Title: Improvements in or relating to gas calorimeters
IPC: G01N25/42
Filed: 1921-04-07
Abstract: 183,408. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). April 7, 1921. Calorimeters.- In 'a continuous-flow gas calorimeter, the burner and associated parts are so constructed that the stream of fluid which absorbs the heat of combustion is made to flow, after such heat absorption, in heat-exchanging relation with the same stream before or during the absorption of heat. Further, the products of combustion are made to flow in heat-exchanging relation with the combustible mixture so as to pre-heat the latter. The Figure shows the burner which is employed in a calorimeter having the general construction described in Specifications 153,817 and 182,573. A mixture of gas and air passes up the tube 21 and additional air for combustion up the tube 20. The products of combustion are deflected downwards by a tube 31 having a closed upper end and pass around the burner. The air which absorbs the heat of combustion is introduced through a conduit 33 and passes up through a tube 32 surrounding the tube 31, to the lower end of which it is hermetically sealed. The upper end of the tube 32 is surrounded by a cap 34 having a closed upper end so that the stream of air after being heated is deflected downwards around the upper part of the tube 32. Resistance thermometers 7, 8 included in a wheatstone-bridge circuit are subjected to the initial and final temperatures of the stream of air.

Title: Injection molding apparatus with leakage preventing means
IPC: B29C45/23
Filed: 1949-05-23
Abstract: 670,039. Injection - moulding machines. TRIGGS, W. W. (Fellows Gear Shaper Co.). May 23, 1949, No. 13669/49. Class 87(ii) Molten material is injected from a heating chamber 10 through a nozzle by a plunger 13. During an injection stroke, a resilient diaphragm 25 is moved off a rib 28 by the pressure of the material to allow the material to flow through a space 27, aligned holes 30, 31, Fig. 6, in a flange 22 and in the diaphragm, and a bore 20 in the nozzle. At the end of an injection stroke, the diaphragm moves back on to the rib 28, due to its resilence, to prevent leakage of material. The rib 28 projects beyond the plane of the diaphragm clamping surface 26, to give the diaphragm an initial tension. The holes in. the flange and the diaphragm are aligned by a dowel 32, Fig. 6. To prevent leakage between the end of the heating chamber and a cap 15, a ring 34 is placed in a groove formed partly in the end of the chamber and partly in the cap 15. The ring also aligns the nozzle with the chamber. The end face of a block 16 is bevelled away from the surface 35 on the end of the chamber, to obtain a tighter closure between the chamber and the block.

Title: Production of carbon and graphite fibres
IPC: D01F9/32
Filed: 1972-07-26
Abstract: 1442321 Carbon fibres KOPPERS CO Inc 26 Oct 1973 [26 July 1972] 13755/72 Heading C1A Carbon fibres are obtained from an aromatic distillate of coal tar by contacting the distillate with elemental oxygen at an elevated temperature until at least 0À5 standard cubic feet of oxygen is consumed per pound of distillate, the distillate being converted into a pitch-like substance which will yield isotropic carbon when carbonized at above 800‹ C., forming the pitch into fibres and carbonizing the fibres at a temperature above 800‹ C. The aromatic distillate preferably has a boiling range of 200- 400‹ C., and air may be used as a gas containing elemental oxygen. The contacting step may be performed at 250-420‹ C. under pressure, e.g. 80 to 100 p.s.i., sufficient to prevent vapourization. After treatment with oxygen, the pitchlike product may be distilled so that its softening point after distillation is 100-200‹ C. The pitch maybe extruded at a temperature 50‹ C. aboveits softening point. After extrusion the fibres may be treated with air at a temperature of from 130- 150‹ C. to harden the fibre-this is preferably done during extrusion. The isotropic fibres have the following analysis by weight: C-93À0 to 97À0%;H-0À2 to 0À6%; O-2À5 to 4À0%; S-less than 0À6%; N-less than 0À2%. The fibres so produced may be graphitized.

Title: Improvements in or relating to Machines for Covering Wires and other Cores with Yarn and the like.
Inventor: STOTT NORMAN
IPC: D02G3/36
Filed: 1918-08-24
Abstract: 131,461. Stott, N. Aug. 24, 1918. Wire and cores, covering by winding. - Relates (1) to an arrangement of variable-speed friction drive for the haul-off pulley or drum and (2) to an arrangement of inverted covering-head, in machines having two or more heads, whereby the one or more inverted heads can be driven by the same gear as the complementary upright heads. (1) The covering-heads a, b, Fig. 1, and the haul-off pulley c are all driven from a shaft d, which is driven by a friction wheel g through a friction disk h splined on the shaft. The pulley c is driven from the shaft d through a friction wheel 10 on the shaft and a friction disk 11 on one end of a shaft 12. the other end of which is provided with a worm 13 engaging a worm-wheel 14 on the pulley shaft 15. The friction wheel 10 is splined on the shaft d, and is adjustable transversely of the face of the friction disk 11 by means of a screw plug 20 and a rod located coaxially with the friction wheel 10 in a bore in the shaft d, against and under the action of a spring tending to force the friction wheel towards the periphery of the friction disk.

Patent GB-354356-A (GB)
Title: Improvements in or relating to yielding or resilient couplings for rotating bodies
IPC: F16D3/62
Filed: 1930-05-06
Abstract: 354,356. Securing toothed wheels on shafts. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A., and SMALL, C. J. P., Bush House, Aldwych, London. May 6, 1930, No. 13854. [Class 80 (ii).] A brake such as a centrifugal friction governor for regulating the speed of a weight, spring or electric motor driving sound recording or reproducing machines of the disc, cylinder, photographic film, or magnetic wire or tape variety, is driven through a resilient coupling the stiffness of which increases with relative displacement of the two coupled members. A disc type induction motor 11 drives directly a spindle 10 on the top of which is mounted a phonograph turntable. The governor comprises bob weights 17 on leaf springs 16 operating a movable flange 19 engaging a fixed or adjustable friction pad 20. The driving worm wheel 13 of the governor is fixed to a coupling member 30 free on the spindle and co-operating with a coupling member 25 fixed on the spindle, the members 25, 30 each having two opposed, nearly semicylindrical recesses housing balls 32 of considerably less radius of curvature than the recesses. The members carry flanges and are drawn together by tension springs 37. One of the flanges 34 is circumferentially adjustable by screw-and-slot means 35, whereby when the drive is in one direction only, the springs may be given an initial inclination so that normal torque is transmitted resiliently largely bv the springs alone. The balls then remain substantially inactive in the bottoms of the recesses, and the resilience is sufficient to absorb irregularities in the governor and its worm gear. With increase in load the balls ride up the recesses and greatly increase the resistance thereby preventing excessive displacement.

Abstract: 858,707. Electrical analogue calculating circuits. LEVI, R. May 2, 1957 [May 12, 1956], No. 14025/57. Class 37 An analogue computor for solving distribution problems, such as the distribution of similar articles between a plurality of production centres J and consumption centres K with a minimum of transport with T K J, comprises a first set of conductors in pairs each pair V n  An (Fig. 2) corresponding to a production centre and a second set of conductors in pairs each pair V m a m  corresponding to a consumption centre the bars intersecting one another as shown in Fig. 1. Each bar An is connected to a rheostat E n  set at a conductance corresponding to P<SP>J</SP> the number of articles available at a production centre while each bar am is connected to a rheostat F m  set at a conductance C K  required at a consumption area. At each area of intersection c<SP>n</SP> m  the bars V m , V n  are so-interconnected that current dependent on excess of demand over supply, can only flow from V m  to V n  due to rectifier 1, any such current engergizing relay Rn m  to close contact 4, a variable voltage representing transport with T<SP>J</SP> K  being set in by a transformer 2, rectified and opposing any voltage difference between vm and Vm. A rectifier 6 connected between bars An, am ensures that current (representing the number of articles sent from the production to the consumption centre) flows only from An to a m  provided switch 4 is closed. i.e. that a potential difference between v m  and Vm and therefore an excess of demand over supply exists. The operation is as follows, the quantities pJ and c K  are first set in and the potential on v m  is increased until the reading on voltmeter G is zero indicating that the demand is being met by the number of articles sent from the production centre, this procedure being repeated for each area of intersection. The an reading on ammeter Hn will indicate whether the resources of the production centre are fully utilized, when said reading will be zero or whether the centre is overproducing when there will be a certain reading.
