摘要:
An automatic locking window latch including a housing for holding a handle with a fully integrated bolt for securing a window, and a catch for engaging the window to release the bolt to secure the window, as well as to hold the bolt open to open the window. The catch may include a catch body, a spring guide, and a trigger pin. The spring guide slideably fits over a post attached to the housing for guiding the catch body and positioning a catch spring. In an unlocked position, an external force acting against the trigger pin causes the catch body to slide from between the bolt and a slide surface of the housing along the post. As the catch body moves past the bolt, bolt springs push bolt extensions of the bolt through the housing and into an adjoining window molding to secure the window. The catch spring presses the catch body against the bolt until the handle pulls the bolt from the locked position.

The present invention is directed to a cartridge comprising a rectangular base and four side walls which form a cavity into which an energy pack or a plurality of individual battery cells, either primary or secondary, are locatable. The cartridge is securable to an electrical apparatus by a latching mechanism. Alternatively, the cartridge can be integral therewith. In a first embodiment, a plurality of cells are locatable such that their positive and negative contacts are positioned against a set of positive and negative contact areas located along the first and second side walls. The first embodiment optionally comprises a contact arm, locatable substantially parallel to the second side wall, which includes a plurality of positive contact areas corresponding to and across from the negative contact areas located on the second side wall. A plurality of cells, having a shorter length than the battery cells locatable between the first and second side walls, are locatable between the contact arm and the second side wall. In a second embodiment, the cartridge includes first and second contact arms positionable substantially parallel to the third and fourth side walls, between the first and the second side walls. The plurality of battery cells are locatable between the third side wall and the first contact arm, between the first and the second contact arm, and between the second contact arm and the fourth side wall. The cartridge also provides circuitry to recharge the energy pack and/or secondary cells located therein.

A method of ironmaking by means of a smelting shaft furnace including the steps of supplying iron ore and coke to the top of the furnace; and injecting coal and oxygen into the smelting zone of the furnace to promote combustion, to control reaction temperature and provide heat for smelting, the quantities of coal and oxygen injection being within the range of 0.7 to 1.7 of stoichiometric conditions with respect to combustion to carbon monoxide and hydrogen.
摘要:
A method of removing heat from molten metal in which the metal is caused to flow freely within a gaseous media or vacuum over a body disposed within the metal stream such that any tendency for the metal to solidify during its passage is effective on the surface of said body against which the solidifying metal contracts into intimate contact therewith. The body may be forcibly cooled, e.g. by water. Accordingly, since the liquid metal is not enveloped by a channel or pipe, the solidifying shell tends to shrink on to the body, no gap is created, and this much higher heat transfer coefficients between the shell, the liquid metal, and the cooling body are achieved.

An equipment testing device facilitates the testing of telephone communications systems having a number of predetermined test terminals. The equipment testing device includes a housing with a plurality of electrodes mounted on the housing. Means are provided for connecting the electrodes to the predetermined test terminals and for correlating the electrodes and the test terminals so that a selected electrode is an extension of a selected test terminal.

A cold drawn free-machining steel bar having a composition consisting essentially of, in weight percent, C up to 0.15; Mn 0.7 to 1.3; P 0.03 to 0.09; S 0.30 to 0.50; Bi 0.05 to 0.25; the sum of Ni, Cr, Mo and Cu up to 0.15 and the balance iron. The ratio % Mn / %S is from 1.7 to 3.0 and the %Mn-1.62.times.%S is from 0.05 to 0.40. The ratio %Bi /(%Ni+%Cu) is at least 2.0. The yield strength of the steel bar is further determined by the draft in cold drawing the bar from the hot rolled state and the cross section of the bar prior to draft.

摘要:
A demand feed and moistening apparatus is adapted to advance successive gummed labels from a stack to a ready position at a label dispensing station from which each label may be readily manually withdrawn and thereby moistened. Thereafter the next label in said stack is automatically advanced to said ready position and remains in this position until it also is manually removed. The use of such a label dispensing and moistening arrangement greatly facilitates the manual grasping of successive moistened labels and the application thereof to items that are to labeled.

Embodiments of methods are disclosed for characterizing a tested polycrystalline diamond (“PCD”) element, such as a PDC cutting element. In an embodiment, a method for characterizing a tested PCD element is disclosed. An initial volume of a PCD element is measured using a coordinate measuring machine (“CMM”). A workpiece is cut with the PCD element so that the PCD element develops a wear flat. A post-cut volume of the PCD element is measured after cutting the workpiece using the CMM. A wear volume of the PCD element is determined at least partially based on the post-cut volume and the initial volume of the PCD element.

A resulfurized and rephosphorized free-machining steel bar formed by cold drawing a hot rolled steel bar has the composition, by weight, C up to 0.08%; Mn 0.6% to 1.4%; Si up to 0.1%; P at least 0.03%; S 0.25% to 0/50%; Cb 0.02% to 0.10%; the sum of Ni, Cr, Mo and Cu up to 0.15%; balance iron. The ratio of %Mn/%S is from 1.6 to 4.0, and the ratio of [%Mn-(1.62.times.%S)]/%Cb is from 2 to 50. The yield strength of the steel bar is further determined by the draft in cold drawing the bar from the hot rolled state and the size and cross section of the bar after draft. The relationship between strength and ductility is further improved by heavy drafting in cold drawing the bar from the hot rolled state.
摘要:
A parallel redundant actuator system of the kind wherein the signal in each of a plurality of lanes (31A, 31B, 31C) comprises the difference between a demand signal and a signal indicating the position of an output member of the system and the output member (3) takes up a position determined by the output of a summing arrangement (21) for the outputs of the lanes and wherein between the input of each lane and the output of the summing arrangement each lane has a non-linear input/output characteristic whose slope over a range of values of input in which changes of input due to failure of another lane occur is greater than if the characteristic were linear over the range of values of input over which the lane is capable of operation. The arrangement is intended to reduce the change in position of the output member which occurs on failure of a lane.
