Abstract: 1,234,446. Distillation apparatus; desalination of water. AUSCOTENG PTY Ltd. 26 July, 1968 [26 July, 1967], No.35701/68. Heading BIB. Saline water is submitted to reduced pressure in evaporator 1, from the external walls of which external heat exchanger fins 2, whereby vaporization of water occurs at substantially ambient temperature; the vapours flow to condenser 10 from which the condensate (desalinated water) is from time to time withdrawn, together with air, by pump 22. Raw saline water is pumped through the coil 11 and jacket 16 of condenser 10, and some of the heated effluent water is then supplied to evaporator 1 through pipe 18 and float chamber 4. Waste brine is withdrawn from the evaporator by pump 20 whenever the density rises to a predetermined value. In Fig. 3, the condenser 60 is disposed inside the evaporator 61 which is provided with external fins 75, and direct heat transfer takes place between the condenser and the evaporator. A pump 76 draws vapour from the evaporator and discharges it into the condenser. The condensate flows down barometric leg 62, and the air is withdrawn through pipe 64 by pump 66. An apparatus is described which has the condenser of a refrigerator in the water-space of the evaporator, the refrigerator-evaporator being in the vapour space of the steam condenser.

Abstract: 1,234,519. Protective arrangements. AUTOMATIC SWITCH CO. 8 May, 1969 [12 July, 1968], No. 23413/69. Heading H2K. A directional relay arrangement for an A.C. line, e.g. for an alternator, comprises means 14 for producing a pulse at a predetermined point in each cycle of the current in a line conductor 10, means 15 to produce an output signal in response to a pulse, and means 16 to by-pass the pulses away from the means 15 during alternate half-cycles of a voltage which at unity power factor is displaced 90 degrees with respect to the current, so that an output signal is only obtained when the current is more than 90 degrees out of phase with the voltage of the conductor. In the three-phase arrangement shown, each current pulse is produced almost at current zero by a transformer 14 which saturates at a very small current in the conductor 10. When permitted, each pulse renders a unijunction transistor 29 conductive, so that a capacitor 32 can discharge through the transistor 29 to produce an output signal across a resistor 28. This is prevented when a transistor 42 is rendered conductive to short circuit the pulses away from the transistor 29, the transistor 42 conducting on alternate half-cycles of the voltage derived from a voltage transformer 49 connected across the other two phases 11, 12. In a single phase arrangement, a capacitor is used to provide the initial 90 degrees displacement between the voltage signal and the current, Fig. 3 (not shown).

Abstract: 1,251,611. Hydrostatic transmission control. S. R. CUDNOHUFSKY. 5 Feb., 1970 [25 April, 1969], No. 5475/70. Heading F2D. In an hydrostatic transmission, e.g. for a lathe, comprising a reversible variable-displacement pump 12 connected to a motor 14 through delivery and return lines 16, 18, a pilot-operated by-pass valve 58 connects the lines 16, 18 on reducing the pump 12 output to a predetermined low value or zero, e.g. when reversing the pump. The pilot-operated valve 58 is normally held closed by hydraulic pressure from a make-up pump 24 but, on moving the pump control lever 22 to neutral, a switch 74 is closed to actuate a solenoid 64 controlling a valve 62 which directs make-up fluid to open the valve 58. Pressure relief valves 52, 54 interconnect the lines 16, 18.

Abstract: 1,257,964. Sampling liquids. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 27 Jan., 1969, No. 4476/69. Heading B8N. [Also in Division B1] A sampling valve comprises a slide reciprocable in a housing between two positions, the slide having a passage or recess and the housing having liquid delivery and exit ports and a sample exit port. When the slide is in a first position the passage or recess communicates with the liquid delivery and exit ports, and in the second position the passage or recess is in communication with the sample exit port. The valve further includes means between the material delivery port and sample exit port for drawing liquid held between the slide and housing. As illustrated the slide 1 has an annular groove 10, and the housing includes liquid delivery and exit ports 3, 4, a carrier material inlet port 5, a sample exit port 6, and annular drainage passages 8, 12, 13 communicating via duct 11 with a port 14. An eccentric cam 16 rotated by an electric motor causes reciprocation of a carriage 14 on which the slide is mounted. Pin 19 prevents rotation of the slide. The slide may be driven by a crank or hydraulically or it may be operated electrically by a solenoid actuated by a timing switch. The passage 8 prevents seepage of liquid from the liquid delivery port 3 to the sample exit port 6, and is particularly advantageous, when a marker e.g. a radio-active chemical, a dye-stuff or chemically identifiable material is being used to indicate a change in the composition of the material being sampled, to prevent "smearing" of the marker.

A head 6 consisting of tubes soldered to one another is mounted at the front of the frame 1 and supports two lightweight hollow floats 9 pivotable independently of one another about a transverse tube 10 and provided with arcuate handles 8. An arcuate transverse support 20 for the body of the swimmer is mounted on the tube 12. There is also mounted on either side of the tube 12 a grooved member 22 in which the ends of a pedal 23 may slide longitudinally. To each pedal is attached a cable which, after passing over the two pulleys 27 and 28 is attached to an elastic shock absorber 29. The head 6 consists of a number of tubes 30 to 35 soldered to one another, the tube 30 being mounted on the tube 16 of the frame 1 in such a manner that the head 6 can pivot about an axis 7 with respect to the frame. The float 5 is provided with an aperture 39 for introducing water into the float to reduce the buoyancy of the apparatus. The aperture 39 is provided with a closure (not shown). The upper part of the float 5 is also provided with an inlet valve 40 through which air from a compressed air cylinder 38 mounted in the frame 1 may be introduced into the float, the water in the float being thereby expelled through the outlet valve 41 and the buoyancy of the apparatus increased. The two floats 9 at the front of the apparatus are each provided with a filling aperture 43, closure (50), inlet valve 44 and outlet valve (47) for the purpose of adjusting the buoyancy of the apparatus in the manner described with respect to the rear float 5. The rear of the float 5 is provided with a flat " fin " of a flexible material. Each of the front floats 9 is provided with a flat " fin " of a flexible material, whereby the apparatus may be caused to advance by rapidly oscillating the floats about the axis 10 to simulate the " swimming action " of flat fish. The mechanism in the housing 2 for driving the propeller comprises a bevel drive associated with two circular spring- loaded ratchet devices by means of which the linear reciprocating motion of the pedals 23 imparts a continuous rotary motion to the propeller shaft.

Abstract: 1,266,114. Testing cinematographic films. R. V. STEWARD. Oct. 26, 1970, No. 50854/70. Heading G2C.  A fault detecting apparatus 1 for cinematographic film comprises supply and take up spools 2, 3 with a film path therebetween; a guide 6 extending along a portion of the film path; a film drive mechanism 8, 9; brake control circuitry; a film thickness sensor 11; and a sprocket hole monitor 12. The monitor 12 has four probes 12 (a-d) urged towards associated electromagnets 13 (a-d), but normally out of contact therewith. An enlarged or torn sprocket hole permits at least one of the probes, which are transversely spread, to contact its associated electromagnet, thereby giving a first signal to the brake circuitry to stop the film drive. The sensor 11 is provided with two spaced electrical contact studs (49, 46) Fig.3  (not shown) and a projection (44) bearing against an edge portion of the film in the guide. Thicker film than normal will raise the projection (44) bringing the studs (49, 46) into contact and giving a second signal to the brake circuitry to stop the film drive. Indicator circuitry Fig. 5 (not shown) also receives both signals so as to provide an audible and/or visual fault indication in response to the detection of either signal. When an operator has dealt with the fault detected, he restarts the apparatus. After all the film has been checked, the film is rewound on to the supply spool 2, the electromagnets 13 (a-d) being de-energized so that the probes 12 (a-d) do not contact the film. A second sprocket hole monitor may be provided adjacent the opposite edge of the guide for film having two rows of perforations.

Abstract: 1289813 Navigation computers BUTLER NATIONAL CORP 7 Jan 1970 [7 Jan 1969] 847/70 Heading G4G A navigation system for a craft includes a way point computer on the craft which is responsive to radiant energy signals to provide first and second signals indicative of the coordinates of the craft with respect to the way point; first and second differentiating means respectively receiving the first and second signals and producing velocity signals with respect to the two co-ordinates; and means combining the outputs of the two differentiating means for producing a signal indicative of the craft's velocity relative to the way point. As shown, for an aircraft, the omni-bearing resolver 11 produces outputs proportional to the X and Y co-ordinates of the aircraft relative to the position of a DME and VOR station. The distance and bearing of the selected way point from the station is set into the system by manual adjustment of the distance potentiometer 16 and bearing resolver 21, the summing amplifiers 26 and 27 providing the X and Y co-ordinates of the way point relative to the aircraft. The coordinate system may be rotated through a desired angle by manual adjustment of a shaft 30 which controls a track resolver 31 and the stator 58 of a further resolver 56. The X and Y co-ordinate signals from resolver 31 are applied to motor 32 to indicate, by the point of intersection of pins 33 and 36, the position of the way point relative to the aircraft 54 which, in fact but not as shown, is mounted at the centre of meter 32; the co-ordinate signals are also differentiated at 39 and 44 to provide at point A a signal proportional to the groundspeed of the aircraft. This signal is applied to an indicator 48 and to a phase discriminator 49, the signal from which is applied to a motor 52'controlling the rotor 57 of resolver 56, from which a feedback signal is applied to the phase discriminator 49, whereby the aircraft symbol 54 mounted at the centre of motor 32 on the shaft 53 is rotated to maintain the phase discriminator output at zero. If resolver 31 is set to zero degrees, meter 32 will indicate the track made good relative to magnetic north. If the ground speed drops below a predetermined value, e.g. as with a hovering helicopter, relay 65 causes switch 60 to disconnect the phase discriminator 49 and to replace it with the power supply 70, whereby the aircraft symbol 54 is continuously rotated.

Abstract: 1297703 Reciprocating pumps for maintaining lubricant level in IC engine crank-cases R E NELSON 27 Feb 1970 [9 July 1969] 9605/70 Headings F1A and F1B [Also in Divisions G1 and H3] The level 16 of lubricant in an I.C. engine crank-case 15 is maintained at a predetermined level by an electrically operated pump 10 which ceases to pump lubricant from a reservoir 12 into the crank-case when a dip-tube 26 is covered by the lubricant. The pump comprises a piston 51 reciprocable in a cylinder 36, thereby to draw lubricant in a chamber 42 past an inlet valve 62 and deliver it past a spring urged ring valve 55 into a chamber 40 having an outlet 43 to the crankcase. The chamber 40 is bounded on one side by a diaphragm 31 reciprocated with the piston 51. When the dip tube becomes submerged air is trapped in the chamber 40 preventing movement of the diaphragm and piston. The piston is reciprocated by a solenoid 71 energized by a pulsed electric supply produced in an A.C. or D.C. energized oscillator circuit, (See Divisions H3-5). A core 76 fixed to the piston is moved by the solenoid through either the suction or delivery stroke, the other stroke being effected by a spring. A further or alternative dip tube may lead to the chamber on the other side of the diaphragm 31, in which case the solenoid is disposed in sealed chamber, Figs.3, 4, 10 and 11 (not shown).
