Title: Oven for heating sealed packages
Inventor: REJLER MARTIN GUNNAR
IPC: B65D81/34
Filed: 1967-06-26
Abstract: 1,215,369. Microwave oven. REJLERS INGENJORSBYRA A.B. 25 June, 1968 [26 June, 1967], No. 30302/68. Divided out of 1,194,594. Heading H5H. [Also in Division B8] A microwave oven for heating food &c. in tightly sealed packages 5a, 5b, which packages have at least one wall which will bulge on rise of internal pressure, has at least one device which detects bulging when the package is in a predetermined position and either switches off or reduces the microwave heating supply or supplies cooling air to the package. In the oven shown packages 5a, 5b are placed on a conveyer 3, which consists of two or more parallel spaced narrow bands or cords, and are introduced into the multizone oven by an electromagnetically operated stop 10. The packages 5a, 5b are arrested individually by a stop in heating zone 1 and heated therein either for a set time or until foil cover 50 bulges, the bulge interrupting a beam of light which normally illuminates a photo-cell 6. The photo-cell thus releases the stop and the package moves to the next heating zone where it is tested by further photo-cells for tightness. In the final heating zone 2, the leading package continues its movement until it interrupts the light beam of a photo-cell 7 which actuates a solenoid 9h to raise armatures 9a, 9f and lift the package from the conveyer belt. A pair of spaced temperature sensors 9d, 9e on the armature engage the bottom of the packet and measure the temperature at spaced points. Heating continues until the temperature at both points reaches the desired temperature. A photo-cell 6 interrupts or reduces heating or supplies cooling air by way of nozzle 12 should the packet bulge during this heating stage. When the final temperature is attained solenoid 9h is de-energized and the packet is lowered to belt 3 which conveys it out of the oven. The temperature sensors 9d, 9e may be thermocouples, thermistors, e.g. wires, layers or heat sensitive semi-conductor diodes or transistors. Alternatively a temperature responsive elongated resistive strip may be used in place of the two sensors, its means resistance determining the final temperature. A radiation pyrometer sensitive to infra-red may be used or the packets may have strips of thermo-colour, i.e. portions which change colour at a specified temperature, which are detected by photo-cells. Softenable portions of the packet made, for example of wax may be detected optically, mechanically, or electrically. The bulge detector may be mechanical, pneumatic, or capacitive. A bolometer may be used, the packet either interrupting the radiation beam or an air jet directed to the bolometer. Packets which do not bulge are rejected. Unbulged, or bulged packets may be marked, and the marked packets sensed photo-electrically. Food in unsealed packets may be cooked, a height detector at the oven entrance rendering the bulge detectors inoperative for this procedure.

Title: Improvements in the manufacture of multi-color kinematograph films
IPC: G03C7/20
Filed: 1927-01-28
Abstract: 285,228. Thornton, J. E. Jan. 28, 1927, Drawings to Specification. Colour kinematography.-Positive multicolour films of standard thickness are produced by cementing together in register with a colloid or cellulose cement colour-record components printed on thin film-strips formed of readycoloured sensitized colloid only, without the usual supporting layer of celluloid &c., and protecting the finished film with an outer coating of cellulose. The film material upon which the images are printed may be of the stripping kind described in Specification 285,227, [Class 98 (ii), Photographic processes &c.]. The component imageseries are printed side by side on a multi-width strip of such material, which is not slit to separate the component films for cementing until all the images have been printed and finished thereon. For registration, a single hole is provided in the film at the left-hand side of everv component image. The images may be printed from a multi-width negative film or printing- cliche bearing images in continuous or broken tones. The film may be developed in apparatus as described in Specification 28875/12, [Class 98 (ii), Photographic processes &c.], and is preferably adhesively supported for this purpose on a continuous or endless belt of metal, celluloid, leather-cloth, linoleum, &c. from which it may be finally stripped. When the component films are to be united by a colloid cement the multi-width film is saturated with a cement comprising glue, acetic or sulphuric acid, glycerine, or syrup, ammonium bichromate and water, and dried. The film is then slit to separate the component films, which are superimposed in accurate register and united by heat and pressure in a machine such as that described in Specification 12229/12. It is finally hardened by exposure to light'which tans the colloid owing to the presence of ammonium bichromate. Hardening may alternatively be produced without exposure to light by substituting chrome alum for the bichromate. When the films are to be united by a cellulose cement such as that described in Specification 246,282, a cellulose layer is interposed between the colloid layer and its temporary support during manufacture of the material. The finished components are coated with a cellulose solution which partially penetrates the colloid layer, and dried. A solvent of cellulose is' applied to both faces of each film in the uniting machine and the components are squeezed into adhesive contact. A final protective coating of celluloid in amyl acetate or cellulose acetate in acetylene tetrachloride is applied to both sides of the compound film in a machine provided with air-jets for clearing the registration holes, and the film is then passed through a perforating machine which punches the feed perforations. Specifications 16201/11, [Class 98 (ii), Photographic processes &c.] ; 26786/11, 25084/12, 26828/12, 224,569; and 224,572, [Class 98 (ii), Photographic processes &c.], also are referred to.
