IPC: H01J17/04
Filed: 1927-03-03
Abstract: 267,136. Dallenbach, W. March 4, 1926, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-In leading in current to, and securing in place, electrodes in metal-walled, low-pressure discharge devices, particularly those filled with gas or metallic vapour, discharges near insulating material tending to result in short-circuits and leaks are prevented by providing conducting parts covering the surfaces facing the vacuum of all insulators over which a dangerous voltage drop occurs, the parts being so arranged that, disregarding the conductivity of the gas and insulators, the voltage drop along these surfaces is concentrated on one or more narrow zones, the width of which in the direction of the electric field is of the order of magnitude of, or small compared with, the mean free electron path in the gas and which zones are spaced by a distance several times their width from each other and from the points where the insulators adjoin or contact with conducting parts. The potential drop along the surface of the insulator J. Fig. 2, between an electrode 3 and the metal wall G mav be concentrated into two annular zones by a metal ring R and extensions F<1>, F on the electrode E and wall G, the gaps being narrow and distant from the points X' - - X<4> of contact of the insulator J with metal parts. In a modification, the ring R is omitted and the parts F, F' shaped to form a single gap at the centre of the insulator J. Insulators wholly in the vacuum and holding electrodes, screens or other protective devices are similarly protected. The Specification as open to inspection under Sect. 91 (3) (a), comprises also a construction with five rings about the insulator J forming four narrow gaps the rings and the electrode E being surrounded by a metal screen narrowly spaced therefrom and in contact with the wall G; and also a construction with a glass vessel G<1>, Fig. 3 (Cancelled), protected by concentrating the potential drop by an extension K on an electrode E narrowly spaced from a screen H, the screen being at the potential of the surrounding gas or of another electrode or of a metal part of the envelope. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the control of feed of machine tools
IPC: G05B19/04
Filed: 1957-02-26
Abstract: 822,955. Machine-tool details. WERNER H. H., and RUDIGER, F., [trading as WOHLENBERG K. G., H.]. Feb. 26, 1957 [March 3, 1956], No. 6381/57. Class 83(3). [Also in Group XL(b)] Means for controlling the feed of a member 9 in a machine-tool comprise an electronic counter set to the number of pulses to be applied to the feeding means 1, the counter having sections 11, 12 counting respectively non-decodic fractions and wholenumbers, the former counter 11 emitting a pulse when it has counted a whole-number to step forward the latter. A motor 1 coupled with a spring-brake 2 rotates a feed-screw 4 and a perforated disc 5 co-operating with photo-electric means 6, 7 for producing the pulses. The pulses are fed through a pulse-shaper 10 to the first decade of the counter 11. When the counter section 11 reaches 999, the following pulse resets it to 000 and a pulse is supplied to the fourth decade 4D of the counter-section 12. The pulse is also passed to a pre-selector 13 which sets the counter-section 11 to 360. The countersection 11, 12, are pre-set by a punched-tape or by a keyboard 16, the values being transferred by a push-button 17 or a cam-operated switch 18. The machine is thus similar to that described in Specification 793,473 with the addition of the pre-selector 13 to measure feedmovements in <SP>1</SP>/ 64 ths inch. A pulse-generator 15 supplies a set number of pulses to compensate for over-running of the motor 1, which is slowed-down prior to the end of a feed by a pulse emitted by the counter-section 12. Reference has been directed by the Comptroller to Specification 793,473.

Title: Improvements in or relating to electro-magnetic waveguides
Inventor: SPENCER ROLF EDMUND
IPC: H01P1/02
Filed: 1952-03-20
Abstract: 732,443. Waveguides. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 11, 1953 [March 20, 1952], No. 7153/52. Class 40 (8). The curvature of a bend in a waveguide increases gradually from each end to a maximum in the middle. The dimensions of the bend are chosen by first determining a minimum radius # 0  to produce a reflection coefficient within acceptable limits. Thereafter the curvature at various points is determined by the relationship where S, the total length of the bend, is equal to 1.5## 0 . In such a bend the square of the curvature varies linearly with the distance s from the mid-point of the bend. Bends in which the square of the curvature varies with the square or root of the distance may also be constructed. In order to reduce the impedance change at the bend, it is arranged that the width a of the guide decreases linearly from each end of the bend to its mid point such that the minimum width a<SP>1</SP> is less than the width of the straight guide by where (#gm/#m)<SP>2</SP> = ¢(#g/#) 1 <SP>2</SP> + ¢(#g/#) 2 <SP>2</SP>. #g, A are the wavelengths in the straight guide and in free space and suffixes 1 and 2 denote the frequency limits for the guide.
