Title: Improvements in or relating to a method of and mechanism for feeding folded sheets to sheet opening devices in a sheet handling machine
IPC: B65H5/30
Filed: 1931-02-14
Abstract: 371,087. Opening out folded sheets. POLLAK, J. E., 20, Holborn, London.- (Brehmer Geb. ; Plagwitz, Leipsic, Germany.) Feb. 14, 1931, No. 4777. [Classes 89 (iii) and 112.] Relates to mechanism comprising inverselyrotating suction rolls for opening out folded sheets or book sections in sheet handling machines, and consists in arranging the mechanism so that the leaves of the sheet are initially pasted from one corner thereof. As shown, folded sheets S from a stack A are fed individually, for example by mechanism as described in Specification 364,768, [Group XVI], to conveyer tapes 21. These co-operate with tapes 25 to feed the sheets to rotary suction rolls 16, 17. In order that the suction rolls may open the sheets out from one corner, the sheets are caused to assume an oblique position, Fig. 2, on the tapes 21 by engaging with obliquely-arranged stops 39 carried by pivoted arms 40. The stops, after they have turned the sheet as required, are moved to inoperative position by a bell-crank lever 33 and linkage from a cam on the main shaft 38. Simultaneously, feed rolls 30 on pivoted arms 31 are moved by the lever 33 into a position where they co-operate with the tapes 21 to maintain the sheet in its oblique position. Means other than stops may be employed for obtaining the obliquity of the sheets before they reach the suction rolls ; for example, the suction rolls, tapes, or sheet stack may be placed at a suitable angle relatively to the other parts of the mechanism ; or an oblique side guide provided with a cross-moving conveyer belt may be arranged to engage and swing the sheet.

Patent GB-591221-A (GB)
Title: Improvements in and relating to methods of preparing silicone resins
IPC: C08G77/06
Filed: 1944-03-16
Abstract: Silicone resins having improved electric resistivity, flexibility, and resistance to crazing are obtained by hydrolizing a mixture of organo-silicon halides by slowly adding a solution thereof in an inert aromatic solvent, e.g. toluene, benzene, xylene, to a mixture of said aromatic solvent, tertiary amyl alcohol, and water, recovering from the resultant mixture an organic solution of the hydrolysis products and heating the solution in contact with a hydrated metal halide as catalyst under conditions to distill off partially the solvent and volatile components of the mixture. Hydrated metal halides specified are ferric chloride, ferrous chloride, stannic chloride and are preferably used in admixture with other catalysts, e.g. antimony pentachloride, aluminium chloride or anhydrous ferric chloride. The process is particularly applicable to methyl phenyl silicones obtained by hydrolysis of suitable methyl silicon halides, phenyl silicon halides and silicon tetrahalides, e.g. as described in Specification 585,628.  In examples: (1) an intermediate methyl phenyl silicon obtained by reacting silicon tetrachloride, phenyl silicon tetrachloride, diphenyl silicon dichloride, methyl silicon trichlorides and dimethyl silicon dichloride in a mixture of toluene, tertiary amyl alcohol and water was washed and centrifuged to remove acid and then partially distilled in presence of 5 per cent antimony pentachloride and 3 per cent hydrated ferric chloride.  A hard glass film which cured on glass tape at 200-300 DEG  C. was obtained which had improved characteristics as compared with the same film obtained by completely removing the solvent.

Title: Improvements in and relating to winding machines
IPC: B65H54/14
Filed: 1925-04-28
Abstract: 257,498. Joyce, J. D. April 28, 1925. Winding-machines; stop-motions; spindle-driving apparatus; stop-apparatus, non-automatic.- In a traverse mechanism for a winding-machine, the traverse arm which reciprocates the threadguide is driven from a rock-shaft by a clutch which is disconnected when the bobbin is fully wound, or when the thread breaks. The drive shaft 1, Fig. 1 drives a countershaft which is journaled in a casing 1<a>, and carries a cam which actuates rock-shafts 8. Frictionwheels 9 on the shaft 1 drive wheels 10 slidably keyed to shafts 11 which carry cop-spindles 12. An arm 20, Fig. 3. which is rocked by the shaft 8 through a clutch 17, reciprocates a bar 22 which actuates bars 23, 24, the former of which carries a shaper plate 26. A screwed threadguide rod 25, Fig. 1, slidably pivoted at one end 82, is pivoted to slide laterally at its other end in a slotted plate 28 on the rod 24. The thread-eye 14<a> is fixed to a spindle 41, an arm on which carries pins embracing the arm 44, Fig. 3, carrying the eye 14<b>. On a stud 45, Fig. 3, is slidably journaled a collar which carries the arm 44 and an arm 46. If the thread breaks, the thread-eye in use falls and rocks the, arm 46 into position between a collar 47 on the reciprocating rod 24 and an arm 49 fixed to a stud 48. The relative positions of the parts are such that on its next reciprocation the collar 47 forces the arms 46, 49 to the right, so that a collar 50 fixed to the stud 48 passes from under an arm 51 on a spindle 18. An arm 55 on the spindle 18 thereupon disengages the clutch 17 to stop the reciprocation of the rod 25. An arm 69 on the spindle 18 is also lowered to allow an arm 61, Fig. 5, on a stud 60 to be rocked by a spring 52. A hooked arm 64 on the arm 61 thereupon rocks a clutch-member 66 on the shaft 11 against a weight 70, Fig. 1, to allow a brake-arm 62 on the stud 60 to slide the wheel 10 away from the wheel 9, against springs 77, and stop the wheel 10 and the spindle 12. When the cop is fully wound, an arm 75 on the thread-guide carrier engages an arm 76 on the spindle 41, Fig. 1, to rock the spindle and so stop the rod 25 and the spindle 12. By the action of the shaper plate 26 the cop is built up with conicity at both ends. The spindle 41 may be manually rocked to stop the mechanism. In a modification for building a cop which is cylindrical at the starting end, the members 22, 23, 24, 26, 28, are dispensed with and the rod 25 pivoted direct to the arm 20. Both thread-eye arms may be attached to the spindle 41 to which the arm 46 is also fixed. The clutch 66 and the springs 77 may be replaced by a compression spring, in which case the arm 64 is dispensed with.

Filed: 1963-02-07
Abstract: <PICT:1038954/C6-C7/1> Apparatus for washing and/or grit blasting metal articles such as castings comprises means for transferring the articles from a processing line onto an article carrier mounted radially, tangentially or at an angle along the periphery of a rotating tipping device, the orientation axis of the carrier being at an angle to the axis of rotation of the tipping device. The articles are locked in the carrier and intermittently or continously rotated from the processing line through 360 degrees or less to various process stages such as spray or dip washing, deburring, rinsing, drying and draining and then transferred from the carrier back to a continuation of the main processing line.  As shown in Fig. 1 a rotary device 2 has four article carriers 3 mounted on side frames 5 and secured to a rotating centre shaft or bearing 6.  The articles are transferred radially from the main processing line to the carriers 3 and then rotated through or to the various process stations.  Various indexing cycles can be operated and controlled by controller 30 e.g. rotation may be stopped every 90 degrees and the carrier may also be rotated over and back instead of around in one direction. The article carriers may also be mounted with their orientation axes disposed chordally or tangentially to the axis of rotation (Figs. 3 and 4 not shown). According to further embodiments (Figs. 6-9, not shown) the carriers are mounted with their orientation axes at an angle to the axis of rotation, which axis bisects the angle or its supplement, between the main processing line and its continuation. Furthermore the axis of rotation may be at some angle other than 90 degrees to the rest of the device.

Abstract: 456,801. Electrically - controlled locks. DAVEY, W. C., 176, Tottenham Court Road, London. Feb. 20, 1936, Nos. 5115 and 12638. [Class 44] To enable a lock tc be released from a distance the striking plate is pivoted anc normally held fast by locking-means releas able by a solenoid the locking means be ing engaged in its un locked position by a mechanical catch which is released by the closing of the door Mounted in an E- shaped casting 1 is a T-shaped plate 2 pivoted about pins 3 and normally retained in the position shown by a pin 6 passing through a solenoid 4 and engaging a recess in the plate. When the solenoid is excited the pin 6 is raised and its head is engaged by a pivoted catch 8 on a swinging member 9 which is retained in its normal position by springs 22. The bolt of the lock can then turn the plate 2 as the door is pushed but on reclosing the door the plate 2 is returned to its normal position, aided by spring-pressed balls 10 and the member 9 is swung laterally to permit the pin 6 to fall and re-engage the plate 2. In a modification the pivoted catch 8 is carried by an extension of the pivot of the striking plate 2 and turns therewith, a horizontal plate on the top of the striking plate preventing the pin from dropping further until the plate 2 occupies its normal position. Instead of locking the plate 2 directly, the pin 6 may actuate a pivoted catch 15, Fig. 10, which engages a projection on the plate 2. When the pin 6, which is loaded by a weight 20, is raised by the solenoid the catch 15 is raised by a spring and the door as it opens can then turn the plate 2 until one edge engages a recess in a pivoted spring-pressed lever 17. As the door closes the end of the lever 17 is struck to release the plate 2 which is returned by a volute spring 21 acting on the pivot extension which carries the pivoted detent 8.
