Filed: 1938-08-05
Abstract: 499,739. Sewing machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.) Aug. 5, 1938, No. 23160. [Class 112] An imitation moccasin seam is produced in a sewing-machine by forming a ridge or bead in the material, maintaining it by a seam, and scoring the upper side of the ridge. In the machine shown, the work is fed by a dog 16 and feed-foot 17, and the ridge is formed by a finger 37 on the throatplate in co-operation with a #-shaped presser-foot 18 ; the ridge is secured by a seam formed by a pair of needles 10 operating on opposite sides of the ridge and co-operating with a single rotary shuttle 11, and is scored by a knife 38 carried by a bar 42. The throat-plate has a transverse slot to receive the needles, and the presser-foot 18 has needle-holes in its upper part merging into grooves on the inner sides of its limbs ; the feed-foot 17 is forked to engage the work at the sides of the presser-foot 18. The presserbar 27 and the feed-bar 20 are actuated bv a return crank 29 on the needledriving crank-disc 7 through a link 28 and a lever 23 which is pivoted to the feed-bar and to a lug 25 on the presser-bar ; the presser-foot and feedfoot are thus raised alternately in the known manner. The return motion of the feed-foot is produced by a spring 30 when the foot is raised, this motion being limited by a bracket 31 on the presser-bar. The knife-bar 42 is guided in the machine frame and by a bracket 43 on the presser-bar, and is pressed downwards by a spring 46 so that the knife 38 constantly engages the work through a slot in the top of the presserfoot 18 ; the depth of the score made by the knife is determined by a stopcollar 45 on the knife-bar. The presserlifting lever 54, acting on a lug 53 on the presser-bar, engages a lug 52 on a member 49, carried by a collar slidable on the presserbar, which lifts the knife-bar 42 by means of a lug 48 and releases the thread tension by means shown in Fig. 1.

Title: Improvements in or relating to electrical flash lamp sychronising devices for use with photographic camera shutters
IPC: G03B15/04
Filed: 1953-08-31
Abstract: 729,710. Photographic flashlamp synchronizers. KODAK, Ltd. Aug. 31, 1953 [Sept. 5, 1952], No. 24013/53. Class 98 (1). [Also in Group XXXVII] A flashlamp synchronizer for use with a solenoid-operated photographic shutter and adapted to synchronize flashlamps of two different lag classes comprises a power-driven contact for connection to one side of the shutter-operating solenoid circuit and to one side of the lamp circuit, a pair of lamp contacts for connection to the other side of the lamp circuit, one being fixed near the end of the path of movement of the movable contact and the other being removably located near the start of said path, the distance between the two lamp contacts being such that the time required by the movable contact to cover it is equal to the difference in lag between the two classes of lamp, and an adjustable solenoid contact in said path between the lamp contacts for connection to the other side of the solenoid circuit. As shown, the synchronizer comprises a movable contact strip 17 secured to a rotatable insulated gear segment 37 mounted in an insulated housing 13 and meshing with an inertia wheel governor 70, the segment being driven by a spring 39 tensioned by leftward movement against a return spring 48 of a slidable trigger 47. When the spring 39 is tensioned, an edge- 68 on the trigger trips a three-armed latch lever pivoted at 56 allowing the gear segment to rotate clockwise. As a result, a V-shaped contact 19 moves in succession over a contact 28, a contact lug 23 on a stiffly mounted disc 22 and a fixed contact 26. Contacts 26, 28 are connected in parallel to one side of a flashlamp socket, contact lug 23 is connected to one side of a solenoid shutter-operating circuit, and the movable contact 17 is connected to the other sides of these circuits. The distance between the contacts 26, 28 is adjusted to the rate of movement of the contact 17 so that the interval between their engagement thereby is equal to the difference in lag for class F and M lamps. If a class M (long lag) lamp is used the contact 28 is in the position shown while if a class F lamp is used the contact 28 is swung clockwise out of the path of the contact 17 by means of an arm 30. The lag between solenoid energization and shutter opening is intermediate to the lags of class F and M lamps and the appropriate contact position for each solenoidshutter combination must be found empirically, the disc 22 being adjustable by inserting a pin in the hole 36 in the arm 35. Both the shutteroperating solenoid and the lamp are operated by condenser discharge, a single battery carried in the flashlamp holder supplying both circuits.

Abstract: 1,227,903. Acceleration sensing device. GRAVIMETRICS Inc. 12 May, 1969, No. 24048/69. Heading H4D. An accelerometer comprises an electromagnet 48, Fig. 1, having its excitation current servo-controlled to keep a suspended magnetic sphere 8 (80 in Fig. 2a) centrally located with respect to four points 34A, 34B, 36A, 36B irrespective of accelerative forces on the sphere, the four points being defined by four corresponding light detectors receiving the light passing around the sphere from source 14, and the restoring (servo) component of the electromagnet current, as derived from the detector outputs giving the acceleration force on the sphere in magnitude and direction. The output of lamp 14 is varied by means of oscillator 10 and pulsed by means of modulator/chopper 12. The light passing the sphere at the two vertically aligned points and the two horizontally aligned points is conveyed to the respective pairs of light detectors 34A/ 34B and 36A/36B, by means of respective light guides 20/22 and 26/28. The outputs of the detectors will be A.C. currents having respective amplitudes depending on the position of the sphere. Thus at equilibrium, Fig. 2a, all four detectors are equally illuminated giving equal amplitude outputs. An upwards accelerating force on the sphere will cause the output of detector 34B to rise above that from detector 34A. The outputs of detectors 34A and 34B are thus fed to a differential amplifier 40 to give two difference A.C. outputs (one the inverse of the other). These two outputs are detected in synchronous detector 42 with respect to the output of oscillator 10. Equal but opposite D.C. outputs are then produced, which outputs are subtracted in difference amplifier 44, to give a D.C. signal, indicating in sign and magnitude, the vertical component acceleration V on the sphere. A similar system of difference amplifiers and detector produces from the outputs of detectors 36A/36B a signal indicating in sign and magnitude the horizontal component acceleration H on the sphere. The vertical acceleration signal V is fed to the electromagnet energizing circuit 46 whereby the electromagnet field is varied to restore the sphere to its equilibrium position. The field of the electromagnet varies monotonically out from a vertical axis, whereby an acceleration force inducing horizontal movement of the sphere, will put said sphere in a region of different magnet force whereby a vertical change in its positions will be produced. This vertical change when corrected as above simultaneously corrects the horizontal deviation. Restoration servo use of the horizontal acceleration signal is thus not necessary. The vector of the acceleration may be indicated by an operational amplifier 56 deriving a signal representing H<SP>2</SP> + V<SP>2</SP>, and the angle of the vector is given by an operational amplifier 58 deriving a signal representing tan<SP>-1</SP> (V/H). A phase comparator 60 determines from the vector amplitude signal and the signals V and H, the quadrant in which the acceleration vector acts.
