Title: Improvements in or relating to glass seals
IPC: H01J5/24
Filed: 1941-12-01
Abstract: 553,746. Welding glass ; electric discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 1, 1941, No. 15438. Convention date, Nov. 30, 1940. [Class 56] [Also in Group XL] Relates to a method of sealing a glass disc across the open end of a glass envelope, particularly for sealing the bulb of a thermionic valve to a glass disc into which conductors are sealed. According to the invention, contiguous edges of the bulb and the disc are heated to a temperature at which they fuse together, the central part of the disc being cooled during the heating operation. In carrying out the method, the disc 3 is placed on a vertical chuck 5 which has wells n to receive the ends 4 of the conductors. A glass bulb 1 is placed over the electrode assembly, a separate overhead collet being provided if required to hold the bulb in correct position. The chuck is rotated and is heated by gas flames 8 in order to heat the disc 3 by radiation, but the disc may be heated before being placed on the chuck. Gas flames 7 are also directed against the rim of the bulb to fuse it to the edge of the disc, and at the same time the central area of the disc is cooled preferably by blowing air through a bore 9 in the chuck spindle. Alternatively, the disc may be cooled by contact with the centre of the chuck, or by blowing air through the lower ends of the wells n.
Patent GB-747969-A (GB)
Title: Coated or laminated sheets having a surface of thermoset synthetic resin
IPC: D21H23/44
Filed: 1953-06-04
Abstract: A coating or covering layer of thermoset synthetic resin is formed on a sheet material of vegetable origin such as wood, plywood, fibreboard, or paper by covering the sheet with a thin layer of thermosetting resin in the form of powder or fibres, exposing at reduced pressure to the vapour of a solvent so that the resin swells but does not dissolve, and subjecting the assembly to low pressure in a heated press having a resilient lower plate on which the uncoated side of the shee material is laid.  When the sheet to be coated is thin or porous, it is rendered non-porous, while remaining matt and rough, by impregnation with thermosetting synthetic resin which is hardened before the coating operation.  The synthetic rosin may be phenol-, cresol-, xylenol, urea-, dicyandiamide-, or melaminealdehyde resin, and the solvent vapour may be ammonia, an aldehyde, an alcohol such as ethyl alcohol, or a ketone such as acetone.  The resilient lower plate of the press may consist of a non-resilient plate with a covering of paper, cardboard, felt or a heat-resisting, rubber-like material.

Title: Improvements in textile stentering machines
IPC: D06C3/00
Filed: 1948-06-09
Abstract: 652,773. Finishing fabrics. SPOONER, W. W. June 9, 1948, No. 15499. [Class 42 (i)] In a stentering-machine, the end sections of the chain rails which are situated at the entry to the machine are each displaceable with their supports, in accordance with any transverse displacement of a selvedge of the fabric fed thereto, by a traversing screw and nut mechanism, one element of which has a frictionwheel upon it adapted, under the control of an element co-operating with a selvedge of the fabric, to be brought into frictional engagement with one or other of a pair of continuouslyrunning friction rollers. As shown, Fig. 1, an end-section 13 of a chain rail support is secured to a framework 10 adapted to travel on rails 12 transversely of the machine. A traversing screw 21, normally held stationary, is carried in fixed bearings in the machine and is engaged by a nut 23 connected by a flexible coupling 24 to a sleeve 22 rotatably mounted in thrustabsorbing bearings 48 in framework 10 and carrying at its other end, in housing 20, a grooved friction-wheel 25, Fig. 2. Two grooved friction rollers 27, 33 are mounted on bell-crank levers pivoted on the axes of gears 29, 36, respectively, and are driven continuously in opposite directions by gearing from a shaft 19 connected to an electric motor 15. Rods 42 connect the horizontal arms of the bell-crank levers through resilient elements 46 to the plungers 43 of solenoids 44, Fig. 1. Both friction rollers are normally kept out of contact with wheel 25, but can be brought selectively into driving engagement therewith when one or other solenoid is energized. When the fabric is running true, both friction rollers 27, 33 will be disengaged from wheel 25; when a selvedge becomes displaced from a predetermined path, a control element in the form of a "spade" or photo-electric control causes one or other solenoid to be energized to bring one of the friction rollers into driving engagement with wheel 25 which then drives nut 23 in the appropriate direction until the desired displace. ment of framework 10 and rail support 13 is effected, whereupon the control ceases to operate, the solenoid is de-energized, and the drive is interrupted. A separate traversing gear is preferably applied to the end rail section at each side of the machine, the two gears co-operating with the same traversing screw, the two halves of which may be oppositely screwed. For adjusting the machine to operate upon a different width of fabric, motor 15 is disconnected, both solenoids are energized to clutch both rollers 27, 33 with wheel 25 and thus prevent rotation of nut 23, and traversing screw 21 is then rotated to effect the desired adjustment of the end rail sections, the rest of the rails being simultaneously and equally displaced by further screw mechanism geared to the traversing screw 21.

Title: Improvements in or relating to machines for moulding soles of rubber or rubber-like material on to shoe bottoms
IPC: B29C35/00
Filed: 1958-05-17
Abstract: 922,551. Moulding soles on to footwear uppers. BRITISH UNITED SHOE MACHINERY CO. Ltd., and F. C. CHOICE. May 19, 1959 [May 17, 1958], No. 15891/58. Class 87(2). A machine for moulding soles from rubber or rubber-like material and attaching them to the bottoms of shoes comprises a foot 2 for supporting the shoe, a pair of side moulds 4, a sole mould 8 arranged to be moved by power means between the side moulds, a " floating " member which the power means tends to move in a direction away from the shoe bottom when the sole mould is pressing the sole against the shoe bottom, and connections between this " floating " member and a carrier for the foot which on such movement of the member occurring, tend to exert an increased thrust on the foot to prevent its yielding under the thrust of the sole mould. In the idle position of the machine, Fig. 1, the cylinder 20 which forms the " floating " member is arranged to rest with its outwardly extending flange 26 resting on the shoulder 28 formed on the top surface of the stationary bearing member 24. The foot 2 is in a raised shoe loading position, there being a gap G 1  between the upper bridge member 10 and each bearing member 16. To lower the foot 2, the lower bridge member 12 which is connected with the upper bridge member 10 by tie rods 14 is urged downwardly by the pinion 34 being rotated by movement of the rack 36 to the left, the pinion 34 carrying eccentric pins 30 engaging within a block 32 which is slidable horizontally along a guideway provided in the portion 18a. Once the gap G 1  is closed the foot can be lowered no further but the pins 30 continue to rotate to a position 180 degrees from their initial position and as they cannot descend further, the shafts which support them rise to cause the cylinder 20 to be raised to form a gap G 2  between the flange 26 and the shoulder 28. For example, if the pins are arranged to descend 2“ inches but the gap G 1  is only 2# inches, the cylinder 20 will rise forming a gap G 2  of # inch. The side moulds are then closed and fluid pressure applied beneath the piston 22 to raise the sole mould 8. Any elongation of the rods 14 (within the limit allowed for by the gap G 2 ) will take place with an accompanying bodily movement of the cylinder 20, rather than by an upward movement of the foot 2. Consequently the welt plates 6 engage the shoe at a given, unvarying position and the formation of undesired indentation or marking of the shoe is avoided. In an alternative embodiment, the cylinder is supported on compression springs and is capable of limited heightwise movement with respect to the machine frame. Consequently, should there by any tendency for the tie rods to stretch, the cylinder moves downwards against the action of the springs thus leaving the foot undisturbed in its heightwise relation to the side moulds. Specifications 824, 106, 859, 671 and 922,552 are referred to.

Abstract: 636,902. Turret lathes. SCHLITTERS, M. J. June 17, 1947, No. 15952. Convention date, May 25, 1945. [Class 83 (iii)] A recessing tool-holder, particularly for screw machines, comprises a non-rotatable supporting member guided in a rectilinear path to and from the work, and carrying another member slidable on a face arranged at an acute angle with respect to said path, is characterized by a spring housed in one of said members and urging the supported member toward the work, means for adjustably limiting response of this member to said spring and stop-engaging means carried by this member, effective upon encountering a stop during advance of the toolholder towards the work, to induce a relative travel of the members along said cam faces, whereby the supported member is moved transversely to the tool advance. The supporting member 5 of the holder is provided with a shank 6 by which it may be secured to the main tool slide 7, Fig. 1, of an automatic screw machine. An inclined dovetail guideway 9, Fig. 7, is provided in this member for the supported member 4 which carries a tool-bar 2 with a recessing tool 1, Fig. 4. A spring 21 is interposed between these members, the tension in which can be adjusted by a screw 19. A head 20 on this screw acts as an abutment to limit the sliding movement of the supported member effected by the spring. A block 24 secured in a recess in the supported member carries at one side a roller 27 and on the other side is provided with a bore through which an operating rod 29 is adapted to pass. This rod is pivotally anchored at 31 to a stationary part of the machine and at the other end is provided with nuts 30 which are adjustable to stop the supported member at a predetermined point to start the transverse movement or recessing operation of the tool 1. The tool 24 is reversible so that the roller 27 may effect the stopping of the supported member by contacting a bracket fixed to the headstock end of the machine.
