Title: Method for the production of tablets of soap
Inventor: VAN BUUREN CORNELIS
IPC: C11D13/16
Filed: 1989-10-27
Abstract: ABSTRACT            A  method for the production of tablets of soap, said tablets of soap being made up of several layers of soap, in a mould. This mould comprises two or more parts with a filling aperture. The mould is filled with a soap which is liquid above a specific temperature which is above 40 degrees Celsius, and which is solid below a temperature which lies below the afore-mentioned specific temperature; before the parts are combined to form the mould, one or more parts of the mould are filled with a layer of soap at a temperature at which the soap is liquid. This soap layer is then cooled to a temperature, following which the mould is closed and the remaining space is filled up with a soap whose temperature is above the melting point of said soap, each soap filling having a desired composition. The preference is an object, such as an illustration, a free gift article, a logo or the like, is placed on the last layer of soap formed, after one or more layers is placed in one of the mould parts and cooled to a desired temperature, and before the mould parts are combined and the remaining space filed up with soap.

Abstract: A  manually operable  switch  apparatus for  a machine having at  least one mode of operation actuated by a control circuit includes a spaced pair of switches which are simultaneously  manually operable without the application  of   exertive  contact  by   an  operator.          Preferably,  each switch  includes an  infrared emitter spaced  from  an infrared  receiver,  and  a single  or double pole, double  throw relay actuated when the beam between the emitter  and receivers are broken, so as to cause  actuation  of  an  alternative mode  of  machine operation.   The use of  switches which do  not require exertive  contact  obviates  the  injury to  wrist  and finger  tendons experienced  by machine  operators when conventional  palm  buttons  are employed  on  machines requiring repetitive  operator manipulations.   The use of  a spaced  pair of such  switches requires  that the operator place  both hands on the  switches in order to operate  the  machine,  so  that  the  operator  cannot inadvertently  place  a  hand  in  or adjacent  to  the machine  during  operation,  thus  serving  to  prevent injury  to the  worker.   Such  a  switch apparatus  is substantially    more   reliable    than   conventional mechanical   and   pneumatic   switches,   subject   to significantly less breakdown in use.

Title: Food service system
Inventor: WOOD SIMON J
IPC: H05B3/68
Filed: 1989-11-24
Abstract: ABSTRACT                      FOOD SERVICE SYSTEM      In a food service system, prepared meals including chilled foods are assembled in individual meal trays (10) and held in the trays for a period prior to regeneration to prepare the food for heating.  A control system of a rethermalizing trolley (12), which accommodates a large number of trays, can discern for itself which dishes (30) in the trays need heating and which are to remain cool.  Dishes for hot and cold foods have white and black markings respectively, which results in reflected infra -red signals from sensors (42, 44) of the control system to be of discernably different strengths, so identifying the hot sensors dishes.  Dish temperature is continually monitored by the control system by means of thermal contact with thermistors (46), which enables the system to oversee food temperatures both prior to and during regeneration.

Title: Digital transmission system
Inventor: TAKASAKI YOSHITAKA
IPC: H04L25/49
Filed: 1989-12-18
Abstract: ABSTRACT        Data transmission and recovery, in either the optical or the electrical domain, can be accomplished with mBnB encoding with the violation of one or more of the n code pulses for multiplexing overhead signals, with a carried clock being indicated by periodic fixed position transitions, and with both extraction of the clock and demultiplexing of the overhead signals being accomplished with only logical processing and signal delay. For the above, transmission and processing in only the optical domain can be easily obtained as well as a circuitry that can be constructed cheaply and on a small scale, particularly by integration on a single substrate. The logical processing involves logical combinations of two or more of the received encoded signal, a delay of the received encoded signal, an output of a previous logical combination, and a delayed output of a previous combination, an extracted clock, and a frequency division or a frequency multiplication of an extracted clock.

Abstract: ABSTRACT OF THE DISCLOSURE:            A quadrant driver is disclosed,  for use to drive the rotor of a microwave switch at 90° from one given input-output configuration  to another given input-output configuration and vice verse.  The driver comprises a magnet and bearing holder rotatably mounted inside a housing.   The holder supports, on one side, a thin, high magnetic density magnet and,  on the other side, a bearing operatively connected to the rotor of the microwave switch to rotate this rotor when the holder is itself rotated,  the holder and magnet being rotated between two rest positions,  each of the rest positions corresponding to one of the two configurations of the microwave switch.   A pair of coils are mounted concentric to mild steel cores  mounted within the housing so that one of the cores faces with a given offset the magnet when the magnet is in one of its rest positions and the other core faces with a given offset the magnet when this magnet is in the other of its rest positions.  A power source is used to selectively energize each of the coils to cause rotation of the magnet and associated holder from one of its rest position to the other, and vice versa, whenever desired.  The advantages of using the quadrant driver are : size reduction, weight reduction, production cost reduction, maintenance cost reduction,  easily adjustable to different driving voltages.

Title: Water-cut monitoring means and method

IPC: E21B47/10
Filed: 1990-07-05
Abstract: WATER-CUT MONITORING MEANS AND METHOD                       (D#79,154-F) ABSTRACT OF THE DISCLOSURE           Oil well production is often measured by using a settling tank, pump, flowmeter and a water-cut meter.   Fluid from a well  being tested  is allowed to  accumulate  in  the settling tank and,  after a predetermined settling time,  is pumped through the flowmeter and water-cut meter for gauging. The present invention is an improved water-cut meter which first determines the impedance of the free water pumped from the tank and later determines the impedance of the oil/water emulsion emerging from the tank.  The ratio of the emulsion impedance  to  the  free  water  impedance  is  proportional  to percent water-cut  of the  fluid during the water-continuous phase.  When the emulsion switches to oil-continuous phase, the system  utilizes   probe   impedance   for   the   water cut determination.  Using standard techniques,  the water-cut and flow rate signals are then combined to calculate the total oil and water content of the settling tank fluid.
