Title: Automatic hand firearm
Inventor: TIMARI JALI
IPC: F41A3/66
Filed: 1982-10-27
Granted: 1988-02-11
Abstract: PCT No. PCT/FI82/00050 Sec. 371 Date Jun. 27, 1983 Sec. 102(e) Date Jun. 27, 1983 PCT Filed Oct. 27, 1982 PCT Pub. No. WO83/01679 PCT Pub. Date May 11, 1983.The invention concerns an automatic, mass-obturated hand firearm comprising a body (1) with handle (2), a barrel (3) joined to the body, a breech block (4) with guide (5) constituted by the body and with cocking and firing mechanism (7), the guide of the breech block ascending rearward so that the rearward path of motion of the breech block deviates upward from the center-line (8) of the barrel. The purpose is to eliminate the problem of automatic hand firearms that during shooting the barrel tends to rise upwards. As taught by the invention, when the breech block (4) is in its forward position its center of gravity (9) is located forward of the handle (2). The breech block (4) is preferably disposed to have its major part forward of the rear end (10) of the barrel (3). Furthermore, the center of gravity (9) of the breech block (4) is preferably located forward of the rear end (10) of the barrel (3). The guide (5) of the breech block (4) forms a preferably obliquely forward and downward inclined surface, against which the breech block rests so that when the rearward directed recoil force acts on the breech block this plug moves rearward and the surface of the breech block hits against the surface of the guide, producing on the body (1) a moment turning downward the muzzle of the barrel (3).

Title: Method and apparatus for determining the flow velocity of a molten, radiation-emitting material
Inventor: RANSHEIM ANDERS P
IPC: G01F1/56
Filed: 1983-05-24
Granted: 1986-10-02
Abstract: The invention is related to a method and an apparatus for measuring the flow velocity of a flow, stream or jet of molten radiation emitting material, in particular a freely falling jet of molten glass. The intensity of the radiation emitted from a limited section (2, 3) of the material flow is detected by means of two radiation detectors (S1, S2) at two separate locations mutually spaced apart by a given distance (L) along the flow path of the material flow. All pulse-like amplitude variations having an amplitude exceeding a given magnitude are discriminated from the output signals of the two radiation detectors. These pulse-like amplitude variations originate from randomly occurring, local, discrete, short variations in the intensity of the radiation emitted by the material flow caused by randomly occurring inhomogeneities in the material, for instance in the form of air bubbles in a jet of molten glass. The time interval between a pulse-like amplitude variation in the output signal from the up-stream detector (S1) caused by an inhomogeneity in the material flow (1) and the occurrence of a pulse-like amplitude variation in the output signal from the down-stream detector (S2) caused by the same inhomogeneity in the material flow, is measured and used as a measure of the time taken by the material flow to travel between the detector locations, for calculating the flow velocity of the material flow. Also the volumetric flow rate of the material flow can be determined by measuring also the diameter of the material flow with the aid of a linear array of photodiodes and calculating the volumetric flow rate on the basis of measured values of the flow velocity and the diameter.

Title: A rotary positive displacement machine
Inventor: TOWNER JOSEPH LEONARD
IPC: F01C1/08
Filed: 1983-07-27
Granted: 1988-05-19
Abstract: The high pressure port in a rotary, positive displacement machine, such as a gas compressor, has an extension which is traversed by the plane on which the parallel axes of the rotors are commonly positioned. A given portion of the port extension is constantly occluded by the gating rotor and, consequently does not add to the effective area of the port. The remaining portion of the extension is exposed by the gating rotor, defining a port opening which reaches to the common plane. Thus, in gas compressor use of the machine, the port extension ensures that all the compressed gas product is delivered through the exhaust port.

Title: Method and apparatus for restoring data in a computing system
Inventor: BAKER JERRY WAYNE
IPC: G06F11/14
Filed: 1983-05-06
Granted: 1989-11-02
Abstract: Method and apparatus for assuring atomicity of user requested multi-row update operations to tables such as in a relation database (24), guaranteeing that for any update operation that succeeds all stated effects will have occurred and that for any update operation that fails the system state as perceived by the user remains unchaged. This is accomplished by establishing, in response to a multi-row update operation request, an execution module containing machine language code instructions implementing the update operation request with a savepoint request at the beginning of the execution module. For each set of instruction in or called by the execution module which modified the user perceived system state, undo information is logged to a soft log (20). Upon completing the execution module, the savepoint is dropped, causing all soft log information recorded since the savepoint to be deleted and releasing all resources held to guarantee restoration of the user perceived system state at the time of the savepoint request. Responsive to the detection of an error during execution of the module, the soft logged undo information is used to restore the user perceived state to that existing at the time of the savepoint request.

Title: Radiation activated addition reaction
Inventor: DRAHNAK TIMOTHY J C O MINNESOT
IPC: C08L83/04
Filed: 1984-03-02
Granted: 1988-07-14
Abstract: This invention relates to a process for reacting a compound containing silicon-bonded hydrogen with a compound containing aliphatic unsaturation in the presence of actinic radiation and to compositions that contain an actinic radiation-sensitive catalyst that are useful in the process. Although many platinum complexes are useful as catalysts in processes for accelerating the thermallyactivated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for accelerating the ultraviolet radiation activated addition reaction between these compounds, using a platinum complex as a catalyst, are not known. The ultraviolet radiation activated addition radiation can be conducted in the presence of a platinum complex having an ultraviolet displaceable group, e.g. a ( -diolefin) (-aryl) platinum complex. This process is useful for the in situ curing of a polymeric silicone composition to a solid surface, particularly one which is heat-sensitive.

Abstract: Defects in an underground channel, such as a sewer, are detected by an infrared scanning device (preferably an infrared video camera) moved internally along the channel. The scanning device senses temperature deviations which mark defects in the channel, as, for example, deviations due to the inflow of cool extraneous water into a sewer. The scanning device is in communication with an above-ground central unit which processes the scanning device output and displays and/or records thermal representations of the defect. The central unit also monitors the location (distance travelled) of the scanning device so that the locations of defects may be determined.

Title: Method of simultaneously producing bipolar and complementary mos transistors as a common silicon substrate
Inventor: JACOBS ERWIN P DR
IPC: H01L21/8238
Filed: 1986-05-13
Granted: 1989-05-03
Abstract: A method for the simultaneous manufacture of bipolar and complementary MOS transistors on a common silicon substrate, wherein n-doped wells are produced in a p-doped substrate for accepting p-channel transistors and npn bipolar transistors are formed into the n-doped wells, the n-well forming the collector of the transistor and the n-wells overlying buried n+-doped zones which are connected in the bipolar transistor region by more deeply extending collector plugs. A buried part and plug region of the collector are produced before the production of the wells, and the collector region is formed in the substrate in common with the well so the high-temperature step after the conventional LOCOS process is eliminated. The well implantation is self-adjusting relative to the implantation of the deep collector plug which is annularly formed in the well. A reduction of the collector series resistance as well as an increased latch-up hardness is obtained. Further, the parasitic substrate-pnp is reduced. The method is particularly useful for the manufacture of VLSI circuits with high switching speeds.

Abstract: A projectile comprises a pyrotechnic charge and a mobile member inside the projectile which rotates between a safe position and an armed position. At least part of a pyrotechnic delay device is accommodated in a passage in this mobile member. The pyrotechnic charge is initiated via this pyrotechnic delay device. The passage is oriented so as to isolate functionally the pyrotechic delay device from the pyrotechnic charge when the mobile member is in the safe position. It functionally couples the pyrotechnic delay device to the pyrotechnic charge when the mobile member is in the armed position. The projectile further comprises an arrangement on the mobile member and on the projectile to guide relative rotation between them about an axis fixed relative to the mobile member and relative to the projectile. A mechanical arming device retains the mobile member in the safe position and against rotation about the aforementioned axis relative to the projectile at least until the projectile is fired. It obliges the mobile member to move to the armed position when the projectile is fired by rotating about the axis relative to the projectile.
