Title: Improvements in and relating to the manufacture of electric lamps
IPC: H01J9/30
Filed: 1952-06-26
Abstract: 720,422. Dynamo - electric apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. June 26, 1952 [June 30, 1951], No. 16113/52. Class 35. [Also in Group XI] Apparatus for threading a leading-in wire into a vertical perforation in the end of a lamp cap comprises means for holding a lamp bulb upright with the leading-in wire substantially vertical, means for locating the cap in alignment over the bulb, and means for agitating the cap both vertically and laterally while thus located in order to provide repeated opportunities for the wire to enter the perforation. The apparatus is preferably located at one of the work-stations adjacent to an indexing- conveyer of the endless-chain type provided with a series of pairs of bulb-holding jaws, each of which holds a bulb vertically with the neck uppermost (see Group XI). The cap is of the kind comprising a screw-threaded metal shell with its upper end closed by a web of insulating material such as glass with a metal eyelet located within it to form a central end contact. Below the eyelet the glass web is recessed to a conical shape to facilitate the threading of the leading-wire through the aperture. In one arrangement, Fig. 6, the agitation of the cap within a threading-tube is effected by magnetic induction, the threading- tube being made in the form of a soft iron yoke 91 with three inwardly facing wire-wound poles 88-90 to which 3-phase A.C. is applied, thereby developing a rotating magnetic field and generating eddy currents within the cap, so that it is caused to vibrate and rotate; its rate of descent is also retarded. In a modification, Fig. 7, a threading tube 99 is resiliently mounted on a base by means of flexible spring fingers 100, 101 and an armature 103 attached to the threading tube is vibrated by an electromagnet 102, the system being arranged to be mechanically resonant at a frequency close to that of the energizing current of the magnet. The threading tube is slotted vertically at equidistant intervals and flexible snubber wires or springs 105 are located in the slots, their upper ends being fixed to the interior of the tube immediately above the slots.

Title: Improvements in and relating to the manufacture of abrasive tools
IPC: B24D18/00
Filed: 1943-10-04
Abstract: In the manufacture of abrasive tools, such as wheels, drills and cutters, a mould is wholly or in part lined or coated with an abrasive powder which may be mixed with bonding material, and is then filled to the desired level with metal which is melted or made plastic under reduced atmospheric pressure or in a reducing or neutral atmosphere, so that the metal when cold has one or more faces having embedded abrasive.  The abrasive material is preferably diamond either alone or mixed with other abrasive such as aluminium oxide.  Heating is by high-frequency induction, frequencies of from 470,000 to 15,000,000 cycles being employed. The higher the frequency the shorter the time of heating and the greater the temperature that may be employed without destroying the diamonds, particularly if the atmosphere be reducing or neutral.  A highly refractory mould lined with zirconia is employed, and the abrasive face is located outside the inductive field.  The abrading material may be powdered steel or other metal and when the added metal is melted it permeates the pores in the bonded abrasive without disturbing the abrasive or melting the bond.

Title: Improvements in or relating to the Treatment of Hydrocarbon Oils
Inventor: FOWLER RAY
IPC: C10G65/12
Filed: 1967-04-11
Abstract: 1,153,650. Hydrodesulphurization and hydrodealkylation. POWER-GAS CORP. Ltd. 9 April, 1968 [11 April, 1967], No. 16501/67. Heading C5E. A hydrocarbon oil feedstock, e.g. the byproduct of the thermal cracking of naphtha into ethylene and propylene, containing organic sulphur compounds of the thiophene type and/ or olefines and diolefines is reacted with hydrogen or a hydrogen-rich gas in the presence of a catalyst, e.g. a molybdate of cobalt or nickel, at a temperature not exceeding 420‹ C. and at an elevated pressure to convert olefines and diolefines and organic sulphur compounds to paraffin hydrocarbons and hydrogen sulphide respectively, and the product is reacted, together with further hydrogen if necessary, at a temperature exceeding 520‹ C. and at an elevated pressure to hydrodealkylate aromatic compounds. If the feedstock contains a substantial proportion of diolefines it can be first reacted in the liquid phase at up to 200‹ C. with hydrogen using a catalyst containing nickel to convert the diolefines to olefines. The dealkylation is carried out non-catalytically at 650-790‹ C. or using a catalyst containing a molybdate of nickel or cobalt at 540-590‹ C. The formation of carbon during the dealkylation reaction may be inhibited by the addition of steam. The hydrodealkylated product is cooled and separated into a gas containing methane, ethane, hydrogen and hydrogen sulphide and a liquid containing the aromatic product and water. The aromatic product, e.g. 94À4% benzene, 4À3% toluene, and 1À3% xylene with 3 ppm of sulphur compounds, may be fractionally distilled to yield benzene and a toluene-xylene mixture which can be recycled to the hydrodealkylation reaction.

Title: Improvements in or relating to the cleaning of bottles, jars or the like containers
IPC: B08B9/28
Filed: 1937-06-15
Abstract: 496,254. Washing bottles. HILL ENGINEERING CO. (HULL), Ltd., T., HILL, T. E., and HARRISON, N. C. June 15, 1937, No. 16534. [Class 138 (i)] In a bottle-washing machine of the conveyer type, a detector and trip mechanism is arranged at the loading station for arresting the machine if a closed or stoppered bottle is fed to it. The foremost of a row of bottles 12-14 supplied by hand to each of a series of troughs 10 is raised by a ram 15 until its neck engages and raises a centring cup 20 which is slidable along a peg 24. The pegs are slidable through a fixed bar 26 and engage, at their upper ends, a pivoted bar 27. If a stoppered bottle engages a peg, the bar 27 is rocked to actuate trip mechanism 30-34 associated with a draw-bar 35 arranged between the starting handle and clutch of the machine. If the bottle neck is open, it slides over the peg without moving it. The bottles are raised along fixed guides 36 and pivoted guides 37. After the detecting operation, the guides 37 are turned to horizontal position, Fig. 5, to align the bottles with further pivoted guides 41. Pushers 38 force the bottles from the guides 37 to the guides 41, while the latter are horizontal, and the guides 41 are then swung down, Fig. 1, to position the bottles, with their necks in centring cups 44, in line with rinsing jets 43. After rinsing, the guides 41 are returned to the horizontal, and the bottles are forced by rams 47 into cups 48 on a conveyer which carries them to the washing stations. After washing, the bottles are delivered to a slat conveyer 52, for carriage to a filling or drying station, by pushers 50, pivoted guides 51, and pushers 53. A trip mechanism may be arranged at this point for stopping the machine if a bottle is not delivered to a guide 51. The rams 15 are actuated by counterweighted levers 16 freely mounted on a rock-shaft 17 carrying a bar 19 which supports the levers. The rock-shaft is rocked to an extent required by the smallest bottle to be handled, the bottles, whatever their length, being arrested by the cups 20. The centring cups 44 are pivoted to the guides 41 and are turned to horizontal position, by cams 42, when the guides 41 are horizontal. Bottles may be fed to the rams 15 from a slat conveyer. The trip mechanism 30-34 may be duplicated so that an operator must use both hands to restart the machine. Specification 466,484 is referred to.

Title: Improvements in or relating to multi-channel signal transmission systems
IPC: H04J1/04
Filed: 1937-06-16
Abstract: 474,021. Multiplex systems. SIEMENS & HALSKE AKT.-GES. June 16, 1937, No. 16756. Convention date, June 18, 1936. [Class 40 (iv)] In a multiplex system employing two modulation stages, the first carrier frequency being the same for all the channels, and one side band being filtered out after each modulation, the carrier frequencies are so chosen in relation to each other and to the width of the speech bands that the upper and lower side bands resulting from the second modulation form two substantially continuous bands with a gap between them, so that the final filtering operation can be performed by a single filter for all the channels. In Fig. 1, the speech signals, which are limited to the range 0-3 kc. by filters AF1-3, modulate a carrier S, for example 6 kc. in modulators M11-13 and the lower side bands are eliminated by filters BF1-3. These bands within the range 6-9 kc. entermodulators M21-23 which are supplied with different carriers T1-3, for example 27, 30, 33 kc. The combined outputs ‹ comprise lower side bands 18-21, 21-24, 24-27 7 kc. and upper side bands 33-36, 36-39, 39-42 kc., and the lower side bands are eliminated bv a high-pass or band-pass filter GF (see Figs. 2, 3). The general conditions for this result are that S must be an integral multiple of the original band width a and that T1, 2, 3 ... must be consecutive integral multiples of a. If there are a considerable number of channels, they may be divided into several groups each of which share a common filter GF. Moreover two neighbouring groups may be arranged to share a single band-pass filter GF, which selects the upper side bands of the lower frequency group and the lower side bands of the upper frequency group (see Fig. 5).

Abstract: 640,372. Embossing-surfaces. SEMPERIT GUMMIWERKE AKT.-GES. June 25, 1947, No. 16775. Convention date, July 28, 1941. [Class 100 (ii)] A process for the after-treatment of dies stamped from artificial material, which may chiefly consist of fibres impregnated with artificial resins, and which show a rough surface interspersed with minute pores at the blank portions, which therefore, when the dies are used for stamping printing formes out of plastic materials such as rubber, firmly adhere to the plastic mass so as to be difficult to separate therefrom, consists in closing the pores by applying pieces of fibrous fabrics impregnated with artificial resins to the blank portions and hot-stamping. Where the dies are composed of several fibrous fabrics, the pieces applied may be pieces of the material used to form the dies, and where the fabrics composing the die comprise several layers, a similar layer may be used. When the layer is in place, a flat stamping means, such as a smooth piece of sheet-iron, is applied and the assembly compressed to a predetermined height. When the die is withdrawn from the press, the blanks present smooth uniform surfaces.
