Abstract: The invention relates to improvements in boluses for releasing a biologically active substance into a liquid environment. These boluses comprise a generally elongate core (25) surrounded by a liquid impermeable casing (11), (13), (15). In use, the casing has an opening at one (27) or both ends of the core and is progressively shed as the core retreats, to release the active substance at a rate which varies over at least one time period. The main improvement resides in that the bolus casing is (or at least some of its components are) sufficiently strong to retain integrity without disintegrating in the absence of any support provided by the core.

Abstract: A plurality of time delay circuits (1-1, 1-2,...), usually a dummy word line made similarly to a word line having a delay characteristics for charging and discharging, are provided in a memory device in place of a single delay circuit of prior art. A selection circuit (11) selectively drives one of the delay circuits (1-1, 1-2,...) and enables a gate connected to the driven delay circuit (1-1, 1-2,...) in a circulating sequence each time an input pulse is received. A gate circuit 12 detects a moment at which the output voltage of the dummy word line reaches a threshold level and then outputs an enabling signal to the readout sense amplifier. A noise coming-in closely before a normal signal is led to a delay circuit (1-1, 1-2,...) but disabled by the normal signal, thus having no effect on the signal. So, the invention is effective when the input signal is from an address transition detector (10) which, used in an asynchronous memory device, is apt to produce the above-described type of noise. And further, immediately after an enabling signal is outputted, a next address change is acceptable, because the next delay circuit is ready to function without being disturbed by the remaining voltage in the previously used delay circuit. Thus, both the increased speed of memory cycling and the increasedscale of integration can be achieved at the same time.

Abstract: A remote ion source (14) within an ICR mass spectrometer which provides an enhanced trapping (within an analyzer cell (12)) of ions formed within that remote ion source (14). In a preferred embodiment, trapping enhancement is accomplished by means of magnetic perturbations of the magnetic field within the analyzer cell. The perturbations may be established by ferromagnetic means (30) or electromagnetic means (31) or by the use of permanent magnets to form a magnetic bottle. Ions formed within the remote ion source (14) are extracted from that source by an electrostatic lens (16) and directed toward the analyzer cell (12) along the Z axis of the spectrometer magnetic field. Deceleration lenses (37), external to the analyzer cell, may be employed to further enhance the trapping capability of the analyzer cell (12). In some modes of operation, a ramped deceleration potential may be applied to the declaration lens for "grouping" of ions of different masses for analysis. Provision for mass selection is also made within the spectrometer disclosed herein.

Abstract: A high speed, high performance integrated circuit packaging structure that may be used for emulating wafer scale integration structures. The preferred embodiment comprises an interposer (9) having a base substrate having alternating insulation and conductive layers thereon, wherein a plurality of the conductive layers are wiring means which are adapted for maintaining an extremely low noise level in the package. The low noise level and low resistance and capacitance of the wiring means allows a plurality of discrete semiconductor segments (32) to be mounted on and interconnected by the integrated circuit package with a significantly reduced number of drivers and receivers than required by Rent's Rule. Each integrated circuit structure (9) of the present invention emulates a large chip or wafer scale integration structure in performance without having to yield the large chip or wafer, and without redundancy schemes. A plurality of these integrated circuit packaging structures (9) are combined by decals (29, 31) to form a central processing unit (1) of a computer or a portion thereof. In an alternate preferred embodiment, the base substrate of the interposer is made of silicon and any required drivers are formed therein, thus substantially eliminating the need for any drivers on each of the discrete semiconductor segments (32).

Abstract: A control apparatus for a refrigerating appliance com­prises a commutator controlled by a timer for cyclically commutating from a first position, in which electric power is supplied to a compressor motor, to a second position in which power is supplied to an evaporator defrosting resist­ance heater via a thermostat commutator when the latter is in a position corresponding to a low temperature of the evaporator. The thermostatic commutator switches to a second position in response to sensing a higher temperature of the evaporator. The timer is supplied with electric power via the controlled commutator when the latter is in its first position, and via the series-connection of the two commutators when in their second positions. The auto­matic defrosting operation is thus carried out in accord­ance with the actual condition of the evaporator.

Abstract: The chair has a seat or seat portion equipped with a balance and its linkage structure has links fixed in articulated manner to a support arm and to which there is articulated a balance device in parallelogram-like manner. A slide is slidingly guided on the balance device and is connected by means of a thrust rod to an extension arm of the backrest-side link. The slide is also connected to one end of a spring element, the other end of which is supported on the balance device. The linkage structure is supported on the backrest by means of a backrest strut articulated to the slide. The seat and backrest portions of the chair frame can be constructed as a plastic shell with a knee-side bending joint and a further bending joint between the seat portion and the backrest portion. Due to the construction of the chair frame to incorporate a balance device, as least part of the forces exerted by the occupant or user of the chair can be absorbed by the balance device, so that the spring element can be made smaller and therefore less expensively, and there is also no need to adjust or adapt the spring element to different body weights of the users of the chair.

Abstract: Provision is made for spatially stabilizing standing capillary surface waves (62) in fixed and repeatable locations with respect to stationary external references. For spatially stabilizing such a wave on the free surface (23) of a volume (24) of liquid, the wave propagation characteristics of the free surface of the liquid are periodically varied in a spatially stable manner at a spatial frequency equal to the spatial frequency of the standing wave or a subharmonic thereof, thereby locking the crests (64) and troughs of the standing wave in predetermined spatial locations. A spatially periodic pattern of notches (82) in a wall (83) or base plate bounding the free surface of the liquid may be employed to physically modulate its wave propagation characteristics at a suitable spatial frequency. Alternatively freely propagating secondary capillary surface waves may be launched from spatially periodic sites along the free surface of the liquid to actively modulate its wave propagation characteristics at the desired spatial frequency.
