Patent DE-3278985-D1 (DE)
Title: Waste receptacles having odor barriers
Inventor: LANDER HARRY L
IPC: B65D90/42
Filed: 1982-07-13
Granted: 1988-10-13
Abstract: Waste receptacles for use by animals, such as laboratory animals and household pets, are provided with an odor barrier of lightweight, non-absorbent, non-water-wettable, granular material, such as paraffin wax coated corn cob granules. The buoyant, non-absorbent, lightweight granular material is also useful as an odor barrier in liquid-containing portable human toilets and generally as an odor barrier for pools or sumps or open containers of odoriferous materials, such as aqueous offal wastes, aqueous waste from food processing plants and odoriferous wastes from other sources, such as industial sources, e.g., paper mills, chemical plants, manufacturing plants and the like. The non-absorbent granular material in animal toilet applications is conveniently retained on a foraminous tray which, in turn, is mounted on a collecting tray for collection of liquid waste percolating downwardly from the granular material into which the liquid waste was originally deposited.

Title: Method and apparatus for compressing gas
Inventor: ALLAM RODNEY JOHN
IPC: F01K27/02
Filed: 1982-05-25
Granted: 1988-12-15
Abstract: The fuel required to provide the energy for compressing a gas can be reduced by compressing the gas substantially adiabatically through a pressure ratio of at least 2.5:1 in a compressor, cooling the hot compressed gas by heat exchange with water at superatmospheric pressure, further heating the water to produce super-heated steam and using the superheated steam to drive the compressor. The total amount of fuel consumed can be considerably less than that used for compressing gas conventionally (i.e. substantially isothermally).

Abstract: @ A pair of small diameter optical fibers (12, 14) are arranged in a side-by-side configuration, the first fiber (12) providing a passive guide for pump light, and the second fiber (14) formed of a material, such as Nd:YAG which has amplifying properties at the signal frequency. The signal to be amplified propagates through the second fiber (14) resulting in amplification of the signal. The first fiber (12) is pumped from one or both ends, utilizing a cone shaped rod (50) which is optically coupled thereto. A plurality of pump light sources (60) are mounted on the end face (58) of the rod (50) to introduce collimated pump light into the large end (52) of the cone shaped rod (50). Total internal reflections on the cone walls compress the pump light to a small, fiber-size diameter end (54) for propagation through the pump fiber (12) and absorption by the active fiber (14). The pump light sources (60) are offset from the axis (72) of the rod (50) to excite high order modes in the pump fiber (12) to enhance absorption by the active fiber (14). The pump light sources (60) preferably comprise high power laser diodes (64) and collimating microlenses (62). By utilizing the cone-shaped rod (50) to couple light from the high power laser diodes (64) to the pump fiber (12), high pump power densities can be achieved, yielding increased amplification.

Abstract: Microinjection techniques for plant protoplasts utilize a holding pipette for immobilizing the protoplast while an injection pipette is utilized to inject the macromolecule. In order to manipulate the protoplasts without damage, the protoplasts are cultured for from about 1 to 5 days before the injection is performed to allow for partial regeneration of the cell wall. It was found that injection through the partially regenerated cell wall could still be accomplished and particular compartments of the cell could be targeted. The methods are particularly useful for transformation of plant protoplasts with exogenous genes.

Abstract: The specification relates to an apparatus intended for panoramic X-ray photography of the area of the dentition and the jaws, the apparatus comprising a frame (1), a bearing part (2) which is linearly movable in relation to the frame part, and a support arm (10) which has been attached by means of bearings rotatably to the bearing part and which has at one end an X-ray film (11) and at the opposite end a source of X-radiation (12). The movements of the bearing part (2), the support arm (10) and the film (11) are mutually synchronized in such a way that an image of an area of the desired shape, for example an area the shape of the patient's dental arch, is obtained on the film during the movement. It is the object of the invention to provide the effect that the X-ray beam can be tilted to the desired angle in relation to the horizontal plane, whereby it is possible with greater sharpness than previously to photograph, for example, teeth slanted in relation to the vertical plane. In accordance with the invention, the support arm (10) is attached with bearings to the bearing part (2) so as to be tiltable about an axis perpendicular to the rotational axis of the support arm so that, when the rotational axis is vertical the straight line connecting the source of radiation (12) and the film (11) is oblique to the horizontal level.

Abstract: To assist with correct demodulation of a radio data signal (RDS) it is sampled four times. The sampling intervals are determined by a square wave synchronised with the RDS signal. The samples are each phase shifted by a quarter period, and the first sample lies at a zero in the RDS signal. Successive even numbered samples are compared with each other. If there is inequality then the intermediate odd numbered sample is used to check for parity. The results of the test, depending upon the parity check, are added or subtracted to obtain a synchronising signal for the square wave. If the even samples are the same they are then tested to determine if the samples belong to the same sample cycle or to a different one. If this identity check gives an accumulated result greater than a set value then the square wave is shifted by 180 degrees. The data in the RDS signal is recovered from the even numbered samples.
