Title: Fuel burner and combination thereof with a fire tube boiler
IPC: F23D11/00
Filed: 1965-04-02
Abstract: 1,106,106. Induced draught, return tube boilers; burners. LANDON KINGSWAY Ltd. 2 April, 1965, No. 14180/65. Headings F4A, F4B and F4T. A return tube boiler is provided with a cylindrical combustion chamber 10 into which a gas or oil burner 40, fires the combustion products after reversal in compartment 15 passing back through the banks of return firetubes 20 to discharge compartment 25 where they are exhausted to atmosphere through a constant volume induced draught fan 34 which serves to draw air into the combustion chamber through ports 54 in the burner 40. The motor 36 of the fan 34 also operates pump 37 to supply oil under pressure to the burner 40. Elongate cross-sectioned fire tubes (Fig. 3, not shown) having an internal cross-sectional area in square inches to external circumference in inches ratio of between 1 : 3 and 1 : 8 are used. Alternatively cylindrical tubes may be used. A baffle 23 in the water space prevents surging on filling. In the burner 40 a frusto-conical air directing shell 50 is located downstream of the nozzle 45. The shell 50 is provided with circumferentially spaced inclined air slots 52 and edge control ports 56. Deflecting vanes 53 at the sides of the slots 52 promote whirling of the air as it meets the conically expanding stream of fuel from the nozzle 45.

Abstract: 689,848. Feeding articles in predetermined attitude. KORK-N-SEAL, Ltd. June 8, 1951 [June 8, 1950], No. 14286/50. Class 117 [Also in Group XXX] In a means for feeding bottle caps and like articles of dished or cup-like shape having flanged rims the articles are fed through spaced rollers 21, 22, by the arrangement described in Specification 689,846, [Group XXX], and are delivered by an endless belt 35 to a shoot 48 formed by guide plates 50, 51, back plate 52, curved upward extension 53 of the plate 51, oscillating block 54, and adjustable side plate 56. The parallel plates 50, 51, have vertical edges 76 spaced from the back plate 52 a sufficient distance to take the rim of a cap 70, and have curved guide surfaces 79, the upper end of the vertical edge being inclined away from the back plate for a short distance and then extending downwards to merge into the curved edge 79. The block 54 is oscillated by means of a crank arm 93 and carriers an arcuate member 94 which allows the caps to drop one at a time over the guide plates 50, 51, caps 70 having their rims against the back plate 52 falling straight down to the delivery throat 84, and caps having their rims disposed in the opposite direction, as at 86, sliding down the plates 50, 51, with their rims running over the curved surfaces 79 whereby the disposition of the caps is changed from the vertical to horizontal. These caps then fall on to the shoot 180, turn about their points of initial contact with the shoot, and slide down to the delivery throat in the correct position,

Abstract: 185,805. Pessell, R. C. Feb. 14, 1922. Teaching signalling; .code signalling mechanism; semaphore and lamp signals. - Apparatus for sending any predetermined message in code without the need for the operator to know the message comprises a movable arm associated with a slotted member adapted to be engaged by projections on plates carried adjustably on radial slots formed in a rotating wheel, the movable arm transmitting its movements to signalling members. In the form described, a signalling arm 2, preferably removable, is pivoted at 3 and adapted to be moved by an arm 7 through a pen-and-slot connection 11, 12. Attached to the arm 7 is a member 17 slotted as shown at 18, 19, 20. A number of plates 23 are carried in slots in the rim of a drum 21 mounted removably on the casing 10 and adapted to be rotated by the rubber rimmed wheel 35 turned by a handle 38. The plates 23 are held by a spring band 27 in one of the notches a, b, c so that one of the projections 24 engages one of the slots 18, 19, 2'0 to move the arm 2 to give dots or dashes. The drum 21 is kept running true by a pin 48, 49, which projects into the groove 26. Movement of the arm 7 also closes a contact at 41, 42 to give buzzer or lamp signals on both. Specincation 132,630 is referred to.

IPC: B21D28/22
Filed: 1953-05-22
Abstract: 774,894. Punching; making toothed gearing. BIRMINGHAM STOPPER & CYCLE COMPONENTS CO., Ltd. Aug. 17, 1954 [May 22, 1953], No. 14424/53. Classes 83 (2) and 83 (4). A detachable work - holding and indexing device for adapting a punching press to punch notches in a circular blank, e.g. to form the teeth of a bicycle chain wheel, comprises a carrier secured within the frame of the press below the working bed, a shaft journalled in the carrier, passing through the working bed and supporting at its upper end a work-holder,- and fluid-pressure operated mechanism for rotating the workholder step-by-step in time with the movement of the press ram. A cam 38 secured on the crank-shaft 4 of the press actuates a valve 35 controlling the supply of oil to a cylinder 34. During the upward stroke of the punch 3, the piston in the cylinder 34 is returned by springs 32 to cause a pawl 42 to step a toothed wheel 10 on the shaft 6 carrying the work-holder 9. The power stroke of the piston actuates a finger 30 which locks the toothed wheel 10 while each notch is punched. The press is started by a pedal-operated clutch, and when the shaft 6 has turned through a complete revolution a projection thereon operates a valve 47 which disengages the clutch to stop the press. The gearblank is clamped on the work-holder 9 by a rotatable disc 15 supported on arms 16 pivotally mounted on the working bed 1. A handle 24 supported on the bed 1 operates a crank to raise or lower the clamping disc 15. A rod 48 connected to the arms 16 prevents engagement of the clutch when the clamping disc 15 is raised. The exhaust oil from the cylinder 34 is sprayed on to the tool to act as a lubricant.

Title: Improvements in and relating to a.c. measuring instruments
IPC: G01R15/00
Filed: 1949-05-30
Abstract: 665,183. Voltmeters. WILKINS, S. R., ATTWOOD, W. H., and AUTOMATIC COIL WINDER & ELECTRICAL EQUIPMENT CO., Ltd. June 22, 1950 [May 30, 1949], No. 14515/49. Class 37. The usual single diode rectifier in a multirange A.C. measuring instrument, as described, for example, in Specification 608,187, is replaced by a twin diode, a proportion of the contact potential of one diode inverted being used to off-set the contact potential of the other or signal diode to such an extent as to leave the desired forward voltage deflection of the order of 0.07 to 0.09 volts for the purpose of linearizing the scale shape at all ranges. As shown in Fig. 1, the signal diode A and the balancing diode B of a twin diode are inverted relatively to one another. A potentiometer 11 is connected across the balancing diode B and the contact thereon is connected into the D.C. potential divider chain 12, 13 in the anode circuit of the diode A at a point 14 where no R.F. is present, and only the D.C. output of the signal diode A appears. In a modification, Fig. 2, the inverted contact potential output from the balancing diode B is injected through a high resistance 20 into the D.C. potential divider 21, 22, 23 which feeds the D.C. volts from the signal diode A into a valve multivoltmeter V1, V2. The resistance 20 is such that the contact potentials from the diodes A, B are approximately balanced at the point X. Final balancing to allow for differential contact potential variations between the diodes A, B is achieved by feeding a small D.C. voltage relative to the zero signal point Y into the potential divider chain at the point X through a very high resistance 24. A potentiometer C is connected across the potential divider chain 25 at points which include the point at which the triode V2 is connected to the potential divider 25.

Abstract: Lubricating-compositions especially for use under high pressures consist of a lubricating oil to which is added or is caused to be produced therein, an oil-soluble complex compound formed between an inorganic or an organic metal compound free from unsubstituted hydrocarbon radicals, and an alkyl or aryl compound of an element of groups 5 and 6, right-hand column, of the periodic system, or esters or acids of these elements.  Suitable compounds for the first component of the complex are, cuprous chloride, bromide or iodide; cupro-rhodamide; silver azide or chloride; cupro-acetylacetone; nickel oleate; cadmium butyrate; stannic or antimony chloride; and for the second component are, dibutyl sulphide, selenide or telluride; tri-ethyl or propyl phosphine or phosphite; trimethyl amine; triethyl arsenite; amylcetyl- or di-octyl-sulphide; diethyl ether, or butyl mercaptan.  Some of these also act as anti-oxidants.
