Title: Strap Tightening and Cutting Tool
IPC: B65B13/02
Filed: 1967-08-02
Abstract: 1,193,449. Strap tensioning devices. THOMAS & BETTS CORP. 2 Aug., 1967, No. 35545/67. Heading F2G. A manually-operable strap tightening and cutting tool comprises a body 12 into which a strap 24 can be drawn, a rocker arm 15 movably connected to the body, a cutter portion 20 adapted to engage the strap upon movement of the arm 15, a spring 18 arranged to oppose movement of the arm, and strap gripping means movable with respect to the tool body; a handle 25 is movably connected to the body and there are rigid plate means, i.e. a cam plate 21, operatively connecting the handle to the arm 15, and a tension plate 30 connecting the strap gripping means to the handle so that an operative tension stroke of the handle causes a strap held by the strap gripping means to be drawn into the tool body by a corresponding amount. The connections between the handle, cam plate and tension plate is such that a force applied to the handle to move a strap beyond the furthest point that it can be drawn into the tool by one or more operative tension strokes of the handle causes the cam plate to move the arm 15 against the spring 18 so as to engage the cutter 20 with the strap thereby to cut the strap. In operation, a pawl 35, pivoted on the tension plate 30 and biased against a flange 39 on the plate, grips the strap 24 between itself and the flange when the handle 25 is moved towards the grip 13 and on release the handle the plate and pawl return to the initial positions as seen in the Figure whereby the pawl, on striking the nosing 40, disengages from the strap; by repeated movement of the handle the strap is drawn progressively through the tool and tensioned around an object A. When further movement of the strap into the tool offers sufficient resistance to prevent movement of the handle about a pin 26, the handle pivots about a pin 31 since the plate 30 is frictionally lockedto the strap 24 by the pawl 35 and at this stage the cam plate 21 is rotated so that the flanged ends 22, 16 of the plate 21 and rocker arm 15 respectively to abut and cause the arm to rotate and the cutter 20 to move downwardly to cut the strap.

[Class 100 (iii)] Chases; locking devices.-In a chase having locking-up means in the form of sliding wedge- 'bars 3, Fig. 1, which engage co-operating inclined surfaces, on side and foot sticks 2, the wedgebars are operated by toggle-mechanism including finger-levers 10, Fig. 3, which are so arranged that, during at least the final part of the clamp-  ing movement, the operating force is applied in a direction normal. to the face of the chase. Each lever 10 . is pivoted to a sliding rod 7, which operates the wedge-bar 3 through a spring 4, and the lever is connected by a link 12 to the chase frame 1, so as to form a toggle. When the lever is depressed to effect the clamping, the pivot 11 connecting it to the link 12 passes the dead-centre position, so that the clamping is maintained by the spring 4. The lever then lies in a recess in the chase. The outer ends of the levers are cranked, so that their operating parts 13 lie side by side. A single lever may operate both the wedge-bars. The springs 4 may be replaced by series of spring plungers 25, Fig. 4, mounted in a bar 23, which is placed between the side or footstick 2 and the type matter, so that the plungers bear against the type. The various columns are thus individually locked by the plungers., The bars 23 may be reversed, so that the plungers bear against the side or foot stick.

Title: Pressure drop monitoring system
IPC: G01M3/28
Filed: 1977-08-25
Abstract: 1529556 Testing pipe-lines for leaks LEDEEN FLOW CONTROL SYSTEMS 25 Aug 1977 [30 Aug 1976] 35754/77 Heading G1S [Also in Division C3]  A pipe-line pressure drop monitoring system comprises means 28 for producing an actuating signal in response to each decrease in pressure of  a given increment, means 46 activated by this signal to produce an energizing signal for a predetermined period, and means 50 conditioned by the energizing signal to produce an output signal if energized for a time longer than the said predetermined period. The output signal may act to close a valve 76 in the pipe-line. The pressure in the pipe-line upstream of the valve 76 is supplied to both ends 30, 32 of valve 28, which is biased by spring 33 to close port 27. If the pipe-line pressure falls by a given increment the pressure at end 30 will fall (the pressure at end 32 being held by check-valve 34) and a pressure signal will be passed by the valve 28; this acts via conduit 41 to open the check-valve 34 and allow the valve 28 to close, to terminate the pressure signal, and also acts to open valve 46 and allow a pressure signal to pass from conduit 58 via conduit 60 to the valve 50, which opens only after a time determined by timer 53. When the signal from valve 28 ceases timer 47 holds the valve 46 open for a predetermined period which is shorter than the time set by timer 53, so that the valve 50 does not open; however if the pipe-line pressure is falling at such a rate that a further signal is passed by the valve 28 before the end of the period set by the timer 47, the signal from the valve 46 to the valve 50 will be continuous, and the valve 50 will open, actuating valve 68 to close the valve 76. Two parallel systems with different set times may be provided, Fig. 4 (not shown). The actuating fluid is normally gas from the pipe-line, but if the pipeline is conveying liquid a separate gas source (118) may be provided, Fig. 5 (not shown).

Title: Improvements in electrical apparatus for transferring data
IPC: G06F3/08
Filed: 1957-11-18
Abstract: 856,303. Digital data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1957 [Nov. 17, 1956], No. 35907/57. Class 106 (1). A device for transferring data from a record card to a main store the rows of the card being read successively is characterized in that the data from each row is entered first into a buffer store from where it is serialized, recoded and entered into the main store before the next row of the card is read. The card is sensed by 80 brushes 1B-80B, Fig. 2, and the data from each row is copied into a row of magnetic cores 1m-80m, from where it is serialized under the control of a chain of 80 triggers b1-b80, recoded by contacts R1-R8 and entered via leads l1-l8 into four rows of 80 cores each which constitutes the main store. At the same time the data that was in the main store is read out and re-recorded also via leads l1-l8. The actual reading and recording occurs as follows: The chain of triggers is advanced one step in a direction from b80 towards b1 for each cycle of a ring of 4 triggers Bz, Bl, Br and Be, which are advanced by a multivibrator G. Read out from the cores occurs when trigger Bl is "on" and read-in to the main store occurs when trigger Be is " on." For example, if trigger b3 is " on " the associated column of the main store and the associated core of the buffer store are together read out by a signal from trigger b3 via a gate 31. However, since each column of the record card contains only one digit represented by one hole, both core 3m and column 3 of the main store will not be storing data. If core 3 is storing a bit then it will be read out to a trigger Bm and when the "on condition in the ring Bz-Be reaches trigger Be signals on leads l1-l8, produced by contacts R1-R8 under the control of trigger Bm will be applied to the main store together with a half-write signal from a gate 31 to cause the entry into column 3 of the main stores of bits representative of the particular row from which the bit in core 3m had been read. If, however, column 3 of the main store contains data then it will be read out into triggers B1-B8 and re-written in its original position when trigger Be goes " on." The device is arranged so that when the first row of the card is read any data that was in the main store is destroyed, and it is stated that means are provided for reading out the complete contents of the main store after the data from one card has been completely entered and before the next card is read. Specification 855,877 is referred to.
