Abstract: A container for loosely housing dual-in-line components 4 comprises an elongate tubular member 1. The tubular member is substantially U-shaped in cross-section and includes a hollow central portion 2 for receiving the body of the components, and flanking portions 3 for receiving the legs 5 of the components. The tubular member is so shaped that the components can only touch the tubular member in certain predetermined locations 8, 9, 10, and to protect the components from static discharges on contacting the container, only these locations need be made conductive, the remainder of the container being of transparent plastic. 
     In one embodiment the container may be provided with conducting ribs (13, Figure 6) on the outside so that when two such containers come into contact it is not possible for two non-conducting parts to come into contact so generating static.

Abstract: In a cellular array processor at least two of the plurality of processors in a row cooperate together as an address generator so that large amounts of memory external to the array chip may be addressed and in addition so that an address may be generated onboard for use by the DRAM memory associated with each processor. Based on this structure, a memory with an internal organization that is 256-bits wide may be connected to 16 16-bit processors which would require 256 bits of data. In so doing, a vast number of pins are saved, that is 256 bits of data out of the memory and 256 bits of data into the processing cells by combining the processing cells and memory on the same chip. It is significant that exactly one design of a processing cell may provide both a data processing element and an address processing element. In this way, these cells are interchangeable to maximize the yield and reliability of the device. A single address from the address generator addresses the entire onboard DRAM so as to use the number of address generators required and to reduce the amount of address decode logic required as well as minimizing power dissipation in the DRAM portion of the chip.

Abstract: The present invention relates to a composition comprising the reaction product of thiocyanogen or a thiocyanogen halide and certain α,β-unsaturated ketones, e.g. chloranil, and solutions of the reaction product in an inert solvent. The composition can be prepared by adding to a thiocyanogen or a thiocyanogen halide solution in an inert solvent certain conjugated unsaturated ketones. Unlike the thiocyanogen or thiocyanogen halide solutions, the composition of this invention does not polymerize over an extended period of time. Thus, the product can be packaged and shipped whereas the known thiocyanogen solutions are unstable and must be used within a relatively short period of time before they polymerize and form a brick-red precipitate, thereby becoming inactive. 
     The composition can be used to treat the surfaces of polymeric articles to provide a more adherent surface for paint.

Abstract: Optical heterodyne receivers for ASK-, PSK-, FSK-, and DPSK-modulated signals are disclosed which contain a polarization controller. The receiver contains a unit (Q, Q') which works on the difference-detector principle to eliminate the shot noise of the local oscillator (LO), which emits circularly polarized light. It further includes a quadrature demodulator (D, D', D'') which, besides delivering the useful signal (N), provides polarization control signals (SE, SW) with which the ellipticity and the polarization angle of the received light (ES) are adjusted in such a way that the received light (ES) is linearly polarized at an angle of 45 DEG  or 135 DEG .

Abstract: Mirror objective comprising two reflecting surfaces (2, 3), a primary mirror and a secondary mirror, respectively, arranged in connection to a lens (1). The primary mirror and the secondary mirror together with the lens are arranged to form an excentric radiation path through the mirror objective. The optical axis of the mirror objective follows an N-shaped path through the objective and central diaphragming is avoided. The object and consequently the image are situated outside the geometrical axis of the mirror objective. The mirror objective shows a short distance between the object and the image and is, for example, suitable for reading bar symbols, letters and digits, and for reading optical discs or similar storage means. The invention also relates to an optical arrangement com­prising two mirror objectives as described above, one of the mirror objectives being used for illuminating, the other mirror objective being used for imaging.

Abstract: A copying machine with an automatic exposure device in which the density of an original is detected by irradiating an original by light from a lamp (4a) and detecting reflecting light with an optical sensor (6a), and in accordance with the detected signal the exposure amount of the lamp is adjusted by means of an automatic voltage adjusting circuit, is equipped with a heater control unit for controlling the energization of a fixing heater (20b) for fixing a toner sensible image which has been transferred onto paper. A processing circuit for controlling the automatic voltage controlling circuit and heater control section, acts to maintain the energizing state of the fixing heater (20b) in a single state, while the operation of detecting the original's density is run with the lamp operating. In this way, fluctuation in the voltage to the lamp due to switching of the fixing heater is prevented from occurring at the time of detecting the density, and the intensity of light from the lamp is kept constant.

Abstract: A synthetic gene encoding an exogenous protein has been assembled and inserted into a eucaryotic secretion expression vector containing the cytomegalovirus immediate early (CMV-IE) transcrip­tional regulatory region, any one of a variety of mammalian secretory signal peptides and a portion of the bovine growth hormone gene encoding transcription termination sequences. The recombinant plasmid encodes the amino acid for the fusion protein that contains the mammalian secretory signal peptide and the amino acids of the protein to be secreted. This plasmid, when transiently introduced into cultured mammalian fibroblasts, directs the synthesis of the fusion protein, the subsequent proteolytic removal of the secretory signal peptide and the secretion of the protein into the culture media. The recombinant proteins produced by these cells are biologically active.

Abstract: The hydraulically impulsed screwdriver has a motor (3) and a striking mechanism (4), which possesses a cylinder (14, 16, 17) connected to a motor shaft (9) so as to be fixed in terms of rotation, and an output shaft (19) rotatable relative to it. The output shaft penetrates the cylinder (14, 16, 17) and is arranged eccentrically with respect to the cylinder space (24). To switch off the screwdriver, a switching-off device (54, 55, 35), actuated as a function of the pressure of the hydraulic medium in the cylinder space (24), is used. The criterion employed for the switching-off time is the pressure in the cylinder space (24) of the striking mechanism (4), which is proportional to the torque prevailing in each case. The screwdriver is switched off only when the corresponding pressure and thus the desired tightening torque is reached. <IMAGE>

Abstract: A data distribution system for the timely, efficient and reliable distribution of data to an unlimited number of remote receiver installations. A data source (100) assembles data packets, and upon filling or after the lapse of a predetermined interval of time, broadcasts a respective data packet to all receivers (120) and recovery means along a communication network. Each receiver is intelligent, in that it copies the data packets into a buffer and has the responsibility of selecting out data needed to perform the receiver's intended functions. As a result, intermediate data selecting and routing means between the data source and receivers are avoided, resulting in data delivery which is both rapid and timely. For reliability, each receiver monitors the sequence numbers of the data packets which have been received and, also, whether a data packet is received at least as frequently as the predetermined interval of time. Any data packet which a receiver determines as missing, can be obtained from the recovery means which stores a library of the received data packets or which can retrieve the missing data packet from the data source.
