Patent GB-312986-A (GB)
IPC: F16F9/14
Filed: 1929-01-14
Abstract: 312,986. Logan, H. H. June 4, 1928, [Convention date]. Fluid-friction vibration-dampers.-In apparatus of the type in which radial vanes oscillate in a cylinder having radal partitions, a reservoir for liquid is disposed about a bearing at one end of the casing and having a shaft carrying the radial vanes, the working chambers being separated from the reservoir by a partition carrying the radial partitions. A casing, Figs. 2 and 3, is bolted to the vehicle frame and the shaft 29 carries at its outer end an operating-lever connected by a link to the axle. The shaft 29 works in a bearing 27 surrounded by a reservoir 60 which is separated from the working chambers by a partition 42 integral with the three radial partitions 45 which form three working chambers. The shaft 29 oscillates three radial vanes 83 and the back end of the casing is closed by a plate 67 having a spigot 80 engaging a socket in the end of the shaft. The transfer of liquid between adjacent compartments takes place through three distinct passages. Small holes with one-way valves are provided in the partitions. Tapered circumferential grooves in the casing are made deep at the middle part 129 and shallow at the ends 128, so that the resistance to movement of the frame relatively to the axle may be small for small displacement from the normal position but large for greater displacements. The flow of liquid through pairs of radial connecting passages 126 and 127 in the shaft 29 may be regulated to vary the resistance by rotary adjustment of a spindle 108 in the shaft 29. The enlarged inner end of the spindle is formed with three grooves 120, 121, 122 of varying depth spaced circumferentially at 120 to one another as shown also in Fig. 8. The spindle 108 may be adjusted relatively to the shaft 29 by means of a knurled knob 116 and the passages 126, 127 may thereby be completely closed or opened to any desired amount. 'The upper end of the reservoir may communicate by a small hole with the upper working chamber so as to allow escape of air into the reservoir and the lower end of the reservoir supplies oil to one of the lower chambers through a one-way valve to make up leakage.

Abstract: 631,677. Girders; floors; roofs. ANDREWS, W. C., and HOENIG, E. Jan. 15, 1947, No. 1360. [Class 20(iv)] A precast concrete girder of inverted channel shape has oppositely facing channel portions of substantially the same shape, separated from the main channel by inclined transverse walls, at one or both ends, the flat base of these portions forming end bearing surfaces for the girder, so that when two girders are placed end-toend with these surfaces resting on a concrete support, concrete may be cast into the recess formed by the upwardly facing channel portions to form a T-beam and a monolithic joint between the girders and support. In the form shown, the girders are of sections as in Fig. 4 and are shaped at one or both ends to present upwardly facing channel portions 14, as in Figs. 1 and 2, a transverse wall 15 separating channels 14 from the main channel. When two girders are placed end to end, concrete may be poured into the channels 14 to form a monolithic joint with the support beam 19. This concrete may be reinforced by members 17 and 20. The other ends of the girders may be of the same form or they may be tapered or rebated, Figs. 3 and 6 (not shown), to fit alternative forms of supporting members. Floors and roofs are formed by positioning the girders side by side and flanges 10 may be formed along the sides of the girders so that concrete 12 may be cast into the troughs between them to give a monolithic surface.

Abstract: 1,181,219. Cathode-ray tubes. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 11 Jan., 1967 [28 Jan., 1966; 3 March, 1966], No. 1458/67. Heading H1D. A cathode-ray tube comprises a vacuum envelope with a neck portion 411 housing an electron gun and connected to the widened tube portion 415 at a point remote from the target end of the neck portion so that the latter projects into portion 423. An electrostatic accelerator lens of high refractive power is formed by an annular first electrode 421 in the projecting neck portion and an annular second electrode 418 mounted in the widened tube portion. These electrodes may be wall coatings or metal cylinders and are preferably axially symmetrical. First electrode 421 may have flange-like, annular or diaphragm-like extensions. Electrode 418 may cover wholly or partially the conical portion of the wall and preferably, the screen and cathode ends of electrodes 421 and 418 respectively overlap and similarly the screen end 420 of the projecting neck portion and the cathode end of the second electrode may overlap. Further electrode 414 serves to extract electrons from the gun region allowing a lower potential on electrode 421 to increase the refractive power of the first and second electrode lens combination. Also the potential dip at electrode 421 repels slow secondary electrons from the deflector plates. The projecting neck portion may be of reduced diameter (Figs. 2, 3 and 6, not shown). In Fig. 5 (not shown), a lens (53) such as a unipotential lens, produces an intermediate image (56) smaller, the same or up to twice the size of the cross-over point (52). The deflector plates are preferably between the image forming lens (53) and the accelerator lens (57). C.r.t.'s with luminescent screens and storage electrode targets are mentioned.

Filed: 1919-01-22
Abstract: 141,816. Zweigbergk, T. Jan. 22, 1919. Master control systems.- In a master control system with resistance contactors operated by an auxiliary electric motor, a separate contactor controls the main circuit, and the auxiliary motor is reversed by a switch operatively connected with the controller. The motor A rotates a cam shaft for the operation of levers to close the contactors controlling the resistance sections Q in series with the main motor R, and is connected to the brushes W which wipe over reversing-contacts M - - M<4> on the arm N of the contactor which operates the contact J<2> in the main circuit. When the controller U is moved to its closed position, the solenoid L is energized to raise the contact J<2> and so start the motor R. The reversing-contacts M - - M<4> are operated at the same time, and the auxiliary motor runs in the direction to cut out resistance. If the current in the motor R is excessive, the relay G closes the contacts X, Y and short-circuits the armature of the motor A, thereby stopping the cutting-out of the resistance Q. When the controller U is moved to the stop position, the contact J<2> drops and opens the main circuit. The contacts M - - M<4> also drop and reverse the field S of the motor A; this motor then runs to insert the resistance Q. The auxiliary motor is always in circuit when the line is energized, and its movement is limited by stops.

Abstract: 1494716 Proteinaceous foodstuffs M A STAHMANN 20 Jan 1976 [23 Jan 1975] 02108/76 Heading C3H A process for coagulating and preserving proteins from the juices expressed from the stems and leaves of green plants comprises holding the freshly expressed juices in an anaerobic atmosphere for a predetermined length of time to form organic acids from carbohydrates in the jiuces and utilizing the microorganisms carried into the juices from the leaves of the green plants on which said micro-organisms are naturally resident to effect anaerobic fermentation of the juices and the consequent lowering of the pH of the juices to increase the acid content of the juices and thereby coagulate the proteins in the juices. Specified plants are alfalfa, corn, oats, lawn clippings, pangola grass, brown grass, elephant grass, pea vines and sudan grass, the juices of which should have a pH up to 6 and not less than 3À4. The process destroys undesirable chlorophyll and saponinglycosides but converts soluble carbohydrates and non-proteinaceous nitrogen into bacterial protein. Thus cystine and methionine increase the amino acid content and hence the food value of the juices.

Abstract: 833,127. Magnetic drum data-storage apparatus. FERRANTI Ltd. Jan. 22, 1958, No. 2111/58. Class 106 (1). [Also in Group XXXIV] A magnetic drum for data storage having a frusto-conical outer surface and an inner cylindrical bore closed at one end by which it is guided, by means of a gas bearing, on a vertical cylindrical mount with the end of greater diameter uppermost, is moved upwardly if and when the gas pressure in the bearing falls below a predetermined value. The arrangement is such that the clearance between the outer surface of the drum and the reading and/or recording heads is rendered greater than the clearance between the inner surface of the drum and the mount so as to prevent the possibility of contact between the heads and the drum. In the arrangement shown, the drum 12 is driven by a motor 21a through a friction clutch 1.2a. The drum is supported by the clutch and is guided relative to the cylindrical mount 10 by air passing through apertures 18 from a chamber formed between the cylinder 10, an inner cylinder 17 and rings 16, and supplied by a line 14. The air is also supplied from the line 14 to a cylinder 21 in which moves a piston 22 on the motor shaft. The pressure is normally sufficient to hold the motor and drum in depressed operative position, but if the pressure falls, a spring 24 raises the motor and drum until a stop 25a engages the top wall of the cylinder 21. The drum is then unable to contact the heads 20 as a result of lateral movement on its mount. Specification 778,112 is referred to.
