Abstract: 1,217,251. Programmed draughting. DATA RESOLVED TOOLS PTY. Ltd. May 7, 1968 [May 8, 1967], No.21560/68. Heading G3N. [Also in Division G1] A three-dimensional tracing unit for producing orthographic views of an object e.g. a model, comprises a base 10, a pair of side frames 11 upstanding from the base and supporting a pair of parallel guide tracks 12 for a main carriage 18 which is movable in an X-direction, the carriage 18 having secondary guide tracks extending thereacross to guide movement of a secondary carriage 22 in a Y-direction, the secondary carriage 22 having a guide for movement of a probe 30 in a Z-direction, a table 15 on one of the side frames 11, a track extending over the table 15 coupled to the main carriage 18 for movement therewith in the X-direction, this track guiding an output carriage 41 for movement therealong in response to movement of the probe 30 in either of the Y or Z directions, the carriage 41 being provided with a spring loaded pencil or the like to produce a tracing on the table 15. The unit may also be coupled to an electric typewriter for punching tapes through an encoder for use in the control of milling machines. In the construction described the table 15 produces drawings taken in the X-2 plane of the model, whilst a further table is disposed in the other side frame 11 together with an associated guide track and output carriage to produce drawings taken in the X-Y plane. Contact of the probe 30 with the model is sensed by electrical limit switches and these control a motor driving the probe in the 2 directions. Movement of the probe are sensed by a pulse generator and this feeds signals to a stepping motor which controls the position of the carriage 41 on its guide track over the table 15. Similarly movements of the secondary carriage 22 on the carriage 18 are sensed by a pulse generator controlling a stepping motor on the output carriage of the table on the other of the side frames 11. Thus movements in the X-direction are accommodated by the direct connection between the carriage 18 and the guide tracks for the output carriages on the tracing tables, whilst movements in the other two directions are sensed electrically and stepping motors are used to convey the sensed movements to the tracing tables. The various carriages are guided by rollers engaging tracks of circular section.

Abstract: 891,543. Packaging machines. SCHWEIZERISCHE INDUSTRIE-GESELLSCHAFT. June 29, 1959 [Aug. 15, 1958 ; Nov. 19, 1958], No. 22161/59. Class 94(1). [Also in Group XXX] Flat objects, such as biscuits, supplied continuously to a feeding device from which they are removed by a reciprocating ejector and fed to a packaging machine, are automatically diverted by means of a pivoted flap when the rate of supply exceeds the rate of removal from the device. As shown, Fig. 1, biscuits 3 are fed on edge from a conveyer 1 along a channel 4, over a flap 9 pivoted about an axis 10, and over a channel 4<SP>1</SP> to a vertical channel 411 from which they are removed by a reciprocating slide 7. If less biscuits are ejected than are supplied by the conveyer 1, the biscuits are forced into a position substantially normal to the channel 4<SP>1</SP>, thereby raising pivoted feelers 13 which close a switch to start a motor 22 to swing the flap 9 into alignment with a branch channel 11 feeding a conveyer 12. If there is an insufficient number of biscuits in the channel 4<SP>1</SP>, feelers 14 will drop thereby closing switches 20 in the circuit of a solenoid 26 which stops movement of the slide 7 by means of a pivoted lever 27. In a second embodiment, Fig. 6, the biscuits are fed to the conveyer 1 down a shoot 51, a rotating brush 57 imparting an additional impulse to the biscuits during the transfer to the conveyer. Feelers 13, on detecting an excess of biscuits in the feed channel 53 close a circuit to pivot up the flap 9 to deflect biscuits down a shoot 11 to the second conveyer 12. A section 54 of the feed channel is vibrated on pivoted links 56 by means of a support 60, secured to the section 54 and urged against a rotating eccentric 59 by means of a spring 58.

Filed: 1946-07-25
Abstract: 624,440. Pulse delaying circuits. SADIRCARPENTIER. July 25, 1946, No. 22223. Convention date, Feb. 13, 1945. [Class 40 (vi)] In a pulse delaying circuit, pulses to be delayed from a source 1 synchronize a pulse generator 2 whose repetition period is a factor of the, desired delay and the repetition period of the original pulse, and also cause a resonant circuit 5 damped by a rectifier to ring and produce a half cycle of oscillation which is equal in period to the desired delay and thus blocks an octode 8 to which it is applied, together with the pulses from generator 2, until the desired delay time has elapsed. The first of the string of pulses which now appears at the anode of octode 8 is selected by passing the output through a phase reversing stage 13 and a stage 14 in which the first pulse charges a capacitor 17 in the cathode circuit to a peak voltage, rendering the stage insensitive to further pulses until the capacitor discharges through a parallel resistor 1, the time constant being equal to the original pulse repetition period. The output is taken off through a differentiating capacitor 18. A pentode or hexode may be substituted for the octode 8.

To ensure an even flow of granular material from a hopper to the rotor of a rotor-type electrostatic separator, an inclined feed plate 2 (Fig. 1, not shown) between the hopper 1 and the rotor 5 is vibrated in its own plane in a direction parallel to the rotor axis and transverse to the direction of flow over the plate. The amplitude of vibration is substantially equal to the average grain size of the material, typically from 0À3 to 6À0 mm., and the slope of the plate is preferably such that the tangent of its angle of inclination to the horizontal is from 75 to 90% of the tangent of the natural angle of repose of the material being fed. The preferred frequency of vibration is 3000 c./min., Fig. 2 (not shown), depicts a single hopper feeding two rotors by way of two such inclined plates. The surfaces of the inclined plates may have depressions designed to ensure that feed stops as soon as vibration is stopped: suitable profiles are depicted in Figs. 4 to 6 (not shown).

Abstract: 647,906. Turning. WARNER & SWASEY CO. Aug. 11, 1947, No. 22299. Convention date, Sept. 9, 1946. [Class 83 (iii)] Means for actuating the cross-slides of turret lathes and like machinetools comprise a movable member having a cam surface thereon, means for operatively connecting a movement-transmitting element with the cam surface to move the cross slide or tool-holder towards and away from the work, and disengaging means adapted to operate when the toolholder has returned to its initial position. The cross-slides 20, 21, are operated by levers 24, 33, respectively, the lower arms of which are forked to straddle a rotatable cam-carrying member 41, Fig. 2. The forked arms 30, 31 of the lever for the front crossslide are visible in this Figure. Bosses 57, 69, at the fork-ends carry slidable pins 58, 70, which are moved automatically into and out of engagement with cam paths provided on discs secured to the opposite faces of the member 41. The pins are engaged with the cam grooves by solenoid-operated linkwork moving a lever such as 61, Fig. 2, bearing against the end of the pin 59 which moves into a recess 60 in a block 38 in the disengaged position, and is retained therein by a spring-pressed ball. When the pin engages a cam-groove for operation of a cross-slide the face of block 38 or 39 prevents the pin from coming out of the groove as the fork-end oscillates. The member 41 is reversed to withdraw the cross-slides and wedge-pieces 49 are provided at the ends of the cam grooves 53, 54, Fig. 4, to cam the pins out of the grooves into the disengaged position when the cross-slides are completely withdrawn from the machine spindle. Switches such as 85, Fig. 2, are operated by projections on the periphery of the cam plates to prevent the actuation of the pins by manual switches until the projections have moved off the switches. The cam grooves may be of different configuration on the two plates, or, the second plate, 44, Fig. 4, may be circumferentially adjustable to give a different timing to the operation of a cross-slide relative to another part of the machine such as a turret slide. Safety-switches are employed for preventing the connection at the same time of the two pins common to one of the levers.
