Title: Electric time piece
IPC: G04C3/10
Filed: 1956-03-12
Abstract: 830,518. Tuning forks. BULOVA WATCH CO. Inc. March 12, 1956 [March 11, 1955], No. 7601/56. Class 88 (2). [Also in Group XVIII] In an electric timepiece having a tuning fork vibrator one or both tines of the fork has an abutment which limits the amplitude of oscillation of the tines. In the first example, Fig. 1, the abutment 7b is carried by a counterweight 7 on the tine 4, the electromagnetic impulsing means being carried by the other tine 3. The abutments 3a, 4a limit the outward movements of the tines 3, 4. The gear tain is driven by a pawl 20 carried by the tine 4. The abutment 7b or a second abutment could be carried by the cylindrical magnet of the impulsing means. Electromagnetic impulsing means may be associated with each tine and the tines may be inclined inwardly, Fig. 11. In another example, Fig. 13, the cylindrical magnets of the impulsing means have abutments 507b. Reference has been directed by the Comptroller to Specifications 746,465 and 761,609.

Abstract: 1341814 Measuring wear electrically COMPUTAS A S 18 Feb 1972 [22 Feb 1971] 7642/72 Heading G1N [Also in Division H1] A device for detection of wear on the surface 1 of a machine element comprises a detector element 3 having a coating of resistance material on a supporting plate 9 and electrodes 5, 6, which coating forms a resistance element of which a longitudinal side 7 is exposed at the surface 1 being subjected to wear so that the currentcarrying cross-section of the resistance element will be reduced along with the wearing-down of the surface so that the resistance value of the element is increased and may be measured. Wear of cylinder liners in piston machines and of liners in plain bearings may be monitored in this way. In a preferred embodiment the element is mounted in a conical plug 10, inserted in a correspondingly shaped bore in a machine element, and secured therein by wedges (13, 14) and insulating sheets (11) Fig.4 (not shown) the material of the plug and wedges having approximately the same wearing properties as the material of the machine element.

Title: Improvements in Electric Conversion.
Inventor: CABOT SEWALL
IPC: H02M1/22
Filed: 1916-06-01
Abstract: 106,008. Cabot, S. June 1, 1916. Commutator switching-arrangements; phase, changing; transformers.-In a system of conversion by polyphase commutation, the polyphase transformer employed has a very small leakage inductance so that the current may be commutated sparklessly with fixed brushes at all loads. An arrangement for converting from polyphase to direct current or vice versa is shown in Figs. 1, 2; one set of transformer windings 33, 34, 35, is connected to three-phase leads, and the other set is connected as a nine-phase winding to the commutator brushes 23 - - 31 supported on fixed bars 21. These brushes rest on the periphery of an insulating disk 16 in which are set four contacts 17 - - 20 each of which subtends an angle of twenty degrees. The contacts 17, 19 are connected to a ring 10, and contacts 18, 20 to a ring 11. The direct current leads are connected to brushes 14, 15 engaging the rings 10. 11. The disk 16 and rings 10, 11 are carried by a shaft rotated by a motor 1, which must be a synchronous motor when the apparatus is used to convert from polyphase to direct current. For converting from direct current to direct current at a different voltage, the windings 33, 34, 35 of the transformer are replaced by a nine-phase winding which is connected to direct current leads through a commutator and slip rings similar to the commutator and slip rings 16, 10. 11. The transformer has a small leakage inductance and is built with a maximum of iron and a minimum of copper, and in winding, the primary sections are sandwiched between the secondary sections. Each core carries the windings of one primary phase and one secondary phase with parts of other secondary phases. In a modification. Figs. 4 and 8, additional disks 42, 42<1> carrv contacts to cause the direct current circuit to be made and broken at a number of points simultaneously. Brushes 60 - - 67 are arranged in pairs over the contacts 51 - - 59, the two brushes of each pair being mounted side by side so that the circuit is comnleted through them as a contact passes under. The connexions also provide for commutating the currents in the transformer winding A B, B C &e. through condensers 76, 76<1>.

In order to detect fingerprints thereon substances are sprayed from a valve-controlled aerosol container with a pressurized solution of 0.1% ninhydrin, 94.7% isopropanol, 3% acetic acid, 2% water and 0.2% dipropylenglycol which has been mixed at - 40  C. with an equal amount by weight of a mixture of substantially equal parts of propane and butane. The proportions are by weight and instead of the propellent mixture of propane and butane, dichlorodifluoromethane may be used. Other solvents which do not react with the amino acid detecting reagent, i.e. the ninhydrin, may be employed, for instance, an organic solvent, such as a hydrocarbon, a halogenated hydrocarbon, and particularly a chlorinated hydrocarbon, or an ester, or the solvent may consist of a mixture of any of these. The solubility promoter, i.e. the dipropylenglycol in the above example, may be triethylenglycol. Inert gases such as nitrogen and carbon dioxide may be used as propellants. Specification 767,341 is referred to.
