Title: A system for determining variations of photographic density of a translucent sheet
IPC: G01N21/86
Filed: 1955-11-22
Abstract: 816,793. Photo-electric testing arrangements. KHOL, F., and SILHANEK, J. Nov. 22, 1955 [Nov. 22, 1954], No. 33415/55. Class 40 (3). Means for determining the optical density of sheet material comprises means for repetitively passing light from a constant intensity source through a sequence of sub-areas of the sheet one at a time, a photo-sensitive device generating electric signals in response to the instantaneous value of the light reaching it through the sheet, and a cathode-ray tube on the screen of which is displayed a curve representing the optical density of the sequence of sub-areas. The sheet material may be a photographic record, for example of an X-ray diffraction pattern. It is wrapped round a hollow transparent or apertured cylinder and light from a steady source 1 is directed on to a small area of it by means of lens 2. Light passing through the sheet is directed by means of lens 6 and mirror 7 (giving a magnification of, e.g., 70 times) out of the end of the cylinder to photo-sensitive cell 8. Immediately in front of the cell is provided an adjustable slot 9 defining the precise area of the sheet being examined having regard to the magnification of the optical system. The cylinder 4 is rotated by a small synchronous motor 5. The output from the photo-cell is fed through an amplifier 10 directly to one side of a changeover switch 12 and also to double differentiating device 11 feeding the other side of switch 12 with impulses at the maximum signal times only. The signals from switch 12 are fed to the vertical deflection system of cathode-ray tube 13 which is provided with a horizontal time-base, synchronized with the rotation of cylinder 4, from unit 14. With the tube connected directly to amplifier 10 a curve is produced on the screen indicating the optical density of the sequence of sub-areas scanned. With switch 12 in the other position a series of marks indicating the points of maximum density is produced. The switch is changed over from one input to the other at a frequency of the order of 25 cycles/sec. so that both displays are visible at the same time.

Title: Improvements in or relating to induction heating methods and apparatus
IPC: H05B6/02
Filed: 1955-11-24
Abstract: 801,546. Induction heating. AMERICAN RADIATOR & STANDARD SANITARY CORPORATION. Nov. 24, 1955 [Feb. 14, 1955], No. 33676/55. Class 39(3) In an induction heater comprising several coil assemblies, each assembly consists of a split metallic sleeve 1, the longitudinal edges of the split being joined by a member 3 to strengthen the sleeve. The member 3 may be of ceramic material, and insulating material such as mica or asbestos 4 is provided between the sleeve and a coil unit 5 which consists of turns of copper insulated from each other by glass tape. The coil turns may be hollow where it is necessary to provide cooling water. The coil assemblies are joined together by spacer members 8 made of a fibrous or other dielectric material and the coil adjacent the end of the heater, where the workpieces enter, has more than one layer of conductor to produce a stronger magnetic field in this area. A tubular insert 11 is of metal, preferably non-magnetic, and its internal diameter is such that the workpieces, e.g. rivets, just pass through without binding. The passage of the workpieces through the insert 11 may be controlled by tilting. Any tendency for workpieces of magnetic material to remain in the discharge end of the insert 11 as a result of their regaining magnetic properties when cooling is avoided by extending the insert beyond the end of the last coil assembly and thus preventing surface cooling of the workpieces. The sleeve 1 may alternatively comprise a ceramic or other refractory member which has circumferential continuity. More than one tubular insert may be provided, Fig. 7 (not shown), and in a further construction, Fig. 8 (not shown), the tubular insert, which may be other than circular in cross section, has a split throughout its length. The apparatus may be energized by 60 cycle alternating current.

Title: Improvements relating to controls for organs and like instruments
IPC: G10B3/10
Filed: 1934-11-27
Abstract: 446,694. Organs &c. JONES, R. R., 10, Sydenham Road, Cotham, Bristol, and HIGNETT, S., 27, Ivy Leigh, Tue Brook, Liverpool. Nov. 27, 1934, No. 34039. [Class 88 (ii)] In an organ or like instrument, a stop-action balanced crescendo pedal mechanically operates a dual multiple switch so as to move the actual stop controls (knobs or keys) in changing the stops. The pedal, Fig. 3, is pivoted at a on the organ frame L and consists of two parts A, B pivoted together at D with springs F controlling the lost motion between them. To bring stops "on" successively, the toe of the pedal is pressed, thus first closing contacts E<1>, E<2>, Fig. 12, by a bar E<5> and carrying current from source J<2> to the conducting portion M<1>, Fig. 8, of a cranked bar. Continued pressure on the toe of the pedal then rotates the pedal as a whole so that a link C connected to the part B turns the crank M<1> which makes contact successively with spring contact fingers O<1> ... O<5> lying in slots of different length in an insulating plate L<2> and connected to the "on" magnets T' of the stop controls. Friction pads act on the link C to retain the back part B of the pedal in a previously adjusted position till resistance of a spring F has been overcome by movement of the part A from its central position of rest. A heel movement of the pedal by similar action energizes through contacts E<3>, E<4>, the portion M<2> of the crank (insulated from the portion M<1> at Z) and closes successively contacts P<5> ... P<1> connected to the "off" magnets T<2> of the stop controls. Where an organ has also push-button controls for bringing on and off different stop combinations, extra contacts under the control of the pedal are provided at the multiple switch to enable the same "on" and "off" stop magnets to be used. If the pedal is " off " and some stops have been put " on " by hand, on closing contacts E<3>, E' by the heel the stops "on" will be put "off," and vice versa, so that by a movement of the part A only, the pedal may be used as a push-button control, which may be duplicated as at W<1>, W<2>, Fig. 12. The normal position of the contacts O<1> . . ., P<1> . . . may be adjustable. If desired, the contacts of the dual switch may be made to move, the live arms M<1>, M2 being fixed. Specifications 15257/15 and 270,838, [both in Class 88 (ii)], are referred to.

Filed: 1932-12-02
Abstract: 410,877. Feeding sheets. WINKLER, A., 30, Seminarstrasse, and DUNNEBIER, M., 46, Engerser Landstrasse, both in Neuwied, Germany. Dec. 2, 1932, No. 34216. Addition to 378,627. [Class 100 (i).] In apparatus for withdrawing single sheets from a pile as described in the parent Specification, compressed air is introduced from the front of the pile between the sheet which is being separated and the rest of the pile. The pile of sheets 1 rests on an inclined support 2, and the lowermost sheet of the pile is separated and withdrawn by means of coacting rollers 15, 5, in the latter of which a suction separator 8 is provided which separates the edge of the sheet and withdraws it into a recess 7 in the roller 5 so that the edge 7<1> of the recess presses the sheet against the spring-pressed roller 15 and the sheet is drawn over a roller 18 at the top of the support 2. The withdrawal of the sheet is facilitated by directing a blast of air from a pipe 19 between the separated sheet and the rest of the pile, and the separated sheet is relieved of the weight of the superposed sheets by means of pile-supporting tongues 22 which are arranged near the front edge of the pile and are moved towards the pile by a camoscillated lever 24 and are raised by means of underlying levers 30 operated from a cam 31 on a shaft geared to the shaft 6 of the roller 5. The withdrawal of the sheet is facilitated by blowing air between the support 2 and the pile from an air chamber 35 in which are a series of openings 37 leading to passages 38 in the support which run in various directions and cross one another. In a modification, Fig. 2, the tongues 22 are dispensed with, and the blast nozzles 19<1> are reciprocated to and from the pile edge by an oscillating lever 42 and are raised and lowered by a lever 30, so that the air nozzles also perform the function of raising the front of the pile.

Abstract: 341,184. Portable turning-apparatus. COVERLEY, R. H., Glenroy, Clarence Road, Derby. Nov. 13, 1929, No. 34679. [Class 83 (iii).] Apparatus for trueing up the friction surfaces on the shoes of internal expanding brakes comprises a drum which replaces the brake drum and is rotatably mounted on the brake axle so as to cause files adjustably carried thereby to act on the shoes when the brakes are slightly applied. The drum b, which has substantially the same diameter as the brake drum, is rotatably mounted by means of ball bearings b<3> on the axle a which carries the rotary portion of the brake and is rotatable by means of a hand-wheel b<2>. Apertures in the circumference of the drum receive file holders d pivoted by bolts d<1> between flanges b<6>, b<7> and b<8> on the drum. The files f are secured in dovetailed recesses in the holders by means of clamps f<1> and screws f<2>. The radial position of the files is adjusted by screws h<2>, Fig. 2, screwing in bushes h<1> in the holders and engaging hardened bearing blocks h let into bosses d<6> on the periphery of the drum, the adjustment being indicated by graduated bevelled collars h<5>, h<4> secured respectively to the screws h<2> and to spring- raised bushes splined to the bushes h<1>. The holders are secured in the adjusted position by bolts d<7> passing through the bosses d<e> and through slotted side flanges d<5> on the holders, the bolts d<1> and d<7> having serrated heads engaging similar recesses in the drum to prevent rotation when the nuts thereon are screwed up. Inspection holes g, g<1> are provided in the drum and file holders respectively. In operation, after removal of the brake drum the drum b is mounted on the axle a and the file holders are adjusted with the aid of the gauging devices h<2>, h4 and then locked. The drum is then rotated whilst the brake shoes c, Fig. 2, are slightly expanded about their pivots c2 by means of the links c<4> and the brake - applying cams c<3>. The latter are mounted on shafts rocked by levers j, k, Fig. 6, connected by links j<1>, k<1> to levers j<2>, k<2> whose upper ends rest against the axle a in the non- braking position. The levers j<2>, k<2> are rocked slightly by means of screws m<4>, n<4> impinging on the axle and attached to the levers by screwed blocks m<3>, n<3>. Pins m<1> pass through the eyes of the levers and the blocks and the latter are prevented from rotating by further pins m<2>. The file holders may be swung on their pivots d<1> completely clear of the drum for inspection of the brake blocks or cleaning &c. of the files, the latter being of the milling type or the type known by the registered Trade Mark Dreadnought. The brake shoes c are covered with friction fabric &c. surfaces c<1>, and the gauging devices h<2> h<4> enable the radial positions of the files to be adjusted according to the elasticity and hardness of the friction surfaces.
