Filed: 1971-05-24
Abstract: 1284060 Volume-compensating devices INDUSTRIE PIRELLI SpA 24 May 1971 [23 May 1970] 16686/71 Heading F1P A volume-compensation apparatus 10 for oilfilled electric power cables comprises a pressure tank 12 divided into two completely oil-filled chambers 14, 16 by a bellows 20 and end-plate 28. Chamber 14 communicates through a port 22 with the cable and chamber 16 communicates through port 22a with a chamber 24 which receives oil expelled from chamber 16. Valve means 26, 26a serve to close ports 22, 22a when the volume of chamber 14 reaches a predetermined minimum and maximum respectively, thus preventing an excess pressure differential across the bellows. Valve means 26 has a plunger 46 biased away from a closure member 56 by spring 64, member 56 being biased from the base of valve body 48 by spring 60. Valve means 26a is identical. When the volume of chamber 14 reaches a minimum, end-plate 28 engages plunger 46 to close port 22. If seating is not complete plunger 46 moves on downwards to seal a part 68 thereof against a valve seat 66. When chamber 14 attains a maximum volume plate 28 engages plunger 46a to close port 22a. Chamber 24 is connected to a gas pressure vessel 38. There is also described an embodiment in which chamber 24 and vessel 38 are combined, Fig.2 (not shown).
Patent GB-733361-A (GB)
Title: Manufacture of new trisazo-dyestuffs
IPC: C09B31/28
Filed: 1952-07-02
Abstract: The invention comprises trisazo dyestuffs of the formula <FORM:0733361/IV (c)/1> where R1 is a salicylic acid residue (which may be further substituted) and R2 is a p-phenylene residue carrying an alkoxy group of 1-3 carbon atoms ortho to the azo linkage joining it to the naphthalene nucleus.  These are made by coupling diazotized aminoazo compounds R1-N = N-R2-NH2 with N - (4 - amino-3-sulphophenyl)-J acid, diazotizing the product and coupling with 8-oxyquinoline.  The monoazo intermediates are obtained (1) by coupling a salicylic acid with a diazotized m-alkoxyaniline carrying in the p-position a substituent convertible to amino (e.g. nitro, acylamino) and then so converting, or (2) from a diazotized aminosalicylic acid and a p-coupling, o-alkoxyaniline.  The trisazo dyestuffs give navy blue dyeings or prints on wool, silk, leather, cotton, linen and regenerated cellulose.  They may be metallized in the dyebath or on the fibre, e.g. by the methods of Specifications 455,274 and 619,969.  The preparation of the dyestuff 2-methyl - 4 - amino - 5 - methoxy - 41 - oxyazobenzene - 31 - carboxylic acid --> N - (4-amino - 3 - sulphophenyl) - J acid --> 8-oxyquinoline is exemplified, together with the dyeing of cotton therewith (coppered in the dyebath).  Additional aminoazo intermediates specified are 2 : 5-dimethoxy-4-amino-41-oxyazobenzene - 31 - carboxylic acid, 2 - methyl-5 - methoxy - 51 - chloro - 41 - oxyazobenzene-31 - carboxylic acid and 4 - amino - 3 - methoxy-41 - oxyazobenzene - 31 - carboxylic acid.  Other suitable components for the aminoazo intermediates are mentioned.

Title: Improvements in or relating to electric circuits empolying piezoresistive materials
IPC: A01D78/00
Filed: 1960-05-12
Abstract: 950,937. Piezo-resistive elements. WESTERN ELECTRIC CO. Inc. May 12, 1960 [May 19, 1959], No. 16758/60. Heading H1K. [Also in Division G1] A circuit for a mechanical strain transducer comprises an input circuit including a source of electrical energy; at least one piezo-resistive element the resistance of which is varied as it is subjected to mechanical strain; and an output circuit including an indicating device and a temperature sensitive resistance which compensates at least in part for unwanted variations of sensitivity with temperature of the piezoresistive element. Two elements, Fig. 1 (not shown), or four elements 21-24, Fig. 2, of piezo-resistive material, are cemented to a resilient strip 13 of, e.g., steel, phosphor bronze or " elinvar," from which the elements are insulated, or of insulating material such as polystyrene, strip 13 being held in a rigid support 10. The elements are connected as shown into a Wheatstone bridge arrangement supplied by an input circuit containing an electrical energy source 17 and a relatively high resistance 16 to provide a " constant current " source. The bridge feeds into an output circuit comprising a meter 19 and a shunt resistor 18 the resistance of which so varies with temperature as to provide the desired compensation. The resistance 16 may also be such as to share in this compensation. A force 26 exerted perpendicularly to the elements places elements 21, 22 under tension and elements 23, 24 under compression; and a signal, amplified by this differential effect, gives a reading on the meter 19. In the two element embodiment the other bridge arms are adjustable resistances. The resistor 18 may be of, say, Ni, Al, Cu, or Zn; or. of molybdenum disulphide for use at higher temperatures. Power loss may be reduced by making the resistor 16 of C or Ti. In another embodiment, Fig. 3, two piezo-resistive elements supported on a frame 50 form the four arms of the bridge. Each element comprises a central mass, 52 or 54, and two equal legs 21<SP>11</SP>, 23<SP>11</SP>, or 22<SP>11</SP>, 24<SP>11</SP>, cut from a single crystal. The piezoresistive elements may be of, say, silicon, germanium, indium antimonide, gallium arsenide, silicon carbide, aluminium antimonide, aluminium arsenide, aluminium phosphide, gallium antimonide, gallium phosphide or indium arsenide, and may be doped, e.g. with boron, phosphorus, or zinc. They may be cut from single crystals; and the amount of compensation needed may be reduced by using material of which the resistance is relatively stable with temperature variation; e.g. silicon containing substantially 10<SP>19</SP> atoms per c.c. of boron or phosphorus, or even from 3 10<SP>18</SP> to 5 x 10<SP>19</SP> atoms per c.c. of boron or phosphorus. Specification 940,730 is referred to.

Title: Improvements in and connected with oil fuel pumps for internal combustion engines
IPC: F02M59/38
Filed: 1925-06-30
Abstract: 258,682. E. L.-S. Engines, Ltd., and Spina, E. Lanzerotti-. June 30, 1025. Single-acting piston pumps; regulating delivery by closing and opening suction valves; valves, arrangement of.-A fuel pump for internal-combustion engines comprises a plunger 1 reciprocating within a ported sleeve 2, which is engaged by the plunger during its delivery stroke, and is adjustable relatively to the plunger. During the suction stroke, liquid enters the vessel from the inlet 22 through a port 5 in an outer sleeve 3, a port 6<1> in the sleeve 2, and a port 6 and axial passage in the plunger. During the suction stroke the sleeve 2 is moved by a spring 13 in the same direction as the plunger, and when the ports 6<1>, 6 are closed by the port 3, liquid continues to enter the barrel through a port 7 in the sleeve 2. During the first part of the delivery stroke, liquid returns to the inlet 22 through the port 7 until the plunger engages the end of the sleeve 2 and closes the port 7. The plunger and sleeve then travel together and the liquid is delivered through the outlet valve 8 until the ports 6, 6<1> register with the port 5, after which the remaining liquid is returned to the inlet through the axial duct in the plunger. The travel of the sleeve 2 is limited by a screwthreaded stop 15 which engages a shoulder 14 on the sleeve. The stop may be adjusted by a slotted rod 16 engaging a pin 17 on the sleeve to vary the moment at which the plunger closes the port 7 and thus vary the moment at which delivery begins. The quantity delivered may be varied by adjusting the sleeve 3 axially by means of a crank-pin 11 and lever 18; or the sleeve may be angularly adjusted, in which case, the port 5 would be of helical form.

Abstract: 924,122. Automatic pressure control. BOUELLAT ENGINEERING Ltd. May 27, 1959 [May 27, 1958], No. 16951/58. Class 38 (4). [Also in Group XIII] Nitrogen from a cylinder 13 passes into a steam and water drum 5 of a steam pressurized hot water system when a valve 20 is opened by a solenoid controlled by a diaphragm device 11 responding to a drop in drum pressure. The system may be used for heating by circulating the hot water or for providing a draw-off supply. When the drum pressure is sufficient, the valve 20 may be closed by the device 11 or by a similar device 12. On shut-down of the system, the admission of nitrogen may be through the valve 20 or through a hand-operated valve 19. The drum 5 and its supply boilers or boiler 1 have safety valves 2, 9 and the drum has a float-operated high-level alarm 8 and a take-off pipe 10. The automatic admission of nitrogen occurs when the pressure drops in operation or on shut-down, but there may be an arrangement for the admission at one only of these events. In Fig. 1 (not shown), there is indicated an open tank connected to a pump for feeding to the bottom of the drum 5. In Fig. 2 there is shown an expansion vessel 22 which is provided when the drum 5 is unable to take up all the expansion and which is given a light charge of nitrogen through a hand valve 24 and has a hand makeup valve 26. In the drum 5, a float 29 near the bottom controls a feed pump 23 through which the vessel 22 is connected to the boiler 1. Other connections between the vessel and boiler are through a hand valve 32 and a solenoid-operated spill valve 33 controlled by a float 34 in the drum 5.

Abstract: 700,717. Starting direct-injection engines. DAIMLER-BENZ AKT.-GES. July 18, 1951 [July 18, 1950], No. 17107/51. Class 7(3) A stop 30 setting the normal maximum supply position of a fuel pump regulator 17 is connected by a cable 44 to the throttle valve actuating mechanism so that it is moved, when the throttle valve is closed, to allow the regulator to move to an excess supply position for starting, in which position the regulator remains, even if the throttle valve is subsequently reopened, until the engine has started. As shown, the regulator 17 controlling the pump control rod 15 comprises a suctiontype governor, the travel of which in the increased supply direction is limited by engagement of a part 18 thereof with a stop lever 28 held in the maximum supply position by the stop 30 engaging a pin 29 thereon. As the throttle valve is closed, lost motion occurs between the cable 44 and a spring-loaded sleeve 36 carrying the stop 30 until, just before the fully closed position, the end 45 of cable 44 engages the end of the sleeve 36 and the stop 30 is raised, allowing the lever 28 to move back until arrested by a stop 49, whereby the regulating mechanism is allowed to move to an excess fuel supply position, after the engine has stopped, in order to facilitate subsequent restarting. Due to the lost motion between the cable 44 and sleeve 36 the throttle valve may be reopened while the regulating mechanism remains held in the excess supply position by the governor spring 24 until the engine is started. The lever 28 is rotatable by a lever 33 to move the regulator 17 to a fuel cut-off position to stop the engine. The sleeve 36 is guided in a sleeve 37 to which is attached a metal tube 46 enclosing the cable 44. The stop device is inserted as a unit and held in position by a screw 40 which is surrounded by a cap 51, the retaining screws of which are sealed to prevent tampering. The device is also applicable to a centrifugal governor.

[Also in Group XXX] Apparatus for jigging and conveying filled bags comprises in one form, Figs. 1 and 3, a base plate 21 which is mounted on leaf springs 21a and 21b and coupled by a rod 100 to an eccentric 21c driven by an electric motor 97. Side guide plates 105, 106, e.g., of plywood, are secured to rods 109 extending from brackets 22a which are attached to the side flanges 107 of the base plate. The rods are adjustable in sockets 108 and are secured by set screws 115. Each bag is suspended between the plates 105, 106 from a filling spout whose centre line is indicated at 117 and the motor 97 is energized to cause the plate 21 to oscillate in such manner that a point 118 thereon is moved in an arcuate path Oa. The vertical and horizontal components Ob and Oc of this motion cause the plates 105 and 106 to vibrate in sympathy about horizontal and vertical axes 122 and 120 whereby the plates operate on the bag with a slapping action to settle its contents during the filling operation. When the latter has been completed, the bag is released from the spout and falls on to the plate 21. The oscillatory motion of the latter moves the bag to the left on to a belt 119 which conveys it to sewing mechanism, the plates 105, 106 continuing to operate to consolidate its contents and shape it to a substantially square cross-section. In a modification, Figs. 4 and 5, side plates 22, 23 corresponding to the plates 105, 106 are tilted towards each other and are extended along either side of the belt 25 which conveys the bags through the sewing mechanism 28, their forward ends being supported by rubber members 50, 51. The mouth of each bag is engaged by inclined feed dogs 26a which urge it against a levelling guide 29 of inverted channel cross-section and is embraced by a closure tape 27 which is fed through a guide 48. Operation of the mechanism 28 is controlled by a micro-switch 42 operated by an arm 43 which is engaged by the bag. The plates 105, 106 or 22, 23 may be mounted on the frame of the apparatus and actuated by separate vibrators. Belgian Specification 539,616 and French Specification 1,134,056 are referred to.
