Title: Solid state microwave oscillator
IPC: H03B9/12
Filed: 1973-01-03
Abstract: 1394912 Semi-conductor oscillators; tuning resonant lines LITTON INDUSTRIES Inc 3 Jan 1973 [12 Jan 1972] 459/73 Heading H1W [Also in Division H3] In a microwave oscillator having a semiconductor element 15 capable of generating microwave energy, the element 15 is operatively associated with a resonant structure constituted by an open sided transmission line which has substantially parallel conductors 1, 3, 5 and which is short-circuited to electromagnetic energy at both its ends, the structure is mounted within a shielding housing 7, 11, 19 and 21 substantially to prevent emission of the microwave energy from the oscillator other than from an output 31 and the shielding housing contains microwave absorptive material 20 such that the housing has substantially no effect on the operating frequency of the oscillator. The length of the transmission line may be less than a quarter wavelength and as shown consists of Cr elements 1 and 5 and a Cu rod 3 insulated by mica 9, 13, 14, 23, 25, 26, 27 from A1 U-shaped parts 19, 21 and Cu plates 7 and 11 forming the housing. The plate 7 also functions as a heat sink. The oscillator element is a Gunn diode 15 and the frequency of the oscillator may be varied by adjusting the bias voltage applied from 39 to varactors 16, 17 via elements 1 and 5. The output is taken from coaxial line 35 and plates 20 of lossy, i.e. microwave dissipative material are provided to reduce the quality factor of the cavity so as to load the cavity and suppress parasitic resonances. An RC filter 38 acts to suppress bias circuit oscillations. The conductor elements 1 and 5 can be moved toward or away from the post 3 during assembly to adjust the characteristic impedance of the transmission line. In modifications (Figs. 7-9 and 11, not shown) a single conductor element (53) and a rod (51) form the transmission line and the housing is formed by an A1 shielding housing (61, 64) and Cu plates (57, 59). The conductive element (53) and the bottom wall surface of the housing (61) are suitably anodized to form an aluminium oxide layer so that the conductor element (53) and the plate (59) are insulated from the housing (61). A single varactor (65) and a Gunn diode (63) are used and the output may be taken from a coaxial cable (74). Any other semi-conductor device having negative resistance characteristics suitable for a source of microwave energy could be substituted for the Gunn diode. The introduction of the Specification indicates the use of transistors, IMPATT and tunnel diodes.

Filed: 1918-01-08
Abstract: 116,686. Lely, D., and Naamlooze Vennootschap Philips, Gloeilampenfabrieken. June 2,1917, [Convention date]. Filaments.-In a projection lamp, having filaments in the form of one or more looped coils or two or more straight coils, the coils are flattened transversely to the direction in which radiation is required. The filament may be wound on a flat round mandrel and subsequently flattened, or wound on a flat mandrel with or without subsequent further flattening. Where three or more filaments are arranged side by side, the outer ones are more closely wound, Fig. 3, to equalize radiation. Fig. 2 is an end view of the same filaments.

Title: Improvements in the treatment of viscose rayon fabrics
IPC: D06M15/423
Filed: 1962-01-05
Abstract: Viscose rayon fabrics are crease proofed, shrink proofed, stiffened and delustred by impregnating them with an aqueous solution containing a thermosetting resin precondensate, e.g. a ureaformaldehyde resin, in the presence of a mineral or organic acid or acid producing substance, e.g. ammonium dihydrogen phosphate, and curing at a temperature of from 50 DEG F. to 180 DEG F. in a pad-roll chamber or ager without loss of moisture and heat.  The fabric may be cured under conditions of temperature and humidity within the range 120 DEG F. (dry bulb) and 115 DEG F. (wet bulb) to 175 DEG F. (dry bulb) and 170 DEG F. (wet bulb).  The fabric may be stretched before being batched in the pad-roll machine.  The urea and formaldehyde may be mixed and applied to the fabric before polymerization has occurred.

Filed: 1937-01-07
Abstract: 477,070. Lubricating-pumps. STEVENS, A. H. (Cities Service Oil Co.) Jan. 7, 1937, No. 525. [Class 102 (i)] [Also in Group XXVI] In a lubricating- apparatus of the type in which a h.p. pump 9, supplied from a container 2, is operated by a fluidpressure motor 16, the motive fluid is distributed to the cylinder 16 by a valve 24, in the form of a sliding bolt having a longitudinal passage 35 and lateral ports 36. The valve slides through a chamber. 37, which comnnmicates by a pipe 22 with the cylinder 16, and the valve serves to put the chamber 37 into communication alternately with the atmosphere through a port 43 and with a compressed-air pipe 20. The pipe 20 is supplied by a hose 6, which also supplies air to the space above the lubricant in the container 1. The piston in the cylinder 16 carries a channel iron 23, which slides on a projection 25 on the valve casing. The valve 24 rests on a lever 26, which is pivoted to the projection 25, and is connected by springs 31 to the projection 23, the reciprocations of the latter thus reversing the valve. The suction stroke may be effected by a spring or, alternatively, the cylinder 16 may be double-acting. The pump 9 and the container 1 are mounted on a movable platform.

Abstract: 1405451 Retractive switches; snap action BURGESS MICROSWITCH CO Ltd 8 Dec 1972 [6 Jan 1972] 536/72 Heading H1N The actuating mechanism of a snap-acting reactive switch includes an intermediate lever 20 pivoted at 24 between the side walls of the switch housing with its free end 26 located beneath the flange 30 of a slidable actuator 22 which projects from the housing. Projection 28 on the lever engages a tension spring 14 intermediate its length, the spring being attached at one end to an upstanding post of a fixed anchor member 2 and at the other end to a movable contact arm 6 which is then held in pivoted bearing engagement at 8, 10 with a projecting part of the anchor member. In the rest position of the switch the spring is slightly deflected by the projection to provide a restoring force to the actuator and to retain the movable contact arm 6 in engagement with a fixed contact 16, and when the actuator is depressed the spring is further deflected to an overcentre position so that the movable contact arm snaps over to engage a further fixed contact 18. The length of the lever 20 and the position of the projection 28 can be varied to suit the operating force requirements.

Abstract: The invention comprises D 1: 4-3,11-diketosteroids of the pregnane series having the general formula <FORM:0823940/IV (b)/1> in which R is a hydrogen atom or an acyl radical, and processes for the preparation of D 1:4-3,11-diketo steroids by treating the corresponding 2,4 - dihalo -, 2 - halo - D 4-, 2,2,4 - trihalo - or 4 - halo - D 1 - 3,11 - diketo - steroids with a dehydrohalogenating agent, particularly a tertiary amine, e.g. collidine, or a nitrogenous carbonyl reagent, e.g. 2,4 - dinitrophenylhydrazine or semicarbazide, followed by hydrolysis, e.g. with pyruvic acid, or in the case of 2,2,4-trihalo steroids, by means of an alkali metal iodide. Preferred D 1: 4-compounds obtainable by the process include D 1: 4 - 3,11,20 - triketo - 17 a -hydroxy - 21 - acyloxy pregnadienes, especially the 21-acetate, propionate and benzoate.
