Title: A process for obtaining an alloy for use in modifying the physical and chemical properties of gold and silver
IPC: C22C1/02
Filed: 1961-02-03
Abstract: An alloy consists of: .Co.0.25- 2.5% .Ni.0.26-10% .Cu.up to 80% .Zn.up to 50% and is prepared by melting the metals, the heating being continued until the mixture is just molten, and then casting the melt.  The nickel and copper are added in the form of grains not exceeding 1 mm. in size.  0.05-5% of Ti enclosed in a nickel sheet may be added to the superheated melt under an inert gas prior to casting.  The ingot from the above process is then added to a melt of indium and silver to give the final master alloy for modifying the physical and chemical properties of gold or silver containing 4-40% In and 25-50% Ag (based on the final alloy).

Title: Improvements in or relating to fluid pressure apparatus
Inventor: WOOD OLIVER WENDELL
IPC: F16J10/02
Filed: 1954-02-12
Abstract: 746,696. Dashpots. NATIONAL PNEUMATIC CO., Inc. Feb. 12, 1954, No. 4203/54. Class 108 (3). The invention relates to fluid pressure apparatus comprising a piston 38 reciprocable in a cylinder 11 connected by fluid flow means with a fluid supply. According to the invention, the fluid flow means comprises a normally-open comparatively unrestricted passage 64, a comparatively restricted passage 62<SP>1</SP>, and cushioning means 40 carried by the piston, and effective when the piston nears the end of its stroke, to close the passage 64 and render operative the passage 62<SP>1</SP>. The passage 62<SP>1</SP> can be adjusted by a valve 62. The cushioning means 40 comprises a sleeve 40, slidable on the piston rod 12 against a spring 37, and engageable with a seat 66 to close the passage 64 near the end of rightwards piston travel. The piston 38 has fibrous lubricating rings 31, lubricant-retaining channels 32, and packing rings 51 and 52. Each cylinder head is sealed by a non-metallic ring 14, and a toroidal spring 16. Clamping nuts 17 can be slackened off to enable the rotational position of the cylinder to be adjusted. The brackets 23 at each end of the cylinder are reversible to enable various combinations of positions of their securing holes to be attained.

Title: Anti-vibration bearings for the shafts of a centrifugal gas separator
IPC: B04B9/14
Filed: 1958-02-10
Abstract: 843,715. Bearings. BEYERLE, K. Feb. 10, 1958 [Feb. 20, 1957; and Jan. 23, 1958], No. 4210/58. Class 12 (1). In a centrifugal gas separator having a drum 1 which is accommodated in an evacuable casing 8 and has upper and lower flexible stub shafts 2 connected respectively to the rotor 3 of a driving motor 4 and a journal 5 mounted in bearings in an end plate 7 of the casing each shaft 2 passes, adjacent the drum 1, through a displaceable bush 9 of an anti-vibration bearing. Fig. 1 shows a known type of bearing arrangement in which each bearing 9 is located in a plate 10 which frictionally engages a support 11 rigidly secured to the casing 8. Fig. 2 shows a bearing in which the bush 9 has integral and pivotally mounted radial arms 12, 12a respectively, which slidably engage sockets 15, 15a and divide the casing 13, having a cover-plate into four oil chambers 17a-17d. Admission of oil into the chambers 17a- 17d is restricted by a throttle 17e so that oil displacement, from chamber to chamber, within the casing due to cyclic vibrations f, Fig. 1, caused by unbalance of the drum, cannot be replaced immediately and small air cavities 17a<SP>1</SP>, 17c<SP>1</SP>, 17d<SP>1</SP> are created and removed in sympathy with the vibrations f until the oil displacement is balanced by a readmitted volume of oil. The oil, offering comparitively little resistance to the out-of-balance vibrations f, has the necessary damping resistance to a slower vibratory movement of the bush due, e.g. to the drum precessing. Frequency dependent damping forces can also be obtained by using oil-soaked packings of porous yielding material which require a certain minimum time to soak themselves full of oil. Additional elastic means, either in the form of a number of springs interposed between the shaft 2 and the bush 9 or in the form of a number of bubbles in the bearing oil, may be incorporated in the bearing to accommodate the vibrations f of the drum. Alternatively the rigid arms and sockets 12, 12a, Fig. 2, may be replaced by spring steel flexible plates, or elastic membranes may be incorporated in the walls of the housing 13. In a further modification, Fig. 10, the shaft 2 loosely fits within the inner race 24 of a ball-bearing, plates 25 around the shaft 2 being urged by a spring 28 to -frictionally engage the race 24. In a still further modification a flexible plastic packing is introduced between the end of each shaft and the corresponding end plate of the drum 1.

Fillers, such as finely dispersed silica, organic or inorganic pigment, dyes and flame-proofing agents such as antimony trioxide and polyvinyl chloride may be present in the layers.  The coatings may be applied to metals, paper, textiles such as cotton, jute, linen, regenerated cellulose, polyesters, polyacrylonitrile or polyamides, e.g. woven polyamide fabric.  The coatings may be applied to one or both sides of the fabric or the inside may be coated with another plastics material such as a polyester.

Title: Control apparatus for responding to a fault current in a power transmission line

Filed: 1976-02-09
Abstract: 1535124 Recognizing fault currents HUGHES AIRCRAFT CO 9 Feb 1976 [6 March 1975] 04948/76 Heading H2K In a system for recognizing the occurrence of a fault on a line within a fraction of a cycle, in which when the line current rises above its normal maximum level a reference fault waveform is generated for comparison with the actual current waveform, the reference fault waveform is given a shape dependent on the function  where the line voltage is given by # = V sin #t, k<SP>1</SP> is a constant representing line impedance, t 1  is the time at which the excessive current was first detected, and # is zero for single phase faults but 150 or 210 degrees as appropriate for faults to other phases.  The system of Fig. 4 detects single and two phase faults for a given phase # 1 , similar systems also being provided for the other two phases. An oscillator 36, phase-locked to the line voltage except when a possible fault current waveform is under investigation, produces the three-phase outputs shown, and summing amplifiers b, c then derive cos(#t + 150 degrees) and cos(#t+210 degrees) signals. These latter signals and the cos #t output from the oscillator are normally applied to both inputs of respective differential amplifiers a, d, e which thus produce zero outputs. When the line current Il exceeds a threshold k, however, switches S1 are opened, holding the lower input of each amplifier a, d, e to the value of its input signal at that instant (e.g. cos #t). Thus these amplifiers now generate the functions indicated above. An offset equal to the threshold k is added to each amplifier output (not shown in Fig. 4) to create reference waveforms which are compared with the actual current waveform Il. If, over a further short time, the latter exceeds the reference an output is given, though for possible two-phase faults the output is blocked (51<SP>1</SP>, 51<SP>11</SP>) unless the current on the other phase has also the exceeded threshold. The output may actuate a current-limiting circuit breaking arrangement as in Specification 1,517,551.
