Patent GB-866352-A (GB)
Abstract: 866,352. Drying apparatus. PHILLIPS PETROLEUM CO. Dec. 1, 1958 [Dec. 2, 1957], No. 38629/58. Class 34(2) A process for separating polymer solids from liquids comprises passing a solidsliquid mixture consisting of solid polymer, water and hydrocarbon solvent in an upwardly direction in a confined zone, and contacting the mixture with a stripping gas during at least a part of said passage of said mixture through said zone and withdrawing polymer solids of reduced moisture content from the upper portion of the zone. In the apparatus shown a solution of polyethylene in a hydrocarbon solvent is injected into a stream of water flowing through a tee 20, Fig. 1, at such a temperature that polymer precipitation occurs. The hydrocarbon is vaporized in a vessel 27 by steam entering through a conduit 30 and the polymer-water-residual hydrocarbon mixture passes to a skimming tank 40 from the top of which a steam heated screw conveyer 59 moves the' wet polymer upwardly in countercurrent to steam from a pipe 76, Fig. 2. The resulting vaporized solvent and water is conducted to a condenser 80 through piping 77, water and solvent being recovered from a vessel 81 whilst non-condensibles and uncondensed vapour are drawn from the vessel through a conduit 83. Damp polymer enters a drier 51, Figs. 1, 3, through a conduit 50 and from thence passes to an extrusion cooling and cutting unit 55. In a modification steam from the pipe 76, Fig. 3, flows with the wet polymer along the conveyer 59 and nitrogen is introduced, if desired, into the conduit 50 through piping 89. Steam, vaporized solvent and nitrogen is withdrawn through the piping 77. The conveyer may comprise a single or double auger or a bucket conveyer. Steam temperatures in the conveyer path may be between 170 and 191 ‹C.

Abstract: The system includes a brushless electronically commutated motor (29); and control means (30) for controlling the motor and thereby the door in dependence on control inputs. As shown, a microprocessor 42 controls the motor (29) according to a motion profile in an EPROM (41); control pulses incrementing an internal register which is decremented by feedback signals obtained from a Hall effect commutation encoder associated with the motor (29). Provision is made for halting the doors in the event of an obstruction, for initiating door operation through user sensors (50,51), for mode selecting (52) (ie automatic entrance and exit; exit only; hold open; hold closed) and for operating other doors via a serial data link (53).

Title: Air-excluding paint-pot and brush holder
Inventor: SNELL ROLAND THURSTON
IPC: B44D3/12
Filed: 1987-10-10
Abstract: A cylindrical paint container 1 has a combined plunger 2 and brush container 5, a central hole allowing paint to pass into the brush container 5 when the plunger is depressed and after all the air has been expelled. The level of paint in the container 5, which is designed to easily accept the brush 6-9 being used, is maintained at a high level by manual pressure on the plunger. The paint brush, which is dipped into and also stored in the container 5, has a stopper 7 to fit the top rim of the container 5, sealed around the lower part of its body adjacent its bristles, so that after all air has been expelled from the two containers, an air-tight seal can be made, keeping paint and brush in an air-free environment until they are next required. The plunger may include scraper sealing rings 3 or may be attached to a flexible paint containing bag fitting inside the container (Figure 3). The brush container may be screwed into the centre of the plunger 2 to allow for different sizes of brush containers. An ordinary stopper may be used to seal container 5. <IMAGE>
Patent GB-876424-A (GB)
Abstract: 876,424. Automatic control systems for gyroscopes. GENERAL ELECTRIC CO. Sept. 4, 1958 [Sept. 6, 1957], No. 28444/58. Class 38 (4). [Also in Group XXXVIII] A rate-of-turn signal is produced by an electrical generator driven at a speed proportional to that of a shaft which is maintained by a servo system in positional correspondence with an inertial reference slaved to a magnetic compass. In Fig. 1, signals from an inductive pick-off 9 associated with a directional gyro 2 on a craft are applied to a variable inductive device 13, the rotor 14 of which is driven to a null position by a two-phase servomotor 17 energized by signals from rotor 14 through an amplifier 15. Shaft 8 of rotor 14, which thus follows movements of the gyro relative to the craft, positions rotor 23 of a variable inductive device 22, signals from the stator 24 of which may be used to operate a remote direction indicator or control an automatic pilot. Shaft 8 also positions the rotor 7 of a variable inductive device 6 which receives signals from an earth inductor compass 1 so that signals from rotor 7, representing gyro wander, are applied through an amplifier 19 to a torque motor 21 correcting the gyro by precession. An A.C. generator 26 driven by servomotor 17 produces signals, representative of rate of turn of the craft, which operate a relay 31 through an amplifier 30 so that the correcting system for the gyro is disabled when rate of turn exceeds a predetermined value. The relay may also disable a system (not shown) for automatically levelling the gyro. Signals from generator 26 may also operate a rate of turn indicator and/or stabilize the operation of motor 17. In one modification, signals from a variable inductive device operated by an intermediate shaft of the gearing between motor 17 and shaft 8 operates a further follow-up servomotor which drives the rate of turn generator. In another modification, compensation for wander of a gyrostabilized platform in azimuth is effected by varying an inductive device connected in cascade between a platform pick-off and the input to a follow-up servomotor instead of correcting the platform itself. In this modification also a separate follow-up servomotor is employed to drive the rate of turn generator.
