Title: Apparatuses to separate mixtures of liquids of different specific gravities eg oil and water
IPC: B01D17/02
Filed: 1975-02-10
Abstract: 1469204 Apparatus for separating liquids MACHINEFABRIEK GEURTSEN DEVENTER BV 10 Feb 1975 [18 Feb 1974] 5592/75 Heading BID Apparatus for separating oil from bilge water comprises a central chamber 10 into which the mixture is delivered at 19 and which has an oil outlet 20 controlled by a valve (not shown), the lower part of chamber 10 being separated by one or more filter cloth sleeves 17, which resist passage of oil, from a chamber 18 which has an outlet 21 for water and is connected by pipe 22 with an upper chamber 9, separated from chamber 10 by a vertically movable diaphragm or bellows 8 sealed to the vessel wall. As oil accumulates against the underside of diaphragm 8 its buoyancy lifts the diaphragm actuating an external signal warning an operator to open the oil outlet valve or opening the valve directly. As shown the diaphragm is weighted by a plate 11 attached at its centre and connected to the actuating links 13-16. Before starting separation, the apparatus is completely filled with water, air vent 24 facilitating this, and chambers 9, 18 and pipe 22 remain filled with water thereafter. A normally closed sludge outlet 23 is provided.

A vibrating contact voltage regulator has an iron-hydrogen resistor connected across the contacts. There may be one such resistor, Fig. 1 (not shown), or two, 261, 26<SP>2</SP>, Fig. 2, may be connected in parallel together with a linear resistor 25. Relays 27<SP>1</SP>, 27<SP>2</SP> connect all resistors in parallel when the generator field current is high, and switch them out progressively as the current falls. In a modification, Fig. 3 (not shown), three iron hydrogen resistors are successively connected in parallel with a fourth by means of a single coil responsive to field current and controlling three relay armatures. The Specification as open to inspection under Sect. 91 also discloses, Fig. 2 (Cancelled), a tapped resistor 5 connected across the contacts 1, the value of the resistor being increased by a rolling contact 8 as the points open. It further discloses a number of resistors 261, 262, Fig. 9 (Cancelled), which are successively switched in parallel with the contacts 22 by an armature 29 actuated by a coil 27 in accordance with the field current. In a further modification, Fig. 10 (Cancelled, not shown), the resistors are switched by a drum-type controller. This subject-matter does not appear in the Specification as accepted.

Title: An improved quick-break motor protection switch
IPC: H01H3/02
Filed: 1945-03-07
Abstract: 588,749. Electrically tripped switches. LANDIS & GYR SOC. ANON. March 7, 1945, No. 5707. Convention date, March 13, 1944. [Class 38 (v)] The moving contact 16 of a motor protection switch bridges normally-fixed contacts 6, 7, which are moved away when a heavy overload occurs. Flexible leads 13 are connected to the contacts 6, 7 and therefore are not flexed during normal switching, when the contact 16 only is operated, by hand or by the armature of a switching magnet. The contacts 6, 7 with an insulating piece 8 form a movable structure biassed to the right by a spring 15, but latchedin by a half-cylinder 9 engaging a detent 11, the contacts 6, 7 being slidable within an insulating piece 5. When the core 3 of a quickbreak magnet 2 attracts an armature 4, the latter causes a lever 10 carrying the halfcylinder 9 to unlatch the detent 11 and open the switch. The contacts 6, 7, 16 are housed in a quenching chamber 1. Specification 588,724 is referred to.

[Class 103 (ii)] [Also in Groups XX and XXI] An optical instrument 1 for observing the rear visual field from the interior of an aeroplane is provided with an adjustable mark which may be continuously moved to coincide with the image of a pursuing aeroplane. As shown in Fig. 4, the adjustable mark is formed by the intersection of two bars 13, 14, carried by threaded sleeves 11, 12, mounted on the screws 7, 8. A similar and similarly adjusted pair of bars 25, 26, is provided in an instrument 20 mounted in front of the pilot 19. In use an observer 3 turns the screws 7, 8, by means of handles 9, 10, to keep the adjustable mark in coincidence with the image of a pursuing plane. A corresponding movement is transmitted by flexible cables 27, 28, to the adjustable mark in front of the pilot 19 who steers the aeroplane to bring the mark to the intersection of cross wires 29, 30. The observer may then operate a switch 34 to fire a gun mounted parallel to the longitudinal axis of the aeroplane. The adjustment of the mark may be transmitted from the observing instrument 1 to the indicating instrument 20 by hydraulic, electrical or optical means. '

Abstract: 1279223 Measuring angular acceleration electrically FERRANTI Ltd 19 April 1971 [6 Feb 1970] 5810/70 Heading G1N An angular accelerometer comprises an insulating disc 11, Fig.1, elastically supported in an electrically conducting liquid fed with an A. C. potential between top and bottom electrodes 18, 19, and two pairs of pick-up electrodes arranged along mutually perpendicular horizontal axes, whereby displacement of the housing 10 about one of the horizontal axes due to angular acceleration produces a potential difference between the pick-up electrodes on the other axis. The disc 11, strengthened by corrugations, is supported on a flexible strip 12 attached to the housing by post 13, cross-member 14 and post 15, angular displacement of disc 11 relative to the housing 10 occurring by bending and/or twisting of strip 12 about axes 22, 25, Fig. 2. The measured potential difference is directly proportional to steady angular acceleration, or the double integral of transient acceleration. Other embodiments show: (a) different electric support for disc 11, (b) modifications to the shape of disc 11 particularly for measurement of angular acceleration about one axis only, (c) an arrangement of three mutually perpendicular discs 11 for measuring displacement and acceleration about three mutually perpendicular axes, Figs.7, 8, 9 (not shown). The discs 11 may be made of electrically conducting material for use with a dielectric liquid and capacitive pick-ups.
