Title: Improved safety pressure reducing regulator
Inventor: FALLOW MERETON R
IPC: F16K17/20
Filed: 1983-03-07
Abstract: A safety pressure reducing regulator for use in systems operable by pressurized gas incorporates multiple safety features which preclude excessive pressure buildup in the system and provide protection against catastrophic failures. The regulator includes primary and secondary regulator stages leading to a pressure control chamber (60) which provides the operating pressure for the system. The primary regulator stage reduces the inlet gas pressure to an intermediate level. The secondary regulator stage regulates the supply of the pressurized gas at the intermediate pressure to the pressure control chamber to maintain a desired operating pressure therein. A flexible diaphragm (62) is normally disposed across the pressure control chamber which functions as a check valve to control communication between the secondary regulator stage and the pressure control chamber. A clamping piston (64) provided with a central passage (72) normally clamps the flexible diaphragm in place across the pressure control chamber. In the event of excess pressure buildup in the pressure control chamber, the piston unclamps the diaphragm which collapses into its central passage to permit the pressurized gas to escape through exhaust vents (46). A valve arrangement (145-153) precludes adjustment of the secondary regulator stage until the source pressure has either been removed or relieved. Another form of the apparatus of the invention comprises a gauge assembly (180) also embodying the collapsible diaphragm element (198), Fig. 4. <IMAGE>

Title: Pedal cycle lighting system
Inventor: FINCH ROBERT PAUL
IPC: B62J6/00
Filed: 1983-04-18
Abstract: In a pedal cycle lighting system, negative half waves from an alternator G are passed via a diode D1 to a battery B1 and a front lamp L1 and positive half waves are passed via a diode D3 to a battery B2 and a rear lamp L2. Alternator G is connected to diodes D1, D3 via the primary of a current transformer T1, the secondary of which is connected via diodes D2, D4 to the batteries B1, B2 and lamps L1, L2. Transformer T1 increases the current available from alternator G at the expense of output voltage. Switches S1, S2 allow lamps L1, L2 to be directly connected to the primary of transformer T1, the batteries B1, B2 then being charged only from the transformer secondary and a resistor R then being connected across the primary. Charging current to the batteries may be smoothed by mutually coupled choker (CH1), (CH2), (Fig. 3). Means may be provided to limit the battery charging current, and the voltage applied to the lamps may be regulated, e.g. by a transistor or Zener diodes (Fig. 5). Series or parallel-connected lamps may be provided additionally or alternatively to lamps L1, L2 and connected across the series connected batteries (Figs. 4, 5). Solar cells to assist in battery charging, flashing direction indicators, and a radio or a cassette player may also be included. <IMAGE>

Title: Composite closure
Inventor: LECINSKI FRANK H
IPC: A47J41/02
Filed: 1983-06-06
Abstract: In order to reduce the torque required in the removal of a closure and also to eliminate the lubricant customarily incorporated in the gasket material of the closure, a composite closure is employed which includes a ring member 20 and a closure panel 22, with the ring member being so constructed as to provide for limited relative axial movement between the closure panel and the ring member. Thus, when the closure is removed, the ring member is initially rotated relative to the container and the closure panel, the seal between the gasket material 42 and the container neck finish 18 remaining unbroken. After an initial relative axial movement between the ring member and the closure panel detent means 52 or the ring member engages the closure panel and moves the same axially to break the seal with a minimal additional torque being required. <IMAGE>

Title: Electrical circuit assembly
Inventor: POLLACK JOEL MARTIN
IPC: H05K3/46
Filed: 1983-07-29
Abstract: Methods for forming high density conductive circuit patterns and electrical interconnections thereto. A pattern of conductors 18a, 18b, or bus-bars, is initially fabricated by electroplating or electroforming utilizing photoresist pattern delineation. Next, the conductors are overcoated with a thin insulating photosensitive film (11). Thereafter, a two-dimensional array of lead-width vias (12) are formed in the photosensitive film to expose the underlying conductors. The vias are spaced one from another in a predetermined matrix array so that the spacing between adjacent vias is greater than the spacing between adjacent conductors in the underlying circuit. Next, a conductive material (15) is electroplated through the vias and over the photosensitive layer to form comparatively large mushroom-shaped interconnect bumps. For added strength, the bumps and associated structure may be coated with a layer (17) of epoxy which, after curing, is abraded to expose a two-dimensional array of flat bonding pads (19). <IMAGE>

Patent GB-2137913-A (GB)
Title: Electrical connectors
Inventor: LARSSON PETER LARS
IPC: H01R4/02
Filed: 1984-04-11
Abstract: Connectors for terminating and splicing high voltage power cables comprise a metallic tubular sleeve having an open end for receiving an electrical conductor and a closed end. The inner wall of the sleeve is pretinned. The sleeve can be provided with a slug of solder proximate to the closed end. A connection is made by inserting the conductor into the sleeve, heating the solder, and as the solder melts, relatively moving the connector and the conductor toward each. The connector can be provided with an insert to accommodate conductors that are non-circular in cross-section. The connector can be provided with means for pressuring the slug of solder toward the open end of the sleeve at the temperature at which the slug of solder melts. With this connector, no relative movement between the conductor and the connector is required. Merely by melting the solder, the means for pressuring causes the solder to extrude around the conductor.

Title: Compatible transcodeable and hierarchial digital TV system
Inventor: POWERS KERNS HARRINGTON
IPC: H04N7/00
Filed: 1984-09-05
Abstract: New sampling criteria which are advantageous for a hierarchial digital TV system and can lead to compatibility with standard systems and to simplified transcoding between them use a number of samples per active line which is rich in powers of 2 to support several levels of hierarchy, with the number of such samples being advantageously selected as a multiplicative product of two integers one of which is a plural integer power of 2 (prefer 16) and the other of which has a value near 44. This can facilitate transcoding by enabling the samples to be processed in conveniently sized blocks. A number which satisfies these criteria is 704, which also approximates the number of samples yielded in the active line portion when sampling at 13.5 MHz in a 625/50 or 525/60 system, which number of samples may be approximated to 17/16x704 and 21/16x704 respectively. <IMAGE>

Title: Cooling extrusion coated optical cables
Inventor: VYAS MAHESH KUMAR RAMNIKLAL
IPC: B29C48/15
Filed: 1984-12-01
Abstract: In the manufacture of optical fibre cable a secondary coating such as a Nylon material is applied by extrusion to the optical fibre by pulling the fibre through an extruder crosshead (12) and along a cooling air path. Obtaining adequate cooling while providing for a reasonable production rate is difficult without needing an excessively long air path. In the present arrangement the above desiderata are achieved by passing the coated fibre through three cooling rings (13, 15, 16) spaced along the fibre's air path. The second ring is further from the first ring than the first ring is from the crosshead, and the third ring is further from the second ring than the second ring is from the first ring. Each cooling ring preferably has a bore of Venturi form, to enhance the air cooling effect. <IMAGE>
