Title: Improvements in or relating to frequency selective devices
Inventor: COLCHESTER CHRISTOPHER DERING
IPC: G01S1/02
Filed: 1955-05-18
Abstract: 797,891. Frequency measurement. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 27, 1956 [May 18, 1955], No. 14339/55. Class 37. [Also in Group XL (c)] A critically frequency selective device for analysis of a spectrum of high-frequency signals comprises an elongated specimen of high nuclear gyro magnetic ratio threaded longitudinally by an alternating magnetic field generated by high-frequency input signals, and at right angles thereto by a magnetic field constant with time and uniformly variable along the length of the specimen; with a pickup coil disposed adjacently thereto with its axis at right angles to the axes of both the magnetic fields and adapted to be positionally varied along a predetermined path longitudinally of the specimen so that at each position there is a different value of constant field in the specimen, and consequently in the value of Larmor nuclear precession frequency, whereby the pickup coil develops at each position in the range a signal representing the input signal frequency component corresponding thereto, which may be oscillographically displayed as a spectrum while the path over which the pickup coil moves is calibrated directly in frequency values. The output frequency spectrum of a frequencymodulated continuous wave (Doppler) radar energizes (Figs. 1, 2) a coil 6 wound on a curved stoppered tube 4 containing water admixed with hydrogen and disposed in a gap between curved non-parallel pole pieces of a permanent magnet arranged so that the intensity of the field normal to the tube axis decreases linearly from the lower to the upper end. A pickup coil 8 with a ferromagnetic core is mounted on arm 9 and a voltage coil 12 is similarly mounted on arm 13; the coils being oscillated at e.g. 50 c/s. in arcs parallel to the specimen, so that coil 12 generates a voltage instantaneously representative of the position of the pickup coil, which after amplification deflects the beam of C.R. oscillograph 15 along one co-ordinate, while coil 8 generates output signals when a frequency component of the input coincides with the nuclear resonant frequency of the specimen at the corresponding pickup coil position, which after amplification deflects the beam along the other co-ordinate, so that the display indicates the frequency distribution of the input signal. In a simplified form the amplified output of coil 8 may be indicated while the arm 9 may carry a pointer over a calibrated frequency scale. The output voltage of coil 12 may be applied to deflect the oscillograph radially in synchronism with its movements, and the output signals of coil 8 may be applied to brighten the oscillograph trace. Coil 12 may be rotated about its own axis to produce a signal characteristic of its position along the specimen.

Filed: 1970-03-25
Abstract: 1275183 Transistor gating circuits RCA CORPORATION 25 March 1970 [2 April 1969] 14381/70 Heading H3T [Also in Division H1] The transconductance of an n channel IGFET 16 is made equal to that of a p channel IGFET 14 by making the channel width-tolength ratio of the former device perpendicular to the direction of current flow proportionately less than that of the latter device. At the same time the gate/drain capacitances of the two devices are made equal by compensating for any additional channel width of the p channel device 14 by means of an extension 55 of the gate electrode 54 of the n channel device 16 which overlaps the drain region 47 by a relatively large amount "D" as compared with a smaller corresponding overlap "d" for the p channel device 14. Alternatively the capacitance matching may be achieved by providing an additional separate capacitance between the gate and drain of the n channel device 16. In the switching circuit shown the sources and drains of the two devices 14, 16 are respectively connected to provide output terminals 67, 68 across which a circuit to be controlled is connected. Gate voltages of equal magnitude but opposite polarity are applied simultaneously to the two gate electrodes 54, 62 to turn the devices on or off, thereby to produce the switching characteristic of the circuit. The two devices may be integrated in a common Si body as shown, or may be discrete devices.

Title: Photographic material
Inventor: AUDRAN ROGER GASTON LOUIS
IPC: G01T1/08
Filed: 1966-04-01
Abstract: 1,137,745. X-ray film; film dosimeter. EASTMAN KODAK CO. 1 April, 1966 [1 April, 1965], No. 14441/66. Heading H5R. [Also in Division G2] A photographic material particularly sensitive to ionizing radiation comprises a layer of a sensitive silver halide emulsion in open cell cellular form in which 10-95% of the material is void. The term " open cell cellulose form " means the cells are interconnecting or have thin walls easily rupturable by processing solutions. The emulsion may be supported in the cellular form by a hardened colloidal binder, or by coating it on to the cellular surfaces of a cellular synthetic polymer matrix. A specified binder is gelatine, which may contain a compatible synthetic polymer, e.g. polystyrene, a styrene/butadiene copolymer or polyethylacrylate, and which is hardened e.g. with formalin. Specified resin matrices are those formed from polyethylene, polypropylene, polystyrene, styrene-butadiene copolymers and polyvinyl chloride, and foams of diene resins and condensation polymers. The cellular matrix surfaces may be sub-coated with a copolymer of e.g. methyl methacrylate/acrylic acid/gelatine, methylacrylate/vinylidene chloride/itaconic acid, or ethyl acrylate/acrylonitrile acrylic acid. The thickness of the cell-walls may be less than 20Á, the cell diameter may be 30Á- 1mm., and the layer may be 2mm.-2cm. thick and may contain 3-15 mg./cc. of combined Ag. The emulsion may contain a foaming agent and the usual additives. The material may be formed by incorporating a gas, e.g. air or N 2  into the emulsion, e.g. by agitation or by passing the gas through a porous plate into the emulsion, by mixing the emulsion with a compatible solvent and treating with a second solvent which coagulates the emulsion and dissolves the first solvent, or by impregnating a foam matrix with the emulsion. When using the material for determining quantities of ionizing radiation the exposed material is developed, fixed, dried and the quantity of Ag therein determined by e.g. X-ray fluorescence spectroscopy, by dissolving out the Ag, or by saturating the material with a liquid having a refractive index similar to that of the cellular support and thereafter measuring the optical density.

Title: Improvements in or relating to microphone assemblies
Inventor: ROBERTON JAMES SAMUEL PATERSON
IPC: H04R1/22
Filed: 1952-06-13
Abstract: 728,364. Mouthpieces; sets. STANDARD TELEPHONES & CABLES, Ltd. June 5, 1953 [June 13, 1952], No. 14958/52. Class 40 (4). [Also in Group XXXVIII] In a microphone assembly the microphone unit is coupled to the atmosphere by a horn system which is designed to have a lower coupling efficiency at the major mechanical resonance frequency of the vibrating elements of the microphone than at any other frequency. The coupling efficiency is also designed to rise with frequency from the lower value at an average rate of 9 db. per octave for not less than one octave. In a headset, Fig. 1, a receiver 3 and a microphone unit 5 are enclosed in a casing 2 attached to a head-band 10 by a ball-and-socket joint. The microphone capsule 5 communicates through a duct 6 in a moulded cover 1, a tubular elbow 7, and a flexible joint 8 with a horn 9 which can be adjusted to come opposite the mouth of the user. Acoustic damping which may comprise a helical spring as in Specification 716,801 is inserted in the common bore of ducts 6, 7, 8 in order to prevent the setting up of standing waves. A carbon granule microphone, Fig. 2, has the granule chamber housed in a recess 16 in the casing 15. Electrode 18 is mounted on a rim-clamped diaphragm 24 and penetrates into the chamber through a flexible membrane 17 of one or more layers of silk. The fixed electrode 20 is located in a recess in an insulating ring 19 and is held in position by a retaining washer 21 which is secured by swaging the edge 22 of the recess. A stalk 23 which is. internally bored provides a means of filling the granule chamber and also one of the electrical terminals. The front cover 26 is shaped to conform to the diaphragm so that the air cavity 27 above the diaphragm is reduced to a minimum and since this cavity acts as a shunt, the power absorbed is also reduced to a minimum. An undesirable rise in the frequency characteristic in the second octave below the major resonance frequency which results from this arrangement is reduced by a hole pierced in the diaphragm, and variations in mechanical impedance of the vibrating elements are swamped by the high acoustic impedance presented by the horn. Typical response curves are described with reference to Fig. 4 (not shown). An alternative headset arrangement having the receiver over one ear and the microphone over the other is described with reference to Fig. 5 (not shown), and the invention is stated to be applicable to moving iron, moving coil, or crystal microphones.
