Title: Improvements in poultry feeding devices
IPC: A01K31/17
Filed: 1948-12-15
Abstract: 656,534. Automatic devices for feeding animals; poultry houses. SHARPLES, A., and SHARPLES, K. Dec. 15, 1948, No. 32516. [Class 5(ii)] A battery cage comprises three tiers, each consisting of two rows of cages 1, 2, 3, 4, 5, 6, placed back-to-back, food troughs 50 being rendered accessible to the poultry at predetermined intervals by automatically operated mechanism which comprises a movably-mounted water tank and means for causing the level of the water to rise and fall alternately to operate the mechanism. The cages are assembled in a framework of angle members, adjacent rows being separated by sheet metal partitions 17. The wire mesh floors 20 are inclined so that eggs deposited thereon roll into lips 21 outside the cages. The inner ends of the floors are hooked over a longitudinal rod 22, while the outer ends rest ori channel members 23. Grills 31 closing the fronts of the cages are hooked at 32 and prevented from outward movement by rods 33. Endless belts 40 beneath the mesh floors pass over rollers 41. By operating a handle 43 the belt is carried past a scraper 44, which removes droppings. The troughs 50 are pivotally supported on brackets 52 mounted on the ends of the battery. Mounted on top of the battery is a rocking arm 60 carrying at one end a water tank 62 and connected at the other end by a pin-and-slot connection with a vertical rod 63 slidable in supports 64 and connected with arms 65 mounted on the troughs. Adjustable stops 66 67 limit the movement of the rod 63. The rod directly operates the troughs on one side of the battery through the arms 65, the troughs on the other side being operated through connecting 'rods 68, between cranks 69, 70. The tank 62 is filled from a header tank through a supply pipe controlled by a valve 82. When the water in the tank exceeds a predetermined level, the tank rocks the arm 60 to move the rod 63 upwardly and hence bring the troughs into the feeding position. The water in the tank then escapes through a syphon outlet 81 with a control valve 83 and when the water level has fallen sufficiently the arm 60 is restored to its former position together with the troughs. An adjustable counterweight 84 helps to restore the arm 60 to the non-feeding position. The water from the tank is lead to drinking troughs. The troughs may be of rectangular or circular section. In place of pivoted troughs, fixed troughs with pivoted covers may be used. The pivoted troughs may be mounted in a longitudinal opening in a partition separating stock in a poultry house from a gangway where the troughs may be replenished.

Title: Electric time controlling system of shutter
Inventor: ONO SHIGEO
IPC: G03B43/00
Filed: 1968-07-08
Abstract: 1,212,590. Photo-electrically controlled shutters. NIPPON KOGAKU K.K. July 8, 1968, No.32563/68. Heading G2A. [Also in Division G1] The time delay before closing a shutter is obtained by charging a condenser with a current which varies with the illumination of a photo-resistor, but which is held at a predetermined value irrespective of the change in voltage appearing across the capacitor during charging thereof. A timing capacitor 5 is connected in the collector circuit of transistor TR1, the emitter voltage of which is controlled by transistors TR6 and TR7, a change in the divided voltages of resistor 16, e.g. in interlocked relation with the camera diaphragm adjuster and film sensitivity setting, producing a change in the collector current. The base voltage V s  of TR1, proportional to the base voltage V D  of field effect transistor TR5 which itself is proportional to log B where B is the scene brightness sensed by photo-resistor 3, is inversely transformed by TR1 into a collector current which is proportional arithmetically to B. The operating region of TR1 is chosen within such a range that its collector current is not affected by changes of its collector/emitter voltage. When the voltage on capacitor 5 has reached a predetermined value TR3 conducts and TR4 is switched off to deenergize electromagnet 7 and to thus allow the shutter to close. By the use of field effect transistor having an input impedance of the gate circuit of almost infinity, the value of V D  at the instant of shutter operation can be stored on a capacitor 11, a switch 14 being opened e.g. by the mirror moving mechanism of a reflex camera. A diode 19 and thermistor 10 is included in the circuit to effect temperature compensation. The exposure time of the shutter may be determined in advance by connecting a voltage indicator between the bases of TR1 and TR6. Photo-resistor 3 may be replaced by a manually variable resistor.

Title: Improvements in or relating to the manufacture of centrifugal castings
IPC: B22D13/10
Filed: 1938-11-11
Abstract: 521,279. Casting-machines lining moulds. DEUTSCHE EISENWERKE AKT.-GES. Nov. 11, 1938,'No. 32818. Convention date, Nov. 20, 1937. [Class 83 (i)] [Also in Group V] Mould materials; moulds.-In casting, for instance pipes of iron or steel or non-metals in a centrifugal mould lined with granular material, distributed centrifugally, the material is in a loose and preferably dry condition and the speed of rotation is sufficiently, high, during casting, to resist disturbance of said material by the inflowing metal. The speed may be reduced when the metal begins to solidify. The layer is preferably between 1 to 20 mm. thick and is varied as regards grain size, or thickness, or by using materials having different conductivity or density, or by preheating to give the desired rate of cooling and surface formation. The grains are not less than 0.1 mm. though preferably less than 2 mm. in size and are preferably as spherical as possible. Materials adapted to refine the outer zone of the casting, increase its resistance to corrosion, or form thereon an enamel-like coating may be applied to or embedded in the lining. To avoid the lining slipping at projecting parts of the mould, e.g. at the socket end, pins &c. may be arranged there or the loose sand may be replaced at these parts by a sleeve of dried oil-sand or chamotte. Granular sand, coal, slag, metal, or other material is applied by a tilting trough with inserted filling pieces, if necessary, so that the amount supplied at each point axially is such as to produce the same thickness of powder at all parts of the mould. A cast-iron casing, subdivided axially and radially, having a natural or grooved inner face for venting and an inserted ring of metal, chamotte, or dried sand at its upper end, of the same diameter internally as the desired lining, may be slipped over a split tube, containing silver sand, which is tilted while the casing is rotating. The lined casing has its speed increased, and its axis inclined and the metal is poured in, commencing at the upper end. Impurities are discharged from the mould at its lower end.

Title: Improvements in or relating to daylight-loading processing apparatus for photographic roll film
IPC: G03D13/06
Filed: 1948-12-22
Abstract: 652,729. Photographic developing apparatus. KODAK, Ltd. Dec. 22, 1948, No. 33053. Convention date, Dec. 30, 1947. [Class 98 (ii)] A daylight-loading processing apparatus for photographic roll-film comprises an elongated tank having a light-tight cover and divided by means of a longitudinally extending partition into a narrow chamber and a relatively wider chamber, said chambers being closed at one end and open at the other end of the tank adjacent to means for mounting a film spool so that, during rotation of the latter to unwind a film strip carried thereon by winding means extending through the cover, the leading end of the film strip, which has previously been placed in the narrow chamber, abuts the closed end of the narrow chamber and a loop is formed in the relatively wider chamber. The apparatus shown comprises a tank 10 having an integral partition 20 which divides the tank into chambers 21, 22 of unequal widths. These chambers are open at the end of the tank adjacent to a film spool 18 which is carried by a stud 17 on the tank bottom and is engageable at 29 by a hollow spindle 28 which is rotatable in a light-tight cover 11 for the tank. Spindle 28 has secured thereto a winding knob 30 and a washer 41 prevents axial movement of the spindle. A washer 48 is mounted on the spindle for rotation therewith and freely mounted on the spindle but held fixed to the cover 11 by a lug 37 is a washer 35. Between this washer 35 and the washer 48 three washers are freely mounted on the spindle and, like washer 48, are provided with downwardly extending lugs 38. Rotation of knob 30 thus continues until the lug 38 on the bottom washer is brought into engagement with the lug 37 on washer 35. Such rotation is arranged to be sufficient to unwind the required length of film. In use, a short length of the leader end of the film is unwound from its spool and the latter is inserted into the tank so that the bearing stud 17 is received in the opening in the spool and the unwound film length is disposed in the narrow chamber 21. The cover is placed on the tank and the spindle 28 engaged with the spool. Thereafter, the spindle is rotated counterclockwise so that the leading end of the film abuts against the closed end of chamber 21 and a loop is formed in chamber 22. Processing fluid may now be poured into the knob 30 and will flow through an aperture 34 in the spindle into the tank, a baffle 32 being provided to maintain the tank light-tight. A further lighttight opening 43 is also provided in the cover 11 for admission of washing water or processing fluid.
