Abstract: 1,023,809. Selective signalling. TECHNICAL MEASUREMENT CORPORATION. May 22, 1964 [June 19, 1963], No.21362/64. Heading G4H. The output, Fig. 2, of a spectrometer (e.g. a nuclear magnetic spectrometer) is analysed by converting it 25, Fig. 3 into a corresponding frequency of pulses and by counting 27 the number of pulses that occur in each of 400 adjacent time intervals, and the arrangement is characterized in that the sweep of the spectrometer to produce its output signal is synchronized with the successive sampling of the corresponding frequency signal. Thus the 400 counts correspond to 400 adjacent ordinates of the output signal, Fig. 2. By repeating this cycle a large number of times and then reading out the counts sequentially and displaying them on an oscilloscope 12 a display is obtained of the average of a large number of output signals, Fig. 2, and as a result the signal to noise ratio is improved. As described a control sample is also put into the spectrometer and is so chosen as to produce a single output pulse P 1 , Fig. 2, below the spectrum from the unknown analytical sample. This peak from the control sample is used to start the successive sampling of the frequency significant pulse train, 30, 29, 26, and to transfer the control of the spectrometer sweep from a first pulse generator 33 to the same pulse generator 29 which controls the sampling, thereby effecting the required synchronization.

Abstract: 1,001,897. Reciprocating pumps. BECKMAN INSTRUMENTS Inc. June 4. 1962 [July 13. 1961], No. 21457/62. Heading F1A. In a pump for delivering a mixture of liquids, the proportion of the mixture is variable without varying the total delivery per stroke. The pump comprises first and second pump stages, the first pump stage being of variable stroke and delivering a predetermined volume of a first liquid to the second pump stage, which also communicates with a source of a second liquid, and makes up its intake capacity with said second liquid. The delivery per stroke from the second pump stage is constant. In the embodiment shown, three second pump stages X, Y, Z arranged 120 degrees out of phase, provide a uniform delivery rate, the first pump stage 14 being reciprocated at three times the rate of the second pump stages and delivering to each in turn. The rate of delivery of the first pump stage is equal to the rate of intake of each of the second pump stages. Each pump stage comprises a piston 45 reciprocable in a cylinder 43 by a cam 71, 72, 73 or 74 acting through a spring- loaded cross head 55. A cup 47 is fixed to each piston 45 and contains liquid to lubricate and clean the sliding surfaces. Stroke varying in pump stage 14 is effected by a cam 85 limiting downward movement of piston 45. Cam 85 may be set to provide a constant mixture ratio, or may be continuously rotated at predetermined speeds by selection of gears 91 and 95 to provide varying mixture ratios. Rotary valves 127, 137, 139 and 141 controlling flow to and from the pump stages are actuated in timed relationship to the driving cams. The driving cams of the second pump stages may be shaped to compensate for volumes of first liquid trapped by the inlet valves, thereby maintaining accurate proportioning. In other embodiments, more than two liquids may be mixed by employing more than one first pump stage. Axially acting cams may be used in place of the radially acting cams.

Abstract: 780,856. Coiling wire around a terminal. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. July 20, 1955 [July 23, 1954], No. 21509/54. Class 83 (4). A tool for wrapping the end of a wire conductor around a terminal tag and having a bit arranged on rotation to wrap the wire around the tag has a continuously rotating flexible drive extending through the handle of the tool arranged to be clutched by manual operation of a trigger device to a rotatable shaft to which the wrapping bit is secured. A shaft 15, rotatable in a shell 11 of the tool, has secured at one end a spindle 28 having an axial hole 31 in its outer end to accommodate a terminal tag to be wound and a longitudinal peripheral slot 30 to accommodate the end of the wire to be wrapped around the tag. A tubular barrel 29 secured to the shell 11 surrounds the spindle 28. The other end of the shaft 15 carries a chamfered rubber annulus 20, the inner end of a spiral spring 22 and a helical cam face formed with a stop 24 and engaged by a spring-urged pin 25. A pivoted arm 46 carries, journalled therein, a coupling member 43 secured to a rotating flexible drive cable 39 passing, in a sheath 40, through a handle 10 of the tool. The coupling 43 is chamfered and, when a pivoted trigger 48 is squeezed to lift the arm 46, engages the annulus 20 on the shaft 15. This rotates the shaft 15 to wind the wire around the tag and also causes the spring 22 to tighten on the shaft 15 until its outer end slides in a channel 23, the pin 25 riding freely over the cam. When the trigger is released the drive to the shaft 15 through the members 43 and 20 is disconnected and the spring 22 rotates the shaft 15 in the reverse direction until the stop 24 is engaged by the pin 25, thus to position the shaft. In a modified form of bit 60, Fig. 3, secured to the shaft 15, a flat tag 62 with slotted edges 66 is inserted in an axial cavity 61 in the bit 60 and the connecting wire is laid through a hole 63 in the cavity wall to lie in a longitudinal peripheral groove 64, said groove being closed externally by a sleeve 65 fixed around the bit 60.
