Abstract: 1,224,827. Winding webs. MASCHINENFABRIK STAHLKONTOR WESER LENZE K.G. 3 April, 1969 [8 April, 1968], No. 17467/69. Heading B8R. In a web-winding machine the web 14 passes over guide rollers 16, 17, 18, a pressure roller 19 and an empty core H 2  to a core H 1  where it is wound into a roll R 1 , the cores H 1 , H 2  being mounted on winding cones carried by rotary discs (Fig. 2, not shown); during this winding operation a swinging frame 25 carrying further pressure rollers 27, 28 and a knife arrangement 31 is in the position shown in chain-dotted lines, but the frame is moved into the position shown in full lines just before the reel R 1  is fully wound. In this latter position the empty core H 2 , with the web 14 wrapped around more than half its circumference, is centred and supported by the three rollers 19, 28, 27; the knife 31 is then operated to sever the web 14 on the core H 2 , and air guided by a plate 36 is blown through the roller 28 on to the core so that the leading edge remains in contact with the core. After a few layers have been wound on the new core the frame 25 is swung away, the winding cones embracing the core H 1  are retracted, the full reel R 1  is swung into a delivery position by means of rocker arms 31, and a new core is fed to the winding cones from a magazine 49. With the new core H 2  now being wound the frame 15 carrying the pressure roller 19 moves back along a guide rod 22 until shortly before the required diameter of the winding or set length of web being wound is reached; a motor is then actuated to pivot the rotary discs so that the empty core is swung towards the pressure roller 19 and the almost fully-wound reel is swung into the second position (as the reel R 1 ) when the changing and winding cycle, which may be controlled by an electric counting device, is recommenced. The pressure roller 19 is perforated (Fig. 3, not shown) in order to permit the escape of air entrained between the roller and the web, whilst the cut-off knife is mounted for limited rotation on its carriage (Figs. 4 and 5, not shown) to allow for automatic alignment during the cutting operation.

Title: System for maintaining a substantially constant temperature in a plurality of boilers feed pipe of a central heating system comprising
IPC: F22B31/04
Filed: 1958-06-03
Abstract: 854,151. Automatic temperature control systems. REGULATOR A.G. June 3, 1958 [June 26, 1957], No. 17628/58. Class 38 (4). In a central heating system, the temperature of the hot-water supply from a plurality of boilers is maintained constant with variation in heat load by regulating a first boiler and with increase of load connecting into the system additional boilers, each operating at maximum delivery. In an embodiment, an automatic regulation control 15 responsive to signals from a regulating thermostat 8, in a hot-water return pipe 6, controls the light-up or shut-down of boilers 1-3 through programme switching apparatus 61-63. A thermostat 7 in a hotwater feed pipe 5 controls a fuel pump and air control arrangement 71 of boiler 1 so as to maintain constant the temperature in the feed-pipe. The thermostat 7 also affects the operation of the programme switching apparatus 61. At start-up, the programme switching apparatus associated with the particular boiler in response to a signal from the regulation control 15 starts up a flue fan 21-23 and opens a valve 81-83 supplying gas to a burner 11-13 if the gas pressure is sufficient to actuate a pressureswitch 91-93. The gas is ignited electrically and fuel oil is supplied to the burner through a valve 51-53. During operation, the programme switching apparatus controls the fuel valve 51-53 and flue damper 31-33 in response to signals from thermostats 111-113, 121-123  and flame photo-cell 101-103. The operation of the flue damper is partially dependent on signals from a pressure switch 41-43 sensing furnace gas pressure. At shut-down, fuel valve 51-53 is closed and for boilers 2, 3 hot-water return valves 132, 133 are closed. Hot-water circulation is maintained by a pump 66. A minimum thermostat 9 rings an alarm in the regulation control 15 when the return-pipe temperature falls below a predetermined value.

Filed: 1924-07-25
Abstract: 219,975. Ruppert, W. July 31, 1923, [Convention date]. Void [Published under Sect.91 of the Act]. Clutches.-In automatic release devices for power transmissions embodying heavy masses, such as for presses, the retardation due to overload or shoch causes an auxiliary oscillatory mass, normally moving synchronously with the transmission elements, to disconnect them by virtue of its inertia. As applied to a clutch, Fig. 3, a disc 18, secured to a shaft 16, is connected to a driving-wheel 17, loose on the shaft or secured to a driving-shaft, by a pivoted pawl 19, which engages under the pressure of a spring 21 a recess 22 in the wheel 17 and a cam 26 on an auxiliary flywheel 23. This flywheel has a limited freedom on the boss of the disc 18 determined by a stop 24, and when its inertia causes it to overrun the disc, the pawl 19 is cammed out of the recess 22. In a modification, Fig. 7, the shape of the cam 35 and position of the stop shoulder 39 are such that the spring pawl 36 is never fully disengaged from the cam, but acts, when the recess 38 is suitably positioned, to return the flywheel 31 as soon as the shock or overload has passed. In a further modification, the auxiliary flywheel acts by a pin to turn a cam lever against a spring which normally causes it to hold clutch shoes expanded against a driving-drum. The driving or driven flywheel or pulley 55 shown in Fig. 10 is clutched between fast and loose discs 56, 57. Plate springs 60, 61 act through adjustable abutments to turn the auxiliary flywheel 58 mounted on screwthreads on the shaft 59, thereby applying clutching-pressure which is relieved when the flywheel 58 overruns. Re-engagement of the clutches may be cushioned by mechanical, pneumatic, or hydraulic means.

[Class 37.] An electrolytic condenser with spaced electrodes, one of which is electrolytically " formed," has an interposed conductive composition which comprises a glycol, e.g. ethylene glycol or a glycerol, containing a suspension of a film maintaining electrolyte, e.g. ammonium borate and boric acid, which after being heated forms a pasty mass containing crystals on cooling. The electrodes are plates 1, 2 of aluminium or magnesium, the anode being chemically cleaned and electrolytically formed in a solution containing 92 per pent of water, 5 per cent ammonium borate and 3 per cent boric acid by weight at 60‹ C. for one hour at 450 volts, the part of the electrode extending above the forming solution being coated with lacquer prior to forming. The electrolyte is made by dissolving a powdered mixture of ammonium borate and boric acid in a glycol such as ethylene glycol at its boiling point, the mixture crystallizing on cooling. The composition is then heated to 60‹ C. to render it plastic prior to coating it at 3 onto a paraffin impregnated separator 4 which is finally placed between the electrode plates 1, 2. The condenser is then rolled and wrapped in varnished paper and placed in a metal container, the whole being dipped in asphaltum and dried and the condenser finally aged. In place of boric acid, citric, malic, lactic, tartaric or phosphoric acids may be used. The electrolyte comprises 42 per cent ammonium borate, 27 per cent boric acid and 31 per cent ethylene glycol by weight.
