Abstract: 1520831 Mixed piezoelectric-piezomagnetic material; barium titanate PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Jan 1976 [10 Jan 1975] 00486/76 Headings C1J and C1A A material consisting of a mixture comprising a piezoelectric phase and a piezomagnetic phase and capable of converting an electric field into a magnetic field and vice versa is manufactured by preparing a starting mixture of materials which form a sintered mixture of the phases on heating, heating the starting mixture at a given temperature so as to form a sintered product, and continuing heating until a chemical equilibrium between the phases has been established at the given temperature. After the chemical equilibrium has been established the sintered product may be heated in a chemically active (e.g. oxidizing or reducing) atmosphere. The examples describe the production of a two phase mixture from CoCO 3 , Fe 2 O 3 , TiO 2  and BaCO 3  (Example I) and from BaTiO 3  and Ni 0À97 Co 0À03 M 0À10 Fe 1À90  O 4  (Example II). The BaTiO 3  of Example II is prepared by grinding BaCO 3  and TiO 2  in alcohol in a ball mill, drying and then heating for 16 hours at 1000 C.

Abstract: 729,629. Fishing lures. BROUGHTON, E. April 13, 1954. [Jan. 8, 1954] No. 585/54. Class 48. A Devon spinner comprises an inner support 1 and an outer sleeve 5 which can be detached from the inner support and the line 9 without removing the inner support from the line. The sleeve is detached by sliding it off the inner support on to the line and then passing the line through a longitudinal straight or curved slot 6 in the sleeve. In the embodiment shown the support also has a longitudinal slot 3 so that it can be removed from the line in like manner and the sleeve has an internal pin 7 which engages in a transverse slot 4 in the support to retain the sleeve in position. The sleeve may be held on the support by friction or the support may be barrel shaped so that the sleeve may be held by resilience. The two longitudinal halves of the support may be differently coloured and the sleeve may be opaque on one half and transparent on the other, a change in the colour of the spinner being made therefore by appropriate rotation of the sleeve. The sleeve is cigar shaped on its outer surface and is made of metal, plastic or rubber The support is made of relatively heavy metal and has a flange 2 at its rear end against which the sleeve abuts.

Title: Improved process of bleaching non-homogeneous cellulosic waste materials
IPC: D21C9/10
Filed: 1951-01-11
Abstract: Non-homogeneous cellulosic fibrous suspensions are first homogenized as by grinding in the presence of an emulsifying agent such as bentonite, and then bleached in a two stage process, in the first stage of which the whole of the chlorine required for the bleach is added at a pH below 3 and in the second the pH is raised to 6.5 to 10.  In an example, cotton waste in the form of pulp is ground, if necessary in the presence of an emulsifying agent to eliminate oil and grease, and washed until the particles are reduced in size to the average size of the particles constituting the pulp to be treated. The pulp is then brought to a consistency of about 3-4 per cent, mixed with chlorine and kept at a pH below 2.5 by adding hydrochloric acid.  Lime or other alkali is added to bring the pH to 6.5 to 8.5 and the temperature raised to 40 DEG  to 50 DEG  C.  Other examples are given in which old coloured rags and old paper, partly printed and coloured are treated in a similar manner.

Title: An improved process and apparatus for the catalytic combustion of ammonia with oxygen or gases containing oxygen
IPC: C01B21/26
Filed: 1932-01-12
Abstract: <PICT:0394406/III/1> In a process for the catalytic combustion of ammonia, the gas mixture is passed through the catalyst with a linear flow velocity which exceeds the linear velocity of combustion under the conditions existing in the catalyst.  The velocity of the mixture may be higher on entering the free gas space before the catalyst than it is through the catalyst proper.  A suitable catalyst consists of galloon or twilled galloon fabric of platinum-rhodium alloy, and cooling, e.g. by a liquid layer of water or nitric acid, may be applied if necessary.  In the arrangement shown, the gas mixture passes through a ring of circular holes 4 in the gas distributing disc 3 and radially along the space 8 between the disc 3 and a parallel disc 5 with very high velocity.  After changing direction it then passes with lower velocity through the catalyst consisting of platinum fabric 6 stretched across the passage 13.  In a modification the gas mixture passes radially through a number of parallel passages between several annular discs and then through the catalyst fabric as before. Specification 236,145, [Class 1 (i), Chemical processes &c.], is referred to.

Title: Transformers for thermionic valve amplifiers
IPC: H03F3/02
Filed: 1923-01-10
Abstract: 193,010. Lorenz Akt.-Ges., C., (Assignees of Scheppmann, W.). Feb. 11, 1922, [Convention date]. Thermionic amplifiers. - In order to prevent the amplification of undesirable frequencies, which give rise to " whistling " noises, a shunt circuit containing capacity C1 and inductance L1 is connected across the valve transformer windings, as shown. This circuit is tuned to the higher frequencies beyond the speech range, and consequently by-passes such energy and prevents its further amplification across the transformer. By adjusting the values of L1 and C1, the amplification of energy beyond a certain frequency can be cut off sharply, thereby producing the same effect as the more complicated filter circuits ordinarily used for this purpose.

Title: Improvements in and relating to the manufacture of brake drums
IPC: F16D65/10
Filed: 1935-01-10
Abstract: 447,348. Casting composite brake drums. CAMPBELL, WYANT, & CANNON FOUNDRY CO., Muskegon, Michigan, U.S.A. Jan. 10, 1935, No. 929. Convention date, Jan. 15, 1934. [Classes 83 (i) and 83 (ii)] Casting-machines.-A brake-drum ring 24 for motor vehicles &c. is made by pouring a molten alloy of iron with up to 15 per cent of copper or other metal of greater density into a centrifugal mould rotated fast enough to cause partial separation of the metals. The mould 4 may be of baked sand in a metal shell 1 which is clamped by wedges 16 into a flask 14. This is driven by a gear 28, and supported by bearings 9, 10 which are lubricated by means of a tank 11, propeller 12, and return tube 13, and can be arrested, when desired, by a brake 29. The molten metal is distributed by a cone 19 of metal located by a pin 18. The peripheral speed of rotation, is between 3000 and 5000 feet per minute, and the temperature of the pouring, between 2300 and 3000‹ F.; these are varied in relation to the composition of the alloy to give the desired degree of separation. The brake ring may be welded or otherwise secured to a back of rolled, wrought, or pressed steel. The Specification, as open to inspection under Sect. 91, comprises also casting the alloy into a steel shell, instead of into a mould, so that the molten metal becomes welded thereto. This shell may be wide enough for two drums and be divided after casting. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for qnti-corrosive protecting the internal wall surface of tubing
Inventor: SHISHKIN VIKTOR V
IPC: F16L58/10
Filed: 1985-10-16
Abstract: A method of protecting the inside surface of a pipeline against corrosion consists of a carriage which introduces a hose e.g. of polyethylene, aluminium or glass fibre tissue into the pipe, where it is inverted and forced by admitted compressed air to line the wall. An induction heater heats the wall surface so that the combination of pressure and heat causes the hose to adhere to the inside walls. - Compressor supplies compressed air in the pipe in which a hose, unwound from a drum, is fixed with its inverted free end to the inside wall. As the pressure urges the hose against the carriage with wheels, the surplus of a cable supplying power to the motor is wound on the drum. - The cable continues through the hollow shaft to a slip ring and supplies power to the induction heater coil. This heats the inside of the pipe enough to form a reliable bond with the hose.

Title: Incoming call connection system
Inventor: YOSHIDA TATSUYA
IPC: H04M3/42
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To limit the number of lines which can connect a call even if same incoming information are simultaneously received from plural lines at the time of an incoming call in the line notifying incoming information. SOLUTION: In a private exchange 100 storing plural lines such as dial-in lines and extension terminals, which notify incoming information of an incoming number at the time of an incoming call, a station subscriber telephone set 108 dials a line number decided in a public network 107, which corresponds to a central office 104. Thus, the incoming signal arrives at the central office 104 and the private branch exchange 100 recognizes that the incoming call arrives from the public network 107. Incoming information (line number) is received with a known procedure, which is previously decided between the public network 107 and the private branch exchange 100. A pertinent extension terminal 106 is call-connection-controlled by analyzing incoming information in a central control unit 102.  When same incoming information are received from the plural lines, the incoming call of the line when the line exceeds the number of lines that, can simultaneously connect the call, is limited.

Title: Backing strip device for circumferential welding of pipe
Inventor: INAMI RIYUUICHI
IPC: B23K37/053
Filed: 1979-01-08
Abstract: PURPOSE: To improve the durability of backing metals and enable welding work to be done stably by combining and incorporating stationary backing metals and slide backing metals to respectively movable segments.  
     CONSTITUTION: Each arc-form segment which is held extensibly in the pipe radial direction from the pipe axial center is formed by a stationary segment 11 and a slide segment 12 which slidably holds a backing metal 13. The both segments 11, 12 are made movable by separate cylinders. If the both segments 11, 12 are moved toward the pipe inside surface, the stationary segment 11 remains mounted and the slide metal 13 of the slide segment 12 slides axially with bars 18, 24 as a guide, thereby evening the gap between the inside surface of the pipe and the backing metal. Hence, by this backing strip device, the pipe inside circumference is evenly welded.

IPC: H04N1/409
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To restrain electrostatic offset and to obtain an excellent image by performing exposure by which the thin line of an original is emphasized more in an OHP mode than in an ordinary transfer paper mode in a digital copying machine. SOLUTION: In the case of using the printer function of the digital copying machine, whether the OHP mode is selected is checked first (S601). When the OHP mode is not selected, in other words, in an ordinary transfer paper passing mode, laser exposure to ordinary transfer paper is performed (S602). When the OHP mode is selected, the exposure is performed by increasing the power of a laser beam (S603) after performing control to make the adhesive amount of toner transferred to the OHP sheet smaller than in the ordinary transfer paper mode in order to prevent the electrostatic offset, and printing processing is executed respectively (S604). Namely, the exposure by which the thin line of the original is emphasized more than in the ordinary transfer paper mode is performed.
