Title: Semi-conductor adjustable band pass filter
IPC: H03H1/02
Filed: 1962-03-13
Abstract: 954,532. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. March 13, 1962 [March 24, 1961], No. 9618/62. Heading H1K. Unitary semi-conductor devices are constructed which act as RC band-pass filters. The embodiments described conform to the circuits illustrated in Fig. 3A and in Fig. 8 (not shown). (The circuit of Fig. 8 is like that of Fig. 3A but has a series capacitor inserted at point 3). Semi-conductor materials which may be used are silicon, germanium, silicon carbide, and the stoichiometric A<SP>III</SP> B<SP>v</SP> compounds. As particularly described the embodiment illustrated in Fig. 5 is made from a single crystal wafer of N-type silicon in which P-type regions 14, 18 are formed by indiffusion of aluminium. Ohmic contacts are fused to each P-type region and to the N-type region at the ends of the wafer, in the positions shown. The two PN junctions formed are reverse biased by external supplies and act, with the adjoining semi-conductive layers, as distributed resistor/capacitor combinations conforming to the circuit of Fig. 3A. The band-pass characteristics of the device can be adjusted by varying the reverse bias applied to the two PN capacitors. The embodiment of Fig. 7, as particularly described, is also made from a single crystal wafer of N-type silicon. One end of the wafer is masked and aluminium is diffused into the exposed end to convert it to slight P-type conductivity. In subsequent steps aluminium is selectively diffused into part of the upper face of the remaining N-type region to produce a heavily doped P-type region 48, and arsenic is diffused into part of the lower surface of the first P- type region 44 to form an N<SP>+</SP> region 52. Ohmic contacts are provided to each region in the positions shown, and the device when connected with the external bias supplies shown conforms to the circuit of Fig. 8. By a rearrangement of the external circuitry a single bias supply may be employed, as described with reference to Fig. 9 (not shown).

Title: Improved apparatus for heating liquids
IPC: F24H1/00
Filed: 1924-04-16
Abstract: 235,990. Lambert, A. J., and Kerr, G. C. April 16, 1924. Boilers.-A plurality of cells 10, 11 containing liquid are arranged side by side in a horizontal layer or layers and are connected together by passages 17 - - 30 of small capacity in such a manner that the liquid passes successively through all the cells. The cells are so proportioned that the depth of each cell is not greater than its diameter or the length of its greatest dimension in plan if non-circular. The lid of each cell is in contact with or very close to the surface of the liquid. Sets of cells and their interconnecting passages may be formed in one piece as a die-casting. In the example, shown, the cells 11 in the lower layer fit upon the base of the cells 10 in the upper layer and are heated by burners 37. A vent-hole '33 is provided in each cell. In a modification the cells are lozenge-shaped in plan, those in the lower layer being staggered relatively to those in the upper layer. Reference has been directed by the Comptroller to Specifications 15541/91, 17614/01, and 163/05.

Title: Method of and apparatus for producing chlorine dioxide for immediate use
IPC: C01B11/02
Filed: 1960-03-18
Abstract: In a continuous process for the production of chlorine dioxide, for example from a solution of a chlorate and a reducing agent, wherein a generator is continuously fed with liquid reactants and the evolved chlorine dioxide is passed, together with a predetermined minimum quantity of inert diluting gas or vapour, to an apparatus where it is utilized, the inert gas or vapour is drawn into the reactor through a throttle by gas propulsion means in such manner that a partial vacuum exists in the reactor and apparatus, said partial vacuum serving to introduce the reactants into the generator; upon a failure of the partial vacuum, the supply of reactants to the reactor is stopped, thus stopping the evolution of chlorine dioxide. Upon such failure, the liquid contents of the generator may additionally be discharged to a tank below the generator, from which chlorine dioxide is vented to the outside atmosphere. In one form, the chlorine dioxide is absorbed by liquid trickling down a tower, and the remaining inert gas is recycled via the throttle. The liquid supplied to the tower may be so arranged as to form a seal, such that on a failure of the liquid supply the seal, and thus the vacuum, is broken by atmospheric air. In this form the atmospheric air may so flow as to sweep the surface of the reacting liquids and thus remove chlorine dioxide, and the air may be at least in part then vented to the outside atmosphere.

Filed: 1992-01-08
Abstract: PURPOSE:To increase the adjustment quantity of azimuth and to implement the adjustment with high accuracy providing a drive direction regulation means regulating the running direction of a magnetic tape to a holder with a prescribed distance from a magnetic head. CONSTITUTION:Guides 6b, 6b and guide grooves 6c, 6c form a running direction regulation means A of a tape 4. The tape 4 pressed by capstans 3, 3A with pinch rollers 2, 2A is driven by the rotary drive of the capstans 3, 3A in the recording or the reproduction mode. Then the drive direction of the tape 4 is regulated by the guide 6c, skided on the head 5 and recorded and reproduced by a magnetic element E. In the azimuth adjustment process, the relation of azimuth adjustment quantity =L1/2Xtantheta' is in existence and since the azimuth adjustment quantity is proportional to the distance between the guide 6b, the azimuth adjustment quantity is extended. Thus, the adjustment accuracy is improved and an azimuth loss is reduced.
