Title: Improved instrument for comparing the relative intensity of radiant energy
IPC: G01J1/16
Filed: 1931-12-31
Abstract: 389,214. Photometric apparatus. GUELKE, R. W., 89, Crescent Road, Crumpsall, Manchester. Dec. 31, 1931, No. 36031. [Class 97 (i).] The intensities of two beams of light are compared by creating electric currents of intensities corresponding to the light intensities of the two beams, these currents being balanced against each other and the resultant current being caused to operate a light-regulating means in the path of one of the beams, the regulating means being operated by the moving system of the current-measuring device. In the form shown, light from a source L falls on a rotary shutter R having alternate reflecting and transparent sectors. The reflected light passes through the material X of which the light-transmitting power is to be measured and the light transmitted by the shutter R passes through a light-regulating device W such as an absorption wedge, both beams being then incident on a single photoelectric cell P. The output from the cell, after amplification, is rectified by a commutator C on the shaft of the rotary shutter R and is supplied to a galvanometer &c. G. the moving system of which carries the wedge W. The wedge is thus automatically adjusted until the intensities of the two beams are equal. Instead of using a commutator, a motor generator may be employed to drive the shutter R, the alternating current from the generator being supplied to the field windings of a dynamometer, the moving coil of which receives the alternating current from the cell P and carries the wedge W. An arrangement using two photoelectric cells in a bridge circuit is also described. Specifications 291,397, [Class 97 (i), Optical systems &c.], and 373,744 are referred to.

Title: Boiler for heating water and generating low-pressure steam
IPC: F24H1/44
Filed: 1930-12-01
Abstract: 357,431. Internally-fired hot-water boilers ; vertical steam boilers. PRINZ, J., 30, Scharnhorststrasse, and BERNDS, D., 89, Schillerstrasse, both in Dinslaken- Niederrhein, Germany. Dec. 1, 1930, No. 36133. [Classes 64 (i), 64 (iii), and 123 (ii).] In a boiler for heating water and generating lowpressure steam, and consisting of a water-jacketed firebox having water-holding chambers extending thereinto, the chambers 4 extend over the entire length and the greater part of the height of the boiler and communicate freely at the top and the rear with water chambers 1, 2. A collecting- chamber 9 for the flue gases is situated entirely in the water chamber 12, and the return water is conducted directly into the hollow firebars 5 communicating with water chambers 2, 3. The chambers 4 may also extend over the entire height of the boiler and the furnace door 17 may be replaced by a water-holding wall connected to the chambers 4 and chambers 1, 3. There are no hollow grate-bars in this construction and water to be heated enters the bottom of the two chambers 3 and is constrained to rise through chambers 4 by a distributing plate which closes the water-holding walls of the firebox for vertical flow. If the boiler is heated by means such as a gas flame the bottom plate of the boiler casing leaves a gap for combustion air. The boiler may also be heated by steam or hot water passing in countercurrent to the water to be heated, in which case the bottom plate is fixed in a watertight manner.

Title: Improvements in or relating to mould adjusting means for glass shaping machines
Filed: 1934-12-18
Abstract: 439,392. Glass manufacture. UNITED GLASS BOTTLE MANUFACTURERS, Ltd., and DORMAN, E. P., 40, Norfolk Street, Strand, London. Dec. 18, 1934, No. 36273. [Class 56] The moulds of a glass-blowing machine are provided with means for adjusting their position on the table or carrier on which they are mounted, the adjusting- devices being operable from the outside or peripheral portion of the machine. Fig. 1 shows a finishing mould 1 made of two parts hinged on a vertical pin 2 supported by a plate 4 on which the mould halves slide. The plate 4 is supported in turn on a part 6 of the machine, and the hinge pin 2 extends downwards through an opening 8 in the part 6, a nut 10 being provided to clamp the hinge pin in position after adjustment. The lower end of the hinge pin is embraced by a fork which forms one arm of a bell-crank lever 14, Fig. 2. The other arm carries a nut which screws on to one end of a spindle 18, and the other end of the spindle screws into a nut 20 carried by the part 6 near the peripheral portion of the machine. The two screws are of opposite hand, and by turning the spindle 18, the bell-crank lever 14 can be swung on its pivot and the hinge pin 2, and the rear part of the mould can be adjusted laterally in one direction or the other on the part 6. The plate 4 is also provided at its outer end with a lug 25 through which a screw 26 is threaded. The ends of the screw bear against a pair of lugs 28, 29 attached to the part 6. Thus by turning the screw 26, the front portion of the mould can be moved in one direction or the other laterally on the part 6. Another screw 34, which is threaded on a lug or projection 32 secured to the outer edge of the part 6, bears against the outer edge of the plate 4. This screw enables the plate 4, and therefore the mould, to be pushed towards the centre of the mould table, the mould naturally tending to move outwards by centrifugal force when the screw 34 is slackened back. The various adjustments are effected from the outer edge of the mould table, and they enable a finishing mould to be brought into accurate register with a neck mould.

Title: Stepping device
IPC: F16H31/00
Filed: 1963-09-19
Abstract: 1,024,020. Intermittent gearing. HOLLYMATIC CORPORATION. Sept. 19, 1963 [Oct. 4, 1962], No. 36900/63. Heading F2Q. In a mechanism for intermittently moving a pivoted plate 57 to actuate a switch 60 controlling a conveyer belt of a patty moulding machine (see Division B5) after selectively predetermined movements of a driving member 50, the driving member is advanced stepwise from a selectively located stop 42 to a position in which a pin 62 thereon deflects the plate 57, the location of the stop determining the number of steps, and is then returned to its initial position. The stop 42, on a member 39, is selectively located by a knob 38 and held in the selected position by a spring ball detent 56 engaging a sprocket 40 formed on the member 39. A spiral spring 68 urges a pin 53 on the member 50 against the stop 42. A fixed pin 44 is engageable by a pin 43 on the member 39 to limit the rotation of the knob 38. A pin 31 steps a sprocket 52 formed on the member 50 one tooth-pitch for each revolution of a continuously driven shaft 25, until the pin 62 reaches a position in which it deflects the spring-loaded plate 57 far enough to actuate the switch 60. The pin 62 is retained by engagement with a recess 64 in the plate 57 until a cam 34 on the shaft 25 further deflects the plate 57 to release it, the spring 68 then returning the initial position, in which the pin 53 contacts the stop 42. During the stepped advance of the member 50, back-running is prevented by engagement of the sprocket 52 by an edge of the plate 57. With the knob 38 in an extreme position, a pin 61 on the member 39 holds the plate 57 in the position holding the switch 60 closed, the cam 34 then passing to one side of the plate 57.

Title: Improvements in or relating to the packaging of materials, particularly perishable foodstuffs
IPC: B65B67/04
Filed: 1938-12-21
Abstract: 522,460. Packing. DEWEY & ALMY, Ltd., (Dewey & Almy Chemical Co.). Dec. 21, 1938, No. 37215. [Class 94 (i)] Relates to a method of packaging materials, particularly perishable foodstuffs which are intended to be preserved subsequently by cold storage or chilling. According to the invention, an envelope or bag of flexible and elastic material impervious to air and moisture is distended to a predetermined size, an article is inserted therein, and the envelope is then caused or permitted to contnact on to the article. The envelope may be of unvulcanized or partly vulcanized rubber, and it may be of cylindrical shape but is formed preferably with an enlarged upper portion 29, Fig. 6. The envelope 3, Fig. 1, is inserted in a cylindrical container 1 and its upper edge is turned over the rim 5 of the container to form an air-tight seal between them. Air is then withdrawn from the chamber through a pipe 6 to cause the envelope to distend into contact with the walls of the chamber, a perforated partition 7 limiting the downward expansion. In order to ensure even stretching of the rubber a plunger'may be provided to press it downwards, but a pin 10 may, be provided for the same purpose. The pin also shapes the envelope when a part of the envelope is to be inserted into the interior of a packed article, as shown in Fig. 3. The stretched rubber is stiffened, to cause the envelope to maintain its shape, by chilling it by means of an air jet, or by circulating cooling fluid through a jacket 27 in the container 1. The article is then inserted in the envelope, the vacuum about the envelope is relieved, the upper end of the envelope is gathered about a nozzle 11, and air is exhausted from within the envelope. Finally, the neck of the' envelope is sealed, and the rubber is subjected to the action of heat to restore its elasticity before the package is put into cold storage.
