Title: Semiconductor arrangements for use as fixed value stores
IPC: H01L23/525
Filed: 1971-05-11
Abstract: 1312171 Semi-conductor devices SIEMENS AG 11 May 1971 [12 May 1971] 14347/71 Heading H1K Back-to-back pairs of Schottky diodes are employed as storage elements in a programmable fixed value semi-conductor store. The storage element shown comprises an island of n type material defined in an n type Si epitaxial layer 3 by a p type substrate 1 and diffused p<SP>+</SP> type isolating walls 4 and carrying two Al conductors 15, 16 which form Schottky contacts with the island through apertures 8, 10 in an oxide layer 7. An isolated ohmic Al contact 17 is provided between the two Schottky contacts, on an n<SP>+</SP> type zone 5 within the island extending down to an underlying n<SP>+</SP> type buried layer 2. The conductors 15 extend across the oxide layer 7 interconnecting like Schottky contacts within each row of the array of storage elements. The conductor 16 is connected, through an aperture in a second dielectric layer 25, with a further conductor 27 interconnecting like Schottky contacts within each column of the array. In a modification each conductor 27 is replaced by a p<SP>+</SP> type channel within the n type layer 3 and separated from the storage elements, to which it is connected by a metal conductor, by a p<SP>+</SP> type isolating wall. Programming of the storage elements in order to introduce to the store the desired value to be permanently stored is effected by applying a large voltage between the desired pairs of conductors 15 and 16 so as to cause part of the conductor 15 to melt and alloy with the semi-conductor material at each of the selected storage elements, producing a breakdown channel 30 to the ohmic contact 17 which short-circuits one of the Schottky diodes and thereby permanently alters the conduction of the element concerned.

Title: Improvements in or relating to baling presses
IPC: B30B9/32
Filed: 1924-06-14
Abstract: 239,613. O'Donnell, R. June 14, 1924. Baling-presses.-Relates to means for permitting the clearing of a baling-press for scrap metal when the head and the casing have become wedged by the material being baled. The head 3, Fig. 1, is carried by the plunger 2, and reciprocates in a rectangular box 4, the cover 5 of which is adapted to be drawn into the position shown in broken lines. The head of the plunger is notched ur corrugated at 9 to correspond with corrugations 10 on the box and is formed with guide arms 13 corrugated at 14. In use, the box is filled, the cover closed and the plunger 2 is moved to the left until the head is in the position shown in Fig. 1. A second ram 12 then compresses the material vertically. If wedging has taken place, the ram 12 is retracted and the plunger 3 is advanced to the position shown in Fig. 2, so that it may be cleaned, the arm 12 supporting it in the correct position for retraction, and the head may be slightly tapered inwardly to facilitate this action. In order to prevent the plunger from normally arriving at the extended position, means such as a removable yoke 20 is placed so as to engage the headed ends of stay rods 15 on the plunger. In order that the plunger may be withdrawn at the rearward position, the sides of the box, where they contact with the guides 13, are extended at 24. To provide for wedging between the guide arms 13 and the corrugations on the extensions of the box, the latter are arranged as at 26 - - 28, Fig. 6. In a modified form of press, the plunger may be fixed and the casing adapted to be reciprocated with the ram head at its end, or the casing may be moved to clear the plunger by auxiliary plungers.
Patent GB-496268-A (GB)
Title: Improvements in or relating to apparatus for simultaneously spinning and twisting artificial threads
IPC: D01D5/18
Filed: 1937-05-24
Abstract: In a modification of the apparatus described and claimed in the parent Specification, a non-rotating filling vessel 12 is arranged above a rotary precipitation vessel into which the threads are discharged by a rotating nozzle, the filling vessel is displaceable in the direction of movement of the thread together with a part 1 of the precipitation vessel, and means are provided for automatically interrupting the feed of the precipitation liquid upon displacement of the said movable parts.  The filling vessel 12 is connected by a flexible <PICT:0496268/IV/1> <PICT:0496268/IV/2> <PICT:0496268/IV/3> pipe 41 to a feed vessel 42 for precipitation liquid.  The rotary vessel is in two parts 1, 30 connected by a bayonet joint 31, 32. The lower part carries the spinning nozzle 33.  The vessel is rotated by a motor 35, spinning liquid being fed through a stationary rubber pipe 36 having a conical end entering a conical aperture in the rotary spindle 34.  The filling vessel 12 has an extension 2 engaging by means of flange 3 in the mouth 4 of the precipitation vessel.  The mouth 4 is covered by a rotatable disc 5 under which surplus precipitation liquid may flow.  An inner stationary tube 6 is secured in the extension 2 by ribs 13, 14, 15, Fig. 2.  These ribs form apertures 7 which cause the precipitation liquid to flow through the extension 2 substantially axially and without rotation.  A guide tube 8 rotates within the stationary tube 6 being secured frictionally to the rotating vessel by leaf springs 19, 20 engaging a recess 21. A stop in the recess 21 prevents slipping of the spring 19 if the friction should be insufficient.  The tubes 6, 8 extend to a level slightly below the level of the liquid in the vessel 12.  The bore of the guide tube 8 may be made sinuous to reduce the swirl of the column of liquid therein without diminishing the cross-section available for threading.  A siphon tube 40, Fig. 4, permits the lower half 30 of the precipitation vessel to be filled preparatory to starting spinning.  In a Specification laid open to inspection under Sect. 91, the arrangement according to Fig. 4 is described in closer detail. The guide tube through which the thread passes from the rotary to the stationary vessel is stated to be kept in position by three stays.  Excess spinning liquid passes out at the connection between the part 1 of the rotary vessel and filling vessel 12, and may be collected by an enclosing jacket (not shown).  The shape of the lower portion 30 is said to be such that when the lower vessel is open it may be emptied by centrifuging the liquid out over the sides. If desired instead of lifting the upper portion 1 of the rotary vessel, the lower portion and the electromotor may be lowered, a shutting-off device being arranged in the tube 41. This subject-matter does not appear in the Specification as accepted.
