Abstract: A balloon pump includes a cylinder having an outlet end and a piston adapted to reciprocate within the cylinder. One-way outlet and inlet valves are associated with the pump for allowing air to exit the cylinder outlet end only when the piston moves toward the outlet end and enter the cylinder only when the piston reciprocates away from the cylinder outlet end. An elongated piston drive member or base is connected at one end to the piston with the other end extending out of the cylinder at the end opposite the cylinder outlet end. A biasing arrangement acts between the cylinder and the piston to bias the piston away from the outlet end of the cylinder. With the pump positioned vertically and supported on the elongated piston drive member, the biasing arrangement raises the cylinder to perform a return stroke so that the pump may be operated simply by pushing down on the cylinder.

Abstract: The present invention relates to a method and an arrangement for supplying direct current to a telephone line. According to the invention, the current supply characteristic is programmable. The arrangement comprises a direct current supply circuit which detects the line voltage and supplies a line current in accordance with a preprogrammed current supply characteristic. The circuit includes a first more high-voltage part and a second more low-voltage part, in which programming of the current supply characteristic takes place. For the purpose of achieving programming, a first resistive component having a programmable resistance is arranged essentially parallel with a capacitor in the second part. The first resistive component determines the supply resistance of the circuit for low line currents.

Abstract: The invention concerns a process for the treatment of wastepaper, carried out for the most at a high consistency of at least 13% in the first stages, beginning the dissolution (soaking) and including a coarse sorting stage. The invention is characterized in that in the case of wastepaper containing a share of at least 40% of deinking wastepaper provided with printing inks the three first process stages, namely in this order of soaking, coarse cleaning and the further extensive dissolution of the wastepaper, take place at a considerable reduction of the wastepaper shreds to the usual speck size at a consistency of at least 13%, and the soaking under considerable addition of dissolving chemicals, and that the wastepaper including essentially all heavy contaminations, such as part of wood, glass, plastic or metal contained in the wastepaper, including pieces of metal straps of the wastepaper bales, is fed to the process.

Abstract: A high definition television system. Each pixel of the resulting television picture is represented by three equations which describe that pixel state over a predetermined time. Only coefficients of those equations need to be transmitted. Only those pixels which have an equation which completely changes need to be transmitted. Hence, at any given time, only a very small percentage of information needs to be transmitted: the rest of it follows the pre-sent coefficients.

Abstract: Transmission quality of an ongoing call in a mobile radiotelephone system is monitored by measuring parameters indicative of transmission quality, evaluating transmission quality according to the measured parameters, repeatedly measuring the aforementioned parameters at intervals, and repeatedly evaluating transmission quality according to the measured parameters at a time interval variable according to the results of the previous evaluation. Effectively, the calls in progress are divided into different classes according to transmission quality with some classes requiring monitoring relatively frequently and other classes requiring monitoring relatively infrequently. Alternatively, the waiting interval according to which a call is monitored may be determined on an individual cell-by-cell basis.

Abstract: in a telecommunication network structure, all functions related to traffic control, including functions for controlling, originating and terminating connections, take place in a mobile service control point while the physical set up of the connections take place in mobile service points which are subordinated to the mobile service control point. Subordinated units are connected to each mobile service point with trunks. A signal net is transferring traffic control signals, including connection control signals, to the subordinated units in which the connections are made, using the trunks.

Abstract: An improved stud poker game which requires no decisions from the player after the initial bet is placed. Each hand has one guaranteed wild card that appears at a card position which is predetermined, and shown to the player, before the player's cards are dealt. In addition to the one guaranteed wild card, all like-valued cards in the hand are also wild. Also, there are a number of novel and entertaining ways to determine the wild card position. The game is adaptable to both video play and table play formats.

Abstract: A convenient golf game with adjustable out-of-bounds markers which has enclosed tee areas with doors that can be manually or automatically moved to coincide with particular out-of-bound markers. The doors may be pivoted or slidable. Golf shots can be made to a green area that has a number of greens.

Abstract: A disk drive in which the radial alignment, track zero alignment, index to data timing, write current, asymmetry and threshold dropout can be electronically adjusted. A plurality of programs stored in random access memory run a plurality of adjustment procedures used to control the electronic adjustment functions of the disk drive. An alignment disk read by the disk drive provides alignment data for the radial, track zero and index to data alignment procedures. A microstepper circuit in the disk drive allows the read/write heads to be moved in discrete steps of approximately 1/126 of the track pitch for electronically adjusting the radial and track zero parameters. The index to data alignment is set by generating and storing an artifical index offset value. The write current and asymmetry adjustment procedures utilize digital to analog convertors (DACS) to vary the voltage supplied to the read/write heads. The threshold dropout procedure utilizes a DAC to control the output of a pulse detector.

Abstract: A vestibule block or interior furnace wall utilized in a diffusion furnace for manufacturing semi-conductors, integrated circuits and the like, and which is made of refractory or ceramic material, is treated on its surface with a suspension of fine particulate of a glass frit composition comprising an alkali earth metal alumino silicate, and is thereafter heated above the transition temperature of the alkali earth metal alumino silicate. Vestibule blocks and interior surface walls which have been treated in the above-described manner are highly abrasion resistant on their surface, generate virtually no particulate matter under conditions of ordinary use in the semi-conductor manufacturing processes, and generate significantly less particulate matter when tested in an abrasion test against vestibule blocks of the prior art.
