Title: An oil-pump and blower construction for heating systems
IPC: F23K5/14
Filed: 1969-10-17
Abstract: 1278994 Liquid fuel burners DANFOSS AS 17 Oct 1969 [6 Nov 1968] 51121/69 Heading F4T In an oil pump and blower arrangement for use in a heating system, the oil pump 2 and blower wheel 24 are driven by a common electric motor 1, both being mounted coaxially on the motor shaft 6, which has a central bore 9 serving as a discharge passage from a chamber 12 defined by the end face 27 of the pump housing 15 and an extension 13 in the motor housing 4. A toothed coupling 18 connects the pump shaft 17 to the motor shaft 6 to which the blower wheel 24 is also secured. A throttle passage 16 provides communication between the chamber 12 and the atmosphere. Oil which leaks from the pump into the chamber 12 is vaporized by the heat of the motor, and is entrained with a stream of air drawn in through the throttle passage 16 by the action of the blower wheel 24, which produces a reduced pressure at the end 10 of the bore 9. The mixture of oil and air passes through holes 22 in the coupling 18, along the bore 9 to the end 10, where it mixes with the air supplied by the blower to the combustion space.

Title: Glass-cermic laminated articles
IPC: C03B32/02
Filed: 1972-11-07
Abstract: 1380819 Glass-ceramic laminates CORNING GLASS WORKS 7 Nov 1972 [8 Nov 1971] 51206/72 Heading C1M A strengthened glass-ceramic laminated article comprises a glass-ceramic core of density D ef  and a compressively-stressed glass or glassceramic surface layer of density D sf  fused to and substantially enveloping the core, the core being formed by crystallization in situ of a crystallizable glass of density D ci  and the surface layer by crystallization of a glass of density D si , the core and surface materials being chosen such that the value of the expression is positive. The article is formed by laminating a thermally-crystallizable glass core portion and a glass or crystallizable glass surface layer at a temperature above the softening point of one of the glasses, and heat treating the laminated glass article at a temperature and for a time sufficient to crystallize the crystallizable glass portions, but insufficient to allow complete stress relaxation in the surface. The strengthening is primarily caused by differential densification on crystallization, but some strengthening may result from thermal expansion mismatch, as the core material preferably has an expansion coefficient at least equal to that of the surface layer before and after crystallization. Preferably the surface layer crystallizes at a lower temperature and higher viscosity than the core. Preferably the percent densification differential (D), defined by is at least 0À5%, more preferably 1-5%. Where the surface layer is of non-crystallizable glass or certain glass-ceramics D sf  = D si  (i.e. there is no density change in the surface layer).

Title: A Cathode Ray Tube having improved Life.
Inventor: BENDA DAVID
IPC: H01J9/395
Filed: 1967-11-17
Abstract: 1,194,357. Cathode-ray tubes. SYLVANIA ELECTRIC PRODUCTS Inc. 17 Nov., 1967 [17 Nov., 1966], No. 52388/67. Heading H1D. In a cathode-ray tube having an apertured metallic member such as the shadow-mask in a colour tube, the metallic member contains an occluded gas such as hydrogen or nitrogen which is continually released in operation of the tube under electron bombardment to maintain a partial pressure, e.g. 10<SP>-8</SP> torr, of the gas not more than one magnitude below the total pressure, e.g. 10<SP>-7</SP> torr. This is in order to maintain optimum electron emission and to improve tube life. The gas may be introduced from an external source before sealing of the tube or released from e.g. zirconium or titanium hydride contained within a ring structure also containing getter material, e.g. BaA1. The hydrogen is released first so that subsequent evaporation of the getter at a higher temperature secures a more uniform deposition of the getter on the metallic member and on adjacent parts of the envelope wall. Argon is usually present contributing to the total gas pressure.

In an asynchronous motor, with gradually variable speed, of the shorted type and with rotor feed, both the rotor and stator are rotatable, the motor having an annular magnetic circuit means fixed on the frame around the stator and arranged to be fed with gradually regulable direct current so as to create a regulable braking force on the stator, thus regulating at will the rotation of the main shaft; the revolutions per minute of the main shaft are thus the. difference between the revolutions per minute of the rotating magnetic field and the revolutions per minute of the stator. As shown, three rotor coils I to III in slots 6 in a rotor A, fixed to a shaft 1, are fed with three-phase A.C. through slip rings E. Around the rotor is a refutable " stator " cage B formed mainly by copper rods 8 shorted through the main rings 9 and provided with polar sectors 10 of magnetic material. Surrounding the " stator ", in turn, is a fixed magnetic ring C, having a coil F in slots 3 fed with D.C. As shown in Fig. 1, the D.C. is derived from a transformer and semi-conductor-rectifier circuit, and is controlled by a potentiometer P, so as to exert a variable braking action on " stator " B and thus vary the speed of shaft 1. Preferably the " stator " rotates on ball-bearings on shaft 1. The magnetic ring C may have internally-directed radial polar projections.

The coils are each wound using a conventional high speed coil winding machine, which may wind the coils successively, or alternatively, wind two diametrically-opposite coils simultaneously, and a looper 40, Fig. 4. The looper comprises a shank portion 41 and a shroud portion 42 with diametrically-opposed slots 44, 45, adjacent which are radially-projecting wings 46, 47 which have curved flanks 46b, 47b. Driving means (not shown) provides for both axial and rotary motion of the looper. In operation, Figs. 6(a)- 12(b) (not shown), a coil is first wound in two circumferentially-spaced slots using a flyer (60) and then connecting wires (16a)-(16g), Fig. 3 (not shown), between each coil are wound using rotary movements of the flyer and both rotary and axial movements of the looper (62), (63). The looper may be modified, Fig. 13 (not shown), to include a movable wedge-shaped section (130) lying adjacent slots 44, 45 and pivoted at a position (131). The section enables closure of radial clearance gap between the inner surface of the looper and outer surface of the commutator. A cam arrangement (not shown) effects radial movement of each section. After completing the coil winding, the connecting wires (16a)-(16g) are securely held in position on the armature prior to the fusing or staking of the wires to the commutator segments and the cropping of the loops from around the shaft 12.
