Abstract: 1278589 Control of AC motors; AC generators with DC excitation; protective systems BRITISH OXYGEN CO Ltd 18 Sept 1969 [18 Sept 1968] 44301/68 Headings H2A H2J and H2K Closure of starter switch S energizes relay RY so that the field winding F of alternator B is supplied from battery E through rectifier Z3. The output of the alternator is applied to motor M, excitation of the field winding F being maintained by current transformer T2 associated with rectifiers Z1, Z2. The alternator is driven by the road engine of a tanker, the motor driving a pump forliquified gases. Trip switches TR1-TR4, each comprising a thyristor TH, respond to fault conditions to de-energize the relay RY, short-circuit the secondary winding of the transformer T2, and so de-excite the alternator. The switches TR1, TR2 are connected to thermistors Dl, D2, and protect the windings of the alternator and motor respectively against over-heating. The switch TR3 is connected to fault-detection transformers T1, which respond to excessive rate-of-rise of current, when the current exceeds a specified level, when the interphase currents or voltages become excessively unbalanced, or when there is an earth fault current. The switch TR4 is connected to tachometer generator G and protects the pump against over-speeding. A switch P is in series with the relay RY and remains closed provided that the pressure at the pump outlet is above a specified value.

A reversible conveyer comprises two pairs of endless chains 1, 2 arranged to extend over an elevator section in two parallel planes and to run in a common horizontal plane before returning to the foot of the elevator section. Between the chains of each of the pairs 1, 2 there are connected spaced cross-bars 9, 10 so arranged that a front cross-bar 9 and a rear cross-bar 10 are in common horizontal planes in the elevator section. The sleeves of the cross-bars may rotate during the horizontal run, the chains 1 being supported by bars 16. The chains 1, 2 are driven at the same speed by a drum with radial fins 15 forming grooves of sufficient width to receive the cross-bars 9, 10. The links of chains 1, 2 are half a link out of phase and certain of the links of chains 2 are C-shaped to receive the bars 9 in the horizontal section since the chains 2 are inwards of the chains 1. Articles 21 are fed to or received from the conveyer by endless conveyer belts 22, 17. Fig. 6 (not shown) illustrates an arrangement of two conveyers as described above arranged so that an article may be raised, moved horizontally and then lowered.

Fig. 8 (not shown) illustrates a modification of Fig. 1 wherein part of the conveyer itself forms a loading or discharging conveyer. Laterally projecting discharge bars 13, Fig. 2 (not shown), connected to the front pair of chains 1 project upwards on the horizontal run and so assist in discharging articles 21 over the head drum 5.

Title: Rotary photometric analyser having a data processor
IPC: G01N21/07
Filed: 1974-10-18
Abstract: 1455800 Rotary photometric analyzer UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 18 Oct 1974 [31 Oct 1973] 45148/74 Heading G1A A rotary photometric analyzer has a plurality of cuvets in a rotor, and sample absorption is measured with a photo-multiplier; the rotor gives a timing pulse once per revolution and also gives a pulse for each cuvet. These pulses are used to control the storage of the sequence of absorption measurements made during one revolution of the rotor, and also to control their print-out during subsequent revolutions. Figs. 1A, 1B show the circuitry, in which the output of photo-multiplier 15 is converted to an absorbance value at 16 and digitized at 17 for storage at 37. The rotor pulse delivered once per revolution is shaped at 27, while the pulse given every time a cuvet passes the photo-multiplier is shown as a 'digitize pulse' and is shaped at 36. To commence measurements the print switch 19 is pressed; when the next rotor pulse occurs this changes the outputs of flip-flop 23, and hence enables gate 32 via gate 31. This gate 32 passes the digitize pulses to the A/D converter, so that the photo-multiplier signal is digitized every time a cuvet is viewed, and the signal passes to memory 37. Each successive digitize pulse advances counters 33, 34 and hence ensures via lines 41 that the digitized signals are stored in the correct addresses of the memory. When the rotor has completed a revolution another rotor pulse occurs which changes flip-flop 24, and hence disables gate 32 and resets the counters via gates 31, 46. Nothing then happens until the next rotor pulse, which activates a divider 40 to give a 2HZ signal which controls the printer 20 and also advances the counters. The latter cause the memory to read-out to the printer via inverter 42 and converter 43. The counters give a final pulse to reset the whole system. The cuvet rotor has a reference cuvet for which the photo-multiplier output is automatically set to 10 volts (not shown), and all other signals should be below this, as in Specification No. 1390707. A comparator 18 checks whether any signal above this level occurs, and if so it activates a fault signal at the printer so that the fault is indicated in the print-out.

The stock may be cold-rolled, or may be hot-rolled by passing it through an induction heating oven 16. Rolls 13 rotate about their own axes due to contact with the stock, and equal running speed of the rolls is ensured by a synchronizer 17.

Abstract: 1,205,640. Filling sausages. TEE-PAK Inc. 6 Oct., 1967 [6 Oct., 1966], No. 45662/67. Heading A2B. A machine for making sausages of a substantially uniform diameter, comprises means movable towards and away from a stuffing horn, for applying a variable force in opposition to the direction of sausage casing flow for pressing the casing against the horn to regulate the flow of casing from the stuffing horn, which means are controlled by means sensing the diameter of the sausages so that when the sausage diameter tends to increase the force is reduced to allow a faster rate of casing flow to maintain the sausage diameter substantially uniform. As shown the apparatus comprises a stuffing horn 5 through which sausage meat is forced under pressure into casing 27, elastic ring 26 (e.g. of rubber or plastics) for applying the variable force, internally ribbed sleeve 2 for sensing the sausage diameter and clipper 25. Ring 26, sleeve 22 and clipper 25 are mounted on carriage 13 which is slidably movable along rods 10 towards and away from the stuffing horn 5 by threaded adjustment means 43-46. In use the carriage 13 is moved adjacent the stuffing horn 5 and the compressive force of spring 40 mounted on the carriage 13 and acting on the levers supporting the sleeve 22 and ring 26, is adjusted to apply the desired force to the casing 27. If the sausages become of larger diameter than desired they engage sleeve 22 and pull it and hence ring 26 away from the horn 5. The force being applied to the casing 27 is decreased and the flow of casing is speeded up to reduce the diameter size of the sausages. When the diameter has been reduced the ring 26 and sleeve 22 are returned to their original position by the action of spring 40.
