Abstract: 1,227,753. Endless conveyers; feeding sheets. BINKS-BULLOWS Ltd. 5 July, 1968 [13 July, 1967], No. 32298/67. Headings B8A and B8R. [Also in Division H1] The presence of an article 15 on a conveyer 26 prevents a jet of fluid (for example, compressed air) from a nozzle 14 from impinging on a pivoted vane 10, either directly or via a tube 13 as shown. This allows balance weight 16 to rotate an arm 11 which urges a resilient arm 22 to the position shown where it is engaged by a bar 19 of one of a plurality of actuator elements 18 carried on a rotating table 17, only three elements 18 being shown. Each element 18 is pivoted on a spindle 20 for limited movement between stops 21 and carries a roller 23 which, after the bar 19 has been engaged by arm 22, serves to actuate a control device 24 after sufficient rotation of table 17. Device 24 may, for example, be a switch or valve. Table 17 is driven in synchronism with conveyer 26 such that the delay in operation of, for example, a paint sprayer by device 24 corresponds to the travel of article 15 from the nozzle 14 to the paint sprayer position. Means, such as projection 25, restores bar 19 after it has actuated device 24, the position of which may be adjustable. Where an empty work carrier might interrupt a single jet two nozzles 14 may be provided, both jets having to be interrupted to cause operation of the vane 10.

Abstract: 1,228,491. Transistor logic circuits. MULLARD Ltd. 19 April, 1968, No. 18676/68. Heading H3T. A logic circuit has two or more input emitter follower transistors T 3 , T 4 , T 5  connected to the base of a first transistor T 1  of a current switching pair and the common collector potential supplied as a reference voltage for the base of the second transistor T 2  of the switch. In Fig. 1, if any of the inputs to transistors has a logical value 0 then the current shown as I C  is the result of both transistors T 1  and T 2  conducting, whereas only T 2  conducts if an input has a logic value 1. The output is taken from the collector of transistor T 2 . Diode V D  enables a reduction in the value of resistor R 1  thus increasing the gain and hence the value of negative feed-back. In a modification (Figs 2 and 3, not shown), a further transistor (T 6 ) is emitter coupled to T 3 -T 5 , its base potential being derived from a voltage divider across the supply, or from a voltage divider connected between the collectors of T 1  and T 2 .

Abstract: 1,266,260. Acoustic holography. COMPAGNIE GENERALE D'ELECTRICITE. 15 June, 1970 [16 June, 1969], No. 28970/70. Heading H4D. In a system for forming an acoustic hologram of an object by combining echo pulse signals from the object with a reference signal, the disturbing effects which variations in acoustic velocity (due to heterogeneities in the acoustic wave propogation medium) have on the hologram are reduced by deriving the reference signal from echo signals received just before the object echo signals. In the ship-borne embodiment shown a programming unit 2 defines sequences each comprising (Fig. 2) an acoustic emission period 20 (#100 Ás), a reception period 22 (<1ms) occurring a selected time (10-120 ms) after period 20 and thus defining the range of an object 10 whose echoes are to be received, a recording period 26 and a recorder read-out period 28. Echoes of an acoustic pulse of 250 kHz waves emitted by transducer 4 in period 20 are received at a rectangular array of, e.g. 10,000 transducers 100, 200, ..., each followed by its own processing channel. In such a channel, gate 104 is opened in a "pre-reception" period 24 by unit 2 and passes back-scattered echo signals from water inhomogeneities near object 10 to trigger an oscillator 106 (e.g. a high Q resonant circuit) which thus provides a phase reference signal. Gate 102 is then opened in period 22 to pass the object 10 echo to synchronous detector 108 which also receives the phase reference signal. The output of detector 108 represents phase and amplitude data of the object echo and is temporarily stored in memory 110. Similar memories are provided for the other transducers 200 &c. and in period 26 the memory contents are transferred successively to hologram recorder 8 which may comprise an electric scanning tube in which the transparency of a plate is made a function of the memory 110 signal at a point on the plate corresponding to the position of the associated transducer 100 &c. in the rectangular array. The plate is illuminated by coherent light to reconstruct an image of object 10. In an alternative embodiment, a single oscillator 106 preceded by a single gate 104 may be used for a group of several transducers: the reference signal for combination with the outputs of these transducers then being the mean of the several reference signals for this group in the embodiment shown.
