Title: Magnet arrangement for travelling wave tubes
Inventor: ARMSTRONG JOHN GRAHAM
IPC: H01J23/087
Filed: 1965-02-19
Abstract: 1,066,043. Travelling wave tubes. STANDARD TELEPHONES & CABLES Ltd. Feb. 19, 1965, No. 7253/65. Heading H1D. A magnetic focusing arrangement, e.g. for a travelling wave tube includes two hollow cylindrical longitudinally magnetized permanent magnets arranged in alignment end to end with like poles adjacent each other and field straighteners of ferromagnetic material having retentivity which is small compared to the magnet material positioned coaxially within each of the two magnets on either side of the junction or gap between them, the axial reluctance of the field straightener material being such that the reversal of magnetic field of the junction or gap is made more abrupt. The field straightener offers a low reluctance path to magnetic fields transverse the axis of the magnet. The field straighteners are formed by a wire helix of ferromagnetic material, e.g. iron which may be clad with copper and soldered to a supporting tube of brass.

Title: Improvements in pressure lubricators for shaft bearings
IPC: F16N7/00
Filed: 1920-03-10
Abstract: 140,392. Marks, E. C. R., (Nordiska Kullager Aktiebolaget). March 10, 1920. Force-feed lubricators.-A lubricator for feeding- oil against pressure in a bearing-casing, applicable for submerged bearings of water turbines, paper.pulp machines, &c., is provided with a container for a pressure fluid which controls the supply of oil. The pressure fluid, which may be compressed air or a liquid, is enclosed in a space above a flexible diaphragm z, Fig. 1, both sides of which are engaged by spring-pressed header stems k<1>, k<2>. The pressure in the bearing-casing c acts through an opening h<2> on the underside of the diaphragm. The pressures of the fluid and of the springs are so adjusted that, when the pressure in the casing c falls below the normal, the diaphragm z is depressed and a valve n carried by the stem k<1> opens, allowing oil to flow from a cup g through passages l<1>, l<2> to the casing c. The Specification as open to inspection under Sect. 91 (3) (a) describes also an oil cup g, Fig. 2 (Cancelled), closed by a metal disk g which is perforated by a pin p when the cup is screwed into position. A container s of compressed gas is enclosed in the cup, and the gas issues from openings u and acts directly on the surface of the oil. This subject-matter does not appear in the Specification as accepted.

Abstract: 622,281. Gas filters. HOUDAILLEHERSHEY CORPORATION. March 12, 1946, No. 7715. Convention date, June 11, 1945. [Class 8(ii)] An air filter is made by bunching numerous strands generally lengthwise of the unit to be produced and plasticizing the fibres to bond them to each other and to a cover for the same. A bundle of two to four feet lengths of sisal or metal fibres are first carded into a broad, flat mat. The fibres are then fireproofed, rolled, dried and plasticized before being packed into an oversize mould, or being wound with paper to form a tubular bundle, and then bonded by baking at 250 to 300‹F. for thirty minutes The bundles may then be cut into the desired lengths, or instead of being wound with paper the bundles may be tied at suitable intervals with string and cut to form barrel-shaped units. The fibres may be given a quarter-inch crimp after fireproofing. The crimped fibres are then recarded, plasticized and backed so that they are bonded together at spaced intervals. Specification 622,279 is referred to.

[Class 139] [Also in Group XXXIV] A shook-absorbing bearing for time indicators comprises a pierced jewel mounted in a recess in the plate of a watch movement and the pierced hole is so disposed above the points of support of such jewel that a lateral force on the spindle causes-the jewel to tilt about its lower edge, which butts against the wall of the recess, against a spring-restoring force. The jewel 3 which may be natural or synthetic or of hardened steel or a copper beryllium alloy, is of horseshoe shape in section, but cut away at 2 to allow a tilting movement and is supported on a bottom shoulder 5 of a bore in the plate 1 of a watch movement under the pressure of a spring 12 acting on a cap jewel 11 and transmitted through a ring 9 bevelled on its inside which bears on a chamfer of the jewel 3. The ratio of the diameter D of the jewel to its height H is 2/1. A shock on the spindle 8 in the direction X will cause the jewel 3 to tilt about its edge 13 as shown in Fig. 2, the spring 12 acting to return it to its normal position. The ring 9 may be provided by the setting ring of the cap jewel.

Abstract: 1495837 Seals FEODOR BURGMANN DICHTUNGSWERK 25 Feb 1975 [1 March 1974] 7897/75 Heading F2B In a face seal, a guide ring 56, for liquid coolant, has a narrow radial clearance with non- rotary seal ring 20 and spacer means 63 to maintain a constant axial clearance from carrier ring 40. Alternatively, the guide ring (5611, Fig. 3, not shown) may be secured to the carrier ring (40<SP>11</SP>). The throttling effect, of ring 56, on coolant flow is used to reduce the interfacial sealing pressure, at high shaft speeds, so as to avoid overheating. As the pumping action of grooves 22, 23 is increased with increasing shaft speed, the liquid pressure against face 56c increases, so as increasingly to counteract the force of springs 46.
