Abstract: 580,918. Securing machines to foundations. DUNLOP RUBBER CO., Ltd., WILSON, H., and GRAY, T. E. H. Dec. 9, 1944, Nos. 24716/44 and 19238/45. [Class 80 (iv)] [Also in Group XXXII] A machine 2 or the like is attached resiliently to a supporting base 3 by a pad 1 of resilient material, such as rubber, which is located between the machine 2 and the base 3 and has an extension 4 entering an aperture 5 in the base, the extension 4 being compressed after assembly, such as by a bolt 7, so that it grips the walls of the aperture. A sleeve may be mounted on the bolt to limit the amount of compression. In a modification, the pad has an upper extension entering a hole in the machine frame, the upper extension being compressed simultaneously with the lower extension. In another modification extensions 4, 11, Fig. 17, on the pad 1 are initially longer than the accommodating recesses 5, 12, but are compressed by the weight of the machine to grip the walls of the recesses 5, 12. The upper extension may be omitted. In another modification, the extension on a pad enters between the side walls of a pair of girders and is compressed by a pair of bolts acting on a cross bar. In another modification the nut 8 and bolt 7, Fig. 2, is replaced by a T-bolt. As shown in Fig. 13 the extension 4 is compressed by forcing a bolt 19, shaped as shown, into a hole in the pad 1.

Abstract: 666,365. Converting. ERICSSON TELEPHONES, Ltd., MITCHELL, J. H., DISTIN, L. S., and WILMAN, C. V. Sept. 21, 1950 [Sept. 27, 1949], No. 24760/49. Class 38 (ii). An A.C. load such as a fluorescent lamp LP with starting inductor LC is supplied from a D.C. source X1, X2 through interrupter contacts CR driven by a rotary electric motor M, in series with a capacitor C, a linear inductor LA and non-linear inductor LB. When the interrupter contacts make and break, the non-linear inductor LB becomes unsaturated and rises in value to reduce the load current, but during the remaining time the inductor LB is saturated and has negligible inductance, the load current following a sine curve determined by the seriesresonant capacitor C and linear inductor LB. The interrupter contacts CR may comprise rotary or reciprocating moving contacts. There may be a transformer TR between the impedance elements and either the interrupter or the load. The connection of the load to the supply may be retarded by a relay circuit until the motor M has reached full speed, Fig. 4 (not shown). Similar arrangements in which the interrupter is of the vibratory type are described in Specification 637,938. The output voltage may be rendered less sensitive to changes in the D.C. input by a saturable reactor with a winding carrying current taken direct from the input as described in Specification 628,208. Specifications 632,469 and 641,019 also are referred to.

Patent GB-799349-A (GB)
Title: Manufacture of grease
Filed: 1955-08-31
Abstract: A method of making lubricating grease, which method may be operated continuously, comprises subjecting a heated fluid mixture, comprising soap or other thickening agent in a condition wherein it does not possess a greaseforming crystalline structure and mineral lubricating oil or other oleaginous vehicle, to mechanical atomization into mist-like particles and instantaneously contacting the particles directly with a substantially cooler surrounding atmosphere, thereby forming grease particles in which the thickening agent possesses the desired crystalline structure.  The mixture of soap and lubricating oil may be prepared by the reaction between fatty materials, such as fatty acids or glycerides, and metal-containing saponifying agents, such as lime, sodium hydroxide or lithium hydroxide monohydrate, in the lubricating oil.  Water, light hydrocarbon, a volatile oil fraction or other vaporizable material may be present in the mixture before dispersion into particles and, as a result of this dispersion, part or all of this material may be vaporized.  The mixture may be dispersed by passage through an atomizing nozzle and the grease particles may be collected and deaerated.  Additional lubricating oil may be added to the grease. Additional ingredients such as phenyl alphanaphthylamine and extreme pressure agents may be added at some stage in the preparation of the grease.  Apparatus for carrying out the preparation of the grease is described.  In the examples, greases are prepared according to the process of the invention from mineral lubricating oil and (1) palmitic acid, stearic acid, oleic acid, lithium hydroxide monohydrate and lime; (2) myristic acid, palmitic acid, stearic acid, oleic acid, hydroxy stearic acid, C20 and C22 fatty acids from hydrogenated fish oil, glycerine, lime and sodium hydroxide; (3) tallow, candelilla wax, glycerine, acetic acid and lime and (4) tallow, lard oil, hydrogenated tallow and sodium hydroxide.  For comparison purposes, the preparation of greases from the same ingredients using conventional procedures is described.

Filed: 1954-08-31
Abstract: 758,607. Dashpots. DILLEN, A. VAN. Aug. 31, 1954, No. 25222/54. Drawings to Specification. Class 108 (3). [Also in Groups XXV and XXVI] The check cylinder of a door-closer (see Group XXV) may have a stepped bore and the piston a conical form, not fitting closely therein to allow the restricted passage of oil; the checking effect may be varied by longitudinal adjustment of the cylinder in relation to the piston. In a modification the piston and cylinder are cylindrical and the piston carries a rubber ring which can be compressed axially between a flange of the piston and a ring screwed on the piston body to vary the outside diameter of the piston, thus avoiding the need for accurate dimensioning of the parts. The piston has a passage parallel to the axis, in which a tapered valve rod rests freely, this rod being moved into contact with one end or the other of the cylinder, to open or restrict the passage, by the fluid pressure built up by movement of the piston towards the opposite end; the taper causes progressive increase of checking action during closing of the door. The cylinder end through which the piston rod passes may be sealed by bellows connecting it to the piston or by a rubber disc clamped at its circumference at a short distance from the cylinder end (see Group XXVI).

Title: Improvements in or relating to automatic gain-control circuits-arrangements in television receivers
IPC: H04N5/52
Filed: 1951-11-06
Abstract: 698,715. Television. PHILIPS ELEC. TRICAL INDUSTRIES, Ltd. Nov. 6, 1951 [Nov. 9, 1950], No. 25932/51. Class 40 (iii) [Also in Group XL (c)] In an automatic gain control (A.G.C.) circuit for a television receiver demodulated signal is fed to the control grid of a valve having a bias derived from its output, so as to stabilize the peak value of the alternating voltage in the output, and an A.G.C. voltage is produced in accordance with this grid bias when it exceeds a predetermined value. Signals in which peak outward modulation comprises the synchronizing pulses are rectified by a detector 2 and applied to the grid of a valve 6, direct coupled to a peak rectifier 10. Grid bias for the valve 6 is obtained from an adjustable potentiometer 14, being derived in part from a negative supply line and in part from the output of the rectifier 10. In this way the peaks of the synchronizing impulses are stabilized at a predetermined point near the foot of the valve characteristic, Fig. 2 (not shown), irrespective of the signal level, and the effect of noise impulses, which extend beyond cut-off, rendered negligible. A further valve 16 obtains bias from the potentiometer 14, a cathode bias being also provided, by means of resistances 17, 18 so that this valve is cut off until a sufficient positive-going output is obtained from the rectifier 10. Conduction in the valve 16 reduces the anode potential correspondingly, so that a control bias suitable for A.G.C. purposes may be derived from a potentiometer 20, 21 connected between the anode and the supply line. The resistance 18 may be made adjustable and utilized as the contrast control. In order to avoid working over the tail of the characteristic of the valve 6 a clamping diode 9 is connected across the resistance 8, the point at which it comes into operation being determined by a positive bias derived over resistance 12. In a modification, Fig. 3 (not shown), the peak rectifier 10 comprises a triode, separated synchronizing impulses being obtained from its anode circuit.
