Title: Non-destructive testing for flaws
IPC: G01N22/02
Filed: 1980-01-18
Abstract: The invention relates to non- destructive testing for flaws in the surfaces of, particularly, billets, strip or sheet in which plane-polarised microwave radiation from transmitter 1 is directed at a surface 3 to be scanned and plane-polarised micro-wave radiation reflected from the surface 3 is detected by receiver 2, the polarisation directions of the transmitter and the receiver being perpendicular to each other. The polarisation directions of transmitter and receiver may be positioned at an angle of 45 DEG  to the likely flaw 10 direction. A reference signal may be passed directly from the transmitter to the receiver so that the output of the latter may be represented as a one dimensional holographic signature. The transmitter and receiver may be combined in a single unit and scanned across the surface. <IMAGE>

Title: DC-DC Converter
IPC: H02M3/10
Filed: 1980-08-05
Abstract: A DC-DC converter includes an auxiliary, self-oscillating, converter (9), which provides power during switch on and off of the converter, i.e. under fault conditions. On switch on, this converter (9) drives the control and protection circuitry (2, 3, 6, 5) for the main converters (1, 8) until the main converters reach their operating state. When this occurs, the auxiliary gate (4) via which the auxiliary converter (9) provides the above-mentioned drive, switches over so that the control and protection circuitry are now powered from the main converters. it also, via the connection shown, disables the auxiliary converter (9). Under fault conditions, operation is, as it were, similar but in reverse. The arrangement shown is a "double forward" type arrangement with positive and negative outputs, but the invention is also usable with other types of converters. <IMAGE>

Title: Device for Transmitting Rotary Motion at Changed Speed
IPC: F16H1/32
Filed: 1981-09-16
Abstract: In a simple construction, the device comprises n balls (54) (where n is a multiple of four) meshing in a wavy groove (55) having (n-1) or (n+1) waves in a male member (47), the balls being engaged also in n arcuate grooves (56) in a female member (57) fast with output shaft (44). The male member (47) is secured against rotation by universal joint (49-52) and is swashed by swashplate (45) fast with input shaft (41), the balls processing along the wavy groove to transmit rotation at reduced speed to the output shaft. Cage (59) keeps the balls in a medium plane swashing at half the angle of swash of the male member. In other embodiments, the balls mesh in wavy grooves in both members, and both members may be swashed but in opposite directions. The grooves may be of varying depth to ensure pure rolling of the balls. Rotatable pins replace the balls in some embodiments. Angled drive couplings of fixed or variable angle and of swashing or non-swashing type are also disclosed, as is a drafting machine for generating the forms of various wavy grooves. A device providing dual contra-rotating outputs or a number of stepped speed ratios is also described (Fig 24, not shown). <IMAGE>

Title: Biscuit manufacture
Inventor: WADE PETER
IPC: A21B2/00
Filed: 1983-08-16
Abstract: A biscuit oven or oven stage has near infrared radiation sources 15 providing radiation having maximum intensity in the wavelength range 0.72 to 2.00  mu m and a conveyor belt 6. To reduce emission of secondary radiation of wavelength between 2  mu m and 6  mu m, the oven walls are cooled by air sucked into a duct formed by outer walls 30,32,34 by a fan 36. The reduction of secondary radiation emission results in an improved biscuit with an appropriate inner structure and also reduces the tendency for baked biscuits to break spontaneously when stored after baking. After exposure to infrared radiation in said oven or oven stage, the biscuits may be exposed to similar radiation in a further oven stage in which the oven walls are not cooled, whereby secondary radiation emitted from the wells effects browning of the biscuits. <IMAGE>

Title: Circuit arrangement for digitizing and storing color video signal
Inventor: TANAKA HIDESHI
IPC: H04N9/808
Filed: 1983-10-28
Abstract: An input composite color video signal is processed to derive a luminance signal (Y) and three primary color signals (R, G, B) first, and then only a high frequency component (YH) of the luminance signal is A/D converted by a first A/D converter 18, while only low frequency component (RL, GL, BL) of each of the three primary color signals is A/D converted by a second A/D converter 30 with the low frequency component of the three primary color signals being time- shared by a first switching circuit 28 to be a single analog signal. The A/D converted chrominance information is fed to a second switching circuit comprising shift registers 32, 34, 36 of parallel-in and serial-out type so that three bits respectively indicative of red, green and blue signals are simultaneously outputted therefrom. The A/D converted luminance data of a plurality of bits, and three bits indicative of three primary colors are simultaneously written into a memory 20. <IMAGE>

Title: Electrical conductor sealing member
Inventor: LOTHMANN WERNER
IPC: H01R13/52
Filed: 1984-02-15
Abstract: The sealing member, which is for use in providing sealing at the position of entry of electrical conductors into an electrical connector housing comprises a body of resilient material consisting of two parts (1 and 2) which are formed integrally with hinges (3) which enable the two parts to be relatively moved between an open and a closed position. In the closed position of the parts (1 and 2) they define holes (7) for receiving an electrical conductor in sealing relationship. In the open position of the parts (1 and 2) they are so spaced that an electrical terminal terminating a conductor can be passed between the two parts (1 and 2).

Title: Preparing a water-in-oil emulsion containing a water-soluble polymer
Inventor: DOMINA WILLIAM GLENN
IPC: C08F20/52
Filed: 1984-02-28
Abstract: A method for preparing a concentrated stable water-in-oil emulsion containing at least 40 weight percent of a water-soluble polymer which comprises the steps of (1) forming a stable water-in-oil emulsion containing at least one water-soluble monomer in an aqueous phase which is dispersed in a continuous oil phase, said emulsion of monomer containing an emulsifying amount of a water-in-oil emulsifier; (2) subjecting the emulsion of monomer to conditions sufficient to polymerize the monomer thereby forming a stable water-in-oil preconcentrate emulsion of a water-soluble polymer; and (3) concentrating the emulsion by removing at least a portion of the water from the preconcentrate emulsion, and adding, prior to or during step (3), an inverting surfactant in an amount sufficient to reduce the bulk viscosity of the preconcentrate emulsion, but less than that which destabilizes the preconcentrate emulsion or the concentrated emulsion. The concentrated emulsions prepared by the process of this invention are superior to conventional emulsions in that they have increased polymer solids, reduced oil content, lower bulk viscosity and greater stability than are characteristic in the conventional emulsions containing about 30 weight percent of solids. In addition to their utility as additives in drilling muds, fracturing fluids and fluid mobility control agents in enhanced oil recovery methods, the emulsions prepared by the process of the present invention are also useful in flocculating agents for sewages, industrial wastes, mining streams such as coal slurries and mining effluents, as thickeners for coating formulations and as additives for the manufacture of paper.
