Title: Improvements relating to pallet loading apparatus
Inventor: DECOURCY ROLAND JOHN JAMES
IPC: B65G57/00
Filed: 1967-04-19
Abstract: 1,208,137. Loading pallets. DOUGLAS-ROWNSON Ltd. 7 June, 1968 [19 April, 1967], No. 18066/67. Addition to 1,068,718. Heading B8C. The apparatus described and claimed in the parent Specification is modified in that guides 7 (only one shown in Fig. 2) are provided adjacent both sides of the apron 2 for accurately locating corresponding edges of a layer of articles on the apron, and means are provided for sensing the arrival of a layer on the apron and for compacting the layer in the direction of apron-retraction. As shown, the compacting means comprises a roller 9 carried by a pivotally mounted beam 38, which may be lowered to the position shown so that the weight of the beam, acting through the roller, urges the layer against a second roller 8. Roller 8 is carried by a lever 21, which is pivoted at 22 and carries a roller 23, which engages a cam track 24. During machine operation, a layer, fed from rolls 1 to the apron 2, is halted by roll 8. This results in slight movement of lever 21, which closes a switch 28 to energize an electric motor 29. The motor then lowers the apron to the horizontal position shown through drive 30-36 and lowers beam 38 through chain 37. Guides 7, which may be flared at their upstream ends, are adjustable transversely of the apron, Figs. 3 and 4 (not shown). The articles may be crates provided with formations is for interlocking with the crates in adjacent layers on the pallets. Successive layers may be arranged in different patterns having the same overall shape so that each crate may interlock with at least two crates in adjacent layers.

Title: Improvements relating to the wet spinning of artificial filaments
Inventor: KENYON WILLIAM JOHNSON
IPC: D01D5/06
Filed: 1956-06-12
Abstract: <PICT:0808927/IV (a)/1> <PICT:0808927/IV (a)/2> In the wet spinning of artificial filaments, a spinning tube is used having a guide around which the filaments turn to emerge sideways from the tube, the guide being formed by the inner end of a slot extending along the tube from the discharge end.  The wall of the tube at the inner end of the slot may be indented so as to project into the tube interior to form a guiding surface, and the slot preferably runs longitudinally along the tube.  As shown, filaments 8 formed at jet 6 pass with the bath liquor through tube 1, emerge from slot 9 and are taken up by godet 10.  The inner end 11 of slot 9 forms the guide, which may be indented in the form of a transverse groove 12.  The flow of the bath liquor is promoted by maintaining different liquid levels on either side of bulkhead 3, which supports the tube. Specification 504,132, [Group IV], is referred to.

Title: Process for drying slime, particularly foul slime and plant for executing the said process
IPC: C02F11/13
Filed: 1951-07-31
Abstract: 709,131. Drying sludge. VON ROLL AKT.- GES., L. July 31, 1951 [Aug. 14, 1950], No. 18162/51. Class 34(2) In a process for drying sludge in an apparatus comprising a preheater 3, an evaporator 4, and a plate dryer 6, the sludge being fed from a storage container 1 by a pump 2 to the preheater, evaporator and dryer in succession, the vapours formed in the evaporator are fed directly, and the vapours formed in the plate dryer T are fed through a washer 14, to a compressor 10 whence they are forced as heating media into the evaporator and the plates 7 of the plate dryer, part of the condensate from the evaporator being fed to the preheater and thence as cooling media and lubricants to the stuffing boxes 10a, of the compressor, and the sludge moved by rotary means in the evaporator and the dryer, is divided into rodlets on one of the central plates of the dryer by a sieve 44. The diameter of the drying plates 7a is smaller than the internal diameter of the container 32, so that the sludge fed from the evaporator through a pipe 5 falls through the space 7b on to plate 7c which has a central aperture 7d for passage of the sludge so that the sludge passes from one plate to another moved by scraper 43 and dry material is discharged via shoot 8. The vapours heated by compression in the compressor 10 pass through pipe 11 into evaporator ring heating elements 4a and thence into tank 17 via pipe 11a, and also through pipe 12 into the hollow plates 7a, 7c and thence to tank 17, condensate from washer 14 also being collected in the tank 17 from which condensate is fed through pipe 16a to the heating element 37 of the preheater and to the washer 14. Condensate from chamber 3 is fed through pipe 18 to tank 19 and thence to stuffing boxes 10a by pump. 20. A water-ring pump 21 draws uncondensed gases and air from the outlet shoot 8.
Patent GB-292615-A (GB)
Filed: 1928-06-22
Abstract: 292,615. I. G. Farbenindustrie Akt.- Ges. June 23, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Aliphatic diamines, containing one secondary and one primary, secondary or tertiary amino group, are prepared by treating a secondary aromatic amine or nuclear-substitution derivative thereof with an aminoalkyl halide, and splitting off the aryl residue from the product. The amino substituent of .the secondary aromatic amine may be an alkyl, hydroxyalkyl or aminoalkyl group. The aminoalkyl halide may contain a tertiary aliphatic amino group, or a primary or secondary aliphatic amino group substituted by an aryl or arylidene group which is subsequently removed. The splitting off of the aryl residue may be effected by producing a p-nitroso compound or other compound containing a negative substituent, and decomposing the product to liberate the amine by means, for example, of alkali. The products are useful as drugs or as intermediates for the manufacture of drugs and dyestuffs. According to the examples (1) N-methyldiethylaminoethylaniline, obtained from monomethylaniline and diethylaminoethyl chloride, is treated in cold hydrochloric acid solution with sodium nitrite, and to the resulting nitroso compound sodium bisulphite solution is slowly run in; after standing some hours, caustic soda is added and the alpha-diethylamino-#-methylaminoethane distilled in steam; in an analogous manner as-triethylethylenediamine is obtained from N-ethyldiethylaminoethylaniline; (2) monomethylaniline is treated with alpha-dimethylamino-gamma-methylpropyl chloride and from the product, alpha-dimethylaminogamma-methylaminobutane is split off by the process of the preceding example; in the same way alpha-dimethylamino-#-methyl-gamma-methylaminobutane is split off from the product of reaction of monoethylaniline and alpha-dimetbylamino-#gamma-dimethylpropyl chloride, and a-diethylamino-#-diethylaminoethylaminoethane from the product of reaction of N-diethylaminoethylaniline and diethylaminoethyl chloride

A distributer for a pneumatic braking system having one or more sections comprises a valve assembly the drive element of which is connected at one end to the actuating pedal and at the other end to a shaped plug which is inserted between two guiding elements, at least one of which is pivotally mounted, to actuate the valves the axes of which lie in a plane which is normal to the longitudinal axis of the plug. Depression of pedal 18, Fig. 1, causes the conical head 32, of spring-loaded push rod 26, to move grooved roller 38, Fig. 2, away from grooved roller 36, the roller 38 being carried by a lever 48 pivoted at 50. A rocking lever 54, which is engaged by a spherical bearing 52 in the roller pivot 42, has its outer ends articulated to the ends of the valve stems 58 of valves A and B. Valve C, which is actuated by a cam 80 on lever 48, is identical with valves A and B. The mode of operation of valves A, B and C is known i.e. when intermediate chambers A 2 , B 2  and C 2  are communicant with chambers A 3 , B 3  and C 3  and consequently with atmosphere the communication between the intermediate chambers and compressed air source is closed and vice versa. Pressure switches A 4  and B 4  are operated to indicate any pressure loss and switch B 5 , actuated by either piston 64 or 65, indicates the brake application to a following vehicle. The valves may be operated simultaneously or successively either by varying the rates of springs 66 or providing rocking lever 54 with arms of different length. In another embodiment, Fig. 4 (not shown), the distributer has only one valve. In further embodiments, not described in detail, the distributer has two valves arranged adjacently horizontally or vertically or with the valves arranged oppositely with roller 36 attached to a rocking lever similar to lever 48.

Title: Method of tensioning a recording tape and recording tape transport apparatus therefor
IPC: G11B15/43
Filed: 1976-05-05
Abstract: 1536441 Maintaining constant tape tension BASF AG 5 May 1976 [6 May 1975] 18352/76 Heading G5R In a tape transport in which the tape is driven by engagement of a resiliently deformable periphery of a capstan 1 with the outer turn of tape on supply and take-up tape packs on shafts 6, 7 mounted on supports 4, 5 movable toward and away from the capstan 1, the supply pack is braked to generate a first component of the tension in the tape span between the tape packs and the take-up pack is urged against the capstan with a greater bias force than is the supply pack so that the difference in such biases produces a corresponding difference in the capstan periphery deformation at the two tape pack/capstan interfaces thereby generating a second component of said tape tension, the biasing and braking being automatically varied as a function of the supply pack diameter so that tape tension in said span remains substantially constant during tape transport The first tension component is at least equal to the second, the supply pack braking is such as to decrease with decreasing pack size so that the force to drive the supply pack at its periphery is substantially constant, and the pack biasing varies so that the deformation difference at said pack/capstan interfaces is substantially constant as the pack sizes vary during tape transport. Each shaft 6, 7 carries a respective braking/biasing means comprising a brake band 16 or 17 connected at one end to the transport chassis, wound around a brake drum 18 or 19, and connected at its other end to one end of a spring 20 or 21 the other end of which is connected to the movable support 4 or 5 or to chassis 2, Fig. 4b (not shown), the brake band portion between the chassis 2 and the brake drum 18 or 19 being parallel or at a varying angle to the direction of movement of the support 4 or 5. Supports 4, 5 are biased against capstan 1 by springs 15 extending between the supports 4, 5, together with varying biasing components produced by the springs 20, 21, the tensions in which increase and decrease as the corresponding tape pack size increases and decreases respectively. One-way clutch between the drums 18, 19 and shafts 6, 7 ensure that only the supply pack is braked with a force varying with the tension in the associated spring 20 or 21. The unidirectional clutches also cause the biasing tension in the brake band part between drum 18 or 19 and chassis 2 to be significantly reduced over the associated spring tension when the associated pack is the supply pack. The capstan periphery preferably has radial resiliency and circumferential rigidity. The capstan may comprise an elastic rubber coating around a rigid spool with one or more, e.g. five, layers of "Mylar" (Registered Trade Mark) splicing tape over the coating.

Filed: 1943-11-10
Abstract: 570,094. Thermionic relay circuits; code telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and STYLES, L. C. Nov. 10, 1943, No. 18708. [Classes 40 (iii) and 40 (v)] A thermionic switching arrangement comprises in series between the positive and negative terminals of a source, a hard vacuum valve and a gas filled valve, each grid controlled, together with means to apply potentials to both valves to render the gas-filled valve conductive and means including the hard vacuum, valve for rendering the gas-filled valve non- conductive. The Figure shows an arrangement in which the anode of the hard valve 1 is connected to the positive terminal and the cathode of the gas-filled valve 2 is connected to the negative terminal each connection including an impedance 3, 4. In this arrangement control is effected by applying negative spacing signals to the grid of the hard valve and positive marking signals to the grid of the grid controlled valve 2. As shown, the arrangement is applied to a telegraph relay system responsive to mark and space signals received over two different input terminals and is adapted to convert these signals to on-off signals in a single output channel. As shown, direct-current amplifiers 10, 11 precede the switching valves 1, 2. In this arrangement both mark and space signals are positive pulses, and phase reversing valve 12 is included in the marking channel. The output may be taken from the cathode resistance 4 in the form of positive pulses or from the resistance 3 in the form of negative pulses.

Title: Improvements in loop pile tufting machines
IPC: D05C15/22
Filed: 1959-06-02
Abstract: 871,852. Tufting machines. COBBLE BROS. MACHINERY CO. Ltd. June 2, 1959 [June 23, 1958], No. 18791/59. Class 112 In a tufting machine comprising a reciprocable needle 11 and a looptaking hook 18, the needle descends through a channel which extends to a point adjacent the hook, the channel being sufficiently narrow to prevent re-entry therein of a previously formed and spread loop, whereby the latter is held away from the path of the needle. As shown, the cloth plate 13 is provided with cloth-supporting fingers 14 which extend between the needles, the cloth plate being raised from the bed plate (not shown) by shims 16. A guard member 21, secured to plate 13 by screws which pass through the shims 16, is formed on its rear face 23 with vertical channels 24 each of which is aligned with a needle 11, and which is just wide enough to permit face passage of a needle and the yarn 19 carried thereby. The wall 23 is spaced less than a stitch length from the plane of the needle axes. The inner wall 26 of each channel is so positioned that, when the hook 18 moves anti-clockwise at the end of a loop-taking cycle, the corresponding movement thereby imparted to the entrained loop is arrested by wall 26, whereby the loop is first stretched and is then positively stripped from the hook. The released loop springs out of the channel and spreads out. It is thus unable to re-enter the channel into the path of the needle. It is stated that the arrangement is most suitable for loop lengths ranging from <SP>1</SP>/ 2  to <SP>7</SP>/ 8  inch.

Title: Improvements in or relating to the purification of coke oven gases and the like
IPC: C10K1/08
Filed: 1924-08-07
Abstract: The removal of hydrocarbons, such as benzene and toluene, from coke-oven and like gases is carried out by compressing the gases and passing them through a tower against a current of heavy oils, after which the last traces of hydrocarbons are removed by treatment with cresol in a second tower.ALSO:In a process in which partly purified coke-oven and like gases are treated with sulphuric acid for the removal of moisture and traces of ammonia and soda, a small quantity of a catalyst, such as tungstic or vanadic acid, may be added to the acid to cause absorption of part of the ethylene, which may thus be converted into alcohol.ALSO:Coke oven and like gases, the constituents of which are to to be separated by liquefaction, are given a preliminary purification in which solid and liquid impurities, hydrocarbons such as benzene and toluene, hydrogen sulphide, and the greater part of the carbon dioxide are removed by known methods, after which the removal of carbon dioxide is rendered complete by treating the gases with a solution of caustic soda containing glycerine; this treatment removes also any carbon oxysulphite that may be present.  Moisture and traces of ammonia and soda are then removed from the residual gases by treatment with sulphuric acid, and the gases may finally be passed through a vessel containing solid soda to remove traces of acid.  In the first stages of the process, in which known methods are employed, the hydrogen sulphide and the greater part of the carbon dioxide are removed by treatment with an ammoniacal solution, which may be regenerated or distilled and, after further treatment with water to remove ammonia, the gases are treated as described above for the complete removal of carbon dioxide and carbon oxysulphide, if present.
