Title: Deposited actuator perforated media reader
IPC: G06K7/04
Filed: 1969-01-09
Abstract: A perforated record 10, Fig. 3, is sensed by a plurality of actuators 42 carried by a carriage 25 which is driven across the record, an actuator 42, when sensing a perforation, being released from carriage 25 and being retained by the perforation, and the actuators having associated means for providing electrical signals representing their positions. Actuators 42 may operate a matrix of diaphragm switches, each row of which is associated with a different value resistor, and the columns of which are scanned by a rotary switch to produce voltages representing the positions of the sensed perforations in each column. The carriage 25 is driven across the record 10 by a forked member 23, Fig. 1, attached to the same shaft 21 as a handle 20. A pin 28 on handle 20 engages a slot in a cam 30 so as to wind a spring motor driving the rotary readout switch. The cam 30 is latched by an interposer 34 which is released by momentary energization of a solenoid 60 to initiate readout. If the data is correctly transmitted, solenoid 60 is momentarily energized a second time during the return movement of cam 30 so that interposer 34 clears an intermediate step on cam 30 which would otherwise arrest cam 30 and handle 20 in an intermediate position, thus indicating incorrect transmission.

Title: Composite heavy-duty mechanism element and method of making the same
IPC: F16C33/62
Filed: 1971-12-04
Abstract: A composite mechanism element, such as a bevel pinion (FIGS. 1 to 6 inclusive), or the inner race of a tapered roller bearing (FIGS. 7 to 10 inclusive and 16) has its working or load-bearing portion or portions composed of sintered powdered high-performance alloy while its supporting portion not subjected to concentrated or heavy loads, is made of a base metal, such as sintered powdered iron. The toothed outer load-bearing portion of the composite bevel pinion (FIG. 6) and the hollow frusto-conical inner supporting portion (FIGS. 10 to 15) are separately briquetted from high performance alloy powder and low performance metal powder respectively and separately sintered after which the low performance inner supporting portion is pressed into the high performance toothed outer portion so as to be inseparably secured thereto. In the inner race (FIG. 15) of the composite tapered roller bearing (FIG. 16) the low-performance and high-performance portions of the inner race are separately compacted in dies in a briquetting press to form briquettes which are separately sintered and thereafter are pressed together in an assembling operation which causes the high performance and low performance portions of each race to be inseparably secured to one another. The composite outer race is formed by arranging base metal powder and high performance alloy powder in abutting zones in an annular cavity of a briquetting press die and compressing them to form a composite briquette which is then sintered and afterward deformed in a forging die into its final annular shape. The resulting composite sintered powdered mechanism elements are of much lower material cost than corresponding mechanism elements formed of high performance alloy throughout yet perform satisfactorily and have sufficient strength and durability for most purposes. The tapered roller bearing races (FIG. 9) or the bevel pinion (FIG. 15) may be used as they are if of satisfactory density for their intended uses, or they may be further densified by being subjected to an additional hot forging operation with the article sintered thereafter if deemed necessary.

Title: Normally vented liquid-storage tank for ships, with closure device for automatically preventing leaking if the ship should sink
IPC: B63B25/08
Filed: 1974-01-04
Abstract: A shipboard storage tank for liquids, such as petroleum products or chemicals. To prevent pressure buildup, and to permit overflow during filling, a vent and overflow conduit is provided. In order to prevent this vent and overflow conduit from becoming a source of pollution if the ship should sink and also in order to prevent loss of the contents of the tank upon sinking, the invention provides an anti-pollution valve installed in the conduit, which automatically closes the conduit, should the ship sink. The anti-pollution valve is actuated to its closed position by the hydrostatic pressure as the ship sinks and it automatically equalizes the pressures between the sea and the liquid within the tank as the vessel sinks to deeper depths. Transient effects, such as surface waves, are prevented from actuating the valve. The anti-pollution valve also includes means that make it possible to dump the liquid out from the tanks of sunken ships and thereby salvage it.
