Title: Improvements relating to electric signalling systems
IPC: G09F9/00
Filed: 1931-01-28
Abstract: 371,930. Electric signalling systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and CHRISTIAN, D. A., Morven, Charlton Road, Charlton, both in London. Jan. 28, 1931, No. 2803. [Class 40 (i).] In a system wherein apparatus, such as a stepping switch or relay chain for use in signalling, control, or telephone systems, is selectively set at a receiving point, some of the various settings of the receiver are determined by applying at the transmitter potentials to any one or a combination of line wires and others by connecting the line wires in series either directly or through a unilateral conducting device. In the arrangement shown a stepping switch RS is set selectively to operate a lamp in the group l1 .. l0, according to the conditions applied to the line wires a, b by keys K1 .. KO at the transmitting station. The keys are adapted to connect positive or negative potential to one or both of the line wires or to connect the wires in series either directly or through a rectifier d. In this manner the banks of wipers rs1 .. rs4 are marked according to the key operated and the switch RS hunts automatically until conditions are obtained over the banks to cause operation of a relay RR. The relay RR is such that it operates only when the currents in both windings are in the correct direction. The operation of the apparatus is initiated by a start key SK which when operated energizes relay S to close at sl a loop circuit over lines a, b which is subsequently opened by a slow-operating relay R which locks up over a release key RK and connects the line wires a, b to the keys. These operations transmit a starting impulse over the lines a, b and wipers rs1 .. rs4 and relay RR operates relay SR which operates stepping magnet RSDM over the normal contact in bank rs6. Interrupter springs rsdm are then operated and the switch is stepped on to the first contacts of the banks. Stepping then proceeds automatically over the commoned contacts of bank rs6 until conditions are applied to the line wires by the wipers rs1 .. rs4 which are complementary to those applied by the operated key. Relay RR then pulls up to prevent further stepping and operate the appropriate lamp over the wiper rs5. These conditions persist until another key or the release key RK is operated. The relay may be replaced by separate relays, the contacts of which are arranged in series to control relay SR. Moreover the stepping switch may be replaced by a chain of relays operated in cyclic order. In a modification, the keys control the application of potential to any one of four line wires or the connection of any pair in series. Each wire is connected to a wiper of the stepping switch, the banks of which are connected characteristicallv to a test relay. The switch at the receiver may be used for group selection, the switch being steered to a group as determined by the signals and mark group contacts in a searching switch or the steered switch may itself search for a free outlet.

Title: Improvements in and relating to apparatus for the production of fibrous cones
Inventor: EDNELL DANIEL FREDRIK
IPC: D21J3/00
Filed: 1953-02-04
Abstract: 731,552. Moulding cones front fibrous pulp. TEXTILE PAPER TUBE CO., Ltd. Dec. 28, 1953 [Feb. 4, 1953], No. 3203/53. Class 87 (2). Conical foraminous formers 4, Fig. 1, are coated with fibrous pulp in a tank 1 by suction through tube 8, and whilst they are being coated a reciprocating shaking motion is imparted to them to consolidate the coating and render it more uniform. Thus, a horizontal shaking motion is applied by an eccentric or crank to a frame 3 that carries the formers, and preferably the frame is also reciprocated vertically as by an eccentric 19<1>. The frame 3 then rises to insert the coated formers into conical cups 6 where the coatings are subjected to pressure and suction to remove water, the resultant pulp cones are transferred to the cups and the cups move leftward, Fig. 1, to transfer the cones to a conveyer 7. The cones may then be trimmed by cutters. Fig. 3 shows a former comprising a perforated cone 10 covered with wire mesh 12x. The cone is pressed against the flange of a cylinder 11 by means of a locking ring 13x secured to the wire mesh. The cylinder 11 is reciprocated horizontally by an eccentric or crank through the intermediary of an arm 17 and sleeve 16. Secured to the cylinder is a channel 15 forming part of frame 3, this channel having suction and pressure tubes 8, 9 connected thereto. Fig. 4 shows a cup 6 comprising a metallic sleeve 19 and a rubber lining 18. The sleeve 19 is connected to suction or pressure by conduit 23. When a coated former enters a cup the conduit 23 is connected to suction and the lining is sucked against the sleeve, whereby the former enters easily. The lining may be embossed or engraved, and may have projections to form a perforated cone. Resilient levers 25, pivoted at 25b and moved inward (as shown) or outward by a fluid-pressure piston 29, are provided to support the cones after they have been loosened from the cup 6. Sequence of operations:-(1) The coated former rises into the cup, suction still being applied through tube 8. (2) Pressure is applied to .the pulp through cup lining 18. (3)' The suction of (1) and the pressure of (2) are cut off, pressure is applied through pipe 9 to loosen the pulp on the former, and levers 25 move in to the position shown. (4) The former descends into the pulp bath. (5) The frame 5 with its cups (six of them) moves to a position over conveyer 7. (6) The levers 25 retract and suction is applied through conduit 23, whereby the cores fall on to the conveyer. Figs. 5 and 6 show a conveyer-cum-trimmer comprising a table 32 reciprocable on rods 33. The pulp cores are received on conical holders 35 which, when the table moves to the right, are rotated by the engagement of friction wheels 42 on their shafts with moving belts 43. As the table moves, a cam surface 44 pushes rotary disc trimming knives against the lower edges of the cores and then another cam surface 45 allows springs to retract the knives.

Title: Electrical resistors and methods of making them
IPC: H01B1/24
Filed: 1951-02-15
Abstract: 680,977. Resistance coatings and deposits. WESTERN ELECTRIC CO., Inc. Feb. 15, 1951 [July 7, 1950], No. 3683/51. Class 37. The resistor shown comprises a ceramic or other non-conductive and refractory base or core 1 having thereon a continuous layer 2 of boron and carbon which has been deposited in the presence of heat from a gas or mixture of gases containing boron and carbon. The Specification discusses at length the features and effects of various " cracking on " processes that may be employed in making such a resistor and shows how in repetitive batch manufacture coatings of differing resistivity, resistance/ temperature coefficient and boron content between 0.35 and 50 per cent by weight may bo formed according to choice of deposition temperature normally between 1000‹ C. and 1300‹ C., but under certain conditions outside this range, boron to carbon ratio in the gaseous mixture employed and the nature of the carbonaceous gas, the boron-containing gas and the diluent gas. In one specific manufacturing method described a fused silica bottle within a resistance heated furnace is loaded with ceramic cores to be coated, quartz particles and alumina balls. The loaded or charged bottle is then rotated whilst being continuously fed with a gaseous mixture of hydrogen, benzene vapour and boron trichloride vapour. If the coating period is one hour with the gas flow at 1000 c.c. per minute, the boron concentration in the total boron and carbon in the gas about 5 atomic per cent and the temperature 1100/1200‹ C., the process yields coatings having a boron content between 3 per cent and 4 per cent by weight. The quartz particles produce a burnishing action on the carbon-boron deposit and the alumina balls or pellets provide additional agitation of the cores. The Specification sets forth comprehensively the various gases that may be used to produce the carbon and boron deposits, including for the carbon, as additional to benzene, methane, ethane, propane, butane, toluene, xylene and carbon tetrachloride and for the boron a selected halogenated borine such as boron trichloride, already referred to, and phenyl dichloro borine. Helium or carbon monoxide may be used as the diluent gas although hydrogen is preferred. The non- conductive cores are preferably of the material disclosed in Specification 601,847, but bodies of glass, fused silica, quartz, ruby, sapphire or zircon may be used, also oxides such as silica, alumina, magnesia, calcium oxide, baria, strontia, titania, zirconia, lithia and sodium oxide.

Filed: 1920-02-06
Abstract: 162,811. Brush Electrical Engineering Co., Ltd., (Aktiebolaget Ljungstr÷ms Angturbin). Feb. 6, 1920. Securing turbine rotors on shafts.-To prevent loosening due to heat of a turbine rotor 3 on its tapered hollow driving-shaft 5, the shaft carries internally a tube 11 which carries a nut 13 bearing through a washer 14 against the rotor and against taper securing-keys 6 and at the other end is shouldered to engage the shaft and is prevented from turning by a screw 10<a>. The tube is under such tension that it pulls the rotor and keys further up the tapered shaft if the rotor expands. The nut 13 is locked by a pin 17 passed through a row of holes dissimilar in number in the shaft 5. To enable the nut 13 to be unscrewed for removal of the rotor, a bar is threaded through a screw 16 on the tube and bears on a closing-nut 15 at the other end of the tube, so that when further turned it puts additional tension on the tube and eases the pressure be tween the parts 3, 13. The nut 15 prevents steam getting to the connection between the shaft 5 and its driving-shaft 8.

Title: Rolling mills
IPC: B21B31/00
Filed: 1972-01-27
Abstract: 1385495 Rolling mills BRITISH STEEL CORP 24 Jan 1973 [27 Jan 1972] 3888/72 Heading B3M A cantilever rod rolling mill includes work rolls 20, 21 carried in individual arms 26 pivoted to each other by a pin 30 to form a sub-assembly which is removable from the mill. The work rolls are backed by rolls 22, 23 carried in pivotally mounted arms 37, the arms being adjustable by eccentric assemblies 100. To remove the sub-assembly from the mill, the backing rolls are moved apart after first releasing a screwdown ram and a pass-line wedge adjuster 87. An adjusting linkage for the pin 30 is disconnected, and a transverse bolt 56 (which retains the assembly axially in the mill frame) is withdrawn. The shafts 24, 25 of the work rolls can then be disengaged from their drive couplings and the assembly withdrawn to the left. The adjusting linkage serves to rotate the pin 30, Fig. 2, which has eccentric portions along its length. These portions co-operate with the two arms 26 in such a manner that rotation of the pin causes the arms to move axially in opposite directions, thereby allowing alignment of the two roll grooves. Each roll is held on its shaft by a hydraulic nut assembly 69. The linkage includes a lever 62, Fig. 1, a link 63, and screw adjusters 64. Loading units 80 and load cells (not shown) are located in the work roll chocks to measure tension in a workpiece being rolled. Further transducers, such as linear variable differential transformers, are associated with the chocks to indicate, and to allow control of, the gap between the rolls. Two such rolling mills may be close coupled in tandem for rolling rod or bar material.
