Title: Improvements in the manufacture of siloxane resins
IPC: C08G77/00
Filed: 1947-01-07
Abstract: A process of preparing organo-polysiloxane resins from mixtures containing phenyl and methyl substituted silicon chlorides produced by interaction of silicon tetrachloride with phenyl and methyl Grignard reagents, whereby phenyl and methyl radicals are coupled with silicon by carbon-silicon linkages is characterised by vaporizing from the crude reaction mixture silicon tetrachloride and the low boiling methyl silicon chlorides in which the only organo radicals are methyl radicals, leaving a residue containing the higher boiling silicon chlorides which each contain at least one phenyl radical, hydrolysing the still residue and methyl silicon trichloride in admixture with each other, and copolymerizing the hydrolysis products to form a bodied resin. The preferred resins result when 10 to 30 mol. per cent of phenyl silicon trichloride is present in the still residue, the rest being mainly phenyl methyl silicon di-chlorides.  A suitable mixture is obtained by using an equimolecular mixture of methyl and phenyl Grignard reagents and adding it to SiCl4 in a total ratio of 2.1 to 1.  Distillation at 70-190 DEG  C. removes the silicon tetrachloride and methyl silicon chlorides.  Methyl silicon trichloride is added to the still residue to form 5 to 40 mol. per cent of the total, and the mixture is preferably hydrolysed in the presence of a solvent.  The product may be bodied by heating or acid or basic catalysts, or both.  In an example, equivalent amounts of methyl and phenyl Grignard reagents are reacted with silicon tetrachloride in presence of toluene. The product is distilled to remove methyl silicon chlorides and silicon tetrachloride, methyl silicon tri-chloride is then added, and the mixture hydrolysed in stages, replacing by water the hydrochloric acid formed after each stage.  The solution is concentrated and the product bodied in solution in an organic solvent.  The resins cure at 250 DEG  C.  They may be used for coatings, impregnating coils, motor stators and transformers, for varnishing glass fibre fabrics or securing mica to glass cloths.  The Specification as open to inspection under Sect. 91 comprised also a process of hydrolysing the still residue, hydrolysing methyl silicon trichloride, and copolymerizing the hydrolysis products.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to variable electric condensers
Filed: 1939-01-07
Abstract: 523,584. Variable condensers. FIDES GES. FUR DIE VEBWALTUN'G UND VERWERTUNG VON GEWERBLICHEN SCHUTZRECHTEN. Jan. 7, 1939, No. 625. Convention'date, Jan. 7, 1938. [Class 37] One electrode 31 is borne on the outside of a tubular ceramic &c. member 26 having a bore into which is fitted a tubular or solid member 28 carrying a second electrode or electrodes 29, 30 shown as covering a part of the inner surface of a tube. By rotating the inner member the capacity between the electrodes is varied owing to the varying of the thickness of the dielectric. Variation in the nature of the dielectric' can be introduced by having bores 32 containing air. The inner electrode is screened in all positions by the outer. In modifications, the outer member is of circular section, the bore being eccentrically placed, or the outer member may have a section of spiral outline and air bores are of circular, flat or arcuate section. In the modification, Fig. 13, variation of capacity can be effected by either axial movement or rotation or a combination of both, by making the outer member 39 of varying crosssection along its length and longer than the inner member 42. In this case, also, air chambers 44 may be introduced into the outer member.

Title: Improvements in or relating to the manufacture of bases for electric discharge vessels
IPC: H01J9/32
Filed: 1942-01-19
Abstract: 555,244. Glass-metal seals. JONES, W. G., and PYE, Ltd. Jan. 19, 1942, No. 752. [Class 36] [Also in Group XXIII] In moulding glass bases for thermionic valves and other electric discharge devices, a number of short lengths of glass tube 49, Figs. 5 and 6, together with lead-in wires 48, are assembled between dies 33, 34, which are rotatable about the same horizontal axis, the assembly is heated by burners 50, and then the dies are pressed together to mould the softened glass into the desired shape with the lead-in wires tightly sealed therein. A machine for carrying out the invention comprises two die heads 10, 11, Fig. 1, which can be moved to and from one another by means of a crank disc 27 operated by a handle 28 and are splined on coaxial horizontal shafts 12 that rotate in synchronism. Springs 30 normally hold the die heads in open position as shown. The head 10 carries a sheath 36 which is slidable along the head and has at its forward end a die-aligning ring 37 that slides over the die 33. A spring normally holds the sheath in the retracted position The dies 33, 34 are secured to the die heads and are provided with holes to receive the lead-in wires. Behind each die is a plunger 42, the stem of which slides in an axial bore in the shaft 12. Each plunger is pressed forward by a spring, but it can be moved to its forward and rearward positions, and locked therein, by means of a ring 47 which is loose on the shaft 12. In use, the glass tubes and the lead-in wires are assembled between the heads, the dies are then set into rotation and the tubes are heated by the gas jets to soften the glass and to heat the wires to sealing temperature. When the glass is soft, the handle 28 is moved to press the dies together to shape the softened glass. The first movement of the handle advances the ring 37 to close the join between the dies. After pressing, the dies are moved to their rearward positions by means of the rings 47 to permit removal of the finished article. In some cases, the wires may be headed with suitable sealing-in glass before being placed in the dies.

Patent GB-352979-A (GB)
Title: Improvements in or relating to engines and the like of the swash-plate type
IPC: F16H23/00
Filed: 1930-01-09
Abstract: 352,979. Balancing reciprocating engines, pumps, &c. CRAIG, J. N. F., The Wilderness, Broxbourne, Hertfordshire. Jan. 9, 1930, No. 880. [Class 122 (iii).] In engines, pumps, motors and blowers having swash-plate driving-gear with a fixed plate and revolving cylinders, the centrifugal force of the pistons is taken by an equalizing member which rotates about the axis with the cylinders and is connected to the pistons through weighted levers which counter their centrifugal forces. The axial acceleration and retardation forces of the pistons are also balanced. The swash plate 10 is connected to the rotating cylinders by bevel gearing so that it is positively rotated at the engine speed. The swash plate is supported by a bearing 9 of the " Michell " type with pads 11. The cylinder block 3 contains seven cylinders 4 and radiating fins 5. The internal and external fins are connected by radial passages between the cylinders. Fluid distribution is controlled by a valve ring 7 as described in Specification 352,959, [Group XXVII]. The swash plate carries teeth 13 engaging teeth 14 on a bevel wheel on the shaft. Ball castors of the type described in Specification 327,764, [Class 122 (iii), Steam engines, Kinds &c.], are arranged between the pistons and the swash plate, and engage bearing-pieces 17 on the pistons. A piece 18 is secured to each piston and engages a spherical, swash-plate bearing surface 19. The gudgeon pins 21 carry weighted levers 22 and pivot on ballson curved levers 23 pivoted at points 24 to a yoke 25. This construction takes the centrifugal force of the pistons. One or two links 23 may be rigid with the yoke and constitute master links. A modification is described wherein the engine shaft has a spherical portion upon which is freely mounted a slightly conical, equalizing-plate. At its edge the plate carries weighted equalizing levers which engage through spherical joints the inner sides of the pistons. The centres of gravity of the pistons are spaced from the spherical joints to allow the pistons to oscillate as pendulums with a period corresponding to the rate of revolution. The construction eliminates " slap " due to reversal of action. Fan blades are mounted on the shaft to drive cooling air through the fins and radial passages.
Patent HK-14092-A (HK)
Title: Electronic time piece with a possibility of adjusting the seconds indication
Inventor: MEISTER PIERRE-ANDRE
IPC: G04G21/00
Filed: 1992-02-20
Abstract: A timepiece, able to indicate at least the hours, minutes and seconds, having a rotary stem movable into three axial positions: a stable neutral position in which the timepiece operates normally, a stable outer position and an unstable inner position. When the stem is pulled to the outer position the timepiece switches from the normal operating mode to a correction mode in which it is possible either to correct the minutes indication by rotating the stem slowly, or to perform a change of the hours indication done by rotating it rapidly. Whenever the stem is simply pulled out, or is pulled out followed by a correction of the minutes indication, and is then returned to the neutral position, the timepiece switches automatically and for a set maximum time, e.g. one minute, to a transitory mode in which it is possible to reset the seconds to zero and, at the same time, to cause a return to the normal operating mode by pushing in the stem. If after a set time, no pressure has been exerted, the timepiece resumes automatically normal operation. No transitory mode is provided when only a change of the hours indication is performed.

Title: Magnetic head device
Inventor: TAKADA YOSHIAKI
IPC: G11B5/60
Filed: 1986-01-07
Abstract: PURPOSE:To shorten the total length of the wire leading out part and to form a magnetic head device mountable on a small-sized and large-capacity magnetic disk device, by assembling the magnetic head device under a condition where linear sections are provided at one or more sections of its magnet wire leading out part. CONSTITUTION:When one or more linear sections 2a are provided at a wire leading out part at the time of assembling a magnetic head device with a magnetic head core 3 or 4 provided with winding, the total length (l) of the wire leading out part can be made shorter without receiving any influence from the elasticity of a magnet wire 2. If the magnetic head device is fitted to the upper and lower surfaces of a magnetic recording medium at the time of assembling a magnetic disk device, the direction in which the magnetic head device is fitted to a magnetic head core supporting spring 1 becomes opposite, but, when the wire leading out part is set in the opposite direction, a similar effect is obtained.

Title: Calorimetry for fuel
Inventor: UCHIYAMA YOSHIHIRO
IPC: G01N25/28
Filed: 1981-01-07
Abstract: PURPOSE:To make it possible to continuously measure the energy level of fuel which is a combination of temperature of a produced fuel and its calorific value, by making the perfect combustion of the fuel by mixing a part of it with air of a fixed condition and flow rate, and then, by measuring temperature of the combustion gas. CONSTITUTION:Fuel gas 19, which flows in a fuel pipe 6 located on the entry side of a gas turbine burner, is sampled by a sampling tube 20 and fed to a small-type burner 23 after passing through a fuel supply pipe 31, a pressure reducing valve 21 and an orifice 22. On the other hand, combustion air from a  compressor 1 enters the small-type burner 23 after passing through an air supply pipe 27, a pressure reducing valve 28 and an orifice 29, and it is mixed with  the fuel in an inner tube 26 of the burner and burned to produce combustion gas 32. As the fuel gas and air entering the burner 23 are maintained at an almost fixed condition, a temperature of the gas 32 measured by a temperature  detector 24 is to indicate an energy level including sensible heat of the fuel gas.  It is possible, by doing so, to measure only an energy level including sensible  heat by extracting it from variables of the combustion gas entering the gas  turbine burner.

Title: Liquid-cooled resistor and manufacture thereof
Inventor: FUJIMOTO TAKAFUMI
IPC: H01C1/08
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To supply a liquid-cooled resistor which is prevented from leaking cooling water, cools with high efficiency, and has long life. SOLUTION: Split internal cylinders 6a-6d are severally inserted from the upper side of the internal cylinder for joining together in an external cylinder 1, thus an internal cylinder is constituted. After the internal cylinders 6a-6d are inserted into the external cylinder 1, a lid and a delivery tube are fixed. By dividing the internal cylinder into a plurality of pieces in such a manner as this, a case where the internal cylinder is inserted on the tilt against the external cylinder is eliminated, and no gap is generated between a water drip shed 8 of the internal cylinder and the inner periphery of the external cylinder 1, so that no leakage of cooling water is caused. Thereby a resistance wire is normally cooled, and long life of a resistor is realized.

Title: Brushless dc motor
Inventor: TAKABA YOSUKE
IPC: H02K29/00
Filed: 1987-01-07
Abstract: PURPOSE:To obtain torque characteristics stable and without torque ripples, by forming a slot skew between the grooves for inserting coils between each stator core and the auxiliary grooves of end faces of tooth sections facing the air gap. CONSTITUTION:The tooth section 3a of a stator core 3 is massively formed. Between each stator core 3 is formed a groove 5 for inserting coils to insert and hold exciting coils 4. An auxiliary groove 3a B is formed in addition to the end face 3a A of each tooth section 3a of the stator core 3. Each air gap 12 is made equivalent with a skew between the groove 5 for inserting coils and the auxiliary grooves 3a B so as to control the skew angle of the stator core 3. On that account, the drop amount of generated torque on the shoulder increases. Further, the nearer the air gap section 12 gets to the shoulder section 10b of a magnet 10, the narrower will it be. As a result, the drop amount of torque at the shoulder section 10b will increase accordingly. The torque generation in a flat characteristic condition is thereby implemented.

Filed: 1985-01-07
Abstract: PURPOSE:To improve rising temperature characteristics at heat development temperatures, to shorten a development time, and to obtain excellent picture quality by controlling stepwise electric power or a voltage supplied to a feed heating body for a heat development photosensitive material. CONSTITUTION:An AC power source 2 supplies electric power to the feed heating body 1 through a two-way three-terminal thyristor 3. The voltage to the heating body 1 is detected by resistances R1 and R2 and rectified by a rectifying circuit 4, and then compared by a comparator 4 with a stepwise voltage signal from a sequence 5 and a D/A converter 6. A phase control circuit 8 controls the firing angle of the thyristor 3 according to the output of a comparator 7 to control stepwise the voltage applied to the feed heating body 1.

Title: Volume reducing apparatus for waste plastics material
Inventor: NAKAZONO MITSUSACHI
IPC: B29B17/00
Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To carry out treatment of reducing a volume of waste plastics without locking owing to intrusion between a treating container and a piston of the waste plastics softened during the treatment of reducing the volume by a method wherein a blower and a heating part heating circulating gas are equipped to a hot-air circulating route, and an intrusion preventive material is provided onto a side face of the heating part. SOLUTION: A vertically movable pressurizing part 3 is provided to a bottom part side a treating container 2, and waste plastics material 30 softened by hot-air of about 160 deg. is reduced in volume by surface pressurizing between the pressurizing part 3 and an opening and closing cover 6. The pressurizing part 3 is composed of a pressure actuator 4, a piston 28, and an intrusion preventive material 25. The intrusion preventive material 25 having a plurality of projected pieces, though waste plastics material 30 is going to intrude a gap by being softened, can prevent the intrusion by supporting the softened plastics waste material with an adjacent projected piece even at a position having no- projected piece because of its large viscosity.  Thus, the pressurizing part 3 is prevented from being locked owing to intrusion of the softened waste plastics material 30 between the pressurizing part 3 and the treating container 2.
Patent JP-S63169092-A (JP)
Title: Semiconductor laser
Inventor: ITO TATSUYA
IPC: H01S5/16
Filed: 1987-01-06
Abstract: PURPOSE:To eliminate the need for establishing difficult process conditions and obtain a semiconductor laser that is favorably reproducible by forming a current bottleneck layer like a stripe in the direction of optical axis and also in the position corresponding to an external waveguide layer at both sides of an active region on a substrate. CONSTITUTION:Recessed grooves 1b and 1c are formed by photolithography on an upper plane of a p-InP substrate 1. In such a case, widths of the recessed grooves 1b and 1c are formed so that they are equal to that of an external waveguide layer 4 or slightly larger than that of the layer 4 and there is a somewhat difference between both widths of the grooves and the layer. Further, their positions are so correspondent to a position of the waveguide layer 4 in a distributed reflection region that the grooves are formed at both sides of an active region where a part of the active region used as a current path is excluded. Then N-InGaAsP current bottleneck layers 15 perform an epitaxial growth on the substrate 1. In such a case, a width between 1b and 1c is so narrow that it is filled with its growth in a short time and its upper plane becomes flat. This approach makes it possible to form simply the current bottleneck layers that are favorably reproducible without establishing difficult process conditions.

Title: Gate circuit of gate turn-off thyristor
Inventor: SENDA KATSUNORI
IPC: H02M1/06
Filed: 1985-01-09
Abstract: PURPOSE:To decrease variance of a turn-off gain regardless of the quantity of a cut-off current by adopting a saturated reactor for a reactor turning off a gate circuit. CONSTITUTION:A saturated reactor 10 is connected to the gate circuit. Since carriers drawn out of the gate are increased as the turn-off current is increased, the gate current is increased but the reactor is saturated gradually. As a result, the fluctuation of the turn-off gain is suppressed to a low value. Thus, the variance in the turn-off gain is reduced independently of the quantity of cut-off current.
