Title: A device for wrapping sweets
IPC: B65B11/28
Filed: 1980-11-27
Abstract: The invention relates to a device for wrapping sweets which makes use of tongs-like holding elements and is provided with a cam disc controlling the opening and closing movements thereof and a means for the temporary delay of the rotary movement of each holding element, which delay does not effect the rotation of the conveyor wheels. It is the object of the invention to bring about, in a continuously driven device, the take-over of the sweets by the holding elements of a conveyor wheel at a relative rest along with an equalisation of varying rotational speeds. According to the invention, this is brought about in that the holding elements 5 are each mounted in a swivel body 12 which is secured to a bearing sleeve 13 in the conveyor wheel 2, which sleeve is provided with a roller lever 15 and bears, with this lever, against a cam disc 17 and in the interior of which there is mounted an adjusting shaft 18 which is connected to the holding elements 5 and which comprises a roller lever 21 which is connected to a cam disc 23 to control the operation of the elements 5. The body 12 is pivoted relative to the wheel by the interaction of the disc and lever 15. <IMAGE>

Patent GB-2086863-A (GB)
Title: Improvements relating to caps for containers
IPC: B65D41/44
Filed: 1981-09-30
Abstract: A tear-off metal cap for a bottle has a top with a depressed central area 11, and a peripheral skirt 12 which has an extension part forming a tab 13. A channel 15 on the underside of the cap between the central area 11 and the skirt 12 contains a sealing gasket. Two score lines 17 extend upward from the bottom edge of the skirt at opposite sides of the tab, and two further score lines 18 extend upward from the bottom edge of the skirt at positions diametrically opposite each other and symmetrically disposed with respect to the tab. When the tab is pulled upward the metal tears along score lines 17 and terminates in channel 15, breaking the seal and relieving any internal pressure in the bottle, whereafter the skirt tears at the location of score lines 18, enabling the cap to be removed completely. The score lines 17 are so positioned that an imaginary line joining the locations in the channel where tearing terminates extends tangentially or chordwise of the central area 11. Score lines 17 are for this purpose spaced apart by an angle in the range 80 DEG to 110 DEG . <IMAGE>

Title: A Flying Spot Scanner
IPC: G02B26/12
Filed: 1981-10-12
Abstract: A flying spot scanner, used for example to expose a photo-sensitive surface 10 to an intensity modulated beam of light to build up an image thereon, includes means (11) to enable a part of the scanning beam from head (8) to scan along a grating (14) with rulings oblique to the scanning direction, and thereafter fall on a photodetector, whereby the phase of the photodetector signal is indicative of deviations of the scanning spot position in a direction transverse to the intended scan line. By phase comparison of the signal with a signal representative of the spot position along the scanning direction, provided by a grating 13 with rulings normal to the scan line at a second photodetector, an error signal may be provided for controlling a mirror 5 to remove such deviations. In an alternative, grating 13 is ruled obliquely to the scan line in an opposite sense to grating 14. Deviations of sea speed are detected by monitoring the frequencies of the photodetector outputs. As shown, laser 1 and modulator 2 provide a recording beam, and laser 4, distinguishable by colour or polarisation, provides a beam for measurement. <IMAGE>

IPC: B01D61/06
Filed: 1982-07-09
Abstract: A plunger (31) is reciprocably driven, its movement to the right taking in brine from an inlet (48). On movement to the left, brine is forced through a bore (49) and a conduit 11 past a separation membrane (12). Clean water passes the membrane to an outlet (14). Concentrated brine under pressure enters a chamber (22) via passage (15) and acts on a second plunger (33), mechanically connected with the first plunger (31), to assist the first plunger in its movement to the left. On reverse movement, a valve 41 is operated to open an outlet (47) from which the concentrated brine is exhausted. A reciprocation drive is attached to a collar (40) for actuating the plungers and the valve. <IMAGE>
