Abstract: A food heating or cooking appliance has at least one electrical heating element within its interior that is adjustable in position so as to be able to be moved close to thin or small food items under the control of a manually actuated control. A separator plate that extends across the interior chamber of the appliance from side to side and from front to back is movable with the heating element to enable adjustment of the volumetric size of the cooking chamber containing the heating element and the food to be heated or cooked. A manual actuator, a knob or lever, for example, moves the heating element and the separator plate through a motion transfer bar that extends across the width of the appliance and is attached to a linkage on each side of the appliance to communicate movement to a pair of movable supports supporting the rod-like heating element at each of its ends and the separator plate at opposite edges.

Abstract: An instructional board of computer game defines a path of movement for a number of game “pieces” that are moved along the path a number of “stops” as determined by a die or other random device. Associated with the stops and color or otherwise visually coded therewith are sets of cards bearing the questions all relating to a subject of instruction. Game rules call for a player or team whose piece lands on a stop “owned” by another player or team to answer a question printed on the face of the card of the other player. A correct answer earns points for the answering player or team as well as for the team or player that poses the question. “Free” stops imprinted on the board or programmed into the computer display are locations where the game rules call for a player whose piece lands there to obtain points without answering a question because the “free” stop is associated with worthwhile activity the player is deemed to have participated in.

Abstract: Operating room fires are prevented by a safety interlock that disables instrumentalities (such as an electrical cautery device) capable of igniting a fire in the presence of oxygen and a fuel source or combustible material such as skin, hair and/or prep agents containing alcohol. Removal of, e.g., the cautery device is sensed by a sensor to disable an oxygen source supplying oxygen to a patient and set a timer. Electrical activation of the cautery device only is permitted upon timing-out of the timer, which timing out is set for a time when oxygen will have cleared from the patient's immediate surroundings. A further safety feature is provided in a further timing, by the same or another timer, of the time during which the patient has been deprived of oxygen. After a short duration, then, the cautery (or other) device is denied electrical power and oxygen is permitted to flow again to the patient.

Abstract: A low profile magnetic element used in cooperation with a multilayer printed circuit board has two or more core arms penetrating the board from one outer surface to the other and a series of magnetic core elements, at least one on each side of the board, bridging pairs of the core arms to form a closed, unbranched flux path. Series-connected windings form a transformer primary and are wound on the core arms that penetrate the board. Parallel-connected windings form a transformer secondary and are also wound on the core arms. The series-connected windings and the parallel-connected windings may be buried windings printed on internal surfaces of the multilayer board. The connected in series primary windings all have the same number of turns and the parallel-connected secondary windings all have the same number of turns. The parallel secondary windings are connected in current additive fashion to afford a high current transformer output.

Abstract: A coil form for forming an inductive element (10) includes a coil body (2) and at least one, for example three separating plates (3). The coil body (2) has an opening (4.1) and includes two portions, a coil portion (6) and a flange portion (7). To put the inductive element (10) together, the separating plates (3) are pushed over the coil portion (6) of the coil body (2). The separating plates (3) divide the surface of the coil portion (2) into a plurality of coil areas where the coil or the coils of the inductive component (10) can be provided, for example by winding an isolated wire around the coil portion (6) in a coil area. The separating plates are made of metal and form another coil of the inductive component. Afterwards, the core of the inductive component is installed by fitting the two E-shaped core parts (11.1, 11.2) together such that the middle leg (13) of each core part (11.1, 11.2) is inserted into the opening (4.1) of the core body (2).

Abstract: A system and method of proxy domain name registration permits a would-be domain name registrant anonymity. A registrar affords customers the opportunity to use the proxy registration. If the customer seeking registration of a domain name requests, the registrar obtains contact information needed for registration from a proxy entity established for this purpose. The registrar completes the registration of the domain name with the appropriate registry (i.e. “.com, .net” etc.). The contact information published in WHOIS is that of proxy entity. Contractually the customer is afforded control over the domain name. Emails intended for the customer are received by the proxy entity who may filter them if the customer requests. Emails sent by the customer are sent to the proxy entity who in turn sends them to the indicated addressee.

Abstract: A DC/DC power supply with two transformers (10, 20), which for example are connected in parallel on the primary and in series on the secondary side, comprises two passive, non-dissipative snubber circuits (1.1, 1.2). Each snubber circuit comprises a series circuit formed by a capacitor (3.1, 3.2) and a diode (4.4, 4.7), which is connected to the output capacitor (13) of the power supply. The transformers are interleaved with a push-pull configuration. On the secondary side, the power supply has an output choke (12, 22) and two output rectifiers (11, 21) are connected to the secondary winding (14, 24) of each transformer. Each snubber circuit further comprises two additional diodes (4.5, 4.6, 4.8, 4.9), one electrode of these diodes being connected to the joint electrode of the snubber capacitor (3.1, 3.2) and the first snubber diode (4.4, 4.7) and the other electrodes being connected respectively to an end of the secondary winding (14, 24) of a transformer.

Abstract: The invention relates to an avalanche radiation detector comprising a semiconductor substrate (HK) with a front side (VS) and a back side (RS), an avalanche region (AB) which is arranged in the semiconductor substrate (HK) on the front side (VS) of the semiconductor substrate (HK) and a control electrode (R) for adjusting the electric field strength in the avalanche region (AB). It is proposed that the control electrode (R) is also arranged on the front side of the semiconductor substrate (HK).

Abstract: A dispenser for liquid consumables locates a store of the particular liquid at a location remote from the dispensing location. The dispensing location is typically located above a counter and may include a relatively narrow stem that brings a flexible liquid delivery tube up to a valve. Valuable counter space is conserved. One or more disposable, flexible and collapsible bags contain the store of liquid and communicates with the dispensing location via the liquid delivery tube. Confined in contact with each flexible bag is an inflatable bladder to which compressed air is routed. Liquid is dispensed each time the valve opens. When exhausted the flexible bag is replaced. Safety interlock switches vent the inflatable bladder to prevent its expanding explosively upon opening of the location where the liquid containing bag will replace the empty. Where the liquid needs temperature control, temperature control means are provided where the liquid is stored.

Abstract: An improved method for the design and development of high performance hybrid devices having biological and nonbiological components. A figure of merit is developed for the biological component or components. The component is subjected to various environmental variables as it or its biological source organism is grown. The biological component is force adapted to cause its figure of merit to reach a goal or an acceptable measure. The biological component is used in hybrid constructs that may be nanostructures, given the small size of the biological parts. In one specific embodiment, force-adapted chlorosomes of C. aurantiacus enhance performance of a silicon photovoltaic cell. The bacteria, Chloroflexus aurantiacus (C. aurantiacus), strain J-10-fl, has the A.T.C.C. designation number 29366, having been deposited in July, 1976.

Abstract: An extrusion control system that controls the cross section and viscosity during extrusion of even hard to control plastics like polyurethane. Cross section, A, is determined by measuring volumetric rate of deliver of melt through a gear pump V/t and the speed of the extrudate at a puller N/t. The cross-section area, A=(V/t)/(N/t), is controlled by controlling the puller speed. Pressure drop across the die, P, and the volume of melt delivered by the gear pump are measured and a term indicative of the viscosity of the melt is determined based on Vs=(KP)/V, Vs being the viscosity and K being a constant dependent on the size and shape of the die orifice. Viscosity variations are compensated by varying heat applied to the melt.
