Title: Bonding thermoplastic sheets
IPC: B32B15/08
Filed: 1964-04-22
Abstract: Compositions which may be formed into sheets capable of bonding to metal surfaces comprise a vinyl polymer, a non-polymerizable plasticizer therefor, a polymerizable plasticizer and a catalyst for the polymerization thereof.  The vinyl polymer may be a vinyl chloride polymer or copolymer.  The non-polymerizable plasticizer may be a phthalate or adipate, or an ester of a long-chain alcohol.  The polymerizable plasticizer may be diallyl fumarate, diallyl maleate, diallyl phthalate, diallyl methyltartronate, allyl methacrylate, tetrahydrofurfuryl methacrylate, trimethylolpropane trimethacrylate, ethyleneglycol dimethacrylate, triethyleneglycol dimethacrylate, tetraethyleneglycol dimethacrylate, polyethyleneglycol dimethacrylate cyclohexyl methacrylate, dibutyl fumarate or dibutyl maleate. Specified catalysts are benzoyl peroxide and t.-butyl perbenzoate. The compositions may also comprise stabilizers, e.g. lead salts, and fillers, e.g. calcium carbonate, magnesium carbonate, magnesium silicate or kaolin. The compositions may be formed into sheets under such conditions that the plasticizer remains substantially unpolymerized and the sheets applied to metal surfaces under heat and pressure so that polymerization of the plasticizer and bonding to the metal surface take place.  Good bonds are obtained to steel, copper and aluminium surfaces.  Examples describe the bonding to metal surfaces of sheets formed from compositions comprising polyvinyl chloride, diisodecyl phthalate, dibasic lead phthalate, lead bicarbonate, filler, t.-butyl perbenzoate and (1) diallyl tartronate, (2) diallyl phthalate and (3) diallyl fumarate.

[Also in Group XXV] In an apparatus for wrapping flat paper, fabric or other strip about an electric conductor, a reel 1 of strip is mounted on a spindle 6 which is in turn mounted on an arm 2 which rotates about a tubular member 5 through which the conductor passes. A tension control comprising a drum 9 is attached to the spindle 6 and a brake shoe 8 co-operates with the drum. The brake shoe 8 is carried on an arm 12 which may be reciprocated in a guide 15, the arm 12 being pivotally connected to one end of a bellcrank lever 11. A tension spring 10 urges the brake shoe 8 against the drum. A balance weight 13 is mounted on the bell-crank lever, its position being adjusted so that the braking force exerted on the strip by the brake shoe 8 at low speed is equal to the tension produced in the strip at high speed due to frictional and other forces, for example, frictional forces acting on the bearings of step guide rolls. The weight is such that at high speed the centrifugal force on the weight due to rotation about the tubular member 5 balances the force of the spring 10 and no braking is effected. A further brake operating on the same drum 9 is included to supply normal running tension. The spring, bellcrank lever 11, and guide 15 are mounted independently of the drum 9 on apparatus extending from the frame 2.

Title: Improvements in or relating to apparatus for perforating apertures in flexible discrete elements of a sheet-like nature
IPC: G03B21/11
Filed: 1958-02-11
Abstract: 883,420. Selective punching - machines. KODAK CO. Feb. 11, 1958 [Feb. 11, 1957], No. 17201/61. Divided out of 883,419. Class 31 (2). Apparatus for perforating flexible discrete elements of a sheet-like nature, comprises a plurality of punches, movable control elements for determining which of the punches are to be rendered effective for perforating an element, a support for a discrete element to be perforated provided on a transport means movable in planes perpendicular to each other such that movement of the transport means in one of said planes will bring the element on the support into contact with the selected punch or punches which are thereby caused to make perforations in the discrete element, said selected punch or punches entering a corresponding die aperture or apertures provided in the support. The perforating machine is described as applied to the optical viewing apparatus described and claimed in Specification 883,419 for punching out holes corresponding to those images of an image bearing element which it is desired to reproduce. The machine comprises a holder 210 accommodating slides 214, each connected by a flexible cable 218 to a selector button (not shown). The slides 214 are movable across a fixed part 212 in which punches 217 can slide when overlain by a notch 219 in its associated slide 214. In use, the slides corresponding to those images which it is not desired to reproduce are moved by the cables 218, so that the notches on said slides overlie the associated punches 217. Thereupon a perforated plate 105 carrying the image bearing element is pressed by a rubber cap on the armature of a solenoid, which is momentarily energized when plate 105 is correctly positioned, against the punches so that those punches which are prevented from movement by the slides 214 perforate the image bearing element. A switch is also closed to energize a solenoid and so connect a vacuum pump to a recess in the perforated plate and remove the perforations to a drip jar. Slides 214 and punches 217 are re-set by a rotary solenoid 229 (Figs. 2 and 9, not shown), which rotates a cam into engagement with the ends of slides 214, this solenoid being energized when plate 105 is removed from the perforator.

Patent GB-173198-A (GB)
Abstract: 173,198. Haddan, A. J. H., (National Cash Register Co.). Sept. 16, 1920. Tablet indicators; printing totals.-Relates to cash registers, particularly those of the key-set, key-operated type described in Specification 142,436, in which a customer's totalizer is zeroized for printing a total, and consists in means whereby the indicators may be dropped or not as desired when a total is printed, and further, in an alarm actuated by the totalizing crank. On depressing a key, a lug 256 on the indicator 255 is raised above a flange 257 on a frame 258 rocked by a cam 263 fast on a shaft 261 which acts against a roller 262 on a pitman 259 pivoted to the frame and having a slot straddling the shaft 261. The operation is timed so that the flange returns by the action of a spring 285 to the path of the lug to retain it in the raised position. On printing a total, the raised indicators may be dropped or not according to the position of a knob 264 on the end of a horizontal rod 265 which has two notches 269. 270 receiving a spring-controlled pawl 271. Fast to the other end of the rod is a bar 273 extending to the rear of the machine and having a slot 274 engaging with a stud 275 mounted in the side frame 34. The bar 273 has an upwardly-extending portion 276 carrying a stud 277 engaging in a slot 278 of a vertical rod 279, the upper end of which has an elongated opening 280 engaging with a pin 281 on an arm 282 fast on a shaft 222. Actuation of the totalizing crank rocks the shaft 222 as described in Specification 173,197, causing the bar 279 to move downwards and then return. When the pawl 271 is in the slot 269, an ear 283 on the bar 279 contacts with a pin 284 and causes the member 258 to rotate, allowing the raised indicators to fall. When the pawl is in the slot 270, the bar 279 is moved sufficiently to allow the ear to pass the pin, and the indicators are not disturbed. The alarm device is actuated by the action of a pin 236 on a rocking bar 235, which actuates the total-printing operation counter 230 described in Specification 173,197, against an arm 246 pivoted on a yoked member 244 and normally held against a pin 245 by a spring 242. The right-hand side 249 of the yoked member is in the form of a bell-hammer which strikes a bell 250 on the return movement due to a controlling-spring 248.

A powder-filled cartridge fuse has a number of elements connected in parallel, one or more of which has an inherently different fusing characteristic from another or others of the elements but all of the elements have similar current-carrying characteristics and fuse simultaneously under short-circuit. In Fig. 1, the end caps 8 of the cartridge enclose metal blocks 9 to which the elements are connected. Three elements 11 ... 13 are shown consisting of silver strip with reduced centre portions having holes 16 to ensure optimum short-circuit operation. The strips carry equal proportions of current and strip 12 is severed at 17 and united by low-melting-point material 18 which causes the strip to fuse first on moderate overload, the proportion of current diverted to the remaining strips then causing them to fuse. It is stated that this construction results in a low fusing factor. Instead of severing the strip, indentations may be provided on opposite sides or the strip may simply be surrounded by a blob of low-melting-point metal. Fig. 5 shows a modification wherein a compression spring 20 located between projections 21 on the strip 12 pushes apart the ends of the strip on fusing. An indicator plunger 22 is provided operated either by release of tension in a wire 27, Fig. 5, or by fusing of a wire 25, Fig. 1. Fig. 6 shows another embodiment wherein strips 11, 13 are formed of silver and strip 12 is formed of tin, the cross-sections of the strips being such that they have equal resistances.
