IPC: B65B7/28
Filed: 1969-07-21
Abstract: 1,233,673. Packaging machines/endless conveyers for trays. DIAMOND INTERNATIONAL CORP. 21 July, 1969 [23 Aug., 1968], No. 36606/69. Headings B8A and B8C. In a packaging machine, filled trays 40<SP>1</SP> are fed by an intermittently driven conveyer 104 to a position below a planar cap blank 1211 fed from a magazine 106 by a transport mechanism, and are intermittently raised by an elevator 105 so that a tray 40<SP>1</SP> contacts a cap blank 12<SP>11</SP> and both are passed through a package assembly means 110 where the blank 1211 is erected to a faceted, three dimensional configuration and glued to the tray 40<SP>1</SP>. Formed packages are ejected from the machine on a conveyer 240. Package assembly means.-This means 110 comprises a plurality of spring urged plates 232 which down fold the edges of a blank 12<SP>11</SP> and press them against the sides of a tray 40<SP>1</SP>. Tray conveyer.-The filled trays 40<SP>1</SP> rest on a frame 118 and are engaged by pushers 114 carried by endless chains 112 (only one shown). A motor 124 drives a timing shaft 302 which rigidly supports a lever 304, the motor 124 being connected to the timing shaft 302 via an electric clutch 125 and chains 122, 123. The lever 304 is connected to one end of a chain 322 the other end of which is meshed with a toothed wheel 312 freely rotatable on a shaft 308. The shaft has keyed thereon a sprocket 310 in driving engagement with the chains 112, and a drive member 316 having diametrically opposed notches 318 into which a dog 314 pivoted to the toothed wheel 312 is spring urged. During clockwise rotation of the lever the dog 314 rotates the drive member 316, and hence the sprocket 31, counter clockwise, thus advancing the chains 112 to the right. During this rotation a coil spring 320 attached to the toothed wheel 312 is tensioned and, when the lever has rotated through 90 degrees, this spring 320 rotates the toothed wheel counter clockwise, the dog 314 slipping over the drive member 316. The elevator 105.-A chain 128 having tray support members 134 is driven by a sprocket 130 connected to the lever 304 by a linkage similar to that interconnecting the lever 304 and the sprocket 310. Thus, when chains 112 are driven the chain 128 is stationary and vice versa. Cap blank transporter.-The shaft 302 also supports a lever 166 (Fig. 1) acting on a lever 156 to cause a suction cup 182 at the free end of a tube 180 to grip a cap blank 12<SP>11</SP> and transfers it to the index position. A cam track 188 guides a roller 186 secured to the tube 180. Applying adhesive to the cap blank.-A cam 205 on the shaft 302 causes fingers 200 to dip into a glue pot 198 and then apply the glue to the edges of the blank 12<SP>11</SP>. Completed packages.-Each cap blank 12<SP>11</SP> has an octagonal central aperture 14 covered by transparent material 20, and fold lines 22 adjacent each corner of the aperture to define triangular areas 24 and polygonal areas 26.

Abstract: 1,257,125. Automatic exchange systems. SIEMENS A.G. 1 Oct., 1969 [2 Oct., 1968], No. 48142/69. Heading H4K. In a TDM system having 4-wire highways between exchanges, the time frames on all the incoming pairs to any one exchange are synchronized to each other as also are the frames on all the outgoing pairs, the latter frames being delayed by a period tv relative to the incoming ones. Time slot interchange is effected by ensuring that the time slots of a same channel on the incoming and outgoing pairs in one highway are relatively delayed by n.tv (n = integer) whereas those for the corresponding channel on the associated highway in the required direction are in phase. In Fig. 1 mutual synchronization of the incoming pair Aan1, Aan2 to exchange A is effected by delay devices Vab and Vac, the other incoming pairs and the outgoing pairs being similarly synchronized by devices not shown. In Fig. 2a it can be seen that a time frame T on incoming pairs Aan1, Aan2 leads the corresponding frame on outgoing pairs Aab2, Aab 1 by a time tv. It can be further seen that the time slot (single pulse on Aan1) utilized by a PCM channel between B and A leads the corresponding time slot (single pulse on Aab1) utilized by the same channel between A and B by a time 2tv. In the highway between A and C the associated channel utilizes synchronous time slots in both directions (aligned pulses on Aab2, Aan2). It will be noted that in fact the same numbered time slot is used by this channel on all the pairs in this embodiment. For the limited number of cases where the above relationship cannot be maintained, the stores used for effecting the necessary delays may have a total delay time of T + 2tv instead of merely 2tv (Fig. 2b, not shown).

Abstract: 1,257,457. Leaf turners. K. N. KASTOMJEE. 20 April, 1970 [7 May, 1969],No. 18740/70. Heading G5X. A leaf turner comprises a plurality of strips C for insertion between the pages of a book placed on the stand E and an arm A which has a substantially flat end B which on anticlockwise movement of the arm slides under the top page to turn it. The arm is rotated by a foot-controlled Bowden cable K or by electric, pneumatic or hydraulic means. On release of the foot control, the arm A swings back under the action of a spring I and a hook B1, Fig. 4, on the flat end B pulls down the uppermost strip C to release the next page for turning. The strips C are mounted on a screw CC, Fig. 4, and separated by washers W. A spring provides sufficient friction to prevent undesired movement of the strips C.

Abstract: 1295566 Transponders MOTOROLA Inc 19 April 1971 [2 March 1970] 24891/71 Heading H4L In a transponder of the type which may be carried on the person to transmit a coded identification signal on the receipt of an interrogation signal, received pulses are amplified at 14 and supplied to processing circuits 16 which produce reply pulses with adjustable spacing which are supplied to the radio transmitter 18. A lamp 20 indicates when the transmitter is operating. Power is supplied from a battery via a voltage regulator 22, a stand-by gate 24, which is opened only when a signal is received, controlling the supply to the transmitter and lamp. In the processing circuit 16, Fig. 3, a multivibrator 44 converts the received pulse into a relatively long negative-going pulse 200, Fig. 5, of predetermined duration and amplitude, so that if another pulse is received before the end of the long pulse the multivibrator will not respond. The response pulse from the transmitter 18, which could be coupled via R.F. circuit 10 to the amplifier 14 also will have no effect on the multivibrator 44. The duration of the pulse from multivibrator 44 is equal to the reciprocal of the safe pulse rate of the transmitter 18 to prevent overloading. Pulse 200 is fed via a timing circuit 52 to a modified OR gate 50, producing pulse 204 from its leading edge. Pulse 200 is also supplied to a pulse space generator 46 producing pulse 202 of adjustable duration, which via timing circuit 54 and OR gate 50 produces pulse 206 from its trailing edge. The output of the OR gate 50 is supplied to a modulator 56 which from the trailing edges of pulses 204, 206 produces standard pulses 212, 214, of spacing determined by the duration of pulse 202, for transmission as the response signal. This arrangement provides all the functions of a known arrangement, Fig. 2 (not shown), in a simplified manner, making the equipment more compact. Details of the transistor circuitry are given, Fig. 4 (not shown).
