IPC: B26D7/30
Abstract: 135,109. Svensson, E. April 2, 1919. Apparatus fitted to meat slicing machines ; automatic - feed weighers. -A feed mechanism for a machine for slicing meat and the like has an adjustment for varying the thickness of the slices and is provided with the electrically actuated device for stopping the feed when a predetermined weight has been cut off. The feedscrew is operated by a cam and pawl and ratchet, the ratchet being returned'on its idle stroke by a, spring connected to a link 15 carried by a member 18 adjustably secured to a slide 24 by means of a pin 23 engaging one of a number of notches 19. The thickness of the slice is varied by engaging a different notch 19 over the pin 23. Cut slices fall on to a plate 39 of a balance, each slice further depressing the plate till electrical contact is made at 41, 42, when an electro-magnet 35 attracts a pivoted arm 33 and knocks up a pair of links 28, 30 which normally are in alinement and retain the slide 24 in its right-hand position. The slide is then pulled to the left by a spring 25 and the feed is stopped since the link 15 is too far to the left to give the feed ratchet any idle stroke. A second electro-magnet 47, energized by the same current, separates the contacts 41, 42 and frees the balance so that the weight on the plate 29 can be read off. The contact 42 is adjustable along an arc having the pivot of the arm 40 as centre, so that the weight of meat required to stop the feed may be varied.

The decorticating-drum 10, Fig. 2, is provided with blades 11 and is supported by rollers 12 running on circular tracks 13. It is driven by a belt or by bevel gearing. The abutments 10<a>, 10<b>, Fig. 4, are supported within the drum. The leaves are passed endlong into the shoot 24, and the stems are caught by the teeth 25 on a carrier wheel 18 running in a groove in a semicircular rim 27. This carries the leaves past one breast and up to a carrier belt 29, Fig. 6, which trnnsfers them to the other carrier wheel 19 and in transit passes them through a reversing-device composed of two twisted plates 36. The leaves are then engaged by the teeth 38 on the wheel 19, carried down a grooved run 37 past the other breast, and finally ejected through a shoot 38. The machine may be mounted for transport upon a motor-truck, and when it is desired to use the machine the driving-chain may ' be transferred from the axle of the truck to a sprocket on a shaft geared to the operative parts of the machine.

Title: Improvements in or relating to servo systems
Inventor: FRANKEL JOHN SEMON
IPC: G05D1/00
Filed: 1961-04-21
Abstract: 946,138. Servo systems. S. SMITH & SONS (ENGLAND) Ltd. April 13,1962 [April 21, 1961], No. 14460/61. Heading G1N. [Also in Division F2] The servo loop of a system (shown in Fig. 1) comprising an amplifier 9 feeding a motor 10 in response to the signal generated by for instance any difference between the rotor positions of a synchro 5 and a command synchro 3, can be broken possibly by interrupting the motor 10 reference phase supply 11, so that a signal results which is the difference between a datum set by the value of the amplifier input signal at the moment of loop interruption, and its value at any subsequent time, the motor 10 driving the rotor of synchro 6 through a differential gear 16 having an input shaft 15 and an output shaft 16 which is independently settable by manually operable datum adjusting member 18. The rotor of synchro 3 is positioned by sensing means 1 possibly responsive to Mach number or indicated air speed. A signal depending upon the rotor position of the synchro 5 is derived from means 7 such as a potentiometer. The servo loop is broken by energizing a relay coil A through switch 12 and thus opening normally closed contacts A1 and closing contacts A2 thereby applying the amplifier output signal to an output circuit 14 such as an air data computer. The magnitude of the output signal depends upon the change in the rotor position of synchro 5 from that at the instance of relay operation, and a change in this output may be effected by the datum adjusting knob 18, the operation of which when the servo loop is closed does not affect the position of shaft 6 beyond causing a temporary disturbance. When several of the above systems are to be used, one datum adjusting knob 18 may be coupled to each of the several differential gears 16 each relay H being selectively energized by a rotary switch. Only the datum of the system the relay H of which is energized will then respond to movement of the knob 18. As an alternative to the relay switching shown in Fig. 1,the reference phase of the motor 10 may be kept connected and the servo loop broken by a pair of change or relay contacts which switch the amplifier output from the motor 10 to the output circuit when required. Alternatively again the amplifier input may be similarly switched. The synchro 5 may be replaced by for instance a mechanical differential 19 (Fig. 3) having a shaft 2 moved by sensing means 1, a shaft 6 driven by the output of the differential 16, and an output shaft 20 which drives an electric pick-off 20 for generating the input signal for amplifier 9. Rate dependent feedback may be introduced into the servo system by a feedback signal from a tachogenerator driven from the shaft 15, and fed to a second input.of the amplifier. Specification 889, 594 is referred to.
