Abstract: The disclosure is directed to a semi-automatic mail insertion machine which assists an operator in placing materials into envelopes (26). The machine includes a horizontal conveyor (20, 21) which, under operator control, incrementally advances the envelopes (26) to be processed from one processing station to another in succession. An envelope stacker (25) is positioned above the conveyor (20, 21) and a feed means (55, 56) feeds the envelopes (26) to the conveyor (20, 21) prior to each advancement of the conveyor. The envelopes (26) are conveyed to a first process station (30) which automatically unfolds the pre-folded unsealed envelope flaps. The envelopes are then advanced to a second processing station (35) which opens the envelopes and presents the envelopes to the operator in a manner which permits ready placement of materials into the envelopes. A third processing station (45) may be provided which weighs the envelopes and the material therein to facilitate the sorting of the processed envelopes by weight.

Abstract: A water separator consisting of a baffle (12) and scupper (16) is inserted inside the outlet header (14) of a regenerative heat exchanger (10) for removing water from the air discharged therefrom. The cooled air which contains water droplets leaving the core (11) of the heat exchanger (10) is passed through a baffle (12) constructed to provide a gradual restriction in area in order to increase flow velocity. Heavy droplets of water are separated by the sudden change in airflow direction through the baffle (12) and header (14). The flow including the heavier centrifuged water droplets then impinge on the inside surface of the header (14) to which the accumulated particles of water adhere and are accelerated by the airflow and the contour of the header (14) toward a scupper (16) located downstream of the baffle opening 17. The water is collected in the scupper cavity 25. collected in a drain well, and drained with the assistance of gravity and the resulting pressure differential across the drain port. The scupper (16) contains holes (23) of louvered slots (28) whereby some air used to carry the water along the header inner surface may pass therethrough to combine with the remaining airflow in a duct (26) through which the dried air is removed from the system.

Abstract: 1. Device for a continuous generation of the requisite pressure forces in an infinitely variable gear, consisting of a driving disk (2) mounted on a driving shaft for positive rotation therewith, and of one or several driven disks (2a) extending parallel to the driving disk and also mounted to a shaft for positive rotation therewith, and of one or several rolling bodies (1) which are clamped between driving and driven disks, such that the power to be transmitted is transmitted due to friction between disks and rolling bodies, characterized in that the torsional moment corresponding to the respective power of the driving means generates via an intermediate element (5) a force, which is proportional to the torsional moment, which force acts via a lever arm means onto the pivotably arranged driving disk and therewhith onto the rolling body and the driven disk, which secures at any time a force-independant friction between the transmitting elements, and in that said lever arm means is chosen such that the load dependant force generates in cooperation with the lever arm defined by the distance between pivot centre (A) of the driving disk (2) and the point of contact of the rolling body, for the various drive speeds, that is within the range of displacement of the transmitting rolling body, the location dependent pressure corresponding to the location of the rolling body which is necessary for securing the friction.

Abstract: The precise positioning of a component such as an engine bedplate (5) in a ship under construction is predetermined by making height measurements on the bedplate at a number of support positions before the bedplate is installed. A sighting line (ABCDEF) is established relative to the tank top (4) of the ship under construction by an optical sighting method and an optical sweep is made in a plane parallel to this sighting line to measure the distances from the sighting line of each of the bedplate support positions on the tank top so as to predetermine the height of individual bearing elements for the engine bedplate. Similar techniques are employed to establish the fore-and-aft and athwartships positioning of the engine bedplate before its installation. The positioning of machinery in the ship can therefore be predetermined accurately without all the ancillary components having to be in place, and with minimal in situ adjustment.

Abstract: And earth leakage protection device comprises a core balance current sensing transformer (1) having a secondary winding (2) in which a fault signal is generated in response to leakage from AC supply lines forming primary windings of the transformer (1), an operational amplifier (OAI) for amplifying the fault signal, a precision rectifier circuit (8) comprising a pair of operational amplifiers (OA2 and OA3) for performing full wave rectification of the amplified fault signal, delay means (9) in the form of a two stage RC network which delays the rectified signal according to an IDMT characteristic, and a trigger circuit (10) in which the delayed signal is compard with a preset reference signal by an operational amplifier (OA4) to provide a control signal which actuates a safety device in the AC supply lines via a relay (11) when the reference signal is exceeded. Within its operating rangs the device actuates the safety device much more slowly for lower leakage currents than for higher currents, and since it is operative on both halves of the AC leakage current signal the device provides reliable protection against the possibility of dangerous electric shocks while avoiding spurious tripping.

Abstract: Determination of the mass of loose parts in the primary cooling system of the nuclear reactor is important in assessing potential damage. However, prior art systems could not give information on the weight of the loose part. This invention uses an acoustic transducer to generate an impact signal which has a unique signature represented by its frequency spectrum. It generates under predetermined conditions with objects, each of definite weight and form, a series of impact signals for reference purposes that are stored in a read only memory device (13). Then, the stored reference impact signals are read out one at a time and correlated with an actual impact signal from an unknown impacting object by comparing the frequency spectra (12), thereby to indirectly recognize the impacting object.

Abstract: A method for controlling a scintillation camera has a step of, under the control of a CPU (34), displacing a radiation source displacing device (36) to which is fixed a radiation source (PS) and obtaining a center of sensitivity of a photomultiplier tube (22) to be measured. After the center of sensitivity including the effects of the waveform shaping circuit is obtained, the radiation source (PS) is displaced in a plurality of directions relative to the center of sensitivity under the control of the CPU (34), so as to obtain an average photomultiplier tube response (PMT response) as a function of distance from the center of sensitivity of the photomultiplier tube (22). The CPU (34) compares the obtained average PMT response with a reference PMT response which provides an image of optimal uniformity to obtain data by which the average PMT response approaches the reference PMT response. Based on this data, the CPU (34) obtains parameters of the waveform shaping circuit to provide a response close to the reference PMT response.
