Abstract: "LIQUID FILTER" ABSTRACT OF THE DISCLOSURE         Filters, particularly relative small filters, usually include a screening element which readily clogs or becomes partially blocked with material thus impeding the flow of liquid therethrough.  The present invention com-prises a cylindrical filter housing or bowl portion bisect-ed by a vertically situated screen element situated at an angle to the direction of flow so that the flow of fluid tends to wash the screen and deposit the sediment at the base of the housing.  Preferably the housing is formed of clear plastic or glass so that the screen condition can be viewed.  The base of the screen element is angulated and lies on the base of the housing upon the inlet side there-of so that when removing the screen for cleaning, any sedi-ment may be lifted clear of the housing as the screen is re-moved.

Abstract: ABSTRACT OF THE DISCLOSURE                 An omnidirectional acoustic sensor has an air-backed diaphragm in a unit which has a central axis and is mounted so as to be responsive to acoustic pressure waves.  A piezoelectric ceramic disc is attached to each face of the diaphragm.  This combination forms a sensor unit whose acoustical and capacitive sensitivities are relatively independent of varying static pressure.  The ceramic discs and diaphragm are each of a preselected size such that the ratio of disc diameter to diaphragm diameter is not greater than about 0.8.  The sensor assembly further includes collar-like support means from which the diaphragm is supported.  The sensor unit has a radius of zero stress, with the diaphragm being connected to the support means radially outwardly of the radius of zero stress.  The ceramic discs lie within that radius of zero stress.          In the preferred configuration the diaphragm and support means are the same piece of material.  A sensor assembly is formed by securing two sensors together, the collar-like support means being joined together by axially facing surfaces thereof.

Abstract: ABSTRACT         The present invention relates to cameras for X-ray diffraction analysis of crystalline samples to determine lattice parameters of a sample.  More particularly the invention relates to an X-ray diffraction camera having a hypocycloidal gear train adapted to cause rotation of the sample within the camera about two generally normal axes.          Prior art devices do not provide for the rotation of samples about two or more axes, therefore a preferred camera according to the invention comprises/ a sample mounting including a sample support to position the sample at a pre-determined location, means to receive and support a film, means to direct x-rays at the sample so that scattered rays leaving said sample expose the film, and drive means to rotate the sample about two generally normal axes inter-secting at that location.  The drive means includes a hypocycloidal gear train having a base gear to which the mounting is attached, the base gear being rotatable about one of the specified axes, and a planetary gear meshingly engaged with the base gear and wherein the sample support is coupled to the planetary gear so as to be rotated about the other axis.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention provides an industrial cooking machine having an endless conveyor passing through both a preheat region and a cooking region with a pair of accesses to the conveyor.  These accesses separate the preheat from the cooking region and enable loading and unloading of food onto the conveyor between the two regions.  The conveyor is reversable in direction of travel so that the food loaded at the first access can be moved in either one of two directions.          Firstly it is movable  through the preheat region past the second access to the cooking region and back to the first access and secondly when the conveyor is reversed the food which is loaded on the conveyor at the first access is movable  directly through the cooking region to the second access which is positioned to permit unloading of the food without passing through the preheat region.

Abstract: ABSTRACT      A sine wave oscillating circuit arrangement useful in generating an electromagnetic field, for example, comprises a resonant circuit including an inductor through which the current is tightly controlled and a capacitor connected in parallel, to which dc pulses are applied at a repetition rate equal to the resonant frequency.  The current flowing in the inductor is sensed in phase detector and amplitude detectors.  The results of these evaluations are applied to cascaded pulse position and pulse width and/or amplitude modulators. A current switching driver circuit driven by pulses from the modulator is connected to the resonant circuits for modifying the dc pulses applied for maintaining the sine wave current in the inductor at the proper amplitude and phase relationship and energy content inversely as the potential across the sampling resistor in the resonant circuit.  The energy dissipated in damping the resonant circuit in one cycle of operation is replaced in the next cycle.
