Abstract: 1280178 Measuring electrically BISSETTBERMAN CORP 19 Sept 1969 46365/69 Heading G1N [Also in Division G4] Apparatus, Fig. 1, for measuring electrically a non-electrical variable comprises a first capacitor 16 in series in the input to the combination in parallel of an operational amplifier and a second capacitor 10, the operational amplifier including a basic amplifer 26, being of high input impedance, low output impedance and high open loop gain and one of the capacitors being responsive to the non- electrical variable. The two capacitors are enveloped in electrostatic shielding 60. Capacitive transducers are illustrated for measuring pressure, displacement or temperature, Figs. 2, 3, 4 (not shown), and acceleration, Fig. 5 (not shown). An A. C. output signal may be taken from the terminal 32 or a calibrated decade resistor may constitute reference 36 when an A.C. null detector is connected to the junction 38. In an alternative embodiment, Fig. 8 a capacitive sensor as in Fig. 1 is included as a four-arm bridge network 300 which forms part of the frequency determining circuit of an oscillator. The amplitude of the output voltage Eo from the network 300, varies as the non-electrical variable, and is summed in an amplifier 306 with the voltage Eq from a network 304 which latter voltage is in phase quadrature with respect to the input voltage Ein. The oscillation frequency is that at which the sum of the phase difference between Ein and the resultant Er (of the voltages Eo and Eq) and the phase shift introduced by the network 308 equals 180 degrees.

Title: Well logging data processing techniques

Filed: 1972-05-04
Abstract: 1432336 Well logging-digital computer applications SCHLUMBERGER Ltd 1 May 1973 [4 May 1972] 46557/75 Divided out of 1432335 Heading G4A [Also in Division G1] The description is identical to that of the parent Specification 1,432,335, but the claims are directed to that part of the data processing where DEPTH-SHIFTING CORRECTION is required between the data storage and retrieval (because all of the sondes are not at the same position on the logging tool) so that the recorded data can be referenced to a particular depth. Therefore, if a depth measuring point is considered to be at the lowest point on the tool and if there are three sondes respectively spaced from the lower portion of the tool by, for example, 36-inches, 54-inches and 72-inches, the various logging data must be depth shifted by these same distances if the data is to be correctly correlated with depth. Fig. 48, shows an example of how such depth shifting is accomplished, using a so-called cyclic buffer 735 which has fifteen consecutive storage locations. The in-pointer 736 points to the location where the next data acquired from a particular location is to be stored. The out-pointer 737 points to the storage location from which the next-to-be processed data will be taken. The pointers 736, 737 will be incremented by one storage location each time data is acquired and removed. Thus assuming that data is to be acquired every six inches, the logging data obtained from the sonde spaced 54-inches above the depth measuring point of the tool must be depth shifted by nine storage locations or 54-inches (9 Î 6). Therefore, a spacing of nine locations is shown separating in-pointer and the out-pointer on the storage core.

Abstract: 1445171 Transfers: etching E R NICHOLLS 3 Oct 1974 [6 Oct 1973] 46778/73 Headings B6C and B6J [Also in Division H7] Printed circuits are fabricated from an insulant substrate with a conductive, e.g. copper layer laminated thereupon by applying thereto transfer carrier sheets of transparent PVC film having representations thereon defining respective elements of the required conductors and components to be formed as printed circuits. The transfers are produced by printing the representations on the carrier sheet 15 with etch resistant layers 16 of, e.g. polythene in an evaporant solvent and overprinting with a layer of pressure sensitive adhesive 17; the transfer being overlain by a protective sheet 18 of, e.g. silicone impregnated paper and supported by a backing card 19 (Figs. 2, 3). Registering perforations 20 are provided for assembly in a binder. In preparation, the exposed surface 14 of the laminate conductive layer is abraded and the requisite circuit representation is laid out (Figs. 5, 6) by overlaying the transfer 10 with the protective paper 18 selectively removed and transfering the etch resistive pattern by local pressure, e.g. by a ball point pen. The carrier sheet is removed and the operation is repeated until the required printed circuit is defined (Fig. 8). Alternatively the individual patterns are cut out from transfer sheets and applied individually. Thereafter the plate is etched in ferric chloride to remove the unprotected conductive layer, removed, washed, and the protective layers removed to leave a complete printed circuit board (Fig. 10). Etched spots in the conductive layer reveal the insulant substrate to locate the positions for drilling through holes for soldered attachment of separate components. Specification 1,445,172 is referred to.

Abstract: 1,267,576. Moulding dough. K. H. BRUNNER. 24 Sept., 1969, No. 47007/69. Heading B5A. A dough knot forming machine is provided with dough strips S which are fed between a conveyer 60 and a plate 75 whereby they are roller into strings and delivered to a rotary vaned drum 70 from which they are fed in turn to a pivoted gate 72 whereby they are held against an inclined table 80 before being released by the gate to slide transversely down the plate to abut a hollow pin 92 whereupon the strip is formed into a U-shape. One leg of the U rests on the table and the other passes through the leg of a P-shaped aperture. The pin 92 is then moved downwardly and the dough string is received on a tying platform 113 comprising a flange on a cylinder slidable about the pin. The leg of the dough string which rests on the table is crossed over the other leg and partially wrapped around the pin by a member 138 carried by an arm 140 pivoted about the axis of a shaft 142. The other leg of the string, which is supported by a U-shaped yoke 152 on a finger 153 secured by an arm 154 to a rotary shaft 155, is then moved by the latter to bring it across the end of the hollow pin 92 where it is retained by a negative air pressure applied thereto which draws the string partially into the mouth of the pin. The platform 113 is then raised to or slightly beyond the end of the pin and the negative pressure retained whilst the string is forced upwardly; a positive air pressure is now applied to the pin to eject the knot from the platform whereupon it slides down the table to a conveyer belt 51. Positive and negative air pressure is provided by a vacuum pump 127 driven by a motor 128 and connected via suction and pressure lines 129, 131 to a 4-way valve 130. The parts 138, 113 and 92 are then returned to their initial positions. Operation of the machine parts is effected by a motor 23 which drives a shaft 24 carrying a number of cams 27a-27f, each controlling the movement of machine parts 72, 92, 113, 130, 138, and 152 via separate linkage mechanisms.

Title: A process for obtaining cyclohexanone oxime
Filed: 1962-12-20
Abstract: Cyclohexanone oxime is produced by treating 2-chlorocyclohexanol oxime with molecular hydrogen in the presence of a hydrogenation catalyst in an inert solvent in a medium sufficiently acid to neutralize the basic by-products of the reaction, which may be effected at -10 DEG  to 80 DEG  C. at atmospheric pressure.  The reaction medium may be given the desired degree of acidity by (1) the inclusion in the reaction mixture of buffering or neutralizing agents or (2) the addition of a strong acid, preferably in a proportion less than equimolecular with respect to the starting material. Alternatively, the medium may become sufficiently acid by reason of the hydrogen chloride liberated in the reaction.  A number of suitable solvents are specified. The specified neutralizing or buffering agents include sodium acetate, sodium carbonate, triethanolamine, tributylamine and cyclohexanone oxime itself. Examples are given.

Abstract: 1449036 Laminated pipe wrappings AUTOMATION INDUSTRIES Inc 16 Oct 1973 [18 Dec 1972] 48149/73 Heading B5N [Also in Division F2] A flexible wrapper for a warm air duct consists of one layer of stretchable material proof against vapour, reinforced by material which allows stretching in at least one direction. The reinforcement protects the wrapper against tearing &c. In one form, a plastics film of, e.g. P.V.C., polyester, C.P.E., 55, Fig. 3, is reinforced by two sets of threads 65A, 65B at right angles, bonded or laminated to the film. The threads 65A, 65B may be individually applied or may be in the form of a fabric. The arrangement of the threads 65A, 65B permits stretching both lengthwise and transversely of the strip of film. In a modification, a third set of threads (71R), Fig. 4 (not shown), extends lengthwise of the film, to prevent lengthwise stretching while permitting transverse stretching, as before. Alternatively, the third set of threads (71A) may be slightly stretchable, to allow limited lengthwise stretching. The threads 65A &c. may be single filaments or twisted yarns. In another form, only threads (51C), Fig. 5 (not shown), extending lengthwise of the film, are provided. Five other alternative forms, Fig. 6, each have a fabric with transverse and longitudinal threads laminated to a plastics film. Either a crimped &c. yarn set 77, 79, 81, 83, which may be twisted, or a stretchable yarn 85, arranged transversely of the film, allow stretching in that direction. In a final form, the plastics film is laminated to a non-woven reinforcement, Fig. 7 (not shown), e.g. of polyester, polypropylene or polyolefin, having similar stretch properties.

Title: Recording distance measuring device attached to a vehicle hub
IPC: G06M3/12
Filed: 1976-11-30
Abstract: The device allows the distance travelled, for example by a heavy goods vehicle on a journey, to be recorded by inserting a clock card into a card slot (4) at the beginning and end of the journey. The counting mechanism of the device has a series of digit print wheels (19) on one axis (54) and, on an axis (55) parallel to the latter, a series of transmission pinions (62) for the decimal carry. To prevent the digit print wheels (19) from being able to be adjusted through manipulation by means of a tin plate (56) inserted into the card slot (4), one end (74) of the axis (55) of the transmission pinions (62) is spring-clamped in a carrier (58). If an attempt is made to adjust the digit print wheels by means of the tin plate (56), the axis (55) is pushed out from its bearing. The digit print wheels can then rotate freely and produce an irregular, flawed impression on the clock card, thus allowing the unauthorised intervention to be detected. <IMAGE>
