Title: Improved method of and means for controlling the supply of gas to the burners of water boilers
IPC: F24H9/20
Filed: 1944-04-15
Abstract: 582,015. Fluid-pressure servomotorcontrol systems. STOTT & CO. (ENGINEERS), Ltd., J., and JONES, A. April 15, 1944, No. 6966. [Class 135] A gas-operated diaphragm valve 12, Fig. 8, for controlling the supply of gas to the burners of a water heater 41 is adapted to be actuated by a thermostatic device 40, responsive to the temperature of the water and also by the operation of the water draw-off taps 33 or 34. The valve 12 as shown in Fig. 1 comprises a valve member 13 supported by a diaphragm 14 and co-operating with a seating 15. A chamber 17 behind the diaphragm is supplied with gas through a restricted passage 18 and has an outlet 19 to which a pipe 38, Fig. 8, is connected which leads to a thermostatically operated cock 40x and to cooks operated simultaneously with the draw-off taps 33, 34. Fig. 4 shows an arrangement of draw-off tap for drawing off water from a boiler 12b through a valve 22, a gas cock 21, in the pipe 38, being opened simultaneously by a tongue and slot connection 24, 25 to relieve the pressure in chamber 17 of the diaphragm valve to allow the valve to open fully. Fig. 6 shows another arrangement in which the gas relief valve is a lift member 28, which is actuated by a cam 29 on the water cock 22. Thus the thermostatically-operated cock 40x controls the pressure in chamber 17 to adjust the opening of gas valve 12 in accordance with the temperature of the water in the boiler whilst the opening of the draw-off cocks effects full opening of the gas valve independently. The gas passing from cock 40x and the gas cocks associated with the draw-off taps is led by pipe 39 to be burnt adjacent the main burners. The valve member 13 of the gas valve 12 is prevented from closing completely by an adjustable stop screw 16 to allow sufficient gas to pass to keep the burners alight.

Patent GB-208063-A (GB)
Title: Process of making articles from pulp
IPC: D21J7/00
Filed: 1923-03-12
Abstract: 208,063. Drake, W. H. March 12, 1923. Moulding pulp.-Relates to the process of moulding articles from pulp wherein pulp carrying liquid is introduced into the mould to deposit the fibres on the walls of the mould, the flow of liquid being checked after the mould is filled to a predetermined degree and the pressure in the mould increased by introducing an anhydrous fluid under pressure; and consists in causing the pressure fluid, by the use of a tapered inlet to the mould, to act as a jet or current and flow through the pulp carrying liquid entirely across the mould. Apparatus for carrying out the process is described but not claimed. As shown in Fig. 6, pulp carrying liquid flows from a tank 22 through a valve 25 into a reservoir 24 terminating in a restriction 41 leading to the mould 10. After the pulp has been deposited to such an extent as to retard the flow, the valve 25 is closed and a valve 29 is opened, admitting air or superheated steam under sufficient pressure to cause a current across the mould. Fig. 1 shows the apparatus. The mould 10 comprises side sections carried by levers 11 movable through slits 14 by pins 13 on a wing 12 operated through levers 16, 15 by cam mechanism 17; and a movable bottom 18 controlled .from the member 17 through a link 20 and lever 19. The valves 25, 29 are controlled from the member 17 through levers and links 27. 31 respectively. The pressure within the mould is released, immediately before opening, by a venting piston 34 operated from the member 17 through a lever 40.

Title: Machine for making boxes with lids
IPC: B31B105/00
Filed: 1932-03-09
Abstract: 381,467. Making hinged-lid boxes. UNIVERSELLE CIGARETTENMASCHINENFABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. March 9, 1932, No. 7079. Convention date, March 25, 1931. [Class 18.] In making boxes with hinged lids by assembling a body and lid and providing them with an edge binding strip which is cut at three sides so that the lid can be opened about the fourth side as a hinge, the lid or body blank feeding means and the corresponding forming devices, comprising upper and lower heated shaping members, are driven directly from the driving motor 52, Fig. 3, so that when other parts of the machine are thrown out of operation, the blank feeding means and heated shaping members continue to operate ; both the lid and body blank feeding means and heated shaping members may be arranged to be driven directly from the driving motor. As shown, the lid-forming device and lid-blank feeding means are driven from a shaft 50 driven directly from the motor 52, the shaft 51 driving the body-forming devices &c. being driven through a clutch 57 ; the knives 33, Fig. 1, for cutting the edge binding strip are also driven directly from the motor 52. The shaft 50 includes a pin clutch 70 which, should a stoppage occur in the lid-forming device, is actuated automatically or by hand to arrest the plungers thereof always at their lowest positions. The lid-forming device operates on two blanks at a time which are fed by pushers 1, Fig. 2, actuated by cams from the shaft 50, over heated plungers 6, which are actuated by cams from the shaft 50 to lift the blanks and press them into the heated stationary members 11 while ejectors 13 mounted in the members 11 are forced back against the action of springs 15. On the return of the plungers 6, the formed lids are pressed thereon by the ejectors and deposited by the descending plungers on to angle-bars 16 at the sides of the plungers, the lids being then thrust by a pusher 17 into slideways 18, 19 arranged above a conveyer 20 driven from the shaft 50. The conveyer 20 carries the formed lids against a stop 23 where a pusher 25 also actuated from the shaft 50 moves the lids on to a convever 28 driven in the opposite direction to the conveyer 20 from the shaft 51 and carrying the lids to the assembling device 29. An extension 24 on the pusher 25 prevents lids on the conveyer 20 from becoming injured by the pusher on its return stroke and should the clutch 57 be disengaged the lid-forming devices, conveyer 20, &c. continue to operate and the formed lids are moved by the pusher 25 across the conveyer 28 into a receptacle 42. The assembling device 29 and the means for attaching the edge binding strips, cutting the edge binding strips, opening the lids and removing the shaping blocks from the opened boxes are described in Specification 351,631.

Title: Improvements in and relating to a.c. induction electricity meters
IPC: G01R11/36
Filed: 1930-03-04
Abstract: 356,718. Supply meters. KUPECZEK, A. and MEASUREMENT, Ltd., Townsend House, Greycoat Place, London. March 4, 1930, No. 7116. [Class 37.] Induction motor meters have separate shunt and series magnets, the series fl u x a t full rated load being given a value of about a quarter of the shunt flux value by means of a magnetic bridge between the poles of the series magnet. The shunt magnet consists of a U- shaped laminated core having coils 3, 4, Fig. 4, on its legs 1, 2. Below the coils is arranged a magnetic shunt 5 with an airgap at each end. The shunt 5 is reduced in section at one part so as to become saturated at high voltages and thereby give increased torque. Copper loops 6, 7 are arranged on the limbs 1, 2 to give slight over-compensation of the phase angle. The series magnet, shown in Fig. 5, is of G-shape and is formed of a set of laminations 10 carrying the series coil 12 and another set 9 forming the counterpole. A third set of laminations 11 forms the lower polepiece and is extended to serve as a magnetic shunt. The polepiece 11 is riveted to a U-shaped nonmagnetic fixing piece 13 which is fastened to the core 10 by a screw 14, Fig. 4. A spacing plate 15 may be inserted between the fixing piece 13 and the main core 10 to adjust the airgap to the desired value. A nonmagnetic spacing-plate 16 is inserted between the magnetic shunt and the core 9, its thickness being determined in accordance with the low-load minimum of the curve of errors. The section of the magnetic shunt is reduced at its outer end in order to limit the flux passing through. This. section may be altered by an iron adjusting- screw or a lever. The shunt and series magnets are carried by an iron frame 8 having flat counterpoles 17, 18 for the shunt magnet. Final adjustment of the fluxes to quadrature is effected by a coil 20 on the series core in series with an adjustable resistance. Compensation for friction may be effected by an iron lever carried by the frame 8 and adjustable with respect to one of the shunt poles, or the airgap between one of the poles 1 and its counterpole 17 may be varied. The shunt fluxes traversing the rotor may be in parallel instead of in series.
