Title: Improvements relating to the production of photographic sound records of the varying
IPC: D04C5/02
Filed: 1931-06-04
Abstract: 384,333. Optical sound - recording apparatus. BRITISH ACOUSTIC FILMS, Ltd., 142, Wardour Street, London.-(Assignees of Poulsen, A. ; 7, Hoyrupsalle, Hellerup, and Petersen, A. C. G. ; 183, Norrebrogade, Copenhagen, both in Denmark.) June 4, 1931, No. 16304. Convention date, Dec. 15, 1930. [Class 40 (ii).] A method of preparing a negative sound record of the constant width and variable density type by directing a transversely disposed linear strip of light on to a moving film k comprises varying the mean intensity of the light strip by means of a direct current which influences the sound-recording means and is decreased as the volume of the sound increases. The recording apparatus comprises an oscillograph mirror e, Fig. 4, which is exposed through a rectangular aperture g to a light source i, an image of which is formed in the plane of the mirror by means of a lens n<1>. The mirror projects an oscillating beam of rectangular cross section on to a screen l placed between the mirror and the film k in such a manner that the image g<1> covers a rectangular aperture m in the screen. , A cylindrical lens n produces on the film k a linear image il of the image of the light source formed in the mirror. The mirror is adapted to oscillate in accordance with the sound waves by means of an alternating current supplied through a transformer T, Fig. 6, to the oscillograph loop f and the image g<1> is caused to move across the aperture m by feeding the anode current of a valve v to the oscillograph loop. The grid of the valve v is connected through a resistance. t and condenser u with the anode of a valve s which is controlled through a transformer T<1> by a portion of the sound current. The initial voltage on the grid of the valve v is selected so that a comparatively considerable anode current flows in the valve v when the sound oscillations, and therefore the current rectified by the valve s, are small. The mirror is then arranged so that the upper edge of the image g<1> lies approximately at the bottom edge of the aperture m, and the exposure of the film is then very weak. As the amplitude of the sound increases, the anode current of the valve v decreases and the image g<1> moves across the aperture m. The anode current of the valve v is arranged to be zero when the sound amplitude is at the maximum and the mean density of the film should then not exceed 50 per cent. The Specification as open to inspection under Sect. 91 also describes the following : (1) the positioning of the mirror e so that when at rest the image g<1> is situated either appreciably above or somewhat outside the bottom edge of the aperture m ; and (2) an arrangement wherein the displacement of the image g<1> is effected at the start in proportion to the amplitude of the sound and later with decreasing increments, this control being effected by a suitable selection of the initial grid voltage of the valve v. This subject-matter does not appear in the Specification as accepted.

Abstract: 972,155. Feeding webs. D. W. ARCHIBALD. July 26, 1963 [April 28, 1962; March 26, 1963], Nos. 16309/62 and 11828/63. Heading B6B. Apparatus for folding a web fed from rollers 12 (Fig. 1, Provision 11818/63) into a series of superposed plies comprises a pair of aligned discs 9 having slots 52 in which are supported a series of rollers 12 constrained by a stationary cam 54 to move in an endless path. The web is delivered into a loop 22 between two rollers 14, which loop is carried to the right and flattened as the roller 14 on its left enters a part of its path where it is constrained to alter its direction rapidly upwards. As each roller comes to this part of its path it is caused to move round drive pulleys 28 and at the same time to rotate counter-clockwise, thereby delivering the loop upwards. The loops thus come to lie on each other in an area 10 above the rollers 14, whence it is led off over a take-off roller. Two levers 7 are oscillated in timed relationship to the movement of the rollers, whereby the lower ends 102, Fig. 2, of arms 100 pivoted to the levers move to the right between two rollers to form each new loop, while the upwardly moving roller 14 then acts on plates 110 through links 106 withdraw the ends 102 against spring action. In another form, not shown, the mechanism 7, 100, 110 is omitted and the slots curve towards the disc axes at their inner ends. In another form (drawing accompanying the Complete Specification) the discs are smaller and the rollers at the bottom part of their paths engage the loops, being rotated clockwise geared rings 5 driven by a gear 4a and guided by two more such gears, so as to transfer each loop from left to right. The pulleys 28 and the rollers 14 are also geared. A rod 3 moves the arms 100 to the right when the levers 7 are in their left-hand position to avoid fouling the incoming web. The rollers are supported on part of their paths by supports 54a.

Title: Improvements in continuous rod cigarette making machines
IPC: A24C5/31
Filed: 1931-06-05
Abstract: 372,967. Cigarette-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) June 5, 1931, No. 16498. [Class 130.] To facilitate threading the paper and clearing a jam the rod feeding tape T of a continuous rod cigarette-making machine is driven from a tape wheel by two manually operable mechanisms, one for turning the tape wheel in the forward direction only, and the other in either direction. A hand-wheel 18 carries on its shaft 16 a worm wheel 19 which meshes with a worm wheel 20 and when rotated in a clockwise direction drives a shaft 7 through a one way clutch 22. The shaft 7 drives the tape wheel 3 in the forward direction through worm gearing 6, 5. When the hand-wheel 18 is turned counterclockwise the one way clutch 22 releases the shaft 7 and the shaft 16 through a sprocket 25 and chain 26 drives a sprocket 28 which through a one way clutch including coupling members 31, 33 drives the worm wheel 5 and the tape wheel 3 in the forward direction. When the machine is running, the tape wheel is driven by the shaft 7 and the one way clutches prevents the hand-wheel 18 from rotating. A hand wheel 37, after the coupling members 31, 33 have been disengaged by a hand-wheel 40, turns the tape wheel 3 in either direction through gear wheels 10, 11. To prevent the tape T from slipping on the tape wheel 3, a friction tape F driven from a roller 8 is led partly around the tape wheel.

Title: Improvements in uniting by fusion
IPC: B23K5/06
Filed: 1920-06-18
Abstract: 168,701. Percival, S., (Davis-Bournonville Co.). June 18, 1920. Uniting by fusion.-A machine for closing a seam or the equivalent by fusion uniting has means for feeding the work relatively to the blowpipe at a constant speed, and means for producing a dwell at the commencement of the work and for gradually raising the blowpipe at the end thereof. The blowpipe may be temporarily raised when acting on parts of the joint of relatively low conductivity to avoid burning the metal. Articles a are fed by hand or automatically to a guide 4 and are positioned by an end stop 5 carried by a slide operated by an arm 10 on the shaft of a feedroller under the control of a weight 11. Gapped feed-rolls 36, driven through worm gearing by adjustable friction gearing 44, have their operative peripheries formed by adjustable segments 33, 34, and the stop 5 advances the work to be forwarded by the segments 33 to position the front of the joint under the blowpipe flame. The gap 35 causes a dwell sufficient for the initial heating, and the feed is continued by the segments 34 until rolls 39 engage the work and feed it completely through the machine. Cover strips 17 prevent the work from rising during the uniting. One of each pair of feed-rolls is mounted on a spring-pressed slide, the drive being through a pin and arm clutch to permit this motion. A cam 30 on the feed-roll shaft carrying the arm 10 has depressions 70 that act through a bell-crank 28 linked to an arm 23 carrying the blowpipe to raise the flame slightly while uniting in the vicinity of the holes c. A deeper depression 71 raises the flame with an accelerating motion as the end of the joint is reached. The blowpipe is attached to the arm 23 by a sleeve in which it is longitudinally adjustable.

Abstract: 544,941. Electromagnetic clutches without frictional contact. ENGLISH ELECTRIC CO., Ltd., and CARNEGIE, H. S. Oct. 29, 1940, No. 16678/41. Divided out of 544,925. [Class 35] The excitation of the field element of an electromagnetic clutch 4 is prevented from reduction by re-action from the secondary system thereof. In a coupling having a high resistance polyphase secondary winding a bucking exciter 7 may be connected in series with the main source of excitation and driven by the secondary element of the coupling 4 so that increase in slip speed results in a nett increase in exciting current. A de-compounding winding 7b may be associated with a normal field winding 7a and excited in proportion to the current in the secondary circuit through current transformers 10 and rectifier 8 so that the field and flux of the coupling may even increase with slip and produce a load-speed characteristic approximating a rectangular hyperbole such as is requisite for the transmission of constant horse-power. The exciter 7 may be independently driven at constant speed. It may be arranged as a boosting exciter.

The bolt mechanism of the parent specification is modified in that the block 22 is made of a resiliently deformable material and has an underneath surface 34, 34 attachable to a flat surface of an openable member 33 or to a stationary structure 39 of a configuration such that when the block is placed in abutment with the flat surface, it will only touch the latter either at an intermediate portion in the length of the block or adjacent end portions thereof, the underneath portion or portions of the block being spaced from the flat surface whereby when the block is secured to the surface the underneath surface of the block will tend to be deformed thereby causing the surface on which the bolt 23 slides to be deformed to an arcuate shape and hence impede the sliding movement of the bolt along the block. As shown, a single strip 40 comprising a deformable metal strip is inserted in the groove of the bolt 23 such that in the retracted position of the bolt, the stop engages the end face 38 of the block 22, and in the shot position of the bolt, engages the end face 41 of the block 21. The block 21, which may be made of the same material as that of the block 22, may be secured to a rebate in the structure 39.

Abstract: 881,370. Telephone transmission systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 22, 1959 [May 23, 1958], No. 16685 /58. Class 40 (4). [Also in Group XL (c)] Dialling impulses (D.C.) and low-frequency ringing current (17 c.p.s.) are converted into alternating current signals (8200 c.p.s.) by means of a magnetic modulator (see Group XL (c)). The impulsing circuit is connected to terminals 14, 15 ; the ringing current is rectified and applied to 16, 17 ; and the 8200 c.p.s. source is cormected to 10, 11. Normally the impedances of the controlled windings 2A, 2B are high and no output is obtained at 12, 13. However, for the duration of each impulse, and while ringing current is being received the direct current flowing in the controlling windings 1A(I), 1B(I) and 1A(II), 1B(II) respectively, lowers the impedances of 2A and 2B, and 8200 c.p.s. signals appear at 12, 13. In a modification, the ringing current is applied directly to 16, 17 so that a burst of output appears once per half-cycle of the ringing current.
