Title: Improvements in and relating to wireless systems for use in navigation
IPC: G01S1/02
Filed: 1929-06-28
Abstract: 335,967. Graham Amplion, Ltd., Sinclair, D., Hodgson, A. D'A., and Rickets, W. J. June 28, 1929. Bearings and distances, determining; signalling to aircraft.-For navigating aircraft &c., two parallel beams of electromagnetic radiation are projected along the course to be followed. In one modification the transmitters are at either end of the course, substantially coincident, and of identical wavelength, but modulated at different audio-frequencies. The indicator on the aircraft or other vehicle may be actuated by a goniometer showing divergences from the course, and may consist of vibrating reeds, tuned telephones or lamps connected to a suitable resonating system, in each case tuned to the audio-frequencies in use at the transmitter, or may be a galvanometer influenced by rectified currents. The relative indications of the two indicators serve to indicate the relative distance of the craft from the two ends of the course. The distance travelled may also be estimated by the interference effects of the beams which occur at equally spaced points along the course. Alternatively the beams may be of slightly different wavelengths and the indicator responsive to the heterodyne note. In another form, the two transmitters project beams lying side by side along the course, and the relative indications of two indicators on the craft serve to show veering from the centre of the course. Alternatively the two beams may overlap to give a zone where heterodyne effects occur and a third indicator, responsive to these, installed on the craft. The two beams may be directed from the same or opposite ends of the course, and may be slightly divergent. In a further modification, a gap may be left between two parallel beams. According to the Provisional Specification a single beam may define the course. Specifications 13924/01, 21247/01, [both in Class 97, Philosophical instruments], 19878/06, 313,926, 317,006, 329,812, and 336,643, are referred tu.

Patent GB-801021-A (GB)
Title: Improvements in or relating to the cutting of strips of wrapped articles
IPC: B65B57/20
Filed: 1956-06-27
Abstract: 801,021. Cutting-apparatus. WETZEL, E. June 27, 1956 [Feb. 17, 1956], No. 19920/56. Class 31(1). [Also in Group XVII] Apparatus for cutting from a strip of wrapped articles, e.g. tablets, produced continuously by a wrapping machine, unit lengths containing a predetermined number of such articles, comprises cutters past which the strip is fed to a counter whose rate of counting is proportional to the rate of feed of the strip and which is adapted to actuate electrical means controlling actuation of the cutters at regular intervals in its counting operation, the counter including an adjustable setting control which determines the period of said intervals. The counter is preferably of the type which may be set to count up to a predetermined number and then back to zero, the electrical means, e.g. a solenoid, being actuated by closure of a switch when the counter records zero or the predetermined number. The rate of counting is preferably such that the number set on the counter corresponds to the number of articles in each unit length cut from the strip. The counter may also be arranged to count the number of unit lengths cut from the strip. The electrical means may actuate the cutters directly or may be arranged to disable a latch which normally prevents mechanical actuation of the cutters. As shown, the strip 1 is fed downwardly between cutters 2 which are mounted on levers 9, 16 pivoted on axes 10, 15 and interconnected by a tension spring 11. Arms 18, 19 on the levers are coupled by a link 17 so that clockwise movement of the lever 9 produces an anticlockwise movement of the lever 16. The lever 9 carries a follower 12 engageable with a cam 13 on a shaft 3 which is driven from the wrapping machine. The counter 6 is driven from the shaft 3 by chain and sprocket gearing 4, 5 and 20 and controls a switch in the circuit of a solenoid 7 which is coupled to a spring-loaded latch 8 engaging the lower end of the lever 9. When the switch is closed, the solenoid withdraws the latch 8 and the follower 12 is allowed to enter one of a series of recesses 14 in the cam 13 so that the cutters are operated by the spring 11.

Title: Tools for cutting
IPC: B23D21/10
Filed: 1973-04-26
Abstract: 1458366 Shearing; portable tools Z BIEGANSKI 21 March 1974 [26 April 1973 6 Aug 1973] 19923/73 and 37165/73 Headings B3W and B3T [Also in Division H2] A tool for cutting a tubular workpiece such as a cable sheath comprises frame portions 10, 12 hinged at 13 and held to form a closed loop by a releasable catch 22,and a cutter unit 48 mounted in a handle 36 for radial movement relative to the loop and angular adjustment about the axis of radial movement. The cutter unit 48 comprises a support 80, in which a cutter 50 is mounted, which rests on a plug 60 and has a forked end which embraces a pin 58 projecting through the holder wall. The shaft 80 extends through the handle 36, the upper end 34 of the handle being held in a selected angular position relative to a frame portion 32 by spring-loaded detents 42. Threaded on the handle 36 is a sleeve 56 angularly fast with a knurled sleeve 66. A spring 64 urges the plug 60 radially inwards of the loop to an extent determined by engagement of a head 70 on a pin 62 with the end 68 of the sleeve 56. The other end of the sleeve 56 engages the pin 58, so that rotation of the sleeve 66 moves the cutter unit into and out of the loop, the pin running in slots 54 in the handle 36. Rollers 90 are mounted on a bracket 88 threaded on the support 80 for rotation with, or relative to, that shaft. Cable support rollers 14, 16 are mounted in the frame. For making a circumferential or helical cut the handle 36 is in the Fig. 2 position; for making a longitudinal cut the handle is turned through 90 degrees from the Fig. 2 position. With the cutter advanced to penetrate the sheath the device is rotated about or drawn along the cable respectively for circumferential/ helical and longitudinal cuts, by means of the handle. To prevent inadvertent rotation of the sleeve 56 the sleeve 66 can be moved axially relative to it so that a spring-loaded ball 76 engages the more remote from the cutter of tworecesses in the sleeve 66 when the pin 58 will engage in the castellated end 78 of the sleeve 66. The cutter unit 48 can be replaced, e.g. by a wheel cutter unit, Fig. 3 (not shown). In an alternative embodiment, Fig. 4, a cutter holder (112), Fig. 5 (not shown), urged into the loop by a spring (118) carries a pin (114) movable by means of a knob 116, in a gate slot comprising two spaced aligned portions 102 and 104 connected respectively to a parallel portion 110 by transverse portions 108 and 106 to accommodate cables of different diameters. The holder is retracted until the pin is at the base of the selected slot and the cable inserted; the spring (118) then urges the cutter to penetrate the sheath.

Title: Improvements in automatic door locking devices
IPC: E05C5/00
Filed: 1920-07-09
Abstract: 147,911. Dorneth, J. July 9, 1920. Catches, gravity; multiple fastenings; keyholes, obstructing. - A heavy sleeve is adapted, when released from a supporting-pawl e, to fall and turn, as the result of the movement in a camgroove c of a pin d on the door-frame, so as to bring arms b into engagement with catches g on the door. The fastening can be released by raising the sleeve, either directly from the inside of the door, or by a lever h which is key-operated from the outside. When raised, the sleeve is held up by the pawl e, which is not disturbed upon opening the door, a lever q on the door riding idly over an inclined lug m upon the pawl piece. Upon closing the door, the nose of the lever q takes under, and raises the lug m, releasing the pawl, and allowing the sleeve to fall. The provision of a second lug n renders the fastening applicable to doors of either hand. A camplate t is movable into the position shown in dotted lines, when it raises the lock to disturb the alinement of the keyhole with the lock mechanism, and also holds the trip-lever q out of action.

Title: Improvements relating to electrical pulse generators
Inventor: SCOLES GRAHAM JOHN
IPC: H02K39/00
Filed: 1957-06-25
Abstract: 888,293. Electric generators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 16, 1958 [June 25, 1957], No. 19989/57. Class 35. An electrical pulse generator comprises in the embodiment shown rotor and stator members, a plurality of conductors 5 mounted on one of the members to form one or more armature windings, the other member including one or more C-shaped field cores 1 located adjacent the armature windings and carrying one or more field windings 2, the angle subtended at the rotor axis by each pair of adjacent armature winding conductors 5 substantially equalling the corresponding angle subtended by the span of each field core, and means whereby electrical connections may be made to the armature windings, the arrangement being such that if the field windings are excited by intermittent pulses amplified pulses will be obtained from the armature windings. The output energy is obtained from that stored in the mass of the rotor member and not from the input to the field winding which merely determines the output waveform. Such input may be from a condenser or a pulse forming network, not shown, which may produce half-sine wave pulses which saturate the field to create a square magnetic field waveform. Preferably the armature windings are on the rotor members and the field windings are on the stator member. In another embodiment, not shown, the rotor member is a disc carrying radial conductors interconnected to form U-shaped armature windings from which the output is taken via slip-rings or spark gaps.

Title: Improvements in or relating to desulfurization of petroleum coke
IPC: C10L9/08
Filed: 1951-08-24
Abstract: 690,791. Desulphurizing coke. STANDARD OIL DEVELOPMENT CO. Aug. 24, 1951 [Nov. 13, 1950], No, 20024/51. Classes 50 and 55(i) A process for removing sulphur from petroleum coke comprises heating the coke and holding it at a high temperature for a set period, the coke being passed downwardly in the form of a moving bed through a desulphurization zone which is divided into three sections, a top heating section 1, a soaking section 3 and a bottom cooling section 5. The sulphur-containing coke is charged through a duct 2 into section 1 where it is preheated by hot combustion gases from section 3. The hot coke then passes into section 3 where it is further heated to about 2700‹F by the combustion of preheated fuel gas, such as methane or natural gas in preheated air which enters through a line 8 from a preheating furnace 9. The coke remains in section 3 for 6-20 hours depending on its initial sulphur content and the amount by which this is to be reduced. It is then moved down into the cooling section 5 into the bottom of which the fuel gas is admitted through a pipe 7. The coke is cooled and the gas, which is thus heated, passes up into section 3, the cool coke, with a reduced content of sulphur, being extracted through a duct 6.

Title: New triazine derivatives
Inventor: BIRTWELL STANLEY
Filed: 1954-07-09
Abstract: The invention comprises triazine derivatives of the formula <FORM:0767749/IV(b)/1> wherein R stands for an anilino radical the phenyl radical of which may optionally bear substituents or for a phenylguanidino radical, the phenyl radical of which may optionally bear halogeno substituents, A stands for a hydrocarbon linking group and R1 and R2 stand for hydrogen or for alkyl radicals or they are united to form, together with the adjacent nitrogen atom, a heterocyclic ring.  Compounds of that formula where R stands for an anilino radical, the phenyl radical of which may optionally bear substituents, are obtained by heating a biguanide of the formula R-C(: NH)-NH-C(: NH)-NHANR1R2 with an acylating derivative of trichloracetic acid.  Suitable derivatives are the anhydride, acid chloride or esters.  The process may be effected in a solvent or diluent such as trichloracetic acid. Compounds of the above formula where R represents a phenyl guanidino radical, the phenyl radical of which may optionally bear halogen substituents, are obtained by heating a compound of the formula <FORM:0767749/IV(b)/2> wherein R3 stands for a phenyl radical which may optionally bear halogeno substituents with a compound of the formula H2N.A.NR1R2, suitably in the presence of a solvent such as benzene.  In Example (1) N1-p-chlorophenyl -N5-g -dimethylaminopropylbiguanide is heated in a mixture of trichloracetic acid and anhydride to form 2-p-chloroanilino-4-g -dimethylaminopropylamino - 6 - trichloromethyl - 1 : 3 : 5 - triazines.  Similarly prepared are 6-trichloromethyl-1 : 3 : 5-triazines having as 2- and 4-substituents respectively (2) 3 : 4-dichloroanilino and g -dimethylaminopropylamino, (3) p-chloroanilino and b -dimethylaminoethylamino, (4) p-methoxyanilino and g -dimethylaminopropylamino, (5) anilino and g -dimethylaminopropylamino, (6) p-chloroanilino and b -piperidinoethylamino and (7) p-nitroanilino and g -dimethylaminopropylamino groups.  In Example (8) 2 - p - chlorophenylguanidino - 4 : 6 - bis-trichloromethyl - 1 : 3 : 5 - triazine (obtained by reacting 2 : 4 : 6-tristrichloromethyl-1 : 3 : 5-triazine with p-chlorophenylguanidine) is heated with g -dimethylaminopropylamine to form 2 - p - chlorophenylguanidino - 4 - (g  - dimethylaminopropylamino) - 6 - trichloromethyl - 1 : 3 : 5-triazine.  2-p-Chlorophenylguanidino-4-(d  - diethylamino - a  - methylbutylamino) - 6 - trichloromethyl - 1 : 3 : 5 - triazine hydrochloride is similarly prepared.

Title: Improvements relating to rolling seal diaphragms
IPC: F16J3/02
Filed: 1963-05-22
Abstract: 1,015,339. Piston packings. J. F. TAPLIN. May 22, 1963 [Dec. 28, 1962], No. 20351/63. Heading F2T. A rolling seal diaphragm for a piston-andcylinder assembly comprises a fabric element 10, Fig. 6, having corrugations, crinkles or waves in the circumferential threads, yarns or cords 49 in zones with no bias in the axial direction of the diaphragm to allow circumferential extension in these zones whilst the zones are substantially free from axial stretch. The diaphragm is manufactured by placing a deformable die 12 more readily circumferentially compressible in at least one zone 16 than in at least another 14 against a fabric blank 10 more readily circumferentially compressible in at least one zone 30 than in at least another 32 with the more readily circumferentially compressible zone of one overlying the less readily circumferentially compressible zone of the other and vice versa, and simultaneously circumferentially compressing both by drawing them between male and female drawing dies while confining them in a thickness direction to prevent any doubling up on itself of the fabric of the blank. The more readily circumferentially compressible zones 16, 30 of the blank 10 and die 12 occur where the threads are at a bias to the radial direction and the less readily circumferentially compressible zones 14, 32 occur where the warp or fill threads are tangential to the circumference of the blank and die. The zones 14 of the die may be rendered substantially incompressible circumferentially by coating the threads and filling the interstices between them with cured rubber material. The blank and die are placed in the female die 20 and covered by a slip plate 24 during deformation by the male die 26, the clearance between the male and female dies being less than three times the thickness of the stack comprising the blank 10 and die 12. The stack may consist of a die 12 between two blanks 10. After drawing, the fabric blank is set, for example, by heat and the use of an impregnant, such as starch, and then separated from the die 12. A layer of elastomer 42 is then applied to the fabric as described in Specification 855,348. Finally, the base 48 of the diaphragm is trimmed and holes as required punched in the base and head 46.
