Title: Lights for vehicles
Inventor: DASHWOOD NIGEL J R
IPC: F21V7/00
Filed: 1987-05-11
Granted: 1991-08-27
Abstract: IMPROVEMENTS IN LIGHTS FOR VEHICLES          ABSTRACT OF THE DISCLOSURE          A  vehicle  lamp for bicycles and the like is  provided, having a compound reflector.  The front opening is  non-circular in shape,  generally rectangular. The reflector itself  has  a  plurality of nested  sections  that are stepped  one  from another,  each lying on a surface  of revolution  generated  by a  different  curve  extending rearwardly  from the front,  each curve being  generated from  a common generating point in the vicinity of which an  intended  light source is to be  held.  One  of  the sections  is  defined by an empirically determined  non-conic curve, and has a characteristic angularly unbroken reflected  beam from a point source,  which diverges  in the far field but with a pattern of angular spread where intensity falls relatively sharply from the beam centre, so  as to provide a central pool of light of  relatively high  intensity  and  an extended relatively  low  level intensity  on  either  side.   The  other  sections  are similarly  formed,   but  have  another  characteristic angularly  unbroken  reflected beam from a point  source which  diverges in the far field but with a  pattern  of angular  spread where intensity falls relatively  slowly from the beam centre.

Title: Rock anchor
Inventor: GRUBER HEINZ
IPC: E21D20/02
Filed: 1987-09-09
Granted: 1992-02-04
Abstract: ABSTRACT    A rock anchor consists of a body member formed as a drilling rod, which at one end carries a drill-head and has externally over its whole length a coarse thread, for example an approximately round thread.  The drill-head is welded to the drilling-rod.  The drilling-rod has only at its forward region, that is adjacent the drill-head peripheral bores, whereby the aforesaid forward region, from the drill-head, extend over a length of at most 20 cm.  The bores extend as an angle to the axis of the drilling rod, namely, from inside to outside in a direction from the drill-head.  This rock anchor serves simultaneously for making a drilling, whereby the tubular body member serves for the supply of the hydraulic fluid, which passes into the bore-hole via an hydraulic bore in the drill-head and the aforesaid peripheral bores and passes back to the outside of the drilling rod with the drilling lines produced.  After completion of the drilling a mortar suspension under pressure is injected via the aforementioned body member, which likewise flows via the bores, so that the borehole is gradually filled with the mortar base of the borehole.  The rock anchor according to the invention has considerable structural simplicity and likewise is simple to handle, so that broken rock can readily be stabilised by means of it.

Title: Digital measuring instrument
Inventor: BRAND KLAUS-PETER
IPC: G01R19/02
Filed: 1987-10-27
Granted: 1991-06-25
Abstract: ABSTRACT     The digital measuring instrument samples at dis-crete points in time the analog output signals emitted by a measurement transducer (2) of an electrical supply sys-tem in a sample and hold circuit (4), subsequently digi-tizes the sampled values in an analog/digital converter (5) and then forms a system-specific quantity such as, for example, the root mean square value or the system frequen-cy from the digitized values in a digital processing unit (6).     This measuring instrument is intended to be suit-able for solving the essential measurement value process-ing tasks occurring in an electrical supply system in a simple manner and with projectable measurement accuracy.        This is achieved by the fact that the digital pro-cessing unit (6) exhibits a block (7) for shifting the frequencies (.omega.1, .omega.i) of fundamental and harmonics to 3 direct-current signal (DC) which is proportional to the system-specific quantity and a subsequent filter arrange-ment (8) with a digital low-pass filter (100) for suppres-sing the frequencies (.omega.1, .omega.i) deviating from the direct-current signal (DC) and a digital band-stop filter (110) for suppressing aliasing frequencies.

Patent CA-1304143-C (CA)
Title: Electronic thermostat employing adaptive cycling
Inventor: BERKELEY ARNOLD D
IPC: F23N5/20
Filed: 1987-12-08
Granted: 1992-06-23
Abstract: ABSTRACT  Environmental heating/cooling systems are controlled by an interactive microprocessor and have continuous on-time and adaptive cycling modes wherein continuous on-time brings the temperature to a programmed set point and cycling precisely maintains  that  temperature  rather  than  causing  the temperature  to  oscillate  between  limits  of  a  dead  zone.          Minimum pause and on-time intervals of the cycling mode are established  in  accordance  with  optimum  thermal  transfer efficiency and/or equipment limitations.   The initial cycle pause interval is a function of the degree transition time (i.e.,  time required for system to change temperature one degree  as  measured  during  continuous  on-time  mode);  the initial  cycle  on-time  interval  becomes  the  established minimum interval.  Cycle intervals are modified as necessary to maintain the temperature at the set point with preference given to minimizing the cycle on-time interval.  Hence, the cycle  on-time  interval  is  decreased  to  its  established minimum  before  attempting to  increase  the  cycle  pause interval; conversely, the pause interval is decreased to its established  minimum  before  increasing  the  cycle  on-time interval.  The system is predisposed to remain in the cycling mode whereby predetermined temperature variations from set point, in a direction opposed to system control, initiate a continuous on-time to bring the temperature back to set point,  but only after attempting to do so with an additional  modified  cycle.    Degree  transition  time  and initial pause and on-time intervals are re-established during each  continuous  on-time  mode.    Cost  savings  provided  by cycling, as compared to continuous on-time, are periodically computed.

Title: Bioerodable implant composition
Inventor: GERHART TOBIN N
IPC: A61L24/00
Filed: 1988-03-11
Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE       An improved bone cement is comprised of a particulate biocompatible calcium phosphate ceramic and particulate resorbable calcium salt dispersed in a cross-linked biodegradable polyester matrix.  The polymer/salt-particle composite exhibits good biomechanical strength/modules characteristics with surgically acceptable cure times.  When used for sustained release of biologically active agents in a physiological environment, controlled release of biological agents that are mixed into the composite can be achieved as the cement biodegrades.  When used for bone/implant fixation, or as a filler or cement for bone repair, gradual biodegradation of the cement composite permits, under suitable circumstances, eventual replacement of the cement with developing bone tissue.

Title: Technique for roll stabilization and partitioning of phased array antenna receiving apertures
Inventor: VODOPIA SAMUEL N
IPC: H01Q1/18
Filed: 1988-04-26
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE An active array system is disclosed with electronic roll stabilization of the difference patterns, and with arbitrary partitioning of the phase scanned aperture with no hardware changes.  The array system comprises a large number  of  radiating  elements  forming  the array,  with individual transmit/receive active modules coupled to each radiating element.   In each active module, the received signal is amplified and then divided into three signal components.   Two  of  the  signal  components  are  passed through a bi-state phase  shifter for selectively phase shifting the signal component by 0 to 180 degrees.  The selectively phase shifted receive signals are then coupled to the respective azimuth and elevation difference chan-nels.  The third signal component is coupled to the sum channel  network.   The  respective  sum  and  difference channels all provide summing functions on the respective sum and difference signals from each module.  The phase shifters provide an output signal with either a positive or negative sign, so that in effect the module signals are "differenced" first and then summed.
