Abstract: 1,124,049. Ultrasonic measuring system. ATLAS-WERKE A.G. 24 Nov., 1965, No. 49946/65. Heading H4D. In an ultrasonic Doppler log device for measuring the speed of or distance travelled by a ship, variations in the propagation relocity of acoustic waves in water (due to variations of the water temperature or salinity) are compensated by controlling the acoustic transmission frequency in accordance with a value determined from the frequency of an acoustic standing wave established in a control path by means of a feedback system. In the embodiment of Fig. 1, a standing wave is established in a control path d by a feedback system comprising transmitting transducer S, receiving transducer E, amplifiers V and R, band pass filter BP, and a transformer TR. A signal whose frequency is that of the standing wave is available at a secondary winding of transformer TR and it, or an harmonic or subharmonic, provides the controlled transmission frequency of the Doppler device. The control path may be established by transducers mounted on the ship or on a submerged trawl device. In an alternative embodiment (Fig. 2, not shown) the standing wave is established between a single transmitting/receiving transducer (T) and a reflector (X). Transducer (T) is of the magnetostrictive type, having energizing and feedback windings coupled to a transistor oscillator circuit.

Title: Foregin particle inspection machine
IPC: G01N33/00
Filed: 1970-10-23
Abstract: 1330856 Ampoule inspection machine EMHART CORP 23 Oct 1970 [24 Oct 1969] 50449/70 Heading G1A A machine for detecting foreign particles in transparent liquid filled containers and employing the video detection apparatus of Specification 1269515, wherein an intermittently rotating turret with a plurality of angularly spaced chucks, for releasably retaining the containers, is adapted to take each container through a plurality of stations during which the container is rotated through one or more stations and then held stationary at an inspection station while the liquid inside is still swirling around, so that the liquid can be investigated by a video detection apparatus (such as above) to determine whether the container is to be dropped down a reject chute or a discharge chute. In an embodiment, Fig.1, a plurality of ampoules 36 are stored on a rotating table 34 above which a fence 52 and arcuate guide 54 are positioned so as to define a funnel shape into which the ampoules 36 are urged, the arrangement including a vibrator mounted on the fence to prevent toppling of the ampoules. A reciprocating slide block 60 with a "V" notch 62 takes each ampoule 36 in timed relation to an infeed station on a cam follower block 60, which is below one chuck 32, Fig.5, of a series of chucks attached to a turret 30 through spinning motors 84. At the in feed station each ampoule 36 is elevated by means of a rotary cam (64) Fig.3 (not shown) engaging the cam follower block 66 so that the ampoule is releasably retained in the chuck 32, Fig.5. The spinning motors 84 are connected by conductors passing to the base of the intermittently rotating turret 30 Fig.4 (not shown) to a variable D.C. supply by means of a slip ring and brush, and a commutator and brush. Each commutator segment is connected to a different set of variable resistors or limit switches to effect appropriate movement of each chuck at each stage. As explained above this involves spinning the ampoule 36 then holding it stationary in front of a detector such as a T.V. camera connected to logic circuitry Figs.7 and 8 (not shown). The logic circuit is such that if no foreign particles are detected than a signal is produced which causes the release of the ampoule from the associated chuck means by a bellcrank and push rod 108, which has a birfurcated member 112 mounted at its upper end so as to engage an annular collar 99 on the chuck 32 and activate a plunger 90 which pushes the ampoule from the chuck so that it falls down discharge chute 42. If no signal is received from the logic circuit the ampoule is automatically released at the next station by a further set of a bellcrank 100 and a push rod 110 etc., so that the ampoule falls down a reject chute 44. Suitable electric circuits for operating the spin motors 84 and details of the detector circuits are disclosed. (For Figures see next page)

Abstract: 1,193,317. Packaging cigarettes. ARENCO A.B. 7 Nov., 1967 [10 Nov., 1966], No. 50477/67. Heading B8C. A container device into which a quantity of cigarettes are dispensed from a store and in which the cigarettes are collected and retained so that during transport and insertion into a packet they adopt the positions they occupy in the finished packet, includes two plates arranged parallel to one another, plate 1 comprising a bottom plate and plate 12 a cover, and walls arranged between the plates in the longitudinal direction of the cigarettes and is characterized in that the walls are in the form of jaws 2 presenting opposing abutment surfaces and movably arranged on shafts 5 mounted in grooves 6 and 18 disposed in the bottom plate 1 and the the cover 12 respectively, the shafts 5 being adapted to be moved in a transverse direction by means of a lever 7 mounted on the bottom plate 1 and links 10, 11 between the lever 7 and the shafts 5. The lever 7 is actuated by a roller 9 at one end contacting an abutment as the device moves towards a cigarette storing position so that the jaws are moved apart. The rear ends of the jaws come into abutment with studs 13 and cause the jaws to pivot on shafts 5 so that the front portions of the jaws move further apart to further facilitate the insertion of cigarettes. Movement of the jaws also causes, through cam surfaces 19, 20, the cover-plate 12 to be tilted upwards at its front end to allow the insertion of the cigarettes. The leading edges of the jaws and the bottom and cover plates may be chamfered to further assist the insertion of cigarettes. The cigarettes may be arranged in rows and the number of cigarettes in one row may deviate from the number in remaining rows and to allow for this the abutment surfaces of jaws 2 may be formed with a bulge 4. After the cigarettes have been inserted into the device, actuation of roller 9 ceases and the jaws 2 and cover-plate 12 return to their original positions under the action of springs 21 and 15, respectively. The device with the cigarettes therein is then moved to a position where the cigarettes are inserted into a packet. The device is preferably mounted on a chain by means of studs 22 for movement to the various operating positions.

Alternatively a resilient packing may be interposed between the bearing plates and the stator. Preferably the self-lubricating sintered bearings used are self-aligning and are supported in part hemispherical supports. Axially projecting fan blades on the rotor are used to provide internal cooling.

Title: Speed measurement and indication apparatus

Filed: 1972-11-07
Abstract: 1415342 Digital speed measurement PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Nov 1972 [10 Nov 1971] 51306/72 Heading G4H In a digital speed measuring instrument, the indication is updated at a rate dependent on the rate of change of speed. As described, pulses of repetition frequency proportional to speed are fed via (2) to the three stages 3, 7 and 11 of a counter. Each stage has an associated store (4, 8, 12) decoder (5, 9, 13) and display (6, 10, 14). After a predetermined period of time (measuring period) the count is transferred to the stores by a pulse at 15, the counters are cleared and the cycle restarted. Alternatively the counters may be cleared without transfer of the contents to store. As shown in Fig. 3, the measuring period is determined by oscillator RO. The output pulse is fed to delay D from which it resets the counters and also to switch SEL which either switches it to Y to enter the reading into store for each pulse or to X and a pulse divider so that only some of the pulses enable the store. Switch SEL is operated by device CM which is activated when the rate of change of input frequency is greater than a predetermined value. This device may comprise (Fig. 15, not shown) a frequency to voltage converter (301) and a differential amplifier (310) whose inputs are derived both directly and via a sample and hold circuit (302) from the converter (301). As shown in Fig. 2, the voltage at the output of CM controls a variable frequency oscillator VPG and the store is enabled only when there is coincidence in CC between pulses from oscillators VPG and RO. In alternative embodiments (not shown) the first incoming pulse of a measuring cycle sets a bi-stable circuit which enables a gate allowing pulses to reach the counter and also synchronizes the operation of the oscillators and delay lines.
