Title: Nuclear reactor fuelling machine
IPC: G21C19/12
Filed: 1969-04-14
Abstract: 1,260,682. Fuelling reactors. ATOMIC ENERGY OF CANADA Ltd. 14 April, 1969 [15 April, 1968], No. 18963/69. Heading G6C. A pressurized water reactor C has fuel channels D which are refuelled by a machine A, this machine comprising a main carriage 10 having wheels 12 and supporting a trolley 11 having wheels 17. Two columns 20 on the trolley 11 support a transverse member N for vertical sliding movement, a fuelling machine head L having a snout-assembly P being mounted on the member N so as to be rotatable about a horizontal axis. Thus the snout-assembly P may be coupled to a selected channel D as shown in Fig. 1 by appropriate horizontal movement of the carriage 10 and trolley 11 and vertical movement of the member N. To connect the snoutassembly P to horizontal fuel supply tubes (not shown) extending through the vault B the head L is rotated through 90 degrees about the horizontal axis. The machine head L, Fig. 2, comprises a main housing 100 having a space 115, which, when the machine is connected to a channel D and a valve 108 is opened, is subjected to the reactor pressure. Below the space 115 is a turret 102 mounted on a bearing 101 and driven by a motor 105 and gearing 103, 104. A hydrostatic seal 116 seals the turret 102 against the space 115. The turret has two ram barrels 121 and two fuel barrels 122. Each barrel 121 contains a ram Q and each barrel 122 contains a piston 160. The upper end of the barrel 122 is open to the space 115 and the lower end (Fig. 4, not shown) is closed and connected to a pressurized water supply whereby the piston 160 may be moved up and down the barrel as required by the pressure difference between the space and the water supply. A tape 166 connected to the piston 160 winds on and off a spring-biased pulley (Figs. 4-6, not shown) which keeps the tape taut and gives an indication of the position of the piston within the barrel 122 by means of a potentiometer driven by the pulley. Operation.-Each channel D contains a fuel element string connected at its lower end to a plug unit by a T-pin. The T-pin is carried by the upper end of the plug unit and is similar to the T-pin 162 mounted in the piston 160. To empty a channel D a barrel 121 is aligned therewith and the ram Q is advanced to unlock the plug unit from the channel. The ram Q is withdrawn and the fuel element string and plug unit are lowered until the T-pin on the plug unit is level with the extreme end 270 of the barrel 121. The fuel element string is locked against longitudinal movement by means not shown. The turret 102 is rotated through 90 degrees to disengage the T-pin of the plug unit from the fuel element string and to engage the T-pin 162 with the string. The fuel element string is unlocked and the pressure beneath the piston 160 is reduced to lower the string into the barrel 122. A new fuel element string is introduced into the channel D by a reverse procedure.

Title: Process for the production of pigments from cashewshell liquid or its constituents and derivatives
IPC: C09B61/00
Filed: 1944-10-04
Abstract: A pigment is obtained from cashew-shell liquid or its constituents or its derivatives comprising anacardol, anacardic acid, anilides and naphthylamides of anacardic acid by treatment, e.g. in aqueous or alcoholic medium, with nitrous acid and a water-soluble metal salt. The treatment with nitrous acid and with the metal salt may be effected simultaneously or successively in that order with the intermediate isolation of a nitroso compound.  The nitrous acid is produced in situ by the action of a dilute acid on a nitrite. Specified salts are those of iron, cobalt, chromium, nickel, copper, manganese and vanadium.  In examples: (1) aqueous sodium nitrate is added to an emulsion of cashew-shell liquid in aqueous ferric chloride which produces a brilliant olive green pigment upon acidification with dilute, acetic or sulphuric acid; (2) aqueous sodium nitrite is added to an alcoholic solution of cashew-shell liquid and the solution is acidified with dilute sulphuric acid to obtain a yellowish green pigment; (3) aqueous sodium nitrite is added to an emulsion of cashew-shell liquid in an alcoholic solution of ferric chloride with subsequent acidification; (4) ferric chloride in dilute acid was added to an emulsion of aqueous sodium nitrite and cashew-shell liquid.  The pigments are soluble in oils and common organic solvents excepting alcohol and can be used for colouring hair oil, boot polish, paints, enamels, lacquers, distempers, varnishes and printing inks.  A sample was furnished under Sect. 2 (5) of a dye produced by treating cashewnut-shell liquid with ferric chloride and nitrous acid.

Title: Improvements in and relating to Machines for Forming Articles of Glass.
Inventor: MILLER WILLIAM JOSEPH
IPC: C03B9/195
Filed: 1918-08-08
Abstract: 130,985. Miller, W. J. Aug. 11, 1917, [Convention date]. Moulding under pressure.-Relates to a press for moulding glass articles. The plunger P, Fig. 1, is mounted on a movable cross-head N, connected with a fixed cross-head 126 by toggles 174, 176, which are operated through links 175 by a cross-head 172 moved up and down by fluid pressure acting in the cylinder J. The capacity of the cylinder J can be varied by moving a false bead or piston 133, Fig. 4, which is fixed to a screwed sleeve 132 passing through the true cylinder head 130. An extension 134 of the piston-rod 129 is grooved at 136 to allow fiuid pressure to pass from the supply-pipe 152, through the sleeve 132, into the space between the false head 133 and the piston 128, and so cause this to descend. The piston is raised by air admitted through a pipe 149. The last part of the upward movement of the piston 128 closes the entrance to the groove 136 and the imprisoned air is allowed to escape slowly through a small port 140, thus producing a cushioning effect. The height of the cylinder J, and of the cross-head 126 attached to it, is adjusted by screw collars 146, 148.

Title: Spool or bobbin having means for fastening a yarn end
IPC: B65H75/28
Filed: 1936-07-11
Abstract: 465,387. Bobbins. CLINTON, H. D. July 11, 1936, No. 19291. Convention date, Oct. 4, 1935. [Class 120 (iii)] A spool or bobbin comprises a barrel 7 with a disc like head 9, an annular plate 14 applied to the outer face of said head, said plate having an inner portion resting flat upon said head and a surrounding peripheral portion 14a raised from the head in an over-extending parallel relation thereto so as to form with said head an annular groove 15 extended beyond and coaxial with the barrel and means 14b formed in said plate providing a friction catch to engage a strand of yarn or thread wound in the said groove. Thus, the tail end of a winding may be held in a convenient position for securing to the lead end of the next bobbin to obtain a continuous feeding of yarn. The barrel 7 is preferably of wood with a bore or partial bore 8 for lightening and engagement with a pin or gudgeon. The heads 9 are preferably of hard vulcanized fibre, but may be of steel or of artificial mouldable material. A plug 10 with an enlarged head 10a fits through a centre opening in the head into a cavity 11 in the barrel 7. The head portion 10a may be surrounded with a metal ring 13 with a flange 13a, ribs 13c, and teeth 13d to help keep the plug in position. The plate 14 may be formed as an extension of an upper flange 13b on this ring 13. A washer 16 may be placed under the plate 14. A slot 17 in the head 9 leads radially towards the catch 14b. In a modification shown in Fig. 4, the plate member 14 is a separate member applied to the bobbin head and has a central raised portion 14c. This raised portion provides for a twister head attachment similar to that described in Specification 465,388. A slot 20 with a central bore enlargement is formed in the raised portion for fitting the driving lug of a twister spindle, portions of the plate surface opened to form this slot being turned inwards to provide sides for the slot. In Fig. 6, the catch 14b is not used, the end of the yarn 18 being held on the barrel and a loop therein is passed through slot 17, twisted and wrapped around the groove 14 until most of the slack is taken up, the ends of the loop then being drawn back through the slot 17 until the windings in groove 15 are tight. A few turns round the barrel over the end of yarn 18 then prevent slippage.

Abstract: 1426598 Motor vehicle suspensions DAIMLER-BENZ AG 24 April 1973 [24 April 1972] 19327/73 Heading B7D In a vehicle suspension comprising wheel carriers 10 located by lower and upper triangular guide members 11, 12, the upper guide members 12 are connected to the vehicle superstructure through cross-connecting means arranged such that when the guide members 12 are deflected equal amounts in the same direction during two-wheel bump they pivot about a common horizontal transverse axis w-w so that the wheels 22 move up and down parallel to the central longitudinal plane of the vehicle, whereas when the guide members 12 are deflected in opposite directions during roll they pivot about inclined axes y-y so that the wheels 22 assume parallel positions perpendicular to the road surface. The cross-connecting means includes a torsion bar 14 rotatably mounted on a frame member 19 by bearings 17, and a tubular member 13 rotatably mounted at its ends on the torsion bar 14 and connected at its centre to the torsion bar by splines 16. Each guide member 12 is connected to the torsion bar 14 by a connection C arranged so that deflection of the guide member twists the bar, and to the tubular member 13 by a connection D. During two-wheel bump the guide members 12, the tubular member 13 and the torsion bar 14 all rotate in unison about the axis w-w but during roll the tubular member 13 and the centre of the torsion bar 14 as the ends of the bar are twisted in opposite directions so that the guide member 12 pivot about the axes y-y defined by the connections C, D. The cross-connecting means may alternatively be associated with the lower guide members 11. The frame member 19 is supported on the superstructure together with differential gearing 23 by resilient mountings 20, 25 affording relatively soft location in the longitudinal direction. A track steering lever 15 rigidly attached to each wheel carrier 10 is connected to one end of a tracking control rod 30 the other end of which is connected to the tubular member 13 or is connected to a variable anchorage point, Figs. 14, 15 (not shown), the position of which is controlled in dependence on movements of the tubular member to obtain improved tracking. In a modification, Fig. 6 (not shown), each upper guide member is mounted at two spaced points on the tubular member and the end of the torsion bar is bent to form an arm connected by a generally vertical link to the guide member. In a front suspension, Fig. 11, the pivot axis of each lower guide member 411 is oblique or parallel to the longitudinal axis of the vehicle and the axis y-y is oblique. Steering mechanism is linked by tie rods 481 to steering arms 480 on the wheel carriers 410.

Title: Television method and arrangement
IPC: H04N5/60
Filed: 1934-06-30
Abstract: 444,881. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. June 30, 1934, No. 19361. Convention date, July 1, 1933. [Class 40 (v)] Television and telephone signals, transmitted on independent ultra-short carrier waves, are mixed at a receiver by a local oscillator 12 having a frequency between those of the vision and sound carriers, and are separated by a forked circuit 2. The oscillator is a screening - grid valve with reactive coupling through the internal capacities. The aerial 8 is coupled to the anode through an auto-transformer 10 and a small coupling condenser 11. The valve is adjusted to the lower bend of its anode - current characteristic by grid current through a resistance 14. According to a modification, Fig. 2 (not shown), the aerial is coupled inductively to the cathode circuit and the inner grid is earthed through a large condenser. The telephone signals are selected by a tuned circuit 18, 19 damped by a resistance 20 which also acts as a volume control. The television intermediate frequency is amplified by an amplifier 4 with screened coupling resistances 26, Fig. 3 (not shown). A choke 30 tuned to the highest side-band frequency is in series with the anode resistance 29. The amplifier is transformer coupled to a push-pull detector 36. Fading is compensated by a separate screening-grid valve 35, which also acts as an amplitude filter for separating the synchronizing signals.
