Title: Automatic + X-Axis Detector, Marker, Sorter and Collector for Crystal Wafer Blanks
Inventor: BIRRELL ROBERT
IPC: G01J1/12
Filed: 1967-02-15
Abstract: 1,151,271. Shoots. AIKEN INDUSTRIES Inc. 15 Feb., 1967, No. 7301/67. Heading B8S. [Also in Division G1] The + X-axis of quartz crystal wafer blanks is detected photo-electrically using polarized light in order that the crystals may be collected together in the same orientation. In one arrangement, Figs. 3 and 4, in which the crystals are sorted and collected into four groups of different + X-axis orientation, the individual crystals are marked to indicate the +X-axis orientation. A crystal CW arrives at the window 70 of the detection station and is held there by a solenoid-operated finger 74 while the - X-axis orientation is detected. This is done by use of a system (shown diagrammatically in Fig. 4) including a light source 188 directing light on to four mirrors 190 so that four light beams are passed through the corners of the crystal CW from beneath the latter. Four pairs of photo-resistive cells 212a-212d are arranged to receive the respective light beams through polarizers. The pairs of cells are connected in a bridge network forming part of the control circuit 214 (detailed in Fig. 13, not shown). Unbalance of the bridge can occur in four ways to cause energization and/or non- energization of solenoids 92 and 106 through SCR's and a timing circuit including a relaxation oscillator for delay purposes, in four different combinations causing actuation and/or non-actuation of blade members 90, and 102 and 104. Thus a crystal CW can be directed into an appropriate branch 62, 64, 66 or 68 (formed as grooves in the sloping board 24). Amotor 136 continuously drives a shaft 133 which, through cams, Figs. 5-7 (not shown), causes stop fingers (156) to be raised periodically in grooves 62-68 to stop any crystal to allow a marker assembly 140 to mark the crystal with the appropriate + X-axis orientation indication, and also causes a crystal, on arrival at the bottom of a groove, to be fed into a magazine 52. When full, a magazine, Figs. 9-12 (not shown), is removed by unscrewing screws 130. An arrangement is also described, Fig. 16 (not shown), in which the grooves in the sloping board are specially shaped to cause rotation, through 90 or 180 degrees, of some of the crystals after release from the detection station, so as to arrange all the crystals in a single + X- axis orientation direction at a single collector station. An arrangement in which there is only a single guide path for blanks, from detection station to collector station, Fig. 17 (not shown), uses a turn-table controlled in accordance with the detector circuit output, to rotate crystals as required so as to all be similarly +X-axis orientated. Instead of using a plurality of light beams in the photo-electric system, a single polarized beam may be used, the crystal being rotated during detection.

Abstract: 1,014,674. Book trimming machines. R. D. H. THOMPSON & CO. Ltd. Feb. 25, 1963 [Nov. 23, 1961], No. 7558/63. Divided out of 1,014,671. Heading B4B. A machine for trimming piles of paper sheets or books comprises a knife formed of two parallel blades 2 adapted to define two opposite cut edges of the piles of books, a face-plate 11, a ram 12, and means 13 to remove a cut pile or book, the ram and either the face-plate or the knife being reciprocable in the direction of cut, so that when the piles or books are fed in turn to the face-plate one pile or book is only partially cut, as the knife remains spaced from the face-plate, and this pile or book is held between the blades while a further pile or book is fed into the machine. The knife comprises two parallel blades 3 and a third blade 5 set back from the blades 3. In operation, a book 14a rests against the face-plate 11 and a book 14c is ejected by the pusher 13. The face-plate 11 is moved until the book 14b which was previously partially cut by the blades 3 bears against the book 14a and the ram 12 is then moved against the books 14d and the pile of books compressed. The face-plate 11 is then moved under high pressure towards the knife assembly so that the blades 3 partially cut through the book 14a and complete the cutting of the book 14b, the blade 5 also cutting on the third side of the latter book. When the face-plate 11 has reached the end of its stroke the ram 12 is withdrawn and the face-plate 11 is moved away from the knife which retains the book 14a; a further book is placed between the book 14a and the face-plate, and the book 14d is ejected by the pusher. The cutting edge 5 is curved at its ends to permit cutting of rounded corners.

Title: Improvements in or relating to automatic feed apparatus
IPC: G01G13/00
Filed: 1950-03-28
Abstract: 729,633. Automatic feed weighers. LINDARS, H. March 19, 1951 [March 28, 1950; Nov. 13, 1950], Nos. 7784/50 and 27707/50. Class 143. [Also in Group XXIX] An apparatus for feeding material at a desired mean rate comprises an automatic feed weigher the weighing receptacle of which is discharged by a timing mechanism. As shown in Fig. 2 a timing mechanism which is described in Specification 729,632, [Group XXXVIII], is adapted to start a motor 14 and rotate a double compartmented receptacle 10 through 180 degrees after contacts 17 have been opened by the weigh beam at the completion of a weighing operation, and after an interval of time, determined by the setting of an adjustable contact 26, has elapsed after the last discharge operation. In. the event of the contacts 17 not being opened before this time interval has. elapsed, the timing and discharging mechanisms are immobilized and an alarm indicator S operates. Material is fed from a hopper 1 onto a continuously rotating circular plate 3 from which it is swept into the receptacle 10 by a strickle 4. On the initial movement of the beam, effected by both the weight of a partly completed charge and a spring device 45 which temporarily accelerates movement of the beam, a pair of contacts 44 open and de-energize an electro hydraulic valve 41 which allows a piston 39 of a thruster 38 to move downwardly under the action of a spring 33 and, through gearing 32, to pivot the strickle 4 towards the edge of the plate 3. This effects a dribble feed, at the end of which contacts 17 are opened so de-energizing a second valve 40, and through a second thruster 36, in tandem with thruster 38, allowing the strickle to pivot clear of the plate 3 to effect final cut off. In a modification (not shown) the thrusters 36, 38 are double acting, and.spring 33 is dispensed with. A weight 15 on the beam, which can be moved therealong to adjust the weight of each charge, is automatically controlled from a remote station by the mechanism in Specification 729,636. In a modification (Fig 1, not shown) pivoting of the strickle is effected by.a solenoid, the beam loading device 45 and contacts 44 being dispensed with so that no dribble feed is provided. In another modification (Fig. 3, not shown) the strickle and plate feed is replaced by a motor controlled valve at the base of hopper 1. In further modifications the timing mechanism may be replaced by that described in Specification 566,911, [Group XXXVII], the strickle may be operated by a "Selsyn" system, the transmitter' of which is coupled to the weigh beam, and the receptacle 10 may rotate about an axis parallel with the longitudinal axis of the beam,

IPC: H02P1/04
Filed: 1920-03-17
Abstract: 144,612. Tritle, J. F. June 6, 1919, [Convention date]. Master-control systems; for continuous-current motors only.-A system of master control includes a current-limit device for causing a stepby-step advance of a controller under the influence of the motor current, and manually controlled means for causing the controller to begin a step independently of the current limit device and to prevent further movement after completion of the step until the operator restores control to the current limit device. The general arrangement of the system shown and the methods of operation of the reverser RS, line switches LB, LB<1> and motor controller M are similar to those described in Specification 110,246. The throttle relay D has a coil 57 carrying the motor current, and a shunt coil 56; these two coils assist to attract the armature 69 against the pull of the spring 70 to break circuit at the contacts 58. A separate core carries the coils 60, 67; the latter attracts an armature 65 to break the contacts 66 and the former attracts an armature 61 with hook 64 which engages an extension of the armature 69 to complete a short circuit round the contacts 58 by a path through contacts 66, armature 65, frame 75, armature 61, hook 64, and extension 62. The motor used to operate the controller M may be of the pneumatic type described in Specification 11658/15. During operation connexions are made for series-parallel control subject to control by the throttle relay, but if the motor controller M starts to take a step, that step will be completed even if the throttle relay opens, as the circuit for the ' off ' magnet 29 is completed through one of the contacts G. When the current is large enough to operate the throttle relay the circuit of the ' off ' magnet is broken at the contacts 58 and the operation of the controller M is stopped. The operator may then close the normally open push bottom 59 to energize the coil 60 of the relay D from the battery. The armature 61 is then operated to short-circuit the contacts 58. This closes the circuite for the ' off ' magnet 29 and enables the pneumatic motor to move the controller M one step forward. At the end of the step, control must be restored to the current limit throttle by releasing the push button 59 since the flux due to the coil 60 will retain the armature 65 in its attracted position. Another step can then be obtained by again depressing the button 59. The arrangement therefore provides for full automatic control, or full manual control, the controller being advanced step-bystep by depressing and then releasing the push button 59.
