Title: Commodity identification apparatus
IPC: G06K1/12
Filed: 1976-04-28
Abstract: 1506343 Label reader and printer HOBART CORP 28 April 1976 [30 April 1975] 17339/76 Heading G4M  A tag or label, e.g. for produce and meat, has a portion containing clocking perforations, three channels of data perforations (I, II, III) and a channel of parity perforations IV. The data perforations form six four-bit words as shown in Fig. 5 with the parity bit (71-76) for each word being shown in channel IV. Channel IV also contains two further bits 77, 78 which form a parity bit with the total number of perforations in channels I-III. The tag which also carries a humanly readable section (Fig. 1, not shown) is inserted into an optical reader having a photocell for each of the four data and one clock channels and a further photo-cell responsive to a slit or notch in the tag. to reset appropriate electronics in the reader. Signals from the photo-cells corresponding to channels I to III are fed to a multiplexer 26 which supplies data to a recirculating register formed by 8-bit shift register 27 and 16-bit shift register 23. The parity channel is fed to storage register 25. The clock pulses feed registers 23, 27, 25 and a binary counter 33. The counter is reset when the slit or notch in the tag is read. Parity checking is performed under the control of program counter 31 and clock oscillator 24. The first four bits of Channel I are read by a multiplexer 29 from register 27 decoded to a 1 out of 10 signal and fed to a bar code printer. The data is shifted to read out the second four bits of channel I. This process is repeated to read all six stored words. Data from register 27 is also fed to Exclusive OR gates 58 which feed Exclusive OR gate 59 to produce a "1" if an odd number of "1"s exist. Parity data is fed from register 25 to multiplexer 32 which feeds Exclusive OR gate 56 also receiving the output of gate 59. Gate 56 thus produces a "1" for each correct parity check. Gate 56 feeds counter 36 which clocks flip-flop 41 after a count of 6. Exclusive OR gate 60 performs the parity check for all six words. If the parity checks are correct flip-flop 41 produces a signal allowing the data to be printed. If a check does not agree printing is prevented and the tag or label must be pulled from the reader and replaced before further printing is possible.

Title: Paper pile aligner for automatic cutter
IPC: B26D7/32
Filed: 1963-05-02
Abstract: 1,024,297. Paper cutting machines. MIEHLE-GOSS-DEXTER Inc. May 2, 1963 [May 2, 1962], No. 17388/63. Heading B4B. A paper - cutting machine comprises a knife 14, clamp 18, and a bar 44 which is engageable with paper pile 40 to be cut for the purpose of aligning the pile. As described, the bar 44 is arranged to align the forward face of the paper pile which is squared up between the front of a backgauge 22 and the aligning bar 44. The bar 44 is guided by a pivotal parallel linkage 52 secured to support blocks 57 so that it can move to and from the pile under the influence of springs 48 or by means of a rod 59 and a pneumatic piston- and-cylinder 60, 62. Each support block 57 is carried by a rod 66 adjustable vertically by a stop-nut N and actuatable by a piston 68 in a pneumatic cylinder 70, which is secured to a respective horizontal support rod 72 slidably supported in bores 76 in the frame. Each rod is biased by springs 80 for movement to the right, and passes through a rear support-bore 84 in a support 88 bolted to the back gauge 22. A respective spring-biased latch 94 is pivotally carried by each support 88, and normally locks against each rod 72 to lock the bar 44 to the back-gauge so that they move in unison. Each upright 88 carries a solenoidplunger device 98 which trips the latch 94 to free the bars 72. In the operation of making a cut, the cycle starts with the bar 44 in the position shown in which it aligns the pile against the back gauge 22. The clamp 18 is then arranged to apply pressure to the pile just prior to the cutting stroke of the knife and when the clamping pressure builds up to a predetermined extent a switch in the control system releases the latches 94 to permit the springs 80 to move the cylinders 70 forwardly against the machine frame and simultaneously the pneumatic feed to the cylinders 62, 70 lifts and withdraws the bar 44 out of the path of the paper section 102 to be cut off; the knife movement is responsive to a predetermined clamp pressure in order to ensure proper clamping before cutting. At the end of the cutting stroke, the conveyers 30 are actuated to carry away the cut-off section 102 by a switch operated by a cam rotating with the knife crank. When the knife reaches its upper position a knife-crank cam operates a switch and solenoid to release air-pressure from the cylinders 62, 70 to permit the alignment bar 44 to drop at a controlled rate into a pileengaging position and the drop in clamping pressure actuates the pressure switch in the control system to cause the latches 94 to lock the bar 44 and rods 72 to the back gauge to recommence the cycle.

Abstract: 718,320. Controllers. BENCHEMOUL, N. R. July 14, 1952 [Aug. 7, 1951], No. 17693/52. Drawings to Specification. Class 38(3) [Also in Groups XI and XXXVI] A liquid resistor wherein liquid evaporation occurs between electrodes (see Group XXXVI) is used as an automatic starting and control rheostat in an induction motor control system. At starting when the full voltage is applied to the stator of the motor the liquid rheostat receives a high rotor voltage and this produces evaporation and the insertion of high vapour resistance m series with the rotor. As the rotor voltage declines the vapour between the electrodes is replaced by liquid and the resistance decreases and when the rotor voltage becomes very low the amount of resistance in series with the rotor may be regarded as negligible. If desired, the rheostat may be short-circuited by automatic means which also functions to re-insert the rheostat in the event of excessive opposing torque to thereby produce an automatic increase of the rotor resistance.
