Title: Envelope making apparatus
IPC: B31B150/00
Filed: 1971-12-07
Abstract: 1369457 Envelope making machines WINKLER & DUNNEBIER MASCHINENFABRIK UND EISENGIESSEREI KG 7 Dec 1971 [9 Dec 1970] 56835/71 Heading B5D [Also in Division F2] To facilitate the adjustment of various mechanisms that operate on an envelope blank as it travels through an envelope making machine so that the machine can be pre-set to produce envelopes of different sizes the mechanisms are adjusted by hydraulic actuators operated by remote control in accordance with a comparison between a signal corresponding to a desired dimensional characteristic and an appropriate feedback signal received from the adjusted mechanism. The adjustment may be semiautomatic using manually adjustable set value potentiometers or digital preselectors together with push buttons for initiating adjustment; alternatively a fully automatic system employing electronic control and having the dimensional requirements and sequence of adjusting steps on punched card or tape or on magnetic tape may be incorporated. Adjustments are made to the following parameters envelope height, width, flap construction, size and position of window, also to variations of speed of the envelopes through the machine. The envelopes are fed from a stack 1 and a pass in sequence to a printing station 2, window cutting 3, adhesive supply 4 and windows positioning stations 5. At station 6 a staggered stack is formed and the flaps have adhesive supplied thereto at 7. At station 9 the adhesive is dried. At 11 the blanks are separated and at 13, 14 longitudinal and transverse folds are formed and subsequently at stations 15-18 the flaps are folded and adhesive supplied. Finally, finished envelopes are collected at 19.  Adjustments concerning width are made while the machine is running but any adjustment relating to the height of the envelope or window are made when the machine is stationary. The hydraulic system consists of an electrically driven pump drawing fluid from a sump, a pressure control valve and filter and flow and return lines; an accumulator may be provided. The machine has a control panel carrying a setvalue potentiometer and push button switches and tell-tale lamps. The lamps are marked + and - and the appropriately lit lamps indicates if that particular dimension is greater or less than the required dimension. Photo-cells detect any jam-up on the machine.

Title: Apparatus for detect phase encoded data being read from a data storage subsystem
IPC: G11B20/14
Filed: 1973-12-07
Abstract: 1451202 Data storage systems HONEYWELL INFORMATION SYSTEMS Inc 7 Dec 1973 [9 March 1973] 56933/73 Heading G4C The preamble to a block of data read from a magnetic tape or disc is detected by a circuit (Fig. 1, not shown) comprising a reversible counter fed with signals from two gating means. The gating means receive signals derived from the read head and from a clock pulse generator. The preamble signals fed to an input (18) of the circuit are as at A, Fig. 2. Other inputs (19, 17) receive clock pulse signals B, C. A pair of JK bistables (11, 12) responds to A and C to cause a NOR gate (29) to provide a signal D which becomes high when the first of the preamble pulses is detected. A second pair of JK bistables (13, 14) receives A and D and causes a NAND gate (30) to provide a signal E which becomes high when the third preamble pulse is detected. A first NAND gate (31) receives the signals A and E and feeds preamble pulses F subsequent to the third to the up-counting terminal of the counter (37, 38). The counter feeds a NAND gate (33) which, when a certain number of pulses has been counted, provides signal to set an output bistable (40), giving an output J. When pulses A no longer appear at the circuit input the bistable pairs cause signals D and E to become low. When D is low a second NAND gate (32) receiving clock pulses B provides an output G to the down-counting input of the counter. When the count has reverted to zero the output bistable is reset, so that J becomes low.

Title: Circuit arrangement for a voltage converter
IPC: H02M3/10
Filed: 1971-12-10
Abstract: 1381732 Converting MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 10 Dec 1971 [13 Dec 1970] 57382/71 Heading H2F Cathode-ray tube apparatus comprises means D1 . . . D4 for rectifying A.C. power and means, such as T1, T2, for regulating the resulting D.C. power for supply to the deflection circuits (not shown) of said CRT in accordance with a signal dependent on the beam current of the CRT. As shown in Fig. 6, the A.C. input is rectified by diodes D1 ... D4 and controlled by a series regulating transistor T1 in dependence on the difference between an adjustable voltage at the tapping of a potential divider R3 ... R5 across the D.C. output and a reference voltage across a Zener diode ZD. A connection is made at the junction of the video amplifier and cathode of the CRT so as to compensate for changes in CRT beam current. In Fig. 4 (not shown) the beam current compensating signal is obtained from a parallel RC circuit in series with the low potential end of the EHT secondary winding. The upper end of resistor R4 is connected to the collector of transistor T2 so that the D.C. output voltage is no longer monitored. Thyristor regulating circuits.-In Fig. 7, the output of rectifier 110 is chopped by thyristor 118 and filtered at 122 to provide the required D.C. output at 126. A sawtooth wave is generated at 130 and a pulse generated at 134 when the sawtooth wave crosses a reference voltage determined by the D.C. output and beam current, so that a trigger pulse is generated at 148 so as to provide the required conduction angle for thyristor 118. Figs. 8 and 9 (not shown) depict circuit diagrams of the system shown in Fig. 7.

Patent GB-701905-A (GB)
Abstract: 701,905. Calculating-apparatus. OCHSNER, C. Aug. 18, 1950, No. 20567/50. Class 106 (1) A carrier supporting and driving the differential setting racks of a calculating machine maintains the racks engaged with totalizer setting wheels during the forward movement and disengaged on the return, transfer pawls then engaging the wheels to effect transfer and secure the wheels in adjusted positions. Differential setting meohanism. - In the machine shown, a set of slides 8 are moved rearwardly by a cross bar 9 working in guide slots 10 upon a downward movement of an operating handle 13. Differential racks 7 are picked up successively by spring pawls 70 on the slides engaging notches 72 in the racks, and the racks are arrested in differentially-set positions by engagement of lugs 7b thereon with the stems of depressed keys. In an order where no key is depressed, a zero stop 62 remains engaged with a lug 7b to prevent movement of the rack. An ordinal key detent bar 58 (Fig. 15), tripped by a depressed key, swings the stop clear and the stop is retained clear by engagement of the detent tooth of the key with an angle bar 59 carrying the stop. The racks 7 engage totalizer setting wheels 29 alternatively engaged by add/subtract pinions 55, 56 of the totalizer. As the cross-bar 9 reaches the limit of its rearward movement, it abuts arms 21 and connected cam plates 18 are rocked counterclockwise, cam slots 17 in the plates lowering a rear guide bar 15 for the racks 7 and bars 8 so as to disengage the racks from the wheels 29 during their return movement. Transfer mechanism.-The downward movement of the bar 15 also rocks a pair of bellcranks 24 clockwise to engage a set of transfer pawls 28 with the wheels 29, the pawls being slidable, by means of short vertical slots, on a rod 26 between the bell-cranks and a fixed rod 32. Transfer is initiated by a pin on the lower totalizer wheel engaging a finger 50 on a transfer lever 40 and rocking the transfer lever to release a bell-crank 39 on the transfer pawl 28 to the action of a spring 45, so that the upper arm of the bell-crank engages under an actuater arm 41. As the bars 8 return, cam elements (not shown) on their lower edges momentarily depress the actuater arms 41, and lower those transfer pawls 48 whose bell-cranks 39 are engaged with the arms to impart an additional step to the associated totalizer wheels 29. The pawls 28 are retained in lowered position by spring- actuated catches 35 until the bars 8 and racks complete their return movement, whereupon the bar 9 abuts and restores the cam plates 18 which re-engages the racks 7 with and disengages the pawls 28 from the wheels 29, the pawls 28 then clearing the catches 35 and returning under spring action.
