Abstract: 1,153,924. Isoprenoid compounds. F. HOFFMANN-LA ROCHE & CO. A.G. 27 Jan., 1967 [28 Jan., 1966], No. 60559/68. Divided out of 1,153,923. Heading C2C. Isoprenoid compounds of the general formula wherein R 5  represents an acyl group and R 6  represents the formyl or carboxyl group and wherein the broken line denotes an optional bond are prepared by subjecting a compound of the general formula wherein R 1 , R 2  and R 3  each represent an alkyl group or R 1  and R 3  together represent a trimethylene group and R 4  represents an alkoxy group, to acidic hydrolysis and, if desired, acylation. Examples describe the preparation of 2,6 - dimethyl - 8 - hydroxy - octadien - (2,6) - yn - (4) - al - (1) which can be partially hydrogenated to give 2,6 - dimethyl - 8 - hydroxy - octatrien - (2,4,6) - al - (1), and 2,6 - dimethyl - 8 - hydroxy - octadien - (2,6) - yn - (4) - oic - (1) acid which can be partially hydrogenated to give 2,6 - dimethyl - 8 - hydroxy - octatrien - (2,4,6) - oic - (1) acid, which are valuable for the synthesis of polyene compounds.

Title: Radio meters
IPC: G01R29/08
Filed: 1970-12-30
Abstract: 1325920 Automatic gain control SPERRY RAND CORP 30 Dec 1970 [8 Jan 1970] 61713/70 Heading H4R [Also in Division G1] In a system for measuring the difference between two signals 4, 6, in which a cyclic signal 7 is derived from the two signals, amplified (30) and then detected (20), a second, reference, cyclic signal 33, phase displaced by 90 degrees from the first, is passed through the same amplifier and detected separately (24) to provide a control signal, representative of the amplifier gain, which can be used to maintain the overall gain constant. The apparatus shown measures a noise signal 4 received at an aerial 2 by comparing it with a reference noise signal 6 to make the measurement independent of amplifier noise. A cyclically-driven switch 3 selects the two noise signals 4, 6, alternately to provide a first cyclic signal 7. A second switch 11, driven 90 degrees out of phase with the first, selects two reference noise signals 31, 32 alternately to provide a second cyclic signal 33. The two cyclic signals are combined (10) and passed via a mixer 15 to an i.f. amplifier 30, envelope detector 17 and a further, narrow-band amplifier 18 centred on the frequency of switches 3, 11. One phase-sensitive detector 20 detects the magnitude of the component corresponding to the first cyclic signal in the output of amplifier 18 to provide, after further amplification (22), an indication on a centre-zero meter 23 of the difference between the input noise signal 4 and the reference 6. A second phase-sensitive detector 24 detects the second cyclic signal component to provide a gain control signal 27 for amplifier 18 and, possibly, for amplifier 22 or 30 as well. The sources 5, 13 of the reference noise signals may be wave guide loads, gas tubes or semiconductor sources. The switches 3, 11, which may operate at 100 Hz, may be latching ferrite switches or rotary waveguide choppers.

Title: Navigation aid
IPC: G01S15/87
Filed: 1978-08-31
Abstract: A navigation aid for determining berthing data comprises distance detecting units embodying sonar transducers (T1, T2, T3) which are spaced apart along the length of a jetty a short distance behind the berthing line. The units (T1, T2, T3) are operative to provide signals indicative of the distance from the berthing line of correspondingly spaced sections of the ship, and a microcomputer (10) selects the more reliable two out of three of these signals and processes them to determine the extrapolated distance from the berthing line of nominal bow and stern sections of the ship, the bow-stern separation being greater than that of the actual measuring points at which the transducers (T1, T2, T3) are positioned. The microcomputer (10) also processes the selected signals to determine the velocity of the bow and stern sections relative to the berthing line, and controls a jetty display (12) of the determined distance and velocity data in addition to local and remote indications/recordal thereof. <IMAGE>

Title: Web Dispenser
IPC: B65H41/00
Filed: 1978-10-05
Abstract: A dispenser for wound rolls of flexible sheet material, such as, paper towels, toilet tissue or the like has inwardly facing tracks on the opposite inner side walls of the dispenser housing to receive therein outwardly projecting spindles carried by wound rolls to be dispensed for the rolls to move in succession downwardly relative to the tracks with a section of the lower end of each track slanting away from a feed roller mounted adjacent the lower end of the dispenser housing and each track having at such lower end section a pivotally mounted roll rotation driving guide biased toward the track center to form the lower side of each track section slanting away from the feed roller. A pressure roller is biased into rotating engagement with the feed roller for flexible sheet material to drivingly pass therebetween with the pressure roller having at least one resiliently deformable segment that is eccentric to the pressure roller axis to pick up the leading free end of sheet material on a full roll and lead it into the nip between the feed roller and pressure roller, this pressure roller also has axially spaced conical resilient portions along the length thereof with the conical portions facing from the opposite ends of the pressure roll inwardly toward the mid-point of the pressure roll to promote spreading out the sheet material passing between the feed roller and the pressure roller. A serrated cutting knife is pivotally mounted within the feed roller to sever the sheet material, the serrations on the knife being spaced to accommodate therebetween the deformable eccentric segment and the conical portions on the pressure roller during initial projection of the knife from within the feed roller in severing the sheet material. The cutting knife swings about an axis laterally displaced from the plane of a radially outward portion of the knife and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife edge engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.

IPC: H01L27/146
Filed: 1978-10-25
Abstract: Apparatus for parallel-in to serial-out conversion comprises a strip of semiconductor material (7) having electrical contacts (11, 13) at either end, and a detector (41) near one end, sensitive to the local density of ambipolar carriers. Ambipolar carriers (i.e. minority carriers embedded within and screened by a cloud of majority carriers) are injected into the strip at a number of parallel inputs (D1, D2, ...

The ambipolar carriers are swept to the detector (41) when a pulse of current of suitable amplitude and duration is applied to the contacts (11, 13). The parallel inputs may be in the form of diode diffusions to which electrical signals may be applied. Alternatively the inputs may be, as shown, lateral extended portions (OD1', OD2',... ODn') of the strip (7) in which ambipolar carriers are generated in response to incident infra-red radiation to provide an imaging array. <IMAGE>
