Abstract: A cellulosic substrate which is suitable for use as a mailer or envelope and which has at least one transparentized portion is provided. A method of transparentizing a cellulosic substrate by the application of a transparentizing material which provides enhanced toner adhesion properties, fast penetration rates and which is rapidly and completely cured by exposure to radiation is also provided. Further, these transparentizing materials may be applied without the need for solvents. These features thus permit continuous, in-line transparentization.

Abstract: In a preferred embodiment, a single motor drives both oil and refrigerant pumps in a refrigeration chiller, the motor and oil pump being disposed in the chiller's oil supply tank and the refrigerant pump being disposed exterior thereof. The refrigerant pump pumps liquid refrigerant to the chiller's compressor section so as to cool the motor by which the compressor is driven while the oil pump pumps oil to chiller locations that require lubrication when the chiller is in operation. A uniquely designed impeller permits low pressure liquid refrigerant in its liquid state to be reliably pumped to a location of use, without significant flashing, from a source location which is at a height only a short distance above the pump inlet. A stand alone refrigerant pump embodiment is also described.

Abstract: An improved case packer machine, of the type where containers are dropped through grid fingers to an empty case positioned on a lift table. The case packer machine of the present invention includes a flap opener which includes a pair of shoes mounted to an air cylinder. The shoes are extended by the air cylinder to contact and open the leading flap. The lifting table of the present invention is motor driven and controlled to limit the shock loading experienced by the containers as they are positioned within the cases. The lifting table includes a pair spur gears driven by the motor in meshing arrangement with a pair rack gears each mounted to a table and a novel gear guide to maintain proper engagement between the racks and gears and further to provide for backlash adjustment between the gears.

Abstract: A security document and its method of preparation are provided wherein a security image area on the face of the document is designated. The security image area comprises a two-dimensional array of security image blocks. Security image elements and the complementary security image elements in respective security image blocks are arranged such that the security image element and the complementary security image element portions occupy respective first and second percentages of each of the security image blocks to define respective characteristic relative occupation values (CROVs) for each security image block. The respective CROVs are substantially equivalent among a plurality of the security image blocks. A target CROV is established.

Abstract: A relay station utilizes the frequency hopping principle for the purpose of protection against intentional interference. Normally, the frequency hopping range available cannot be utilized for the frequency hopping operation because an indispensable minimum signal-to-noise ratio must be observed between the receiving frequency and the transmitting frequency of the relay station. In order to eliminate this disadvantage, the transmitter of the relay station is synchronized to the receiver by way of an interface connection and, with the aid of this synchronization, the desired frequency hopping in the entire available frequency hopping range for the transmitter and the receiver of the relay station can be controlled pursuant to observation of the required minimum signal-to-noise ratio.

Abstract: An endothermic reaction furnace includes one or more elongated reaction tubes defining therein an endothermic reaction flow path and a combustion flow path for providing heat to drive the endothermic reaction. The combustion flow path is arranged so that fuel and combustion air are separately heated by the heat inside the furnace preferably to significantly above their autoignition temperature before being combined in a combustion zone where they mix, autoignite and burn. The fuel is introduced into the combustion zone by a plurality of tubes having outlet ends arranged to produce annular shrouds of flame around each reaction tube that are directed countercurrent to the endothermic reaction product.

Abstract: A method of mounting a compressor above a heat exchanger. The method comprises the steps of: attaching a transfer device to the exterior of the heat exchanger where the transfer device has a lower arc surface and an upper sloped surface; positioning the compressor relative to a reference point to form a gap between the compressor and the heat exchanger; and placing a positioning device in the gap. The positioning device includes a lower sloped surface in slideable contact with the upper sloped surface of the transfer device. The method also includes the steps of: adjusting the positioning device so that the top surface of the positioning device contacts the compressor; and securing the positioning device to the heat exchanger and to the compressor.

Abstract: The invention relates to a wall connection for connecting a fitting (2) to a water network, with a connecting piece (3) having on the wall side a connection part (4) with an inlet duct (6), and on the fitting side a connection part (5) with an outlet duct (7).
