Title: A method and apparatus for summating the integrations of any number of integrating quantity meters
IPC: H04N1/31
Filed: 1929-07-01
Abstract: 335,897. Reyrolle & Co., Ltd., A., and Bowden, G. H. July 1, 1929. Counting - apparatus with variable-step movement, - To sum the readings of a number of integrating meters, a total indicating reader is associated with each meter in succession through a selector device and during-each such association advances through an amount corresponding to the change in the reading of the selector meter since the last association of the indicating reader and that meter. For this purpose the selector simultaneously starts through electromagnetic clutches the indicating reader and a contact arm which moves at the same rate as the total indicating reader and pursues the pointer of the selected meter; when the contact arm overtakes the pointer the clutches are put out of action and the contact arm and the total indicating reader stopped. The Figure shows the connections of a device employing a selector D carrying triads of contacts E<1>, F<1>, G<1> - - E<5>, F<5>, G<5> corresponding to the different integrating meters B. The contacts E<1> and G<1> complete a circuit between the supply bus-bars C and C<1> through coils A<6> and B<5> which operate electromagnetic clutches connecting the total indicating mechanism to a constant speed motor A<3> and the contact arm B<1> of the first integrating meter to a constant speed motor B<3>. In the meantime the contact F<1> has connected the coil of a cut-out H to the pointer B<2> of the first integrating meter, so that when contact arm B<1> overtakes this pointer the cut-out H is operated and the circuits of the coils A<6>, B<5> broken. A second contact H<2> of the cut-out keeps the circuit of the cut-out closed until the selector has moved away from the contacts E<1>, F', G<1>. If the readings of some of the integrating meters have to be subtracted from those of the others, these meters, instead of being connected to the coil A<6> are connected to a coil A' operating a second clutch through which the total-indicating reader is driven backwards. The clutches of integrating meters at a distant station may be operated from their own supply bus-bars K<5>, K<6> through relays K<1> connected to the contacts F<4>, F<5> through line wires K. An arrangement of distant stations wherein each distant station has its own selector moving in synchronism with the' selector D is also described.

Title: Apparatus for winding a strand forming package
IPC: B65H54/28
Filed: 1961-06-06
Abstract: <PICT:0947414/C1/1> <PICT:0947414/C1/2> <PICT:0947414/C1/3> Glass strand 30, formed by collecting filamentary streams 26 emerging from a bushing 18 and sized by engagement with an applicator roller 34, is wound in a series of superposed parallel layers on a forming tube 28 carried on a collet 29. As each layer is completed and the next successive layer is commenced, either the bushing temperature is increased, thereby gradually decreasing the viscosity of the glass to permit more glass to be attenuated as the winding progresses, or the speed of rotation of the tube is decreased to compensate for the increased diameter of the package (see Division D1): the diameter of the attenuated filaments is thus maintained uniform.  Apparatus whereby the temperature of bushing is increased stepwise, Figs. 8 and 9, is actuated by limit switches 203, 204, Figs. 3-6 (not shown), and 9, on the winder 45.  As shown, a measuring and regulating unit 215 receives a signal corresponding to the temperature of bushing 18 from a thermocouple 216. An auxiliary signal from a variable resistance unit 218 causes a decrease in the total signal (falsely indicating that the temperature is falling from a pre-set value) so that unit 215 sends a signal to a saturable core reactor 206, the reactance of which is thereby reduced to permit more current to be supplied to transformer 208 and therefore more current to bushing 18.  In the operation of the unit 218, closure of limit switches 203, 204 energizes solenoids 234, 240 to operate pawls 232, 236, which turn ratchet 230 and change the position of a potentiometer-connected rheostat 224 stepwise corresponding to each axial movement of collet 29.  The variable voltage derived from rheostat 224 is used to pass current through resistance 233 in series with thermocouple 216 and unit 215. A conventional stepping switch and a series of fixed resistances may replace the ratchet, pawls and rheostat. Specifications 595,094, 909,154 and U.S.A. Specifications 2,607,197 and 2,873,718 are referred to.

IPC: F02C9/42
Filed: 1965-05-18
Abstract: 1,143,911. Fluid-pressure servomotor systems. JOSEPH LUCAS (INDUSTRIES) Ltd. June 23, 1966 May 18, 1965], No. 20925/65. Heading G3P. [Also in Division F1] The invention relates to a control means for an installation comprising a plurality of gas turbine engines 10, the control means being arranged to match the outputs of the engines. The engines are provided with individual power control units 12 which are responsive to changes in the respective compressor discharge pressures. Each of the engines has associated therewith a valve means 13 which comprises a first diaphragm 15 and a second diaphragm 26, the diaphragms providing three chambers, the inner chamber being connected to the compressor discharge pressure and the two end chambers being connected through lines 25, 23 and restriction 24 to a fluid-pressure derived from a pump (not shown) driven by the engine. The diaphragm 15 controls a valve 17 which co-operates with an orifice 18, the valve controlling flow of air under pressure through line 19 from the compressor discharge to the fuel control unit 12, the line 19 being connected to atmosphere through a fixed restriction 20, the line 19 with the variable restriction 17, 18 and the fixed restriction 20 constituting a fluid potentiometer. The second diaphragm 26 carries a valve member 27 which co-operates with an outlet 28 leading to line 29 and so to line 30 leading back to a reservoir. The line 23 of each engine is connected to the lines 23 of the other engines and the line 29 of each engine is connected to the lines 29 of the other engines. The fluid chamber defined by the diaphragm 26 of each engine is connected by line 34 to a single unit 31 by which the assembly of engines is controlled. The unit 31 comprises a chamber defined by a diaphragm 33, the diaphragm carrying a valve member 35 which co-operates with an opening 36 which leads by way of lines 37, 29 and so back to the reservoir, the chamber itself being connected by lines 34 to the chambers defined by the diaphragms 26 to which the fluid-pressure is applied through lines 23. The position of the diaphragm 33 and valve 35 is controlled by a cam acting on a piston 39 a spring 38 being interposed between the piston 39 and the valve 35. In operation for example during acceleration conditions, one engine may have a slower rate of acceleration than the others and its compressor discharge pressure will therefore be less than the fluid-pressure existing in the system, the valve disc 27 will therefore open and fluid will flow from the system 25, 23, and chamber to the right of diaphragm 26 through the lines 29 and 30 to the reservoir, that is the fluid-pressure of the system will fall. The differential pressure acting on the diaphragm 15 will move the valve 17 to the right to open the orifice 18 so that increased flow of air to the control unit 12 will occur resulting in increased flow of fuel to the engine and thus increased speed.
