Title: Automatic temperature regulating system
IPC: G05D23/275
Filed: 1939-03-14
Abstract: 526,378. Automatic control systems. ARMSTRONG HEAT CONTROL CO., and ARMSTRONG, C. E. March 14, 1939, No. 8207. [Class 38 (iv)] Temperature.-To prevent overshooting of the controlled temperature, a room thermostat is associated with a thermostat subject to the temperature of the heating element. A room thermostat 12 has two contact blades 14, 15 cooperating with spaced contacts 17, 19 both connected in a circuit causing a stoker motor, oil bearer, steam valve; &c. to function to provide heat to a radiator near which a thermostat A is installed. The thermostat A has two contacts 3, 4 connected respectively with the contacts 14, 15 and engaged by the temperature sensitive contact 5 when the radiator temperature is low and high respectively. A stop 15A limits the motion of the thermostat 12. The arrangement is such that when room and radiator call for.heat the control circuit is closed over contacts 3, 14 until the radiator is satisfied whereupon heat is not supplied again unless the room temperature is low or the radiator cools if the room temperature is high heat cannot be supplied. If the apparatus requires a second energizing circuit to cut the heat additional contacts 16, 18 on the room thermostat are connected to such circuit. In a modification, Fig. 3 (not shown), two room thermostats, subject for example to temperatures near wall and window respectively, are connected to the respective contacts of the radiator thermostat and operate each on a pair of contacts in parallel in their respective circuits. A further modification, Fig. 4 (not shown), employs a two-way snap-action tilting mercury switch on the radiator thermostat and two mercury switches tilted by the room thermostat, one operating in advance of the other. Fig. 2 shows an arrangement for the control of a succession of steam valves 7 by which heat supply to the radiator is graduated according to outside temperature by a thermostat 46 when the radiator thermostat 31 is on its contact 33 and the room temperature is at a desired value (contact 42). In this arrangement the lead 52 causes closure of all valves and leads 53 ... 56 the opening of valves in succession till all are open. This figure also shows a contact 64 associated with contacts 62, 63 and a time switch contact 29 whereby a lowered temperature may be maintained at night.

Abstract: 374,897. Sorting fruit, vegetables, &c. STODDART, J., 23, Alexandra Drive, Surbiton, Surrey. March 17, 1931, No. 8218. [Class 117.] Apparatus for grading fruit, vegetables, &c., comprises a series of adjacent rotary rollers 1 formed with helical grooves 6, preferably increasing in cross-sectional dimensions, disposed so as to form a series of substantially circular apertures which simultaneously convey the articles from the feed end to the discharge end of the apparatus and grade them according to size. The helical grooves may be of the same hand in all the rollers which are then driven in the same directions, or of opposite hand in the alternate oppositely driven rollers. The articles are fed from a tray 4, the oversize articles being discharged into a tray 7 and the intermediate grades collected in receptacles 17 under the rollers. A suction device may be used by the attendant for removing small or faulty articles as they travel along the apparatus.

Title: Improvements in or relating to apparatus for the treatment of photographic films
IPC: G03D3/13
Filed: 1927-03-31
Abstract: 278,259. Kodak, Ltd., (Eastman Kodak Co.). March 31, 1927. Continuous apparatus for developing &c.- Apparatus for subjecting strip photographic films to a reversal process of the kind described in Specification 176,357 comprises a series of tanks for the development and treatment of a latent negative image, means for subjecting the film so treated to a controllable printing light, a second series of tanks for the development and treatment of the latent positive image thus produced, and mechanism for driving the film continuously through the first series of tanks, past the source of printing light and then through the second series of tanks. The film 2 is drawn from a spool 1 past a table 40 at which the ends of successive films can be joined together, thence through a reserve supply device B to a tank C where the negative film is developed and treated. From the tank C the film passes through a moistening dish 8, past an inspection aperture 6 and a printing window 7 and then through a tank E for developing and treating the positive image. From the tank E the film passes through a number of squeegee rollers F to a drying cabinet G and thence through another reserve supply device H to an inspecting station comprising a projector 12 and a reel 13 on which the film is wound. The device B is provided with a number of film engaging rollers at its upper ends, and with rollers 51 on a weighted frame 50 within it. When the film is held at the table 40 for joining, the frame 50 moves upwards to permit continuous movement of the film through the treatment apparatus. The tank C comprises a number of tubes 4 through which the film passes successively, these tubes being disposed in a container 5 and being provided with an inlet or outlet 54 at the top and bottom so that all the tubes in one group can be connected by tubing 55. The overflow from the washing tubes runs into the container 5 to maintain all the tanks at a constant temperature. The inspection aperture 6 is illuminated by a lamp 155, Fig. 4, in conjunction with a non-acting screen 57 and reflectors 58, 60. The printing window is illuminated by a lamp 66, Fig. 6, provided with a diffusing screen 68 and an iris diaphragm 69, the latter being adjusted by the operator according to his estimate of the printing value of the film as seen through the aperture 6. The units E, H are similar to C and B respectively. The sprockets for feeding the film through the apparatus are all driven from a single motor 14. The projector 12 has an intermittent feed device driven by a separate motor which advances the film through the projector at a speed considerably greater than that at which it is fed through the treatment tanks. The circuit of this motor is automatically controlled by the rise and fall of the weighted frame within the device H, being closed when the frame reaches the lower limit of its travel and broken when the upper limit is reached.
