Filed: 1970-06-05
Abstract: 1319481 Road surface marking machines LA LIGNE BLANCHE 5 June 1970 [6 June 1969 24 Feb 1970] 27317/70 Heading E1G In a wheeled road surface marking machine (not shown) wherein the road is marked by material discharged under gravity from a smoothing applicator (not described) which can be raised and lowered on the machine, (a) the road wheels are driven by a fluid motor 10 supplied through a variable throw reversible pump 1, and (b) the material-discharge and applicator-lifting are controlled by a single fluid pressure jack 20 associated with a time delay device 21 which provides a time delay between the initial and final portions of the jack stroke, so that after the discharge has been stopped (by initial movement of the jack) there is a time delay before the applicator is lifted (by the final movement of the jack)- thereby providing a smoothed'finish. The time delay device 21 shown comprises a hydraulic accumulator 25 having an internal diaphragm and an air chamber 26 fed from a compressor or a gas container. The machine may comprise a tricycle carrying an internal combustion engine and having, in addition to the gravity applicator, three spray guns respectively for (a) a product promoting adhesion of the gravity-applied marking material; (b) a reflective product (e.g. ballotini); and (c) a sprayable marking material (e.g. paint). In the hydraulic circuit of Fig. 1 the wheeldriving motor 10 is supplied from pump 1 through change-over valves 12, 13 associated with a by-pass 14 used to stop the machine. The pump 1 and motor 10 are protected by overload valves 16a, b; 17a, b. Losses from the system are made up by a pump 2 which acts as a "force pump" for the pump 1. The prime mover (not shown) for pumps 1, 2 also drives a pump 3 which (a) supplies a motor 27 driving a compressor 28 for the spraying circuits Fig. 2 (not shown), and (b) actuates the hydraulic jack 20 through an electrically-operated valve E1 and the timedelay accumulator 25. Fig. 4 (not shown) illustrates a hydraulic circuit which is alternative to that of Fig. 1. The pneumatic circuit, Fig. 2 (not shown) indicates supplies and electrically controlled valves for the three spray guns (38, 43, 37), and for a pneumatic jack (39) which raises and lowers stencil discs (48) between which the paint spray gun (37) is in use mounted; Fig. 2 also shows a paint mixer (50) driven by a hydraulic motor (M) fed from the take-off R 1  shown in Fig. 1. The three spray guns are controlled electrically by a circuit, Fig. 3 (not shown) which includes series of cam-actuated switches (53a..h; 54a..h) frictionally driven from a road wheel (57) whereby different programmes of automatic intermittent road marking may be selected; there is also provision for remote-control manual override (e.g. when renewing existing markings).

Title: Improvements in or relating to stuffing box packings
Inventor: RADKE RUDOLF
IPC: F16J15/20
Filed: 1958-08-26
Abstract: 832,156. Stuffing-box substitute. KIND, P., and KIND, A., [trading as FRANKFURTER ASBESTWERKE P. KIND K.G.]. Aug. 26, 1958, No. 27333/58. Class 122 (5). [Also in Group VIII] A stuffing-box packing ring is punched out of a cardboard-like sheet of fibrous material in which every single fibre is practically completely enclosed in a finelydistributed solid lubricant. The fibres may be of asbestos, glass, glass wool, cotton, jute or synthetic materials, and the solid lubricant of graphite, talc, mica, molybdenum bisulphide, or ductile metals in powdered form. A bonding agent is generally used in conjunction with the solid lubricant in the manufacture of the sheets and may be of natural or synthetic rubber, resins or animal, vegetable or synthetic glues. The fibres may be coated with the solid lubricant by immersing them in a pulp containing the lubricant and the bonding agent or by dusting or blowing the lubricant on to fibres already treated with the bonding agent. The cardboard-like sheet is then formed from the treated fibres in a paper-board machine. The packing rings which are punched out of the dried sheets by a suitable press-tool, may have rectangular, square, round or U cross-section and have their peripheries split in various ways to facilitate assembly. As shown in Fig. 14, the rings 19 are mounted between metal rings 20, 21. The material from which the packing rings are made may include chemicals such as silicons or synthetic oils in order to increase its resistance to the particular substance being sealed.

Title: Shaft furnaces
IPC: C21B7/08
Filed: 1972-06-13
Abstract: 1344756 Throat armour for shaft furnaces GUTEHOFFNUNGSHUTTE STERKRADE AG 13 June 1972 [16 June 1971] 27466/72 Addition to 1320623 Heading F4B The segmented throat armour of a shaft furnace comprising an inner row of segments 3, alternating with and overlapping an outer row of segments 3a (Fig. 3) is adjusted by members 7 connected to each segment and controlled by drive means operated through a distributer so that a timing difference is produced between the movement of each row of segments only at the beginning and end of the adjustment, the two rows being moved together while spaced apart for the greater part of the adjustment movement. Each segment 3 is hinged to the furnace structure at 5, and connected by a rod 7, bell crank 10, 11 and a connecting rod 12 to a ring 13 sliding on the outside of the furnace. The inner segments are connected to an upper ring 13 moved by hydraulic pistons 14, while the outer segments are connected to a lower ring 13a moved by pistons 14a. The ring 13 is first raised a small amount, then both the rings 13 and 13a are raised together until the inner segments reach their final position, and the ring 13a is moved until the outer segments are in contact with the inner segments. To simplify the hydraulic distributer system, the outer segments may be moved outwardly to form a gap between the two sets of segments before they are moved together so that the inner segments reach their final position. This may be achieved by connecting the ring driving the outer segments to that driving the inner segments by hydraulic pistons, so that separation of the two rows of segments is obtained by relative movement of the two rings, one set of pistons moving both sets of segments through their respective rings.

Title: Improvements in or relating to stellar orientation detector
IPC: G01S3/787
Filed: 1956-09-07
Abstract: 848,692. Photo-electric determination of direction. NORTH AMERICAN AVIATION Inc. Sept. 7, 1956, No. 27534/56. Class 40(3). In order to generate voltages indicative of the deviation of the axis of an optical system from a line of sight to a star, light from the star is split into two beams each directed on to a respective photo-electric cell and means are provided to modulate each beam with a phase relation dependent on both the magnitude and sense of said deviation. The optical system comprises an objective lens 1, Fig. 1, and beam-splitting prisms 2, 3, the light from which falls on photocells 10, 11 respectively after being modulated by rotating reticles 4, 5 respectively. The reticles 4, 5 Fig. 2 are formed with two and three apertures, respectively, bounded by Archimedes spirals having curvatures in the ratio 2:3 and are driven by gears 7, 6, respectively, from gear 9 and motor 8 at speeds in the ratio 3:2. The generator 12, driven by the motor 8, produces a signal S 3  of standard phase at the same frequency as that of the signals S 2 , S 1  respectively arising in the photocells 10, 11, due to the modulation of the light beams by reticles 4, 5. Signals S 1 ,S 2  are fed to a differential synchro 19, Fig. 3, the shaft output of which corresponds to the phase difference # between the signals and hence to the star image angle measured clockwise from the positive Y-axis Fig. 2. This shaft output is doubled by gearbox 20 and causes the phase-shifter 14 to shift the phase of signal S 3 , applied thereto, by an angle 2#. The output S 4  from phase-shifter 14 is fed, together with signal S 2 ,to a differential synchro 16 the shaft output of which is thus proportional to #, the phase angle due to the spiral curvature of the reticle apertures. A mechanical computer 15 receives the quantities # and # as shaft rotations and produces therefrom the rectangular coordinates, y = K# cos # and x = K# sin  # ,of the star image in the telescope field, which may be 'used to change the telescope orientation so that  its optical axis coincides with the line of sight to the star. Details of a suitable mechanical computer are described, Figs. 5, 6, 7 (not shown). In a modified form of reticle, the spiral portion of the apertures occupies only the central portion, the remainder of the aperture being sector-shaped Fig. 4 (not shown). The modulation effect of a  uniform sky background light or a linearly varying background light is avoided by the fact that the centroid of the apertured area of a reticle coincides with the axis of rotation. Specification 848,691 is referred to.

The firebox 2 has a sliding door 10 for charging with fuel and a sliding door 8 for regulating the admission of air through an aperture 9, additional air openings 91 also being provided. The products of combustion leave through an aperture 3 having baffling means snch as flanges 7 which prevent dust reaching the food, and which may have a sliding shutter or like means for varying the opening. The firebox 2 slides into and out of the chamber 1 under the cover 4 which may be lined internally with asbestos or similar fireproof material. The combustion products pass from the chamber 1 to the main flue 12 through an outlet 11, with a canopy 13, which may be hinged, and a sliding shutter 14 for regulating the draught. In a modification, the charging door of the firebox may be a hinged canopy disposed in front thereof. To adapt the chamber for pale drying an outlet disposed higher than outlet 12 and having a baffle-plate may be provided.

Title: Improvements in or relating to automobile automatic clutches
IPC: F16D47/06
Filed: 1955-09-28
Abstract: 785,395. Clutches. SOC. ANON. FRANCAISE DU FERODO. Sept. 28, 1955 [Sept. 28 1954], No. 27671/55. Class 80 (2). An automatic clutch device comprises a main and auxiliary coupling, the auxiliery coupling having paralleled one-way and torque-limiting means, the latter being disengaged at will. A vehicle engine shaft 10 carries a flywheel 15 to which are secured pivots 18 of a series of centrifugal clutch shoes 17 engageable with a clutch drum 20 and held out of engagement at low speeds by springs 21. The drum 20 is secured to the yoke 24 of an electromagnet which is free for rotation on a bush 25 surrounding a gear-box input shaft 12. The yoke 24 is connected for rotation in the normal direction with shaft 12 by a free-wheel 28, and is associated with an armature 30 mounted for relative lateral movement and part for rotation with the yoke. Between two friction plates 31, 32 connected respectively with the yoke 24 and the armature 30, is a friction disc 33 secured for rotation to the shaft 12. The plate 32 carries two collector rings 35, 38 connected to the winding 34 of the electromagnetic clutch which is designed to transmit a torque only slightly greater than that produced by the compression of the engine. The brush 36 is earthed at 37, and the brush 39 is connected to the battery circuit 40 of the vehicle through a relay 41 which cuts off the current to the clutch and the engine ignition system while the gear-lever 14 is being moved. During normal running engine torque is transmitted by centrifugal clutch 16, one-way clutch 28 and torque-limiting clutch 34 to the shaft 12 of the gear-box 13. On over-run the one-way clutch 28 is free and transmittable torque is, limited by the clutch 34. For gear-shift lever 42 is moved, relay 41 opens and clutch 34 is released simultaneously with cutting of the ignition system B. In a modification, a direction responsive switch is incorporated in the clutch to free the clutch 34 during normal running. In a second embodiment, Fig. 11, the centrifugal clutch 16 is replaced by a fluid coupling 50, 51 and the electromagnetic clutch 66 is disengaged against spring pressure when the gear lever 14 is moved, simultaneously with this disengagement a brake is applied to the driven member 51 to prevent drag. In this embodiment the ignition system is not affected by gear-shift, but closing of relay 74 energizes a solenoid 75 closes the throttle 78 against a spring 80 which normally provides usual control from accelerator 79.
