Filed: 1956-12-13
Abstract: 822,200. Moulding glass. GENERAL ELECTRIC CO. Ltd. Dec. 6, 1957 [Dec. 13, 1956], No. 38109/56. Class 56. The manufacture of a moulded glass body includes the steps of mixing glass powder with a binder consisting of an acrylic resin which is capable, on heating to a temperature below the sintering temperature of the glass, of being depolymerised to the monomeric form without decomposition of the monomer, pressing the resulting mixture in a mould to form a compact of the desired shape, heating the compact at a temperature below the sintering temperature of the glass and for a time such that the acrylic resin is depolymerised and the monomer thus produced is substantially completely removed by volatilisation and further heating the compact at a higher temperature and for a time such that the particles of glass are sintered together to form a coherent dense vitreous body. Preferably the acrylic resin is a polymer of a lower alkyl ester of methacrylic acid such as butyl methacrylate. The resin is employed in the range of 5-15% by weight of the weight of glass powder. The glass compositions used are as specified in Specification 817,636. The binder may be introduced in the form of a solution in a volatile solvent which evaporates below the depolymerisation temperature, sulphur-free toluene being suitable for butyl methacrylate. Finely divided powdered resin may alternatively be used.

Abstract: 303,365. Soc. d'Etude et de Construction d'Appareils de TÚlÚmÚcanique. Dec. 31, 1927, [Convention date]. Steering, balancing, and regulating altitudes.- In power and relay controlling arrangements for aircraft, auxiliary control members mounted adjacent the usual manual control members are adapted to complete circuits for auxiliary motors which move the control surfaces while the manual control members follow up and open the circuits. The arrangements is shown diagrammatically in Fig. 1 in which a surface l is normally operated by a lever i connected by a member h to a lever arm b, p. For power operation, a lever a pivoted at b carries a brush c which is adapted to make contact with one or other of contacts e,. e<1> carried by a sector d rigid with the lever b, p. Movement of lever a thus completes a circuit for magnet g or g<1> which starts the motor so that the lever i is operated and, by its connection to the sector d, the circuit of the magnet is broken as soon as movement of lever a is discontinued. The ratio between the movements of the surface l and sector d may be varied by adjusting the lengths of the levers b, p and i. The invention is shown in Fig. 2 and applied to a control comprising a handwheel 2 which is rotated to operate the ailerons and is mounted on a lever 1 which is moved to operate the elevator. The wheel 2 rotates on a tube 4 carried by the lever 1, and an auxiliary wheel 3 is secured to a tube 10 which rotates and slides within the tube 4. The wheel 2 carries a stepped cylinder 14 of insulating material around the larger diameter of which are mounted contacts 30, 31, Fig. 4, separated by insulation. The auxiliary wheel carries a brush 20 which normally engages the insulating separator but which on rotation of the wheel engages one of the contacts to start the auxiliary motor. Adjustable springs 21 tend to keep the wheels 2, 3 in their normal relative angular positions. The smaller portion of the insulating cylinder 14 carries a pair of annular contacts 15, 16 separated by an insulating ring 17 and adapted to be engaged by a brush 26, when the auxiliary wheel moves axially in order to start the motor controlling the elevator. An adjustable spring 7 and springs 8, 9 tend to maintain the normal distance between the wheels 2, 3 and the axial movement is limited by a stop 19. In the control device, shown in Fig. 7, for the rudder, the usual rudder bar is shown at 32, the auxiliary bar 39 being mounted on the tube 40 which is rigid with the bar 32. Adjustable springs 34, 37 tend to holds the bars in the normal relative position and contacts 33, 36 and 41, 42 control the starting circuits of the auxiliary motor.

Abstract: 817,640. Voltage and current measurement; electric analogue calculating. GENERAL ELECTRIC CO. Dec. 28, 1956 [Dec. 30, 1955], No. 39486/56. Class 37. Apparatus for measuring the ratio of two electric analogue currents comprises a logarithmic amplifier, capacitances respectively charged by the input currents, and first switching means discharging the capacitances sequentially into the amplifier input; the corresponding logarithmic outputs thereof being connected sequentially by a second switch synchronous with the first to a meter indicating the difference between the outputs, and thus the ratio of the input currents. Input currents i 1 , i 2  (Fig. 1) charge capacitors 3, 4, alternately discharged by oscillating switch 9 through resistor 10 into the grid circuit of amplifying triode 13 directly coupled to phase splitting triode 19 having equal anode and cathode resistors 23, 24. Degenerative feedback is provided from the cathode of 19 to the grid of 13 over diode 35, while regenerative feedback from the anode of 19 through capacitance potentiometer 39, 40 to the grid of 13 compensates for the component of degeneration through the diode interelectrode capacitance. The anode and cathode outputs of triode 19 are connected by switch 31 operated synchronously with switch 9 through coupling capacitors to a metering device 33 indicating the difference between the two outputs of opposite polarities. In alternate positions of switch 9, capacitor 3 charges linearly to a voltage e 1  (Fig. 2) and discharges exponentially through resistor 10 with a current i 3  of peak amplitude proportional to i 1 , while capacitance 4 charges linearly to a voltage e 2  and similarly discharges exponentially through resistor 10 with a current i 3  of peak amplitude proportional to i 2 . The input voltages e 3  to the amplifier are thus exponentially varying on successive switching cycles and are reduced substantially to zero by the similarly exponential feedback currents in the diode 35, which by reason of its logarithmic voltage/ current characteristic develops a linearly varying back voltage e 4  on each switching cycle which represents the logarithm of the corresponding exponentially varying current i 3 . The alternate linearly decaying voltages e 4  have similar slopes for each switching cycle, but their magnitudes at corresponding points of each cycle represent the respective peak valves of i 3  and thus the respective valves of i 1  and i 2 . Since e 4  is logarithmically related to i 3 , the difference between successive values of e 4 , and thus the algebraic sum of the output voltages indicated by meter 33, are shown to be proportional to the ratio i 1 /i 2 . A single variable current is measurable by holding one input at a constant level while (Fig. 3, not shown) the storage capacitances may be eliminated and the inputs connected alternately to ground and to the logarithmic amplifier by a double synchronous switch.
