Title: Improvements in or relating to Methods of Laminating Fabrics
IPC: B32B37/10
Filed: 1967-08-08
Abstract: 1,175,435. Laminating fabric plies. HERCULES Inc. 8 Aug., 1967 [17 Aug., 1966], No. 36457/67. Heading B5N. [Also in Division F2] A method of laminating plies of fabric comprises interposing between the plies an opennetwork thermoplastic sheet to produce a sandwich-like structure and, while maintaining the plies of the sandwich-like structure in contact, heating it to a temperature sufficient to melt the thermoplastic sheet by passing a hot gas, e.g. air or steam, therethrough. Exemplified fabrics are woven, knitted and non-woven fabrics of cotton, wool, regenerated cellulose, cellulose acetate, polyamides, polyacrylics and polyvinyls. The open network may be formed by moulding, by laying strands or threads at right angles, by weaving or by random laying of strands or threads, specified thermoplastic materials being polyethylene, polypropylene, polyesters, polyamides, ethylene-propylene copolymers, ethylene-vinyl acetate copolymers and ethylene-methyl methacrylate copolymers, many suitable configurations of the structure of the open network being shown. Tubular laminates may be made by placing the sandwichlike structure between two metal screens, rolling the resultant assembly into a tube, closing one end of the tube and forcing the hot gas through the assembly. In Fig. 14, fabric plies 25 and 27 and open-network sheet 26 are fed over the surface of perforated or screen drum 20, hot gas being forced through the assembly by fan 31 and pressure maintained by endless belt 21. Examples are given.

Title: Improved means for actuating electric switches
IPC: H01H17/00
Filed: 1920-12-30
Abstract: 157,079. Day, A. C. Dec. 30, 1920. Flexible pull actuation; cases.-Mechanism for actuating a tumbler switch, which may be combined with a ceiling rose, by means of a flexible cord which when first pulled closes the switch, and when again pulled and released opens it, consists of a hook-frame 4 pivoted on an extension of the tumbler pivot pin 3 and carrying pivoted upon it at 11 a hook-member 9, 15, and a catch-frame 5 also pivoted on the tumbler pivot, the tumbler knob lying between the hook-frame and the catch-frame. Wire springs are arranged on the pivots to hold the pivoted members in the positions shown. The operating cord 17 is secured to the pivot pin 11, or, in the case of dual cord operation as shown in Fig. 3, passes over a pulley 34 on the pivot pin and over a fixed pulley 33, the cord being provided with stops to prevent its being pulled into the casing, so that a pull on either cord will rock the member 4. When so rocked, the upper end of the hook-member engages the tumbler shank and is pressed back against its spring until it bears against the back of its frame when it positively drives the tumbler to the "on" position, shown in dotted lines. The lower end of the hook-member which is raised towards the member 4 during this driving movement passes idly through a hole in the catchmember 5, and, when the cord is released, the member 4 and the hook-member are restored bv their springs to the normal positions, leaving the switch "on." When the cord is again pulled, the hook 22<1> engages with the nose of the catchmember and, on releasing the cord, the catchmember is carried round driving the tumbler which in its movement frees the hook and the parts are restored to the positions shown with the switch "off." To secure the cover in place, a flange on the base is formed with projections 26, Fig. 5, on which a gapped flange 29 on the coverfits, bayonet-fashion, and an expanding spring ring 28 is arranged between the projections and the flange. The ordinary binding post 44a, Fig. 7. on the base, having a lateral screw, is modified by dispensing with the lateral screw, surrounding the post with a sleeve 44 through a notch in which the lead is passed laterally into the hole in the post and secured by a screw 45 passing axially into it,

Abstract: 1,240,716. Dispensing articles. VENDO CO. 7 Aug., 1968 [20 May, 1968], No. 37620/68. Heading A4T. A top delivery article dispensing apparatus comprises columns 36 each containing a stack of articles such as mint or gum; each column having an article support 76 including a leaf spring 78 connected to an elevator 62 reciprocable in a notch 60 in the column and including a bobbin 70 on which is wound a spring 72 that biases the stack upwardly to dispose the uppermost article adjacent a delivery station 84, and a delivery control structure 86. Each structure 86 is rotatable on a common shaft 48 and includes elements 90 that normally retain the stack in the column, as shown in Fig. 6, and a selection solenoid 98 provided with an armature 100, said armature being movable to and from the path of travel of a drive arm 102 rigidly fixed to a shaft 48. On coin deposit and actuation of a selector push button switch (34), the associated selected solenoid 98 is energized and its armature operates an associated switch (112, Fig. 3) which energizes a common vend solenoid (120, Fig. 2). A cable 124, Fig. 2, connected to the armature of solenoid (120) is wound about a pulley (54) on shaft 48 and connected to a tension spring (122), so that when solenoid (120) is energized it drives shaft 48 clockwise, Fig. 8, and spring (122) is loaded. Thus arms 102 are rotated clockwise and extended armature 100 of selected solenoid 98 is interlocked with its associated arm 102 so that structure 86 is rotated clockwise therewith. Retaining elements 90 are withdrawn and the stack moves up till the uppermost article engages stops 118 as shown in Fig. 8. On release of selector switch (34), vend solenoid (120) is de-energized and spring (122) returns shaft 48 to its normal position. The previously rotated structure 86 is rotated anticlockwise, Fig. 8, with the arms 102 since tabs 116 on arms 102 overlie posts 96 of structures 86. Elements 90 eject the uppermost article into a common shoot 30 down which it gravitates to an accessible station (32, Fig. 1). A window (26, Fig. 1) permits viewing of the uppermost article in each column. The columns are pivotally suspended as a unitary structure by brackets 46 on shaft 48 so that they can be swung to a horizontal position (Fig. 2) for bottom loading, the columns being maintained horizontal by catches (132, Fig. 2) engaging notched lugs (138) carried by struts (140) pivoted (at 141) to the columns and constrained to move in slots (142). The fresh stack is introduced through open bottom 130 and pushed up to spring 78. Elevator 62 is pulled downwardly and the spring 78 is flattened against the elevator (Fig. 10) which thus snaps past the inserted stack to a position therebeneath where spring 78 returns to its normal support position.

Title: Controlled method for the production of clad glass rod
IPC: G05D5/03
Filed: 1975-09-15
Abstract: 1532424 Controlling manufacture of glass rod PILKINGTON BROS Ltd 7 Sept 1976 [15 Sept 1975] 37831/75 Heading G3R Glass rod 3 of uniform diameter is produced by drawing the rod from a glass melt 2 while sensing the rate of drawing and the diameter of the drawn rod, and using these values to control both the speed at which the rod is drawn from the melt and the position of the cooling means which solidifies the rod. The apparatus is for making clad glass rod i.e. rod having a core of one glass and an outer skin of another. The rod 3 is made by drawing from a reservoir 2 containing the two glasses in separate layers one on top of the other. The cooler 5 is movable towards and away from the surface to control the diameter of the rod. As the glass level falls the cooler must be lowered. The diameter of the rod is sensed by a transducer 6, the output 9 of which is compared at 11 with a pre-set voltage 10. The difference signal is displayed on a meter 12 and also applied to a proportional plus integral controller 13, the output 14 of which is fed via line 28 and summing amplifier 16 to control the speed of motor 7 which drives the draw rollers 8. This is a high-gain control loop by which the speed is regulated by the signal proportional to the diameter of the rod. A manual speed control signal can be applied to the amplifier 16 over line 15. The movement of the rod is converted by digitizer 17 to a pulse train, the frequency of which represents the speed of the rod. These pulses are used in a coarse open loop control system for the cooler drive motor. For this purpose the pulses are applied to a digital curve generator 18, the output of which is a changing signal adapted to cause controller 19 to drive the cooler downwards as the glass is used up, to maintain it at a given distance above the surface. The cooler is caused to deviate from this distance by signals on leads 24 and 27 derived from the high gain control loop so that the cooler is raised or lowered in order to keep the rod diameter and the drawing rate both constant.
