Filed: 1969-10-16
Abstract: 1277969 Road traffic signals on vehicles ESSEX INTERNATIONAL Inc 16 Oct 1969 [28 Oct 1968] 50980/69 Heading G4Q The intensity of vehicle direction signalling lamps and stop lamps is reduced, for example at night, by including resistances in the signalling light circuits, the resistances becoming operative when the head lights or parking and tail lights are switched on. As shown in Fig. 1, switch 8 operates parking and head lights, switch 29 operates flashing light direction indicators, switch 28 is operated by application of the brake to light stop lamps, and switch 41 operates hazard warning flashing lights. Resistances R1, R2, and R3 are brought into the circuits on operation of the switch 8, terminals 14, 15, and 17 being disconnected and shunt relay 52 opening. The resistance of the resistors may increase with rise in temperature so as to provide an initial high light intensity. Fuses or circuit breakers 9, 12 act as overload protectors. Variable load flashers 40, 51 provide a uniform flashing rate. An additional resistor R4 (Fig. 4, not shown), may be included to maintain the prescribed rate of operation of a flasher not of the variable load type.

Abstract: 1,154,045. Suction cleaners. ELECTROLUX Ltd. 25 Nov., 1966 [26 Oct., 1966], No. 52802/66. Heading A4F. In a suction cleaner of the type having an elongated handle 9 pivoted to a casing 1 movable over the surface to be cleaned, means is provided for resisting downward manual movement of the handle over a given arc, the resistance being sufficient to cause lifting of the front end of the casing 1 but insufficient to prevent continuation of the downward manual movement through and beyond the arc. The pivotal connection of the handle 9 to the casing 1 includes a tubular T-piece 8 secured to the handle 9 and pivotable about an axis A in bearing members 8B (Fig. 2, not shown) fixed to the casing 1. Mounted on a rotatable shaft 5, carried by the casing 1, is a nose 12 urged by a spring 6 (not shown) into engagement with a stop 10 on the member 8 to hold the handle 9 in an upright position. The nose 12 may be retracted from the stop 10 by momentarily depressing a pedal 5c (not shown) to permit the handle 9 to be swung downwardly. The nose 12 is returned into engagement with a cam surface 11A on the member 8, and as the handle 9 is moved downwardly a steeper cam surface 11A engages the nose 12 and provides sufficient resistance to movement of the handle to cause the front end 1B of the casing 1 to be raised. If sufficient pressure is applied to the handle, the nose 12 rides over the cam surface 11B, and the handle 9 can be moved to a horizontal position.

Abstract: 1,152,615. Unwinding yarns from beams. FIBER INDUSTRIES Inc. 30 Nov., 1966 [9 Dec., 1965], No. 53538/66. Heading D1J. A beam having yarn wound thereon as a sheet made up of a large number of essentially parallel continuous multi-filament, zero twist, yarns spaced less than half an inch apart, has the yarns unwound in the form of said sheet and taken over a guide spaced from the beam before the yarns are separated from each other. Thus, in Fig. 2b, all the yarns leaving the beam first pass over a common bar 3 so that the yarns leave the beam in the form of a sheet. As illustrated the even yarns then pass over bars 4, 5 whilst the odd yarns leave via the bar 3, thus separating the yarns. The yarn may be of continuous filaments intermingled to give coherency to the yarn.

Abstract: 1410215 Sheet forming; blow moulding PLASTIC FORMING CO Inc 21 Nov 1972 [22 Nov 1971] 53729/72 Heading B5A Hollow thermoplastics articles are formed by placing a first heated sheet between a first mould part and a first face of an intermediate mould plate, placing a second heated sheet between a second mould part and a second face of the intermediate mould plate, closing the mould parts on to the mould plate member and conforming the sheets to their respective mould parts by a fluid pressure differential, opening the mould parts to disengage them from the mould plate and closing the mould parts together to join the formed sheets together. As shown in Fig. 1, sheets 1, 2 are placed, e.g. from an extruder, between a male mould part 3, plate member 5 and a female mould part 4. Male mould part 3 has a face 6 recessed at 8 to provide a rib 9 on the article in co-operation with projection 12 on plate 5, female mould part 4 having a cavity 7 with corners 10 facing face 11  of plate 5. Mould edges 13, 14 close on to parts 15 of plate 5 which are either heated or thermally insulated to retain these portions of the sheets at welding temperature. Air is blown through ducts (23, 24, Fig. 5, not shown) in plate 5 to effect forming, and if desired, vacuum may be applied via ducts (25). Adjustable spring- loaded clamping frames (17, 20) may be provided on members 3, 5 for clamping the sheets, which may be of different plastics, different thicknesses or different colours. A fixed needle (76) on part (3<SP>1</SP>) may also be used for blowmoulding and which forcibly punctures sheet (11) by means of collar (77) on plate (5<SP>1</SP>). An insert (28) may be loosely supported on plate (5<SP>1</SP>) for incorporation between the two sheets. In a preferred embodiment, Fig. 7, mould parts 3, 4 and plate 5 are mounted on carrier frame 30 for movement on rails 32 by cylinder 33. Mould part 4 is pinned to rods 37<SP>1</SP>, 39, 39<SP>1</SP> for movement therewith and mould part 3 is slidable on rods 37<SP>1</SP>, 39, 39<SP>1</SP> being opened and closed by cylinder 56 through toggle linkages 60, 61 fixed respectively to platen 68 which is pinned to rods 37<SP>1</SP>, 39, 39<SP>1</SP> and sliding platen 54 carrying mould part 3. Rod 39<SP>1</SP> is interrupted to allow swinging of plate 5 about rod 37<SP>1</SP> by cylinder (43, Fig. 8, not shown). An alternately interposable lost-motion mechanism (72, Figs. 13, 14, not shown) allows mould parts 3, 4 to close first against plate 5 and then against each other.
