Title: Fountain pen
IPC: B43K8/02
Filed: 1966-07-19
Abstract: 1,109,022. Reservoir pens. TEXTRON Inc. 19 July, 1966 [22 July, 1965], No. 32334/66. Heading B6P. [Also in Division A4] The overflow control member 62 of a reservoir pen comprises a generally cylindrical porous body axially apertured for the passage of the capillary feed member which transfers ink from the reservoir to the marking point or nib. The control member 62 comprises a multiplicity of ink wettable particles bonded together at their points of contacts. The particle, e.g. polypropylene particles, may be lightly packed into a moulding die of the desired configuration, which die is then heated sufficiently to cause softening and subsequent bonding together of the surfacecontacting portions of the particles. The spaces or cells so provided are randomly distributed and of various sizes, and comprise preferably about 40% to 75% of the total volume of the control member 62. A certain percentage, about 10% to 60%, of the total spaces form storage cells, and the remaining spaces, which are of lesser width and therefore greater capillarity, form a vein-like network of capillary passages by means of which ink is distributed throughout the control member 62 to its storage cells. In Fig. 1, the point 54 comprises a cylindrical rod of porous plastics material, e.g. a polyamide such as a fluorocarbon, and includes a writing tip portion 56 and feed portion 58 the rear end 60 of which extends through a pierce tube 44 into a cartridge reservoir 32. An air return channel is provided through the bore 50 surrounding the writing tip 56, Fig. 2, and rearwardly along the feed portions 58 and 60 between their outer peripheries and the inner surfaces of the adjacent control member 62 and the pierce tube 44. A semi-cylindrical venting channel 68 is formed along the outside surface of the control member 62. In Fig. 5, ink is drawn into a capillary channel 154 of a feed bar insert 150, whence it is transferred to a capillary slit 156 beneath the split nib 160. Air is drawn into the reservoir via an air scoop 164 formed in the head 140 of the feed-bar, then through a transverse aperture 178 and finally through an enlarged air passage 166 formed between a flattened area 152 of the insert 150 (Fig. 6) and the internal surface of the tubular feed-bar extension 144.

Title: Method and apparatus for measuring angles
IPC: H04L17/08
Filed: 1959-09-23
Abstract: 895,514. Measuring angular displacement electrically. MULLER, F. Sept. 23, 1959 [Sept. 23, 1958], No. 32449/59. Class 40 (1). [Also in Group XX] To measure the angle between the horizontal axis c-c, Fig. 2, of a vehicle wheel 11, and the plane b-b in which the wheel is located, a roller 10 is pressed against the periphery of the wheel, the axis of the roller being parallel to the axis c-c of the wheel, and the wheel 11 and therefore the roller 10, rotated. The wheel therefore exerts an axial force on the roller and if the roller is rotated until this force is zero its axis lies along the line a-a which is perpendicular to plane b-b, so that by measuring the angle through which the roller has been rotated, the required angle is determined. As shown, Fig. 6, axial force on the roller 40, which is mounted in self-aligning bearings 41, 43, causes a friction surface 55 or 56 to rotate a friction disc 58 in one or other direction and thus, by engagement of screw 59, carrying disc 58, with nut 63, to raise or lower a lever 50 which is pivoted at one end 51 to a support 52 and carries at its other end, through lever 44, the bearing 43. The angle is measured by meter 68, connected across a bridge circuit, in one arm of which is a variable resistance R 4  controlled by the roller 40. In a modification, Fig. 5, not shown, endwise movement of the roller actuates one or other of two sets of contacts controlling a reversible electric motor which through a suitable transmission raises or lowers one of the bearings for the roller.

Abstract: 1,197,212. Photo-electric interferometers. PERKIN-ELMER CORP. July 18, 1967 [July 18, 1966; June 7, 1967], No. 32911/67. Heading G1A. [Also in Divisions G4-6] An interferometer for indicating changes in length of an optical path comprises means for transmitting a first beam of light of predetermined polarization along the optical path and combining the transmitted beam with a second beam orthogonally polarized relative to the first to produce a plane polarized beam, the plane of which varies with variations in the optical path. Light from a laser 10, Fig. 1 is collimated by lenses 16, 18 and rendered circularly polarized by a quarter wave plate 20. The light beam is split by a half silvered surface 24 and one half is transmitted to a retro-reflector 14 mounted on the bed 26 of a machine tool. The polarization of the reflected light is reversed by the reflector 14 so that when it is combined with the other half of the split beam at the half silvered surface 28 a plane polarized beam results with plane dependent upon the position of reflector 14. The plane polarized beam is split by a half silvered surface 33 and passes to photocells 36, 38 through polarizers 32, 34 with their planes at 45 degrees. The two-phase signal produced by clippers 40, 42 drives a counter 44. The interference fringes may be viewed on a monitor 29. In a modification, Fig. 5 (not shown) the surfaces 24, 28 are of dielectric material. The beams transmitted and reflected by the surface 24 are then orthogonally elliptically polarized and recorders are inserted between the beam-splitters 27, 30 to produce the plane polarized output beam Ires. In another embodiment, Fig. 3 the beam Ires is focussed on a single photo-cell 36 through a birefringent plate 52 energized from an A. C. generator 54 so that the axis of the plate effectively rotates. The frequency of this rotation adds to frequency with which the plane of polarization of Ires rotates and this latter frequency is derived by feeding the photo-cell output and a reference signal from the generator 54 to the forwards and backwards inputs respectively of a bidirectional counter 44. In a modification, Fig. 4, (not shown) the photo-cell output is fed to a frequency measuring circuit to give an analogue indication of the velocity of the reflector 14.

Abstract: 1431773 Engine control systems LUCAS ELECTRICAL CO Ltd 2 July 1973 [15 July 1972] 33236/72 Heading G3N [Also in Division F 1] An engine control system for controlling an operating parameter such as fuel injection quantity or the timing of sparks, comprises at least two transducers 11, 12 producing outputs dependent upon the values of engine parameters, e.g. selected from throttle angle, manifold depression, and engine speed, a memory unit 13 to which the outputs are fed, the memory unit producing a binary output dependent on the signals received from the transducers, control means 15 operable in accordance with the value of the binary output for controlling the operating parameter, and a binary converter 14 coupling the binary output to the. control means, the binary converter changing the number of bits in the binary output so as to reduce the minimum attainable change in the operating parameter. The memory unit is shown in Fig. 2. The transducer 12 energizes one of lines 12a - 12d in dependence upon its analogue output. The lines 12a - 12d serve when energized to operate respectively four switches 16a - 16d and each switch serves, when it is operated, to couple one of four sets of four lines 17a - 17d to the output lines 13a - 13d. The transducer 11 also energizes one of four lines 11a - 11d in dependence upon its analogue output, each of the lines 11 crossing each of the lines 17 with selected connections being made between the two sets of lines by diodes. Thus depending upon which of lines 11a - lid and which of lines 12a - 12d are energized, an appropriate four-bit binary output is supplied on lines 13a - 13d. The converter (14), Fig. 3 (not shown), then converts the four-bit binary output to a five-bit binary output. The control means may be a fuel injection pump.
