Title: Inclined shelf vending machine
IPC: G07F11/32
Filed: 1971-11-04
Abstract: 1330194 Article dispensing machine VENDO Co 4 Nov 1971 [20 May 1971] 51267/71 Heading A4T [Also in Division G4] An article dispensing machine has longitudinally inclined article support means such as 36(Fig.9), and a gate 112 at the lower end which is effective to block articles 44 when operating member 108 is in a standby position (the circular part of the cam), and to pivot about 114 when the operating member moves to its operating position (by co-operation between spar 110 and member 130) to dispense an article. Cam surface 122 and pin 126 are so formed as to lock the gate in its blocking position until the operating member is operated, Rod 132 is effective to lift the first article 44 to start the dispensing movement, and then to block the second article 44' whilst gate 112 is still in the dispensing position. A plurality of such supports are arranged side-by-side, the operating means being arranged on a common shaft 88, each being regularly spaced about the axis of the shaft relative to the others. The shaft may end in a ratchet arrangement and an operating lever which is brought into the path of an actuator Fig.3 (not shown) by a solenoid arrangement actuated by selection of the article from a plurality displayed, each article being in one laterally arranged row of supports, the other articles being in similar supports above and/or below this. A device is also provided to indicate when a particular mechanism has no articles to dispense. Finger 164 (Fig.8) tests for the presence of an article only when the operating means is about to operate that particular mechanism. This is achieved by cam 150 also mounted on shaft 88. Absence of an article allows pivot of the feeler member 156, to move common member 168, which activates a common switch Fig.4 (not shown) to illuminate a "sold-out" sign.

Title: Improvements in or relating to Methods and Apparatus for Recording the Contour Lines of Topographic Surfaces.
Inventor: LAVERGNE MICHEL
IPC: G01S15/89

Abstract: 1,170,955. Echo-sounding. INSTITUT FRANCAIS DU PETROLE, DES CARURANTS ET LUBRIFIANTS. 18 Nov., 1966 [19 Nov., 1965], No. 51725/66. Heading H4D. In an echo-sounding system for the direct recording of contour lines, e.g. of the sea bed, transmitting devices or receiving devices are so spaced that wave interference occurs on transmission or reception, and the spacing and/or the wavelength to which the receiving devices respond is varied during the echo interval to satisfy the relationship where # is the wavelength, h is the spacing, #H is the required contour interval, and r is the slant range of a reflection point, M, producing the echo. In a first embodiment a strip of the sea bed at right-angles to the course of a ship is examined by a side-looking sonar having a transmitter which transmits an acoustic wavetrain at one second intervals. The echo from point M is arranged to be received in phase at a plurality of receivers R for all values of r by varying the receiver geometry during the echo interval. Thus, a number of receiver arrays of different geometry may be connected in turn to an echo-recorder during the echo interval. In a second embodiment the receiver geometry is constant but several ultrasonic frequencies are transmitted simultaneously as a wave-train and the receiving system is made responsive to each frequency in turn during the echo interval, thereby effectively varying # to maintain the required relationship. In a third embodiment both the receiver geometry and # are effectively varied. In a modification, receivers of fixed geometry and transmitters of variable geometry may be employed. When transmitters and receivers are mounted on a curved surface of the ship's hull, compensation for phase delays due to the curvature is provided. It is stated that the invention may also be applied to determining contours of the surface of the earth from an aircraft, using interference of radar beams, or contours of closer objects using laser beams.

Patent GB-525681-A (GB)
Abstract: 525,681. Time recorders. CHRONODIATIC (TIME CONTROL) Ltd., and EKIN, C. P. Jan 25, 1939, No. 2586. [Class 106 (iv)] In apparatus of the individual card type means are provided whereby different types of record, such as normal attendance and job time, may be made, said means comprising two or more card receivers any one or all of which may be moved laterally under the control of time operated or manipulatible means. In the embodiment shown in Fig. 1 two card receivers 3, 4 are provided one of which is stationary while the other is movable laterally to present a different column of an inserted card to printing and punching or cutting mechanism G. This mechanism also limits the vertical position of the card in its holder. To minimize the possibility of inserting cards in the wrong slot the slots may be of different width and the more frequently used slot more conveniently arranged. The width of the fixed slot may be adjusted to enable cards of different width to be used as by forming the card receiver into two parts connected by a screwed spindle. The time indicating mechanism, which is driven by a prime mover A, comprises a clock indicator B, minute and hour type wheels C, adjustable mechanism E for controlling the operation of a two colour ink ribbon D, and mechanism F for shifting one of the card receivers. The adjustable mechanism E, which is driven from the shaft 5 of the prime mover, operates a set of settable control discs 11, Fig. 2, and a cam 14. The cam co-operates with a ratchet mechanism 15, 21 to drive a screwed spindle 29 whereby the card holder 4a is moved laterally. This mechanism and the mechanism G which punches and limits the amount of insertion of the card is similar to that described in Specification 169,992, [Class 106 (iv)]. The screwed spindle 29 is provided with a spiral spring which returns the holder to normal position when the mutilated part of the gear 22 is opposite the pinion 28. A pivoted catch 36, Fig. 3, on the gear 22, aligned with the gap therein prevents tampering with the screwed spindle. The type wheels C are constituted by minute and hour wheels 43, 50, driven by gearing 40, 41 and by a transfer mechanism comprising a single toothed disc 44 and gearing 46, 47 and 48. The ink-ribbon mechanism D comprises a holder 51 and a guide frame (not shown) ; the holder may be driven by the shaft 5 or by the operating handle H and the guide frame may be controlled by the control discs 11. Access to the interior of the apparatus to tamper with the mechanism is prevented by means which closes the gap or slot along which the card holder moves. Various devices are described for this purpose comprising (1) collapsable springs at each side of the holder, (2) plate elements pivoted on either side of the gap and spring biassed to abut against each other and yieldable outwardly, or (3) curved plate elements pivoted to lugs on the card holder and shaped so as to overlap the gap in any desired position.

Abstract: 1,171,753. Digital transmission systems; frequency modulation; pulse modulation circuits; facsimile systems. XEROX CORP. 29 Nov., 1966 [17 Dec., 1965], No. 53503/66. Headings H3R, H4F, H4L and H4P. In a frequency shift system in which data is preceded by a synchronizing signal, e.g. as in a facsmile system, the sync. frequency signal is preceded by a pre-sync. signal which may be D.C. or a fixed frequency. The change from the D.C. pre-sync. signal to the sync. frequency occurs when the sync. frequency crosses the zero axis, and the change from the pre-sync. frequency to the sync. frequency occurs when both frequencies cross the zero axis in the same direction. In the embodiments described, the modulator is clamped by the pre-sync. signal and during this time a pre-sync. signal is passed to the system output. The sync. pulse either controls the modulator frequency or clamps the modulator and gates a sync. frequency to the output. A dividing chain provides sync. and pre-sync. pulses, and also the sync. and presync. frequencies so that the various waveforms are harmonically related. The modulator, Fig. 7 (not shown), may comprise a relaxation oscillator of which the charging capacitor (C.1) is shorted by the presync. pulse and is held at the level to which it would normally pass at discharge so that charging starts from this level when the pulse ends.

Filed: 1972-11-20
Abstract: 1363205 Vibrators CLARK EQUIPMENT CO 20 Nov 1972 [27 June 1972] 53556/72 Heading F2X  A vibrator comprises aeasing 2 in which rotate two pairs of eccentric elements 50, 52 and 50<SP>1</SP>, 52<SP>1</SP>, the casing being provided with clamping means 3 by means of which the vibrator can be suspended on a cross member, for instance of a vibratory compactor. Mounted on flanges on opposite ends of the casing 2 are hydraulic motors 54, 62. The motor 54 drives the eccentric element 52 which has a shaft 51 supported by the casing 2 on the side facing the motor 54, while the motor 62 drives the eccentric element 50 which is formed as a hollow shaft surrounding the eccentric element 52 and its shaft 51. The eccentric elements 501, 52<SP>1</SP> are fashioned and mounted as the eccentric elements 50, 52. Whereas the eccentric elements 50, 52 possess drives 62, 54, the power for the eccentric elements 50<SP>1</SP>, 52<SP>1</SP> is derived by gears 55, 57 from that of the eccentric elements 50, 52. The gears 55 are mounted on the shafts of the elements 50, 50<SP>1</SP>, the gears 57 on the ends of the shafts 51, 51<SP>1</SP> of the elements 52, 521 where the ends of these elements protrude out of the elements 50, 50<SP>1</SP>. The gears 55, 57 are equipped with the same number of teeth and mesh so that the eccentric elements 50, 52 and 50<SP>1</SP>, 521 are symmetrically arranged with regard to a plane passing midway between the two shafts. Thus while the element 50 for instance is directed with its eccentric weight downward, such will also be the case for the element 50<SP>1</SP>. Provided in the eccentric element 50 are stops 68, 69 against which a cam 67 connected with the eccentric element 52 can abut in two positions. In one position the centrifugal forces of the elements 50, 52 will add to one another while in the other position they will subtract from one another. The elements 50, 52 can be rotated with respect to one another by supplying a greater torque through the motor 54 than through the motor 62 or vice versa. In operation, the elements 50, 52 and 50<SP>1</SP>, 521 revolve at the same speed but in opposite directions as indicated by the arrows. Thus in operation the vibrator will have no overall horizontal component of force. The vertical vibration effect can be varied between a maximum value at which the centrifugal forces of the individual eccentric elements add to one another and a minimum value at which the pairs of eccentric elements each exert no effective vertically directed force.
