Abstract: 1,257,066. Digital/analogue converters. INTERNATIONAL BUSINESS MACHINES CORP. 15 Oct., 1969 [21 Nov., 1968], No. 50564/69. Heading G4H. In a digital/analogue converter the count in a counter pulsed from a clock source is compared with a digital input signal, a pulse being generated at equality of the two signals and at a predetermined count of the counter to generate a signal the width of which represents the digital input. In the embodiment of Fig. 1 when a digital signal D is read into a buffer store 40, gate 88 is enabled to apply clock pulses to counter 42 of capacity 2<SP>n+1</SP>. The signal D and its complement D<SP>1</SP> are compared with the count in counter 42. At equality of the signal D and the lowest n bits of the count bi-stable 50 is enabled so that the output from a switch 62 changes from +V to - V. At equality of signal D and the count bi-stable 54 is enabled so that the output of a switch 72 changes from - V to + V. The switch outputs are applied to a summer connected to a filter the summer output being a pulse of Œ2V in accordance with whether the input is less than or greater than 2<SP>n-1</SP>, the width of the pulse being proportional to D. When the lowest n bits of counter 42 are all "1" the bi-stables are reset to change-over the switches. With the most significant bit of the counter equal to "1" the process is repeated so that a second pulse width signal is obtained. At full count of the counter the gate 88 is closed. The counter may have n+k stages so that the pulse width signal is repeated k + 1 times. In a synchronous modification of the embodiment of Fig. 1 (Fig. 3, not shown), the clock controls the reading-in of data and the gate controlling the application of pulses to the counter. The two comparators (144, 146) control bi-stables (150, 154) such that the first is set for a time D and the second is set for a time D. The set output of the first bi-stable (150) is fed via an AND gate (174) (closed for the second half-cycle of the counter by the (n+1)th stage) to an OR gate 182 which when in its "1" state operates a switch 186 to apply a signal - V to a filter 190. The OR gate also has an input from an AND gate 166 enabled only during the second half-cycle of the counter by the reset output of gate 154. This results in a voltage of +V for a time D followed by a voltage of - V for a time 2D and then a voltage of + V for a time D being applied to the output lead 192 during one cycle of the counter. As in the modification of Fig. 1 the counter may have (n+k) stages where k is odd.

Abstract: 1,265,101. Strap tensioning tools. PAUL HELLERMANN G.m.b.H. 16 April, 1970 [17 April, 1969], No. 18127/70. Heading F2G. A strap tensioning, connecting and cutting tool comprises a handlever 4 disengageably coupled to operate a tensioning and gripping means 11: while the coupling engages, the range of travel of the handlever is restricted by a stop 27, but at a predetermined tension in the tape 8 the coupling automatically disengages at 15, 17, the stop is no longer effective and the handlever may move beyond the restricted portion of its range of travel to actuate a locking arrangement 6, 9 to connect the tape ends and thereafter a blade (35), Fig. 4 (not shown), to cut the tape. As shown in Fig. 1, one end of a tape 8 is secured inside a lock 6 and the other, having been passed around the object to be bound, is wrapped round a cable harness 7, passed through the lock 6, a stopping device 10 which prevents return movement of the tape and a similar device 11 pivotally mounted about a pin 13 on the front end of a drawing bar 12. To tension the tape the handlever 4 is rotated in the direction of the arrow about a pin 3, a projecting pin 26 causing a rocker arm 18 to rotate clockwise about a pin 19 until a shoulder 28 of the drawing bar 12 engages a stop 27 on the tool body. The movement of the drawing bar 12 slides the pin 13 to the right and thus the device 11 is also moved in a direction to tension the tape as illustrated in Fig. 2 (not shown). Subsequent release of the handlever 4 allows the tool elements to resume their positions as shown in Fig. 1 under the influence of springs 22, 43 and the tape 8, which is held by the stop 10, slides to the right relative to the device 11. The handlever action is repeated as many times as necessary to increase the tension in the tape. A pin 15 in the drawing bar 12 rests against a flank 16 of a cut out edge 17 in the rocker arm 18 until the force acting on the pin along the flank due to the tape tension exceeds that due to the spring 23, when the pin slides out of the recess and on to the edge 20 of the arm, Fig. 3 (not shown), the pin being rotatable to minimize friction. The tension in the spring 23 is previously set by an adjusting screw 24. The handle 4 is now disengaged from the device 11 and may move further to the right than possible before due to the engagement of the drawing bar 12 with the stop 27. A pin 31 on the hand lever 4 now engages the end 32 of an arm (34), as illustrated in Fig. 3 (not shown), which it rotates about a pin 33 secured to the tool body until a projection (36) on the arm pushes a pin 9 into the lock 6 to connect the tape ends, the arm engages a projection 41 on a lever 40 to free the stopping device 10 from the tape to relieve it of tension, and finally the blade (35) cuts the tape.

Abstract: 1305674 Controlling fuel supply electrically UNITED STIRLING (SWEDEN) AB & CO KB 21 May 1971 16259/71 Heading G1N [Also in Divisions F1 F4 G3] In an external combustion hot gas engine, e.g. a Stirling engine, fuel is fed under constant pressure to an atomizer in a combustion chamber 4 via a valve PV which is closed and opened alternately during time intervals of a constant frequency and to a constant degree of opening, the ratio of open to closed periods in each time interval t (i.e. mark/space ratio of valve control pulses) being varied in order to regulate the mean rate of fuel supply to the atomizer. Signals from a combustion chamber temperature sensor 5 are amplified at 6 and compared with a desired temperature value in a unit 7 and the resultant difference value signal is fed to a pulse with modulator PG together with a signal from a frequency generator FG. The output of PG is a pulse train the widths #t of the successive pulses of which vary with the difference between the actual and desired temperature. The pulse train is fed to a solenoid of valve PV, the leading edges of the pulses occurring at a constant frequency and causing the opening of valve PV while the trailing edge of each pulse causes the valve to close at a time #t after each opening thereof. #t may be varied between 0 and 100% of the time interval t. Combustion air is fed to chamber 4 via a conduit 8, being driven by an impeller I. The impeller delivery is governed by signals from a diode function generator DFG in dependence upon signals from the temperature comparator unit 7.

Abstract: 1314230 Internal shoe drum brakes; wear adjustment AUTOMOTIVE PRODUCTS CO Ltd 27 Oct 1971 [5 Nov 1970] 52721/70 Heading F2E An internal shoe drum brake has brake shoes 12, 13 operable alternatively by a double-acting hydraulic cylinder 19 and by a mechanical linkage including a lever 23 extending with a lost motion clearance through a slot 24 in the web 16 of shoe 13; the brake incorporates an automatic adjusting device including a strut 21 extending between the two shoes 12, 13 and a wedge member 29 interposed between the strut 21 and an abutment member 25 on the brake shoe 12 and slidable under the action of a tension spring 32 to push the strut 21 toward the shoe 13 to compensate for brake wear if the aforesaid clearance is taken up without full brake application. As shown, the abutment member 25 is pivotally mounted on the web 16 of shoe 12, although it may be fixed thereto, and the wedge member 29 projects between edge surface 26 of the abutment member 25 and a notch 31 in the strut 21: the wedge member 29 is guided for sliding by a stepped tubular member 39 engaged in a slot 41 in the wedge member 29 and is retained against the shoe 12 by a spring loaded washer 43 carried by a steady pin 44. The lever 23 is urged clockwise by a tension spring 34 against an abutment 35 fixed to the strut 21 and a torsion spring 36 acting between the strut 21 and the shoe 13 tends to urge the outer side of the slot 24 against the outer side of that part of the lever 23 which passes through the slot 24. The lever 23 has a cranked arm 46 connected to a mechanical brake applying linkage which is actuable to pivot the lever 23 relative to the strut 21 to move the strut 21 and the shoe 13 in opposite directions to apply both shoes 12, 13 to the drum 11. During hydraulic actuation by cylinder 19, the strut 21 and lever 23 move initially with the shoe 12, the lever 23 remaining in contact with the abutment 35 and moving towards the inner end of the slot 24. If before full brake application the clearanc between the lever 23 and the inner end of the slot 24 is taken up further relative outward movement of the shoes 12, 13 pulls the strut 21 away from the shoe 12 so that the wedge member 29 is free to move under the action of spring 32 to take up the resulting clearance. Upon brake release the tension spring 36 pulls the brake shoe 13 inwardly to an extent determined by the clearance. The wedge member 29 is shaped as to only allow adjustment to the maximum safe extent when an edge of the member 29 engages abutment member 25; members 25 and 29 are roughened to provide good grip.
