Abstract: A polymer is prepared by forming a mixture of 3-methacryloxypropytris(trimethylsiloxy) silane, methacrylic acid, cyclohexylmethacrylate, 2-hydroxypropylmethacrylate, m,p-styrylethyltrimethoxysilane, methyl methacrylate and a cross linker. A polymerization initiator is added to the mixture, and UV or thermal energy is supplied so that the mixture polymerizes to form a polymer that is transparent, hard, machinable and oxygen permeable. The polymer is cut into lenses, and the lenses are treated with acetyl chloride or another suitable chemical so that their surfaces become hydrophilic. The result is oxygen-permeable, hydrophilic, daily and extended-wear, hard contact lenses.

Abstract: Several problems of alignment associated with ink-­jet printers are alleviated by four aspects. In the first, a reverse bow (atB ) in the paper (12) is created for printing on single sheets of paper. The reverse bow (atB), which is in the transverse axis of the paper (12), forces the paper flat against the platen (14) by using the paper's own stiffness. 
     In the second aspect, the paper (12) and the carriage (30) are referenced to the same part (the carriage guide (10)). In this configuration, the paper (12) is urged against the underside of the carriage guide (10) off of drive rollers (18), through the reverse bow, and onto the platen (14), where it is printed. The carriage (30) is ref­erenced to the carriage guide (10) through a slider bump by means of a carriage shaft and gravity. 
     The carriage guide (10) comprises stiff thin sheet metal, which is closely-toleranced and has well-con­trolled dimensions. Thus, this part is good to refer­ence to, rather than molded-in parts, which are not stiff enough at the required thickness. Straightness is also difficult to achieve at the required thickness with plastic parts. 
     In the third aspect, the platen (14) is allowed to move substantially perpendicular to the plane of the paper (12) to accommodate thicker print media. 
     In the fourth aspect, the platen (14) is maintained a minimum fixed distance from the carriage guide (10) by bumps (38) to ensure that the paper (12) is not pinched between the carriage guide (10) and the platen (14).

Abstract: An electronic remote data recorder records pulses representing usage of a commodity such as, for example, water, gas or electricity from a plurality of consumers. The data from each consumer is stored in a respective data storage device. Each data storage device is associated with an interval data directory which stores the times at which significant events, affecting the data in the data storage device occurred. Thus, the data in the data storage device is compact, without requiring a contemporaneous time code for each data item. Data integrity is retained over a period of power outage in a non-volatile storage device. Initial, post-installation programming is enabled by comparing the data pattern in the non-volatile storage device with a predefined data pattern that is expected to exist once the apparatus has been programmed. A write-protect switch prevents programming during an incoming call after the initial programming. Programming from an external source may be permitted during a telephone call initiated by the data recorder itself. A telephone line-sharing device permits a plurality of remote data recorders to share a single telephone line without interfering with each other.

Abstract: The process consists in heating foods by sending overheated steam, for a given period of time, to a low thermal conductivity container (4) where the foods are held. The overheated steam is instantaneously produced by sending water to a vaporization chamber (7a) housing a first electrical resistor (8) designed to cause the vaporization of water. The wet saturated steam thus produced then reaches an overheating chamber (15a) disposed above the vaporization chamber (7a) and housing a second electrical resistor (16). Steam is overheated in the overheating chamber (15a) and afterwards sent to the container (4) through a delivery duct (18) running into the inside of the latter through a valve union means(19).

Abstract: Hitherto, the main part of a case and the cover of a case have usually been joined together via hinges arranged along the long side, so that such a case must be opened in the horizontal state. Particularly with cases for relatively large bowed or plucked stringed instruments, this requires a correspondingly large space. In the case according to the invention, the swivelling axis of the cover is located on the narrow side 6 on the side of the tip, so that the case can be folded open in the upright state. The cover 2 covers the bottom side of the instrument. In the open state, the cover has a slight curvature 16 pointing away from the main part of the case. In the rim region of the allround rib 5 of the cover, an allround inner gasket 17 and outer gasket 18 each projecting over the rim edge are fitted, the rim region of the rib of the main part 1 of the case fitting smoothly into the space 19 between the gaskets when the case is closed. <IMAGE>

Abstract: In an apparatus for the automatic calibration of gas sensors which, in particular, are combined in a gas detection system having a multiplicity of measuring heads which are connected to central evaluation electronics and carrying gas sensors, it is proposed for the purpose of facilitating perfect calibration by one man that when a calibration device in the preferred form of a calibration cap is placed on the measuring head in conjunction with the simultaneous provision of a flow of a calibration gas to the gas-sensitive region of the particular sensor a calibration signal is fed to the measuring head electronics and is relayed by the latter to the central evaluation electronics, which thereupon confirm the entry into the calibration phase, automatically recognise the particular calibration gas, automatically monitor the calibration process, automatically accept the particular calibration value, and in so doing continuously inform the operator, who is feeding the test gas, about the course of the calibration process. <IMAGE>

Abstract: In a hot runner channel construction set (1) for a stack mould, having needle valve nozzles (2) directed to opposite sides and in alignment with each other, the plungers (4) for driving the respective valve needles (3) are arranged coaxially to the latter in the hot-runner manifold, which for its part is divided into individual blocks (7), of which in each case one individual block (7) is assigned to one needle valve nozzle (2). In this arrangement, a main hot-runner manifold (6) protrudes into the region of the individual blocks (7) and its outlet openings (8) coincide, in the position for use, with the inlet openings (10) of the individual blocks (7), so that, in spite of the division of the hot-runner manifold, there is a continuous way through for the injection moulding material to the needle valve nozzles. The arrangement of the drive plungers in individual blocks of the hot-runner distributor have the overall effect of a small overall height and, after separation of the construction set, a good accessibility to all these individual parts, so that they are well able to be assembled and disassembled.

Abstract: Using the voltage-to-frequency conversion method and a device for implementing the method, an extremely fast and highly accurate digitisation of an input signal with a high degree of frequency deviation can be achieved by simple means. An input voltage (U@) raised into the positive range is integrated and compared as integrated voltage (UJ) with a reference voltage (UA) which can be varied in equidistant steps. The resultant difference voltage (UD) is applied via a control section (RG) to a voltage-controlled oscillator (VCO) which outputs a pulse repetition rate proportional to the output voltage of the control section (RG). The reference voltage (UA) is incremented with each pulse (P) so that it follows the integrated voltage (UJ) in a stairstep form. The pulse repetition rate of the pulses (P) generated by the voltage-controlled oscillator (VCO) is thus proportional to the input voltage (UE).

Abstract: A photocoupler apparatus comprises an output MOSFET (18), a series circuit of a first photoelectromotive force diode array (32) and a diode (34) and connected to the gate and substrate of the MOSFET (18), a series circuit of a second photoelectromotive force diode array (36) and a resistor (38) and connected between both ends of the diode (34), and a normally-ON drive transistor (26). The diode (34) is connected in a forward bias direction to the direction of a light current generated by the first diode array (32). When a charge current to be supplied to the MOSFET (18) is large, most of the light current flows through the forward-biased diode (34) to the output MOSFET (18) and is not influenced by the current limitation by the resistor (38). When the charge current decreases, the diode (34) is reverse-biased and the gate-substrate voltage of the MOSFET (18) is higher than a voltage generated across the first diode array (32). The transistor (26) is driven by a voltage produced across the resistor (34) and is kept at a state between ON and OFF, thus preventing charges accumulated between the gate and substrate of the MOSFET (18) from being discharged. When then first and second diode arrays (32, 36) stop generating photoelectromotive force, the charges accumulated between the gate and substrate of the MOSFET (18) are discharged through the resistor (34).

Abstract: A multilayer packaging structure for microwave food reheating applications or for sterilized hot filling is provided having an outer layer prepared from a blend of polyphenylene ether and a high impact polystyrene. The polyphenylene ether-high impact polystyrene layer is useful as a structural support layer and provides resistance to distortion and burn through during microwave reconstitution or hot filling. The PPE/HIPS blend layer serves to increase the high temperature performance of the coextruded structure without sacrificing the thermoformability characteristics generally associated with HIPS based monolayer or multilayer structures. The ethylene vinyl alcohol or polyvinylidene chloride layers act as the oxygen barrier to prevent food spoilage and the polyolefin layer acts as a moisture barrier.
