Title: Improvements in or relating to a machine for feeding sheets
IPC: B41F21/05
Filed: 1948-02-09
Abstract: 643,542. Feeding sheets. HARRIS-SEYBOLD CO. Feb. 9, 1948, No. 3711. Convention date, July 27, 1944. [Class 100 (i)] Sheets are fed to printing and like machines in an overlapping stream and are conveyed to the grippers 59 of an impression cylinder 18 by a gripper cylinder 17 fitted with means for withdrawing the leading sheet from the feed table 10 at an accelerated speed so as to clear this sheet from an underneath one before the latter reaches the front stops 9. The registered sheet is taken from the front stops 9 by grippers 15 on an intermittently rotated arm 14 held stationary by a catch on a cam-operated arm 27 which releases the arm prior to its acceleration by engagement of an arm 35 integral with the arm 14 with a roller 33 on an arm 34 fixed to the carrier cylinder 17 which is fitted with grippers 16 for carrying the sheets to the grippers 59. A gear 20 on cylinder 17 then engages a segmental gear 24 and the sheet is accelerated to the speed of the grippers 16 and transferred thereto. As the sheet is being advanced counterclockwise by the cylinder 17 a roller 44 on a rotating arm 43 carried by the cylinder 17 and driven by gearing 50, 51, 55 is advanced by the arm 43 from a position inside a recess in the cylinder to the position shown in Fig. 5, thus causing the tail end of the sheet to be withdrawn quickly from the stops 9 to permit them to fall before the underneath sheet reaches the stops.

Title: Improvements in or relating to jacquard controlled knitting machines
IPC: D04B15/70
Filed: 1937-02-08
Abstract: 489,314. Knitting-machines. DUBIED & CIE SOC. ANON., E. Feb. 8, 1937, No. 3734. Convention date, Feb. 11, 1936. [Class 74 (ii)] In a Jacquard controlled parallel or straight bar knitting-machine in which the needles are selected by auxiliary pushers, each needle is controlled by at least two pushers which are selected by the Jacquard device for cooperation with an auxiliary slide lock and through the medium of an intermediary slide, actuate the needle or jack to cause it to co-operate with the needle slide lock ; by this means the needles are adapted to knit cardigan, long and short stitches. Each needle may be controlled by more than two pushers which co-operate with additional auxiliary locks, and for double and triple cam machines the pushers and auxiliary locks arp duplicated or triplicated. As shown in Fig. 1, the needle 2, having its heel 2<1> engaging the main needle slide lock 4, is connected to a jack 3 which engages the intermediary member 11 slidable in a yoked bed 12 integral with the needle bed 1. The auxiliary pushers 13-16 are guided by the member 11 and yoke of the bed 12 and are actuated by the Jacquard card 17 for co-operation with the cam portions of the auxiliary slide lock 18 by which the tips of the pushers advanced by the card are moved so that the member 11 is raised to move the jack 3. If two pushers 13, 14 are provided for each needle and are not advanced by the card 17, the jacks are not moved and the needles remain in alignment but if, e.g. the upper pushers 13 remain inactive and the lower pushers 14 are advanced by the card, the tips 14<1> thereof are engaged by the cam portion 23, Fig. 3, of the auxiliary lock and raised so that the jacks 3 are also raised; the tips 141 then slide on the cam portion 23 and the heels 3<1> of the jacks follow the contour of the cam portion 8 of the main lock, Fig. 4, up to the line V-V so that the needles are advanced halfway to form cardigan loops. The heels of the inoperative pushers 13 then engage the cam portion 20 of the auxiliary lock and are shifted downwards to depress the jacks and disengage the heels thereof from the cam portion 8 of the main lock while the needles are guided by the cam portions 6, 7 thereof. The pushers 14 are again raised by the cam portion 23 of the auxiliary lock, the jacks engaging the main lock and the needles being retained between the cam portions 6, 7 to the line X-X and retracted to the line XI-XI while the jacks are engaged by the cam portion 8 of the main lock until retracted by the cam portion 10, the needle heels entering the corresponding recess in the cam portion 5 so that long stitches are formed. Afterwards the needles are retracted and moved into alignment and the cam portion 21 of the auxiliary lock is shifted downwards to align the heels of the auxiliary pushers 13 not in the operative position and so depress the needle jacks while the cam 31 moves the pushers 14 back to their initial position. Other patterning possibilities are described.

Title: Improvements in or relating to the production of grey cast iron
IPC: C21C1/08
Filed: 1937-02-10
Abstract: An all-pearlitic structure (which may be partly or wholly sorbitic) with possible traces of cementite, but no free ferrite whatsoever is produced in grey iron castings made in preheated moulds of refractory material and containing materials which inhibit and promote the formation of ferrite, by altering one of the following factors: (a) the quantity of ferrite-promoting material (which must always be so high as normally to produce a ferritic casting); (b) the quantity of ferrite-inhibiting material, and (c) the rate of cooling as determined by the action of the casting and the temperature of the mould.  The ferrite-promoting material may be one or more of silicon, nickel, or copper in amount equivalent to 1,5-7 per cent of silicon, it being reckoned that 0,4 per bent of silicon is equivalent to 1 per cent of nickel and 0,35 per cent of silicon is equivalent to 1 per cent of copper, no more than 3,5 per cent of nickel and 4 per cent of copper being however present.  The ferrite-inhibiting material may be one or more of chromium, manganese, or molybdenum, in amount equal to 1-6 per cent, up to 3,5 per cent, and up to 1,5 per cent respectively, it being reckoned that 0,3 per cent of molybdenum is approximately equal to 0,2 per cent of chromium and 0,25 per cent of manganese (after the first 1,75 per cent of manganese, which is stated to be without effect) being equal to 0,15 per cent of chromium.  The inhibiting-material may be added to the cast in the pouring-ladle, the cast preferably containing a quantity of scrap from a previous operation.  Specifications 147,933, [Class 82 (i)], and 495,820 are referred to.  Reference has been directed by the Comptroller to Specification 245,196, [Class 82 (i)].

Filed: 1943-03-12
Abstract: 566,574. Controlling brakes on motor vehicles and tractors. FEARN, H. March 12, 1943, No. 4026. [Class 79 (v)] In a tractor or vehicle having a pedal 10 which first releases the clutch and then applies the brake, readily releasable means for holding the pedal in the brake-applied position comprise an upstanding hand-lever 11 or 16. In the construction shown in Fig. 1, the clutch- and-brake pedal 10 has pivoted thereto a handlever or rod 11 sliding through a slot 12 in a bracket 13. When the pedal is depressed to apply the brake, the rod slides down through the bracket until a notch 14 engages in the bracket and prevents the return of the pedal, thus holding the brake applied. To release the pedal, the rod 11 is moved sidewise against the action of a spring 15, to release the notch from the bracket, thus leaving the pedal free to rise. In the construction shown in Fig. 3, a hand lever 16 is formed with a catch 16b adapted to ride over and hold the pedal 10 when the latter is pressed. The lever is pivoted at 17 on a bracket 18 adjustably mounted at 19.

Abstract: 139,288. Gates, C., and Gates, E. C. Feb. 18, 1919. Optically-projected signals.-An advertising and like apparatus particularly adapted to be used in kinematograph theatres &c. comprises an optical lantern automatically intermittently operated and a screen combined with a clock. The screen comprises a clock face m. Fig. 3, and a central disk i<1> between which emerge the hands h<1>. The slides bearing the advertisements are carried on a disk b which brings them in turn to the correct position in a lantern g. The disk b is mounted on a shaft c rotated by a spring, electric, or other motor d. On the shaft c is fixed a slotted disk e with the slots f of which engages a catch k<4> on a pivoted U-member k. One arm of the member k carries an armature k' for attraction by an electro magnet j and the other arm k<5> engages a wind vane &c. d<1> to stop the motor d. In operation, contact is made at intervals by the clock in the screen to energize the magnet j, thus raising the catch k<4> and the arm k<5> and allowing the motor d to rotate the disk b. The catch k<4> soon falls and, when the next slot f comes beneath it, enters the slot and the arm k<5> drops to engage the vane d<1> to stop the motor and retain the slide in display position. Three methods of energizing the magnet j are shown; (a) by putting the magnet in the lantern lighting circuit and shunting it through the clock switch, so that considerable current flows through the magnet only when said switch is broken; (b) by putting the magnet in a circuit containing lamps q, at the corners of the screen, and the clock switch, so that when the switch is made the lamps q are lit and the magnet energized; (c) by putting the magnet in a separate battery circuit with the clock switch. The advertisement l thrown by the lantern takes the arrangement of the usual clock-face numerals. and the main body of the screen aud the central disk i<1> may bear permanent advertising matter t, t<1>.
Patent GB-752361-A (GB)
Title: Method of preparing compact bodies of tough heat-resistant and light materials
IPC: C04B35/56
Filed: 1954-02-11
Abstract: A titanium carbide body is produced by forming a mixture of titanium carbide TiC and 10-35 per cent of titanium hydride, compressing into briquettes, heating to a temperature sufficient to decompose the hydride, e.g. 1000 DEG C. in an atmosphere of hydrogen or a rare gas such as argon, crushing to powder, compressing the powder to the required final shape and finally heating in an atmosphere of hydrogen or a rare gas at a temperature above 1800 DEG C.  Intermediate heating and crushing may be dispensed with in high titanium carbide mixtures, e.g. 90 per cent titanium carbide, if heating up to 1000 DEG C. is sufficiently slow.  Instead of moulding to the desired final shape, a roughly moulded mass may be heated to about 1300 DEG C. machined to the desired shape, and then sintered to the desired final temperature. When using a hydrogen atmosphere graphite parts may be coated with aluminium to prevent reaction with hydrogen. Alternatively heating may be effected in a current of hydrogen up to a temperature of 1000 DEG C. and then substituted by argon. According to the Example a product having a density of 4.85 gm./cm3 and a hardness of 1,500 kg./mm.2  Vickers is obtained.

Title: Preparation of wood for bending
Inventor: TURNER NORMAN
IPC: B27H1/00
Filed: 1961-02-03
Abstract: 965,451. Bending wood. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 2, 1962 [Feb. 3, 1961], No. 4215/61. Heading B5L. Wood is prepared for bending by softening it by steaming or boiling, compressing it longitudinally along the grain and then releasing it while still hot from the softening treatment and allowing it to cool while free of any longitudinal compressive force. The amount of compression should be from fifteen to thirty per cent of the initial steamed length. In making D-shape space handles, about two-fifths of the length of the wood piece is steamed or boiled and the complete bundle is slid into a fitting tube, say of 10 gauge brass. An hydraulic plunger then applies an axial load of 3000 lb./ sq. inch or more until a projection on the plunger operates a switch to control the supply of hydraulic fluid when the required degree of compression has been reached. The handle is then withdrawn and allowed to cool, and is then tapered, saw cut, riveted to prevent splitting, bent to the required shape and fitted with a cross-piece. The moisture content of the compressed wood should be at least twenty per cent before it is bent.

Title: Improvements in or relating to magnetic deflectors for electric arcs in lamps, searchlights and the like
IPC: H05B31/00
Filed: 1919-02-20
Abstract: 137,937. Yorke, J. P. Feb. 20, 1919. Arc lamps.-An arc deflector or centralizer for a projection or other lamp comprises two or more magnet or solenoid poles disposed on each side of the arc so that the fields crossing the arc tend to restore it when displaced from its normal position. As shown, two horseshoe magnets 1, 2 are placed on opposite sides of mutually inclined electrodes 10, 11, with unlike poles in corresponding positions. Instead of being situated in planes paralle with the electrodes, the magnets may be in a transverse plane, with poles facing each other. The magnets are covered with asbestos 7, on which are wound a few turns of a conductor in series with the arc, the part 12 of the conductor leading from the negative holder being flexible. Each magnet is mounted on a spindle 3 or 4 capable of rotation and sliding in bearings 5. One spindle may extend outside the lamp and be provided with a milled head for adjustment, the two magnets being non-magnetically coupled by the conductor or by a special piece so as to move simultaneously. Alternately, the magnets may be adjusted as described in Specification 129,680. The invention is also applicable to lamps with alined electrodes.

Title: Improvements in or relating to conveying and feeding mechanism for bottles, jars, cans and other containers
IPC: B08B9/42
Filed: 1932-02-15
Abstract: 392,677. Conveyers for bottles &c. WEBSTER, R. W., Abbey Iron Works, Waltham Cross, Hertfordshire. Feb. 15, 1932, No. 4438. [Class 78 (i).] Relates to conveyer apparatus in which bottles or other containers are transferred from a conveyer A by a notched disc B to a transverse conveyer C from which they may be discharged in rows into tipping cradles and delivered on their sides to cradles V, from which they are pushed into carriers Ion endless chains for passage through washing, pasteurizing, sterilizing or like apparatus. The conveyer apparatus is of the kind in which part 16a of the guard of the feed disc is pivoted and may yield if a bottle jams, thereby operating mechanism which interrupts the action. The disc B is driven from the main shaft 2 through a pin clutch at 5 which is operated by movement of the pivoted guard rail 16a. This rail is extended at 16b to form part of the side rail if the conveyer A. The arrangement is such that the feed disc B is stopped without stopping the conveyers and can only be restarted in phase with the other parts of the apparatus. The feed disc comprises two parallel plates spaced apart, so that if a bottle on the conveyer A falls on its side neck forward, it will pass under the upper disc B up to the shoulder and will in this position bear on the guard 16b and operate the clutch mechanism. As shown, the disc B has a plain portion B<1> as well as the set of notches, in order to interrupt the delivery and allow time for the transfer of a row of bottles from the conveyer C to the carriers I, but this plain section may be dispensed with if the transfer mechanism operates quickly enough. A timing finger 21 is operated by a notched disc D to control the feed of bottles from the conveyer A to the disc B. Outward movement of the guard 16a, 16b on its pivot 17 moves a slotted rod 14 against the action of a spring to withdraw a catch 13 from a lever 9c ; this lever is moved to the left by a spring 15 and permits movement counterclockwise of a threearmed lever 9b, 9a, 7 under the action of the rod 14 and a spring 12. This movement withdraws the pin 5d of the clutch as soon as a toothed wheel 8 on the member 5b of the clutch, which is connected with the feed disc B, is in position to receive the lower end of a rod 11 linked to the arm 9a. In resetting the catch 13, the clutch-member 5b is held by the rod 11 until the pin 5d is re-engaged.
