Title: Clock mechanism
IPC: G04C1/08
Filed: 1973-03-19
Abstract: 1425893 Electric clocks KIENINGER & OBERGFELL 19 March 1973 [17 March 1972] 13144/73 Heading G3T [Also in Divisions F2 and G4] In a clock mechanism having an electric motor (3), Figs. 1 and 2 (not shown) energized intermittently to wind a spring 13 which is in tension between an escapement train driving wheel 12 and a winding wheel 9, the motor being switched on to drive the wheel 9 through a certain angle when the relative angular positions of the wheels 9, 12 have changed by a corresponding amount, the motor is coupled to the wheel 9 via an indexing mechanism which transmits rotary motion from a driving wheel 101 to a driven wheel 102 during a part only of each revolution of the drive wheel. Overrun of the motor after opening of switch contacts 39, 40 therefore has no effect either on the position of the wheel 9 and the spring tension after winding, or on time indicators e.g. of digital type which are driven directly by the shaft 8 of the wheel 102, thus ensuring proper positioning of the indicators. The drive wheel 101 coupled to the motor has four indexing teeth 107 and a circular locking portion 104 which can engage tangentially with the sides of spaced teeth 108 of the wheel 102 during over-run. Teeth 109, 110 of the wheel 102 are axially shortened to clear the portion 104, and a further short tooth 111 on the wheel 101 aids the initial motion of the driven wheel. The overlap ratio between the wheels is greater than one, so that the effective ratio between the four indexing teeth 107 and the twenty teeth of the wheel 102 is 1:4. The switch contacts are operated by a first switching wheel 21 fast with the wheel 9 and a second switching wheel 22 which is loosely pivoted and coupled to the wheel 12 by means of an arm with portions 30, 32 extending through an arcuate slot 31 in the wheel 22. A further slot 28 in the wheel is engaged by a pin 27 fixed to the wheel 21. Figs. 4a, b show the positions immediately after a winding operation, the end 44 of spring contact arm 24 lying in a gap between teeth 50 of the wheel 21 while a tooth 51 of the wheel 22 holds up the end 43 of the other contact arm 23 to separate the contacts. As the wheel 12 and the arm 30, 32 move clockwise under the pull of the spring 13, the arm comes up against the end of the slot 31 and rotates the wheel 22 allowing the contact arm 23 to drop and the contacts to close. The motor is thus energized to drive, via the indexing mechanism, the digital time indicators and the wheels 9 and 21, tensioning the spring 13. As the wheel 21 advances, the pin 27 engages the edge of slot 28 and also displaces the wheel 22. As the contact arm 24 is raised by the next tooth 50 of the wheel 21, the contacts remain closed, but they are opened after the tooth clears the arm end, by the next tooth 51 of the wheel 22 engaging the arm 23.

Filed: 1969-03-14
Abstract: 1282051 Electro-medical apparatus J M M NEILSON 12 March 1970 [14 March 1969] 13659/69 Heading G1N E.C.G. signals are monitored by integrating successive segments of the QRS complex, determining the differences between the integrated valve of each successive segments of the complex and the integrated value of a corresponding segment of a normal QRS complex, and quantitatively summing the differences to provide an indication of a normal or foreign (abnormal) complex depending on whether the sum exceeds or is below pre-set thresholds. As shown, the E.C.G. signal is applied both to an operational section via a delay line, Fig.5 (not shown), and to a trigger section. In the trigger section, Figs. 6 and 7 (not shown), two sets of pulses are produced - master timing pulses having a fixed time relationship to the start of each QRS complex and master trigger pulses having a fixed time relationship to the middle of each QRS complex. These two sets of pulses are applied to a control section, Fig.8 (not shown), which provides control pulses for the operational section, Fig.9 (not shown). The first control pulses (integrate reference segment) is initiated, after an adjustible delay with respect to the master timing pulse, to cause the delayed E.C.G. signal to be integrated prior to the occurrence of a QRS complex, this providing a reference level. Successive integrate segment pulses are then initiated and these cause each segment of the incoming QRS complex to be integrated and compared with the integrate of valve of the corresponding segment of a normal complex which are stored in the operational section. A sum of the differences, upon initiation of a "decide" pulse, is compared with pre-set thresholds. If the total exceeds a threshold, a foreign complex is present. However, if a normal complex is present, a logic circuit, Fig.11 (not shown), provides a transfer pulse to up-date the stores in the operational section with the integrated values of the segments just processed. The master timing and trigger pulses are also applied to a timing section which gives an indication of early QRS complexes. The logic section can then provide indications of the different types of complexes as shown in Fig.4. Utilizing the shown indications various heart malfunctions may be indicated, e.g. ventricular ectopic complexes, ventricular fibrillation (extreme irregularity of shape of the complexes), ventricular tachycardia (sequence of early foreign complexes), atrial tachycardia (rate of normal complexes above certain level), atrial fibrillation. An inhibit section, Fig.10 (not shown), if provided to inhibit operation when excessive background interference is present.

Filed: 1958-05-02
Abstract: 879,429. Indicating liquid levels. SMITH & SONS (ENGLAND) Ltd., S. April 28, 1959 [May 2, 1958; Aug. 7, 1958], Nos. 14133/58 and 25421/58. Class 123(1) A liquid level indicator particularly for a closed fuel tank consists of a housing 11 secured to the top wall 10 of the tank and containing a variable resistance over which slides a contact arm secured to a spindle 14 which extends through the casing. A float arm 15 is secured to the projecting part of the spindle and has a part 19 bent at right-angles thereto in the plane of movement of the arm, a cylindrical float 20 being soldered to the part 19. Stop lugs 17, 18 on the housing prevent the float from contacting the bottom and top of the tank. With this arrangement when the float is at its lowest position the liquid required to maintain the float floating is reduced to a minimum since most of the weight of the float and arm is taken by the spindle 14 whereas as the float rises it sinks deeper into the liquid since it will be supporting an increasing amount of the weight of the system until at the top of the tank the float is almost submerged, thus giving a complete range of indication from "empty" to "full". A weight 25 is adjustable along the arm 15 to allow the depth of immersion of the float at the "full" position to be controlled.
