Abstract: Abstract A passive radar target comprises a solid lens (50) of substantially uniform dielectric constant, having a reflecting surface (51) integrally formed therewith, the lens being constructed of particulate material having a dielectric constant selected such that radar waves striking the surface of the lens are focussed on the reflecting surfac.e  In one form the particulate material comprises silica flour (91,101) contained within a thin radar transparant polycarbonate shell.  The shell is formed of two similar halves (102,103) with a pressed aluminium reflective lining (92)106) in one half.  By making the lens axially symmetrical such that the forward and rearward surfaces have a radius of curvature that decreases with distance from the transmitter.  Two such lens-reflectors back-to-back will provide substantially omnidirectional operation.  In an alternative arrangement back-to-back concave reflecting surfaces (114,115) are centrally located within a single spherical shell (117) filled with particulate material (116).      In some applications a particulate filler such as powdered slate is held by means of a polyurethane foam.

Title: Optimized nutrient conditions for producing microorganism secondary metabolites
Inventor: MARSHALL J WAYNE
IPC: C12N1/14
Filed: 1987-12-01
Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE      A process for increasing the production of secondary metabolites during culture of a selected fungi comprises a pulse feeding technique to enhance continued production of the desired secondary metabolites.  The selected fungi is cultured in an initiating media containing assimilable sources of carbon, nitrogen and phosphates.  The fungi is cultured in the media through its growth phases to produce the secondary metabolites.  The culture is pulse fed during secondary metabolite production by periodically supplementing the media with an additional source of carbon.  Such pulse feeding has resulted in a significant production of secondary metabolites, whereas in normal culture feeding programs the production of secondary metabolites tends to fall off after a certain length of time.

Abstract: ABSTRACT OF THE DISCLOSURE         The  vehicle  is  more  particularly  a  bicycle  which comprises a frame carrying at its rear end a wheel  actuated by a pedal mechanism while the front end carries a collar.  A brace is pivoted to the frame in the region of the pedal  mechanism and so is a  saddle post.   The  front end  of the  brace also carries a collar, both collars are slideable along an upright stem carrying the  handle  bars  at  the  upper  end and the front wheel of the bicycle at its lower  end.   A latch  releasably holds  the frame collar on  the lower  end of  the stem  while a cable attached at both ends  to the  handle bar  and to  the brace  collar and also attached to  the brace collar serves to maintain the latter in an intermediate position along  the  stem,  whereby  the  brace, the front portion of the frame and the lower part of the stem forms a triangle holding the bicycle in erected  position.   A releasable stay rod  pivotally connected  to the  saddle post and releasably latched to the rear portion of the frame, maintains the saddle in erected position.   To collapse the bicycle, it is only necessary to unlatch the lower  collar and  to pull  on the  cable to slide both collars upwardly along the stem causing rotation of the stem towards the underside of the frame with the front wheel  taking a position overlapping  the front wheel.  The saddle post is folded over the frame.

Title: Chlorine oxidation waste water treatment method
Inventor: SAYLOR WILLIAM D
IPC: C02F1/76
Filed: 1988-07-14
Granted: 1992-03-31
Abstract: CHLORINE OXIDATION WASTE WATER TREATMENT METHOD                 ABSTRACT OF THE DISCLOSURE   A method for oxidation treatment of waste water material containing organic solid particles includes forming a discrete batch of waste water material, adjusting the pH of the entire batch to close to 7 or acid-alkaline neutral, and then flowing the batch through a reactor along with chlorine gas. The chlorine produces hypochlorous acid, which produces nascent oxygen and hypochlorite ions, for chemically oxidizing the organic solid particles and also forming minute gas bubbles, including nitrogen and carbon dioxide, which adhere to the particles. The treated material is flowed into a separation receptacle, where the gas bubble buoyed particles float to the surface of the water, The clear water is rapidly gravity-drained from beneath the particles, leaving the particles coalesced into a relatively dry, disinfected or stabilized sludge. The drained clear water may be substantially pH-neutralized and then flowed into a water system for reuse, while the stabilized, disinfected sludge may be deposited elsewhere as fertilizer or ground cover and the like.

IPC: B27K3/08
Filed: 1988-07-19
Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE         A new method for the impregnation of porous materials by solutions, especially solutions which impart desirable physical, electrical, chemical and other properties to the porous material, is disclosed.          Microwave energy inductively heats the liquid moisture contained within the porous material for a prescribed time, in such a manner so as to rapidly convert the liquid moisture in the inner portion of the porous material to gaseous moisture.  The gaseous moisture drives the remaining liquid moisture to the surface of the porous material.  The porous material is quickly cooled and the desired solution applied to the surface of the porous material immersing or coating.  The gaseous moisture contained in the outer portion of the porous material condenses to liquid moisture thereby creating a relative vacuum which induces the solution to impregnate the porous material.
