Abstract: 1,105,727. Pneumatic springs. INSTITUT SVERKHTVERDYKH MATERIALOV. 18 April, 1966, No. 16927/66. Heading F2S. [Also in Division B3] In a device, for guarding against overloads and failures in a power press having a reciprocating sliding block and a stamp, not shown, and an understamp plate 4 with guides 19 mounted in the press bed 5, the plate 4 bears against a plunger 2 which works in heavy duty cylinder 1 supplied with compressed gas, e.g. nitrogen. The space 3 below the piston 2 is made gastight by providing the piston 2 with a sealing member 6 clamped with a ring 7 and by filling the lower portion of the cylinder 1 e.g. with thick oil the level of which is always above the base of the piston 2. The upward movement of the piston is limited by a split ring 8, 9 which has a radial flange received in a groove in the wall of the cylinder 1 and which is fixed in position by a ring 10. Oil is delivered to the cylinder 1 through a cook 18, compressed nitrogen being introduced into the cylinder 1 from a container 11 which is connected to the space 3 through a pipe 15, and cocks 17, 16, the cock 17 being opened to atmosphere while oil is being introduced into the cylinder. The gas in the container 11 is compressed by a liquid which is forced from a tank 13 by a pump 12 into the container 11. The latter has a safety valve 14.

Title: Improvements in or relating to electron guns
Inventor: DAIN JOHN
IPC: H01J23/075
Filed: 1951-07-23
Abstract: 710,954. Travelling-wave tubes; magnetron amplifiers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 18, 1952 [July 23, 1951], No. 17382/51. Class 39(1) An electron gun for producing a beam of electrons having substantially linear trajectories guided by crossed electric and magnetic fields such as for use in a travelling wave magnetron amplifier, comprises a stepped cathode C, an anode A parallel to the cathode, a deflector electrode D located in an equipotential surface in the wider region between the anode and the cathode whereby a 1:2 change in the electric field strength before and after the step is obtained and opposite the deflector an emitting surface centred approximately # times the depth of the step from the step. The emitting surface is of a length within the limits, about 2 to 4 times the depth of the step, at which electrons emitted therefrom strike the deflector or anode. The invention is based on the principle that an electron e starting from rest in crossed electric and magnetic fields describes a cycloid, and that if at the peak of the cycloid the electron suddenly enters a region where the electric field is twice the strength of the field in which it describes the cycloid, the electron will continue in a linear trajectory. By the provision of the deflector, the anode behind the deflector may be dispensed with or at least straightened out. The deflector electrode may be planar and located in the median plane M. It may be located closer to the cathode than to the anode both before and after the cathode step. To provide for transverse focusing of the electron, there may be provided a shield with turned up edges surrounding the emitting surface, and the edges of the upper part of the cathode may also be turned up.

Title: Improvements in or relating to camera tubes with photo-conductive image electrodes
IPC: H01J29/45
Filed: 1954-06-14
Abstract: 763,745. Photo-conductive devices. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 14, 1954 [June 13, 1953], No. 17418/54. Class 37. [Also in Group XL (a)] The photo-conductive image electrode in a camera tube consists of a continuous semiconductor layer, opposite surfaces of the layer being formed from zones of the material of opposite conductivity types. Fig. 1 shows a camera tube comprising an electron gun assembly 3, 5, 7 and a semi-conductor image electrode 21 consisting of a P-type zone 25, and an N-type zone 23, adjoining a signal electrode 19 consisting of a thin layer of gold, iridium or platinum. The semi-conductor may consist of lead monoxide. The N- and P-type zones may be produced by first applying to the signal electrode an intermediate layer comprising a trivalent element such as bismuth or antimony, if desired in the form of trioxide or trisulphide, mixed or not mixed with the semi-conductor lead monoxide, then applying the semi-conductor layer, and sintering at a temperature of 150 to 250 C. in an oxygen atmosphere for about an hour. The bismuth or antimony atoms diffuse into the semi-conductor layer to provide the N-type zone, and the oxygen provides a layer of non-stoichiometric composition having P-type conductivity. In a modification, a layer of silver oxide is added to the semi-conductor layer prior to thermal treatment, to provide the P-type zone. The layers are preferably applied by vaporization. Alternatively the semi-conductor may be vaporized simultaneously with a donor and then an acceptor impurity to provide the layers of N- and P-type conductivity. The electrode is sensitive to visible, ultra-violet, and X-rays, and for the latter, the glass of the envelope 1 should preferably consist of light elements such as provided by " Pyrex " (Registered Trade Mark) glass. In operation, the PN junction should be biased in the reverse direction.

Block, rubber, and like apparatus. - In apparatus for lapping gauge blocks &c., the gauge blocks 27 are inserted in slots arranged in a circle near the periphery of a carrier disk 25, which receives a planetary motion between opposed lapping or abrading rings 4, 9. The disk is mounted on a spindle 20 driven by a pulley 22 and mounted eccentrically in a sleeve 16, to which rotary motion is imparted by worm gear 17, 18. Preferably, the spindle is driven at a higher speed than the sleeve. The ring 4 is formed with three lugs 6, in each of which is clamped a post 7; the ring 9 ia formed with corresponding lugs taking over the posts and screwed to receive screwed sleeves 12, in the ends of which are threaded screws 13. The upper ring is first placed in contact with the lower ring and the screws adjusted to abut on the ends of the posts. The ring is then removed, the carrier disk and the work placed in position, and the ring replaced with standard gauge blocks 15 inserted through slots in the sleeves 12 and nesting on the tops of the posts. The grinding then proceeds until the screws make contact with the standard gauges and the descent of the ring is arrested. In a modification, the sleeve 16 is mounted eccentrically in another rotating sleeve, and the spindle is driven through a universal joint.
