Patent GB-205899-A (GB)
Title: Improvements in or relating to protective arrangements for alternating electric current circuits
IPC: H02H7/26
Filed: 1922-07-27
Abstract: 205,899. Reyrolle & Co., Ltd., A., and Biles, R. W. July 27, 1922. Protective arrangements.-In alternating current parallel conductor systems, each conductor is paired with each of the other conductors by cross-connected secondary windings or balanced primary windings of current transformers, a relay being provided for each of such paired circuits and operating on disturbance of balance to control gaps in a tripping circuit, a fault in one conductor causing the operation of two relays to cut out the faulty conductor only. As shown in Fig. 1, applied to three parallel conductors A, B,. C with circuit-breakers A<1> B<1>, C<1>, the operating windings of relays D, E, F are connected across equipotential points of cross-connected secondaries of paired conductors and each winding serves to operate a double bridging contact-member D<1>, D<2>, E<1>, E<2> and F<1>, F<2> to bridge the gaps A<3>, B<3>, A<4>, C<4>, C<3>, B<4> in the tripping circuits A<2>, B<2>, C<2> of the circuit-breakers. If, for example, a fault develops on the feeder A, the relay winding D causes the bridging of the gaps A<3>, B<3> and winding E that of the gaps A<4>, C<4>. The two gaps B<3>, A<4> are in the tripping circuit of the circuit-breaker A<1> which consequently opens; the other gaps B<3>, C<4> are bridged ineffectually as a second gap B<4>, C<3> respectively remains open in the tripping circuits of each of the other two circuit-breakers. When the faulty feeder is cut out, the system is still effective to cut out both the remaining feeders in the event of a fault on either of them. Specifications 27090/12 and 27660/13 are referred to.
Patent GB-148774-A (GB)
Title: Improvements in reversing mechanism more particularly applicable to washing machines
IPC: D06F37/36
Filed: 1920-07-10
Abstract: 148,774. Apex Electrical Manufacturing Co., (Assignees of Orr, W. V.). June 10, 1918, [Convention date]. Washing-machines with closed or enclosed rotary receptacles.-In automatic reversing-gear, the movement of the clutch lever 56 for changing the direction of drive to the shaft 6 from the motor-driven shaft 8 is effected, after a definite number of revolutions, by means of a series of rings 45 loosely mounted upon the hub 22 of the driving-wheel 20. Each ring has a lug 46 with a pin 47 projecting over an adjacent ring into the orbit of its lug and the first ring is driven by a pin 52 on the wheel-hub 22 while the last ring has an arm 49 slotted at 50 to engage a pin 57 on the clutch lever 56. Reversal takes place therefore when the rings have all been picked up successively by the drive, and the number of rings used determines the number of revolutions between reversals. The clutch-lever movements are rendered rapid and complete by means of a spring- encircled telescopic link 61 pivoted to the gearcase at 62 in line with the lever 56 in its mid position. To stop the machine, a slotted arm 69 is moved by a handle 68 so as to embrace a pin 66 on a secondary clutch lever 65 and bring this lever with the clutch spool 33 to a central or neutral position. In order to reduce the strains of reversal on the motor a lost-motion drive is introduced between the bevel pinion 25 and its shaft 26, thus allowing the driven shaft 6 to slow down somewhat before reversal. A wringing- machine may be mounted upon the washing- machine and be driven from the shaft 8.
Patent GB-775824-A (GB)
Title: Method and apparatus for the supply of hydrocarbon charge to moving mass hydrocarbonconversion processes
IPC: B01J8/12
Filed: 1955-07-15
Abstract: In a continuous process for the conversion of fluid hydrocarbons in the presence of a downwardly moving, compact reaction bed of granular contact material, a stream of hot contact material at a temperature to effect the conversion passes down a conduit 16 (Fig. 1) to a reaction bed 31 confined at the top by a member 18 shaped as a hollow frustum of a cone.  The contact material expands outwardly between member 18 and a conical baffle which is in two parts 21 and 22, so that a layer 33 is formed having a cross-sectional area, normal to the direction of flow, which is a minor fraction of the horizontal cross-sectional area of the reaction bed 31.  The <PICT:0775824/III/1> hydrocarbon charge at a temperature below that of the contact material and preferably as a mixture of liquid and vapour, is fed by a pipe 27, through a manifold 25 to a series of feed pipes 29 extending radially outwardly and so spaced that lines drawn through the centres of the outlet ends of adjacent pipes and extending outwardly parallel to member 18 intersect walls 10 of the chamber at points horizontally spaced apart less than 20 inches.  The velocity of hydrocarbons issuing from pipes 29 is maintained sufficiently high so that bubbles 34 are formed in which vapour, liquid and catalyst are thoroughly mixed and arrive at a uniform temperature.  The majority of the contact material supplied to the reaction bed passes through bubbles 34.  The product of the conversion is removed by a pipe 35 and the contact material is removed by a pipe 12.  Two modifications of the apparatus (not shown) are described.  The conversion may be the catalytic conversion of high boiling hydrocarbons to lower boiling, gasoline-containing hydrocarbons, using a catalyst as contact material.  The conversion may also be catalytic dehydrogenation, polymerization, isomerization, or alkylation using an adsorbed catalytic solid, or thermal coking, cracking or visbreaking using granular inert material.

Title: Improvements in or relating to electric motors
IPC: H02K25/00
Filed: 1927-08-05
Abstract: 298,722. Williams, B. G. Aug. 5, 1927. Motors with unwound iron armatures; electromagnets.-In a small motor for gramophones, fans or other use of the type in which the rotor is moved by the intermittent creation of neutralizing fields, a star-shaped iron armature is employed in combination with two electromagnetically equal field windings arranged in a plane parallel to the armature, one winding being controlled for example by means of a commutator,. so that it successively augments and neutralizes the field of the other. In the form shown, a stellate iron armature R, Figs. 3 and 4, rotates above groups of magnets 1 - - 4 which are successively magnetized and neutralized by means of a commutator C driven by worm gearing 14 from the shaft 11 of the turntable 10. Each bobbin has two windings, shown in Fig. 1 in full and chain-dotted lines A, B respectively, one set of which, A, is permanently connected in series across the line. The winding B in alternate groups of bobbins is reversed and connected to the mains through the commutator C in such a way that in the position shown the two windings co-operate magnetically in the groups of magnets 1 and 3 and annul each other in the groups 2 and 4. The arms R', R<3>, Fig. 4, are accordingly attracted by the groups of magnets 1, 3. The consequent rotation of the commutator then reverses the current in the windings B and the arms R<2>, R<4> are attracted by the magnets 2, 4 and the action is repeated continuously thereafter. The magnet rows are placed irregularly with respect to the symmetrical armature (at 75‹ and 105‹ apart in the form shown), whereby the possibility of the armature being at any time at a " dead centre. " position is avoided. By rocking the brushes on the commutator, the time of beginning the pull by the energized magnets may be controlled and the speed thereby varied. The two windings A, B may be wound simultaneously or in a superposed manner on the bobbins, or, as shown in Fig. 5, one winding B may be sandwiched concentrically between two layers of the other one A. The invention is applicable to continuous or alternating-current motors and to those in which the magnets rotate and the armature is fixed in place of the converse arrangement shown.

Title: Improvements in or relating to the examination and trimming of printed photographs
IPC: G03D15/04
Filed: 1945-08-13
Abstract: 626,451. Trimming photographs. BARKER, W. G. Aug. 13, 1945, No. 20741. [Class 31 (i)] [Also in Group XVI] Photographs 1 are cut from a continuous strip of photographs such as are described in Specification 611,910, [Group XX], by means of a stamping press having a cutting-out tool which cuts out the photograph and delivers it to a drawer, and the strip is fed step-by-step to the press by means acting in synchronizm with it. The strip is fed from a roll 2 over a table 6, where it is examined for defects, and rolls 10 guide the strip to a continuously driven pin-wheel 41 against which the strip is pressed by a roller 42 carried by pivoted arms 43. The pins on wheel 41 engage holes 8 in the strip, and from the wheel 41 the strip passes to a reciprocating pin feed comprising a reciprocating pivoted carrier 20 formed with pins 7 which are adapted to engage the holes 8 as the carrier 20 moves to the right and to be freed therefrom on return. The carrier 20 is pivoted to a shaft 21 which is reciprocated in a slot 22 by means of a crank 27 and connecting-rod 28 driven from the main drive shaft of the press. The strip 1 passes under guides 30, 31 which are slotted so as to permit passage of the pins 7 but not a shoulder 34 which carries the pins, thus causing the pins 7 to move in a straight path while feeding. On the return stroke the carrier 20 is freed from the strip by the action of an extension 29 of the connecting-rod 28 upon a screw 35 secured to one arm of the carrier. The strip is registered for the cutting operation by means of pins 18a carried by a flange 14 on the plunger which engage the apertures 8 in the strip while the cutting action occurs. The strip is clamped in position by a spring-pressed clamp 15 which engages the work after it is registered and before it is cut.

Abstract: 831,416. Hop harvesters. KIBINGER, F., and EDER, H. June 30, 1958 [June 28, 1957 ; March 8, 1958], No. 20908/58. Class 6(3). Apparatus for separating hops from their branches comprises one or more movably mounted cutting tools 15 shielded by gratings 6 arranged to prevent the hops from being damaged by the cutters. The cutters 15 are carried by shafts 10 supported rotatably in spaced discs 1, 4, each shaft 10 preferably carrying several cutters 15 each associated with a grating 6 consisting of two wires 8, 9 provided with deflecting rods 11 and joined at their ends to stays 3 which rigidly connect the discs 1, 4. Each of the discs 1, 4 is mounted on a bearing 2<SP>1</SP> rotatable on a fixed shaft 2, and the unit formed by members 1, 3 and 4 may be rotated manually by a crank drive or by a motor through gears, chain or belt drive. Each alternate shaft 10 carries rigidly either an upper pulley 16 or a lower pulley 16<SP>1</SP>, and all but two of shafts 10 also carry rotatably guide rollers 17 or 17<SP>1</SP> respectively. A pair of endless belts 19, 19<SP>1</SP> are wound round the pulleys and guide rollers, as shown, and round pulleys 18, 18<SP>1</SP> respectively which are rigid on the shaft 2. When the unit formed by members 1, 3 and 4 is rotated all shafts 10 will rotate in the same direction. The shafts 10 may be driven through gear wheels and an endless chain. Rods 20 on the shafts 10 stop the mechanism from becoming clogged. Branches carrying hops, which are fed into the chamber bounded by the gratings 6, are thrown outwards by centrifugal force so that the cutters 15 sever the hops, all the severed material then passing out between the gratings 6 against the inner wall of a stationary hopper (not shown), which surrounds the rotary mechanism, and down through an opening in the lower end of the hopper to a sorting mechanism. A cylindrical cover (not shown) encloses the area between discs 1 and 4 ; and shaft 2 has a conical cover 5. The cutters 15 may have saw blades.
