Abstract: 1375176 Television DEFENCE SECRETARY OF STATE FOR 17 Feb 1972 [22 Feb 1971] 5079/71 Heading H4F [Also in Division H1] A memory device which may be used to generate television signals comprises charge carrier injection and extraction means in a semi-conductor body 1, e.g. in the form of source and drain regions S1 and D1 respectively, and a plurality of capacitive gate electrodes C11-C16 spaced along an insulating layer over the channel between the regions S1 and D1. The insulating layer is capable of storing charges injected therein from the body 1 under the influence of a suitable voltage on any of the gate electrodes C11-C16, and preferably comprises a layer 3 of Si 3 N 4  on a layer 2 of SiO 2 , charges being stored at the layer interface 2a on tunnelling through the layer 2. Non-destructive read-out is achieved by measuring the current which can flow between the regions S1 and D1, this being influenced by the presence of any stored charges. The stored information may be erased by applying a gate potential of such magnitude and polarity as to cause the charge to retunnel back through the layer 2 into the body 1. The Si 3 N 4  layer 3 is preferably limited to a strip along the row of elements illustrated, similar strips being provided for other rows. Each strip 3 of Si 3 N 4  is bounded laterally, as well as beneath, by SiO 2 . A further SiO 2  layer may be provided over the gate electrodes 4, with additional capacitive electrodes (17), Fig. 8 (not shown), being situated thereon overlapping each adjacent pair of electrodes (4). The invention covers various alternative forms of input and output of information for storage. In one case, using optical writing and electrical reading, the body 1 is of Si, and charges are stored at the elements of a 2-dimensional array in response to incident radiation. The radiation may be white or monochromatic light and may represent a scene to be imaged.

Title: Improvements in the process of obtaining artificial threads of natural silk from colloidal solutions of natural silk
IPC: D01F4/00
Filed: 1928-02-18
Abstract: 312,114. Muto, T., Hida, S., and Kanegafuchi Boseki Kabushiki Kwaisha. Feb. 18, 1928. Natural silk, processes for making artificial silk from :-Artificial silk is made from colloidal solutions of natural silk, prepared for example as described in Specification 306,699, by coagulating the solution in a bath of acetic acid, methyl alcohol, or other known dehydrating agent and elongating the thread by sliding friction to four or five times its original length either during the coagulation or after the thread has been semi-coagulated and before the coagulation is completed. The thread is then wound up on a reel and dried. In the form of apparatus shown in Fig. 1, the semi-coagulated thread 1 is drawn through reducing holes 4 pierced in rubber membranes 2 suspended by holding frames 3, so that the thread is drawn out by sliding friction uniformly acting around its whole surface. In the form shown in Fig. 2, the semi-coagulated thread 1 is drawn between two pairs of cylindrical rolls 2, 2<1>, and 3, 3<1>, which rotate in the direction indicated by the arrows and are rigidly coated with a rubber costing 4, so that the thread is drawn out by sliding friction or lateral pressure uniformly acting on practically its whole circumference. Specifications 22753/07 and 21285/08 also are referred to.

Title: Improvements in or relating to safety catch means for rotatable handles
Inventor: FYSON RICHARD OLIVER
IPC: B66D1/06
Filed: 1968-02-01
Abstract: 1,214,031. One-way-acting detents. C. J. R. FYSON & SON Ltd. 7 Jan., 1969 [1 Feb., 1968], No. 5235/68. Heading F2E. [Also in Division B8] A rotatable handle and safety catch mechanism comprises a shaft 4 journalled for rotation in a supporting structure, a radial handle 10 on the shaft, a handgrip 12 rotatably mounted on a rod 11 fixed to the radial handle, a stop means 7 secured on the supporting structure, a detent 17 movably mounted on the radial handle 10 and positioned for releasable engagement with the stop means, and linkage 14, 13 coupling the detent to the handgrip so that force exerted on the handgrip tending to rotate it in one direction causes the detent to be urged into engagement with the stop means, and force exerted on the handgrip in the reverse direction causes the detent to be urged out of engagement with the stop means. As shown, the invention is applied to a handoperated rope winch for raising or lowering a conveyer run 1, Fig. 1, of a motorized belt conveyer C, relative to wheels 2. When the handgrip 12 is grasped to rotate the radial handle 10 in the clockwise direction, Fig. 4, to raise the conveyer, the handgrip 12 itself tends to be rotated in the counterclockwise direction, so the tie rod 14 linked to it forces downwards the pawl 17 (assisted by a spring 21) into engagement with the fixed ratchet 7. (The pawl 17 is pivoted at 16 to the radial handle 10). The " winding-up " action is not prevented by this engagement. When the handgrip 12 is grasped to rotate handle 10 to lower the conveyer, handgrip 12 tends to be rotated clockwise in the sense of Fig. 4, so pawl 17 is withdrawn from ratchet 7 against the force of spring 21 and the conveyer may be lowered freely. The spring 21 is an optional feature to ensure re-engagement of the pawl and ratchet whenever the handgrip is released.
