Patent GB-1234656-A (GB)
IPC: H03F3/193
Filed: 1968-10-08
Abstract: 1,234,656. Transistor amplifier. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 8 Oct., 1968, No. 47661/68. Heading H3T. An IGFET having a first gate 6 receiving a signal to be amplified and a second gate 10 receiving a gain-controlling D.C. signal Vg 2  has a source resistor 18 whose value is sufficiently high (load line AB, Fig. 2, not shown) as to ensure that when the voltage (Vg 2s ) between the second gate 10 and the source 8 is changed ( + 4 v. through -1.5 v.) from maximum gain to second gate cut-off (A to B), the voltage between the first gate 6 and the source 8 (Vg 1s ) changes, in an opposite sense, by an amount (- 2 v. to + 3 v. ) which is at least as great as the difference between its value at maximum gain (- 2 v.) and its value at the first gate controlled cut-off point (C, - 5v.). The arrangement thus provides high amplfication (at A) for small input signals, but as the input signal magnitude increases the gain can be reduced and a linear operating range maintained, by moving the working point (along line AB) further from the non- linear part of the Vg 1s -I DS  characteristic in the region of cut-off (C) so that the increasing input signal has an increased length of linear characteristic to work on. Modulation distortion and cross-modulation are reduced. Enhancement or deplation mode is possible, using P or N channel transistors. The input 1 is coupled to the gate 6 through a capacitor 2, and the gate is connected to a bias level provided by resistors 20, 21 through a coil 3 tuned by a capacitor 4. The drain is also tuned 11, 12 and the output is taken therefrom through a capacitor 14. It is said to be known to have a small resistor for R18.

Abstract: 1,258,970. Steam treating fabrics. APLICACIONES DE SISTEMAS INDUSTRIALES S.A. 20 March, 1969, No. 14756/69. Heading D1L. The successive operations of a) winding a textile fabric on a perforated core with uniform tension b) insertion of the wound fabric into and removal from a steam-treatment autoclave, and c) unwinding of the fabric from the core are effected with the aid of a rotary distributor device which has three core carriers uniformly spaced around its axis and is adapted to move three cores successively and intermittently to each of the three stages, the three stages being carried out on the three cores simultaneously between each movement. As shown (illustrating one embodiment of the distributor device) fabric 8 and auxiliary interleaving fabric 86 is wound up on a core 15 while held in a distributor device 3 at station A with the aid of a blower 90. The device is then rotated to bring the wound fabric to station B where it is released, withdrawn along a guide 20, inserted in the autoclave by means of a rail 17 carried by the autoclave door 16 and returned to the device. The device is then further rotated to station C where unwinding is effected with the aid of a blower 89. Unwound fabric 8 passes on an endless belt 80 below drying and cooling means 5 while the auxiliary fabric is simultaneously fed back to station A for interleaving with further fabric to be treated. At station B, the core is released by movement of a pneumatically operated tongue 102. Alternative core-holding and releasing means are illustrated in Figs. 8-11.

A method of manufacturing an electron tube whose envelope contains a photosensitive layer comprises exhausting a space containing the tube envelope, a first support and a spare support for the photosensitive layer, both being independently movable, and a vaporizer, forming the photosensitive layer on the first support by deposition from the vaporizer whilst checking the characteristics of the layer and, in the event of a defect being found in the layer, replacing the first support by the spare one, forming a photosensitive layer thereon and subsequently sealing the completed tube in the same vacuum. The photosensitive layer may be formed on an envelope portion of the tube which is sealed by cold welding under pressure within the vacuum to the remainder of the tube envelope to form the completed tube. The first and spare supports may be symmetrically mounted with respect to the welding press, vaporizer and checking device, Figs. 1 and 2 (not shown), such that each is independently movable, e.g. by rotation about a supporting shaft, from a first position to a second position in correspondence with both the vaporizer and checking position and on to a third position to co-operate with the remainder of the tube supported on the movable portion of the press.
