Title: Improvements in or relating to method and apparatus for machining a cylindrical bore and to a gauging device for use in such machining operation
IPC: B24B33/06
Filed: 1940-10-03
Abstract: 543,715. Grinding machines. MICROMATIC HONE CORPORATION. Oct. 3, 1940, No. 14848. Convention date, Oct. 3, 1939. [Class 60] In a machine in which a reciprocating honing tool 11 which also rotates within a cylinder 10 to form a bore of required diameter by means of a series of radially movable abrading-stones 12 gauging of the aperture is effected by measuring the diameter of the honing tool without interrupting the operation of the machine, and the gauging-device may stop the machine when the required diameter is obtained. The tool moves through the cylinder at each end, and at one end the gauging device is pivoted to a guide sleeve 14 co-axial with the cylinder 10, and consists of a pair of pivoted caliper arms 19, 21 fitted with shoes 54 of a hard substance such as tungsten carbide which are adjusted so that they will contact with the abrading stones 12 when the required internal diameter is nearly completed. The arms 19, 21, are joined by a strip of twisted wire 32 connected to a spool 34 which is angularly adjustable in a split bearing at the end of the arm 21 and can be set to the required angle by the aid of a pointer 35 and scale 36. The wire is also connected to an adjustable screw 28 which is clamped in a split bearing when adjusted to set the arms 19, 21 the required distance apart. The wire 32 passes through a slot 48, Fig. 5, in a cam shaft 46 which is rotated as the arms 19, 21 are moved apart until finally a switch 53 is operated to close a circuit which operates a relay to de-energize the driving- motor and stop the machine. The shaft 46 can operate a registering device to indicate the internal diameter of the cylinder. The tool 11 is supplied with a coolant liquid from an orifice 15 in the supporting casting 16 and apertures 17 in the sleeve 14, and the tool is fitted with wiper guides 13 which engage the surface of the sleeve 14 and position the tool body within' the cylinder when the stones 12 are collapsed.

A coupling for two tubes 4, 4<SP>1</SP> comprises a casing 8 having a main bore 10 and disposed between the adjacent ends of the two tubes, two coaxial units 16, 16<SP>1</SP> slidably mounted in the main bore and each having a gasket 28, 28<SP>1</SP> for engagement with one of said tube ends, a deformable sealing member 30 connecting the two units, and means for urging the two units apart to engage the gaskets against the tube ends. The casing is slidably mounted for axial movement on a fixed stud 12, the casing bore 14 receiving the stud being flared at either end to permit slight swivelling movement. Each of the coaxial units consists of a nipple 26, 26<SP>1</SP> carrying a gasket and a flange member 20 slidable in the casing bore, said nipple and flanged member being connected by a multipart collar 24 which also serves to clamp the associated end of the bellows-type sealing member of polytetrafluoroethylene to the unit. The means for urging the two co-axial units apart comprises pairs of opposed pistons 34, 34<SP>1</SP> working in four subsidiary casing bores 32 supplied through a pneumatic or hydraulic circuit consisting of a shut-off and connecting nipple (38) and casing passages (36), Fig. 2 (not shown).

Title: Improvements in or relating to a folding and collecting cylinder for folding machines
IPC: B65H45/16
Filed: 1964-04-10
Abstract: 1,060,865. Folding and collecting cylinders. MASCHINENFABRIK WINKLER, FALLERT & CO. A.G. April 10, 1964 [May 24, 1963], No. 14873/64. Heading B6H. The collecting cylinder 2 of a folding machine is made up of individually adjustable segments 9, 10 and 11 whereby the radial distance between the centre of the cylinder and each segment is adjusted by cam means as the cylinder rotates, so that the peripheral speed of a segment or the outer sheet on the segment is the same as the speed of the sheet being collected. Each segment is pivoted at 12, 13 to links 14, 15. The links are mounted on spindles (16), Fig. 3 (not shown), and connected by a cranked lever 17. Each link 14 carries a slotted member (18), Fig. 2 (not shown), in which a cam follower is adjustably positioned. The cam followers co-operate with a cam which rotates three times in two revolutions of the cylinder whereby the segments move towards and away from the centre of the cylinder. Hence, as sheets are collected on a segment, the segment moves towards the centre of the cylinder so that the outer sheet is kept at a constant distance from said centre. The knife blades 5 of a cutting cylinder 1 are offset such that the arc a is less than the arc b. The blades 5 cut against rubber blocks 7. The folding blades 22 push the completed sets of sheets into the jaws of the folding cylinder 3.

Title: Dielectric amplifier using non-linear capacitors
IPC: H03F11/00
Filed: 1965-04-08
Abstract: 1,093,643. Dielectric amplifiers. CESKOSLOVENSK‡ AKADEMIE V•D. April 8, 1965 [April 8, 1964], No. 14921/65. Heading H3B. A differential amplifier using non-linear capacitors consists of two parallel-connected branches, each containing a coupling capacitor, C v1  and C v2 , Fig. 1, a non-linear capacitor C N1 , C N2 , and a load impedance Z 1 , Z 2 , there being an alternating current source G connected across the branches, and the two inputs being connected respectively through low-pass filters F 1 , F 2 , to the junctions a, b, between a coupling capacitor and a non-linear capacitor; the output is taken from the junctions e, f, each between a non-linear capacitor and a load impedance, and a rectifier U is connected between these junctions. The A.C. from the source G appears at the points e, f as a pulsed voltage, the size and shape of which (Fig. 2b, 2d, not shown), depends upon the D.C. bias applied to the non-linear capacitors by the input signals at a, b. The output of the amplifier is the result of subtracting the two signals at e, f (Fig. 2e, not shown), and the unidirectional voltage produced by the rectifier U is then proportional to the difference between the two input signals. The rectifier U may be a diode, Fig. 1, a rectifying circuit (Fig. 3, not shown), or a transformer and a bridge rectifier (Fig. 4, not shown). Alternatively, the load impedances may be constituted by the two halves of a centre-tapped transformer primary (Fig. 5, not shown), of which the secondary drives a rectifier circuit. The sensitivity and stability of the amplifier is improved by including one positive voltage feedback circuit (Fig. 6, not shown), connected to the input filter F 2 . The input capacity of an input (e.g. input 1) is increased by a positive feedback circuit (Fig. 7, not shown), connected to the junction g of two capacitors C<SP>1</SP>V 1  and C<SP>11</SP>V 1  which together constitute one coupling capacity C V1 . The linearity of the amplifier may be increased by a negative current feedback circuit wherein the input terminal H (Fig. 7, not shown), is connected to a point h in the transformer secondary circuit instead of to the point d in the primary circuit.

[Also in Division F1] A fuel supply system for a gas turbine engine comprises a variable output pump, a throttle valve, and an engine driven hydraulic signal generator capable of producing a signal which is a function of engine speed, and a further valve to which this signal is applied the servocontrol unit of the pump being so connected as to vary the pump output in response to the pressure drop across the throttle valve and the further valve. The system shown in Fig. 1 comprises a swash-plate type pump 10, the swash-plate 11 of which is controlled by a servo device 12, the fuel delivered by the pump passing through a throttle valve 13 which may be a metering valve, a further valve 14 and thence through line 19 to the combustion equipment. The hydraulic signal generator 15 which is driven by the engine produces a pressure signal proportional to engine speed and this pressure is applied through line 17 to the further valve 14 which thus controls the orifice 18. The pressure drop across the throttle valve 13 is proportional to the square of the engine speed. In a second embodiment Fig.2, a hydraulic potentiometer comprising a fixed restriction 20 and a variable restriction 21 is connected across the hydraulic pressure signal generator 15 and the mean pressure of the potentiometer is applied to the piston of the further valve 14. The variable restriction 21 is controlled in dependence on fuel temperature and may possibly be adjusted for different fuel densities. A bleed passage 22 is provided from the line 17 to allow escape of air from the centrifugal pressure generator.
