Title: Apparatus for measuring the volumetric flow of a liquid
IPC: G01F15/08
Filed: 1965-09-07
Abstract: 1,116,184. De-gassing apparatus. PIERRE GUERIN S.A. 7 Sept., 1965 [2 Nov., 1964], No. 38183/65. Heading B1M. [Also in Division G1] A separator for separating air from a liquid being pumped through a volumetric flow gauge (not shown) comprises a body 11 having an inlet pipe 5 feeding tangentially into an annular channel 13 with perforated distributing partitions 14, 12 a float 19 being contained within the body 11, the float carrying a cylindrical tube 20 sliding in a bush 22, and having apertures 21 which allow escape of air from the body 11 when the float is in its lowermost position, as shown, a casing part 18 of the float, with the float in this position obturating apertures 17 leading to the liquid outlet pipe 7 of the separator. As liquid is pumped into the body 11 via the pipe 5, the float 19 rises allowing the liquid to escape through the apertures 17. This rise of the float 19 also obturates the apertures 21 so that the air pressure in the body 11 helps to pump the liquid out through the pipe 7. Upward movement of the pipe 20 also actuates a pivoted lever 29 to open a normally closed switch 28 to close an air escape valve 27 in a pipe 26. This valve is open when the apertures 21 are in communication with the interior of the body 11 to allow ready escape of air. Thus if only air entering via the pipe 5 the float will fall and the apertures will be obturated the air escaping through the pipe 26 and no air entering the liquid outlet pipe 7. A weighted pivoted lever 36 is also provided and this is actuated by a trip device 41 on the tube 20 which only actuates the lever on downward movement of the tube 20. This lever controls a switch 35 to open a valve 33 in a pipe 32 supplying compressed air to the interior of the body 11. This ensures that when the back pressure in the pipe 7 is greater than the pressure in the inlet pipe 5, the compressed air will force the liquid out of the pipe 7 until the apertures 17 become obturated as before.

A cable has soft aluminium phase conductors 1 surrounded by a casing 2 of a thermoplastic synthetic resin which is enclosed in a layer 3 of flexible material in which are embedded aluminium wires 5 and copper wires 6 forming the neutral conductor, the wires of the neutral conductor being applied with their direction of lay being reversed periodically along the cable. This is surrounded by a helical metal band 7 to ensure a uniform distribution of current between the wires 5, 6 and a casing 4 of a thermoplastic synthetic resin, e.g. polyvinyl chloride, is formed around the cable. The aluminium and copper wires, 5, 6 may be tinned and the sum of the cross-sections of all the copper wires may be greater than the cross-section of a fuse protecting the cable. The neutral conductor wires may alternatively each be formed by a copper wire sheathed in aluminium, the aluminium sheath being either pressed on to the copper wire by means of an extruder or shaped around the copper wire as a longitudinal strip the edges of which are welded together after this shaping. The neutral conductor wires may alternatively each be formed by an aluminium wire sheathed in copper, the copper sheath being applied by electrolytic means or by a copper strip shaped longitudinally around the aluminium wire, the strip edges being welded together by electric arc welding using a protective gas. Instead of using aluminium in the neutral conductor iron, iron alloys, or ferrous metals in general may be used. The phase conductors 1 may consist of aluminium wires pressed into the form of segment-shaped conductors.

Title: Fuel supply system for ram jet engine
Inventor: GREENLAND LEONARD SIDNEY
IPC: F02K7/10
Filed: 1959-11-17
Abstract: 918,244. Fluid-pressure servomotor control systems. HOBSON Ltd., H. M. Nov. 2, 1960 [Nov. 17, 1959], No. 39008/59. Addition to 884,509. Class 135. [Also in Group XXVI] The conditions for balance in the first and second pressure operated devices 12, 24 of the main invention involve the factor K which, for low Mach numbers is variable, and an improvement of the present invention consists in replacing the pressure KPC supplied to the devices by a fixed reference pressure, e.g. the fuel tank pressure PTK. A further improvement prevents instability arising in the system due to inertia of the air-driven fuel pump and consists in a pressure feedback unit arranged to counteract the change in air input pressure to the pump occasioned by response of the first pressure-operated device 12 to changes in PC. As shown, the first pressure-operated device 12<SP>1</SP> includes three diaphragms D 1 , D 2 , D 3  and an evacuated bellows B subjected to pressures PTK, PP, P3 and Pc. If A 1 , A 2 , A 3 , A B  represent, respectively, the areas of the diaphragms and bellows and A 1 =A 3 =A B , then for balance Similarly the second pressure-operated device 24<SP>1</SP> includes three diaphragms D 4 , D 5 , D 6  and an evacuated bellows B<SP>1</SP>, the condition for balance being The device 12<SP>1</SP> acts similarly to the device 12 of the main invention, an increase in Pc causing rod 15<SP>1</SP> to move upwards and cause counterclockwise movement of the lever 16<SP>1</SP> whereby the area of the servo-orifice 17<SP>1</SP> is increased. The increased flow past restrictor 19 causes a drop in the pressure P F  so that the diaphragm 7 moves to the left and increases the air pressure P F4  in the intake channel 8 of the fuel pump 1. Owing to the inertia of the pump there is a delay between the rise in pressure P F4  and the consequent rise in the pilot burner fuel pressure P p  whereby the orifice 17<SP>1</SP> opens too much which would cause the system to overshoot. To prevent this the pressure P F4  is supplied to both sides of a diaphragm 52 of the feedback unit 50 having a servo-orifice 51 in parallel with the orifice 17<SP>1</SP>. An increase in P F4  initially causes flow through a restrictor 53, thereby delaying the application of the full rise in pressure to the lower surface of the diaphragm 52 and the flow through orifice 51 is reduced by tilting of the arm 54. The size of the restrictor 53 is such that the value of P F4  is held down until P p  has reached the required value for this value of P F4 , the diaphragm 52 eventually returning to its balanced position.

Title: Apparatus for Inspecting and Sorting Comestible and Other Objects.
IPC: B07C5/342
Filed: 1967-08-24
Abstract: 1,172,751. Sorting objects by colour. MANDREL INDUSTRIES Inc. Aug. 24, 1967 [Aug. 24, 1966], No.39121/67. Heading G1A. In an arrangement for developing a rejection signal in respect of an object which is viewed to determine whether a selected characteristic is up to a desired standard, the presence of the object in the viewing zone is detected to permit a rejection signal if existent to be used at a sorting station and to effect normalization of the photo-electric viewing apparatus as the object leaves the zone. Potatoes are pumped with a fluid to pass singly and separately through an instruction station comprising a transparent tube 42 Fig. 3, through a head 41 having an odd number of photo-multipliers 57 looking along diameters into the tube from a surrounding cylindrical wall 43. The potatoes are illuminated by a ring of lamps 47 and an outer sleeve 46 containing fluid is provided around the tube so that a potato in contact with the inner tube wall will have the same appearance. A card or plate 49 having a predetermined colour is mounted on the inner wall of housing 43 opposite each viewer to serve as an optical standard against which the colour and reflectance of each potato may be determined, a darker colour being arranged to produce a bigger output. In the absence of a potato, the photomultiplier output is set or normalized by a D. C. feedback circuit and the feedback signal is maintained by a capacitor when the arrival of a potato is detected by a further longitudinally-spaced pair of photo-cells so that an output from the photo-multipliers is developed only if the colour differs from reference plate 49, and irrespective of the condition of the intervening fluid. The further pair of photo-cells serve also to measure the length of a potato, and the ejecting compressed air blast is controlled accordingly, i. e. one of two delay times for a short or long potato is selected and the blast time adjusted. Separate jets may be selectively operated. The rejected potatoes are deflected sideways beyond a separating wall for conveyance to a reject bin. Electromagnetically controlled compressed air jets are described with reference to Figs. 9 and 10 (not shown).

In a block data transmission system in which each block is preceded by a synchronizing signal, the synchronizing signal is distinguished from the data by a different form of modulation. If the data block includes error-correcting signals these may also be distinguished in a similar manner. Several forms of modulation are referred to. In one example, Fig. 1, which employs binary pulse width modulation, the zero bits of the synchronizing signals are highly attenuated. In another, Fig. 3, the data and synchronizing bits are transmitted by frequency shift, and in addition the bits are amplitude modulated. The synchronizing signal in an error-correcting system may be modulated to indicate the correct reception of a block.
