Title: Improvements in and relating to flushing apparatus
Inventor: CALLAGHAN JOHN
IPC: E03D1/14
Filed: 1960-12-06
Abstract: 1,037,971. Siphon-discharged water-waste preventers. WILLIAM ROSS & SONS Ltd. July 6, 1962 [Dec. 6, 1960], No. 41925/60. Heading E1C Flushing apparatus of the valveless siphon type comprises in a duct 7 thereof a chamber 12 within which is an obturator 13 which, in a first position, covers a first aperture 16 or apertures therein, one aperture or apertures 23 also being in the walls thereof, and is moved by a piston 9 into that position, the aperture 16 or apertures communicating with the duct 7 and the aperture or apertures 23 with the interior of the cistern outside the duct 7. A spherical member 17 on the obturator 19 is engageable with the aperture 16 to cover it. The latter has a crosssection of less size than that of the apertures 23. The obturator 13 is moved by a lever arm 11 on a rotatable shaft 24 journalled in the cistern wall with one end outside it and having a handle 26, a stud projecting from the shaft 24 intended to contact a fixed abutment to restrict its turning. The lever arm 11 raises the piston 9 in the leg 7 for siphonage a second fixed abutment being contacted by the stud when the shaft is turned and moved axially from a position in line with the first abutment to one in line with the second abutment. The angle through which the shaft is turned is then greater than in the former condition when the obturator 13 does not act to cover the aperture 16. The stud may be located within a slot system in a fixed member incorporating the two abutments. In one system on release after turning the handle 26 returns under gravity to the inoperative position, whereas in the other a spring tends to urge the shaft 24 to that position.

Title: Tape control device
IPC: G11B15/10
Filed: 1970-09-02
Abstract: 1294572 Magnetic tape recorder control circuits LANIER ELECTRONIC LABORATORY Inc 2 Sept 1970 [2 Sept 1969] 41964/70 Heading G5R A control device 10 for a tape recording/ transcribing machine 11 is arranged such that pressing a switch 28 in the circuit from the forward terminal 20 causes the tape (not shown) to be wound on, but releasing the switch causes the tape to be automatically, wound back an amount which is predetermined by the setting of a resistor R 3 . Whilst switch 28 is closed, capacitor C is held discharged, but upon the switch being released, the short is removed and the capacitor charges over resistor R2, R3 thereby switching on transistor T1, T2 to complete an auxiliary path VV from the reverse terminal 21 to the common point 15. Resistor R3 controls the charging time of the capacitor and hence the interval before the transistors are cut off, thereby opening the circuit VV to terminate the run-back. Normal reverse operation is effected by changeover switch 20 which completes circuit V. A "work available" signal from a terminal 18 may be visually displayed by a lamp 23 and an audio signal may be taken from a jack 22. The switches 28, 29 may be footoperated.

Title: Method and means for loading film cartridges
IPC: G03C3/00
Filed: 1969-08-25
Abstract: 1283214 Loading cassettes with film M J ROOS (Kahle Eng Co) 25 Aug 1969 42318/69 Heading G2A A machine is described for automatically winding strips of photographic film and backing paper into a roll, and then loading the roll into a cartridge. As shown in Fig. 1A, the machine generally comprises two rotatable turrets 2, 3 mounted in a cabinet 33. The winding is carried out at the various stations I-VIII on turret 2, and the loading at the various station A-H on turret 3. The upper series of drawings in Fig. 1 show the eight steps in the winding sequence which are carried out respectively at the eight stations of turret 2. At station I a slotted arbor 7 is moved into its winding position by an insertion means 11. At station II the arbor is rotated so as to align its slot in position to receive the end of the backing paper strip 8. At station III the arbor is aligned with a support plate 280 which carries the paper feed system. A predetermined length of paper is unwound from a supply roll, cut off, and fed along a guide track so that its leading end enters the slot in arbor 7. At station IV a photo-electric sensing device checks the presence of the paper strip, i.e. that there has been no failure of the feed mechanism. At station V the arbor is now brought opposite a support plate 300 which carries the film feed system. A predetermined length of film is unwound from a supply roll, cut off, and fed along a guide track to engage in the arbor 7. At the same time a short length of pressure sensitive tape is attached to the upper end of the cut film. At station VI the arbor 7 is rotated so that the film and paper strips are wound together into a tight roll. At the end of this winding step the tab of pressure sensitive tape is forced against the paper, so that the ends of the paper and film strips are joined together. At station VII the arbor is removed from the roll, and at station VIII the roll is transferred across from turret 2 to turret 3. The lower series of drawings in Fig. 1 show the eight steps in the cartridge-loading sequence which are carried out respectively at the eight stations of turret 3. At station A a cartridge casing 12 is transferred from a conveyer 14 to a cradle 15 on the turret. At station B the cartridge is opened by lifting the cover 16 away. Station C corresponds to station VIII of turret 2, the roll being transferred from station VIII of turret 2 to the cradle 15 of turret 3 at station C. At station D a tab end portion 17 of the roll is positioned vertically, in preparation for the next step at station E. Here the spool 13 is lifted out of the cartridge, the tab 17 secured to it by a piece of tape 18, and then returned into the cartridge. At station F the cover 16 is replaced, and at station G the cover is sealed to the body of the cartridge case by an ultrasonic heating process. At station H the completed cartridge is unloaded and discharged down a chute 235. The mechanism at each station on turret 2 and turret 3 for carrying out the particular operation at that station is described in detail.

Abstract: 1400243 Transferring articles between belt conveyers T HAYASHI 14 Sept 1972 [14 Sept 1971] 42768/72 Heading B8A Eight articles are pushed as a group by a pusher 5 on to a plate 7 from a belt conveyer 4. The plate 7 is then withdrawn under a stop 8 which sweeps the row of 8 articles on to a broad conveyer belt 9. The articles are brought into a desired spacing on the belt 4 by the action of an upwardly and downwardly reciprocating roller 11. The latter is operated by a cam 15 driven by chain gearing from a drive motor 55. This gearing also drives the belt 4. A contact 71 driven by the motor 55 closes a circuit to a clutch 67 once for each 8 reciprocations of the roller 11. The gearing is such, that in this time interval the belt moves a distance P. The clutch when energized in this manner operates a drive shaft 24 of the pusher 5 and also steps on the conveyer belt 9. The shaft 24 carries a rotating contact 33 which de-energizes the clutch 67 after one operation of the pusher 5.

Filed: 1969-08-29
Abstract: 1,221,900. Stopping elements at definite positions; positive detents. SIEMENS A.G. 29 Aug., 1969 [30 Aug., 1968], No. 43033/69. Heading F2E. An element (not shown) is driven from the shaft of a gear-wheel 3, coupled by a toothed belt 1 to a driving gear-wheel 2; in the region of the teeth of the toothed belt a toothed stop element is provided, and clamping means are provided to cause a form-locking connection between the teeth of the stop element and the teeth of the belt. The drive must of course be halted when such indexing is effected. In Fig. 1, when the belt 1 is moving, a counterpressure plate 5 forming the free end of a magnet armature 8 is held away from the belt by an electromagnet 6. When the element driven from the shaft of gear-wheel 3 reaches a desired position, electromagnet 6 is de-energized, whereupon a tension spring 7 pulls the plate 5 into contact with belt 1 so that the teeth of the belt engage a toothed stop element 4. In Fig. 2 the toothed stop element 9 is provided on the armature 10 and co-operates with a fixed counter-pressure element 13a. To assist stopping at predetermined positions the toothing of the belt may have part widths of the tooth gaps selectively filled in between the teeth, or part widths of the teeth may be selectively removed between the tooth gaps, or both, the toothed stop element being correspondingly designed. To vary the predetermined positions the teeth on the toothed stop element may be formed by selectively-displaceable pins.

Title: Cutting height control for combine harvester
IPC: A01D41/14
Filed: 1974-10-04
Abstract: 1481083 Controlling combine harvesters MASCHINENFABRIK FAHR AG 4 Oct 1974 [5 Oct 1973 17 Oct 19731 43152/74 Addition to 1396078 Heading A1F The, or each, preferably hydraulic jack which raises or lowers the pivoted cutting platform of a combine harvester is actuated in response to movement of at least one resiliently bendable ear raiser rigidly fixed at one end to the cutting platform and engaging near its other end the ground. The bending of the, or each, ear raiser in response to ground irregularities is converted either; (a) by a senser to an electric signal directly controlling the jack or jacks without amplification, or (b) into an electric signal by a magnetically-operating senser the electric signal controlling the jack or jacks directly or indirectly. Each ear raiser 7 is attached to the cutting platform at 18 and is provided with a stop 20 which is rivetted thereto. Welded to the stop 20 is an angleplate 27. A limit scanner 28 which acts as a changeover switch, is secured interchangeably by two screws to the angleplate 27, the switch plunger 29 resting against a screw 30 the position of which, relative to a deflector 31, is adjustable by a lock nut 32. The deflector 31 can abut the angleplate 27 subsequent to a predetermined bending of the ear raiser, thereby preventing damage to the limit scanner 28. A lifting bar 19 is carried by the forward end of each ear raiser and is provided with a safety bar 35 which contacts the stop 20 should the bar 19 be pressed down by wet harvest material &c. As the ear raiser 7 bends due to ground surface irregularities the screw 30 moves relative to the plunger 29 thereby issuing 'raise' or 'lower' commands, as appropriate, to the cutting platform adjustment system. The command is given directly to a corresponding valve in the hydraulic system of the harvester and does not pass through any electronic amplification system. Preferably a 3-point limit scanner is used wherein, when the harvester is travelling on flat ground the 'neutral' position is set on the valve. The embodiments of Figures 2a and 2b, 3a and 3b and 4a and 4b (not shown) illustrate other arrangements of a limit scanner 28 with respect to the ear raisers 7. A contact-free switching system may be used to convert the bending of the ear raisers to an electric signal. In the embodiment of Figure 5 an inductive pick-up comprises a coil 30a rigidly fixed to a finger 21 and hence the cutting platform and a sensing pin 31a which clips into the coil and is held in contact with the ear raiser 7. In the embodiment of Figure 6 (not shown) a magnetic switch is rigidly fixed to the finger 21 and an actuating magnet therefor is secured to the ear raiser. In a further embodiment (Fig. 7, not shown) an electronic switch which makes use of the Hall effect is fixed to the ear raiser and an actuating magnet therefor is secured to the finger 21.

Abstract: 1,170,029. Coating with metals; nickel alloy. INTERNATIONAL BUSINESS MACHINES CORP. Sept.12, 1968 [Sept.20, 1967], No.43383/68. Headings C7A and C7F. [Also in Division H1] In order to reduce the magneto-strictive shift in a series of vapour deposited Ni-Fe magnetic films, the rate of deposition is reduced, e.g. by varying the temperature of the source, from one film to another through the series. A substrate 14, e.g. a copper plate, is raised at 13 to a support 15 which moves it to a position 21, where the vapour from one or more sources 16 is deposited. The coated substrate is then moved to a position where it is lowered at 14. In a modification Fig. 2, (not shown) the substrates are moved by an endless belt. A magnetic field may be applied during deposition by coils 19, and the substrates heated to e.g. 200 to 400‹C. by heaters 18. A focal plane shutter 20, and an ion gauge 17 for measuring the rate of deposition may be provided. A smoothing layer of SiO or Cr may first be applied to the substrate. The magnetic alloy may be Ni-Fe and may also include from 0 to 10% of one or more of Cr, Pd, Co, Mn, Pt or Au, e.g. (wt.%) 79À8 Ni, 17À2 Fe, 3À0 Co.
