Title: Improvements in or relating to exposure meter
IPC: G01J1/42
Filed: 1953-11-20
Abstract: 749,725. Photo-electric exposure meters. GOSSEN & CO., GES., P. Nov. 20, 1953 [Nov. 24, 1952], No. 32260/53. Class 40 (3). [Also in Group XX] In a photo-electric exposure meter, light intensity values measured by the meter are indicated on a first scale and one part of a transversely divided rotatable roller is provided with light intensity values corresponding to those on the first scale while a second part of the roller is provided with axial rows representing aperture. The two parts of the roller are relatively adjustable to take account of film speed and then locked together so that when the first part of the roller is rotated to a " light " value corresponding to that indicated by the exposure meter the various aperture values in the second part of the roller may be read against corresponding shutter speeds. As shown, Fig. 1, light received through a transparent honeycomb element (not shown) on the top of the meter causes a photo-electric cell (not shown) to position the pointer 5 of a moving coil meter. The scale 7 associated with this pointer is in twelve divisions and twelve corresponding divisions are provided on the edge periphery of the portion 12b of the composite roller shown in Fig. 6. This roller is rotated until the speed, corresponding to that indicated by pointer 5 appears in a window on the front of the instrument. The section 11b of the roller carries a number of parallel axial rows of figures representing aperture settings, one row at a time being visible through a window in the front of the instrument. In use the two sections of the roller are adjusted relatively to each other to take account of film speed by depressing plate 13 on the end of spindle 11a. This releases pins 12a on section 12 of the roller from depressions in the other section 11 allowing them to be rotated relatively to each other until the pins engage other depressions. End plate 13 is calibrated in film speeds which are brought to correspond with a fiduciary mark on knob 12. The roller as a whole is then rotated by knob 12 to bring the light intensity corresponding to that shown by the photo-electric exposure meter to show in window 12b. The various values of aperture may then be read against corresponding shutter speeds 18. The aperture and shutter speed markings may be transposed.

Title: Improvements in bottling machines
IPC: B67C3/24
Filed: 1925-12-22
Abstract: 264,008. Jorgensen, A. M. Dec. 22, 1925. Bottling.-In a rotary bottling machine in which the bottle rests run on rollers around a track having an inclined portion, the machine is automatically stopped if the pressure on a bottle rest becomes abnormal, as, for instance, if a filling tube strikes a bottle lip instead of entering the bottle. The rollers e, Fig. 1, of the bottle rests d run on a track f having an inclined portion g displaceable therefrom against spring action when abnormal pressure is exerted on a bottle rest. As shown, the portion g pivots about an axis m parallel to itself and displaces a rod k connected to a switch for stopping the machine, but the portion g may have one end pivoted to the track f about an axis perpendicular to itself. When spring bottle rests are used, a stationary inclined rail h, Fig. 5, is disposed between the rests and the inclined portion of the track is pivoted to two links i pivoted on stationary vertical axes m. Normally the rail h is held in the inoperative position, with one of the links i abutting against a stop p, by a spring &c. o, but undue pressure moves the rail forwards and effects the stopping of the machine.

Abstract: 603,129. Running generators in parallel. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 30, 1945, No. 32425. Convention date, Dec. 1, 1944. [Class 38 (iv)] [Also in Group XXXVII] In a system wherein parallel generators supply bus-bars 51, 52, a generator 50 is connected to the bus-bars when its voltage exceeds the bus voltage sufficiently to supply some current to the load 53 by means of a reverse current relay, [see Group XXXVII], having a winding 39 of many turns, in series with a resistance 54, and a low-resistance winding 40 of one turn. When the voltage is sufficient, the winding 39 which is alone in circuit operates the relay closing contacts 36, 37 which through a relay 56 puts the winding 40 into circuit and effectively short circuits the winding 39. The generator now supplies the load and this continues till the current reverses, causing a return movement of the relay which restores the original conditions and effectively takes the generator off the bus 51, 52 so far as supplying load is concerned.

Abstract: 508,366. Screw propellers. HAUTIER, C. Nov. 26, 1937, No. 32652. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 27, 1938.] [Class 114] A variable-pitch propeller of the type wherein the boss is free on its shaft and receives its drive therefrom through the pitch-varying gear has each blade root provided with a bevel wheel engaging two facing bevels free on the shaft and clutch mechanism for engaging cither or both shaft bevels with the shaft and there are also abutments for limiting the pitch settings. The blade root 8 has a bevel 10 engaging free bevels 4, 5 having dog clutch faces 4a, 5a respectively. A slidable dog 3 on a sleeve 2 is splined to the driving shaft 1 and when in engagement with either of the bevels, first rotates the blade to a position determined by the last tooth thereon, the bevels being toothed along a portion only of the full circle, and thereafter rotates the propeller. An automatic pitch setting away from the limit position is effected centrifugally by a weighted sleeve 13 concentric with the hub socket 7a and acting through a pin 18 on a slot in the blade root. The sleeve 13 may have additional weights 14 disposed diagonally opposite. In an alternative construction, the bevels 4, 5 have internal helical splines of opposite hand engaging corresponding surfaces a, b on the slidable sleeve 2. The limit positions are set by abutments in hollow slots in the boss sockets which are engaged by a projecting arm on the blade root. A progressive variation in the pitch is obtained as the sleeve is moved until full positive or full negative pitch setting is attained. To facilitate a quick reversal of pitch the boss has a drum 20 which can be - braked. Sliding movement of the sleeve 2 may be effected by pistons 22 in connected cylinders 21 to which pressure fluid may be admitted.

Title: Improvements in or relating to the production of powdery products comprising sodium carboxymethyl cellulose
IPC: C08B11/12
Filed: 1949-12-21
Abstract: A loose fibrous mass comprising a water-soluble sodium carboxymethyl cellulose moistened with an aqueous solution of a water-miscible alcohol, containing water and alcohol in such proportions that the mass will remain in a loose fibrous condition when dried, is converted into a free-flowing powder by directing on to it, while it is being agitated, a dispersed stream of aqueous fluid until the amount of water introduced is at least sufficient to cause incipient gelation at the surface of the individual fibres but insufficient to destroy the loose texture of the mass, then drying and finally disintegrating the dried mass. Air- or pressure-spray apparatus may be used to form and direct a mist of aqueous liquid on to the fibrous mass.  If desired the dispersed stream of aqueous fluid may be a stream of dry steam. The cellulose ether may be obtained by reacting cellulose fibres with sodium hydroxide and sodium chloroacetate in the presence of aqueous alcohol.  The etherification product may contain 60-75 parts of water and 70-85 parts of alcohol for every 125 parts by weight of sodium carboxymethyl cellulose, and it may also contain the by-product salts, mainly sodium chloride.  The surplus caustic soda is converted into carbonate or other neutral or faintly alkaline salt.  The alcoholic strength in the decausticized saline product may be 53-65 per cent based on the sum of the weights of alcohol and water.  The proportion of water sprayed on to the material may be 15-40 parts to every 125 parts by weight of the sodium carboxymethyl cellulose.  When ethyl alcohol is used, the product to be dried may contain alcohol of strength from 40-50 per cent by weight.  Methyl or isopropyl alcohol may be used.  The powdered cellulose ether may readily be mixed with other powders, e.g. detergent powders, foodstuff preparations, flour, sodium sulphate, or sodium carbonate or bicarbonate.  In an example, sulphite wood-pulp chips are mixed with caustic soda ethyl alcohol, and water.  The aged alkali cellulose obtained is mixed with ethyl alcohol and monochloracetic acid.  The mixture is cooled for an hour and then the temperature is allowed to rise to 60 DEG  C.  The reaction product is cooled and then sodium bicarbonate is added to convert the unused caustic soda to carbonate.  A mist of water is sprayed on the product while it is being agitated. The water is dispersed by means of an air-atomizer.  The fibrous product is then dried in thin layers at 60-100 DEG  C.  The dried material is disintegrated in a rotating opposed pin-disc machine or a multi-hammer attrition mill.  In another example, neutralization of the excess of caustic soda is effected by the careful addition of 50 per cent nitric acid.
