Abstract: 304,533. M°ller, J. S., and Nielsen, H. April 20, 1928. Percussive hand-tools. - The striker 11 of a centrifugal hammer is pivoted to a block 6 which is journaled in ball bearings 5 and driven by a flexible shaft, and after each rebound the striker is locked by a spring-pressed lever 16 until it has passed clear of the tool 4, when the lever 16 is tripped by a lug 22 on a slider 23, which is held in the path of the lever 16 as long as the starting-lever 30 is depressed. On the release of this lever, a spring 27 pushes the lug 22 clear of the path of the lever 16, as shown, so that the striker remains permanently locked in the retracted position shown in Fig. 4. The parts are so proportioned that when in this position the centra of gravity of the rotating parts lies in the axis of revolution. The striking face 34 is obtained by cutting out a recess as shown, and a lug 12 is formed on the opposite side to limit the swing.

Title: Improvements in and relating to mercury vapour lamps
IPC: H01J61/073
Filed: 1946-04-17
Abstract: 626,303. Discharge lamps. GENERAL ELECTRIC CO., Ltd., and FRANCIS, V. J. April 17, 1946, Nos. 11870 and 17975. [Class 39 (i)] In a high-pressure gas or vapour electric discharge lamp for operation on A.C., and having solid electrodes of highly refractory material, development of hot spots with consequent vaporization of the electrode material is minimized by inserting activating material in each electrode near the terminal surface thereof in a recess which is almost but not quite closed by a layer of highly refractory metal, through or around which the activating material can diffuse to said terminal surface. In one embodiment a cylindrical molybdenum electrode 11 has an axial hole in which is inserted a plug 14 of activating material, which may be thoria or zirconia or a mixture of both, the hole being closed by a plug 15 of tungsten which projects slightly beyond the surface 18 of the electrode, and has flats at its sides to form passages for the penetration of the activating material. The hole may extend throughout the length of the electrode. Alternatively, the hole may be a transverse slot in which the plug of activating material is inserted, closure being made by a tungsten plug having its central region of reduced thickness to provide passages, and projecting slightly beyond the surface of the electrode. It may not be necessary to provide special passages, as sufficient space for the passage of activating material may be obtained with, for example, a nominally circular plug and hole. Activating material for starting purposes may be provided in addition to that inserted in the electrodes.

Title: Control devices
IPC: G06K7/00
Filed: 1972-03-14
Abstract: 1367385 Fluid displacement-indicating apparatus; displacement encoder AIR LOGIC PTY Ltd 14 March 1972 [22 March 1971] 11914/72 Headings G4P and G4H [Also in Division G3] A device which may be used in the measurement of displacement, or in the positioning, of a movable member, e.g. a machine part, includes an array of sensors which sense apertures in a control element moved in correspondence with the movable member. The apertures and sensors are so arranged that adjacent apertures are sensed in turn by successive sensors, e.g. as by the Vernier principle. The apertures are sensed by photo-cells or pneumatic sensors. In the embodiment described the control element is a tape 16, Fig. 4B, which is moved over a receiver manifold block 12. The block 12 has ducts connected to pneumatic sensors which receive air, when a tape aperture is aligned with a duct, from a delivery block (11) having a similar arrangement of ducts. The ducts in row AA are spaced at 9/100 of a unit, whereas the apertures in the corresponding row of the tape are spaced at 10/100 of a unit. Sensors connected to ducts C, D, E detect apertures at 1, 2, and 3 units from a datum mark 26. Alternatively these unit distances could be represented by binary coded apertures, or by a single row of apertures driving a counter. Ducts in row BB are spaced at 10/100 of a unit. As applied to the positioning of a machine part, Fig. 5., pneumatic switches are used to select ducts in the receiver 12 and delivery 11 blocks corresponding to desired units (switch 20), tenths (switch 21) and hundredths (switch 22) of a unit of movement. When the tape reaches the corresponding units point a circuit is formed, setting bi-stable 23. When it reaches the 1/10 point gate 24 is enabled and when the 1/100 point gate 25 is enabled. If gate 32 is giving an output, amplifier 28 gives an output indicating that the machine part is in the required position. Gate 32 gives no output if there is partial registration of a duct in row AA with a tape hole when switch 22 is set to any hundredths position 6-9 or 0. Such false registration is detected by a circuit comprising gates 30-32 driven by a receiver sensing an additional aperture (F) in the tape, the aperture being so arranged that it is not sensed when the tape positioned lies in the first half of the 1/10 unit interval.

Title: Improvements in or relating to governors
IPC: G05D13/00
Filed: 1919-05-13
Abstract: 149,430. Glaser, W. H. May 13, 1919. Speed-maintaining systems.-A governor for controlling the uniform or variable, motion of a member 14 comprises a rotating body consisting preferably of two parts 27, 28, mounted on a shaft 12 which carries one element 49 of a differential' gear, another element 15 being connected to the member 14, while the planet wheel 50 is connected by a. frame 52, a double pawl 54, a. ratchetwheel 58, and switch arm 72 to the switch controlling the motor driving the member 14. The wheel 27, 28 is driven by a wheel 16 through an electro-magnetic clutch 22, 21 connected to the wheel 16 and loosely mounted on the shaft 12, so that, when the coil 22 is energized by means of the slip-rings 23, 34, the member 17 is drawn into contact with the member 27 and drives the members 27, 28 through a friction ring 21. If the speed of the wheel 27, 28 exceeds the normal, balls 31 move outwards and move the member 28 axially, thereby breaking the circuit of the coil 22 and allowing the spring 19 to move the member 17 out of contact with the member 27. If an accelerated motion is to be copied by the member 14, the ring 21 is made of material that allows a certain amount of slip between the members 17 and 27. If a retarded motion is to be copied, a coil 41 in a slidable member 40 is energized so as to move the friction ring 47 against an armature 39 connected to the member 28, and thereby brake the latter. Specification 149,731 is referred to.

Title: Improvements in or relating to delivery mechanism for printing and other machines
IPC: B65H1/18
Filed: 1946-04-18
Abstract: 629,252. Printing-machines; sheet delivery apparatus. BOBST ET FILS SOC. ANON., J. April 18, 1946, No. 12090. Convention date, April 23, 1945. [Classes 100 (i) and 100 (ii)] In a delivery mechanism for printing and other machines a feeler is arranged to engage the uppermost sheet of a pile of sheets and to control the angular movement of an oscillating member operatively connected to a means for controlling the lowering of the pile, such that the lowering means is inoperative until a predetermined height of the pile is reached, operative when this height is reached, and, when the pile exceeds a certain height, the machine is stopped by the oscillating member. A shaft 5 has secured thereto a feeler 6 and member 23 having a lug 23a disposed between a spring 25 and a screw 24 carried by a member 7 oscillated with a constant amplitude through a lever 9 by a link 10, so that the feeler 6 and member 23 are oscillated through a diminishing amplitude. as the height of the pile increases. A cam member 26 pivoted at 27 to the member 23 carries a screw 29 which is held by a spring 28 in contact with a shoulder 30 on the member 7. The member 26 also carries a screw 31 engaging a lever 20 which normally holds stationary a plate 13 carrying a ratchet pawl 14 co-operating with a ratchet-wheel 15. As the sheets are fed to the pile 17 the lower position of the feeler is gradually raised so that the member 26 turns about its pivot 27 until the screw 31 operates the lever 20 sufficiently to release the plate 13. The plate 13 then rotates counter-clockwise under the action of a spring 19 and is then returned to its initial position by a link 11 which is constantly oscillated by the lever 9. This action turns the ratchet-wheel and is repeated until the pile is lowered to such an extent that the lever 20 again retains the plate 13. The ratchet-wheel 15 is rotatably-mounted on the shaft 35 to which the sprocket-wheels of the chains 16 supporting the pile table are secured. The wheel 15 carries a pawl 38 engaging a ratchet-wheel 37 fast on the shaft 35, and is secured to a sleeve 42 held against free rotation by a brake 40. The weight of the pile tends to lower it but this is prevented by the pawl 38, ratchet-wheel 15 and brake, until the latter is overcome by the turning of the wheel 15 by the pawl 14. A hand-wheel 36 is provided on the shaft 35 to allow of the pile table being raised when desired. When a pile of sheets is removed, a grating 34 is inserted to receive the sheets delivered during such removal. If the pile delivered to the grating reaches an abnormal height, the cam member 26 is rotated about its pivot an amount sufficient for a screw 32 on the cam member to actuate a switch 33 which stops the machine.

Title: Improvements in and relating to electric circuit breakers
IPC: H01H33/98
Filed: 1931-04-23
Abstract: 377,707. Oil switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Turnpenny, W. H. ; 12-c, Wilkins Avenue, Albany, and Skeats, W. F. ; 211, 2nd Street, Scotia, both in New York, U.S.A.) April 23, 1931, No. 12121. Convention date, April 23, 1930. [Class 38 (v).] Two breaks between two pairs of abutting contacts in series are produced within the oil-filled explosion pots (one only of which is shown) of a switch. As the bridging contact member 7 with the tubular contact 6 is moved downwards, the floating intermediate contact 5 follows it under the action of the spring 24 and the spring-mounted main contact 4 also follows under the actions of its spring 10. After a small combined movement, the contact 4 is held up by a conducting inner portion 8 of the container. An arc is then drawn between the abutting contacts 4, 5 and when, soon afterwards, the intermediate contact 5 (which carries a spider 22 against which the spring 24 bears) is held up in turn by a cupped insulating disc 1, the tubular contact 6 is withdrawn from abutting engagement with the flat face 26 of the intermediate contacts. The pressure produced at the first arc now forces oil radially across the second, down the tubular contact 6 and out through passages 28 or through the open end of the contact into the main body of the oil. When very heavy currents are interrupted, the oil pressure developed may cause the contact 4 to " pop-back " notwithstanding the provision of pressure equalizing passages 8a. In this event the arc moves over to the flared lower sides of the portion 8. An orifice 12a prevents air locks so that the explosion chamber can fill up again with oil. An insulating liner 13 shields the explosion chamber from flash-over. Specifications 13852/02, [Class 38, Electricity, Regulating &c.], and 193,136, [Class 38 (v), Electric switches &c.], are referred to.
