Title: Fiber forming bushing construction
IPC: C03B37/085
Filed: 1979-03-21
Abstract: In an open topped low temperature electrical resistance bushing 10 having an aperture base plate 12 joined to upstanding end walls provided with supply terminals and upstanding side walls 14, 16 the average thickness of the base plate 16 is at least four times the average thickness of each side wall 14, 16 and the cross sectional area of the base plate is at least 45% of cross- sectional area of the side walls and base plate together, so that it is possible to maintain both the base plate and the side walls in the temperature range 2000-2500 DEG F and thus use alloys other than high temperature rhodium-platinum for the bushing. Stainless steel or nickel chrome alloys can be used for the bushing. In a marble-melt bushing a funnel is mounted on the top of the bushing and a cooling tube is mounted adjacent the bottom of the funnel. Auxiliary end plates may be mounted adjacent the end walls of the bushing for directing electrical current directly to the base plate. The opposed side walls may be inclined outwardly. Upper side wall sections are inclined inwardly from an associated side wall. <IMAGE>

Patent GB-2043709-A (GB)
Title: Colouration of textiles
IPC: D06P5/24
Filed: 1980-02-21
Abstract: A method of colouring textiles comprises pressing onto a textile fabric a flexible substrate, preferably silicone treated paper, having a removable layer thereon containing a dyestuff a polyvinyl alcohol soluble in hot water and sufficiently soluble in cold water to enable it to be washed off the fabric. After pressing, preferably carried out in a steam press, the substrate is removed leaving the layer on the fabric. The fabric and layer are then heat treated to fix the dyestuff. Surplus layer components are washed from the fabric using water below 60 DEG C containing a small quantity of detergent. The process is particularly suited to natural fibres, e.g. keratinous fibres, and in this case the dyestuffs employed may be acid, reactive or premetallised dyes.

Title: Electrical fittings
IPC: H01R33/46
Filed: 1980-07-25
Abstract: An electrical lampholder composes inner (13) and outer (11) insulating body parts that sandwich a metal lamp cap retainer sleeve (12). Outward flanging (22, 23; 18, 19) of the inner body part and the sleeve fit over edges of interior recessing (27, 28) of the outer body part. The sleeve is secured against any displacement relative to the inner body part by bending over tabs (20, 21) of the sleeve into recesses (24, 25) of the inner body part. Relative displacement of the inner and outer body parts after assembly is prevented by capture formations (30, 31) of the outer body part under which, after initial axial movement, flanges (22, 23) are moved to abut stops (36), the flanges (22, 23) being locked in place by a further part (42). Alternatively the inner and outer body parts may interfit against relative rotation and be secured axially by spring means temporarily displaced during assembly. <IMAGE>

Title: Improvements in rotary sealing devices
IPC: F16J15/34
Filed: 1980-07-28
Abstract: A rotary pump for forcing the cooling water to circulate through the cooling system of an i.c. engine is driven by a rotary drive shaft (14) which extends into the pump through a bearing (22). A rotary sealing device (24) between the rotary drive shaft (14) and the stationary housing (23) of the pump prevents water escaping from the pump through the bearing (22). The rotary sealing device (24) has a stationary annular face seal member 26 which is sealingly mounted in the pump housing so as to be coaxial with the rotary drive shaft (14), and an annular counterface member 25 sealingly mounted on the drive shaft (14). The face seal member 26 and the counterface member 25 are held resiliently together at respective opposing sealing faces 28,29. A coaxial shroud 37 is secured to the counterfoil member 25 to shield the faces 28 and 29 from approaching abrasive particles and is equipped with an outwardly extending flange 38 arranged to accelerate water and particles away from the sealing device (24). Water for cooling the members 25 and 26 is allowed to flow within the shroud 37, leaving the shroud 37 through apertures in portion 39 thereof. <IMAGE>

Title: Enclosures with a Gas Extraction System
IPC: B08B15/02
Filed: 1981-03-24
Abstract: In a row of fume cupboards each fume cupboard 2 is closed by a door 4 and connected by a respective duct 5 and a common manifold 3 to a common air extraction fan 24. Within each duct 5 there is a rotatable damper 6 connected to an electric motor which incorporates a potentiometer. Incorporated in a sensor member adjacent the door is a plurality of magnetically actuated switches each associated with a respective resistance of a resistance ladder 10 and with a magnet which normally holds the switch closed. As the door is opened a plate secured to it progressively comes between the switches and their associated magnets thus permitting the switches to open and increasing the resistance of the resistance ladder 10. This resistance, which is indicative of the position of the associated door 4, is connected to an amplifier which moves the electric motor and thus the damper 6. The outputs of the potentiometers are summed by a summing amplifier 26 whose output varies the speed of the fan 24. <IMAGE>
Patent GB-2097197-A (GB)
Title: Combined motion drive unit
IPC: H02K37/00
Filed: 1981-03-27
Abstract: A combined motion drive unit (10) comprises two rotary electric stepping motors (28, 30) arranged in a common casing. The motor (28) includes a rotor (36) fixed to a shaft (18) of the unit whereby the shaft (18) can be rotated to any one of a desired plurality of angular positions by energising the motor (28). Fixed to a rotor (42) of the second motor (38) is an externally threaded sleeve or lead screw (44) received in a nut (46) fixed to the casing. When the motor (30) is energised, the rotor (42) thereof and the lead screw (44) rotate, whereby the lead screw (44) is screwed into or out of the nut (46) with the result that circlips (52, 54) cause corresponding axial movement of the shaft (18) without subjecting the shaft (18) to rotary movement. The shaft (18) can thus be moved axially in predetermined steps corresponding to the step positions of the motor (38). The above-described rotational and axial movements of the shaft (18) are mutually independent. <IMAGE>
