Patent BE-901394-A (BE)
Title: Variable capacity vat - has floating lid combined with secondary counter-lid and sliding seal
IPC: B65D88/46
Filed: 1984-12-27
Abstract: The cylindrical vat has a lid which rests on the surface of the contents. A V-section seal has the lower branch held against a rim on the lid, pref. with a retaining ring. There is a stiffening ring integral with the upper branch. A second, counter-lid, sits on the top of the seal pressing the sealing lip against the vat inner wall. - Removal of the contents via the drain pipe causes the lid assembly to fall with the fall in level. This is facilitated by the centre of gravity of the lids being below the level of the seal. The top of the inner lid is higher than the height of the drain pipe for max. removal of the contents.

Abstract: Abstract of the Disclosure A metal-to-glass-to-ceramic seal comprising a metal member including elongated portion and enlarged portion, a glass member bonded to the metal member and a ceramic mem-ber bonded to the glass member.  The ceramic member is in close proximity to part of the elongated portion of the metal member and over the enlarged portion so as to help protect the glass member from stresses resulting from bending of the metal member, to help prevent the metal member from being separated from the seal by an external tensional force, and to direct compressive forces that are parallel to the axis of the metal member such as crimping forces to the metal member rather than exerting shear forces on the glass bonds.  Part of the ceramic member of the seal may be metalized with a refrac-tory metal to facilitate the joining of the seal to the device to be sealed.  Use of a refractory metal for metalization of the ceramic member imparts several advantages to the seal includ-ing replacement of a portion of higher cost noble metals typi-cally used, ability to bond the metal to the ceramic member and fire the ceramic member at the same time, a strong   dif-fusion bond between the ceramic member and the metal layer that is substantially chemically resistant to most common elec-trolytes used in electrical devices, and ability to fuse a thin noble metal layer to the refractory metal metalized layer which reduces leaching during the joining of the seal to the electri-cal device.

Abstract: ABSTRACT OF THE DISCLOSURE An amplifier, for example, of a tape recording and reproducing apparatus, has a first smoothing power circuit for supplying DC power to operate the amplifying circuit when connected to an AC power source, and a second smoothing power circuit also adapted for connection to the AC power source for supplying DC power to operate other elements of the apparatus, such as, an oscillator for the bias signal to be applied to the recording head and/or an alarm for indicating the exhaustion of the tape, and also to energize a relay coil or the like by which change-over switches are actuated to their positions for the recording mode of operation of the apparatus, with the first and second smoothing power circuits respectively having relatively large and small discharging time constants when disconnected from the AC power source so that, if the smoothing power circuits are disconnected from the AC power source while the apparatus is in its recording mode, the change-over switches may be returned to their positions for the repro-ducing or playback mode of the apparatus while the amplifying circuit is still operative to produce howling.  Such howling is prevented by providing an amplifier, as aforesaid, with a holding circuit which detects the disconnection of the smoothing power circuits from the AC power source and, in response thereto, is effective to hold the change-over switches in their recording mode positions until the DC voltage applied to the amplifying circuit has declined sufficiently to render the latter inoperative.

Abstract: ABSTRACT        A combination door chime and detector responsive to the particulate products of combustion passing through multiple passageways formed in the chime cover. The door chime includes conventional spaced tone bars each cooperating with a tuned resonator chamber. A tone bar striker mechanism capable of single-note, two-note, and sustained-repetitive note striking of the tone bars is disposed between the tone bars. A photo-electric particulate products of combustion detector is also disposed between the tone bars. The conventional low-voltage door and chime transformer serves as a power supply for both the combustion detector and the striker mechanism. The closing of a first remote door chime switch generates a single-note single; the closing of a second remote door chime switch gener-ates a two-note signal; and the detection of the particulate products of combustion generates a sustained-repetitive note which serves as an intense audible alarm. An optional voltage comparator and signal gate serves to generate a pulsing repeti-tive signal with a relative large time interval between suces-sive pulses. This fourth signal indicates a malfunctioning of the particulate products of combustion detector.

Abstract: ABSTRACT OF THE DISCLOSURE      An artificial head assembly for a human femur consists of the head portion proper and a metal pin. The head portion is a sintered ceramic ball having a polished contact face of convex, spherical curvature and a blind bore tapering conical-ly inward toward the contact face. The pin is shaped for insert-ion of one  end into the hollow stump of the femur, the other end tapering conically at the same apex angle as the bore in the ball.    A knurling of the conical face of the pin reduces the compressive strength of the pin surface to less than the tensile strength of the ball so that the assembled head and pin can be sterilized without cracking the ceramic head port-ion because of differences in coefficients of thermal expans-ion between the metal and the ceramic material.

Abstract: ANTENNA WITH ECHO CANCELLING ELEMENTS     Abstract of the Disclosure In a Cassegrainian antenna, radiation transmitted from the feed system is reflected back as an echo to the feed from the subreflector.  In the prior art, a flat plate has been located near the subreflector to return an echo cancelling reflection to the feed in one frequency range.  In this disclosure, operation of an echo cancelling device which may be mounted externally on the feed side of the subreflector is extended to two frequency ranges by adding a reflective outwardly-flared wall-like ring around the perimeter of the flat plate.  The ring may include two conical segments sized to adjust the relative reflection amplitudes to obtain substantially complete cancellations over broad bandwidths at both frequency ranges.  The ring may also be stepped, or serrated, in cross section to avoid unwanted specular reflections and resonances.  The dimensions and location of the ring and plate are adjusted by an iterative experimental procedure to obtain optimum dual band cancellations for a given subreflector shape and illumination.  The ring and plate may be integral with the subreflector.

Abstract: PROCESS AND COMPOSITIONS FOR PHOTOPOLYMERIZATION                 ABSTRACT OF THE DISCLOSURE        The present invention relates to the use of aryl-glyoxalate, ring substituted   arylglyoxalate and heterocy-clic glyoxalate compounds as photoinitiators in the photo-polymerization of monomeric and polymeric compositions under the influence of actinic radiation.               BACKGROUND OF THE INVENTION        Photopolymerization of unsaturated compositions where-in a photoinitiating compound is included in the polymerizable mass is well known in the art.  The process has many advantages over thermal polymerization and is particularly useful where long holding life combined with rapid hardening at low tempera-ture is desirable.  Photoinitiating compounds must absorb light and utilize the energy so acquired to initiate polymerization.        A large number of compounds have been found useful as photoinitiators for the polymerization of unsaturated com-pounds.  Among those heretofore in most common usage in in-dustry are the benzoin ethers of primary and secondary alcohols such as methyl alcohol, ethyl alcohol, isopropyl alcohol and isobutyl alcohol.  Also, compounds such as phenyl glyoxal and 1-phenyl butane-1,2-dione are disclosed as photosensitizers in U.S. Patent No. 2,413,973.

Abstract: DRIVING TEST RANGE            ABSTRACT OF THE DISCLOSURE This invention relates to an automobile driving range so laid out that the ability of a driver to carry on normal motor vehicle driving activities can be automatically tested and graded. The driving range contains two-way traffic lanes separated bysensing switches so that a vehicle's presence in the improper lane is readily detected. Each vehicle temporarily has attached to it a radio transmitter having a very limited range and transmitting an identifying signal for the particular vehicle. Buried through-out the range are sensing loops which receive the transmissions from the vehicles and combine the vehicle identification with vehicle operation information being generated at the moment. In those portions of the driving range where driving tracks cross, the intersections can be controlled by stop signs, traffic lights, or any other traffic con-trol devices. Motion detectors at such intersections indicate whether or not a vehicle is in motion at any time. The loop adjacent such intersections receives transmitted information to identify the particular vehicles at the intersection. Similarly, portions of the track are arranged to provide areas in which vehicles may make U-turns, and other areas are provided for parking tests. The entire range has sensing devicesmounted within it which are connected to a data information center where all of the in-formation concerning each individual vehicle is gathered together to produce a final test result for each driver.
