Title: Improvements in predetermining devices of fluid measuring and dispensing apparatus
IPC: B67D7/08
Filed: 1945-03-20
Abstract: 600,269. Dispensing liquids. S.A.T.A.M. SOC. ANON. POUR TOUS APPAREILLAGES MECANIQUES. March 20, 1945, No. 6934. Convention date, Oct. 12, 1943. [Class 116] [Also in Group XIX] The invention relates to a device which is set to determine the amount of fluid subsequently to be delivered by a fluiddispensing apparatus. The device comprises a first set of three numeral drums 11, 13, 15 which are set to indicate the cost of the fluid, and a second set of drums 10, 12, 14 which show the corresponding volume. Each drum of the first set is set by a respective setting device 203, 202, 201 each connected to its drum by the planet pinion 45 of a respective differential gear, one sun wheel 25 of which is connected to the numeral drum, the other sun wheel 35 being driven from the next lower drum by gearing 65, 85 and transfer mechanism 93, 113. In the case of the lowest cost drum 11, the said sun wheel is driven through gearing 131, 61 from the fluid-delivery meter to turn all the cost drums backwards to zero from the posi, tion into which they have been set by the setting devices 203, 202, 201. The volumeindicating drums 10, 12, 14 are preset at the same time as the cost drums by connections 105, 104, 74. The lowest volumeindicating drum is also driven through gearing 130, 60 from the pump. Differential gearing is also incorporated in the drive to these drums as shown. When all the cost or volume-indicating drums have been turned back to zero by the pump the teeth 125, 123, 121 or 124, 122, 120 of a comb 301 or 302 respectively co-operate with cams 55 secured to the drums to stop delivery. The setting devices are locked, by means not shown, when fluid is being delivered. The first set of drums 11, 13, 15 may be obscured by a shutter (not shown) when desired.

IPC: D06M10/02
Filed: 1955-03-09
Abstract: <PICT:0834403/IV(c)/1> <PICT:0834403/IV(c)/2> Hides, fabrics, fibrous materials and the like immersed in a liquid are treated with ultrasonic irradiation by producing cavitation conditions in the liquid by paddles moving at high speed (preferably 100-250 m.p.h.) relative to the material at a small separation (preferably 0.5 inch) from it, in order to produce cavitation bubbles which collapse in contact with the material.  In Fig. 1 hides 14 are held to the drum 11 by wire mesh grids 15 and a surrounding drum 12 carrying paddles 28 is rotated in relation to drum 11 in liquid in a vessel, not shown.  Fig. 2 provides for the treatment of material 16 which is wound from supply reel 17 to take-up reel 18 through guide-rollers 19, 21 separated by a fairing 22.  The paddles 30 are set at an angle to divert the cavitation pockets towards the material, which action may be assisted by a liquid flow through the material.  If the material to be treated is fibrous it may be held (Fig. 3, not shown), between retaining meshed belts and passed linearly through an elongated tank while the adjacent paddles are carried by two endless belts.  The paddles may be of quadrilateral cross-section set at rightangles to the direction of motion, as shown at 28 in Fig. 1, or inclined as shown at 30 in Fig. 2.  More elaborate constructions are shown in Fig. 4 (not shown), designed to allow liquid to flow between the paddles to impart a strong transverse vibration thereto when the apparatus is operating.

Title: Improvements in or relating to alternating current watt meters and watt meter relays
IPC: G01R11/52
Filed: 1937-03-09
Abstract: 495,253. Power meters. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 9, 1937, No. 6946. Convention date, March 10, 1936. [Class 37] In an electrodynamometer wattmeter measuring reactive power, the parasitic couple resulting from the action of the current circuit or circuits on the current or currents produced in the voltage circuit or circuits by mutual induction, is cancelled by arranging the voltage winding so that any such parasitic current is split into a number of opposing currents which substantially cancel one another out. As shown, Fig. 1, the voltage winding is divided into halves 2, 2<1>, connected in series, respectively, with a capacitance 3 and inductance 4 so arranged that the parasitic currents produced in the voltage windings 2, 2<1> are of opposite polarity and equal magnitude and therefore no parasitic couple results. The driving currents in windings 2, 2<1> are however additive and the couple produced thereby in conjunction with the current winding 1, 1<1> is proportional to the reactive power. The Specification as open to inspection under Sect. 91 states that wattmeters sensitive to active or complex power may be connected in a similar manner. Thus, in one arrangement, a correcting arrangement as in Fig. 1 is provided having in addition a series connected reactance which it is stated may be so dimensioned as to render the wattmeter sensitive to active or complex power. In Fig. 3 (Cancelled), this reactance is shown at 5. The voltage coils 2, 2<1> are electrically independent but mechanically rigid, the two parasitic couples acting thereon cancelling each other out. This subject-matter does not appear in the Specification as accepted.

Abstract: 868,408. Tail assemblies for self-propelled missiles. HOTCHKISS-BRANDT. Feb. 29, 1960 [March 9, 1959], No. 6984/60. Classes 9(1) and 9(2). A fin-stabilized self-propelled missile is provided having fins arranged on transverse pivots and maintained in a collapsed state prior to launching, deployment of the fins being produced by the pressure of the propellent gases. According to the invention the fins A are mounted on a support 1 screwed into the rear of the rocket casing C and having an axial bore in which the Venturi nozzle T is slidable, the nozzle exterior being shaped to provide bearing surfaces for parts of the fins, such that before launching the fins maintain the nozzle in its forward position and after launching the nozzle is thrust rearwardly by the gases and forces the fins to rotate about their pivots 13. The support 1 is counterbored to house a seal 9 around the nozzle and heat-insulating material 10 shielding the support from the propellant D. Radially arranged slots 4 in the support receive the forward ends of the fins of which the pivots 13 are housed in blind bores 5, Fig. 6. Each fin A has a doubly-bevelled edge 14, which becomes the leading edge when the fins are deployed. A band B securing the fins in the collapsed position is forced off when the missile is placed in a launcher. Small vanes 12 inclined to the longitudinal axis of the missile may be placed in the nozzle to produce a rotary motion of the missile. The slots in the support may also be so arranged that, when deployed, the fins A give a spin to the missile.

Title: Improvements relating to releasing mechanism for pre-payment meters
IPC: G07F15/06
Filed: 1927-03-14
Abstract: 267,926. Allgemeine Elektricitõts- Ges. March 19, 1926, [Convention date]. Electricity, supplying by meter.-Relates to a meter in which the switch-releasing mechanism comprises a catch lever co-operating with a prepayment spindle in the form of a half-cylinder, which is rotated in one direction by prepayment and in the reverse direction by the consumption and by an additional turning moment independent of the consumption but corresponding to the amount of a fixed charge. According to the invention, the catch lever is controlled indirectly by the half-cylinder through an intermediate locking lever. A catch lever b, Fig. 1, controlling the switch mechanism is held in switch closing position by a lever d which is held down against a stop f by a spring e. The half-cylinder a rotating in the direction of the arrow under the action of the meter raises the lever d so that the lever b is pulled by a spring c against a stop g to break the circuit. The half-cylinder a continues to rotate under the action of the additional turning moment. When the amount of the fixed charge is paid the lever d re-assumes its position against the stop f, and after the insertion of additional coins, the lever b is re-set and completes the circuit. The Specification as open to inspection under Sect. 91 (3) (a) describes a switch-mechanism comprising a switch roller m, Fig. 1 (Cancelled), of insulating material which has an arm k pressed by a strong spiral spring against a short arm on the catch lever b. The catch lever holds the roller so that the circuit is made by contact springs o resting against a contact part n. This subject-matter does not appear in the Specification as accepted.

Title: Process for solvent refining lubricating oils
IPC: C10G53/06
Filed: 1964-02-21
Abstract: A process for solvent refining lubricating oils comprises concurrently solvent refining at least two hydrocarbon lubricating oil fractions of different viscosities with a solvent effective preferentially to dissolve aromatic hydrocarbon components, for example furfural, in separate treating zones, separating the extract and raffinate phases from each zone, combining the raffinates and separating the solvent from the combined raffinates, solvent dewaxing the combined raffinate with a solvent effective preferentially to dissolve the oily components of said combined raffinate, for example a mixture of methyl ethyl ketone with benzene or toluene, under conditions effective to precipitate waxy components, separating the precipitated wax and separating dewaxing solvent from the dewaxed oil.  The extracts may be combined, and the solvent recovered.  The two starting fractions may be obtained by fractionating a hydrocarbon oil, solvent deasphalting the residual fraction, for example with propane, separating the precipitated asphalt from the solvent and deasphalted oil, and separating the solvent.  The dewaxed oil may be subjected to a finishing treatment to improve the colour and carbon residue, and may then be fractionated to give lubricating oils of differing viscosities. Suitable finishing treatments include hydrofinishing, acid treatment and clay filtration, e.g. with fuller's earth, bauxite or "Filtrol" (Registered Trade Mark).

Abstract: 1139561 Seat adjustments FICHTEL & SACHS A G 22 Feb 1966 [25 Feb 1965 16 July 1965] 7642/66 Index F2S 31 [Also in Division B8] Fig.1 shows a hydropneumatic device for vertical movement, particularly in steplessly adjustable tables and seats, comprises a receptacle 1 with a piston 2 movable therein and connected to a piston rod 3 by a screwthread 30. A valve member 6 in the form of a resilient washer is secured to an extension 31 of the piston rod 3. The piston 2 has a liquid communication passage 4 which can be closed by the valve member 6 by rotation of the piston rod 3, using a control lever 13. The receptacle 1 is filled by a liquid and a gas, the gas in chamber 20 being separated from the liquid in chambers 18, 19 by a separating piston 14. The device is extended by opening the passage 4, the pressure of the gas forcing liquid from the chamber 19 into the chamber 18. The device is contracted by pushing the piston rod 3 into the receptacle 1 by hand, the passage 4 being open, overcoming the opposing pressure of the gas in the chamber 20. The piston rod 3 can be locked in any intermediate position by using the valve member 6 to close the passage 4. Fig.2 (not shown) illustrates a modification in which a spring loaded valve member (106) is operated by a knob (111). Fig.3 shows a modification wherein a cylinder 301 is sealed at the top and divided into two chambers 318, 319 by a piston 303 with piston rod 304. Liquid fills chamber 319, the chamber 318 containing liquid and gas. A valve member 306 controls passage of liquid between the chambers 318, 319. A washer 309 loaded by a spring 312 acts as a throttle valve with valve seat 334 when liquid flown from chamber 319 to 318 as the rod 304 moves outwards, but disengages from the valve seat 334 so as not to inhibit liquid flowing from chamber 318 to chamber 319 as the rod 304 moves inwards.
