Title: Improvements in or relating to machines for forming and pressing metal sheet and profile elements
IPC: B21D22/00
Filed: 1956-10-22
Abstract: 823,796. Stretching; upsetting; stamping. ECKOLD, W. Oct. 22, 1956 [Aug. 30, 1956], No. 32161/56. Class 83 (4). A machine for forming and pressing, e.g. to stretch or upset, sheet metal having a press tool reciprocated at high speed is characterized in that the press tool is driven by a floating double-ended lever oscillating by rolling over the surface of a pressure pad mounted in the machine housing. A tool 12, of the type having jaws moved apart or together as the tool as a whole moves at right angles to the movement of the jaws, co-operates with a similar but fixed tool 12<SP>1</SP> to stretch or upset a blank 17 inserted therebetween as the tool 12 is reciprocated. The tool 12 is carried by a hollow cylinder 13 reciprocated in the machine housing 1 by an oscillated lever 2. One end 2<SP>1</SP> of the lever 2 is freely hinged to a flexible plate 3 resiliently held, on or off centre, on edge in the cylinder 13 in a rubber cushion 14 and a rubber spacer 16 bearing on the top of the end 2<SP>1</SP>. The other lever end 211 is carried by an eccentric 4 held against a driven pulley 9 by a roller arch 10 on a rubber torsion bush 10<SP>1</SP> and/or by pre-compressed rubber elements 8 secured to the lever 2 and to the housing 1. The pulley 9 may be eccentric and the wheel 4 not so and such members may be of plastic. The lever 2, as it is oscillated by the eccentric, rolls over a pressure pad 7, adjustable by a hand-wheel 6, against which pad the lever is urged by pre-compressed rubber blocks mounted between the lever and lugs 7<SP>11</SP> depending from the pad 7. A hardened insert on the lever 2 may bear on the pressure pad 7 and a ball may be seated between the lever end 2<SP>1</SP> and the plate 3. Two sets of press tools 12 may be driven from a common drive pulley through two eccentrics and two levers 2. In a modification, Fig. 8, an eccentric oscillates the lever 2 through a link 24 having a cylindrical contact surface 24<SP>1</SP> which rolls on the underside of the lever end 2<SP>11</SP>, rubber blocks in lugs 25 depending from the lever 2 keeping the parts in contact. To actuate two sets of press tools 12 the ends 2<SP>11</SP> of two levers 2 extending in opposite directions may roll on the surface 24<SP>1</SP>. The machine housing may be supported in a movable frame for different working positions.

Title: Improvements in or relating to electric switching arrangements
Inventor: LAMBERT RAYMOND ARTHUR
IPC: H05G1/56
Filed: 1954-11-08
Abstract: 792,111. Switching systems for X-ray apparatus. GENERAL ELECTRIC CO., Ltd. Feb. 8. 1956 [Nov. 8, 1954], No. 32263/54. Class 38 (4), In a system for effecting closure of an X-ray contactor at a zero point in the A.C. supply wave, as described in Specification 693,042, wherein the operating coil C of the contactor, or of a relay controlling an electronic contactor, is connected across the A.C. supply 2 in series with a half-wave rectifier 3 and the normallyopen contacts P1 of a control relay P, the relay winding, in series with a half-wave rectifier 1, is energized upon closure of an " exposure " switch 11 from the supply 2 through a phase shift circuit R5, R6, R8, R9, C7, C10 which effects such a phase displacement that the coil C is connected to the supply during a half cycle when its associated rectifier is non-conductive. In the system shown, successive energizations of coil C are arranged to commence during opposite half cycles of the supply and, for this purpose, an additional rectifier 4 and a hold-on relay H are provided, in addition to the contacts 13 of a relay responsive to, the polarity of the last half cycle of the previous exposure, such as is described in Specification 693,621. Assuming contacts 13 to have been left in closed condition by the previous exposure, the following sequence of operations occur as the result of closure of switch 11 to effect a new exposure: relay P picks up when rectifier 1 is conductive and locks in over P2; contacts P1 also close to allow energization over rectifier 3 in the next half cycle of relay H, contactor C, the clutch T of a timing motor and a non-repeat relay N. Contactor C closes its main contacts a half cycle later (as this is its operating time) to start the actual exposure and its auxiliary contacts C1 complete an energizing circuit for T and N independent of contacts P1 and H1. When relay H responds its contacts H1 short-circuit rectifier 3, so that the contactor coil C is then supplied with A.C. Response of N completes a holding circuit for itself at contacts N2 and deenergizes P at contacts N1 to prevent a further exposure should the timer contacts 12 reclose after opening to terminate the exposure. Should the contacts 13 have been open prior to closure of switch 11, energization of C, T and N would have been delayed half a cycle until rectifier 4, which is oppositely poled to 3, had become conductive, the rectifier being shortcircuited in the next half cycle by the auxiliary contact C1. In another arrangement, the contactor coil C is replaced by the windings of two relays fed through oppositely-poled rectifiers and controlling, respectively, the firing valves of a back-to-back ignition contactor.

The inner flaps 33, 34 may be cut or recessed to accommodate intermediate flap 32 so that both the peripheral portion of the inner flaps and the intermediate flap contact outer flap 31. Preferably, the laminate comprises a ply of paperboard 13 joined to a thinner ply of waxed paper 11, the thickness of the adhesive 12 being sufficient to allow extrusion without delamination. Various embodiments are described which include having slits in flap 31 only, short diagonal slits in flap 32 only, which extend through both plies, similar diagonal slits in flaps 33, 34 only with flap 32 lying innermost of the erected carton and in Fig. 14 slits 460 in ply 411 of flap 431 overlying slits 462 in ply 413 of flap 432 with additionally slits being provided in glue flap 425 (flap 25 of Fig. 3). Further arrangements with slits in both plies of the same flap or in different plies of different flaps are described. Simpler forms wherein an intermediate closure flap, such as flap 32 of Fig. 5, is provided with relatively large cut-outs or perforations are described and a number of embodiments show a reclosable carton provided with a tongue and slot closure as well as slits, the folding of the closure flaps 931-934 (Fig. 22, not shown) to closing position being undertaken in that order. A carton with lid is also described (Fig. 26, not shown), the body of the carton being held erect by overlapping side wall portions provided with slits and the lid being sealed in position by a flap having slits and hinged thereto which overlaps the front wall.

Abstract: 1,216,341. Moulding curved reinforced resin strips. H. J. REED. 17 July, 1968 [17 July, 1967], No. 32691/67. Heading B5A. [Also in Division B2] A method of making a resin-stiffened fabric strip of transversely curved form, comprises coating a woven fabric strip comprising interlaced yarns of filaments of glass or synthetic polymeric material with a heat-curable synthetic resin and imparting to the resin-coated strip a predetermined transverse curve during the heating of the said resin to effect curing thereof, the curving of the strip during heating being effected by a plurality of spaced pairs of concave and convex rollers of metal or other material between which the strip is passed as it traverses substantially horizontally a heatcuring oven, each pair of the said rollers consisting of a convex-shaped bottom roller positioned directly below a concave-shaped top roller, the former roller being driven, but the latter roller being a floating member, whereby the combined weight of the top rollers as the strip passes through the oven forms the strip to the predetermined curve transversely, the top roller of each pair of rollers being rotated by movement of the strip gripped therebetween. The synthetic resin may be an acrylic resin. A bonding agent may be applied to the fabric strip before applying the synthetic resin. A suitable material for this purpose is a silane. The synthetic polymeric material may be a polyester, polyamide, polypropylene, polyethylene, polyvinylidene chloride or vinyl chloride-vinyl acetate copolymer. A convenient curing tem perature range is 140-300‹ C. Several coats of the heat curable synthetic resin may be applied to the strip. The pairs of rollers may be spaced at varying distances, e.g. from 1¢ inches to 18 inches, between respective pairs. The semirigid strip, having been cured may be coated with a polyurethane-forming composition.
