Title: Improvements in or relating to feed-back mechanisms for regulators
IPC: F15B9/00
Filed: 1966-03-17
Abstract: 1,65,070. Fluid-pressure servomotor systems. KALLE-REGULATORER A. B. March 17, 1966 [April 20, 1965], No.11774/66. Heading G3P. In a PID controller, a diaphragm 16 responds to pressure signals in a line 19 to rotate a lever 14 to adjust the air intake valve of a pump 7 via stem 9, thereby regulating the output of the pump in line 11 to position a servo-piston 5 connected via stem 6 to a controlled device (not shown) movable against the action of a spring or counterweight. Movement of stem 6 is fed back to the lever 14 via lever 22 pivoted at 23, adjustably positioned link 25, vertical rod 26, bellows 32, bellows 31, rod 35 and leaf spring 36. Bellows 31, 32 are concentrically arranged and the space between them receives oil from the pump 7 via restriction 12, line 40, head tank 27 and manually adjustable valve 39. The base 33 of bellows 32 carries one end of a bellows 43 the other end of which is fixed to plate 42. Bellows 43 communicates via manually adjustable valve 46 with the oil in sump 3. If valves 39, 46 are respectively fully closed and fully opened, the controller has a proportional action only, whereas if valve 39 gives a throttling action the controller has a proportional-plus-integral action. If valve 46 is given a throttling action, some of the feedback force is temporarily stored in spring 48 forming part of rod 26 and the controller has a proportional-plus-integral-plus derivative action. Spring 48 may be replaced by a spring forming a portion of lever 22. In the embodiment of Fig. 1 (not shown), the derivative bellows 43 is omitted, and valve 39 is optionally positioned in base 33.

Title: Improvements in or relating to cold cathode, glow discharge devices
Inventor: DUGDALE RONALD ARTHUR
IPC: H01J37/08
Filed: 1965-03-19
Abstract: 1,145,013. Removing metal by fusion. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 15 March, 1966 [19 March, 1965], No. 11897/65. Heading B3V. [Also in Division H1] An electron beam 33, derived from cathode 22 and a glow discharge within anode 6, is used to micromachine a body 27 which may be of metal, semi-conductor or ceramic or a combination thereof to form an electronic microcircuit. After passing through a baffle 35, which reduces contamination of the beam generator by vapour from the body 27, the beam passes through two pairs of electromagnetic deflecting coils 36 and is then focused by a further electromagnetic coil 37 on to the body. To effect the required removal of material from body 27 the intensity of the electron beam is varied using the control electrode 23, and the deflecting coils 36 cause the beam to trace out the required path on the body. These controls may be effected automatically by a programme, and orientation of the body or its replacement may be similarly controlled. In another form, Fig. 12 (not shown), a conical beam of greater intensity is formed for the melting or machining of comparatively large bodies of refractory material, e.g. ceramic. The electron beam generator, which may also be modified to produce an ion beam, may also be used in type setting by machining from a block, shaping optical lenses, electron beam welding, and any application where intense but controlled heating is required, e.g. annealing, melting, evaporating, refining, crystal growing.

Abstract: 1,147,531. Recording on tape by laser beam. ROBERT BOSCH G.m.b.H. 18 March, 1966 [20 March, 1965], No. 11912/66. Heading G5R. [Also in Divisions H1 and H4] In a method of recording items of information a thin surface layer supported by a recording carrier is permanently structurally altered by a laser beam or beams incident thereon which beam is modulated in relation to the information to be recorded. The thin surface layer may comprise vapour-deposited metal or a layer of insulating material. As shown, a recording medium A consists of transparent plastics film T carrying a vacuum-deposited cadmium or zinc metal layer O which is melted or vaporized at the focal point B of light beams transmitted from a laser L. A Kerr cell K controls the intensity of light in dependence upon the brightness of the image point to be recorded, as measured by a photo electric cell P. A rotary mirror S deflects light beams on to the recording medium A which may be movable. Alternatively the laser beam may be conducted through a double refracting crystal, the index of refraction of which is varied by employing an electrical or magnetic field. The recording medium may be used to record television pictures or the results of electronic calculating machines.
