Abstract: Method and apparatus for forming lateral collars at a preferably oval lateral cutout of a sheet metal tube by means of a holding mandrel for the tube and a collar-forming die which is placed on the cutout and through which a collar-forming cone is pulled. To avoid unwanted deformations and bulging during the formation of the lateral collar, a large area of the surface of the tube (1) around the cutout rests on the holding mandrel (4), half of which is overlapped, as far as the largest diameter transverse to the lateral collar and approximately over its entire length, by a half-shell (8), in which the collar-forming die is formed. The length of the holding mandrel corresponds approximately to three times the diameter of the lateral collar (3) and is designed in such a way that, outside the opening of the lateral collar, the entire inner surface of the tube (1) rests against the holding mandrel (4), and the collar-forming die (8), of approximately the same length as the holding mandrel and functioning as a supporting shell, surrounds the said mandrel and the tube placed on it as far as the mandrel diameter lying transversely to the lateral collar, and the collar-forming cone (11) is provided with a central through hole (13) for receiving the free end of the piston rod (16) of the hydraulic cylinder (15), the said free end being couplable to the collar-forming cone (11) by means of projecting sprung radial pawls (17). <IMAGE>

Abstract: Large size packings of napkins, paper rolls, quilts etc. normally appear as tight plastic sheet packings of a block-­like shape. As a carrier handle is used a strong strip of sheet material which extends across a side panel of the packing, what is disadvantageous for the visual impression of the packing. A carrier handle cannot be formed direct in the packing sheet, as the packing will then no longer be dust proof. According to the invention the handle is made in that manner anyway, but inside the handle area a barrier layer (12) is provided in order to make the packing dust proof. Preferably a carrier handle strip portion (6) is prepared between easily breakable weakening lines (4), whereby the handle panel of the packing may show a high quality stamp regardless of the handle.

Abstract: A package for foods is disclosed and comprises a container (1) having a peripheral flange at its mouth. The container is made of or lined with a plastics material so as to provide a plastics surface at the flange. The container is covered by a lid (3) which is heat-sealed to the flange. In order to be able to open the package easily, especially when it is hot, a tear-strip (5) of material extends across at least the flange and is secured to the lid by a heat-seal. The tear-strip presents a tab (6) for engagement by the fingers of a user, and, in order to ensure that the lid can be torn effectively by the tear-­strip, the bond between the tear-strip and the lid is chosen to be at least as strong as the bond between the lid and the flange.

Abstract: A semiconductor device including a heterojunction bipolar transistor in which the front surface of a base layer (13) and the surface of an emitter-base junction between an emitter layer (14,15) and the base layer (13) are covered with a high-resistivity layer (17) of compound semiconductor containing at least one constituent element common to the emitter layer (14,15) and the base layer (13). 
     The transistor is formed by the emitter (14,15) and base layer (13) together with a collector layer (12) on a semiconductor substrate (11). The base layer (13) extends to a base contact layer (113) with an electrode (111). 
     In this way, it is possible to overcome to a significant extent the lowering of a D.C. current gain (the emitter size effect) attributed to the reduction of an emitter size attendant upon the microfabrication of a device.

Abstract: In a division circuit, a dividend register (7) and a remainder register (14) are connected so that a bit in the MSB of the former is shifted to the LSB of the latter. Higher bits of an N-bit divisor are monitored by a detector (18) and a zero-detect (ZD) signal is generated when they are all "0"s. In the presence of the ZD signal, subtraction is performed by an N/2-­bit subtractor (28) between lower-bit data of a divisor and data in the remainder register and, in the absence of the ZD signal, first subtraction is performed between lower-bit data of the divisor and higher-bit data of the dividend register (7) and second subtraction is performed between higher-bit data of the divisor register and data in the remainder register (14). A "1" is written into the LSB of the dividend register (7) either in response to a "1" in the MSB of the remainder register (14) or when no borrow results from subtractions. In the presence of the ZD signal, the result of each subtraction is stored in a first latch, the remainder and dividend registers are one-bit shifted and the remainder register (14) is loaded with the stored data when a "1" is stored into the LSB of the dividend register. In the absence of the ZD signal, the results of subtraction are respectively stored in first and second latches (12;71,8;72), and the registers (14,7) are shifted and loaded with the stored data when a "1" is stored into the LSB of the dividend register (7). A quotient and a remainder are derived from the dividend and remainder registers after subtraction is repeated N times.

Abstract: Disclosed herein is a laminated film comprising a polyester film containing minute closed cells and having a density of 0.40 to 1.30 g/cm³ and a polyester film having a density of more than 1.30 g/cm³ laminated on one side or both sides of the polyester film containing minute closed cells. 
     In the laminated film of the present invention, the surface smoothness, which is a serious defect of a conventional film containing a large number of minute closed cells, is improved and the ink adhesive property is also improved, thereby enhancing the printing suitability. The breakage during the stretching process of film formation is reduced and the film forming properties are improved. Thus, the productivity was enhanced, thereby enabling the film to be supplied to the market at a low cost. Application of the film to various fields is enabled and the industrial value of the film is very large.

Abstract: An apparatus and method for flow analysis dur­ing collection of a urine sample are disclosed, and for simultaneously maintaining the sterile urine sample for use in clinical and microbiological analysis. A dispos­able vessel (90) for collecting the urine is mounted on a commode adapter, and includes a variable capacitor (220), with a capacitance value which varies with the amount of urine (or other fluid) in the vessel. The variable capacitor forms a part of a capacitance bridge (340), which is used to produce a potential relating to the varying capacitance value. A microprocessor (470) controlled by a clock is used to periodically sample the varying capaci­tance value as fluid flows into the vessel, and thereby determine the flow rates of the fluid and other useful values. A tube (180) is provided which communicates with the interior of the vessel for drawing off a sterile sample (200) of the urine for laboratory analysis, and a drain (140) is provided which is operable without contacting the urine. 
     The flow rates determined by the microproces­sor are subjected to post-processing, wherein retrospec­tive averages of the flow rates are taken for a certain block of predetermined intervals during which the rates were being generated, prospective averages are deter­mined for a second block for such predetermined inter­vals with the second block having an overlap with the first block, and combined averages are generated by merging the retrospective and prospective averages for the overlap.

Abstract: In a cellular data transmission system non-interfering digital communication channels are added to existing analog or digital voice communications channels in the system by utilising frequency space between channels made possible by the co-channel and adjacent channel frequency co-ordination procedures. Interference is prevented by reduction of power, selection of frequencies, proper modulation and demodulation techniques, and unique allocation to the channels in frequency and location. The system is also applicable in general to the insertion of narrow frequency bandwidth channels in any existing communications system using co-channel and adjacent channel frequency allocation strategies.
