Title: Improvements in and relating to thread control means for sewing machines
IPC: D05B27/18
Filed: 1941-05-12
Abstract: 545,237. Sewing machines. UNION SPECIAL. MACHINE CO. May 12, 1941, No. 6105. Convention date, July 30, 1940. [Class 112] In a sewing machine using a plurality of threads, the threads, between the usual tensioning devices and the stitching instrumentalities, are taken round individual grooves in a single feed-proportioning wheel whereby the feeds of the threads are proportioned to the diameters of the several grooves. In the example, the needle thread N passes through two tension devices 53, 22 in series and the two looper threads L, L' pass through the tension device 22 only. Thereafter the needle thread takes a turn round the small diameter groove 16 and the looper threads take a turn round the equal large diameter grooves 17, 18 before passing to the usual threadhandling devices on the machine. In this way a constant proportioning of the thread feeds is secured. The disposition of the stitch concatenations may be varied by varying the relative diameters of the grooves. This may be done by using a wheel built up of discs each having a single groove. The feed-proportioning wheel may be used in other textile machinery.

Title: Can opener
IPC: B67B7/70
Filed: 1961-02-20
Abstract: 947,192. Can openers. SUNBEAM CORPORATION. Feb. 20, 1961 [June 30, 1960], No. 6218/61. Heading B8D. A can opener comprises an opening mechanism 54, 58 mounted in a frame 34 and a lid holding arm 148 pivoted to the frame 34 at 158 and carrying a magnet 150 in a position either to attract the lid of a can being opened or to hold the arm 148 in contact with the frame 34 (Fig. 4), the arm 148 being biased to the lid attracting position. The can opening mechanism comprises a serrated feed wheel 54, driven by an electric motor through a worm and nylon gears 98, 126, and a cutter wheel 58 freely pivoted on an operating lever 62. The lever 62 is pivoted in a block 70 which is displaceable vertically against spring 74; the shaft 56 is displaceable axially to allow for various sizes of cans. In operation, the arm 148 is released from contact with the frame, the lever 62 is pivoted away in an anticlockwise direction so that the cutter 58 is lifted clear of the feed wheel 54 and a can is inserted so that its lip engages the edge of the feedwheel 54. The lever 62 is then moved back and pressed firmly down so that the cutter engages the edge of the can lid. As it is pressed down lever 62 causes a microswitch 136 to start the motor; the can is rotated and the cutter 58 cuts around the lid. As the lid becomes separated from the can it is attracted by the magnet 150 and lifted clear of the can. The lever 62 is then lifted and the open can removed, the lid being subsequently removed from the magnet 150 and the arm 148 being pushed down to engage the frame to cover and protect the feed wheel 54. The can opener may be mounted directly on to a recessed electric wall socket 48 or alternatively on to a separate stand (Fig. 1, not shown). Specification 663,292 is referred to.

Title: Alarm system
IPC: G08B25/00
Filed: 1975-02-13
Abstract: 1472035 Alarm systems INSTITUTET FOR INNOVATIONSTEKNIK AB 13 Feb 1975 [13 Feb 1974] 6218/75 Heading G4H An alarm is signalled using a portable primary transmitter which transmits a standby code and an alarm code to a receiver which on receiving the standby code is put into a state to receive the alarm code, responding to the alarm code by actuating an associated secondary transmitter to send an alarm signal to an alarm centre. As disclosed, each of a number of areas has a number of primary transmitters (using the same codes, which are different from those in other areas to prevent false alarms) which can send tone sequences constituting the codes by radio to an area receiver which actuates its associated secondary transmitter to send a tone sequence identifying the area by radio, telephone line or other line to the alarm centre for print out of the area identity. Each primary transmitter is in the form of a wrist watch, pen or cigarette lighter and has two buttons which must be pressed together, twice, to send the standby and alarm codes together, twice, the receiver decoding the first occurrence of the standby code to return an acknowledgement signal and initiate a timed period, e.g. 5-15 seconds. If the (second occurrence of the) alarm code is decoded within this period, the acknowledgement signal is changed and area identity is signalled to the alarm centre as stated. The use of two buttons twice, obviates accidental operation.

Title: A process for the production of gases comprising acetylene
IPC: C07C7/11
Filed: 1957-02-25
Abstract: <PICT:0858666/IV(b)/1> Gases comprising acetylene are produced by subjecting to pyrolysis in the liquid state at least one hydrocarbon containing at least 3 carbon atoms to produce a gas containing acetylene, washing the gas with at least one aliphatic hydrocarbon which contains at least 3 carbon atoms and is liquid under the conditions used to remove acetylene hydrocarbons containing at least 4 carbon atoms and a portion of the C3 acetylenes, returning the resulting solution to the pyrolysis and washing the gas resulting from the washing operation with a solvent in a second stage to remove hydrocarbons containing 3 carbon atoms still present in the gas. The gas is preferably washed at a temperature in the range of -20 DEG  to -40 DEG C. and at a pressure of 7-16 atmospheres, washing may also be effected in two stages.  The washing liquid may be pentane, hexane, octane, isooctane, diisobutylene, decane, dodecane, or propane, n-or iso-butane, isobutylene, or cyclic or aromatic hydrocarbons such as cyclohexane, toluene or xylene.  In an example, light benzine having a boiling range of 50-150 DEG  C. is pyrolysed to produce a crude gas containing 13,1 % by volume of acetylene which gas is passed from a gasometer 1 to a compressor 2 in which the pressure is raised to 10 atmospheres absolute.  It then passes to a washing column 3 in which acetylene hydrocarbons containing 4 carbon atoms are washed out with the light benzine. The residue of the less soluble hydrocarbons containing 3 carbon atoms, i.e. C3H4 and C3H6 is removed from the issuing gases at about -20 DEG C. in a second washing column 4 by means of a light benzine boiling at about 100 DEG C.  The washing liquid is then expanded to a pressure of 1,4 atmospheres absolute and passed into a degassing column 5 in which the C3 gases are expelled at 60-70 DEG C. the regenerated washing liquid being reintroduced into the washing column 4 through a conduit 8.  The gaseous mixture is returned to the gasometer 1.

Abstract: 195,946. Soc. Anon. A. Saurer. April 8, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Jacquards; dobbies.-In apparatus for shedding controlled by jacquards provision is made whereby the card can be reset during the movement of the healds. In Fig. 1, a card 6 acts through needle members 1, 2, a rocking member and a link to position a slide 3 carried by a vertically reciprocated carriage 9 actuated by a pin 8 engaging a groove cam 7. If the slide 3 is adjusted over either of the members 4, 5, which are guided in arms 14, 15 mounted at their low ends on fixed pivots, the descent of the carriage 9 with the slide 3 presses down one of the members 4, 5 to rock a lever 10 from which the healds are operated. On the upward movement of the carriage 9, another cam 13 on the cam shaft rocks the arms 14, 15 apart so that the members 4, 5 are clear of the slide 3 which can then be reset by card, whilst projections 16, 17 on the carriage return the members 4, 5 and brings the rock lever 10 back to its initial position, the cam 13 allowing the arms 14, 15 to move towards each other again into operative position. In Fig. 2, the card 6<1> acts on needle members 1<1>, 2<1> to set a rocker 3<1> mounted on a fixed pivot 22 and carrying pins engaging the forked arms of bell cranks 4<1>, 5<1> pivoted on arms 20, 21 movable on a concave pivot 23 and connected by links 24, 25 to two arms of a three-armed pivoted lever 26, the third arm of which engages a groove cam 27. The setting of the rocker 3 by the card positions the bell cranks so that the second arm of one is opposite a projection on the rock lever 10<1> for operating the healds, the second arm of the other bell crank being moved clear of a second projection. The rotating groove cam 27 now acting through the three-armed lever 26 and links 24, 25 rocks the arms 20, 21, and through the bellcrank 4<1> the rock lever 10<1>. The continued movement of the grooved cam effects the return of the lock lever 10<1> by one of the parts 32, 33, the bell-cranks 4<1>, 5<1> being free during this movement to permit of resetting of the rocker 3<1>, an arm 30 pivoted at 31 is operated by a second groove 28 on the cam to engage one or other side of a projection on the rocker and complete its movement after having been moved clear thereof to permit setting by the card. This device may be adapted to the arrangement shown in Fig. 1.
