Title: Improvements in and relating to thermosensitive devices and apparatus incorporating the same
IPC: H05B3/56
Filed: 1950-05-01
Abstract: 696,369. Supply systems for consumption apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. May 1, 1950 [May 4, 1949; May 4, 1949 ; Dec. 15, 1949], No. 10668/50. Class 38 (iv). [Also in Group XXXVI] A system for operating an indicating or controlling device in response to an abnormal rise in temperature in a load comprises a sensitive device in the form of a flexible cable (see Group XXXVI), including a conductor forming the load (e.g. the heater wire of a blanket or a winding of an electric machine) and a second conductor, the conductors being bridged by an organic material which is normally non- conductive and of low permittivity but the conductivity and permittivity of which increase with temperature. Protected heating systems for blankets. The current for the heater 11 is controlled by an adjustable thermal interrupter 26 external to the blanket. The system is switched on by a momentary operation of button 32 to connect the supply to a bridge formed by resistors 30, 31, inductor 29 and protective signal wire 14 in series with capacitor 28 which forms a resonant circuit with the inductor. In these conditions a relay 25 connected as a diagonal of the bridge pulls up and completes the supply circuit to the blanket, the supply to the bridge being maintained and resistor 35 being included in the capacitive arm after button 32 is released. A neon indicator 42 glows to show that the blanket is "on". If the blanket is overheated, the resulting change in the sensitive material lowers the impedance between wires 37, 38 and 40 and upsets the tuning of the circuit 28, 29 the current through 25 is reduced and the relay drops out. Deliberate switching off is effected by momentarily short-circuiting 25 by a button 45. Any circuit failure releases 25 by destroying the tuning of 28, 29 to the supply frequency. Specification 619,797, [Group XXXVI], is referred to.

Title: Method of concentrating latex by evaporation
IPC: C08C1/12
Filed: 1956-04-09
Abstract: <PICT:0806877/III/1> In a continuous process for the evaporation of water from natural or synthetic latex, a pool of latex 2 of the desired final concentration is maintained in the base of the evaporator 1 from which latex is continuously withdrawn through pipe 4, part of this concentrated latex being discharged from the system as product through pipe 10 while the remainder is passed through heat-exchanger 8 and mixed with dilute latex supplied through pipe 12, the mixture being then introduced in finely-divided form into the evaporator where water evaporates from the droplets as they fall down to the pool.  The process reduces foaming and loss of latex, by entrainment in the vapour, to a minimum.  The two streams of latex are mixed in the device 11 which contains a perforated plate 13 arranged to break up the streams into fine droplets and to ensure thorough mixing.  The vapour leaving the evaporator through take-off 14 is passed through trap 15, and condensed in condenser 16.  Any entrained latex is caught in trap 15, and returned to the latex pool through pipe 17.  An example relates to the concentration latex made from butadiene-styrene copolymer.  The latex in pool 2 contains 60 per cent solids; the recirculated latex is heated to about 165 DEG F. in heat-exchanger 8; and latex containing 40 per cent solids, at a temperature of 120 DEG  F., is added through pipe 12, the volume-ratio of concentrated to dilute latex being about 4 to 1.  The mixed latex contains about 57-58 per cent solids.  The pressure in the evaporator is maintained at 40 to 66 mm. Hg. absolute by a steamjet vacuum system (not shown).  All the latex-recirculation pipes are enamel-lined; and the vessels are lined with an epoxy resin coating composition.

Title: Improvements in or relating to floating roofs for bulk storage vessels and method of constructing a floating roof
IPC: B65D88/34
Filed: 1946-04-08
Abstract: 610,294. Fluid-storage tanks. CHICAGO BRIDGE & IRON CO. April 8, 1946, No. 10740. Convention date, Oct. 16, 1945. [Classes 54 and 69 (i)] A double-deck float 20 for a fluidstorage tank is built up of a number of concentric sections so secured together as to form an undersurface 22 which slopes upwardly from the rim 23 to the centre of the float. This float is constructed on the tank bottom 41, which has a correspondingly shaped surface to that of the float and one of the annular sections between the inner and outermost sections is left untrussed so that if there occurs above the float an excessive water load, which the normal drain 27 is unable to cope with, then the roof may sag and cause lowering of the intakes of the emergency drains 28 which then operate. To facilitate this bending the supporting girders of the unbraced section are pivoted at their ends 54. When the tank is empty, adjustable legs 47 rest on the bottom and support the float whilst a manhole 26 and a venting valve are provided in the vicinity of the highest portion of the undersurface. Various configurations of both the upper and lower surfaces of the float are illustrated in the Specification.

Title: Stop motion for winding and twisting machine
IPC: D01H13/16
Filed: 1965-03-15
Abstract: 1,093,652. Stop-motion. LEESONA CORPORATION. March 15, 1965 [May 12, 1964], No. 10813/65. Heading D1D. In a machine for twisting and winding yarn comprising a supply spindle having a whorl engageable with drive means to rotate the spindle and twist the yarn, and drum-winding means having a package on a pivoted arm, there is a stop-motion actuated on failure of the yarn to pivot the arm to move the winding package off the drum and to move the whorl out of engagement with the drive-means into engagement with a brake to stop the twisting-spindles, and a yarn-catching member to prevent yarn 'being fed off the supply spindle when the stop motion is operated. When a yarn breaks, a feeler 42, Fig. 1, is rotated by a counterweight 52 to rotate a lever 46 fast with the feeler into the path of a member 56 which is constantly rocked by an arm 62. The lever is consequently raised and lifts the package arm 24 to raise the package off the driving-drum. At the same time, a spring-urged lever 32 pivoted to arm 24 at 34 is moved to engage a catch 32b with a detent 36a to hold the package-arm in raised position. So that the lever 46 is moved out of the path of the rocking-member 56, a finger 68 is provided which engages a member 66 fast with lever 46, when the lever is raised. The yarn is drawn from a package on a holder 70, with a protective cover 75, through a hole 76 in a rotor 78 driven by a whorl 88 to impact two twists to the yarn. The whorl and its associated spindle are carried by an arm 96 which pivots about a point 100 when a bell-crank 108 is rocked by a rod 118. This rod is connected to an arm 24 to be raised thereby when the package is lifted, while a lost-motion device 119 prevents the bell-crank being rocked as the arm 24 moves during the normal winding- operation. When the arm 96 pivots, the whorl is moved away from the driving-belt 90 into engagement with a fixed brake 124, Fig. 2; at the same time, the rotor 78 moves into contact with a pad 136 which traps yarn moving out of the hole 76. The brake 124 is carried on a resilient arm 121 which enables the brake to aline itself with the rotor. This arm and an arm 132 which supports the pad 136 are backed by stabilizers 128 and 130 respectively which ensure firm contact between the brake and whorl and the pad and rotor.

Abstract: 549,407. Drawing dies; die-holders; chucks. JEARUM, F. C., and GRODZINSKI, P. Aug. 26, 1941, No. 10854. [Classes 83 (iii) and 83 (iv)] Diamond and like dies are mounted in holders such that axial adjustment of the die in the holder controls the supporting pressure upon the die. Such holders may be used both during drilling the die and also during drawing or special holders may be used for each purpose. The diamond is first provided with parallel faces a on which the ends of the axis are indicated. It is then ground to truncated conical shape d, Fig. 3, and mounted in a corresponding socket e. A screw-cap f with a spigot engaging the die controls the axial position and consequently the circumferential pressure. Both parts are recessed for engagement with the spigot f<SP>2</SP> of a face plate on which the holder is mounted by screws h. Observation openings e<SP>3</SP> are provided and when the die is only rough ground, spots are polished that are located at the openings to secure the necessary transparency. When special holders are provided for use during drawing these are neither provided with the spigot recesses nor with holes for the screws. In cases when the diamond is not suited to the conical form a split conical adapter with a polygonal recess to suit the diamond is employed. The diamond in the holder may be drilled simultaneously from both sides by reciprocating the holder between axially fixed high-speed drilling needles. Alternatively the die is rotated but is fixed axially and non-rotating drilling needles are reciprocated with independent controls. The holders may be of stainless steel and be lined thinly with copper; aluminium or copper-aluminium alloy or like bedding material. Dies of double conical or pyramidal form may be employed the cap of the chuck thus having a corresponding recess.
