Title: Improvements in or relating to sheet bending and other rolls
IPC: B21D5/14
Filed: 1960-11-16
Abstract: 960,708. Curving. A. FERRANTI. Nov. 16, 1960 [Nov. 16, 1959], No. 39414/60. Heading B3E. A sheet bending machine comprising a set of three rolls rotatably mounted in a frame, one of which rolls is displaceable relatively to the other two rolls, has a curved guide mounted at one or each end of the displaceable roll and adapted to guide along a curved path a bearing support at the corresponding end of the displeaceable roll. Two lower rolls 14, 15 are driven by one motor (not shown) and an upper roll 16 on end shafts 17 is driven through friction clutch means 62, 72 from a gear 64 driven by a motor-reduction gear unit 68. The end shafts 17 are each mounted in a bearing 18 in a carrier 20 which latter comprises a lower part 24 and an upper part 22 connected by a pivot 26. The part 22 is of semicylindrical shape at 30 where it is accommodated in a corresponding seat 32 in a frame 34. The part 24 is guided by a lower wall 38 in the frame 34 to pivot about the upper seat 32. Such pivotal adjustment is effected by a worm 48, driven by a motor 50, rocking a fork 51 about a pivot 44 on the frame 34, the fork 51 embracing the shaft 17 where it is supported by an extension 52 of the bearing part 24. Adjustment at each end of the roll 16 is synchronized and is made at the beginning of the bending, the roll being thereafter moved back to its central position. For bending into conical form the adjustment is effected in opposite directions at opposite ends. The bearing carriers 20 could be adjusted by hydraulic means. The frames 34 are adjustable vertically on guides 36. Specification 960,707 is referred to.

Abstract: 909,754. Pianofortes. HAMMOND ORGAN CO. Nov. 17, 1960 [Dec. 16, 1959], No. 39490/60. Class 88 (2). A pianoforte includes a switch contact 12 attached to and movable with one of the damper heads 10 of the pianoforte and adapted to cooperate with a second contact. The switch is normally closed, but is opened on depressing the sustaining pedal 18. The second contact is preferably the respective pianoforte string 22. The first contact 12 is preferably a wire wound on the damper head 10. The switch is used for controlling the decay of tones produced by an electrical musical instrument to be played in conjunction with the pianoforte. The electrical musical instrument has pedals 34 which operate switches to tune a generator 36 of bass tones. The pedals also operate switches 40, 41. On depressing the sustaining pedal 18 and one of the pedals 34, the rate of decay of the bass tones is slow. If the sustaining pedal is not down when one of the pedals 34 is depressed, the bass tones has a fast decay. Upon release of pedal 34, switches 40, 41 operate to cause rapid decay of the bass tone.

Abstract: 1,127,197. Paraphase amplifiers; phase shifters; demodulators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 5 Sept., 1967 [13 Sept., 1966], No. 40825/66. Heading H3T. A paraphase amplifier comprises a Darling- ton pair of transistors with equal emitter and collector resistances. When an RC or LC circuit is connected across the output of such an amplifier a phase-shift circuit results, and such circuits may be cascaded for greater phaseshift (Fig. 4, not shown). Alternate stages may use transistors of opposite conductivity types with separate H.T. lines (Fig. 5, not shown) or with decoupled Zener diodes in the emitter leads to establish the correct bias conditions. Fig. 6 shows a demodulator for single-sideband signals using stages RC1-RC4 according to the invention. The input ip is applied to two switching-modulators Tr1, Tr2 supplied with carriers C1, C2 in quadrature. The modulator outputs are each applied to two cascaded amplifiers according to the invention, with RC phaseshift circuits, followed by Darlington emitterfellowers DT1, DT2. The outputs of the latter are additively combined via resistors Rs1, Rs2 and the carrier frequency filtered out before final amplification of the demodulated signal by transistor Ta.

In an apparatus for grouping and banding envelopes, groups of envelopes are conveyed by sets of pliable grippers 33, 34 which are mounted articulately on pairs of chains 3, 8 which are driven forward intermittently, each step corresponding to the distance between consecutive grippers 33 on the chains 3, 8. Envelopes are fed in singly by spiral conveyers 1, 1a, 2 and accumulate against stops 71 and 47<SP>11</SP>, 48<SP>11</SP> which move forward to accommodate them. As these moving stops reach the further stops 43, 38, the former are withdrawn from the stream of envelopes and returned to their initial position, Fig. 1, where they are reinserted to divide a group P of envelopes from the incoming stream B. During the return movement of the stops 47<SP>11</SP>, 48<SP>11</SP>, which are in the form of scissors, the chains are advanced one step; the grippers 33, 34 (on the right hand side of Fig. 1) are rising and the two grippers 33 engage with the stops 47<SP>11</SP>, 48<SP>11</SP> and are bent away from their partners 34. Rising further the grippers 33, 34 engage the group P and as the stops 47<SP>11</SP>, 48<SP>11</SP> move in, Figs. 5, 6 (not shown), the grippers are released and spring inwards to grip the group P and convey it forward towards P<SP>1</SP>, the stop 38 being withdrawn by means of cams 41 on the chain and stop 38 by electromagnets 45. Meanwhile, the group of envelopes formerly at P<SP>1</SP> moves towards P<SP>11</SP>, a band 76 being passed around it by arms 94, 95 and held in place, while sealed, by clamp members 89, 76; the group formerly at P<SP>11</SP> moves towards P<SP>111 </SP>where the grippers are withdrawn therefrom. Completed packages at P<SP>111 </SP>are prevented from falling over backwards by a stop 85 which is pivoted away when a package is passing but falls back immediately after under the action of a spring.
