Title: Improvements in or relating to machine tools
IPC: B23Q15/00
Filed: 1961-02-20
Abstract: 959,594. Machine tool details. CROSS CO. Feb. 20, 1961 [March 7, 1960], No. 6225/61. Headings B3B and B3C. [Also in Division G1] A machine tool head 12, Fig. 2, carrying drills 16, 18, is slidable on a base 10 towards and away from a workpiece 14. Inductance coils 28, 30, carried by a member 32 are fixed in relation to the base 10, and apertures 34, 36, in member 32 allow the drills to pass through the coils to drill the work. The coils may be embedded in the member 32 or they may be wound on bobbins inserted in member 32, the bobbins acting as drill bushes. Dogs Al, A2 carried by head 12 are adjusted to actuate limit switches LS1, LS2 at the instant when drills 16, 18 are just entering coils 28, 30 if the drills are the required length, and a trouble indication will not be transmitted. However, if a drill is broken or set at an incorrect length an oscillator circuit including the coil will carry a signal which is amplified and either operates a warning light or stops the machine. Limit switches LS1, LS2 may be replaced by variable inductances, and the coils may be in axially stepped relationship so that the drills will enter the coils simultaneously, thus allowing only one switch to be used. In a modification, Fig. 5, normal length and unbroken drills 16<SP>1</SP>, 18<SP>1</SP> never leave coils 28<SP>1</SP>, 30<SP>1</SP> and a trouble indication will not be produced until one of the drills is not disposed in a coil. Specification 936,953 is referred to.

Title: Improvements in and relating to the forcing of seed plants
IPC: A01G31/06
Filed: 1937-03-05
Abstract: 478,403. Treatment of seeds and growing plants; germinating-appliances. PERIN, G. March 5, 1937, No. 6636. Convention date, March 5, 1936. [Classes 6 (ii) and 58] In a cabinet for the germination of seeds and growth of seedlings comprising a number of groups of trays arranged at different levels and means for intermittently supplying a nutritive liquid to the uppermost group, a float chamber is arranged to receive the liquid after it has passed through a group of trays and, when a particular level is reached in the chamber, to allow the liquid to pass into the next lower group, so that the seeds in the trays are automatically subjected to the action of the liquid for a relatively short time. The cabinet is air tight and insulated. The seeds are spread on screens 19 in the trays 8 and the nutritive liquid is supplied through pipes 18. When the liquid rises in the float chamber 15 the float 20, acting through an adjustable stop, causes a counter-balanced lever 22 to swing back through the vertical position, thus moving a slotted sector 24 and bringing the end of the slot into engagement with a pin on a rod 25 controlling a valve 26. The valve being thus opened the liquid escapes rapidly until its level reaches the upper edge of a small inner chamber 27, when it flows more slowly. It passes through pipes 18a into the next lower group of trays, where the operation is repeated. The Specification as open to inspection under Sect. 91 states that carbon dioxide is admitted to the cabinet to increase the carbon dioxide content of the air therein. The air may be passed through the flame of a burner in a compartment in the cabinet, the products of combustion passing into the cabinet with the air. This subject-matter does-not appear in the Specification as accepted.

IPC: B41J23/12
Filed: 1930-02-28
Abstract: 340,861. Typewriters. WADE, H., 111, Hatton Garden, London.-(Electromatic Typewriters, Inc. ; 60, Commercial Street, Rochester, New York, U.S.A.) Feb. 28, 1930, No. 6676. [Class 100 (iv).] Relay-actions.-In actions comprising a lever provided with a key-controlled cam co-operating with a driving-roller, (i) two like cams connected by a pivot are arranged on opposite sides of the lever, the arrangement causing the drive to be transmitted in the plane of the lever, and (ii) the cam may be controlled by a detent provided with a returning-spring and having lost-motion engagement with a key-lever so that the detent is normally operated by a substantial movement of the key-lever, but can be operated repeatedly without allowing the key-lever to return fully. In the mechanism shown in Figs. 1 and 6, two like cams 20, 21 are arranged close to and on opposite sides of a sheetmetal lever 12 and are connected by a pivot 24 having an enlargement 25 mounted in the lever. The lever rocks on a rod 13 and is connected by a link 15 to a type-bar or other part. The cam 21 has an elongated hub 23 co-operating with a spring- urged arm 26 loosely mounted on a pivot 11 on the lever. The cam 20 has stops 32 co-operating with stops 30, 31 on a detent 29 which is secured to the pin 11 and has a finger 33 having lost-motion engagement with the forked end 35 of a key-lever 16. A returning-spring 36 normally holds the finger in contact with one side of a hole 34 in the lever. On depression of the key-lever, the stop 30 is released from one of the stops 32, the arm 26 moves the cams into engagement with the roller, and the lever is rocked, movement continuing until the other stop 32 is arrested by the stop 31. On release of the keylever, it is returned into contact with an adjustable stop 38 by a spring 37, the detent is returned by the spring 36, and the arm 26 turns the cams slightly until they are arrested by the stop 30. The lost-motion connection 33, 35 permits of substantial depression of the key-lever before the detent is operated, and in repeated operation, the key-lever need not return to the normal position, since the detent is returned independently by the spring 36.

Abstract: 543,562. Attaching labels. AMERICAN TOBACCO CO. May 27, 1941, Nos. 6786 and 6787. Convention dates, June 11, 1940 and June 14, 1941. [Class 73] A machine for stapling a tag to the string of a bag of the string closure type comprises means for feeding the bag and the tag to the anvil of a stapling machine and an oscillating and reciprocating hook to guide the string into position. The machine is stopped automatically if the supply of tags fails. Filled bags containing tobacco are pushed intermittently in line up a slope 352 so that each bag rests on a table 356 while its tag is secured. This feeding mechanism is driven from the 'tobacco filling machine, and the line of bags is prevented from buckling by a plate 470. The bag at the operating position is held down by a spring arm 362 while its pendent string is hooked and drawn over the stapling anvil by a finger extending from a member 366 pivoted at 404 to a cam-actuated slide 368 and slotted to engage a pin 408 on a second cam-actuated slide 370. A magazine 80 contains a pile of tags T, the lowermost being fed by fingers 285 stepped to engage the bottom tag, those above the bottom being held back by a finger 260. To stop the feed the pile may be raised by a handle on a rod 320 secured to arms 328 under the pile. The edge of the lowermost tag, which has been moved by the fingers 285 is gripped by jaws pivoted on a spindle 146 carried by a cam-actuated slide 86, the jaws being opened and shut by cams 166, 182 on a second cam-actuated slide 90. The tag is delivered to a pair B of a plurality of pairs on a spider 134 intermittently rotated. The jaws are urged to their closed positions by springs and opened by a fixed cam after reaching the stapling anvil. When the jaws B have moved one step the tag is pushed between a support 430 and a spring pressed arm 432. If the arm is not thus raised a switch is moved to stop the machine. The arm 432 is also fitted with a handle 448, which can be used to stop the machine. U.S.A. Specifications 2,207,912, 2,207,913 and 2,207,914 are referred to.

Title: Automatic prepayment meter for electricity, gas, water, and the like
IPC: G07F15/08
Filed: 1928-03-05
Abstract: 286,628. Allgemeine Elektricitõts- Ges., (Assignees of Lulofs W., and Hanson, A. F. E.). March 5, 1927, [Convention date]. Counters affording several rates of actuation.-A prepayment meter for electricity, gas, water, &c. which registers at a lower rate after a certain quantity has been consumed in a predetermined period is so arranged that, if less than this quantitv has been consumed in the predetermined period, the unused units at the higher rate are added to the fellowing period, the mechanism being zeroized after a certain number of periods. The meter is shown in Figs. 1 and 2 in the position in which the kilowatt-hours charged at the higher rate are not yet exhausted. The meter drives the recording train through a gear train 1 - - 4, of which the wheel 3 is always in engagement with the wheel 5, which drives a gear-wheel 7 through an intermediate wheel 6. On the spindle of the wheel 7 is a worm 8 driving a worm-wheel 9. The toothed wheels 2, 3, 5 are mounted on a lever 10, one arm of which is pressed against a disc 12 by a spring 11. The disc 12 is provided with a pin 13 which enters a slot in the worm-wheel so as to be turned thereby and tension the spring 14. The indication of the kilowatt-hours charged at the higher rate is effected by the year-wheel 15, which is rigidly connected to the disc 19 and mounted on the same shaft as the worm-wheel 9 and disc 12. The disc 19 is provided, as is the worm-wheel 9, with a slot 20, Fig. 2, into which the pin 13 fits. The year-wheel 15 has on its periphery twelve teeth, of different lengths corresponding to the months of the year, and is turned through the space of one tooth by the Supply Company's inspector at the end of each month by turning a lever 17 until it contacts with a stop 18. The lever 17 may be moved by pulling out the coin receptacle. When the worm-wheel 9 has been driven by the meter to such an extent that the pin 13 is opposite the slot 20 in the disc 19, the disc 12 is moved upwards by the lever 10 and spring 11, pushing the pin 13 into the slot 20. At the same time the wheel 5 is disengaged from the wheel 6 and engaged with the wheel 1<1>, and the wheel 2 is disengaged from the wheel 1. The counting gear is then driven through the train 1<1>, 5, 3, 4 and registers at a lower rate. At the end of a year a cam on the disc 19 moves a projection 23 on the movable bearing 24 for the worm 8, thereby disengaging the worm. from the worm-wheel 9 and permitting the disc 12 and worm-wheel 9 to be returned to the starting position by the spring 14. The monthly movement of the lever 17 may alternatively be effected by a clock or a Ferraris or synchronous motor, a spring being gradually tensioned for a month and then released by a switch device setting forward the lever 17. A visual or acoustic signal may be given to indicate when registration at the lower rate starts.

Abstract: 1,015,751. Coating webs. COTTON SILK & MAN MADE FIBRES RESEARCH ASSOCIATION. Feb. 20, 1964 [Feb. 20, 1963], No.6907/63. Heading D1L. Apparatus for continuously applying a specific amount of substance (e.g. size) per unit length to a moving sheet of material A comprises a mean liquid container B through which the material is advanced, a mixing trough F opening directly into container B, a smaller container N 1  means, e.g. a pump P, for circulating liquid through containers N and F at a rate greater than the rate of take up of liquid by the material, flow control means, e.g. a weir M whereby changes in the rate of take up of liquid from container B cause changes in the level of liquid in the smaller container N, means, e.g. a pump T<SP>1</SP> and pipe T, for continuously supplying liquor containing or consisting of said substance to said smaller container N at a rate corresponding to the desired rate of take-up by the material A and means for feeding diluent, e.g. water, to the smaller container N at such a rate that the total amount of liquid in the apparatus is kept constant. In the form shown the mixing trough F has a further duct L leading, via the adjustable weir M, to the smaller container N. Fresh water is lead to the container N through a slot S from a container R in which a constant level of water is maintained by ball-cock means; thus the level of liquid in container N is also kept constant. The stock from pipe T which is delivered by a pump T<SP>1</SP> driven from the main machine drive is mixed with fresh water and liquid from the weir M in container N by a rotor Y, the resulting liquid being fed by a pump P to the centre of the mixing container F. Perforated steam pipes U, V and U, may be provided to cause mixing; alternatively if heat is not required mechanical mixers may be provided. The mixing container F opens into the main container B via narrow ducts H, G. The horizontal cross-section of containers N and R is arranged to be a small fraction of that of containers B and F so that the liquid level therein is very sensitive to changes in take up rate.
