Abstract: 1,245,016. End-testing cigarettes. R. J. REYNOLDS TOBACCO CO. 5 Aug., 1969 [19 Aug., 1968], No. 39024/69. Heading A2C. In an apparatus for inspecting cigarette ends comprising means for conveying cigarettes in individual holders through an inspection station; means for inspecting the cigarettes for defective ends; and means for rejecting cigarettes found to be faulty; the inspecting means comprises a plurality of inspecting devices, each mounted on said conveying means at an individual holder for travel with and spaced from the end of a cigarette held therein as it moves through said station. The cigarettes S are carried in flutes 9 of a rotating inspection drum 4 which comprises a central body portion 10 and end plates 11, 21. Sets of ports 12, 13, 14 in the end plate 11 are each aligned with each flute 9, and communicate, via a stationary shoe 15, with lines 30, 31, 32 when in the inspection region. The cigarettes S are held in the flutes 9 by a guide rail 6 when passing through the inspection region, satisfactory cigarettes being then allowed to drop out of the flutes 9 onto a conveyor (5) at a transfer station (C) while faulty cigarettes are retained in the flutes 9 by vacuum applied through spool valves 16 to openings 18a in the flutes 9. The faulty cigarettes are subsequently rejected by centrifugal forces overcoming the vacuum for collection in a receptacle (40) at a point beyond the transfer station (C). In the inspection region test air is supplied from a control unit (P) through a line 30 to the port 13. The port 13 leads to a chamber 13a which also communicates with the port 12 which latter acts as a sensor. Abnormal air pressures detected by the sensor port 12, due to the presence of cigarettes S with defective ends, are passed by line 31 to the control unit (P) where they initiate a signal in the form of a compressed air pulse which is fed via the line 32, the port 14 and a passage 14a into an appropriate passage 19 to move the spool valve 16 associated with the particular cigarette being tested to the position shown in the top half of the figure, thereby providing communication between the associated openings 18a and an associated conduit 18. The conduit 18 is then connected via a stationary shoe 24 to a vacuum source and then, after the faulty cigarette has been rejected, to a purging air source to clear any residual vacuum and remove any defective cigarettes that have not been previously removed. Just beyond the purging point, a further compressed air signal is applied through a port 23 in the shoe 24 into passages 20 associated with each spool valve 16 to reposition those of the latter that have been displaced.

Abstract: 391,431. Coke ovens; charging and discharging. NAAMLOOZE VENNOOTSCHAP MAATSCHAPPIJ VOOR KERAMISCHE EN CHEMISCHE INDUSTRIE KEROCHEMICA, 452, Heerengracht, Amsterdam. July 23,1931, No. 21110. Convention date, April 22. Void [Published under Sect. 91 of the Acts]. [Classes 51 (ii) and 55 (i).] A method of operating coke ovens comprises covering the coal charge with a permeable layer of small heat conductivity, so that the distillation gases are cooled during their removal from the coal, decomposition due to heat is avoided, and the distillates from the preliminary distillation do not react with those given off at higher temperatures. This layer may consist of coke, loose ceramic material, or stones 40, or a perforated block of fire-brick 62, and may be cooled by a liquid spray, or by circulation of a cooling fluid. The gas collecting space over the fuel may be cooled by reducing the thickness of the oven roof. The tops of the coking chambers 3 extend above the heating flues 5. The coke pusher 12 with a head 13 is carried on a frame 10 mounted on rails 9, and a coke guide car 16 travels on rails 15 at the opposite side of the oven, the guide-box 18 being moved to and from the oven on rails 17. On discharge, the covering layer 40 is separated from the coke cake by a horizontal partition 46, from which leads a channel 47 directing the loose layer into a receiver 48, the coke falling into a hopper 49 on a quenching car 50. The charging car 20 is mounted on rails 19 on the oven roof, and carries four hoppers 21 and 38 for coal and covering material respectively. The leveller 24 is supported on rollers 25 on bell-crank levers 26 mounted on the car frame 10, the lower arms of the levers being attached to a push rod 28 moved backwards and forwards by a screw 29, so that the leveller may be raised or lowered to level the surfaces of the loose material, and coal charge respectively, through doors 41, 37. The leveller is traversed by a cord 32 secured to it at 33, and wound on a drum 35, on rotation of which the leveller is advanced into or retracted from the oven. Retaining plates 42 are provided in the oven to prevent the loose layer near the doors from falling out when the latter are opened. An ascension pipe leads from the gas space to a main 45. Cooling channels 57, Fig. 11, may be formed at the top of the oven chambers and supplied with cooling agents such as water or air. Shaped blocks 62, Fig. 12, traversed by channels 63, may be inserted over the charge, and are supported by rods 64 connected by a cross-head 67 carried by a raising lever 68 actuated by a worm and worm-wheel 70 from a hand-wheel 72. These blocks, which exert pressure on the charge, may, in a modification be suspended from oven covers. The coke is discharged on to conveyers which lead to a sorting plant from which the small coke may be separated, and used as the covering material.

Title: Bipolar analog to digital converter
IPC: H03K/
Filed: 1966-09-02
Abstract: 1,101,969. A/D converters. INTERNATIONAL BUSINESS MACHINES CORPORATION. 2 Sept., 1966 [7 Oct., 1965], No. 39210/66. Heading G4H. In an analogue to digital converter of the kind in which the unknown signal is quantized to obtain the highest significant digit, and reduced by the equivalent of this digit, the remainder being multiplied by the radix and the process repeated for successive digits, the converter is adapted for inputs of either polarity by means which produce a true digital representation for the highest digit, if the input is positive, and a complementary digital representation when the input is negative so that the remainder is positive for both positive and negative inputs. The input 19, Fig. 1, is first switched by 151 to positive digitizer 300 comprising nine threshold circuits having different levels (0, 1, 2, 3, 4, 5, 6, 7 and 8 volts) and negative digitizer 400 having seven threshold circuits (with negative levels 1, 2, 3, 4, 5, 6, 7 volts). The outputs are combined in comparator Or circuits 500, are temporarily stored at 600 and are recoded at 700 into three binary scale bits, an " M " bit, signifying that the value is negative and a " P " bit indicating that the input exceeds the maximum positive range of the converter. In the case of a negative value the binary digit is the 7's complement of the input value. These bits are stored at 251 for the highest digit and at 252, 253, 254 for subsequent digits. The value stored at 251 is converted in a digital to analogue converter 201 to a voltage which is subtracted fromthe input and the difference multiplied by the radix 8 at 181. This value is then passed by switch 152 to the digitizers 300 and 400 and the process is repeated to obtain the next digit. When a binary digit is stored in any of stores 251-254 without an M or P bit the output of the DAC 201-204 is proportional to the stored digit. If an M bit is present the output is negative and has the value of the complement to 8 of the stored value. If the input is - 0À0246 volts (expressed in radix 8) the digitizer 400 produces no output and the recorder 700 produces outputs on leads 4, 2, 1 and M. This value of 7 is the complement to 7 of the value 0. When applied to the converter 201, the output produced is the complement to 8, i.e. - 1, and, when subtracted from the input value at 181, a positive difference is obtained which when multiplied by the radix 8 gives 7À532. The following digits are determined as for the positive input by successively subtracting quantized digit values and multiplying by 8 between steps. Error correcting arrangements are provided to compensate for threshold circuits in digitizers 300 and 400 which fire when they should not, or fail to fire when they should. The values stored in the stores 251- 254 and in the recoder 700 at the end of the digitizing steps are added at 800 and gated out in parallel by gates 900. The circuits are controlled by a timing circuit 100. The circuits are described in detail.

Title: Improvements in or relating to methods of and control installations for machining bychip-removal
IPC: B23B25/02
Filed: 1962-10-17
Abstract: 991,336. Lathe details; boring machines. G. FISCHER A.G. Oct. 17, 1962 [Oct. 17, 1961], No. 39377/62. Headings B3C and B3T. In a method of machining by chip removal, as for example in a lathe, relative reciprocation between the cutting tool and workpiece is effected transversely to the cutting tool axis. The frequency of reciprocation is related to the speed of rotation of the workpiece such that an out-of-phase relationship is produced wherein reciprocations during one whole period of rotation differ from the number of reciprocations in the next whole period of rotation so as to produce a non-uniform chip. The cutting tool is reciprocated by fluid means 17, 19, controlled, via a control valve 26, by valves 24 and 28 which are actuated by cams 6 on cam discs 5 and 4, respectively, from the machine spindle 3. The out-of-phase relationship is effected by valve 29 which is actuated by a cam disc 10 which is driven through gears 7 and 8 at half spindle speed. Also, the cams 6 are identical but are offset in relation to one another so that a cam crest on disc 5 corresponds to a trough on cam disc 4. The tool 22 therefore completes a reciprocation which is staggered by half a reciprocation with respect to the preceding revolution of the workpiece. A chip produced from a workpiece by this method is shown in Fig. 5. In an alternative form of operation an electrical control installation is incorporated in which impulses, from electrical contacts associated with the cams on the machine spindle, are fed into an amplifier which is connected to a control valve to effect reciprocation of the fluid means attached to the cutting tool. In the embodiment shown in Fig. 6, the method of chip removal is applied to a boring machine. The tool reciprocations are effected by mechanical means in the form of a bell cam and the phase and frequency between the tool reciprocations and rotation is effected by selecting suitable gear ratios. The method described is applicable to reciprocation of the tool or workpiece and the rotation of the tool or workpiece.

Abstract: 1,156,126. Valves. SVENSKA PRECISIONSVERKTYG A.B. 29 Aug., 1967 [14 Nov., 1966], No. 39451/67. Heading F2V. [Also in Division G3] Rise of conductive liquid to a predetermined level in an auxiliary chamber communicating with a main chamber is detected so that an electric motor-driven pump is started to exhaust the main chamber and, by its operating pressure, causes expansion of a tube of resilient material against the internal wall of a cylinder to seal the remainder of the air in the auxiliary chamber so that the pump operates until the level in the main container falls to a low value. In Fig. 1, when the level of a conductive liquid, e.g. contaminated water, rises within auxiliary chamber 13 sufficiently to bridge electrodes 20, 21, an electrically driven pump is started to extract water from the main container (not shown). The operating pressure of the pump is effective at 3 to cause expansion of a thimbleshaped membrane of oil resistant rubber 102 against a sleeve 100 so as to seal the vent otherwise provided through sleeve 100 and channels 110, 111, 108. In consequence, the pump continues in operation until the level in the main container falls sufficiently to uncover an outlet in the lower part of chamber 13 (not shown) so that the level in chamber 13 can fall. Contours 104 are provided within sleeve 100 so that operation of the valve generates a self-cleaning action. Sleeve 10, which is sealed by 0-rings 118, is removable for inspection and cleaning. In a modification, the membrane is held in the lower part of sleeve 100 and is pushed over another sleeve projecting through the wall of chamber 13 so that both sleeve 100 and the membrane are removable from above. In this arrangement, the vent is completed through holes in sleeve 100 in an area experiencing further self-cleaning action. A float-operated switch may be used instead of electrodes 20, 21 to initiate operation of the pump, and the membrane may be a gas-filled envelope.

IPC: C08G65/32
Filed: 1957-12-23
Abstract: In the production of polyoxyalkylene compounds by condensation of an organic compound, having at least one hydroxyl, carboxyl mercapto or primary or secondary amino group, with one or more alkylene oxides in presence of alkali as catalyst, the "ash" content of the product i.e. the inorganic salt fomed by neutralizing the catalyst with acid, is reduced by addition of a lower alcohol or glycol to the crude reaction product to produce a precipitate which after standing and settling is filtered off. Alkylene oxides specified are ethylene, propylene, butylene, styrene, and cyclohexene oxides which should be free from aldehyde and water.  They may be added in admixture so as to form alkylene oxide units randomly distributed throughout the polymer chain. Alternatively, different oxides may be used in succession to give block polymers.  Sulphuric, phosphoric, hydrochloric or acetic acid may be used to neutralize the alkali. Lower alcohols or glycols which may be used are methanol, ethanol, propanol, butanol, ethylene or propylene glycol and are added in amounts of 3%-100% by weight of the reaction mixture.  In an Example (1): To a solution of potassium hydroxide in the monobutyl ether of ethylene glycol at 110 DEG C. were added successive charges of ethylene and propylene oxide.  The reaction mixture was neutralized with phosphoric acid and filtered and was found to contain 0,29% "ash."  The fluid was then homogenized with methanol and, after standing, a precipitate was formed which was filtered off.  The ash content of the polymer was then found to be 0,03%.  A table is given showing the reduction in ash obtained by using various alcohols and glycols.

[Also in Divisions G1 and G6] A device for transferring articles, e.g. balls 21, in discrete batches from a tubular input 6 to a tubular output 5 comprises a rotatable member 7 having radial tubular pockets 8, 9, 10, 11, 12, 13 into, and from which the batches of balls are moved under gas pressure when a pair of pockets are aligned with the input 6 and output 5, intermittent rotation of the member 7 placing succeeding pockets into alignment with the input and output. The intermittent motion is derived from a Geneva mechanism 17 secured to the member 7 which is rotatable in a housing 1. Passages 14, 15, 16 of reduced cross-section, connect radially opposed pairs of pockets to permit the passage of gas but not balls therethrough. In a modification, Fig. 3 (not shown), the rotatable member moves around a cylindrical core which is rotationally fixed and is provided with a gas passage to connect opposed pockets. This core is however axially displaceable to align a second passage in the core, with the opposed pockets, this second passage being of the same cross-section as the pockets to provide straight through passage for the balls when batching is not required.
