Title: Fabric heat treatment apparatus
IPC: D06B11/00
Filed: 1972-08-09
Abstract: 1441593 Heating and cooling printing cylinders STIBBE-MONK Ltd 16 July 1973 [9 Aug 1972] 37123/72 Heading B6C [Also in Division D1] Apparatus for heat treating a fabric 5, Fig. 5, comprises a rotatable roller 3, means for urging the fabric 5 against the roller 3, a heater 23 for evenly heating a section of the roller surface, a first sensor 8 for giving a response dependent upon the temperature of a first part of the section facing the fabric, a device for cooling a second part of the section adjacent or opposite an edge of the fabric, and a second sensor 17 or 18 for giving a response dependent upon the temperature of the second part, the arrangement being such that the cooling device and the heater can be operated so as to keep the temperature substantially constant across the width of the fabric. In a sublamatic printing machine 100, Figs. 1 and 2, a paper 106 printed with a dye pattern is unwound from a roll 104 to pass over a stationary heater 107 and a fabric 110 is unwound from a roll 108 to pass over a stationary heater 112. Printing is effected during passage around a rotatable steel calender roll 114 having internal electrical heaters 115 comprising a number of long electric filament heating rods extending across the roller 114 and shorter rods on each side of the roller. The fabric 110 and the paper 106 are urged into contact with the roller 114 by a pressure pad 116 comprising, in succession, an inner layer 25 of polytetrafluoroethylene-impregnated glass cloth, an optional felt layer, a resilient rubber layer 27, a layer of continuous steel plate and a layer 26 of circumferentially extending steel strips 122. All layers are secured to a bar 28 and all layers, except the layer 26, pass around a bar 29, the strips 122 being secured to the bar 29 by adjustable nuts 124. The bars 28, 29 are movable by rams 30, 31. A temperature control member 119 extends over an upper strip 118 of the roller 114 and is constructed and similarly to the temperature control member of Figs. 1 and 2. Take-up stations (not shown) for the fabric and paper are provided and there is a cooling device upstream of the fabric take-up station. In a modification, Fig. 3, the brackets 9, 10 are replaced by blocks 76 mounted one each side of the gauge 8 and which are slidable in a member 72 secured between plates 70. A sensor unit (not shown) is screwed into position below the member 72 between the plates 70. A further sensor unit 80 is secured to the blocks 76 which are provided with holes for allowing air to be directed downwardly through lower slots 74 in the member 72 on to the roller 3 or 114. Each sensor unit comprises a pick-up head 94 mounted in a casing 96, which head is spring urged into contact with the roller 3 or 114, and which transmits a signal corresponding to the sensed temperature to a control system. In modifications (not shown), instead of electrical heating, the roller is heated by hot oil circulation or hot gas or air circulation between an inner and outer wall of the roller or along tubes within the roller.

Abstract: 895,433. Road vehicle levelling valves. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 11, 1960 [Nov. 11, 1959], No. 38214/59. Class 108(2). A levelling valve for vehicle air springs comprises an open-ended hollow stem 32 giving access to a release or exhaust path 34, which is movable axially by an operating arm 24 to engage sealingly at its open end and unseat an admission valve member 42/46 biased to seat on a barrel 38 and in which the barrel and stem are relatively adjustable so that for a given position of the operating arm 24 the valve can be preset in the lapped position. In the embodiment a casing 10 houses the barrel 38, slidable stem member 26 and in a crossbore the cam body 20 which is rotated by the attached operating lever 24 and has a cam portion 22 which imparts axial movement to the stem member 26 against the bias of spring 36. In operation when stem member 26 moves left the hollow stem 32 seals against and then lifts primary admission valve 42 off seat 40 in the barrel when air from inlet 70 flows through the hole in secondary valve 46 until on further movement of the stem valve 42 lifts valve 46 off seat 48, allowing an increased air flow into casing 10. When the stem returns to the right, valves 46 and 42 seat on the barrel and then the casing 10 is connected through the stem with exhaust path 34. To preset the valve the arm 24 is fixed relative to the casing 10 as with a dowel 64 locating in holes in the arm and lug 59 provided on the casing and the barrel 38 is screwed in or out of the casing 10 until the valve is lapped. The barrel is then locked in position with locknut 68.

Abstract: 1,025,951. Thermal regenerators. SVENSKE ROTOR MASKINER A.B. Oct. 12, 1962 [Oct. 12, 1961], No. 38711/62. Heading F4K. In a thermal regenerator comprising a rotor supporting a bearing 42, a lifting arrangement is provided for freeing the rotor from its bearing for the purposes of servicing or replacement. As shown, the lifting arrangement comprises ledges 44 equi-spaced about the outer periphery of the rotor shell 10 and complementary ledges 46 similarly spaced about the inner periphery of a stationary rotor housing 28. When it becomes necessary to service the bearing 42, cover-plates 48 are removed from the housing and the rotor is slowly rotated (e.g. by an auxiliary drive 38) until opposed pairs of ledges 44 and 46 are so placed that the leading tapered edges 50 of the ledges 44 lie over the rear of the plane ledges 46 (see Fig. 3). Cylindrical rollers 54 of diameter greater than the least axial distance between the ledges are then wedged into the tapered spaces so formed. Rotation is then recommenced so that the rollers advance along the taper 50 until reaching surface 52. Simultaneously, the rotor shell is being raised free of its bearing 42. On re-assembly after the bearing has been serviced and replaced, the rotor is again rotated so that rollers 54 run up the trailing tapers of ledges 51 until the rotor again rests on its bearing. The rollers are then removed and the cover-plates 48 replaced.

The stem (191) is rotatable by a knob 193 and is threaded in sleeve (25) to axia ly move a closure member relative to a seat to regulate the flow between a cold water inlet 141 and a cold water outlet 142 to the heater via by-pass 26. Inlet 141 which has a filter (16) and outlet 142 are directly connected by a diaphragm operated valve linked to the gas control valve. The hot and cold water valves control flow respectively from the cold water inlet 141 and the hot water inlet 143 from the heater to a common outlet (147). The sleeve 23 is linked to a sleeve 29 having a swing-lever (293) rotatable about knob (193).

Abstract: 1275259 Spin dryers HOOVER Ltd 14 Aug 1969 [15 Aug 1968] 39028/68 Heading F4G [Also in Division D1] A spin-rinsing machine has a spin can 10 rotatable in a stationary container 11 by drive means 12, means for automatically interrupting the drive during rinsing so that the spin can runs intermittently, and means 40 for supplying rinsing water to the spin can at least while the can is being driven. The interruptions of the spin can drive during rinsing prevents the radial acceleration of clothes in the spin can from exceeding 300 g. and are effected by a pressure switch 30 which is sensitive to the water level in the container 11. The motor may be switched on for between 10 and 30 seconds and off for from one to two minutes. The motor may be operated continuously to provide a spin-drying speed. In use water is supplied through a spout 40 from a pipe 42 connected to a tap and, with a control knob 50 in a first position the spin can drive motor is started and stopped by the switch 30 when the water level reaches and falls to predetermined levels. Water is withdrawn from the container 11 by a pump 16 which preferably is driven, as through a belt 17, only when the spin can is rotated. In a second switch position the spin can is driven continuously for spin-drying. In both switch positions the lid 25 of the container 11 must be closed over the spout 40 to operate the motor 12. The washing machine shown includes a wash tub 35 with a heater 43 controlled by a stepped snapaction thermostat switch 53 (Fig. 2, not shown), a pipe 22 to the pump 16 and a horizontal-axis impeller driven by a pulley 39 from a motor 36, the motor starting when the adjustable thermostat switches off the heater. The spout 40 may be lifted and turned round to direct water into the wash container 35.
