Title: Roll film photographic cameras
IPC: G03B17/02
Filed: 1963-01-22
Abstract: 1,034,045. Roll-film cameras. EASTMAN KODAK CO. Jan.22, 1963 [Jan.22, 1962], No. 2785/63. Heading G2A. In a roll-film camera having latching means for locking the camera shut, winding mechanism which is in engagement with a film winding member is retracted out of engagement therewith when the latching means is unlocked. In the form shown, the camera comprises a front housing 12 and a removable cover 14, held in position by a fixed locking element 16 on cover 14 which latches into a movable locking element 18 on housing 12. Element 18 has an L-shaped slot 22 at its lower end, in which engages a fixed post 20. At its upper end it has a fixed shank 24 which extends through a slot 26 in the housing, so enabling the latch to be manipulated from the outside. In Fig. 2 (not shown) the latch is in the locked position. When shank 24 (and consequently element 18) is pushed upwards, so that the hooked portion of element 18 is drawn clear of the corresponding hooked portion of element 16, element 18 is pulled by an attached spring 28 into the inclined position shown in Fig. 4. The film take-up spool 30 has at its upper end a number of ribs 56, in which fit keyed portions 46 of a driving member 44. This is fixed on the end of a shaft 34 having an external winding knob 38. The keyed member 44 is urged into engagement with spool 30 by a spring 48, but can be drawn out of engagement therewith, against the spring, by pulling knob 38 upwards. This is done when the spool is to be removed. The locking element 18 has an extension 58 which passes through the housing and is located just under knob 38. Thus when element 18 is pushed upwards to release the latch, the same movement pushes knob 38 upwards also to disengage the driving member 44 from the spool. When cover 14 is pressed on to close the camera again, the sloping faces of the two hooked portions of the latch make contact, the lower part of element 18 moves so that post 20 re-enters the vertical part of slot 22, element 18 moves down under the action of spring 28, the hooked parts latch together again, and extension 58 moves away from knob 38, allowing the driving member 44 to engage once more with spool 30. In Fig. 7 (not shown) the centre of the spool is utilised to house a battery for flash operation, and means are provided for preventing the spool from being inserte into the camera if the battery is in the wrong way round.

Title: Improvements in radio direction finders
IPC: G01S1/02
Filed: 1942-03-03
Abstract: 555,834. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. March 3, 1942, No. 2810. Convention date, March 6, 1941. [Class 40 (v)] In a direction-finder of the kind using a continuously rotating directive aerial or search coil, or equivalent modulating system, and a synchronously rotating cathode ray, the latter is deflected radially by the rectified carrier, or intermediate frequency current from which the high-frequency components have not been filtered out, so that the beam traces a "solid" pattern. If desired, the beam may also be deflected by the lowfrequency current, i.e. the rectified highfrequency current with the high-frequency components removed. Such a system is shown in Fig. 1, in which currents from the rotating goniometer 3 and receiver 4 are rectified at 5, part of the output passing direct through commutator 9, and part through a low-pass filter 8 and commutator 9, to the grids of a pair of valves 23, the common output circuit of which is connected to the anode 12 of the cathode ray tube. The "solid" pattern due to the highfrequency components and the usual "line" pattern due to the low-frequency currents, thus produced alternately; give the effect shown in Fig. 4. The output of the valve 23 may alternatively be led to deflecting electrodes of the cathode ray tube.

Title: Process for the treatment of ammoniacal gas liquor and other liquids containing tar acids
IPC: C07C37/86
Filed: 1932-01-30
Abstract: Phenols are recovered from ammoniacal liquor by passing an inert gas through the <PICT:0380699/IV/1> liquor at its boiling-point and at a pressure greater than atmospheric.  Ammoniacal liquor is delivered to a stripping tower 12, by a pump 10 from an ammonia still 3, and is scrubbed therein by a circulated gas.  The latter, enriched with phenol vapours, passes through a pipe 34 to a re-circulating tower 14 before flowing through a superimposed absorption tower 13, the towers 14, 13 containing caustic soda solution to absorb the phenols.  The purified gas re-enters the scrubber 12 for the purpose described. Fresh caustic is added to the tower 13 from a feed tank 37; the partly spent liquor is recirculated in the tower 14 by a pump 48. Suitable temperature and pressure are obtained by discharging steam into the tower 12 through an injector pipe 22 or by heating the liquor before entering the vessel 12 in a pressure vessel 25. A suitable pressure may range from 5 to 75 pounds per square inch. Specification 299,837, [Class 55 (ii), Gas manufacture &c.], is referred to.ALSO:Phenols are recovered from ammoniacal liquor by passing an inert gas through the liquor at its boiling-point and at a pressure greater than atmospheric.

Abstract: 548,420. Electric motor control systems. GENERAL ELECTRIC CO., Ltd., and CROFT, E. H. March 7, 1941, No. 3129. Drawings to Specification. [Class 38 (iii)] Regenerative control.-In order to prevent regenerative braking of a traction motor when the controller is moved backwards from a highspeed position (as in passing a section gap) the controller handle is provided with a subsidary lever pivoted at 13 which when operated at will from the central position trips out the line switches or otherwise prevents the excitation of the shunt winding from being increased during backwards movement of the handle. Instead of a pivoted lever, a press-button on the handle may produce the same result; or the handle as a whole may have a pivotal movement in a plane at right-angles to its normal movement for the same purpose. Alternatively, an auxiliary contact drum may be used for the field control, spring connected to the main drum and dash-pot controlled so that on backwards movement it follows with a delay action which prevents regeneration. In another form, the resistances in the shunt field of the motor are controlled by contactors which have a retarded release so that it is possible to take the controller back to the off position and forwards again before the release takes place.
