Title: An analog to digital converter circuit
IPC: H03M1/00
Filed: 1970-01-14
Abstract: 1,261,003. Analogue to digital converters. TEKTRONIX Inc. 14 Jan., 1970 [24 Jan., 1969], No. 1779/70. Heading G4H. An analogue to digital converter has a number of comparator circuits, each comprising two transistors 10, 11; 12, 13 etc., each comparator circuit being fed current via a transistor 28 to the common emitters of transistors 10, 11, etc. The analogue input may be fed to the converter via an emitter follower amplifyer comprising a transistor 76 or 54 (two inputs). In the absence of an anologue input, the transistor pair 10, 11 have the same base bias and both carry the same current, the transistors 12, 14, . . . 26 one non- conducting, and transistors 13, 15 ... 2) are conducting. When a signal of 10À5 V. is applied transistor 10 becomes non-conducting, resulting in an increase of base bias voltage to transistor 122 and a pulse output at 162 (current flows). When a signal of 11À0 V. is applied, transistor 10 becomes conducting, which causes 11 to become non-conducting. This switches off the input on 162 since current now flows through resistance 102, and at the same time current can no longer flow through resistance 104 since both transistors 11 and 12 are non-conducting. This produces an output at 144. Successive increments in input voltage thus cause the output signal to move down the outputs, 162-180. Transistor 49 acts as a temperature stabilizer for the current supplied to transistors 122, 124 ... 140. Transistors 196 and 200 provide temperature stability and #-current gain stability for the current supplied to transistors 10, 12 . . . 26. The unit may be made as a monolithic integrated circuit.

Title: Improvements in and relating to Electromagnetic Switches.
IPC: H01H71/24
Filed: 1917-02-06
Abstract: 112,996. British Thomson - Houston Co., (General Electric Co.). Feb. 6,1917. Electro-magnetic switches.-The single winding contactor of the lock-out type described in Specification 23544/14 is provided with a series holding-out winding 33 in addition to the shunt winding 10. The main armature 16 which is pivoted at 17 carries the movable contact-member 20 pivoted at its upper end and has a polepiece extension 26 located between the upturned fixed pole-piece 27 and the fixed pole-piece 12 so that normally the extension is equally and oppositely attracted by the fixed pole-pieces. The armature 16 has fixed upon it an extension 35 carrying an armature 36 co-operating with the pole-piece 32 and adjustable on a stem 37 in relation to the pole-piece, the stem itself being adjustable to ensure the balanced position of the armature 26. The series coil is in two parts, the additional part being used, if desired, to hold out the switch from automatic action. In operation, the energization of the winding 10 causes the attraction of the subsidiary armature 29, which is mounted on the pivot 17, and the consequent compression of the spring 30 which tends to move the switch to the closed position. This movement, however, is prevented by the holding-out magnet 32 until the series current drops sufficiently, whereupon the spring 30 moves the armature 26 out of the balanced position and the contact-member is wiped home by the attraction of the pole-piece 27. Specification 107,289 also is referred to.

Title: Method of producing straight beams of substance within an enclosed space at a high vacuum
IPC: H05H1/02
Filed: 1962-01-19
Abstract: 923,332. Nucleonics. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Jan. 19, 1962 [Jan. 21, 1961], No. 2122/62. Class 39 (4). A method of producing, within an enclosed space at a high vacuum and from a substance which is gaseous at ambient temperature, a straight beam of substance which has a density higher than 10<SP>-10</SP> g./c.c., the beam being cylindrical and having small transverse dimensions relative to its length, comprises effecting a controlled condensation of the gaseous substance in a reservoir outside the enclosed space and, when the drops thus formed have reached appropriate dimensions, injecting the mixture of drops and gas towards the enclosed space under such conditions that the stream of drops is separated to a substantial extent from the gas and is then introduced into the enclosed space. In Fig. 1, the main chamber 1 has one end connected to an enclosed space 2 which is cooled by boiling liquid hydrogen and in which is placed an auxiliary reservoir 3; at its other end the main chamber is connected to a terminal chamber 4, and both chambers are evacuated through ducts 5 and 6. The auxiliary reservoir 3 can be connected to hydrogen and tritium reservoirs through valves 7, 8 and can communicate with the remainder of the apparatus through a quick-acting valve 9. The reservoir 3 is initially filled with tritium (e.g.t o a pressure of 10<SP>-1</SP> mm.) and then placed in communication with the hydrogen supply which allows the hydrogen pressure to rise for a short time above the pressure corresponding to the threshold of condensation around electric charges and then to fall slightly below the threshold, Fig. 2 (not shown). Whilst the pressure is above the threshold, drops form around ions produced by the radio-activity of the tritium, and afterwards the drops start to increase in size. When the drops reach the required size, e.g. after 0.1 second, the valve 9 is opened to allow a stream of gas and drops to be injected towards the main chamber. Two collimators 10, 11 connected through tubes 12, 13 to vacuum pumps enable most of the gas to be removed from the stream before it reaches the main chamber. If a gas column is required in the centre of the main chamber the stream of drops can be evaporated in situ by electron bombardment. The density of the stream may be about 10<SP>-6</SP> g./c.c. using drops of about 10<SP>-3</SP> cm. in diameter.
