Title: Read-only memory
IPC: G11C17/02
Filed: 1963-10-08
Abstract: 1,013,879. Permanent data stores. RADIO CORPORATION OF AMERICA. Oct. 8, 1963 [Oct. 23, 1962(3)], No. 39693/63. Heading G4A. A read-only memory comprises a plurality of transformer cores each having two apertures with a central leg therebetween, a plurality of primary windings each. extending through one aperture of each core, there being an individual secondary winding wound round the central leg of each core. As shown, Fig. 1b, a read-only memory comprises ferrite transformer cores 10, 12, 14 each having two apertures 24, 26 with a central leg 16 therebetween. An insulating sheet 36 carries a printed primary winding 30 which may be initially formed as a ladder network, holes 46, 47, 48 being punched out to form a conductive path through one only of the two apertures 24, 26 of each core. The individual secondary windings 54 may be printed as spirals on an insulating sheet 56. In operation, the application of a signal to the primary 30 causes, by transformer action, output pulses in the secondaries 54 which are of one or the other polarity, representing " 1 " or " 0 " depending on which aperture 24, 26 of the corresponding core is effectively threaded by the primary 30. By arranging that no hole is punched in either of the arms of the printed winding 30 through a particular core, that core will produce no output signal since the input signals cancel and such a signal can represent a third component if it is desired to store ternary data. The memory is assembled by removing transformer core arms 22 and threading on the central legs 16 the desired number of primary winding sheets 36, and the secondary winding sheet 56.

Abstract: 1,010,430. Cyphering and decyphering. ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT. Nov. 9, 1961, No. 40173/61. Heading H4P. In a cyphering system each " clear " letter, from either a keyboard M or a tape LS, Fig. 1, is converted C into a number of pulses equal to the serial number of the letter in the alphabet, a " key " letter, e.g. from a key-tape B, is similarly converted, and the two pulse trains are added (modulus 26) in a counter D, the resulting sum (modulus 26) being converted E into a " cypher " letter having a serial number in the alphabet equal to the sum (modulus 26), and this " cypher " letter is transmitted F.G.N. in a telegraphic code to a distance. For decyphering a similar arrangement is used except that the " key " letter is subtracted. The system described also includes a counting H and programme J device which inserts two " space " signals between each block of five " cypher " letters and " carriage return " and " line feed " signals between each group of ten blocks. In the decyphering arrangement of the equipment shown a device I is provided which detects any technical signals such as " line feed ", " space " and the line, and stops the feed of key letters from the tape B since such technical signals form no part of the cyphered text. (The apparatus only cyphers letters and each cyphered letter is a further letter). Also, as described, the letter " W " is replaced by the letters "VV", thereby leaving W free to be used as a space symbol.

Abstract: 1,132,558. Slide projector. AGFA - GEVAERT A.G. Sept. 8, 1967 [Sept.10, 1966], No.41096/67. Heading G2J. The invention relates to a slide projector having two projection systems and means for fading in one system as the other is faded out, the two systems being fed from diametrically opposite sides of a common circular rotary slide magazine. As shown in Fig.2, a circular magazine 2 is mounted on the projector housing 1 and slides 4 are in both gates 46 and 47, the slide in gate 46 having been projected. In operation, a control shaft 10 is rotated causing a pin 9c on a control disc to raise a pivoted lever 11 which lifts the slide 4 in the gate 46 back into the magazine compartment 2b. An extension 3b on the mounting spindle 3 for the magazine 2 is moved by a cam in the control disc so as to move the magazine 3 so that a new slide compartment 26 is aligned with the gate 46, the other side of the magazine aligned with gate 47 being held stationary by a locking arm 19b engaging with one of a number of latching projections 2c on the base of the magazine circumference. The pin 9c then lowers the lever 11 causing a fresh slide to be placed in gate 46. A control cam 17a on the control disc releases the locking arm 19b and causes the other end 19a thereof to engage one of the latching projections 2c. A control curve 17b now pivots the diaphragm blades 25 and 26 so as to fade out the right hand projection system and fade in the left-hand system containing the fresh slide. The slide in gate 47 is now changed in a similar manner by a control pin 9b acting on a pivoted lifting lever 12.

Title: Improvements in and relating to optical arrangements
IPC: G03B41/00
Filed: 1968-08-29
Abstract: 1,244,193. Optical arrangements for cameras; lenses. RICOH K.K. Aug.29, 1968 [Sept.11, 1967(2)], No.41201/68. Headings G2A and G2J. In a camera for producing a number of exposures on the picture area of a photo-sensitive sheet, the optical arrangement is in the form of a first lens 11 (or 21) having a curved focal plane at which the image I is formed, an aperture 13 (or 23) adjacent to or within the first lens and movable in a plane perpendicular to the optical axis, and a second lens 12 (or 22) having a plurality of microlens elements on the near face which focus on the further face. In the first form, shown in Fig.2, the second lens 12 has a focal plane of the same curvature as the image I, so that the perpendicular distance between each portion of the image I and the corresponding point on the second lens is substantially the same. The image I is split into discrete portions, each of which is sharply focused upon the photo-sensitive material 14 mounted on the rear surface of lens 12. The aperture can be displaced into various positions, e.g. by seven equal steps in both vertical and horizontal directions, each of which will produce a record on a different portion of the photo-sensitive sheet 14. In the second form, shown in Fig.3, the second lens has its mirco-elements disposed in a plane, and not in a curve as in Fig.2. The focal length of the micro-lens elements varies according to the distance of the element from the image plane I. Thus the element at a distance a from plane I will have a different focal length from the element at a distance aa. The focal length is such that each element produces a sharply focused image on the photo-sensitive sheet 24 on the further face of lens 22.

Title: Semiconductor device
IPC: H01L23/051
Filed: 1960-11-30
Abstract: 904,850. Semi-conductor devices. HUGHES AIRCRAFT CO. Nov. 30, 1960 [Dec. 22, 1959], No. 41222/60. Class 37. A junction-type semi-conductor device has parallel, flat electrodes separated by insulating material which encapsulates the semi-conductor body. A diode is manufactured by bonding an electrode 23 to an N-type silicon wafer 26 and alloying a piece of aluminium 25 to the other side of the wafer to form a PN junction. After cleaning the junction with acetic acid, nitric acid and water a small quantity of insulating material 28 which becomes plastic at or about the normal operating temperature of the device is flowed over the junction region. Suitable materials are high-purity glasses, e.g. one containing 24% As, 67% S, 9% I, with up to 25 parts per million of sodium, manganese, silicon, copper and iron; or glasses including As, S and Se; or As, S and Tl. The assembly shown in Fig. 7 is then placed in a press 31 and a quantity of insulating material 32 sufficient to cover the device is added and compressed to form a solid body. Suitable materials are fluorocarbons and polyfluorocarbons which are elastic at the normal operating temperature of the device. After compression the base 34 of the press is raised so that part of the insulating body protrudes (Fig. 9). This part is then shaved or ground away, leaving a clean surface of aluminium. Base 34 is then lowered and an upper electrode 22 is bonded to the top of the device using an epoxy material containing metallic (e.g. gold) flakes or by coating the electrode with gold and tin and heating above the gold-tin eutectic temperature. The lower electrode 23 is preferably of non-magnetic material, e.g. gold-clad molybdenum, and the upper electrode 22 of magnetic material, e.g. gold-clad iron or nickel iron, so that the orientation of the diode may be determined. A transistor (Fig. 4) may be produced in a similar manner. A mesa-type junction structure is formed on wafer 42 and leads 44, 45 attached to the mesa 46. Glass 47 and insulating material 48 are then applied as before, except that leads 44, 45 are coiled or angled upwardly through material 48 so that when the surface is shaved a relatively large area of metal will be exposed. Electrodes 51, 52 form segments of a circle and are separated by a volume of insulating material. An indexing tab of material is allowed to protrude at one side to determine the orientation of the transistor (Fig. 3, not shown).

Abstract: 1,156,935. Automatic temperature control. L. A. KELEMEN. Sept. 15, 1966, No.41295/66. Heading G3R. An arrangement for controlling the temperature of an electrically heated article comprises means whereby the main automatic control circuit can be short-circuited for a predetermined time after the article has been switched on in order to allow the article to reach its operating temperature rapidly before the main automatic control circuit becomes operative. Closure of a switch 3 allows the heating element 4 of an electric blanket 5 to be supplied from a source 1, 2 by way of an indicating lamp 9, normally closed contacts of a bi-metal switch 8 and the heating element 10 thereof. After a predetermined time the bi-metal element 11 of the switch 8 is heated sufficiently to open the contact whereafter the heating element 4 of the blanket is supplied by way of a device such as a thyristor 13. During normal operation deviation of the temperature of the blanket 5 from normal causes a signal to be developed in a bridge circuit which includes the heating element 10, the blanket heating element 4 and resistors 18-20. This signal is applied to the primary winding 21 of a transformer 14 thus to control the thyristor 13 by way of a transistor 23 and a bi-directionally conducting device such as a disc 12. The resistor 18 is variable to set the desired blanket temperature and a lamp 28 indicates the blanket receiving a supply by way of the thyristor 13.
