Title: Surge current suppressing adapter for an incandescent lamp
Inventor: MASAKI KAZUMI
IPC: H05B39/02
Filed: 1985-05-28
Abstract: The adapter has a series circuit of diodes D1, D2, D3 and a resistor R1 connected to the positive output of a bridge rectifier A, and an RC- integrating circuit R2, C2 connected in parallel to the series circuit. Either a thyristor SCR or an electromagnetic relay (Re) (Fig. 3) is arranged to short circuit resistor R1 when the voltage across the capacitor C2 of the integrating circuit reaches a predetermined level. The adapter is arranged to illuminate an incandescent lamp Z with a relatively high brightness, but also to significantly prolong the life of the lamp due to the absence of surge current. The adapter may be used to energise the lamp with a voltage of, for example, 1.3 times its rated voltage in order to obtain an increased luminous intensity. <IMAGE>

Title: A rapidly releasable hydrostatic coupling device for objects submerged in water
Inventor: LUNDBERG THORSTEN
IPC: E02D23/16
Filed: 1985-07-29
Abstract: The device comprises a seal (20) mounted in a groove (18) in a first object (12) e.g. an offshore platform which in use will be pressed against the other object (16) which rests on the sea bed e.g. a foundation a closed loop delimiting a space (23) facing the other object (16). The seal (20) is a membrane mounted along its sides, dividing the groove (18) into an outer part (21), open to the ambient water, and an inner part (22), which via a pipe (24, 28) can be connected to a reservoir (29) above the water surface, to establish a pressure higher than the ambient water pressure in the inner part, and so press the seal (20) against the foundation. Means (33) are also arranged for pumping out water from the space (23) delimited by the seal (20) and both objects, whereby the weight of water acting on the body (12) above the space (23) exists a set downward force to couple the two objects together. The coupling is released by admitting ambient water to space (23) via pipe (24). <IMAGE>

Title: A device for use in assessing the position of a body
Inventor: ALMANAR INDRA PUTRA
IPC: G01D5/26
Filed: 1985-08-06
Abstract: The device is in the form of a block in which are mounted two parallel quadrant detectors Q1, Q2 at right angles to a third detector Q3. Parallel light 32 from a laser 30 is split by beam splitter S1 into beam 35 going to Q1 and beam 36 going via retroreflector 37 to beam splitter S2 producing beam 39 going to Q3 and beam 38 going to Q2. Movement of the block relative to beam 32 produces signals from Q1, Q2, Q3 from which position errors can be calculated. Splitter S3 may send beam 34 to a second similar device. Three such devices can be used to provide position errors caused by movement in two orthogonal directions and by roll, pitch and yaw, relative to a datum. Errors in a third orthogonal direction are obtained using a laser interferometer. <IMAGE>

Title: Improvements relating to pumps
Inventor: PATRICK LLEWELLYN MORGAN
IPC: F04B1/28
Filed: 1985-08-14
Abstract: A pump comprises two upper pairs of pistons 5 symmetrically arranged at 90 DEG  with respect to the axis of the pump and two lower pairs of pistons 5 similarly arranged. The upper pairs of pistons are reciprocated by a rotary cam 2 whilst the lower pistons are reciprocated by a rotary cam 3, the cams being rotatable about a vertical axis. The profiles of the cams complement one another so that the combined output from one pair of upper pistons and one pair of lower pistons defines a substantially linear flow. The cam faces of the cams 2 and 3 are angled and act in a roller followers 14 on pivoting members 16, movement of which causes reciprocation of pillars 8 which act on bars 6 or 7 linked to respective pairs of pistons 5. The pillars 8 are mounted screwthreadedly on rods 13 so that, by rotation of the rods 13, the pillars can be displaced transversely of the axis to adjust the stroke length of the pistons 5 and thus the rate of output of the pump. <IMAGE>
Patent GB-2167033-A (GB)
Title: Foraminous belt conveyor
Inventor: HINZMANN ALFRED
IPC: A24C5/39
Filed: 1985-11-18
Abstract: A foraminous endless bet (17) is trained over a set of pulleys so that it forms a first reach and a second reach which is twisted through 180 degrees. One side of the first reach is adjacent to a suction chamber (16) and the other side of the first reach attracts particles of tobacco which form a growing tobacco stream. The 180-degree twist of the second reach enables the belt to relieve itself of minute solid particles which adhere to the other side of its first reach because the other side of the first reach becomes the one side of such reach during next travel along the stream building zone and so forth. Moreover, the twist contributes to more uniform wear upon the belt and imparts to the belt superior pulley-tracking properties. <IMAGE>
