Title: Improvements in or relating to electronic storage tubes and circuit arrangements embodying such tubes
Inventor: WEBLEY REGINALD SIDNEY
IPC: H01J31/58
Filed: 1951-03-17
Abstract: 701,704. Electron beam apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 17, 1952 [March 17, 1951], No. 6456/51. Class 39(1) An electronic storage tube having a charge storage electrode is arranged so that to perform a writing operation the storage electrode is charged by means of secondary electrons and to perform a reading operation photo-electrons are employed. The storage tube 1 may comprise a mesh electrode 3 coated on one side with insulating elements 4 on which charges are stored, a mesh electrode 5, a photo-cathode 2 and an electron gun 6. The cathode 2 may be at zero potential, the storage electrode 3 at 0.5 volts. the mesh electrode 5 at 3 volts, the wall coating 7 at -10 volts and the gun 6 at -1500 volts. The signals to be stored, for example radar signals, are used to modulate the electron gun 6, the beam from which scans the cathode 2 and causes secondary emission which charges the insulating elements 4 negatively. In reading, a flying light spot on a cathode ray tube 9 is focused on the photo-cathode 2 and causes photo-emission, and the number of photo-electrons which pass through the mesh 3 to the signal electrode 5 is determined by the charges laid down in the elements 4. To remove the charge image on the mesh 3 the cathode 2 may be pulsed negatively during a frame fly-back period and flooded with light so that photo-electrons are released with sufficient energy to drive the elements 4 to a positive potential.

Title: Device for protecting repeaters against disturbances in the carrier wave system
Inventor: WAGENMAKERS JOHANNES
IPC: H04M7/10
Filed: 1970-02-11
Abstract: 1284648 Line transmission systems NETHERLANDS POSTAL & TELECOMMUNICATION SERVICE DIRECTOR GENERAL OF 11 Feb 1970 [11 Feb 1969] 6656/70 Heading H4R The repeater relays, each of which is operated by a respective supervisory signal of a channel of a carrier wave circuit, are kept in their existing state in the case of a simultaneous interruption of all the supervisory signals. As described the supervisory signal receivers actuate contacts S1, S2, ... S(n+1) Fig. 1, to operate corresponding relays over a first coil 1, 2, which relays can self hold by energization of the second coil 3, 4 via the respective contacts m1, m2 &c., and the control circuit 10, which is sensitive to the state of all the supervisory signal receivers. The control circuit operates to maintain the relays in their existing condition if all the supervisory signals disappear simultaneously, or the last signal disappears within 10mS of the remainder, while if the last signal disappears after this time the signal is interpreted as a valid signal. The control system 10 is shown in Fig. 2 and comprises an "and" gate 1 which gives an output only when none of the switches S1 to S(n+1) are operated, and a threshold circuit 7 which provides an output when only one or none of the switches S1 to S(w+1) are operated. The output from the threshold circuit 7 operates a monostable trigger 8 which provides an output on line e for 10mS to enable "and" gate 4. If the last channel clears within 10mS of the last but one channel "and" gate 4 will be operated, providing a signal to set bi-stable 5, the output from which is applied through "or" gate 9 to operate relay N which enables the holding of relays M1 to M(n+1) in their existing condition. If the last channel clears more than 10mS after the last but one channel the relay N is operated via "and" gate 6 after a delay of 300mS, due to delay circuit 2, enabling the signal interruption on the last channel to be treated as a desired signal by the repeater.

Title: Machine plant in a housing
IPC: F16M3/00
Filed: 1977-02-18
Abstract: The housing has the external dimensions of a standardised freight container and has a base frame (12) which is secured on the floor of the housing and on which is mounted a machine unit. The load-bearing part of the floor of the housing consists of a frame construction (13) which has two continuous outer longitudinal members (14), cross members (15, 16, 17, 18) and two central longitudinal members (19). The central longitudinal members (19) start from one narrow side of the floor of the housing and extend as far as the third cross member (17). The centre distance of the central longitudinal members (19) corresponds approximately to the track width of transport rollers (24) mounted on the base frame (12). Guide rails (25) arranged on the central longitudinal members (19) serve for the lateral guidance of the transport rollers (24) when the machine unit is rolled into or out of the housing on the base frame (12). To anchor the base frame (12) on the frame construction (13), foundations (20) in the form of two rails are arranged parallel to the central longitudinal members (19), between the second and third cross member (16, 17). While having a large load-bearing capacity, this frame construction (13) permits a small overall height so that when the overall height of the housing is limited, there remains a large clearance within the housing for the machine unit. <IMAGE>
