Title: Improvements in or relating to photographic processing
IPC: G03D3/13
Filed: 1959-09-03
Abstract: 904,149. Feeding webs. LANGHAM THOMPSON Ltd., J., and PRUDENCE, M. B. Sept. 29, 1960 [Sept. 3, 1959], No. 30092/59. Class 100 (1). [Also in Group XX] In a film or like strip feeding arrangement, the film is inserted through the apparatus in contact with feeding devices in an unlooped condition, and means are provided for rendering the feed devices effective sequentially, and for successively forming loops in the said strip. Fig. 1 represents diagrammatically a number of successive processing tanks, sections 1 and 2 representing a development stage, section 3 a fixing stage, and section 4 a washing stage. The film is advanced through the apparatus by a number of drive sprockets 11-14, and is initially laid across the sprockets as indicated by the line FL1. Between sprockets 11 and 12 is a fixed undriven roller 16. Above each section is a weighted roller 31-34, which is allowed to rest on the top of the film, as shown. First, sprocket 11 only is driven, in consequence of which the weighted rollers 31, 32 descend to form two loops in the film, one on each side of roller 16. The descent is arrested when the rollers have reached a lower position 31<SP>11</SP>, 32<SP>11</SP>, so that the film is now looped down twice into the developing tank. Sprocket 12 is now also set into rotation, so that the film now feeds into section 3. Weighted roller 33 thus can now descend to form another downward loop into the section 3 (fixing) 'tank. Similarly, on causing sprocket 13 to operate, roller 34 forms a loop into the section 4 tank (washing). Sprocket 14 then comes into operation, and the film thereafter feeds at a uniform speed through the apparatus. Sprocket 11 is driven directly from a motor, and this drive is transmitted to the other sprockets by a chain 22. The drive only becomes operative on sprockets 12, 13, 14, however, when a clutch mechanism is actuated. Each sprocket has its own clutch 30, 31, 32, respectively, operated by a solenoid B, C, D. A cam mechanism (Fig. 2, not shown), is arranged to actuate three microswitches in succession, at predetermined time intervals, to bring drive sprockets 12, 13, 14 into a successive operation at the required times. Fig. 3 (not shown), is a suitable circuit for carrying out the sequence of operations automatically.

Abstract: 762,337. Aerial coupling arrangements. KOLSTER-BRANDES, Ltd. Oct. 20, 1954, No. 30159/54. Class 40(7) A circuit arrangement feeding radio frequency signals in differing frequency bands to separate outputs, the higher frequency signals not being switched, comprises a transformer 1 one end of the primary of which is coupled through a capacitor 4 to earth. The capacitor 4 has a tuned circuit connected across it and has a value such that its impedance is small over one of the bands and high over a second. The secondary 7 of the transformer is connected to one outlet from the circuit. The other outlet is connected across capacitor 8 of the tuned circuit, it being possible to include inductor 10 or 11 in circuit at will by means of switch 9 to tune this outlet over a desired range of values. The higher frequency input may be connected across input terminals 5 and 12, or 5 and 6 and the lower frequency input across terminals 5 and 6, or 12 and 6. The circuit may be associated with a dipole aerial and coaxial feeder arrangement in which the feeder outer acts as the receiving element for the lower frequency signals. In such case the feeder inner conductor is attached to terminal 5 and the outer to terminal 12; terminal 6 is, of course, earthed. A more complex embodiment in which a further transformer's primary winding is tuned by a capacitor and connected between winding 2 and capacitor 4 is described with reference to Fig. 2 (not shown). Signals in yet a further frequency band can be derived from the secondary of the second transformer.

Filed: 1925-12-02
Abstract: 257,795. Marks, E. C. R., (Worthington Pump & Machinery Corporation). Dec. 2, 1925. Pistons; cooling.-In a piston-cooling, telescopicpipe system, injury from misalignment or irregularity of movement is avoided by mounting the stationary portion of the system on a flexible or universal joint. The cooling chambers of inner and outer pistons of a double-acting internal - combustion engine are cooled by liquid which passes through the piston-rods and returns by a central pipe. An obstruction in the supply passage causes the cooling-water to circulate around the lower piston. The supply and return passages extend to the crosshead and are connected by passages 13, 14 in a bracket 15 carried thereon to supply and discharge pipes 16, 17 respectively secured to the bracket. The pipes telescope through stuffing- boxes 20 carried by stationary pipes 18, 19 supported by universal joints on the cylinder frame B. The cooling-fluid is supplied through a head 21 on the pipe 18 to an interior pipe 23 provided with a head 3 sliding in the pipe 16. Leakage escapes by a pipe 24. An outlet is provided on the pipe 19. Leakage of cooling-liquid and lubricating-oil is removed by laterally-movable scrapers 29 on the rods 16, 17 and collected in a trough 4. The supply and exhaust passages may be reversed.
