Filed: 1975-10-19
Abstract: 1529217 Component assemblies AEI SEMICONDUCTORS Ltd 24 Sept 1976 [10 Oct 1975] 41624/75 Heading H1R The ground plane for a microwave circuit, comprising one or more components carried on one face of a substantially planar dielectric substrate, comprises an electrically conducting support bonded to the other face of the substrate by means of an insulating adhesive. As shown, an alumina substrate 1, which carries a microwave diode 3, is bonded at room temperature to the base of a gold-plated titanium box 2 by a cyanoacrylate glue. A conductor 8 is connected to the box 2 by a blob 10 of gold-loaded epoxy resin extending through an aperture 11 formed through the substrate 1. In this embodiment, the close matching between the thermal expansion characteristics of the materials of the substrate and base increases the thermal stability of the bond. For materials having dissimilar thermal expansion characteristics, temperature stability of the bond is achieved by bonding at a temperature above room temperature.

Abstract: 1329021 Controlling a lathe INDEX-WERKE KG HAHN & TESSKY 3 Sept 1970 [5 Sept 1969] 42229/70 Headings B3B and B3T In a method of setting a machine tool so that a working part of a tool carried by a tool carrier can be made to carry out working movements under the control of an operating programme, the tool carrier is moved from a fixed starting position to bring the working part of the tool to a predetermined control position and storing data representative of the distance moved by the tool carrier from its starting position to the control position whereby the operating programme can be arranged to control said working movements by reference to said data. In the embodiment described the machine tool which is an automatic turret lathe has a longitudinal slide 14 and a cross slide 18 which supports two turrets each carrying cutting tools. In order to control the machining operation of the lathe and to set the lathe so that each tool can carry out a predetermined programme controlled movement apparatus 10 is provided which permits the cutting portion of the tool to be accurately located at a reference point 84 defined by the intersection of two reference planes X and Y, X containing the axis of rotation of the spindle and Y being transverse to the axis of the spindle. The apparatus 10 comprises two L-shaped members 60 and 62 each member having two abutment faces 56 and 56<SP>1</SP> and 58 and 58<SP>1</SP> respectively the abutment faces of one member being perpendicular to the abutment faces of the other. Leg portions 64 and 66 of the members 60 and 62 respectively are normally held biased to an inoperative position in which none of the abutment surfaces lie in the respective reference planes. A cutting tool 26 is brought into the reference position 84 by displacement of the slides 14 and 18 the tool point 90 displacing the L-shaped members so that each abutment surface lies in its appropriate plane when the tool point is at the reference point 84. The displacement of the slides 14 and 18 from their initial position is measured by respective sensing devices 46, 48, and 42, 44 and the data so determined is co-ordinated with the displacement of the L-shaped members to determine successive movements of the cutting tool from its initial position. The displacement of the L-shaped members is sensed by switches 78, 80 and 82 which actuate pulse generators which indicate when the cutting tool is in the control position which in conjunction with the data received from the sensors 44, 48 establishes a motion sequence of the tool to the central position from which programmed controlled working movements of the cutting tool are effected. Any deviation due to tool wear can be corrected by the data received by the sensing devices 44, 48.

Title: Fabric laying machine
IPC: A41H43/00
Filed: 1971-09-17
Abstract: 1360506 Folding fabrics CUTTER MACHINE CO INC 17 Sept 1971 [21 Sept 1970] 43409/71 Heading D1S A cloth laying machine comprises a reciprocating carriage 30, Fig. 3, a pair of pivotably supported tuck blades 49, 50 for folding the cloth 25 at opposite ends of the carriage's traverse and means for latching the trailing blade (49 as shown) in a laying position and the proceeding blade in a raised position during each folding operation. Tuck blade 49 is connected to each carriage side wall 41 by a leg 52, pivot pin 55, arm 51 and pivot pin 53 and blade 50 is similarly connected by 62, 65, 61 and 53. Towards the end of a traverse catcher arms 36 are raised as their attached rollers ride up carriages cam arms 78. They swing leading blade 50 and leg 62 into a raised position in which the curved upper extremities 60, 70 of arms 51, 61 are received by recesses 73, 74 of legs 62, 61 so as to lock the blades 49, 50 into laying and raised positions respectively, as shown in Fig. 8. At this point catcher bar 35 on arm 36 and blade 49 have begun to make the fold. Roller 80 then falls between lands 76 and the carriage reverses direction (Figs. 9, 10, not shown) so that catcher bar 35 completes the fold and presses it down onto previous folds whilst blade 50 returns to its laying position and becomes the trailing blade. The cloth 25 is supplied from roll 22 over roll 26, dancer roll 27 and feed roll 28. If slack is sensed by dancer roll 27 it energises an electromagnetic brake 24 to retard the rotation of cloth roll 22 by means of ferromagnetic brake disk 125. Feed roller 28 is normally driven via left front carriage wheel 17, unidirectional transmission 89, Fig. 2, drive shaft 87, drive pulley 90, belt 91, variable speed pulley 92, first drive sproket 94, chain 95, first driven sproket 96, clutch 97 and shaft 86. The diameter of pulley 92 is adjusted by knob 99 and shaft 93 until cloth 25 is slightly underfeed by roll 28. If the cloth tension thereby produced becomes excessive the trailing tuck blade 49 is urged to rotate rearwardly about pivot 55, causing rod 119 to move away from finger 117 of microswitch 115 which therefore energises magnetic clutch 104. This causes shaft 87 to drive shaft 86 at a slightly faster rate via drive sproket 100, chain 101, driven sprocket 102 and clutch 104. In order to supply the additional cloth required for folding shaft 87 is arranged to drive shaft 86 at about 3 times its usual speed via clutch 106, sproket 108, chain 109 and sproket 110 near the end of each traverse. Clutch 106 is activated whilst plunger rod 127 is in contact with stop (128, Fig. 1, not shown). The height of the carriage is raised as each fold is made by the action of stop 132 upon plunger 130, Fig. 7. This makes link 133 vertical, thereby moving rack 136 and rotating gear 137. Pawl 140 prevents the reversal of gear 137 as rack 136 and link 133 resume their normal positions.

B15 with threshold values spaced out in arithmetic progression between Ad and Bd, those comparators of weights 1, 2, 4, 8 being used first to determine the segment in which an input analogue lies and then all the comparators to determine the position within the segment, the potentials at Ad, Bd being selected in accordance with the segment number and the potential at Bd being either zero or half that at Ad. In Fig. 1, the input analogue is applied at K and initially passes through unity gain amplifier G1 to the comparators B1 ... B15 and a comparator R which determines the sign of the input. The outputs of comparators R, B1, B2, B4 and B8 are coded, Fig. 3, to give the segment number bits A, B, C, a bit F for selecting G1 or G8 (having a gain of 8) and a bit Q1 for selecting whether Bd is at zero or half the potential at Ad in the subsequent determination of the position within the segment. The reference potential at Ad is selected in dependence on A, B, C and the sign of the input. The position-within-the-segment code bits W, X, Y, Z are formed, Fig. 3, from the outputs of all the comparators B1 ... B15. In a modification, Fig. 6 (not shown) the gain-of-8 amplifier is initially in circuit and is replaced by the unity gain amplifier if necessary. Instead of two separate amplifiers G1, G8 a single variable gain amplifier could be used in which case comparators B1 ... B15 need have only one measurement signal input each.
