Title: Sectional metal door or window frame - has U-section posts and traverse joined by tenons engaging traverse slots
IPC: E06B3/988
Filed: 1973-11-14
Abstract: A portal frame comprises three site connected elements, i.e. twin posts (10) and an overhead cross beam (11), all of U-cross section and joined by separate top plate tenons (20) which engage slots (26) in the cross beam. Plane tenons align vertically normal to the major door plane and slide into open topped envelopes (16) provided at the post tops. The envelopes are on the top and bottom of each post so the posts are interchangeable. The U-section fits over wall ends in the door opening, being fixed by nails or screws through the leg walls (13). Clip-on shallow inverted U section members with mitred slidably adjustable angles are utilised to mask nail heads.

Title: Bakers dough sticks adjustably spaced on carrier - for space saving during fermentation and automatic respacing before baking
IPC: A21B3/07
Filed: 1974-03-19
Abstract: An assembly for handling bakers dough 'sticks' for long, french loaves during both fermentation and oven-loading via band conveyor. Comprises a flexible sheet having an unfolded width equal to that of the loading conveyor but occupying much less width when corrugated longitudinally to conform to parallel channels in a rigid support plate; dough sticks are loaded into the corrugations, which are as close as possible, and remain there during the fermentation stage. After fermentation, the sheet is lifted clear of the support plate and transferred, complete with its load of fermented dough sticks, to be superimposed as an overlay on the loading conveyor band; the sheet is pulled out to its full width, thus spacing the sticks, and then secured by at least two of its edges to the conveyor band, using detachable fastenings for this purpose.

Title: Retraction and locking device - belt is vehicle safety belt looped by weight; centrifugally locked by deceleration
IPC: B60R22/34
Filed: 1974-04-12
Abstract: A vehicle safety belt stows away automatically when not in use and when worn, any abrupt change of speed or direction causes the belt to lock firmly. One end of the belt (3) is fixed to an anchor point (4) on the upper door pillar. A weight (8) suspended in a loop (9) of the belt pulls this down to effect retraction. A long strap (11) also runs in the loop.

Title: Vehicle anti-theft protection circuit - audio alarm with multivibrator connected to relay coil
IPC: B60R25/104
Filed: 1974-06-19
Abstract: The alarm, for actuating an audio warning upon closure of a contact discontinuously for a predetermined period, uses an electromagnetic relay with a pair of contacts mounted in series with the audio source, and an electronic multivibrator circuit, with its output connected to one terminal of the relay coil. A push-button actuates the multivibrator circuit, via an electronic timing circuit, so that the relay contacts are periodically closed and opened for a preset period, to provide a series of audio warnings. The multivibrator circuit can use two transistors and its operating frequency is varied by an adjustable resistance. The timing circuit may also employ a switching transistor, adjusted by a further resistor.

Title: Narrow span foot bridge - consists of hollow U-shaped girder made of welded metal plates with lengthwise trough shaped reinforcing girder underneath
IPC: E01D2/00
Filed: 1975-11-18
Abstract: The hollow girder of flattened U-shaped cross-section is preferably cambered and formed of metal plates welded together. The bottom of the U forms the tread surface (1) and the sides of the U (2) form the balustrade and hand-rail (5). A central, lengthwise trough-shaped girder (3) reinforces the structure and is welded to the underneath of the tread surface (1), and imparts flexural strength to the floor. Crosswise welded metal flanges (4) protrude outwards, to impart rigidity to the U-shaped structure. The depth of the flanges (4) beneath the flooring equals that of the central trough-speed girder. The footbridge does not exceed three-and-a-half metres in width and forty metres in span. The side balustrades are between 0.80 and 1.0 m in height.

Title: Time delay for drum and hose irrigation system - has counter to record strokes of drum operating ram and engage drive pawl after set number
Inventor: TURION JEAN-CLAUDE
IPC: A01G25/09
Filed: 1976-02-20
Abstract: The time delay prevents the rotation of a drum carrying an irrigation hose. This pays out the hose using a drive arm (9) engaging teeth in a ring gear (11). The arm moves on the same pivot as the drum (3) and is operated by an hydraulic ram (8). The arm carries a counter (17) preset to trigger a lever (20, 21) after a specified number of strokes, recorded by a contact (18). The drive pawl (10) is retained out of engagement with a ring gear by a rod (22) latching onto the lever. When the counter triggers the lever, the pawl pivots (16) downwards to commence rotating the drum.

Title: Refrigerator door sealing and holding strip - incorporates valve for exhaustion of air under pressure, to create suction
IPC: F25D23/08
Filed: 1976-03-18
Abstract: A resilient sealing strip for the door of a refrigerator or other piece of equipment consists of a U section strip (1) with a hole through it at one point, into which is sealed a spring loaded valve (5). When the door is shut, the flexible lips (43) are deformed against the frame forming a seal. At the same time, the space between them is compressed, and the air is forced out of the region, through the valve. A suction is thus created, which holds the door shut. To open the door again more easily, a handle can be incorporated to open the valve so as to release the vacuum.

Title: Continuous monitoring of vapour in air - involves using electron capture detector followed by universal detector and logic circuits
IPC: G01N27/64
Filed: 1976-06-24
Abstract: The method described is appliable to the continuous monitoring of a specific vapour, having a given electron capture coefficient, in a sample of air. A semi-permeable membrane is used to separate the vapour from the air. The vapour is then mixed with a carrier gas, either argon or helium, and it is passed into an electron capture detector and a universal detector. The electrical signals produced by these detectors are amplified separately and compared with threshhold levels. In this way binary signals are produced with arc applied to a logic circuit. The universal detector may be an argon ion detector, a helium ion detector, a hyper-frequency plasma emission detector, thermal conductivity detector, a photoionisation detector, etc..

Title: Light, flexible unlined coats - produced by trimming seams to the minimum and folding narrow bands of stiffening into the oversewn rim of the vertical facing
IPC: A41D27/24
Filed: 1976-10-19
Abstract: Mfr. of unlined coats of a light and supple construction is effected in two ways. First, where two fabrics are to be joined by seaming, the edge of the first fabric is over-seqn, and the second fabric is sewn flat on to it. The edge of the second fabric is trimmed by cutting flush tothe seam. The second fabric is then turned, and a second seam is effected by the side of, or on, the oversewn edge. Second, on the vertical facing of the garment, a narrow band of stiffening is folded into the oversewn hem. Two parallel lines of stitching are introduced, one near to the fold of the hem, and the other near to the oversewn edge. In the absence of a lining, the coat must to offer a finished appearance. To maintain a light and supple construction, seams are trimmed to the min. and vertical facings, which by known techniques can contain as many as five thicknesses of cloth, are restricted to a stiffened, oversewn hem, thus avoiding ugly, bulky extra thickness.
