Title: Improvements in or relating to photographic cameras
IPC: G03B1/66
Filed: 1961-07-06
Abstract: 957, 099. Film feed indicators. KODAK Ltd July 6, 1961 [July 11, 1960], No. 24557/61. Headings G2A and G2E. A roll film camera comprises a lock for the camera cover, operable by control means rotatable about an axis between open and locked positions, an indicator coaxial with the control means for indicating the amount of unexposed film left and operable by a member which normally engages the periphery of the film roll, and interconnecting means between the control means and member so that when the control means is moved to its open position it moves said member so that it no longer engages the film. In the embodiment shown, a feeler 7 on a rotatable cam disc 5 is urged by a spring 25 against a film (not shown) on a spool 11 and is connected by a means of a projection 15 to a pointer 18 which moves relative to a scale 22 on the disc 6. The length of film can therefore be indicated. The disc 5 is provided with annular grooves 12 which engage rings on the camera cover 14. A manually rotatable knob 28 is provided with a spindle 27 which passes through apertures 36, 37 in the cover 14 and disc 5 the latter being retained on the shaft by a spring clip 38. Fixed on the camera body 29 is a cylinder 39 in which is mounted a rod 42 biased by a spring 43. The knob 28 has an "open" and "lock" position and is releasably held in either of these positions by a pin 32 on it engaging one of two recesses 34 of a slot 33 on the cover 14. In the "lock" position the spindle 27 enters the cylinder 39 and is latched by means of lugs 25 in it and urges rod 42 against its spring. The cover 14 is thus resiliently held on the camera housing. When the knob is moved to the "open" position a projection 31 on it engages projection 15 and rotates the feeler 7 away from the film spool. Simultaneously the spindle is unlatched from the cylinder 39 and the cover 14 can be moved away from the camera housing.

Title: Improved jet noise suppressor nozzle
Inventor: MORLEY FREDERICK WILLIAM WALTE
IPC: F02K1/40
Filed: 1957-08-07
Abstract: 837,501. Jet-propulsion nozzles. ROLLSROYCE Ltd. July 8, 1958 [Aug. 7, 1957], No. 24822/57. Class 110 (3). In a jet-propulsion nozzle silencer comprising a plurality of individual nozzle members in a spaced arrangement around a central nozzle member, each nozzle member has an internal wall member forming a chamber which is closed at its upstream end and open at its downstream end and through which atmospheric air is caused to flow in a downstream direction, the internal wall member being positioned relatively to the inner wall of the nozzle member so as to provide a longitudinal channel for the hot gases from the jet pipe. The jet-propulsion nozzle 10 comprises a central cylindrical nozzle member 11 supported by external and internal wall members 12, 13. The wall members 12, 13 also support a number of substantially cylindrical nozzle members 14 each containing a wall member 15 forming a chamber 16 open at its downstream end and closed at its upstream end. Apertures 17 allow atmospheric air to pass through the chambers 16. Each wall member 15 is spaced from the internal wall 18 of the nozzle member 14 to provide a longitudinal channel 14a for the flow of gases from the jet pipe. The central cylindrical nozzle member 11 has a number of wall members 19 forming chambers 20 to which air is supplied by apertures 21. A plurality of channels 24 allow the flow of gas from the jet pipe. Jet gases pass through holes (not shown) into the space between the walls 12, 13 so that the wall 13 does not have to withstand high gas loads. In a modification, Fig. 5 (not shown), the chambers 16 and 20 are divided by a wall member into inner and outer compartments and the atmospheric air flows only through the inner compartment. The walls of the outer compartments have a number of pressure balance holes. This arrangement allows the structure to be lightened. In this arrangement, a reinforcing plate is welded to the nozzle members 14 around the apertures 17 and the rear section of each nozzle member is formed separately from and then butt-welded to the forward section. A baffle structure is provided at the junction of the members 11, 14 to ensure that the hot gases are directed positively either into the central nozzle 11 or into one of the members 14.

Abstract: 255,275. Carrier, W. H., and Carrier Engineering Corporation. Oct. 6, 1925. Refrigerating, compression machines and processes for; centrifugal pumps; balancing moving parts; leakage-preventing devices.-A fluid compression system, such as a refrigerating system in which a volatile liquid is vaporized and the vapour compressed and condensed, has a multi-stage compressor 0 with enclosed rotor bearings 13, 14. The enclosures round the bearings have pressure equalizing connections consisting of passages 56, chambers 57, 59 and pipe 58. The casing at the driving end of the compressor supports an oil cup 28 supplied with oil by the pump 33 from the tank 30; oil flows from the cup 28 through the bearing 14 and also through the sealing chambers 22, 38 to the trap 42 and tank 30. The pump also secures a flow of oil through the bearing 13 and sealing chamber 18 at the other end of the shaft. Collars 16, 23 secured to the shaft in the sealing chambers take the axial thrust. The sealing, lubricating and balancing arrangements are similar to those described in Specification 218,201. To purify the refrigerant a rectifier 62 is provided; the lower part of the rectifier is connected to the liquid space of the evaporator A by a pipe 61 and the upper part is connected to the first stage of the compressor. An economizer 69 of the kind described in Specification 220,299, [Class 29, Cooling &c.]. is arranged next to the rectifier, and contains the warm refrigerant from the compressor C and condenser B. The liquid in the purifier is thus heated and the vapour is drawn off by the compressor, while oil and dirt are left in the rectifier.

Abstract: 205,114. Akt.-Ges. Brown, Boveri, et Cie. Oct. 9, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Vapour apparatus, arrangements for; phase, changing.-In order to reduce upper harmonic currents in a vapour rectifier installation comprising a number of rectifiers fed from a common primary net-work, each rectifier or group of rectifiers is fed with currents which are out of phase with the currents feeding the other rectifiers or groups of rectifiers. In one arrangement two rectifiers are fed from six-phase secondary windings on a pair of transformers, the primary windings of one transformer being connected in star, and those of the other transformer in delta, to a three-phase net-work. In the arrangement shown, the rectifiers are divided into two groups with two rectifiers in each group, one group being fed from the six-phase secondary windings S<1>, S<2>, and the other group from the windings S<3>, S<4>. Phase differences of 30‹ are produced in the rectifiers of each group, while the two groups themselves are 15‹ out of phase, the phase differences being obtained by varying the arrangement of the primary windings as shown. The groups of rectifiers may be connected in parallel to a single direct-current net-work, or they may supply separate net-works, which may be at a distance from each other, e.g. in different sub-stations. The polyphase systems for feeding a number of rectifiers may be obtained in a single transformer, and the secondary terminals may be connected to the anodes of the various rectifiers without regard to symmetry in order to simply the wiring.
