Patent GB-794112-A (GB)
Abstract: 794,112. Selective printing. BELL PUNCH CO., Ltd. Jan. 20, 1956 [Feb. 7, 1955], No- 3611/55. Class 100(4) A printing mechanism comprises a series of printing members 132 carried on an operating mechanism, e.g. a channelled type bar 130, and is so arranged that as the operating mechanism is moved in one direction a printing member is selected from the series of printing members 132, and as the operating mechanism is moved in the reverse or a further longitudinal direction, the selected printing member is moved relatively to the operating mechanism to effect a printing impression. The mechanism is described in relation to a calculating and/or accounting machine described in Specification 699,914 [Group XIX] wherein the operation of a key 2 sets numeral wheels 1. The setting action described in that Specification also effects operation of the printing mechanism and a bell crank 6 is modified to integrally incorporate a ratchet quadrant 100. This ratchet 100 is, bv the depression of a key 2, rocked clockwise an amount depending on which key is operated and upon the amount of forward movement of a selector bar 22 and a pawl 101 engages in a corresponding tooth of the ratchet. After positioning of the bar 22 a coupling bar 9 continues its forward movement by momentum and a lug 21 parts bell crank 14 and a tail piece thereof pushes down a pawl 49 and an actuator pawl 54 engages with a continuously rotating drive roll 56 to shift the bell-crank lever 6 in counterclockwise direction Since a pawl 101 is in engagement with a selected one of the teeth on the ratchet 100 an arm 102 is lifted and crank 105 rocked, which by link 129, raises the type bar 130 so that the selected type is hooked behind a latch pawl 138 and in alignment with a platen 156. When the ratchet has reached the limit of its return travel a pin 127 thereon pulls a long link 125 which pivots a releasing member 122. This disconnects a hook 123 from a flange 113 of a toothed drive pawl 112 which engages a drive roller 121 and effects a return or clockwise movement to the crank 105. Because the selected type member 132 is latched by the pawl 138, the downward movement of the type bar 130 effects a rolling, steadily increasing impression to be made on a paper web 154 through an ink-ribbon 155. Abutment fingers 133 on the type 132 ensure that the type next above is clear of the printing position. Continued downward travel of the type bar 130 eventually causes the pawl 138 to clear the selected type member 132 and when all the type 132 have moved past, a spring 135 returns all the type to rest position. Only one key 2 may be depressed at a time, because, if a key bar 33 is already displaced a second key will engage a portion 34 and prevent downward movement.

Title: Apparatus for discrimination against spurious elastic wave (e.g. ultrasonic) pulses in the detection of disturbed liquid interfaces or surfaces
IPC: G01F23/296
Filed: 1981-06-15
Abstract: Where detection of reflected ultrasonic pulses is employed for indicating the level of a liquid surface 13a or interface which is subject to mechanical disturbance, erroneous indications can arise from signals reflected by entrained bubbles of gas 15a or drops of one liquid within another. In addition, the desired signal from a disturbed surface or interface may not always be recognised because the instantaneous amplitude of the signal can vary over a wide dynamic range. Such problems are eliminated or reduced by employing two or more transducers 14a, 16a and coincidence signal detection techniques (Fig. 4, not shown). <IMAGE>
