Title: Improvements in directional spray head
IPC: B05B11/04
Filed: 1962-04-13
Abstract: 994,843. Spray-producers. B. C. BRAINARD. April 13, 1962, No. 14438/62. Heading B2F, A spray device for forming a spray mixture of gas and liquid comprises a flexible container A adapted to be compressed to cause the air above the liquid in the container to flow up a passage 30 and along a transverse passage 40 so as to entrain liquid up a tube 29 and out through a discharge opening 36, said tube 29 terminating in a flat end 26 within the spray head 14. The cylindrical body 15 of the spray head 14 is sealed to a flange 13 extending from the bottle A. The spray head 14 fits under a cap 21 which is held in place on the body 10 of the bottle by flange and groove engagement 23, 24. A tube 27 up which liquid is forced when the flexible bottle A is squeezed fits in a socket 25 in the spray head, the flat end of the tube coinciding with the base of the socket. The gas passage 30 is generally wedge shaped, Fig. 3, and between its upper wall 32 and the flat end 26 of the tube 27 a transverse passage 40 is formed, approximating in width to half the bore 29 of the tube. The converging side walls 34 of the gas passage terminate in an imaginary line 35 which touches the bore 29 where it is nearest the chamber 30. The outlet passage 36, extending through the top of the spray head 14, has its inner wall 37 inclined, the angle of inclination being related to the extent to which the spray is to be combined. As shown, Fig. 2, the end 26 of the tube 27 is normal to its axis, but in a modification the flat end 26 is at an angle to the axis of the tube and directs the spray upwards, while in another modification it is at an angle to direct the spray downwards. In every case the point of maximum construction of the gas passage is opposite the outlet of the liquid-supply tube and gas is forced across the end of the tube. The relative sizes of the liquid or gas passages are discussed in the Specification.

Title: Low molecular weight acrylic polymers
IPC: C08F265/06
Filed: 1973-03-28
Abstract: 1431446 Low molecular acrylic ester polymers ROHM & HAAS CO 28 March 1973 [5 April 1972] 14886/73 Heading C3P Low molecular weight polymers of one or more esters of acrylic acid are prepared by polymerizing the ester(s) in the presence of an alkoxide as anionic catalyst, whereby the polymer produced has an average chain length of 6 to 30 mers. Suitable esters include those of the formula wherein R is alkyl, cycloalkyl, aminoalkyl, mono- or di-alkylaminoalkyl, heterocyclic-substituted alkyl, alkenyl (e.g. allyl), allyloxyalkyl, alkoxyalkyl, aryloxyalkyl and aralkyl; and also bisacrylate esters of diols. Polymerization is suitably effected by adding the monomer(s) gradually to a suspension or solution of the alkoxide in an inert solvent at a temperature of 20 to 125 C.; an alcohol may optionally be included as a chain regulating agent. The alkoxide catalyst is suitably an alkoxide of sodium or potassium, e.g. sodium methoxide, potassium methoxide or potassium t-butoxide. The ester polymers can be modified by hydrolysis to convert some or all of the ester groups to carboxylic acid (salt) groups. The acid polymers can further be reacted with ethylene or propylene oxide, hydroxyalkyl ester polymers, or with halogenating agents to produce in the latter case acid halide derivatives The ester polymers can also be modified by transesterification with an alcohol; where a polyol, e.g. diol, is used, the modified polymer contains free hydroxyl groups and can be further modified by reaction with a polyisocyanate to form a polyurethane. By virtue of the double bond present at the end of the polymer molecule, the ester polymers can also be copolymerized with other ethylenically unsaturated compounds. The ester polymers and their modified derivatives can be used in such applications as adhesives, plasticizers, levelling agents, meltindex improvers, impregnants, fillers, and in formulating coating compositions; they may be admixed with such components as plasticizers and carriers (diluents).

Abstract: 1419844 Fuel cells LICENTIA PATENTV-ERWALTUNGS GmbH 28 March 1973 [28 March 1972] 14932/73 Heading H1B In a fuel cell system having a circulating electrolyte and air cathodes the dilution of the electrolyte is maintained within a preselected range by increasing the operating temperature of the fuel cell if the dilection is sensed to be too high and decreasing the temperature if the sensed dilution is too low by controlling the electrolyte temperature. In the hydrogenoxygen (or air) system shown there is provided within a temperature insulating housing 1 a fuel cell 2 in which water is a reaction product and the circulating electrolyte is carried away through conduits 21, 22 to an electrolyte container 4 which houses an electrolyte temperature sensor 6 and level indicator 7 having upper and lower contacts 8, 9. If the electrolyte level 33 reaches the lower contact 9 then a signal from indicator 7 to switching element 25 causes twoway valve 3 to circulate the returning electrolyte through an external electrolyte cooler 16 before returning to the container 4. If the electrolyte level 33 reaches the upper contact 8 switching element 26 switches in an electrolyte heater 5 which is also influenced by the temperature senser 6 and by the output of voltage senser 29 across the battery connections 27, 28. The output from voltage sensor 29 also controls, through switch 30, the valve 13 for scavenging of the cells hydrogen chamber. The air pump 19 in the oxidant supply lino and thus the air supply to the cathodes is influenced through switch 31 responsive to the output of battery load current sensor 32. The output of air pump 19 and the variable minimum pressure of the pressure valve 15 in the oxidant output line can adjust the water production characteristic of the fuel cell in dependence on the loading of the system.

Abstract: 1,173,374. Non-contact-making relays; electro-mechanical networks. INTERNATIONAL BUSINESS MACHINES CORP. 3 April, 1967 [29 April, 1966], No. 15117/67. Headings H3B and H3U. [Also in Division H1] A resonator comprises a semi-conductor body 60 and an electrical heating element 70 formed in or on the body for causing mechanical strain due to differential expansion of the body. If the electrical, and hence the thermal, excitation is varied at a suitable frequency the body will resonate mechanically, producing a large mechanical strain. The heating element may be an electrical resistance element at the surface of the semi-conductor, an electrical resistance established through the semi-conductor body, a forward biased PN junction or a transistor operated to cause collector power dissipation. In each case the arrangement is such that more heat is supplied to the upper surface of the body than to the lower, so that the substrate bends. Alternatively, heaters may be provided on both surfaces and driven electrically out of phase. It is also suggested that the Peltier effect could be used. Strain in the substrate is detected by means of one or more piezo-resistors 72, 74, 76, or piezo PN junctions, or by reflecting light from the free end of the substrate towards a light detector. In the arrangement shown the piezoresistors are connected in series to a voltage source, with 72 in the middle, and an output voltage is detected at the junction between 72 and 74. By using resistors 72, 76 which have an equal and opposite temperature coefficient to resistor 74 output variations due to temperature changes are eliminated. In Fig. 8 the heating element 70 is a transistor and a control voltage is applied to its base to vary the emitter-collector current and hence the heating effect. Transistor and resistor devices 82, 83 are provided for amplifying the control and output signals 84, 85 being input and output connection tabs. A modification is referred to in which four piezo-resistors are connected to form a bridge circuit. Instead of operating in a flexual mode the device may be constructed to operate in a torsional or an acoustic mode. In a torsional arrangement the body is cylindrical and has the excitation and sensing elements arranged on a helical line at 45 degrees to the axis of the cylinder. In an acoustic arrangement the excitation and sensing elements are mounted on opposite end faces of the substrate which is attached to a support by way of the excitation element. An arrangement operating in the flexual mode but supported at both ends is also referred to. Higher order modes may be excited in the flexual mode devices. A band-pass filter may comprise a plurality of resonant devices each resonant at a different frequency and excited by the same input signal. The output elements of all the devices are connected in series.
