Abstract: A stack (S) of sheets is formed on a downwardly moving platform (4), the stack being divided into portions (P) each consisting of a predetermined number of sheets. As each alternate portion is completed, that portion is gripped between two plates (5, 20) and moved horizontally so that it is offset relative to the portion next below it. A completed stack containing the required number of portions is separated from the rest of the stack by inserting a divider (40) at the desired position. The platform (4) is then moved to remove those portions below the divider and, at the same time, an auxiliary support (41) moves beneath the divider (40) to support the stack above. The completed stack is removed from the platform (4) which is then raised level with the support (41). The divider (40), support (41) and platform (4) move together so that the stack is again supported on the platform (4).

Abstract: A process and apparatus for growing a layer of mercury cadmium telluride (HgCdTe) on a substrate is used in the fabrication of infrared detectors. The growth of a layer of HgCdTe by liquid phase epitaxy from a melt comprising mercury, cadmium, and tellurium requires a relatively high temperature which causes the mercury to constanily vaporize from the melt, thereby constantly changing the composition of the melt and the HgCdTe layer grown from the melt. This problem is overcome by providing a mercury-rich melt and also by condensing mercury vapors escaping from the melt and returning the mercury to the melt. First, a crystal growth melt (36) comprising mercury, cadmium and tellurium is provided in a vertically-oriented crystal growth chamber (14). The melt (36) comprises 33.33 mole percent or more of mercury and is maintained at a predetermined temperature above the liquidus temperature thereof. A condensing means (such as 15) is provided atop the crystal growth chamber (14) in order to condense vapors of mercury which escape from the melt (36) and to return this condensed mercury to the melt, to thereby maintain the melt at a constant composition. The substrate (not shown) in the substrate holder (22) is contacted with this crystal growth melt (36) for a predetermined period of time while cooling the melt below its liquidus temperature at a predetermined rate sufficient to cause the crystal growth of the layer of HgCdTe on the substrate to a desired thickness. The layer of HgCdTe so formed is of uniform composition and of high purity and is formed at a relatively low growth temperature and relatively low system pressure.

Abstract: 1. Time switch mechanism for the time-delayed triggering of a switching device, more especially for making explosive charges live, wherein the switching process is delayed by the constant rotation of an initially-tensioned toothed disc (13), which co-operates with a retard mechanism, through a predetermined angle of rotation at a predetermined angular velocity about a shaft (12) mounted in plates (10, 11) or in a plate (11) and is triggered once this angle of rotation has been traversed, wherein the toothed disc (13) has safety components associated therewith which block the toothed disc if the retard mechanism fails, characterized in that the safety elements contain a safety cam (16, 26) which is guided in guide grooves (20, 21, 27) in the plates (10, 11) or in a plate (11), said cam engaging in a carrier recess (17, 28) in the toothed disc (13) and being actuated by an external force in a substantially radial direction relative to the toothed disc (13), and in that the guide grooves (20, 21, 27) comprise a first portion, which extends substantially tangentially or in a circumferential direction relative to the toothed disc (13) over a predetermined angular portion (alpha, vtheta) of the predetermined angle of rotation (beta) and overlaps the carrier recess (17, 28) in the toothed cam, and a second portion which extends therefrom in a substantially radial direction, thereby resulting in the guide grooves (20, 21, 27) extending in a T-shaped or hook-like manner so that, during satisfactory operation, the safety cam is displaced into the radial portion of the guide grooves as a result of the external force after said cam has passed the first portion of the guide grooves (20, 21, 27) and thereby releases the toothed disc (13), whereas, in the event of a malfunction, the safety cam is securely clamped by the rapid full-rotation of the toothed disc (13) between the end of the first portion of the guide grooves and the carrier recess (17, 28) and blocks the toothed disc (13).

Abstract: A co-axial magnetron is provided with a cavity whose resonant frequency can be very rapidly altered in a cyclic manner so that the microwave output frequency of the magnetron can be chosen to lie within the available frequency band of the cavity. The cylindrical walls of the co-axial resonant cavity are constituted by or coupled to the inner surfaces of one or more tuning forks which are maintained in vibration by externally mounted electro-magnetic transducers. As the tines of the tuning forks vibrate, the effect is to cyclically increase and decrease the effective diameter of the cavity, thereby changing its resonant frequency. An adjustable end plate can be provided for the cavity so that fine tuning or slow rate tuning can be provided in addition to the frequency agility provided by the tuning fork.

Title: Method and installation for oil recovery by in situ combustion
IPC: E21B43/243
Filed: 1982-09-16
Granted: 1985-11-21
Abstract: Enhanced recovery of oil from subterranean sedimentary formations by an in-situ combustion method employing a pattern of an injection well and several production wells, spaced-apart by a treatment zone. Combustion is controlled by placing at least one fluid conduit in a treatment zone and introducing a control fluid through it to modify the flame front. Oxygen may be introduced to take over from combustion air initially introduced through the injection well, to sustain combustion and advance the flame front. Water may be injected through the injection well, alternating with the oxygen through the control conduit to continue a wet combustion method started with air. The strategic placing of control conduits and the introduction of appropriate fluids may be employed to improve the sweep geometry by advancing the flame front or retarding it, or invading areas behind it. Safety means is provided for introducing the oxygen at a velocity greater than the maximum flame velocity encountered in the flame front.

Abstract: This invention relates to the determination of parameters for selecting materials for use as liners in shaped charges to transfer the greatest amount of energy to the explosive jet. Multi-layer liners constructed of metal in shaped charges for oil well perforators or other applications are selected in accordance with the invention to maximize the penetrating effect of the explosive jet by reference to four parameters: (1) Adjusting the explosive charge to liner mass ratio to achieve a balance between the amount of explosive used in a shaped charge and the areal density of the liner material; (2) Adjusting the ductility of each layer of a multi-layer liner to enhance the formation of a longer energy jet; (3) Buffering the intermediate layers of a multi-layer liner by varying the properties of each layer, e.g., composition, thickness, ductility, acoustic impedance and areal density, to protect the final inside layer of high density material from shattering upon impact of the explosive force and, instead, flow smoothly into a jet; and (4) Adjusting the impedance of the layers in a liner to enhance the transmission and reduce the reflection of explosive energy across the interface between layers.

Abstract: In an apparatus for making plastics carrier bags from a web of tubular film of thermoplastic material, a feeding mechanism intermittently conveys the webs by one bag width and a severing mechanism cuts the web into half tubes along an undulating curve. A carriage displaceable in the machine frame transversely to the feeding direction of the web is reciprocated by a drive derived from a first rotating control cam through gearing. A cutting knife pivotable in the carriage about its longitudinal axis passes through the plane of the tube about an axis perpendicular thereto and is so controlled by an oscillating drive derived from a second rotating control cam that its edge is substantially tangential to the undulating curve at the cutting point. A detour assembly retards one of the half tubes to bring the bag side edge zones into phase and each half tube is formed into bags by a transverse sever-sealing device.
