Inventor: UIRIAMU EE MATSUSEI
IPC: G06Q50/00
Filed: 1997-01-06
Abstract: PROBLEM TO BE SOLVED: To reduce the cost and the queuing time for an unsteady queue system having an infinite number of servers by disposing the servers based on the probability distribution that is decided based on the mean value function and the distribution function of the number of servers which are working in the queue system. SOLUTION: A queue system 100 comprises a queue 105 of customers 101-1, 101-2... and a service place 120 including the servers 115-2 to 115-n and the service areas 112-1 to 112-n. Then the probability distribution function of the number of busy servers of an unsteady infinite server queue system is decided as a time function based on the arrival rate of customers of a finite server queue system and an input parameter of the service time distribution, etc., set against the customers already arrived at the finite server queue system. The probability distribution is characterized by the mean value and the distribution function which are decided based on the input parameter.

Filed: 1990-03-21
Abstract: The device in hand-powered tools is designed for transmitting torque to hammer drill tools, locking bodies 7 interacting with recesses 6a axially closed on both sides, and drive bands 2b, 2c interacting with rotational drive grooves 6c, 6d distributed around the circumference of the tool shank 6.  In order to avoid incorrect use, the rotational drive grooves 6c, 6d are arranged so that under no circumstances do two rotational drive grooves 6c, 6d lie diametrically opposite one another.  In order to be able to produce the rotational drive grooves 6c, 6d economically by means of a chipless forming method, the sum of the cross-sections of the rotational drive grooves 6c, 6d is equal on both sides of a longitudinal plane (X) running through the recesses 6a, so that the same volume of material has to be deformed on both sides of the said longitudinal plane (X), thereby resulting in a uniform distribution of the forces generated thereby. <IMAGE>

Title: Process for the level dyeing of natural or synthetic polyamide fibres
IPC: D06P3/10
Filed: 1961-01-03
Abstract: Natural or synthetic polyamide fibres are dyed with water-soluble dyestuffs containing at least one group, other than a mono- or di-halogeno-1, 3, 5-triazinyl group, capable of reacting with the fibre, in the presence of a non-ionic dispersing agent and a cationic substance of the formula:-  <FORM:0969855/D1-D2/1> wherein R-CO- is the residue of an aliphatic, saturated or unsaturated carboxylic acid containing 12-22 carbon atoms, R1 is a divalent bridge with 2-6 carbon atoms of which at least two lie directly between -NH- and -N, -R2 and R3 are alkyl radicals of 1-5 carbon atoms, R4 is an alkyl radical of 1-5 carbon atoms or a benzyl or phenylethyl radical, which may be substituted, and A- is a monovalent anion. The dyestuffs may be of the azo, anthraquinone, phthalocyanine or nitro series and numerous examples are given.  Specified non-ionic dispersants are alkyl- or alkenyl-polyglycol ethers, alkyl- or alkylaryl-thiopolyglycol ethers, and the condensates of ethylene oxide with fatty acids, fatty acid amides, fatty acid mono- or poly-esters of sugar or with polypropylene oxide. Numerous quaternary ammonium compounds of the above formula are also specified.  Dyeing is carried out at 50 DEG -110 DEG C., the dyebath also containing, if desired, the usual adjuvants such as ammonium acetate, sulphate or phosphate, sodium sulphate, ethyl lactate, ethyl tartrate, acetic acid or formic acid.  The dyebath pH may be adjusted to 7-10 at the end of the dyeing process by addition of an acid-binding agent such as ammonia, sodium or potassium carbonate, sodium bicarbonate, disodium- or trisodium-phosphate, hexamethylene tetramine, trimethylamine, mono-, di-, or tri-ethanolamine or pyridine. Treatment of wool with ammonium thioglycollate, before, during or after dyeing, also improves the wet-fastness of the dyeing. Specification 966,312 is referred to.

Title: Gyroscopic apparatus
Inventor: HAMMOND EDMUND B
IPC: G01C19/44
Filed: 1954-01-05
Abstract: 760,251. Electric indicator systems. SPERRY CORPORATION. Jan. 5, 1954, No. 314/54. Class 40 (1). [Also in Group XX] Gyroscopic apparatus mounted in an aircraft for indicating the vertical and horizontal is compensated for errors introduced by linear and centrifugal acceleration by applying a tilt to the gyroscope in accordance with the horizontal speed of the craft and the rotor speed. As shown, Fig. 1, the gyroscope, mounted in a casing 1 with its rotor rotating about a vertical axis, is pivoted on horizontal axis 3 in gimbal 2, itself mounted on horizontal axis 4 in gimbal 5, which is journalled on a horizontal axis 6. A vertical follow-up ring 8 is also journalled in gimbal 5 about axis 4. Roll movement of the craft on which the gyroscope is mounted produces a signal from inductive tranducer 23 by relative movement between an armature 24 attached to the casing 1 and coils mounted on the ring 8, which is fed to amplifier 22 causing motor 19 to drive the fore-and-aft trunnion 6<SP>1</SP> to reposition gimbal 5. Pitch movement of the craft produces a signal from pick-off 34 by relative movement between the horizontal ring 2 and vertical ring 8, which is fed to amplifier 26, causing motor 21 to drive the trunnion 4<SP>1</SP> to reposition ring 8. A pendulum 9 pivoted at 10 on an extension 11 of the ring 8 has a pin 13 engaging in a slot in the casing 1 so that the tilting of the ring 8 causes the pendulum 9 to bring the gyroscope back to the vertical. Roll movement of the gyroscope is similarly corrected by a pendulum 14 attached to ring 8, acting through the forked arm 16 and pin 18 on ring 2. It is stated that to correct for errors introduced by linear and centrifugal accelerations the gyroscope must be tilted at an angle dependent on the horizontal speed of the craft. Hence a true speed signal obtained at meter 31 is fed to a potentiometer 33<SP>1</SP>, and multiplied by a factor depending on the angle of climb or dive obtained by a resolver 27 to give the horizontal speed of the craft, and this signal is subtracted from that received from pick-off 34 to actuate the pitch follow-up motor 21, whereby the ring 8 is maintained vertical, but the gyroscope 1 is processed to an inclined position to correct for accelerations. The apparatus contains visual indicators 40, 41, 42 to indicate pitch, and 43, 44 to indicate roll. Specification 637,993, [Group XX], is referred to.

Abstract: 1498303 Cameras FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE 6 Jan 1976 [14 March 1975]  00332/76 Heading G2A In a camera, the film transport is driven by linear movement of a slider 5, this being coupled with a cover plate 6, which covers or uncovers the viewfinder 3 and lens 2, in such a way that a certain limited relative movement a between them is possible. Fig. 2 shows the inoperative position, in which the viewfinder and lens apertures are covered by plate 6. To move the parts to the operative position of Fig. 3, slider 5 is moved to the left, which drives a film transport device (not shown). Slider 5 has an extension 8, which fits into a recess 9 of plate 6, and so does not engage with the plate until it has moved a distance a, after which the two move together. The distance moved by the slider to wind on the film one frame length will vary, since the diameter of the film on the take-up spool is constantly increasing. The transport is terminated by a feeler dropping into a film perforation. A lever 16, spring-biased anticlockwise, bears against the underside of a projection 14 on plate 6. When the plate has moved sufficiently to the left, lever 16 engages behind projection 14 and pushes it further still Fig. 3. This ensures that plate 6 is moved completely into its "open" position, irrespective of further displacement of slider 5. After exposure, the parts are returned to the original position of Fig. 2 by moving slider 5 to the right. This movement may be coupled to the shutter cocking mechanism.

Patent GB-790311-A (GB)
Title: Phthalic acid preparation
IPC: C07C51/347
Filed: 1955-01-10
Abstract: Benzene dicarboxylic acids are prepared by reacting a C1 to C4 alkylbenzene monocarboxylic acid with a cyano-benzene carboxylic acid at 350-750 DEG  F., an interchange of position being effected between the nitrile group of the latter and the carboxyl group of the former, to give a phthalic acid and a C1 to C4 alkylbenzene nitrile.  The C1 to C4 alkylbenzene monocarboxylic acid may be prepared by contacting a di- or poly- C1 to C4 alkylbenzene with oxygen at 250-500 DEG  F., and the cyanobenzene carboxylic acid may be prepared by oxidizing a C1 to C4 alkylbenzene nitrile or an amide or ammonium salt of a C1 to C4 alkylbenzene carboxylic acid under similar conditions or by dehydrating mono-amides or mono-ammonium salts or mixtures thereof of benzene di-carboxylic acids.  The alkylbenzene carboxylic acid and the alkylbenzene nitrile may be oxidized separately or in a common oxidation zone, and pressures of from atmospheric to 300 p.s.i.g. and catalysts comprising oil-soluble compounds of cobalt, manganese, chromium, nickel or lead, such as cobalt toluate or naphthenate, may be used.  In the interchange reaction, excess alkylbenzene mono-carboxylic acid may be used and ammonium sulphate, sodium hydrogen sulphate, or sulphuric acid may be present as a catalyst. The alkylbenzene nitrile formed in the reaction is continuously removed as vapour and recycled to the nitrile oxidation stage.  The phthalic acid product is separated from excess alkylbenzene monocarboxylic acid by conventional means, the latter being recycled to the interchange reaction stage.  Specified alkylbenzene starting materials are m- and p-xylene, trimethylbenzenes, methylethylbenzenes, diethylbenzenes, triethylbenzenes, methylpropylbenzenes and methylisopropylbenzenes.  Alkylbenzene nitriles specified are m- and p-tolunitrile, dimethyl-, trimethyl-, ethyl-, diethyl-, triethyl-, propyl- and isopropyl-benzonitriles. The continuous preparation of isophthalic acid from m-xylene and m-tolunitrile is described.  Examples describe the preparation of: (1) tetephthalic acid from p-xylene and p-tolunitrile; (2) isophthalic acid from m-xylene and m-tolunitrile; (3) 5-methyl-isophthalic acid by oxidation of mesitylene to mesitylenic acid which is heated with 3-methyl - 5 - carboxy - benzonitrile obtained by oxidation of 3 : 5-dimethylbenzonitrile; (4) terephthalic acid from p-xylene and p-toluamide; and (5) terephthalic acid from p-xylene and ammonium p-toluate.
