Title: Improvements in electric clocks
IPC: G04C3/027
Filed: 1922-06-01
Abstract: 206,186. Prince, C. E. June 1, 1922. Electric clocks.-In an electric clock the pendulum &c. is free mechanically and its accuracy unaffected by irregularities in the time-indicating mechanism. The pendulum closes the circuit operating the clock 16 once in each swing by adjustable contacts 3, 3<1> and 4, 4<1>. A circuit reverser 9 breaks the circuit automatically and reverses the contacts 7, 7<1>, and 8, 8<1> before separation of the contacts 3, 3<1>, or 4, 4<1>. The pendulum &c. receives a suitable impulse from a coil or coils 17 and core 17<1>. The time-indicating mechanism may be stopped by a shunt circuit having a switch 33 and it may be accelerated by short circuiting the contacts 3, 4, and pendulum suspension thus causing the reverser 9 to work rapidly. The fixed contacts 3<1>, 4<1> may be replaced by flexible wires exposed through the cutaway parts of tubes which are rotatable on splitbosses for adjustment. In a modification the pendulum makes contact once in each vibration by operating a spring-controlled contact arm 43, Fig. 6, which closes the circuit through the clock 16 and armature 17. The circuit-reverser may have a single oscillating contact operating between two fixed contacts. The permanent magnet of the reverser may oscillate and the electromagnet may be fixed. Instead of the clock 16 a relay may be operated by the circuit for one or more distant secondary clocks. A slow-releasing relay may be actuated say once a minute by the clock 16 to operate one or more subsidiary clocks and a similar device may be used to give less frequent impulses to the pendulum.

Patent GB-200497-A (GB)
IPC: H01B11/14
Filed: 1923-06-19
Abstract: 200,497. Felten & Guilleaume Carlswerk Akt.-Ges. July 7, 1922, [Convention date]. Drawings to Specification. Annealing.-In a process for producing equal values of self-inductance per unit of length of lengths of conductors, which, for the purpose of increasing their self-inductance, are wound round in close spirals with one or more layers of thin wire of magnetizable material such as iron. the differences of permeability obtained in each length by the annealing of the conductors compensate the differences in the weight of iron by their action on the value of the self-inductance. The changes in the self-inductance are followed up by measurements during the annealing so as to regulate the annealing required to obtain the desired values of permeability and the annealing is effected by passing a current through the loaded conductor, the annealing being regulated by the strength and duration of the current. The conductor is wound spirally in a groove provided in a drum of fire-resisting material and for the 'purpose of facilitating the simultaneous annealing and measuring, the self-inductance is determined by measuring the output of the annealing current and its strength and voltage or by alternately connecting the conductor by an automatic switching device, at regular and very short intervals to the source of the annealing current and to a measuring device such as a Wheatstone alternating current bridge. The drum carrying the conductor is enclosed in a receptacle which is either evacuated or filled with a neutral gas. The Specification as open to inspection under Sect. 91 (3) (a) also states that the conductor is heated on the outside preferably by a blow-pipe flame, so that only a comparatively short portion of the conductor is brought to the annealing temperature, the heating device moving relatively to the conductor, and the annealing is interrupted and the self-inductance simultaneously measured at the moment when the desired value of the self-inductance is obtained. Before annealing, the conductor is wound on a drum in welldefined spirals which do not touch each other and is led over the annealing point in a regular manner and wound round a second drum. The terminals on the ends of the length of conductor being treated are connected through sliding contacts, at one end of each drum to a measuring device. During the rotation of the first drum the source of heat is moved along the longitudinal axis of the drum so that the annealing point moves along the whole length of the conductor wound on the drum. This subject-matter does not appear in the Specification as accepted.

Title: Palm print identification
IPC: G06V40/13
Filed: 1977-04-19
Abstract: 1535467 Palm print identifier INTERNATIONAL BUSINESS MACHINES CORP 19 April 1977 [21 May 1976] 16261/77 Heading G4R Palm print identifying device has a scanning probe carrying a transducer and arranged so that relative movement occurs between the probe and a palm to be identified by the device. The probe and transducer generate signals indicating the spacing of major palm lines during the relative movement. In one embodiment (Fig. 3) the palm is placed on a flexible sheet 54 on a plate 20 carrying several probes. The palm is located by a peg 25. Mounted to rotate about the peg under control of a motor 27 is a bar 26 carrying the probes. The probes may be rods which slide against sheet 22 or may be transparent rollers 30-33 rotatable about respective shafts. Each roller has an associated light source and detector. The source illuminates the inner surface of its respective roller at the point where it contacts the palm. When the roller passes over a palm line the air gap above the roller causes the roller to reflect the light to the detector. If a palm line is not present the light is scattered. The rollers may contact the skin directly. A rod may be used instead of several rollers. The sheet may be replaced by an endless web passing over two spaced rollers (Fig. 7, not shown). The support 46-49 for each roller carries markings which are read to determine the height of each roller as it passes over the palm. A sensor 41 reads markings indicating the position of bar 26 to determine the location of the palm lines. The locations of palm lines detected by selected rollers and the contour of the palm detected by selected rollers is compared with stored data (Fig. 11, not shown) to determine validity of the palm pattern.
