Abstract: SIDE INLET BALLCOCK HAVING FLOW AND STRUCTURAL IMPROVEMENTS            Abstract of the Disclosure:          A horizontal water inlet tube is inwardly connected reversely through a valve within a horizontal valve housing and from the valve housing downwardly into a generally vertical water outlet tube.  The valve is controlled by a valve control arm projecting generally horizontally from the valve housing downwardly connected through a float connector to a float vertically slideable on a float guide extending downwardly from the valve housing.  A div?ter at the upper end of the water outlet tube receives water flow generally horizontally from the valve housing into a pair of spaced, downward helical grooves dire?ing the flow spirally into a pair of spaced vertical grooves for ultimate discharge downwardly through the water outlet tube.  The diverter vertical grooves are larger in cross-section than the respective helical grooves and are formed by radial plates converging centrally to a cylinder at groove upper portions and an inverted cone at groove lower portions, each vertical groove occupying in the order of 120° of the outlet tube circumference.  For shipment, the float guide may be pivoted upwardly at its connection to the valve housing simultaneously carrying the float and float connector without disrupting assembly placing these elements approaching horizontally parallel to the inlet tube, valve housing and valve control arm.  The outlet tube is selectively disconnectable adjacent the valve housing for positioning thereof generally horizontal.

Abstract: ABSTRACT OF THE DISCLOSURE An intake port structure for an internal combustion engine having a two-barrel carburetor includes a primary intake passage defined in a cylinder head for supplying an air-fuel misture into a combustion chamber in a full range of loads, and a secondary intake passage defined in the cylinder head for sup-plying an air-fuel mixture into the combustion chamber under relatively high load conditions.  The primary intake passage has a first outlet port opening into the secondary intake pas-sage immediately upstream of the valve face of an intake valve.          The secondary intake passage has a second outlet port opening into the combustion chamber through the valve face.  A wall pro-jects into the secondary intake passage adjacent to the second outlet port for deflecting an air-fuel mixture flowing from the secondary intake passage into the combustion chamber to form a swirl of air-fuel mixture in the combustion chamber.  The air-fuel mixture flowing from the primary intake passage is guided along a side of the wall which faces upstream in the secondary intake passage, and is also guided by a groove extending from the first outlet port into the secondary intake passage.  The side of the wall and the groove assist  the air-fuel mixture flowing from the primary intake passage in forming a swirl of air-fuel mixture in the combustion chamber.

Abstract: Thermally Insulated Tank Structure And Method For Forming The Same Abstract A large volume, thermally insulated tank is formed by constructing the tank sidewall in super-imposed sections.  Each section is constructed with-out the use of external support forms by laying a first outer course of thermal insulating material and then forming a first inner course of refractory material spaced therefrom.  The cavity between the two courses is then filled with cementitious material, and the process is repeated until a tank wall of the desired height is completed.  The resultant tank wall will have an outer layer of light, thermal in-sulating material, an inner layer of refractory material and a core of cememtitious material joining the two layers.

Abstract: ABSTRACT:              A video signal clamping circuit comprises a sum-ming circuit, an analogue-to-digital converter, a program-mable read only memory, a latch, a digital-to-analogue converter and an integrator. The PROM is addressed by the analogue-to-digital converter and produces a 4 bit output code which is dependent on the amplitude of the video sig-nal. This is stored on the latch and passed to the digital-to-analogue converter during a timing pulse applied to a terminal which occurs during the line blanking period. The digital-to-analogue converter produces an output which is stored on a capacitor in the integrator. The integrator output is summoned with the input video signal to clamp the video signal level to the reference voltage so that a clamped digital video signal is available from the output.

Abstract: ENGINE ANALYZER WITH SIMULATED ANALOG             METER DISPLAY ABSTRACT OF THE DISCLOSURE An engine analyzer for an internal combustion engine includes circuitry, under the control of a microprocessor, which senses parameters supplies digital signals indicative of those sensed parameters.  A raster scan cathode ray tube (CRT) display is controlled by the microprocessor to display a simulation of an analog meter having a cursor or needle which moves as a function of the digital signals.  When an analog display, such as a tachometer, is selected, the microprocessor controls the raster scan CRT to display a visual depiction of a meter having the appropriate range of values and having a needle which moves according to the measurements made by the system.  The microprocessor automatically changes the scale of the simulated meter as appropriate without operator intervention.  When operation within a predetermined range of values is required, the microprocessor causes the raster scan CRT display to produce a shaded area representing the range within which the needle should remain.

Abstract: ABSTRACT      This invention is characterized in that the usual time of non-heating after inputting of an input signal representing a start of cooking till return of relative humidity sensor (12) to its responsive state following clean-up of a humidity sensor element (13) is utilized as a substantial heating time for a heating load (2).  Thus, a heating means (3) is actuated for a predetermined time at the start of cooking to substantially heat the heating load (2) but an exhaust air (9) containing a steam generated from the load (2) during said predetermined time is exhausted by force immediately before return of said relative humidity sensor (12) to its responsive state, so that by the time the relative humidity sensor (12) returns to its responsive state the relative humidity has dropped substantially to the initial level prevailing at the start of cooking.  Therefore, the relative humidity which varies in response to a steam from the heating load (2) not attributable to heating can be accurately read out.  Especially, this invention permits a fail-proof automatic cooking of even a small heating load (2) in a short time.

Abstract: Dosing Pistol Abstract The dosing pistol is based on a manually actuated positive-displacement pump with a cylindrical housing (1), a product space (2) and a connecting rod (3) with the handle (5).  By pulling on the handle (5) the quantity of liquid located in the product space (2) is displaced and flows out forwards through the central bore (19) in the connecting rod (3).  The product space (2) is sealed off from the housing (1) by means of a funnel-shaped rub-ber diaphragm (10) resistant to medicaments and solvents. Non-return valves (22,20) are located at the inlet and outlet of the product space.  The sealing-off of the pro-duct space (2) by means of the funnel-shaped diaphragm (10) guarantees that the dosing pump is absolutely leak-proof, so that no liquid can pass outwards.  Moreover, a long life is ensured by means of this design.            (Figure 1)
