE>

Title: Pipe making apparatus and method
IPC: B28B21/96
Filed: 1979-08-22
Abstract: Roller suspension process and apparatus for manufacture of pipes of concrete or other cementitious material. An open ended tubular pipe mould 13 is suspended on a horizontal suspension roller 16 extending through the mould and the mould is rotated by driving the suspension roller. Cementitious material is fed into the mould as it is rotated so as to be spread evenly around the mould and is compacted by the suspension roller. After compaction of the pipe wall, lower sets of wheels 21 are raised to lift the mould and allow it to rotate at reducing speed. Consequent relief of compaction pressure and peripheral speed differential between support roller and rotating pipe wall causes the support roller to burnish the inner surface of the pipe wall and eliminates slumping of pipe wall when mould comes to rest. <IMAGE>
