Abstract: ABSTRACT:         "Method and apparatus for compensation during ultrasound examination".     The time-gain function of an ultrasound receiver for medical examinations is modified to compensate for different attenuation characteristics in body structures. The slope of the time-gain function is increased at times associated with pulse transmission through the highly attenuating body wall and may be decreased at times associated with pulse transmission through fluid filled body structures. The time-gain compensation, in combination with probe focus compensation and a highly linear receiver transfer function provides sharply in-creased diagnostic quality. The location and attenuating characteristics of body structures may be determined from distinctive signatures in ultrasound echos.

Abstract: ABSTRACT OF THE DISCLOSURE          A method is provided for obtaining liquid hydrocarbons in a destructive distillation process.  The method includes the step of first pulverizing media, which contain liquid and solid carbon-hydrogen-contain-ing substances, to particle sizes of less than 10 mm.  The pulverized media are then thermally treated to produce a flue stream of hydrocarbon vapors.  Vaporization materials in the flue stream thereof are at least partially rapidly vaporized to generate a product flow and the entire process heat necessary for such thermal treatment step.  The process heat is supplied directly with the product flow to the thermal treatment step.          Finally, hydrocarbon vapors are condensed to form liquid hydrocarbons.

Abstract: D 8138-real TO ALL WHOM IT MAY CONCERN      BE IT KNOWN THAT WE, Wolfgang Pozsicsanyi, residing at Sudetenweg 58, 7170 Schwabisch Hall, Friedrich Koger, residing at Fichtenstrasse 4, 7113 Neuen-stein, and Heinz Wieland, residing at M?rikestrasse 2, 7112 Waldenburg, of German nationality, have invented certain new and useful improvements in --An apparatus for causing flow of a fluid--of which the following is a specification:-Abstract An apparatus for causing the transport of a fluid, that is to say a liquid or gas, has a housing for guiding the fluid and a motor-powered bladed wheel for producing a flow of the fluid through the housing. The bladed wheel is made up of a shaft or ot-her part with the function of a shaft and a number of blades pla-ced one after the other in the direction of turning and stret-ching radially outwards on the one hand and along the axial length on the other hand. The volume flow of the fluid moving through the housing of the apparatus is separated by a separating mem-brane, placed within the bladed wheel, into an incoming fluid flow, for example incoming air or air from the atmosphere, and and outgoing fluid flow, for example of waste air. A number of heat pipes or heat pipe-like rods are fixed in relation to the housing so as to be normal to the fluid flow. These heat pipes are generally parallel to the length direction of the blades so that the one axial end of each heat pipe or the like is acted upon by the incoming fluid flow, for example air from the outside while the other axial end part is acted upon by the outgoing fluid flow, for example waste air.

Abstract: Elevator Cab Load Measuring System Abstract Transducers are located between the elevator cab and the supporting frame at points which lie along a line that passes through the cab center of deflection.  These transducers produce an analog output whose magnitude varies proportionally with the force applied through the transducer to the cab.  The outputs of the transducers are summed together and the actual sum corresponding to the empty car condition is subtracted from the sum of the outputs and the remainder is multiplied by the actual ratio between car weight and the sum of the transducer outputs.  This yields the cab load.

Abstract: RINGING SIGNAL SUPPLY     Abstract of the Disclosure A ringing signal supply, provided at a concentrator remote from a switching office, compares a fraction of its output with a low level reference ringing signal supplied from the switching office to produce an error signal.  The error signal, if it exceeds a positive or negative threshold, is gated during respective half-cycles of a rectangular alternating voltage produced by an inverter to control a bidirectional switch to connect the inverter output to the input of a low pass filter, whose output constitutes the output ringing signal.  In this manner the instantaneous voltage of the output ringing signal is modified to reduce the error signal, whereby the output ringing signal has the same frequency and waveform as the reference ringing signal.

The combination comprises a holster having inner and outer side panels which assist in forming a tapering configuration for conformably receiving a hand gun.  The holster has an open end for insertion and withdrawal therethrough of the gun.  The belt is attached to the inner side panel of the holster and suspends the holster on one side of the waist of a person. A retaining member is provided having first and second ends. The member is attached at the first end to the outer side panel of the open end of the holster.  A means is provided for detachably mounting the second end of the retaining member to the belt.  Thus when the retaining member is mounted to the belt the hand gun is safely retained in the holster and cannot be withdrawn therefrom.  A release means is provided which is attached to the belt for automatically detaching the retaining member from the belt.  The release means is adapted to be activated by the hand opposite the side from which the holster is suspended.  Thus when the retaining member is released from the belt the gun can be withdrawn from the holster.  Such a combination holster and belt prevents the accidental removal of the gun from the holster, e.g., in a chase, etc., or the removal of the gun from the holster by a person other than the person wearing the holster.
