Title: Distance pieces for sound insulating windows - has side channels abutting outer panels and carrying inner channels
IPC: C03C27/12
Filed: 1974-09-19
Abstract: Distance pieces for multiglazed sound insulating windows spaces the panes whilst permitting dehydration of the cavity. A preferred embodiment envisages four panes (31, 32, 33, 34) with three lateral interpane gaps of say 5mm, 50mm and 5mm: the window thus insulating thermally and acoustically. The spacer in section comprises a hollow member (45) with a perforated horizontal top wall (36) and incorporating two U sections (53), one positioned at each side of and flush with this top. Inner panes (33, 34) lodge in the U's and outer panes (31, 32) abut the external vertical U legs; external pairs of frames thus being separated by these legs. The core of the member houses dehydration media.

Title: Stopping system for ship - has flaps swung out from hull by actuators housed in chambers in hull
IPC: B63H25/44
Filed: 1974-11-29
Abstract: A stopping system for a vessel such as a cargo boat employs a flap (4) or flaps normally flush with the side of the hull under the water line. The flaps can be pivoted outwards about vertical hinges (5a) to produce a braking effect. When closed each flap forms a seal over a compartment (7) housing a hydraulic cylinder (6) which can push the flap open, or pull it shut when required. The cylinders (6) can be operated separately, and the flaps can be thus operated to have a steering effect. Flaps could be operated to open forwards against the flow of water past the hull, but this application is limited owing to the high stresses present.

Title: Static convertor for powered traction motor - operates electrically from DC or AC supplies
Inventor: CHAUPRADE ROBERT
IPC: H02M7/00
Filed: 1975-08-29
Abstract: Solid state static converter for electrically powered traction motors. The power source supplying the motor may be either A.C. or D.C. The circuitry is based on a parallel coupled chopper arrangement for D.C. sources and a controlled rectifier bridge for A.C. sources. Both bridge and chopper circuits use the same components, the mode conversionis achieved by a series of single pole switches. Two blocks, each consisting of three controlled rectifier elements with their associated capacities and inductances, are fed in parallel from supply terminals common to both A.C. and D.C. power sources. The change of operating mode is achieved by a total of seven individuals single pole switches and a pair of diodes, the motor itself being provided with a compensating network.

Title: Sand barrier application to oil wells - in one trip by valve seat shearing preceding oil flow resumption
IPC: E21B43/04
Filed: 1975-10-15
Abstract: Sand and gravel can be prevented from entering and clogging the flow string of a productive oil well by lowering a packer with a protruding flushing tube into the well. A carrier liquid with a sand barrier medium is pumped into the desired zone to the required height above a strainer. Hydraulic shearing of a valve seat then allows the resumption of the oil flow through the barrier medium and the strainer. This requires only one trip of the string with the packer to the bottom of the well, resulting in considerable time savings. The tools required are simple and reliable; they do not require very fine tolerances.

Patent FR-2303150-A1 (FR)
IPC: E06B9/80
Filed: 1976-02-27
Abstract: The means for protecting against intrusion has a locking member (20) mounted on the building side, the roller-blind bars (4) engaging movably in one another in the running direction of the roller blind such that, on subjecting the roller blind to tensile stress on that side of the blind directed towards the building, gaps appear between neighbouring roller-bars (4). In the event of unauthorised pushing-up of the roller blind, such a means for protecting against intrusion is intended to become effective automatically without having to transfer it into a locking position when letting the blind down or drawing it up. For this purpose there is provided, on the roller blind, at least one release member (30) which is connected to at least one roller-blind bar (4) such that, when closing the gaps (14) of the roller-blind bars (4), it can be moved away into a stop position, the locking member (20) being located in the movement path of the release member (30) in the stop position. As a result, the relative movement of the roller-blind bars (4), which are pushed together, closing the gaps (14), when pushed up out of their lowered position, is used to control or unlock the locking member (20). As a result, the locking member (20) is transferred into the locking position only when the roller blind is pushed up and not when it is drawn up. When the roller blind is pushed up, the release member (30) stops at the locking member (20), which prevents the roller blind from being pushed up further.

Title: Cleaning device for hydraulic intake gratings - has controllable rake mounted on mobile chassis raised by motor driven belts
IPC: E02B8/02
Filed: 1976-05-07
Abstract: The sliding chassis (4), with end blocks (8) provided with nylon skates, and is free to slide in the U-sectioned uprights of the grill. The chassis carries a rake (6) and a board (7) pivoted about a spindle (6). The chassis is allowed to fall under its own weight but is raised by belts (10) which are wound onto drums (11) by a motor (13). The rake is provided with a mechanism, powered by a motor which allows its angle with respect to the grill to be varied. When the chassis is falling the rake is held clear from the grill, then it is returned to its normal position between the grill bars so that the debris is scraped out when the chassis is raised.
