Title: Strip baggage tag
Inventor: DIEMERT KURT
IPC: G09F3/10
Filed: 1992-10-15
Abstract: A strip baggage tag (1) includes a tag part (3) which can be written on and attached to an article of baggage, and a control section (4). The control section (4) includes a tear-off part (5) which can be detached from the tag part (3) along a transversely extending separation line (6). The tag part (3) and the tear-off part (5) have respective back adhesive areas (11, 11'') coated with a pressure-sensitive adhesive on both sides of the separation line (6). The adhesive areas (11', 11'') are covered by a one-piece lower web section (14) which forms part of the control section (4) and is developed for carbonless copying on its top facing the tag part (3). The lower web section (14) is continuously separation-active (17) except for a partial region (18) below part of the adhesive area (11'') on the tear-off part (5) of the control section (4). This partial region (18), which is made separation-inactive for instance by corona treatment, forms an attachment bridge so as to form a firm connection between the lower web section (14) and the tear-off part (5), so that they together form the control section (4) for being adhered to an airplane ticket for identification of an article of baggage, after subsequent exposure of part of the adhesive area (11'').

Abstract: IMPROVED ROCKING ARM SAW     ABSTRACT             An improved rocking arm saw disclosed for use in one mode with an operating handle as a pull-through power saw for accurate cross or angle cutting while being readily convertable by removing the handle ot a table saw for ripping or groove cutting.           The saw in its rip-cutting operations may vary the depth of cut and may vary the angle of cut in a quick and easy manner.  The saw in its free standing form comprises a cutting platform and work table top.  The table top is thus maintained free from obstraction since the blade is protectively shealded beneath the cutting surface upon the operator releasing the oper-ating handle. a carrying open-top box is used also as base to raise the platform surface to a hight enable the operator to work in a standing up position and as a saw dust collector.  The saw is transportable for work at the job site.

Abstract: 2092996 9206068 PCTABS00011 Applicants describe the synthesis of tamoxifen derivatives, most particularly halo, halo alkyl and hydroxy tamoxifen derivatives, wherein with the native tamoxifen molecule includes a substituted chemical group positioned on the aliphatic chain of the tamoxifen molecule. Particular halogenated tamoxifen derivatives of the invention include chloro, bromo, iodo and fluoro tamoxifen derivatives, and corresponding lower alkyl halogenated forms. The halogenated tamoxifen derivatives possess superior binding affinities for estrogen receptor rich tissues, such as uterine tissue and breast tissue, relative to unsubstituted native tamoxifen. In particular, the fluoro and bromo tamoxifen derivatives have potential use in imaging estrogen receptors by PET whereas the iodinated tamoxifens have potential use in imaging estrogen receptors by SPECT. The bromomethyl tamoxifen derivatives are demonstrated to bind estrogen receptors with the greatest enhancement of binding affinity over native tamoxifen. Rapid and efficient methods of preparing the tamoxifen derivatives having high specific activity (>6 ci/µmol) are also disclosed. Aliphatic chain substituted tamoxifen derivatives are shown to possess greater estrogen receptor binding affinity and more potent tumor cell inhibition than tamoxifen or tamoxifen derivatives substituted at other locations on the molecule (i.e., non-aliphatic chain substituted tamoxifen). The tamoxifen derivatives of the present invention may advantageously be used as anticancer therapeutic agents to halt estrogen-receptor positive tumors, such as those of breast and uterine tissue.

The oscillator (Fig. 3) and the filter (Fig. 4) are implemented in a manner where the monolithic pattern elements setting the fundamental control parameters (time-period and time-constant respectively) are of the same type. Monolithic capacitors are used as one of the common passive elements between the oscillator and the filter to set the time-period and time-constants, respectively, adjustable through adjustment of control currents (losc; Ix). The monolithic implementation of the Control Block (Fig.  3, Fig. 4 and Fig. 7) is such that by tuning the oscillator frequency to he appropriate value through setting of the respective control current (losc), the filter time-constants also are appropriately set to satisfy the Nyquist criteria for a sampling rate referenced to the oscillator frequency.

Title: Salt chicken (hakka style) apparatus
Inventor: PENG SHU RONG
IPC: A47J27/14
Filed: 1993-12-30
Abstract: This invention relates to an apparatus used in heating a media, such as salt, to a certain temperature, then, when ready, the heated media is used to bury a food item, such as chicken, for cooking. The apparatus comprises an internal chamber including a rotor having impellers for agitating and mixing the salt during heating to prevent burning and to evenly distribute the heat. Suitable alarms are also provided to alert the user or chef when the salt has reached the desired temperature, then the chicken is buried with the heated salt for cooking. The chicken can be buried in a separate receptacle, or, if the apparatus is large enough, within the internal chamber.

Title: Fire extinguisher sprinkler construction
Inventor: HOENING BRIAN T
IPC: A62C37/14
Filed: 1994-04-05
Abstract: Fire extinguishing sprinkler apparatus comprises a frame for connection to a source of fire extinguishing fluid and having a passage through which such fluid may flow along a path.  The passage normally is sealed by a closure in contact with the fluid.  The closure is maintained in its passage sealing position by a springy retainer which is held by a thermally sensitive collapsible strut in such position as to bear upon the closure.  When ambient temperature rises to a predetermined level, the strut collapses enabling automatic expulsion of the closure from the passage and flow of fire extinguishing fluid through the passage.  The closure is formed from material of poor thermal conductivity thereby preventing cooling of the collapsible strut by the transfer of heat from the strut through the closure to the fire extinguishing fluid in the passage.
