Granted: 1981-10-13
Abstract: ABSTRACT OF THE DISCLOSURE:         The invention relates to a portable grill for firing with preferably solid fuel, e.g. charcoal or the like.  The grill comprises a furnace, defined by a rectangular bottom wall, two end walls and two side walls, and a support for a grill grating or the like are arranged above the furnace.  The object of the invention is to provide a grill requiring very small storage space and being simple to get ready for use.  This is achieved in that the bottom wall of the furnace is pivotally connected to each end wall by at least two pivots for pivotal movement around a line that is parallel to and situated adjacent the edge of the bottom wall facing the end wall, and in that each side wall is pivotally connected to each end wall by a pivot which permits turning movement both around a line con-necting the pivots at both ends of the side wall and around a line that is parallel to and situated adjacent the edge of the side wall facing the end wall, so that the grill, after turning of the side walls to positions where they are parallel to the bottom wall, is collapsible to a substantially flat condition.

Abstract: ADJUSTABLE CONDITIONING PLATE FOR  AN IMPELLER MOWER-CONDITIONER              Abstract of the Disclosure A tractor drawn and powered impeller mower-conditioner includes a transverse disk type cutter bar.  An impeller rotor with free swinging flails is mounted above and slightly to the rear of the cutter bar with its axis of rotation parallel to the cutter bar.  A transversely extending concave conditioning plate conforms closely to the forward upper quadrant of the rotor.  A hood covers the rotor and conditioning plate and includes a forward portion which serves in part as safety shielding and a rearwardly extending crop deflecting and windrow forming portion.          The rotor is disposed and rotated so that the flails intercept cut material delivered rearwardly by the cutter bar and carry it inside the hood up and over the rotor through the confined space or conditioning zone between the rotor flails and the condition-ing plate and discharge it rearwardly.  In its passage through the conditioning zone, the crop material is bruised or conditioned in such a way that its rate of drying in the windrow is accelerated.          The conditioning plate is mounted so that radial clearance between it and the rotor flails can be adjusted to vary the degree of conditioning.  Circumferential adjustment of the plate in relation to the rotor is also possible and particularly useful in setting the height above the ground of the leading or lower edge of the conditioning plate to suit the height of the crop being cut and conditioned.

The bed is preferably a floating plate construction of heat insulating material.  Preferably at least part of the upper side of the bed is arranged to absorb solar radiation, which energy is transferred to the mass by washing the bed surface with water from the mass or from another source.  When used on water or watery ground, the bed may provide a support for, e.g., plantations, grounds for ball sports, etc.

Abstract: ABSTRACT OF DISCLOSURE         Methods and apparatus described maximize, within a predetermined   frequency   band,    the   continuous or near-continuous transmission  of broadband  acoustic power into a  medium having  a finite  tensile strength  such as water or earth.  Such methods and apparatus also minimize, for  a given  broadband acoustic  power level  in a  given frequency band,  the negative  dynamic pressure  or stress excursion  of  an  acoustic signal  with  respect  to  the average pressure or  stress present in the  absence of the signal.  Such  signals may be transmitted  for geophysical exploration  purposes.   The  signals   place  the  medium alternately under  compressive and  tensile stresses  with respect to some average stress, where the time duration of the  application  of  the   compressive  stress  is  short compared with the time duration  of the application of the tensile stress.   The tensile stress  does not  exceed the tensile  strength   of  the  medium  or   its  interfaces. Preferably, the  minimum time duration of  the compressive stress  is  in excess  of  one-half  period of  the  upper frequency  limit  of  the desired  spectral  band  of  the signal, while  the maximum time  duration of  a contiguous tensile and  compressive stress pair is  approximately one period of the  desired lower frequency limit  of the band. The tensile  stress waveform is preferably  rectangular in shape.

Title: Measuring device for transmitting  measuring signals via an optical link
Inventor: ADOLFSSON MORGAN
IPC: H04B10/00
Filed: 1979-09-20
Granted: 1982-07-20
Abstract: Abstract A measuring device has a transmitter side that is connected to a receiver side over an optical transmission link.  The transmitter side receives an input measurement signal from a transducer and applies the input signal to an adder that also receives a feedback signal from the receiver side.  The adder generates a comparison signal that corresponds to the differ-ence between the input signal and the feedback signal.  The comparison signal is applied to a regulator on the receiver side.  The regulator generates the feedback signal  and an output signal having a magnitude corresponding to the magni-tude of the input signal.  Amplification of the feedback sig-nal on the receiver side is controlled by time division or frequency division calibration signals, so that the total amplification of the feedback signal between the adder and the regulator is held constant.

Abstract: Abstract of the Disclosure A body support member for spacing a body above a supporting structure which comprises a sheet of resilient plastic material permanently deformed to produce downwardly disposed, laterally spaced, elongated protuberances distrib-uted over a body support area for engaging the supporting surface, adjacent elongated protuberances being complementary in shape with each one having a plurality of reversed direc-tion portions along its length, the reversed direction por-tions in adjacent protuberances being in overlapping relation in the plane of the body support area looking in the direc-tion the elongated protuberances extend, whereby the body support area of the member will resist flexing along all lines traversing the body support area.  Where desired, the resiliency of the plastic material of the body support member can be such that the reversed direction portions of the elon-gated protuberances incorporate an inherent spring-like action under the weight of a supported body to cushion the same.
