Title: Flow regulator for a duct
IPC: F24F11/75
Filed: 1975-10-07
Abstract: 1518192 Valves E SIEGWART 7 Oct 1975 [10 Oct 1974] 40954/75 Addition to 1465330 Heading F2V [Also in Division F4] A flow regulator for ducting, similar to the air duct regulator described in Parent Specification 1,465,330, has an angled flap 4 which is turned by the flow in the ducting against a spring 15 to close the free cross-section of the duct. The spring acts on the flap lever arm 9 at a point 8, which point describes a circular arc 16 on rotation of the flap from the open position to the closed position. The tangent to the arc at point 8 with the flap in the open position is at a larger angle relative to the direction of the spring force than it is with the flap in the closed position. The torque on the flap thus increases out of proportion with the turning of the flap. The spring 15 may be helical and mounted on a rod 14 by means of a pin 13. The rod is attached to a cap 12 which screws on a tube connector 11, and the regulator is adjusted by turning the cap 12 so that the rod 14 is screwed into or out of the helical spring 15 to alter the effective length of the spring. A metal plate 10 limits the open position of the flap and aids the smooth operation of the device. In a further embodiment the regulator may be adjusted by a diaphragm control device (19), Fig. 5 (not shown), which can also positively move the flap to the closed position.

Abstract: 1359314 Flying shears MOELLER & NEUMANN GmbH 9 Sept 1971 [24 Sept 1970] 42155/71 Heading B3W A flying shear for trimming or slitting metal sheet comprises an elongated upper and lower cutter extending parallel to the sheet feed direction, the upper or each cutter carrier being connected at the sheet exit end to a continuously driven crank and at the other end to a rocker, the rocker being longer than the crank and being pivotable in the sheet feed direction through less than half a revolution, during a complete rotation of the crank, between positions each corresponding to a dead point position of the crank. The crank bearing point is closer to the feed plane of the sheet than the rocker pivot point is and the upper, or each, cutter carrier together with its crank, rocker and crank drive constituting a crank rocker drive for oscillating the respective cutter to shear the sheet. As shown, Fig. 1, an upper cutter carrier 10 is connected to a continuously rotating crank 20 at the sheet exit and to a rocker member 14 at the sheet entry end, the rocker member being longer than the crank radius 20 and the crank bearing 28 being closer to the plane of sheet feed than the pivot point of member 14. During a cutting stroke the cutter carrier travels in a circular path only near the crank, the other end of the carrier moving in a substantially translatory manner. The lower cutter may be similar to the upper cutter (Figs. 2-7, not shown) or be mounted on a table 15 running on rollers 17 in the feed direction and being retracted by an hydraulic cylinder 18. The movement of the table in the feed direction can be overridden by the variable feed speed imposed on the sheet by the cutters between which it is clamped during a cut. If uniform feed speed of the sheet is necessary as in edge trimming, Fig. 8 (not shown), an eccentric crank drive (Figs. 9, 10, not shown) converts the sinusoidally changing horizontal speed of the crank-pin into a uniform speed at least over the rotary angle during which cutting takes place. The cut starts at the exit end of the sheet and continues just past point 11a. Edge strips may be cut up by further flying or rotary shears or by transverse cutters mounted on the flying trimming shears at the exit end.

Abstract: 425,968. Coin-freed apparatus for franking letters. HACKL, (nee MAUL), M., 12, Badstrasse, Nuremberg, Germany. June 20, 1933, No. 17558. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 14, 1934]. [Classes 27 and 143] A letter B, Fig. 1, is inserted through a slot 2 in a letter-box 1 to a rockable receptacle 6 where it is retained by a pivoted plate 8 controlled by a spring 9. The weight of the letter rocks the receptacle 6 which, through a lever 10, tilts a weighbeam 4 pivoted at 3 and provided with a quadrant scale 5 to indicate the weight of the letter in conjunction with a fixed pointer 47. The weighbeam has articulated to it two shutters 12, 13 which normally close two coin slots 14, 15 respectively, the shutters having cam slots 19, 20 engaging fixed pins 21, 22. If the letter is below 20 grammes in weight, the movement of the beam is sufficient to uncover slot 14 only, but if it is above that weight, the slot 15 alone is uncovered. Franking fees of 12 and 25 Pfennigs must be inserted in the slots 14, 15 respectively. These coins pass to a testing device 18 and tilt a lever 32 to slide one member 25 of a clutch 26 into engagement with the other member 28, the members 25, 28 being carried respectively by a tubular shaft 24 and by a spindle 29 passing through it and rotatable by a handle 31. The shaft 24 carries a cam 37 which allows a lever 36 to be actuated by a spring 44 to cause a franking stamp 34 to be pressed against the letter B. A second cam 46 by engaging an arm 45 opens the plate 8 of the receptacle 6 and allows the stamped letter to fall into the box 1. A pin 27 engaging a groove 25<a> in the clutch member 25 disengages the clutch at the end of one revolution of the spindle 29. The franking stamp comprises a fixed disc to give the name and number of the district postoffice, and four rotatable discs to indicate the time the letters are collected, the day, the month, and the year respectively. It is set by hand each time the box is cleared, but an automatic time-setting device may be employed.

Abstract: 1,022,296. Titration control apparatus. METRIMPEX MAGYAR MUSZERIPARI KULKERESKEDELMI VALLALAT. Nov. 12, 1962, No. 42662/62. Heading G1N. A potentiometric titration system comprises a circuit having three successive resistancecapacity differentiation stages, to the input of which signals from the cell electrodes are fed and from the output of which a signal is generated and applied to a further circuit to terminate the supply of titrant at the occurrence of a signal due to the third derivative of the titration inflexion point. As shown in the Fig, a signal enters the first differentiation stage comprising elements C 1  and R 1  from terminals G and R from the indicating and reference electrodes. Valve V 1  counteracts the damping effect of the differentiating elements. Second and third stages similarly comprise elements C 2 , C 3 , R 2 , R 3 , and V 2 , V 3 . A further valve V 4  is biased so as to cut off when a negative signal appears in the output of the third stage so that the coil of relay Rel. 2 having a self-holding contact is de-energized and the coil of relay Rel. 1 is energized, thus opening a switch in circuit K. This circuit controls a titrating valve so that when the circuit is opened, the valve is shut off and the result of the titration may be read. It is stated that the input from the electrodes may alternatively be fed into a symmetrically balanced amplifier. The use of these systems obviates errors arising from the time lag resulting from electrode polarization.

Title: Automatic voting machines
IPC: H01Q11/08
Filed: 1973-09-11
Abstract: 1422260 Voting apparatus AVM CORP 11 Sept 1973 [23 March 1973] 42750/73 Heading G4T [Also in Division H1] An electronic voting machine includes a matrix array of selectively operable switches, each of which is associated with a particular one of a number of possible votes that can be made, a matrix array of counters, each associated with a particular switch, a clock for cyclically pulsing input terminals of the switch, and logic circuitry connected between the counters and the output terminals of the switches so as to sense transmission of a pulse through any switch which has been actuated by the voter and to actuate the corresponding counter(s). As shown in Fig. 2, clock 62 delivers non- overlapping pulses on lines 80, 82, 84 in a repeated sequence. These lines are the column lines of a 3 x 3 matrix of switches 86-102. The pulses on any one of the column lines are also delivered to three indicator lights L and three counters C, associated respectively with the three switches of that column. When a switch is closed, a pulse is transmitted to logic 156 on line 109, 110 or 112, depending upon the row in which the switch is located, and at a time in the clock pulsing cycle indicative of the column in which the switch is located. During the first part of the voting operation (when the vote is actually being made), logic 156 enables gates S, so that lights L indicate any vote(s) made. A voting-official-controlled switch 104, depressed to admit a voter to the machine facilities, has conditioned the machine for this type of functioning. On completing his vote, the voter closes switch 106, which causes logic 156 to enable gates R, the vote thus being recorded in the appropriate counters C. Logic 156 may enable the various gates only if certain voting conditions have been satisfied. The logic may, for example, check that a single vote has been cast in each of two elections, for presidential and congressional candidates respectively. For this purpose, each switch, Figs. 19-23 (not shown), may be manually pre-set by the voting official to one of two positions, in which the input line will be connected to a respective one of two output lines upon depression of the switch actuating button. The switches are programmed in this way before the election to divide the array of switches into two areas, for presidential and congressional elections respectively. The logic is then in two parts, connected respectively to the presidential and congressional output lines from the switches. The Specification discloses in detail the circuitry of and the logical functions performed by the machine.
