Title: Improvements in Surface Measuring Apparatus
Inventor: REASON RICHARD EDMUND
IPC: G06K11/02
Filed: 1967-12-18
Abstract: 1, 195,240. Optical gauging apparatus. Measuring roughness photo-electrically. RANK ORGANISATION Ltd. Dec. 18, 1968 [Dec. 18, 1967], No. 57387/67. Headings G1A and G1M. [Also in Division G2] Apparatus for measuring the roughness of the surface 6A of a workpiece 6 comprises a source 24 for producing a light beam 28 from which a reference beam 46 is directed along and spaced from the surface, a sensor 22 having a stylus 50 engageable with the surface and traversing the surface along a line parallel to the path of the beam, a beam displacing prism 48 coupled to the stylus and deviating the reference beam to form a measuring beam and detection means for indicating any displacement between the reference and the measuring beams thus providing an indication of the surface profile. The source 24 may include an incandescent filament lamp or a laser and the beam 28 is reflected from a prism 34 in a hollow part 30 of the base 2 on to a prism 38 attached to a movable platform 16. The platform 16 is slidable in a guideway 12 in a hollow pillar 8, the beam from the prism 38 passing through a slot 14 and being deflected from prisms 42, 44 to emerge as the reference beam 46. The prism 48 deviates the reference beam by 180 degrees to form the measuring beam, the position of which changes with respect to the reference beam as the stylus undergoes vertical movement due to the roughness of the surface 6A. The sensor 22 is mounted on a carriage 20 connected by a hinge 21 to a rod 18 which is horizontally movable to enable the stylus to traverse the surface 6A. The vertical movement of the platform 16 and the horizontal movement of the rod 18 may be effected manually or by a motor driven lead screw and gear assembly. The displacement of the measuring beam is twice the vertical displacement of the stylus and the detection means for measuring the displacement are shown in Fig. 4 in which a light transmitting plate 62 with an opaque reflecting strip 64 replaces a reflective strip 44A shown in Fig. 1. In an equilibrium position of the sensor the reference and measuring beams are coincident but movement of the sensor displaces the measuring beam beyond the sides of the strip 64, the displaced measuring beam passing through a bi-prism 70 and being received by a photo-electric device 66 or 68 depending on whether the beam is upwardly or downwardly displaced. A modification is described in which the photo-electric devices move with the sensor to ensure that the same sensitive area of each photo-electric device remains activated as the sensor traverses the workpiece. Apparatus is also described for tilting and moving vertically the plate 62 in order to bring the beams into alignment with the workpiece surface. A modified form of the apparatus for measuring curved surfaces and optical devices for homogenizing the beam when the source is a laser are described.

Filed: 1970-12-21
Abstract: 1331626 Valves; braking systems WESTINGHOUSE BREMSEN-UND APPARATEBAU GmbH 21 Dec 1970 [20 Dec 1969] 60498/70 Addition to 1294987 Headings F2F and F2V A tractor multicircuit braking system incorporates a relay device 11 which serves as a trailer brake valve and acts to control the pressure in a trailer direct brake line 18 in response to the pressures in the circuits I, II of the trailer braking system and also in response to the pressure in a spring power auxiliary circuit III. A valve 3 controls the circuits I, II which incorporate respective storage tanks 2 and 5 and which respectively operate cylinders 4, 4<SP>1</SP> for the front wheels and the rear wheels, and a manually operable valve 101 is included in the circuit III incoporating a storage tank 102 which valve 101 on actuation vents the cylinders 4<SP>1</SP>. The relay device 11 includes two coaxially arranged relay pistons 53, 54 and the piston 53 consists of two parts 104, 105 connected together by a guide sleeve 57, and the relay piston 54 consists of two ports 60, 61. A double valve element 67 forms an inlet valve 56, 68 in conjunction with a valve seat 56 on the piston 53 and an outlet valve 66, 69 in conjunction with a valve seat 66 on the piston 64. The brake circuit I communicates with a chamber 73 above the relay piston 54, the second brake circuit II communicates with a chamber 76 below the piston part 105 and the valve 101 by way of line 103 communicates with a chamber 110 above the piston part 105, and this chamber 110 is normally charged with the pressure in the circuit III when the valve 101 is not actuated. The supply tank 102 communicates via a line 14 with a chamber 79 below the piston part 104 and a chamber 80 above the piston part 104 communicates with the direct trailer line 18. When the valve 3 is actuated air from tanks 2 and 5 enters cylinders 4, 4<SP>1</SP> to brake the tractor and also enters chambers 73, 76 in device 11 and with either or both of the circuits I, II operative the pistons 53, 54 move relative to one another to cause inlet valve 56, 68 to open and outlet valve 66, 69 to close: air then flows from chamber 79 into chamber 80 and thence into line 18 to actuate the trailer brakes in advance of the tractor brakes. An equilibrium is established with the double valve 56, 68 and 66, 69 in a terminal position but when the valve 101 is actuated to vent the cylinders 4<SP>1</SP> this equilibrium is disturbed and the inlet valve 56, 68 is opened until a pressure proportional to the resultant pressure decrease in chamber 110 is fed to the line 18.

Filed: 1969-12-11
Abstract: 1287306 Cooling whilst blending BAKER PERKINS Inc 11 Dec 1969 [12 Dec 1968] 60533/69 Heading B1C [Also in Divisions Cl and F4] A method of cooling a mass, e.g. a carbonaceous particle-pitch mass, whilst blending it comprises introducing a liquid coolant into the mass, keeping the mass under a pressure sufficient to prevent vaporisation of the liquid coolant while blending the latter with the mass and passing the blended mass to a region of lower pressure so that the liquid coolant vaporises and thereby reduces the temperature of the mass. As shown, a carbonaceous particle-pitch mass may be fed via hopper 10 into the bore 11 in the barrel B of a mixer M. The barrel may be provided with teeth 12, 12' which are circumferentially spaced and project radially inwardly and which cooperate with interrupted helical threads or blades 13 on shaft 14, which is simultaneously rotated and reciprocated. One of the teeth may be provided with a bore through which liquid coolant, e.g. water or carbon dioxide, is injected into the mass in the bore of the barrel. The latter may be provided with annular passages 9, 9a through which heat transfer fluid(s) may be circulated. The temperature of the fluid circulated through passage 9a may be less than that of the fluid passed through passage 9. The blended mass may be discharged from the barrel into a section 24 open to atmosphere in which the liquid coolant vaporises and further mixing is continued before exit through opening 28. The rate at which liquid coolant is added may be regulated according to the temperature of the blend discharged through opening 28, the temperature being measured by means of a sensor 39.

Alternatively, in a drying cabinet, a stationary enclosure is provided for the clothes, through which heated air is passed upwardly. The moisture in a proportion of the air is again condensed in an air-cooled heat pipe device before recirculation. <IMAGE>
