Title: Electromechanical transducer for relief display panel
IPC: G09B21/00
Filed: 1978-08-02
Abstract: A reading plate has an array of holes in its surface. Rounded ends of rods project selectively through these holes by the action of a set of bimorphous piezoelectric reeds, to which they are coupled. Each reed is connected to a source of voltage which can assume two distinct values as a function of an electrical control signal in order to make the piezoelectric reeds bend in one direction or the other. The rods are distributed in groups of six and arranged in each group according to the conventional arrangement of dots of a Braille character. The transducer can thus provide a relief read-out panel for a pocket electronic calculator for the blind. Methods of using these transducers for recording and readout of magnetic tape with data in Braille-generable form and equipment incorporating them are disclosed. <IMAGE>

Title: Controlling burner fuel supply in fluid heating apparatus
IPC: F23N1/08
Filed: 1979-08-07
Abstract: The flow rate of the fluid to be heated is detected as a pressure difference by a venturi arrangement 38, which is converted to a force by a pressure receiving unit 58 and a balance mechanism consisting mainly of a spring 83 and a lever 77. The latter applies the force to the loading spring of fuel control valve 70 so that fuel is regulated approximately in proportion to the flow rate of the fluid supply. Accordingly the rise of the temperature of the fluid to be heated is controlled to a set value despite variations in the flow rate. The pressure difference at the venturi is also used to control a valve 34 in the fluid supply line and a valve 56 in the fuel supply line. An adjustable valve 45 is provided in a line bypassing the venturi. The fluid is heated with the heat of combustion of a burner through a heat exchanger 44 such as in an instantaneous gas water heater. <IMAGE>

Title: Cartridge assembly
IPC: G03B17/26
Filed: 1980-08-04
Abstract: A photographic film cartridge assembly includes an opaque casing with an exposure window 44 in one wall and a film unit 10 with photographic film. The film unit has an exposure region and is mounted in the casing for movement relative to the casing in a film advancing direction such that successive portions of the exposure region are aligned with the exposure window. A cover member 14 including an opaque region 52 is mounted in the casing between the wall and the film for movement independent of the film unit. The cover member is movable between a closed position, in which the opaque region is aligned with and covers the exposure window, and an open position, in which the opaque region is out of alignment with and uncovers the exposure window. A notch 38 in the film unit and a ramped tooth 66 on the cover member, are engaged to inhibit movement of the film unit in the film advancing direction when the cover member is in its exposure window covering position. When the cover member is moved to its exposure window uncovering position, the tooth and notch subengage to allow the film unit to be advanced. <IMAGE>

Patent GB-2080650-A (GB)
Title: Very low current pierce oscillator
IPC: H03K3/354
Filed: 1981-07-07
Abstract: A very low current Pierce oscillator has two pairs of complementary field-effect transistors (FET's) and a two-terminal quartz crystal. The gates of the first complementary FET pair are coupled through individual capacitors to one terminal of the quartz crystal, their drains being connected together and to the other quartz crystal terminal. Current flow through the crystal oscillator is minimized by a novel oscillator bias loop connected between the gates of the first FET pair. Amplification is provided by the second FET pair which have a commonly connected drain comprising the oscillator output node. The gates of the second FET pair are each connected to a respective one of the gates of the first FET pair. The oscillator bias loop minimizes the source-to-drain current through the first FET pair by reducing the P-channel FET gate voltage in response to the source-to-drain current. The oscillator bias loop assures reliable start-up by permitting the oscillation of the source-to-drain current to increase freely to some large magnitude and then operates to reduce the amplitude of the oscillation and also the dc bias level of the current to an equilibrium condition. Means are provided for preventing elements within the oscillator bias loop from overloading the oscillator or otherwise preventing the initiation of oscillation at start-up.

Title: Curtain pleating tape
Inventor: AKTINS REGINALD CHARLES
IPC: A47H13/16
Filed: 1981-12-22
Abstract: Band 10 which has pockets 11, 12, 13 for curtain hooks (not shown) is formed with first draw cords 14, are adjacent each edge of the band 10, and second draw cords 15, 17, also one adjacent each edge of band 10, these two sets of draw cords being alternatively shortenable according to the type of pleat required. Shortening of the first cords 14 serves to produce pencil pleats, that is to say regular, closely adjacent pleats along the entire length of the tape 10. Since floating portions 16 of draw cord 15 are longer than corresponding floating portions 18 of draw cord 17 shortening of the second cords 15, 17 serves to produce french pleats in fan- shaped configuration (i.e. alternate fan-shaped pleated sections and intervening non-pleated sections) along the length of the tape. <IMAGE>
