Abstract: 893,687. Fireproof sliding doors. EVANS LIFTS Ltd. Jan. 16, 1961 [Jan. 19, 1960], No. 1916/60. Class 20(3) A fireproof sliding door comprises overlapping panels 1-4 each composed of an asbestos core 5 enclosed in a sheet metal shell 6 and mounted in its own trackway. The vertical edges of each panel are provided on opposite sides thereof with hooked flanges 10 which interengage the flanges of adjacent panels when the door is closed. The door is opened and closed by actuation of a stepped arm 14 comprising three sets of two parallel rails 15 joined by cross members 16, which is pivotally mounted on a bracket 21 secured to door frame member 12 and engages grooved rollers 18 which slide in the channel formed between the parallel rails. The rollers are rotatably mounted in brackets 19 attached to the sliding panels. The doors are opened by pivoting arm 14 to its vertical position and the clockwise movement of the arm to close the doors is assisted by a weight 22 and spring buffer stop 24 secured to frame member 12. The door frame is formed by two metal angular members 12 to one of which the panel 1 is secured and the other is provided with metal strips 13 which form a channel to receive the outer margin of panel 4 when the door is closed.

Abstract: 346,479. Cooking-ovens ; doors for resisting fluid-pressure. JOHN, A. S., Stanton, Pembrey, Carmarthenshire. Jan. 21, 1930, No. 2153. [Class 126.] An oven of the type in which food is cooked under the pressure generated within it is provided with supporting devices at the bottom of the front which enable it to be tipped forward without removal from them, and which prevent lateral displacement of the oven, and also with rear bottom supports on which it rests in the normal position. In the oven shown the front supports comprise cylindrical lugs 12 grooved at 14 to engage in forked upright members fixed to or forming part of a supporting frame (not shown). The rear supports comprise lugs 11 with curved under-faces resting on corresponding curved members provided on the supporting frame. In order that the oven may be placed on the hot-plate of a gas-stove without the possibility of accidental movement the frame may be provided with bars which interlock with the hot-plate bars. The oven shown comprises a cylindrical body 1 closed at the front by a fluidtight door, and provided with a well 4 at the bottom for the reception of fat and with a receptacle 7 at the top for warming plates &c. A pressure-gauge 16 and a combined adjustable pressure relief valve and whistle alarm 17 of known kind are provided. The door 3 is removable, and is maintained closed by a four-armed spider having hooked ends 24g engaging tapered lugs 26b on the body and provided with a central knob 25 for rotating it to cause it to engage or disengage the tapered lugs. A fluid-tight joint is maintained by a packing ring engaging in corresponding grooves in the door and the end of the oven. The door may be hinged to the oven, and the spider may be pivotally mounted on the door. In the construction shown in Fig. 6, the boss 24 of the spider is carried on the threaded stem of the knob 25, which is attached to the door by a ball and socket joint 29.

Filed: 1969-01-14
Abstract: 1,223,222. Turbines. CARRIER CORP. Jan.14, 1969 [Feb.21, 1968], No.2228/69. Heading F1T. An inlet casing assembly for directing driving gas to a turbine rotor 42 comprises a support ring 10 having a cylindrical recess 16 within which is mounted with a small radial clearance the rim portion 26 of a hub member 22, the latter being attached to the rim 26 by three equi-spaced radial arms 24. The radial clearance is maintained by three set screws 20 extending through the support ring 10 to abut the rim 26, each screw 20 being positioned circumferentially midway between adjacent arms 24. Radial thermal expansion of the rim 26 relative to ring 10 is thus permitted. Axial movement of rim 26 is prevented by a diffuser ring 30 having a flange 32 screwed to a flange 13 on the ring 10 to thus urge rim 26 into contact with a shoulder 18 on ring 10. The hub 22 supports a guide vane ring 40. The ring 10 is supported from a casing 15 having coolant passages 19.

[Class 64 (ii).] In a method of permanent hair waving in which the heating of the coiled tress is effected by an exothermic chemical reaction, the tress being enclosed in an envelope or pad containing a suitable chemical such as calcium oxide which is moistened by water or other suitable reagent, the reaction is controlled by the addition to the chemical and/or the moistening medium of an acidic substance whereby the reaction is accelerated, or of a basic or neutral substance, whereby the reaction is retarded. Aluminium sulphate is specified as a suitable accelerating substance, and powdered starch or sugar, sand, ammonium and sodium hydroxide and substances which emit a volatile gas during the reaction, such as ammonium compound, as suitable retarding media ; when ammonium sulphate is used, it is found that the chemical is prevented from swelling and thereby bursting the pad or envelope. The chemical with its addition may be formed into easily friable cakes by means of a binder such as glycerin. Specifications 376,819, and 401,129, [Group XIV], are referred to. Reference has been directed by the Comptroller to Specification 225,256, [Class 131, Toilet &c.].

Abstract: 1408237 Fluid-pressure servomotor systems BAILEY METER CO 19 Jan 1973 [2 Feb 1972]  2931/73 Heading G3P [Also in Division F2]  In a timing apparatus 10, closure of a valve 26 by an input signal isolates a timing chamber 40 from a fluid supply 24 so that the timing chamber is evacuated through a vent 54 and a magnet 42 attracts a ferromagnetic flapper 58 to increase the pressure in a duct 68 and provide an output signal delayed with respect to the input signal. When the valve 26 is again opened, fluid flows into the chamber 40 to compress a spring 44 and, through a stem 46 raise a flapper 34 to decrease the pressure of the supply to the chamber until equilibrium is reached. The apparatus is now ready to receive another input signal. The spring may be adjusted by a screw 45 and the vent by a needle valve 52. The chamber containing the spring 44 may be connected to the inlet 24 and maintained at constant pressure.

Abstract: 1,246,016. Speed controlling. GEARAIDE Ltd. 17 April, 1970 [17 Jan., 1969], No. 2937/69. Headings B3B. B3C and B3T. [Also in Divisions G3 and H2] A machine tool spindle drive, e.g. for a lathe or drilling and boring machine, comprises a direct current motor driving the spindle and a speed controlling arrangement that includes a plurality of thyristor control devices TC1-TC4 and a selector device for determining which thyristor control device is to be operative at any given time. The individual control devices are adjustable in infinitely small steps. The control of the spindle speed through the thyristor control devices and D.C. motor ensure substantially constant torque over the complete speed range. The selector device may comprise a peg board, or automatic control of the machine through punched tape may determine a required speed. The speed of rotation of the spindle may be varied with the feed of a crossslide to provide constant cutting speed by providing a potentiometer in the control circuit which is operated as the cross-slide moves. A load may be applied in the circuit of the motor to provide dynamic braking. This can be used to stop the spindle in a particular angular position. A thyristor control device is selected to produce a low spindle speed prior to stopping the spindle in its required angular position. A conventional gear driven lathe may be modified to the present control arrangement by providing a D.C. motor and fixing the gears in a selected gear.
