The replacement reels 3a-3i, Fig. 2, may be located on a fixed drum (201), Fig. 5 (not shown), provided on the shaft 4, and between fingers (209) which can be moved axially of the drum and are retractable into the drum in such a way as to move the reels axially of shaft 4. The corresponding leading ends 1a-1i of the webs 2a-2i on the reels are held by suction through perforations 11 on a fixed drum 7 and are moved in synchronism with the reels by a reciprocable slide 5 towards a suction drum accelerating means 9. When a feeler (119), Fig. 1 (not shown), detects the near expiry of a web 101 from the expiring reel (102), the suction drum 9 is rotated to bring the web 2a, Fig. 8, held thereon to feed speed, a roller 129, mounted on a reciprocable carriage 121, is lowered and the carriage moves leftwards as viewed in Fig. 8, causing a rack 123 and pinion 127 device to rotate a knife 117 and cut the web 2a on the suction drum 9. Subsequently roller 132 drops off a carriage cam 131 and causes a knurling roller 112 to press expiring web 101 against the cut leading edge of web 2a to knurl them together, knife 115, having then rotated further, cutting off the expiring web 101. The carriage then returns and the roller 129 and knife 115 are moved laterally from the path of web 2a to allow the new reel 3a to be moved to the position originally occupied by reel (102) and the web 2a to move to the original position of web 101. The remaining replacement reels 3b-3i are then moved one increment as are their corresponding leading ends 1b-1i. Two knives may be provided.

Abstract: 1,190,503. Electric alarm clocks. GENERAL TIME CORP. April 26, 1968 [April 28, 1967; Dec. 18, 1967], No.19989/68. Heading G3T. An alarm system for an electric clock driven .by a synchronous motor 10 Fig. 1 (not shown) comprises a resilient vibrating element 24 carrying a striker 30 for striking a bell 31 or other sounding element, a permanent magnet 32 mounted on the element 24 adjacent an auxiliary pole 25 included in the synchronous motor 10 for generating alternating magnetic flux of a predetermined frequency to apply driving impulses to the element 24 via the magnet 32 at the same frequency as that of the alternating magnetic flux. The alarm is preset for actuation at a desired time by turning a control shaft 16 to adjust a gear wheel 14 relative to a gear wheel 15 driven by the driving train and having a slot 18 therein adapted to register at the pre-set time with a cam 12 on the gear wheel 14, whereby a control lever 19 may be rocked by a spring 22 to release the element 24 for vibration. The lever 19 is permitted so to release element 24 only if a manually adjustable plunger 20 is set so that slot 21 therein registers with a projection 21a and an arm 19b of the lever 19. If the natural frequency of vibration of the element 24 and its associated magnet 26 and striker 30 is a submultiple of the frequency of the driving impulses the striker 30 may be arranged to strike the bell 31 at a frequency equal to said natural frequency. An alternative embodiment is described in which the vibrating element is pivotally mounted between its ends.

Title: Storage device for electrical signals
IPC: H04N7/087
Filed: 1971-04-19
Abstract: 1307652 Multiplex pulse signalling; active delays INTERNATIONAL STANDARD ELECTRIC CORP 19 April 1971 [29 Jan 1970] 20167/71 Headings H3U and H4L The invention relates to a storage device which may be used in the television transmission system disclosed in Specification 1,306,467 wherein an audio signal occurring during a frame period is stored in the form of signal samples and transmitted as a time compressed signal during the frame flyback period. As shown in Fig. 1, the storage device has storage capacitors 1 to 6 which may be connected to an input signal source 59 or an output 60 by a changeover switch 19. The capacitors are connected in series with switches 7 to 12 respectively and these switches are operated sequentially by a ring counter 20 comprising elements 13 to 18. The switch 19 is operated in synchronism with a switch 22 under the control of circuit 25 controlled by line and frame sync. signals applied to terminals 26, 27 respectively. At the transmitter, with switches 19, 22 in the position shown, the input signal is fed to line 61 and the ring counter is operated at line frequency F T  so that signal samples are stored in the capacitors 1 to 6 during successive line periods in a frame period. At the end of a frame period circuit 25 changes over switches 19, 22 and the ring counter is operated at a much higher frequency, F T  so that the capacitors 1 to 6 are discharged successively during respective line periods in the frame flyback period. At the receiver this sequence is reversed. In a ring counter, Fig. 2. (not shown), each element 13 &c. comprises a pair of opposite type transistors, adjacent elements being operated by oppositely phased clock pulses. Alternatively, Fig. 4 not shown, IGFET transistors may be used, i.e. MOS semiconductor devices which are symmetrical.
Patent GB-480677-A (GB)
Title: Improvements in or relating to the polymerisation of drying oils
Filed: 1936-07-22
Abstract: In a process for polymerizing drying-oils by heating the initial oil in the presence of sulphur dioxide, such a large surface area of contact between the liquid and the gaseous phases and/or such a high concentration of sulphur dioxide in the liquid phase is employed that the rate of polymerization, as indicated by the rate of increase in viscosity, is substantially greater than that obtained when using hydrogen sulphide, nitrogen, hydrogen or carbon dioxide under the same conditions.  The large surface area of contact between the liquid and the gaseous phases may be obtained by bubbling the gas through the oil by means of a dispensing nozzle or other device adapted to subdivide the gas finely, and/or by stirring or agitating the oil while passing the gas through it.  The high concentration of the gas in the liquid phase may be obtained by heating the oil in the presence of sulphur dioxide under pressure.  The sulphur dioxide is preferably dry, and excess gas is removed from the product by blowing with an inert gas or by heating in vacuo.  In examples: (1) sulphur dioxide is passed through heated linseed oil, soya bean oil or Japanese sardine oil, while stirring; (2) sulphur dioxide is passed through a circular pipe pierced with fine holes into a heated body of linseed oil, and (3) a vessel one-fourth filled with linseed oil and three-fourths filled with sulphur dioxide at atmospheric pressure is closed and heated until the pressure of the gas is approximately doubled, whereby the concentration of the sulphur dioxide in the liquid phase is substantially increased. Specification 343,099 is referred to.

Abstract: 499,043. Tumbler switches. TUCKER & CO., Ltd., J. H., and FUKE, F. C. July 24, 1937, No. 20509. [Class 38 (v)] A tumbler switch for alternating current circuits comprises an insulating block b pivoted on a projection a<1> on the base and having an adjustable stop a<4> for limiting the pivotal movement. The member b carries a contact b<2> which co-operates with a fixed contact a<2> and which is connected to a contact a<5> cooperating with a contact b<5> carried on a spring blade b<6> fixed to the member b at b<8>. A flexible conductor b<9> connects contact b<5> to an angle piece a<7> and serves to hold the member b in position as well as to form a connection to a terminal not shown. In the position shown, current passes from member a<7> through conductor b9, contacts b<5>, a<5>, b2 and a2 to a terminal not shown. On moving tumbler c until roller c<1> passes fulcrum a<1> member b tilts and contact is broken with a small gap between contacts a<2>, b<2>. Further movement of the tumbler results in contacts a<5>, b<5> separating to give a second larger break in series. In the modification shown in Fig. 7, an insulating block f is suspended from the bridge (not shown) by parallel links g and is moved to right and left by a dolly and dead-centre spring link (not shown). The block f has pivoted to it at f <4> pair of contact arms f for engagement with two pairs of fixed contacts d<1>, d<2>, the arrangement being such that when block f moves to the left, the ends f<2> of the contact arms first engage contacts d<1>. The arms f<1> then tilt about f<4> and cause engagement of ends f<3> with contacts d<2>. When moving in the opening direction contact is first broken at f<3>, d2 and then a larger isolating gap is introduced at f<2>, d<1>. In a further modification, the contacts are arranged on the underside of the block f.
