Filed: 1943-10-19
Abstract: 573,043. Winches. BRACKETT, J. F. Oct. 19, 1943, No. 17203. [Class 78 (v)] A winch of the kind provided with a brake drum loosely mounted on a main shaft, to which is keyed a spur wheel and a drum and/or gypsy, and having one or more pawls pivoted on the side of the brake drum and co-operating with a ratchet wheel keyed to the main shaft, is characterised by the spur wheel being driven by a gear which is movable info neutral position. The spur wheel 4 on the main shaft 2 is driven from a gear 11 on the shaft 9 either directly or through gears 21, 22, Fig. 2. The gear 11 is shifted from one driving position to the other, or to neutral, by turning a handle 12 which is mounted on a shaft 13 carrying an arm 14. A projection 15 on the arm engages a groove 16 formed in a boss 17 secured to the gear 11. The brake drum 3 carries pawls 8 which engage a ratchet wheel 5. The. drum is engaged by a brake-band 23, one end of which is connected at 24 to a brake-lever 25, and the other end of which is attached to a shaft 26 on which the lever is mounted. A spring 27 connects the upper end of the lever to the casing 1. A stubshaft 28 carries a handle 29 and arms 30, 32. The arm 30 carries a roller 31, which can be brought into engagement with a notch 34 in the brake-lever to slacken the brake if the arm 32 can pass into a groove 35 in the boss 17. The latter movement can take place only when the gear 11 is in neutral.

Title: Improvements in or relating to kinema films and like strips having feed perforations, and to mechanism cooperating with said perforations
IPC: G03B27/16
Filed: 1921-06-23
Abstract: 186,401. Jeapes, W. C., and Debrie, A. L. V. C. June 23,1921. Printing - apparatus.- A kinematograph or like film has one or more of its feed perforations blinded, so that these may displace pins movable in a member such as, for example, the film-feeding member, the pins operating controlling or regulating means, such as means for controlling the intensity of the light when printing the film, or for controlling the speed, or exchanging the records, of a gramophone working in synchronism with the film during exhibition. The controlling or regulating means may include a perforated insulating strip driven by the pins and movable between two opposed series of electrical contacts, each perforation permitting a selected pair of contacts to engage and close one of a series of electric circuits. In the form shown, as applied to the printing of a film, the negative and positive films 10, 11 are fed together past a lamp 12 by a member 15 having the usual up-and-down movement together with movement towards or away from the films. In addition to the fixed film-engaging projections 14 on the member 15, one or more spring film-engaging pins 19 are carried by a member 17 moving vertically with the member 15. At selected points, perforations on the film 10 are blinded, for example by pieces of celluloid 30 stuck on, these perforations being so chosen that they rest during the feed operation opposite the pin 19 and cause the stem 23 thereof to project into the path of, and depress, a lever which causes a rod 29 to lift and actuate a ratchet-and-pawl gear 35, 36 driving a drum 38 over which passes an insulating strip 39 carrying, in addition to feed perforations, a set of perforations adapted to pass between two series of contacts 42, 43 opposed in pairs, the series 43 being actuated by springs 44. The perforations are punched so that, when a perforation is advanced into operative position by the action of the pin 19, a particular pair of contacts engage through the perforation, closing one of a number of parallel circuits 45, having different resistances, in series with the lamp 12, which is thereby illuminated to an intensity appropriate to the section of film about to be printed. The mechanism whereby the pins 19 operate the controlling or regulating means may be mechanical. Specification 116,921 is referred to.

Title: Improvements in or relating to optical pyrometers
IPC: G01J5/52
Filed: 1927-06-29
Abstract: 291,971. Gall, D. C. June 29, 1927. Pyrometers.-In an optical pyrometer of the kind in which the brightness of the central part of a lamp filament is compared with that of the heated body, means are provided whereby only the central part of the filament, which is immune from errors due to changes in temperature of the surroundings, or lag effects in the base of the lamp &c., is used for the purpose of the measurement required for obtaining the temperature scale. When the temperature is obtained from the voltage drop across the filament, a lamp as in Fig. 1 may be used, having leads a for supplying current to the filament and a second pair of leads b to which the voltmeter is connected these leads being connected to the points p on the filament. Where the resistance of the filament is measured by means of a Wheatstone bridge, the lamp may be provided with extra leads f, Fig. 3, connected to a loop of wire having the required dimensions &c. to compensate forthe errors referred to above. The compensating loop and the lamp filament are inserted in adjacent arms of the bridge. The loop may form the whole of one arm of the bridge and may be. shunted by another loop of different material, or it may form only part of the bridge arm, the whole or part of which may be shunted. Further, the compensating loop may be arranged outside the lamp. In another arrangement, Fig. 5, employed in a Wheatstone bridge circuit, a lamp as in Fig. 1 but with only one additional lead b may be used this lead being connected to the galvanometer g and the two parts of the filament being in adjacent arms of the bridge. With this arrangement the errors due to temperatures lag in the leads a and in the lamp base balance each other in the two arms of the bridge. Shunts as above described may also be used in this arrangement.

Title: A process for the preparation of seeds for subsequent magnetic separation
IPC: B03C1/01
Filed: 1956-06-05
Abstract: In preparing for magnetically separating varieties of seed, even though the varieties have substantially the same shell smoothness and hardness, oil is first applied to the seed mixture, the oil having a viscosity of about 8 to 9 DEG  Engler (or about 60 Saybolt universal seconds or about 10 centistokes).  Powder of magnetic material is then mixed with the oiled mixture, more powder adhering to the seed varieties having greater affinities for the oil.  Preferably before the powder is added, water is added to the oiled mixture, the water removing traces of oil remaining on some seeds, moistening certain seeds which have no affinity for the oil.  Seeds which have rough husks and which may be in the mixture are assisted by the water in collecting the magnetic powder.  The mixture including the powder is finally subjected to a magnetic separating process, to separate those seeds having magnetic powder adhering to them from those seeds which have no or substantially no magnetic powder adhering to them.

Title: Improvements in or relating to strip feeding apparatus for advancing a strip past a recording or imprinting position
IPC: B41L47/30
Filed: 1947-07-01
Abstract: 633,512. Feeding webs. STANDARD REGISTER CO. July 1, 1947, No. 17365. Convention date, July 1, 1946. [Class 100 (i)] In a strip-feeding apparatus for advancing a strip past a recording or imprinting position, having a continuously operated driving means, a yielding coupling between the drive and the strip allows the strip to be intermittently arrested during the printing operation, and a resilient device associated with the drive accelerates the advancement of the strip to take up the amount of retardation caused by the arresting action. The strip 2 is advanced by rotary pin wheels 4 mounted on a hollow spindle 5 adjustable circumferentially by a connection 8 relatively to a short extension 5a of the spindle upon which is mounted an arm 11 having a lug 12 engaging in a notch 10 in a driving sector 9. The driving sector is mounted on. a spindle 6 extending through the hollow spindle 5 and is driven at constant speed by pinions 7. A spring 13, anchored on the sector 9 engages the lug 12 to hold it against the forward shoulder of the notch 10 and forms a yielding drive. When the strip is arrested by the printing member 16 the arm 11 is retarded in the notch 10 against pressure of the spring 13. Upon release of the arresting member, the spring 13 restores the lug against the forward shoulder thus accelerating the strip to catch up with the drive. A stop plate 14 on the sector 9 adjusts the peripheral extent of the notch 10 and thereby regulates the differential range of the sector 9 and arm 11 to accommodate different arresting periods. In a modification, to prevent damage to the sheets the printing member 16 carries a spring-pressed plunger engaging a travelling tape passing round a sprocket wheel on the shaft extension 5a and a distant idle sprocket. The tape acts as a sprocket chain and when stopped by the plunger, takes the strain caused by the spring 13 and prevents damage to the record strip.

Title: Control circuit for automating the operation of a film cutter
IPC: G03D15/04
Filed: 1972-04-17
Abstract: 1391476 Film cutting apparatus EASTMAN KODAK CO 17 April 1972 [16 April 1971] 17633/72 Heading B4B A continuous film roll 15 made up of processed orders spliced together is fed to a blade 23 which cuts each order into segments, each segment having the same number of exposed frames 7 (preferably four) and one segment additionally containing the splice frame 31. For a roll in which the splice frames trail their respective orders, a perforation photo-detector 10 produces a pulse for each perforation and a counter circuit 18 produces a signal X after four pulses. Signal X is fed (a) to a release circuit 20 which de-energizes a solenoid 95 whereby a pawl 25 engages the next film perforation and opens a switch 96 to disengage a film drive roller 17 and (b) to a logic circuit 32 which sends pulses to operate the blade circuit 38, to reset the counter circuit 18 and, via a delay 36, to a circuit 34 for restarting the film. The machine continues to chop the film into four frame lengths until a splice is detected by a photodetector 14, whereupon a pulse is fed to counter 18 causing it to ignore the simultaneously received perforation pulse. Film feed is thus continued until the next perforation pulse is produced whereupon circuits 28, 22 cause circuit 18 to emit a signal X which severs a four frame-plus-splice segment. Circuit 18 continues to emit signal X and prevent film feed until the cut segments are removed, whereupon a detector 40 cuts off the signal via circuits 42, 28, 22, 18 to restart the film. If the splice frames lead their respective orders, a switch (78, Fig. 2; not shown) in circuit 18 is changed over whereby a five frame length is cut off each order before the four frame lengths. An extra splice detector may be positioned adjacent the perforation detector so that detection of a gap in a bad splice is not accepted as a perforation.

Title: Wet bulb thermometer
IPC: G01K7/06
Filed: 1975-07-16
Abstract: 1464302 Wet-bulb temperature sensor WIRA 16 July 1975 [24 April 1974] 17842/74 Heading H1K [Also in Division G1] A sensing device for measuring wet-bulb temperatures comprises a block 1 of microporous or "foam" metal and electrical conductors 8, 9 for coupling the device to electrically-operated temperature indicating means, the conductors 8, 9 being coupled to the block 1 in such a way that in operation a potential is produced between the dependent upon the temperature of the block 1. When the block 1, which may be of stainless steel, is wetted its low thermal capacity, high surface area and high capillary attraction for water causes it to follow the wetbulb temperature of the atmosphere in which it is situated. The coupling of the conductors 8, 9 to the block 1 may be via a resistance thermometer or thermistor but in the preferred embodiments a thermocouple junction is employed. The conductors 8, 9 may be joined together to form a junction which is bonded to the block 1, preferably within a bore therein, but as shown one of the conductors 9 is of the same material as the block 1 and is bonded thereto at a location 10 spaced from that at which the thermocouple junction 5 is formed between the block 1 and the other conductor 8 of dissimilar material. In order to obtain a direct measure of the difference between wet-bulb and dry-bulb temperatures one of the conductors 8, 9 may include, spaced from the block 1, a temperature sensor of the same type as that associated with the block 1, connected so that the electrical outputs of the two sensors are in opposition.
