Title: Improvements in devices for sharpening the rotary circular knives of machines for slicing meat and other substances
IPC: B24B3/46
Filed: 1928-10-06
Abstract: 321,040. Fitzpatrick, H. D., (Maatschappij tot Vervaardiging van Snijmachines volgens van Berkel's Patent en van Andere Werktuigen). Oct. 6, 1928. Machine cutters, grinding in situ.- In a device for sharpening the rotary knife of a slicing-machine, a holder is provided carrying a relatively movable grinding-element or elements and is so supported that it is movable into, and out of operative position by sliding movements in the plane of the knife and transversely of that plane; manually-operated means also are provided for releasing a grinding-wheel and a burr-removing wheel from the knife in timed sequence, so that the burr-removing wheel engages the whole of the cutting-edge. The knife 11 is carried by a bearing 10 on which is mounted the holder comprising a casing 92 carrying, in bushes 95, 96, a grinding-wheel 20 and a burr-removing wheel 21, which are spring urged towards the knife. The casing 92 is supported by a pin 45 adjustable in a sleeve 46 by a nut 84, the sleeve being slidable in a socket 47, which is slidable on the guide rod 54 and a slide 79 and is positioned, in operative or inoperative positions, by the engagement of the lower end 89 of the sleeve 46 with a recess 90 or a depression 91, the sleeve being lifted, to allow of sliding on the guides, by a lever 85. Rotatable in the casing 92 is a shaft 105 carrying a cam pin 108 acting on a pin 101 to move the grinder 20, and rotatable on the shaft is a collar 109 carrying a pin 110 engaging a notch 111 in a pin 103 which moves the wheel 21. The collar has thereon lateral pins 112, 113 which, by engagement with a pin 114 on the shaft 105, limit the rotation of the collar thereon. The shaft carries a hand wheel 115, engaged by a spring 116 tending to rotate it counter clockwise, Fig. 3, and on the shaft also is a ratchet-wheel with two notches 119, 120 adapted to be engaged by a pawl 121, pressed by a spring 122 and pivoted on a screw 123, which also carries a trip arm 125 engaging notches in a bar 128 pivoted at 129 in a slot in the bracket 47. A spring 131 presses the bar up to the arm 125. When the knife is to be ground, the wheel 115 is rotated clockwise, moving the pin 108 to move the grinder 20 up to the knife, the pawl 121 engaging the notch 119 to hold the parts in this position. A further slight rotation causes the pin 114 to pick up and rotate the collar 100, thereby moving, through the pin 110, the wheel 21 up to the knife, and the pawl then engaging the notch 120. After sharpening, the lever 85 is pressed to lift the holder &c. clear of the knife, and the bar 128, by engagement with the trip arm 125, moves the pawl 121 to release the ratchet-wheel, the spring 116 then turning the shaft 105 back. The lost motion of the collar 109 causes the wheel 21 to leave the knife after the grinder 20 has been withdrawn, and so to remove the burr on the section of the knife lying between the circumferentially spaced grinder 20 and wheel 21.

Title: Foot-operated control device
IPC: H01C10/50
Filed: 1973-06-20
Abstract: 1445614 Actuation of switches and rheostats; electric motor control SIEMENS AG 20 June 1973 [26 June 1972] 29394/73 Headings H1N and HIS [Also in Division H2] A foot-control device as used for actuating dental apparatus has a housing 1 incorporating a footbar rest 4 with a friction grip plastics strip 6, an actuating member 2 to arm 16 of which is attached foot application means 3 movable in a horizontal plane in a path within a recess 5, a footplate actuator 10 pivotally hinged at 11, and two depressible actuating elements 8, 9. When the arm 16 of the actuating member 2 is displaced, against the action of restoring means, to various operating positions on either side of a central basic position 2<SP>11</SP>, Fig. 3, the shallowcurved travel-path of the foot application means 3 is achieved by providing the actuating member 2 with an articulated pivotal first bearing 21, 23, 27, the pin 21 describing a concavely curved path, and a slidably guided second bearing 25, 26 which describes a linear path. Alternative embodiments of bearing arrangement to achieve this travel path are described with reference to Figs. 7, 8 (not shown). Movement of the arm 16 acts on a pinion and gearwheel drive 33, 34 of a rotary potentiometer-type rheostat 36 by means of a drive pin 29 attached to the arm engaging with a forked pivotal member 30 attached to the pinion and a cam disc 37 located about the rheostat pivot 35 formed with recesses 38, 39 controls the operational sequence of two switches 40, 41 according to the portion of the arm. Also depressible against spring action is the shroud 19 of the foot application means 3 to actuate a switch 18 which has electrical connection leads carried along the arm 16 and is operable in any position of the means 3. A hinged footplate 10 extending the full width of the foot-control device acts as an actuator for a switch 15, Fig. 2, when downwardly depressed against the action of spring 14, independently of the foot application means 3. Two further switches 42, 44 are respectively operated by depression of the actuating buttons 8, 9, the button 9 having an extension pusher 45 which triggers a latching device 42<SP>1</SP> (described with reference to Figs. 5, 6, not shown) in the form of a push-push operate/retract mechanism by means of which a spring-loaded pin (55) snaps in rearwardly of the end 56 of arm 16 when the actuating member 2 reaches either of its operating end positions and holds the arm latched in such positions until released by a second actuation of button 9. Details of the functional control exercised by the various switches and the rheostat as applied to a dental electric drill are described with reference to Fig. 9 (not shown) in Division H2. The claims are mainly directed to the bearing and movement features for the actuating member 2 acting on electrical switches and/or electrical control means. Specifications 1,445,613, 1,445,612, 1,445,615 and 1,445,616 are referred to.

Abstract: 1,224,167. Automatic control. GEORGE KENT Ltd. June 24, 1968 [June 26, 1967], No.29443/67. Heading G3R. An error signal or a manually adjustable signal may be applied to the input of a control amplifier by appropriate setting of a selector switch and a capacitor connected between the output and input of the amplifier ensures smooth changeover in either sense. In Fig. 1, the difference between electrical signals 6 and 8, corresponding to measured and desired values of a variable to be controlled, is applied to amplifiers 14, 16, 20 deriving proportional, differential and second differential functions of error which are added together and applied to an integrating amplifier 36 the output of which corrects the error in a manner not disclosed. A feedback capacitor 50 produces the integration and the relative magnitudes of the three error components are adjustable by amplifier gain adjusters 30. Changeover to non-automatic control is effected remotely by a switch 66 energizing a relay 62 to move a switch 34 to the other position shown so that a positive or negative signal is applied through a resistor 40 to amplifier 36, instead of the error signal, so that the amplifier output changes at a predetermined rate which may be pre-selected. A switch 54 is also changed over by relay 62 so that a capacitor 60 previously connected to the output of amplifier 36 is connected from output to input to ensure bumpless transfer. When automatic control is restored by opening switch 66 capacitor 60 is reconnected across the output of amplifier 36 and transfer in this sense is also bumpless. Diode limiter circuits 70, 72 and 74 associated with the input and output of amplifier 36 prevent integrator saturation. Modifications are described in which: (a) the three control components are derived by different methods some of which involve fewer amplifiers and components by-passing the integration amplifier which may be adjustable, and some of which involve differentiating the measured value instead of the error. (b) condenser 50 suffices to ensure bumpless transfer without switching an additional capacitor such as 60. (c) more complex signal limiting arrangements involving biased diodes in bridge and transistor circuits are provided.
