Title: Comparison read-out circuit
IPC: G06V30/224
Filed: 1964-05-26
Abstract: 1,059,179. Sensing records. W. A. FOLSOM. May 26, 1964 [June 10, 1963], No. 21678/64. Heading G4M. The output of a photo-electric or magnetictransducer sensing code marks printed on a document is applied to a bridge circuit, Fig. 4 (not shown) having one arm which follows the input signal immediately and another arm which includes a capacitor (14) and is responsive to the continuance of the input signal. In the presence of background noise capacitor (14) is partly charged and a terminal 18 is positive with respect to a terminal (19) connected to the first arm. When a data mark having a short rise-time is sensed, terminal (19) rapidly becomes more positive than terminal (18), and after a predetermined delay, an output relay is energized. One contact of this relay is closed to connect a resistor across the capacitor (14) so that both bridge arms now act as voltage dividers and are responsive to the steady state data signal. At the end of this signal the circuit reverts to its initial condition.

Title: Improved method and apparatus for the automatic synchronisation of rotary movements and their application to the transmission of images
IPC: H04N5/04
Filed: 1933-08-04
Abstract: 428,041. Maintaining defined speeds of motors. MUTUELLE MOBILIERE SOC. ANON., 4, Rue Montoyer, Brussels. Aug. 4, 1933, No. 21976. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 9, 1934]. [Class 38 (iii)] [See also Group XL] A synchronizing signal acts on an oscillator 14 in a speed governor to vary the speed of a motor 7 when out of synchronism. The synchronizing signals in the coil 14 oscillate it to open a contact 9 and close a contact 26. At synchronism a resistance 4 in the circuit of the motor remains short-circuited through brushes 16, 17 on segments 18, and a resistance 5 remains in circuit through brushes 27, 28 being off segments 29. The supply to the motor is thus unchanged. If the motor is in advance, brushes 16, 17 are no longer in contact with the segments 18 when the contact 9 is opened, and the resistance 4 is switched in circuit to retard the motor. If, on the contrary, the motor lags, the resistance 5 is short-circuited through the brushes 27, 28 being in contact with the segments 29, and the motor accelerates. According to modifications: the resistances or chokes 4, 5 are in shunt with the field of a shunt-wound motor, Fig. 3 (not shown), or in series with the armature, Fig. 4 (not shown) ; the switches short-circuit part of the field winding or switch a supplementary field winding, Fig. 5 (not shown) ; a resistance in shunt with the field of a series-wound motor is varied, Fig. 6 (not shown) ; part of the secondary of a transformer supplying the armature of a compensated repulsion motor is switched in and out of circuit, Fig. 7 (not shown) ; polarized conducting semicircular rings are used in place of the segments 18, 29, Fig. 8 (not shown).

Abstract: 422,223. Linear dimension gauges. WILSON, E. G., Netherwood, Far Moss Road, Blundellsands, near Liverpool. Sept. 9, 1933, No. 22227. [Class 106 (ii)] The thickness of sheet material is measured by passing the material between independently operable narrow feeler discs and feeding rollers below the same, means adjacent the discs being moved according to the movement of the discs and caused to mark the thickness on the material. The feeler wheel 1 is rotatably mounted on a pin 2a on a bar 2 above a feed roller 3 protruding through a table 4 supporting a sheet 5 of leather &c. The arm 2 is connected at one end to a guide rod 6 slidable in a crossbar of the frame under tension of a spring 8 while the other end is pivoted on a shaft 9. A marking disc 10 attached to a spindle 10a is mounted adjacent the wheel 1 in the lower end of a vertical rod 11 pivotally mounted on a pin 12 fixed to a rocker bar 13 also pivoted on the shaft 9. The rod 11 slides through a frame crossbar and between this and the pin 12 carries a pin 15 on which is pivoted a quadrant lever 16, 16<a>, the upper arm of which is connected by a link 17 to a stud 18 fixed in an extension 2b of the arm 2 above the shaft 9. The quadrant meshes with a pinion 21 connected to the wheel 10 through yielding coupling members 19, 20. A locating disc 22 is secured to the spindle 10<a> and has near the circumference a ring of pegs 22<a> arranged to be engaged by a justifying cone centre attached to a rod yieldingly and adjustably supported at the ends from brackets secured to the bar 2. Pivoted on a pin 27 secured to a lug 2d on the bar 2 is a lever 28, 29 of which the upper face of the end of the arm 27 engages a stud 30 adjustably secured in an extension 13<a> of the rocker bar 13 while the lower face engages a spring 31 fixed to the bar 2. The shorter arm 28 carries a roller 33 adapted to engage a roller 34 on the disc 35 fixed to the shaft 9. An inking pad 36 is carried by a pivoted spring arm 37. In use the roller 1 drops according to the thickness of leather and the movement of the arm 2 moves down, pushing over rod 17 to turn the quadrant and wheel 10 to position corresponding type. When the shaft 9 rotates, the lever 29 is moved down against the spring 31 and the arm 13 with wheel 10 follows it to make an impression on the leather of the thickness measured.

The movable support comprises a U-shaped frame having a cross-bar 11 and arms 12. Each arm 12 is bifurcated at its end 13 to provide a support for the shaft 7. A handle 18 is attached to the cross-bar 11. The support also comprises a shaft 14 passing through holes in the ends of the arms 12 remote from the bifurcated ends 13. The shaft 14 is pivotally attached to crank arms 15 which in turn are pivotally attached to the axles 16 of the ground-engaging wheels 17. The support is moved between its operative and inoperative positions by means of a manual control comprising a lever 19, rod 20 and crank 21 attached to the shaft 14. The support may be locked in its inoperative position by means of a lever 25 which is spring-biased to clamp the rod 20, the clamp being released by means of a plunger 28. The support may be moved to a further position in which in its inoperative position, a brake is applied to the flange 2 of the reel 1 or to the shaft 7. In a preferred embodiment, a cable 4 is wound on the reel 1, one end of which cable is attached to a socket 5 mounted on a flange 2 of the reel, and the other end of which cable carries a plug 6. The drive wheels 8 are preferably of the same diameter as the cable-receiving surface 3 of the reel 1 whereby the surface 3 is driven at the same linear speed as the ground-engaging wheels 17. The wheeled carriage may be separate from or form part of a machine on which the reel is to be used, e.g. electrically driven lawn-mower or hedge-cutter or power tool.

Apparatus for automatically closing the liquid flow control valve described in Specification 803,738 when the liquid level in a tank being filled by the valve reaches a desired level, includes a Venturi discharge nozzle 54 in the outlet 3 connected on its expansion side by a duct 55 to a flexible U tube 56 whose shorter limb opens into a chamber 52 closed by a diaphragm 47 and longer limb extends downwardly at its end to the desired filling level of the tank. The diaphragm 47 is urged upwardly by a spring 51 and connected to a valve piston 43 slidable in a cylinder 40 having connections 41, 42 with the balancing and valve chambers 5, 4 respectively. Normally the valve piston 43 closes the connection 42 to cut off communication between the chambers.
