Patent GB-149805-A (GB)
Title: Improvements in carburetters for internal combustion engines
IPC: F02M7/17
Filed: 1919-06-02
Abstract: 149,805. Cozette, R. June 2, 1919. Spray carburettors.-The carburettor comprises a pilot nozzle d<1> supplying mixture directly to a mixing' chamber c, and a main nozzle f<1> which delivers into an annular chamber j communicating by holes i with a diffuser h open at the bottom to the atmosphere, the outlet from the diffuser h to the mixing-chamber c being controlled by a suction-actuated valve e. The valve e is provided with a hollow valve-rod k passing through the top of the chamber c and carrying a piston l working in a cylinder m which communicates with the atmosphere through an orifice n, and with the mixing chamber c by an orifice o. As the valve e starts to rise owing to the suction in the induction pipe, its movement is braked by the weight of the piston l and by the suction acting through the orifice o on the underside of the piston; when the piston rises sufficiently to cover the aperture n, the suction acts through the duct k' in the rod k on the upper side of the piston and the braking is diminished; upon a further rise of the piston, the orifice n uncovers the underside of the piston to the atmosphere, and the piston rises rapidly to the top of the chamber m.

Abstract: 1,189,289. Variable resistors. STACKPOLE CARBON CO. 18 March, 1969 [9 July, 1968], No. 14038/69. Heading H1S. A variable resistor comprises a housing 1 in which are disposed parallel collector and resistance strips 8, 9 interconnected by a sliding contact 7 which is operated by a cog 17 meshing with rack teeth formed in the edge of a slot 15 of an element 11 which extends over the length of the housing and is clipped on to the housing. The clipping is effected by the resilient legs (12, Figs. 1-3, not shown) of element 11 of metal, which embrace the ends of the housing. Projections 13 space element 11 from the housing, and the ends (22) of the slot are widened to allow insertion of cog 17 prior to clipping. Cog 17, of moulded plastics, has a spacer 19 to prevent removal of the cog from its spindle 18, which is integral with the contact frame 6. Alternatively, spindle 18 may be secured to cog 17 and rotably mounted in frame 6. Cog 17 may be turned by a knob 20, a thumb wheel (30) or a screwdriver, for example, inserted in a slot (31, Figs. 5, 6, not shown). Spacer 19 may have an integral pointer which co-operates with gradations adjacent the slot in element 11. Housing 1 is formed as two longitudinal halves of moulded plastics held together by a spring clip 2 or rivets.

Filed: 1956-05-07
Abstract: <PICT:0799908/III/1> <PICT:0799908/III/2> In a machine for making paper boxes, adhesive is applied to the upper surfaces of the box blanks B by means of an endless belt 213 which runs over two pairs of pulleys, a lower coaxial driven pair, one 160 of which causes the belt to make tangential contact with a roller 100 partially immersed in a reservoir 101 of adhesive situated to one side of and below the level of the blanks, while the other 161 brings the belt into contact with the blanks, and an upper coaxial pair 196, 197 above the first pair and at right angles to them so that there is a 90 degree twist in each vertical section of the belt.  The upper pulleys are mounted on a pivoted member 170 so that the tension of the belt may be adjusted by a screw 174.  The blank B is urged against the belt by the resilient fingers 241, 242.  The reservoir and applying mechanism may be moved transversely on the shaft 108 so as to apply a strip of adhesive at any desired location on the blank.

Title: Improvements in and relating to the production of cold worked reinforcement steel bars
IPC: C21D7/10
Filed: 1953-05-19
Abstract: 749,841. Altering physical structure of rods and bars. KAZINCZY, G. DE. May 19, 1953 [May 20, 1952], No. 14089/53. Drawings to Specification. Classes 83 (2) and 83 (4). A method for producing a cold-worked reinforcement steel bar for concrete structures comprises subjecting a single, hot-rolled bar in cold condition to one, or simultaneously or successively a plurality of working operations to permanently deform the bar and finally to a stretching operation with a force which causes greater stress than the stress at yield point of the hot-rolled material such that the permanent elongation due to this stretching is less than the elongation at yielding but that in steel qualities in which the said elongation is less than one per cent the permanent elongation shall not exceed one per cent. The main function of the first cold working operation is to raise the ultimate tensile strength of the bar and such first cold working may comprise twisting in one direction; twisting successively in opposite directions; bending repeatedly one or several times successively in opposite directions by passing the bar between one or a plurality of a series of rollers; stretching followed by twisting; bending followed by twisting; stretching followed by bending; cold rolling; cold rolling followed by twisting or bending to and fro the cold-rolling providing, if desired, ribs, cams or flanges on the bar. The last working operation, namely the stretching, is performed either immediately after the first cold working or later after cold or warm ageing of the steel resulting from the first cold working by which ageing both the elastic limit and the yield point are increased. The final stretching may be postponed until the bars can be tensioned during their mounting in the structural work.

Abstract: 560,644. Piezo-electric crystal mountings. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and TERRONI, T. B. D. Oct. 7, 1942, No. 14106. [Class 40 (v)] A shock-proof mounting for a circular or other piezo-electric crystal plate 1 having electrodes on its major surfaces comprises two rings 2, 3 of stainless steel formed with shoulders 4, 5 for engaging the crystal electrodes near the periphery.

Abstract: 639,057. Indicating-apparatus. COMMUNICATIONS PATENTS, Ltd., and MELMORE, R. W. May 30, 1947, No. 14426. [Class 106 (iv)] [Also in Groups XXIV and XL (c)] A mechanism for actuating and indicating the angular setting of a rotatable member comprises means for imparting coarse and means including epicyclic gearing for imparting fine angular movement to the said member, and coarse and fine indicating means movable in response to angular movement of the said member, the angular setting being indicated by a composite reading of the coarse and fine tuning means. As shown in Figs. 1 and 2, in a radio receiver the fine control knob 7 drives the spindle 15 through an epicyclic friction gear train contained in casing 16, the spindle 15 being coupled to the toothed driving wheel 28 through a friction coupling 30, 31 which enables coarse tuning to be used without involving operation of the epicyclic gear trains, and pins 29 projecting from the driving wheel 28 are attached to the member 8 which rotates the spindle 9 of the tuning condenser. The fine indicating scale 34 is in the form of a disc visible through an aperture in the plate 10 provided with a reference mark 37 and is driven with a step-up ratio from driving wheel 28. A cursor 36 is attached to the coarse control knob 6 which is rotatably mounted about the gear casing 16 and is provided with a rearwardly extending pin 27 attached to the driving wheel 28 to effect a direct drive to the condenser shaft 9. A single knob can be adapted for fine and coarse control by means of clutch mechanism. The outer end of the casing 16 of the epicyclic gearing, Figs. 4 and 5, provides a bearing for an intermediate shaft 17 of the gear train, the outer end of this shaft constituting a bearing for the input shaft 18 to which the "fine" control knob 7 is attached. At each end of the gear casing fixed conical surfaces 19 and 20 are provided and between these surfaces are arranged two axially slidable cone rings 21 and 22 forced apart by a compression spring 23. The cone surface 19 and cone ring 21 form bearing surfaces for three balls 24 maintained in radiallyextending apertures in the shaft 17, the cone 21 forcing the balls inwardly to co-operate with the shaped inner end of the shaft 18. Similarly, the surface 20 and cone ring 22 maintain the balls 25 contained in the shaft 15 in contact with the inner end 26 of the shaft 17, the two epicyclic gear trains constituting a two-stage speed reduction gearing.
