Filed: 1917-09-22
Abstract: 121,755. Hodges, R., and Hodges, J. M. Sept. 22, 1917. Kinematograph apparatus. - In a projector, a shutter S is held out of the light beam during projection by a detent T which is withdrawn to release the shutter, and permit it to cut off the light, when the film breaks or runs out or the speed of the mechanism falls; a switch in the circuit of the driving motor may be opened simultaneously. As shown, the shutter S is pivoted at Y on a condenser hood S1, the detent T engaging a slot in the end of the shutter arm SA. The detent is linked to a bell-crank lever L1 the other arm of which is connected through a pin L3 and a slotted link L2 to one arm of a lever L pivoted at P and carrying a roller R bearing on the film between the feed and take-up mechanism. Slackening of the tension in the film allows the lever L to fall and the detent to be withdrawn. A governor K driven by the mechanism carries a disk D on which is mounted a pin DP. When the speed of the mechanism falls below normal the disk D moves axially and brings the pin DP into a position such that it strikes a lever L8, which is pivoted at L4 and has a slot engaging the pin L3, and withdraws the detent T. A mercury or other switch M in the driving motor circuit may be connected to the link L2 or to the lever L1.

Title: Improvements in photoelectric relay
IPC: H01H47/24
Filed: 1938-05-09
Abstract: 514,528. Valve circuits. PHOTOSWITCH Inc. May 9, 1938, No. 13786. Convention date, Sept. 16, 1937. [Class 40 (v)] In a system in which a relay M is controlled in accordance with the illumination of a photoelectric cell P through valves T and U, empedances 1 and 107 are connected to the grid and cathode of the valve and are so adjusted that the control-electrode potential is lower or higher than the cathode potential as the impedance of the cell P is higher or lower respectively. The apparatus is connected to an alternating supply AB, and is arranged so that with the cell dark and the terminal A negative, the anode 31 is positive and the adjustment of slider 3 is such that the potential of cathode 4 is higher than that of grid 6, the potential of which is determined by impedance 1. Under these conditions no current flows through the valve. When terminal A becomes positive, anode 31 is negative and the valve is blocked. When the cell is illuminated, the impedance of cell P is reduced so that when plate 31 is positive the control grid 6 becomes more positive than cathode 4 and magnet M is energised. During the negative half-cycle the valve is again blocked, but sufficient energy is stored in impedance L to hold the magnet M engaged during the half-cycle, and the magnet remains energised so long as the cell is illuminated. The potential of screen 21 is adjusted to prevent the collection of positive ions on the control grid 6. The Specification as open to inspection under Sect. 91 also describes an embodiment in which the magnet is de-energised when the cell is illuminated. This subject-matter does not appear in the Specification as accepted.

Title: Preparing metal articles having a repeatedly reversible shape memory effect
IPC: C22F1/10
Filed: 1975-04-04
Abstract: 1499404 Working at specific temperatures UNIVERSITY OF OSAKA 4 April 1975 [4 May 1974] 13969/75 Heading B3V [Also in Division C7] Metal articles for switches or pressuresensitive elements with reversible memory shape are prepared from #-brass type martensitic alloy by applying at a temperature below the Md point a deforming stress in a range the lower limit A, Fig. 1, of which exceeds the first yield point of martensite crystals in the alloy and is beyond the easy plastic flow region, and the upper limit B is below the second yield point at which macroscopic strain is produced by glide deformation. Preferably the deforming stress is applied below the Ms or Mf points. Suitable alloys are Ni-Al, Ni-Al-Co, Ni-Al Ga, Ni-Al-Zn, Ni-Al- Ti, Ti-Ni, Ti-Co, Ti-Fe, Ni-Ti-V, Ti-Ni-Cr, Ni-Ti- Mn, Cu-Zn, Cu-Zn Ga, Cu-Zn-Al, Cu-Zn-Sb, Cu-Zn Sn, Cu-Al, Cu-Al-Ni, Cu-Al-Co and quaternary alloys including Ni, Pd, Ti and Zr. Preferably Ni-Al alloys have 55 65 at per cent Ni, balance Al. Suitable Ni-Al-Co alloys have a composition range as shown in Fig. 2. The deforming stress may be applied by bending, twisting, compressing, drawing or swaging. By heating the deformed article above the As or Af points it partially or completely turns to the undeformed shape. Subsequent cooling below the Ms or Mf points changes the alloy again into martensite phase and returns it at least partially to the deformed shape. In an example, an alloy of 63À2 at per cent Ni, remainder Al, with M s  point above 50‹ C. and Af point 70‹ C., was melted, cooled gradually and heat treated at about 1300‹ C. for three days to form a coarse grained alloy from which a single crystal alloy was obtained. A 0À3 mm. plate of the single crystal alloy was quenched from 1250‹ C. to obtain the martensite phase. The plate was then prestressed by cold rolling with a reduction of less than 5%, e.g. 3%, followed by bending to a radius of about 20 mm. Such curved plate was returned to its original form by heating and to curved form upon cooling, Fig. 3 (not shown). Instead of using the single crystal part, the coarse grained part of the metal may be used. Another example uses a Ni-Al-Co alloy having 63À8 at per cent Ni, 1À0 at per cent Co and the remainder Al.

Filed: 1928-05-15
Abstract: 302,882. Cutler-Hammer Manufacturing Co., (Assignees of Lockett, R. G.). Dec. 23, 1927, [Convention date]. Controlling extent of travel.-An electric motor 11, Fig. 1, driving a rotary washing machine 10 has control arrangements providing for three stages of action. In the first stage, after closing a switch 22, the motor is connected to the supply through a continually revolving drum controller D fitted with contacts and resistance which determine intermittent forward and backward running of the washing cylinder as long as may be desired. The line connections pass through switches 1<a>, 1<b> as shown diagrammatically in Fig. 2. For the second stage the operator closes momentarily a push-button switch 23, and thus initiates stoppage, which can only take place after the controller drum D has reached full speed position and the washing cylinder has reached a position determined by a cam 42. In this position the loading and unloading door of the machine is in register with one of the compartments of the washing cylinder. For the third stage the door of the machine is opened, which has the effect of cutting-out the drum controller through opening a switch 12, and a push-button 29 is depressed, which has the effect of restarting the motor for a short run terminated automatically by the arrival of the washing cylinder at another angular position corresponding to another compartment in register with the door. Successive depressions of the push-button 29 bring about successive angular movement of the washing cylinder determined by cams 45, 52 on the cylinder shaft, access being thus obtained in turn to all the compartments. During the third stage an automatic switch 34 moves against a biasing spring under a force due to magnetic drag of a rotating disc 37 on a magnet 36, for the purpose of putting the motor under the control of the switch 32, 33 operated by the cams 45, 52. After each automatic stop the switch returns to the position shown in the Figures, in order to ensure that a restarting circuit can be made through the push-button 29 while one of the switches 32, 33 is open.
