Title: Photoemissive Image Tube Manufacture
IPC: H01J9/46
Filed: 1978-08-26
Abstract: In manufacturing a photoemissive image tube (e.g. proximity-focussed channel multiplier type intensifier, or camera tube) the cathode section and/or anode section are processed in isolation from each other within respective temporary chambers (Figs. 4, 5) including temporary chamber forming members 19, 36. In subsequent manufacture, following storage if desired, one cathode section module and an anode section module are selected, mounted within a vacuum chamber, the temporary chambers, opened such as by tearing (Figs. 6, 8 not shown) using hydraulic ramp to expose the photocathode and anode sections and the two sections are brought together and sealed, such as by pressure sealing tools 52, 53 (Fig. 7, not shown) for a Cu-Cu cold seal. Getter 54 is activated as the temporary seal is destroyed. Figs. 9, 10 (not shown) include a magnetically operated hinged cover (71) for the processed p/c, and the temporary seals may be opened by cutting rather than tearing (Fig. 11, not shown). Further details of the seals are given. <IMAGE>

Title: Gain controlled amplifier with variable frequency response
IPC: H03G9/16
Filed: 1978-12-14
Abstract: A gain-controllable amplifier with the frequency response of which varies with gain and which may be used as a physiological volume control circuit comprises two virtual-earth amplifiers connected in parallel. Each amplifier includes a differential pair gain control circuit (T1, T2 and T3, T4 respectively) which pairs are cross-connected. The feedback impedance (Z) of one virtual- earth amplifier is frequency- dependent, and a variable gain control voltage (UST) is applied between the bases of the transistors of each pair. In order to be able to obtain a large gain variation range with the frequency response varying to a considerable extent over a large part of this range, one differential pair (T3, T4) is shunted by a further transistor (T7) which itself is fed with an independently variable control voltage (Usth). A further controlled differential pair (T8, T9) may be provided to keep the d.c. conditions constant. <IMAGE>

Title: Improvements in or relating to spraying equipment
IPC: G01B17/00
Filed: 1979-06-26
Abstract: Agricultural or horticultural spraying equipment in which spraying is effected by means of a series of spraying nozzles mounted on a spraying boom which extends outwardly of a main body of the equipment. To maintain the boom parallel with the ground two transmitters and receivers are provided at locations spaced in a direction lengthwise of the boom. One transmitter and receiver is mounted on the boom and the other on the boom or on the body of the equipment. Each transmitter and receiver transmits sonic radiation downwardly towards the ground and receives radiation reflected back from the ground or from a crop growing in the ground. The difference between the times taken for radiation to travel to and from each transmitter and receiver represents the amount by which the boom has moved from parallelism with the ground. This difference is determined and used to generate a signal for actuating means which pivot the boom back towards parallelism. <IMAGE>

Title: Hamburger-type sandwiches
IPC: A23P20/25
Filed: 1979-11-14
Abstract: The invention concerns a foodstuffs of the hamburger type comprising a bread roll (14) having a toasted internal cavity (20) into which is fitted a heated sausage (24) of the frankfurter type, the dimensions of which are such that the sausage completely fills the cavity (20) and extends therebeyond. Liquid condiments such as sauce or a soup, can be poured into the interior of the roll before the sausage is added and it will be seen that the sausage effectively prevents the liquid material from running out of the foodstuff. The toasting of the interior of the cavity by heated spike 16 reduces the saturation of the bread interior of the roll by the liquid foodstuff. <IMAGE>

Title: Correcting Non-linearities in Optical Scanners
IPC: G01B11/00
Filed: 1980-05-14
Abstract: Correction of recurring non- linearities in the scan time of an optical image scanner 11 includes a calibration stage in which an accurately located grating 14 having alternating optical properties at known intervals is scanned and the times at which the changes are detected are compared with the stored times representing the times at which detection should occur for the grating to give a time error for each of the times measured. The errors are stored in a store 27 at locations defined by the measured times. In scanning an object each measured scan time at which a change in optical properties is detected addresses the store and retrieves the error for that time, which is added to the measured scan time to give a linearity corrected value. The times are represented by clock pulse counts and the manipulation and storage is digital. <IMAGE>

Title: Needle monitor for knitting machines
IPC: D04B35/18
Filed: 1980-10-16
Abstract: The machine comprises a feeler (37) to detect a bent or broken needle head. The feeler is displaceable against a bias from a stop-motion position clear of the needles to engage the needle heads (13) of the needles as they rotate, to be maintained displaced from said position by successive engagement of the needle heads with the feeler. The feeler, however, is maintained displaced from said position only for as long as the time interval between the engagements with two successive undamaged needle heads is equal to the time interval between the passage of two immediately successive needles, whereby, when a needle head is bent or broken, the feeler has a sufficient time to move under the bias to the machine stop position, thereby to indicate the presence of the impaired needle and to cause the machine to be stopped. <IMAGE>
