Title: Automatic circumferentially adjustable coupling
IPC: F16D3/10
Filed: 1963-10-10
Abstract: 1,026,309. Fluid-pressure servomotor systems. BENDIX CORPORATION. Oct. 10, 1963 [Oct.12, 1962], No. 40068/63, Heading G3P. [Also in Divisions F1 and F2] In a circumferentially adjustable coupling for automatically controlling the timing of an I.C. engine fuel injection pump in response to speed, a sleeve 26 having straight and helical splined connections 27, 29 respectively with an engine-driven shaft 11 and a pump-driving shaft 12 is axially moved to adjust the circumferential relationship between the shafts 11, 12 by fluid pressure which is supplied to a servo cylinder bounded by the  sleeve 26, an end plug 30 welded or brazed therein, and the shaft 12 and is regulated by a follow-up valve comprising a sleeve 57 axially moved by centrifugal balls 71 to throttle a cylinder outlet port 55 in the sleeve 26. The cylinder is energized by engine lubricating oil through an inlet port and removable orifice in a fixed plate 15, a radial port and annular groove 41 in a collar 43, and a passage 42 and flared opening 45 in the shaft 12. The outlet port 55 is always in communication with the cylinder through an annular groove 54<SP>1</SP>, a radial port 54 and the passage 42. The balls 71 act and react, respectively on a cone 70 integral with the valve sleeve 57 and a flange 69 secured to the shaft 12, to leftwardly move the sleeve 57 against a spring 62 alone at low speeds and springs 62, 64 together at higher speeds. The position of the sleeve 26 is determined by the leftward hydraulic force and rightward torque responsive thrust developed by the splines 29 which latter thrust may be supplemented by a spring 34 damping sleeve movement. Changes in torque reaction effect only insignificant changes in injection timing, a slight movement of the sleeve 26 due to change in torque reaction resulting in change in servo cylinder pressure.

IPC: F42B4/28
Filed: 1960-11-22
Abstract: 940,479. Pyrotechnic and like devices; projectiles. GOTEX A. B. Nov. 22, 1960 [Nov. 25, 1959], No. 40114/60. Heading F3A. A container 1 having end caps 4, 5 houses a rocket device comprising an outer casing 19, propellant 18, tail fins 25, an inner casing 20 to house the pay-load 21, for example, an illuminating composition, and a parachute 27 placed between the casings 19, 20. At the base of the container 1 is a plate 6 which supports a guide socket 7 for a striker pin 8. The latter is retained rearwardly against the action of spring 12 and on being released, by rotating cap 2 which causes a spring lever 9 to be withdrawn from a diametral bore 11, moves upwardly to detonate a primer 13 in nozzle 14 of the rocket. Consequent ignition of the propellant 18 clears the nozzle and forces the rocket out of the container 1, cap 3 having been removed beforehand. A delay fuze material 18<SP>1</SP> is ignited as the burning of propellant 18 terminates and this in turn ignites the illuminating composition 21, the combustion gases from which are sufficient to eject the casing 20 and the parachute 27 together with its suspension cords 29 and damping device 30 from the rocket casing 19. The damping device 30 comprises two back-toback plane spiral springs, their outer coils being connected together and their inner coils being connected respectively to a plug 32 and to the suspension cords 29. The rocket is stabilized in flight by the fins 25, which open out on leaving the container 1.

Title: Improvements in the production of regenerated cellulose fabrics
Inventor: BEAUMONT CLIFFORD
IPC: D06M23/00
Filed: 1963-10-11
Abstract: Fabrics having attractive visual effects are produced by weaving a fabric having an aggregate cover factor of at least 160 from regenerated cellulose continuous filament yarns of which at least the warp or weft is of crosslinked regenerated cellulose, exposing the fabric to hot, aqueous conditions enabling yarn shrinkage and simultaneously or subsequently submitting the fabric, in the presence of a liquid, to agitation enabling relative movement of the yarns in the fabric.  The aggregate cover factor is defined as the sum of the cover factors calculated for the warp and weft, the cover factor in each direction being calculated from the formula C=N\stD in which C is the cover factor, N is the number of threads per inch and D is the denier of the yarn.  The crosslinking may be effected on the filaments in the form of a heavy-denier filamentary tow before or after they have been dried for the first time after their production, or they may be impregnated as never-dried tow with the cross-linking agent which may then be cured after the tow has been dried or after it has been converted into yarns.  Alternatively both the impregnation and curing may be carried out on the yarn itself. The cross-linking agent may be a ureaformaldehyde resin or reactant resin but is preferably formaldehyde catalysed by magnesium chloride or other metal salts, the warp and weft yarns being subjected to the same or different cross-linking treatments. The fabric may be exposed to shrinkage conditions by immersing it in a hot aqueous bath which may be a water bath or dye bath having a temperature of at least 70 DEG C, or by passing it into or through a chamber containing steam, optionally under pressure.  The agitation may effected in a washing machine or on a dyeing winch.

Filed: 1959-11-27
Abstract: 905,686. Door closers. COURTNEY, POPE Ltd., and LYON, C. R. Nov. 24, 1960 [Nov. 27, 1959], No. 40453/59. Class 65 (1). A door closer comprises a cam 17 actuated by the door and operatively connected with a spring-loaded dashpot by a pivoted lever 23, the surface of the cam being shaped as at 18, 19 to co-operate with the lever to releasably hold the door in the closed position and in the fully open positions corresponding to both directions of opening. The lever has a camengaging roller 21 and is pivotally connected at 26 to the rod 28 of the dashpot piston which comprises a synthetic rubber washer or 0-ring seal 30 freely disposed between a metal backing collar 31 and a disc 29. The dashpot cylinder 32 is pivoted at its closed end on a pin 35 in the inner box casing 3 of the closer which has a thin boss 4 (Fig. 1, not shown) axially aligned with the closer spindle 14 and pivotally received in a suitable mounting-plate at the bottom of the outer box 1. Inclined slots 10 in the flange 6 of the inner box 3 are engaged by clamping screws 56 so that the inner box and closer mechanism can be angularly adjusted to vary the normal closed position of the door. When the door is being opened and the piston moves away from the closed end of the cylinder, the 0-ring 30 is forced into engagement with the disc 29 and oil contained in the box 3 is drawn into the cylinder through holes 55 therein and flows through the gap between the collar 31 and the 0-ring 30, under the latter, and through a hole or holes, not shown, in the disc 29. When the door begins to close under the action of the spring 36 the 0-ring is forced into engagement with the collar 31 and closes the gap so that the oil trapped between the piston and the closed end of the cylinder can only escape through an adjustable valve 41 in the cylinder end. The valve has a limb 44 engaging a lever (not shown) operable from outside the cover-plate of the casing so that the checking action may be adjusted from outside the closer. A spring- loaded non-return ball valve 53 operates as a relief valve if the dashpot assembly is subjected to a sudden load. Specification 905,685 is referred to.

Title: An electrically controlled hydraulic brake system for a trailer vehicle
IPC: B60T13/18
Filed: 1965-09-27
Abstract: 1,082,742. Hydraulic brakes. FERRO MANUFACTURING CORPORATION. Sept. 27, 1965 [Dec. 28, 1964], No. 40931/65. Headings F2E and F2F.  In an electrically controlled hydraulic brake system for applying hydraulic fluid to wheel brake cylinders 18 of a trailer vehicle connected to a towing vehicle, a source of hydraulic pressure in the form of a motor pump and reservoir unit 20 supplies fluid under pressure through a solenoid-operated modulating valve 16 to meter the flow of fluid to the wheel cylinders 18 of the trailer vehicle. A control unit 12 mounted on the towing vehicle supplies an electric actuating signal to the solenoidoperated modulating valve 16 in accordance with the pressure applied on the brake pedal in the towing vehicle and in accordance with the pressure applied on the towing vehicle by the trailer vehicle. The solenoid-operated modulating valve 16 includes a spool valve member 42 which controls communication between the hydraulic fluid inlet passage 46 connected to a conduit 30 and an exhaust passage 48 connected to a conduit 26. The spool valve 42 also controls the flow of pressure fluid through the passage 50 leading to the towed vehicle wheel cylinders 18 through a conduit 36. When the solenoid 44 is energized the spool valve member 42 will be moved initially to its innermost position illustrated in Fig. 2 to close the exhaust passage 48 and connect the passage 50 to the inlet passage 46. Brake fluid will then be pumped through the conduit 28, accumulator 22, conduit 30, modulating valve 16 and conduit 36 to the trailer vehicle wheel brake cylinders 18 to apply the brakes of the trailer vehicle. When the pressure of the brake fluid in the wheel cylinders 18 of the trailer vehicle is at a predetermined pressure the  pressure on the end 72 of the spool valve move the latter to a position leftwards of that shown in Fig. 2, wherein both the inlet passage 46 and the exhaust passage 48 are closed. A third position of the spool valve exhausts the passage 50 to the passage 48, the inlet passage 46 being closed. A modification is disclosed in the Specification (Fig. 5, not shown), wherein a potentiometer is provided between the control unit 12 and the solenoid-operated modulating valve 16 for varying the electric signal applied to the solenoid-operated modulating valve in aecordance with a sensed pressure. A modified constant pressure pump, brake fluid reservoir assembly, and solenoid-operated modulated valve is described in the Specification (Fig. 6, not shown), wherein the spool valve is replaced by a ball check valve.

Title: Room status systems
IPC: G08B5/36
Filed: 1972-11-03
Abstract: 1368998 Selective signalling BRITISH RELAY Ltd 3 Nov 1972 [2 Sept 1971] 41073/71 Heading G4H A guest-room status-indicating system uses thyristors. Figure 9 embodiment.-Each hotel room contains a circuit as in Fig. 9, but with the different-coloured lamps 42, 43 being at a housekeeper station, with repeaters at reception. When the room is vacated, reception triggers on a thyristor SCR2 via 44 so lamp 42 flashes (due to negative pulses applied at 47). When a maid enters the room to prepare it, she inserts a jack at 50 thus triggering on a thyristor SCR3 via a transistor TR 7, lighting lamps 42, 43 via diodes D5, D6, D7 from a negative line at 46, and turning off SCR2. (53 can be connected to a pulsed negative line instead of to 46 as shown, to flash the lamps). When she has finished she removes the jack, so lamp 42 goes off, but 43 remains on via SCR 3. When the room is next occupied, reception makes a circuit 35 non- conducting to turn off SCR 3 and lamp 43. Figure 10 embodiment.-Each hotel room contains a circuit as in Fig. 10. When the guest is due to leave, reception turns on SCR5 via 75 so that negative pulses at 76 flash a red lamp at reception (via 69) and a red lamp at a housekeeper station (via 73). When the guest leaves, reception turns on SCR6 via 79 so the two lamps, go on steadily, due to a negative supply at 87. When a maid enters the room to prepare it, she inserts a jack at 78, thus turning on SCR7 via TR9, shorting off SCR5 and SCR6, and connecting a pulsed negative supply (or steady negative supply) 82 to red and green housekeeper lamps (via 73, 74). The green lamp (74) is also energized via SCR7 (continuously). The red reception lamp (69) is maintained on dim via a Zener diode D17 (replaced by a direct connection if full on is required). When the jack is removed, the red housekeeper lamp (73) goes off. The housekeeper, when satisfied that the room is ready for occupancy, inserts a jack at 84, turning SCR8 on, SCR7 off, the lamp connected to 69, 74 off, and a green reception lamp (and optionally a green housekeeper lamp) on via 70 and SCR8. Reception turns these lamps off by turning off SCR8 via 88 when the room is to be re-occupied. When the maid cleans the room daily, she inserts her jack at 78 which makes the red and green housekeeper lamps connected to 71, 72 flash. Triggering on of SCR8 could be conditioned by SCR7 via a transistor like TR9 (which conditions SCR7). Extra or alternative connections as shown dotted near the top of Fig. 10 could be provided. Modifications.-Lamps/audible-alarms may be provided in the rooms, controlled by thyristors set by reception and cancellable by reception or the guest.

Title: Coating electrically conductive e.g., metallic articles with organic coating material by electrodeposition
IPC: G01N1/00
Filed: 1964-10-09
Abstract: In coating a series of conductive production articles with an organic material by electrodeposition using D.C. and passing the articles through the coating bath in succession, the composition of the coating bath and the current density are adjusted in accordance with the indications of the coating obtained by D.C. electrodeposition on a test article passed through a test tank containing coating material drawn from the main coating bath. Preferably the ratio of the surface area of the test article to the volume of coating material in the test tank is much larger than that of the surface area of the production article to the volume of the main bath, while the current density in the test tank is higher than in the main bath.  The coating baths are typically water-thinnable paint dispersions containing (a) resins including free carboxylic or sulphonic acid groups and solubilized with ammonia or amines or (b) resins including amine or quaternary ammonium groups and solubilized with carboxylic or phosphoric acid, thus providing anodically and cathodically depositable compositions respectively which are subsequently baked. As described paint is supplied from a common tank to both the production and test coating units.  In the latter the test article which forms one electrode is one or more steel strip each with feed perforations fed in a loop between drive sprockets through the test bath the test tank and a secondary electrode within the loop forming the counter electrode.  Provision is made for externally circulating the test bath liquid for changing its temperature and subjecting it to ion exchange treatment, e.g. to remove excess free amine or ammonia liberated in the coating process, or dialysis treatment, and also for returning the paint composition to the supply tank.  The length of test strip passed may be measured and the test bath pH continuously monitored.
