Title: Improvements in method and device for rounding off and polishing the ends of thermo-plastic brush bristles
IPC: A46D9/02
Filed: 1950-04-03
Abstract: 689,494. Method and apparatus for shaping bristle tips. BROSSE & J. DUPONT REUNIS. April 3, 1950 [Jan. 11, 1950], No. 8312/50. Class 19. Rounding and polishing of the tips of thermoplastic bristles are effected by subjecting the tips of the bristles mounted on the brush to the hammering and rubbing action of hard non- flexible bristle-tip shaping and forming tool elements having rounded non-abrasive polishing ends moving substantially at right angles to the line of the bristles at a rapid rate of relative displacement thereto so as to cause a rapid repetitive lateral hammering and rubbing of the bristle tips thereby generating sufficient heat to soften the bristle tips whereby the tips are rounded in the relative moving direction of the tool elements. By reversing the movement of the tool elements the bristle tips may be shaped on two opposite sides. If the brush has a flat or regular concave or convex face complementary to the surface generated by the tips of the tool-elements, then by rotating the brush about its axis during the action of the tool elements the bristle tips may be acted upon uniformly all round the bristle ends. Brushes having faces of more complex contour may be treated by means of two shaping tools of appropriate profile operating in two different directions; this procedure is described with reference to a brush having a sinuous contour. Suitable apparatus (Fig. 1) for treating a brush having a concave contour comprises a disc-like shaping tool supporting member 1 having a convex spherical surface 1a in a peripheral annular zone provided with cylindrical steel pins 4 of 6-8 mms. length with hemi-spherical paraboloidal tips. The brush 8 is held in a mechanically or manually adjustable clamp 7 secured to a shaft 9 rotatable as shown by a crank 12 and axially displaceable in its bearings. The tool support 1 is rapidly rotated and the bristle tips brought into engagement with the tips of the shaping pins whereupon the brush is slowly rotated by crank 12 and the desired all-round shaping is effected. If the brush is flat or convex the disc-like tool-support used is correspondingly flat or concave in shape. The pins may be mixed pins of two different lengths when the bristles are of mixed long and short lengths. Instead of pins, the tool elements may take the form of upstanding blades 13 (Fig. 8) having their top edges rounded and complementary to the contour of the brush to be treated. Alternatively, the tool elements may be the projections obtained by milling a suitable supporting surface, the ends of the projections being rounded and then polished. The supporting surface may be on, instead of a disc, a cylinder or other surface of revolution.

Abstract: 1413044 Electronic counters TOKYO SHIBAURA ELECTRIC CO Ltd 21 Feb 1973 [25 Feb 1972] 8409/73 Heading G4A [Also in Division H3] A binary counter employing complementary FETs comprises a cascaded connection of at least a first, a second and third inverters 1-3, the output of the third inverter 3 being connected to the input of the first inverter 1, clock signals Q 1 , Q 1  for causing at least two inverters 1, 2 to operate alternately whereby an output signal having a frequency equal to half that of the clock signals is obtained from the output of one of the inverters. In operation, when the clock signals Q 1 , Q 1  are in their "0", "1" states respectively FETs 13, 14 are conductive while FETs 23, 24 are non-conductive so that clocked inverter 1 alone is operative. An input of "1" is inverted by 12 to a "0" which is-stored by an input capacitance ca. Subsequently inverter 1 is turned off and inverter 2 rendered operative so that FET 21 inverts the stored "0" to a "1" which is stored in a capacitance cb and also inverted by FET 32 to a "0" level which is fed back to input of 1. A further cycle of the clock pulses is required before the output at Q 2  returns to the "1" level thus achieving a division by two of the clock pulse rate. The third inverter 3 may also be clocked by the pulses applied to the second inverter and may also be interposed between the first and second inverters. The inverters may be rearranged (Fig. 3, not shown) so that the input is applied to FETs 13, 14 with the clock pulses applied to FETs 11, 12. In an alternative embodiment (see Fig. 5A), the first and third inverters are clocked, a fourth inverter 50 is connected at the output of the third inverter and a fifth and a sixth inverters 4, 6 clocked by the pulses applied to the third, first inverters respectively are connected between the output and input of the second, fourth inverters respectively for maintaining the logic levels at the outputs of the first, third inverters. The second and fourth inverters may each include a NAND gate to one input of which a control signal is applied to inhibit or to initiate counting. In the embodiment of Fig. 6A (not shown), the second and fourth inverters include NOR gates for resetting the counter. In the embodiment of Fig. 7A (not shown), the first and third inverters include NAND gates for resetting the counter. In the embodiment of Fig. 8A (not shown), the fifth, sixth feed-back inverters include NAND gates.  A multi-stage counter may be built by cascading a number of binary counters with complementary outputs derived from each stage being used as clock inputs for the following stage.

Title: Improvements in and relating to door latches
IPC: E05C1/16
Filed: 1939-03-18
Abstract: 527,971. Latches. TAYLOR, J. W. March 18, 1939, No. 8731. [Class 44] Relates to latch mechanism of the kind in which the bolt is held in partly retracted position when the door is open, and is released by inward movement of the bolt on engaging the striking plate when the door is being closed, the bolt being then fully shot by its spring and deadlocked. The bolt 1, which may be cast, has an aperture la to receive a compression spring, not shown, and also has a bifurcated tail providing arms 2, 3, each having a terminal projection 11 and lateral cam surface 15. The symmetrical arrangement allows the bolt to be reversed for right or left-hand use, only the uppermost projection 11 and lowermost cam 15 being operative as described below. The follower which is biassed anticlockwise by spring 16 bearing against an arcuate projection 17 is rotatable clockwise by inside handle 8 or outside cylinder lock, not shown, and has an arm 9 co-operating with projection 11 on bolt arm 2 to retract the bolt, and an eccentric cam surface 7 terminating in a shoulder 14. Fig. 3 shows the bolt deadlocked by a lever 4, pivoted at 5, biassed to raised position by spring 6 and ending in a hook projection 13 engaging behind the end of arm 3. The projection is extended laterally so that cam 7 overlies the extension. In clockwise rotation of the follower, cam 7 depresses lever 4 and arm 9 then retracts the bolt so that bolt arm 3 rides over hook 13, when the bolt has been partly withdrawn, shoulder 14, which now projects below bolt arm 3, snaps past hook 13, by which its movement is prevented, so that the bolt, although capable of further retraction to release it from the keeper, cannot return to fully shot position, when the handle &c. is released. When the door is subsequently closed, the bolt is moved inwards by the striking plate, the lower cam 15 depressing lever 4 to disengage hook 13 from shoulder 14. Spring 16 then returns the follower to the position shown, and the bolt is shot by its spring and deadlocked by hook 13. Alternative dispositions of lever 4 are described. A thimble 25, rotatable by the outside cylinder lock, may retract the bolt by direct engagement with projection 17, but as shown, it rotates a second concentrically mounted member 26 with a projection 27 engaging projection 17. Rotation of member 26 in reverse direction brings its projection 27 into engagement with the opposite side of projection 17 and blocks the inside handle. Additional manually operated dead-locking means such as is described in Specification 524,590 may be provided.
