Title: Optical analyzer for agricultural products
IPC: G01N33/10
Filed: 1973-08-16
Abstract: 1432634 Photo-electric apparatus NEOTEC CORP 16 Aug 1973 [24 Aug 1972] 38760/73 Heading G1A In photo-electric apparatus particularly adapted for spectrometric measurements, a filter assembly of paddlewheel configuration is used. The apparatus of Fig. 1, suitable for determination of moisture, oil and protein of grain by reflection optical density measurement, comprises a sample tray 16 by which a sample 20 or reference 18 may be located in the light path. As shown a broad-band infrared source 12 illuminates the sample via filter wheel 34, but for other measurements a light source may be used. The filter wheel 34 has opaque vanes 42 mounted at right angles to each filter and this leads to a transmission characteristic shown in Fig. 4 which has dark portions between the contributions by each filter which exhibit a change in wavelength transmitted as the angle of each filter changes with respect to the beam. The rotation of the filter wheel is sensed at 48 to produce a pulsed signal which is counted at 50 and used to control, via decoder 54 the gating of detector output signals from photo-resisters 44 which are amplified at 46, and acted on by logarithmic amplifier 70, to sample-hold circuits 72, 74. The gating sequence is such that detector output levels at two different filter angles ( and thus two different wavelengths) are fed to the respective sample hold circuits, three times per-filter wheel rotation. The differences between each pair of signals are stored in further respective sample hold circuits 82-86, and then passed via calibration stages 88-92 to the computing-display unit 94, which has a common digital display, switchable to a particular computer for a quantity to be measured Fig. 6 (not shown). The computers may be programmed for different types of analysis by insertable cards. The dark periods of the filter wheel are used to record the dark response of the photo-cells in an integrating amplifier in the feedback loop of the main differential amplifier in unit 46. The calibration units are provided with amplifiers having feedback loops containing manually adjustable resistors. When the sample tray is in the position shown, a calibration sample is being analyzed, switch 130 is in a closed position and the feedback loops are connected, so that recalibration may be carried out.  A suitable sample holder for insertion into tray 16, is illustrated, Fig. 2 (not shown). Although three filters providing six wavelengths, for the analysis of three components, are shown, less or more may be provided, together with necessary additional circuitry.

A transfer press comprises a pair of pillars 1 supporting a cross-beam 2 with integral supports 7 for a cam-shaft 10 which drives a series of rams 9, slidable in a guide beam 3, towards dies 28 fixed to the press bed.

Patent GB-1083167-A (GB)
Title: Digital counting circuits
Inventor: CARBRE ROBERT LAWRENCE
IPC: G06F7/58
Filed: 1964-09-24
Abstract: 1,083,167. Transistor pulse circuits. WESTERN ELECTRIC CO. Inc. Sept. 24, 1964 [Sept. 25, 1963 (2)], No. 38920/64. Heading H3T. [Also in Division G4] In a counter made up of a number of units, each comprising a blocking oscillator (as shown), the division ratio of a counter unit, i.e. the number of clock pulses inhibited by the corresponding blocking oscillator after receiving an initial pulse, is temporarily changed by varying the impedance of a " current decay " circuit connected in parallel with the oscillator transformer 254, or by modifying the emitter circuit of the oscillator transistor. In the former case, clock pulses received via an isolation gate 251 trigger transistor 252 which then allows current to be rapidly built up in primary winding 253 of transformer 254. A resistor 255 and diodes 256 and 257 are connected across winding 253 to provide a normal low impedance discharge path for current in that winding. When it is required to change the counter division ratio, an AND gate 261 is enabled and a positive charge deposited on capacitor 262. When transistor 252 next triggers, an auxiliary winding 263 develops a voltage which forward biases diode 264 and transfers charge from capacitor 262 to capacitor 265. When the transistor cuts off, this positive charge reverse-biases diode 256 through diode 266 and resistor 267 so that the decay circuit is now of high impedance and includes diode 257, resistor 267, diode 266, capacitor 265, the negative voltage source and the primary winding of transformer 268. This circuit therefore reduces the current decay time of the oscillator. Two modifications (Figs. 6, 8, not shown), may also be used to either increase or decrease the impedance of the oscillator decay circuit, and thus vary the division ratio of the counter. Alternatively, by modifying the oscillator transistor emitter circuit using diode (114) (Fig. 4, not shown), and capacitor (115), a pulse received from AND gate (121) removes charge built up on capacitor (115) so that when transistor (108) next triggers, an additional current is supplied to transformer (122) whose resultant increased energy takes longer to decay. Normally the diode (114) is reverse biased by the charge on capacitor (115) so that the effective transistor emitter load is merely resistor (111). In a modification (Fig. 5, not shown), the amount of energy supplied to the transformer is reduced.
