Title: Improvements in velocity-modulated electronic valves
IPC: H01J25/30
Filed: 1946-05-17
Abstract: 625,031. Velocity-modulated tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 17, 1946, No. 15037. Convention date, May 16, 1941. [Class 39 (i)] In a velocity-modulation tube of the concentric electrode type, with cathode 15, Fig. 1, negative grid 16 and positive grid 17 between which density modulation takes place, an outer grid 18 of the same potential as grid 17 and forming with it a field-free space, and an anode 19, the field-free space is divided into compartments by a series of radial partitions CD, EF, &c., Fig. 3. The grids 17 and 18 may be formed by the inner and outer edges of the partitions themselves, and these may also be wedge-shaped, so that the compartments are of equal width, Fig. 5 (not shown). The inner openings to the compartments may be partially closed by transverse plates, and the outer openings by a lattice mesh, Fig. 4 (not shown). In a modified arrangement, the inner edges of the partitions engage in V-shaped members 22, Fig. 6, which have a different potential from the partitions, the respective dimensions and potentials being such that the grouping space is still substantially field-free. The invention may also apply to arrangements with central anode and exterior cathode. The Specification as open to inspection under Sect. 91 also describes the basic arrangement of two grids and an anode only, without partitions and third grid. In Fig. 5 (Cancelled), the grids are connected directly via two concentric conducting annuli 2 and 3 in an insulating base-plate 1 to the inner and outer conductors 9 and 10 of a coaxial line, which may alternatively extend inside the envelope, serving to support the grids directly. In a further modification, Fig. 9 (Cancelled), the coaxial lines forming the oscillatory circuit are contained wholly within the envelope, an antenna 14 serving to outcouple the energy. This subject-matter does not appear in the Specification as accepted.

Filed: 1926-06-17
Abstract: 263,403. Soc. Anon. des Anciens Etablissements, A. Savy, Jeanjean, et Cie, À Baker Perkins, Ltd., and Lebert, L. March 12, 1926, [Convention date]. Waffle baking-apparatus. - In waffle-making apparatus, the irons are so made that when the space between the plates is practically closed, and at the moment of closing, the vapours escape through narrow conduits having a sudden change of direction. As shown in Fig. 3, metal edging strips a are secured to the irons c, the strips a having recesses b through which the vapour from the cooking space e is directed substantially at right angles to the plane of the plates. Owing to the sudden change of direction of the vapours, the traction on the batter is reduced and the waste which passes into the recesses b is sheared off when the irons are completely closed, thereby eliminating the usual scraping off of the waste batter.

Title: Traffic supervisory system
IPC: G08G1/01
Filed: 1958-05-13
Abstract: 895,165. Signalling passage of vehicles. EASTERN INDUSTRIES Inc. May 13, 1958 [May 13, 1957], No. 15315/58. Drawings to Specification. Class 118. [Also in Group XL (c)]  Each of a plurality of sampling stations spaced along a road produces electrical signals indicative of vehicular speed and traffic volume, the speed and volume signals being combined to form a composite signal which is transmitted to a remote central monitoring station where it is resolved into the separate speed and volume signals; these signals are applied to devices which produce therefrom voltages proportional respectively to vehicular speed and traffic volume, these voltages being employed to give visual indications of speed and volume. As described, Doppler radar equipment is used for measuring vehicular speed and traffic volume, and the two Doppler signals (of different frequency ranges) are combined and sent to the central monitoring station where they are separated by filters. Pulses indicating the presence of vehicles are converted to a direct current signal whose amplitude varies proportionately to the number of pulses per unit time, i.e. to the volume of traffic. There may be individual indicator circuits responsive to different ranges of direct current signal (and hence of traffic volume), and alarms for high and low vehicular speeds and particular volumes of traffic,

Filed: 1970-04-01
Abstract: 1,247,635. Road signals for controlling traffic. GULF & WESTERN INDUSTRIES Inc. 1 April, 1970 [1 April, 1969], No. 15380/70. Heading G4Q. Traffic control apparatus for controlling traffic in at least two phases, at least one phase having traffic detectors for actuating the controller and thereby extending the GO period for that phase, has its timing determined by weighted binary counters driven by equi-timespaced trigger pulses. In a first embodiment, Fig. 1, a main street phase #A and cross street phase #B are controlled by a traffic signal S operated by a controller LC-1 influenced by traffic detectors DB in the cross street. The means in the controller LC-1 for extending the time duration of the GO signal in phase #B comprises a plural-stage binary signal store weighted with a binary content the decimal number of which represents the time duration of a GO extension interval. This store provides an output signal to terminate the GO extension interval when the decimal number of trigger pulses received from the trigger pulse source is equal to the decimal number of the binary content of the store. The weight of the binary content of the store is variable, up to a pre-set maximum, by signals received from the detectors DB whereby the time duration of the GO signal may be increased. The complete apparatus is described with reference to Figs. 5, 5A (not shown) and includes a time storage memory matrix. The individual bits of the matrix are formed by ceramic memory devices as described in Specification 1,177,940, each bit comprising a memory plate of ferroelectric material, e.g. barium titanate, mechanically coupled to a drive plate of ferroelectric material having piezoelectric characteristics, e.g. lead titanate zirconate (Fig. 2, not shown). A "1" or "0" is stored in the memory plate in dependence upon the direction of an electric field applied between opposing faces of the plate. The nature of the signal stored in the memory plate is read out non-destructively by applying a read-out interrogation voltage pulse to the drive plate. In another embodiment described with reference to -Figs. 8, 9, 9A (not shown), road traffic detectors are also provided in the main street #A.
