Title: Improvements in or relating to x-ray film packages
IPC: G03C3/00
Filed: 1946-09-17
Abstract: 618,792. X-ray film packages. KODAK, Ltd. Sept. 17, 1946, No. 27885. Convention date, Sept. 21, 1945. Drawings to Specification. [Class 98 (i)] In a film package a sheet of X-ray film is enclosed by an alloy penetrable by X-rays but opaque to visible light, having a melting point sufficiently below that of the emulsion (which may be hardened) to leave the latter unaffected when the alloy is melted. The alloy may have a melting-point between 110‹ and 170‹ F., and may be Lipowitz or Woods' metal. The package may be formed by placing the film emulsion side down in the middle of a sheet of the alloy having three times the length and breadth of the film, folding the sheet so that there is one layer on the emulsion side and several on the other side which absorb secondary radiation, and sealing either with water soluble cement or by heating to weld together the rear layers. The package may also be formed by dipping the film in the molten alloy ; a separate piece of alloy may first be applied to the rear side for absorbing secondary radiation. After exposure through the single layer, the package is dropped into a light-tight container of hot processing solution, when the alloy covering melts and is subsequently recovered.

Title: Improvements in or relating to receiving devices for remote control systems
IPC: G08C19/16
Filed: 1937-10-13
Abstract: 503,795. Electromagnetic switches. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 13, 1937, No. 27905. Convention date, Oct. 15, 1936. [Class 38 (v)] [Also in Group XXXVIII] A switch actuated by the swinging of a resonance device is prevented from operating if the device is swung initially by an impulse strong enough to swing it at once to its maximum amplitude. As shown in Fig. 2, the resonance tongue 2 moves the control member 4 through wire 5, the wire being moved gradually by the small swings of the tongue until member 4 is moved over a dead centre and falls by gravity to effect the control. If the initial swing of the tongue is too big, the wire 5 bends and engages teeth in the edge of the arcuate member 6 which prevent the member 4 effecting the control. In the embodiment of Fig. 4, the tongue 12 carries guides 13 between which wire 14 is suspended. When the tongue commences to move, swings of large amplitude are prevented by the wire 14 which is held by the teeth in plate 15. After four oscillations, however, the wire swings clear of the plate 15 and the tongue swings freely and can move a control member.

To hold a car door in an open position, indicated by arc 37 as opposed to the fully open position of arc 38, a hinge member 10 attached thereto and carrying a serrated roller 25 on an upper flange 21 is swung about a pintle 11, the roller striking in the latter part of its motion the downwardly depending arm 26 of an S-shaped torsion bar 19, Fig. 2 (not shown) affixed to a hinged member 9 attached to the door post. The roller deflects the arm 26 and engages one of its peripheral recesses therewith, a spring washer 24 then holding the roller against any further movement so that the two parts lock and mesh perfectly on the return stroke, a slot 34 in a flange 18 affording lateral support to the arm 26. In a modification, Figs. 4-8 (not shown), two spaced rollers provide for an intermediate hold-open position with limited free movement therebetween, while in Fig. 9 (not shown) the rollers are close together to give a hold-open position nearer the fully open position without any free movement. In Figs. 7-9 the torsion bar is of C-shape. In a final modification opening of the hinge is limited by a hook which engages a fixed portion of the torsion bar. The door in the fully open position is limited against further movement when the arm 15 of member 9 engages a stop plate 35 on the arm of member 10.

Title: Rotary motor having an adjustable maximum speed of rotation
IPC: G04C3/16
Filed: 1972-06-15
Abstract: 1400164 Automatic control of speed: electric timepieces INDUSTRIAS DE RELOJERIA SA 15 June 1972 [15 June 1971] 28127/72 Headings G3R and G3T [Also in Division H2] A speed control arrangement compares the time taken for a motor rotor to move between two fixed positions with the pre-set period of a monostable arrangement triggered when the rotor is at one of the fixed positions. The motor rotor carries at least one permanent magnet 2 which co-operates with pick-up coil 6 to provide, through amplifier 5, a driving pulse in coil 7. Pulses are produced also in coil 3 by magnets 2 and these pulses trigger monostable 4 which emits an output pulse of preset duration which disables amplifier 5 so that no driving pulses can be supplied to coil 7 during this pre-set duration. The motor is thus maintained at a speed corresponding to the duration of the pulse from monostable 4. The motor may be used to drive the hands of a high precision watch.
Patent GB-464403-A (GB)
Title: Process for treating boiler feed-water for preventing salt incrustation of turbine blades
IPC: C02F5/08
Filed: 1935-10-11
Abstract: In order to prevent incrustation on the blades of turbines driven by steam produced therefrom water is so treated that the constituents of the residue remaining on evaporation are such that the whole or the major part of the residue solidifies outside of the working temperature range of the turbine.  The water may be treated, as by the addition of an alkali hydroxide, so that the residue solidifies below the lowest working temperature of the turbine.  Alternatively the water may be treated so that the residue is solid at the highest working temperature.  Thus water containing sodium carbonates and sodium hydroxide is treated with acids or acid salts, for example sulphuric acid or sodium bisulphate.  If an alkaline-reacting residue is desired, boric acid, phosphoric acid, mono- or di-sodium phosphate or phosphorus penta-chloride may be used.  Acids which will bind oxygen, for example sulphurous or phosphorous acid, may also be used. Or acids or salts, such as chromic acid or sodium bichromate, which will diminish corrosion by their passivation effect, may be used.

Title: Improvements in and relating to rotary duplicators
IPC: B41L21/00
Filed: 1967-06-20
Abstract: 1,143,517. Rotary duplicator; sheet delivery. G. RITZERFELD. 20 June, 1967 [28 June, 1966], No. 28293/67. Headings B6C and B6H. A rotary duplicator is provided with means for delivering printed copy sheets to alternative receptacles positioned either on the feeding side of the printing cylinder or on the opposite side to the feeding side. Fig. 1 illustrates a printing cylinder 1 carrying a master sheet 12, which co-operates with a counter-pressure roller 9 for printing copy sheets 2 which are fed from table 3 under moistening means 6 and through guide rollers 4, 5 to the printing station. A cam 13 mounted to rotate with the cylinder 1 presses by means of roller 16 upon a pivoted lever 14; a pin 18 fixed to the lever 14 and guided in the forked lug 37 of an extension plate 17 causes the plate to swivel about its pivot 19. After a sheet 2 has reached the printing line A, then the extension plate 17 is in the position indicated by the dotted lines in Fig. 1, and thus the sheet is guided over the plate 17 and along the upwardly-inclined intercepting plate 21 in the direction B until it reaches the stop 50; the guide plate 17 then returns to its full-line position, where it extends plate 21 under the influence of cam 13, lever 14 and spring 20. The sheet 2 reverses under its own weight over plates 21 and 17 and drops on to conveyer belt 22 which delivers the sheet into forward receptacle 27. Guide rollers 55 carried on levers 53 are adjusted by screws 54 in order to smooth the passage of a sheet on the belt 22 and aid its ejection to the receptacle 27. If it is desired to deliver a copy sheet 2 into the rear receptacle 28, then operating lever 31 is thrown; through linkage 39, 34, 40, 35, 51, 19 and 52, the extension plate 17 swivels on pins 19, 52 against stop 38, so that it lies parallel to and extends the rear receptacle 28; this movement also contrives to bring the forked lug 37 out of range of the pivot pin 18 on lever 14. Simultaneously, the lever 31, through linkage 39, 34, 40, 41, 42, 43, 45, 47, 46, 48, causes the intercepting plate 21 to swivel in direction D about pivot 49 (see also Fig. 3, not shown). Thus a sheet delivered from printing line A falls directly on to extension plate 17 and slides into rear receptacle 28.
