Title: Improvements in or relating to can sealing machines
IPC: B67B3/24
Filed: 1932-01-30
Abstract: 388,190. Sealing cans in vacuo. SMITH, P. S. D., 7, King's Bench Walk, Temple, London.-(General Can Co. ; 16th Street, Chicago, U.S.A.) Jan. 30, 1932, No. 2890. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 1, 1932.] [Class 125 (ii).] In a machine for evacuating and sealing cans of foodstuffs &c., the filled can with a cover 24 loosely in position is placed on a table 14 and a hood 21 is caused to descend and make a tight joint with a base 12 which yields against springs 13. A cam on the crank mechanism which actuates the hood 21 then opens a valve in a pipe 19, through which the chamber formed by the hood and base is evacuated, the air passing through radial grooves 14a in the table 14. During the operation a spring- pressed plunger 48 projects downwardly to hold the can lid 24 against accidental displacement whilst the air is escaping from the can. Further descent of the hood brings into operation a head 25 which presses the lid 24 into its closing position. The hood 21 has a pin-and-slot connection 52, 53 with a shaft 36 and when this shaft is arrested by a nut 46 striking a cross-bar 45, inclines 37 at its lower end force outwardly, against springs 34, a number of radial plungers 29, Figs. 2 and 3, mounted in the head 25, these plungers forming lugs 39 in the vertical wall of the can lid 24 to assist in securing it in position.

Abstract: 372,352. Dynamo-electric machines. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Feb. 3, 1931, No. 3451. Convention date, Feb. 21, 1930. [Class 35.] Exciting; alternating current induction machines. -A synchronous or an asynchronous machine 1 supplying wattless current is started as an asynchronous motor by connecting a choking coil 4 in series with the stator winding 3 and a fixed resistance 6 in the rotor circuit, and connecting the rotor to a source of continuous current or to a mechanically-coupled commutatorexciting machine 2, the choking coil being subsequently cut out. The choking coil may be constructed as a transformer in which the secondary can be short-circuited by steps and then cut out if necessary. The switches 8, 9 for cutting out the choke and switching in the rotor excitation respectively are preferably interlocked so that the choke cannot be cut out until after the switching in of the excitation. The interlocking mechanism may also be connected with a device influenced by the wattless current in the stator circuit so that the choke cannot be switched off until the wattless current has fallen below a predetermined value.

Title: Improvements in or relating to resinous compositions
IPC: C08G8/00
Filed: 1942-03-17
Abstract: 556,126. Resinous condensation products. BAKELITE, Ltd. March 17, 1942, No. 3543. Convention date, March 20, 1941. [Class 2 (iii)] Hydrous metal oxides in gelatinous form are incorporated in a. phenol-aldehyde resinous reaction mixture prior to dehydration and the mixture is then dehydrated. The resin may be of either the heat-hardening or potentially reactive type. Suitable oxides are those of aluminium, cerium, thorium, titanium, tungsten, lead, bismuth, cadmium, copper, antimony, nickel, zirconium, iron, chromium, arsenic, manganese, silicon, tin, vanadium, praseodymium, neodymium, platinum and iridium. In examples (1) phenol, aqueous formaldehyde' and phosphoric acid are refluxed for four or five hours after which a gelatinous hydrous oxide of chromium is stirred in and the mixture is dehydrated by heating at atmospheric pressure with continuous stirring. By treating the pulverized fusible resinous mass with a hardener, e.g. hexamethylenetetramine, paraformaldehyde or trioxymethylene, it is converted on heating to an infusible product. (2) Phenol, aqueous formaldehyde and ammonia are refluxed for 80 minutes, a gelatinous hydrous oxide of chromium stirred in the mixture dehydrated under vacuum. The product may be mixed on heated rolls with wood flour, cotton flock, asbestos, pigments and dyes to form a moulding composition. It may be dissolved in alcohol to form a heat-hardening varnish for impregnating paper or fibre sheets in making laminated products. The composition may' also be used as a bonding agent for abrasive grit in the manufacture of grinding wheels. Specifications 28155/10, 148,264 and 248,726, [all in Class 2 (iii)], are referred to.

Title: Improvements in and relating to automatic weighing machines
IPC: G01G13/00
Filed: 1935-02-04
Abstract: 434,394. Automatic-feed weighers. GIBSON, A. B., 20, Sykes Avenue, Weston, Ontario, Canada. Feb. 4, 1935, No. 3565. [Class 143] In an automatic weighing-machine the material is fed to the weigh bucket through a throat member containing a rotating valve movable longitudinally to regulate the flow, and means are provided for automatically controlling the longitudinal position of the valve in relation to the throat during the weighing operation. Assuming the desired charge has entered the weigh bucket 7, the weighbeam 8 rocks and closes an electric contact 53 causing an electromagnet 57 to liberate a spring-pressed closure member 42 and cut off the feed. The closing movement completes a circuit through an electromagnet 58 thereby coupling up a clutch to impart a single revolution to a cam shaft, the cams on which actuate (1) a lever 50 to open and close the discharge gates 21 of the weigh bucket ; (2) a lever 27, rod 29 and lever 33 to raise a constantly rotating shaft 4 to its highest position with its agitator valve 5 clear of the feed throat 2 ; (3) a lever 54 to lock the weighbeam temporarily by means of a clamping screw 55 during the subsequent dumping of material into the weigh bucket; and (4) a lever 44 to open the closure member 42 and re-set it on its catch. On the opening of the closure member the material accumulated in a measuring chamber 3 is dumped into the weigh bucket, the weight being then made up by a constantly decreasing stream through the throat 2 as the rotating and descending agitator valve 5 restricts the flow to a minimum. On completion of the charge the closure member 42 cuts off the feed as described above. The volume of the measuring chamber 3 may be regulated by raising or lowering the superposed conduit 1.

Abstract: 855,228. Knitting-machines. WOLSEY Ltd. March 7, 1957 [Feb. 6, 1956], No. 3581/56. Class 74 (2). Whenever a yarn change occurs, the length of yarn extending between the ingoing feeder 12 and its trapper 11 is engaged by the notched end of an endwise slidable strip 14 and positively deflected into the needle circle, the length of yarn so deflected being thus constant irrespective of the number of trappers arranged in line, or of which one of the trappers is holding the yarn. At each yarn change, the strip 14 is advanced, against the action of a spring 28, by one of projections 34 carried on a rotary cam disc 33 and operating through a bell-crank lever 36, 37 and Bowden cable 30. The cam disc is actuated by a pawl which also actuates the main control means of the yarn change mechanism. The strip 14, when moved in towards the needle circle, may also engage the length of yarn extending from the needles to the feeder being withdrawn, to facilitate its engagement by its trapper and to guide the severed yarn end closer to the needle circle. Specifications 301,350 and 301,360 are referred to.

Marks x, y are provided on the pattern roller and bridle for exact adjustment of adjoining or subsequent patterns. More than one set of rollers may be mounted in the apparatus, as shown in Fig. 1, whereby, by the use of different colours, polychrome effects may be obtained.
