Title: Microphone unit
IPC: H04M1/60
Filed: 1979-11-30
Abstract: A microphone unit for a telephone handset includes an electret microphone (3) mounted on a first member (4) which is in turn carried by a printed circuit board (2) which forms part of an amplifier circuit for the microphone unit. The major heat dissipating components of the amplifier are a bridge rectifier and a resistor and one terminal of each of these components is connected to terminals (11). The terminals (11) are made from brass which has good heat conducting properties and form heat sinks for the bridge rectifier and resistor in cooperation with enlarged lands on the printed circuit board (2). This construction uses the terminals which have to be provided to connect the microphone unit to the telephone line for the additional purpose of conducting heat from the bridge rectifier and resistor. Thus the use of components having a higher heat dissipating capacity or of a separate heat sink is avoided. <IMAGE>

Patent GB-2048471-A (GB)
Title: Determination of metal in gas
IPC: G01N21/74
Filed: 1980-04-11
Abstract: To determine the metal content, e.g. the lead content, of a gas such as air, the gas is passed into the cavity (5) of a cylinder (1) having an electrode (3) disposed along its axis. A high electrical potential is applied between the cylinder (1) and the electrode (3) by means of a direct current generator (8), and the resulting electrostatic field causes particles dispersed in the gas to be deposited upon the walls of the cavity (5). The cylinder (1) is then heated to vaporise the deposited particles, and the metal content of the vapour is then determined by an electrothermal atomic absorption method or by an equivalent spectrometric method. <IMAGE>

Title: Skein banding
IPC: B65B13/02
Filed: 1980-06-27
Abstract: A machine for wrapping a band around a skein of threadlike material comprises pocketed units (25a to 25l) connected to a belt (26). An entrance to each pocket formed by an endless belt 27 is opened and closed by use of a movable guide roller (31). A band (12) printed in a unit 18 and glued at 21 is placed into the pocket between the skein (11) and an edge wall of the pocket, and the pocket is then closed. As the unit 25a travels round a fixed belt extending across the path of the conveyor 26 causes rotation of the belt 27 so that the band is wrapped round the skein and opposite ends of the band (12) are glued to one another. The skein remains in the pocket while the glue dries. Finally, the pocket is opened and the banded skein drops free onto an outlet conveyor (32). <IMAGE>

Title: Power factor control for induction motor
IPC: H02J3/18
Filed: 1981-06-03
Abstract: A system of controlling the voltage applied to a three phase alternating current induction motor to minimise electrical losses and achieve electricity savings both in starting and running the motor and extending motor life through maintaining lower frame temperatures when the motor is running involves correlating motor torque and power factor, monitoring on each phase input current and voltage, with such voltage being referenced between phase and generated star point, and adjusting applied voltage to compensate for changes in load. <IMAGE>
Patent GB-2085094-A (GB)
Title: Hydraulic motors
IPC: F03C1/24
Filed: 1981-07-01
Abstract: A hydraulic motor has a cylindrical stator portion 3 which has a number of peripheral reentrant portions 18. In each reentrant portion is a roller element 19. The rotor 2 has a surface 23 which defines with the periphery of the stator portion, a number of generally crescent-shaped spaces. The stator and rotor are provided with passages 14, 15, 17, 21, 22 and 16, 20 respectively which cooperate cylically during rotation of the rotor to conduct hydraulic fluid to and from the reentrant portions. Pressurised hydraulic fluid is conducted to a reentrant portion only when the distance between the surface 23 and the stator in the proximity of the reentrant portion is increasing. This urges the roller disposed in that reentrant portion against the surface 23, thus causing the rotor to rotate. A hydraulic motor driven electric generator is also provided by the invention. <IMAGE>

Title: Doppler Speed-log Apparatus
IPC: G01S15/60
Filed: 1982-02-01
Abstract: Doppler apparatus for determining the velocity of a marine vessel through the water does not need to compensate for sound velocity variations. A transducer array (170) of equally spaced electro-acoustic elements, with each element being tilted at a fixed depression angle with respect to horizontal, radiates (at 180, 210) forward and aft sonar waves and receives (at 190, 200) the resulting echos. The frequencies of the Doppler- shifted signal inputs derived from the echos are substracted one from the other using a frequency difference counter to produce a count quantity proportional to the velocity of the vessel. The accuracy of the quantity is independent of the speed of sound and transmitter frequency. By appropriate time scaling of the count period, the count quantity can be made to be expressive of the velocity. <IMAGE>

Title: Making printed circuit boards
IPC: B32B15/08
Filed: 1982-04-02
Abstract: A printed circuit board having a high-resolution circuit pattern is made by vapour depositing a thin pinhole-free metal film 50 on an aluminium carrier sheet 51, applying a circuit pattern (e.g. photoresist) mask over the film 50, depositing (e.g. by electroplating) a (copper) circuit pattern 53, removing the mask, laminating a substrate 54 to embed the circuit pattern 53, and removing the carrier 51 and film 50 to leave the pattern 53 exposed flush with the substrate surface. The substrate is preferably a glass-epoxy prepreg sheet. To provide mechanical bonding to the substrate a layer of dendritic or nodular copper may be deposited on the circuit pattern 53 before the mask is removed. Chemical bonding of the circuit pattern may be provided by vapour depositing thin coatings of zinc and silicon dioxide after mask removal. <IMAGE>

Abstract: A unit wherein oil vapour and moisture are removed from compressed air in a vehicle braking system comprises a housing with an air inlet 14 and outlet 16, the air flowing through annular space 34 and outwards through filter 18 to impinge on the housing wall, where condensation occurs, then down an annular gap between the wall and sleeve 30. A steel spring 44 covers holes 42 to serve as a bypass which is opened by rising pressure if filter 18 clogs, the bypass air still impinging on the housing wall. A two-stage valve 48 discharges liquid from the bottom of the housing (Figure 2 not shown). When the pressure in the housing is high lip (59) deforms to let liquid into valve chamber (64), and when the pressure reduces the valve member (60) is thereby lifted to discharge liquid through outlet (62). <IMAGE>
