Patent BE-765280-A (BE)
Title: Holder for insecticide
IPC: A01M1/20
Filed: 1971-04-05
Abstract: A holder for a tablet of solid insecticide consists of a flat plastics box. The insecticide tablet is contained in a sheath of plastics material inside the box. The plastics sheath is impermeable to the vapour of the insecticide. On removing the plastics sheath the insecticide slowly vaporises. During transit the insecticide cannot contact the holder and so no risk of the user touching the insecticide occurs. The insecticide may be e.g. dimethyldichlorovinyl phosphate.

Title: Barley preparation and pulverizing plant - for brewing mash
Inventor: BROLL A
IPC: C12C7/00
Filed: 1972-08-24
Abstract: The barley is delivered to the brewery, or is taken from storage silos, in the grossly contaminated state with a moisture content of approx 12-14%. It is first dry cleaned e.g. by air sitfting and is then moistened to approx 18% over a period of 25-30 mins. whilst simultaneously it is washed intensively. After draining the washing water it is flash steamed e.g. at 100 degrees C with saturated steam at normal pressure for 0.5-1 min. The moisture level then rising to approx 25%. It is then steeped in cold water (10-15 degrees C) to raise the moisture level to approx 30% after which it is again drained and then fed to the wet bruising machine in which the glume is split longways and separated from the corn by tearing off.

Abstract: ABSTRACT OF THE DISCLOSURE      A normally rigid plastic pipe is shaped by softening a selected zone of the pipe, inserting into the softened zone a resiliently deform-able mandrel and pressing axially on opposite sides of the mandrel. This expands the mandrel radially into frictional engagement with the softened pipe zone. Simultaneously the mandrel is shortened axially, thereby correspondingly expanding radially and shortening axially the softened portion of the pipe while proportionately thickening its side walls.

Abstract: TITLE OF THE INVENTION:            DISCHARGE LAMP LIGHTING DEVICE USING A BACKSWING BOOSTER            ABSTRACT OF THE DISCLOSURE:            A discharge lamp lighting device combines one or more dis-charge lamps and a backswing booster including essentially a power source circuit having a power source connected in series with a ballast and a high voltage generating circuit having an oscillation capacitor and a series circuit of a nonlinear inductor and a switching semiconductor.  The supply voltage for the discharge lamp from the power source circuit is established to the extent permissible by the lower limit for sustaining an arc discharge of the lamp so that the ter-minal voltage of the ballast in the lamp operation is main-tained as low as possible.  The preferred backswing booster is of small size and an impedance circuit having a capacitor either with or without a bias coil is added to the high voltage generating circuit to produce a momentary high voltage.          A leakage transformer or a voltage transformer with a tap or with a supplemental winding may be coupled to the power source circuit to establish a specified potential point from which voltage for the high voltage generating circuit is supplied to reduce the applied voltage during the lamp operation.  An economical lighting device for the sequential ignition of two discharge lamps by means of a single high voltage generating circuit is disclosed.

Abstract: ABSTRACT   A device is disclosed which converts a digital signal or bit stream into a digital signature representative of the digital signal by means of a feedback shift register.  The apparatus may be used to identify and characterize digital signals at various test points in an apparatus for testing purposes.  Signatures for digital signals from properly operating circuits can be re-corded in a variety of fashions for later comparison with signa-tures of digital signals from circuits under test.  The compari-son of the signatures enables a person using the apparatus to determine whether the circuit under test is operating properly and, if it is not, to locate the fault in many instances.  The apparatus may also be used to examine repetitive digital signals to enable identification of transient errors.

Abstract: Abstract of the Disclosure Disclosed is apparatus which provides a warning or "brownout" signal which indicates a likelihood of low power in an AC wave.  This condition  is measured by analysis of the peak voltage attained by each half cycle.  Every power supply is designed for an AC supply having a nominal peak voltage. Defective or "runt" half cycles are those whose peak is less than a predeter-mined percentage of nominal peak voltage.  In this invention, each low voltage or runt half cycle causes the contents of a counter to be changed by a pre-determined value.  A preferred level for the peak voltage of any half cycle, below which the half cycle is classified as a runt is 90% of nominal.  Each time the maximum voltage of a half cycle equals or exceeds the predetermined percentage of nominal, the counter contents are changed by A second predator mined value in the opposite direction unless the excess of good over runt half cycles is so great that the counter has reached a third predetermined value, If the count maintained in the counter ever reaches a fourth predetermined value because of a large number of runt half cycles, a brownout signal is issued,  By proper choice of the first through fourth predetermined values, this apparatus can be made more or less sensitive to runt half cycles.

A monitor unit is connected to all of the units to receive signals indicating the operational states of the units.  Each unit may include a watch-dog timer having a counter which is regularly incremented and periodically reset to zero in response to a software instruction so that if a central processing unit gets into a software loop the counter exceeds a threshold value and produces a signal indicating the presence of such a loop.  The watch-dog timer may be used to reset the central processing unit to a datum position, erasing all data recorded up to the time as a result of programme execution.  A diagnostic unit may be provided enabling an engineer to try out test routines on the units to ensure their correct functioning.
